Description

Technical Field

[0001] This utility model relates to the field of garden machinery, specifically to a garden pruning machine. Background Technology

[0002] With the acceleration of urbanization and the continuous expansion of green space, the demand for garden maintenance and pruning equipment is also increasing. Traditional garden pruning tools, such as shears and manual pruning saws, are inefficient and labor-intensive when dealing with large or high-lying branches, making them unsuitable for modern garden maintenance. Therefore, garden pruning equipment with higher levels of mechanization and automation is gradually becoming the mainstream in the market.

[0003] Existing garden mowers can be broadly categorized into two types: one type uses linear cutting elements (such as nylon or metal wires), primarily for trimming lawns or low-lying vegetation; the other type employs blade-type cutting devices, suitable for trimming thicker branches. However, these traditional designs have certain limitations, such as limited cutting diameter, difficulty adapting to complex and changing garden environments, and insufficient operational flexibility.

[0005] The trimming assembly includes a mounting plate, saw discs, and a pull rod. The mounting plate is rotatably connected to a lifting drive device. The saw discs are rotatably mounted on the mounting plate. One end of the pull rod is rotatably connected to the end of the mounting plate away from the frame, and the other end of the pull rod is rotatably connected to a commutator. There are four saw discs arranged longitudinally in a staggered manner.

[0011] Due to the adoption of the above technical solution, the advantages of this utility model compared with the prior art are:

[0012] This invention features a pruning assembly consisting of four cutting saw blades, with lifting and angle adjustment via a lifting drive. This design not only improves cutting efficiency and precision but also allows for flexible adjustment of cutting height and angle according to different operational needs, greatly enhancing the adaptability and ease of operation of the equipment.
