Small mechanical fast tree digging machine

Abstract

The invention discloses a small mechanical fast tree digging machine. The machine consists of a tree digging device, a soil ball diameter adjustment and hoisting rotation device, a rope winding device, a trolley, a charging battery pack, an inverter, a hydraulic system box and a control system box. The tree digging device is composed of a first cubic fixing arm, a first cubic retractable arm, an end cover, a first amplitude-changeable hydraulic oil cylinder, a first multilevel retractable sleeving-type oil cylinder and a double-row sprocket tooling assembly. The diameter at breast height of atrunk can be automatically measured, and the diameter and taper angle of each soil ball are automatically adjusted. The soil balls can be quickly cut, and the standard quality of the soil balls is high. The soil balls can be automatically hoisted up and wound by ropes; nursery stocks can be automatically loaded onto conveying vehicles. Intelligent control and automated operation are easily achieved, operation is convenient, and the work efficiency during seedling lifting is high.

Description

technical field [0001] The invention relates to a tree digging machine, in particular to a small mechanized fast tree digging machine. Background technique [0002] In the process of urban greening and garden landscape construction, a large number of seedlings with different diameters at breast height need to be excavated from nurseries and transplanted to the side of urban streets or in garden landscapes. The ball shape and size requirements are different. It is necessary to hoist the soil ball and wrap it with a rope. The manual operation is not only labor-intensive, low-efficiency and high-cost, but also the quality of the seedling soil ball is difficult to guarantee. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a small mechanized fast tree digger. [0004] The invention is composed of a tree digging device, a soil ball diameter adjustment and its lifting and rotating device, a rope winding device, a trolley, a rechargeable batte...

Problems solved by technology

[0002] In the process of urban greening and garden landscape construction, a large number of seedlings with different diameters at breast height need to be dug out from the nursery and transplanted to the city streets or in garden landscapes. In order to improve the survival rate of transplanted seedlings, the soil The shape and size requirements of the ball are different. The soil ball needs to be hoisted and wrapped with a rope. Manual work is not only labor-intensive, low in efficiency and high in cost, but also the quality of the seedling soil ball is difficult to guarantee.
