[0027] Embodiment 2

[0028] Please refer to Figure 6, the shock absorption mechanism 4 includes a fixed rod 401. On the left and right sides of the outer surface of the fixed rod 401, hinge blocks one 403 are movably arranged. The two hinge blocks one 403 are respectively hinged to one ends of the two connecting rods 406. The ends of the two connecting rods 406 far from the hinge blocks one 403 are respectively hinged to the two hinge blocks two 405. On the left and right ends of the fixed rod 401, fixing plates one 402 are fixed. On the left and right sides and in the middle of the outer surface of the fixed rod 401, second springs 408 are arranged. The two sliding plates 404 are movably arranged in the sliding grooves. The upper surfaces of the two fixing plates one 402 are fixedly connected to the shock absorption plate 1. The two hinge blocks two 405 are fixedly connected to the bottom plate 2. The connecting rods 406 are hinged to the hinge blocks one 403 and the hinge blocks two 405 through positioning pins 407.

[0029] When the shotcrete spraying device moves on an uneven construction site, the universal wheels squeeze the first spring 3 through the bottom plate 2, causing the first spring 3 to contract. The bumpy force is reduced through the first spring 3. When the bottom plate 2 squeezes the first spring 3, it also squeezes the hinge blocks two 405 on the two shock absorption mechanisms 4. Through the connection relationship between the hinge blocks two 405 and the connecting rods 406, the connecting rods 406 are driven to rotate upward at the ends hinged thereto. Through the hinge relationship between the connecting rods 406 and the hinge blocks one 403, the hinge blocks one 403 are pushed to move outward. The sliding plates 404 slide in the sliding grooves, causing the hinge blocks one 403 to move outward through the fixed rod 401. The hinge blocks one 403 squeeze the second springs 408, and the second springs 408 contract under the squeeze. The bumpy force is further alleviated and absorbed through the second springs 408, so that when the shotcrete spraying device moves on an uneven construction site, there will be no bumps and shakes, preventing the components inside the shotcrete spraying device from colliding and being easily damaged. This use effectively solves the problem that when the existing shotcrete spraying device moves, due to the uneven road surface of the construction site, it is easy to generate bumps, causing the components inside the spraying device to be easily damaged by collision.
