Portable Auger Tree Digger

Abstract

The invention discloses a portable tree mover based on ball screw transmission. The portable tree mover mainly comprises a rotating mechanism, a support mechanism, a ball screw transmission mechanism and a tree digging shovel, wherein four thread screwed locking rods are installed on an inner ring of the rotating mechanism, so that a whole device is fixed on a tree trunk. The inner ring of the rotating mechanism is connected with an outer ring of the rotating mechanism by a ball and a bolt, and; the outer ring can makescircular motion around the inner ring. A fixing arm of the support mechanism is connected with the outer ring of the rotating mechanism by a joint bearing,;and a telescopic arm is connected with the ball screw transmission mechanism. The other end of the ball screw transmission mechanism is inserted into the soil by a bearing seat,; the tree digging shovel is connected with a threaded rod by a sliding sleeve, and; the tree digging shovelcontinuouslydigs the soil along with the rotation of the threaded rod. The portable tree mover is simple in structure, reliable in work and convenient to carry, and can work in a narrow space and on a mountain; by adopting a ball screw transmission principle, the portable tree mover enables an operator to operate uprightly, thus lightening labor intensity.

Description

technical field [0001] The invention relates to a portable tree digging machine based on a ball screw transmission, which is used for transplanting trees in nurseries and mountainous areas, enables operators to work upright without support, and belongs to the technical field of forestry machinery. Background technique [0002] As people pay more and more attention to the quality of life and living environment, urban greening has become an essential key project in my country's infrastructure construction. Among them, tens of thousands of seedlings are needed every year for urban greening, road greening, and railway greening, which provides a broad market space for the seedling industry in our country. However, the mechanization level of seedling transplantation in my country is difficult to keep up with the vigorous development of the nursery industry. The main reasons are: (1) Large-scale tree transplanters are expensive and difficult to enter nurseries with narrow roads and...

Problems solved by technology

However, the mechanization level of seedling transplantation in my country is difficult to keep up with the vigorous development of the nursery industry. The main reasons are: (1) Large-scale tree transplanters are expensive and difficult to enter nurseries with narrow roads and dense planting and mountainous and hilly areas; ( 2) The existing domestic portable tree diggers have a heavy body and require workers to hold the tree digger and bend over repeatedly to cut the soil, which does not really reduce the labor intensity
