Description

  The two inventions relate to an electric chain saw with an outrigger that makes it easy to cut a trunk or a branch with a chain saw in a tree pruning operation, and an electric chain saw for a high branch that prunes a trunk or a branch of a high branch from the ground.

  The chain saw is easy to cut a trunk of a large tree, but when cutting a tree trunk or branch, it may not be easily cut without being cut by the saw blade of the chain saw. It is.

  Patent No. 3930545 obtained by the applicant The high branch electric hair clipper has a function to cut off the surface of planting and the like together when pruning, but cannot cut the trunk or branch of the high branch from the ground. Invented is a high branch electric chain saw in which the newly invented electric chain saw with an outrigger is attached to the electric hair clipper.

Patent No. 3930545 obtained by this applicant,
1. In the tree pruning work, the arm and the electric pruning are done at the tip of the fence in order to ensure efficient operation by securing a position where the person is on the ground and the high branch is wide, and the line of sight is visible from a low position. Attach a clipper with an arm that is 100 to 150 cm in length and integrate a small clipper, and adjust the angle of the clipper with an arm by using the weight of the clipper part and pulling a string-like object tied to the other end of the arm. An electric hair clipper for a high branch, characterized by

  2. The angle of the pruning surface of the electric pruning small hair clipper can be adjusted from the horizontal direction to the vertical direction, and in order to facilitate operation at a position away from the electric pruning small hair clipper, For attachment to the heel, make joints with bolts in the holes in both the middle part of the clipper with arm and the attachment part of the heel, and use this joint hole as a fulcrum to adjust the angle of the clipper with arm by electric pruning Because the weight of the clipper is adjusted by pulling the string at the other end of the arm lightly, the joint hole is adjusted so that the electric pruning small clipper is slightly heavier and the operability is at the optimal position. The string-like object tied to the other end of the arm is passed through a pulley on the collar, and a fastener that can adjust the length of the string-like object is attached below the string-like object. For Takada Dynamic clippers.

  3. For the purpose of reducing the disconnection and entanglement of the power cord that is the power source, the power source is electrically connected by attaching a socket near the electric pruning small hair clipper and pulling the cord from the upper side to the lower side in the eaves. 2. The electric branch clipper for high branches as set forth in claim 1, wherein sockets are attached to both ends, and a switch is attached to an appropriate position of the bag to enhance safety.

Japanese Patent No. 3930545 JP 11-75543 A JP 2002-65061 A JP 2003-199430 A

  An object of the invention of an electric chain saw with an outrigger is to provide a device for improving this in some cases where the saw blade of the chain saw is not applied when cutting a trunk or a branch, so that it may not be easily cut.

  Also, the pruning work that climbs the ladder has a risk of falling, the pruning device for high branches is very low in efficiency, the electric pruning equipment is heavy to operate at high places, and there are many dangers such as cutting the power supply cord in the work . An object of the invention of an electric chain saw for high branches is to provide a device capable of safely and efficiently pruning a trunk or a branch of a high branch from the ground.

  The electric chain saw with outriggers has two holes in the chain guide plate of the electric chain saw. This is done by combining and fixing the circular gear and the circular gear at the upper end of the outrigger. The outriggers are wound around the saw blade so as not to contact the saw blade of the chain saw, and the lower base and the circular gear at the upper end are integrated into a single structure. Make it uneven.

  In order to cut the trunk and branch of a high branch from the ground, the high branch electric chain saw is a newly-invented electric chain saw with an outrigger, instead of the electric pruning small clippers with arm clippers in the patent No. 3930545 electric clippers for high branches. Install.

  According to the invention of the electric chain saw with an outrigger, the trunk and the branch are easily hooked on the saw blade of the chain saw and can be easily cut, and the application range of the present invention is expanded.

  In addition, the invention of the electric branch saw for high branches allows safe pruning work within the reach of the equipment and eliminates the need for a ladder to cut the trunk and branches of the high branches. When pruning high branches by working on the ground, the equipment can be kept stable and can be easily pruned from vertical to horizontal.

  One embodiment of the present invention is shown in FIGS.

Each part will be described as follows on the drawing.
In FIG. 1, by adjusting the angle between the saw blade 1 and the outrigger 5 of the chain saw, the saw blade bites into the trunk or branch.

  FIG. 2 The rotation of the pedestal is stopped by aligning the bolt hole of the pedestal 7 with the rotation stop projection 9 of the pedestal in the two holes 9 on the chain saw guide plate 2, and the outrigger is rotated by the circular gear on the pedestal and the circular gear on the upper end of the outrigger. Adjust the angle.

  In FIG. 3, the chain saw 2 is moved up and down by pulling the string 15 to adjust the angle.

Since the electric branch saw for high branches has a reach by the arm, the cutting portion may be about 20 cm, and the chain saw can be miniaturized, which makes it easy as a high branch pruning instrument.

An electric chain saw for high branches can be enlarged by devising a trolley and pedestal. It can be fixed on the car and used to hang down the roadside tree. Will be active.

It is an overhead view of an electric chain saw with an outrigger. It is sectional drawing of an outrigger fixed part. It is an electric chain saw perspective view for high branches. It is an overhead view of the arm of an electric chain saw for high branches It is a side view of the arm of an electric chain saw for high branches.

Claims (4)

  In order to make it easier to cut trunks and branches with a chain saw in tree pruning work, the angle can be adjusted by turning the saw blades from the top and bottom of the chain guide plate, and there is an outrigger with a non-slip notch on the surface in contact with the trunk and branches An electric chain saw with an outrigger.   In order to cut high-trunk trunks and branches from the ground efficiently, a chain saw with an arm with a length of 100 to 150 cm integrated with an electric chain saw with an outrigger is attached to the tip of the fence.
