An industrial logging knife that can be opened and closed

Abstract

The invention discloses an openable and closable industrial wood chopper, which comprises a chopper surface, a chopper pushbutton, a chopper surface hinge, a blade, free bearings, four opening and closing plates, an opening and closing handle, a chopper handle, an anti-skid grip, movable arms, a center shaft, screws, springs, connectors, trunnions, a thread, load support frames and a fixed plate, wherein one end of the chopper surface is connected with the chopper surface hinge which is connected with the blade, and the other end of the chopper surface is connected with the free bearings; the free bearings are connected with one end of each opening and closing plate; the fixed plate is arranged in a part formed by the four opening and closing plates, and is connected with one end of each spring; the other ends of the springs are connected with the movable arms; one end of each movable arm is connected with the corresponding connector; the connectors are connected with the center shaft through the screws; the other ends of the movable arms are connected with the trunnions which are connected with the load support frames. The openable and closable industrial wood chopper can be operated by a single person with low labor consumption, and energy resource waste and natural environment damage caused by use of a large-scale machine for woodchopping are avoided.

Description

technical field [0001] The invention relates to an industrial logging tool, in particular to an openable and closable industrial logging knife, which belongs to the field of industrial products. Background technique [0002] The first step in an industrial logging operation. Also known as felling trees and releasing trees. Generally, on the designated felling area, first determine the felling direction of the standing tree, clear the obstacles around it, open up a safety road, and then fall the standing tree. There are two types of logging: manual logging and mechanical logging. When felling with a hand saw or a chain saw, two parallel or triangular saws, namely the lower saws, are sawed out at the root of the trunk on one side of the felling direction. The opening angle is generally 30°-35°, and the depth is generally 1 / 5-1 / 3 of the trunk diameter. Then use an ax or a saw to remove the wood chips between the two saw cuts. You can also use a saw to cut a horizontal kerf...

Problems solved by technology

Existing industrial logging tools are generally divided into simple tools and large-scale equipment, but large-scale equipment generally consumes a lot of energy, pollutes a lot, and causes great damage, but small-scale logging tools such as knives and axes require manpower to supply. Generally, it is difficult to cut down large trees easily, but the existing logging tools are difficult to overcome the above problems
