Description

Technical Field

[0001] This utility model belongs to the field of fruit tree planting technology, specifically referring to a fruit tree girdling device. Background Technology

[0002] A fruit tree girder is a tool specifically designed for fruit tree management, primarily used for girdling or girdling fruit trees. Its core function is to temporarily block the transport of nutrients produced by photosynthesis to the roots by cutting the bark at the base of the trunk or main branches (down to the phloem, without damaging the xylem), thereby adjusting the nutrient distribution of the fruit tree and promoting flower bud differentiation and fruit growth.

[0003] Currently, fruit tree girders are mainly divided into the following types according to their design and function: single-sided girder, double-sided girder, girder shears, girder pliers, multi-functional girder, quick girder shears, etc. Regardless of the type of girder, when using it, it cuts directly through the bark of the fruit and vegetables. This method of use can easily damage the blade, and the bark of some fruit trees is relatively hard. If the blade does not cut into the bark, the blade may also scatter, which can be dangerous.

[0004] In addition, because each fruit tree grows at a different rate, when performing girdling on the same orchard, the girdling device is easy to use on small-diameter fruit trees but difficult on large-diameter fruit trees, which is very laborious. Utility Model Content

[0005] The present invention aims to at least solve the problem that the blade of the girder may break and splatter when it comes into direct contact with the fruit tree, and the problem that the girder is more laborious when girdling large-diameter fruit trees.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: This utility model proposes a fruit tree girder, comprising two sets of cross-hinged girder frames, one end of which is an arc-shaped end, and further comprising:

[0007] Sliding support assembly: located at the hinge position of the two sets of ring cutting frames, consisting of a support frame with an opening on one side and several rotating shafts, wherein the rotating shafts rotate on the opening side of the support frame and are close to the arc-shaped end of the ring cutting frame;

[0008] Lever arm extension: Hinged to the handle extending from the other end of the ring-cutting frame;

[0009] Pre-cutting blade: It extends from the inner side of the arc-shaped end of a set of ring-cutting frames. When ring-cutting the trunk of a fruit tree, the pre-cutting blade makes a cutting mark on the trunk in advance.

[0010] Fruit tree girdling knife: mounted on the end of another set of girdling frames away from the handle, and used in conjunction with the pre-cutting knife to girdle the bark of the fruit tree.

[0011] Furthermore, the other set of the girdling frame has a gap at its end, and the girdling frame also has a through hole and a waist hole passing through the gap. The fruit tree girdling knife is installed at the through hole and the waist hole respectively by two sets of screws.

[0012] Furthermore, the fruit tree girdling knife includes an inclined blade at the front end, a connecting seat at the end, and a transition slide in the middle. The connecting seat is connected to the through hole and the waist hole by a screw. The transition slide is inclined, and the blade cuts off the bark along the mark left by the pre-cutting knife.

[0013] Furthermore, the open end of the support frame is arc-shaped and rotates on the ring cutting frame via a pin. The rotating shaft is arranged along the arc-shaped edge of the open end, and the spatial position of the rotating shaft is between the cutting edge and the pre-cutting blade.

[0014] Furthermore, the outer side of the grip is provided with an arc-shaped groove that cooperates with the fingers to grip, and a hinge seat extends from the grip to connect with the lever arm extension member.

[0015] Furthermore, the lever arm extension is configured as a rod-shaped structure, with one end hinged to the hinge seat and an inner gripping groove that mates with the arc-shaped groove. The other side of the lever arm extension is provided with a wavy groove.

[0016] Furthermore, the width of the blade is equal to the distance between the two sets of pre-cutting blades and is horizontally symmetrical.

[0017] The beneficial effects of this utility model by adopting the above structure are as follows:

[0018] 1. Pre-cutting blades are installed on both sides of the girdling frame to pre-cut two marks on the fruits and vegetables to be girdled, so that the bark can be quickly peeled off by the girdling blade during the girdling process, reducing the number of times the girdling blade is damaged.

