Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides a grain culm transfer path (
The present invention relates to a threshing device that threshes grain while transporting the grain along a handling opening.

[Prior art]

Conventionally, in this persimmon threshing device, the grain culm receiver (the net holding plate connected to the receiving net in the handling room) installed along the lower edge of the grain culm transfer path was fixed and clearly visible from the handling teeth. ``The time was constant.

[Ali@ the invention seeks to solve] According to such a conventional structure, when the grain culm supplied into the handling chamber is a short culm, the tip of the grain culm may not be able to sufficiently contact the peripheral surface of the handling barrel. , there was a problem that caused backlogs.

The present invention aims to prevent unhandling of short culms,
The following technical measures were taken.

[Means to solve the problem]

That is, the technical means of the present invention is to provide a grain culm holder 1 which is movable in the far and near directions with respect to the handler 15i8 along the lower edge of the grain culm transfer path 9 in the handling room 7; Culm holder 11t
It is characterized in that it can be operated remotely using a control lever 13 provided near the il-drive section.

[Action/effect of the invention]

Therefore, according to the present invention, when the grain culm is a short culm (shallow handling), the tip of the grain culm can be handled by changing the position of the grain culm receiver in a direction approaching the peripheral surface of the handling barrel. It can be brought into sufficient contact with the grain barrel to prevent unhandled grains, and it also has the advantage of being able to change the position of the grain culm receiver remotely from the operating section, so that immediate action can be taken.

〔Example〕

An embodiment of the present invention will be described below based on the drawings. 1st
The figure shows the overall side view of a combine, in which a threshing device 2 is mounted on a machine body equipped with running rollers 1, a reaping section 3 is mounted on the front part of the machine, and a driving section 4 is installed on the side of the reaping section. It is set up.

The threshing device 2 mainly includes a handling chamber 7 in which a receiving net 5 is stretched over the seeds, the upper part of which is surrounded by a handling barrel cover 6 that can be opened and closed, and a handling tooth that is rotatably installed in the handling chamber 7. 8a, a foot chain 10a and a clamping rail 1 provided along the grain culm transfer route (handling port) 9 on the side of the handling room 7.
It consists of a grain culm holding and transferring device consisting of 0b@lO.

In the handling chamber 7, a grain culm receiver 11 connected to the receiving net 5 is attached to a support shaft 12 at a lower edge position in the vicinity of the handling opening 9.
An operating wire is provided around the periphery so as to be able to swing in the direction of distance from and near the handling barrel 8, and an operating wire is provided so that the grain culm receiver 11 can be remotely controlled by an operating lever 13 provided near the operating section 4. 14 and a swing arm 15, etc., in an interlocking configuration.

For grain culms of normal length, if you reduce the gap between the handle and the grain culm holder, a large amount of straw waste will be generated, which increases horsepower consumption and loss. Return to the proper gap position, but when the culm is short, by moving it closer to the handling tooth side and narrowing the gap, you can prevent unhandled culms from being left untreated.

Note that the operation means for the grain culm receiver may be configured to be automatically operated in accordance with a handling depth control device.

For example, as shown in FIGS. 3 and 4, in conjunction with the switch SW1 on the "shallow" side of the handling depth adjustment sensors 17 and 18 provided in the conveyance path section of the grain culm conveyance device 16 of the reaping section 3, When the adjustment range is exceeded to the shallow side, the grain culm receiver 11 is moved to the handling tooth side by the motor M after a certain period of time.
