問題を解消せんとするものである。To explain in more detail, the above-mentioned reaper can operate automatically regardless of unevenness in the field or pitching of the vehicle body. It is designed to make it possible to maintain a constant cutting height, and also to maintain the height of the cutting device above the ground. Since the detection is performed without contacting the ground using wave energy, it can be used successfully for a long period of time without trouble due to damage. If foreign matter adheres to the outer surface or the receiving outer surface Vc of the receiver, there is a risk that the receiver will emit information that is significantly different from the actual height above the ground, resulting in malfunction. This is an attempt to solve such problems.

Detailed Description of the Invention [Field of Industrial Application] The present invention provides a sensor for detecting the height above the ground of a reaping processing section that is attached to a vehicle body so as to be able to rise and lower. The present invention relates to a cutting height control device for a reaping harvester, which is provided with a control mechanism that is attached to a side part and that automatically raises and lowers the reaping processing section to maintain it at an appropriate height based on information from the sensor. [Prior Art] The reaping and harvesting machine described above is configured to be able to operate while maintaining a substantially constant cutting height through the action of a control mechanism, regardless of pitching of the vehicle body. Conventionally, in this type of seed reaping harvester, the sensor for detecting the height of the reaping processing section above the ground is of a ground type, which has the following disadvantages. [Problems to be solved by the invention] In wet rice fields, sensors are given a ground biasing force, and a grain tank is often installed on the driver's side of the car body. Due to the weight of the stored grain, the traveling equipment tends to sink by a large amount, and the sensor is pushed deeply or strongly into the field, causing insufficient lifting of the reaping processing section by automatic control, resulting in lower cutting height. If the height becomes lower than the set height, mud may adhere to the lifting device and cutting blade located on the driver's side of the reaping processing unit, making it more likely to malfunction, or the sensor itself may become deformed or damaged. For this reason, in wet rice fields, even if automatic control was performed, the cutting heights would not be the same, and automatic control had to be stopped to prevent equipment failure or damage. If the control is performed properly, even in wet fields where mud tends to adhere easily, automatic control can be activated to prevent mud from adhering to the cutting area while cutting crops close to the field. Therefore, it is extremely advantageous to be able to use automatic control in wet fields.However, in reality, sensor failures and poor control are likely to occur, making it impossible to activate automatic control, resulting in extremely low cutting heights. The finish deteriorates due to thickening or unevenness, or equipment failure due to adhesion of muddy soil is likely to occur.The purpose of the present invention is to provide a reaping harvester that can perform automatic control as desired even in wet fields. [Means for Solving the Problems] The characteristic configuration of the present invention is that in the above-mentioned cutting height control device for a reaping and harvesting machine, the sensor includes a transmitter that projects wave energy toward the ground; It consists of a receiver that receives the wave energy reflected from the ground,
Its action and effects are as follows. [Operation] The sensor uses wave energy to detect height without contacting the ground, so even if the traveling device sinks, it will not be pressed against the field, and height detection can be performed accurately and reliably. To ensure that the reaping processing section is maintained at an appropriate height by performing automatic control so that the lifting height of the reaping processing section is not insufficient. [Effects of the invention] The sensor is not pressed against the field regardless of the subsidence of the vehicle body, and the reaping processing section is reliably maintained at a predetermined appropriate height. It is now possible to perform m-motion control without causing damage, failure, or control failure, and it is now possible to obtain a highly accurate work finish with the cutting height as uniform as possible, regardless of whether the field is dry or wet. Moreover, equipment failures caused by mud adhesion can now be easily avoided. [Example] As shown in Figs. 1 and 2, a crawler traveling device (1
), a threshing device (3) that pinches and conveys the stem culms to the rear using a side feed chain (2), and a driver's seat (4). A reaping processing unit is provided, which includes a device (5) for pulling up the planted stem culm, a cutting blade (6) for cutting the base of the pulled-up stem culm, a device (7) for transporting the cut stem culm backwards, etc. Thus, as the field progresses, the stem culms planted in the field are raised and harvested, and the harvested stem culms are sequentially handled and processed in a continuous manner automatically. Note that this combine harvester is normally set to perform round-cutting work with the uncut stems positioned on the left-lateral side of the machine body. The support frame (8) of the reaping processing section is provided with respect to the vehicle body so that it can be swung around the horizontal axis (X) by a hydraulic cylinder (9), and as shown in FIG. A transmitter (1) that projects light as wave energy toward

It is assembled into the sensor case (11) which is fixed in place. The receiver (10b) is configured to extract fluctuations in the amount of light received as fluctuations in voltage value, and as shown in FIG. 12), a setting device (13) for setting the appropriate height above the ground of the reaping processing section as a voltage value, and the width increasing circuit (12).

If the height above the ground of the reaping processing section is above the appropriate height above the ground, the hydraulic cylinder (9) is operated to automatically lower the reaping processing section, while lowering the reaping processing section to the appropriate height. It is configured so that it can be maintained. In short, the transmitter (LOA) and the receiver (10b)
) constitutes a sensor for detecting the height of the reaping processing unit above the ground, and automatically raises and lowers the reaping processing unit to maintain it at an appropriate height based on information from the receiver (10b).

4), and the transmitter (10a)
The alarm lamp (19) is turned on to notify a worker that foreign matter such as muddy water has adhered to the transmitting outer surface (Sa) of the receiver (10b) or the receiving outer surface (Sb) of the receiver (10b). It is. Further, the discriminating circuit (14) is connected to a manually operated lifting state switching mechanism (20) for switching the valve driving circuit (16) to a lifting operation state, an lifting stop state, and a lowering operation state. The circuit (16) is configured to be able to be switched and connected to the circuit (16) in a reverse manner using a manually operated changeover switch (21). automatically raising and lowering the
It is configured so that a state in which the reaping processing section is artificially raised or lowered can be selected using an elevation state switching mechanism (20). In carrying out the present invention, when the discrimination circuit (18) discriminates that the signal value output from the amplification circuit (12) is out of the change range, the changeover switch (21) It is convenient to have a configuration in which the automatic lifting is automatically stopped at the same time as the above-mentioned alarm is issued, such as by providing a drive mechanism that automatically switches the elevator to the state in which it is connected to the lifting state switching mechanism (20). good. Furthermore, in the above embodiment, light is used as wave energy, but for example, an ultrasonic wave projected toward the ground from the transmitter (10a) is reflected from the ground and transmitted to the receiver (10b).
Other configurations may also be used, such as a configuration in which the height above the ground is detected based on the time fluctuation required until it is received. Furthermore, in the above embodiment, the change state of the information from the receiver (10b) is configured to be detected based on the fact that the absolute value of the information is out of the set range. However, other configurations may be used, such as a configuration in which the detection is performed based on the fact that the rate of change of information is out of a set range. Further, in the above embodiment, the alarm lamp (19) is used as an example of constructing the alarm mechanism, but the alarm mechanism may also be implemented in a uniform configuration using an alarm buzzer. Further, in carrying out the present invention, a transmitter (10a) and a receiver (
