Description

The invention relates to agriculture and can be used in complexes for the post-harvest processing of grain. In households with a large gross grain harvest.

The purpose of the invention is to increase production and serviceability.

FIG. 1 shows the scheme of the complex, view from the side of the loading elevator; fig 2 is the same plan; in fig. 3 is a view A of FIG. one; 4 shows a grain conduit of a transporting device for feeding grain from a elevator to a grain cleaning machine; figure 5 is a diagram of the drying device SCH1YA grain

The grain-cleaning complex contains a bunker 1 of cleaned grain and a reserve bunker 2, which are elongated rectangular in terms of a capacity of at least 500 tons each and are installed adjacent to each other in a single unit on metal supports 3. The bottom of each of these silos is gate unloading dampers (not shown) placed along the entire length of the bottom. From above, bunkers 1 and 2 are closed with a common roof 4. Under the roof 4 across these bunkers there are galleries in which you place conveyor belts 5 and 6, which are connected to grain cleaning machines 7 and 8 (for example, brand ZSM-100, 100 t / h), and the other through grain-water 9 - with the output of the loading elevator 10 (for example, the NTs-17.5 brand, with a capacity of at least 175 tons / h). Grain lines 9 and conveyors 5 and 6 are transporting devices for feeding grain from elevator 10 to machines 7 and 8.

The Nori 10 is installed on the side of the reservoir bunker 2 adjacent to it and is located L on the back of mine 11. The output of the elevator 10 is connected to grain mills 12 for feeding grain to the reserve bunker 2, and the input is to grain lines 13 for feeding grain from Bunker 2. A car lifter 14 and a tipper 15 trailers are installed above the roll mine 11.

The bunker 1 of the cleaned grain through the grain lines 16 for supplying the cleaned grain to this bunker is associated with the additional noria 17 installed at the bucket weir 18, which is intended to receive incoming

from maggik 7 and - 8 gravity flow, purified grain.

Machines 7 and 8 are mounted in frame 19 on separate supports 20, these machines have one or more bins of 21 wastes.

Under the roof 4, each grain conduit is made of the upper 22 and lower 23 parts (Fig. 4) spaced apart from each other and rigidly connected to the ribs 24 evenly spaced around the circumference of the grain conduit, with a rotary valve 25 installed in the lower part 23 Thus, between the ribs 24, openings 26 are formed to exit the excess grain. The grain lines 9 are provided with a device for supplying the excess grain to the reserve bunker 2, which is made in the form of pitched planks 27 for each grain lines 9 installed under the holes 26 at an angle to the longitudinal axis of the grain wire,

A drying device containing a heater 28 connected to a pipe line 29, which is placed along the backup bin 2 in its upper part and made with radial holes 30 on the length bounded by the hopper 2 poles, is used to dry the high-moisture grain supplied to the current. installed gable board 31 (Fig. 5), located under the output kondami grain lines 12.

The processing of grain on the proposed complex is carried out in the following manner.

A car (not shown) with grain arriving from the floor drives into the car raiser 14, and the receiver goes to the tipper 15. Grain is unloaded into the bulkhead 11, from where noriya 10 goes through the grain lines 12 to the reserve bin 2 and simultaneously along the grain lines 9 - to conveyors 5 and 6 and further to the grain cleaning machines 7 and 8. To eliminate the overload of conveyors 5 and 6, the shutter 25 partially overlaps the flow area of the grain lines 9, and the grain part through the holes 26 of the honey ribs 24 is dropped onto the ramp 27, which rolls into the standby bunker er 2. The cleaned grain flows by gravity into the burial ground 18 and the additional norium 17 is fed through grain lines 16 into book 3.

Ker 1, a waste enters the hopper 21. To transport grain to the elevator, a car with a trailer pulls up under the bunker 1 of the cleaned grain, then all the dampers on the bottom of the bunker 1 are opened, and the car with the trailer without any additional maneuvers is fully loaded in a short time.

When feeding grain for cleaning from the hopper 2, when the priming head 11 is empty, it is necessary to open the grain lines 13 and close the grain lines 12. In this case, the grain flows through the grain lines 13 to the elevator 10 and then to the grain cleaning machines 7 and 8.

1184

Such units as a bunker 2, grain lines 13, heater 28, nori 10 and grain lines 12 can be used for cyclic drying of grain. At the same time, the grain passes through the grain lines 13, through the line 10 and the grain lines 12, from which it falls onto the gable boards 31, rolled down from them into the bunker 2, and is blown with hot

air through the holes 30 of the pipeline 29. The number of revolutions of the grain depends on its humidity, the power of the heater and the task of removing moisture in the grain mixture,

In winter, bunkers can be used as storage for forage.
