Description

one

The invention relates to agricultural machinery and is intended for use in the post-harvest processing of flax heap.

A point of drying and processing flax heap is known, which contains a loading and unloading device, a rotary dryer with an unloading device, a belt conveyor and a heap processing machine with a threshing device l.

A flax heap drying and processing center is also known, which contains a pick-up device, a conveyor dryer, a cross conveyor belt with upper and lower roller supports and a pile processing machine with a loading tray and a threshing drum, podbara-. a bath and a crash set under a concave,

A disadvantage of the known devices is increased damage.

seed, resulting in deterioration of their germination.

"

The purpose of the invention is to reduce the damage of seeds.

This goal is achieved by the fact that the loading tray is made in the form of a string separator with an inclined tray, the discharge part of which

JP is mounted above the screen.

In addition, one of the upper rollers of the transverse belt conveyor is grooved; the others are straight, with the groove, the 5 and the receiving ropiko-pores installed alternately, while the direct rollers are provided with longitudinal ribs and are driven from the lower rollers.

20 In FIG. 1 shows a block diagram of the item drying and processing flax heap; in fig. 2 shows section A-A in FIG. one; on (1) ig. 3 shows a section BB in FIG. 1J in FIG. t is a section bb of FIG. 31; FIG. section GGG fi g. 3. Point of drying and processing of flax grove contains receiving-loading device 1, conveyor dryer 2, transverse belt conveyor 3, temporary processing machine 4, loading elevator 5, bunker 8 for seeds, pneumatic conveyors 7 and 8 chaff, and confusion. A pick-up device includes a receiving chain-slaty conveyor 9, conveyor-leveling device 10 and loading gear drum 11. Dryer 2 is equipped with a heat fan unit 12 and includes a mesh belt 13, a gas distribution system in the form of dividing partitions, a cooling fan 15 and a discharge valve a toothed drum 16. A continuous belt transport 3, which contains a belt, the working branch 17 of which is supported by upper roller carriages, some 18 of which are grooved and the other 19 are straight grooved rollers Picks 18 and straight rollers 19 alternate. The ribbon branch 20 is biased over the straight lower roller coils 21. The straight upper roller carriages 19 are provided with longitudinal ribs 22 and are driven 23 from the lower roller carriages 21. The heap processing machine 4 includes a feed stream 24, a threshing drum 25, a concave 26, a screen 27, baffle beater 28, straw walker 29, roller grater 30, cleaning 31 and elevator 32o The loading flow 2k is made in the form of a string separator 33 with an inclined tray Z. The threshing drum 23 is installed at the outlet of the separator 33, on above the screen 27. The device works as follows. The flax heap brought from the floor is dumped onto the receiving conveyor which moves it forward. Tra porter leveling 10 aligns the heap layer, throwing the excess on the backside, after which the heap is evenly fed to the loading gear drum 11v. air supplied by a heat pump unit 12 and dried. At the end of the dryer, the pile is cooled by the atmospheric air supplied by the fan 15 and goes to the discharge drum 16. The drum 16 delivers the pile to the belt conveyor 13. Moving on the belt, the layer of the pile deflects in the transverse direction above the grooved rollers 18 and leveled off the lines. roller rollers 19 A similar movement of the pile occurs in the longitudinal direction due to the alternation of grooved and straight roller supports. As a result, the stalks of confusion are moved relative to each other, freeing the passage of the free seeds contained in the pile, broken boxes and whole boxes without pedicle. A more intensive stirring of the LOT and filtration of free seeds through it is achieved by shaking the tape while interacting with roller supports equipped with longitudinal ribs 22. The bundle thus separated from the conveyor goes to the string separator 33. The bulk fraction falls to the pallet 3 and flows by gravity from it to the screen of 27, and after it to the cleaning of 31. The confusion with the remaining boxes, mainly with pedicels, boxes comes along the stringed surface to the threshing drum 25. The extracted seeds, sashes -,. collapsed pods and other small fractions fall through the concave 26 on the screen 27, and the confusion with the breakaway beater 28 is directed to the straw walker 29 and then to the pneumatic conveyor 8 the confusion. The bulk mass (seeds, seed and chaff) entering the cleaning 31 leaves the machine, and the intact pods are fed by an elevator 32 to a grater apparatus 30, after which the mass enters the screen and cleaning. The chaff by the pneumatic conveyor 7 is removed beyond the point, and the seeds with noria 5 are fed to the bunker 6. The seedings containing small weed seeds and heavy mineral impurities are removed and destroyed as they accumulate.

The point of drying and processing of flax heaps, providing a differentiated mechanical effect on the components of the flax heap, minimizes damage to free seeds, which have a low resistance to damage due to drying, thereby reducing the seed quality and reducing losses from crushing.
