Description

Technical Field

[0001] This utility model belongs to the technical field of fruit tree girdling and bark removal knives, and particularly relates to a multifunctional girdling and bark removal knife for fruit tree trunks. Background Technology

[0002] A girdling knife is a horticultural tool primarily used for girdling and barking fruit trees. Girdling involves making one or more ring cuts around the base of a large branch or lateral branch with a sharp knife at a smooth surface. This is mainly used to promote flowering and fruit retention in young, overly vigorous fruit-bearing trees that are not flowering at the appropriate age. Barking involves making two ring cuts around the trunk or main branch of a fruit tree, spaced 3-5 mm apart, and removing the bark. This is mainly used for vigorous fruit tree varieties with high regeneration capacity, such as pomelos and oranges.

[0003] Existing multi-functional girdling and bark stripping knives for fruit tree trunks often only have one layer of girdling and bark stripping structure. Therefore, when performing girdling, it is often necessary to perform at least two girdling cuts on the trunk or main branches according to the girdling interval in order to peel off the bark, which is time-consuming and laborious. Utility Model Content

[0004] This invention provides a multifunctional girdling and bark stripping knife for fruit tree trunks, aiming to solve the problem mentioned in the background art that existing fruit tree girdling and bark stripping knives often have only one girdling and bark stripping structure and require at least two girdlings to peel off the bark.

[0021] This utility model embodiment provides a multifunctional girdling and girdling knife for fruit tree trunks, such as... Figure 1-4 As shown, the multifunctional girdling and girdling knife for fruit tree trunks includes: a U-shaped plate 1; a horizontal shaft 2 rotatably mounted on the inner wall of the U-shaped plate 1; a rotating plate 3 fixedly sleeved on the horizontal shaft 2; an arc-shaped clamping plate 4 fixedly mounted on the rotating plate 3; a girdling blade 5 mounted on the inner wall of the arc-shaped clamping plate 4; an opening and closing mechanism mounted on the inner wall of the U-shaped plate 1, the opening and closing mechanism being used to control the opening and closing of the arc-shaped clamping plate 4; and a girdling spacing adjustment mechanism located at the bottom of the U-shaped plate 1, the girdling spacing adjustment mechanism being used to adjust the girdling spacing.

[0022] In this embodiment, a U-shaped plate 1 is included as the main structure. A horizontal shaft 2 is rotatably mounted on its inner wall. A rotating plate 3 is fixedly sleeved on the horizontal shaft 2. An arc-shaped clamping plate 4 is fixedly mounted on the rotating plate 3. A ring-cutting blade 5 is mounted on the inner wall of the arc-shaped clamping plate 4 for ring-cutting the fruit tree trunk. An opening and closing mechanism is also installed on the inner wall of the U-shaped plate 1.
