Portable electric fruit tree girdling machine and method

Abstract

The invention relates to a portable electric fruit tree girdling machine and a method. The portable electric fruit tree girdling machine comprises a machine body, a power system, a transmission system and a tool bit, a battery and a direct-current motor are adopted in the power system, power is output to the tool bit through the transmission system, and the tool bit comprises a limiting block, a saw rack and saw blades. The limiting block is arranged on the front side of the saw rack, the upper portion of the limiting block is movably connected to the front side of the machine body, the lower portion of the limiting block is arranged between the two saw blades, and the outer side of the saw blade is of an arc-shaped structure. The portable electric fruit tree girdling machine has the advantages that the asymmetric sawtooth saw blades are adopted, the smoothness of a cut surface can be guaranteed to meet the technical requirement of girdling, wood bits can be discharged fast, and it is guaranteed that work is fast and smooth; the saw blades are always kept at the optimum cutting position by means of the limiting block designed in the middle, bark is cut off, and it is avoided that the xylem is damaged to influence normal growth of fruit trees; in addition, the problems that a traditional girdling tool is low in efficiency, wastes time and labor, and is irregular in girdling opening are solved.

Description

technical field [0001] The invention relates to a forest fruit cultivation operation machine and method, in particular to a portable electric fruit tree girdling machine and method. Background technique [0002] Girdling, also known as girdling, is a commonly used technique in horticulture and gardening. It is suitable for some fruit trees and flowers that grow particularly vigorously. The principle is to artificially cut off and peel off a section of bark to temporarily cut off the channel for the downward transport of tree nutrients. , so that nutrients can be concentrated for a period of time to supply flowering and fruit setting. The requirement is to only peel off the cortex and not to damage the xylem, otherwise it will affect the annual growth of the tree. The existing girdling work generally adopts grafting knife or girdling knife, which is very troublesome to operate, time-consuming and laborious, and has many shortcomings: (1) it is necessary to cut twice around th...

AI Technical Summary

Problems solved by technology

The existing girdling work generally adopts grafting knife or girdling knife, which is very troublesome to operate, time-consuming and laborious, and has many shortcomings: (1) it is necessary to cut twice around the branch with a knife, that is, to rotate two 360 degrees, and then The width of the girdling opening is not easy to grasp when the skin is peeled off; (2) the force is not uniform, and the depth of the knife edge is difficult to grasp, which often hurts the wood; (3) the cutting position is difficult to grasp on a plane, and the cutting edge is not easy to align (4) When the branches are dense, it is more inconvenient to operate; (5) Manual operation is time-consuming and labor-intensive, and the work is hard

[0003] At present, there are some studies on girdling equipment at home and abroad, such as double-blade roller girdling knife, four-blade fixed inline girdling knife, etc., all of which are manually operated, and only one case of girdling equipment using mechanical power has been reported, but other It is a large-scale mechanical equipment with poor operational flexibility and is not suitable for forestry operations. Its safety has yet to be verified. The technical difficulty of mechanical girdling lies in the use of manual or mechanical power tools to quickly peel off a certain width of fruit tree bark without damaging it. and its xylem
