Abstract

PURPOSE:To continuously and smoothly perform threshing and grading operation by cutting off power transmission to a reaper and thresher and transmit power only to a grader when the reaper is lifted to a nonoperating position in turning the reaping end, etc. CONSTITUTION:When a reaper 2 is lifted to a nonoperating position relatively to a car body 1, power transmission to the reaper 2 and a thresher 3 is cut off to transmit power only to a grader 4. The reaper 2 is constituted so as to lower to an operating position, transmit the power thereto and interlock with the thresher 3. Thereby, interlocking is performed to constitute a combine. As a result, threshing and grading operation can be continuously and smoothly carried out.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention relates to a combine harvester, and can be used when turning the cutting end at a corner.

Conventional technology Conventionally, when turning around the corner of the cutting edge, etc.
There is a technique in which the power transmission to the reaping device is cut off when the reaping device is raised to a non-working position when the reaping husk is exhausted, and the transmission is turned on when the reaping device is lowered to the working position.

Problems to be Solved by the Invention When the reaping culm disappears and the reaping device is raised to a non-working position relative to the vehicle body, such as when turning around a corner of the reaping end, and the power transmission to the reaping device is cut off, The reaped husk culm is held between the foot chains of the threshing device and transferred, but since the reaped husk culm is interrupted, if the car body is turned or moved backwards during this turn, the husks being transferred will be The transportation posture of the culm may be disturbed, or the culm may fall. Furthermore, if the power transmission to the first sorting device is cut off, there are problems such as the threshed grains undergoing sorting clogging the sorting device or causing poor sorting during subsequent sorting.

Therefore, in this invention, when the reaping device is raised to a non-working position when turning the cutting end, the power is cut off to the reaping device and the threshing device, and only the sorting device is transmitted. The purpose is to perform threshing and sorting work smoothly.

Means for Solving the Problems This invention provides that when a reaping device (2) is raised to a non-working position with respect to a vehicle body (1), the reaping device (2) and the threshing device (
The combine harvester is constructed in such a manner that only the sorting device (4) is transmitted while the transmission to (3) and (3) is cut off, and these are transmitted in an interlocked manner as they are lowered to the working position.

Effect of the invention When the reaping husk disappears at the corner of the reaping end and the reaping device (2) is raised to the non-working position relative to the vehicle body (1), the reaping device (2) and the threshing device (3) The transmission to is cut off and stops, but only the sorting device (4) is transmitted. When the vehicle body (1) is turned and the reaping device (2) is moved along the planting row and lowered to the working position, the power is transmitted to the reaping device (2) and the threshing device (3) to perform reaping and threshing. It will be done.

Effects of the invention When the car body (11) turns, the power is cut off to the reaping device (2) and the threshing device (3), and only the sorting device N (4) is transmitted, so the sorting device (4) is continuously operated. The sorting is carried out without causing poor sorting or clogging, and the power transmission to the threshing device (3) is cut off, so that the cut husk culms are held in the foot chain and transported in a continuous manner. Since it is stopped in the same state, the Wi feeding posture is not disturbed, the puller does not fall from this foot chain, and,
When the reaping device (2) is lowered, the power transmission between the reaping device (2) and the threshing device (3) is interrupted, so that even when the reaped husk culm is cut off and turned, the reaped husk can be continuously and smoothly removed. can be transported and sorted.

The control platform is equipped with a lift lever (m) that can freely rotate in the front and rear directions, and the solenoid valve is electrically switched by the back and forth rotation of the lift cylinder (6), which extends and contracts by supplying and discharging pressure oil to the lift cylinder (6). The structure is such that the reaping device (2) is moved up and down.

A belt is passed between the output pulley Ob of the transmission case (7) and the reaping input boot provided on the input shaft at the base of the reaping frame (13), and this belt is relaxed. Tension pulley (to) reaped frame 03
It is provided on an arm 211 that is fixed to.

The structure is such that the transmission from the to the reaping input pulley (19) is turned off, and when it descends to the working position, the belt is tightened and the transmission is turned on.

The threshing device (3) is equipped with a handling trunk e1) and a foot chain Q3 along the handling opening of the threshing room that houses the handling trunk e1).
A culm transfer chain j is provided to receive the threshed culm transferred by the foot chain tZa and transfer it to the outside of the machine.

The sorting device (4) is provided with a swinging sorting shelf (24) that receives the threshed grains by the handling cylinder Q1), transports them in a swinging motion, and then sorts the grains from straw waste. From the front to the rear, a Karakou fan (C), the first spiral (To), and the second ds spiral are sequentially arranged. Also, this oscillating sorting WQ4
