SU1271442A1 - Cleaning of combine for harvesting seeds which are insufficiently loose - Google Patents

Description

rfi-A j ifi, brSrj "-. 4 e. Fm

The invention relates to the agricultural machinery industry and can be used in the cleaning designs of combines for low-season seeds of desert forage plants.

The purpose of the invention is to demonstrate the reliability of operation with the nuteum to prevent clogging of the receiver of the cleaned seeds and the transporting device, as well as reducing the contamination of the seeds.

FIG. 1 shows a diagram of the combine with the proposed cleaning; on fig. 2 harvester, cross section; in fig. 3 a section A - A in FIG. 2

Combine for cleaning low-grade seeds

has a header

reel

and “floating conveyor 3, washing drum 4 with deck 5, beater bit (i, self-supporting with 7, transport board 8, as well as cleaning, the sieve part of which is made with upper 9 and lower 10 sieves Combine also has frame 11, chassis part 12 and fan 13.

On frame 11, the axis 14 is rigidly mounted. On it is installed a mechanical cleaning drum 15 mounted on the inieii and equipped with a mesh Gickshndrich surface d,: I pass through it of small light impurities. The cavity of the drum 15 is divided, 1ena per1Ch) by the rods 16 into two stationary ones: they are: first intake: jupe 17 to remove soft light impurities and to press down; to the outer cylindrical surface of the drum 15, to the second zone 18.

The partitions 16 are provided along the entire length with freely rotating slotted sealing rollers 19.

The drum 15 is installed by the ne () unit 20 of the cleaned seeds to feed the nostrums from the seed part of the seed to the outer cylindrical surface of this drum, having an OH1, and distribution blades 21.

Cleaning the combine is equipped with a receiver 22 of coarse impurities, which is located under the drum 15 at the suction zone 17. The receiver 20 of the cleared seeds is located at the node 15 by the drum 15 at the second zone 18. The receivers 20 and 22 are equipped with vacuum valves 23 and are connected to transporting devices for feeding respectively cleaned seeds and impurities into the corresponding hoppers 24 and 25.

The conveying devices of the washer are in the form of pneumatic conveyors 26 and 27 connected to the fan 13.

Combine cleaning works as follows.

Processed on the grids 9 and 10, the seed heap enters the mesh surface of the rotating drum 15. By means of the air flow of the pneumatic conveyor 27 in the suction zone 7, a vacuum is created, as a result of which seeds & , 2 are fed to the outer mesh surface of the drum 15, and the chalk 1: no impurities (leaves, whine). Through the holes of the mesh surface they are sucked into the cavity zone 17 of the barrel and transported further to the impurity bin 25 for impurities.

The space between the blades 21 holds coarse impurities (branches, parts of the roots

and so-called), and when the drum 15 rotates, these impurities of the node under the action of the force of gravity fall to the vacuum-to, 1 apan 23, which, rotating, dump them into the city of receiver 22, from where impurities of the pneumatic 11 sportsman 27 enter the bunker 25

Seeds are separated from the reticulated novverhnosT1 of the drum over the receiver 20 under the second zone 18 of the cavity of the drum 15, where, due to the lack of suction flow, the seeds fall

0 down to the corresponding vacuum valve .23, 1 stalk into the receiver 20 and further along the pneumatic adapter 26 - into the bunker 24.

Cleaning a family pile with a pneumatic drum by means of 15 reduces the contamination of seeds by 15, guarantees the reliability of the device and reduces the cost of subsequent transportation of seeds, their cleaning and drying.

Vacuum-klag any 23 provide tightness of the device elements. Blades 21

drum 15 also creates tightness.
