Abstract
Description
Technical Field
[0001] This application relates to the field of agricultural implements, specifically to a leaf-cutting and fruit-picking device suitable for palm trees. Background Technology
[0002] Palm trees are tall, single-trunk, upright plants with a cylindrical trunk, typically exceeding 5 meters in height. They are unbranched, with large leaves concentrated at the top of the trunk, mostly palmately lobed or pinnately compound. Manually pruning leaves and harvesting fruit from palm trees presents significant challenges. To address the difficulties and risks associated with manual pruning and harvesting, fruit-harvesting equipment has been developed.
[0003] However, current fruit-picking equipment is bulky, complex, and expensive. Furthermore, current equipment often uses scissor-like or saw-like methods, which, given the growth characteristics of palm tree branches and leaves, often result in blade jamming or slippage. This fails to solve the problem of fast and effective leaf pruning and fruit picking, and also does not adequately address the issue of blade movement at heights during pruning and fruit picking, thus hindering the practical mechanization of these processes. Utility Model Content
[0004] To solve the above-mentioned technical problems, this application provides the following technical solution:
[0005] This application provides a leaf-cutting and fruit-picking device suitable for palm trees, comprising:
[0006] Connection components; and
[0007] The cutter assembly has a pivot seat on its outer surface. The cutter assembly is pivotally connected to the connecting assembly through the pivot seat, so that the cutter assembly can swing relative to the connecting assembly.
[0008] The cutting assembly includes: a drive rail, a power unit, and a cutting tool; the drive rail has an arc-shaped slide rail, the power unit is slidably connected to the slide rail, and the power unit can slide along the trajectory direction defined by the slide rail;
[0009] The cutting tool is mounted on the power output end of the power unit, and under the drive of the power unit, the cutting tool reciprocates along a straight line.
[0010] In one embodiment, the cutting tool has a first cutting portion and a second cutting portion, which are disposed on both sides of the cutting tool.
[0011] In one embodiment, the second cutting portion is concave arc-shaped.
[0012] In one embodiment, the cutter is arc-shaped and has an inner arc surface that conforms to the side of the palm tree.
[0013] In one embodiment, the cutting tool is connected to the power unit via a detachable linkage.
[0014] In one embodiment, a quick-release seat is provided on the end of the connecting rod near the cutter.
[0015] In one embodiment, the connecting assembly is equipped with a rotating motor, which drives the cutting assembly to swing around the pivot seat as the rotation center.
[0016] In one embodiment, a gear is mounted on the pivot, and the rotating motor is driven by the gear.
[0017] In one embodiment, a sliding block is slidably connected to the slide rail, and the sliding block is connected to a power unit. The sliding block is driven by a driver to slide on the slide rail.
[0018] In one embodiment, a base is mounted on the bottom of the slide rail, the base having a side surface arranged concentrically with the slide rail, and teeth are provided on the side surface.
[0019] The driver is mounted on the sliding block, and the driver meshes with the teeth through a transmission gear.
[0020] This application has at least the following beneficial effects:
[0021] In this application, the power unit and the cutter slide along the slide rail in an arc direction. The arc-shaped sliding track of the power unit and the cutter is set concentrically with the fruit tree. The power unit and the cutter can make circular motion around the tree. The power unit drives the cutter to move up and down reciprocally. The cutter quickly cuts the leaves and fruits of the palm tree, reducing the risk of the cutter getting stuck or slipping.
[0022] In this application, since the connecting component connected to the cutting assembly can also be connected to the transfer device, the transfer device drives the cutting assembly to achieve position transfer, which facilitates the transfer of the blade at high altitude. First, this leaf-cutting and fruit-picking device can avoid workers climbing to high altitudes to prune leaves and pick fruits, ensuring the personal safety of workers. Second, the transfer of the blade at high altitude can cause the blade to quickly approach the top of the palm tree, thereby reducing the interval time during the transfer process and improving the efficiency of the cutting work.
[0023] In this application, the cutting assembly is pivotally connected to the connecting assembly via a pivot seat, allowing the cutting assembly to swing slightly relative to the connecting assembly. This facilitates small-range adjustments to the relative position of the cutting assembly and the palm tree, reducing the time spent adjusting the position of the cutting assembly after transfer and further improving the efficiency of the cutting work.

[0047] The embodiments of this application are described in detail below with reference to the accompanying drawings.
