Description

Technical Field

[0001] The invention relates to the field of citrus, and in particular to a shaping and pruning device for planting citrus fruits. Background Art

[0002] A general term for citrus plants. The fruit is rich in nutrients and has a unique taste. In addition to being eaten fresh, canned food, juice, jam, wine, and candied fruit have become the main fruit processing products. The citric acid, essential oils, and pectin extracted from it can be used as raw materials for the food and pharmaceutical industries. Orange peels and orange piths are Chinese medicinal materials. The flowers can be smoked to make scented tea and extract essences, and are also a good source of nectar. Citrus trees are evergreen all year round, with beautiful tree postures, and can also be used for viewing.

[0003] At present, in the process of citrus fruit cultivation, it is necessary to regularly prune the branches of the fruits, so pruning knives are often used. Conventional pruning knives are mostly composed of two lever arms hinged to each other and blades connected to the ends of the lever arms. In actual application, when the two lever arms are close to each other to shear the branches, since the branches are mostly round, the pruning knives themselves are prone to slide outward during the shearing process, which can easily cause incomplete shearing. Therefore, we have made improvements on this and proposed a shaping and pruning device for citrus fruit cultivation. Summary of the invention

[0004] The object of the present invention is to provide a shaping and pruning device for planting citrus fruits. By providing an anti-skid unit, the problem that conventional pruning knives easily slip against branches during pruning, resulting in incomplete pruning, is solved.

[0005] In order to achieve the above-mentioned object of the invention, the present invention provides the following technical solutions:

[0006] A shaping and pruning device for planting citrus fruits, comprising a first grip arm and a second grip arm, wherein the first grip arm and the second grip arm are hinged to each other, and a reset structure is commonly connected between the first grip arm and the second grip arm, a shearing portion is fixed at the end of the first grip arm, and a limiting portion is provided at the end of the second grip arm, and the shearing portion is brought into contact with the limiting portion to form pruning by pressing the first grip arm and the second grip arm;

[0007] Wherein, an anti-skid unit is installed on the outer side of the limiting part, and the branch rod can be limited during pruning due to the action of the anti-skid unit.

[0008] As a preferred technical solution of the present application, the anti-slip unit includes a connecting shaft fixed to the outside of the shearing portion, a surface of the connecting shaft is sleeved with a limiting foot, and the end of the limiting foot is connected to a fixing piece for fixing the limiting foot.

[0009] As a preferred technical solution of the present application, the anti-slip unit further comprises a meshing ring arranged at the end of the limiting foot, and one side of the meshing ring is meshed with a gear movably connected to the surface of the shearing portion.

[0010] As a preferred technical solution of the present application, a motor is fixed on the surface of the gear, and a protective cover is fixed on the surface of the motor;

[0011] Wherein, the surface of the protective cover is fastened to the shearing portion by bolts.

[0012] As a preferred technical solution of the present application, an installation cavity is opened inside the connecting shaft, and a limit rod is slidably provided inside the installation cavity. Both sides of the surface of the limit rod are connected to springs fixed to the side walls of the connecting shaft. Under the action of the spring, the limit rod is naturally located inside the installation cavity.

[0013] As a preferred technical solution of the present application, there are multiple installation cavities, and the multiple installation cavities are annularly and equidistantly distributed on the surface of the connecting shaft;

[0014] A convex ball is fixed on the inner end of the limiting rod.

[0015] As a preferred technical solution of the present application, an assembly groove matching the connecting shaft is provided on the surface of the limit foot at a position corresponding to the connecting shaft, a threaded boss is formed at the edge of the assembly groove, and a threaded cover is threadedly connected to the surface of the threaded boss.

[0017] The connecting rod is located on the outer side of the buckle cover and is threadedly connected with a nut.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] In the scheme of this application:

[0020] 1. Through the cooperation of the shearing part and the limiting part, when pruning the branches of citrus fruits, the limiting feet can form a wrapped state on the other side of the pruning direction, so that a certain shearing space is formed by the limiting feet and the shearing part, so that the branches are located therein, thus ensuring the stability of the branches during the shearing process, so that the problem of slipping is not easy to occur, and ensuring the stability of the citrus fruits during pruning;

[0044] The anti-slip unit 3 includes a connecting shaft 31 fixed to the outside of the shearing portion 11, a limiting foot 32 is sleeved on the surface of the connecting shaft 31, and a fixing member 33 for fixing the limiting foot 32 is connected to the end of the limiting foot 32;

[0045] The anti-slip unit 3 further includes a meshing ring 34 disposed at the end of the limiting foot 32, and one side of the meshing ring 34 is meshed with a gear 35 movably connected to the surface of the shearing portion 11;

[0046] A motor 36 is fixed on the surface of the gear 35, and a protective cover 37 is fixed on the surface of the motor 36, wherein the surface of the protective cover 37 is fastened to the shearing portion 11 by a bolt 38, and a battery (not shown in the figure) may be provided on the surface of the first grip arm 1 and the second grip arm 2 for powering the motor 36. The anti-slip foot 37 can be disassembled by removing the bolt 38, thereby completing the disassembly of the motor 36 and meeting the subsequent replacement of the limit foot 32;

[0047] The connecting shaft 31 has an installation cavity 310 formed inside, and a limiting rod 311 is slidably provided inside the installation cavity 310. Both sides of the surface of the limiting rod 311 are connected to springs 312 fixed to the side walls of the connecting shaft 31. Under the action of the spring 312, the limiting rod 311 is naturally located inside the installation cavity 310.

[0048] There are multiple installation cavities 310, and the multiple installation cavities 310 are distributed in an annular manner and equidistantly on the surface of the connecting shaft 31;

[0049] A convex ball 313 is fixed to the inner end of the limiting rod 311;

[0050] A mounting groove 320 matching with the connecting shaft 31 is formed on the surface of the limiting foot 32, and a threaded boss 321 is formed at the edge of the mounting groove 320. A threaded cover 322 is threadedly connected to the surface of the threaded boss 321.

[0051] The fixing member 33 includes a connecting rod 330 fixed to the surface of the shearing portion 11, and a buckle cover 331 is slidably sleeved on the surface of the connecting rod 330. The buckle cover 331 can drive the convex ball 313 to drive the limiting rod 311 to extend out of the installation cavity 310.

[0052] The connecting rod 330 is located on the outer side of the buckle cover 331 and is threadedly connected with a nut 332;

[0053] In the actual application process, the first gripping arm 1 and the second gripping arm 2 are unfolded by the action of the reset structure 4, and the shearing portion 11 and the limiting portion 21 thereon are also synchronously unfolded to form a Figure 2 In the state shown, the limiting foot 32 in the anti-slip unit 3 is in the retracted state, that is, it does not overlap with the limiting portion 21, so that the expanded shearing portion 11 and the limiting portion 21 will not affect the pruning of citrus fruit branches;

[0054] When the opened cutting portion 11 and the limiting portion 21 are aligned with the branches of the citrus fruit, the motor 36 starts the gear 35 thereon to rotate, and the gear 35 drives the limiting foot 32 to flip by meshing with the limiting portion 21, forming a Figure 1 In the state shown, the limiting foot 32 and the shearing portion 11 together form a shearing space, through which the branches of citrus fruits can be wrapped, so that when the first grip arm 1 and the second grip arm 2 are closed for shearing, they will not slide relative to the branches of citrus fruits, thereby ensuring overall stability during the shearing process;
