Pruning manipulator for hedge seedlings

Abstract

The invention relates to a pruning manipulator for hedge seedlings, in particular to a pruning manipulator capable of automatically pruning hedges and trees into various shapes such as sphere, cylinder, cone, plane, waved surface and the like. The pruning manipulator comprises a carrier and a hedge seedling pruning manipulator which is mounted above the carrier and has five degrees of freedom and six degrees of motion. The pruning manipulator can automatically prune landscape trees into various shapes such as sphere, cylinder, circular truncated cone and the like and prune hedges into plane, inclined surface and the like, the inclination angle of a pruning tool can be adjusted freely, and the pruning tool is fixed at an output shaft end of a tool inclination angle adjusting mechanism and can rotate freely and flexibly.

Description

technical field [0001] The invention relates to a manipulator for trimming hedgerow seedlings, in particular to a manipulator for trimming hedgerows and trees in various shapes such as spheres, cylinders, cones, planes and waves. Background technique [0002] At present, the pruning and modeling of hedge trees in China is mainly carried out by hand-held hedge trimmers or scissors, which is labor-intensive and low-efficiency. With the acceleration of my country's urbanization process and the advancement of road construction, the pruning and modeling of hedge seedlings has become a regular work in landscape greening operations. On the one hand, it is reflected in the pruning of road green belts, and on the other hand, it is reflected in the pruning of urban garden trees. Landscape trees can stabilize the subgrade structure of the expressway, avoid direct rainwater erosion, maintain water and soil, prevent wind and sand fixation, beautify the environment, and absorb vehicle ex...

AI Technical Summary

Problems solved by technology

The main shortcomings of pruning and modeling operations on hedges and landscape trees by greening personnel's hand-held tools can be summarized as follows: first, the hedge trimmer uses a single-cylinder gasoline engine as power, and its noise is high, which often affects the normal study or work of surrounding personnel.

Second, the physical exertion of greening workers is large. Since hedges often need to be trimmed on three sides, greening workers need to hold trimmers and move them with loads.

Third, the energy consumption is high, and the air pollution is serious. The two-stroke gasoline engine commonly used in handheld hedge trimmers has low combustion efficiency and emits a large amount of toxic and harmful gases such as carbon monoxide and sulfur dioxide.
