Description

Multifunctional tree trimmer with replaceable blades

technical field

The invention relates to a tree pruner, in particular to a branch pruner used for clearing tree obstacles along power transmission lines.

Background technique

How to clear tree barriers along transmission lines has always been a difficult problem for transmission line operators. When the distance between high-voltage power lines and trees exceeds the specified safety distance, high-voltage lines will discharge trees. In case of rain or excessive air humidity Large, under the action of high voltage, trees will become electrical conductors, which will pose a hazard to buildings, equipment, and personnel around the trees, and may cause major equipment and personal casualties, not only causing huge losses to the country and people's lives and property, but also Make electric power enterprises helplessly involved in legal disputes and economic compensation. Now to carry out tree branch pruning work, one must use climbing tools or climb to the tree with bare hands, and use an ax and hand saw for pruning.

Contents of the invention

The purpose of the present invention is to overcome the deficiencies of the prior art and provide a multifunctional branch pruner with replaceable cutter heads, which is convenient and labor-saving, and integrates multiple functions of chopping, shearing, pruning and sawing, and can be used according to different tree species and environments. Use the corresponding replaceable cutter head for pruning to ensure a sufficient safety distance between the tree and the line to ensure the safe operation of the line.

The present invention is characterized in that it includes an insulating operating rod, an inner thread connecting screw, and a replaceable cutter head, the insulating operating rod is connected to the inner thread connecting screw, and the inner thread connecting screw is threadedly connected to the casing; the inner thread connecting screw is sequentially It is composed of a cutter head connected with an inner wire, a sleeve limit nut, a protective gasket connected with an inner wire, an operating rod inner wire protection gasket, and an operating rod connected with an inner wire; the replaceable cutter head is a multifunctional cutter head, and the lower end is a belt The sleeve pipe with internal thread has a hook head, a shovel head and a sickle at the upper end; the lower ends of the shovel head, the sickle head and the hook head are welded together on the sleeve pipe.

The replaceable cutter head is a crescent-shaped cutter head, and the upper end includes a sickle head and an ax head, and the lower ends of the sickle head and the ax head are welded together on the casing.

The replaceable cutter head is a saw-shaped cutter head with serrations, and the lower end of the saw-shaped cutter head is welded on the casing.

The replaceable cutter head is a scissors-type cutter head, including an upper cutter head and a lower cutter head, and the upper cutter head and the lower cutter head are movably connected by a pin and a return spring. The upper cutter head is welded on the casing, and the lower cutter head The tail end of the head is connected with a drawstring.

The insulating operating rod is multi-section, and each section is threaded.

It can be seen from the above-mentioned technical scheme that the present invention adopts the insulating operating rod to solve the problem of the safe distance of tree pruning, and is a simple tool for people on the ground to realize long-distance pruning of the branches on the tree; the head end of the insulating operating rod is Improvement, threaded connection with the replaceable cutter head, so that the parts can be firmly connected with the insulating operating rod, and the operation is safer and more reliable; according to different tree species and environments, the corresponding replaceable cutter head can be used for trimming: The multi-functional shovel head is used to trim upwards and remove foreign objects falling on the wire; the crescent-shaped blade is used to trim high branches; the saw-shaped blade can be used to trim thicker trees above, especially the branches close to the wire, It avoids the phenomenon that the branches swing back and forth and accidentally touches the wires; the scissors-type cutter head controls the blade clutch through the pull cord, cuts off the high-altitude branches, and is used for the pruning of high-altitude fruit trees and landscape trees and branches close to the wires; The multi-function saw is integrated, easy to use, labor-saving, and cost-saving, which improves the personal safety factor during the tree pruning process and ensures the safe operation of the transmission line during the tree pruning process.
