Reverse circulation trencher

Abstract

The invention discloses a reverse circulation trencher which comprises a moving mechanism and a trenching mechanism, wherein the moving mechanism comprises a bottom plate, a fixing plate, supporting rods, a T-shaped rod, a mounting plate, a storage battery, a moving wheel and a supporting plate II. The fixing plate is vertically arranged in the middle position of the top of the bottom plate, the supporting rods are obliquely arranged at two ends of the top of one side of the fixing plate, the other ends of the supporting rods are welded to the top of the bottom plate, and the T-shaped rod is horizontally arranged in the middle position between the two supporting rods. The reverse circulation trencher changes a trenching operation mode of an existing trencher, reduces the contact area of ascraper assembly and soil and reduces resistance, that is the front end of an excavating part inclines. Only the front end scraper assembly of the excavating part is in contact with soil when the reverse circulation trencher is driven by driving rotation, and meanwhile, as soil is consistent with the excavating part in shape, when the reverse circulation trencher is driven by driving rotation, asthe bottom of soil is hollowed, soil located on the top of the excavating part is easily taken away by the scraper assembly.

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
