Description

The invention relates to agriculture and a harvesting system, in particular, to devices for drying agricultural grain products, preferably seed seeds.

The aim of the invention is to increase the productivity of the device and improve the quality of ventilation.

FIG. 1 shows the proposed bunker, a general view; in fig. 2 - air inlet valve in the working position; in fig. 3 - air shut-off valve in the off position.

The proposed ventilated bunker consists of a loading device, 1 perforated cylindrical body 2, a conical bottom 3, a perforated manifold 4, inside of which an air shut-off valve 5 is installed, made in the form of a cylinder of elastic material, with walls 6 having a thickening in the lower part, and corrugated a bottom 7, inside of which a locking element 8 is mounted with independent movement in the vertical direction. The cylinder 6 and the locking element 8 are held by the trestle systems 9, 10. The bunker also contains a main perforated cylindrical shell 11 with a conical bottom 12, installed coaxially between the housing 2 and a collector 4, an additional perforated cylindrical shell 13 with a conical bottom 14, installed coaxially between the body 2 and the shell 11, discharge unloading 15-17 with valves 18-20, duct 21, translucent casing 22 installed with a gap in relation to the housing 2, the fan 23. All elements of the hopper are placed on the frame 24.

The device works as follows.

When loading the hopper, the material is fed into the loading device 1, with which it is evenly distributed over the volume of the hopper. Drying the grain product

produced by coolant (air), injected or sucked (depending on time of day) by fan 23. In order to prevent air leakage, the air shut-off valve 5 is lowered by means of cables 9 and 10 to the level of grain, while the fan is temporarily turned off. After that, by means of a cable 9, the lowering of the valve 5 is stopped and the cable 10 smoothly lowers the locking element 8, which presses the walls of the valve 5 to the walls of the collector 4 and completely prevents air leakage past the valve 5.

In the daytime, the fan 23 is switched to the suction mode. At the same time, heated air is taken from the gap between the transparent sheath 22 and the body 2, which is painted in matt black. The heat carrier, penetrating the grain mound in the radial direction from housing 2 to collector 4 through shells 13 and 11.8, first of all dry the material in cavity B. The drying time is comparable to the average duration of sun baking during the grain processing period. When the material in the cavity B reaches the required humidity, it is discharged by opening the valve 20 in the drain 15. A moist grain product is poured out into the emptying space through the additional shell 13. The overall grain level in the bunker decreases

intensively, which allows the valve 5 to be lowered accordingly. At the same time, the locking element 8 is lifted with the help of a cable 10, the corrugated bottom 7 of the valve 5 is narrowed, which allows the valve 5 to be lowered. After setting the valve 5 to the desired level, the locking element 8. It presses the walls 6 of the valve 5 against the walls of the collector 4 and provides for the tight closing of the perforated collector.
