Description

Technical Field

[0001] The present invention relates to the technical field of sweeper equipment, in particular to a sweeper which is convenient for separating and discharging sewage. Background Art

[0002] As an important component of the urban environmental maintenance and industrial cleaning system, the operating efficiency of sweepers is directly related to the management quality and operating cost control of urban public spaces. Faced with new environmental challenges such as microplastic pollution and composite material packaging, traditional operating models present multiple constraints when dealing with mixed garbage: it is difficult to accurately distinguish between waste types with similar shapes during the processing process, resulting in reduced efficiency in the subsequent disposal process; the sewage discharge function is not well matched with the operating intensity, which can easily cause intermittent equipment stagnation; and the misjudgment of recyclable resources during the sorting stage exacerbates resource loss and disposal costs. The current operating system has systemic deficiencies in important links such as adapting to the dynamic changes in garbage composition and connecting classified disposal with resource utilization. This functional connection fault not only affects the response speed of cleaning services, but also forms a continuous practical obstacle to the construction of a new urban management model with coordinated development of environmental governance and resource recycling.

[0003] Traditional sweepers can only collect floating debris on the ground. When sweeping the ground directly, it is easy to cause a lot of dust to fly. Moreover, it is impossible to collect debris adhering to the ground. At the same time, it is impossible to separate debris and water when sweeping and collecting wet ground. Therefore, a sweeper that is easy to separate and discharge sewage is invented to address the above defects. Summary of the Invention

[0043] (1) When the machine starts working, the motor 308 and the suction fan 502 are started at the same time, and the handle 1 is pushed at the same time. The handle 1 pushes the device to move as a whole. The motor 308 drives the first connecting shaft 311 to move through the turntable 310. The first connecting shaft 311 drives the vertical rod 305 to move back and forth through the first connecting rod 306. The vertical rod 305 presses the water in the water tank 301 into the rotating box 318 through the piston plate 304, and sprays it onto the ground through the nozzle 313. The movement of the first connecting rod 306 drives the pressure rod 321 to move up and down. When the pressure rod 321 moves up and down, it drives the rotating box 318 to rotate around the second connecting shaft 314, thereby driving the nozzle 313 to swing, and then realizing multi-angle water spraying on the ground.

[0044] (2) When the first connecting rod 306 is raised or lowered, it drives the transmission rod 404 to rise or fall. The transmission rod 404 drives the connecting shaft 411 to move through the second connecting rod 405. The connecting shaft 411 drives the third connecting shaft 413 to move along the folding groove 412 through the scraper frame 409, thereby driving the scraper 403 to move. The scraper 403 scrapes away debris on the ground, and the scraped debris is collected by the folding rod 402.

[0045] (III) The scraped debris is sent into the collection tank 501 by the suction fan 502, and then the debris is separated from the water under the action of the mesh plate 513. When the cleaning is completed, the handle 1 is stopped and the motor 308 stops working. Then the first electric cylinder 512 is started, and the first electric cylinder 512 drives the lifting rod 503 to rise. The lifting rod 503 pushes the fixed half ring 505 to move through the third connecting rod 504. Under the action of the fixed half ring 505, the second transmission shaft 508 slides along the installation groove 510. When the suction fan is turned on, the second transmission shaft 508 slides along the installation groove 510. When 502 is out of contact with the collection tank 501, the gear 507 is engaged with the rack 516. Under the action of the rack 516, the collection tank 501 starts to rotate. When the collection tank 501 contacts the discharge chute 205, the first electric cylinder 512 stops working. At this time, under the action of gravity, the water is discharged through the collection tank 501. When the water is completely discharged, the second electric cylinder 515 is started. The second electric cylinder 515 pushes the debris on the mesh plate 513 out of the collection tank 501 through the mesh plate 513, thereby completing the separation of the debris and water.
