Description

Technical Field

[0001] This utility model relates to the field of pruning tools, and in particular to a pruning device for tea cultivation. Background Technology

[0002] The main reasons for pruning in tea cultivation are as follows: First, it stimulates the sprouting of new buds. Pruning removes old and withered leaves and some branches, allowing nutrients to be concentrated on the new buds. Second, it regulates the canopy structure, shaping a reasonable canopy height and branching layers, which helps reduce the occurrence of pests and diseases. Third, it removes diseased and pest-infested branches. Timely pruning of branches affected by pests and diseases can effectively prevent the spread of pests and diseases, ensuring the healthy growth of tea trees. Fourth, it regulates the balance of growth. Reproductive growth and vegetative growth compete for nutrients. Pruning can inhibit reproductive growth and promote vegetative growth, allowing tea trees to better accumulate nutrients and improve the quality of tea.

[0003] There are several types of pruning shears commonly used in tea cultivation. Short-bladed shears require one hand to hold the handle and the other to support the tea branch; the blade is then gently snipped along the area to be pruned. Longer-bladed shears have sharper blades and can quickly prune tea branches; these require both hands to hold the handle, placing the blade at the appropriate position on the branch, and pushing forward or pulling back to complete the pruning. Other types of pruning shears have thick, sturdy blades and are used to cut thicker tea branches; these require both hands to firmly grip the handle, placing the branch between the blades, and then closing the handles to cut the branch.

[0004] In existing technologies, when pruning branches and leaves with shears, it is impossible to fix the discarded branches and leaves to be pruned. Returning the discarded branches and leaves to the field will lead to the accumulation and growth of pathogenic microorganisms such as bacteria and fungi, increasing the risk of tea tree diseases. Furthermore, the scattered branches and leaves may block sunlight and hinder air circulation, affecting the growth of tea trees. At the same time, it will cause inconvenience to subsequent cleanup work, increase labor costs, and be detrimental to the efficient management of tea gardens and the healthy growth of tea trees. Therefore, a pruning device for tea cultivation is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a pruning device for tea cultivation, which aims to improve the problem that the existing pruning devices for tea cultivation cannot fix the discarded branches and leaves that need to be pruned, which leads to diseases caused by returning them to the field.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a pruning device for tea cultivation, comprising a blade holder, a connecting piece fixedly connected to the end of the blade holder, a blade provided on the outer wall of the connecting piece, a fixing ring one provided on the outer wall of the blade holder, a fixing ring two hinged to the fixing ring one, a magnet one fixedly connected to the outer wall of the fixing ring one, a magnet two magnetically connected to the outer wall of the magnet one, a connecting block fixedly connected to the outer wall of the fixing ring one, a connecting rod fixedly connected to the inner wall of the connecting block, a clamping plate one fixedly connected to the end of the connecting rod, a through groove opened through the outer wall of the clamping plate one, a rotating shaft rotatably connected to the inner wall of the through groove, a clamping plate two fixedly connected to the outer wall of the rotating shaft, a coil spring fixedly connected to the outer wall of the rotating shaft, a fixing block fixedly connected to the top of the clamping plate two, a pull rope fixedly connected to the side wall of the fixing block, a positioning ring fixedly connected to the outer wall of the connecting block, a finger ring fixedly connected to the end of the pull rope, and a positioning component provided on the outer wall of the blade holder.

[0007] As a further description of the above technical solution:

[0008] The outer wall of the second magnet away from the first magnet is fixedly connected to the inner surface of the second fixing ring, and the first fixing ring and the second fixing ring are sleeved on the outer wall of the tool holder.

[0009] As a further description of the above technical solution:

[0010] The positioning ring is fitted onto the outer wall of the pull rope, and the fixed end of the coil spring is fixedly connected to the inner wall of the through groove.

[0011] As a further description of the above technical solution:

[0012] The positioning component includes a insertion rod, and the outer wall of the tool holder has an insertion hole.

