It is fixed on side plate, and it is coaxially connected between the central shaft and rotary shaft of angular displacement sensor.
Torsion spring draw-in groove is equipped with described fixed plate and rotary shaft, the two ends of torsion spring are respectively placed in fixed plate and rotary shaft
Torsion spring draw-in groove in.
The rotary shaft is provided with blind hole towards the end face of angular displacement sensor one end, and the central shaft of angular displacement sensor is put
Enter blind hole, and be fixedly connected by fastening bolt.
Mounting hole is provided with described fixed plate, cutterhead height detecting device is fixed on by the mounting hole in fixed plate
On sugarcane guide plate.
Beneficial effect
1st, cutterhead height detecting device of the invention, its swing arm swings up and down with surface relief, is connected with swing arm
Rotary shaft is connected with angular displacement sensor, and the angle angle of swing arm and vertical direction can be gone out with real-time detection, and then by swing arm
Effective length and goniometer calculate actual height of the cutterhead apart from ground, efficiently solve the test problems of cutterhead height.
2nd, cutterhead height detecting device of the invention, is in dragged state, even if lower end when its swing arm is advanced with vehicle body
Rubber wheel is wound by sugarcane leaf, weeds or mud, or even can not rotate, and now rubber wheel is in dragged state, still will not shadow
The swing of swing arm is rung, detection means also can well work, can normally be detected.
3rd, cutterhead height detecting device of the invention, the rolling bearing of its swing arm upper end only carries one of swing arm and wheel
Point Action of Gravity Field, therefore radial load very little suffered by bearing and more constant, can effectively increase the service life.
