Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a swing sorting apparatus having a Glen pan into which a processing object is dropped and supplied from a starting end of a handling chamber and a chaff sheave which inherits the processing object from the Glen pan. The present invention relates to a threshing device provided in a vehicle.

[0002]

2. Description of the Related Art In the above-described threshing apparatus, the gap between the orbiting sorting apparatus and the wall of the threshing machine is filled with a sealing material attached to the frame of the orbiting sorting apparatus.

[0003]

Conventionally, the seal material moves with respect to the wall of the threshing machine together with the rocking and sorting device with the drive of the rocking and sorting device. For this reason, if processed material such as straw waste leaks from the grain pan to the outside of the rocking sorting device, the processed material spills from between the sealing material and the wall of the threshing machine to the bottom of the sorting unit, or falls outside the threshing machine. Sometimes it spilled out. SUMMARY OF THE INVENTION An object of the present invention is to provide a threshing apparatus capable of simplifying the structure of a processed product leaked from a grain pan from spilling out of the machine and improving the sorting performance.

[0004]

The constitution, operation and effect of the invention according to claim 1 are as follows.

[Structure] A swinging sorting device having a Glen pan into which a processed material is dropped and supplied from the starting end of a handling chamber and a chaff sheave inheriting the processed material from the Glen pan is provided in a sorting portion so as to be capable of driving and swinging. In the threshing device, a blower that supplies a sorting wind from a rotating pan to the processed material transferred from the Glen pan to the chaff sheave is provided at a front end side of the sorting unit, and an intake port of the blowing unit is a starting end of the Glen pan. It is formed upward so as to act on the side.

[Operation] The processed material from the grain pan is transferred to the chaff sieve while being subjected to the sorting action by the sorting wind from the blower, and the grains and the dust are separated during the sorting processing by the chaff sieve for the wind sorting. This makes it difficult to mix dust into the first processed material. When processed material such as straw waste that has leaked from the Glenpan to the outside of the rocking sorter spills from between the rocking sorter and the threshing machine wall, it is sucked into the blower together with the air sucked by the blower and the sorting wind. Is sent to the sorting room. Then, it will be discharged as a sorted product from the dust outlet together with the sorting wind to the outside of the threshing machine, and it will not be spilled as a leaked matter at the bottom of the sorting unit or below the threshing machine as in the past, and it will not be accumulated. Less.

[Effect] Even if the processed material leaks out of the grain pan, it is difficult to be in a state where it is necessary to clean up by accumulating on the bottom of the sorting unit or below the threshing machine, or it takes time and effort for cleaning. It was possible to improve the sorting accuracy. In addition, the prevention of the accumulation of the processed material and the improvement of the sorting accuracy can be achieved with a relatively simple structure using the same air blower, and the cost can be improved.

The structure, operation and effect of the invention according to claim 2 are as follows.

[Structure] In the structure according to the first aspect of the present invention, a guide device is provided for guiding the processed material, which has come out of the swing sorting device from the Glen pan, toward the rotating fan.

[Effect] Even when the suctioned effect of the blower is hardly effective due to the relatively heavy processed material leaking from the Glen pan, the guide is fed to the rotating fan with high accuracy.

[Effect] Even if the processed material leaked from the Glen pan is difficult to be sucked into the blower, it is accurately sent to the blower to further prevent the accumulation of the leaked matter at the bottom of the sorting unit or below the threshing machine. It is easy to do.

The structure, operation and effect of the invention according to claim 3 are as follows.

[0013] [Constitution] In the constitution of the invention according to claim 2, a guide body attached to a threshing machine wall so as to guide the processed material which has come out of the swing sorting device from the Glen pan toward the suction port, The guide device is constituted by a receiving member provided in the blower so as to receive the processed material from the guide member and to introduce the processed material into the rotating fan.

[Operation] A gap is provided between the guide body and the receiving body, and it is possible to reliably perform the intake by the blower through the gap. Even if the processing object falls from the guide body toward the outside of the air inlet, it is received by the receiving body and sent to the rotating fan.

[Effect] It is possible to reliably improve the sorting accuracy by configuring the blower so as to reliably inhale and sufficiently supply the sorting wind. In addition, the processed material leaked from the Glen pan is reliably sent to the rotating fan not only by the suction action of the blower and the guide action by the guide body but also by the action of the receiving body, so that the accumulation of the leaked material is further easily avoided. .

It is configured to do so.

That is, the sorting section is configured to sort the processed material from the handling room 2 by the swing sorting device 10 and the blowers 21, 22, and 23 as follows. The processed material dropped and supplied from the starting end of the handling room 2 through the receiving net 8 is received by the first Glen pan 11 and conveyed to the rear of the machine body while being sorted by specific gravity. By the sieving action of the sieving line and the sorting action of the sorting air from the first blowing device 22, the chaff sieve 12 is dropped onto the starting end while being easily separated into grains and straw chips. The chaff sieve 12
While conveying the processed material from the first Glen pan 11 and the reprocessing unit to the rear of the fuselage, the specific gravity sorting is performed, and the second blower 2
The selected grains are dropped and supplied to the second Glen pan 14 and the Glen sheave 15, and the dust is discharged out of the machine together with the sorting wind or conveyed to the straw rack 13. Second Glen Pan 14 and Glen Sheave 1
