Description

Basically auth. St. No. 234026 describes a combine harvester designed to separately collect biologically more valuable, seed and remaining grain for food. The combine has two threshing devices, the first of which is installed on the header and from which the threshed grain by transporting devices is fed into a separate bunker, mine clearing.

In the proposed combine, in order to allow the heap from the first threshing device to be cleaned and processed together with the second threshing device from the second threshing device, the transnorting devices for feeding grain into the hopper from the first threshing device include a screw with a rotary bottom above the cleaning or over its page board or flap. Leveling pins are installed between the combine bunkers in their upper part.

The drawing shows schematically the described combine.

The harvester includes a reaper with a reel / mounted on it by the cutting apparatus 2 and a threshing apparatus, which includes a pin or bilny drum 3 with receiving and pneumatic beaters and a concave 4. For the threshing apparatus there are set a mass of cheeks 5 and a floating

conveyor 6 inclined camera. Below the concave there is a receiving chamber 7 with a transnorter 8 for feeding the grain pile to the converging augers 9. The inclined camera has a slatted bottom W. With the augers 9 grain, the mass is fed to the conveyor 11, which directs the mass to the cleaning. The second threshing apparatus includes a threshing drum 12 with a concave 13, a receiving

the beater 14 and the bumper beater / 5. In the case of the thresher there is a straw walker with 16 and a cleaning, including a page board 17 with a grill, upper 18 and lower 19 louvres. In the lower part of the cleaning, a grain auger 20 is installed, feeding the grain to the elevator 21, and a grain auger 22, feeding the unmilled weight to the elevator 23, ending with the upper auger 24. The cleaning sieve is blown by a fan 25.

any methods and mechanisms can be used for collecting straw, for example, a stacker 26 with a straw crusher 27 and a pollenabivatel 28, feeding the chaff to the stacker with an upper sieve extension 29 29. Elevator 21

the grain is fed by screw 30 into a hopper 31 divided by a partition into two sections. The rear section of the bunker has an unloading screw 32, and the front section has an unloading screw 33. Both sections are interconnected by means of shnesection into the front section. The front section can be used to collect biologically valuable grains. For this purpose between the conveyor // and the elevator 35 is installed auger 36 with a rotary bottom 37 of the casing. If the bottom of the casing is set to the position indicated in the drawing by a solid line and the cheek is turned off, the mass is poured through the auger onto the page board 17. In case the bottom of the casing is set to the position indicated by the dotted line and the screw 36 is turned on The mass coming from the conveyor 11 is fed to an elevator 35, ending with a screw 38 in the bunker. The screw 36 with the bottom 37 and the elevator 35 can be installed differently, for example, at the beginning of the conveyor pile. When harvesting laid bread, lifters 39 are installed on the cutting unit. When selecting rolls, a pick-up with a device for spreading the roll across the entire width of the threshing drum is installed on the header.

Combine when harvesting biologically valuable grain works as follows.

The plant stems with the reel 1 strips are fed to the cutting unit 2, and then the cut mass is fed into the threshing machine, where it is threshed by drum 3 and separated through the lattice concave 4 into chamber 7. The partially threshed mass is fed to the tapering screw 5 and then conveyed to the receiving part 6 bit 14 of the second threshing drum. When the mass moves to the receiving beater, there is an additional selection of grain from the pile through the trellised bottom of the screw and conveyor. The grain sifted in such a way is poured onto the lower feeders.

The receiving beater 14 mass is sent to the threshing drum 12, which is threshed and sieved through a lattice concave 13 on a page board 17. At the exit of the threshing apparatus, the straw is directed by the breaker beater 15 to the straw walker 16, while part of the grain is sifted through the comb concave. Grains and a small pile selected on the straw walker 16 go to the finger grate and go from there to the upper louver sieve 18. Grain sifted through the upper grate and a part of the small pile go to the lower louver sieve 19. Both sieves are blown with a fan 25.

Having passed through the sieve holes 19, the grain enters the grain auger 20 and the elevator 21 is fed to the auger 30, which distributes it along the rear section of the hopper 31. When harvesting biologically valuable grain, the screws 34 do not work.

Threshers, passing through the holes of the upper sieve extension 29, with a kolosov auger 22 and an elevator 23 are fed to the screw 24, which directs them to the thresher to the threshing machine. The straw from the straw walker 16 by the straw crusher 27 and the chaff C of the extension cord 29 by the polisher 28 are fed to a stacker, discharged as it is filled. Grain and small pile, highlighted in

the chamber 7 and the conveying devices are conveyed by the conveyor 8 to the narrowing augers 9, which direct the mass to the conveyor //. When harvesting biodegradable grain, the bottom 37 is set to the position indicated by the dotted line, so the screw 36 mass coming from the conveyor // feeds to the elevator 35. The screw 38 spreads grain with the grain in the front section of the bunker. After the sections are filled, the grain and grain are discharged into vehicles by means of screws 32 and 33, respectively.

When harvesting Bcei .. grain in the form of food, i.e., with cleaning in a combine, the technological process of operation of the combine is the same as described except that in this case the grain with meat threshed in the first threshing machine is fed directly to the cleaning of the combine. For

this screw 36, the elevator 35 and the screw 38 are turned off, and the bottom 37 is set to the position indicated by the solid line. On cleaning the combine, the mass is mixed together with the mass coming after the second

threshing, and goes through the whole further cycle described above. To use the front section of the bunker to collect grain, augers 34 are included, pumping grain from the rear section to the front section.

After filling both sections, the grain is discharged into the vehicles by the screws 32 and 33.

Taking into account that when harvesting biologically valuable grain it is not harvested, but is cleaned up on current, it is possible to increase the productivity of the combine, provided that the normal load on the cleaning of the combine is maintained. Therefore, it is recommended to clean more of the first technological process.

When selecting the grain mass from the roll, the pick-up, picking up the roll, feeds it to the dispensing device, which directs it to the threshing machine. Further, the two described technological processes are carried out.
