Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides for driving and rotating the culm, which is horizontally supported and conveyed by a feed chain, around an axis along the culm conveying direction, and in which a large number of husk culms are conveyed in the direction of the culm body. The present invention relates to an improvement of a threshing device configured to perform threshing processing using a group of handling rotors arranged in parallel.

The above-mentioned threshing device stretches the shell culm in a straight line and threshes it with a group of many handling rotating bodies arranged in parallel in the direction of culm growth. It has the feature that it only needs to be sufficiently small, and the vertical width of the threshing section can be made small. However, this kind of threshing equipment that has been proposed so far has a structure in which it is passed between the shell culm metal plate rotating body group and a filtering material such as a receiving net installed below it.
In cases where the culm volume is large, the handling action of the filter medium on the culm may not be sufficiently effective, resulting in only cutting.

In addition, in order for the threshing from the shell culm and the stirring treatment of the processed material separated from the shell culm to be carried out at the same location for filtration prevention,
When the grain culm volume increases or when the husk culm is wet, the husk itself becomes an obstacle to the agitation process of the processed material, and it is not only possible to prevent the grain from becoming single grains, but also to prevent the processing on the filter material. Due to the retention of substances, the filtration performance was also reduced.

This invention was made in order to solve the above-mentioned problems of this type of threshing device that uses a large group of handling rotating bodies. On both upper and lower sides of the culm conveyance path, a large number of handling rotary bodies that are driven and rotated around an axis along the culm conveyance direction are arranged in parallel in the direction of the culm body, and each handling rotary body is placed on the culm conveyance path side. A filter material for grain sorting is installed along the lower part of the lower handling rotating body group, and the unfiltered material is placed on the feed chain side of this filter material. It is at a certain point that it forms an outlet.

According to the above structure, since the husk culm is handled from above and below and processed by a group of rotating bodies, it has become possible to handle all of the husk culm and have all the rotating bodies act on it, making it possible to thresh without leaving anything untreated. Since the filter material is installed below the handling rotary body group, the processed material separated from the grain culm is immediately sent to the bottom of the handling rotary body group by its own weight or the rotational force of the handling rotary body. The filter material is stirred between the rotary body group and the filter material. In other words, the threshing from the shell culm and the stirring of the processed material separated from the shell culm are performed at greatly different vertical positions, and as a result, the grain is not disturbed by the shell culm on the filter medium. The threshed product can be handled and agitated sufficiently by a group of rotating bodies, and the entire grain can be removed into single grains, and the grains can pass through the filter media reliably and smoothly.

Moreover, since the feed chain side of the filtration medium is fully formed with a discharge port for unfiltered matter, the filtration medium is treated with processed materials that are agitated by the lower handling rotating body group rotating toward the feed chain side. The unfiltered matter inside, that is, straw waste, is smoothly sent to the outlet side and quickly discharged.
This results in less straw debris remaining on the filter material, further improving filtration performance.

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

As shown in Figs. 1, 2, and 3, the culms are held in a horizontal position by the feed chain (1) and conveyed through the handling chamber (2). A handling rotary body (3) in which plate-shaped handling teeth (8a) are fixedly fixed to a rotating shaft (3a) having an axis along the conveying direction at regular intervals in the axial direction; At the same time, the rotation trajectories of the handling rotors (3) are made to overlap with each other horizontally and vertically, and a flat receiving net (4), which is a filter material, is installed at the bottom of the handling chamber (2).
) is installed close to the group of lower rotating bodies (3), and (4a) is formed, thereby forming a threshing section.

At the bottom of the threshing section, the grains and small straw waste that have passed through the receiving net (4) are received by a swinging sorting plate (5), and the grains are Furthermore, the sorted grains are transported out of the device by the conveying screw (7) at the bottom, and the cross-flow fan (9) is installed to suction and discharge floating dust etc. from the dust exhaust port (8). The threshing device is constructed as follows.

Next, the processing in the threshing section will be explained in detail.

The husks that are held and conveyed in a horizontally suspended position by the feed chain +11 are carried into the handling room (2), and are uniformly threshed from above and below in the threshing space (A) of the group of handling rotors (3) in two stages, upper and lower. Of the processed materials separated from the culms, the grains and relatively small straw waste pass between the lower handling rotating bodies (3) and fall onto the receiving net (4). 4).
In addition, relatively long fluff waste is sent to the tip side by the upper and lower handling rotating bodies (3) group, and then transferred to the lower right end handling rotating body (3).
3) and is sent onto the receiving network (4).

On the receiving net (4), the threshed material is handled on the lower side by the rotating body (3)
The grains that have been agitated by the group and have already been made into single grains pass through the receiving net (4), and the grains that have been ground have been made into single grains by this stirring and then pass through the receiving net (4).

Since each handling rotary body (3) rotates toward the feed chain ill side with respect to the receiving net (4), the metal bodies to be processed are sent to the feed chain +1) side, and fine processing including grains is carried out. The material passes through the receiving net (4), and the unfiltered material consisting of large straw waste reaches the outlet (4a) and is discharged.

In other words, the lower handling rotary body (3) threshes the entire shell culm in the threshing space (A), and at the same time stirs, transports and discharges the threshed material on the upper surface of the receiving net (4).

In addition to using the receiving net (4) as the filter material, it is also good to use a cone cape in which rods are arranged side by side with a small spacing.
Alternatively, a filter material may be used in which fixed treated teeth are arranged upwardly at equal intervals.

Further, the formation range of the discharge port (4a) provided at the end of the filter medium may be provided in the front and rear rotation length of the handling chamber (2).
