Remote-controlled tree felling system

Abstract

This remote-controlled tree felling system enables safe and inexpensive felling of large-diameter trees in steep mountainous areas, without requiring workers to approach the trees. [Solution] The system includes a wire saw 2 for cutting, a drone for setting it up from a high place, and a power unit 7 for towing the wire saw from a distance. The power unit 7 is fixed by an anchor 11. Furthermore, by controlling the towing direction using a pulley 5 and driving the wire saw horizontally, the blade bites into the material reliably, while the operator can operate it from a safe distance.

Description

[Technical Field] This invention relates to a system for safely felling trees in forestry, and more particularly to a system that allows workers to fell trees safely via remote control without having to approach the trees. [Background technology] Traditional logging operations require workers to approach trees with chainsaws, resulting in a high risk of tree-falling accidents. The problem this invention aims to solve is to enable logging with reliable direction control and safety, even in steep terrain, using inexpensive equipment, without workers having to enter dangerous areas. The means to solve the problem involves using a drone to set up a wire saw and towing device, and operating it from a power source anchored at a remote location. Specifically, it combines a mechanism that cuts horizontally via a pulley installed at a low position with a mechanism that tows and fells the tree from a high position. The effect of the invention is that while ensuring worker safety, appropriate direction control using the pulley prevents the blade from getting stuck and prevents the tree from falling in an unexpected direction. [Brief explanation of the drawing] [Figure 1] This is an overall diagram showing the cutting mechanism of the present invention.

Claims

1. A remotely operated tree felling system comprising: a flexible wire saw member having a cutting blade; an aircraft (drone) for circling the wire saw member around a target tree; a first powered traction device installed at a safe location away from the tree for towing the wire saw member to perform cutting; and anchoring means for connecting and fixing the first powered traction device to the ground, a tree, or a fixed object such as heavy machinery so that it does not move due to the reaction force during traction.

2. A remotely operated tree felling system according to claim 1, wherein a pulley member for controlling the pulling direction is provided between the first power traction device and the wire saw member, and the pulley member is installed at approximately the same height as the wire saw member on a standing tree other than the target to be felled, thereby applying a horizontal cutting force to the tree to be felled.

3. A remotely operated tree felling system according to claim 1 or 2, comprising: a wire rope for controlling the direction of falling connected to a position higher than the center of gravity of the standing tree; a second power traction device for pulling the wire rope; and anchor means for connecting and fixing the second power traction device to a fixed object, characterized in that the tree is felled in a reliable direction by performing traction from above in parallel with the cutting operation.
