という問題があった。However, due to the structure of the combine, the herbaceous plant and the culm raising device are arranged in an inclined manner such that the lower end side thereof is in front of the traveling direction of the traveling body, and the herbaceous body goes to the upper end thereof. In accordance with the above, the inclination angle is sharp so as to approach the front of the device for raising the grain stem.
In addition, in the case of the ultrasonic sensor, it is necessary to install the ultrasonic sensor at a height position that is far away from the ground to be measured in order to sufficiently ensure measurement accuracy. In order to take enough height, if an ultrasonic sensor is installed on the upper end side of the back of the herbaceous body, the transmitted wave and / or the received wave of the ultrasonic sensor tend to interfere with the tine caused by the culm causing device, Momentum, the installation location of the ultrasonic sensor is caused by raising the grain culm and it is installed at a low position away from the device, which has the disadvantage that measurement accuracy cannot be sufficiently ensured, and the installation location is also limited. there were.
