[0038] Preferably, the conveying device comprises a storage tank for storing the cold-sprayed zinc coating and a pump body, the input end of the pump body is connected with the storage tank, and the output end of the pump body is connected with one end of the conveying pipe 19.

[0039] The driving assembly can drive the two lifting assemblies to work simultaneously, and the height of the spray head 20 can be adjusted under the action of the lifting assemblies.

[0040] The cleaning mechanism comprises two main pipes 35, two gas feeding assemblies and a plurality of gas jet heads 36. The two main pipes 35 are symmetrically fixed on the outer sides of the protective cover 12. Specifically, four horizontal plates 37 are symmetrically fixed on the surface of the protective cover 12, and the two ends of each main pipe 35 are fixed on the two horizontal plates 37. The plurality of gas jet heads 36 are installed on the surfaces of the two main pipes 35. Specifically, each gas jet head 36 is inclined to better spray gas onto the surface of the workpiece. The two gas feeding assemblies are symmetrically installed on the protective cover 12, and one end of each gas feeding assembly is connected with one main pipe 35. The two gas feeding assemblies enable the gas to be sprayed out of the gas jet heads 36 to the surface of the workpiece, enabling the gas to be sprayed to the surface of the workpiece to be coated, and enabling the impurities on the surface of the workpiece to be removed, thereby facilitating the improvement of the effect of the subsequent cold-sprayed zinc coating on the surface of the workpiece.

[0041] As shown in Figures 1-6 Each lifting assembly comprises a moving block 16, a light rod 15, a lead screw 14 and two mounting plates 13. The two mounting plates 13 are installed on the inner wall of the protective cover 12. The light rod 15 is rotatably arranged on the two mounting plates 13.

[0043] When the driving assembly works, the light rod 15 can be driven to rotate, and the light rod 15 can drive the lead screw 14 to rotate. Since the guide rail 17 and the guide block 18 are slidably connected, the moving block 16 is guided and limited. Therefore, when the lead screw 14 rotates, the moving block 16 can be lifted, and the conveying pipe 19 and the spray head 20 mounted on the conveying pipe 19 can be moved to adjust the spraying height.

[0044] As shown in Figures 1-6 each rotating assembly comprises a gear 21 and a rack 22, the gear 21 is fixed at one end of the conveying pipe 19, the rack 22 is fixedly installed on the inner wall of the protective cover 12, the gear 21 and the rack 22 are engaged with each other;

[0045] When the conveying pipe 19 moves while driving the gear 21 to move, since the gear 21 and the rack 22 are engaged with each other, when the conveying pipe 19 moves, rotation can be realized through the gear 21 and the rack 22, that is, rotating while moving, thereby realizing the adjustment of the spray angle of the spray head 20.

[0046] It should be noted here that in actual use, the number of teeth on the gear 21 is greater than the number of teeth on the rack 22, when the gear 21 moves a length of the rack 22, the degree of rotation of the gear 21 is less than 180 degrees.

[0047] As shown in Figures 1-6 the driving assembly comprises a motor 26, two driving wheels 23, two driven wheels 24 and two transmission belts 25, the top end of each light rod 15 passes through the protective cover 12 and is fixedly connected with a driven wheel 24, the light rod 15 and the protective cover 12 are rotatably connected;

[0048] The two driving wheels 23 are coaxially arranged and rotatably arranged at the top end of the protective cover 12, each transmission belt 25 is sleeved on a driving wheel 23 and a driven wheel 24, the motor 26 is installed at the top end of the protective cover 12, the output end of the motor 26 is fixedly connected with the two driving wheels 23, specifically, a motor seat is installed at the top end of the protective cover 12, and the motor 26 is fixedly installed on the motor seat.

[0049] When it is needed to move the spray head 20, the motor 26 is controlled to work, the motor 26 can drive the two driving wheels 23 to rotate, and under the action of the two transmission belts 25, the two driven wheels 24 can be driven to rotate, thereby realizing the rotation of the two light rods 15.

[0050] As shown in Figures 1-6 the gas feeding assembly comprises a storage cylinder 27, a gas cylinder 28, a connecting plate 29, a push rod 30 and a push plate 31, the storage cylinder 27 is fixed to one side of the protective cover 12, the storage cylinder 27 is installed on one side of the protective cover 12 through a mounting frame, one end of the storage cylinder 27 is connected with an air outlet pipe 34, the other end of the air outlet pipe 34 is connected with a main pipe 35, thereby realizing the communication between the main pipe 35 and the storage cylinder 27, a gas inlet 32 is installed on the surface of the end of the storage cylinder 27 close to the air outlet pipe 34, the gas inlet 32 facilitates the gas to enter the inside of the storage cylinder 27 for storage;

[0051] The push plate 31 is slidably disposed inside the storage cylinder 27. Specifically, the push rod 30 is a piston plate. The push rod 30 is inserted into one end of the storage cylinder 27 and is slidably connected to the storage cylinder 27. One end of the push rod 30 is fixedly connected to the push plate 31, and the other end of the push rod 30 is connected to the connecting plate 29. The cylinder 28 is fixed to the surface of the protective cover 12 and is located below the storage cylinder 27. The output end of the cylinder 28 is connected to the connecting plate 29.

[0052] In the initial state, the push plate 31 is located inside the storage cylinder 27 and close to one end of the air outlet pipe 34;

[0053] When it is necessary to clean the area of ​​the workpiece to be cold-sprayed with zinc, the cylinder 28 is controlled to work. The cylinder 28 can push the connecting plate 29 to move, and the connecting plate 29 can drive the push plate 31 to move toward the end away from the outlet pipe 34 through the push rod 30. At this time, under the action of negative pressure, the external gas can pass through the air inlet 32 ​​to the interior of the storage tube 27 for storage. Then the cylinder 28 controls the connecting plate 29 to move in the opposite direction, and the connecting plate 29 drives the push plate 31 to move in the opposite direction through the push rod 30, so that the push plate 31 can push the gas out, so that part of the gas can enter the interior of the outlet pipe 34 and be sprayed to the surface of the workpiece through multiple nozzles 36, which can realize the jet treatment of the area to be painted on the surface of the workpiece.

[0054] like Figures 1-6 As shown, a filter screen 33 is installed at the end of each air inlet 32 ​​for filtering. The arrangement of the filter screen 33 allows the gas entering the air inlet 32 ​​to be filtered through the filter screen 33, which is beneficial to reducing the dust content in the gas and preventing the gas ejected by the air nozzle 36 from causing secondary contamination to the surface of the workpiece.

[0055] When the cylinder 28 drives the push rod 30 to move toward the side close to the outlet pipe 34, the gas is squeezed out and part of the gas flows out from the air inlet 32, which can have a recoil effect on the surface of the filter 33 and clean the dust attached to the surface of the filter 33.

[0056] like Figures 1-6 As shown, an exhaust port 38 is provided on the surface of one end of the storage cylinder 27 away from the air outlet pipe 34 . The exhaust port 38 facilitates the inflow and outflow of air, which helps to ensure the balance of the air pressure inside the storage cylinder 27 .
