Embodiment Construction

[0010] The invention provides a standing tree directional felling device. The present invention will be further described below in conjunction with the accompanying drawings.

[0011] Such as figure 1 , 2 , Shown in 3,4, the structure of device of the present invention and operation process are:

[0012] The left chassis 1 and the right chassis 7 are placed around the tree, the two are fixed together by six identical pins 3 and connecting plates 4, and the tree is located in the big round hole in the middle. Press the manual oil pump 12 by hand to press the oil in the oil tank 11 into the fixed hydraulic cylinders 5, 8, 9, positioning hydraulic cylinders 6 and 10 and push tree hydraulic cylinder 2 through the oil pipes. The piston rod of cylinder 5,8,9 stretches out, buttresses the bottom of the trunk, so that the whole device is fixed together with the bottom of the trunk. The piston rods of positioning hydraulic cylinders 6 and 10 are pressed against the trunk under the ...

Abstract

The invention discloses a standing tree orientated felling device. A left base plate and a right base plate are fixed together through six identical pins and a connecting plate, three fixing hydraulic cylinders, two locating hydraulic cylinders and a tree pushing hydraulic cylinder are mounted on the base plates respectively, and a chain saw, an electric cylinder, an oil tank and a manual oil pump are further fixed to a base, the piston rods of the three fixing hydraulic cylinders stretch to push against the bottom of a tree trunk, the base and the tree trunk are fixed, the electric cylinder drives the chain saw to rotate, the tree trunk is sawn off through the chain saw in the rotating process, the locating hydraulic cylinders prevent the tree trunk from falling to two sides, and a standing tree falls in a fixed direction under the pushing of the piston rods in the tree pushing hydraulic cylinder. The standing tree orientated felling device can be suitable for standing trees of different diameters, improve production efficiency, save manpower and reduce cost.

Description

technical field [0001] The invention belongs to the technical field of forestry machinery, and in particular relates to a standing tree directional felling device. Background technique [0002] The U.S. Bureau of Labor Statistics recently released a list of the top ten most dangerous occupations in the country. Loggers ranked first with a work-related death rate of 127.8 per 100,000. In determining how hazardous each job is, experts from the U.S. Bureau of Labor Statistics considered the number of fatal and nonfatal workplace injuries and the odds of occupational disease. By this measure, lumberjacking is the most dangerous occupation in the United States. According to statistics, there will be 92.4 work-related fatalities for every 100,000 forest workers, while the national average in the United States is only 4.1. At present, my country's current manual logging equipment is backward, labor-intensive, poor in safety, and low in efficiency. Contents of the invention [...