[0048] Reference Figure 1 , 3 As shown, some embodiments of this application provide a leaf-cutting and fruit-picking device suitable for palm trees, including a cutter assembly 1 and a connecting assembly 2. The connecting assembly 2 is used to connect the cutter assembly 1 to a transfer device, which can be a vehicle. The vehicle tows the cutter assembly 1 to facilitate switching between different palm trees or at different angles on the palm trees. The cutter assembly 1 is rotatably connected to the connecting assembly 2. The cutter assembly 1 includes a drive rail 11, a power unit 12, and a cutter 13. The drive rail 11 has a built-in sliding seat 112, which includes an arc-shaped slide rail 1122. The power unit 12 is slidably connected to the slide rail 1122, and the cutter 13 is mounted on the power output end of the power unit 12.
[0049] Specifically, the rotation of the cutting blade assembly 1 involves adjusting the center position of the arc-shaped slide rail 1122 so that the center of the slide rail 1122 coincides with the center of the palm tree, meaning the slide rail 1122 and the palm tree are concentrically positioned. In this case, the movement of the power unit 12 and the cutter 13 along the slide rail 1122 is equivalent to rotation around the palm tree, allowing the power unit 12 to drive the cutter 13 to cut leaves and fruit around the palm tree. It is understood that because the slide rail 1122 is arc-shaped, the angle of rotation of the power unit 12 and the cutter 13 around the palm tree along the slide rail 1122 does not exceed 360°. Therefore, this adjustment facilitates the concentric positioning of the slide rail 1122 and the palm tree.
[0050] Preferably, the angle of the arc-shaped slide rail 1122 does not exceed 180° (to facilitate the entry of the palm tree from the opening of the arc-shaped slide rail 1122 so that the center of the palm tree and the center of the arc-shaped slide rail 1122 are aligned at the same point). Therefore, it is necessary to adjust the angle of the leaf-cutting and fruit-picking device relative to the palm tree by dragging the cutter assembly 1 by a vehicle so that the cutter 13 can rotate around a palm tree to perform leaf-cutting and / or fruit-cutting actions.
[0051] The cutter assembly 1 is rotatably connected to the connecting assembly 2. Specifically, the connecting assembly 2 is equipped with a rotary motor 23, which drives the cutter assembly 1 to rotate relative to the connecting assembly 2. For more details, see [link to details]. Figure 2 As shown, and in combination Figure 4 As shown, the connecting assembly 2 includes a connecting rod 21, and the cutter assembly 1 is provided with a pivot seat 14. The pivot seat 14 is located on the drive rail 11 and is pivotally connected to one end of the connecting rod 21. A gear 15 is installed on the pivot seat 14, and the rotating motor 23 is driven by the pivot seat 14 through the meshing of the gear 15, which improves the stability of the rotating motor 23 driving the pivot seat 14 to rotate.
[0052] More specifically, a support base 22 is mounted on one end of the connecting rod 21. The support base 22 is N-shaped and connected to the connecting rod 21, forming a hollow space within it. A rotary motor 23 is mounted on the support base 22, and the rotating shaft of the rotary motor 23 extends into the hollow space. The gear 15 on the pivot seat 14 is also located within the hollow space, allowing the gear on the rotary motor 23 to mesh and transmit power with the gear 15 within the hollow space. Driven by the rotary motor 23, the cutter assembly 1 rotates relative to the connecting rod 21.
[0053] In this design, the power unit 12 drives the cutter 13 to reciprocate along a straight line. By using the impact force of the cutter 13 on the leaves and / or fruits of the palm tree, the power unit 12 drives the cutter 13 to cut the leaves and / or fruits, thus avoiding the problem of cutter jamming or slippage. More specifically, the straight line in which the cutter 13 moves is inclined relative to the axis of the palm tree. As the cutter 13 gradually moves away from the power unit 12, it gradually moves closer to the palm tree until it approaches the top of the palm tree, at which point the first cutting portion 131 of the cutter 13 is in contact with the side of the palm tree. For example, the power unit 12 can be an electric drill, and a reciprocating saw adapter head can be installed on the output end of the drill to convert rotation into linear reciprocating motion.
[0054] Furthermore, combined Figure 7 As shown, the cutter 13 has a first cutting portion 131 and a second cutting portion 132, which are arranged opposite to each other. The first cutting portion 131 is located at the front end of the cutter 13, while the second cutting portion 132 is located at the rear end of the cutter 13. When the cutter 13 pushes towards the top of the palm tree, the first cutting portion 131 impacts the leaves and / or fruits on the palm tree. When the cutter 13 retracts, the second cutting portion 132 hooks and pulls the roots of the remaining leaves and / or fruits, thereby improving the cutting effect of the leaf and fruit cutting device. In this design, the second cutting portion 132 and the power output end of the power unit 12 are located on the same side of the cutter 13 to reduce torque and thus reduce deformation stress, thereby reducing the wear caused by the reaction force of leaves and / or fruits on the cutter 13. More specifically, the second cutting portion 132 is an inwardly concave arc-shaped cutting portion. By forming a hook-like structure on the cutter 13, the second cutting portion 132 can more easily hook and pull the roots of leaves and / or fruits.
