The invention relates to agricultural machinery and can be used in a system for threshing grass seed.

The purpose of the invention is to increase productivity.

FIG. 1 shows a diagram of the threshing line of grass seeds; in fig. 2 - dryer, top view; in fig. 3 - dryer, section A-A in figure 2; Fig. 4 is a side view of the dryer air duct; in fig. 5 - vertical pneumatic canal, top view; in fig. 6 shows the section of the ventilation duct and the vertical pnevmokal, top view; in fig. 7 shows the ventilation duct, section Bb in FIG. 6

The threshing line for grass seed has a dryer 1, which includes ventilation ducts 2 with fans 3, mounted on the trolley 4 with the possibility of moving along the inlet sections of the ventilation ducts 2, additional vents 5, as well as a winch 6. In between The ventilation channels 2 and 5 have vertical pneumatic channels 7, the pipeline 8 connecting them with the lower part; the ventilation channels 2 are located tangentially to the inner surface of the pneumatic channels 7 and are filled with spiral-shaped channels. Vertical pneumatic channels 7 are equipped with

van combine SK-5 Niva. A baler 21 connected by a sloping chute 22 is mounted behind the combine 20.

 with a cart 23, a cleaner 24 heaps, a fan 25 with a cart 26 and a seed conveyor 27.

Line threshing seeds of herbs works as follows.

10 The mowed grass on the weight in the carts is delivered to the dryer 1 in the zone of the truck 18. Here the mowed grass on the mass is lifted out of the carts 15 by means of the lifting and transporting means 18 from the carts and after an even fit vented masses turn on fans 3 and air is supplied to the ventilation ducts 2. In this case, air can be supplied to the ventilation ducts 2 by one or several fans 3, which periodically displace trolleys 4 along the inlet sections of the ventilation ducts 2 and 5 using a winch 6 ..

Air flows along the passage through the cavity 11 of the ventilation ducts 30 of the channel 2 and through the additional ventilation ducts 5 rush up into the grass mass and block moisture from it.

Polo air flow

gate valve 9. Ventilation ports of 12 ventilation ducts 2, with

the channels 2 are separated by a partition 10 in the horizontal plane into an upper longitudinal cavity 11 and a lower longitudinal cavity 12. The partition 10 consists of two parts fixed to the walls of the ventilation channels 2 by means of hinges 13 and hydraulic cylinders 14.

The ventilation channels 2 and 5 as well as the vertical pneumatic channels 7 are covered with a wooden grate 15 on top, and the entire dryer is protected from above by precipitation by a canopy 16.

The ends of the ventilation ducts 2 and 5, remote from the fan 3, are connected by a conveyor 17, for example, a tape conveyor.

Under the canopy 16, a truck 18 is located, for example, a grapple overhead crane, and a feeder feeder 19. A threshing-separating device 20 is located behind the feeder-feeder 19, which can be used as

by means of butterfly valves 9 through pipelines 8, the tangent to the inner spiral-shaped surface of the valve-pneumatic channels 7 is fed. Here an upward swirling air flow is formed, rushing into the dried mass.

If necessary, several vertical pneumatic canals 7 can be put into operation, they are located at different locations in the dryer, or air fed into the cavity 12J can be passed through one pneumatic canal 7. Этс | allows you to adjust the intensity of the regime in different parts of the drying mass.

Seeds that fall off during the drying process into channels 2 and 5 are fed by pneumatic flows through these channels to the conveyor. 17 and further to the heap cleaner 24, When threshing, all n alfalfa, a heap after the transporter 17 is passed through a clover filter to separate out 515

neither seed from the bobby and then fed to the cleaner of the heap 24.

Seeds spilled into the vertical pneumatic channels 7, under the action of their own weight, are fed by a spiral-like surface into the cavity 1 2 channels 2 and are transported by them into the conveyor 17.

After the end of the drying process, the ventilators 3 are turned off and with the help of the truck 18, the dried grass mass is loaded into the feeder-feeder 19, from which herbs are fed to the threshing-separating device 20, where the seeds are threshed. Then The non-grain part of the crop, in particular the straw, enters the baler. Here it is pressed into bales, which are loaded into the carriage 23 along the inclined chute 22. The floor passes through the cleaner of the pile 24, where seed is released from it. Then, the floor of the fan 25 is loaded into the cart 26. Grass seeds from the threshing-separating device 20 and the cleaner of the pile 24 by the conveyor 27 is fed for post-harvest processing.