[0019] 2. By adding a lever arm extension to the end of the handle, the lever arm extension can be extended when the ring cutting operation becomes difficult, thereby increasing the force during the ring cutting operation and reducing the difficulty of the ring cutting operation;

[0020] 3. By utilizing the sliding support component, which fits snugly against the fruit tree, a stable girdling effect is achieved. At the same time, the special design of the fruit and vegetable girdling knife facilitates the removal of the cut peel from the transition slide. Attached Figure Description

Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1 , Figure 4 and Figure 5 :

[0029] The fruit tree girder includes two sets of cross-hinged girder frames 1, one end of which is an arc-shaped end 11. It also includes: a sliding support assembly 2, located at the hinge position of the two sets of girder frames 1, consisting of a support frame 21 with an opening on one side and several rotating shafts 22. The rotating shafts 22 rotate on the opening side of the support frame 21 and are close to the arc-shaped end 11 of the girder frame 1. The opening end of the support frame 21 is arc-shaped and rotates on the girder frame 1 via a pin. The rotating shafts 22 are positioned along the arc-shaped edge of the opening end; and a lever arm extension 3, hinged to a handle 12 extending from the other end of the girder frame 1. The pre-cutting blade 13 extends from the inner side of the arc-shaped end 11 of a set of girdling frames 1. When girdling the trunk of a fruit tree, the pre-cutting blade 13 makes a cutting mark on the trunk in advance. The end of the other set of girdling frames 1 is provided with a gap 14. The fruit tree girdling blade 4 is installed at the end of the other set of girdling frames 1 away from the handle 12. It works with the pre-cutting blade 13 to girdle the bark of the fruit tree. The other set of girdling frames 1 also has a through hole 15 and a waist hole 16 that pass through the gap 14. The fruit tree girdling blade 4 is installed in the through hole 15 and the waist hole 16 respectively by two sets of screws.

[0030] When using the device, place the trunk of the fruit tree to be girdled between the two sets of girdling frames 1, hold the handle 12, and under the hinge action, the two sets of girdling frames 1 approach each other and clamp the outer edge of the trunk's circumference. At this time, the pre-cutting blade 13 and the fruit tree girdling blade 4 also come into contact with the trunk. By clamping the handle 12 and applying force, the pre-cutting blade 13 cuts into the trunk to a certain depth, the depth of which is controlled by the gripping force. Then, rotate the girdling frame 1 along the fruit tree. At this time, the pre-cutting blade 13 cuts two marks on the fruit tree, and the fruit tree girdling blade 4 peels off the bark between the two marks along the marks.

[0031] Please see Figure 1 , Figure 4 and Figure 5 :

[0032] The fruit tree girdling knife 4 includes an inclined blade 41 at the front end, a connecting seat 42 at the end, and a transition slide 43 in the middle. The width of the blade 41 is equal to the distance between the two sets of pre-cutting knives 13 and is horizontally symmetrical. The spatial position of the rotating shaft 22 is between the blade 41 and the pre-cutting knives 13. The connecting seat 42 is connected to the through hole 15 and the waist hole 16 through a screw. The transition slide 43 is inclined. The blade 41 cuts off the bark along the traces left by the pre-cutting knives 13. The blade 41 cuts into the trunk and gets stuck between the two sets of traces cut by the pre-cutting knives 13. As the girdling frame 1 rotates, the bark on the trunk is peeled off. The bark slides along the transition slide 43 and is finally discharged from the gap 14.

[0033] Please see Figure 1 , Figure 4 and Figure 5 :

[0034] The outer side of the grip 12 is provided with an arc-shaped groove 121 that cooperates with the fingers to grip. The grip 12 also extends a hinge seat 122 that is connected to the lever arm extension 3. The lever arm extension 3 is a rod-shaped structure, one end of which is hinged to the hinge seat 122, and the inner side is provided with a grip groove 31 that cooperates with the arc-shaped groove 121. The other side of the lever arm extension 3 is provided with a wave-shaped groove 32.

[0035] When the diameter of the fruit tree trunk being peeled is large, the lever arm extension 3 can be removed by rotating it and fixed with screws to extend the length of the handle 12. The increased lever arm makes it easier to peel the bark of large-diameter fruit tree trunks.

[0036] It should be noted that the diameter of the fruit tree trunk is limited by the girdling frame 1. If it is necessary to cut a fruit tree trunk with an extra-large diameter, a girdling frame 1 with a larger diameter arc end 11 needs to be ordered to achieve the peeling.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.

[0038] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
