Description

Technical Field

[0001] This utility model relates to the field of tea planting technology, specifically a tea pruning device. Background Technology

[0002] Tea cultivation refers to the process of planting tea tree seeds or seedlings in suitable land, and through scientific management and technical means, enabling them to grow, develop and eventually produce tea leaves. After picking, the fresh leaves need to be processed in a timely manner, including processes such as fixation, rolling and drying, in order to make different types of tea.

[0003] In the process of tea cultivation, tea trees have apical dominance, meaning that the growth of the terminal bud or terminal branch inhibits the growth of lateral buds and branches. By pruning and removing the terminal bud or terminal branch, this inhibitory effect can be relieved, allowing the lateral buds below the pruning cut to sprout and grow rapidly, thereby increasing the number of branches of the tea tree, expanding the canopy, and providing more buds and leaves for subsequent harvesting.

[0004] When pruning the top tea leaves, a large amount of loose tea leaves are generated during the process. If not properly handled, this will not only waste resources but may also pose a risk of pests and diseases to the tea garden. Therefore, a tea pruning device is proposed that can prune the tea trees and collect the pruned tea leaves at the same time. Utility Model Content

[0005] In view of the shortcomings of the existing technology, this utility model provides a tea pruning device, the purpose of which is to solve the above problems.

The driven bevel tooth is located in the cavity and meshes with the active bevel tooth, so that the rotation of the driven rod drives the cutting component to rotate.

[0013] Preferably, the air extraction component includes a support rod fixed to the first pulley. The end of the support rod near the first pulley is rotatably connected to the mounting box. The outer surface of the end of the support rod away from the mounting box is uniformly provided with blades. The rotation of the first pulley can drive the entire air extraction component to rotate synchronously.

[0014] Preferably, a second dustproof net is provided at the bottom of the recycling frame corresponding to the air extraction component. The second dustproof net has a discharge hole inside, through which air is exhausted.

[0015] Preferably, the side of the air extraction component away from the installation box is provided with a first dustproof net that is fixed to the inner cavity of the recycling frame.

[0018] Preferably, the bottom of the recycling frame has a discharge hole corresponding to the collection box to facilitate the discharge of tea leaves.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] This utility model provides a tea trimming device that can trim and recycle tea leaves simultaneously. The dual-output shaft motor drives the first pulleys on both sides to rotate simultaneously. The rotation is transmitted to the second pulley through the transmission belt, so that the cutting component and the suction component operate at the same time. The rotating rod drives the blade to rotate and trim the tea leaves, while the support rod drives the blade to rotate and suck in the air. The tea leaves that fall after cutting are sucked into the recycling box for recycling.

[0021] The tea pruning device is height-adjustable, and the cutting components can be moved horizontally according to the spacing between tea trees. The hydraulic telescopic rod is activated to raise and lower the mounting box so that the cutting components can be raised and lowered to the appropriate position according to the required pruning height of the tea trees.

[0030] 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.

[0031] Please see Figure 1 The embodiments proposed in this application are as follows: a tea pruning device includes a base 10, a movable wheel at the bottom of the base 10, an installation box 20 and a handle 11 installed on the upper side of the base 10, the handle 11 is located on the outer end of the installation box 20 and fixed to the base 10, and pushing the handle 11 can drive the tea pruning device to move as a whole through the movable wheel at the bottom of the base 10.

