Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a sorting device for a self-throwing thresher mounted on a combine or the like.

[0002]

[Prior Art]

 Conventionally, an oscillating sorting body is installed in the sorting air passage below the handling room, and the oscillating sorting body is the most leaking type in which the objects to be sorted which have leaked from the receiving net of the handling room are sieve-sorted on the most gutter. It consists of a lower sorting section and a second leakage sorting section that screens the objects to be sorted that have moved from the end of the first leakage sorting section on the second trough, and the first trough and the second trough. A sorting device in a threshing machine is already known in which a cross-flow fan that blows diagonally upward and backward over the second gutter is provided.

[0003]

[Problems to be solved by the device]

 In the above-mentioned known thresher sorting device, when the second product leaking from the second leakage screening section is wind-selected by a cross-flow fan, it is transferred while being stirred by the second transfer spiral in the second trough. The amount of the second object is the largest at the end of the transfer, and even though the second object is bounced or stagnated when the transfer direction is changed upward by the second reducing device at the end of the transfer. Since the wind force of the sorting wind sent by the cross flow fan is weaker in the side part than in the central part, the amount of the secondary product reduced due to insufficient wind selection was large. Moreover, the grains bounced off at the transfer end of the No. 2 gutter were scattered outside the machine through the air guide tube.

[0004]

[Means for Solving the Problems]

 According to the present invention, an oscillating sorting body is installed in the sorting air passage below the handling room, and the oscillating sorting body is the most leaking sorting section for sieving on the first gutter and the receiving net of the handling room. It has a transfer section for the leaked sorted object toward the most leaked sorting section, and the second gutter after selecting at least the sorted matter thrown from the end of the most leaked sorting section. A cross-flow fan that blows diagonally upward and backward over the second gutter is installed between the first gutter and the second gutter, and a second reducing device is connected to the end of the second gutter. In the threshing machine installed, a partition plate in the front-rear direction is provided on the end side of the second article transfer inside the wind guide tube attached to the cross flow fan to divide the air guide passage, and the discharge of the divided air guide passage is divided. The above problems were solved by installing a net at the exit.

[0005]

[Action]

 The unloading material generated in the handling room leaks from the receiving net onto the rocking sorting body, and first, the first leaking sorting section receives the sieve sorting and the wind sorting, and the grain dropped into the first trough. Is carried out of the machine, and the objects to be sorted that have been thrown from the most leaking sorting section onto the second trough are wind-selected by the selective wind from the crossflow fan and fall into the second trough. The No. 2 transfer spiral carries it to the side of the machine body, and then the No. 2 reduction device returns it to the swinging sorting body (or the handling room). Then, when the second fan is wind-selected by the cross flow fan, of the selection winds blown by the cross flow fan, the selection wind on the transfer end side of the second transfer spiral is divided by the partition plate and weakened. Accurately select the second product that blows out only to the transfer end side and leaks from that part, and the second product that is agitated by the second transfer spiral at the transfer end part and that is bounced back by the second reducing device. Then, the straw waste is removed, and the net prevents the grains from scattering outside the machine.

【Example】

 The present invention will be described with reference to the threshing machine shown in the drawings. The handling chamber 2 in which the handling barrel 1 is mounted on the inside has a handling opening on one side, and a feed rail 3a is provided with a clamping rail 3b along the outside thereof. An air blower 6 below the supply port 5 and a suction winder 7 provided on the upper side on the opposite side to the rear handling port, which is provided with the sandwiching and conveying device provided, extend from below the handling chamber receiving net 8 to the dust sorting chamber 10. A sorting air passage is formed, and a processing chamber 13 having a processing drum 12 therein is provided behind the dust inlet 11 on the side of the feed chain 3a, and the swinging air is installed in the sorting air passage so as to swing back and forth. The moving sorter 15 includes an upper transfer plate 16 and a lower transfer plate 18 having a corrugated upper transfer plate 16 and a chaff sheave 17 formed of a plurality of fins 19a. Following that, Krin looks at the top of the gutter 19 A lower transfer sorting path constituted by the first leak-through sorting section 20 made of a net, a second leak-through sorting section 23 consisting of a rear transport plate 21 and a straw rack and facing the second trough 22; The cross flow fan 25, which is composed of the numbering plate 24 and the numbering plate 24a and is interposed between the first trough 19 and the second trough 22, is provided with a wide air guide tube 27. It blows through the leaking sorting section 23. Reference numeral 29 denotes a straw conveying device provided above the dust sorting chamber 10 for conveying straw to the disc cutter 30.

