センサー構造に関する。[Detailed description of the invention] [Industrial application field] The present invention uses a transmitter that emits ultrasonic waves toward the ground to detect the height of the reaping device above the ground in order to control the cutting height. The present invention relates to a sensor structure for a reaping harvester equipped with an ultrasonic sensor consisting of a receiver for receiving the reflected waves.

Conventionally, in the above-mentioned reaping and harvesting machine, the transmitter and the receiver have been arranged side by side in the lateral direction of the machine body, which has caused the following disadvantages.

があつた。
In the case of the above-mentioned ultrasonic sensor, the detection target range is the overlap between the sound wave projectable range and the sound wave receivable range on the ground. For this reason, depending on the placement of the transmitter and receiver, the overlapping range may become elongated in the longitudinal direction of the aircraft, and if there are footprints left in the field from planting seedlings, etc., the detection target area may become elongated. In some cases, the height of the reaping device was detected to be high because the height of the reaping device coincided with the footprint recess and the entire part fell into this recess.

できるようにすることにある。 The purpose of this invention is to avoid detection based on the inside of the dent, even if the detection range by the ultrasonic sensor becomes elongated, or even if the detection range matches the remaining footprint dent. The goal is to make it possible.

The characteristic configuration of the present invention is that in the above-mentioned sensor structure of the reaping and harvesting machine, the transmitter and the receiver are arranged in the longitudinal direction of the machine body, and the functions and effects thereof are as follows.
地面上における音波投射可能範囲と音波受信可

Even if the overlap range of the sound wave projectable range and the sound wave reception range on the ground is elongated, the arrangement of the transmitter and receiver in the longitudinal direction of the aircraft makes the longitudinal direction of the overlap range the lateral direction of the aircraft. However, even if the detection target range matches the footprint recess, since the footprint recess is generally elongated in the longitudinal direction of the aircraft, a part of the detection target range will be located outside the recess.

Even if the detection target range becomes elongated and matches the remaining footprint dent, part of the detection range is located outside the dent, thereby avoiding height detection based on the inside of the dent. This has made it possible to obtain a highly accurate finish in which the cutting height does not change due to the shape of the detection target area or footprint depressions.
