BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sorting device for a self-removing threshing device mounted on a combine or the like.

[0002]

2. Description of the Related Art Conventionally, an oscillating sorter is installed in a sorting air passage below a handling room, and the oscillating sorter is firstly screened on a receiving gutter, and a most-leakage sorting unit is provided. A transfer unit for transferring the sorted material leaked from the receiving net to the above-mentioned most leak sorting unit, and a second leak for sorting the sorted material transferred from the end of the most leak sorting unit on the second receiving gutter. A lower sorting unit, a sorting object amount detector is provided on the transfer unit, and a leak area of the lowest leak sorting unit is adjusted based on a detection result by the sorting object amount detector, or a chaff sieve is provided. It is already known to adjust the eyes of a person.

[0003]

In the known threshing machine sorting apparatus, the amount of threshing increases or decreases depending on the type of grain culm to be threshed, cutting conditions, or the like. And when the amount of threshing is small, the layer of the material to be sorted becomes extremely thin, so that the detection result of the material amount to be sorted detection body adjusts the leak area of the most leak-selecting portion or adjusts the size of the chaff sheave. Could not be performed accurately.

[0004]

According to the present invention, there is provided a transfer section for transferring, to a sorting air passage below a handling room, a sorting object leaked from a receiving net of a handling room to a rear side, and a transferred sorting object. A swing sorting body having the most leak sorting part for sieve sorting on the first gutter is installed so as to swing back and forth, and a second transfer spiral is installed behind the most leak sorting part. the provided受樋in threshers provided to be sorted amount detecting member on said transfer unit, disposed to the object to be sorted amount detecting member on the opposite side near the扱口transfer portion, of the object to be sorted amount detecting member The above-mentioned problem has been solved by arranging a sloping plate on the transfer section behind the plate to guide the object to be sorted toward the center of the swinging and sorting body.

[0005]

[Operation] The to-be-handled material generated in the handling room leaks from the receiving net to the transfer section of the swinging sorting body, where the sorted objects are sequentially transferred for swinging operation, and the sorting object is transferred to the opposite side of the handling port. An object for detecting the amount of the sorted object rides on the object to be sorted and detects the amount. At that time, the sorting plate is arranged behind it, so that the sorting object to be transferred is received and moved to the center side and the layer becomes thicker, and even if the sorting object amount is small, the sorting object amount detector is The thickness is accurately detected, and a large amount of water leaks to the opposite side of the swing sorting body from both the bottom and top types.
The sorting plate sends it to the center side, so that the sorting object is almost uniform over the entire width of the swing sorting body. Thus, it is possible to prevent the cut straw and the like from falling into the gutter first.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The threshing machine shown in the drawings will be described in detail. A handling room 2 having a handling cylinder 1 mounted on a shaft has a handling port on one side, and is caught by a feed chain 3a along the outside thereof. A holding and conveying device having a rail 3b opposite thereto is provided, and a blower windmill 6 below the supply port 5 and a suction windmill 7 provided above the rear side opposite to the handling port are provided for sorting dust from below the handling room receiving net 8. A sorting air path is formed through the chamber 10, and a processing chamber 13 in which a processing drum 12 is provided is provided behind the dust outlet 11 on the side of the feed chain 3a so as to swing back and forth in the sorting air path. The swinging sorting body 15 erected is composed of an upper transfer plate 16 composed of a wavy upper transfer plate 16 and a chaff sheave 17 composed of a large number of fins 19a that follow and tilt forward and backward.
Corrugated lower transfer plate 18 and the next most ditch 19
A lower transfer sorting path composed of a crimping net that faces upward, a lower transfer sorting path, and a second leak sorter 23 that is composed of a rear transfer plate 21 and a straw rack and faces the second receiving gutter 22. , The first flow plate 24, and the second flow plate 24 a, and the cross flow fan 25 interposed between the first drainage gutter 19 and the second drainage gutter 22 is moved from the wide air guide tube 27. It blows through the second leak sorting section 23. 29 is a dust sorting room 10
, Which transports and supplies the straw to the disk cutter 30.

[0007] Further, on the side of the upper transfer plate 16 opposite to the handling port, there is provided a float-type material quantity detecting body 32 of a float type rotatably supported at the tip of an arm 31. Is connected to a swing arm protruding forward from the long hole of the front wall, and the swing arm is connected to the potentiometer, so that the thickness of the sorting object detected by the sorting object amount detecting body 32 is detected. Is detected as a voltage, and based on the detection result, the driving body of the closing plate 33 slidable back and forth, which is superimposed on the leakage selection section 20, and the driving body for tilting the fins 19a are controlled.

The object-to-be-sorted detection body 32 is located near the end of the upper transfer plate 16 and has a rear plate inclined toward the center of the swinging separation body 15 on the fin 19a immediately after it in plan view. An outer end of the pulling plate 35 is fixed to a side plate of the swinging sorting body 15, and the sorting object is sent to the center side for swinging operation. Also, a pair of front and rear lower shift plates 36 and 37 are attached to the lower transfer plate 18 on the opposite side of the opening (the same side as the shift plate 35), and these shift plates 36 and 37 are also sorted objects. To the center of the width of the swing sorting body 15.

