A pressure receiving member 17 is vertically swingably attached to the machine wall via a pressure receiving member 17, and its free end side is located at the end of the waste straw conveying device 7 and closer to the plant head than the conveying device 7. As shown in FIG. 4, the boss 18 holding one end of the rotary support shaft 16 is configured to be rotatable, and the boss 18 only rotates in the upward direction of the pressure receiving member relative to the rotary support shaft 16. A clutch mechanism 19 is provided between the rotation support shaft 16 and the boss 18 to allow transmission and independent rotation of the rotation support shaft 16. A coil spring 22 that swings and biases the pressure receiving member 17 in the downward direction is stretched over a bracket 20 that extends integrally from the boss 18 and an arm 21 that extends integrally and rotatably from the rotation support shaft 16. It has been done. Then, the pressure receiving member 1
7 to the appropriateness detection device for each of the two paths 9, 11, that is, the paths 9, 11 are operated against the restoring force of the spring 22 due to the pressing force of the waste straw accompanying clogging of the waste straw in each path 9, 11. It is designed to change its position from the position where it is raised and retreated. As shown in FIG. 4, a member 25 is attached to the rotational support shaft 16 so as to be able to freely swing integrally thereto, and the sensor 26 detects the backward swinging of the pressure receiving member 17 by contacting the swinging member 25. A permanently open switch is provided. The switch 26 is attached to the boss bracket 20 and is connected to the pressure receiving member 17.
By simply changing the position of the switch 26, the switch 26 is also changed into a proper detection device, that is, a position where the positional relationship with the switch operating member 25 is proper.

にしてある。 As shown in FIG. 1, the pressure-receiving member 17 is also used as an upper guide for each of the paths 9 and 11, so that the stock side of the waste straw fed onto the cutters of the shredding device 8 is It is pressed against the cutter side by the biasing force. In other words, by pressing the stock side, which takes longer to cut than the tip side because of its bulk, the cutting can be done as quickly as possible.

れるように設けてある事を特徴とする。 In summary, the present invention provides the above-mentioned threshing machine, in which the pressure receiving member 1, which constitutes the detection device 13, retreats against the restoring force due to the pressing force of the waste straw.
7 is repositionably provided at the appropriate detection position of each of the paths 9 and 11, and the pressure receiving member 17
The sensor 26 that detects the retreat of the pressure member 17
It is characterized in that the detection position is changed to an appropriate detection position in conjunction with a change in the position of the detection position.

精度良い検出を容易に行えるようになつた。 That is, since the same pressure receiving member 17 and sensor 26 can be used to predict or detect straw clogging during shredded discharge, the configuration of the detection device for the prediction or detection can be simplified. Moreover, since the position of the sensor 26 is changed in conjunction with the change in the position of the pressure receiving member 17, when the sensor 26 is fixed, both the shredded straw and the long straw can be discharged. If the interlocking configurations of the 17 and 26 are different, the play or resistance in the interlocking system will be different, or if the positions of the pressure receiving member 17 and the sensor 26 are changed separately, it may be difficult to maintain a constant interlocking accuracy. Therefore, it is now possible to easily perform accurate detection both during shredding and when releasing long straw.
