Description

Technical Field

[0001] This utility model relates to the field of agricultural harvesting equipment technology, and in particular to an adjustable collection device for harvesting fruits and vegetables. Background Technology

[0002] With the continuous advancement of agricultural technology, the scale of fruit and vegetable cultivation is expanding, which places higher demands on the efficiency and quality of the harvesting process. The traditional manual harvesting method is labor-intensive and inefficient, making it difficult to meet the needs of modern large-scale agricultural production.

[0003] As a result, mechanized harvesting devices have emerged in the market to replace manual operations. The application of these harvesting devices has improved the overall harvesting speed to some extent. However, the design of existing harvesting devices has shortcomings. The harvesting head structure of many harvesting devices is fixed, and the working angle and direction cannot be effectively adjusted. When fruits and vegetables grow in areas where branches and leaves are obstructed or in special locations, the fixed harvesting head is difficult to reach the target, resulting in missed harvesting or unnecessary damage to the plants during the harvesting process.

[0004] In addition, some harvesting devices lack stability in their clamping mechanisms when holding fruits and vegetables. Shaking or inaccurate control of clamping force during operation can cause squeezing or scratching of the fruits and vegetables, affecting their quality and commercial value. More importantly, existing harvesting devices lack a reliable collection function after the cutting action is completed. Fruits and vegetables fall directly to the ground from a height, causing serious impact damage and requiring a second manual bend to pick them up. This not only reduces work efficiency but also increases additional labor costs.

[0005] Therefore, this utility model proposes an adjustable collection device for fruit and vegetable harvesting to address the shortcomings of existing technologies. Utility Model Content

[0006] In view of the problems of existing fruit and vegetable harvesting devices, such as fixed harvesting head angle, difficulty in adapting to different harvesting needs, insufficient stability during harvesting, and lack of effective collection function, this utility model aims to provide an adjustable collection device for fruit and vegetable harvesting with an improved structure that can effectively solve the above problems.

[0007] This utility model provides an adjustable collection device for fruit and vegetable harvesting, including a harvesting pole, a retractable net, and a connecting plate rotatably connected to the top of the harvesting pole; it also includes an adjustment mechanism set on the harvesting pole, a hydraulic press, a connecting platform, a first rotating column, a connecting rod, a claw, a blade, a fixing frame, a support column, a connecting column, a second rotating column, a retractable net, and a collection mechanism set below the claw on the connecting plate.

[0008] The adjustment mechanism includes a handle that is connected to the rotating column via a transmission column and bevel gear one, bevel gear two, and a retractable net adjustment mechanism, which also has a locking block, a locking groove, and a sliding groove for locking the transmission column.

[0009] Furthermore, the rotating column three is fixedly connected to the connecting plate to drive the connecting plate to rotate; the hydraulic press drives the connecting platform, and the connecting platform expands by linking multiple claws through the rotating column one and the connecting rod; the fixed frame, support column and connecting column constitute a frame for supporting the claws, and the connecting column is rotatably connected to the claws through the rotating column two; the blade is set on the top of the claws; the collecting mechanism is set below the claws to receive the harvested fruits.

[0010] Preferably, the handle is fixedly connected to one end of the transmission column, and the other end of the transmission column is fixedly connected to the second bevel gear. The second bevel gear meshes with the first bevel gear, and the top surface of the first bevel gear is fixedly connected to the bottom of the third rotating column.

[0011] Preferably, one end of the rotating column is rotatably connected to the inner wall of the connecting platform, and the other end of the rotating column is rotatably connected to the connecting rod.

[0012] Preferably, the middle part of the claw is rotatably connected to the outer wall of the connecting column via a rotating column 2.

[0016] Preferably, the collection mechanism is a retractable net.

[0017] This utility model has the following beneficial effects: 1. This utility model solves the problems of fixed angle of the picking device in the prior art, which makes it difficult to adapt to the picking needs of fruits and vegetables in different positions, and the fruits and vegetables are damaged due to instability during the picking process. It can flexibly adjust the angle of the picking head and make it easy to aim at the target. The locking mechanism ensures that the picking process is stable and reliable, thereby improving the picking efficiency and reducing the fruit and vegetable damage rate. 2. This utility model solves the problems of insufficient clamping force and poor stability of the picking device in the prior art, as well as the secondary damage caused by the direct fall of the fruit after picking and the inconvenience of collection. It adopts a hydraulic press to drive a multi-link structure linkage claw for expansion and clamping, and sets a collection mechanism below the claw.

