II. Precautions
1. Precautions on the use of equipment
①Because the surface temperature of the working devices and pipes of the asphalt sprayer during the working
process (including spraying, heating, and filling asphalt and so on) is very high, please wear work clothes,
heat-resistant gloves and protective caps before work to avoid scald.
②Only add asphalt that does not exceed 60% of the rated capacity before first use of the asphalt sprayer.
③Before filling high-temperature hot asphalt (including hot asphalt, SBS modified asphalt and other
high-temperature asphalt) to the asphalt tank, the water in the asphalt tank must be removed completely,
otherwise the cold water will vaporize and expand sharply if in touch with high temperature hot asphalt,
causing risk.
④After using emulsified asphalt and converting it to use high temperature hot asphalt (including hot asphalt,
SBS modified asphalt and other high temperature asphalt), all the emulsified asphalt in the tank and
pipeline must be removed completely, or the moisture in the emulsified asphalt will vaporize and expand
sharply if in touch with high temperature hot asphalt, causing risk.
⑤When converting to the emulsified asphalt after just using the high-temperature hot asphalt (including hot
asphalt, SBS modified asphalt and other high-temperature asphalt) or converting to the high-temperature hot
asphalt (including hot asphalt, SBS modified asphalt and other high-temperature asphalt) after just using the
emulsified asphalt, the remaining asphalt in the asphalt pump, asphalt pipeline, asphalt spray rod, asphalt
nozzle and asphalt tank must be removed completely, or water will vaporize and expand sharply if in touch
with high temperature hot asphalt, causing risk.
⑥During the transportation and spraying processes of the asphalt sprayer, do not stand on the rear working
platform of the truck.
⑦After filling high-temperature hot asphalt, for your safety, non-operators must stay away from the asphalt
sprayer more than 5 meters.
⑧In order to obtain a satisfactory spray quality, the temperature of the asphalt added has the following
requirements: for the common heavy-duty road, the hot asphalt spray temperature is above 160°C; SBS,
SBR and other modified hot asphalt spray temperature is above 185°C; SBS, SBR and other improved
emulsified asphalt (including emulsified asphalt) is between 65-85°C.
⑨In order to ensure the normal use of equipment, the allowable temperature of the heat transfer oil is ≤
250 °C.
⑩When asphalt tanks are filled with emulsified asphalt, sediments at the bottom of large storage tanks must
not be added to the asphalt sprayer, otherwise the truck will not work.
⑪When the asphalt pump sticks, it must not be forced to start. It must be heated to make the asphalt melt
and loose before it can work.
⑫When the power take-off is engaged or disengaged (that is, the power takeoff starts to work), the chassis
pressure must be more than 6 kg (greater than or equal to 0.6 MPa) to step down the automobile
clutch (it is best to turn off the car), otherwise the power take-off and the car transmission will be
damaged.
⑬During the transportation of the asphalt sprayer, the power take-off must be disengaged and the master gas
valve of the gas source must be closed, and the burner must not be used while the truck is traveling.
⑭The reduction gear is engaged at the high-speed position (that is, the gear ratio is 1:1 without deceleration),

IKOM Construction Machinery Intelligent Asphalt Distributor
7
and at the low-speed position. To shift the gear, this can be done only when the truck is running at the
low speed or stops and when the car clutch is stepped down.
⑮When all asphalt in the entire truck is sprayed completely, be sure to clean the asphalt pump, the asphalt
pipeline, the asphalt spray rod, and asphalt nozzle.
⑯After the spraying work is completed every day, the remaining asphalt in the tank must be exhausted to
avoid unnecessary problems caused by the solidification of the asphalt.
2. Precautions on the use of chassis
Within 2500KM traveling mileages of the new truck, you must go to the special repair station of the
car chassis to do “maintenance handling”; otherwise, the manufacturer of the chassis of the vehicle will
not provide the three-guarantee service.
As the national automobile regulations are continuously updated, our company advises customers to apply
for motor vehicle licenses within one month of buying a new truck.

IV. All system structures and working principle
1. Control system
The electrical control system is divided into two parts: DC circuit (DC24V, chassis power supply) and AC circuit
(AC220V, generator set power supply).
DC circuit consists of power take-off, reducer, cooler, hydraulic reversing valve, rear nozzle lift, rear work light
control circuit and automatic control system circuit.
The AC circuit consists of a generator, a burner, and a heat transfer oil motor circuit.
See the intelligent electrical schematic diagram (see PXX Figure 1) for details.
2. Hydraulic power and transmission system

Table 3 Hydraulic power and transmission system parts table
The power take-off is a two-axis mechanical gearbox structure. The input gear meshes with the third gear of the
intermediate shaft of the automotive gearbox and outputs power from the output shaft. The fork is pushed by the
high pressure air to achieve the engaging and disengaging of power takeoff through the meshing gear sleeve.
The sequence of the power transmission between the hydraulic power and the transmission system is as follows:
Gearbox (output shaft) → Power Take Off (power received from the gearbox and transmitted to the hydraulic
pump) → Hydraulic pump (converts input mechanical energy into kinetic energy of hydraulic oil ) → Hydraulic
oil → Hydraulic motor (converts input hydraulic oil kinetic energy into mechanical energy of output shaft) →
Coupling (elastic connection) → Asphalt pump (converts mechanical energy of input shaft into kinetic energy of
asphalt).

