Description

Technical Field

[0001] This utility model relates to the field of tea garden pruning technology, and in particular to a centrifugal tea garden pruning shear disc angle adjustment device. Background Technology

[0002] Tea garden pruning refers to the agricultural management measure of removing and tidying up the branches and leaves of tea trees by means of manual or mechanical methods using pruning shears to promote the healthy growth of tea trees and improve the yield and quality of tea. By removing old branches, diseased branches and overly dense branches and leaves, the sprouting of new shoots can be stimulated while maintaining the height and shape of the tea tree, making it easier to harvest and manage.

[0003] When using a pruning shear disc to prune tea gardens, workers need to rotate and move the device to adjust the appropriate pruning angle. In environments with limited space, it is not convenient to adjust the angle of the pruning shear disc according to the actual pruning needs, resulting in a single pruning angle and affecting pruning efficiency.

[0004] Therefore, to address the issue that workers need to rotate and move the device to adjust the appropriate pruning angle, which is inconvenient for adjusting the angle of the pruning shear disc according to actual pruning needs, a centrifugal adjustment structure is set up. During the pruning process, the angle of the shear disc is adjusted through the principle of centrifugal force, making it easy to adjust the angle of the pruning shear disc according to actual pruning needs, so as to adapt to the pruning needs of different terrains and tea tree heights. Utility Model Content

[0005] To overcome the problem that when using a pruning shear disc to prune tea gardens, workers need to rotate and move the device to adjust the appropriate pruning angle. In environments with limited space, it is not convenient to adjust the angle of the pruning shear disc according to the actual pruning needs, resulting in a single pruning angle and affecting pruning efficiency.

[0006] The technical solution of this utility model is as follows: a centrifugal tea garden pruning shear disc angle adjustment device, including a support base, an adjustment motor fixedly connected to the bottom surface of the support base, a rotating shaft fixedly connected to the output end of the adjustment motor, a centrifugal turntable fixedly connected to the outer side of the rotating shaft, a fixed seat fixedly connected to the outer side of the rotating shaft, a guide rod fixedly connected to the outer side of the fixed seat, a centrifugal block slidably connected to the outer side of the guide rod, and a spring slidably sleeved on the outer side of the guide rod.

[0007] Preferably, the bottom surface of the fixed base is fixedly connected to the top surface of the centrifugal turntable, the guide rod is fixedly connected to the inner wall of the centrifugal turntable, the guide rod is evenly distributed within the centrifugal turntable, one end of the spring is fixedly connected to the side of the fixed base, and the other end of the spring is fixedly connected to the centrifugal block.

[0008] Preferably, the centrifugal block is rotatably connected to a support rod, the end of the support rod is rotatably connected to a rotating base plate, and the center of the rotating base plate is rotatably connected to a connecting shaft.

[0009] Preferably, a limiting plate is fixedly connected to the bottom surface of the connecting shaft, a connecting block is fixedly connected to the top surface of the connecting shaft, and a limiting slider is fixedly connected to the outer side of the top of the connecting block, with the limiting sliders symmetrically distributed on the connecting block.

[0010] Preferably, a limiting seat is fixedly connected to the top of the inner wall of the support base, the limiting seats are symmetrically distributed within the support base, a limiting slide rod is fixedly connected to the inner wall of the limiting seat, and the limiting slider is slidably connected to the limiting slide rod.

[0011] Preferably, a push seat is fixedly connected to the top surface of the connecting block, a rotating connecting rod is rotatably connected inside the push seat, a rotating frame is rotatably connected to the end of the rotating connecting rod, a rotating seat is rotatably connected to the inner side of the rotating frame, and the bottom surface of the rotating seat is fixedly connected to the bottom surface of the support seat.

[0012] Preferably, a support frame is fixedly connected to the end of the rotating frame, a rotating motor is fixedly connected to the inner wall of the support frame, a rotating cutter head is fixedly connected to the output end of the rotating motor, and rotating blades are fixedly connected to the outer side of the rotating cutter head at equal angles.

[0013] The beneficial effects of this utility model are:

[0014] 1. In tea garden pruning, when it is necessary to adjust the angle of the rotating cutter head, the motor drives the rotating shaft to rotate, which in turn drives the centrifugal turntable and the fixed seat to rotate. During the rotation, the centrifugal block slides outward along the guide rod under the action of centrifugal force, stretching the spring. The elastic force of the spring is used to balance the centrifugal force, ensuring that the centrifugal block slides smoothly. The sliding of the centrifugal block pushes the rotating base plate to move upward through the support connecting rod, which drives the connecting block to slide along the limit slide rod, ensuring the stability of the movement direction.

[0015] 2. The moving of the connecting block causes the push seat to move upward, and the rotating rod drives the rotating frame to rotate around the rotating seat. When one end of the rotating frame moves upward, the other end will rotate downward, thereby changing the angle of the support frame and realizing the angle adjustment of the rotating cutter head. By controlling the speed of the adjusting motor, the position of the centrifugal block on the guide rod is changed, and the adjustment angle of the rotating cutter head is precisely controlled to meet different trimming needs.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-5 This utility model provides an embodiment: a centrifugal tea garden pruning shear disc angle adjustment device, including a support base 1, an adjustment motor 2 fixedly connected to the bottom surface of the support base 1, a rotating shaft 3 fixedly connected to the output end of the adjustment motor 2, a centrifugal turntable 4 fixedly connected to the outside of the rotating shaft 3, a fixed seat 5 fixedly connected to the outside of the rotating shaft 3, a guide rod 6 fixedly connected to the outside of the fixed seat 5, a centrifugal block 7 slidably connected to the outside of the guide rod 6, and a spring 8 slidably sleeved on the outside of the guide rod 6.

