[0007] At a predetermined position of the bottom plate 15 of the transport elevator 10, there is provided a cutout portion 16 for dropping unnecessary substances such as mud other than grains. That is, when the culm length of soybeans and red beans is low and the mud enters the table 9, unnecessary materials such as mud other than grains are removed by the punching section 16 before reaching the threshing room. I do. The perforated portion 16 is formed by a non-perforated plate member with a predetermined gap 19 below a perforated plate portion 18 formed by a plate member having a perforated hole 17 smaller than the grain size (particle diameter). A frame 21 integrally formed with a non-perforated plate portion 20 is formed in an opening 2 provided in the bottom plate 15.

Is fixed to the transport elevator 10 by fastening members 26 such as bolts. Therefore, just pulling out the frame 21 and inverting it,
The perforated plate portion 18 and the non-perforated plate portion 20 can be selectively used, which eliminates the need for a separate operation and place for storing rice, wheat and the like.

[0008] In addition, if a fastening tool 26 called a knob bolt that can be attached and detached without using a tool is used, the work is facilitated. Thus, the opening 16 may be provided in a part or the whole of the bottom plate 15, and the configuration thereof is arbitrary. The opening 22 may be formed in a part or the whole of the bottom plate 15 in the conveying direction. May be provided at a plurality of locations at predetermined intervals. In this case, the frame 21 is provided all below the opening 22 formed in the bottom plate 15, but the frame 21 may be formed integrally or divided, and when divided, the frame 21 on the lower side in the transport direction is formed.
The open portion 23 of the upper frame 21 is brought into close contact with the upper open portion 23 of the frame 21 on the upper side so that all the unnecessary objects fall from the open portion 23 of the frame 21 on the upper side (lower side). Is prevented, which is preferable. Therefore, by doing so, the mission 27 near the lower part of the transport elevator 10
It is preferable that the area of the opening 16 can be increased while avoiding the influence on the above-mentioned factors, and the effect is enhanced. That is, the opening 16
The waste does not fall over the entire length of the
Since it falls from the open portion 23 of the threshing device, scattering of dust is prevented as much as possible, the control section 4 is arranged on one side of the front side of the threshing device 3, the transport elevator 10 is arranged on the other side, and the front side of the threshing device 3 and the In the space surrounded by the side of the control unit 4, the crawler 24 is positioned below the control unit 4 and the transport elevator 10 to stabilize the running, and the mission is located near the lower part of the transport elevator 10 on the front side of the threshing device 3. Even if the 27 is arranged, the perforated plate portion 18 can be provided as wide as possible without giving any influence of dust, effectively utilizing the space, and not interfering with the threshing device 3. Arrangement.

The top plate 28 of the transport elevator 10 is provided with an upper opening (not shown), and the top plate 28 is provided with an inspection hatch 29 for opening and closing the upper opening, and the inspection hatch 29 is opened. At the time, a predetermined angle of repose is configured to be maintained. The configuration of the angle of repose holding means is arbitrary,
When the inspection hatch 29 is opened, the inspection hatch 29 may be brought into contact with an arbitrary fixed portion such as the reaper 5 to be supported.
May be held by a fixture (a hinge or the like, not shown) that opens and closes. Reference numeral 29a is a fixing member for fixing the inspection hatch 29, and is fixed so that the inspection hatch 29 is not opened during a normal operation. Then
A dust discharge device 30 is provided at a predetermined position of the top plate 28.
The dust discharging device 30 is provided with a dust discharging hood 32 in a dust discharging opening 31 of a top plate 28, a dust discharging fan 33 is provided in the dust discharging hood 32, and the dust discharging fan 33 discharges air to the counter control section 4 side. At the same time, the axis of the exhaust fan 33 is provided in a direction crossing the transport direction of the transport elevator 10 in plan view. That is, since the axial direction of the dust discharge fan 33 is set to the horizontal direction when viewed from the front, the dust is efficiently discharged to the side as compared with the case of the vertical direction, the discharge efficiency is improved, and the dust around the machine body is improved. To prevent scattering. The dust discharge fan 33 has a fan rotation shaft 34 mounted on the dust discharge hood 32 and a fan rotation shaft 3.
The rotation transmission path to be transmitted to the transport elevator 4 is arbitrary, but the rotation of the transport elevator 10 is transmitted, the transport speed of the transport body 35 of the transport elevator 10 is synchronized with the travel speed of the machine, and the high-speed travel is performed. In this case, the rotation speed is high, the speed is low when the vehicle is traveling at low speed, and the rotation speed is low at a predetermined speed. If the rotation is lower than a predetermined speed, the rotation is also transmitted. .
In the embodiment, the rotation of the engine is controlled by a hydraulic continuously variable transmission (H
ST), the rotation of the hydraulic continuously variable transmission is transmitted to the traveling device 2 and the transport elevator 10, and the traveling speed and the transport speed are synchronized (FIG. 1).
3 to 15).

