Pit digging apparatus used for tree planting in gardens and convenient to adjust

Abstract

The invention discloses a pit digging apparatus used for tree planting in gardens and convenient to adjust. The pit digging apparatus comprises a fixed plate and a lifting plate, wherein two frames are fixedly mounted at the left and right ends of the fixed plate; the left and right ends of the lifting plate are slidably mounted at the inner sides of the two frames; the bottom of the fixed plate is provided with a groove; a rotating rod is rotatably arranged in the groove; two external threads with opposite screwing directions are symmetrically arranged on the left and right sides of the rotating rod; a screw is rotatably mounted on the bottom of the lifting plate; and the outer side of each frame is successively provided with a dedusting case and an exhaust fan from top to bottom. According to the invention, the lifting plate is driven to move up and down by using the rotating rod having the external threads with opposite screwing directions, and the screw is arranged to drive a drilling rod to move left and right, so an operator does not need to hold the pit digging apparatus with the hand and stoop down to carry out pit digging; the pit digging apparatus is easy to use and convenient to operate; and the exhaust fans and the dedusting case are arranged to absorb dust generated in pit digging so as to ensure the health of operators.

Description

Technical field [0001] The invention relates to the technical field of garden equipment, in particular to a digging device for garden tree planting which is convenient for adjustment. Background technique [0002] The beautiful natural environment and recreational area created by the use of engineering technology and artistic means in a certain area by transforming the terrain, planting trees and flowers, constructing buildings, and laying out garden roads are called gardens. Gardens include gardens, homes, small amusement parks, gardens, parks, botanical gardens, zoos, etc. With the development of the landscape disciplines, it also includes forest parks, scenic spots, nature reserves or national parks, tourist areas and recreational resorts. [0003] Before planting the trees on the road, digging is required. Currently, hand-held digging machines are generally used to dig the pits manually.

Problems solved by technology

[0003] It is necessary to dig holes before planting the trees on the garden road. At present, the pits are usually manually dug with a hand-held digging machine, so that the workers need to bend down for a long time when digging the pits, so that the workers are prone to backaches and lower back pain. At the same time, bending over for a long time is not conducive to the adjustment of the digging machine, and it is inconvenient to accurately select the digging position
