Embodiment Construction

[0014] The clamping handle (1) opens the C-shaped clamping mouth (3) through the hinge (2), and uses the principle of leverage to transfer the force to the blade with the rolling bearing (4) as the fulcrum, and rotate clockwise to easily peel off the jujube bark , the stripped bark is discharged along the miscellaneous hole (6); when the jujube tree is girdled, the rolling bearing (4) rotates around the jujube trunk to reduce the friction between the clamping mouth (3) and the jujube tree; The blade fastening hole (51) is fixed by a set screw, and the girdling depth can be adjusted by adjusting the relative position of the girdling blade fastening hole (51) and the set screw. The blade edge (52) adopts an arc transition, It is suitable for cutting into the bark at different angles without damaging the subcutaneous tissue, and the blade is easy to replace after it is worn out, and the cut bark of the jujube tree is discharged through the miscellaneous discharge hole (6).

Abstract

The invention relates to a jujube tree girdling machine, and particularly relates to a simple hand-held jujube tree girdling machine. The jujube tree girdling machine comprises a girdling handle, a hinged rivet, C-shaped clamping openings, rolling bearings and girdling blades. The C-shaped clamping openings are welded with the girdling handle, and the sizes of the two C-shaped clamping openings are adjusted by the handle, so that jujube trees with different diameters can be girdled. Each C-shaped clamping opening is provided with one rolling bearing, one girdling blade and a discharging hole.The girdling handle transmits force to the blades on the C-shaped clamping openings by utilizing the lever principle, the blade peels down the bark of a jujube tree, and the peeled jujube tree bark isdischarged through the discharging holes. When the jujube tree is girdled, the rolling bearings rotate around the tree trunk of the jujube tree, so that the friction force between the C-shaped clamping openings and the jujube tree is reduced; the cutting depth of the cutters can be changed through the regulation of set screws on the cutter set holes; and the arc cutting edge of each blade is adopted for transition, so that the bark cutting at different angles can be adapted, and the subcutaneous tissues are not scratched.

Description

technical field [0001] This patent relates to a jujube tree girdling knife, in particular to a simple hand-held jujube tree girdling knife. Background technique [0002] Jujube tree is a multi-flowered tree species, but the natural fruit setting rate is very low. In the past, "flail tree" (also called girdling or girdling) and "shaved tree" measures were important means to promote fruit setting, especially girdling was used more However, in most areas of our country, the girdling is carried out manually with a bent sickle one by one, which is time-consuming, laborious and extremely inefficient. In addition, the bark outside the jujube tree is very hard, which requires a lot of manual work. It requires another hand to press the sickle, which reduces the efficiency, and the transfer of labor to the city is also increasing. Therefore, there is an urgent need for a simple and light jujube girdling knife to replace the bent sickle for girdling. [0003] With the development of m...
