DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mounting structure of a plate-like hitch which is provided with a raising and lowering device adjacent to a raising case of a mowing portion and connects a weeding board to a mowing frame.

[0002]

2. Description of the Related Art In order to shorten the overall length of a machine and facilitate transport and storage, a weeding board is detached and attached inside a raising case, and a protruding weeding board is formed with a pipe material and fitted to a cutting frame. Although it was inserted, loosening occurs and the bolting operation becomes difficult because it is surrounded by the transport member, so extend the tip of the weeding pipe to the front of the raising case and press-fit the mounting hole for attaching the weeding plate directly The part which was provided in the part
No. 6,086,045.

[0003]

Since the weeding plate of the device for raising and lowering protrudes further forward than the normal position, it easily collides with an obstacle and the cutting frame is deformed, so that it takes time to repair the cutting frame. Also, in a multi-row mowing frame, the inclination of the weeding board differs depending on the installation location and the number of types increases, and in wetlands where crawlers sink, the tip of the weeding board faces upward,
There is a problem that the falling rod is no longer lifted and remains mowing.

[0004] By changing the bent shape of the plate-like hitch connecting the lodging device and the weeding plate, the interchangeability of related parts is improved, and the plate-like hitch that protects the cutting frame by being deformed by a compressive load due to a collision. In addition, the present invention provides a weeding board mounting structure that can be adjusted up and down with its upper part serving as a rotation fulcrum.

[0005]

Means for Solving the Problems In a lodging raising device which is juxtaposed to a raising case for multiple cutting with different mounting angles of a weeding plate, a plate hitch for connecting a weeding pipe of a cutting frame and a weeding plate is folded. This is a weeding board mounting structure in which the curved shape is changed so as to be adapted to a plurality of weeding board angles.

[0006] A weeding plate is connected to a tip of the cutting weeding pipe and a projecting weeding plate by a plate-like hitch, and a locking tool provided at the lower end of the tilting device is fitted to the plate-like hitch. Means were taken to support the device from the frame.

A bending portion is formed in the middle of the cross section of the plate hitch which is screwed into the fastening hole of the weeding pipe, so that the cutting frame is deformed by a compressive load caused by a collision to protect and repair the cutting frame. We have taken measures to make the attachment / detachment structure that can be fastened at the forefront of the fuselage.

A pivot point is formed by inserting a fulcrum bolt into a mounting seat on which the latching member of the falling and raising device and the plate-like hitch are superimposed, and the hitch hole is elongated to adjust the weeding board up and down. We made measures to make it possible and to adjust the weeding posture where the tip touches the ground in wetland work.
