The stock aligning device is movable in the lateral direction, and the discharge straw bundling device is configured such that the knot portion is provided above the binding space and the packer and the needle are provided below the binding space. Regarding the straw processing unit.

[Conventional technology]

Such a discharge straw processing unit horizontally moves the stock aligning device according to the root end position of the waste straw conveyed in the posture of falling from the threshing device, and the stock straw ends of the waste straw can be aligned at an appropriate position. Is disclosed in JP-A-60-19416.

Then, in the exhaust straw processing unit that laterally moves the stock aligning device with respect to the machine body, a motor that is an independent power source is provided in the stock aligning device, and the stock aligning device is operated using the power of this motor. It was common.

[Problems to be Solved by the Invention]

However, since the electric power consumption of the motor is relatively large, the capacity of the battery provided in the aircraft must be increased in order to operate stably. Moreover, since the motor itself is expensive, it is generally expensive.

The present invention was conceived in view of such an actual situation, and an object thereof is to make it possible to efficiently and stably transmit the power on the side of the machine body to reduce the cost.

[Means for Solving the Problems]

A characteristic configuration of the present invention is that, behind the threshing device, a discharge straw bundling device for treating the discharge straw in a horizontal position and a stock aligning device are respectively provided, and the stock aligning device is movable in the lateral direction, and The straw bundling device is a discharge straw processing unit configured such that the knot portion is provided above the binding space, and the packer and the needle are provided below the binding space, and the straw binding device is provided in the discharge straw binding device. An output bevel gear is shiftably and integrally rotatably fitted to a horizontal binding drive shaft, and an input bevel gear is provided at a lower end of a vertically oriented stock alignment drive shaft provided in the stock alignment device for the output. A bevel gear and the input bevel gear are engaged with each other, and the stock alignment drive shaft has a two-part structure of an upper stock alignment drive shaft and a lower stock alignment drive shaft, and these two drive shafts are interlockingly connected through a universal joint. In addition, the lower case that supports the input bevel gear and the lower stock alignment drive shaft is restricted in relative movement in the axial direction of the binding drive shaft with respect to the frame of the stock alignment device, and is the shaft of the binding drive shaft. The upper case, which is attached to the frame in a state where movement in a direction orthogonal to the core is allowed, and which supports the upper stock alignment drive shaft, is fixed to the frame of the stock alignment device. Is a characteristic configuration.

The action and effect are as follows.

[Work]

According to the above configuration, when the binding drive shaft first rotates, the output bevel gear fitted to the binding drive shaft integrally rotates, and the input bevel gear that meshes with the output bevel gear rotates in conjunction with the output bevel gear. Then, the lower stock alignment drive shaft provided with the input bevel gear, the universal joint, and the upper stock alignment drive shaft rotate integrally to operate the stock alignment device.

Next, when the stock alignment device is moved laterally, the lower case and the frame of the stock alignment device are supported by the frame of the stock alignment device with the relative movement of the binding drive shaft in the axial direction restricted. The fixed upper case laterally moves in the axial direction together with the lower stock alignment drive shaft and the upper stock alignment drive shaft supported by these two cases. Even if the lower stock alignment drive shaft moves laterally, the output bevel gear that meshes with the input bevel gear also shifts along the binding drive shaft, so the transmission from the binding drive shaft to the lower stock alignment drive shaft via the bevel gear always changes. It will be done in a dry state.

Furthermore, since the binding drive shaft is located below the binding space, the stock alignment drive shaft becomes longer, and when the stock alignment device is moved laterally, the stock alignment drive shaft is beveled to the lower part of the stock alignment drive shaft and the stock alignment drive shaft. Even if misalignment occurs with the upper part of the stock alignment drive shaft that is linked to the alignment device, the lower case moves slightly in the direction along the plane orthogonal to the axis of the binding drive shaft, and the lower stock alignment drive is performed. The axis orientation is adjusted, and the misalignment of the stock alignment drive shaft that occurs at the bottom and top is eliminated. Even if it is not completely eliminated, the universal joint absorbs the misalignment, and the increase in wear and the occurrence of transmission failure can be suppressed as much as possible.

〔The invention's effect〕

In this way, the power on the machine side can be efficiently and stably transmitted to the stock-adjusting device that can move laterally, so there is no need to provide an independent power source such as a motor in the stock-adjusting device. The cost of the waste straw processing unit was reduced.