Further, a float-type object-to-be-sorted quantity detection body 32 pivotally supported at the tip of an arm 31 is provided on the side of the upper transfer plate 16 opposite to the handle, and the arm is provided. The front portion of 31 is projected forward from the long hole of the front wall and is connected to the swing arm 31a. Since the swing arm 31a is linked to the potentiometer 31b, the object to be detected detected by the object 32 to be sorted is detected. The change in the thickness of the sorted material is detected as a voltage, and based on this detection result, the driving member of the closing plate which is slidable in the most leaking sorting portion 20 and which is slidable forward and backward and the fins 19a ... Control the body.

Further, the object to be sorted amount detecting body 32 is located near the end of the upper transfer plate 16, and the rear portion is inclined toward the center of the swing sorting body 15 on the fin 19a immediately after it in plan view. A plate 35 is provided, and the outer end of the plate 35 is fixed to the side plate of the swing selecting body 15 to move the objects to be sorted to the center side by the swinging action. Further, a pair of front and rear lower aligning plates 36 and 37 are attached on the opposite side of the lower transfer plate 18 from the handle (the same side as the aligning plate 35), and these lower aligning plates 36 and 37 are also objects to be sorted. Is sent to the center side of the width of the swing selection body 15.

The air guide tube 27 is configured by fixing both sides of the parallel upper plate 27a and the lower plate 27b to the left and right side plates, and the rear part is slightly outward toward the side opposite to the handle. A partition plate 38 that is inclined so as to be displaced is fixed, and the lower part of the partition plate 38 is made to follow the rotation trajectory of the cross flow fan 25, and the upper end thereof, the upper end of the upper plate 27a, and the upper end of the lower plate 27b. A net 26 is stretched over the discharge port formed by. The net 26 faces immediately before the end of transfer of the second gutter 22, and the second object transferred by the second transfer spiral 22a is continuously provided at the end of the second gutter 22 and is the second reducing device. Then, the second spiraling feed-back cylinder 39 reduces the secondary return to the upper transfer path of the rocking sorting body 15.

In the threshing machine described above, the objects to be sorted that have occurred in the handling room 2 and have leaked from the handling room receiving net 8 fall onto the upper transfer plate 16. At that time, since the ears inserted into the handling barrel 1 on the side opposite to the handling mouth of the handling chamber 2 are shredded, a large amount of the spillage occurs on that side, and the object to be sorted amount detection object 32 climbs on it. Detects its thickness. In this detection state, if the threshing condition is good, or if the amount of threshing is larger than that of wheat such as rice, it should be used to detect it properly. However, when the amount of threshing is small, such as when threshing low efficiency or threshing wheat, the amount of change is small and proper detection cannot be performed. Since the shifting plate 35 is provided, the transferred grain is received and stagnate and guided to the center side of the rocking sorting body 15 to be averaged in the width direction, and the stagnation is the amount of the sorted matter. Since the layer of the object to be sorted spreads to the detection body 32 and the layer of the object to be sorted is thickened, the amount of change can be amplified, and the amount of the object to be sorted can be detected with certainty. Was shaken and the grains leaked from the chaff sheave 17, and those that leaked from the other side also fell into the lower transfer sorting route and were subjected to wind sorting and sieve sorting, and were mixed with straw waste. Grains etc. are chaff sieve 17. Transported rearward proceeds to double dip Moshita sorting section 23.

Further, the objects to be sorted, which have moved to the lower transfer / sorting path, are sent to the handling port side and dispersed by two lower aligning plates 36 and 37 having a narrow inflow gap on the side opposite to the handling port. From the most leaking sorting section 20, the grain is subjected to sieve selection and wind sorting, and the leaked grain is dropped into the first receiving trough 19 and is transported and discharged by the first transport spiral and the lifting cylinder, and the grain is transported. Those that have been put into the grain tank and have leaked from the objects to be sorted that have reached the end of the most leaky sorting section 20 and from the processing chamber receiving net 13a of the processing chamber 13 and have not leaked from the most leaky sorting section 20. Moves to the rear transfer plate 21, and on the processing chamber 13 side, it is sent to the center side by the rear shift plate 40 and reaches the No. 2 leakage selection section 23, where it is subjected to wind selection and leakage selection, and has leaked. The second product is returned to the second product, and the straw waste is discharged outside the machine by the suction windmill 7.

Then, at the lower part of the second reducing-lifting spiral tube 39, the second object is bounced back by the lifting spiral and stagnates, and is about to be bounced up to the discharge part of the air guide tube 27. Since the wind force on both sides of the road is weaker than that on the center part, the movement of the second object and the wind selection on the transfer end side of the second trough 22 are deteriorated, but the wind is generated on the transfer end side of the cross flow fan 25. The separated sorting air flows rearward as it is so as not to flow toward the center side by the partition plate 38 and blows over the end of the second trough 22. As a result, the second sorting air leaked from the second leakage sorting section. The second product agitated by the second product and the second transfer spiral 22a and the second product bounced by the second reduction transfer spiral are accurately winded to remove the mixed straw and reduce the second reduction amount.
