Embodiment Construction

[0039] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0040] In the present invention, unless stated otherwise, the orientation words used such as "up, down, bottom, top, front, back" are usually relative to the state of the road sweeper when it is working normally, specifically , the forward direction of the road sweeper is "front", and the backward direction of the road sweeper is "rear". In addition, "inside and outside" refer to the inside and outside of the corresponding component contour.

[0041] like Figure 1 to Figure 6 As shown, according to one aspect of the present invention, a kind of suction nozzle for road sweeping vehicle is provided, and this suction nozzle for road sweeping vehicle comprises fro...

Abstract

The invention discloses a suction nozzle used for a sweeper truck and the sweeper truck. The suction nozzle used for the sweeper truck comprises a front baffle, a hoarding plate, a top plate and a suction pipe, the front baffle, the hoarding plate and the top plate define a suction nozzle cavity with an opening formed at the lower end, a connecting hole is formed in the top plate, the suction pipe is installed on the top plate through the connecting hole and communicated with the suction nozzle cavity, a channel used for large-size garbage to enter therein is formed in the front baffle, and the suction nozzle used for the sweeper truck is further provided with a self-adaption adjusting mechanism used for blocking or opening the channel. Therefore, the channel special for the large-size garbage on the road surface to enter therein is formed in the front baffle, meanwhile, the self-adaption adjusting mechanism used for blocking or opening the channel is arranged, therefore, the suction nozzle cavity can be designed into a small cavity, so that the suctioning and lifting capacity is promoted, when the large-scale garbage exists on the road surface, the channel is opened automatically, and when the large-scale garbage is suctioned, the channel is automatically restored to a normal inlet of great suctioning and lifting capacity.

Description

technical field [0001] The invention relates to the field of road cleaning equipment, in particular to a suction nozzle for a road sweeper and a road sweeper using the suction nozzle for a road sweeper. Background technique [0002] The suction nozzle for road sweeper is a key component that affects the performance of the road sweeper. Under the same flow conditions, the design of the nozzle directly determines the cleaning rate of the road sweeper. Under the premise of ensuring sufficient cleaning performance, the suction The flow rate required by the suction nozzle with superior performance is much lower than that of the conventional solution, and when the flow rate of the fan is reduced, its noise and energy consumption are reduced accordingly. [0003] In order to improve the suction performance of the suction nozzle, it is generally necessary to design the cross-sectional area of ​​the airflow channel of the suction nozzle to be small to increase the airflow velocity, s...
