Agricultural machinery

Abstract

To provide agricultural machinery that can improve safety. [Solution] When the limit switch 123 of the detection unit 23 is turned ON, the control unit of the agricultural machine 1 sets the descent stop flag to the ON state, which restricts the descent of the supply container support 11 by the hydraulic cylinder 12a of the drive unit 12. After this setting, the control unit releases the ON state of the descent stop flag only when it does not receive signals from the operation units 26, 27, and 28 and the limit switch 123 of the detection unit 23 is turned OFF.

Claims

1. A movable support for supporting the crop storage unit, A drive unit for operating the support, A detection unit that can enter a detection state and a non-detection state, A control unit operated by the operator, The system includes a control unit that controls the drive unit, The control unit, When the detection unit enters the detection state, it is set to an operation restriction state that restricts the operation of the support by the drive unit. After the above setting, the operation restriction state is released only if no signal is received from the operation unit and the detection unit enters the non-detection state. A farming machine characterized by the following features.

2. A movable support for supporting the crop storage unit, A drive unit for operating the support, Multiple control units operated by the operator, The system includes a control unit that controls the drive unit, The control unit, When a signal is received from one of the multiple operating units, and another signal different from the first signal is received from one of the other operating units, the drive unit is set to an operation restriction state that restricts the operation of the support. After the above setting, the operation restriction state is released only if both the first signal and the other signal are no longer received. A farming machine characterized by the following features.

3. The detection unit enters a detection state when the support is positioned in a predetermined location, and also enters a detection state when operated by an operator. The agricultural implement according to feature 1.

4. The support is capable of rotating vertically about the pivot axis. The detection unit is positioned below the rotational axis. The agricultural implement according to claim 1 or 3, characterized by the features described herein.

5. The detection unit is, A rotating body having an elongated portion, A biasing body that biases the aforementioned rotating body, It has a detection body that can be in a detected state and a non-detected state, When the rotating body rotates in one direction against the biasing force of the biasing body, the detection body enters the detection state. When the rotating body rotates in another direction due to the biasing force of the biasing body, the sensing body becomes the non-detection state. The agricultural implement according to claim 1 or 3, characterized by the features described herein.

6. The biasing element is positioned on one end of the rotating body. The detection element is located on the other end side of the rotating body. The agricultural implement according to feature 5.