[0013] As a further description of the above technical solution:

[0014] The end of the insertion rod is fixedly connected to the inner surface of the fixing ring, and the outer wall of the insertion rod is adapted to the inner wall of the insertion hole.

[0015] As a further description of the above technical solution:

[0016] A limiting ring is fixedly connected to the outer wall of the tool holder, a limiting hook is fixedly connected to the outer wall of the limiting ring, and a flexible inclined plate is fixedly connected to the outer wall of the limiting hook.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, by setting up a magnetic attraction between magnet one and magnet two and inserting a rod into the insertion hole, the fixing ring is stably and conveniently positioned on the blade holder. The operator pulls the ring to make the pull rope overcome the tension of the coil spring and unfold the clamp plate two, and fixes the pull rope with the limit hook. When cutting, the branch enters between clamp plate one and clamp plate two. At the same time as the blade cuts the branch, the serrated clamp plate immediately clamps the waste branch. The serrated clamp plate simultaneously clamps the waste branches and leaves, effectively preventing the cut diseased branches and leaves from scattering in the field and causing the spread of diseases, and realizing the integrated operation of cutting and diseased branch capture.

[0023] 2. In this utility model, by setting a limiting hook in combination with the inclined guide design of the soft inclined plate and the soft material to effectively buffer the impact, the pull rope is prevented from accidentally coming loose, so that the pull rope can enter smoothly and is not easy to come out, ensuring the stability of the two clamps in the unfolded state. The operator can control the pull rope with one hand through the finger ring, and with the action of holding the knife holder with both hands, the stability of clamping the waste branches and leaves is improved.

Two sets of blade holder 1, connecting piece 2, and blades 3 are respectively provided, and the two sets of connecting pieces 2 are movably connected by pins or pivots. The two sets of blade holders 1 are hinged together in the middle by a common main shaft, allowing them to rotate relative to each other around this shaft. When the two sets of blade holders 1 rotate relative to each other, they drive the connecting plates 2 and the blades 3 to open and close. The cutting edges of the blades 3 interlock to achieve the cutting function. A fixing ring 4 is provided on the outer wall of the blade holder 1. The fixing ring 4 is hinged to a fixing ring 5. The fixing ring 4 and the fixing ring 5 are fitted onto the outer wall of the blade holder 1. The fixing ring 4 and the fixing ring 5 are fitted onto the bottom set of blade holders 1. A magnet is fixedly connected to the outer wall of the fixing ring 4. 6. Magnet 7 is magnetically connected to the outer wall of magnet 6. The outer wall of magnet 7 away from magnet 6 is fixedly connected to the inner surface of fixing ring 5. Fixing ring 4 and fixing ring 5 form a complete ring-shaped object, which is fixed by magnet 6 and magnet 7. A connecting block 10 is fixedly connected to the outer wall of fixing ring 4. A connecting rod 11 is fixedly connected to the inner wall of connecting block 10. A clamping plate 12 is fixedly connected to the end of connecting rod 11. A through groove 13 is opened through the outer wall of clamping plate 12. A rotating shaft 14 is rotatably connected to the inner wall of through groove 13. A clamping plate 16 is fixedly connected to the outer wall. The clamping plate 12 and the clamping plate 16 are both provided with serrations on the opposite side, which can clamp the waste branches and leaves. After clamping, the waste branches and leaves are cut off by the shearing of two sets of blades 3. A coil spring 15 is fixedly connected to the outer wall of the rotating shaft 14. The fixed end of the coil spring 15 is fixedly connected to the inner wall of the through groove 13. There are two sets of coil springs 15, which are located at both ends of the rotating shaft 14 respectively. When the clamping plate 16 is unfolded, the coil spring 15 is in the stretched state. When the clamping plate 16 and the clamping plate 12 are closed, the coil spring 15 is in the normal state.

