The swing guide body of the above-mentioned known example has a configuration in which two guide portions that are slanted to the already-cut ground side are fixed to the swing sorting shelf, so that the dust on the guide portion is lower on the guide portion. There is a strong tendency to increase the amount of dust that falls from the lower end of each guide part, and the dust is discharged in a streak shape behind the lower end of the guide part. There is a problem that objects are deposited and diffusibility is low.
That is, both the gravity acting from the inclination of the guide part and the swinging by the swing sorting shelf act on the dust on the guide part. Since it acts on the dusts in the same way, it flies almost the same distance from the lower side end of each guide part rather than spreading apart and falls to the field. As a result, the field after running has a streak shape. Dust deposits accumulate on the surface.
The present application devised that "force" acts so as to move the dust on the swing guide body in various directions, so that the dust discharged from the swing sorting shelf spreads widely in the field. It is what I did.

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.

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.
The swing sorting device 21 is formed on the transfer shelf 22 with the start end (front end) of the swing sorting shelf 20 positioned above the hot casing 12. The configuration of the transfer shelf 22 is arbitrary, and the lower side in the transfer direction is inclined low, or a protrusion or an unevenness is provided on the upper surface of the transfer shelf 22 so that the granule 23 on the lower side in the transfer direction of the swing sorting device 21. What is necessary is just to be able to transfer the fallen object from the handling net 15 toward.

A dust removal processing device 30 is provided on one side (right side) behind the threshing chamber 11. The dust removal processing apparatus 30 is configured by mounting a dust removal treatment cylinder 31 substantially parallel to the axis of the handling cylinder 10. A second processing device 32 for processing the second item collected by the second conveyor 27 is provided on the front side of the dust removal processing device 30. The tip of the second reduction device 33 is opened above the start end side of the second processing cylinder 34 of the second processing device 32, and the base of the second reduction device 33 is connected to the end of the second conveyor 27. The second processing cylinder 34 is arranged concentrically with the dust removal processing cylinder 31.
A suction dust exhaust fan 35 is provided on the opposite side of the dust exhaust processing device 30. Reference numeral 36 denotes a casing of the suction dust exhaust fan 35, and 37 denotes an air exhaust port of the casing 36. A cutter device 38 is provided on the rear side of the threshing device 4. The cutter device 38 has a known configuration and is provided with a pair of cutter blades 39.

Accordingly, a swinging guide body 40 for diffusion for diffusing and discharging the discharged material is provided at the rear part of the swing sorting shelf 20. The swing guide body 40 includes a first guide portion 41 attached to the swing sorting shelf 20 and a second guide portion 42 provided continuously to the first guide portion 41.
The first guide part 41 and the second guide part 42 are configured to be inclined so as to become lower toward the rear side, and the inclination angles of the first guide part 41 and the second guide part 42 are different from each other. .
Even if the dust discharged from the rear part of the swing sorting shelf 20 is swung and diffused by the swing guide body 40 having the same inclination angle, the dust falling from the end of the swing guide body 40 is substantially the same. However, in this application, the swing guide body 40 is lowered as it reaches the rear side, and the cutting area side is lower in the present application. In addition, the first guide portion 41 and the second guide portion 42 are configured to be inclined so that the inclination angles of the first guide portion 41 and the second guide portion 42 are different from each other. .

In the embodiment, a bent line 43 is formed by bending an intermediate portion of a single plate-like swing guide body 40, and the bent line 43 is moved from the bent line 43 to the first guide portion 41. A second guide portion 42 is provided on the front side of 43, and the inclination angle of the second guide portion 42 on the front side of the bending line 43 is steeply inclined.
Therefore, the swing guide body 40 is easy to manufacture, and the first guide portion 41 and the second guide portion 42 having different inclination angles can be attached at a time, and the attachment is easy.
In this case, the first guide portion 41 inclines the base end edge 41 </ b> A of the first guide portion 41 to the right-down inclination when viewed from the rear, and guides the dust to the right as the first guide portion 41 as a whole. Since the tip end edge 41B of the first guide part 41 is inclined low with respect to the base end edge 41A, it is expected that the first guide part 41 will diffuse to the left side of the swing sorting shelf 20 by the rearward downward inclination of the first guide part 41. .

