Abstract
Description
Technical Field
[0001] This utility model relates to the field of agricultural machinery technology, and more specifically to a tea tree pruning device. Background Technology
[0002] Pruning is a frequent practice in tea garden management. Pruning guides the main trunk and lateral branches to grow in the desired direction, regulating lateral branch growth, promoting branching, controlling height, accelerating lateral expansion, and quickly transforming single-axis branches into sympodial branches. This results in a rational branching structure and robust main branches, laying a solid foundation for cultivating a high-quality, high-yield canopy. Furthermore, shaping and pruning effectively improve ventilation and light penetration, reducing pests and diseases and promoting healthy tea tree growth.
[0003] Tea trees are usually planted in rows, but existing tea tree pruning devices can only prune one row of tea trees at a time, resulting in low pruning efficiency. Furthermore, existing tea tree pruning devices are not convenient for users to prune tea trees of different heights and widths. In addition, during the pruning process, the pruned tea leaves fall directly onto the tea trees, which can affect the normal photosynthesis of the tea trees. Utility Model Content

[0020] To facilitate understanding of this utility model, a more comprehensive description of the utility model will be given below with reference to the accompanying drawings, which show several embodiments of the utility model. However, the utility model can be implemented in different forms and is not limited to the embodiments described in the text. On the contrary, these embodiments are provided to make the disclosure of the utility model more thorough and comprehensive.
[0021] This utility model provides a tea tree pruning device; please refer to [reference needed]. Figures 1-4 As shown, it includes a base 1, with casters at the bottom and a push handle on one side of the top of the base 1. Height adjustment mechanisms 2 are provided on both sides of the top of the base 1. Width adjustment mechanism 3 is provided on the top of the height adjustment mechanism 2. Width adjustment mechanism 3 includes a top plate 31 on top of the height adjustment mechanism 2. A pruning mechanism 4 for pruning tea trees is provided at the bottom of the top plate 31. The pruning mechanism 4 includes a top pruning component and a side pruning component. A cleaning component 5 is also provided at the bottom of the top plate 31.
[0022] In this embodiment, the two sets of pruning mechanisms 4 push the push handle of the base 1, and with the assistance of the moving wheels, the device can be moved easily, thus facilitating the simultaneous pruning of two rows of tea trees and greatly improving the efficiency of tea tree pruning. During pruning, the height adjustment mechanism 2 allows for flexible adjustment of the height of the pruning mechanism 4, and the width adjustment mechanism 3 allows for adjustment of the distance between the two pruning components, making it suitable for tea trees of different heights and widths. At the same time, the cleaning component 5 facilitates the cleaning of tea leaves that fall onto the tea trees, ensuring the normal photosynthesis of the tea trees.
[0023] Furthermore, the height adjustment mechanism 2 includes a side plate 21 fixedly connected to the top of the base 1, a first dual-axis motor 22 fixedly installed on the top of the base 1, and a lead screw 26 rotatably installed in the side plate 21 via bearings. Both output ends of the first dual-axis motor 22 are fixedly connected to a rotating shaft 23. One end of the rotating shaft 23 is fixedly connected to a driving bevel gear 24. One side of the driving bevel gear 24 is meshed with a driven bevel gear 25 fixedly sleeved on the lead screw 26. One end of the driven bevel gear 25 is threadedly connected to a U-shaped frame 27.
[0024] In use, the U-shaped frame 27 extends through the top of the side plate 21 to the outside, and the inner walls of both sides of the side plate 21 are provided with sliding grooves. The bottom of both sides of the U-shaped frame 27 are provided with sliders that slide in connection with the sliding grooves, so that the U-shaped frame 27 moves up and down more smoothly. By starting the first dual-axis motor 22, the first dual-axis motor 22 drives the rotating shaft 23 to rotate, the rotating shaft 23 drives the driving bevel gear 24 to rotate, and the meshing of the driving bevel gear 24 and the driven bevel gear 25 drives the lead screw 26 to rotate, thereby driving the U-shaped frame 27 to move up and down, and then driving the top plate 31 to move up and down, thereby driving the pruning mechanism 4 to move up and down. This allows for flexible adjustment of the height of the pruning mechanism 4 to suit tea trees of different heights, making it convenient to prune tea trees of different heights.
