Abstract

The invention discloses a chain pole type pit and trench digging operation device. One side of a frame is hinged to a support, a swinging oil cylinder is arranged between the frame and the support, anoutput device is fixed on the frame, one end of a pitching oil cylinder is connected with a chain frame, the other end of the pitching oil cylinder is connected with the frame, and the pitching oil cylinder is used for controlling an excavation mechanism to swing up and down. Through work of an excavation device, pits and trenches can be dug in the ground, the pit and trench digging depths can becontrolled by controlling the pitching oil cylinder, earth and stone dug out by the excavation device are thrown out through the output device, the arranged swinging oil cylinder can control swingingof the output device and the excavation device, and thus the pit and trench digging depths can be enlarged. The pitching oil cylinder can be driven in an electric control manner, and automatic adjustment of the driving speed is realized. The arranged excavation device can complete excavation of various kinds of soil, horse stone soil, ore beds and frozen earth.

Description

technical field

[0001] The invention relates to the technical field of engineering machinery, in particular to a chain bar type pit digging operation device. Background technique

[0002] In the process of engineering work, it is necessary to dig pits and trenches. At present, most of the existing tools for digging pits and trenches are excavators. This kind of equipment is not only inefficient but also has poor trench formation, and cannot perform pit digging operations well. Trench operating device is particularly important. Contents of the invention

[0003] The technical problem to be solved by the present invention is to provide a chain bar type pit digging operation device specially for digging pits and trenches.

[0004] In order to solve the above-mentioned technical problems, the technical solution of the present invention is: a chain bar type pit digging operation device, comprising:

[0005] A frame, one side of which is hinged to the bracket, and a swing cyl...
