[0035] As shown in the drawings, Figure 4 , 5As shown, in the embodiment, the dust removal assembly 4 comprises a cylinder, a dust collection box 43 and an exhaust pipe 44. The cylinder comprises a cylindrical cylinder 41 and a conical cylinder 42. The cylindrical cylinder 41 is installed on the conical cylinder 42. The dust collection box 43 is detachably installed at the bottom outlet of the conical cylinder 42. An air inlet 410 is arranged on the side wall of the cylindrical cylinder 41. The air inlet 410 is connected with the containing cavity 10 through a pipeline. The exhaust pipe 44 is arranged at the top of the cylindrical cylinder 41 and extends axially into the cylinder. An outlet end of the exhaust pipe 44 is provided with a suction device 45. A discharge outlet 450 is arranged on the side wall of the suction device 45. The discharge outlet 450 is connected with the containing cavity 10 through a pipeline. The suction device 45 is used to circulate the air in the containing cavity 10 and the cylinder. The cylinder, the dust collection box 43, the exhaust pipe 44 and the suction device 45 work cooperatively to realize the circulation filtration of the air in the containing cavity 10, remove dust and impurities and provide a clean environment for the coating process. The suction device 45 is the power source of the entire dust removal assembly 4. After the suction device 45 is started, a strong suction force is generated at the outlet end of the exhaust pipe 44. Due to the action of the suction device 45, a negative pressure is formed in the exhaust pipe 44, and the inside of the cylindrical cylinder 41 is also in a relatively negative pressure state. The dust-containing air in the containing cavity 10 is sucked into the cylindrical cylinder 41 through the pipeline connected with the air inlet 410 under the action of the pressure difference. After the dust-containing air enters the cylindrical cylinder 41, the flow velocity is reduced due to the sudden increase in space. Some large particles of dust begin to settle on the cylinder wall and the bottom under the action of inertia. With the continuous flow of dust-containing air, the dust-containing air enters the conical cylinder 42. The conical cylinder 42 has the structural feature that it is large at the top and small at the bottom. The flow velocity of the dust-containing air gradually slows down during the downward flow. The dust is more likely to gather at the bottom under the action of gravity. Most of the remaining dust and impurities move to the bottom of the conical cylinder 42 during this process and finally fall into the dust collection box 43. The relatively clean air after the dust separation in the cylinder enters the exhaust pipe 44. The suction device 45 sucks the clean air out of the exhaust pipe 44 and sends it back to the containing cavity 10 through the discharge outlet 450 on the side wall of the suction device 45 through the pipeline, thereby realizing the circulation of the air in the containing cavity 10 and the cylinder and achieving the purpose of continuously keeping the air in the containing cavity 10 clean. The detachable design of the dust collection box 43 facilitates the regular cleaning of the dust collection box 43 and ensures the continuous and effective work of the dust removal assembly 4. The dust collection box 43 is in sealed connection with the conical cylinder 42 through a flange.

[0036] In the embodiment, the suction device 45 comprises a shell 451 which is a hollow cylindrical structure and is connected to the outlet end of the exhaust pipe 44; an impeller 452 which is arranged inside the shell 451 and is used to generate negative pressure to suck air flow; and a driving motor 453 which is installed outside the shell 451 and has an output end connected to the impeller 452. The impeller 452 rotates at high speed under the drive of the driving motor 453, and a negative pressure area is formed around the impeller 452 by Bernoulli's principle, thereby generating strong suction force to suck the air flow at the outlet end of the exhaust pipe 44 into the shell 451, so as to realize the directional flow of air from the cylinder to the exhaust port 450 and ensure the power source for air circulation between the accommodating cavity 10 and the cylinder. The driving motor 453 is designed to be external, so that the maintenance, repair and troubleshooting of the motor are more convenient.

[0037] In the embodiment, the box body 1 is provided with a set of adjustable supports 7, and the adjustable supports 7 are circumferentially spaced apart along the box body 1. Different work sites may have uneven ground, and the height of the box body 1 can be finely adjusted through the adjustable supports 7 to make the box body 1 in a horizontal state, so as to ensure the stability of the equipment and avoid the adverse effects of equipment shaking caused by uneven ground on the coating process. The number of the set of adjustable supports 7 is four.
