Dredging vehicle for cleaning municipal sewer stones

Abstract

The invention discloses a dredging vehicle for cleaning municipal sewer stones. The dredging vehicle for cleaning municipal sewer stones comprises a hopper, wherein the top end of the hopper is provided with a flushing device, a stone cleaning device and a mud discharging device, the stone cleaning device includes a movable garbage bin mounted on the hopper and a garbage conveying mechanism, the garbage conveying mechanism comprises a suspension transverse rail which is arranged at the top end of the vehicle hopper through a U-shaped mounting rack, the top end of the U-shaped mounting rack isfastened on a first oil cylinder at the left end of the suspension transverse rail through an oil cylinder seat, the right end of the first oil cylinder is connected with a sliding block matched withthe suspension sliding rail through a piston rod, the inner part of the sliding block is provided with a second oil cylinder through a mounting layer, and the bottom end of the second oil cylinder isconnected with an automatic garbage sweeping device through a piston rod, so that the height of the suspension transverse rail is higher than the height of the first oil cylinder, accordingly the sliding of the oil cylinder driving sliding block is smoother.

Description

technical field [0001] The invention relates to the field of municipal sewer cleaning, in particular to a dredging vehicle for cleaning municipal sewer stones. Background technique [0002] The sewer is a kind of urban public facility, which appeared as early as the ancient Roman period. Generally speaking, the sewer system is used to collect and discharge domestic wastewater generated by cities and industrial wastewater generated by industrial sewers. [0003] The existing municipal sewer dredging methods are as follows: [0004] (1) Precipitation and drainage: Use a mud pump to discharge the sewage in the inspection well to the bottom sludge. The pipeline that needs to be dredged is divided into sections, and the method of segmentation is distributed according to the pipe diameter and length. There is a section between two inspection wells with the same pipe diameter. (2) Dilute the sludge: the high-pressure water truck pours water into the well chamber from the two ins...

AI Technical Summary

Problems solved by technology

[0008] (1) There are sewer mouths all over the city roads. If the sewer mouths are blocked by garbage, the waste water on the roads in rainy days will not be discharged into the sewers. The garbage will rot in the sewers and give off a bad smell, which will affect the air quality and city appearance. At present, the sewers have not been cleaned The device at the mouth of the well measures the oxygen content in the well before the personnel enter the inspection well. The construction personnel must wear safety belts, gas masks and oxygen tanks before entering the well before entering the sewer for cleaning. It consumes a lot of manpower and cost, and the cleaning steps are complicated and time-consuming. also more;

[0009] (2) Although the current dredging vehicle can suck out the silt and sewage in the sewer, the stones deposited in the sewer or the soil clods bonded to the bottom of the sewer cannot be cleaned, so the sewer is not clean enough, Incomplete, municipal sewers are still easily blocked by garbage
