Description

[Detailed Description of the Invention] This invention relates to an improvement of a pulse threshing machine that takes out the beans by threshing the beans, such as soybeans, harvested with branches attached.

Unlike threshing of rice, wheat, etc., pulse threshing machines feed soybeans, etc., which are harvested with branches attached, into the threshing chamber of the threshing machine for processing. A large amount of waste will be generated. Therefore, in order to efficiently sort these large amounts of processed materials and beans, it is possible to solve the problem by lengthening the processing process like a thresholder type, but on the other hand, the problem is that the machine becomes larger accordingly. will also wake up. Therefore, the purpose of this invention is to make the size of the machine body almost the same as a threshing device for threshing rice, wheat, etc., and to shorten the processing process and perform efficient sorting.

To specifically describe the embodiment based on the drawings, 1 consists of a sorting shelf 10 arranged across the front and back of the machine body a of the threshing machine A (in the left-right direction in the drawing) and a feeding shelf 11 arranged below it. On the swinging sorting shelf, link rod 12 is moved so that it swings back and forth (arrows A and B)...
It is mounted in the internal cavity of the aircraft body a. Swing sorting shelf 1
The upper sorting shelf 10 has a large number of through holes 10 formed on its shelf surface to a size that allows the beans to pass through easily.
A... is provided, and by swinging back and forth, both the processed materials such as branches, leaves, shells, etc. and the beans are conveyed backwards (arrow A), and only the beans are allowed to fall downward from the aforementioned through hole 10a. It acts to send it backwards. Further, the lower-side feeding shelf 11 is the sorting shelf 1
It works to send out the beans and small processed materials that have fallen from the zero point to the rear (arrow A) together.
It is made of blind boards with a mountain-shaped cross section. Reference numeral 2 denotes a threshing chamber provided above the starting end side 1a of the swing sorting shelf 1. A part of the bottom wall 20 of the blind plate is opened, and the opening is formed into a discharge culm opening 21. Dynamic sorting shelf 1
It is directed toward the starting end 1a side. Inside the threshing chamber 2,
A pair of grain removal rolls 23, 23, which rotate counter to each other in the direction of the arrow with a circumferential speed difference, are mounted vertically on a shaft facing the supply port 22 provided on the front side of the machine body a (on the right side of the drawing). - At the inside position of 23, there is mounted a shaft for housing a grain removal cylinder 24 whose lower peripheral side rotates along the bottom wall 20 of the grain removal chamber 2 toward the rear surface of the machine a (arrow C). The sloughing rolls 23 in the sloughing chamber 2 have a material 23 with a large friction coefficient such as rubber on their circumferential surfaces.
a.23a is installed, and is driven with a difference in circumferential speed so that the circumferential speed of the upper shedding roll 23 is faster than the circumferential speed of the lower shedding roll 23. When the grain culms supplied from the above-mentioned supply port 22 are clamped and fed into the machine,
It works by crushing the husks attached to the grain culms and threshing out the beans.

In the illustrated embodiment, the respective rotating shafts 25, 25 of the grain removing rolls 23, 23 are pivotally supported on the machine body a with their positions fixed, but the rotating shaft 25 of the upper grain removing roll 23 is Lower side threshing roll 2
The grain culm is pivoted on the machine body a so as to be able to move forward and backward with respect to the rotating shaft 25 of No. 3, and a spring is applied to push it toward the threshing roll 23 on the lower side, thereby increasing the clamping pressure of the grain culm in the opposing gap while facing the grain culm. The gap may be expanded or contracted depending on the amount of grain culm supplied, and these threshing rolls 23, 23
The above-mentioned circumferential speed difference set at Although it is set to rotate at a difference in circumferential speed, when the removing rolls 23, 23 are formed to have different diameters, they may be set to rotate at a difference in circumferential speed caused by the different diameters.

