A reverse circulation trencher

Abstract

The invention discloses a reverse circulation ditching machine, which comprises a moving mechanism and a ditching mechanism. The moving mechanism includes a bottom plate, a fixed plate, a support rod, a T-shaped bar, a mounting plate, a storage battery, a moving wheel and a support plate two. A fixed plate is vertically arranged at the middle position of the top of the base plate, and both ends of the top of one side of the fixed plate are obliquely provided with support rods, and the other end of the support rod is welded to the top of the base plate, and between the two support rods A T-shaped bar is horizontally arranged at the middle position of the . The invention changes the trenching operation mode of the existing trenching machine, reduces the contact area between the scraper assembly and the soil, and reduces the resistance, that is, the front end of the excavating part is inclined, and when the invention is driven by the driving rotation, only the front end of the excavating part of the present invention is The scraper assembly is in contact with the soil, and because the soil is in the same shape as the excavating piece, when the invention is driven by the driving rotation, the soil at the top of the excavating piece is easily taken out by the scraper assembly because the bottom of the soil is hollowed out.

Description

technical field [0001] The invention relates to the technical field of trenching machines, in particular to a reverse circulation trenching machine. Background technique [0002] Trench digging machine is a device for digging trenches, which can be used in construction projects to dig narrow and deep underground trenches to bury underground drainage pipes, or to bury cables and pipes in railways, post and telecommunications, urban construction and other departments. It can also be used in orchards, vegetable gardens and other farmland environments for digging fertilization, drainage and irrigation. [0003] At present, most of the trenchers on the market are chain trenchers. Connecting plates are installed on the chain links of the transmission chain of chain trenching machines, and trenching knives are evenly installed on the connecting plates. The power system drives the transmission chain to run. Dig trenches. This kind of chain trencher has high trenching efficiency, s...

AI Technical Summary

Problems solved by technology

This kind of chain trencher has high trenching efficiency, simple structure, and reliable use. However, during use, one end of the chain trencher is inclined downward, and the traction device drives the chain trencher to move away from the chain trencher. One side moves, which virtually increases the contact area between the chain trencher scraper and the ground, increases the load on the transmission chain, and affects the trenching efficiency and the service life of the trencher
