Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention provides a waste straw shredding device that shreds a threshing discharge straw behind a threshing device, and a threshing discharge waste behind the waste straw shredding device. A waste straw supply path for transporting the straw discharge bundling device for treating the straw in a sideways posture, and the lid of the waste straw receiving port of the waste straw shredder for conveying the threshing waste straw from the threshing device in a sideways posture Switched between an ascending open position for feeding the conveyed discharge straws to the discharged straw shredding device and a lowered closed position for forming the bottom wall member of the discharge straw supply path and supplying the conveyed discharge straws to the discharged straw binding device. Collected by the stocker side contact sensor, the tip side contact sensor and the waste straw bundling device which are freely provided and are arranged in parallel in the stem direction so as to detect the stock end position of the conveyed straws in the waste straw supply path. Each of the stock aligning plates that strikes and align the stock ends of the threshing removal straws, A stock source side contact sensor, the tip side contact sensor and the stock aligning plate are provided with a drive mechanism for moving and adjusting the stock aligning plate in the same direction in the culm direction of the threshing discharge straw, and the stock end of the transport discharge straw is the stock. The drive mechanism is automatically operated based on the information from the stock origin side contact sensor and the tip side contact sensor so as to pass between the origin side contact sensor and the tip side contact sensor without contacting the stock source contact sensor. The present invention relates to a combine threshing and discharging straw device provided with a stock aligning plate position control mechanism to be operated.

[Conventional technology]

In the above-mentioned combine, conventionally, the stocker side contact sensor and the tip side contact sensor are arranged at a position located on the upper side or on the lower side of the supply switching tool of the exhaust straw supply path.

[Problems to be solved by the invention]

In the former case, that is, when the contact sensor is located on the upper side of the supply switching tool, in order to avoid the inconvenience that the stock alignment plate is unnecessarily moved and adjusted when shredding the discharged straw, The main switch is turned off so that the control is not performed, but sometimes the main switch was turned off while the stock alignment plate was moved and adjusted to the tip side. In the latter case, that is, when the contact sensor is located on the lower side of the supply switching tool, the threshing discharge straw does not come into contact with the contact sensor during the discharge straw shredding process. The sensor and the stock alignment plate are controlled to move toward the tip end to the stroke end. Therefore,
In both the former case and the latter case, when the processing of waste straw is switched from shredding to binding, the stock aligning plate should be moved to a proper position to strike the stock ends as the threshing waste straw reaches the contact sensor. Even if the control is started, if the threshing discharge straw is relatively long, the position adjustment of the stock aligning plate will be delayed and the threshing discharge straw will be caught at the edge of the stock aligning plate, resulting in disturbance of posture and clogging of the threshing discharge straw. was there.

An object of the present invention is to eliminate the above-mentioned inconvenience when switching the waste straw processing from shredding to binding, and to simplify the structure and the operation.

[Means for solving problems]

The characteristic configuration of the present invention is, in the above-mentioned combine threshing and discharging straw processing apparatus, the stock aligning plate is at the stroke end on the stock origin side, and the stock is in the state in which the lid is in the rising open position. At least the tip side contact sensor of the side contact sensor and the tip side contact sensor is in contact with the lid body, the stock alignment plate is at the tip end side stroke end, and the lid body in the rising open position. In a certain state, the stock origin side contact sensor and the tip side contact sensor are located at the point where the stock side contact sensor and the tip side contact sensor are arranged above the lid so that the tip side contact sensor contacts the lid. The action and effect are as follows.

[Work]

When the discharged straws come into contact with both the stock side contact sensor and the tip side contact sensor during the binding process of the discharged straws, the drive mechanism is operated to move both contact sensors and the stock alignment plate to the stock side, If the discharged straw does not contact with either the stock base side contact sensor or the tip side contact sensor, the drive mechanism is operated so as to move both contact sensors and the stock alignment plate toward the tip side. In other words, the drive mechanism is operated so that the transport and discharge straw comes into contact with only the tip side contact sensor.

Then, even when the stock aligning plate is located on the tip side when switching the straw processing from bundling to shredding, when the lid body is switched to the rising open position, the lid body detects both the sensor on the root side and the tip side. When the stroke end of the stock alignment plate side of the stock alignment plate is relatively distant to the machine lateral side from the end of the stock base side of the lid body, the stock alignment plate control mechanism contacts the Until the side contact sensor is disengaged from the lid, if the stroke end on the stock side of the stock alignment plate is near the end of the stock base side of the lid, the stock alignment plate is automatically moved until the stock alignment plate reaches the stroke end. Move operation. That is, the stock aligning plate position control mechanism automatically retracts and moves the stock aligning plate to the stock base side during the shredding process by switching the lid to the raised open position.

〔The invention's effect〕

Therefore, even when the stock aligning plate is located on the tip side when switching the waste straw processing from bundling to shredding, shredding processing can be performed by retracting it from this position to the stock base side. When switching the waste straw processing from shredding to bundling and performing the position control of the stock alignment plate, even if the length of the waste straw that is started to be supplied is longer than the length at the previous binding,
Moreover, even if the position adjustment of the stock aligning plate is delayed, the stock aligning plate is separated from the stock straw side to the base side of the stock, and it becomes possible to avoid the waste straw being caught on the stock aligning plate widely. Even if the process is switched from shredding to bundling, the process can be started without clogging or posture disturbance regardless of the length of the discharged straw.

Moreover, since the stock aligning plate is automatically retracted when the lid is switched, it is only necessary to operate the lid to switch the processing mode, which is advantageous in terms of operation. Became.

Moreover, by effectively utilizing the original position control of the stock aligning plate, which is the automatic retracting control of the stock aligning plate, it is possible to have a simple structure in which the sensor and the lid are arranged so that they can contact each other, which is economically advantageous. I was able to.