[0032] Please see Figure 1 , Figure 2 and Figure 4 A hydraulic telescopic rod 12 is provided between the mounting box 20 and the base 10. The hydraulic telescopic rod 12 is fixed to the upper end of the base 10, and the output end of the hydraulic telescopic rod 12 is fixed to the mounting box 20. Activating the hydraulic telescopic rod 12 can drive the mounting box 20 to rise and fall. Drive frames 30 are provided on both sides of the outer end of the mounting box 20. A cutting component 40 is rotatably arranged on the lower side of the drive frame 30. The cutting component 40 trims the tea leaves. A collection frame 50 is provided on the lower side of each cutting component 40 and is fixed to the mounting box 20. An air extraction component 90 is rotatably arranged inside the collection frame 50. The air extraction component 90 can suck the trimmed tea leaves into the collection frame 50 for collection. A dual-output shaft motor 70 is installed inside the mounting box 20. The output shafts on both sides of the dual-output shaft motor 70 are respectively connected to a first belt. The wheel 71 can be connected using existing technology. Each first pulley 71 has a second pulley 72 above it. A connecting rod 721, which is rotatably connected to the inside of the mounting box 20, is fixed between the two second pulleys 72 to further support the two second pulleys 72 and facilitate their synchronous rotation. The ends of the two second pulleys 72 that are far apart from each other are fixed to the corresponding drive frame 30. The first pulley 71 is fixedly connected to the corresponding air extraction component 90. A transmission belt 73 is sleeved between the first pulley 71 and the corresponding second pulley 72 above it. After the dual output shaft motor 70 is started, the rotation of the first pulley 71 can be transmitted to the second pulley 72 through the transmission belt 73, so that the drive frame 30 and the air extraction component 90 can operate simultaneously.

[0033] The drive frame 30 includes a sleeve 31 located outside the mounting box 20. A support cylinder 32 is fixed to the side of the sleeve 31 away from the mounting box 20. Electric push rods 33 are respectively provided on both sides of the outer end of the sleeve 31. The electric push rods 33 are fixed to the outer wall of the mounting box 20. The output end of the electric push rods 33 is fixed to the sleeve 31 through a connecting block 331. Simultaneous activation of the two electric push rods 33 can drive the sleeve 31 to move horizontally, thereby driving the cutting component 40 to extend to both sides of the mounting box 20, so that the cutting component 40 can adapt to the spacing between different tea trees. A drive sleeve rod 34 is movably arranged inside the sleeve 31. The end of the moving sleeve rod 34 away from the cutting component 40 is fixed to the corresponding second pulley 72 and rotatably connected to the side wall of the mounting box 20, so that the rotation of the second pulley 72 can drive the driving sleeve rod 34 to rotate. Thus, the sleeve 31 can slide on the outside of the driving sleeve rod 34, and the driving sleeve rod 34 can also rotate inside the sleeve 31. A driven rod 35 is slidably arranged inside the driving sleeve rod 34. The end of the driven rod 35 away from the mounting box 20 is rotatably connected to the sleeve 31, so that the sleeve 31 can drive the driving sleeve rod 34 to translate after translation, without interfering with the rotation of the driven rod 35.

[0034] Please see Figure 4 and Figure 5 The outer surface of the driven rod 35 is provided with four slide bars 351, and the inside of the drive sleeve 34 is provided with four slide grooves that are adapted to the slide bars 351. When the drive sleeve 34 rotates, the driven rod 35 can be driven to rotate synchronously through the docking of the slide bars 351 with the slide grooves inside the drive sleeve 34.

[0035] The cutting component 40 includes a rotating rod 41 rotatably connected to the lower end of the support cylinder 32. Blades 42 are uniformly fixed on the outer surface of the lower end of the rotating rod 41. The rotation of the rotating rod 41 drives the blades 42 to rotate, thereby trimming and cutting the tea leaves. The support cylinder 32 has a cavity. A driven bevel tooth 411 is fixed at the upper end of the rotating rod 41. The driven bevel tooth 411 is located in the cavity. The end of the driven rod 35 away from the mounting box 20 extends into the cavity and is fixed with an active bevel tooth 352. The active bevel tooth 352 meshes with the driven bevel tooth 411, so that when the driven rod 35 rotates, it can drive the entire cutting component 40 to rotate, allowing the blades 42 to perform trimming operations.

