Description

Technical Field

[0001] This utility model relates to the technical field of tea picking auxiliary support devices, specifically, to a tea picking auxiliary support device adapted to different tea tree heights. Background Technology

[0002] Tea picking is a crucial preliminary step in tea production and processing. Its efficiency and picking quality directly affect the quality and economic benefits of the finished tea product. Currently, tea picking in my country is still mainly done manually. Pickers need to maintain a fixed posture such as bending over, hunching over, or raising their arms for a long time. Especially for tea trees of different planting areas, varieties, and growth cycles, their heights vary significantly. For shorter tea trees, workers can stand and pick directly. However, when picking taller tea trees, workers cannot reach them due to their height. In this case, it is usually necessary to use corresponding ladders or other tools to assist in the picking.

[0003] However, when using ladders or similar tools for harvesting, the ladders typically need to be placed on the tea trees. Combined with the weight of the workers, this can easily cause the ladders to bend the tea trees or damage their bark, affecting their normal growth. Furthermore, since the ladders rely primarily on two points of support at the bottom, they are prone to slipping and lack stability, making them susceptible to collapse. Finally, the crossbeams on ladder-like frames are generally narrow, leading to foot fatigue from prolonged use. Therefore, we propose an auxiliary support device for tea harvesting that adapts to different tea tree heights. Utility Model Content

[0004] The purpose of this invention is to provide a tea picking auxiliary support device that adapts to different tea tree heights, so as to solve the defects mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A tea-picking auxiliary support device adapted to different tea tree heights includes a base plate, a center plate above the base plate, and a top plate above the center plate. Cylinders are fixedly installed at the center of the upper surface of both the base plate and the center plate. Both the center plate and the top plate are detachably mounted on the corresponding cylinder telescopic shaft ends. A rectangular ring-shaped mesh protective frame is fixedly installed on the upper surface of the top plate. Exposed holes are provided on both ends of the base plate, and handles are fixedly installed between the left and right side walls of the exposed holes.

[0007] Preferably, a plurality of vertically arranged threaded sleeves are fixedly installed on the bottom of the base plate, and a vertically arranged screw is threadedly connected to the internal thread of the threaded sleeve;

[0008] Preferably, a support pad is fixedly installed at the bottom end of the screw, and the outer diameter of the support pad increases sequentially from top to bottom;

[0009] The above two settings facilitate adjustments based on the flatness of the bottom surface, ensuring stable horizontal support for the subsequent base plate.

[0010] Preferably, two symmetrical roller frames are fixedly installed on the side of one end of the base plate, and rollers are rotatably connected to the roller frames;

[0011] This feature allows the device to be stored and transported vertically, with rollers pressing against the ground for easy transport.

[0012] Preferably, an extended support base is fixedly installed at the end of the cylinder telescopic shaft, and both the center plate and the top plate can be detachably installed on the top surface of the corresponding extended support base;

[0013] This setting increases the support area, making the support more secure.

[0014] Preferably, multiple guide sleeves are fixedly installed on the upper surfaces of the base plate and the center plate, and multiple guide posts are fixedly installed on the bottom surfaces of the center plate and the top plate. The guide posts are located in the corresponding guide sleeves and are slidably connected to the guide sleeves.

[0015] This feature makes the center plate and top plate more stable when moving up and down.

[0016] Preferably, a limiting protrusion is fixedly installed on the front side of the top plate, and a hook is rotatably connected to the front side of the bottom plate. The end of the hook is provided with a groove, and the groove is engaged with the limiting protrusion for limiting operation after retraction.

[0017] This feature allows the device to be positioned in a limiting manner after it is stored, preventing the center plate and top plate from unfolding easily.

[0018] Preferably, a limiting plate with an outer diameter larger than the inner diameter of the slot is fixedly installed at the end of the limiting protrusion, and a movable battery box is fixedly installed on the base plate, wherein a mobile power supply is provided inside the movable battery box.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] 1. This utility model achieves a stable connection between the plates by setting a base plate, a center plate, a top plate and a cylinder between them, and cooperating with a widened support base. The cylinder can extend and retract to drive the top plate and the center plate to rise and fall flexibly, achieving precise adaptation to tea trees of different heights. There is no need to place the device on the tea tree, thus avoiding the tea tree from being bent or its bark damaged, and ensuring the normal growth of the tea tree.

[0021] 2. This utility model, through the screw rod in the threaded sleeve at the bottom of the base plate and the bottom support pad, can adjust the support height according to the flatness of the ground. With the guide sleeve on the base plate and the guide column of the corresponding plate, the lifting process is stable and without shaking. Compared with the two-point support of the ladder, it realizes the smooth landing and stable support of the device, thereby preventing slippage and collapse and improving the safety of operation.

[0022] 3. This utility model provides a spacious and protected standing area for harvesters by setting a rectangular ring-shaped mesh protective frame on the top plate, replacing the narrow crossbeams of the ladder. With the flexible height adjustment of the top plate to adapt to the working height, it achieves comfortable support for the harvesters' feet and optimizes their working posture, thereby reducing foot fatigue and improving harvesting efficiency.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0033] Please see Figures 1-3 This utility model provides a technical solution: a tea picking auxiliary support device adapted to different tea tree heights, including a base plate 1, a center plate 2 above the base plate 1, and a top plate 3 above the center plate 2. A cylinder 4 is fixedly installed at the center of the upper surface of both the base plate 1 and the center of the upper surface of the center plate 2. Both the center plate 2 and the top plate 3 are detachably mounted on the corresponding telescopic shaft ends of the cylinder 4. A rectangular ring-shaped mesh protective frame 30 is fixedly installed on the upper surface of the top plate 3. Exposed holes 16 are provided on both ends of the base plate 1. Handles 17 are fixedly installed between the left and right side walls of the exposed holes 16, allowing the cylinder 4 to drive the top plate 3 and the center plate 2 to rise and fall flexibly, adapting to tea trees of different heights. The mesh protective frame 30 ensures standing safety, and the handles 17 facilitate gripping and leverage, achieving a combination of height adjustability and operational protection.

