Description

[Detailed description of the invention] (Field of industrial application) This invention relates to a threshing machine for threshing and sorting grains.

(Prior Art) The second item collected by the second item collection device is returned to a handling room or to a sorting shelf that sorts leaked items that have leaked from a receiving net in the handling room.

(Problem to be solved by this invention) However, in the first configuration, newly threshed grains and second grains are processed in the handling chamber, which increases the load on the handling drum and results in a large number of unprocessed items. Loss occurs due to particle size mixing in waste materials. In addition, in the second configuration, since unprocessed substances are mixed in with the grains leaking from the receiving net, these unprocessed substances cause a failure in the separation of grains and foreign substances, causing the grains to be sent to the first collection section. This may impede collection.

(Means for Solving the Problems) This invention provides a threshing machine that can prevent damage and poor sorting, and takes the following technical measures.

That is, a first item collection section 2 and a second item collection section 3 are arranged in front and back at the bottom of the sorting chamber 1, and one end of this is placed between the first item collection section 2 and the second item collection section 3. A sorting belt 5 is rotatably provided, which communicates with the first object collecting section 2 and the other end communicates with the second object collecting section 3 and moves the conveyance side section 4 toward the rear and diagonally upward. to 2
A second product hoisting device 6 for frying the second product collected by the second product collection unit 3 is provided, and a discharge port 7 for the second product fried by the second product hoisting device 6 and the sorting belt The threshing machine has a structure in which a sorting shelf 8 swingable in the front and back direction and capable of sifting objects to be sorted onto a lower sorting belt 5 is installed in a space between the grains.

(Function) Among the fallen objects that have fallen onto the sorting belt 5, grains with low frictional resistance are flowed downward and collected in the No. 1 item collecting section 2, while No. 2 items with high frictional resistance are conveyed diagonally upward. It falls from the end of this conveyance and is collected by the second item collection section 3. The second product (unprocessed) collected by the second product collection unit 3 is fried by a grain frying device 6 and supplied to a sorting shelf 8 from a discharge port 7. Among the leakage materials leaked from the swinging sorting shelf 8, light dust is discharged outside the machine, but heavy grains are collected in the No. 1 material collection section 2. Further, the unprocessed materials are transported by the sorting belt 5 to the second product collection section 3 side, and then supplied to the sorting shelf 8 again via the second product collection section 3 and the grain frying device 6.

(Effect) Since a circulation path for the second product is formed between the sorting belt 5, the second product collection section 3, the grain frying device 6, and the sorting shelf 8, the second product is transported to the impact area of the handling room, etc. will not be reduced to Therefore, since the impact applied to the second item is small, no damage is caused and the quality can be improved. In addition, especially when the material to be sorted has good rolling properties such as soybeans, the sorting belt is rotated diagonally upward toward the rear on the second material collection section side.
The No. 1 item will fall to the No. 1 item collection section side, and the No. 2 item will be actively lifted up to the No. 2 item collection section side to be returned, and a reliable and good sorting effect can be expected.

(Example) Hereinafter, an example of this invention will be described in detail based on the drawings.

It communicates with the sorting chamber 1 via a dust exhaust port 22. At the bottom of the sorting chamber 1, a winch 23, a first item collection section 2, and a second item collection section 3 are provided from the front side.

The sorting belt 5 is rotatably provided so that one end communicates with the first item collection section 2 and the other end communicates with the second item collection section 3 so that the conveying side section 4 moves rearward and obliquely upward. In addition, the left and right widths are slightly smaller than the inner widths of the left and right side walls of the sorting chamber 1. In addition, there is another 1
The first article collecting section 2a and one end of the first article collecting section 2a.
A sorting belt 5a is provided, which communicates with the sorting belt 5a and has its other end located above one end of the sorting belt 5 via the first item collecting section 2. The conveying section located above the sorting belt 5a is the first item collecting section 2a.
It is configured to be rotatable so as to move from the side toward the sorting belt 5 side.

The grain hoisting device 6 is a bucket-type elevator built into a grain hoisting case 25 so that buckets 24 installed at predetermined intervals can be moved vertically.
It is removably attached to the horizontal outer wall of 2. and,
The grain frying device 6 transfers the starting end of the grains to the second grain collecting section 3.
The conveyance start end of the grains is communicated with, and the fried grain end is communicated with a discharge funnel 26 whose discharge port 7 communicates with the sorting chamber 1. Note that the second object collection section 3 is open to communicate with the outside of the machine.

The sorting shelf 8 has a conveyance start end located below the dust exhaust port 22, an intermediate portion that communicates with the discharge port 7, and a conveyance end portion located above the second item collecting section 3 so as to extend in the front-rear direction. It is designed to be swingable. In addition, sorting shelf 8
The conveyance terminal end is slanted to be located above the sorting start end and communicates with the outside of the machine.
Further, the sorting shelf 8 is provided with a leakage hole (not shown) through which grains and unprocessed grains can leak, and a dust exhaust port 2 is provided.
A protrusion 27 is provided that can move the waste discharged from the discharge port 2 and the reduced material supplied from the discharge port 7 to the conveyance terminal side.

