JP 2001-204229 A

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. Since it moves and slides down, the lump of dust falls directly from the end of the guide, and lump of lump accumulates in the form of streaks behind the lower end of the guide. Thus, there is a problem that 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 is designed so that the “force” of the exhaust air from the suction dust exhaust fan 35 acts when the dust exhaust on the swing guide body falls, so that the dust exhaust from the swing sorting shelf is removed. It is intended to diffuse widely in the field.

In the present invention, a cutting unit 5 is provided in front of the traveling device 2, and a threshing device 4 for threshing the culm conveyed by the cereal supply and transport device 12 is provided above the traveling device 2. Below the threshing chamber 11 with the handling cylinder 10 mounted on the top, a wind selection chamber 18 for wind-selection by blowing air from the tang 16 is provided, and the swing selection shelf 20 that reciprocally swings to the wind selection chamber 18 is configured. An oscillating and sorting device 21 is provided, and a suction dust exhaust fan 35 is provided on the side of the oscillating and sorting shelf 20 on the side where the cereal supply and transport device 12 is provided. A dust removal processing device 30 communicating with the threshing chamber 11 is provided on the side, and dust discharged from the swing sorting shelf 20 to the outside of the machine is sucked and discharged to the rear of the swing sorting shelf 20. The swing guide body 40 that guides toward the air outlet 37 side of the It is made into the combine characterized by providing rocking | fluctuation integrally, and it is on the rocking | shrinking selection shelf 20 on the opposite side to the grain supply and conveyance apparatus 12 compared with the grain supply and conveyance apparatus 12 side. Since there are many objects to be processed, the dust after sorting is guided to flow down toward the air exhaust port 37 side of the suction dust exhaust fan 35 by the swing guide body 40 and is put on the exhaust air from the suction dust exhaust fan 35, so that Do not drop and diffuse.
Accordingly, the swingability of the swing guide body 40 swinging integrally with the swing sorting shelf 20 and the diffusibility of diffusing dust to the left and right sides using the exhaust air from the suction dust exhaust fan 35 are improved. .
The present invention is characterized in that the edge 40B on the suction dust exhaust fan 35 side of the swing guide body 40 is disposed so as to be substantially parallel to the air exhaust direction from the air exhaust port 37 of the suction dust exhaust fan 35. The dust discharged from the rear part of the swing sorting shelf 20 is guided to flow down along the direction of the exhaust air of the suction dust exhaust fan 35 and merges with the exhaust air of the suction dust exhaust fan 35. Then, it is agitated by the exhaust air of the suction dust exhaust fan 35 and diffuses while being scattered.

According to the first aspect of the present invention, the flow direction of the dust can be changed by the swing guide body 40 at the rear of the swing sorting shelf 20 and can be efficiently diffused by being put on the exhaust air from the suction dust exhaust fan 35. .
According to the second aspect of the present invention, the diffusibility can be improved by causing the dust discharged from the rear portion of the swing sorting shelf 20 to smoothly join and diffuse the exhausted air of the suction dust exhaust fan 35.

An embodiment of the present invention will be described with reference to the drawings as an example of a combine. Reference numeral 1 denotes a combiner body frame, 2 a traveling device that travels by a pair of left and right crawlers 3, 4 a threshing device provided above the body frame 1, 5 Is a cutting part provided on the front side of the threshing device 4, 6 is a Glen tank provided on the side of the threshing device 4, and 7 is a control unit provided in front of the Glen tank 6.
The threshing device 4 is provided with a threshing chamber 11 in which a handling cylinder 10 is mounted substantially horizontally at an upper portion, and a cereal supply / conveying device 12 that supplies and conveys cereals harvested by the reaping part to one side of the threshing chamber 11. 13A and a supply transport chain 13B (FIG. 10) for holding and transporting the cereal grains are provided. 14 is a waste transporting device that transports the threshed waste that has been handed over from the cereal supply transport device 12.
For ease of understanding, the following explanation will be given for the sake of convenience, but the configuration is not limited thereby.

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, a wind selection chamber 18 capable of wind-selecting grains and foreign matters by blowing air from the red pepper 16 is formed, and in the wind selection chamber 18, in the air blowing direction (front-rear direction) of the red pepper 16. A swing sorting device 21 configured by a swing sorting shelf 20 that swings back and forth 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 portion 22 is arbitrary, and the lower side in the transfer direction is inclined low, or protrusions and irregularities are provided on the upper surface of the transfer shelf portion 22 so that the granule 23 on the lower side in the transfer direction of the swing sorting device 21 It is only necessary that the fallen object from the handling net 15 can be transferred.

