Detailed Description
Compared with the existing pit digging mechanical equipment, the pit diameter of the pit dug by the pit digging equipment can be adjusted and changed according to actual requirements, the adjusting process is full-automatic, an operator only needs to turn off the engine after the pit diameter meets the requirements and then manually turn off the on-off switch, the whole process is simple and quick to operate, the operator does not need to worry about labor and labor, and the pit digging equipment is simpler and more convenient; this equipment of digging pit adopts outside digging pit to go on with central digging pit simultaneously, and the earth that the central digging pit produced can be pushed down the outside and its final and outside earth together transported to a section of thick bamboo that unearths and discharges, avoids digging pit in-process earth to splash and causes the injury to operating personnel.
