Description

Technical Field

[0001] This utility model relates to the field of walnut harvesting technology, and in particular to a walnut fresh fruit harvester. Background Technology

[0002] The outer layer of a fresh walnut is a fleshy, green husk that is thick and soft and contains abundant juice. Underneath the husk is the hard shell of the walnut, which is brownish-brown with irregular patterns on the surface and is hard in texture. Inside is the walnut kernel that people eat. The size of a fresh walnut varies depending on the variety, but it is generally about 3-6 centimeters in diameter.

[0003] When harvesting walnuts, workers often use simple tools to pull them apart from the tree. However, this process can tear the bark of the branches at the stem end, causing varying degrees of damage to the tree and hindering its growth and next year's yield. Furthermore, it can easily cause the green husk of the fresh walnuts to crack, making them more susceptible to external environmental factors during subsequent storage and transportation, thus affecting the appearance and quality of the fresh walnuts and reducing the overall harvesting quality. Summary of the Invention

[0004] The purpose of this invention is to provide a walnut fruit harvester that reduces damage to walnut trees during harvesting and also improves efficiency.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A walnut harvester includes a ring-shaped base with a net bag underneath. The top of the net bag is connected to the side wall of the ring-shaped base via multiple sets of rivets. A connector is connected to one side of the ring-shaped base via a mounting seat, and the mounting seat is detachably connected to the ring-shaped base via multiple sets of bolts. A threaded rod is provided at the end of the connector away from the ring-shaped base, and the threaded rod is threadedly connected to the end of a common telescopic rod. The length of the telescopic rod can be adjusted according to the growth height of different walnuts, making it suitable for different harvesting areas.

[0007] The top circumferential of the annular seat is provided with multiple baffles, and the multiple baffles are all inclined. Assembly blocks are respectively provided on the side walls of the multiple baffles, and grooves are provided on the assembly blocks. Connecting blocks are provided in the grooves. A reset mechanism is provided below the connecting blocks. A tool holder is installed at one end of the connecting block that extends outside the assembly block, and a blade is installed on the tool holder.

[0008] As a further preferred embodiment of this technical solution, a pin is provided in the groove of the assembly block, and a through groove is provided at one end of the connecting block extending into the groove, and the pin is rotatably connected to the connecting block through the through groove.

[0009] As a further preferred embodiment of this technical solution, the reset mechanism includes a spring, the top of which is connected to the lower surface of the connecting block, and the bottom of which is connected to a limiting block. The limiting block is disposed in a groove on the assembly block and is fixedly connected to the inner wall of the groove. The top of the limiting block is provided with an inclined surface, and the bottom of the spring is connected to the inclined surface at the top of the limiting block. When the spring contracts, it can reduce the radial deformation of the spring, keep the spring moving axially, and reduce the wear of related components.

[0010] As a further preferred embodiment of this technical solution, a guide plate is fixedly connected to the side wall of the blade holder, and the side walls of the guide plate are all set as arc surfaces. The arc surfaces contact the stalks of the fresh walnuts, which facilitates the sliding of the stalks above the blade holder and ensures that the stalks eventually move to the bottom of the blade.

[0011] As a further preferred embodiment of this technical solution, a cutting groove is provided on the side wall of the tool holder near the annular seat, and multiple protrusions are provided in the cutting groove; the multiple protrusions provided in conjunction with the cutting groove on the tool holder can realize the quick disassembly of the blade, and the blades in the corresponding positions can be replaced according to the actual use, which is convenient for maintenance.

[0012] As a further preferred embodiment of this technical solution, the blade is inclined, and the end of the blade away from the blade holder is provided with multiple sets of serrations. The bottom of the blade extends towards the center of the annular seat, and the blade is set with a large inclination angle relative to the adjacent baffle. During the harvesting process, the blade can easily cut the fruit stem. With the force applied by pulling, the harvesting of fresh walnuts can be completed quickly. The side wall of the blade can separate the broken fruit stem from the branch, thereby reducing the impact of the trajectory of the fresh walnuts falling when the branch rebounds.

[0013] This invention offers the following advantages: The design of the annular seat and net bag allows for the effective collection of fallen walnuts without damaging the trees. The inclined baffle helps guide the walnuts into the net bag, improving harvesting efficiency. The bolted connection between the annular seat and the connector makes the entire device easy to assemble and disassemble, facilitating carrying and storage. The threaded rod design allows for adjustment or replacement of the handle as needed. Multiple protrusions in the blade groove on the blade holder enable quick blade assembly and disassembly, improving work efficiency and facilitating blade cleaning and maintenance. The reset mechanism, including a spring and a limit block, ensures the connecting block automatically resets when not subjected to external force, preventing accidental damage to the equipment or user. Simultaneously, the serrations on the blade help to cut fruit branches more easily, while the curved design of the guide plate reduces scratches on the fruit trees during operation. The combination of the pin and through groove allows the connecting block to rotate within a certain range, increasing the flexibility of blade operation and adapting to fruit harvesting needs at different angles and positions. The detachable connection and safe blade fixing mechanism, along with the inclined design at the top of the limit block, effectively enhance safety during use. Attached Figure Description

[0020] 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.

