Description

Grain cleaning machine, The mechanism for feeding and distributing material to the grain conveyor of the grain cleaning machine, The drive of the mesh conveyor of the grain cleaning machine, The drive of the diametrical fan of the grain cleaning machine, The flow divider of the grain cleaning machine, The settling chamber of the grain cleaning machine.

Technical solutions relate to the agricultural and grain processing industries and can be used in grain cleaning machines.

Among domestic grain cleaning machines are known Pre-treatment machines SPO-100 of OJSC Voronezhselmash [Operating Instructions], MPO-100 OJSC GSKB Zernoochistka [Operating Instructions].

The disadvantages of these grain cleaning machines are:

- not uniform supply and distribution of material to the mesh conveyor;

- large total power of the grain cleaning machine;

- additional V-belt drives for drive mechanisms of the grain cleaning machine.

Separator of preliminary cleaning SPO-100:

- the loading auger does not provide an even distribution of material over the entire width of the mesh conveyor and the ingress of large impurities in the form of stones into the auger leads to jamming and stopping of the machine;

- torque transmission by working mechanisms is carried out through numerous V-belt drives;

- high power consumption of the grain cleaning machine;

- the use of a mechanism for injecting material into a belt-driven aspiration channel;

- the use of a mechanism for removing light impurities from a unit with a V-belt drive.

Thus, the storage hopper in the grain cleaning machines SPO100, MPO50, MPO100 is absent, the grain material is not distributed evenly and not in a continuous flow by the screw conveyor through the mesh conveyor. The mesh conveyor separates large impurities (stones, large straw impurities, sticks, etc.) from the grain stream and discharges them into the channel for large impurities.

Material waking down through a mesh conveyor falls at MPO50 on pitched boards, being compacted into one stream, which impairs the passage of air flow. At SPO100, MPO100, before entering the air channel, a multi-blade beater with metal blades is installed, cutting and throwing the grain flow into the air channel, damaging the grain material with metal blades.

From one electric motor located under the sedimentary chamber, by means of V-belt and chain transmission, torque is transmitted to all mechanisms of the grain cleaning machine.

The air flow removes light impurities from the material, such as damaged, diseased grain, dust, light straw impurities, etc.

Light impurities are removed from the sedimentation chamber by a screw with a shutter.

Grain cleaning machine. Known grain cleaning machine "OMEGA" company "DAMAS" (Denmark). Its design includes a hopper, which consists of the following elements: hopper housing. [http://www.selmashservis.ru/pages/omega/].

Its disadvantages are as follows, the hopper must match the performance of the previous transport equipment. There is no strict recommendation for the volume of the hopper, it is not uncommon during installation that an error occurs in calculating the volume of the storage hopper.

EFFECT: material is evenly distributed over the entire width of the working bodies of the machine and is fed with uniform speed.

The grain cleaning machine contains a storage hopper, which consists of a hopper body with dividers that ensure uniform distribution of material in the hopper.

In storage bins of other grain cleaning machines, dividers are not used.

In FIG. 1 shows the housing of the hopper 1 and the material dividers 2 directly.

The technical result is achieved by the stepped design of the dividers.

The following technical solutions are an integral part of the grain cleaning machine.

The mechanism of supply and distribution of material to the mesh conveyor of a grain cleaning machine.

The known mechanism of supply and distribution of material to the mesh conveyor of machines SPO-100, MPO-100, it consists of the following elements: loading screw, housing and valve [Operation manual].

Its disadvantages are as follows: there is no uniform distribution of material across the width of the machine, when large impurities in the form of stones get in, the screw is jammed and the machine stops.

EFFECT: material is uniformly fed across the entire width to the mesh conveyor with uniform speed.

The mechanism for feeding and distributing the material to the mesh conveyor of the grain cleaning machine, FIG. 2 consists of: a material flow shutter 1, a shutter lever 2, a load 3, a fixing screw 4, walls of the shutter material 5.

The walls are located at an angle relative to each other and form a passage for the material that closes the valve to which the lever is attached on which the load 3 with the fixing screw 4 is mounted.

The drive of the mesh conveyor of the grain cleaning machine.

Known drive mesh conveyor grain cleaning machine SPO-100, it consists of the following elements: V-belt and chain gears [Operation manual].

Its disadvantages are as follows: the drive is carried out by going several stages, accumulating power losses and increasing power consumption.

EFFECT: reduced consumed total power of a grain cleaning machine.

Consists of: a gear motor directly mounted on the drive shaft of the mesh conveyor.

The drive of the mesh conveyor of the grain cleaning machine, FIG. 3 is carried out by a worm gear motor 2 mounted on the shaft 1.

The drive of the diametrical fan of the grain cleaning machine.

Known drive diametrical fan of the grain cleaning machine SPO-100, it consists of the following elements: V-belt drive, pulley, belts. [Manual].

Its disadvantages are as follows: the use of long belts, pulleys of complex design from which further transmission of gear rotation is performed.

EFFECT: reduced consumed total power of a grain cleaning machine

The drive of the diametral fan of the grain cleaning machine consists of: an electric motor, two double-strand pulleys and two V-belts, all the drive energy is provided only to drive the diametric fan without loss to other drives.

The diametrical fan drive, FIG. 4 is carried out by an asynchronous electric motor by means of a V-belt drive. The figure 4 marked

1 - Pulley of a smaller diameter.

2 - A pulley of a larger diameter.

3 - V-belts.

4 - Electric motor.

Grain flow divider for grain cleaning machine.

There is a known mechanism for throwing in the material of the grain cleaning machine SPO-100, it consists of the following elements: beater, beater drive [Operation manual].

Its disadvantages are as follows: an additional mechanism requiring transmission costs and power consumption.

The technical result is the separation of the material flow and increasing the distance the material passes through the air stream.

The material flow divider consists of: a metal shelf dividing the flow of grain heap into two flows and increasing the distance the material passes through the air flow.

A material flow divider 2 is installed in the lower part of the coarse impurities cleaning unit of the grain cleaning machine 1, FIG. 5.

Sediment chamber of a grain cleaning machine.

A device for spilling light impurities from a grain cleaning machine SPO-100. Its essence is as follows: an additional mechanism is installed - a screw conveyor for removing light impurities from the unit [Operation manual].

Its disadvantages are as follows: an additional mechanism requiring transmission costs and power consumption.

The technical result is a simplification of the design.

It is achieved through the use of a funnel-like sedimentary chamber, consisting of four walls in the lower part of which a damper for light impurities is placed on which two counterweights are installed.

The weight of the counterweights is adjusted to the weight of the deposited impurities in the sediment hopper.

The damper spill light impurities 2 performs the discharge of accumulated impurities from the sediment hopper 1, Fig. 6 and return to the closed position using counterweights 3.

Grain cleaning machine operates as follows. The grain heap transported through grain pipelines enters the storage hopper. In the design of the storage hopper, dividers are used to evenly distribute the material throughout the hopper. The storage hopper ensures a constant, uniform supply of product to the mesh conveyor.

In the lower part of the coarse impurities purification unit, a material flow divider is installed, which ensures separation of the product for its further introduction into the aspiration channel. The output of light impurities from the sediment hopper is carried out by a damper with balances under the weight of accumulated impurities, which eliminates the use of additional actuators.

The mesh conveyor is driven by the worm gear motor of FIG. 3, the diametral fan also has an independent drive in the form of an electric motor.

The total power consumption is 4.55 kW.