The air guide tube 27 is formed by fixing both sides of a parallel upper plate 27a and a lower plate 27b to left and right side plates, and the rear portion is slightly displaced outward toward a side opposite to the handling port. The partition plate 38 is fixed so that the partition plate 38 is inclined.
The lower portion 8 is arranged close to the rotation trajectory of the cross flow fan 25, and a net 26 is stretched over the upper end, the upper end of the upper plate 27a, and the upper end of the lower plate 27b. The net 26 faces immediately before the end of the transfer of the second trough 22, and the second material transferred by the second transfer spiral 22 a is the second reduction pumping connected to the end of the second trough 22. The spiral cylinder 39 returns the rocking sorting body 15 to the upper transfer path. At this time, the second thing is rebounded by the lifting spiral at the lower part of the second reducing and pumping spiral cylinder 39, so as to stagnate and jump up to the discharge portion of the air guide cylinder 27. Although the movement of wind and the wind selection on the transfer terminal side of the second gutter 22 are deteriorated because the wind force is weakened by the frictional resistance as compared with the central part, the wind is generated on the transfer terminal side of the cross flow fan 25. Sorting style, partition plate 3
By 8, it flows backward as it is so as not to flow to the center side, and blows over the end of the second receiving gutter 22, whereby the above-mentioned problem can be solved. Net 26
Prevents the bounced grains and the like from falling into the air guide tube 27.

In the above-described threshing machine, the sorted objects generated in the handling room 2 and leaked from the handling room receiving net 8 fall onto the upper transfer plate 16. At this time, since the handling cylinder 1 is subjected to grain removal processing on the ears inserted on the opposite side of the handling chamber 2 from the handling port, the handling cylinder 1 leaks a lot on that side, and the object to be sorted amount detection body 32 rides thereon. The thickness is detected. In this detection state, when threshing conditions are good, or when threshing amount is larger than wheat, such as rice, the detection is carried out to perform appropriate detection. However, if the amount of thresh is small, such as when threshing low efficiency or threshing wheat,
Although it is impossible to perform proper detection since the amount of change is small, the site close to the right after the該被sorting amount detecting member 32 i.e.
Behind it, there is provided a shift plate 35, so that the threshing material to be transferred is received by it and stagnates while being rocked.
And the stagnation spreads to the object-to-be-detected amount detection body 32 and the layer of the object to be selected becomes thicker, so that the amount of change is amplified and the amount of the object to be selected is ensured. In addition, immediately before the approaching plate 35, the stagnation target material is subjected to the rocking operation, and the kernels leak from the chaff sheave 17, and those that have leaked from the other side are also transferred downward. Entered the sorting route and received wind and sieve sorting,
The straw chips and the grains mixed therein are transported rearward by the chaff sheave 17 and moved to the second leak sorting section 23.

Further, the sorted material which has moved to the lower transfer sorting path is sent to the handling port side by two lower pulling plates 36 and 37 separated by a narrow inflow gap on the opposite side of the handling port, and is dispersed. The sifted and filtered sifters are passed through the spillage sorting unit 20, and the spilled kernels fall into the receiving gutter 19 and are transported and discharged by the helical transporter and the sifting cylinder. The objects to be sorted which have been charged into the tank and have reached the end of the first leak sorting unit 20 and those which have leaked from the processing room receiving net 13a of the processing chamber 13 and have not leaked from the first leak sorting unit 20 are The process moves to the rear transfer plate 21 and the processing chamber 1
On the 3rd side, it is sent to the center side by the rear gathering plate 40 and reaches the second leak sorting section 23, where it is subjected to the wind selection and the leak sorting, and the leaked second product is reduced to the second as described above. The straw waste is discharged outside the machine by upper and lower suction fans.

[0012]

According to the present invention, a transfer section for transferring the sorted objects leaking from the receiving net of the handling room 2 to the sorting air passage below the handling room 2, and the transferred sorted objects on the receiving gutter first. An oscillating sorter 15 having a most-leakage sorting part 20 to be sieved is erected so as to swing back and forth.
In the threshing machine in which the second receiving gutter 22 provided with a is provided and the sorted object amount detector 32 is provided on the transfer unit, the sorted object amount detector 32 is disposed closer to the side opposite to the port of the transfer unit. and setting, on the transfer section behind the object to be sorted amount detecting body 32, since the attracted plate 35 to induce the sorted matter toward the center of the swing sorting member 15 and obliquely,扱口of oscillating sorting member 15 On the opposite side, the sorted object amount detector 32 detects the sorted object amount.
The gathering plate 35 provided behind the sorting plate 35 receives the sorting object and sends it to the other side, thereby averaging the sorting object in the width direction of the swing sorting body 15 and partially stagnating the layer to thicken the layer. As a result, even when the amount of the sorted material is small, such as at the time of low-efficiency threshing, the sorted material amount detector 32 accurately detects the sorted material amount, appropriately performs various controls based on the detection result, and performs good sorting. It can be carried out.
