Further, if the scraping contact portion 41 of the front diffusion moving member 40 is provided with a scraping plate portion 43 that slides on the upper surface of the fin 37, the fin 37 of the front sheave 26 is reciprocated by the reciprocating swing of the front diffusion moving member 40. The object to be processed adhered to the surface is floated and stirred by the scraping plate portion 43, and the object to be processed on the front sheave 26 is diffused to further improve the diffusion performance.
Although the configuration of the shape of the scraping plate portion 43 is arbitrary, the scraper plate portion 43 is configured to be in contact with the workpiece on the fin 37 obliquely.
That is, the rear end portion of the scattering moving member 40 is disposed so as to face the front end portion of the rear sheave 27, and at least the left side surface of the sliding contact portion 41 with the fin 37 of the front diffusion moving member 40 is arranged on the side surface. A scraping plate portion 43 projecting in the direction, and the scraping plate portion 43 has an upper inclined surface 44 that is highest on the sliding contact portion 41 side in a front view and lower on the left side, and has a widest front side in a plan view.

A vertical attachment shaft 48 is attached to any one of a plurality of sliding contact portions 41 connected to each other of the front diffusion moving member 40, and the attachment shaft 48 is formed by a long hole at the tip of the front / rear arm 49 in the front / rear direction. Engage with the engagement hole 50. The left and right intermediate portions of the left and right arms 51 in the left and right direction are fixed to the base portion of the front and rear arms 49, and the drive link member 52 that drives the sliding contact portion 41 by the front and rear arms 49 and the left and right arms 51 is configured. The drive link member 52 rotatably attaches the left and right intermediate portions of the left and right arms 51 to a predetermined portion on the frame body 38 side by the attachment shaft 53.
A pair of drive transmission means 55 such as a wire is connected to the left and right ends of the left and right arms 51, respectively, and when one of the pair of drive transmission means 55 is pulled by a drive means (not shown) such as a motor, a pair of drives The other drive transmission means 55 of the transmission means 55 is connected to the drive means so as to be loosened.

In other words, the drive means is configured to rotate forward and backward when driven by a predetermined amount, and pulls the pair of drive transmission means 55 alternately, thereby moving the front diffusion moving member 40 back and forth.
The front sheave 26 provided with the front diffusion moving member 40 is provided on the swing sorting shelf 20 on the start end side from the air blowing port 58 of the Karatsu casing 17.
Therefore, even if the front sheave 26 is provided in the non-operation area where the sorting wind from the tang 16 does not act, the sorting efficiency can be sufficiently secured by diffusing the object to be processed by the front diffusion moving member 40, As a result, the front sheave 26 is arranged on the swing sorting shelf 20 on the start end side from the air blowing port 58 of the tang casing 17 so that the working area of the front sheave 26 can be expanded to improve the entire sorting efficiency.
Thus, the suction port 59 of the casing 34 of the suction dust exhaust fan 33 is provided on the rear left side with respect to the forward / backward swing direction of the swing sorting shelf 20, and a plurality of front diffusions arranged in parallel in the left / right direction.

It is possible to improve the grain collection efficiency by diffusion and improve the suction efficiency of the waste dust of the suction dust exhaust fan 33 by the guide body 60.
Of the front sheave 26 and the rear sheave 27 of the sheave 23, the rear sheave 27 is swing-sorted by tilting the suction port 59 side of the casing 34 of the suction dust exhaust fan 33 so as to be lower in the rear view. It attaches to the shelf 20 (FIG. 9).
Therefore, the suction efficiency of the soot dust of the suction dust exhaust fan 33 can be improved, and the whole sorting efficiency can be improved.

