Automatic hole digger for planting seedlings

Abstract

The invention discloses an automatic hole digger for planting seedlings. The automatic hole digger comprises a vehicle body, wheels, a hole digging device and a hydraulic system, wherein the hydraulic system is used for controlling the hole digging device; the hole digging device comprises a first machine arm, a second machine arm articulated with the first machine arm and a telescopic arm telescopically mounted in the second machine arm; one end, stretching out of the second machine arm, of the telescopic arm is connected with a digging cylinder; the digging cylinder is in transmission connection with a driving motor arranged in the second machine arm through a driving shaft mounted in the telescopic arm and the second machine arm in a penetration manner. Compared with the prior art, the problems that the time of a planting hole digging process is long, the invested labor cost is high, and time and energy are wasted during transplanting trees are solved; the automatic hole digger is short in time of the planting hole digging process; planting holes can be rapidly dug by operating the hole digger by one man; the planting time is greatly shortened; the efficiency is improved.

Description

technical field [0001] The invention relates to the field of greening auxiliary devices for planting seedlings, in particular to an automatic digging machine for planting seedlings. Background technique [0002] As people pay more and more attention to the quality of the living environment, various ministries and commissions of the country have raised the requirements and standards for the greening of the urban environment, and put forward higher requirements for the efficiency of seedling planting in environmental protection greening projects. [0003] Existing greening projects usually plant finished trees or semi-finished trees in order to obtain a more obvious greening effect in a short period of time and achieve the purpose of rapidly increasing the greening area. However, due to the large size of finished trees, in order to ensure the survival rate of transplanting, local soil is usually reserved at the roots of the trees, so as to ensure that part of the root system w...

Problems solved by technology

[0005] The purpose of the present invention is to provide an automatic digging machine for seedling planting, which is used to solve the problem of low excavation efficiency of seedling planting pits in the prior art, which takes a long time and is not conducive to the development of batch green planting. The method of mechanical excavation can quickly excavate and plan the planting pits required for seedling planting, and can dig planting pits with a large depth, so as to solve the problem of overturning and tilting of trees due to insufficient depth of existing planting pits, resulting in death of trees transplanted The problem
