[0015] 1. When the mixing tank needs to be cleaned, the operator uses the cleaning mechanism to spray water from the nozzle assembly. The mixing mechanism drives the nozzle assembly to rotate, so that during the water spraying cleaning process, the nozzle assembly rotates horizontally around the axis of the rotating cylinder and vertically around the center of the third conical tooth.

[0016] 2. When the position of the handrail needs to be adjusted, the present invention first presses the pressure block, which pushes the linkage rod to move and causes the spring to contract. This causes the linkage rod to move the locking block away from the inner wall of the slot, thereby releasing the latch. Then, the handrail is pushed to slide on the inner wall of the slide groove. When it reaches the appropriate position, the pressure block is released, and the spring rebounds, causing the linkage rod to move the locking block back into the inner wall of the slot, thus fixing the handrail again. This allows the height of the handrail to be flexibly adjusted according to the height of different operators and the needs of specific work scenarios, enabling operators to achieve the most comfortable grip height and improving the convenience of operation and work efficiency.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Reference Figures 1-6 As shown, this utility model provides a mobile pneumatic foaming spraying equipment for automotive coating, including a support plate 1, a mixing tank 6 fixedly installed at the top center of the support plate 1, a protective box 7 fixedly installed at the front end of the support plate 1, and columns 31 symmetrically installed at the rear end of the support plate 1. The support plate 1 includes an adjustment mechanism 3 for adjusting the height, a mixing mechanism 4 for mixing, and a cleaning mechanism 5 for cleaning.

[0031] A water pump 51 is fixedly installed at the front end of the top of the mixing tank 6. A water supply pipe 52 is fixedly connected to the outlet of the water pump 51. A rotating cylinder 44 is rotatably connected to the bottom outlet of the water supply pipe 52. The rotating cylinder 44 is rotatably connected to the top wall of the mixing tank 6. A three-way pipe 53 is fixedly connected to the bottom end of the rotating cylinder 44 through the top wall of the mixing tank 6. A nozzle assembly 54 is rotatably connected to both ends of the bottom outlet of the three-way pipe 53. A third conical tooth 55 is fixedly fitted on the outer surface of the nozzle assembly 54. Several baffle rods 57 are fixedly installed on the bottom wall of the mixing tank 6. The top of the several baffle rods 57 is fixedly connected to the same fixed toothed disc 56. The outer surface of the fixed toothed disc 56 meshes with the outer surface of the nozzle assembly 54.

[0032] In this embodiment, when it is necessary to clean the mixing tank 6, the water pump 51 is first started. The water pump 51 draws out water and delivers it to the inside of the rotating drum 44 through the water pipe 52. The water flows into the three-way pipe 53 from the bottom slot of the rotating drum 44, and then flows to the nozzle assembly 54 from the two outlets at the bottom of the three-way pipe 53, so that the nozzle assembly 54 sprays water. Then the motor 41 is started, and its output shaft drives the first conical tooth 42 to rotate. The first conical tooth 42 drives the rotating drum 44 to rotate through the second conical tooth 43, thereby driving the three-way pipe 53 at the bottom and the nozzle assembly 54 to rotate horizontally around the axis of the rotating drum 44. While the nozzle assembly 54 rotates horizontally, it rotates vertically around the center of the rotating third conical tooth 55 when it meshes with the fixed toothed disc 56 through the third conical tooth 55. This allows the water sprayed by the nozzle assembly 54 to clean the inside of the mixing tank 6 from multiple angles, ensuring that the inner wall of the mixing tank 6 is thoroughly cleaned, greatly improving the cleaning efficiency and reducing the workload and time cost of manual cleaning.

[0033] In a further embodiment, the column 31 has a slot 33 and a slide groove 34 inside, the slot 33 and the slide groove 34 are interconnected, and a handrail 32 is slidably connected to the inner wall of the slide groove 34.

[0034] In this embodiment, the slot 33 and the slide groove 34 are connected, so that when the handrail 32 slides to the designated position, it can be locked into the slot 33 by the locking block 39 to fix the handrail 32, so as to meet the position requirements of the handrail 32 under different height requirements.

[0035] In a further embodiment, both ends of the handrail 32 are provided with transmission grooves 35, a pressure block 36 is slidably connected to one side of the handrail 32, a linkage rod 37 is movably connected to one end of the pressure block 36, the middle part of the linkage rod 37 is rotatably connected to the inner wall of the transmission groove 35 by a screw, springs 38 are movably connected to both sides of the linkage rod 37, and a locking block 39 is fixedly connected to one end of the linkage rod 37, the locking block 39 is slidably connected to the inner wall of the locking groove 33.