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0021] Example: Please refer to Figures 1 to 4 This utility model provides an adjustable collection device for fruit and vegetable harvesting, including a harvesting rod 1. The harvesting rod 1 is provided with an adjustment mechanism 2. The adjustment mechanism 2 includes a handle 205. The handle 205 is fixedly connected to one end of a transmission column 204. The other end of the transmission column 204 is fixedly connected to a bevel gear 203. The outer wall of the bevel gear 203 meshes with the outer wall of the bevel gear 202. The bottom of a rotating column 201 is fixedly connected to the middle of the top surface of the bevel gear 202. A sliding groove 207 is provided on the outer wall of the harvesting rod 1. A locking block 208 is slidably provided in the sliding groove 207. A locking groove 206 is provided at one end of the sliding groove 207. The locking block 208 can slide and lock into the locking groove 206 to abut and fix the transmission column 204.

[0022] A connecting plate 3 is rotatably connected to the top of the picking rod 1. The top of the rotating column 201 is fixedly connected to the bottom of the connecting plate 3. A hydraulic press 4 is fixedly connected to the top of the connecting plate 3. The output end of the hydraulic press 4 presses against the connecting platform 5. Multiple rotating columns 6 are rotatably connected to the inner wall of the connecting platform 5. The rotating columns 6 are rotatably connected to the connecting rod 7. The other end of the connecting rod 7 is rotatably connected to the claw 8. Multiple claws 8 are arranged in a circular array. A blade 13 is provided on the top of the claw 8. A fixing frame 9 is also fixedly connected to the top of the connecting plate 3. A support column 10 is fixedly connected to the top of the fixing frame 9. The top of the support column 10 is fixedly connected to the bottom of the connecting column 12. The outer wall of the connecting column 12 is rotatably connected to the middle of the claw 8 through a rotating column 21. A retractable net-shaped collection mechanism is also provided below the multiple claws 8.

[0023] Please refer to Figure 1 and Figure 2 The hydraulic press 4 provides power to the harvesting mechanism. The hydraulic press 4 is vertically set on the top of the connecting plate 3. The piston rod of the hydraulic press 4 pushes upward against the bottom of the connecting platform 5 to ensure that the connecting platform 5 can move upward stably under the action of the hydraulic press 4. The function of the hydraulic press 4 is to provide driving force for the opening and closing of the claw 8. Multiple rotating columns 6 are rotatably connected to the inner wall of the connecting platform 5. These rotating columns 6 are radially distributed around the axis of the connecting column 12. The other end of the rotating column 6 is rotatably connected to one end of the connecting rod 7. The lower end of the connecting rod 7 is rotatably connected to the upper part of the claw 8. In the assembled state, when the connecting platform 5 moves upward, the claw 8 will expand outward to clamp the fruit through the linkage of the rotating columns 6 and the connecting rod 7, ensuring the stability and strength of the claw 8 when clamping the fruit and effectively preventing the fruit from falling off.

[0024] The middle part of the claw 8 is rotatably connected to the outer wall of the connecting column 12 via the rotating column 2 11. The rotating column 2 11 ensures that the claw 8 remains stable during expansion and contraction, preventing shaking. The connecting column 12 serves as the central axis of the harvesting mechanism. The bottom of the fixing frame 9 is fixed to the top of the connecting plate 3, the support column 10 is fixed to the top of the fixing frame 9, and the bottom of the connecting column 12 is fixed to the top of the support column 10. The connection of the fixing frame 9, the support column 10, and the connecting column 12 ensures the stability and rigidity of the entire harvesting mechanism. The top of the claw 8 is equipped with a blade 13, which is located on the upper inner side of the claw 8. This blade 13 is used to easily and quickly cut the fruit off the branch after the claw 8 has gripped it.

[0025] Below the multiple claws 8, there is a retractable net-like collection mechanism. The collection mechanism is fixed to the connecting plate 3 by a bracket. It can catch the harvested fruits and vegetables, prevent them from falling directly to the ground and causing damage, and achieve the initial collection of the fruits and vegetables.

[0026] In a preferred embodiment, to make the transmission of the adjustment mechanism 2 more compact and accurate, the handle 205 drives the transmission column 204 to rotate through a fixed connection. The other end of the transmission column 204 also drives the bevel gear 203 to rotate through a fixed connection. The bevel gear 203 is connected to the outer wall of the bevel gear 202 in a meshing manner to transmit rotational motion. The bottom of the rotating column 201 is fixedly connected to the middle of the top surface of the bevel gear 202, ensuring that the rotational torque from the handle 205 to the rotating column 201 can be transmitted accurately and efficiently.