That is, the swinging guide body 40 inclines the first guide part 41 and the second guide part 42 not only in the left-right direction but also in the front-rear direction, and the first guide part 41 and the second guide part 42 Since the tilt angles of the front, rear, left and right are relatively changed, coupled with the front / rear swing of the swing sorting shelf 20, the dust discharged on the swing guide body 40 can be diffused well and widely.
Further, if the first guide portion 41 is formed in a substantially triangular shape with the apex on the rear side, the dust is quickly dropped from the end edge 41B and diffused to the left side, and the second guide portion 42 has the apex. If it is formed in a substantially triangle shape on the front side, it can be expected that dust dust falls from the tip end edge 42B of the second guide portion 42 and diffuses to the right side.
In this way, since the dust is diffused and discharged to the field, it is expected that the soil quality of the field can be improved uniformly.

Further, the swing guide body 40 fixes the first guide portion 41 to the vertical plate 45, and the vertical plate 45 is attached to the swing sorting shelf 20 by a fixture 46 such as a bolt so that the vertical position can be adjusted. When the vertical plate 45 is raised with respect to the swing sorting shelf 20, it suppresses the out-of-machine discharge of grains, and when it is lowered with respect to the swing sorting shelf 20, it promotes the discharge of dust, and the swing sorting shelf. 20 sorting loads can be reduced.
Thus, the workpieces that fall on the swing sorting shelf 20 tend to drop a lot on the tip side of the culm that is conveyed by the cereal supply / conveyance device 12, and the tip side (anti-grain supply) The dust removal processing device 30 and the second processing device 32 are provided on the transport device 12 side, and the object to be processed that has fallen on the swing sorting shelf 20 is the tip side (anti-wheat grain supply transport device 12 side). Since there are fewer objects to be processed on the swing sorting shelf 20 on the stock source side (the grain supply / conveying device 12 side) than on the anti-grain supply / conveying device 12 side, The left end portion of the tip end edge 41B of the guide portion 41 is positioned at a distance from the left end portion of the swing sorting shelf 20 on the side of the anti-wheat grain supply / conveyor 12 so that the dust is dropped from the swing sorting shelf 20. I have to.

Further, the end of the dust removal processing device 30 is closed by a non-perforated plate 50 in the left-right direction, and although not shown in the drawings, the dust removal processing device 30 is placed on the swing sorting shelf 20 from the dust discharge port formed on the end side of the dust removal processing device 30. Dust is dropped and discharged from the end of the swing sorting shelf 20.
That is, when the dust is discharged toward the rear of the dust treatment apparatus 30, the dust becomes a lump. The dust is prevented from becoming a lump and is discharged from the dust treatment apparatus 30. The grains contained in the product can be dropped and collected on the swing sorting shelf 20 and the dust can be diffused by the swing guide body 40, so that a rational configuration is obtained.

Thus, the swing guide body 40 has a rear side part thereof overlapped with a part of the fixed diffusion guide body 53 provided on the rear cover 51 below the cutter device 38 in a side view (plan view). To provide.
Therefore, dust can be joined to the cutting waste falling from the cutter device 38, and the dust can be diffused by the fixed diffusion guide body 53, so that the diffusibility is improved.
The fixed diffusion guide body 53 is formed by the first fixed diffusion portion 54 and the second fixed diffusion portion 55, and is provided so as to be inclined so as to become lower toward the right side in a rear view.

Thus, a cutting guide plate 58 is provided on the front side of the cutter device 38, and the cutting guide plate 58 has an upper portion positioned substantially at the same height as the lower portion of the upper cutter blade 39. The cutting guide plate 58 is inclined rearward so that the cutting guide plate 58 is located on the rear side as it goes downward, and the lower portion of the cutting guide plate 58 is positioned below the lower portion of the lower cutter blade 39.
The cutting guide plate 58 guides the cutting waste of the waste cut by the cutter device 38 so as to fall backward, and the swing guide body 40 is located rearward of the rear end of the cutting guide plate 58. If it is arranged so that the rear part is located, the cut waste can be diffused by the swing guide body 40, and the diffusibility can be further improved.
Note that the cutting guide plate 58 is positioned in the front-rear direction in FIG. 7 because both the rear cutting guide plate 58 and the front cutting guide plate 58 are visible.
Reference numeral 60 denotes a seal member provided on the rear plate 61 of the threshing device 4 and is formed of an elastic member. The lower end of the seal member 60 is brought close to the upper end of the vertical plate 45 at the rear of the swing sorting shelf 20, and the cutting waste falling from the cutter device 38 is returned to the strola rack 25 of the swing sorting shelf 20. It is configured such that dust on the Strollac 25 can be discharged while preventing it.

