RU152871U1 - MOBILE GRAIN CLEANING DEVICE - Google Patents

Abstract

A mobile grain cleaning device comprising a platform, a loader and a grain cleaner installed on it, characterized in that the grain cleaner is made in two stages, including cleaning using a mesh conveyor and air flow; further comprises a grain thrower mounted on the platform.

Description

The technical solution relates to the agricultural and grain processing industries and can be used in grain cleaning machines.

Among domestic grain cleaning machines, the Self-moving OVS-25 Heap Cleaner of Voronezhselmash OJSC is known [Operation manual].

The disadvantages of this heap cleaner are:

- not a lot of material cleaning performance;

- not a large storage distance of the shoulder;

- Shipment of small impurities in one direction.

Self-propelled OVS-25 heap cleaner:

- The formation of a pile of pure grain is carried out on the right side of the unit at a short distance, this does not allow forming a large pile of grain in one pass to save the warehouse territory and time for its formation, storage and shipment;

- The formation of the waste shoulder is carried out on the left side of the aggregates; the formation of the shoulder cannot be changed, which is not always applicable when a different technological scheme for cleaning and storing the product is required;

- With the increasing modern technologies of cleaning and product sales, not a large capacity of the purifier with a large total power consumption (9.5 kW).

The technical result is an increase in the efficiency of a mobile grain cleaning device.

Mobile grain cleaning device (Fig.) Consists of:

1. Loader;

2. Two-stage grain cleaner, including cleaning using a mesh conveyor and air flow;

3. Platforms;

4. Grain thrower.

Loader, pos. 1-loading inclined conveyor and two perpendicularly located feeders pivotally connected to the lower head of the conveyor.

Grain cleaner, pos 2-grain cleaning machine.

Platform, pos. 3-metal structure on which all components and mechanisms of a mobile grain cleaning device are mounted.

Zernometatel, pos. 4-trimmer with trimmer pipe.

The main nodes of a mobile grain cleaning device include nodes of a grain thrower, a grain loader with a transitional unit providing uniform distribution of material to the mesh conveyor and its entry into the pneumatic channel.

Mobile grain cleaning device operates as follows. The grain heap stored in the shoulders is moved by feeder scrapers to the center of the lower part of the loading inclined conveyor. The conveyor scrapers capture the material and feed it onto the adapter with dividers, which evenly distribute the material along the mesh conveyor for its further introduction into the suction channel. The removal of light impurities from the sediment hopper is carried out by a worm gear motor mounted on the conveyor shaft. The cleaned grain material enters the endless tape of the trimmer and is sent through the trimmer pipe to the desired location for storage or loading of vehicles.

The mobile grain cleaning device comprises an adapter of FIG. 5, which consists of an adapter housing with dividers that ensure uniform distribution of material along the working body of the mesh conveyor.

As a result, the material is evenly distributed over the entire width of the working bodies of the machine and is fed with uniform speed and performance given by the loading conveyor with feeders.

In other grain cleaning devices adapters with dividers are not used.

The result is achieved by dividing the inclined wall of the adapter by dividers into uniform sectors along which the material is evenly distributed on the working body of the grain cleaning machine.

The mobile grain cleaning device is equipped with a conveyor drive (screw, scraper) for removing light impurities from the sedimentation chamber of the grain cleaning machine.

An independent drive from the gearmotor gives a quick change in position (left, right) of the discharge of light impurities.

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

The conveyor drive (screw, scraper) for removing light impurities from the sedimentary chamber of the grain cleaning machine is carried out by a worm gear motor mounted on the shaft.
