Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an improvement of a grain culm binding device mounted on an agricultural machine such as a combine harvester.

[Problems that conventional technology and ideas try to solve]

Generally, when a combine harvester is equipped with a binding device for bundling a certain amount of empty grain culms after reaping and threshing and tying them with string, the binding device is driven by power transmission from the power source of the combine. However, in this case, the power transmission section from the power source to the binding device in the combine is
Depending on the combine, there are times when it is installed on the right side and times when it is installed on the left side.

Therefore, in the bundling device, the power input section to the bundling device can be divided into a right-handed one provided on the right side and a left-handed one provided on the left side, in accordance with the position of the power transmission section on the combine harvester side. The problem was that two types of binding devices had to be designed and manufactured, resulting in a significant increase in costs.

The object of the present invention is to provide a binding device that eliminates this problem.

[Means to solve the problem]

In order to achieve this purpose, the present invention has a nodule and a swinging discharger on one side of the left and right sides of a transmission case attached to an agricultural machine such as a combine harvester, with the grain culm conveyor in between. In a binding device in which a packer and a needle are each attached to an arm on the other side, a power input shaft to the binding device is provided in the transmission case at a location outside the rotation locus of the discharge arm, packer, and needle. is supported so that both ends of the power input shaft protrude from both left and right sides of the transmission case, and a shaft coupling portion is provided at each end of the power input shaft so that it can be freely attached to and detached from the power transmission shaft from the agricultural machine side. I configured it.

[Operations and effects of the invention] With this configuration, when the power transmission shaft from the agricultural working machine side to the binding device is on the right side of the agricultural working machine, the power transmission shaft is connected to both the left and right ends of the power input shaft of the binding mechanism. The binding device can be driven by connecting to the right-most shaft joint, and when the power transmission shaft from the agricultural machine to the binding device is on the left side of the agricultural machine, the power transmission shaft The binding device can be driven by connecting the power input shaft of the binding mechanism to the left end joint of the left and right ends of the power input shaft of the binding mechanism.

Therefore, according to the present invention, power can be transmitted to the binding device without changing the structure of the binding device even when the power transmission shaft from the agricultural machine to the binding device is located on either the left or right side of the agricultural machine. In other words, the binding device can be configured into one type, and there is no need to use two types of binding devices, one for right-handed and one for left-handed, as in the prior art, resulting in a significant reduction in costs. It has the effect that can be achieved.
