Description

Technical Field

[0001] The present invention relates to the technical field of road surface cleaning, and particularly to a multi-functional and efficient leaf sweeper. Background Art

[0002] The cleaning of road surface leaves is an important link in urban environmental sanitation management, especially critical in autumn when the amount of fallen leaves increases significantly. Effective leaf cleaning can not only keep the streets clean and beautiful, but also prevent drainage system blockages, reduce the risk of traffic accidents, and improve the overall environmental quality of the city.

[0003] The patent with the patent application number CN202110533031.3 records in its specification that "The present invention discloses a mechanical automatic sweeper, which includes a sweeper, a vehicle body, and a handrail. Since the surfaces of the leaves are wet after rainfall, multiple leaves stick together in a cluster. When the clustered leaves pass through the suction cup, they are easily stuck in the feed pipe of the suction cup. By providing a dispersion mechanism at the top inside the suction cup, the push rod and the matching rod are movably matched to impact, disperse, and crush the clustered leaves, which can reduce the leaves being stuck in the feed pipe of the suction cup and further accelerate the leaf cleaning speed of the sweeper. When the ground is muddy, some mud blocks adhere to the outer walls of the leaves. The leaves are attracted by the air pump and stick to the outer walls, resulting in the mud blocks on the outer walls of the leaves adhering to the outer wall of the air pump and gradually solidifying, causing the suction force of the air pump to decrease. By providing a push plate outside the bottom end of the pump body, the pump body is protected by the push plate, which can reduce the leaves being directly attracted to the outer wall of the pump body by the suction force, increase the suction force of the air pump, and accelerate the speed of leaf absorption." However, in the above technology, the following disadvantages will occur during use: Although the above technology can reduce the leaves being stuck in the feed pipe of the suction cup through the dispersion mechanism and further accelerate the working efficiency of the sweeper, the air pump will also inhale ground dust during operation. The inhaled dust needs to be discharged from the exhaust port of the air pump, and the discharged dust will fill the air near the sweeper, which is not conducive to environmental protection and also affects the health of the operators. Therefore, there is an urgent need for a multi-functional and efficient leaf sweeper to solve the above problems. Summary of the Invention

The staff controls the first motor 9, the second motor 703, the third motor 706, the suction fan 713, and the fourth motor 711 to work respectively through the control panel 3. When the suction fan 713 works, it sucks away the air in the cyclone separator 712, the discharge pipe 710, and the guide pipe 708, forming a negative pressure phenomenon, which causes the guide pipe 708 to suck in a large amount of air quickly from the feed inlet 719. The suction fan 713 discharges the air into the air guide box 715 through the connecting pipe 714. When the air in the air guide box 715 is discharged from the air outlet 728, it is guided by the air guide plate 727 towards the enclosure 701 and the rubber sheet 702, so that the discharged air returns to the vicinity of the feed inlet 719, forming an air duct circulation, which is beneficial to reducing the influence range of the discharged air and avoiding the situation of a large amount of dust polluting the environment and affecting the health of the operators.

When the first wheel frame 5 rotates, it drives the second brush roller 6 to rotate, and cooperates with the first brush roller 8 to sweep the leaves on the ground towards the feed inlet 719. The rubber sheet 702 contacts the ground to facilitate blocking the swept leaves, so that the leaves can stay below the feed inlet 719, and the leaves are sucked into the guide pipe 708 by the flowing air at the feed inlet 719. When the third motor 706 on the fixing frame 705 works, it drives the second transmission structure 721 to work. The second transmission structure 721 includes a first synchronous pulley, a second synchronous pulley, and a synchronous belt.

The rotating rod 722 rotates within the mounting frame 720, and the mounting frame 720 is fixed within the guide pipe 708, which is convenient for enhancing the stability of the mounting frame 720 and the crushing blades 723. When the crushing blades 723 rotate, they crush the leaves entering the guide pipe 708. After the crushed leaves enter the cyclone separator 712 through the guide pipe 708, they are separated. Cooperating with the guiding plate 717, it is convenient to guide the shredded leaves into the discharge pipe 710. The setting of the post-stage filter 716 is convenient for filtering dust and debris in the air. When the fourth motor 711 works, it drives the spiral conveying roller 718 to rotate within the discharge pipe 710. When the spiral conveying roller 718 rotates, it pushes the shredded leaves in the discharge pipe 710 towards the pressing plate 725. Affected by the negative pressure in the discharge pipe 710, the pressing plate 725 is pushed by the external air pressure to closely adhere to the outer surface of the discharge pipe 710, and the spiral conveying roller 718 continuously pushes the shredded leaves to achieve the effect of squeezing the shredded leaves, which is beneficial to reducing the volume of the shredded leaves.When the operator flips the pressing plate 725, it drives the connecting rod 726 to rotate, and at the same time drives the elastic member 7 fixed on the vertical plate 724 to deform. Subsequently, the mouth of the garbage bag is sleeved on one end of the discharge pipe 710. After releasing the pressing plate 725, the pressing plate 725 clamps and fixes the garbage bag at one end of the discharge pipe 710. When the force of the spiral conveyor roller 718 pushing the shredded leaves is greater than the external air pressure acting on the pressing plate 725, the compressed shredded leaves are pushed out of the material pipe 710 by the spiral conveyor roller 718 into the garbage bag, which is beneficial to collecting the shredded leaves, reducing the labor intensity of the operator for subsequent cleaning of the shredded leaves, and improving the working efficiency of cleaning the leaves on the road surface.
