Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of leaf cutters, in particular to a leaf cutter for pruning and crushing tea tree branches and leaves. Background Technique
[0002] Tea leaves are picked from tea trees in the fields. With the modern tea tree planting technology and the standardized management of tea trees, the pruning of tea tree branches has become an important task. In the long history of tea tree planting, in order to better trim tea trees, many auxiliary tools for pruning tea trees have been gradually developed.
[0003] When tea farmers prune the branches and leaves of tea trees, the auxiliary tool commonly used is a leaf cutter. A small leaf cutter can be operated by a single person. The existing leaf cutter is composed of a telescopic motor, a cutting knife, a bracket, etc. According to the structural type, it can be divided into a single-knife type and a double-knife type. The single-knife type structure is more portable, and the double-knife type can perform two-way cutting, and its cutting efficiency is higher.
[0004] However, the distance between the two cutting knives of the double-knife type leaf cutter cannot be adjusted. When the distance between the required tea trees on both sides changes, it cannot make an adaptive adjustment according to the distance.
[0005] Therefore, a leaf cutter for pruning and crushing tea tree branches and leaves is proposed. Content of the Utility Model
[0006] The purpose of the utility model is to provide a leaf cutter for pruning and crushing tea tree branches and leaves. By setting two telescopic motors that can slide relative to each other, the distance between the telescopic motors can be adaptively adjusted according to the distance between the tea trees on both sides, so as to solve the problems raised in the above background technique.
[0007] To achieve the above purpose, the utility model provides the following technical solutions:
[0008] A leaf cutter for pruning and crushing tea tree branches and leaves, including a support frame, support wheels, telescopic motors, and cutting knives. The support wheels are rotatably installed on the support frame. A support rod is fixedly installed at the top of the support frame. One end of the support rod away from the support frame is fixedly connected to a cross plate. A slide rail is provided on the cross plate. Two telescopic motors are slidably installed on the slide rail. There are also two cutting knives. The two cutting knives are respectively fixedly installed at the output ends of the two telescopic motors.
[0009] Furthermore, through holes are opened at the tops of the two telescopic motors, and locking bolts are threadedly connected to the through holes. A plurality of limiting holes are provided at intervals on the cross plate.
[0010] Furthermore, a handle is fixedly provided at the top of the cross plate. The handle is in an inverted L shape, and a buffer block is fixedly connected to the bottom of the handle.
[0011] Furthermore, one side of each of the two telescopic motors is fixedly connected with an inclined rod, and a groove is formed in the inclined rod. The bottom of the cutting knife is located in the groove.
[0012] Furthermore, a plurality of blades arranged at intervals are provided on the cutting knife, and each blade is rectangular.
[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0014] 1. Slide rails are arranged on the cross plate, and the two telescopic motors are slidably installed on the slide rails. When the distance between the two sides of the tea trees to be pruned changes, the two telescopic motors can be moved to adjust the distance between the two cutting knives, so as to make an adaptive adjustment according to the distance between the tea trees.
[0015] 2. Two handles are provided for manual operation, and the distance between the top and the bottom of the handle is equal to the radius of the support wheel. When not in use, the handle can be used for support to keep the leaf cutter horizontally placed, and the buffer block contacting the ground can play a buffer protection role for the leaf cutter.

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0020] Please refer to Figures 1 to 2 , the present utility model provides a leaf cutter for pruning and crushing tea tree branches and leaves, and the technical solutions are as follows:
[0021] A tea tree pruning leaf chopper for shredding branches and leaves, comprising a support frame 1, support wheels 2, telescopic motors 5, and cutting blades 4. The support wheels 2 are rotatably installed on the support frame 1. A support rod 3 is fixedly installed at the top of the support frame 1. One end of the support rod 3 away from the support frame 1 is fixedly connected to a cross plate 7. A slide rail 8 is provided on the cross plate 7. Two telescopic motors 5 are slidably installed on the slide rail 8. There are also two cutting blades 4, and the two cutting blades 4 are respectively fixedly installed at the output ends of the two telescopic motors 5.
[0022] A part of the telescopic motor 5 is provided with a crank-rocker mechanism. The crank-rocker mechanism converts the rotary output of the motor into a linear reciprocating motion output, enabling the two cutting blades 4 to perform high-speed reciprocating cutting movements driven by the telescopic motor 5. Manually place the leaf chopper between two rows of tea trees and push the leaf chopper to move, so that the branches and leaves of the tea trees come into contact with the cutting blades 4. The branches and leaves are cut off under the high-speed movement of the cutting blades 4. A plurality of rectangular blades are arranged at intervals on the cutting blades 4. By setting the blades as rectangular, it is easy for the branches and leaves to enter between two adjacent blades, which helps the blades to crush and cut the branches and leaves.
[0023] Manually can measure the distance between rows of tea trees visually, and push the two telescopic motors 5 to move along the slide rail 8 according to the size of the distance for adaptive adjustment to achieve a better pruning effect.
[0024] Through holes are opened at the tops of the two telescopic motors 5, and locking bolts 12 are threadedly connected to the through holes. A plurality of limit holes 10 are arranged at intervals on the cross plate 7. After moving the telescopic motor 5 to an appropriate position, rotate the fastening bolt on the through hole. The fastening bolt moves downward and aligns with one of the limit holes 10 to form a good limit and fixing effect, making it difficult for the telescopic motor 5 to automatically shift during operation and ensuring its high operating stability.
[0025] A handle 9 is fixedly provided at the top of the cross plate 7. The handle 9 is in an inverted L shape, and a buffer block 11 is fixedly connected to the bottom of the handle 9. During actual use, manually hold the handle 9 to push the leaf chopper, which is more conducive to manual operation. Moreover, the distance between the top and the bottom of the handle 9 is equal to the radius of the support wheel 2. When not in use, the handle 9 can be used for support to keep the leaf chopper placed horizontally. The buffer block 11 contacting the ground can play a buffer and protection role for the leaf chopper.
[0026] Oblique rods 6 are fixedly connected to one side of the two telescopic motors 5, and grooves are opened on the oblique rods 6. The bottom of the cutting blade 4 is located in the groove. Since the cutting blade is relatively thin and is prone to bending under force, the groove is provided to limit the cutting blade 4, restricting the cutting blade 4 to perform reciprocating movements along the direction defined by the groove, and it is not easy for the cutting blade 4 to bend and deform during operation.
[0027] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
