Problems solved by technology

[0002] With the development of economy and technology, more and more pipelines are laid for communications, cables, gas, tap water, and sewer pipes, and some trenches do not need to be dug very wide, and the current trenching machinery cannot dig narrow trenches. The same is true, because people need to go down and tools have to go down at the same time, so the ditch has to be dug wider, which increases the amount of earthwork excavated, which wastes human resources and increases the workload of post-construction cleaning. Hard asphalt roads need to be cut with equipment with cutters first, and then excavated. The work efficiency is very low. There are also some trenching machines, which need to dig a certain distance first, and then the trenching machine will be lowered. Go to the ditch and work again

Abstract

The invention relates to an excavator for ditching. The excavator comprises a spiral cutter and a guide plate arranged on the outer side of the spiral cutter, wherein the guide plate is connected witha guide plate support by an adjusting bolt, and the guide plate support is provided with an oil cylinder connecting shaft connected with a hydraulic thrust oil cylinder by a piston rod; the back endof the cutter shaft of the spiral cutter is provided with a spline shaft connected with a hydraulic motor; the outer part of the joint of the cutter shaft and the spline shaft is provided with an anti-opening sleeve, and the dent of joint of the cutter shaft and the spline shaft is provided with an opening retaining ring; and the back side of the upper spiral cutter of the upper support plate is provided with the connecting shaft. The excavator has the advantages of less workload of excavation, high excavating speed, simple structure, low manufacturing cost, convenient and safe use, convenientapplication and broad market prospect.

Background technique [0002] With the development of economy and technology, more and more pipelines are laid for communications, cables, gas, tap water, and sewer pipes, and some trenches do not need to be dug very wide, and the current trenching machinery cannot dig narrow trenches. The same is true, because people need to go down and tools have to go down at the same time, so the ditch has to be dug wider, which increases the amount of earthwork excavated, which wastes human resources and increases the workload of post-construction cleaning. Hard asphalt roads need to be cut with equipment with cutters first, and then excavated. The work efficiency is very low. There are also some trenching machines, which need to dig a certain distance first, and then the trenching machine will be lowered. Go to the ditch and work again.
