Height-adjustable shrub pruning device

Abstract

The invention relates to the technical field of shrub pruning, in particular to a height-adjustable shrub pruning device. The cutting device comprises a supporting device, a pair of transmission assemblies installed on the two sides of the top end of the supporting device and a cutting assembly installed at the top end of the supporting device, the supporting device comprises a base plate, adjusting plates are rotationally connected to the two sides of an operation table, the cutting assembly comprises a pair of rotating wheels, a cutting chain is rotationally connected between the two rotating wheels, and U-shaped connecting rods are connected to the bottom ends of the rotating wheels. The bottom end of the U-shaped connecting rod is connected with a hydraulic rod. According to the shrub cutting device, a hydraulic rod drives two adjusting plates to rotate towards the two sides through a transmission assembly, the top end of a cutting chain is in an open state, meanwhile, the adjusting plates rotate to the top end of a collecting box, cut shrub chippings are collected to the inner end of the collecting box through the adjusting plates, and after cutting is completed, the hydraulic rod drives the cutting chain to restore to the original shape; and the two adjusting plates are fixed at the top end of the cutting chain again to protect the cutting chain.

Description

technical field [0001] The invention relates to the technical field of shrub trimming, in particular to a height-adjustable shrub trimming device. Background technique [0002] Shrubs are woody plants without an obvious trunk. The plants are generally short, no more than 6 meters. From the place near the ground, there are clusters of horizontal branches, all of which are perennial. It is generally a broad-leaved plant, and some coniferous plants are shrubs, such as juniper. If the ground part dies during overwintering, but the roots are still alive, and new branches continue to sprout in the second year, they are called "semi-shrubs", such as some artemisia plants. , is also a perennial woody plant, but it dies in winter. Shrubs are generally used as green plants in urban gardens. During the cultivation process, the growth state of shrubs is required to be kept uniform, so operators are often required to trim them. [0003] Most of the existing shrub pruning devices carry s...

Problems solved by technology

[0003] Most of the existing shrub pruning devices carry scissors manually for pruning. During the pruning process, due to the different heights of the shrubs, the operator needs to manually adjust the height To adapt, at this time, the operator needs to lift the arm for a long time, and needs to rest after pruning for a period of time, resulting in a greatly reduced pruning efficiency. At the same time, most of the debris generated during the pruning process will fall to the ground with gravity, requiring operation Personnel carry out secondary cleaning, thereby increasing the workload of operators
