JP2000197412A - High twig cutting chain saw driven by rope - Google Patents

Abstract

PROBLEM TO BE SOLVED: To provide a high twig cutting chain saw capable of cutting high twig without up and down swaying the pipe on which the saw is installed while conventional hook having a saw fixed on the top of a pipe and cutting a branch by up and down motion of the pipe was hard to cut the high twig because of the sway of the branch. SOLUTION: This chain saw installs a spring, a recoil pulling a rope, a chain saw installed on the top of the recoil, a clutch 7 between a rope reel 3 of the recoil and a drum 6 installing a gear 5 rotating a chain 4 of the chain saw, and the gear 5 rotates only when the rope 2 is pulled. This device is pivoted to a box 9 on the axis 8, on one side a chain guiding plate 10 is installed and other a pipe holding part 11 is installed and the pipe 12 is fixed. A pipe support 14 installed on the shaft 8 or the like at the upper part of the pipe 12, and hooking on the branch at high position 13, pulling the rope 2 from the bottom of the pipe 12 the chain 4 rotates in constant direction and capable of cutting the branch 13.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a saw for cutting high branches.

[0002]

2. Description of the Related Art A conventional high-pruning saw is used in connection with a fine-pruning cutter, and is used to cut a branch by moving a pipe body up and down.

[0003]

SUMMARY OF THE INVENTION According to the present invention, tall branches can be cut without moving up and down a pipe to which a saw is attached.

[0004]

In order to achieve the above object, it is an object of the present invention not to fix a saw to a pipe to be expanded or contracted or added. For this purpose, it is preferable to attach a chain saw to the upper part of the pipe body. However, it has a drawback that the motor of the chain saw becomes heavy and the wires are pulled, and even if the motor is turned by a battery, the motor does not last long. According to the present invention, the chain is turned by the action of a recoil using a spring and a rope in place of the motor.

[0005]

DESCRIPTION OF THE PREFERRED EMBODIMENTS In order to start a small engine or the like, the engine can be turned by the repulsive force of a spring by a cell motor or a recoil and the action of pulling a rope. It is like turning the chain of Chien Sa. The center of the spiral spring (1) of the recoil and the center of the rope reel (3) for winding the rope (2) are connected, and when the rope (2) is pulled, the rope reel (3) is turned. The center of the spiral spring (1) turns and the spring is tightened inward. Next, when the rope is loosened, the rope (2) is wound around the rope reel (3) by the repulsive force of the spring. In this state, the rope reel (3) rotates forward and backward, so that the rope reel (3)
A clutch (7) is provided between the chain (4) and a drum (6) to which a gear (5) for rotating the chain (4) is attached, and a clutch (7) is attached so that the gear (5) rotates only when the rope (2) is pulled.

A spiral guide (1), a rope reel (3), a clutch (7), a drum (6), a gear (5), and a box (9) provided with a shaft (8) are provided on one of the boxes (9). 10) is attached, and the other one is provided with a pipe holding part (11). The chain (4) of the chain is set on the chain guide plate (10) and the gear (5), and the pipe (12) is attached to the pipe holding part (11). In order to lengthen the pipe, the pipe support (14) is fixed to the shaft (8) or the like, and the pipe support (14) is hooked on the tall branch (13). The rope (2) is pulled under the pipe (12), but if you wrap it around your hand and it will hurt your hand, the rope hole (16) in the hook-type rope clasp (15) as shown in Fig. 3
The rope (2) is passed through, and wrapped around the L-shaped part (17), and the rope is pulled together with the rope (2). With the above structure, once the pipe is supported on the tall branch, the branch can be cut off without supporting the weight of the pipe until the branch is cut off. The conventional chain saw has a blade shape suitable for high-speed rotation, but the blade chain of the present invention preferably has a blade shape for low-speed rotation.

[0007]

According to the present invention, the conventional high-pruning saw has a saw fixed at the tip of the pipe, so that the entire pipe is moved up and down to cut the branches. Did not. This invention cuts high branches with a chain using a recoil attached to the tip of a long stretched pipe, but it is not necessary to move the pipe up and down, cutting branches regardless of the weight of the pipe by hanging the pipe support on the branch I can do it.