The grain sieves 23 are used to sort out grains and foreign matters that have fallen from the handling net 15, and are arranged in parallel in a swinging direction at a predetermined interval. The grain sheave 23 is formed in a thin flat plate shape and is inclined so that the lower side (rear side) in the transfer direction is higher.
Accordingly, a plurality of chaff sheaves 24 are arranged in parallel on the swing sorting shelf 20 on the lower side (rear side) in the transfer direction from below the grain sheave 23. The chaff sheave 24 is attached to the swing sorting shelf 20 with an arbitrary configuration so that the inclination angle can be adjusted. A Strollac 25 is provided on the lower side of the chaff sheave 24.

A first conveyor 26 is provided below the swing sorting shelf 20, and a second conveyor 27 is provided behind the first conveyor 26.
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 in the same axial center as 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, 37 denotes an air exhaust port of the casing 36, and 37A denotes an air exhaust guide. 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 is provided so as to be inclined so as to guide the dust discharged from the swing sorting shelf 20 to be placed on the exhaust air of the suction dust exhaust fan 35.
The swing guide body 40 is lowered from the mounting portion 41 of the swing guide body 40 attached to the swing sorting shelf 20 to the rear side, and lower on the left side with respect to the right side of the swing guide body 40. Tilt down to the left.

That is, the workpieces that fall on the swing sorting shelf 20 tend to drop a lot on the tip side of the grain pods conveyed by the corn supply / conveyance device 12, and the tip side (anti-grain supply / conveyance) The apparatus 12 side) is provided with a dust removal processing apparatus 30 and a second processing apparatus 32, and a large amount of workpieces that have dropped on the swing sorting shelf 20 tend to accumulate on the anti-grain supply / conveyance apparatus 12 side. Thus, since there are few objects to be processed on the swing sorting shelf 20 on the side of the grain supply / conveyance device 12 as compared to the side of the anti-grain supply / conveyance device 12 side, the swing guide body 40 is inclined downwardly to the left. Then, once guided to the left rear side of the swing sorting shelf 20 and put on the exhausted air from the suction dust exhaust fan 35, it is diffused without falling into a lump.
Therefore, the diffusibility of diffusing dust particles to the left and right sides is improved by using the swing of the swing guide body 40 swinging with the swing sorting shelf 20 and the exhaust air from the suction dust exhaust fan 35.

In addition, since the dust is diffused and discharged to the field, it can be expected that the soil quality of the field can be improved uniformly.
Further, the rocking guide body 40 is configured so that the base end edge 41A of the mounting portion 41 is inclined downwardly to the left (see FIG. 10) when viewed from the rear side, so that dust is guided to the left as the rocking guide body 40 as a whole. It is expected that the air is exhausted from the suction dust exhaust fan 35.
Thus, the swing guide body 40 is formed in a triangular shape with the apex in the plan view rearward in order to drop and diffuse the dust from the left side, and the right end edge 40A of the swing guide body 40 stands upright. A partition 42 is provided, and a part of the upper surface of the right partition 42 at a predetermined end position is cut out to form a cut surface 43.

When the dust collected from the swing sorting shelf 20 falls on the swing guide body 40, it flows down by the tilt and swing of the swing guide body 40, hits the right partition 42, and is guided to the left by the right partition 42. However, since a part of the upper surface of the predetermined end position of the right partition 42 is notched and formed in the notch surface 43, the resistance of the right partition 42 can be lowered by the notch surface 43 to easily remove dust. Is dropped from the right partition 42 to prevent falling as a lump and diffuse. In other words, the right partition 42 is restrained from being caught by the notch surface 43 and diffused.
A central partition 44 substantially parallel to the right partition 42 is provided at a predetermined position between the left and right sides of the swing guide body 40.

