Description

Detailed Description of the Invention [Industrial Field of Application] The present invention provides a method in which a sorting cylinder is horizontally mounted almost perpendicular to the direction of transfer of the processed materials discharged from a handling chamber, and the sorting cylinder is sorted along the lower side of the sorting cylinder. The present invention relates to a sorting section structure of a thresher that is provided with a screen and configured such that the processed material passes between the sorting cylinder and the screen.

[Conventional technology]

The structure of the sorting section of this type of threshing machine is
As disclosed in Publication No. 55-149329, a drum-shaped sorting cylinder is mounted on a shaft in the width direction of the machine at the rear of the handling room, and a plurality of processing units are individually installed on the outer circumferential surface of this sorting cylinder. The processed material discharged from the handling chamber is threshed again by the teeth, and the single grains leak through the lower sorting net, and the remaining processed material is sent backwards as the handling teeth rotate. What I did was hot.

[Problem that the invention seeks to solve]

However, since the processing teeth of the sorting cylinder mentioned above are a single small member, even when the sorting cylinder rotates, it simply moves in a circular trajectory, and does not impact the material to make it into single particles. However, for backward feeding, it was only possible to apply linear movement force back and forth along the feeding direction. Therefore, the tangled processed material could not be effectively sorted, and the paddy could not be made into single grains or leaked sufficiently.

The present invention was devised by paying attention to such a situation, and the purpose of the first invention is to improve the effect of cutting, and the purpose of the second invention is to improve the effect of cutting and at the same time to improve the effect of cutting. The aim is to further promote the development of

[Means for Solving the Problems] A characteristic configuration of the first invention is that a plurality of disks are fitted and fixed on the outer periphery of the sorting cylinder in a state inclined with respect to the axis of the sorting cylinder. , the characteristic configuration of the second invention is that a plurality of disks are externally fitted and fixed to the outer periphery of the sorting cylinder in a state inclined with respect to the axis of the sorting cylinder, and the disks are made into a substantially perfect circle when viewed in the direction of the axis. , in that a protrusion is provided on its outer periphery.

[Effect]

According to the configuration of the first invention, since the disk externally fitted and fixed to the sorting cylinder is inclined, as the sorting cylinder rotates, the outer circumference of the disk swings in the direction of the axis of the sorting cylinder. Therefore, the outer periphery of the disk can apply not only a linear movement force along the feeding direction to the processed material, but also a biasing force in the direction of the axis of the sorting cylinder, and the processed material can be moved onto the sorting net. It is effectively broken down, making it easier to form single grains and leak.

According to the configuration of the second invention, the following effects are added to the effects of the first invention. In other words, since the outer shape of the tilted disk is almost a perfect circle when viewed in the axial direction, if the sorting net is placed along it, the distance between the outer periphery and the sorting net will be maintained even when the disk rotates. You can always maintain the optimal distance. Further, since the protrusion is provided on the outer periphery, it is further promoted to make the shredded material into single grains.

〔Effect of the invention〕

As a result, according to the first aspect of the present invention, even entangled processed materials can be effectively separated, and the single graining and leakage efficiency are improved. Furthermore, the second invention adds the following effects to the first invention. In other words,
The distance between the outer periphery of the disk and the sorting net is maintained at an optimum distance to eliminate unevenness in threshing, and the protrusions on the outer periphery work effectively to further improve the single graining effect.

The threshing section B includes a handling chamber 6 formed in the upper part of the machine.
A handling cylinder 5 is mounted on a shaft extending from the left and right sides of the cylinder, and a concave 8 is arranged below the cylinder. Then, it is lifted and conveyed by the rotary cylinder 4B at the rear.
After essentially handling and processing the grain culm sent from the terminal end of the
It is returned above B and reprocessed together with the grain culms that are being transported. Here, the processed material that has leaked out of the concave 7 falls into the front part of the grain pan 9, which is one of the sorting sections C, and the actual processed material that has not leaked is in the beater 10.
It is discharged to the rear by

The sorting section C includes a grenpan 9 which swings and transfers the leaked materials rearward while sorting the leaked materials from the concave 7 and 8 based on the difference in specific gravity, and a beater 10 which re-handles and processes the non-leakable materials discharged by the beater 10. The four sorting cylinders 12A, 12B, 12C, and 12D, and the swinging motion that sorts the processed materials sent from the grain pan 9 and the sorting cylinders 12A to 12D into three types: first material, second material, and straw waste. It is configured to include a sorting device 13. The sorting cylinders 12A to 12D are drum-shaped and rotate counterclockwise in the figure around left and right horizontal axes, and a series of sorting nets 14 are disposed below them.
The leaked material that has leaked into the sorting net 14 is caught on the swinging flow plate 15 and guided forward to flow down.

is provided.

Next, the sorting cylinders 12A to 12D will be explained.

As shown in FIG. 2, the sorting cylinders 12A to 12D are mounted on shafts in the width direction of the machine body, and a plurality of discs 22 are arranged on the outer periphery at equal intervals and in the direction of the axis P of the sorting cylinders. This disk 22, which is externally fitted and fixed with an angle of θ, has an elliptical shape with a protrusion 22a on the outer periphery, and when viewed in the direction of the sorting cylinder axis P, it becomes almost a perfect circle due to its inclination ( (See Figure 1). The sorting nets 12A to 12D are provided along this perfect circle.

When the sorting cylinders 12A to 12D rotate, the inclination of the disk 22 causes its outer peripheral portion to swing left and right in the direction of the sorting cylinder axis P. Specifically, if the major axis of the disk 22 is 2R, the outer circumference shifts within a range of 2Rcosθ in one rotation. Disk 22
The interval is set narrower than this 2Rcosθ,
When the sorting cylinders 12A to 12D rotate once, the sorting net 1
The action of the disk 22 is adapted to be applied to all the objects to be processed on the disk 4.

Therefore, when the processed material discharged from the handling chamber 6 by the war beater 10 is supplied between the sorting cylinders 12A to 12D and the sorting net 14, the protrusion 22 of the disk 22
A blow is applied to the grains to make them into single grains, and the grains are swung from side to side to be separated and transported to the rear. Therefore, the grains in the processed material are efficiently made into single grains, and the leakage of the crushed grains of the processed material is also promoted, resulting in high recovery efficiency.

In carrying out the present invention, the sorting barrel may be provided at the rear of the handling chamber 6 of the self-extracting combine harvester.
