[0040] A water spraying mechanism is arranged on the water tank 5, and the water spraying mechanism is used for spraying water to remove dust.

[0041] The dust suction mechanism comprises a dust suction unit, a material scraping unit, a material suction unit and a cleaning unit. The material scraping unit comprises a magnetic filter plate 208 fixedly connected to the inner wall of the bottom of the fixed shell 106. A sliding rod 108 is slidably connected to the fixed cover 107. One end of the sliding rod 108 is fixedly connected to a scraper 207. The scraper 207 is in contact with the magnetic filter plate 208. The top end of the sliding rod 108 is fixedly connected to a strip-shaped frame 205. The top of the fixed shell 106 is fixedly connected to an active pipe 105. The inner wall of the active pipe 105 is fixedly connected to a mounting shell 2. A rotating shaft 201 is rotatably connected to the mounting shell 2. One end of the rotating shaft 201 is fixedly connected to a rotating fan blade 202. The rotating fan blade 202 extends into the active pipe 105. The other end of the rotating shaft 201 is fixedly connected to a rotating disc 203. One side of the rotating disc 203 is eccentrically fixedly connected to a cylindrical rod 204. One end of the cylindrical rod 204 extends into the strip-shaped frame 205. Through the arrangement of the material scraping unit, the dust suction unit drives the rotating fan blade 202, the rotating shaft 201, the rotating disc 203 and the cylindrical rod 204 to rotate. The cylindrical rod 204 drives the strip-shaped frame 205, the movable rod 206 and the scraper 207 to move back and forth. The scraper 207 moves to clean the metal parts on the magnetic filter plate 208, thereby avoiding the blockage of the magnetic filter plate 208.

[0042] Further, the two sides of the fixed cover 107 are fixedly connected to collection boxes 209. The two collection boxes 209 are located below the two sides of the magnetic filter plate 208. Through the arrangement of the collection boxes 209, the scraper 207 pushes the metal parts away from the magnetic filter plate 208, and the metal parts fall into the collection boxes 209, thereby realizing the collection of the metal parts by the collection boxes 209.

[0043] Further, the dust suction unit comprises a fan 103 fixedly connected to one side of a collection box 101. The air inlet end of the fan 103 is fixedly connected to a connecting pipe 104. The bottom end of the connecting pipe 104 is slidably connected to the inner wall of the active pipe 105. The air outlet end of the fan 103 is fixedly connected to a fixed pipe 102. One side of the collection box 101 is provided with an air inlet hole. One end of the fixed pipe 102 is fixedly connected to the air inlet hole.

Since the active pipe 105 and the connecting pipe 104 can be combined into an extension rod, they can adapt to uneven ground, so that the fixed cover 107 maintains a suitable interval with the ground, thereby improving the dust suction effect on the ground.

[0044] Further, the suction unit comprises two fixing holes respectively formed in the inner walls of the other two sides of the fixing cover 107, and a rotating rod 3 is rotatably connected in the two fixing holes.

The guide plate 210 is matched with the magnetic fixing rake 303, and both ends of the rotating rod 3 are fixedly connected with rotating wheels 305. Through the setting of the suction unit, the rotating wheels 305 are rotated to drive the rotating rod 3 to rotate, and the rotating rod 3 drives the fixing column 301, the movable column 302 and the magnetic fixing rake 303 to rotate, so that the magnetic fixing rake 303 can adsorb the metal parts and enter the collecting box 209 through the guide plate 210, thereby realizing the collection of larger metal parts. Through the setting of the guide plate 210, the front end of the guide plate 210 is comb-shaped, thereby facilitating the taking of the magnetic fixing rake 303.

[0045] Further, the movable slot is provided with a spring 304, and both ends of the spring 304 are fixedly connected with the fixing column 301 and the movable column 302. Through the setting of the spring 304, when the ground is uneven, the protruding ground can press the magnetic fixing rake 303 to move, so that the magnetic fixing rake 303 presses the movable column 302 to enter the fixing column 301, and at the same time, the spring 304 is compressed, thereby realizing the buffering effect of the magnetic fixing rake 303.

[0046] Further, the cleaning unit comprises a mounting plate 4 fixedly connected to one side of the fixed shell 106, and a fixed shaft 402 rotatably connected to the mounting plate 4. The cylindrical outer wall of the fixed shaft 402 is fixedly connected with an oscillating rake 403, and the top end of the fixed shaft 402 is fixedly connected with a fixed strip 404. The top of the fixed strip 404 is provided with a strip-shaped hole, one side of the movable rod 206 is fixedly connected with an L-shaped rod 405, and one end of the L-shaped rod 405 extends into the strip-shaped hole. Through the setting of the cleaning unit, the movable rod 206 moves to drive the fixed strip 404, the fixed shaft 402 and the oscillating rake 403 to oscillate through the L-shaped rod 405. The oscillating rake 403 oscillates to clean the impurities, thereby realizing the cleaning of the impurities in front of the trolley.

