Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a swing sorting case for transporting and sorting a processed material from a handling chamber as it is driven and swinged, and a chaff sheave formed by arranging a number of chaff plates in parallel in the processed material transport direction. The present invention relates to a combine combine threshing device.

[0002]

2. Description of the Related Art Conventionally, chaff sheaves have been designed so that the leakage angle can be adjusted by changing the angle of inclination of the chaff plate. The other components such as the above are integrally driven and oscillated to simply make an elliptic motion.

[0003]

However, when the treated product is so wet that the grain culms harvested after early morning or after rain are targeted, the chaff plate is clogged due to adhesion of the treated product to the chaff plate, Grains were prevented from falling and the efficiency of grain recovery was likely to drop, and there was room for further improvement in terms of improving sorting performance. An object of the present invention is to make it possible to effectively prevent clogging of a treated product with a chaff sieve even if the treated product is severely wet.

[0004]

A characteristic configuration of the present invention is that a plurality of chaff plates are arranged in parallel in a processing object transfer direction in a swing selection case for transferring and selecting a processing object from a handling chamber according to a drive swing. In the combine threshing device provided with the chaff sheave, the chaff sheave is reciprocally attached to the rocking sorting case by the drive device at a cycle shorter than the reciprocating cycle of the rocking sorting case.

[0005]

In other words, the movement of the chaff sheave is complicated by the combined movement of the elliptic movement of the chaff sheave accompanying the original drive swing of the swing sorting case and the driving reciprocating movement of the chaf sheave with respect to the swing sorting case. Along with the complicated movement, it is possible to generate an accelerating force for peeling the adhered matter from the chaff sheave in various directions, thereby making it difficult for the treated matter to adhere to the chaff sheave, and
It is possible to make it easier for the adhered processed material to separate from the chaff sieve, and even if the processed material is extremely wet, it is possible to reliably prevent clogging of the chaf sieve due to adhesion of the processed material to the chaff sieve, and improve grain collection efficiency. Sufficient and surely improved.

[0006]

As a result, even if wet culms such as those in the early morning or after rain are to be treated, it is possible to effectively prevent clogging of the treated products in the chaff sheaves, which is a more excellent combine in terms of harvesting conditions and sorting performance. Is now available.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in FIG. 1, a mowing section 2 is provided at the front part of a traveling vehicle equipped with a crawler type traveling device 1 so that it can be moved up and down by swinging around a support shaft 4 by a hydraulic cylinder 3 to mow it. The section 2 is provided with a planted grain culm raising device 5, a cutting blade 6, and a conveying device 8 that sends the cut grain culm to the threshing device 7, and supplies the grain culm from the reaping part 2 to the threshing device 7 while conveying it backward. A feed hopper 9 is provided, and a bag-filling hopper 11 that collects the first grain (grain) that has been threshed and sorted by the threshing device 7 is arranged on the side of the threshing device 7, and boarding operation is performed in front of this hopper 11. The parts 12 are arranged to constitute a self-removing combine.

The threshing device 7 is constructed as shown in FIG. That is, the handling cylinder 14 is provided in the handling chamber 13 so as to be rotatable about the lateral axis in the longitudinal direction of the machine body, and the receiving net 15 arranged along the lower portion of the handling chamber 13 is integrally formed of resin into a porous plate shape. It is configured so that the chaffed rice and the wet treated material do not easily adhere to the receiving net 15. In the sorting section 10 provided from the lower side to the rear side of the handling room 13, a swing sorting case 16, a wind picking sardine 17, a 1st thing recovery screw conveyor 19, a 2nd thing recovery screw conveyor 20, a handling room 13 end. A diffusion drum 21 that loosens the processed material sent from the machine and collects the mixed rice paddy, and an air exhauster 22 that sucks and discharges the floating dust in the sorting unit 10, and the processed material and the handling chamber 13 that have leaked the net 15
The processed product sent out from the terminal end is subjected to sieving and wind-selection processing while being conveyed backward by the rocking and sorting case 16, and the grain is fed to the hopper 11 by the No. 1 object recovery screw conveyor 19 and the screw-type lifting conveyor 23. The second product that has been insufficiently sorted is returned to the front part of the rocking sorting case 16 by the second item recovery screw conveyor 20 and the screw type reduction conveyor 24 to be sorted again. The swing pan 16 has a Glen pan 26, a rough selection chaff sheave 27 connected to the rear side of the swing pan, and a precise selection Glen pan 28 and a Glen sieve 2 located below the chaff sheave 27.
9, a Straw rack 32 with a Glen pan 31 for receiving a processed material from the dust delivery port 30 of the handling chamber 13, and a Straw rack 33 connected to the rear side of the chaff sheave 27 are provided.

As shown in FIG. 3, the rollers 16a provided on the left and right of the front end of the rocking / sorting case 16 are supported by guides 18 fixed to the left and right side plates of the threshing device 7 so as to be reciprocally movable in the inclination direction, and driven and rotated. Eccentric crank 25
The rear end side of the swing selection case 16 is connected to the front end side of the swing selection case 16, and the front end side of the swing selection case 16 linearly reciprocates, the middle part of the front and rear makes an elliptical motion, and the rear end side makes a circular motion. ..
The cheaf sheave 27 has a large number of inclined chaff plates 3.
4 are arranged side by side in the processing object conveying direction, and the left and right support frames 35 are provided.
The chaff sheave 27 is installed between the sheave case main body 16a and the chaff sheave 27.
Then, the support frame 3 in the chaff sheave 27
The roller 35a provided on the front end side of
An eccentric crank 38 which is supported by guides 36 fixed to the left and right side walls of the support frame so as to be linearly reciprocally movable in the inclination direction, and the rear end side of the support frame 35 is driven and rotated by an electric motor 37.
Therefore, the chaff sheave 27 is configured so that the front end side linearly reciprocates, the front-rear intermediate part makes an elliptical motion, and the rear end side makes a circular motion at a shorter cycle than the swing selection case 16. By combining the reciprocating motion of the dynamic sorting case 16 and the reciprocating motion of the chaff sheave 27 with respect to the oscillating sorting case 16, the chaff sheave 27 moves in a complicated manner, and the complex movement imparts an accelerating force to the chaff sheave 27 in various directions. When the chaff plate 3 is generated, the acceleration force suppresses the adherence of the processed material to the chaff plate 34.
The processed material adhered to No. 4 is easily peeled off.

[Other Embodiments] It should be noted that the chaff plate 34 may be changed in angle so that the leakage fit can be adjusted.
When the chaff sheave 27 is reciprocally attached to the swing selection case 16, the attachment structure, movement method, drive means, etc. can be freely changed, and these drive configurations are collectively referred to as a drive device 37.

It should be noted that although reference numerals are given in the claims for convenience of comparison with the drawings, the present invention is not limited to the configuration of the accompanying drawings by the entry.
