[0012] Beneficial effects of the utility model:

[0013] The utility model provides a putty spraying machine. In the process of mixing and preparing putty powder, hardened materials will be mixed in the putty powder, which may easily cause the spray gun to be blocked during spraying. In order to ensure smooth spraying, an installation box is arranged on the spray gun assembly. When a staff member puts putty from a feed hopper into a material storage tank, turns on the spray pump, opens the protective cover of the nozzle, presses the spray switch, the nozzle starts to spray putty, and the motor in the installation box is also working at the same time. The rotation of the motor drives the cam to rotate, the cam drives the connecting rod b, the connecting rod a rotates, and the connecting rod b drives the slider to slide on the inner wall of the nozzle. Under the action of the slider, the hardened materials will pass through the nozzle faster, thus avoiding the accumulation of hardened materials in the nozzle, and solving the problem that the putty blocks the spray gun and the spraying operation cannot be continuous.

[0014] The utility model provides a putty spraying machine. In the working environment of the spraying machine, the environment is generally bad. There is a possibility that impurities such as mud, sand and stone enter the spray gun from the nozzle and damage the spray gun structure. Therefore, a protective cover is arranged on the surface of the nozzle of the putty spraying machine. When the putty spraying machine is ready to work, the staff opens the protective cover from the nozzle, starts the putty spraying machine, and putty is sprayed from the nozzle. After the work is finished, the staff covers the nozzle with the protective cover to prevent impurities such as stone and dust from entering the nozzle when the putty spraying machine is not working, so as to avoid damage to the spray gun and affect the completion of the spraying operation.

[0023] Specific examples are given below.

[0024] See also Figure 1-Figure 4 The utility model provides a putty spraying machine, comprising a frame 1, a universal wheel 7 is installed below the frame 1, a storage tank 2 is installed on the frame 1, a feed hopper 3 is installed on the top of the storage tank 2, a spray pump 4 is installed on the outside of the storage tank 2, the storage tank 2 is connected to the spray pump 4, the output end of the spray pump 4 is connected to the nozzle 5, a spray gun assembly 6 is installed on the other side of the nozzle 5, the spray gun assembly 6 includes a nozzle 9, a mounting box 19 is fixed at one end of the nozzle 9, and a motor 13 is installed on the outside of the mounting box 19 A cam 18 is installed on the output shaft of the motor 13, and a slider 14 is movably arranged in the nozzle 9. One end of the slider 14 is rotatably connected to the cam 18 through a connecting rod a16 and a connecting rod b17. The connecting rod a16 and the connecting rod b17 are rotatably connected through a rotating shaft. The cam 18 is rotatably connected to the connecting rod b17, and the slider 14 is rotatably connected to the connecting rod a16. A spray switch 20 is installed on the nozzle 9, and the spray switch 20 is arranged at a paint interface 21, and the paint interface 21 is connected to the nozzle 9.

[0025] During operation, during the mixing and preparation of putty powder, there will be hardened materials mixed in it, which may easily cause the spray gun to be blocked during spraying. In order to ensure smooth spraying, the staff puts the putty into the hopper 3, the putty enters the storage tank 2, turns on the spray pump 4, opens the protective cover 10 of the nozzle 9, uses the nozzle 9 to aim at the wall, presses the spray switch 21, and the nozzle 9 starts to spray putty. At the same time, the motor 13 in the installation box 19 is also working, and the rotation of the motor 13 drives the cam 18 to rotate, and the cam 18 drives the connecting rod b17 and the connecting rod a16 to rotate, and the connecting rod a16 drives the slider 14 to slide on the inner wall of the nozzle 9, so that the putty can be sprayed out through the nozzle 9 more easily, and the possibility of the putty blocking the nozzle 9 is reduced, which solves the problem that the putty blocks the spray gun and cannot be sprayed out.

[0026] Furthermore, two cart handles 8 are provided on one side of the frame 1 , and four universal wheels 7 are installed at the four corners below the frame 1 .

[0027] During work, when there are many walls that need to be sprayed, one worker can use the nozzle 9 to spray the walls, and another worker can use the cart handle 8 to push the putty sprayer to the corresponding area.

[0028] Furthermore, a connecting ring 11 is fixedly mounted on the nozzle 9, and a connecting rod 15 is rotatably connected to the circumferential surface of the connecting ring 11 via a connecting shaft 12.

[0029] During operation, the working environment is generally harsh, and mud, dust, etc. often enter from the nozzle 9. In order to protect the nozzle 9, the protective cover 10 should be opened when preparing for work so that the putty can be sprayed out smoothly. After the work is completed, the protective cover 10 should be covered on the nozzle 9 to prevent stones, dust and other impurities from entering the nozzle 9 when the putty sprayer is not working and damaging the nozzle 9.

[0030] Working principle: During the mixing and preparation of putty powder, there will be hardened materials mixed in it, which may easily cause the spray gun to be blocked during spraying. In order to ensure smooth spraying, the staff puts the putty into the hopper 3, the putty enters the storage tank 2, turns on the spray pump 4, opens the protective cover 10 of the nozzle 9, uses the nozzle 9 to aim at the wall, presses the spray switch 21, and the nozzle 9 starts to spray putty. At the same time, the motor 13 in the installation box 19 is also working. The rotation of the motor 13 drives the cam 18 to rotate, and the cam 18 drives the connecting rod b17, the connecting rod a16 rotates, and the connecting rod b17 drives the slider 14 to slide on the inner wall of the nozzle 9, so that the putty can pass through the nozzle 9 more easily. Spraying reduces the possibility of putty blocking the nozzle 9, and solves the problem of putty blocking the spray gun and not being able to spray out. When there are many walls that need to be sprayed, one staff member can use the nozzle 9 to spray the wall, and another staff member uses the cart handle 8 to push the putty sprayer to the corresponding area. The general working environment is relatively harsh, and mud, dust, etc. often enter from the nozzle 9. In order to cooperate with the protection of the nozzle 9, when preparing for work, the protective cover 10 should be opened to allow the putty to be sprayed smoothly. After the work is completed, the protective cover 10 is covered on the nozzle 9 to prevent stones, dust and other impurities from entering the nozzle 9 when the putty sprayer is not working, and damaging the nozzle 9.
