Integral rotary drill bit and portable rotary drill and method for crushing tree stubble

Abstract

The rotary drill bit of the present invention comprises: a fixed point, a main cutting edge and a chip removal groove, the main cutting edge and the chip removal groove are evenly distributed on the conical surface, and a protruding fixed point is arranged on the cone point, which is integrally formed by high-speed tool steel, and utilizes The rotating fixed tip and main cutting edge drill the bush starting from the center of the bush down and towards the perimeter until the bush is completely pulverized. The integral rotary drill bit has high strength and rigidity and high drilling efficiency. The present invention also provides a portable rotary drilling machine, including: a hand support frame, a power device, a transmission rod and a rotary drilling head, which are detachably connected so that the portable rotary drilling machine can be disassembled into parts that are easy to carry, so as to be transported to complex forests. Strip, reassembled and crushed the stumps of diseased trees in situ. The present invention also provides a method for crushing tree stumps. Without having to dig out tree stumps, a portable rotary drilling machine is used to directly crush tree stumps in the soil on the spot, which can effectively control the epidemic of pine nematodes in a timely manner.

Description

Technical field [0001] The present invention belongs to the field of forestry machinery, and in particular to a monoclier-rotary drill bit and a portable rotary drilling machine and a tree pulverization method. Background technique [0002] Pine wood nematodes are entered into the wooden part through the pine brown cymbers, and they are parasitic in the resin. At the same time of mass reproduction, it gradually spreads throughout, and causes damage and death of resin thin-walled cells and epithelial cells, resulting in water, and finally dead. Pine trees infected by Pinemar Pine is the object of laminate. In the following year, the loose brown day will carry a large number of nemates and inoculate to "Jianshu", so that the loop is caused by the spread of the nematodes of the pine. [0003] Lin Land cleaning, cutting and burning the trees and dying trees, removing the diseased plant residues, which is a more reliable control, to cut off the spread of pose nematodes, to achieve the...

AI Technical Summary

Problems solved by technology

However, the volume and quality of large-scale machinery are too large, it is difficult to enter the complex areas of the forest, and it cannot crush tree stumps anytime and anywhere, and cannot effectively control the epidemic of pine nematodes in a timely manner.

[0005] At present, there is no small machine in China that can crush tree stumps without digging out the whole tree stumps. It is impossible to crush diseased tree stumps anytime and anywhere, and it is difficult to control the epidemic of pine nematodes.
