Description

Technical Field

[0001] The utility model relates to the technical field of agricultural planting, in particular to a pruning tool for watermelon side branches. Background Art

[0002] During the watermelon planting process, in order to ensure that nutrients are concentratedly supplied to the main vine growth and fruit development, the side branches of the plant need to be pruned in time. This is one of the key management links to improve watermelon yield and quality.

[0003] At present, the pruning of watermelon side branches mainly relies on manual work. Planters need to bend over or squat in the field first, and find and identify the side branches to be pruned one by one. After finding the target side branch, they need to hold the side branch with one hand to fix the position, and hold ordinary scissors or pruning shears with the other hand to cut the base of the side branch.

[0004] However, this traditional manual pruning method has its shortcomings. Since watermelons are mostly grown in the open field or in greenhouses, the plants grow to a low height. Planters need to bend and squat frequently during the operation. Long-term work can easily lead to fatigue of the waist and legs, high labor intensity, and low work efficiency, which is difficult to meet the needs of large-scale planting. In addition, when using some existing pruning tools, due to the dense growth of side branches of watermelon plants, some non-target side branches will be on the cutting surface of the tool during the shearing operation, and they are easily damaged by mistake, affecting the normal growth of the plant, further reducing the quality and efficiency of the pruning operation. Summary of the Invention

[0005] In view of the deficiencies in the prior art, the utility model provides a pruning tool for watermelon side branches.

[0006] In order to achieve the above purpose, the technical solution of the utility model is as follows:

[0007] A pruning tool for watermelon side branches, comprising a hollow stem;

[0008] The sorting plate is provided at the bottom end of the rod body, and an inner bevel is provided on the inner side of the top of the sorting plate, and a through groove is provided on one side of the inner bevel to form a side branch limiting area. An outer bevel is provided on the outer side of the top of the sorting plate to form a slideway for the side branches to enter the limiting area. The outer bevel, the inner bevel and the through groove are all provided with an accommodating groove;

[0009] The slide rod is slidably arranged in the rod body, and its bottom end extends into the receiving groove and is provided with a lower cutter, the front end of the lower cutter is provided with a bent portion, and the lower cutter and the top of the bent portion are jointly provided with a lower cutting edge, and the outer side of the bent portion is provided with an extrusion surface;

[0010] When the slide rod drives the lower cutter to move upward, the lower cutting edge hooks the side branches in the limiting area and shears them, and the extrusion surface moves upward to form a pushing structure for the remaining side branches on the slide.

[0011] Preferably, one side wall of the through groove is continuous with the inclined surface of the accommodating groove, and the angle between the two is 30° to 60°, so that when the lower cutting edge hooks the side branch and moves upward, the side branch moves along the side wall of the through groove away from the outer inclined surface.

[0012] Preferably, the bottom end of the outer inclined surface is continuous with the bottom surface of the sorting plate to form a pointed structure.

[0013] Preferably, a spring is elastically connected between the top inner wall of the rod body and the top end of the slide rod, and the spring ensures that the lower cutter is always located in the accommodating groove in a natural state.

[0014] Preferably, an upper cutting knife is provided at the bottom end of the slide rod, a through opening is provided at the bottom of the upper cutting knife, and the bottom surface of the through opening forms an upper cutting edge that cooperates with the lower cutting edge for shearing.

[0015] Preferably, a push pad is provided on one side of the sorting plate, and the push pad is made of rubber and has rough stripes on its surface.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: the side branch slide and the limiting area formed by the outer bevel, inner bevel and through groove arranged on the sorting plate can facilitate the entry of watermelon side branches and achieve the sorting effect; in addition, when the lower cutter hooks the side branch to be cut and moves upward, the side branch will move away from the outer bevel along the side wall of the through groove and keep a distance from the remaining side branches; at the same time, the upward movement of the extrusion surface of the bent part of the lower cutter can push the remaining side branches on the slide, reduce interference, achieve physical isolation, solve the problem of easy mis-cutting in traditional operations, improve the accuracy and efficiency of pruning, and reduce plant damage.

[0023] It is easy to understand that according to the technical solution of the present invention, without changing the essential spirit of the present invention, a person skilled in the art can propose a variety of interchangeable structural methods and implementation methods. Therefore, the following specific embodiments and drawings are only illustrative of the technical solution of the present invention and should not be regarded as the entire present invention or as a limitation or restriction of the technical solution of the present invention. Example

[0024] like Figures 1-4 As shown, the pruning tool for watermelon side branches includes an internal axially hollow rod body 1, which has a certain length and is convenient for users to hold. The watermelon side branches can be cut without bending over or squatting.

