Description

Detailed Description of the Invention [Industrial Field of Application] The present invention relates to a processing chamber in which a handling cylinder that is driven for lower handling is pivotally supported, and a processing chamber in which a processing cylinder that is driven in the opposite direction to the handling cylinder is pivotally supported. The threshing device is configured such that two chambers are arranged in parallel with a feed chain, an opening is formed that communicates the two chambers over substantially the entire length thereof, and the threshed material in the handling chamber is sent into the processing chamber through the opening. Therefore, even if the amount of shell culm supplied into the handling chamber increases, the increased amount of shell culm is introduced into the processing chamber through the opening that communicates the two chambers, and the amount of shell culm that is supplied to the processing chamber increases. By suppressing the situation where a part of the grain is pressed against the gap between the handling drum and the receiving net located below the handling drum, the temporary effect of tooth extraction is not sufficiently applied, and unhandled items are likely to occur. This invention relates to a threshing device with improved processing capacity.

[Prior art]

In a conventional threshing device of this kind, a receiving net stretched over the lower part of the handling chamber was formed in the shape of a circular arc concentric with the handling barrel.

[Problem that the invention seeks to solve]

Because of this concentric circular arc shape, the trajectory of the processed material sent from the bottom of the processing chamber to the top of the processing chamber is directed toward the vicinity of the ceiling wall at the processing chamber entrance, and the rotation trajectory of the processing cylinder There were times when the transfer could not be carried out smoothly due to lack of synchronicity.

An object of the present invention is to perform simple modification to a reception network.
Therefore, the action of sending the processed material from the handling chamber to the processing chamber is as follows:
The purpose is to provide something that can be operated more smoothly and that does not reduce the operating speed in the handling room.

[Means for solving problems]

The characteristic configuration according to the present invention is such that the terminal end portion facing the opening of the receiving net stretched along the handling drum rotation trajectory in the lower part of the handling chamber is gradually separated from the handling drum rotation trajectory, and 1. Protrusions for guiding the shell culm are set upright along the rotational direction of the handling cylinder at appropriate spacing in the axial direction of the handling cylinder, and the upper edge of these ridges is placed at a point along the rotational trajectory of the handling cylinder. , its effects are as follows. .

[For production]

By gradually separating the end portion of the pick and receiving net from the rotation trajectory of the processing cylinder, the trajectory of the material being sent from the handling chamber to the processing chamber can be set in a state in which it lies in the tangential direction of the rotation trajectory of the processing cylinder. Surplus material to be processed in the handling chamber can be smoothly fed into the processing chamber, and this gradual separation structure allows the shell to be gradually separated from the portion formed between the handling cylinder and the receiving net below the handling cylinder. It is possible to substantially suppress the decline in the circumferential direction of the machine caused by a portion of the culm being pressed by the ridge for guiding the shell culm, which is provided upright along the rotation locus of the handling cylinder.

[Effects of the invention] By simply modifying and adding a simple structure to the receiving net, which is originally a component, it is possible to smoothly feed the material into the processing room while suppressing the decline in the circumference of the tentative fabric in the handling room. We have now been able to provide this type of threshing device that is useful for expanding its capacity.

〔Example〕

As shown in Figures 8 and 4, the feed chain (1
) in parallel with a treatment chamber (2) and a treatment chamber (3) having an inlet (3a) for the second reduction material, and a lower-level drive built in them;
and a handling cylinder (with handling teeth (4a)) which are driven in mutually opposite directions;
4) and handling teeth (5 & processing cylinder (5)) are arranged in parallel in the horizontal direction so that their axes are parallel to each other, and a swing sorting device is installed below both chambers (2) and (3). (6) is disposed in the sorting room (7), and includes a winnow (9) that generates sorting air in the sorting room (7), a dust exhaust fan (3), and a discharge screw (10B). sorting first item collection department αQ
The threshing device is equipped with a second sorting material collecting section (6) equipped with a carry-out screw (ll&), and a thrower (2) for sending the second material to be collected to the entrance (8a) of the processing chamber (3). It is composed.

An opening α4 is formed that communicates the handling chamber (2) and the processing chamber (3) over substantially their entire length, and the material to be processed in the handling chamber (2) is transferred into the processing chamber (3) through this opening α◆. Due to the structure, even if the amount of husk supplied to the handling room (2) increases and a large amount of threshed material is generated, it is immediately sent to the processing room (3) and the husk is sent to the handling room (2). Eliminate retention in
“Leftover,” or “sasashi paddy.”

This phenomenon can be reduced. In addition, on the inner wall surface of the processing chamber (3), receiving teeth Q for the handling teeth (5 &) implanted in the processing barrel (5) are placed on both lateral sides of the handling teeth (5a), as viewed from the surface direction. The reeds are arranged in a staggered manner to exert a strong handling action, and the threshed material, which has a short residence time in the handling chamber (2) and has not received sufficient handling action, is removed from the threshing chamber (3). This allows for sufficient single grain processing.

In the lower part of the handling chamber (3) having the above-mentioned configuration, a shell is placed between the handling teeth adjacent to each other in the axial direction of the handling cylinder, with respect to the receiving net QQ stretched along the rotation trajectory of the handling cylinder. A guide plate αη for guiding the culm is erected to increase the circumference of the mechanism, and the terminal portion (15A) facing the opening (141) of the receiving net αG is
It is designed to gradually move away from the rotation trajectory of the processing cylinder (5), and is stretched along the tangential direction of the rotation trajectory of the processing cylinder (5), from the processing chamber (2) to the processing chamber (3). It is possible to send the processed material smoothly. The receiving net terminal portion (15
A) A ridge Q for guiding the culm is located between the guiding teeth (4a) and the guiding plate αη which are adjacent to each other in the direction of the axis of the handling body, and the upper edge of It is erected along the rotational trajectory of the receiving net, and by setting the end portion (15A) of the receiving net apart from the rotating trajectory of the handling cylinder, a portion of the shell culm that is pressed between the receiving net (4) and the receiving net during the processing. It is possible to compensate for the fact that the mechanism is not sufficiently exerted by the protrusions Q...fist.

[Another example]

As shown in FIGS. 5 and 6, the end portion (17A) of the guide plate αη facing the opening Q◆ is extended and enlarged to follow the rotation locus of the handling cylinder, so that the protrusion αQ has a dual-purpose configuration. It may be something planned.

This type of threshing device may be used by being mounted on a threshing device-equipped machine such as a harvester in addition to a combine.
