[0025] See also Figures 2 to 5 and Figure 7 As shown, first guide blocks 20 are fixedly installed on both sides of the first rotating seat 17, and the first guide blocks 20 are slidably installed on the inner wall of the first guide groove 21. The first guide groove 21 is fixedly installed on the top of the identification seat 3, which can limit the moving trajectory of the first rotating seat 17, so that the movement of the first rotating seat 17 is smoother and more stable.

[0026] See also Figures 5 to 7 As shown, the bottom end of the slide plate 15 is symmetrically fixed with a second guide block 22, and the second guide blocks 22 are slidably installed on the inner wall of the second guide groove 23.

[0028] Embodiment 2 See also Figure 5 and Figure 7 As shown, compared with Example 1, as another embodiment of the present invention, the shock absorbing assembly includes a buffer plate 24 arranged at the bottom end of the rotating base 5, the buffer plate 24 is fixedly installed at the top end of the steering rod 4, the buffer plate 24 is connected to the rotating base 5 by a spring 25, and the spring 25 is evenly installed at the top end of the buffer plate 24. When the excavator body 1 is traveling on a muddy road section, the elastic potential energy can be accumulated through the arranged spring 25, thereby absorbing the vibration of the laser radar scanning device 6, avoiding the bumpy road that easily causes the excavator body 1 to be bumped when the excavator body 1 is dredging, thereby affecting the laser radar scanning device 6, causing unnecessary wear of the laser radar scanning device 6, and reducing the service life of the laser radar scanning device 6, reducing the vibration of the laser radar scanning device 6 when the excavator body 1 is traveling, thereby reducing the wear of the laser radar scanning device 6 and extending the service life of the laser radar scanning device 6.

[0029] See also Figure 7As shown, the springs 25 are all wound around the outer wall of the thick guide rod 26, and the thick guide rods 26 are all fixedly installed on the top of the buffer plate 24. The inner wall of the thick guide rod 26 is slidably installed with a thin guide rod 27, and the top of the thin guide rod 27 is all fixedly installed on the bottom end of the rotating base 5. The radius of the cross section of the thick guide rod 26 is relatively large, which can guide and protect the spring 25 when the spring 25 undergoes elastic deformation. The radius of the cross section of the thin guide rod 27 is relatively small, which can provide space for the rotating base 5 to move, and guide the vibration direction of the rotating base 5 by sliding on the inner wall of the thick guide rod 26.

[0030] See also Figures 5 to 7 As shown, the positioning assembly includes a connecting block 28 arranged on the inner wall of the blocking cover 7, and the maximum distance between the bottom end of the connecting block 28 and the top end of the rotating base 5 is equal to the maximum distance between the bottom end of the second rotating seat 19 and the top end of the identification seat 3. By setting the positioning assembly, when the laser radar scanning device 6 starts scanning and identifying, the connecting block 28 abuts against the top end of the rotating base 5, thereby squeezing the spring 25 until the connecting block 28 drives the rotating base 5 to move to abut against the guide thick rod 26, so that the position of the rotating base 5 is fixed and no longer shakes due to the spring 25, thereby improving the scanning and identification efficiency of the laser radar scanning device 6.

[0031] To sum up, by cooperating with the lifting assembly and the positioning assembly, when the lifting assembly drives the barrier cover 7 to move, it can drive the connecting block 28 to move through the barrier cover 7, and squeeze the rotating base 5 through the connecting block 28, so that the rotating base 5 and the laser radar scanning device 6 are quickly fixed in position and no longer shake due to the spring 25, thereby improving the working efficiency of the device. In addition, the lifting assembly intelligently slows down the output power when the connecting block 28 abuts against the rotating base 5, so that the operation of the positioning assembly is smoother.

[0032] See also Figures 5 to 7 As shown, a positioning block 29 is fixedly installed at the bottom of one end of the connecting block 28, and the bottom end of the positioning block 29 abuts against the inner wall of the positioning groove 30. The positioning groove 30 is arranged at the top of the rotating base 5, and can drive the positioning block 29 to abut against the inner wall of the positioning groove 30 when the connecting block 28 abuts against the rotating base 5, which can further improve the positioning efficiency of the positioning component, and when the laser radar scanning device 6 performs scanning and recognition operations, the steering rod 4 can drive the laser radar scanning device 6 to rotate through the buffer plate 24, the guide thick rod 26, the guide thin rod 27 and the rotating base 5, thereby improving the recognition effect of the laser radar scanning device 6.

[0033] See also Figures 5 to 7As shown, the two sides of the top of the positioning groove 30 are arranged to be inclined and extend outward, so that when the connecting block 28 drives the positioning block 29 to move to the inner wall of the positioning groove 30, the inclined portion at the top of the positioning groove 30 can make the positioning block 29 move into the positioning groove 30 more smoothly, thereby avoiding the problem of motion interference caused by the positioning block 29 abutting against the bottom end of the rotating base 5.

[0034] Working principle: When the excavator body 1 is transferred, the rough road surface easily causes the excavator body 1 to bump, so that the excavator body 1 drives the buffer plate 24 to bump through the control cabin 2 and the steering rod 4, and the buffer plate 24 squeezes the spring 25, causing the spring 25 to elastically deform and accumulate elastic potential energy, thereby reducing the vibration effect of the excavator body 1 on the rotating base 5; When the excavator body 1 moves to the target area and needs to identify the environment, the intelligent module installed in the control cabin 2 detects that the excavator body 1 is parked, and sends a signal to control the motor 14 to start. The motor 14 drives the second gear 13 to rotate, and the second gear 13 drives the first gear 12 to rotate. The first gear 12 drives the screw rod 10 to rotate, so that the screw rod 10 drives the lifting slide plate 9 to move downward along the guide rod 11, and the lifting slide plate 9 drives the barrier cover 7 to move. At the same time, the barrier cover 7 drives the second rotating seat 19 to move, and the second rotating seat 19 drives the connecting rod 18 to rotate, so that the connecting rod 18 drives the first rotating seat 17 to move along the first guide groove 21, and the first rotating seat 17 drives the telescopic rod 16 to move, and the telescopic rod 16 drives The slide plate 15 moves, and the slide plate 15 drives the blocking cover 8 to move, and the blocking cover 8 drives the second guide block 22 to move along the second guide groove 23 to stop blocking the laser radar scanning device 6 from the environment. At the same time, the blocking cover 7 drives the connecting block 28 to move downward, and the connecting block 28 drives the positioning block 29 to move, so that the positioning block 29 moves to the inner wall of the positioning groove 30, and the positioning block 29 drives the positioning groove 30 to move, and the positioning groove 30 drives the rotating base 5 to move, so that the bottom end of the rotating base 5 abuts against the guide thick rod 26. At this time, the spring 25 undergoes elastic deformation, accumulates elastic potential energy, and stops shaking and buffering. At this time, the buffer disk 24 can be controlled by the control cabin 2 to cooperate with the laser radar scanning device 6 to scan and identify the environment.