4. Asphalt pipeline cleaning system
The pipeline cleaning system is divided into diesel cleaning and high pressure air flushing.
The diesel cleaning part consists of a diesel tank (tube), an oil inlet ball valve, and piping. When diesel is used for
cleaning, the asphalt pump rotates at a low speed, and the diesel is discharged through the oil inlet copper ball
valve, the asphalt filter, the asphalt pump, and the asphalt nozzle.
The high-pressure air flushing part consists of a gas cartridge, a one-way valve, an air valve, and other components.
Check valves prevent asphalt from returning to the air reservoir. When the high-pressure air is used for flushing,
close the diesel oil inlet copper ball valve; when the asphalt pump rotates at a low speed, open the main pipeline air
valve, wo high-pressure air passes through the valve, the asphalt filter, the asphalt pump, the post-spraying pipeline,
and the asphalt nozzle, to discharge the asphalt and diesel in the pipeline. See Figure 7, Figure 8 and Figure 9 for
details.

5. Heat transfer oil and heating system
Asphalt heat transfer oil and heating system consists of heat transfer oil circulation heating system and burner
heating system.
(1) Burner heating system
The burner heating system consists of a U-shaped combustion chamber, a heat transfer oil heating chamber, a fuel
tank (chassis fuel tank), a burner, and a heat transfer oil temperature control box. The diesel fuel is sucked from the
chassis fuel tank through the filter to the burner and mixed with air. After atomization, it is injected into the
combustion chamber and the exhaust gas is discharged from the chimney. The heat generated by combustion in the
combustion chamber heats asphalt in the surrounding tank and the heat transfer oil in the heat transfer oil heating
chamber. The flame size and target temperature are controlled by the heat transfer oil temperature control box. See
Figure 10 and Figure 11 for details.

(2) Heat transfer oil circulation heating system
The heat transfer oil circulation heating system is composed of a heat transfer oil motor, a heat transfer oil pump, a
heat transfer oil expansion tank, and an asphalt heating circulation pipeline. Through the heat conduction oil
circulation, not only the asphalt inside the tank can be heated and insulated, but also the asphalt pump, the asphalt
filter and the after-spray can be quickly heated, as shown in see Figure 7 and Figure 8.

V. Use and operation process
The correct use of asphalt sprayer and compliance with various operating procedures can give full play to the
mechanical efficiency and maintain good mechanical performance, thereby increasing productivity and reducing
construction costs.
The use and operation of intelligent asphalt sprinklers are mainly carried out according to the following process:
Fig.14 Operation flow chart of asphalt sprayer
1.Preparation before operation
Carefully check the following items and add the asphalt to the asphalt tank only when those
requirements are met.
1.Check if the steering, braking, electrical and running gear of the vehicle are working properly and reliably;
2.Check the engine lubricating oil, fuel and cooling water is sufficient and is not leaked;
3.Check whether the generator lubricant and fuel are sufficient;
4.Add appropriate amount of diesel oil (about 60 to 70 liters) to the diesel fuel tank (tube);
5.Place the piping system valves in the closed position (especially the diesel fuel inlet ball valve and the air
valve must be closed, otherwise the asphalt backfill into the air reservoir and the diesel tank will cause failure);
6.Check whether the rear spray pipes or portable nozzles and nozzles are unblocked and whether the asphalt
pump can be rotated;
7.Before starting the engine, the gearbox and power take-off must be placed in the neutral position;
8.Start the engine, and engage the power take off, and check the hydraulic system is working properly, and
check all electrical switches work normally;
9.Check whether the generator set is working properly, and whether the heat transfer oil pump can run
normally, and whether the burner can ignite normally.
2.Fill asphalt
Filling asphalt includes the filling by the external equipment and the self-suction filling by the asphalt pump.
Method 1 Filling by the external equipment
After check and confirm the sprayer in the fault-free condition, drive the vehicle under the asphalt filler pipe, and
place all the valves in the closed position first, and open the small cap of the filler port on the top of the asphalt
tank (P3 in Figure 1-32), and put the filler pipe into the tank , and start to fill asphalt, and then close the filler cap
after filling is completed.
The following requirements shall be met when filling asphalt:
1.Asphalt can not be added too full, and the asphalt level added can be between 30 and 40 cm from

