Description

[Detailed description of the invention] In order to facilitate the inspection of the interior of the machine, the present invention has developed a tank for storing threshed grains and a screw conveyor for lifting and removing the grains from the tank. The present invention relates to a transmission structure for a mobile threshing machine in which a lateral screw conveyor is installed in the tank so as to be rotatable around a rotation axis and supplies grains to the lifting screw conveyor.

Conventionally, in configuring the transmission structure of the above-mentioned mobile threshing machine, one end of the rotating shaft 10a of the horizontal feeding screw conveyor 10 provided at the inner bottom of the tank 5 was connected to the tank, as shown in FIGS. 4 and 5, for example. 5. A belt transmission mechanism 2 with a tension pulley type clutch device 21' is connected to a power take-off shaft 19' which protrudes from the outer wall and whose protruding end is linked to the prime mover 25.
The lower end of the rotating shaft 12a of the lifting screw conveyor 12, which is interlocked and connected by 0 and arranged coaxially with the rotating axis P of the tank 5, and the rotating shaft 10a of the lateral screw conveyor 10. The other end is interlocked and connected by a bevel gear mechanism 22' etc.
By operating the tension pulley type clutch device 21', both screw conveyors 10,
12 is rotated to take out the grains in the tank 5. However, for example, when inspecting the threshing section 3 disposed on the side of the tank 5 from the tank 5 side, the tank 5 must be rotated. Each rotation operation involves removing the belt of the belt transmission mechanism 20 that interlocks the traverse screw conveyor 10 and the power take-off shaft 19', and also requires wrapping the belt at the end of inspection. There were problems such as the work of disconnecting these transmission structures was troublesome, and the efficiency of inspection work was also lowered because of this.

In view of the above-mentioned conventional situation, an object of the present invention is to make it possible to easily rotate a tank without having to disconnect the transmission structure such as attaching or detaching a belt.

In order to achieve the above objects, the present invention interlocks and connects the lateral feeding screw conveyor and the lifting screw conveyor, and also connects the power transmission shaft on the prime mover side to the lifting screw conveyor. They are interlocked and connected, and this characteristic configuration provides the following effects.

In other words, the power from the prime mover is input to the rotating shaft of the screw conveyor for lifting, which is arranged concentrically with the rotating axis of the tank, and the power of the screw conveyor for lateral feeding is input from that rotating shaft. Therefore, the power transmission structure for both screw conveyors can be maintained in an interlocked state regardless of the rotation of the tank, and the power transmission structure for both conveyors can be maintained by connecting and disconnecting the power transmission belt each time the tank is rotated. By omitting the work of uncoupling the structure, the rotating operation of the tank can be facilitated, and in turn, it has become possible to improve the efficiency of work such as inspection of the aircraft body that involves rotating the tank.

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