Subsurface soil layer renewing equipment for municipal works

Abstract

The invention belongs to the technical field of a subsurface soil layer renewing technique, and particularly relates to subsurface soil layer renewing equipment for municipal works. The subsurface soil layer renewing equipment comprises a walking mechanism, mechanical arms, hydraulic pressure rods, a hydraulic motor, a transmission mechanism, a soil digging mechanism and feeding modules. The soildigging mechanism which is designed can extend downwards into a filtering soil layer on the lower side of soil to renew the filtering soil layer, and the phenomenon that after long-time use, the filtrating soil layer under the soil is clogged, can be avoided. In order to reduce consumption of the mechanical arms when the soil digging mechanism is driven by the mechanical arms to move forwards to shorten the service life of the mechanical arms, the invention designs the feeding modules, and the feeding modules can enhance the driving force of the soil digging mechanism while walking forwards. Acutting mechanism is designed, the cutting mechanism can cut off roots which are in contact by a mounting housing in the walking process, and resistance of the roots to the mounting housing during walking can be reduced.

Description

[0001] Technical field [0002] The invention belongs to the technical field of underground soil layer renovation, and in particular relates to underground soil layer renovation equipment for municipal engineering. Background technique [0003] With the acceleration of the urbanization process, the level of urban greening is gradually improving, and parks and gardens with water absorption and filtration functions have become an important aspect of future design; different soil layers are used to filter rainwater, but after long-term use, the lower soil The filter soil layer will be clogged, which will lead to hypoxia in this layer, which will accelerate the reproduction of anaerobic organisms, aggravate the clogging degree of the filter soil layer, and finally cause the filter soil layer to be difficult to infiltrate. [0004] The present invention designs a municipal engineering underground soil renovation equipment to solve the above problems. Contents of the invention ...