IKOM Construction Machinery Intelligent Asphalt Distributor
18
the filler port, especially for hot asphalt, so as not to overflow;
2.In order to avoid too long heating time, it is very unfavorable to equipment life and work efficiency.
The filling asphalt must meet the following temperature requirements: the temperature of ordinary
heavy-load hot asphalt pavement is above 160°C; the temperature of SBS and SBR modified hot
asphalt is above 185°C; Temperature of the SBS and SBR modified emulsified asphalt is between
65-85°C;
3.When the new car is used for the first time, be sure to clean up the accumulated water in the tank,
otherwise it will cause risk, and the filling asphalt must be less than 60% of the volume of the asphalt
tank;
4.After using emulsified asphalt and before filling hot asphalt, be sure to discharge the remaining
emulsified asphalt in the sprayer completely, otherwise it will cause risk. Conversely, the same steps
are available for filling emulsified asphalt after using the hot asphalt;
5.Always check if the vents are unblocked.
Method 2 Self-suction filling by the asphalt pump
Fill asphalt into the asphalt tank through the self-suction by the asphalt pump on the asphalt sprayer.
The following requirements are met when filling asphalt:
1.The connection of the self-suction hose must be tight, and the asphalt filter cover must be tightly
closed. No air leakage is allowed.
2.The diesel fuel inlet ball valve and air valve must be closed tightly. Otherwise, they will not work
and may even cause danger.
3.The liquid level of the asphalt storage tank must be higher than the center of the asphalt pump and
the distance is less than 5 meters;
4.Asphalt pump idle time can not exceed 2 minutes;
Other precautions are same with those described in the method 1.
The operation flow of the Method 2 is as follows:
(1) Preparation
Check whether the entire working system of the vehicle is working properly:
①Check whether the indicators of the vehicle instrument are normal;
②Check whether the oil volume in the fuel tank is sufficient;
③Check whether the hydraulic oil is sufficient;
④Power take-off (P.T.O) switch is at the "OFF" state and the reducer switch is in the "QUICK" state.
Park the asphalt sprinkler on the edge of the asphalt pool and use a hose to connect the asphalt tank outlet
with the self-suction port of the asphalt sprinkler.
Fig. 15 Self-suction port diagram

(2) Start the vehicle
Start the engine of the vehicle and check the gas pressure gauge on the car dashboard. When the pressure is ≥
0.6MPa, turn off the engine of the vehicle and step down the clutch to make the vehicle gear in neutral. Turn the
Power Take Off (P.T.O) switch of the front console in the cab to "ON" and start the vehicle engine again,
keeping the engine speed at 1000 rpm.
Fig. 16 Power takeoff switch and automotive gas pressure gauge diagram
(3) Open and close the valve
Open the self-suction valve and open the small asphalt circulation return valve, and close the remaining
asphalt pipeline valves.
Fig. 17 Asphalt pipeline valve position diagram
(4) Turn on the rear control cabinet power and open the asphalt pump
Turn on the power switch (POWER--“ON”) of the rear control cabinet, and turn the foreground-background
selector switch to the (SWITCH--BACKGROUND) and turn on the asphalt pump switch (PUMP--“ON”), and
adjust the asphalt pump speed (150rpm) to start the self-suction operation.
P.T.O Switch
Truck Piezometer

Fig. 18 Rear control cabinet control panel diagram
During the self-suction operation, observe whether there is asphalt flowing from the small
asphalt circulation return port through the manhole; if no asphalt flows from the return port when the
asphalt pump is rotating for 2 minutes, close the asphalt pump timely and check the asphalt pipe, the valve
and the filter and other components for cogging or air leakage and check whether there is asphalt in the
storage tank. As the asphalt pump is working at the high temperature, the internal gap is larger, so the
asphalt pump will be seriously worn by a long-term self-suction. Therefore, the company recommends to
use method 2 as little as possible.
3.Transport
When filling asphalt to the target volume in the asphalt sprayer, disengage the car clutch and turn the reducer
switch to the “QUICK” state, and drive the vehicle slowly to the construction site at the medium speed.
Precautions on transportation:
(1)In the process of transportation, do not stand on the rear working platform;
(2)During the transportation of the asphalt sprayer, disengage the power takeoff and close the controller of the
power takeoff, and close the asphalt pipe inlet and outlet valves and heat transfer inlet and outlet, and stop the
heat transfer oil pump; do not use burner while the vehicle is driving.
(3)Close the master switch of the air source of the working system in the transportation of the sprayer.
(4)As the mass of the truck filling with asphalt is too large, do not drive or urgently brake the vehicle at high
speed as much as possible.
4.Asphalt heating
After transporting to the construction site, observe the thermometer of the asphalt tank; if the temperature of the
asphalt in the asphalt sprayer can not meet the requirements of the spraying operation (for details of the asphalt
spraying temperature, refer to the Article 8 of Precaution on P5), the asphalt must be warmed. as follows:
(1)Park the asphalt sprinkler truck on the flat ground, and confirm that the amount of asphalt in the asphalt tank
reaches above the warning line, and open the cover of the front chimney of the tank body.
(2)Start the generator, as shown in Figure 19
①Turn the engine switch to "ON";
②Open the generator throttle to the maximum;
③Pull the start handle outward until the generator starts;
④Adjust the throttle size so that after the engine runs smoothly, check the voltmeter reading until the
voltmeter reading is ≥220V.
