Description

[Detailed description of the invention] The present invention is a threshing device that is equipped with a processing chamber in addition to a handling chamber in order to increase the threshing capacity. A processing chamber with an interior is provided in such a manner that the direction of transfer of the processed material by the processing chamber is the same or almost the same as the direction of transfer of the processed material by the handling chamber, and a discharge port is formed at the transfer end of the processing chamber, A second material reducing device is provided in the upper space of the processing cylinder of the processing chamber to scatter and supply the second material from the transfer end portion toward the transfer start end side, and
The present invention relates to a threshing device that is provided with a communication port for supplying the processed material, which has been transferred to an intermediate portion of the processing chamber in the transfer direction, to an intermediate portion of the processing chamber in the transfer direction using a rotational action of a processing cylinder.

Such a threshing device uses the scattering and supplying action of the second material into the processing chamber, so that the heavier the second material, which contains more grains and twig stalks, is flown to the upper side in the direction of transport of the processed material without stalling. The upper side and the lower side in the direction of conveyance of the processed material with respect to the opening are used to process the second material containing a large amount of grains and twig stalks and the second material containing a small amount of grain and twig stalks separately. The workpiece processed on the upper side in the object transfer direction is supplied into the handling chamber through the communication port, thereby reducing the processing load on the downstream side in the workpiece transfer direction than the communication port, and
This system is designed to improve the processing performance of the second material in the processing chamber, but unlike the conventional method, the upper part of the processing cylinder has an upper space for reducing the second material over the entire length in the direction of transporting the material. When the opening is opened, the second material supplied to the processing cylinder corresponding to the communication port is not processed in the processing chamber due to the rotational action of the processing cylinder and passes through the communication port in an unprocessed state. There was a drawback that it was supplied inside the handling room.

The purpose of the present invention is to overcome these drawbacks by adding a simple structure.

The threshing device according to the present invention is characterized in that a shielding plate that covers the upper side of the processing barrel is provided in the processing chamber and at least at a location corresponding to the communication port.

In other words, the shielding plate can prevent the second material from being supplied to the processing cylinder portion corresponding to the communication port due to the scattering supply by the second material reducing device. By adding a simple structure, it is possible to prevent the second material that has been scattered and supplied into the processing chamber from being supplied into the processing chamber through the communication port in an unprocessed state, thereby preventing the processing in the processing chamber. By improving the performance and providing a processing room in addition to the handling room, we were able to truly increase the threshing capacity.

In particular, when the shielding plate is constructed with a substantially curved upper surface, it is possible to prevent the scattered supply materials from remaining on the upper surface of the shielding plate, and to clean the inside of the device afterwards. It is advantageous in such situations.

Embodiments of the present invention will be described below based on the drawings.

The threshing device is equipped with a feed chain 2 that clamps and conveys the grain culm to be threshed in a sideways posture in cooperation with the clamping rail 1, and a handling cylinder 3A that acts on the grain culm that is pinched and conveyed by the feed chain 2, and This handling torso 3
A handling chamber 3 and a processing cylinder 4A are installed so that the direction in which the material to be processed (material to be processed) is transported by A is almost the same as the direction in which the material to be processed is conveyed by the feed chain 2. A processing chamber 4 is provided on one side of the handling chamber 3 in such a state that the direction of object transfer is the same as the direction of object transfer by the handling chamber 3, and the falling objects from both chambers 3 and 4 are sorted. a sorting section 5 for sorting, a first article collection section 6 with a carry-out screw 6A for collecting the first sorted article, a second article collection section 7 with a carry-out screw 7A for collecting the second sorted article;

By cutting out the receiving nets 3a, 4a stretched along the receiving nets 3a, 4a, discharge ports 3b, 4b are formed through which the objects to be processed, which are transferred to the transfer end portion without passing through the holes of the receiving nets 3a, 4a, fall. and both chambers 3 and 4
A communication port 9 is provided in the partition wall for supplying the object to be processed, which has been brought to the intermediate portion in the transfer direction within the processing chamber 4, to the intermediate transfer portion within the handling chamber 3 through the rotational action of the processing cylinder 4A.
is formed.

The handling cylinder 3A and the processing cylinder 4A rotate in the same direction, and the handling cylinder 3A and the processing cylinder 4A have a group of handling teeth 3c and a group of processing teeth 4c, respectively, on the peripheral surfaces of the handling cylinder 3A and the processing cylinder 4A.
The group is installed in such a manner that the object to be processed is transferred in the above-mentioned direction as the cylinder rotates. And processing cylinder 4A
On the circumferential surface thereof, blades 4d for scraping out the object to be processed are attached to a portion corresponding to the communication port 9.

The sorting section 5 includes a swing sorting device 5A that transfers and sorts the objects to be processed in the same direction as the direction in which the objects are transferred by the handling chamber 3, and a winnow for generating a sorting airflow 5B.
It is equipped with

The second reducing device 8 includes a rotating blade 8A that flips up the second item, and a cylinder 8B that guides the second item that is flipped up.
The thrower is equipped with a thrower, and the scattering supply of secondary materials into the processing chamber 4 is carried out in such a manner that heavier secondary materials such as grains and twig stalks are blown farther without stalling. In other words, the second material is subjected to specific gravity selection by its scattering supply.

A shielding plate 10 is provided within the processing chamber 4 and at a location corresponding to the communication port 9 to cover the upper side of the processing cylinder 4A. This shielding plate 10 is provided with an upper surface 10a that is substantially curved so as to guide a second object placed thereon downward to both sides in the axial direction of the processing cylinder.

According to the configuration of the above embodiment, the shielding plate 10 allows
Processing cylinder 4A corresponding to the communication port 9 of the second scattering supply material
Since the direct supply to the section can be prevented, it is possible to prevent the second material from being directly supplied to the processing cylinder 4A section and being supplied into the processing chamber 3 without being processed. The plate 10 allows the object to be processed (second object) to be removed by centrifugal force at the portion corresponding to the communication port 9.
Since the material to be processed can be guided toward the communication port 9 side while preventing it from jumping out, the workpieces transferred to the communication port 9 position by the rotation of the processing cylinder 4A can be transferred to the processing chamber through the communication port 9. 3 can be supplied smoothly and reliably.
