DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rocking sorter for a threshing machine mounted on a traveling machine body.

[0002]

2. Description of the Related Art Conventionally, in a threshing machine having a processing cylinder attached to the rear of a handling cylinder and having a swinging sorting body erected in a sorting air passage formed below the processing cylinder, By the specific gravity sorting action by the swinging motion of the sorting body back and forth, and the wind sorting action by the sorting wind that blows through the sorting wind path, the treated material is sorted and separated into the first thing, the second thing and impurities such as straw waste, The first thing is dropped on the first gutter and then collected in a paddy tank by a fryer, and the second thing is dropped on the second gutter and returned to the oscillating sorter by the second return cylinder for reselection. It is also known that straw waste is sucked by a suction fan and discharged from a dust outlet at the rear of the machine to the outside of the machine.

[0005] Then, the paddy that has jumped on a chaff sieve (vibrating sieve) for sifting small culm, straw waste, etc., is scattered by the sifting wind that blows through the sifting air path, and is sucked by the suction fan as it is, and the exhaust port of the body is discharged. The rear end (upper end) of the second flow plate, which is obliquely provided at the rear of the rocking sorter, is projected upward to form a wall in order to prevent discharge from the outside of the machine. It is formed.

[0004]

However, as described above, when the chaff that jumps on the chaff sieve (vibrating sieve) collides with the rear end (upper end) of the second flow plate and scatters upward, In many cases, the air is blown through the screening air path and sucked by the suction fan and discharged from the dust outlet at the rear of the machine to the outside of the machine. Also, to improve the above problems,
In the case where the rear end (upper end) of the second flow plate is inclined forward, although the scattering of the paddy due to the collision is reduced, there is a disadvantage that other straw wastes are more likely to catch. Was.

SUMMARY OF THE INVENTION The present invention has been made for the purpose of solving the above-mentioned problems based on the actual situation, and sways in a sorting air passage formed below a handling cylinder. In a threshing machine having a sorting body erected therein, in order to suppress the scattering of paddy colliding with the rear end of the second flow plate obliquely provided at the rear of the swinging sorting body, at the rear end of the second flow plate It is characterized by attaching a buffer member.

[0006]

An embodiment of the present invention will be described with reference to the drawings. In FIG. 1, reference numeral 1 denotes a threshing machine mounted on a traveling body (not shown), which stretches a feed chain 3 in a front-rear direction along a handling room 2 formed in the threshing machine 1. A straw transporting band 4 is continuously provided at the end of the stalk, and the culm after threshing in the handling room 2 is transported to a culm disposal device (cutter) 5 disposed at the rear of the traveling machine.

The threshing machine 1 comprises a handling cylinder 2 forming a handling chamber 2.
A processing chamber 6 in which a processing drum 6a and a processing net 6b are provided is provided adjacent to the end of the processing net 6a and the handling net 2b. Below these, a corrugated non-porous transfer plate 7a and a variable opening chief sheave 8, and a non-porous transfer plate 7b below the chaff sheave 8 are disposed. The filter body 9 is stretched rearward from the portion, and the lowermost flow plate 11 for letting the first thing flow down to the first gutter 10 is obliquely provided below the filter body 9 and the rear end portion of the first flow plate 11 A plurality of straw racks 12 are protruded, and a second flow plate 14 for allowing a second object to flow down to a second gutter 13 is provided obliquely below the straw racks 12 to form a swing sorter 15 integrally framed with them. ing. And, the rocking sorting body 15
Is the support link 16 and the drive mechanism (link) 1
7 detachably supported by a swing support mechanism composed of
The assembly and insertion / removal work of the swing sorting body 15 can be easily performed.