Reference numeral 28 denotes a transfer and sorting shelf which is equipped with a transfer shelf 29 and a sorting net 30 and is swingable in the front and back direction.
0 is located in the space between the sorting belt 5a and the sorting shelf 8. Further, the grains leaking from the sorting net 30 are configured to fall onto the first grain collecting section 2a and the sorting belt 5a.

Reference numeral 31 denotes the first grain hoisting device in which buckets 32 installed at predetermined intervals can be moved vertically inside the hoisting case 33, and are removably installed on the outer wall on the side of the machine. The first part is connected to the conveyance terminal end of the first product collecting part 2, 2a, and the fried grain terminal end is connected to the grain storage tank 34.

Next, the operation will be explained. After starting the prime mover and driving each rotating part of the machine body, the operating device 13 is operated to move the machine body forward and start work.
Then, the leguminous plant (soybeans in this embodiment) harvested and transported by the harvesting and transporting device 11 is fed into the handling chamber 15 through the supply port 21 and threshed by the handling cylinder 17 rotating in the direction of the arrow. Then, the transfer shelf 29 of the transfer sorting shelf 28 swings back and forth from the leakage net 19.
The leaked material that has leaked upward is transferred to the sorting screen 30, but the threshed grain that has not leaked is sent into the dust removal chamber 16 through the communication port 14. The dust discharged from the dust exhaust port 22 by the dust exhaust cylinder 18 falls on the sorting start end of the sorting shelf 8 and is conveyed to the conveyance end side by the protrusion 27, but leaks from the leakage net 20. The leakage material falls onto the screening screen 30. Note that some of the leakage material leaked from the leakage net 20 may fall onto the sorting start end of the sorting shelf 8. Leakage that leaks from the leakage hole while being transported on the sorting shelf 8 falls onto the sorting net 30 at the starting end of sorting, and falls onto the conveying side part 4 of the sorting belts 5, 5a at the middle part of sorting. However, at the end of the conveyance, it falls into the second object collecting section 3, but the culms, pods, etc. that have not leaked are discharged from the machine from the end of the conveyance. Then, the single grains directly fallen from the sorting net 30 and the sorting belt 5 are collected from the sorting net 30 and the sorting shelf 8.
The single grains that have fallen onto the surface a are collected by the first grain collection section 2a, but light pods, culm chips, dust, etc. are discharged out of the machine by the pressure of the winch 23. On the other hand, sorting net 3
The grains with pods that have fallen from the end of the zero and the sorting shelf 8 onto the sorting belt 5a are conveyed to the sorting belt 5 by this sorting belt 5a and the pressure air, and are then separated from the grains with pods that have fallen from the sorting shelf 8 and the sorting belt 5a. Belt 5a
The grains with pods that have been transported from there are transported backward by the sorting belt 5, and then supplied to the second item collection section 3 from the end of the transport. In addition, the single grains that have fallen from the sorting shelf 8 and some of the single grains that have been conveyed by the sorting belt 5a are collected by the first item collecting section 2 after flowing through the sorting belt 5. Therefore, the single grains collected by the first grain collecting sections 2 and 2a are conveyed to one side, and then fried by the first grain hoisting device 31 and sent to the grain storage tank 34. Incidentally, the light pods and culms on the sorting net 30 and the light pods, culms and dust falling from the sorting shelf 8 are discharged out of the machine by the pressure of the winch 23. Then, the grains with pods supplied by the sorting belt 5 and the grains with pods that have fallen from the sorting shelf 8 are transported to one side of the second material collecting section 3, and then fried in the bucket 24 of the grain lifting device 6 and sent to the discharge funnel. 26
The liquid is supplied from the discharge port 7 to the sorting shelf 8 via the outlet 7. Then, the dust is re-sorted on the sorting shelf 8 which swings together with the dust supplied from the dust outlet 22 and transported. Incidentally, the single grains mixed in the grains with pods are also fried by the grain frying device 6, and supplied from the discharge port 7 to the sorting rack 8, where they are subjected to a re-sorting action. The single grains leaking from the sorting shelf 8 are collected by the first grain collecting sections 2 and 2a, but the grains with pods are also conveyed to the second grain collecting section 3 by the sorting belt 5 and then transferred to the grain frying device 6. and is supplied to the sorting shelf 8 via the discharge funnel 26.

In this way, since the grains with pods and some of the single grains are not returned to the impact part (for example, the handling chamber 15 or the dust removal chamber 16), it is possible to prevent the generation of damaged grains. In addition, while the grains with pods are conveyed by the sorting belts 5, 5a, the grains with pods flow down and the sorting belts 5, 5a
The pods can also be removed from the grain by friction between the conveying action of Further, the pods can be removed while the grains with pods circulate through the sorting belt 5, the second grain collecting section 3, the grain frying device 6, and the sorting rack 8. Therefore, while removing the pods, the generation of damaged grains can be prevented and quality can be improved. In addition, although the case has been described in which the present invention is applied to a harvester that harvests by moving its body, it can also be applied to a mobile threshing machine or a stationary threshing machine.