FIGS. 16 and 17 show the dust discharging device 30.
In this embodiment, a cross flow fan 36 is provided above the dust discharge opening 31 to improve the dust discharge efficiency. That is,
By suctioning in the cross direction with respect to the rotating shaft 34 of the cross flow fan 36, the opening area of the dust discharging opening 31 is increased, and the dust discharging efficiency is improved. 37 is a dust hood 32
The casing 38 surrounding the side of the cross flow fan 36 provided in the above is a dust outlet. Also, FIG.
0 is another embodiment, and the top plate 2 of the transport elevator 10 is used.
In the case where the intermediate portion 8 in the transport direction has a high triangular shape in side view, the dust discharging device 30 is provided on the top portion 39. In this case, although an axial flow type propeller type fan is shown in the drawing, the configuration of the dust discharge device 30 is arbitrary. In addition, by arranging the dust discharging device 30 and the above-mentioned opening portion 16 in parallel, an effect of reducing clogging of the opening hole 17 with dust is expected. Thus, a work lamp 41 is provided on the upper surface of the side plate 40 on the operation section 4 side of the table 9. Work light 4
Reference numeral 1 denotes a side view, which is located behind the cutting blade 7 and in front of the auger 8, so that the working state can be easily viewed. A transport cover 42 is provided on the upper surface of the side plate 40.
Is provided. The transport cover 42 is erected by the plate-like member so as to be higher as it reaches the end portion. The start end of the transport cover 42 faces the end of the weeding body 43 provided at the front end of the side plate 40. The part is the work light 41
Is formed in the protruding cover portion 44 located above the work lamp 41 by notching the portion.

Thus, the rear wall 4 of the table 9 of the reaper 5
The second cutting blade 46 is provided behind the fifth cutting blade. The second cutting blade 46,
Reel blades 47 arranged side by side in the circumferential direction are axially mounted on a pair of left and right arms 48, and the base of the arm 48 is rotatably attached to a fixed portion. In the embodiment, the base of the arm 48 is attached to the table 9 so as to be driven by transmitting rotation from the transport elevator 10. The reel blade 47 has a base formed by a pair of left and right floating rotors 50.
The floating rotating body 50 is fixed to a rotating cylinder 52, and the rotating cylinder 52 is rotatably loosely fitted on a rotating shaft 53, and the floating rotating body 50 has a fitting groove which is long in the rotation direction. 5
4, a fitting body 55 having a smaller width than the fitting groove 54 is fitted into the fitting groove 54, the fitting body 55 is fixed to the rotating shaft 53, and the reel blade is provided between the fitting body 55 and the fitting groove 54. A spring 56 for urging the rotating shaft 53 in a direction opposite to the rotating shaft 53 is provided. A shaft 57 at an intermediate portion of the reel blade 47 is movably mounted on a long hole 59 of a rotating body 58 fixed to the rotating shaft 53. When the reel blade 47 is rotating normally, the fitting body 55 is located on the rear side in the rotation direction of the fitting groove 54 due to the elastic force of the spring 56, and when a load greater than the spring 56 is applied, the spring 56 contracts and the rotating shaft 53 Is changed so that the idle rotor 50 rotates with a delay with respect to the rotor 58 fixed to the reel blade 4.
The tip of 7 is first moved with respect to the base to be inclined, and is configured to come into contact with the cereal stem at an acute angle. That is, by inclining the reel blade 47, the contact resistance with the grain culm is reduced, thereby reducing the cutting resistance. In the embodiment, the fitting grooves 54 are arranged in a cross shape, and each fitting groove 5
The fitting body 55 is also formed in a cross shape so that the fitting body 55 is fitted to the fitting 4, so that rotation is reliably transmitted.

