Pit digging working head for afforestation on difficult site and working method thereof

Abstract

The invention discloses a pit digging working head for afforestation on a difficult site and a working method thereof. The pit digging working head for afforestation on the difficult site structurally comprises a rack capable of controlling feeding movement, wherein one side of the upper part of the rack is connected with a supporting plate through a connecting frame, the supporting plate is provided with a hydraulic motor, the bottom of the hydraulic motor is connected with a drill rod through a gearbox, and the bottom of the drill rod is used for mounting a drill tip or a soil cutting blade; spiral fins are annularly arranged on the side wall of the drill rod, the lower part of one side, away from the supporting plate, of the rack is mounted on a chassis hanging plate, the chassis hanging plate is used for being connected with a power chassis, and the rack further comprises a soil cleaning device used for cleaning soil on the spiral fins after pit digging is completed. According to the pit digging working head for afforestation on the difficult site, the angle and the diameter of each drill bit spiral fin of the working head and the length of the drill rod can be conveniently adjusted, a drill bit blade and the drill tip can be rapidly replaced, the working method of the working head under different afforestation working conditions improves the working safety under the conditions of hills, mountains and difficult sites, the working efficiency is improved, and the labor intensity is relieved.

Description

technical field [0001] The invention relates to the field of forestry and grassland, in particular to a working head for afforestation and digging pits on difficult sites and a working method thereof. Background technique [0002] The state attaches great importance to the construction of ecological civilization and promotes large-scale land greening and ecological restoration actions. At this stage, in flat areas and favorable working conditions, most of the digging operations can be completed with the application of engineering excavators, suspended diggers and hand-held digging tools. However, under difficult site conditions such as arid and semi-arid, rocky desertification, salinization, and steep slopes, affected by many factors such as soil characteristics, climate characteristics, and vegetation types, especially for operating conditions on slopes above 25 degrees, engineering excavators 1. It is difficult for the suspended digging machine to go up the mountain, and ...

Problems solved by technology

However, under difficult site conditions such as arid and semi-arid, rocky desertification, salinization, and steep slopes, affected by many factors such as soil characteristics, climate characteristics, and vegetation types, especially for operating conditions on slopes above 25 degrees, engineering excavators 1. It is difficult for the suspended digging machine to go up the mountain, and the hand-held digging machine relies too much on manpower, and the distance between man and machine is relatively close. low efficiency