[0024] The bottom surface of the fixed base 5 is fixedly connected to the top surface of the centrifugal turntable 4, and the guide rod 6 is fixedly connected to the inner wall of the centrifugal turntable 4. The guide rod 6 is distributed at equal angles inside the centrifugal turntable 4. One end of the spring 8 is fixedly connected to the side of the fixed base 5, and the other end of the spring 8 is fixedly connected to the centrifugal block 7. The rotating shaft 3 is driven to rotate by adjusting the motor 2, thereby driving the centrifugal turntable 4 and the fixed base 5 to rotate. During the rotation, the centrifugal block 7 slides outward along the guide rod 6 under the action of centrifugal force, and stretches the spring 8. During the sliding of the centrifugal block 7, the elastic force of the spring 8 is used to balance the centrifugal force of the centrifugal block 7, ensuring that the centrifugal block 7 slides smoothly.

[0025] The centrifuge block 7 is rotatably connected to a support rod 201. The end of the support rod 201 is rotatably connected to a rotating base plate 202. The center of the rotating base plate 202 is rotatably connected to a connecting shaft 203. When the centrifuge block 7 rotates with the centrifuge turntable 4, the support rod 201 drives the rotating base plate 202 to rotate around the connecting shaft 203. When the centrifuge block 7 slides outward, the support rod 201 pushes the rotating base plate 202 to move upward.

[0026] A limiting plate 204 is fixedly connected to the bottom surface of the connecting shaft 203, and a connecting block 205 is fixedly connected to the top surface of the connecting shaft 203. A limiting slider 206 is fixedly connected to the outer side of the top of the connecting block 205. The limiting slider 206 is symmetrically distributed on the connecting block 205. The upward-moving rotating base plate 202 pushes the connecting block 205 upward through the connecting shaft 203, which drives the limiting slider 206 to move, thereby converting the centrifugal force generated by the centrifugal block 7 into the power for the connecting block 205 to move.

[0027] A limiting seat 207 is fixedly connected to the top of the inner wall of the support base 1. The limiting seats 207 are symmetrically distributed within the support base 1. A limiting slide rod 208 is fixedly connected to the inner wall of the limiting seat 207. The limiting slider 206 is slidably connected to the limiting slide rod 208. During the movement of the connecting block 205, the limiting slider 206 is driven to slide on the limiting slide rod 208, limiting the movement direction of the connecting block 205 and ensuring the stability of the movement of the connecting block 205.

[0028] A push seat 301 is fixedly connected to the top surface of the connecting block 205. A rotating connecting rod 302 is rotatably connected inside the push seat 301. A rotating frame 303 is rotatably connected to the end of the rotating connecting rod 302. A rotating seat 304 is rotatably connected to the inner side of the rotating frame 303. The bottom surface of the rotating seat 304 is fixedly connected to the bottom surface of the support base 1. The push seat 301 is moved by the upward-moving connecting block 205, so that the rotating frame 303 can be moved around the rotating seat 304 by the rotating connecting rod 302. When one end of the rotating frame 303 is pushed upward, the other end of the rotating frame 303 will rotate downward, thereby changing the angle and direction of the support frame 305.

[0029] A support frame 305 is fixedly connected to the end of the rotating frame 303. A rotating motor 306 is fixedly connected to the inner wall of the support frame 305. A rotating cutter disc 307 is fixedly connected to the output end of the rotating motor 306. Rotating blades 308 are fixedly connected to the outer side of the rotating cutter disc 307 at equal angles. The support frame 305 provides support for the rotating motor 306. The rotating motor 306 drives the rotating cutter disc 307 to rotate, which in turn drives the rotating blades 308 to rotate, thereby pruning the tea trees.

[0030] Working principle: According to Figure 1 and Figure 5 As shown, during operation, the rotating motor 306 drives the rotating blade 307 to rotate, which in turn drives the rotating blade 308 to rotate, thereby pruning the tea tree.

[0031] according to Figures 2-3 As shown, when it is necessary to adjust the angle of the rotating blade 307, the rotating shaft 3 is driven to rotate by adjusting the motor 2, thereby driving the centrifugal turntable 4 and the fixed seat 5 to rotate. During the rotation, the centrifugal block 7 slides outward along the guide rod 6 under the action of centrifugal force, and stretches the spring 8.

[0032] according to Figures 2-4 As shown, when the centrifugal block 7 slides outward, the supporting connecting rod 201 pushes the rotating base plate 202 to move upward. During the movement, the connecting shaft 203 pushes the connecting block 205 to move upward, thereby causing the limiting slider 206 to slide on the limiting slider 208, limiting the movement direction of the connecting block 205 and ensuring the stability of the movement of the connecting block 205.

[0033] according to Figures 2-5 As shown, the upward-moving connecting block 205 pushes the pusher seat 301 to move, and the rotating link 302 pushes the rotating frame 303 to move around the rotating seat 304. When one end of the rotating frame 303 is pushed upward, the other end of the rotating frame 303 will rotate downward. The angle of the rotating cutter head 307 is adjusted by changing the angle of the support frame 305. The position of the centrifugal block 7 on the guide rod 6 is changed by controlling the rotation speed of the adjusting motor 2, thereby controlling the adjustment angle of the rotating cutter head 307.

[0034] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0035] 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.