Next, the operation will be described. When the engine is started and the aircraft is driven by the traveling device 2, the reel 6 rotates, scrapes the uncut culm, cuts the crushed grain culm with the cutting blade 7, and rotates the auged grain culm 8. The transport elevator 10 transports the grain culm to the threshing room and supplies it. The transport elevator 1
At a predetermined position of the bottom plate 15 having a perforated portion 18 having a perforated plate portion 18, unnecessary materials such as grains and mud conveyed to the perforated plate portion 18 are unnecessary. Plate part 1
The grains fall from the perforated holes 17 of 8, and the grains are sorted out from unnecessary matters and supplied to a threshing apparatus, so that threshing and sorting can be easily performed. In this case, the perforated plate 16 is provided with a predetermined gap 19 below a perforated plate 18 formed by a plate member having perforated holes 17 smaller than the grain size (particle diameter). Since the frame 21 integrally formed with the non-perforated plate portion 20 formed of a member is provided below the opening 22 provided in the bottom plate 15 so as to be detachable and reversible, the frame 21 is porous in the case of soybean. The plate portion 18 is mounted on the transport elevator 10 so that unnecessary objects are dropped from the hole 17. In the case of rice, wheat, buckwheat, etc., the opening portion 22 is closed by the non-perforated plate portion 20. I do. Therefore, the perforated plate portion 18 and the non-perforated plate portion 20 can be selectively used only by attaching and detaching the frame body 21 and inverting it. Although the perforated plate portion 20 is not required, the work and place separately stored at this time are not required.

Further, since the front and rear sides (in the direction parallel to the transport direction) of the frame 21 are formed in the open portions 23, the waste dropped from the perforated plate 18 is solid to the lower end of the frame 21. It flows down on the inner surface (back surface) of the plate portion 20 to prevent unnecessary substances such as dust from scattering around. Then, the opening 16
Are formed continuously or at predetermined intervals in a part or the entirety of the bottom plate 15 in the transport direction, and each of the openings 22
The frame 21 is provided entirely below the frame 21. However, the frame 21 may be formed integrally or separately. In the case where the frame 21 is formed in a divided manner, the opening 23 of the frame 21 on the lower side in the transport direction becomes the same as the frame 21 on the upper side. It is preferable that all the unnecessary objects fall from the open portion 23 of the frame 21 on the upper side by closely contacting the upper open portion 23 because scattering of dust and the like is prevented. Therefore, in this way, the area of the cutout portion 16 can be increased while avoiding the influence on the mission 27 and the like near the lower part of the transport elevator 10, and the effect is enhanced, which is preferable. Then
The opening 16 is provided with a pair of front and rear and left and right support portions 24 on the lower surface of the bottom plate 15, and the frame 21 is inserted between the support portions 24 so as to be freely inserted and removed, and provided on the side of the frame 21 on the side of the anti-steering unit 4. Since the mounting plate portion 25 is configured to be fixed to the transport elevator 10 by fasteners 26 such as bolts, the fasteners 26 are simply removed, the frame body 21 is temporarily pulled out, inverted, and then inserted again. Only in response to work switching, switching work becomes very easy. The top plate 28 of the transport elevator 10 is provided with an upper opening (not shown), and the top plate 28 is provided with an inspection hatch 29 for opening and closing the upper opening. Since it is configured to hold the corners, the grain stalk is placed on the inspection hatch 29 to facilitate the operation of loading into the transport elevator 10 from the upper opening, and the remaining particles are thrown from the inspection hatch 29, so that the remaining grains are reduced. Does not occur.

That is, conventionally, a detachable lid is provided at the upper opening of the top plate 28. However, it is difficult to directly put grain stalks into the transport elevator 10 from the opening, and there is a fear that grains may be scattered. There is also a safety problem because the transport body is moving inside the transport elevator 10, but these problems are solved by holding the top plate 28 at the angle of repose. Thus, a dust discharge opening 31 is provided at a predetermined position of the top plate 28, and a dust hood 32 is provided in the dust discharge opening 31 toward the counter-control unit 4 side. In addition, since the exhaust device 30 is configured to exhaust air to the anti-steering unit 4 side and to provide the exhaust device 33 having the axial center thereof provided with the exhaust fan 33 in the direction crossing the transport direction of the transport elevator 10 in plan view, Since the axial direction of the dust exhaust fan 33 is horizontal in the front view, the dust is discharged to the side more efficiently than in the case of the vertical direction, the exhaust efficiency is improved, and the dust is scattered around the machine body. To prevent That is, the dust discharge opening 3 of the top plate 28
1 is provided with a dust exhaust fan 33 having a vertical axis.
In this case, a duct directed from the upper side to the side is mounted. In this case, the exhaust air from the exhaust fan 33 is the strongest and then weakens, and the dust exhausted from the duct scatters around. When the suction force of the fan 33 is increased,
May aspirate up to grain. Therefore, by adopting the above configuration, the dust discharging efficiency is improved without sucking the grains, and the dust is not scattered around.