In addition, the rear lower part of the swing sorting shelf 20 is opened to form a discharge port (reference numeral omitted) for dropping the dust to the field, and the swing guide body 40 is located above the discharge port.
Further, side covers 62 are provided on the left and right sides of the rear cover 51 below the cutter device 38 (FIG. 10), surround both the left and right sides and the rear side, and the lower and front sides are opened to remove dust. And scatter and drop the sawdust.
Thus, the second guide part 42 is provided so that a part thereof protrudes to the right side of the right side plate 64 of the swing sorting shelf 20.
Accordingly, the dust discharged from the swing sorting shelf 20 can be diffused to the right side of the swing sorting shelf 20.

  That is, in the harvesting work of the combine, the left side of the traveling direction becomes the uncut ground side, and if dusted waste or cutting sawdust is applied to the uncut grain cocoon, it becomes difficult to align in the subsequent cutting work, There is not much diffusion of dust and cutting waste on the left side. Therefore, the dust discharged from the swing sorting shelf 20 and the cutting waste from the cutter device 38 are placed on the right side of the swing sorting shelf 20. By diffusing to the already cut ground, it is possible to facilitate the alignment in the next cutting operation, and further, in the next cutting operation, the dust is diffused to the right side from the swing sorting shelf 20, It is possible to expect dust scattering to the boundary between the previous uncut area and the previously cut area, and as a result, it is possible to improve the uniformity of spreading throughout the entire cut area and improve the soil quality of the field. It can also be expected to have a uniform effect.

In this case, the second guide part 42 is formed so as to protrude rightward from the bending line 43 of the swing guide body 40 and further to the right side of the right side plate 64 of the swing sorting shelf 20, and the first guide part 41. Since the tilt angle is set to be steeper, it is possible to favorably diffuse dust and cutting waste.
Further, when a part of the second guide part 42 is positioned above the first fixed diffusion part 54 and arranged so as to overlap a part of the second fixed diffusion part 55, This is preferable because the dust and cut waste are taken over by the second fixed diffusion portion 55 and diffused to the right side of the machine body by the second fixed diffusion portion 55.
In this case, the second guide portion 42 overlaps the second fixed diffusion portion 55 in a side view when the swing sorting shelf 20 swings backward, but when the swing sorting shelf 20 swings forward, the second fixed diffusion is performed. If it is configured so as not to overlap with the portion 55 in a side view, it is possible to prevent clogging of a part of dust particles, cutting dust, and the like between the second guide portion 42 and the second fixed diffusion portion 55, which is preferable. is there.

That is, part of the dust and cutting waste from the first guide part 41 of the swing guide body 40 is mainly taken over on the first fixed diffusion part 54 and diffused also by the first fixed diffusion part 54, Part of the dust discharged from the second guide portion 42 and the cut waste is mainly transferred to the second fixed diffusing portion 55 and diffused by the second fixed diffusing portion 55, so that it can be distributed to the left and right for diffusion. , Make the diffusion better.
Further, when the tilt angle of the tip end edge 42B of the second guide portion 42 and the tilt angle of the second fixed diffusing portion 55 are made substantially the same in the rear view (FIG. 10), the swing guide body 40 to the second fixed diffusing portion. The transfer to 55 becomes smooth, which is preferable.

Thus, a battery 66 is installed on the front side of the front cover 65 of the cutter device 38, and an open / close door 67 for battery maintenance is provided on the front cover 65. The open / close door 67 and the swing guide body 40 are provided as an open / close door. If the relative arrangement is made so that the swing guide body 40 is located on the right side as much as possible within a range that does not affect the opening and closing of the 66, both battery maintenance and diffusion by the swing guide body 40 can be achieved. Is preferable.
Reference numeral 68 denotes a lock device of the cutter device 38. That is, although the illustration of the cutter device 38 is omitted, the cutter device 38 is provided so as to be rotatable about the rotation fulcrum shaft provided in the body fixing portion, and the lock device 68 stops and holds the rotation of the cutter device 38.
