Description

[Detailed description of the invention] [Industrial field of application] This invention relates to a threshing device in which a grain sieve for leakage is attached to a swinging sorting device for sorting out processed materials that have fallen from a receiving net in a handling room.

[Conventional technology]

Conventionally, in the above-mentioned threshing equipment, the effective area of the grain sieve can be changed freely at the conveyance start end side of the grain sieve in order to efficiently sort and process the grain sieve regardless of changes in the amount of the grain falling from the handling chamber. A structure equipped with a shielding grain pan has been proposed (for example, Japanese Utility Model Application Publication No. 44546/1983).

[Problem that the invention attempts to solve]

However, if the above-mentioned threshing equipment causes a large amount of processed material to fall from the receiving net in the handling room, it is possible to increase the effective area of the grain sieve and increase the sorting throughput, improving processing efficiency, but the amount of falling processed material is small. In some cases, even if the effective area of the grain sieve is reduced to improve the sorting performance in order to prevent straw waste from entering the material collection section, the rate of straw waste entering the falling material will still be low. Because of this, there was a risk that the sorting efficiency in the grain sieve would be poor and the recovery rate of the first material would decrease.

The present invention has been made in view of the above circumstances, and aims to provide a threshing device that can improve the grain recovery rate while suppressing the contamination of straw waste, regardless of changes in the amount of processed material falling from the handling room. purpose.

[Means for solving problems]

In order to achieve the above-mentioned purpose, the threshing device according to the present invention is a threshing device in which a grain sieve for leakage is attached to a swinging sorting device that sorts the processed material that has fallen from the receiving net in the handling room. The swing sorting device is provided with a grain pan for shielding the conveyance start end side of the grain sieve so that the shielding width can be changed, and below the discharge port of the handling chamber and the discharge port side portion of the receiving net, In addition, a receiving plate is provided above the grain sieve to receive the falling processed material from the handling chamber side and transfer it toward the conveyance end side, and the wrapping margin of this receiving plate with respect to the handling chamber in a plan view can be changed. and an interlocking device for interlocking the grain pan and the receiving plate in such a manner that the larger the shielding width of the grain pan with respect to the grain sheave, the larger the overlap margin between the receiving net and the receiving plate. The characteristic configuration is that

The functions and effects of this characteristic configuration are as follows.

[Effect]

In other words, the interlocking device reduces the shielding width of the grenpan and at the same time reduces the wrapping margin of the receiving plate against the receiving net, increasing the processing capacity for sorting the material when there is a large amount of material falling from the handling room. Although it can be made larger (see Figure 1), if there are few fallen objects to be treated, increase the shielding width of the grain pan and at the same time,
Focusing on the fact that there is a high rate of straw waste in the waste that falls from the outlet of the handling room and the side of the outlet of the receiving net, we increased the wrap margin of the receiving plate against the receiving net. , the rate of contamination of straw waste into the processed material falling onto the grain sieve can be reduced (see Figure 2), and good sorting can be achieved.

[Effect of idea]

Therefore, while it is possible to maintain high processing capacity when there is a large amount of material to be processed, when there is only a small amount of material to be processed, it is possible to improve the recovery rate while suppressing the incorporation of straw waste into the first material. As a result, it has been possible to improve the sorting and processing performance of the threshing device.

〔Example〕

Next, embodiments of the present invention will be described based on the drawings.

Figure 3 shows the schematic configuration of the threshing machine. The thresher includes a handling chamber 1 and a sorting chamber 2 below the handling chamber 1. In the handling room 1, there is provided a rotary handling cylinder 4 that threshes grain culms supplied by the feed chain 3, and along the lower outer periphery of this handling cylinder 4, there is a receiver for leakage of processed material. A net 5 is set up.
In addition, in the sorting room 2, there is a first grain sieve 6 for shaking and sorting the leakage from the receiving net 5, and a grain sieve 6 for separating the leaking material from the receiving net 5, and a grain sieve 6 for transporting the receiving net 5 to the end of the handling room without leaking. Upper and lower two-stage stroke racks 7, 7 that oscillately feed and sort the processed materials that fall from the discharge port 1a after
is fixed between a pair of left and right swing frames 8, 8, and a swing sorting device A is provided. At the bottom of the sorting chamber 2, there is a first material collection section 9 that collects and carries out the first material leaking from the grain sieve 6, and a straw rack 7 that collects and transports the first material leaking from the grain sieve 6, and a straw rack 7 that collects and transports the waste material that has fallen beyond the terminal end 6a of the grain sieve 6. A second object collecting section 10 is disposed at the front and rear for collecting fallen objects from the vehicle and returning them to the handling room 1. Further, in the sorting chamber 2 between the grain sieve 6 and the stroller rack 7 and both the collecting sections 9 and 10, there are provided a winnower 11 for blowing sorting air, a dust suction fan 12 for sucking and discharging floating garbage, etc.

As shown in FIGS. 1 and 2, on the conveyance start end side of the grain sheave 6, in order to change the leakage area of the grain sheave 6, a shielding grain pan that can move in and out along the guide rail 16 over the grain sheave 6 is shown. 13 is provided, and the discharge port 1a of the handling room 1 and the receiving net 5 are provided.
Below the discharge port 1a side part and above the grain sieve 6, the wrap margin in plan view with the handling chamber 1 can be changed, and the falling processed material from the handling chamber 1 is directed toward the conveyance end side. A receiving plate 22 to be transferred is provided, and the receiving plate 22 and the receiving plate 22 are arranged so that the wrap width between the receiving net 5 and the receiving plate 22 increases as the shielding width of the receiving plate 13 increases. 1
3 are interlocked and connected by a swingable link 14, this link 14 is connected to an operating lever 23 via a wire 15, and the receiving plate 22 and the grain pan 13 are interlocked by operating the operating lever 23. An interlocking device 24 is formed to operate, and the processing material received by the receiving plate 22 is arranged at the starting end side of the stroke rack 7 so that it is conveyed to the stroke rack 7.

[Another example]

The receiving plate 22 may have the same shape as the grain pan 13 or the grain sheave 6, and may have a number of holes for leakage in the same plate member as the grain pan 13. It is okay to use something that has already been done.

In place of the operating lever 23, a motor is provided that drives a transmission device that determines that the grain flow rate is small when the vehicle speed is slow and interlocks the receiving plate 22 and the grain pan 13 based on information from the vehicle speed detector. Alternatively, a device for detecting the volume of grain culms to be transported may be provided, and control may be performed based on information from this detection device.
