Description

Technical Field

[0001] The utility model relates to the technical field of drainage pipe laying equipment, in particular to a grooving device for laying urban drainage pipes. Background Art

[0002] Drain pipe is a new type of plastic pipe with corrugated appearance formed by adding other additives to high-density polyethylene (HDPE). The permeable corrugated pipe is made by punching holes in the grooves and wrapping the outer periphery of the pipe with needle-punched geotextile. According to the type of corrugated pipe, it can be divided into single-wall permeable corrugated pipe and double-wall permeable corrugated pipe. Because the pipe hole of this product is in the trough and is long and strip-shaped, it effectively overcomes the disadvantage that the flat round hole product is easily blocked and affects the drainage effect.

[0003] After searching, the existing Chinese patent announcement number is: CN 217896613 U, which provides a grooving device for laying drainage pipes. The patent drives the protective frame to move downward by opening the electric telescopic rod, and the protective frame drives the motor and the V-shaped bracket to move downward, drives the grooving teeth to move downward, turns on the motor to drive the chain to rotate, drives the grooving teeth to rotate, and grooves the ground. The function of the protective plate is to prevent soil from splashing. The conveyor belt transmits the soil brought by the grooving teeth and drops it on the guide plate, so as to achieve the effect of cleaning the soil. This solves the problem that the existing grooving device may cause soil accumulation and affect work efficiency due to the lack of a transmission mechanism in actual use.

[0004] Although the above patent can achieve the effect of cleaning the soil, the above-mentioned grooving device for laying drainage pipes still has the following problems: the widths of the drainage pipes are different, and drainage grooves of different widths need to be opened.