Thus, the dust exhaust fan 33 has its fan rotating shaft 34 mounted on the dust discharging hood 32 and the fan rotating shaft 34.
, The rotation of the transport elevator 10 tuned to the traveling speed of the machine is controlled by the dust exhaust fan 33.
When the vehicle is traveling at a high speed, the vehicle rotates at a high speed when traveling at high speed, at a low speed when traveling at low speed, and rotates at a predetermined constant speed when the speed is lower than a predetermined speed. In another embodiment of the dust exhaust device 30 shown in FIGS. 16 and 17, the cross flow fan 36 is provided above the dust discharge opening 31. Since it becomes substantially the same in any case in the axial direction of 36, there is no uneven suction and the dust discharging efficiency is improved.
That is, in the propeller type (axial flow type) fan, the size of the dust discharge opening 31 is substantially the same as the diameter of the propeller type fan, and the opening area is small. When the diameter is increased as well as the length can be increased in accordance with the width of the transport elevator 10, the opening area is increased in the front-rear direction to improve the dust removal efficiency. In another embodiment of the dust discharging device 30 shown in FIG. 18, when the top plate 28 of the transport elevator 10 has a high intermediate portion in the transport direction formed in a triangular shape in a side view, the dust discharging device is provided on the top 39 thereof. Since the 30 is provided, suction in the transport elevator 10 can be optimally performed. That is, if the dust exhaust device 30 is provided on one side portion other than the top portion 39, the suction on the other side portion will be performed with a large space near the top portion 39 interposed therebetween, which is irrational and the suction efficiency is low. However, by adopting the above-described configuration, the dust exhaust efficiency is improved.

A work lamp 41 is provided on the upper surface of the side plate 40 on the operation unit 4 side of the table 9, and on the upper surface of the side plate 40,
The plate-like member is erected so as to be higher toward the terminal end, and its starting end is a weeding body 43 provided at the front end of the side plate 40.
, And the end portion is provided with a transport cover 42 formed in a protruding cover portion 44 located above the work light 41 by cutting out the portion of the work light 41. Since the grain stalk is guided by the projecting cover portion 44 above the work light 41 while preventing the interference of the transport cover 42, the transfer to the auger 8 is improved, and the height of the side plate 40 is increased. Thus, grain loss from the ear side of the grain stem is prevented, and head loss is reduced. Behind the rear wall 45 of the table 9 of the mowing unit 5, reel blades 47 arranged in a circumferential direction are mounted on a pair of left and right arms 48, and the base of the arm 48 is rotatably fixed. , The remaining culm is cut by the second cutting blade 46 which rotates in the horizontal axis, and is simultaneously diffused rearward. In addition, since the second cutting blade 46 is configured to rotate and cut, there is no need to change the rotational power into reciprocating motion as in the clipper type, so the transmission mechanism is simplified, and the weight and cost are reduced. In addition, low noise and low vibration can be realized, and the cutting is performed by the continuously rotating second cutting blade 46, so that the cutting mark becomes beautiful. In addition, the second cutting blade 46
The work is always rotated, so that the mud adheres little due to the centrifugal force, and the body sinks like a wetland and the second cutting blade 46
Can work stably even in the situation where it is easy to come into contact with the field scene.

Further, since the cutting is performed by the continuously rotating second cutting blade 46, the remaining grain culm is also likely to be finely cut, and this is spread in the field, and the rotation of the crawler of the traveling device is stabilized. That is, especially in a slippery state like a wetland, the cut cereal stem is located between the crawler and the field scene to reduce the occurrence of slip and stabilize traveling. Further, the reel blade 47 has a base portion rotatably mounted on a pair of left and right floating rotators 50 by a shaft 51 so as to be rotatable.
0 is fixed to the rotating cylinder 52, the rotating cylinder 52 is freely rotatably fitted to the rotating shaft 53, the floating rotator 50 is provided with a fitting groove 54, and the fitting body 55 is fitted in the fitting groove 54. , Fitting body 55
Is fixed to the rotating shaft 53, and a spring 56 is provided between the fitting body 55 and the fitting groove 54 so that the reel blade 47 urges the rotating shaft 53 in the counter-rotating direction. Since the rotating body 58 is movably mounted on the elongated hole 59 fixed to the rotating shaft 53, when a load is applied to the reel blade 47, the floating rotating body 50 changes its phase with respect to the rotating body 58, and the reel blade 47 47 moves the tip first with respect to the base, inclines, and comes into contact with the cereal stem at an acute angle.
Therefore, not only can cutting be facilitated, but also a load sensing mechanism can be mechanically built in between the floating rotating body 50 and the rotating body 58, and external control is unnecessary. The setting of the load sensing mechanism can be changed by making the spring 56 changeable.
