Description

Road sweeper suction tube structure

(I) technical field

The utility model relates to a suction pipe structure of a road sweeper.

(II) background of the utility model

With the increasing demand of the sanitation industry for the dry-wet cleaning equipment, the number of the dry cleaning equipment is also increasing.

Most of dry-type cleaning equipment is provided with a back-blowing pipeline structure, the existing pipeline design of a suction pipeline and a back-blowing pipeline adopts a design form that the suction pipeline and the back-blowing pipeline are arranged side by side, the pipeline design of the form has higher requirement on the size of the space, the utilization rate of the space is smaller, and the pipeline arrangement is very difficult especially for equipment with compact structure and tense space, such as a small road sweeper and the like.

(III) contents of utility model

The utility model discloses a road sweeper suction pipe structure vehicle which can meet the requirements of conveying materials such as solids, liquids and the like and improve the space utilization rate of a pipeline; the pipeline design in the form has small requirement on the size of the space and high utilization rate of the space, and the pipeline arrangement is very obvious in advantage especially for equipment with compact structure and tense space, such as a small road sweeper and the like.

In order to solve the technical problems, the utility model provides a suction pipe structure of a road sweeper, and in order to achieve the purpose, the utility model provides the following scheme: the pipeline comprises an outer pipeline and an inner pipeline, wherein the outer pipeline surrounds the inner pipeline in the diameter direction, a cavity for conveying materials such as solid or liquid is formed on the wall body of the inner pipeline, a conveying cavity for gas is formed between the outer pipeline and the inner pipeline, and the material conveying cavity and the gas conveying cavity are independent cavities which are mutually isolated; or at least two strip-shaped clapboards are arranged between the outer pipeline and the inner pipeline along the direction of the pipe body, the strip-shaped clapboards are radially connected with the outer wall of the inner pipeline and the inner wall of the outer pipeline, and the transmission cavity is divided into at least 2 independent gas transmission channels. Therefore, the conveying of materials such as solids, liquids and the like can be met, the space utilization rate of the pipeline can be improved, meanwhile, the outer pipeline is divided into a plurality of independent sub-gas conveying channels, the outer pipeline can be better utilized to convey gas, even if one sub-gas conveying channel has a gas leakage phenomenon, other sub-gas conveying channels can also provide enough gas pressure and gas flow, the conveying of the materials such as solids, liquids and the like is not influenced by the structure, the space utilization rate of the pipeline is improved, and the structure is more compact, so that the purpose of the utility model is realized.

The utility model is also characterized in that the end of the inner conduit has an end conduit with an inside diameter greater than the inside diameter of the inner conduit.

The utility model is also characterized in that the inner diameter of the inner pipe end section pipe is matched with the outer diameter of the inner pipe socket part.

The utility model is also characterized in that the pipe end of the outer pipe has a section of end pipe with an inner diameter larger than that of the outer pipe.

The utility model is also characterized in that the inner diameter of the pipe at the end of the outer pipe is matched with the outer diameter of the sleeved part of the outer pipe.

The utility model is also characterised in that the outer pipe diametrically surrounds the inner pipe.
