Description

[Detailed description of the invention] This invention prevents the risk of the pre-reaping treatment section going up and down by locking the operating tool in the neutral position during work or inspection. Regarding the operating structure of a combine harvester, in which a pin for locking the operating tool for raising and lowering the pre-harvesting section in the neutral position is provided with a pin that can be freely released, the operating tool lock structure can be easily and quickly assembled and replaced. With the goal.

Next, embodiments of the present invention will be described based on the drawings.

A boarding operation unit 3 and a threshing unit 4 are mounted on a crawler type traveling machine base 1, and as the machine advances, planted grain culms are raised and harvested, and the harvested grain culms are supplied to the starting end of the threshing unit 4 before reaping. The processing section 5 is connected to the front part of the traveling machine stand 1 to constitute a combine harvester.

By vertically swinging the pre-processing frame 6 of the reaping pre-processing section 5 attached to the traveling machine stand 1 by the hydraulic cylinder 7, it is possible to move the reaping pre-processing section 5 up and down on the machine stand 1. The operating tool 8 for the control valve 7 is connected to the operating section 3.
It is attached to a control tower 9 so as to be able to swing freely around a support shaft 10, and the pre-reaping treatment section 5 can be raised and lowered from the ground using the operating tool 8 in order to adjust the cutting height, drive on the road, etc.

A slidable pin 11 is inserted into the operating tool 8 to lock it in the neutral position, an operating tool 12 is vertically swingable to switch the pin 11 between the locked state and the unlocked state, and the pin 11 is slid into the operating position. Coil spring 13 for dynamic biasing and operating tool 1
The pin 11 can be slid by the swinging operation of the spring 1, and the pin operation tool 12 can be moved by the spring 1.
A cam member 14 is attached to the control tower 9 to hold the operating tool 8 in the unlocked position against the pressure of The pre-reaping treatment section 5 is configured to prevent the danger of the pre-reaping treatment section 5 being raised or lowered due to manual operation, and is also configured to switch the operating tool 8 between a locked state and an unlocked state by swinging the operating tool 12. .

A mounting member 1 that removably screws all of the pin 11, pin operating tool 12, coil spring 13, and cam member 14 to the control tower 9;
By simply attaching and detaching the mounting member 15 to the control tower 9, all the constituent members for safety measures can be attached to and detached from the aircraft body in one piece.

Note that the coil spring 13 can be changed to a disc spring, a plate spring, rubber, or the like, and these are collectively referred to as the elastic member 13.

Further, the present invention is configured such that the pin 11 is configured to act on an interlocking mechanism between the operating tool 8 and the control valve, and the reaping pre-processing section 5 is configured to be configured to act on an interlocking mechanism between the operating tool 8 and the control valve. It can also be applied to devices configured to be raised and lowered by manual operation.

In summary, the present invention provides the aforementioned pin 11 and the pin 1 in the operation structure of the combine harvester described above.
1, an elastic member 13 that urges the pin 11 to the operating position, and a member 14 that holds the pin operating tool 12 in the unlocked position. It is characterized in that it is attached to a single attachment member 15 that can be freely attached and detached.

That is, by simply attaching and detaching the mounting member 15, the pin 11, the operating tool 12 and the elastic member 13 thereto, and the operating position holding member 14 with respect to the pin operating tool 12 can be integrally attached and detached. The tool lock structure can now be easily and quickly assembled and replaced, resulting in a structure that is extremely convenient in terms of manufacturing and repair.

Note that although reference numerals are written in the claims section of the utility model registration for convenience of comparison with the drawings, the present invention is not limited to the structure of the attached drawings by such entry.