[0025] The sorting plate 2 is arranged at the bottom end of the rod body 1, and an inner bevel 22 is provided on the inner side of the top thereof, and a through groove 23 is provided on one side of the inner bevel 22 to form a side branch limiting area. An outer bevel 21 is provided on the outer side of the top of the sorting plate 2, and the bottom end of the outer bevel 21 is continuous with the bottom surface of the sorting plate 2 to form a pointed structure, which facilitates the insertion of the device between the side branches and makes it easier to contact the side branches to be processed; a slide channel is formed for the side branches to enter the limiting area, and an accommodating groove 24 is provided on the outer bevel 21, the inner bevel 22 and the through groove 23.

[0026] The sliding rod 3 is slidably arranged in the rod body 1, and its bottom end extends into the accommodating groove 24 and is provided with a lower cutting knife 31. The front end of the lower cutting knife 31 is provided with a bending portion 32, and the top of the lower cutting knife 31 and the bending portion 32 are jointly provided with a lower cutting edge 33. The design of the bending portion 32 helps to stably hook the side branches and improve the reliability of shearing; the outer side of the bending portion 32 is provided with an extrusion surface 34. When the extrusion surface 34 moves upward, it can push the remaining side branches on the slide to prevent these side branches from interfering with the side branches to be cut, ensuring that the shearing target is clear.

[0027] A spring 35 is elastically connected between the top inner wall of the rod body 1 and the top of the slide rod 3, and the spring 35 ensures that the lower cutter 31 is always located in the accommodating groove 24 in a natural state; thereby providing a guarantee for the initial state of the shearing action, ensuring that the various components of the device are accurately positioned when not in use, and preparing for subsequent shearing operations.

[0028] An upper cutter 4 is provided at the bottom end of the slide bar 3. A through opening 41 is provided at the bottom of the upper cutter 4, and the bottom surface of the through opening 41 forms an upper cutting edge that cooperates with the lower cutting edge 33 for shearing.

[0029] When the slide bar 3 drives the lower cutter 31 to move upward, the lower cutting edge 33 hooks the side branches in the limit area and cuts them, and the extrusion surface 34 moves upward to form a pushing structure for the remaining side branches on the slide;

[0030] One side wall of the through groove 23 is continuous with the inclined surface of the accommodating groove 24, and the angle between the two is 30° to 60°, so that when the lower cutting edge 33 hooks the side branch and moves upward, the side branch moves along the side wall of the through groove 23 in the direction away from the outer inclined surface 21; thereby, the side branch to be cut is separated from the other side branches, further preventing the other side branches from interfering with the side branch to be cut, and preventing the effect of accidental cutting.

[0031] A push pad 5 is provided on one side of the sorting plate 2. The push pad 5 is made of rubber and has rough stripes on the surface. It is used to push the watermelon side branches to move, so as to prevent the watermelon side branches on the other side of the outer inclined surface 21 from interfering with the watermelon side branches to be cut, thereby enhancing the combing and isolation capabilities of the side branches.

[0032] Working Principle: In its natural state, the spring 35 is in a relaxed state, and the slide bar 3, under the action of the spring 35, positions the lower cutter 31 within the receiving groove 24. During use, the tip structure of the sorting plate 2 is inserted between the watermelon branches, and the branches enter the branch limiting zone along the slide formed by the outer inclined surface 21. Then, the top of the slide bar 3 is pressed, and the slide bar 3 overcomes the elastic force of the spring 35 and moves upward, driving the lower cutter 31 upward and hooking the branch to be cut in the limiting zone. As the slide bar 3 continues to move upward, the lower cutting edge 33 cooperates with the upper cutting edge of the upper cutter 4 to complete the cutting of the branch. At the same time, the extrusion surface 34 of the bent portion 32 moves upward, pushing the remaining branches on the slide to prevent them from interfering with the cutting process. In addition, due to the angle between the side wall of the through groove 23 and the inclined surface of the receiving groove 24, the branch to be cut moves along the side wall of the through groove 23 away from the outer inclined surface 21 when it is hooked and moved upward, further separating it from the remaining branches. After the cutting is completed, the slide bar 3 is released. Under the elastic force of the spring 35, the slide bar 3 drives the lower cutter 31 to return to the receiving groove 24 and wait for the next operation.

[0033] The technical scope of the present invention is not limited to the contents described above. Those skilled in the art can make various deformations and modifications to the above embodiments without departing from the technical concept of the present invention, and these deformations and modifications should all fall within the scope of protection of the present invention.
