[0041] Refer to the instructions attached Figure 1-5 , The screw rod 7 is driven to rotate by the output end of the motor 5, and the screw rod 7 drives the sliding block 24 to slide to the right, so that the animal material box 9 is moved to the right through the support plate 13. When the material box 9 moves to the right, the spring 143 Under the force of, the inner rod 142 will slide down, thereby driving the support plate 13 and the material box 9 to move downwards. The material box 9 moves to the right while moving down to the inside of the lime powder. At this time, the output end of the electric push rod 12 The rubber plug 11 is driven to move upwards, and negative pressure is formed inside the material box 9. Under the action of the pressure difference, the lime powder is pressed into the material box 9 through the inlet, so as to realize the sampling of the lime powder, and then the motor 5 is reversed. Drive the sliding plate 6, the support plate 13 and the material box 9 to move to the left. At this time, the bump 15 will squeeze the guide rod 16 during the movement, thereby driving the support plate 13 and the material box 9 to move upward, making the material box 9 move to the left Move upward while moving, and the material box 9 is moved while sampling through the electric push rod 12, which can expand the sampling range;
[0042] Refer to the instructions attached figure 1 with 6 When the vehicle approaches the frame 2, the proximity sensor 22 converts the analog signal into an electrical signal and transmits it to the A/D converter, and the A/D converter transmits the digital signal to the PLC controller 23 for analysis and processing, and then the processed data It is transmitted to the D/A converter to control the work of the motor 5 and the electric push rod 12 through the D/A converter.
