Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a culm bundling device equipped on a harvester (moving threshing device) having a threshing device mounted on a traveling platform,
More specifically, the present invention relates to a culm bundling device whose bundling position can be adjusted according to the culm length of the culm discharged from the threshing device.

[Prior art]

This type, the culm bundling device equipped in the threshing device for harvesters, for example, as shown in Japanese Utility Model Publication No. 61-74334,
It is slidably fixed on a lower parallel rail fixed to the thresher side. However, with the support of only the parallel rails, the culm binding devices provided above and below the culm binding passage are in a cantilevered state, so that the space between the threshing device and the culm binding device is further increased. Are connected by a fixed stay in a direction intersecting with the parallel rails, and a structure for preventing the tilting of the drainage tying and bundling device is adopted.

[Problems to be solved by the invention]

However, although the culm binding device moves along the axis on the parallel rails, the support by the fixed stays fixed in the direction intersecting the parallel rails causes the fixed stays to move along with the movement of the binding device. Since an unreasonable load acts, as a countermeasure against this, the upper pipe stay in the direction parallel to the parallel rails is fixed to the culm binding device side, and this upper pipe stay is provided on the binding device side of the fixed stay and is deformable. It has a structure in which it is sandwiched between an elastic material and a rollable roller, but since the binding device itself is an intermittent drive system that operates a certain amount of culm, vibration due to intermittent drive of the packer or discharge arm is This is because the elastic material that regulates the upper pipe stay is deformed, so that the lengthwise support by the fixed stay becomes unstable, and tilting of the culm bundling device cannot be prevented. Drawback has been made.

Therefore, the present invention has been made in view of the above-mentioned conventional circumstances to solve the problem, and is a direction intersecting with the moving direction of the culm binding device that connects the threshing device and the culm binding device. The present invention is implemented for the purpose of providing a drainage binding device capable of rotating the stay in conjunction with movement of the drainage binding device.

[Means for solving problems]

The present invention that achieves the above object is to fix a rail along the culm direction of the culm on the side of the threshing device, and between the upper part of the culm bundling device that slidably moves on the rail and the threshing device. A stay connected to the rail in a direction intersecting with the direction in which the rail is arranged is provided, one end of the stay is pivotally supported on a vertical axis fixed to either the culm binding device or the thresher device, and the other end is culled. Predetermined sliding resistance between the brace fixed to either the bundling device or the threshing device through the long hole along the length direction of the stay provided on either the stay side or the bracket side. Are connected by a vertical tightening tool that is crimped with, and the stay is interlocked with the movement of the culm binding device.
It is formed by oscillating and slidingly moving in the longitudinal direction about the vertical axis.

[Action]

Therefore, between the upper cover 24 of the culm bundling device 10 and the bracket 43 of the threshing device 3, the rails 35, 36 arranged along the culm direction of the culm discharged from the threshing device 3 are provided. Even in the case of connecting the stays 44 arranged in a direction intersecting the arrangement direction, when the culm binding device 10 is moved back and forth by rotating the adjusting handle 40, the binding position is changed. The stay 44 swings in the direction of the arrow about the longitudinal axis 41 in the interlocking movement of the stay 44 and slides in the length direction through the long hole 45, so that an unreasonable load acts on the stay 44. The entire bundling device 10 can be smoothly moved.

Since the stay 44 or the long hole side of the bracket 43 is crimped in the vertical direction with a predetermined sliding resistance to the bracket 43 via the fastener 46, the stay 44 or the bracket 43 can be intermittently driven. Therefore, the vibration of the culm tying and binding device (10) that is generated thereby is reliably prevented.
