An embodiment of the present invention will be described with reference to the drawings by using an example of a combine. Reference numeral 1 denotes a threshing apparatus. The threshing apparatus 1 is provided with a threshing chamber 11 in which a handling cylinder 10 is mounted substantially horizontally.
A lower side of the handling cylinder 10 is surrounded by a handling net 15, and a tang casing 16 of a tang 16 is provided below the handling net 15. Below the threshing chamber 11 is formed a wind selection chamber 18 capable of wind-selecting grains and foreign matters by blowing air from the red pepper 16, and reciprocates in the wind selection chamber 18 in the air blowing direction (front-rear direction) of the red pepper 16. A swing sorting device 21 constituted by a swing sorting shelf 20 that swings is provided.
In addition, in order to make an understanding easy, although it showed and demonstrated the direction for convenience, the structure is not limited by these.

The swing sorting device 21 is formed in the transfer shelf 22 that receives the object to be processed from the threshing chamber 11 with the start end (front end) of the swing sorting shelf 20 positioned above the Karatsu casing 12. The configuration of the transfer shelf 22 is arbitrary, and the lower side in the transfer direction is inclined low, or the upper surface of the transfer shelf 22 is provided with protrusions and irregularities so that the sieve ( What is necessary is just to be able to transfer fallen objects from the handling net 15 toward the (glen sieve) 23.
The sheave 23 has a front sheave 26 provided on the upper side of the threshing chamber 11 from substantially below the shed 25 and a rear sheave 27 provided on the lower side of the shed 25.
Reference numeral 30 denotes a stroller provided on the lower side of the rear sheave 27, and 31 denotes a sorting net provided below the sheave 23. 32 is a first conveyor provided at a predetermined position below the swing sorting shelf 20, 33 is a second conveyor provided on the rear side of the first conveyor 32, and 34 is a suction dust discharge fan.

Thus, the swing sorting shelf 20 includes the swing sorting shelf 20 itself, the transfer shelf 22, the sheave 23, the first sheave guide plate 40 below the front sheave 26 of the sheave 23, and the rear sheave 27. The second flow guide plate 41, the Strollac 30 and the sorting net 31 are made of a synthetic resin material, and the top surface of the sheave plate 26A of the front sheave 26 of the sheave 23 falls from the threshing chamber 11 to be processed. A gathering plate 43 for leveling the object in the left-right direction is provided. The close-up plate 43 is formed of a vertical plate that rises upward, and the start end side is positioned on the right side, and is inclined in plan view so as to become the left side as it reaches the end side. The lower plate 43 is formed of a synthetic resin material so that the lower portion thereof is integrally formed with the upper portion of a part or all of the sheave plate 26A of the front sheave 26.
Therefore, the closing plate 43 is also used as a connecting member that connects the plurality of sheave plates 26 </ b> A of the front sheave 26.

Therefore, each sheave plate 26A of the front sheave 26 is made of a synthetic resin and is made to act as a strength member with the closing plate 43, thereby reducing the weight.
The front sheave 26 and the rack portion 44 provided on the rear side of the front sheave 26 are connected by the approach plate 43. The rack portion 44 is configured by arranging fin bodies 46 in parallel in the left-right direction on the upper surface side of the plate member 45 in the left-right direction, and the plate member 45 and a part or all of the sheave plate 26 </ b> A of the front sheave 26 are connected by the approach plate 43. Link.
Therefore, since the front sheave 26 and the rack portion 44 are connected by the approach plate 43, the strength can be improved.
On the upper surface of the transfer shelf portion 22 of the swing sorting shelf 20, a front side plate 50 is provided to equalize the workpieces dropped from the threshing chamber 11 in the left-right direction. The front side plate 50 is formed of a vertical plate that stands up like the side plate 43, and the start side is positioned on the right side, and is inclined in plan view so as to become the left side as it reaches the end side. The lower side of the front side plate 50 is formed integrally with the transfer shelf 22 by a synthetic resin material.

Therefore, the front side plate 50 can improve the sorting performance by leveling the workpieces dropped from the threshing chamber 11 onto the transfer shelf 22 in the left-right direction.
The front side plate 50 and the side plate 43 are arranged so as to be shifted left and right in a plan view so as not to be linear.
Therefore, the movement of the workpiece is smoothed.
Thus, the swing sorting shelf 20 includes a main body unit 51 having a transfer shelf portion 22, a first flow guide plate 40, and a second flow guide plate 41, the rear sheave 27, the Strollac 30, and the sorting net. The inner unit 52 formed integrally with the first sheave 31 is detachably attached, and the first sheave unit 53 formed integrally with the front sheave 26 and the rack portion 44 is detachably attached to the inner unit 52.
That is, the main body unit 51 and the sheave 23 in which the first flow down guide plate 40 that guides the grain to the first conveyor 32 below the swing sorting shelf 20 is integrally formed with the outer side frame 63 of the swing sorting shelf 20. And the inner unit 52 having the sorting net 31 are configured separately, and the sorting net 31 and a part of the most downstream guide plate 40 overlap in plan view with the inner unit 52 attached to the main unit 51. Configure as follows.

Therefore, the main body unit 51 of the swing sorting shelf 20 is left on the machine body side, and the inner unit 52 and the first sheave unit 53 are integrally detached from the main body unit 51.
Therefore, the first conveyor 32 and the second conveyor 33 can be visually recognized without removing the entire swing sorting shelf 20 and the maintainability can be improved.
Further, the first sheave unit 53 is configured such that the front sheave 26 and the rack portion 44 are integrally formed through left and right side frames (inner side frames) 55 of the first sheave unit 53.
That is, the left and right ends of the front sheave 26 and the plate member 45 of the rack portion 44 are integrally connected to the left and right inner side frames 55 of the first sheave unit 53.
Therefore, the front sheave 26 and the rack portion 44 of the first sheave unit 53 can be easily formed integrally with a synthetic resin material.

The first sheave unit 53 attaches a predetermined rear portion of the inner side frame 55 to a side frame (intermediate side frame) 56 of the inner unit 52 by a rear mounting shaft 57 (FIG. 11), and attaches a predetermined predetermined portion of the inner side frame 55 to the front side. The front sheave unit 53 is attached to the intermediate side frame 56 of the inner unit 52 by a front attachment shaft 58 so that the front side portion of the first sheave unit 53 can be vertically changed (switched), and the inclination angle of the front sheave 26 can be changed.