In other words, the object to be processed which has been meandered by the front diffusion moving member 40 of the front sheave 26 and reaches the rear sheave 27 is added with the object to be processed by the dust removal processing device 35, and the dust processing apparatus. Although the amount of work to be processed on the swing side sorting shelf 20 on the 35 side increases, the rear sheave 27 is inclined to the suction port 59 side of the suction dust exhaust fan 33 so that it is compatible with the front diffusion moving member 40. Thus, the overall sorting efficiency can be improved.
2, 5, and 10, among the front sheave 26 and the rear sheave 27 of the sheave 23, the front sheave 26 is provided with a front diffusion moving member 40 so that the inclination angle of the fins 37 of the rear sheave 27 can be adjusted. doing.

The operating arm 65 is attached to the operating shaft 64 that protrudes outward from the side plate 69 of the swing sorting shelf 20. 66 is an operation transmission member (wire), and 67 is a spring.
Each of the front sheave 26 and the rear sheave 27 is provided on the frame body 38 and is configured to be detachable from the swing sorting shelf 20 together with the frame body 38.
Therefore, the rear sheave 27 is detachable together with the tilt angle adjusting mechanism.
In this case, the operating arm 65 of the tilt angle adjusting mechanism of the fin 37 of the rear sheave 27 is mounted on the mounting shaft 63A arranged coaxially with the shaft 63 of the fin 37, and the rotational center of the operating arm 65 and the fin 37 is concentric. And

Therefore, the configuration of the tilt angle adjusting mechanism of the rear sheave 27 is simplified.

An inclined guide portion 71 that overlaps the inclined surface 70 from above is provided.
Therefore, the left and right widths of the fins 37 and the frame 38 are slightly narrower than the left and right widths of the side plates 69 of the swing sorting shelf 20 to facilitate attachment to the swing sorting shelf 20, and the tilt of the swing sorting shelf 20 is inclined. The surface 70 and the inclined guide part 71 of the frame body 38 prevent the leakage of the grain and does not lower the recovery efficiency.
13 and 14 show another embodiment of the sheave 23. A front diffusion moving member 40 and a rear diffusion moving member 61 are provided on the front sheave 26 and the rear sheave 27 of the sheave 23, respectively. The front diffusion moving member 40 and the rear diffusion moving member 61 are configured to reciprocate in opposite directions by a single driving means.

Therefore, the workpieces on the swing sorting shelf 20 meander in the opposite directions by the front diffusion moving member 40 and the rear diffusion moving member 61 of the front sheave 26 and the rear sheave 27 of the sheave 23, respectively. By moving backward, the sorting time can be lengthened to improve the grain collection efficiency, and the overall sorting efficiency by the swing sorting shelf 20 can be improved.
The rear diffusion moving member 61 has the same configuration as the front diffusion moving member 40, and includes a front and rear arm 49, a left and right arm 51, and a pair of drive transmission means 55 such as a wire at both left and right ends of the left and right arm 51. When each of them is connected and one of the pair of drive transmission means 55 is pulled by a drive means such as a motor, the other drive transmission means 55 of the pair of drive transmission means 55 is connected to the drive means so as to be loosened.
In this case, the left and right arms 51 of the front diffusion moving member 40 and the left and right arms 51 of the rear diffusion moving member 61 are connected by a pair of rear drive transmission means 55A.
The rear drive transmission means 55A are provided so as to cross each other and reciprocate left and right in opposite directions.

Accordingly, the front-side diffusion moving member 40 and the rear-side diffusion moving member 61 are reciprocated in the opposite direction at the same speed to diffuse the object to be processed by one driving means.
In addition, a guide body 60 is provided above each of the front diffusion moving members 40 and the rear diffusion moving members 61.
Therefore, the workpieces on the swing sorting shelf 20 are meandered and moved backward by the front diffusion moving member 40 and the rear diffusion moving member 61 to increase the sorting time and improve the grain recovery efficiency. At the same time, the object to be processed is brought close to the suction dust exhaust fan 33 side by the guide body 60 on the front diffusion moving member 40 of each of the front sheave 26 and the rear sheave 27, and the dust is sucked by the suction dust exhaust fan 33. And the grain separation can be promoted, and the overall sorting efficiency can be improved.
