Guiding pipe specialized device for suction nozzle/suction disc of cleaning vehicle/sweeping vehicle

Abstract

The invention provides a guiding pipe specialized device for a suction nozzle / suction disc of a cleaning vehicle / sweeping vehicle. The guiding pipe specialized device comprises the suction nozzle / suction disc and a guiding pipe for conveying sewage or dust; a fixing frame is used for fixing the upper portion of the guiding pipe on an auxiliary vehicle frame; the upper portion and the lower portion of the guiding pipe are a fixing pipe body and a flexible pipe body; a lower connector of the fixing pipe body is rigidly connected with a box body, and the lower connector of the fixing pipe body and the box body both can rotate around a rotating shaft; the flexible pipe body is used for communicating with the suction nozzle / suction disc; the upper portion of the fixing pipe body is divided into an upper guiding pipe main body and a lower guiding pipe main body; the upper guiding pipe main body is fixed on the fixing frame; the lower guiding pipe main body (15) communicates with the flexible pipe body; and the upper guiding pipe main body and the lower guiding pipe main body are in the L-shaped bent state, and the bending inner angle of the upper guiding pipe main body and the lower guiding pipe main body is smaller than 180 degrees and larger than 90 degrees. The guiding pipe specialized device has the advantages that simplicity is achieved, efficiency is high, the airtight state is always kept, and the using effect is guaranteed, and the disadvantages that an elastic object is limited in sealing range, after aging, hardening and abrasion, correction cannot be conducted in time, and thus performance of the elastic object is reduced are overcome.

Description

technical field [0001] The invention relates to a new type of special device for a new urban road cleaning vehicle / sweeping vehicle, in particular to a special device for a catheter for road cleaning or road sweeping. Background technique [0002] At present, there are mainly two types of equipment used for domestic urban road cleaning, namely washing and sweeping vehicles and road sweeping vehicles, as well as vacuum vehicles, dry sweeping vehicles, and wet and dry vehicles derived from them, but the main principle of their work is The same, all rely on the negative pressure generated by the fan to inhale the sundries, dust and sewage on the road through the airtight box, pipes, suction nozzles / suction cups and connected accessories, and collect them in the garbage bin for centralized treatment. Its dustbin can be tipped over like an ordinary dump truck to unload the dirt; the dustbin is not only a place where negative pressure passes but also a place where dirt is collecte...

AI Technical Summary

Problems solved by technology

[0004] The shortcomings of the above structure: the box interface and the pipeline are fixed on different parts, and there are mutual movement requirements; it is difficult to ensure that the two planes are completely parallel and tightly sealed due to manufacturing and other reasons. Although there is rubber between the two soft objects

It can only be improved, but cannot fundamentally solve the problem. On the one hand, the sealing range of this elastic material is limited, and on the other hand, it is easy to age, harden, and cannot be corrected in time after wear and tear to reduce its performance. The gap caused by the displacement of the box cannot be eliminated at any time, which will always affect the use effect of the whole vehicle
