DETAILED DESCRIPTION

[0030] With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be described clearly and completely. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application.

[0031] With reference to Figures 1-8 The livestock disinfecting and spraying device for animal husbandry and veterinary science comprises a base plate 1, a back frame 2, a tank 3 and a water inlet 4. The back frame 2 is fixedly connected to one side of the top of the base plate 1. The tank 3 is fixedly connected to the middle position of the top of the base plate 1. The water inlet 4 is arranged on the top of the tank 3. The top of the tank 3 is provided with a spraying pump 5. The water outlet end of the spraying pump 5 is provided with a spray pipe 6. One end of the spray pipe 6 is rotatably connected with an atomizing nozzle 8. The atomizing nozzle 8 is fixedly connected with a gear sleeve near the middle of the side close to the spray pipe 6. The gear sleeve is rotatably connected to the outer wall of the spray pipe 6. One side of the spray pipe 6 is fixedly connected with a driving motor 9. The output end of the driving motor 9 is drivingly connected to the gear sleeve. The bottom of the side close to the back frame 2 of the base plate 1 is rotatably connected with an axle 35. The two ends of the axle 35 are fixedly connected with wheels 18. The bottom of the other side of the base plate 1 is fixedly connected with a suspension frame 15. The middle of the suspension frame 15 is fixedly connected with a C-shaped limiting buckle 19. The bottom of the C-shaped limiting buckle 19 is hung with a supporting frame 16. The supporting frame 16 is slidingly connected below the suspension frame 15. Two return springs 17 are symmetrically fixed between the supporting frame 16 and the suspension frame 15. The middle position of the bottom of the suspension frame 15 is fixedly connected with a first travel switch 25. The top of the side away from the tank 3 of the back frame 2 is fixedly connected with two symmetrically arranged control handles 10. The top ends of the two control handles 10 are fixedly connected with handlebars 11. The bottoms of the two handlebars 11 are rotatably connected with gate switches 12. One of the gate switches 12 is connected to the control circuit of the spraying pump 5. The other gate switch 12 is connected to the control circuit of the driving motor 9.

[0032] In use, the disinfectant is injected into the tank 3 through the water injection port 4, and the tank 3 is used to store the disinfectant. When the livestock house is disinfected, the spray pump 5 draws the disinfectant from the tank 3, and the disinfectant is delivered to the atomizing nozzle 8 through the spray pipe 6. The user holds the two control handles 10 with both hands, tilts the back frame 2 away from the tank 3, and only the two wheels 18 support the device on the ground. At this time, the control handle 10 is pushed to control the movement direction of the wheels 18, and the spray pump 5 and the drive motor 9 are controlled by the gate switch 12 on the control handle 10. The worker can control the drive motor 9 to rotate the gear sleeve by one of the gate switches 12 while pushing the control handle 10, so that the atomizing nozzle 8 rotates to realize multi-angle spraying. The other gate switch 12 controls the start and stop of the spray pump 5, which is convenient for the worker to control the atomizing nozzle 8 during the movement of the device. The first travel switch 25 is connected in series to the power supply circuit of the spray pump 5. When the worker stops moving the device and supports the foot support 16 on the ground again, the first travel switch 25 is triggered to disconnect the spray pump 5 from the power supply, forcibly interrupting the spraying to prevent the disinfectant from being sprayed during the parking of the device. When the suspension frame 15 approaches the foot support 16, the compression spring 17 is compressed. When the worker controls the foot support 16 to be away from the ground by tilting the back frame 2 again, the compression spring 17 is reset to push the foot support 16 away from the first travel switch 25, so that the spray pump 5 is connected to the power supply, and the control of the spray pump 5 by the gate switch 12 connected to the spray pump 5 is restored. When the foot support 16 is controlled to be away from the ground, the bottom of the C-shaped limiting buckle 19 serves as the lower limit of the foot support 16 to prevent the foot support 16 from being perpendicular to the ground under the influence of gravity and inertia, thereby avoiding affecting the movement of the device.

[0033] In the present application, the drain end of the spray pump 5 is provided with a water outlet pipe 31, and the same corrugated pipe 7 is connected between the water outlet pipe 31 and the spray pipe 6.

The drive motor 9 is fixed on the side of the spray pipe 6 through the motor bracket 29. Pushing the support frame 30 makes the slide rod 28 slide along the inner wall of the slide rail 24, so as to adjust the position of the atomizing nozzle 8.

[0035] In the application, the sliding rod 28 is made of iron material, both ends inside the slide rail 24 are fixedly connected with permanent magnets, before performing the disinfection operation, the sliding rod 28 is pushed by the supporting frame 30, so that the sliding rod 28 is adsorbed to the permanent magnet close to the atomizing nozzle 8, so as to facilitate the positioning of the atomizing nozzle 8 at the operation position, after stopping the disinfection operation, the sliding rod 28 is pushed in the reverse direction, so that the sliding rod 28 is adsorbed to the permanent magnet close to the back frame 2, so as to facilitate the positioning of the atomizing nozzle 8 in the direction close to the back frame 2, reduce the occupied space of the device, and facilitate storage and storage, the magnetic attraction cooperation of the iron sliding rod and the permanent magnet simplifies the mechanical transmission component, and adapts to the high-frequency use demand in the large-scale breeding scene.

[0037] In the application, the side close to the tank body 3 of the back frame 2 is fixedly connected with equidistantly distributed arc-shaped storage sleeves 13, the outer wall of the tank body 3 is attached to the outer wall of the concave surface of the arc-shaped storage sleeve 13, the inside of the arc-shaped storage sleeve 13 is slidably connected with the closing hoop 14, one end of the closing hoop 14 located outside the arc-shaped storage sleeve 13 is fixedly connected with the same moving link 32, one end close to the moving link 32 of the arc-shaped storage sleeve 13 is fixedly connected with the same fixed link 33, when the tank body 3 is above the chassis 1, all the closing hoops 14 are synchronously pulled by the moving link 32, the closing hoops 14 are pulled out of the arc-shaped storage sleeve 13, until the moving link 32 contacts the fixed link 33, at this time, the closing hoop 14 and the arc-shaped storage sleeve 13 jointly form a ring around the tank body 3, so as to facilitate the fixation of the tank body 3.

[0038] In this invention, a central pin cylinder 20 is fixedly connected to the side of the fixed connecting rod 33 near the moving connecting rod 32, and two end pin cylinders 21 are fixedly connected to the side of the moving connecting rod 32 near the fixed connecting rod 33.

The same positioning pin 22 is inserted into the interior of the central pin cylinder 20 and the two end pin cylinders 21. The central pin cylinder 20 and the two end pin cylinders 21 are locked by the positioning pin 22, thereby fixing the moving connecting rod 32 and the fixed connecting rod 33. When the can body 3 needs to be removed, the positioning pin 22 is pulled out, and the moving connecting rod 32 is pushed away from the fixed connecting rod 33, which drives the closing hoop 14 to be re-inserted into the arc-shaped storage sleeve 13, so that the can body 3 can pass through the circular notch of the arc-shaped storage sleeve 13.

[0039] In this invention, a brake disc 37 coaxial with itself is fixedly connected to the middle of the axle 35. Two suspension columns 38 are symmetrically fixed to the bottom of the chassis 1.