[0036] The exhaust component 90 includes a support rod 91 fixed to the first pulley 71. One end of the support rod 91 near the first pulley 71 is rotatably connected to the mounting box 20. Rotation of the first pulley 71 drives the support rod 91 to rotate. A plurality of blades 92 are evenly distributed on the outer surface of one end of the support rod 91, away from the mounting box 20. When the support rod 91 rotates, it drives the blades 92 to rotate, drawing outside air into the recovery frame 50. This creates a negative pressure in the chamber of the recovery frame 50 away from the exhaust component 90. Tea leaves that fall after being trimmed by the cutting component 40 are drawn into the recovery frame 50. A second dustproof net 501 is provided at the bottom of the recovery frame 50 corresponding to the exhaust component 90. The second dustproof net 501 has a built-in discharge hole 502. The second dustproof net 501 facilitates the exhaust of air drawn into the recycling frame 50 by the suction component 90. The discharge hole 502 intercepts external dust. A first dustproof net 51 is provided on the side of the suction component 90 away from the installation box 20 and is fixed to the inner cavity of the recycling frame 50 to intercept the dust drawn into the recycling frame 50 and reduce the amount of dust in contact with the suction component 90. The first dustproof net 51 has built-in brackets 52 that are fixed to the four corners of the inner cavity of the recycling frame 50. The support rod 91 is rotatably connected to the brackets 52. The brackets 52 provide support points for the end of the support rod 91 away from the installation box 20, thereby improving the support effect.

[0037] When using this tea pruning device, first activate the hydraulic telescopic rod 12 to raise and lower the mounting box 20 so that the cutting component 40 can be raised and lowered to the appropriate position according to the required pruning height of the tea tree. Then, activate the electric push rod 33 to move the sleeve 31 horizontally, so that the cutting components 40 on both sides can be extended. Adjust the cutting components 40 on both sides of the mounting box 20 to the appropriate position according to the distance between the tea trees.

[0038] When trimming tea leaves, the dual-shaft motor 70 is started to drive the first pulleys 71 on both sides to rotate simultaneously. The rotation is transmitted to the second pulley 72 through the transmission belt 73. At the same time, the active bevel gear 352 and the driven bevel gear 411 mesh to transmit the rotation of the drive sleeve 34 to the rotating rod 41. Thus, the cutting component 40 and the suction component 90 operate simultaneously. The rotating rod 41 drives the blade 42 to rotate and trim the tea leaves. The support rod 91 drives the blade 92 to rotate and suck air. The tea leaves that fall after cutting are sucked into the recycling box 50 for recycling.

[0039] In further embodiments, please refer to Figure 1 , Figure 3 and Figure 6The bottom of the recycling frame 50 is equipped with a collection box 60. Tea leaves collected by the recycling frame 50 fall into the collection box 60 for collection. A discharge hole 502 is provided at the bottom of the recycling frame 50 corresponding to the collection box 60, so that the tea leaves sucked into the recycling frame 50 can fall into the collection box 60 through the discharge hole 502. Locking blocks are fixed on both sides of the outer wall of the recycling frame 50 to position the collection box 60 after it is installed with the recycling frame 50. The locking block includes a support block 80 fixed to the outer wall of the recycling frame 50, and a connecting joint 81 is slidably provided in the support block 80. The connector 81 has limiting blocks at both ends, which are slidingly connected to the support block 80 in a limiting manner, preventing it from falling off the support block 80. The support block 80 has a limiting groove, and a return spring 82 is built into the limiting groove. The return spring 82 will abut the connector 81. The elastic force of the return spring 82 can push the connector 81 to move outward of the support block 80. The upper end of the connecting frame 61 has a mating hole, so that the connector 81 can be engaged with the limiting hole of the connecting frame 61 after it pops out of the recycling frame 50, and the collection box 60 after the recycling frame 50 is installed can be quickly fixed.

[0040] When the collection box 60 is installed with the recycling frame 50, the locking block fixes the collection box 60. Tea leaves sucked into the recycling frame 50 can enter the collection box 60 for collection. The locking block allows the collection box 60 to be quickly attached and detached from the recycling frame 50. When the collection box 60 needs to be removed from the recycling frame 50, simply press the connector 81 into the limiting groove. When the connector 81 is no longer engaged with the corresponding connecting bracket 61, the connecting bracket 61 can be separated from the locking block, and the collection box 60 can be quickly removed from the recycling frame 50.