[0034] In this embodiment, the exposed hole 16 can reduce the weight of the base plate 1, making the handling process smoother.

[0035] like Figure 1 As shown, a plurality of vertically arranged threaded sleeves 10 are fixedly installed at the bottom of the base plate 1. The threaded sleeves 10 are internally threaded with vertically arranged screws 11. Support blocks 12 are fixedly installed at the bottom end of the screws 11. The outer diameter of the support blocks 12 increases from top to bottom, so that the level of the base plate 1 can be adjusted by rotating the screws 11. The support blocks 12 increase the contact area with the ground, thereby achieving stable support of the device on uneven ground and preventing shaking and tilting during operation.

[0036] like Figure 1 As shown, two symmetrical roller frames 13 are fixedly installed on the side of one end of the base plate 1. Rollers 14 are rotatably connected to the roller frames 13, so that when the device is stored and placed vertically, the rollers 14 can contact the ground and move the device in conjunction with the handle 17, which realizes convenient transportation and reduces the difficulty of moving the device in the tea garden.

[0037] like Figure 1 As shown, an extended support base 40 is fixedly installed at the end of the telescopic shaft of cylinder 4. Both the center plate 2 and the top plate 3 can be detachably installed on the top surface of the corresponding extended support base 40, which increases the support area of ​​the cylinder 4 on the plate, disperses the force, realizes the stable assembly of the center plate 2 and the top plate 3, and improves the load-bearing stability of the device.

[0038] like Figure 1As shown, multiple guide sleeves 41 are fixedly installed on the upper surfaces of the base plate 1 and the center plate 2, and multiple guide posts 42 are fixedly installed on the bottom surfaces of the center plate 2 and the top plate 3. The guide posts 42 are located inside the corresponding guide sleeves 41 and are slidably connected to the guide sleeves 41. When the cylinder 4 drives the plate to rise and fall, the guide posts 42 and the guide sleeves 41 form a guiding limit to prevent the plate from deviating, thus achieving the stability of the lifting process and ensuring operational safety.

[0039] like Figure 1 and Figure 3 As shown, a limiting protrusion 31 is fixedly installed on the front side of the top plate 3, and a hook 5 is rotatably connected to the front side of the bottom plate 1. The end of the hook 5 is provided with a groove 50. The groove 50 is engaged with the limiting protrusion 31 for limiting operation after folding. A limiting plate 311 with an outer diameter larger than the inner diameter of the groove 50 is fixedly installed at the end of the limiting protrusion 31, so that the device can be limited by the hook 5 after being stored. The limiting plate 311 prevents the hook 5 from falling off, thus achieving a stable lock in the stored state and preventing the plate from being accidentally unfolded.

[0040] Specifically, a mobile battery box 15 is fixedly installed on the base plate 1. The mobile battery box 15 contains a mobile power source that can directly provide power to the cylinder 4 without the need for an external power source, thus improving the flexibility of use in the complex environment of the tea garden.

[0041] Finally, it should be noted that the cylinder 4, mobile power supply, corresponding air source, control system and external power supply involved in this utility model are all general standard parts or parts known to those skilled in the art. Their structure and principle can be known to those skilled in the art through technical manuals or conventional experimental methods. In the idle space of this device, all the above-mentioned electrical components, which refer to power elements, electrical components and the matching controller and power supply, are connected by wires. The specific connection method should refer to the working principle in this utility model. The electrical connection between each electrical component is completed in the order of operation. The detailed connection method is a technology known in the art.

[0042] When using the tea picking auxiliary support device adapted to different tea tree heights, hold the handle 17 on the base plate 1 and move the device to the side of the tea tree to be picked. The exposed hole 16 reduces the weight of the movement. According to the flatness of the ground, rotate the screw 11 in the threaded sleeve 10 at the bottom of the base plate 1 to adjust the height of the support pad 12 so that the base plate 1 is kept horizontal. The flared structure of the support pad 12 enhances the ground grip and ensures the stability of the device.

[0043] Secondly, during the height adjustment and operation phase, the cylinder 4 is powered by the mobile power supply in the mobile battery box 15. The cylinder 4 is started, and its telescopic shaft drives the center plate 2 and top plate 3 on the widened support 40 to rise and fall. The guide column 42 slides along the guide sleeve 41 to ensure stability. After adjusting to the appropriate position according to the height of the tea tree, the picking personnel stand on the top plate 3, and the mesh protection frame 30 provides safety protection.

[0044] Finally, in the transfer and storage stage, after the operation is completed, the cylinder 4 is activated to retract the center plate 2 and the top plate 3, and the hook 5 on the bottom plate 1 is rotated so that the slot 50 is locked on the limiting protrusion 31. The limiting plate 311 prevents it from falling off. The device is then laid down vertically, and the rollers 14 on the roller frame 13 contact the ground. The handle 17 can be pushed to easily transfer the device to the next work point.

[0045] The foregoing has shown and described the basic principles, main features, and advantages of this utility model.
