GENERAL INFORMATION ABOUT THE DEVICE
4 5
PURPOSE:
The SGC is designed for pre-cleaning of seed and commercial material: grain, leguminous,
vegetable, melon, fodder, as well as any bulk mixtures.
INTALLATION:
Installation of SGC is possible both as an additional unit for a series of ADS grain cleaners, and
as a separate unit as well.
It allows operation in closed areas, granaries, in the conditions of elevators, as well as in factories
where processing of agricultural products takes place.

2. MAIN TECHNICAL CHARACTERISTICS
Table 1
SGC is supplied to the consumer in a standard conguration. On the request of the customer,
the conguration of the SGC can be changed, at the same time a corresponding contract is
concluded.
The standard conguration includes:
* SGC - 1 pc.
* Operating manual - 1 pc.
* Calibration frame with mesh - 1 pc.
3. CONFIGURATION OF SGC
SGC is an auxiliary pre-cleaning device for aerodynamic grain cleaners, ADS-200, ADS-400 with a
frame and a calibration mesh installed in it. The mesh is xed on a removable frame, the mesh
moves with the help of a gear motor and a crank mechanism. At the same time, performing
back and forward movement of the frame with the mesh. The speed of rotation is controlled by
a frequency converter.
4. CHARACTERISTIC FEATURES
6 7
The operation of the unit consists in separating the grain from the rest according to the given
size during its passage through the calibration mesh. At rst, the grain is fed to the upper part
of the mesh, which moves with a small amplitude of oscillation, but with a high speed, during
the reciprocating movement of the mesh, the calibrated material is spilled. Large particles of
garbage that did not pass through the mesh fall into the receiving funnel for transfer to the
waste hopper. The calibrated material enters the receiving hopper of the ADS grain cleaner or
other equipment for further processing or transportation.

• The operator must have 1 group of admission for non-electrical personnel.
• Before starting work with the machine, the operator must comply with the following
safety requirements:
• Check the reliability of connection to the equipment of visible grounding (zero
protective) conductors, the presence and reliability of fastening of grounding (zero
protective) contacts, plugs and sockets, plug connectors;
• The total resistance of the grounding devices of all repeated groundings of the neutral
wire of the power supply line must be no more than 10 Ohms. (According to clause
1.7.103 of the Rules for the use of electrical devices).
• Connection plugs must be made in such a way that it is impossible to insert them
into sockets with a higher rated voltage than that indicated on the plugs. Before
connecting, it is necessary to make sure that the voltage supplied corresponds to
the socket of the connection. When connecting the equipment, do not allow cables,
power supply wires to be stretched and tangled, and do not allow them to be loaded
with things and cargo. Do not allow direct contact of wires and cables with hot, wet
and oil-treated surfaces and objects.
• When working with treated seeds, it is necessary to conduct a timely medical
examination and provide personnel with personal protective equipment.
• During the operation of the SGC without aspiration suction of waste, the operator
must work with goggles that protect him from dust and in a respirator
Installation (disassembly) of SGC is carried out only after
disconnecting the equipment from the electric current. Installation
(disassembly) of SGC is carried out only on a at, immovable surface
in compliance with all standards and requirements of the PTB for
installation work. Installation and adjustment of equipment is
performed only by certied specialists!
7. SAFETY TECHNIQUE ATTENTION!
IT IS FORBIDDEN!
• To operate SGC without learning this operation manual;
• To operate SGC without grounding;
• To operate SGC if the voltage in the network does not meet the requirements,
namely, for a voltage of 220V +- 10%, for a voltage of 380V +- 10%;
• To operate SGC if protective elements of moving parts are removed;
• To open nodes and blocks that are under voltage;
• To make changes to the program of the frequency converter;
• To operate SGC for the personal who doesn’t not have 1 group of admission for non-
electrical personnel;
• To operate SGC in places where atmospheric precipitation may fall on it (rain, snow,
fog, dew, and the like).
Installation is carried out using a lift or forklift or by personnel trained by the manufacturer.
Recommendations for installing SGC
During the installation of SGC in hangars, access from all sides should be at least 1200
mm for ease of maintenance. The technological gap above the SGC should be at least
1500 mm.
SGC installation procedure before operation:
• Install SGC at the place of further operation.
• During the installation of SGC on ADS grain cleaners, SGC is installed on top of the
receiving hopper, using loops depending on the model of the separator.
• During the installation of SGC as a separate unit, SGC is installed in a specially prepared
place or bunker.
