Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a combine grain tank device equipped with a grain tank together with a mowing section and a threshing section.

"Prior Art" Conventionally, as shown in Japanese Utility Model Laid-Open No. 59-34542, an increase tank is provided on the machine outer side of the grain tank, and the increase tank is attached to the grain tank so that it can be freely moved in and out around a fulcrum at the lower end. There was technology.

"Problem to be solved by the invention" In the conventional technology, the rod connecting one end side to the increasing tank is slidably connected to the grain tank via the spring, so that the rod connecting each tank is The rod cannot be installed inside the tank, and the rod easily protrudes to the outside of the tank, especially when the tank is retracted, and the upper side of the tank cannot be easily supported, and the rod mounting structure can be easily made compact. There is a problem in that it cannot be easily attached to the upper part of the inside of the tank where there is little contact with the grain.

[Means for Solving the Problems] Therefore, the present invention provides a grain combiner in which the grain increasing tank is provided on the machine outer surface of the grain tank, and the grain increasing tank is attached to the grain tank so that the grain expanding tank can be freely inserted into and removed from the grain tank. In the tank device, a link base end portion is rotatably connected to the inside of the grain tank via a rotation shaft, a rod is bendably connected to the link tip end portion, and the rod and the inside of the upper portion of the weight tank are spring-loaded. It is characterized in that the increasing tank is advanced or withdrawn by switching the link between two positions.

[Operation] Therefore, the upper inside of each tank can be easily connected by the bendable link and the rod, and the link and the rod can be compactly mounted inside the upper side of each tank.
Even if the link is fixed at the advance or retract position, the spring absorbs the deformation tank deformation force due to the weight of the grain or the impact from the outside, and the two-position switching stroke of the link and the movement amount of the expansion tank in and out. Even if there is a difference, it is absorbed by the spring, and it is possible to apply a substantially constant spring force to the weight increasing tank at any of the position of moving in and out even if the position of grain moves or impact vibrations. Can be stably supported, vibration or damage of the increasing tank can be easily prevented, and simplification of the increasing tank loading / unloading mechanism formed by the link can be achieved.
