Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an oscillating sorting adjusting device for a self-removing combine, in which an oscillating sorting body in a threshing section can reduce the No. 3 loss to oscillate and sort objects to be sorted.

[0002]

2. Description of the Related Art Conventionally, a first chaff sheave and a second chaff sheave, each fin of which is adjustable in inclination angle, are provided at a portion of a rocking sorting body on the lower side of a handling chamber and the upper side of a second conveyor. It is known that, in the self-removing combine as described above, the angle adjustment of the fins of the first chaff sheave and the second chaff sheave is performed separately, as seen in Japanese Utility Model Laid-Open No. 2-111235.

[0003]

However, since the fins of the first and second chaff sheaves are not designed to change the inclination angle at the same time, when the machine is traveling on the headland side in the field, the drainage is eliminated. When the fins of the first chaff sheave are gently tilted to improve the sorting ability due to a small amount of straw, if the second chaf sheave is set to be particularly gentle, it is sent from the first chaff sheave. There was a problem that the sorted objects would be sent to the mouth 3 with almost no leakage, and the loss 3 would increase.

[0004]

The present invention solves such a problem and makes it possible to effectively reduce the No. 3 loss in the sorting by the swing sorting body. In the self-removing combine having the first chaff sheave and the second chaff sheave, each fin of which is adjustable in tilt angle, is provided in the upper part of the swinging sorting body of the No. 2 conveyor. Inclination angle of each fin can be adjusted to a plurality of initial setting positions in advance, and the straw amount detection device installed in the straw chain of the threshing section reduces the straw amount and gently tilts the fins of the first chaff sheave. When this is done, the fins of the second chaff sheave can be changed from the initial setting position to a steep inclination, so that the fins of the first and second chaff sheaves simultaneously conflict with each other based on the increase or decrease of the amount of straw. That it is constructed by the adjustable in inclination direction.

[0005]

Therefore, if the inclination angle of each fin of the second chaff sheave is preset to any of a plurality of initial setting positions according to the threshing state, the threshing amount increases during the threshing work, and the threshing amount is increased. Even when the fins of the first chaff sheave are steeply inclined by the detection device and the swing selection is favorably performed, the fin of the second chaff sheave favorably swings and sorts the second object in a preset inclination posture. When the aircraft travels on the headland side of the field, the straw amount detecting device detects that the straw amount is small, and each of the first chaff sheaves is leaked. The fins can be gently tilted, and at the same time, the fins of the second chaff sheave can be steeply tilted from the state of the initial setting position, and the remaining scoop sent out from the first chaff sheave. There will be a number 2 of the sorted matter in can be better than leakage please second chaff sieve,
You can effectively reduce the 3rd loss.

The intermediate part of the above is interlockingly connected to the interlocking plate 21 via a connecting pin 24, and the fins 1a are elastically pressed between the stay 25 installed in front of the arm 22 and the tip end of the arm 22 so as to gently incline each fin 1a. A distal end of a wire 28 extending from a wire receiver 27 provided behind the arm 22 is connected to the end of the arm 22 via a tension spring 26 that urges the arm 22.

The second chaff sheave 2 has substantially the same structure as that of the first chaff sheave 1 as indicated by the same reference numeral, and the inclination angle of each fin 2a can be adjusted in advance to a plurality of initial setting positions. However, the adjustment plate 29 erected on the side plate 18 where the distal end 21a of the interlocking plate 21 is located is capable of colliding with the distal end 21a of the interlocking plate 21 that is pulled and biased by the tension spring 26. Three adjustment holes 31a, 31b, 31c, which are different in the positions into which the pins 30 can be inserted, are formed, and the initial setting positions are three.

Further, a device C for detecting the amount of straw is provided at the rear of the straw chain 5, and the device C moves up and down together with the sling rod 6 which is vertically moved by the amount of straw while being elastically pressed by the compression spring 16. The support rod 15 on the rear side, and the support rod 15

When 1a abuts the setting pin 30, each fin 2a of the second chaff sheave 2 can favorably swing and select the No. 2 object in a preset tilted posture to allow the second object to leak.

Further, when the machine is traveling on the headland side of the field, as shown in FIG. 3, the amount of straw discharged by the straw chain 15 decreases, and the supporting rod 15 rises together with the sling rod 6. Then, the fins 1a of the first chaff sheave 1 are gently inclined by the tension spring 26, and at the same time, the wire 28 is pulled while the detection arm 33 is rotated by the tension spring 38. The fins 2a can be steeply tilted at the initial setting position, and the second object being sorted, which is fed from the first chaff sheave 1 and has a small remaining amount, can leak better than the second chaff sheave 2. Therefore, the third loss can be effectively reduced.
