Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of plant cultivation, in particular to a cutting seedling cutting knife. Background Art
[0002] Cuttings, also known as cuttings, are a common propagation method for cultivating plants. You can cut the stems, leaves, roots, buds, etc. of the plant (called cuttings in horticulture), or insert them into the soil, sand, or soak them in water. After they take root, they can be planted to make them independent new plants. In agricultural and forestry production, different plants have different requirements for conditions when they are cut. Only by understanding and complying with their needs can a higher success rate of reproduction be achieved. At this stage, in order to ensure the success rate of grafting cultivation, plants need to be cut on an angle to increase the grafting area.
[0003] However, the existing technology for cutting the branches of seedlings is either to use flower and tree shears for manual cutting or to use a shear for cutting, both of which are inefficient and cannot be operated on a batch of branches at the same time. In addition, the cutting angles will vary due to objective factors. Flower and tree shears can only be used to operate one branch at a time, while a shear can be used to operate multiple branches at a time. However, because the branches are tough and the bark of the branches is tougher, cutting multiple branches at the same time will result in uncut branches, residual bark, etc., and the branches are not straight, and cutting multiple branches at the same time will result in different cutting angles. Therefore, further improvement is needed. Summary of the invention

DETAILED DESCRIPTION
[0021] The following will be combined with 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 of 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. Example
[0022] like Figure 1~Figure 4 As shown, this embodiment proposes a cutting seedling cutting knife, including a knife groove 1 and a knife body 2. Four supporting feet 3 are fixedly installed at the bottom of the knife groove 1, and a knife handle 4 is fixedly installed on the knife body 2. Two toothed left card slots 5.1 and right card slots 5.1 are installed on both sides of the outside of the knife groove 1, wherein the right card slot 5.1 is fixedly connected to the front baffle 1.1 and the rear baffle 1.2 at both ends, and the front and rear ends of the track 7 are fixedly connected to the front baffle 5.1 and the rear baffle 5.2. The left card slot 5.1 is movably connected to the knife groove 1 through the track 7, and can be moved along the knife groove 1. It moves left and right along the track 7; the front baffle 1.1, the rear baffle 1.1, the left card slot 5.1 and the right card slot 5.1 together constitute the knife slot 1; two cutting boards 6 are installed on both sides of the outside of the knife slot 1, and the cutting boards 6 are connected to the left card slot 5.1 and the right card slot 5.2 through a tenon assembly 14, and the tenon assembly 14 consists of a fixed seat 10 and a support frame 11, the support frame 11 is axially installed on the fixed seat 10, and the cutting board 6 is axially connected to the fixed seat 10; the front end of the knife body 2 is connected to the front baffle 1.1 through a shaft sleeve 9, and a handle 4 is provided at the rear of the knife body 2.
[0023] In this embodiment, the left card slot 5.1 and the right card slot 5.2 are symmetrically distributed, and there are a number of latch teeth 5.3 symmetrically distributed on the left card slot 5.1 and the right card slot 5.2; there are two cutting boards 6, corresponding to the outer sides of the left card slot 5.1 and the right card slot 5.2 respectively; there are four tenon assemblies 14, which are respectively installed at the corresponding positions of the left and right card slots.
[0024] In this embodiment, the front and rear ends of the track 7 are fixed to the front baffle 1.1 and the rear baffle 1.2 by two screws 13, and the screws 13 can be used for disassembly, assembly and maintenance of the track 7.
[0025] In this embodiment, the left slot 5.1 is mounted on the track 7 by butterfly screws 8, and there are at least two butterfly screws 8.
[0026] In this embodiment, the two chopping boards 6 are axially connected to the fixing base 10 and can be flipped along the axis. When not in use, they are stored outside the left card slot 5.1 and the right card slot 5.2. When in use, the chopping board 6 is flipped to an angle of more than 45°, and the support frame 11 is rotated to the bottom of the chopping board 6 to form a support.
[0027] In this embodiment, a level 12 is fixedly installed above the handle 4, and the top of the level 12 is transparent.
[0028] When using, when it is necessary to cut the seedlings, the staff first needs to turn over the chopping board 6, and then rotate the support frame 11 to support the chopping board 6, the chopping boards on both sides form an operating table, and then the staff places multiple seedlings one by one between the clamping teeth 5.3 on the left clamping slot 5.1 and the right clamping slot 5.2, and the seedlings at this time will be supported by the chopping board 6; the staff then loosens the butterfly screw 8, pulls the left clamping slot 5.1 backward along the track 7 to the required angle, and tightens the butterfly screw 8. Since the left clamping slot 5.1 and the right clamping slot 5.2 are in a staggered state, the placement state of the seedlings is a horizontal oblique state, and will be fixed by the clamping teeth 5.3 corresponding to the left and right clamping slots, and then the staff holds the knife handle 4 downward and rotates it. The knife handle 4 will synchronously drive the cutter body 2 to rotate during the rotation process, and will rotate with the shaft sleeve 9 as the center of the circle during the rotation process and cut the seedlings. Since the seedlings are in an oblique state, an inclined surface will be generated after being cut, which is convenient for subsequent grafting work;
[0029] When it is necessary to increase or decrease the cutting bevel of the seedlings, the staff needs to loosen the butterfly screw 8, pull the left slot 5.1 by hand to move it forward and backward along the track 7, and tighten the butterfly screw 8 to fix the left slot 5.1 after determining the required bevel angle, so as to control the bevel angle of the seedlings.
[0030] In this embodiment, a level 12 is fixedly connected above the knife handle 4. The top of the level 12 is transparent, which can be used to easily determine whether the cutter is placed in a horizontal state to ensure the safety of subsequent operations.
[0031] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
