[0032] The specific arrangement and function of the shock absorbing device 5 and the fixing device 6 will be described in detail below.

[0033] like Figure 1 and Figure 2 as well as Figure 3As shown, the shock absorbing device 5 includes four first sleeves 501, and the four first sleeves 501 are all sleeved on the surface of the support rod 2. The first connection disk 502 is fixedly connected to the side of the four first sleeves 501 away from the support rod 2, and the damper 504 is fixedly connected to the side of the first connection disk 502 away from the first sleeve 501, and the other end of the damper 504 is fixedly connected to the second connection disk 503. By setting the first sleeve 501 and the first connection disk 502, the damper 504 can be connected to the support rod 2, and by setting the damper 504, a shock absorbing effect can be achieved. Four sliding rods 506 are fixedly connected to the side of the second connection disk 503 close to the damper 504, and the four sliding rods 506 are all slidably connected to the inner wall of the first connection disk 502, and the ends of the four sliding rods 506 away from the second connection disk 503 are fixedly connected to the limiting block 507.

The surface of the damper 504 is covered with a spring 505, and the two ends of the spring 505 are respectively fixedly connected to the first connection plate 502 and the second connection plate 503. By providing the spring 505, the effect of auxiliary shock absorption can be achieved, and the stability of the connection between the first connection plate 502 and the second connection plate 503 can be improved.

[0034] A fixed block 508 is fixedly connected to the side of the second connection disk 503, and a moving block 509 is fixedly connected to the side of the first connection disk 502. By setting the fixed block 508, the position of the second connection disk 503 can be restricted, and by setting the moving block 509, the first connection disk 502 can be installed while ensuring that the first connection disk 502 can move. A connecting plate 511 is fixedly connected to the end of the fixed block 508 away from the second connection disk 503, and two sliding grooves are provided on the side of the connecting plate 511 close to the moving block 509. The surfaces of the sliding grooves on the two connecting plates 511 are slidably connected with sliders 510, and the sliders 510 are fixedly connected to the moving block 509. A second sleeve 512 is fixedly connected to the side of the connecting plate 511 away from the support rod 2, and the second sleeve 512 is sleeved on the surface of the axle 3. By providing the second sleeve 512 , the axle 3 can be connected to the connecting plate 511 , thereby completing the connection between the axle 3 and the support rod 2 . By providing the slider 510 , a stable connection between the moving plate and the connecting plate 511 can be ensured.

[0035] like Figure 2 and Figure 4 as well as Figure 5As shown, the fixing device 6 includes four "L"-shaped plates 61, and the four "L"-shaped plates 61 are fixedly connected to the surface of the support rod 2. The four "L"-shaped plates 61 are fixedly connected to the side away from the support rod 2 with a connecting block 62, and the side of the second connecting plate 503 is fixedly connected with a fixing plate 63, and the inner walls of the connecting block 62 and the fixing plate 63 are threadedly inserted with a first screw 64. By setting the "L"-shaped plate 61 and the connecting block 62 and the fixing plate 63 and the first screw 64, the second connecting plate 503 can be fixedly connected to the support rod 2.

[0036] Two second curved plates 66 are fixedly connected to the surface of the axle 3, and two first curved plates 65 are fixedly connected to the surface of the second sleeve 512.

[0037] Working principle: when it is necessary to spray the liquid medicine, first place the liquid medicine on the frame 1, then control the wheel 4 to rotate so that the frame 1 drives the liquid medicine to move. When the road surface is bumpy, the frame 1 drives the support rod 2, the first sleeve 501 and the first connecting plate 502 to move close to the second connecting plate 503. At this time, the moving block 509 drives the slider 510 to slide on the surface of the slide groove on the connecting plate 511. Under the action of the damper 504 and the spring 505, the speed of the first connecting plate 502 approaching the second connecting plate 503 is slowed down, which has a shock absorbing effect. At the same time, the slide bar 506 slides on the inner wall of the first connecting plate 502 to ensure the stable operation of the spring 505 and the damper 504 as much as possible. Then, under the action of the spring 505 and the damper 504, the first connecting plate 5 02 moves away from the second connecting disk 503 to complete the shock absorption process. By setting the limit block 507, the stable connection between the slide bar 506 and the first connecting disk 502 can be guaranteed. By setting the fixing block 508 and the connecting plate 511, the position of the second connecting disk 503 can be fixed. By setting the first sleeve 501 and the second sleeve 512, the support rod 2 and the axle 3 can be connected. When producing the shock absorbing device 5, the cast steel one-piece molding technology is used for the production of parts, which can improve the efficiency of parts production. By setting the shock absorbing device 5, when the sprayer is used to spray the liquid medicine, the sprayer can be shock-absorbing. The impact of the bumps on the spraying of the sprayer during the movement of the sprayer is reduced, thereby ensuring the uniformity of the liquid medicine spraying as much as possible.

[0038] When installing the shock absorbing device 5, first move the first sleeve 501 and the second sleeve 512 close to the support rod 2 and the axle 3 respectively, then rotate the first screw 64 to connect the connecting block 62 and the fixing plate 63, so as to ensure the stability of the connection between the first sleeve 501 and the support rod 2 as much as possible, and then rotate the second screw 67 to connect the first arc plate 65 and the second arc plate 66, so as to ensure the stability of the connection between the second sleeve 512 and the axle 3 as much as possible. By setting the "L"-shaped plate 61, the connecting block 62 can be connected to the support rod 2. By setting the fixing device 6, when installing the shock absorbing device 5, the stability of the installation of the shock absorbing device 5 can be ensured as much as possible, and the separation of the support rod 2 or the axle 3 from the shock absorbing device 5 can be avoided as much as possible, and the wheel 4 and the frame 1 will not be separated during the movement of the sprayer.
