Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a binding machine for threshed culms, and can be used for combine harvesters and the like.

(Prior art)

The prior art has the following configuration. That is, a feeding device is provided to transport the threshed culm to the binding machine in a sideways posture,
At the base side of the binding machine, there is provided a stock alignment plate that slaps the end surface of the explanted culm in the middle of transport while swinging in the direction of the culm, and moves only this collated plate toward the culm of the excreted culm. It was a configuration to adjust. The binding machine was not provided with a support guide for supporting and carrying the root portion of the culm at a position near the stock plate.

In addition, the invention of Japanese Utility Model No. 1-105427 as the invention of the prior application,
The swinging stock plate is provided with a guide plate that supports the root portion of the culm and guides it while swinging integrally.

In addition, the invention of Japanese Utility Model Laid-Open No. 62-196638 discloses that, on the root side of the threshed culm, a root liner for striking the rim side end and a support guide for supporting the root side of the culm. Is provided.

[Problems to be solved by the invention]

In the combine work performed by attaching the binding machine to the combine, the culms threshed by the threshing device are sent to the tying device by the feeding device in a sideways posture, and the culms in the middle of being fed are the end faces of the stock. Are aligned while being beaten with the stock alignment plate, a predetermined position in the stem direction is bound at a predetermined bundle diameter, and the bundle is released by the release rod.

At this time, the root portion of the culm being transported is detected by the culm position sensor provided in the preceding stage of the sending device, and based on the detection result, the root end surfaces of the tying device and the culm are aligned. The stock alignment plate is moved and adjusted in the direction of the culm, so that the proper position of the culm with respect to the culm length is tied and the stock alignment plate is used so that the end surface of the culm is well aligned. It is beaten with a board and aligned.

However, if the culm length is long, there is no supporting guide for receiving the base of the stock near the stock plate, so the base of the stock will be in a lowered state, When the end face is hit with a stock aligning plate, the base of the stock is bent, and the end face of the stem of the culm becomes poor, which may result in poor binding, poor release of the binding bundle, and the like.

Further, in the invention of the aforementioned Japanese Utility Model Laid-Open No. 1-105427, the guide plate for guiding the root portion of the culm is attached so as to swing integrally with the stock alignment plate. While guiding the plant base with the board, the base end of the lowermost excreted culm swings in the direction of the culm at the end of the guide plate on the bundling device side, disturbing it, and the stock alignment action cannot be performed well There was a problem.

In addition, the invention of Japanese Utility Model Laid-Open No. 62-196638 discloses that, on the root side of the threshed culm, a root liner for striking the rim side end and a support guide for supporting the root side of the culm. The base plate is configured to swing in the culm direction with the rear part as a fulcrum, so that the stock swinging action can be expected by swinging greatly at the transport start end side, but only small at the transport end side. There was a problem that the strain was unable to move, and the stock-sorting action was insufficient.

In view of this, the present invention provides a bundling device that reciprocates and swings in the direction of the culm body while maintaining the stock alignment plate in a substantially parallel state with respect to a support guide that supports and guides the base of the culm from below. While maintaining the relationship between the support guide and the stock alignment plate in a predetermined state, while maintaining good alignment of the stock during the process from the transport start end side to the end side, It is intended to eliminate the drawbacks of the conventional apparatus by adjusting and controlling the length of the culm according to the length of the culm while maintaining the transportation of the stock side in a stable state.

[Means for solving the problem]

The present invention relates to a feeding device 27 for transporting a threshed culm in a sideways posture after threshing, a bundling device 1 for bundling the culm fed by the infeed device 27, and a stationary device attached to a stocking frame 36. And is located at a position closer to the tip end side by a predetermined distance from the base end of the culm in a sideways posture during conveyance by the feeding device 27, and supports and guides the culm part of the culm from below. The support guide body 3 along the carrying direction to be carried out, and is supported by the stock assortment frame 36, and is provided corresponding to the base side end of the culm being carried by the feeding device 27, A stock aligning plate 2 that reciprocally swings and taps in the direction of the culm while keeping the end face of the stem of the culm substantially parallel to the longitudinal direction of the support guide 3.
A culm position sensor 29 that is located near the stock plate 2 and detects a culm position of the culm being conveyed by the feeding device 27;
Based on the detection results of the culm position sensor 29 and the culm sensor 33, the stock culm 2 and the support guide 3 are integrally integrated with the culm of the culm. And a movement adjusting means for adjusting the movement in the body direction and a binding machine for threshed culms.

[Function of the invention]

In a harvesting operation in which a combiner is mounted on a combine and harvesting, threshing, and bundling culms are performed, when the culm in the sideways posture that has been threshed by the threshing device is transported by the feeding device, the stocking frame 36 In the supporting guide body 3 which is supported in a stationary state, a portion of the excreted culm which is closer to the tip side by a predetermined distance from the base end of the culm is supported from below, and is disturbed by the supporting guide body 3 in the culm body direction. The root end face of the culm supported by the support guide 3 smoothly reciprocates in the culm body direction while being substantially parallel to the longitudinal direction of the support guide 3. While being conveyed from the transport start end side to the transport end side, the stock is aligned and sent to the binding device 1 while being transported from the transport start end side to the binding device 1, and bound by the binding device 1 at a predetermined culm position for each predetermined bundle diameter. You.

Then, the bound culm bundle is released to the outside of the machine.The root of the culm is detected by the culm position sensor 29, and the tip of the culm is detected by the culm sensor 33. Based on the detection result, the swinging stock plate 2 and the stationary supporting guide 3 are simultaneously moved and adjusted in the culm direction of the culm of the culm while maintaining the predetermined relational position, so that the culm length is shortened. , The base end faces are aligned well and bound by the binding device 1.

〔The invention's effect〕

According to the present invention, the support guide body 3 that guides while supporting the root portion of the culm in a stationary state while transporting the culm in a state where the spike side of the culm is detected by the culm sensor 33, and the support While maintaining a substantially parallel state with respect to the longitudinal direction of the guide body 3 and reciprocatingly swinging, the relative position of the stock alignment plate 2 which is aligned by hitting the base end face of the culm is constantly maintained in a constant relation. By adjusting the movement in the direction, the support of the root portion of the culm and the action of aligning the stock are stabilized, and the stocking from the transport start end side to the transport end side of the feeding device 27 is prevented while preventing the stock root side from sagging. The stock alignment action of the plate 2 becomes accurate, the alignment of the roots of the culms becomes good, and poor tying of the culms and poor release can be reduced.
