Suction type sewer scavenger with excavating

Abstract

The invention provides a suction type sewer scavenger which comprises a chassis, a vacuum unit, a filter device, a rotating device, a suction arm, a discharging device and a storage tank. The rotating device is arranged on the central axis of the chassis. When rotating around the first central axis, the rotating device can drive the suction arm, the discharging device and the storage tank on a support to rotate, so that omnibearing excavation, suction and discharging of the suction type sewer scavenger are realized. The inner cavity of the storage tank can be sucked until vacuum by the vacuum unit through the filter device, and the suction arm sucks sewer to be removed into the storage tank by the aid of the pressure different between the inner cavity of the storage tank and the atmosphere. The suction arm has a certain excavating and breaking function. During discharge, the discharging device can turn over the storage tank and discharge sewer by its gravity. The suction type sewer scavenger is small in occupation space, has a loading and transporting function, can multidirectionally excavate soil for discharging and is more accordant with requirements for municipal construction.

Description

technical field [0001] The invention relates to a suction device, in particular to an excavation and suction vehicle for excavating, suctioning, transporting and unloading materials such as soil, gravel, powder and the like by means of suction. Background technique [0002] With the development and expansion of the city, there are more and more related municipal engineering construction and maintenance work, such as civil construction, water supply, power supply, gas supply and other municipal pipe network construction, as well as building protection and public facility maintenance. These tasks require very precise excavation work, because these work sites often have interlaced cables, pipelines, etc., and damage must be prevented; in addition, due to urban space constraints, many general-purpose excavation equipment cannot be driven into the construction site or for underground construction. However, the efficiency of traditional manual excavation is very low, and a la...

Problems solved by technology

[0003] Patent ZL201020170173 discloses an intelligent multifunctional combined sewage suction truck, which can realize the suction, transportation, and unloading of sewage, sludge, sand and gravel, and large lumps, but the following problems cannot be effectively solved: 1) due to the structure Due to the limitation, the excavation of the materials, especially the compacted materials, cannot be realized, and the relevant excavation work needs to be done manually; 2) The storage tank has no auxiliary unloading device, and can only be unloaded by forced discharge, which consumes a lot of time 3) For solid materials adhering to the storage tank, it cannot be unloaded cleanly; 4) Although the suction arm can rotate and lift, its structure is not flexible and manual operation is still required Precise positioning of the hose, time-consuming and labor-intensive

Other patents that have been published so far are still focused on the field of traditional sewage suction trucks, and the new equipment and technology that integrates excavation and suction functions mentioned in this patent are not mentioned.
