Description

  The present invention relates to a threshing apparatus having a handling drum.

Conventionally, in order to reduce the burden of production work, tooth handling teeth were erected in the front-rear direction on the support members fixed to the front end part, middle part, and rear end part of the handle cylinder shaft extending in the front-rear direction of the machine body. There has been proposed a threshing apparatus having a handling cylinder on which a crosspiece member is installed (see Patent Document 1).
In addition, a crosspiece member in which teeth are erected in the front-rear direction at the apex of a substantially hexagonal support member fixed to the front end part, the intermediate part, and the rear end part of the handle cylinder shaft extending in the front-rear direction of the machine body. A threshing device has been proposed that has a handling cylinder that is constructed and closed with a shielding plate in a gap between crosspiece members adjacent in the circumferential direction (see Patent Document 2).

Japanese Patent Laid-Open No. 11-28019 JP 2011-182654 A

However, in the configuration disclosed in Patent Document 1, the harvested long culm is entangled with the tooth handling erected at the rear of the barrel and the discharge performance is lowered, and the colander is entangled with the crosspiece member. Therefore, there is a possibility that the degranulation performance is lowered.
Further, in the handling cylinder disclosed in Patent Document 2, when a large amount of cereal is supplied to the front part of the handling cylinder, the support members are arranged at the front end part, the intermediate part, and the rear end part. There was a possibility that the shielding plate at the front part of the barrel would be deformed by the reaction force received from the cereal and reduce the degranulation performance and the backward conveyance performance.

  Therefore, the main problem of the present invention is to eliminate such problems, and the next problem is to propose a combine threshing device that can be easily maintained and inspected.

An oscillating sorting device 21 is provided at the upper part of the sorting chamber 20, and a potato 25 that blows air to the oscillating sorting device 21 at the lower part of the sorting chamber 20 and the grains that leak from the oscillating sorting device 21 are collected. A No. 1 receiving rod 28 and a No. 2 receiving rod 29 for collecting the grains to which the branch raft leaking from the swing sorting device 21 is attached are provided from the front side toward the rear side. The grain recovered by the first receiving rod 28 is transferred to the glen tank 5, and the grain recovered by the second receiving rod 29 is transferred to the front portion of the handling cylinder 11 and then again the handling cylinder 11. Is threshed by.

  The swing sorting device 21 includes a transfer shelf 22 disposed on the upper side of the tongue 25, a sheave 23 disposed on the downstream side of the transfer shelf 22, and a Strollac 24 disposed on the downstream side of the sheave 23. It is configured.

  The transfer shelf 22 only needs to be able to transfer the grains leaking from the handling chamber 10 to the sheave 23 disposed on the downstream side, and the rear portion of the transfer shelf 22 is inclined downward and the upper surface of the transfer shelf 22 has protrusions and irregularities. Can be provided.

  The sheave 23 is a sieve that sorts the grains transferred from the transfer shelf 22 or the grains directly leaking from the handling chamber 10 and foreign matters such as sawdust, and is a thin plate body inclined so that the downstream side becomes higher A plurality of fixed sheave members are arranged in parallel at a predetermined interval in the swinging direction of the swing sorting device 21.

  The Strollac 24 is a sieve that sifts and selects grains and the like to which branch rafts or the like are attached from relatively large swarf that has not leaked from the sheave 23.

  The air outlet of the tang 25 is divided into an upper air passage 26A and a lower air passage 26B by an air blow 27. In addition, a spiral conveyor type first spiral shaft 28 </ b> A communicating with the Glen tank 5 is arranged inside the first receiving rod 28, and the second receiving rod 29 communicates with the front portion of the handling cylinder 11. A spiral conveyor type second spiral shaft 29A is arranged.

(Cutting room)
On the rear side of the sorting chamber 20, a spreader-type cutting processing chamber 50 that cuts waste discharged from the handling chamber 10, straw waste discharged from the sorting chamber 20, and the like is provided. The cutting processing chamber 50 includes a rotary blade 51 that cuts the waste discharged from the handling chamber 10 at the front middle in the vertical direction, a receiving blade 52 that can stand and fall at the lower front portion, and a receiving blade. A front and rear sides of 52 are provided with a waste guide 53 for preventing the stay of waste or the like.

(Discharge chamber)
On the rear side of the cutting processing chamber 50, the waste that has been cut by standing the receiving blade 52 in the cutting processing chamber 50 and the waste that has not been cut by falling down the receiving blade 52 are diffused to the outside and discharged. A discharge chamber 70 is provided. The discharge chamber 70 includes a front discharge chamber 71 on which a diffusion guide 73 for diffusing waste discharged from the cutting processing chamber 50 is mounted, and a rear discharge chamber 72 mounted on the rear portion of the front discharge chamber 71. Has been.

  INDUSTRIAL APPLICABILITY The present invention can be used for a cutting processing chamber of a general combine harvester.
