Abstract

A novel fruit tree girdling device comprises a main body frame handle, a main body frame, a main body frame left arm, a first pin shaft, a first plastic idler wheel, a second pin shaft, a second plastic idler wheel, a reversed-U-shaped girdling cutter, a reversed-U-shaped girdling cutting edge, a screw, a screw hole, an extension arm, a torsion spring, a third pin shaft and a main body frame right arm. The main body frame handle is arranged at one end of the main body frame, and the first plastic idler wheel and the second plastic idler wheel are respectively arranged on the main body frame left arm through the first pin shaft and the second pin shaft to enable the girdling device to rotate around fruit trees smoothly. The extension arm is arranged on the main body frame right arm through the third pin shaft. The torsion spring is arranged on the third pin shaft, the two ends of the torsion spring are respectively fixed to the main body frame right arm and the extension arm, and accordingly the girdling device can be tightly attached to trunks of the fruit trees in the torsion action of the torsion spring. The reversed-U-shaped cutter is fixed to the extension arm through the screw, and the cutting edge of the girdling cutter can be inserted into barks of the trunks of the fruit trees in a work state.

Description

New fruit tree girdler

technical field

The utility model belongs to the field of agricultural machinery and tools, in particular to a novel fruit tree girdling device.

Background technique

Girdling of fruit trees is one of the effective measures to avoid nutrient loss of fruit trees and improve fruit quality and yield. At present, the fruit tree girdling method that people generally adopt is to cut two annular cuts on the fruit tree trunk with a common sickle, and then the trunk epidermis in the middle of the two annular cuts is removed with a flat shovel. This method not only has high labor intensity and low efficiency, but also is difficult for the operator to grasp the depth of the incision, and it is very easy to cut off the woody part of the fruit tree, resulting in phenomena such as difficult healing of the girdling mouth and damage to the tree by dead branches.

Contents of the invention

Aiming at the various deficiencies of the above-mentioned fruit tree girdling method, the utility model proposes a new type of fruit tree girdling device which is efficient, safe, labor-saving and labor-saving.

The technical scheme of the utility model: a new type of fruit tree girdling device, including the handle of the main body frame, the main body frame, the left arm of the main body frame, the pin shaft I, the plastic roller I, the pin shaft II, the plastic roller II, and the inverted U-shaped girdling knife , Inverted U-shaped girdling blade, screw, screw hole, extension arm, torsion spring, pin shaft III, right arm of the main frame. The handle of the main frame is installed on one end of the main frame, and the two plastic rollers Ⅰ and Ⅱ are respectively installed on the left arm of the main frame through pin shafts Ⅰ and Ⅱ, so that the ring stripper can rotate around the fruit tree more smoothly. The extension arm is installed on the right arm of the main frame through the pin shaft III. The torsion spring is installed on the pin shaft III, and the two ends are respectively fixed on the right arm of the main frame and the extension arm, so that the girdling device is close to the trunk of the fruit tree under the torsion force of the torsion spring. The inverted U-shaped girdling knife is fixed on the extension arm by screws, and the blade of the girdling knife is inserted into the epidermis of the fruit tree trunk in a working state.

The beneficial effects of the utility model are: the upper extension arm of the girdling device can be opened at any angle, which is suitable for girdling of fruit trees with different diameters, and the sharp blade of the inverted U-shaped girdling knife can easily girdling the fruit trees, And the stripped tree trunk skin can flow out smoothly from the girdler, the shape is light and handy, and it is easy to use.

Detailed ways

When working, the operator holds the handle (1) of the main frame with one hand, overcomes the torsion force of the torsion spring (13) with the other hand, opens the extension arm (12) clockwise, and puts the girdling device on the girdling part of the fruit tree trunk (16) , Make the plastic roller I (5) and the plastic roller II (7) close to the fruit tree trunk (16). Then, the operator unclamps the extension arm (12), so that the inverted U-shaped girdling knife (8) is also close to the fruit tree trunk (16) under the torsion force of the torsion spring (13), and then gently presses the extension arm (12) by hand. The inverted U-shaped girdling knife (8) on the top makes the inverted U-shaped girdling blade (9) inserted in the fruit tree trunk (16) epidermis. Finally, the operator turns the main body frame (2) firmly through the main body frame handle (1), and the sharp inverted U-shaped girdling blade (9) will peel off the epidermis ring of the fruit tree trunk (16), and the peeled off trunk epidermis Flows smoothly from the inverted U-shaped girdling knife (8).