[0047] Further, the two ends of the mounting plate 4 are fixedly connected with inclined plates 401, and the two inclined plates 401 are matched with the oscillating rake 403. Through the setting of the inclined plates 401, the two inclined plates 401 are in the shape of a splay, which can push the impurities to the two sides of the trolley, thereby realizing the effect of not affecting the forward movement of the trolley.

[0048] Further, the bottom end of the fixed shaft 402 is fixedly connected with a connecting arm 406, both ends of the connecting arm 406 are fixedly connected with an arc-shaped plate 407, the arc-shaped plate 407 is matched with the two inclined plates 401, and the outer side wall of the arc-shaped plate 407 is fixedly connected with a plurality of small cylinders 408; through the arrangement of the arc-shaped plate 407, the fixed shaft 402 swings to drive the connecting arm 406 and the arc-shaped plate 407 to swing, the arc-shaped plate 407 swings to drive the small cylinders 408 to swing, the impurities that are not cleaned in time can be cleaned through the swinging of the arc-shaped plate 407, and the cleaning effect of the impurities is improved.

[0049] Further, the water spraying mechanism comprises a water pump 501 arranged on the outer side wall of the water tank 5, the water outlet end of the water pump 501 is fixedly connected with a fixed water pipe 502, the top of the fixed plate 1 is provided with a square groove 503, both sides of the inner wall of the square groove 503 are fixedly connected with a water spraying pipe 504, and the bottom end of the fixed water pipe 502 is fixedly connected with the water inlet end of the water spraying pipe 504; through the arrangement of the water spraying mechanism, the water pump 501 sucks the water in the water tank 5, then the water is introduced into the water spraying pipe 504 through the fixed water pipe 502, and the water is sprayed through the nozzles on the water spraying pipe 504, so that the ground is sprayed and dusted.

[0050] Working principle: when the trolley is pushed to absorb dust and water, the fan 103 is started to suck the dust on the ground through the fixed cover 107 and the fixed shell 106, then through the movable pipe 105 and the connecting pipe 104 into the fan 103, and finally through the fixed pipe 102 into the collection box 101 for collection. In the process of dust absorption, smaller metal parts are absorbed together with dust, and the metal parts are filtered when passing through the magnetic filter plate 208. Because the magnetic filter plate 208 has magnetic force, it can adsorb metal parts. The airflow generated by the fan 103 during dust absorption drives the rotating fan blade 202 to rotate. The rotating fan blade 202 drives the rotating shaft 201 to rotate. The rotating shaft 201 drives the rotating disc 203 to rotate. The rotating disc 203 drives the cylindrical rod 204 to rotate. The cylindrical rod 204 drives the strip frame 205 to move back and forth. The strip frame 205 drives the movable rod 206 and the scraper 207 to move back and forth. The reciprocating movement of the scraper 207 can push the metal parts on the magnetic filter plate 208 away from the magnetic filter plate 208. At this time, the magnetic filter plate 208 will not produce suction force on the metal parts, and the metal parts are above the collection box 209, so that the metal parts fall into the collection box 209 for collection. Because the rotating wheel 305 is in contact with the ground and rotates with the movement of the trolley, the rotating wheel 305 drives the rotating rod 3 to rotate. The rotating rod 3 drives the fixed column 301 to rotate. The fixed column 301 drives the movable column 302 and the magnetic fixed harrow 303 to rotate. The magnetic fixed harrow 303 can adsorb larger metal parts on the ground during rotation. When the magnetic fixed harrow 303 rotates to the position of the guide plate 210, because the front end of the guide plate 210 is a comb structure, it can take down the metal parts adsorbed by the magnetic fixed harrow 303 and enter the collection box 101 through the guide plate 210 for collection. It realizes filtering and collecting smaller metal parts during dust absorption, avoids damaging the fan 103 or causing the filter screen to be blocked, and at the same time picks up and collects larger metal parts, so as to realize recycling of metal parts.

[0051] The movable rod 206 reciprocatingly moves to drive the L-shaped rod 405 to move, the L-shaped rod 405 moves to drive the fixed strip 404 to swing, the fixed strip 404 swings to drive the fixed shaft 402 and the swing rake 403 to swing, the swing rake 403 swings to clean the larger impurities in the forward direction of the trolley, so that the larger impurities are swept to the front of the inclined plate 401, at the same time, the fixed shaft 402 rotates to drive the connecting arm 406 to rotate, the connecting arm 406 rotates to drive the arc-shaped plate 407 and the small cylinder 408 to swing, when the impurities contact the arc-shaped plate 407, the swing arc-shaped plate 407 can push the impurities to the inclined plate 401, with the trolley continuously advancing, the inclined plate 401 can push the impurities away to both sides of the trolley, realizing the cleaning of the impurities in the forward direction of the trolley, avoiding the influence of the impurities on the ground on the trolley advancing, at the same time, the impurities will not collide with the fixed cover 107, thereby not affecting the trolley dust collection and watering.

[0052] The water pump 501 sucks the water in the water tank 5, then guides the water into the water spraying pipe 504 through the fixed water pipe 502, and sprays the water through the spray head on the water spraying pipe 504, realizing the water spraying and dust removal on the ground.

Various modifications to these embodiments will be apparent to those skilled in the art, and the generic principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the application.