Further, the grain removal cylinder 24 is connected to a prime mover (not shown) via an appropriate transmission mechanism and is supported by radial mounting arms on the left and right shaft ends of the grain removal cylinder shaft 26, which is supported so as to rotate in the direction of arrow C. 27 (the front side of the drawing is omitted) is attached, and a rod-like toothed rod 28 is suspended between the mounting arms 27. The beans are threshed by hitting the grain culms, and the residual culms and the shattered beans are discharged from the culm opening 21 toward the starting end 1a of the swing sorting shelf 1. Note that the presser plate 29 provided in the threshing chamber 2 functions to press down from above so that the grain culms sent to the threshing drum 24 side by the rolls 23 are hit efficiently when the threshing drum 24 hits them. Something,
It is attached to the rear side of the threshing rolls 23. 3 is a Karaoke blower installed below the swinging sorting shelf 1, and the sorting air is directed to the rear side of the machine a (left side in the drawing).
The air outlet 30 of the air outlet 30 is opened rearward so as to blow air toward the air. Further, below the terminal end side 1b of the swing sorting shelf 1, there is a first receiving gutter 4 for taking out pulses out of the machine, a starting end side 5a faces the first receiving gutter 4, and a terminal end side 5.
A sorting belt 5 is provided which is inclined toward the rear surface (left side in the drawing) of the machine body a. The first receiving gutter 4 has a screw conveyor 40 for loading at the bottom of the receiving gutter 4.
It acts to convey the beans falling into the receiving gutter 4 toward one side. In addition, the sorting belt 5 rotates in the direction of the arrow so that the conveying belt 52 is endlessly wrapped around a driving wheel 50 and an idler wheel 51 arranged at the ascending end and the descending end so that the upper surface side becomes the conveying surface. This acts to roll down the beans that have fallen onto the conveying surface. Then, the upper side sorting air, which is vertically divided between the upper surface side and the lower surface side of the conveyor belt 5 by the air splitter 31 provided at the air outlet 30 of the Karakin blower 3, passes through the upper surface side of the belt 5. A sorting air passage 6 is formed to pass out of the machine, and a sorting air passage 7 is formed, through which the lower side sorting air passes through the lower surface of the belt 5 to the outside of the machine.
A sorting air passage 6 passing through the upper surface side of the sorting belt 5 blows sorting air at the objects to be treated such as branches, leaves, shells, etc. that are sent out from the terminal end 10b of the sorting shelf 10 and falls to the through holes 1.
It acts so that the processed material is blown out of the machine from the dust exhaust port 8 opened at the rear of the machine body a, leaving only the particles that have not passed through the machine body a. Further, the sorting air passage 7 passing through the lower surface side of the sorting belt 5 is formed by the sorting air passage 6
When the small debris that has not been completely air-selected falls from the starting end 5a of the sorting belt 5 into the receiving gutter 4, the debris is removed from the dust outlet 8 opened at the rear of the machine a.
It works to blow more air out of the aircraft. Note that 9 is a supply gutter connected to the supply port 22.

Next, to explain the function and effect, the pulse threshing machine of this invention has a large number of through holes 10a for permeation of the pulses.
A swinging sorting shelf 1 consisting of a sorting shelf 10 provided with... and a feeding shelf 11 made of blind plates arranged below it is arranged across the front and back of the machine a, and swings back and forth. The swing sorting shelf 1 is installed in the internal cavity of the aircraft body a.
Above the starting end side 1a of the machine, there is installed a sloughing chamber 2 in which a culm discharge port 21 is opened on the starting end side of the swing sorting shelf 1, and inside the sloughing chamber 2, there is a A pair of shedding rolls 23, 23 that rotate oppositely with a circumferential speed difference are mounted on a shaft at a portion facing the supply port 22, and at an inner position of the shedding rolls 23, 23,
A grain removal cylinder 24 whose lower peripheral side is along the bottom wall 20 of the grain removal chamber 2 and rotates toward the rear of the machine a is mounted on a housing shaft, and below the swing sorting shelf 1, a sorting air is blown toward the rear of the machine a. A Karachi blower 3 is provided, and a first receiving gutter 4 is provided below the terminal end side 1b of the swing sorting shelf 1, and a starting end side 5a faces the first receiving gutter 4 and the terminal end side 5b faces toward the rear of the machine a. A tilted endless sorting belt 5 is provided, and sorting air passages 6 and 7 are provided on the upper and lower sides of the sorting belt 5 through which the sorting air passes through the upper and lower sides of the belt 5 to the outside of the machine. Therefore, the processed material residue and beans that have been processed in the threshing chamber 2 fall to the starting end side of the sorting shelf 10 of the swinging sorting shelf 1, and while being sent backwards (arrow A), the beans are transparent. The material to be processed passes through the hole 10a, is sent backward (indicated by an arrow) on the upper surface of the shelf, is exposed to the sorting air in the sorting air passage 6, and is discharged from the dust outlet 8 to the outside of the machine. Furthermore, the beans that have passed through the sorting shelf 10 are sent rearward (indicated by the arrow) toward the first receiving gutter 4 by the feeding shelf 11. At this time, the small particles mixed in with the grains are exposed to the sorting air from the lower sorting air passage 7 and are discharged out of the machine.

In particular, threshing of beans involves threshing (threshing) and removing (sorting) the large-sized beans, so unlike normal threshing of rice and wheat, large-sized beans are
It has the property of quickly rolling down slopes.

Therefore, the beans that cannot be completely sorted on the sorting shelf 10 and are sent to the terminal end side 1b can be dropped downward by the inclined sorting belt 5.
This has the advantage that efficient sorting can be performed without lengthening the processing process, and the machine can be made approximately the same size as a conventional threshing machine.