The central partition body 44 guides the exhausted dust from the suction dust exhaust fan 35 to be dispersed by the central partition body 44, rather than all of the dust on the swing guide body 40 hitting the right partition body 42. .
Further, by providing the central partition 44, the rigidity of the swing guide body 40 itself is also improved.
Reference numeral 45 denotes a notch surface formed by notching a part of the upper surface of the central partition 44 at a predetermined end position.
The swing guide body 40 has a base mounting portion 41 fixed to a vertical plate 47, and the vertical plate 47 is mounted to a swing sorting shelf 20 by a fixing tool 48 such as a bolt so that the vertical position can be adjusted ( FIG. 10). When the vertical plate 47 is higher than the swing sorting shelf 20, it suppresses the out-of-machine discharge of grains, and when it is lower than the swing sorting shelf 20, it promotes the discharge of dust, and the swing sorting shelf. 20 sorting loads can be reduced.

Further, since the swing guide body 40 is attached to the swing sorting shelf 20, the swing guide body 40 swings back and forth in the air exhaust path from the air exhaust port 37 of the suction dust exhaust fan 35, and diffuses dust.
Further, the swing guide body 40 is provided behind and below the end of the dust disposal apparatus 30 in plan view.
Accordingly, the dust discharged from the dust processing apparatus 30 falls on the swing guide body 40, and the dust is placed on the wind exhaust from the suction dust exhaust fan 35, thereby improving the diffusibility.
In this case, the end of the dust treatment apparatus 30 is closed by a non-perforated plate 50 in the left-right direction (FIG. 8), and although not shown, it swings from a dust outlet formed on the end side of the dust treatment apparatus 30. When configured to drop the dust on the sorting shelf 20 and discharge it from the end of the swing sorting shelf 20, the dust from the dust disposal device 30 is once swung laterally with respect to the axial direction. The dust is discharged onto the sorting shelf 20 to prevent the dust from becoming clumps, and the grains contained in the dust discharged from the dust treatment device 30 are dropped onto the swing sorting shelf 20. In addition, the dust can be collected, and the dust discharged from the dust processing apparatus 30 can be diffused by the swing guide body 40, so that a rational configuration is obtained.

Accordingly, the swing guide body 40 is provided so that a part of the rear side thereof overlaps the fixed diffusion guide body 53 provided on the rear cover 51 below the cutter device 38 in a side view (plan view) ( 6 and 8).
Therefore, dust can be joined to the cutting waste falling from the cutter device 38, and can also be diffused by the fixed diffusion guide body 53 by being placed on the exhaust air of the suction dust exhaust fan 35, thereby improving the diffusibility. To do.
In this case, 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 to be inclined so as to become lower toward the right side in the rear view. Is positioned above the first fixed diffusion portion 54 (FIG. 10).

Therefore, part of the dust and cutting waste from the swing guide body 40 is mainly taken over on the first fixed diffusing portion 54 and diffused by the first fixed diffusing portion 54, but falls from the cutter device 38. Since the cut dust and the dust discharged on the exhausted air from the suction dust exhaust fan 35 are taken over and diffused on the second fixed diffusing portion 55, the diffusibility is further improved.
Accordingly, the left end edge 40B of the swing guide body 40 is disposed so as to be substantially parallel to the air exhaust direction from the air exhaust port 37 of the suction dust exhaust fan 35 (FIG. 10).
Accordingly, the dust that moves on the rocking guide body 40 joins the exhaust air of the suction dust exhaust fan 35 in the substantially perpendicular crossing direction and rides on the exhaust air, thereby improving the diffusibility.
That is, it is possible to suppress the resistance when the dust is joined to the exhaust and to improve the diffusibility.

Reference numeral 60 denotes a seal member provided on the rear plate 61 of the threshing device 4 (FIGS. 6 and 7), which is formed by an elastic member. The lower end of the seal member 60 is brought close to the upper end of the vertical plate 47 at the rear of the swing sorting shelf 20 so that the cutting waste falling from the cutter device 38 returns onto the swing sorting shelf 20 (Strolack 25). It is configured so that dusts on the Strollac 25 can be discharged while preventing the above.
In addition, since the seal member 60 hangs down, it is also expected to have an effect of preventing the cutting rods and dust discharged from the rocking guide body 40 from returning to the rocking sorting shelf 20.
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, a cutting guide plate 65 is provided on the front side of the cutter device 38 (FIGS. 6 and 7), and the cutting guide plate 65 is positioned at the same height as the lower portion of the upper cutter blade 39 so that the cutting guide The guide plate 65 is inclined rearward so that the guide plate 65 is located on the rear side as it goes downward, and the lower portion of the cutting guide plate 65 is below the lower portion of the lower cutter blade 39 and the upper and lower cutter blades 39 overlap. It is located behind the lower part of the part.

