Description

DETAILED DESCRIPTION OF THE INVENTION "Industrial field of application" The present invention relates to a combine harvesting device in which a harvesting frame for attaching a grain culm raising member and a harvesting member is provided so as to be movable left and right.

"Prior Art" Conventionally, as disclosed in Japanese Patent Laid-Open No. 64-34212, there has been a technology of rotating a screw shaft and moving the screw shaft in the axial direction to laterally move the cutting frame.

[Problems to be solved by the invention] However, in the above-mentioned prior art, since the screw surface of the screw shaft is exposed to the outside, rotation of the screw shaft is hindered or impossible due to adhesion of soil, etc. However, there are inconveniences such as that the right and left movements cannot be properly performed, and the durability of the driving member that rotates the screw shaft is significantly reduced. Further, as disclosed in Japanese Utility Model Laid-Open No. 63-112440, there is a technique of providing a cylinder type cover and inserting a screw shaft therein, but there is a problem that the structure becomes complicated.

"Means for Solving the Problem" Therefore, the present invention is a combine harvester for moving a harvesting frame for mounting a grain culm raising member and a harvesting member left and right with respect to a machine body by screwing a male screw member and a female screw member. , The male screw member is made shorter than the female screw member so that the male screw member is movable only within the range of the female screw member, and the male screw member is provided on the cutting frame side, and the cutting frame is provided on the main beam side for supporting the combine machine. It is characterized in that a female screw member is provided.

[Operation] Therefore, by threading the male screw member into the female screw member, the reaping slide operation can be performed without projecting the male screw member to the outside of the female screw member, and the female screw member can also be used as a protection member for the male screw member. The outer structure of the member can be simplified and foreign substances can be easily prevented from entering each screw member, and by attaching a long female screw member to the combine machine side, the runout on the short male screw member side can be reduced. The harvesting frame supporting posture can be stabilized more easily than before.
