Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figure 1-4The present embodiment provides an unmanned agricultural machinery vehicle-mounted radar, comprising a housing 100, the surface of which is inlaid with a vehicle radar module 106, the top of which is rotatably connected to a C-shaped frame 200 adapted to the surface of the housing 100, the inner arc surface of the C-shaped frame 200 is provided with two sets of corresponding slots 206, the inner cavity of the slot 206 is fixedly connected with a rubber strip 205, one side of the rubber strip 205 is in contact with the surface of the housing 100, and the interior of the housing 100 is provided with a C-shaped frame 200 adapted to the surface of the housing 100. The rotating assembly of the C-shaped frame 200 includes a fixed plate 302 fixedly arranged in the inner cavity of the shell 100, a single-chip microcomputer 300 is arranged on the top of the fixed plate 302, wherein the model of the single-chip microcomputer 300 is STC89C51, a servo 301 is arranged inside the shell 100 and below the fixed plate 302, and the output shaft of the servo 301 extends downward to the outside of the shell 100 and is fixedly connected to a connecting ring 400, which is fixedly connected to a lower part of the C-shaped frame 200. On the end surface, the surface of the vehicle radar module 106 is embedded with an infrared sensor 203, wherein the model of the infrared sensor 203 is GP2Y1010AU0F. The signal output end of the infrared sensor 203 is electrically connected to the signal input end of the single-chip microcomputer 300 via a wire, and the signal output end of the single-chip microcomputer 300 is electrically connected to the signal output end of the servo 301 via a wire. Due to the configuration of the C-shaped frame 200 and the rotating assembly, when the surface of the vehicle radar module 106 is covered with a layer of dust, the dust absorbs, scatters, or reflects the infrared rays emitted by the infrared sensor 203 embedded in the surface of the vehicle radar module 106, thereby causing the voltage at the signal end of the infrared sensor 203 to change. The single-chip microcomputer 300 recognizes the voltage change and controls the servo 301 to rotate, driving the rubber strip 205 installed on the inner arc surface of the C-shaped frame 200 to scrape off the dust attached to the surface of the vehicle radar module 106, thereby preventing the dust from affecting the signal transmission and reception of the vehicle radar module 106.

[0023] Furthermore, a connecting groove 207 is provided on the surface of the C-shaped frame 200, and a connecting block 201 is clamped in the inner cavity of the connecting groove 207. A cleaning strip 208 is adhered to the surface of the connecting block 201, and one end of the cleaning strip 208 passes through the C-shaped frame 200 and is close to the surface of the shell 100.

A first bolt 105 is fixedly installed on one side of the abutment block 107. One end of the first bolt 105 passes through the connecting column 101 in sequence and extends to the outside of the other group of fixing columns 102. The other end of the first bolt 105 is threadedly connected to a nut 104, which is convenient for the staff to adjust the detection angle of the detection end of the vehicle radar module 106 according to the installation height.

[0027] Working principle;

[0028] First, the device is fixedly installed on the unmanned agricultural machinery, and the data parameters of the single-chip microcomputer 300 and the rotation angle of the servo 301 are adjusted according to actual conditions. Then, the nut 104 is loosened and the detection angle of the detection end of the vehicle radar module 106 is adjusted according to the installation height. When the adjustment is completed, the nut 104 is tightened so that the abutment block 107 abuts the surface of the connecting column 101, thereby fixing the housing 100. When the surface of the vehicle radar module 106 is covered with a layer of dust, the dust absorbs, scatters, or reflects the infrared light emitted by the infrared sensor 203 embedded in the surface of the vehicle radar module 106. The voltage at the signal end of the infrared sensor 203 changes, and the single-chip microcomputer 300 recognizes the voltage change and controls the servo 301 to rotate, thereby driving the rubber strip 205 installed on the inner curved surface of the C-shaped frame 200 to scrape the dust attached to the surface of the vehicle radar module 106. When the scraping is completed, it automatically resets, thereby preventing the dust from affecting the signal transmission and reception of the vehicle-mounted radar.
