Description

Technical Field

[0001] The invention relates to the technical field of road maintenance, in particular to a device for cleaning fallen leaves on municipal road greening. Background Art

[0002] Cleaning fallen leaves from municipal road greening is crucial to maintaining the urban environment, but traditional manual cleaning is inefficient, labor-intensive, and poses safety risks. Early mechanical cleaning devices used a roller brush combined with an onboard collection box. While this improved cleaning efficiency, it was ineffective for cleaning scattered fallen leaves, especially around green belts and in the cracks of curbstones. The roller brushes also tended to become entangled in fallen leaves, requiring frequent cleaning stops. With increasing environmental protection requirements, traditional cleaning systems are prone to generating dust, failing to meet green operation standards.

The device comprises a movable box, a collection pipe, an exhaust fan, and a cleaning assembly. The collection pipe communicates with the inner cavity of the movable box through a collection hole provided in the movable box, and the exhaust fan communicates with the inner cavity of the movable box through an air outlet provided in the movable box. The cleaning assembly comprises a cleaning plate, a first sliding rod, a door panel, a second sliding rod, an adjustment rod, and a connecting rod. The cleaning plate is disposed in the inner cavity of the movable box. The first sliding rod engages with the sliding hole provided in the movable box. One end of the first sliding rod is connected to the cleaning plate. The door panel engages with a door opening provided in the movable box. The door panel slides up and down along the movable box.

The rotation of the reciprocating screw 4 will drive the L-plate 9 to rotate. However, at this time, the L-plate 9 is limited by the limit column. The limit column will cause the L-plate 9 to be able to move back and forth laterally only through the reciprocating groove on the surface of the reciprocating screw 4 when the reciprocating screw 4 rotates. During the reciprocating lateral movement of the L-plate 9, the L-plate 9 will drive the collection pipe 10 to move. During the reciprocating movement of the collection pipe 10, the fan 7 will start, and the fan 7 will suck the fallen leaves on the road surface into the inside of the collection box 2 through the collection pipe 10. At this time, the reciprocating movement of the collection pipe 10 can expand the coverage of the cleaning and suction, avoid missing sweeping, adapt to the irregular boundaries of the road, and increase the suction and collection speed of the fallen leaves.

When the device is started, the electric telescopic rod 502 will start, and the telescopic end of the electric telescopic rod 502 will drive the fixed block 503 to move downward. During the movement of the fixed block 503, the fixed block 503 will drive the hinge plate 1 504 to move downward. During the downward movement of the hinge plate 1 504, the hinge plate 1 504 will open the opening at the bottom of the connection box 8 and realize its own angle rotation through the torsion spring during the movement. At the same time, the movement of the hinge plate 1 504 will drive the pull rod 2 505 to move. The pull rod 2 505 will move downward. During the process, the sliding column 2 506 will be synchronously driven to move, and the movement of the sliding column 2 506 will drive the moving plate 507 to move. During the movement of the moving plate 507, the moving plate 507 will push the fallen leaves accumulated inside the connection box 8 and push them into the interior of the collection box 2 through the opening opened by the hinged plate 1 504 for collection. This can prevent the fallen leaves from accumulating inside the connection box 8 and affecting the air circulation, resulting in a decrease in the air extraction efficiency of the fan 7, thereby reducing the suction and cleaning efficiency of the fallen leaves, and can improve the fallen leaf suction speed of the device; The exhaust mechanism 5 also includes an exhaust shell 508, a second hinged plate 509, an air storage column 510, an air nozzle 511, and an air pipe 512. The exhaust shell 508 is fixedly connected to the top of the collection box 2. The second hinged plate 509 is rotatably connected to the inner wall of the exhaust shell 508 by a torsion spring.

When the device is started, there is rain on the road, and the speed of collecting fallen leaves will be reduced. The fan 7 will increase the suction force. At this time, the exhaust speed of the fan 7 will be accelerated during the process of exhausting air. The air exhausted by the fan 7 will push the hinge plate 2 509 to rotate at an angle. During the rotation of the hinge plate 2 509, the hinge plate 2 509 will release the seal of the connection between the exhaust shell 508 and the air pipe 512. At this time, a part of the air exhausted by the fan 7 will enter the interior of the air storage column 510 through the air pipe 512. At the same time, during the movement of the sliding column 16, the sliding column 16 will drive the air storage column 510 to move back and forth, and the movement of the air storage column 510 will drive the nozzle 511 to move. At this time, the nozzle 511 can spray the air inside the air storage column 510. The sprayed air will be guided by the inclined surface of the inclined scraper 17 and sprayed to the bottom of the fallen leaves, which can make the fallen leaves move a short distance, avoid the fallen leaves staying for a long time and having a large adhesion to the road surface, and can improve the efficiency of sucking and cleaning the fallen leaves, thereby improving the use effect of the device; The pushing mechanism 6 includes an L-block 601, a fixed column 602, and a push plate 603.

The movement of the L block 601 drives the fixed column 602 to move, and the movement of the fixed column 602 drives the push plate 603 to move. During the movement of the push plate 603, the push plate 603 can push and scrape the broken fallen leaves remaining on the surface of the filter plate 501, thereby ensuring the air suction force of the fan 7, increasing the speed of the fallen leaf suction and cleaning, and improving the service life of the device.

At this time, the fallen leaves collected inside the collection box 2 need to be moved out. The operator can manually rotate the rotary lock plate 608 and pull the pull column 606 outward, so that the limit of the rotary lock plate 608 on the pull column 606 can be released. At this time, the elastic telescopic rod 2 604 will slowly reset and drive the transverse plate 605 to move. During the movement of the transverse plate 605, the transverse plate 605 can push the fallen leaves to the opening and closing door 607.

[0016] The overall working principle: the movable plate 507 will push the fallen leaves accumulated inside the connecting box 8 and push them into the collecting box 2 through the opening opened by the hinged plate 504 for collection, which can prevent the fallen leaves from accumulating inside the connecting box 8 and affecting the air circulation, resulting in a decrease in the air extraction efficiency of the fan 7, thereby reducing the efficiency of sucking and cleaning the fallen leaves, and can improve the fallen leaf suction speed of the device. The nozzle 511 can spray the air inside the air storage column 510, and the sprayed air will be guided by the inclined surface of the inclined scraper 17 and sprayed to the bottom of the fallen leaves, which can make the fallen leaves move a short distance, avoid the fallen leaves staying for a long time and having a large adhesion to the road surface, and can improve the efficiency of sucking and cleaning the fallen leaves.