[0027] As another preferred embodiment, in order to achieve reliable opening and closing of the claw 8, one end of the rotating column 6 is rotatably connected to the inner wall of the connecting platform 5, the other end of the rotating column 6 is rotatably connected to one end of the connecting rod 7, and the lower end of the connecting rod 7 is rotatably connected to the upper part of the claw 8, so as to convert the linear motion of the connecting platform 5 into the arc opening and closing motion of the claw 8, thus ensuring the stable opening and closing of the claw 8 during the picking process.

[0028] In another preferred embodiment, in order to improve the overall stability of the picking mechanism, the middle part of the claw 8 is rotatably connected to the outer wall of the connecting column 12 through the rotating column 2 11. The rotating column 2 11 serves as the rotation fulcrum of the claw 8, effectively supporting the claw 8 and preventing unnecessary shaking when clamping or cutting fruits, thereby ensuring the accuracy and stability of the picking process.

[0029] In another preferred embodiment, in order to ensure the structural strength and rigidity of the harvesting mechanism, the bottom of the fixing frame 9 is firmly fixed to the top of the connecting plate 3, the support column 10 is also firmly fixed to the top of the fixing frame 9, and the bottom of the connecting column 12 is further firmly fixed to the top of the support column 10, forming a stable support frame to provide solid support for the hydraulic harvesting mechanism and the claw 8.

[0030] As another preferred embodiment, in order to clarify the driving method of the hydraulic press 4, the piston rod of the hydraulic press 4 presses upward against the bottom of the connecting platform 5, and the direct force of the piston rod is precisely applied to the connecting platform 5, ensuring the effective transmission of hydraulic power and driving the movement of the claw 8.

[0031] As another preferred embodiment, in order to make picking and cutting more convenient, the blade 13 is set on the upper inner side of the claw 8, so that the blade 13 can quickly complete the cutting action after the claw 8 holds the fruit, thereby improving the picking efficiency.

[0032] As another preferred implementation method, in order to effectively collect the harvested fruits and vegetables, the collection mechanism is specifically embodied as a retractable net bag. The retractable net bag is set below the claw 8. When the fruits and vegetables are cut and fall, the retractable net bag can catch them in time, preventing them from falling to the ground, reducing damage to the fruits and vegetables, and facilitating subsequent centralized processing.

[0033] Working principle: When the picking angle needs to be adjusted to handle fruits that are difficult to grip, the operator turns the handle 205 on the adjustment mechanism 2. The handle 205 drives the transmission column 204 and the fixedly connected bevel gear 203 to rotate synchronously. Since the bevel gear 203 is meshed with the bevel gear 1 202, the rotation of the bevel gear 203 drives the bevel gear 1 202 to rotate, which in turn drives the rotating column 3 201, which is fixedly connected to the bevel gear 1 202, to rotate. Since the top of the rotating column 3 201 is fixedly connected to the connecting plate 3, the connecting plate 3 drives the entire picking mechanism to rotate, thereby realizing the flexible adjustment of the picking angle. After adjusting to the appropriate angle, the operator slides the locking block 208 along the sliding groove 207 into the locking groove 206. The locking block 208 locks the transmission column 204 to prevent the transmission column 204 from rotating accidentally, thus ensuring the stability of the picking process. When harvesting fruits and vegetables, the hydraulic press 4 is started. The piston rod of the hydraulic press 4 pushes the connecting platform 5 upward. During the upward movement of the connecting platform 5, the rotating column 6 pushes the connecting rod 7 to move. Since the other end of the connecting rod 7 is rotatably connected to the claw 8, the coordinated action of multiple connecting rods 7 will cause multiple claws 8 to expand outward synchronously, thereby opening and clamping the target fruits and vegetables. The middle part of the claw 8 is rotatably connected to the connecting column 12, which serves as the center of stability, through the rotating column 11. With the joint support of the fixed frame 9 and the support column 10, the stability and reliability of the claw 8 during the clamping process are ensured. After the claw 8 clamps the fruits and vegetables, the blade 13 at the top of the claw 8 cuts the stem of the fruits and vegetables. The fruits and vegetables fall into the retractable net-like collection mechanism that has been unfolded below, thus completing the harvesting and collection of fruits and vegetables. Through the coordinated action of the adjusting mechanism 2 and the hydraulic harvesting mechanism, the problems of difficult angle adjustment, unstable harvesting, easy damage to fruits and vegetables, and lack of collection function in the existing technology are solved.