[0008] Further, below the swinging sorting body 15, there is formed a sorting air path 19 composed of Karamin 18 and the first flow plate 11, etc., and sorting from below facing the swinging swinging body 15 which swings. The first item is selected by the wind A, and the second item on the straw rack 12 is selected by the sorting wind B sent from the auxiliary Karino 20 disposed behind the sorting air passage 19. Further, the separated and separated impurities are discharged through a suction fan 21 from a dust outlet 22 at the rear of the machine to the outside of the machine. Note that the paddy that has fallen into the first gutter 10 is lifted and conveyed to a grain tank (not shown) by the frying cylinder 23, and the second gutter 1
The second product that has fallen to 3 is returned to the swing sorting body 15 via the second return cylinder 24.

As shown in FIG. 2, the rear end (upper end) 14a of the second flow plate 14 which is conventionally provided obliquely at the rear of the swinging sorter 15 projects upward in a wall shape. Let me do it. That is, according to the above-mentioned shape, the paddy which jumps on the chaff sieve (vibrating sieve) 8 for sifting small culm, straw waste, etc., is scattered by the sifting wind blowing through the sifting air path, and is sucked by the suction fan 21 as it is, and This is intended to prevent the dust from being discharged from the exhaust port 22 to the outside of the apparatus. However, as shown in FIG. 2, when the chaff that jumps on the chaff sieve (vibrating sieve) 8 collides with the rear end (upper end) 14 a of the second flow plate 14 and jumps upward,
In some cases, the paddy was sucked by the sorting wind that blows through the sorting wind path and the suction fan 21, and was discharged to the outside of the machine from the dust outlet 22 at the rear of the machine.

However, in the present invention, as shown in FIG. 3, inside the rear end (upper end) 14a of the second flow plate 14,
By sticking the buffer member 30 for suppressing the rebound (scattering) due to the collision of the paddy using an adhesive or a double-sided adhesive tape or the like, the paddy that jumps on the chaff sheave (vibrating sieve) 8 becomes the buffer member. Even when the paddle 30 collides with the buffer member 30, the paddy does not greatly jump upward, and the paddy that has collided with the buffer member 30 falls as it is and flows down along the second flow plate 14. Therefore, the paddy that has collided with the buffer member 30 is sucked by the sorting wind that blows through the sorting wind path and the suction fan 21, and is not discharged outside from the dust outlet 22 behind the machine.

The cushioning member 30 used in the present invention has elasticity such that when the paddy collides, the cushioning member 30 absorbs the collision energy of the paddy while distorting in the collision direction of the paddy, and subsequently substantially recovers the original state. If so, the material is not particularly limited. Specifically, urethane foam, styrene-
Examples thereof include polymer foams such as butadiene rubber (SBR) foam and polyvinyl acetal sponge, and soft rubber. Further, a buffer effect may be obtained by using a fiber such as a nonwoven fabric, a woven fabric, or a knitted fabric. Then, the cross section of the cushioning member 30 may be formed so as to have an internal hole 30a as shown in FIG. 4, so that a cushioning effect like an air cushion may be obtained.

In this embodiment, the cushioning member 30 is adhered to the inside of the rear end (upper end) 14a of the second flow plate 14. The rice colliding with the plate 14 hardly jumps upward. Further, the rear end (upper end) 14a of the second flow plate 14 itself may be formed by the buffer member 30. In this case, the buffer member 30 can be screwed to the end of the second flow plate 14. It is good if it is constituted.

[0013]

According to the present invention, as described above, the swing sorter 1
The rear end (upper end) of the second flow plate 14 slantingly provided at the rear of 5
By attaching the buffer member 30 for suppressing the rebound (scattering) due to the collision of the paddy to 14a, the paddy that has jumped on the chaff sieve (vibrating sieve) 8 is attached to the buffer member 30.
Therefore, the paddy that collides with the cushioning member 30 falls as it is and flows down along the second flow plate 14. Therefore, the paddy that has collided with the buffer member 30 is sucked by the sorting wind that blows through the sorting wind path and the suction fan 21, and is not discharged outside from the dust outlet 22 behind the machine.
