Description

[Detailed Description of the Invention] [Industrial field of application] The present invention provides a weeding tool at the front end at one of the left and right ends of the pre-mowing processing unit so that it can be adjusted forward and backward and detachably from the weeding tool mounting frame. At the same time, the weeding rod that suppresses the fall of the grain culm into the straw is moved laterally with respect to the fuselage in a state in which the weeding tool is along the fuselage front-rear direction in the outer fuselage of the warp and is lateral to the fuselage. The present invention relates to a weeding structure of a reaper harvesting machine, the front end of which is bent to attach to the weeding tool attachment frame.

[Conventional technology]

Conventionally, as a weeding structure of this type of harvesting and harvesting machine, for example, one having a structure disclosed in Japanese Utility Model Publication No. 1-79932 has been known.

[Problems to be solved by the device]

In the above structure, since the front end of the weeding rod is attached to the weeding tool mounting frame in which the weeding tool can be adjusted back and forth and is detachable, when the weeding tool is in the retracted position, the weeding tool is There is little gap between the rear end of the tool and the front part of the weeding rod for the uncut side grain culm, but when the weeding tool is adjusted to the front position, the rear end of the weeding tool and the weeding rod are There is a wide gap between the front part of the pad and the uncut side, and the uncut grain culm that has fallen into the gap is pushed down by the front end of the weeding rod.
There is a drawback that there is a high possibility that the vehicle will be stepped on by the traveling device. In addition, in order to eliminate this problem, there is also a means to extend and retract the weeding rod and attach its front end to the weeding tool, but in this case, when removing the weeding tool from the weeding tool mounting frame,
It is necessary to separate the front end of the weeding rod from the weeding tool, and a means to fix the weeding rod, which has lost its support at the front end, to the machine body by banding etc. is also necessary. It has been required to perform a troublesome operation when the weeding tool is attached and detached, such as when it is mounted on a carrier vehicle and moved, or when it is stored in a barn.

The present invention has been made in view of the above circumstances,
Regardless of adjusting the front and back position of the weeding tool, it is possible to prevent the uncut grain culm from entering between the rear end of the weeding tool and the front part of the weeding rod without any trouble, and to attach or detach the weeding tool. It is an object of the present invention to provide a weeding structure for a harvesting harvester that can eliminate the troublesome operation of time.

[Means for solving the problem]

In order to achieve the above object, the weeding structure of the mowing harvester according to the present invention is such that the weeding tools at the front end at the left and right ends of the pre-cutting processing unit are adjusted back and forth with respect to the weeding tool mounting frame and attached and detached. A weeding rod that is freely installed and that prevents the grain culm from falling into the waft, and the weeding tool is in a state in which the weeding tool is lateral to the wing in the outer lateral waft of the wadding. In the weeding structure of the reaper harvester that is attached to the weeding tool mounting frame with its front end curved so as to be movable in the distance, while extending the elastic rod toward the rear from the weeding tool, The rear free end of this elastic rod is inserted into and supported by a through hole formed in the forward direction in the curved portion of the front end of the weed rod so as to be retractable, and is configured to be movable back and forth in the rod length direction. Characteristic configuration.

The operation and effect of this characteristic configuration are as follows.

[Action]

That is, the elastic rod extending rearward from the weeding tool is movable in the elastic action of the elastic rod itself and in the rod length direction in which the elastic rod extends along the front and rear with respect to the weeding rod. , The front end of the weeding rod is inserted into and supported by the forward hole of the curved portion so that the weeding implement and the weeding rod can be installed over the wales. Regardless of the forward / backward adjustment of the sward or the movement of the swarding rod relative to the airframe, the elastic rod can always be maintained in the front and rear erection state. Even if a wide gap is formed between the front end of the rod and the saw, the body of the uncut grain can be prevented from falling into the saw.

In addition, when the reaper is mounted on a transport vehicle or when the weeding tool is removed from the weed mounting frame when it is stored in the barn, the elastic rod is pulled out from the through hole of the weeding rod together with this weeding tool, and then When the weeding tool is attached, the elastic rod is inserted again into the through hole of the weeding rod to obtain the original working state.

[Effect of device]

Therefore, according to the present invention, it is not necessary to attach or detach the member for preventing the uncut side grain stalk from falling into the straw over the rear end of the weeding jig and the front end of the weeding rod, and it is simply the weeding tool. With the simple operation of just adjusting the front and back, we were able to always weed well. Also, the operation for attaching and detaching the weeding tool can be easily performed.
