Description

Technical Field

[0001] This utility model relates to the field of garden construction technology, and more specifically, to a garden pruning device. Background Technology

[0002] The technological development of garden pruning equipment has always revolved around core needs such as improving operational efficiency, adapting to complex tree shapes, and reducing human risks. In existing technologies, the combination of lifting devices and cutting devices has become a key research direction for achieving automated pruning, but many technical bottlenecks still exist. For example, traditional equipment often relies on fixed support structures or manually operated lifting devices, making it difficult to adapt to changes in trunk diameter or complex canopy environments, resulting in low pruning efficiency and safety hazards.

[0003] Taking patent CN221329625U (publication date: July 16, 2024) as an example, it discloses a garden trimming device based on a trolley platform, including a height adjustment mechanism, an angle adjustment mechanism, and a trimming shear assembly. This device achieves height adjustment through a screw and motor-driven lifting seat, and controls the angle of the trimming shears through gear transmission. However, this design has significant limitations:

[0004] 1. Limited mobility: It relies on a trolley chassis for movement, and is only suitable for scenarios with flat ground and limited working height. It cannot achieve autonomous climbing along tree trunks, so high-altitude pruning still requires manual assistance.

[0005] 2. Insufficient clamping adaptability: The rigid lifting seat and fixed blade holder cannot dynamically conform to the irregular surface of the tree trunk, and are prone to clamping failure or damage to the bark due to changes in the diameter of the tree trunk; Utility Model Content

[0006] Based on this, in order to solve the problems of traditional pruning equipment: 1. limited mobility; 2. difficulty in adapting to various tree trunks of different diameters, this utility model provides a garden pruning device, the specific technical solution of which is as follows:

[0032] like Figure 1-4As shown, a garden pruning device according to one embodiment of the present invention includes a first moving device 1, a second moving device 2, and a cutting device; the cutting device includes a first rotating block 3, a second rotating block 4, and a driving component 5; both the first rotating block 3 and the second rotating block 4 are connected to the driving component 5; the outer contours of both the first rotating block 3 and the second rotating block 4 are arc-shaped; the first moving device 1 is disposed on the first rotating block 3, the second moving device 2 is disposed on the second rotating block 4, and the driving component 5 is used to drive the first moving device 1 and the second moving device 2 to clamp the tree trunk; both the first rotating block 3 and the second rotating block 4 are provided with saw teeth, which are used to cut branches on the tree trunk.

[0033] Compared to handheld high-branch pruners (which require manual height adjustment) and 15-meter boom pruning vehicles (which rely on hydraulic telescopic structures), this garden pruning equipment achieves continuous climbing through the friction between the saw teeth and the tree trunk, avoiding frequent adjustments to the equipment's position. Through the curved surface design of the first / second arc-shaped rotating blocks 4, combined with the dynamic adjustment of the clamping force by the drive component 5, it can adapt to various tree trunks of different diameters. This garden pruning equipment solves the problems of traditional pruning equipment: 1. limited mobility; 2. difficulty in adapting to various tree trunks of different diameters.
