Description

Technical Field

[0001] This invention relates to the field of vehicle cleaning technology, and in particular to a fully automatic cleaning device for vehicles entering and exiting construction sites. Background Technology

[0002] During construction, vehicles are needed to transport building materials. To prevent pollution of the urban environment, vehicles carrying building materials often need to be washed before leaving the construction site. While existing technologies can wash away mud from vehicles, the washed mud remains on the platform and easily adheres to the wheels of other vehicles, increasing the difficulty of vehicle washing and affecting its effectiveness. Chinese utility model patent CN212950524U provides an automatic cleaning device for vehicles entering and exiting construction sites, including a cleaning tank and a water supply mechanism. The cleaning tank contains a mud-removing mechanism, which includes multiple rotating plates. A rotating shaft is fixed inside each rotating plate, and the rotating shaft has a first groove and multiple first through holes connected to the first groove. A second groove is also formed inside each rotating plate, connected to the first through holes. Multiple second through holes are formed at the top of the rotating plate. A gear is fixed to the outer end of the rotating shaft, and a motor is located at the front of the cleaning tank. This technical solution utilizes gears and shafts to drive a rotating plate, allowing the mud on top of the plate to automatically move to the bottom under the influence of gravity and water flow. This prevents the mud from adhering to the wheels of other vehicles, thereby improving the cleaning effect and solving the problem of mud residue affecting vehicle cleaning performance in existing technologies.

[0003] Meanwhile, most existing technologies are only suitable for cleaning vehicles of a single height. However, construction sites have a wide variety of vehicles of different sizes, requiring the construction of different types of vehicle cleaning devices, which is costly and has low utilization. Although traditional manual cleaning can solve the problems of different vehicles, it is labor-intensive and inefficient. In addition, the mud and gravel discharged after cleaning can easily cause sewer blockages. Moreover, construction sites have a lot of mud and dirt, and washing vehicles is wasteful of water resources, which need to be recycled. Therefore, this invention provides a fully automatic vehicle cleaning device for entering and exiting construction sites. Summary of the Invention

[0031] The working principle of the fully automatic vehicle cleaning device for construction sites disclosed in this invention is as follows: The vehicle to be cleaned is driven onto the drain plate 111 via the support plate 104. The height of the limiting plates 201 on both sides is adjusted according to the height of the vehicle to be cleaned. When adjusting the height of the limiting plates 201, the lifting motor 203 is started. The lifting motor 203 drives the connecting shaft 206 to rotate. The connecting shaft 206 drives the two lifting gears 204 to rotate. The rotation of the lifting gears 204 drives the lifting rack 202 to rise or fall on the fixed frame 107, thereby adjusting the height of the limiting plates 201. After the adjustment is completed, the lifting motor 203 is turned off.

[0032] Simultaneously, the transverse motor 301 and the conveyor motor 504 are activated for cleaning operations. The conveyor motor 504 drives one of the conveyor rollers 114 to rotate for conveying. The conveyor roller 114 drives the first pulley 505 on it to rotate. The first pulley 505 on the conveyor roller 114 drives the intermediate pulley 508 on the drain plate 109 to rotate via the second belt 509. The intermediate pulley 508 drives the first pulley 505 on the second rotating shaft 503 and the second rotating shaft 503 to rotate simultaneously via the first belt 506. The second rotating shaft 503 drives... The second gears 502 at both ends rotate simultaneously, driving the first gear 501 to rotate. The first gear 501 drives the impeller 407 located inside the water pump 401 to rotate. The rotation of the impeller 407 transports water from the circulating water tank 101 to the hose 402, and then sprays it out from the nozzle 405 to clean the wheels. At the same time, the transverse motor 301 drives the drive gear 302 to rotate, which in turn drives the transmission gear 306 to rotate. The transmission gear 306 drives the first rotating shaft 304 to rotate. The rotating shaft 304 drives the driven gears 308 at both ends to rotate simultaneously. Since the driven gears 308 and the fixed rack 311 form a gear transmission, the first rotating shaft 304 drives the second slider 309 to slide on the second slide rod 108 through the driven gears 308 and the fixed rack 311. The second slider 309 on the second slide rod 108 drives the third slide rod 310 to move in the length direction of the vehicle. The third slide rod 310 drives the third slider 404 to move in the length direction of the vehicle. While moving, the third slider 404 moves along the limit. The inverted U-shaped track groove on plate 201 moves to achieve a comprehensive cleaning of the wheels. The cleaned sewage flows through the drain plate 111 into the drain conveyor belt 113. The drain conveyor belt 113 performs preliminary filtration of the mud and sand in the sewage. The filtered mud and sand are transported through the drain conveyor belt 113 and discharged from the mud outlet 110. The preliminarily filtered sewage flows into the circulating water tank 101 through the water outlet 115. The sewage is filtered again under the action of the mud baffle 116. The water that has been filtered again is circulated and reused by the water pump 401.
