The upper end of the frame 1 is equipped with the base 201, the upper end of the base 201 is equipped with the shell 202, and the shell 203 is equipped with the base 201. 02 is installed inside a casing 203, inside the casing 203 is installed a blade 204, one end of the blade 204 is provided with an air inlet 205, one end of the air inlet 205 is provided with an air inlet pipe 206, one end of the air inlet pipe 206 is provided with a telescopic tube 207, the upper end of the telescopic tube 207 is provided with a suction nozzle 208, one end of the blade 204 is provided with a motor 209, one end of the casing 203 is connected with an air outlet pipe 210, one end of the air outlet pipe 210 is provided with a tank cover 211.

[0025] Furthermore, a tank body 212 is installed at the upper end of the base 201, a limiting frame 213 is installed inside the tank body 212, a limiting block 214 is installed at the upper end of the limiting frame 213, a filter bag 215 is installed on the inner side of the limiting block 214, a slide groove 216 is opened inside the tank body 212, a slider 217 is installed inside the slide groove 216, and a dust box 218 is installed on the inner side of the slider 217. 9. The air outlet pipe 210, the tank cover 211, the tank body 212, the limit frame 213, the limit block 214, the filter bag 215, the slide 216, the slider 217 and the dust box 218 are set. The motor 209 rotates the blade 204 to absorb air inside. The air is absorbed through the suction nozzle 208. The air enters the housing 203 through the telescopic tube 207 and the air inlet pipe 206. The suction nozzle 208 can be extended and retracted through the telescopic tube 207. The dust absorbed by the air is collected through the filter bag 215, which is convenient for absorbing air and dust in different areas. The air and dust enter the housing 203 through the air inlet pipe 206, and then are filtered and collected by the filter bag 215, thereby achieving efficient dust collection.

[0026] Furthermore, the blade 204 forms a rotating structure with the housing 203 through the motor 209, and the suction nozzle 208 forms a telescopic structure with the air inlet pipe 206 through the telescopic tube 207. Through the arrangement of the housing 203, the blade 204, the telescopic tube 207, the suction nozzle 208 and the motor 209, the rotating structure formed by the blade 204 and the motor 209 can effectively absorb air and bring it into the body, thereby achieving efficient air circulation and dust collection.

[0027] Furthermore, the shock absorbing mechanism 3 includes a mounting plate 301, a main spring 302, a support rod 303, a support block 304 and a secondary spring 305. The mounting plate 301 is mounted on the upper end of the frame 1, the main spring 302 is mounted on the upper end of the mounting plate 301, the support rod 303 is mounted on the upper end of the main spring 302, the support rod 303 is mounted on the upper end of the support rod 303, and the secondary spring 305 is mounted on the lower end of the support block 304. Through the arrangement of the mounting plate 301, the main spring 302, the support rod 303, the support block 304 and the secondary spring 305, the combination of the spring and the secondary spring 305 can provide a more stable shock absorbing effect. The main spring 302 is used to absorb a large impact force or vibration, while the secondary spring plays an auxiliary role, making the entire shock absorbing system more stable.

[0028] Furthermore, the support rod 303 forms a telescopic structure with the mounting plate 301 through the main spring 302, and the support block 304 forms a telescopic structure with the mounting plate 301 through the auxiliary spring 305. The main spring 302 and the auxiliary spring 305 each form a telescopic structure with the mounting plate 301, which can achieve a graded shock absorption effect. The main spring 302 is usually used to absorb a larger impact or vibration, while the auxiliary spring 305 is used to absorb a smaller impact or vibration, thereby making the shock absorption effect more refined and improving the comfort and stability of the vehicle under different road conditions.

[0029] Working principle: When using this device, the opening part picks up the suction nozzle 208, pulls the suction nozzle 208 to a suitable position through the telescopic tube 207, and then starts the motor 209. The motor 209 drives the blade 204 to rotate, and the blade 204 absorbs air through the suction nozzle 208. The air enters the housing 203 along the air inlet pipe 206 and the telescopic tube 207. The blade 204 rotates inside to accelerate the air, and then enters the tank 212 through the air outlet pipe 210. The filter bag 215 collects the dust in the air, and the dust that is too fine will pass through the filter bag 215 to the dust box 218 Inside, secondary collection is carried out. During transportation, if the terrain is too rugged, the main spring 302 and the auxiliary spring 305 below will reduce the vibration of the collection mechanism 2 to avoid damage to the collection mechanism 2. After a long period of collection, the tank cover 211 is disassembled, and the filter bag 215 is disassembled from the lower frame through the limit block 214, the internal dust is poured out and then installed again, and then the dust box 218 is pulled out from the inside of the tank body 212 through the slide groove 216 and the slider 217, and the internal dust is poured out and then installed again. In this way, the use process of an on-site dust collection device for safety evaluation is completed.