[0033] Reference Figures 3-4 A fixing block 17 is fixedly connected to the top of the clamping plate 16. A pull rope 18 is fixedly connected to the side wall of the fixing block 17. A positioning ring 19 is fixedly connected to the outer wall of the connecting block 10. The positioning ring 19 is sleeved on the outer wall of the pull rope 18. A finger ring 20 is fixedly connected to the end of the pull rope 18. The finger ring 20 is made of elastic material and can be put on the operator's finger. The operator can pull the pull rope 18 by the finger to control the unfolding of the clamping plate 16. A positioning component is provided on the outer wall of the tool holder 1. The positioning component includes a rod 8 and a hole 9. There are two sets of positioning components. The two sets of positioning components are symmetrically arranged with the central axis of the fixing ring 4 as the axis of symmetry. The end of the rod 8 is fixedly connected to the inner surface of the fixing ring 4. The outer wall of the tool holder 1 has a hole 9. The outer wall of the rod 8 is adapted to the inner wall of the hole 9. The fixing ring 4 first inserts the rod 8 into the hole 9 and then closes the fixing ring 2 5 with the fixing ring 4 to increase the stability of the fixing ring as a whole fixed on the tool holder 1.

[0034] Reference Figure 5 A limiting ring 21 is fixedly connected to the outer wall of the tool holder 1. A limiting hook 22 is fixedly connected to the outer wall of the limiting ring 21. A flexible inclined plate 23 is fixedly connected to the outer wall of the limiting hook 22. The flexible inclined plate 23 can be made of a flexible material, such as rubber or silicone, and can be deformed. The end of the pull rope 18 near the finger ring 20 can enter the interior of the limiting hook 22. The flexible inclined plate 23 blocks the pull rope 18 from moving out during the pulling process. The pull rope 18 is limited, so that when the operator holds two sets of tool holders 1 with both hands, he can control the pull rope 18 with one finger. The flexible inclined plate 23 is set in a downward tilt towards the side away from the limiting ring 21.

[0035] Working principle: First, insert the rod 8 on the fixing ring 4 into the insertion hole 9 of the tool holder 1. After initial positioning, fix the fixing ring 4 and the fixing ring 5 onto the outer wall of the tool holder 1. The fixing ring 4 and the fixing ring 5 are magnetically connected by the magnet 6 on the outer wall of the fixing ring 4 and the magnet 7 on the inner wall of the fixing ring 5, thus assembling the fixing ring 4 and the fixing ring 5 into a complete ring structure, which is stably fixed on the tool holder 1. During operation, the end of the pull rope 18 near the finger ring 20 can naturally enter the interior of the limiting hook 22. The flexible inclined plate 23 provides guidance for the pull rope 18. Due to its special design, the smoothness of the pull rope 18 entering the limiting hook 22 is greater than the smoothness of its removal from the limiting hook 22, thereby effectively restricting the pull rope 18. This allows the operator to hold the tool holder 1 with both hands and use only one finger to easily... The operator can easily control the pull rope 18 by pulling the ring 20 with their fingers. The ring 20 drives the pull rope 18, which in turn pulls the clamp plate 16 to rotate around the shaft 14 and unfold. At this time, the coil spring 15 is stretched. After placing the waste branches and leaves between the clamp plate 12 and the clamp plate 16, the operator releases the ring 20. The coil spring 15 returns to its original position and causes the clamp plate 16 to close with the clamp plate 12. The serrations on the opposite side firmly clamp the waste branches and leaves. The operator holds the two sets of blade holders 1 with both hands and controls the two sets of blade holders 1 to rotate relative to each other around the common main shaft, which drives the connecting plate 2 and the blades 3 to open and close. The staggered blades 3 are used to cut the tea branches and leaves. The cutting of the blades 3 cuts off the branches and leaves, avoiding the risk of disease caused by returning the waste branches and leaves to the field after pruning.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
