Suction nozzles and road cleaning vehicles

Abstract

The invention discloses a suction nozzle, including a suction nozzle body (210) and a rotating air door, wherein the suction nozzle body includes a suction hole (220); the rotating air door is positioned in front of the suction hole; the rotating air door includes a rotating shaft (251), a plurality of shifting plates (252) and a shell (254); the shell is connected with the suction nozzle body; the rotating shaft passes through the shell and is rotationally arranged with respect to the shell; the plurality of shifting plates are distributed at intervals along the circumferential direction of the rotating shaft; the shell partly covers the rotating shaft and the shifting plates and limits an air door suction hole (255) along the periphery of the rotating shaft. The invention also provides a road cleaning truck including the suction nozzle. Negative pressure can be generated at the air door suction hole by a suction device, so that the shifting plates rotate to stir large garbage at the front end of the air door suction hole so as to be convenient to collect. During the rotating plate of the shifting plates, the shifting plates moving to the range of the shell can forma a good sealed space with the shell, thus being conductive to maintain the negative pressure at the air door suction hole, and allowing the shifting plates to rotate continuously.

Description

Technical field [0001] The present invention relates to the field of environmental sanitation, and in particular, to a suction nozzle and a road cleaning vehicle including the suction nozzle. Background technique [0002] The suction nozzle is the main garbage collection device on road cleaning vehicles such as road sweepers and sweepers. The suction nozzle usually includes a nozzle body and a flexible baffle. The nozzle body includes a suction port. The flexible baffle is arranged in front of the nozzle body. The other direction of the nozzle body is a rigid baffle. When the suction nozzle is working, the vehicle moves forward, and the inside of the suction nozzle is under negative pressure. The baffle will turn back and up when affected. The garbage in front of the suction nozzle enters the suction port through the baffle, and finally enters the garbage bin through the suction pipe connected with the suction port. . [0003] The flexible baffle will wear out after a period of u...

AI Technical Summary

Problems solved by technology

If the baffle is too soft, the garbage can easily enter the suction nozzle, but the opening of the suction nozzle will increase and the suction will decrease significantly; if the baffle is too hard, the baffle will not be easily deformed, and the garbage will be easily blocked by the baffle outside the suction nozzle

In addition, because the baffle has to take into account the dual functions of sealing and feeding (this is a contradictory requirement), when cleaning up large garbage such as mineral water bottles and lunch boxes, the baffle can basically only block it from the suction nozzle. cannot be collected effectively