[0021] This utility model provides a technical solution: such as Figure 1 As shown, a walnut harvester includes a ring seat 1, a net bag 2 is provided below the ring seat 1, the top of the net bag 2 is connected to the side wall of the ring seat 1 by multiple sets of rivets, a connector 3 is connected to one side of the ring seat 1 by a mounting base 31, and the mounting base 31 is detachably connected to the ring seat 1 by multiple sets of bolts, and a threaded rod 32 is provided at the end of the connector 3 away from the ring seat 1, which is threadedly connected to the end of a common telescopic rod, so that the length of the telescopic rod itself can be adjusted according to the growth height of different walnuts, and it is suitable for different harvesting areas.

[0022] In addition, multiple baffles 4 are arranged circumferentially on the top of the annular seat 1, and all baffles 4 are inclined. Assembly blocks 5 are respectively arranged on the side walls of the multiple baffles 4, and the assembly blocks 5 have grooves. A connecting block 51 is arranged in the groove, and a pin is arranged in the groove. The end of the connecting block 51 extending into the groove has a through groove 54. The pin is rotatably connected to the connecting block 51 through the through groove 54. When the fruit stem presses the knife holder 6 downward, the connecting block 51 will rotate around the pin as the axis, causing the spring 52 below to contract. When the fruit stem separates from the knife holder 6, the elasticity of the spring 52 can drive the knife holder 6 and the blade 7 to return to their original positions for subsequent cutting.

[0023] like Figure 2 As shown, a reset mechanism is provided below the connecting block 51. The reset mechanism includes a spring 52. The top of the spring 52 is connected to the lower surface of the connecting block 51, and the bottom of the spring 52 is connected to a limit block 53. The limit block 53 is set in a groove opened on the assembly block 5, and the limit block 53 is fixedly connected to the inner wall of the groove. The top of the limit block 53 is provided with an inclined surface, and the bottom of the spring 52 is connected to the inclined surface at the top of the limit block 53. When the spring 52 contracts, it can reduce the radial deformation of the spring 52, keep the spring 52 moving axially, and reduce the wear of related components.

[0024] like Figure 3As shown, a blade holder 6 is installed at one end of the connecting block 51 extending outside the assembly block 5. A guide plate 61 is fixedly connected to the side wall of the blade holder 6, and the side walls of the guide plate 61 are all set as arc surfaces. The arc surfaces contact the stem of the fresh walnut, which facilitates the sliding of the stem above the blade holder 6 and ensures that the stem eventually moves to the bottom of the blade 7. A blade groove 62 is opened on the side wall of the blade holder 6 near the annular seat 1, and multiple protrusions are provided in the blade groove 62. The multiple protrusions provided in conjunction with the blade groove 62 on the blade holder 6 can realize the quick disassembly of the blade 7. The protrusions are made of rubber material, which can increase the friction between the blade 7 and the blade groove 62 and limit the edge of the blade 7. The blade 7 in the corresponding position can be replaced according to the actual use, which is convenient for maintenance.

[0025] like Figure 4 As shown, the blade holder 6 is equipped with a blade 7, which is inclined and has multiple sets of serrations 71 at the end away from the blade holder 6. It should be noted that the bottom of the blade 7 extends towards the center of the annular seat 1, and the blade 7 has a large angle relative to the adjacent baffle 4. During harvesting, the blade 7 can easily cut the fruit stalk, and with the pulling force, the harvesting of fresh walnuts can be completed quickly. Furthermore, the sidewall of the blade 7 can separate the broken fruit stalk from the branch, thereby reducing the impact of the branch's rebound on the trajectory of the fresh walnuts falling.

[0026] This utility model provides a walnut harvester. In use, the threaded rod 32 on the connector 3 is threadedly connected to an external telescopic rod. The length of the telescopic rod is adjusted to accommodate walnuts at different heights. During harvesting, depending on the angle at which the walnuts hang from the branch, two adjacent baffles 4 are moved behind the walnuts to ensure they remain within the lower net 2, preventing them from falling to the ground and causing damage. The distal end of the annular seat 1 is slightly raised, at which point the guide plate 61 above the blade holder 6 engages with the walnut stem. When the fruit stem is continuously moved downwards, the blade holder 6 moves as a whole. At this time, the spring 52 is in a contracted state. Finally, the fruit stem will move to the bottom of the baffle 4 through the gap between the blade holder 6 and the adjacent baffle 4. At this time, the spring 52 extends, driving the blade holder 6 to move upwards. The fruit stem separates from the blade holder 6 and is located below the blade 7. Through the force applied by the harvester, the serrations 71 at the end of the blade 7 can cut the fruit stem of the fresh walnut, forming a relatively regular fracture surface, reducing the damage to the tree. Finally, the fresh walnut will fall into the net bag 2 below for collection, making it convenient for workers to continue harvesting.

[0027] The various embodiments in this specification are described in a related manner. The same or similar parts between the various embodiments can be referred to each other. Each embodiment focuses on describing the differences from other embodiments.

[0028] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model are included within the scope of protection of this utility model.