[0025] Furthermore, the width adjustment mechanism 3 includes a top plate 31 fixedly connected to the top of the U-shaped frame 27, a connecting plate 33 fixedly connected between the two top plates 31, and a through groove 32 opened at the bottom of the top plate 31. A second dual-axis motor 34 is fixedly installed on the top of the connecting plate 33. A forward and reverse threaded rod 35 is rotatably connected in the through groove 32 through a bearing. The end of the forward and reverse threaded rod 35 extending through the top plate 31 to the outside is connected to the output end of the second dual-axis motor 34. The two ends of the forward and reverse threaded rod 35 located in the through groove 32 are symmetrically threaded to a moving block 36. A moving plate 37 is fixedly connected to the bottom of the moving block 36.
[0026] In use, by starting the second dual-axis motor 34, the second dual-axis motor 34 drives the forward and reverse threaded rods 35 to rotate. The forward and reverse threaded rods 35 drive the two moving blocks 36 to move towards the center along the through groove 32, thereby driving the two moving plates 37 to move towards the center, and then driving the two second blades 46 to move towards the center. This allows for flexible adjustment of the distance between the two second blades 46 according to the width of the tea tree, thus adapting to pruning tea trees of different widths and making it highly versatile.
[0027] Furthermore, the top trimming assembly includes a first motor 41 fixedly mounted on the bottom mounting bracket of the top plate 31, with a first rotating rod 42 fixedly connected to the output end of the first motor 41, and a first blade 43 fixedly connected to one end of the first rotating rod 42; the side trimming assembly includes a second motor 44 fixedly mounted on one side of the movable plate 37, with a second rotating rod 45 fixedly connected to the output end of the second motor 44, and a second blade 46 fixedly connected to one end of the second rotating rod 45 that passes through the movable plate 37.
[0028] In use, by starting the first motor 41, the first motor 41 drives the first rotating rod 42 to rotate, and the first rotating rod 42 drives the first blade 43 to rotate, thereby pruning the top of the tea tree. At the same time, by starting the second motor 44, the second motor 44 drives the second rotating rod 45 to rotate, and the second rotating rod 45 drives the second blade 46 to rotate, thereby pruning the sides of the tea tree.
[0029] Furthermore, the cleaning assembly 5 includes a first arc-shaped cleaning brush plate 51 and a second arc-shaped cleaning brush plate 52. The first arc-shaped cleaning brush plate 51 and the second arc-shaped cleaning brush plate 52 are respectively connected to the moving plate 37 through a connecting rod 55. The inner wall of the second arc-shaped cleaning brush plate 52 is provided with a T-shaped sliding groove 54. One end of the first arc-shaped cleaning brush plate 51 is fixedly connected to a T-shaped slider 53 that is slidably connected to the T-shaped sliding groove 54. In use, the first arc-shaped cleaning brush plate 51 is a soft PU strip that can be bent and also has tear resistance.
[0030] In use, the two movable plates 37 move relative to each other along the through groove 32, causing the first arc-shaped cleaning plate 51 and the second arc-shaped cleaning plate 52 to move relative to each other. The T-shaped slider 53 slides along the T-shaped slide groove 54, making the relative movement of the first arc-shaped cleaning plate 51 and the second arc-shaped cleaning plate 52 more stable. This allows for flexible adjustment according to the width of the tea tree. The first arc-shaped cleaning plate 51 and the second arc-shaped cleaning plate 52 are connected to form an arc-shaped structure, which cleans up the tea leaves that have fallen from the pruned tea tree, thus ensuring the normal photosynthesis of the tea tree.
[0031] The working principle of this utility model is as follows: In use, the two sets of pruning mechanisms 4 push the push handle of the base 1, and with the assistance of the moving wheels, the device can be moved to facilitate the simultaneous pruning of two rows of tea trees. During pruning, the side plate 21 is activated, which drives the two rotating shafts 23 to rise and fall, thereby driving the two sets of pruning mechanisms 4 to rise and fall synchronously. After the height is adjusted, the second dual-axis motor 34 is activated, which drives the two forward and reverse threaded rods 35 to rotate, thereby driving the second blades 46 on both sides to move towards the middle. This allows for flexible adjustment according to the actual height and width of the tea trees, making it suitable for tea trees of different heights and widths, and facilitating the pruning of tea trees of different heights and widths. At the same time, the cleaning component 5 facilitates the cleaning of tea leaves that fall on the tea trees after pruning, ensuring the normal photosynthesis of the tea trees.
[0032] The present invention has been described above by way of example in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvement made by adopting the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution of the present invention to other occasions without modification, shall be within the protection scope of the present invention.