[0036] In this embodiment, when the position of the handrail 32 needs to be adjusted, the pressure block 36 is first pressed to move it into the transmission groove 35. Simultaneously, the transmission groove 35 moves, pushing the linkage rod 37 to move. Since the linkage rod 37 is fixed inside the transmission groove 35 by a screw, it rotates around the screw under the push of the pressure block 36. During this process, the springs 38 on both sides of the linkage rod 37 are compressed, and the end of the linkage rod 37 away from the pressure block 36 causes the locking block 39 to slide out from the inner wall of the slot 33, thereby releasing the latch. Then, the handrail 32 is pushed... 2. Allow it to slide on the inner wall of the slide groove 34. When the handle 32 reaches the desired position, release the pressure block 36. Under the elastic force of the spring 38, the linkage rod 37 rotates in the opposite direction, driving the locking block 39 to move towards the locking groove 33. When the locking block 39 slides back into the inner wall of the locking groove 33, the handle 32 is fixed on the column 31 again. Thus, the height of the handle 32 can be flexibly adjusted according to the height of different operators and the needs of specific work scenarios, so that the operator can reach the most comfortable grip height, improving the convenience of operation and work efficiency.

[0037] In a further embodiment, a motor 41 is fixedly installed at the rear end of the top of the mixing tank 6. A first conical tooth 42 is fixedly sleeved on the output shaft of the motor 41. A second conical tooth 43 is meshed on the outer surface of the first conical tooth 42. The second conical tooth 43 is fixedly sleeved on the outer surface of the top of the rotating cylinder 44. Several stirring rods 45 are fixedly connected to the lower outer surface of the rotating cylinder 44 extending into the interior of the mixing tank 6.

[0038] In this embodiment, when stirring is required, the motor 41 is started, and its output shaft drives the first conical tooth 42 to rotate. The first conical tooth 42 drives the second conical tooth 43 to rotate. At this time, the rotating cylinder 44 rotates with the rotation of the second conical tooth 43. As the rotating cylinder 44 rotates, the stirring rod 45 also rotates in the stirring tank 6 to stir and mix the materials in the stirring tank 6. Several turbulence rods 57 play a turbulence role during the stirring process, making the materials more turbulent and able to mix together better, ensuring thorough mixing.

[0039] In a further embodiment, a three-way valve 9 is fixedly sleeved at the bottom front end of the mixing tank 6, and a conveying pipe 11 is fixedly sleeved at the right end of the three-way valve 9.

The pressure pump 12 is fixedly installed on the bottom wall of the protective box 7, and a discharge pipe 13 is fixedly sleeved at the outlet of the pressure pump 12. One end of the discharge pipe 13 passes through the top wall of the protective box 7 and extends to the front end of the protective box 7.

[0040] In this embodiment, when a spraying operation is required, the pressure pump 12 is started, and the material flows from the three-way valve 9 at the bottom front of the mixing tank 6 into the conveying pipe 11. The material enters the pressure pump 12 through the conveying pipe 11, and the pressure pump 12 pressurizes the material. The pressurized material flows out from the outlet of the pressure pump 12 and is conveyed to the nozzle of the device through the outlet pipe 13 for foaming spraying operation.

[0041] In a further embodiment, a sewage pipe 10 is fixedly sleeved at the bottom end of the three-way valve 9, and the bottom end of the sewage pipe 10 passes through the inside of the support plate 1 and extends to the bottom of the support plate 1.

[0042] In this embodiment, when it is necessary to discharge sewage or wastewater from the mixing tank 6, the corresponding channel of the three-way valve 9 is opened so that sewage or wastewater can flow out from the sewage pipe 10 through the three-way valve 9. This design allows for easy switching of channels and is simple and convenient to operate.

[0043] In a further embodiment, a feed inlet 8 is provided on one side of the top of the mixing tank 6, and several casters 2 are fixedly installed at the bottom of the bearing plate 1.

[0044] In this embodiment, the feed inlet 8 can put materials into the mixing tank 6, and the casters 2 make the whole equipment mobile, allowing the equipment to move flexibly between different work sites, thus improving the ease of use of the equipment.
