Spiral gutters 70, 71 to be fitted and fitted are arranged at a predetermined interval. 72 is 2
It is a reducing spiral cylinder for returning the number grain to the upper surface of the swinging sorting shelf 57 on the starting end side, and the discharge port 73 thereof is provided on the inclined upper surface side of the sorting shelf 57 that is inclined to the left and right to mix the reduced straw waste. The second grain is slid down to the left while tilting to the front and back, and is quickly dispersed on the upper surface of the shelf.

A cross-flow suction device 74 is also called a sirocco fan, and sucks dust together with air from the left and right width and discharges it out of the device. Next, the operation of the above example will be described. The harvesting and conveying device 11 is lowered by the hydraulic cylinder device 16 and self-propelled to perform threshing work while harvesting rice in the field.

That is, while the planted rice is being weeded by the vegetation body 12, the raised body 13 raises the laid-down rice, and the root portion of the rice is cut by the cutting blade, and then the cut rice culm is conveyed. At 14, the tip end side is changed to the sideways state in which the tip end side is moved to the right while being transferred upward, and thereafter, the thresher 7
The root side is delivered to the feed chain 8 and transferred to the rear.

The grain culm thus cut and transferred is supplied to the handling chamber 17 of the thresher from the supply port 38 at its tip end side, and is directly transported to the rear inside the handling chamber 17 by the feed chain 8. Then, the rotation of the handling cylinder 22 and the processing cylinder 25
In response to the rotation of, the threshing and the processing of the object to be processed are performed in the handling chamber 17 and the processing chamber 18. That is, the grain culm is threshed below the handling cylinder 22 by the handling teeth 23 and the threshing net 19, and the tip grain is leaked to the underside of the threshing net 19. Further, the straw and the tip portion cut by the action of the handling tooth 23 also become the object to be treated and the handling body 25
It turns in the handling room with the rotation of. At this time, the processing cylinder 25
Is rotating toward the upper side, which is the opposite side of the handling cylinder 22, and the spiral chamber 27, the processing teeth 28, the processing rod 29, and the like fixed to the peripheral surface of the processing cylinder 25 are rotated so that the processing chamber 17 and the processing chamber 1 are rotated.
The object to be treated is taken into the processing chamber 18 through the opening communication part K ₁ between the eight and the opening communication part K ₂ , and the processing net 20, the cutting blade 37,
By the interaction of the processing rods 29 and the like, the object to be processed is finely cut and unwound and processed, and the grains stuck in the object are released from the object to be processed and the lower processing net 2
Leak from 0.

Further, the processing chamber 18 is rotated by the rotation of the processing cylinder 25.
Most of the object to be swirled therein is retained in the processing chamber 18 and is processed while being transferred rearward in the processing chamber 18.
This state of action is shown by the sectional view of FIG. 13 and the plan view of FIG. 14 by the moving arrow diagram of the object to be processed A. In FIG. In this state, as shown in FIG. 14, it is gradually transferred to the rear side, but the object to be processed is mainly put into the processing chamber 18. That is,
In FIG. 4, when the object to be processed in the handling chamber 17 is put into the processing chamber 18, it is taken in from the first opening communication part K ₁ and the second opening communication part K ₂ , Most of them are transferred to the rear while being processed in the processing chamber 18. That is, straw is freely introduced into the processing chamber 18 from the two opening communication parts K ₁ and K ₂ , and the third opening communication part K _{3 is} opened.
Then, due to the action of the emitter 31, it is reduced toward the front side in the handling chamber 17. That is, as shown in FIG. 14, the object A to be processed A is discharged to the opposite side of the handling chamber 17 from the state in which it is transferred to the rear side, as shown in FIG. To do. And again the handling room 17
The object to be processed fed into the inside is threshed while being transferred to the original rear side, and is dropped and discharged from the discharge port 39 at the lower portion of the rear end side of the handling chamber 17 onto the swinging sorting shelf 57 below. On the other hand, the object to be swirled and transferred to the processing chamber 18 side is processed while being transferred backward in the processing chamber 18 by the spiral transfer body 33,
It is discharged downward from the processing chamber discharge port 75 which is opened on the rocking sorting shelf 57.

Therefore, the material to be treated A generated during threshing
In the processing chamber 18, most of the material is thrown into the processing chamber 18 through the opening communication portions K ₁ and K ₂ and a large amount of the object A is rapidly processed, and all or part of the object A is again processed from the processing chamber 18. Handling room 1
It is reduced to 7 and threshed. For this reason, treatments such as dispersion, cutting, and threshing are performed with high efficiency, and when it reaches the end side of the handling chamber 17, it is as if discharged in the arrow (d) direction by the emitter 31 provided in the processing cylinder 25. It moves in a substantially γ shape and is transferred in the handling chamber 17 through the corresponding part of the emitter 31, that is, the opening communication part K ₃ at the rear part. Therefore, the treatment process can be sufficiently ensured and the object to be treated can be accurately treated, and the treated object is dispersed from below the discharge port 39 at the rear end of the handling chamber 17 and the extension portion of the processing cylinder and shakes downward. It is discharged onto the dynamic selection shelf 57.

