Cleaning-sweeper-truck suction nozzle structure and cleaning sweeper truck

Abstract

The invention relates to a cleaning-sweeper-truck suction nozzle structure and a cleaning sweeper truck. The cleaning-sweeper-truck suction nozzle structure includes a suction disc, a sucker assembly and a height adjusting mechanism; a suction port for sucking up garbage on the ground is formed in the suction disc, the sucker assembly is communicated with the suction port, the height adjusting mechanism is connected to the sucker assembly and used for adjusting the above-ground height of the sucker assembly, so that the sucking and picking effect of the suction nozzle structure is improved according to different conditions of the garbage on the ground. A transition structure for connecting the suction port with a sucker is integrally trapezoid, and the size of the portion, communicated with the suction port, of the transition structure is no more than three times that of the portion, communicated with the sucker, of the transition structure. By the adoption of the cleaning-sweeper-truck suction nozzle structure, the above-ground height of the sucker assembly can be flexibly adjusted according to distribution conditions of the garbage on the ground, when a lot of fine garbage is distributed on the ground, the above-ground height of the sucker assembly can be appropriately reduced, and strong suction can be provided for the ground; when a lot of large garbage is distributed on the ground, the above-ground height of the sucker assembly can be appropriately increased, so that the large garbage successfully passes through the sucker assembly, and the sucking and picking performance of the cleaning sweeper truck is improved.

Description

technical field [0001] The invention relates to the technical field of sanitation machinery, in particular to a suction nozzle structure of a sweeper and a sweeper. Background technique [0002] During the working process, the sweeper transports the road garbage to the vicinity of the suction nozzle structure through the brush and nozzle. Under the suction of the centrifugal fan, the mixture of mixed garbage and water enters the garbage collection of the sweeper through the suction nozzle structure. In the box, the cleaning process of road rubbish is completed. The structure of the suction nozzle is the key operating part of the sweeper, and its structure directly affects the cleaning efficiency and operation effect of the sweeper. [0003] At present, the suction nozzle structure generally includes a suction port, a suction pipe and a transition structure. The suction pipe and the transition structure are generally arranged perpendicular to the ground, and are high from th...

AI Technical Summary

Problems solved by technology

[0006] The suction pipe and the transition structure of the existing suction nozzle structure are directly welded on the suction nozzle body, and its height above the ground remains constant. The height of the suction pipe and the transition structure cannot be flexibly adjusted according to the size of the ground garbage particles, which affects the suction capacity of the suction nozzle