The cutting guide plate 65 guides the cut cutting waste of the waste cut by the cutter device 38 so as to fall backward, and the swing guide body is located behind the rear end of the cutting guide plate 65. If it is arranged so that the rear part of 40 is located, the cut waste can be diffused by the swing guide body 40, and the diffusibility can be further improved.
That is, it can be expected that mixing dust and cutting sawdust will further improve the soil quality of the field.
Note that the cutting guide plate 65 is located in the front-rear direction in FIG. 7 because the cutting guide plate 65 on the back side and the cutting guide plate 65 on the near side are visible.

Accordingly, the swing guide body 40 is provided in the upper and lower middle of the exhaust air passage of the exhaust air outlet 37 of the suction dust exhaust fan 35.
That is, the air exhaust port 37 is formed to have a predetermined width in the vertical direction, and the swing guide body 40 is positioned in the middle of the air exhaust port 37 in the side view.
Therefore, since the dust discharged before dropping from the swinging guide body 40 also receives the air exhaust from the suction dust exhaust fan 35, the diffusibility can be improved.
In this case, when the swing guide body 40 swings rearward of the swing sorting shelf 20 and overlaps the fixed diffusion guide body 53 in a side view, the lower surface of the swing guide body 40 and the upper surface of the fixed diffusion guide body 53 It is configured to have a predetermined interval in between (FIG. 7) to prevent clogging of part of the dust and cutting waste.

  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.

(Operation of Example)
When the vehicle is caused to travel by the traveling device 2, the ear of the cereal harvested by the cutting unit 5 is supplied to the threshing chamber 11 of the threshing device 4 and threshed.
The threshed material to be processed falls on the swing sorting shelf 20 and is sorted by blowing air from the red pepper 16 and swinging the swing sorting shelf 20, and the grains are placed on the first conveyor 26 below the swing sorting shelf 20. Collected and collected outside the machine.
The second item collected on the second conveyor 27 below the swing sorting shelf 20 is reduced by the second reduction device 33 to the upper side of the second end of the second processing cylinder 34 of the second processing device 32 and processed. The grains are returned to the starting end of the swing sorting shelf 20 and sorted by the swing sorting shelf 20 together with the cereals threshed in the threshing chamber 11.

In addition, an object to be processed that is threshed in the threshing chamber 11 and does not fall from the handling net 15 is agitated by the dust treatment cylinder 31 in the dust treatment apparatus 30, and the grains are swung from the treatment net (not shown). It falls on 20 and is sorted.
In addition, since the suction dust exhaust fan 35 is provided so as to face the dust exhaust processing device 30, dust and soot discharged from the dust exhaust processing device 30 are suctioned and removed by the suction dust exhaust fan 35. .

Accordingly, the swing guide body 40 is tilted at the rear of the swing sorting shelf 20 so as to guide the dust discharged from the swing sorting shelf 20 to be placed on the exhaust air of the suction dust exhaust fan 35. Therefore, the dust discharged from the rear portion of the swing sorting shelf 20 is spread on the field while being diffused by the swing of the swing guide body 40 and the exhaust air from the suction dust exhaust fan 35.
That is, although dust or the like may be clumped on the swing sorting shelf 20, it is swung on the swing guide body 40, and it is put on the exhaust air from the suction dust exhaust fan 35. Sawdust and the like can be dropped while diffusing.

Therefore, using the swing of the swing guide body 40 swinging with the swing sorting shelf 20 and the exhaust air from the suction dust exhaust fan 35, the dust is diffused in the left and right sides of the swing sorting shelf 20. To improve diffusibility.
Therefore, since the dust collection apparatus 30 and the suction dust collection fan 35 are opposed to each other and the swing sorting shelf 20 is positioned in the middle, the dust collection material is diffused, which is a rational configuration.
In this case, in the harvesting operation of the combine, if the left side in the traveling direction (the side of the grain supply / conveying device 12) is the uncut area side and dust or cut chips are applied to the uncut grain, the subsequent cutting Since it becomes difficult to align the work, it is not desirable to diffuse dust and cutting waste on the left side. However, in this respect as well, the swing guide body 40 sucks the dust while guiding the dust to the left side. Since dust is exhausted to the right side by the exhaust air from the dust exhaust fan 35, the dust exhausted from the swing sorting shelf 20 and the cutting waste from the cutter device 38 are further improved in diffusibility and the entire already-cut area. To diffuse.
