The straw discharge treatment unit 15 is openable by rocking motion with the shafts 19, 19 as the rotating center.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a support structure for a straw disposal device such as a cutter attached to a straw disposal section at the rear of a threshing machine.

Prior Art Conventionally, in order to reinforce the rear side plate of the handling chamber of a threshing machine, the rear side plate, the straw processing device attached to the rear of the threshing machine, and the machine base on which the threshing machine is mounted were integrated by a series of reinforcing support members. It was designed to be connected and maintained.

Problems to be Solved by the Invention According to the conventional type, although the rear side plate of the handling chamber and the waste straw processing device are firmly held, the waste straw processing device in particular is integrated into the thresher side. However, it was not possible to swing it open and close, and maintenance could not be facilitated.

In order to solve this problem, the present invention is designed to enable the straw disposal device to swing open and close while effectively utilizing a reinforcing support member.

Means for solving the problem, that is, one technical means according to the present invention is that the rear side plate 10 of the handling chamber 8 of the thresher 2 and the rear side of the straw processing device 15 located in the straw removal section 3 of the threshing machine, The machine base 6 on which the threshing machine is mounted is connected and held by a series of reinforcing support members 18, and
The middle part of this reinforcing support member 18 and the connecting part to the machine base 6 are configured to be rotatable around vertical support shafts 19, so that the waste straw processing device can swing around the support shafts. It is characterized by being configured so that it can be opened and closed dynamically.

Effects of the Invention Therefore, according to the configuration of the present invention, the rear side plate of the handling chamber, the waste straw processing device, and the machine stand are connected and held by a series of reinforcing support members, so that the rear side plate of the handling chamber is It is difficult to deform into
The rigidity of the handling room can be ensured, and the rear part of the exhaust/S processing equipment is supported from the machine stand side, so it is held firmly5, while the reinforcing support member can be rotated freely by the vertical support shaft. Because of this structure, the straw disposal device supported by this can swing open and close around its support shaft,
We were able to facilitate maintenance.

Example An embodiment of the present invention will be described below based on the drawings.

The threshing machine 1 mainly includes a threshing section 2, a sorting section 3, and a straw discharging section 4, and is mounted on a machine stand 6 equipped with moving rollers 5.

In the threshing section 2, a handling chamber 8 in which a handling cylinder 7 is mounted on an internal axis is connected to front and rear side plates 9.
・Comprised of 10 and left and right side plates 11 and 12, the handling room-
There are 13 foot chains installed on the side.

The sorting section 3 extends from below to the rear of the threshing section 2, and above the rear part of the sorting section and behind the threshing section 2, a straw removal section 4 equipped with a bamboo straw conveying device is constructed.

The waste straw processing device 15 consists of a disc-shaped disc cutter 16, and at least left and right side plates 17, 1 having a framework structure.
7, and is mounted on the rear frame part of the sorting part 3, located on the straw removal part 4 side.

The reinforcing support member 18 has a front end fixed to the rear side plate 10 of the handling chamber 8 on one side of the straw removal section 4 of the threshing section, and extends rearward from this in a substantially horizontal posture to form a rear end portion. a horizontal portion 18a located above the rear of the straw disposal device 15; and a vertical portion 18b that descends substantially vertically from the rear end of the horizontal portion 18a and is fixed to the rear of the side plate 17 of the straw disposal device. and a folded part 18c which is folded back obliquely forward and downward from the lower end of the vertical part 18b and whose lower end is connected to the machine base 6. and.

The middle part of the horizontal part 18a of this reinforcing support member 18 and the connecting part of the lower end of the folded part 18c to the machine stand 6 are configured to be rotatable around the support shafts 19 on the same longitudinal axis P. Accordingly, the straw disposal device is rotated by its support shaft 19
・It is constructed so that it can be opened and closed by swinging around 19 as the center of rotation.

Further, one side end of the straw disposal device 15 is connected to the side frame plate 3a of the sorting section 3 around another support shaft 20, 20 on the same axis P as the vertical support shafts 19, 19. It is supported on bearings for rotation. Therefore, if the other end of the straw disposal device is pulled rearward by releasing the locking mechanism that can be freely engaged with the rear frame of the sorting unit, the straw disposal device will be moved to the vertical support shaft 19 on the one end side. It can be easily swung open with 20 as the center of rotation.
