Multifunctional unmanned tree digging machine

Abstract

Provided is a multifunctional unmanned tree digging machine, comprising a crawler chassis (1), wherein a travel motor (6) is arranged on the crawler chassis (1), and the crawler chassis (1) is controlled by the travel motor (6) to move around; a control cabinet is arranged above the crawler chassis (1), with one side of the control cabinet being fixed on the crawler chassis (1) through a shaft (4) for up-and-down rotation of the complete machine, and with the other side being fixedly connected to the crawler chassis (1) through a tilt angle adjustment cylinder (29); and a top end of the tilt angle adjustment cylinder (29) is connected to the control cabinet, and a telescopic shaft of the tilt angle adjustment cylinder (29) is connected to the crawler chassis (1), such that the tilt angle of the control cabinet relative to the horizontal plane is driven through the telescopic motion of the telescopic shaft of the tilt angle adjustment cylinder (29), so as to drive the change in the tilt angle of a tree digging shovel assembly fixed at the front end of the control cabinet relative to the horizontal plane. A digging assembly can be tilted forward and back at a certain angle, such that it is convenient for same to travel with the tree after same has been dug. This machine makes ingenious use of the force balance principle, in which a balanced force system is formed between a bottom shovel arm (7) and a bucket shovel (10) and between a ground anchor (9) and a bottom shovel as configured, thereby omitting balance weights of the complete machine to save energy.

Description

technical field [0001] The invention relates to a tree digging machine, in particular to a multifunctional unmanned tree digging machine. Background technique [0002] Although all kinds of tree digging machines in the domestic market have their own advantages, they also have defects: wheeled tree digging machines have poor cross-country ability, and it is difficult to walk on slopes, potholes, and muddy land. Although crawler tree digging machines are suitable for different terrains Walking, but it also needs a counterweight, no matter it is a crawler type or a soft type tree digger, as long as the driver operates, there is a problem that the line of sight is not good, the position of the excavated soil ball is not accurate, causing the soil ball to be biased, the existing domestic excavator The tree digging machine can only dig trees, but not plant trees and dig holes. It can only work on flat ground, not on slopes. The width of the site is fixed and cannot be adjusted. So...

[0002] Although all kinds of tree digging machines in the domestic market have their own advantages, they also have defects: wheeled tree digging machines have poor cross-country ability, and it is difficult to walk on slopes, potholes, and muddy land. Although crawler tree digging machines are suitable for different terrains Walking, but it also needs a counterweight, no matter it is a crawler type or a soft type tree digger, as long as the driver operates, there is a problem that the line of sight is not good, the position of the excavated soil ball is not accurate, causing the soil ball to be biased, the existing domestic excavator The tree digging machine can only dig trees, but not plant trees and dig holes. It can only work on flat ground, not on slopes. The width of the site is fixed and cannot be adjusted. Some tree digging machines can only dig out the soil balls, but cannot Lifting up, lifting the soil ball requires the cooperation of the hanging tower
