Description

Technical Field

[0001] This utility model relates to the field of forestry branch pruning technology, specifically to a forestry branch pruning device. Background Technology

[0002] Forest pruning refers to the technical measures used in forestry production, forest cultivation, and ecological maintenance to selectively remove or adjust the vegetative organs of trees, such as branches, buds, and leaves, through artificial means. Its core objective is to regulate the growth and development of trees, optimize forest stand structure, improve forest quality and ecological function, while also taking into account timber production, landscape value, or protective benefits.

[0003] Currently, electric pruning machines are used to assist in pruning branches in forestry. These machines consist of an electric motor and pruning shear heads. For example, patent application number 201080065764.9, entitled "A Hedge Pruner," specifically includes an electric motor and at least two cutting blades, each blade comprising at least one row of teeth. The electric motor is connected to at least one blade so that rotation of the motor causes at least one blade to move relative to the other blade. A first user-operated switch is provided for operating the blades of the hedge pruner, and a second user-operated switch allows the user to select between at least two operating modes of the hedge pruner. These modes include: a hedge pruning mode, in which operating the first user-operated switch causes at least one blade to reciprocate; and a trimming shearing mode, in which operating the switch performs a single cutting cycle. A dual-speed gearbox can be provided to allow the blades to move at a lower speed and with higher torque in trimming shearing mode compared to hedge pruning mode.

[0004] However, the aforementioned electric trimmers can cause plant debris to splatter during the trimming process, which can cause scratches and other dangers to the trimmers, and cannot prevent or protect them.

A connecting component 3 for extending and retracting the protective cover 2 is provided between the pruning body 1 and the protective cover 2. When pruning branches, the protective cover 2 covers the upper surface of the pruning body 1 to block the splattered branches. When it is necessary to clean the inside of the protective cover 2, the protective cover 2 is extended upward through the connecting component 3 to clean it. After cleaning, the protective cover 2 is moved in the opposite direction and retracted for subsequent pruning.

[0029] Specifically, the connecting component 3 includes a U-shaped fixing seat 31 disposed on the upper surface of the trimmer body 1. The U-shaped fixing seat 31 is arranged along the width direction of the trimmer body 1 and fixed on the upper surface of the trimmer body 1 near the gripping end; a rotating rod 32 rotatably installed inside the U-shaped fixing seat 31, with rotating shafts at both ends of the rotating rod 32, which rotate through shaft holes to cooperate with the U-shaped fixing seat 31; and a connecting bracket 33 connecting the rotating rod 32 and the protective cover 2. One end of the connecting bracket 33 is fixed to the upper surface of the protective cover 2, and the other end is connected to the outer wall of the upper surface of the rotating rod 32; the connecting bracket 33 is connected between the outer wall of the rotating rod 32 and the top outer wall of the protective cover 2; and two fixing components 4 are respectively provided on both sides of the U-shaped fixing seat 31 to limit the rotation position of the rotating rod 32.