[0055] In this design, the blade 13 is elongated and positioned tangentially to the palm tree. The cutting point of the blade 13 is a single point, allowing it to cut leaves and / or fruits along a straight path on the palm tree in a single pass. In another embodiment, the blade 13 is arc-shaped, with its inner arc surface fitting against the side of the palm tree. In this case, the blade 13 cuts leaves and / or fruits along the vertical path of its vertical sweeping surface, resulting in a larger number of leaves and / or fruits cut in a single pass and higher efficiency.
[0056] Furthermore, the cutter 13 and the power unit 12 are connected by a connecting rod 16. One end of the connecting rod 16 is connected to the side of the cutter 13 where the second cutting section 132 is located, while the other end of the connecting rod 16 is connected to the power output end of the power unit 12. In a specific embodiment, the installation direction of the connecting rod 16 is consistent with the aforementioned straight line direction, allowing the cutter 13 to move in a direction inclined relative to the axis of the palm tree. In this solution, the connecting rod 16 can detachably connect the cutter 13 and the power unit 12. For different tree heights, the connecting rod 16 can be changed to different lengths to achieve punching of palm trees of different heights, thus completing the operation.
[0057] In this design, the blade 13 is supported at a high position by the connecting rod 16. When the leaf-cutting and fruit-picking device is moved, the blade 13 remains at a high position. After the move, the blade 13 is still close to the top of the palm tree, allowing it to quickly cut the leaves and / or fruits of the palm tree. Moving the blade 13 at a high position effectively improves work efficiency.
[0058] Furthermore, since the aforementioned cutting tool 13 needs to be adapted to palm trees of different diameters, the size and model of the cutting tool 13 vary. Additionally, the cutting tool 13 inevitably experiences wear during the punching process. To achieve quick replacement of the cutting tool 13, a quick-release seat 161 is provided on the end of the connecting rod 16 near the cutting tool 13. The cutting tool 13 is mounted on the quick-release seat 161 for quick assembly and disassembly. For example, the quick-release seat 161 includes a clamping slot for holding the cutting tool 13, and the width of the clamping slot is adjustable. During disassembly, the width of the clamping slot increases, and after replacing the cutting tool 13, the width of the clamping slot decreases to clamp the cutting tool 13 securely. Alternatively, for example, a screwdriver with replaceable bits, with various models of the tool 13 having the same limiting post, and a mounting hole on the quick-release base 161 that is the same shape as the limiting post. The tool 13 is installed on the quick-release base 161 by inserting the limiting post into the mounting hole. The limiting post or mounting hole is magnetic, and the limiting post and mounting hole prevent the tool 13 from separating from the quick-release base 161 by adsorption.
[0059] In some embodiments of this application, reference is made to Figure 5 , 6 As shown, the drive rail 11 also includes a housing 111 and a connecting seat 113. In this design, the sliding seat 112 is located inside the housing 111, while the connecting seat 113 is located outside the housing 111, and the power unit 12 is mounted on the connecting seat 113. The sliding seat 112 includes a sliding block 1123, which is slidably connected to the slide rail 1122. The sliding block 1123 and the connecting seat 113 are connected by a column 114, and both the sliding block 1123 and the connecting seat 113 move along the direction defined by the slide rail 1122.
[0060] To enable the sliding block 1123 and the connecting seat 113, located inside and outside the outer casing 111, to move together, the sliding block 1123 and the connecting seat 113 are connected by a column 114. The outer casing 111 has a groove 1111 adapted to the slide rail 1122, and the column 1111 passes through the groove 1111. Specifically, the groove 1111 is an arc-shaped groove, and the groove 1111 and the slide rail 1122 are arranged concentrically, or the groove 1111 and the slide rail 1122 have the same shape.
[0061] Furthermore, the sliding block 1123 is driven by a driver 1124 to slide on the slide rail 1122. Under the drive of the driver 1124, the sliding block 1123 slides along the direction defined by the slide rail 1122. Specifically, the sliding seat 112 also includes a base 1121, the slide rail 1122 is mounted on the base 1121, the slide rail 1122 and the base 1121 are arranged vertically, and the slide rail 1122 and the base 1121 are fixedly connected.
[0062] The base 1121 has a side surface concentrically arranged with the slide rail 1122, and teeth are evenly distributed on the side surface. The driver 1124 is mounted on the sliding block 1122, and the driver 1124 meshes with the teeth through a transmission gear 1125. Driven by the driver 1124, the sliding block 1122 slides along the arc direction defined by the slide rail 1122.
[0063] The above embodiments are used to further illustrate this application, but do not limit this application to these specific implementations. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be understood as falling within the protection scope of this application.