By the way, in the handling chamber 17, cutting teeth 54 as resistors are arranged at positions corresponding to the opening communicating portions K ₁ and K _2, and the object to be processed is rotated along with the rotation of the handling cylinder 22. However, the cutting tooth 54 mainly receives long straws and stagnates, and the objects to be sequentially sent are given resistance by the cutting teeth themselves or the stagnation thereof, so that the objects to be sorted are Processing chamber 18 from opening communication parts K ₁ and K ₂
It can facilitate the transition to the side. However, since there is nothing to impart resistance to the opening communication portion K _3, it is easy for the straws and the like to go around to the handling cylinder 22, and the reduction treatment product from the processing chamber 18 side can be taken into the circumferential surface of the handling cylinder 22. Becomes
In addition, the first (close to the entrance) partition strip plate 5 of the handling room 17
1 ₁ The partition strip 51 to be treated to be moved rearward along with the rotation from the inlet resisted the threshing drum 22
_{Although the} amount of the object to be processed in the range up to ₁ increases, a part of the object moves to the processing chamber 18 through the opening communication portion K ₁ while receiving the action of the resistor (cutting teeth 54 ₁ , 54 ₁ ). Second
Although the amount of the object to be processed decreases while it reaches the partition strip plate 51 ₂ of No. 1, it is still generated, and similarly, the resistor (cutting tooth 5
The object to be processed enters the inside of the processing cylinder 18 through the opening communication portion K ₂ with the action of 4 ₂ and 54 ₂ ) (FIG. 12).

By the way, during the processing of the object to be processed, the load on the processing cylinder shaft 43 is constantly detected by the load detector 80,
The detection output is input to the control unit 81. When the detected output exceeds a preset appropriate value, the control unit 81 determines that it is overloaded and outputs a normal rotation command signal to the control motor 86. For this reason, the cutting teeth 54 move upward to reduce the resistance, so that the number of processed objects that go around in the handling chamber 17 increases and the amount of transfer to the processing chamber 18 can be reduced. When the load on the processing cylinder shaft 43 becomes less than a certain value, a reverse rotation command signal is output to the control motor 86 to restore the cutting teeth 54 to the original position.
In this way, the amount of the processed material taken into the processing chamber 18 side can be controlled by the load of the processing cylinder shaft 43, so that the processing chamber 18 is not clogged due to overload.

The grains dropped and discharged as described above on the rocking sorting shelf 57 and the treated objects such as the processed cullets and straw wastes are subjected to the sorting action, and the fine grains are transferred to the Glen tank 9. It is thrown in and temporarily stored. Further, the branch-bead-attached particles and the like are returned to the front part of the swing selection shelf 57 to be re-sorted. Straws, etc.
It is discharged to the outside of the threshing device 7. The grain stored in the Glen tank 9 is discharged and loaded on the loading platform of the truck at the end of the field by the discharging spiral.

In the above-described embodiment, the rotation of the cutting teeth 54 is used as the means for controlling the amount of the object to be processed after the overload is detected. However, the resistance is switched to the standard position and the retracted position in the same manner by using different resistors. But it's okay. Further, as shown in FIG. 13, resistance plates 90 and 91 that change the opening area of the communication openings K ₁ and K ₂ by a load are rotatably provided around a lower fulcrum shaft 92, and an external resistance is detected when an overload is detected. Alternatively, the plates 90 and 91 may be erected to narrow the areas of the communication openings K ₁ and K ₂ to limit the introduction of the object to be processed. In this embodiment, a second resistance plate 93 is also provided in the communication opening K ₃ to reduce the discharge at the time of overload and the resistance of the object to be processed is alleviated at once, resulting in an extreme fluctuation of the processing resistance. It is configured not to.

In both the first embodiment and the other embodiments described above, the rotation speed of the control motor 86 is controlled according to the overload condition to finely control the retracting movement of the cutting tooth 54 as a resistor, or the resistance plate. The standing angles of 90 and 91 may be finely controlled. As a means for detecting the load of the processing chamber 18, in addition to detecting and outputting the rotation of the processing cylinder 25 to the shaft 43 as in the above-described embodiment, another configuration such as detecting the amount of the object to be processed may be used. In the case of detecting, it is easy to detect the magnitude of the load and it is easy to understand the load fluctuation.
