Description

Technical Field

[0001] The utility model relates to the technical field of ring cutting knives, in particular to a ring cutting knife used for eucalyptus. Background Art

[0002] Eucalyptus girdling mainly refers to using a girdling tool to encircle the base of the eucalyptus trunk (20-30cm from the trunk) to peel off a certain width of bark, in order to destroy the conductive tissue at the base of the trunk, namely the phloem. After girdling the eucalyptus, on the one hand, a mechanical injury is formed, and the dormant buds below the wound become active; on the other hand, the water and minerals absorbed by the eucalyptus root system can be transported upward normally, but the downward transportation of organic matter is hindered, resulting in a large amount of organic matter accumulating at the upper end of the girdling incision. These organic substances promote the differentiation of the callus tissue formed at the wound into adventitious buds. These two factors promote the production of buds at the base of the trunk. Eucalyptus girdling to promote sprouting is one of the common asexual reproduction methods of eucalyptus. In order to facilitate girdling of eucalyptus, a girdling knife is often used.

[0003] The distance between the two sets of blades of the existing ring cutting knife is fixed, which makes it inconvenient to adjust the width of the outer ring cutting of the eucalyptus. In this case, the eucalyptus needs to be ring cut multiple times, which is inconvenient to operate and time-consuming.

[0004] To this end, the utility model provides a ring cutting knife for eucalyptus, which solves the above problem by adjusting the distance between two groups of ring cutting knife heads through two groups of movable support rods in a diamond structure. Utility Model Content

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Embodiment 1:

[0022] See also Figure 1-3 A ring cutting knife for eucalyptus, comprising a ring cutting plate 1, wherein the ring cutting plate 1 is provided with two groups, wherein the outer end of one group of ring cutting plates 1 is symmetrically fixedly connected with a support rod 2, and the other group of ring cutting plates 1 is slidably connected to the support rod 2, wherein the slidable group of ring cutting plates 1 can be freely adjusted according to the size of the eucalyptus, and the inside of the ring cutting plate 1 is provided with a ring cutting component 3, and the ring cutting component 3 includes a card groove symmetrically opened at the outer end of the ring cutting plate 1, and a connecting plate 301 is clamped inside the card groove, and a ring cutting cutter head 302 is fixedly connected to the outer end of the connecting plate 301, and a connecting plate 303 is fixedly connected to the bottom end of the connecting plate 301, and a rotating rod 304 is symmetrically rotatably connected to the inside of the connecting plate 303, and a stud 305 is rotatably connected to the outer end of the rotating rod 304, and a screw 306 is internally threadedly connected to the stud 305, and the screw 306 passes through the ring cutting plate 1 and is rotatably connected thereto. The purpose of this arrangement is that when girdling eucalyptus, first a group of girdling plates 1 fixed to the support rod 2 is clamped on the outer end of the eucalyptus, and the two groups of girdling heads 302 at the outer end of the girdling plates 1 are clamped into the bark of the eucalyptus, and then another group of girdling plates 1 are slid so that the two groups of girdling heads 302 at the outer end of the girdling plates 1 are clamped into the bark of the eucalyptus again. At this time, the girdling plates 1 are rotated to gird the outer end of the eucalyptus. The width of the girdling opening of the eucalyptus is the spacing between the two groups of girdling heads 302. Since the width of the girdling opening required for eucalyptus of different sizes is different, the screw rod 306 is rotated at this time to make the two groups of studs 305 at the outer end of the screw rod 306 move toward each other, so that the two groups of rotating rods 304 drive the connecting plate 301 to drive the girdling heads 302 to move, thereby adjusting the girdling width of the eucalyptus. The girdling of the eucalyptus can be completed at one time, and there is no need to gird the eucalyptus multiple times to increase its girdling width.

[0023] Preferably, the inner side of the ring cutting plate 1 is in an arc-shaped structure, the outer end of the screw rod 306 is provided with two sets of threads, the two sets of threads are arranged in opposite directions, and the two sets of rotating rods 304 are in a diamond-shaped structure. The purpose of this arrangement is that the two sets of threads arranged in opposite directions enable the stud 305 to move in opposite directions, and the spacing between the two sets of ring cutting heads 302 is easy to adjust.

[0024] In this embodiment, when in use, the screw rod 306 is rotated according to the ring cutting width required by the eucalyptus, so that the two groups of studs 305 at the outer ends of the screw rod 306 move toward each other, so that the rotating rod 304 rotating at the outer ends of the studs 305 are close to each other, thereby driving the ring cutting head 302 at the outer end of the connecting plate 301 to move toward the outer end of the ring cutting plate 1. After the spacing between the two groups of ring cutting heads 302 is adjusted, the two groups of ring cutting plates 1 are clamped on the outer ends of the eucalyptus, and then the ring cutting plate 1 is rotated to complete the ring cutting operation on the eucalyptus. The operation is simple and the ring cutting width is convenient to adjust.

[0025] Embodiment 2:

[0026] See also Figure 1-4 This embodiment provides a technical solution for a girdling knife for eucalyptus on the basis of the first embodiment: one end of the support rod 2 is provided with a thread, and the outer end of the support rod 2 is threadedly connected with a positioning column 4. The purpose of this arrangement is that the positioning column 4 can fix the distance between the two sets of girdling plates 1 to prevent the two sets of girdling plates 1 from loosening from the eucalyptus during the girdling process, thereby affecting the girdling effect.

[0027] Preferably, the front end of the ring cutting blade 302 is in the shape of a quadrangular pyramid, and the outer end of the ring cutting blade 302 is symmetrically provided with a guide groove 5, and the cross section of the guide groove 5 is in an arc shape. The purpose of this arrangement is that the guide groove 5 is provided so that the bark produced during the ring cutting process is discharged from the outer end of the ring cutting blade 302, thereby preventing the bark produced by cutting from affecting the ring cutting effect of the eucalyptus.

[0028] Preferably, the inner part of the ring cutting plate 1 is symmetrically rotatably connected with a guide wheel 6, and the length of the ring cutting cutter head 302 is greater than the radius of the guide wheel 6. The purpose of this arrangement is that the guide wheel 6 is arranged to facilitate the rotation of the two sets of ring cutting plates 1 at the outer end of the eucalyptus tree, and prevent the two sets of ring cutting plates 1 from getting stuck during the ring cutting process.

[0029] Preferably, the top of the ring cutting plate 1 is fixedly connected with a limit rod 8, which is rectangular and arranged in a slot at the top of the ring cutting plate 1, and the connecting plate 301 is slidably connected with the limit rod 8, and the outer end of the ring cutting plate 1 is fixedly connected with a handle 7. The purpose of this arrangement is that the limit rod 8 has a limiting effect on the sliding of the connecting plate 301, so that the ring cutting cutter head 302 moves vertically, and the ring cutting cutter head 302 is prevented from tilting during the adjustment process, thereby affecting the effect of eucalyptus ring cutting.

[0030] In this embodiment, when the two groups of ring cutting plates 1 are clamped from the outer end of the eucalyptus, the guide wheel 6 inside the ring cutting plate 1 contacts the eucalyptus, thereby facilitating the rotation of the two groups of ring cutting plates 1 and preventing the two groups of ring cutting plates 1 from getting stuck during the ring cutting process. During the ring cutting process, the bark is discharged from the guide groove 5 on the outside of the ring cutting head 302, avoiding the generated bark from affecting the ring cutting effect of the ring cutting head 302 at the outer end of the ring cutting plate 1.
