Description

[Detailed Description of the Invention] The present invention is to provide a structure in which an incised strip-shaped body is held and conveyed to the threshing section straw 1 at the rear of the machine body in a sideways n posture, and the conveyance end side is located at one side of the machine body in an inclined state. A device for tying the endless rotating belt-shaped threshing machine in a horizontal position is arranged parallel or almost parallel to the lateral direction of the machine body, and the stock end alignment tool of the tying device is attached to the body of the tying device. A control mechanism is installed to automatically adjust the movement of the straw, so that the bundled waste straw is released as close to the mown field as possible, and the distance between the binding position and the tip is maintained regardless of changes in culm length. The present invention relates to a straw processing device for a threshing section of an in-line container, which is designed to maintain a substantially constant value and to ensure that a stock edge leveling tool acts on the grain.

In the above-mentioned waste straw processing equipment, the movement adjustment control of the stock leveling tool has conventionally been performed based on information from the culm length detection sensor for controlling the handling depth, so that a sufficient stock leveling effect has been achieved. Ranunakatsuhi. This is because in the case of the culm length sensor, the detection of the stock end position is performed from one side of the threshing section, so the transportation route for the grain culm from this detection position to the tying device becomes long, and In this case, positional deviation occurs due to transfer between conveyance devices, etc., and the product is not supplied to the binding device.
This is because the stock end of the removed straw may be separated from the leveling tool formed by the movable sub-tube f', and the leveling tool may not substantially work.

In addition to this, conventionally, the threshing part straw transported by the endless rotating belt is in a posture almost perpendicular to the endless rotating belt, so the endless rotating belt is The straw from the threshing section of the threshing section is supplied to the binding device in an inclined state where the stock side is ahead of the head side, and a force acts on the waste straw fed to the binding device to align it in the direction that is inclined with the culm. This is because, as a result, alignment defects are likely to occur. In addition, in order to prevent f'L, a device for conveying the tip side in parallel with the endless rotating belt is crotched in a state where the conveying speed is faster than the conveying speed of the endless rotating belt, Even if the threshing unit is configured so that the culm is parallel to the binding device when the straw is fed to the binding device, the threshing flask may separate from the conveying device and sometimes due to inertia. According to the present invention, the strainer of the present invention moves in the direction of the culm and is supplied to the tying device, and the straining of the waste straw is separated from the adjusting tool which has been adjusted to move, resulting in the adjusting tool not working. The purpose is to ensure that the stock end alignment tool works reliably regardless of changes in culm length and to obtain a sufficient stock alignment effect, and to provide a simple structure for this purpose. ◇The characteristic configuration of the present invention is as follows:
In the straw processing device of the threshing section of the combine harvester mentioned above, 1
[1] In order to control the movement of the stock end aligning tool, the sensor for detecting the entire position of the straw stock end with respect to the tying device is of a contact type, and the threshing unit is provided at the conveyance terminal end of the endless rotating belt. The function and effects of the present invention are as follows, since it is arranged in a position that acts on the plant base side of the straw strip.

In other words, if the sensor is made of a contact type and is placed at the end of the conveyance of the endless rotating belt-like body closer to the stock end than the endless rotating belt-shaped body, the detection of the stock end position can be easily performed. Fix the equipment! 171, and the threshing section straw that is 1 lfl from the Muda M rotating belt is parallel to the binding MK, that is, the tip side, which is transported later than the stock head side, is the stock head side. As if trying to catch up with the side,
In a certain IAFi, a sensor provides movement resistance on the stock side so that the straw in the threshing section that separates from the conveyance device does not move due to inertia. Therefore, the position of the end of the waste straw stock relative to the binding device can be detected with high accuracy, and
It is possible to correct the posture of the straw in the threshing section when it separates from the endless rotating band, and to prevent misalignment, and the alignment tool works reliably regardless of changes in culm length, allowing for extremely accurate stock edge alignment. I was able to do so. Moreover, the sensor can be effectively used for the above-mentioned attitude correction and positional misalignment prevention, and the structure is simple and economically advantageous.
