Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, and in particular to a soil-carrying seedling extractor for transplanting vegetables. Background Technology

[0002] In large-scale vegetable cultivation, the quality of seedling removal with soil attached during transplanting directly affects seedling survival rate and subsequent growth. Currently, seedling removal operations in the industry face multiple bottlenecks: On the one hand, manual seedling removal is labor-intensive and inefficient, making it difficult to adapt to the needs of agricultural mechanization. Uneven soil attachment can easily damage the root system, leading to low survival rates after transplanting. On the other hand, existing semi-automatic seedling removal equipment has significant defects, such as insufficient precision in the transmission structure, making moving parts prone to radial misalignment, causing seedling position deviations and seedling compression damage. Simultaneously, soil debris and weeds can easily intrude into the movement gaps, causing jamming and reducing equipment operational stability. Furthermore, most equipment lacks convenient maintenance structures; component repair requires disassembling the entire machine, which is cumbersome and affects work progress. The high resistance of the seedling removal components into the soil not only exacerbates equipment wear but also easily leads to vegetable root breakage and substrate scattering, further restricting transplanting quality.

[0003] Therefore, we propose a soil-carrying seedling extractor for agricultural vegetable transplanting. Utility Model Content

[0004] The main purpose of this utility model is to provide a soil-carrying seedling extractor for transplanting vegetables in agriculture. To prevent the drawbacks of manual seedling extraction and the problems of transmission, maintenance, and soil insertion of existing semi-automatic equipment, this utility model improves seedling extraction efficiency, seedling survival rate, equipment stability and convenience through technological innovation, reduces losses, and enhances the benefits of large-scale vegetable planting and transplanting. It can effectively solve the problems in the background technology.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A seedling extractor with soil attached for transplanting agricultural vegetables includes a circular fixed frame, movable wheels, and a seedling extractor body. The seedling extractor body is fixedly connected to the bottom end of the movable wheels, which are embedded in the circular fixed frame. Both the circular fixed frame and the movable wheels have an opening for the agricultural vegetables to pass through. A protective box is fixedly connected to the outer circumference of the circular fixed frame, and a motor is provided at the top of the protective box to drive the movable wheels to rotate around the axis of the circular fixed frame.

[0007] By adopting the above technical solution, the operator first moves the device to the vegetable planting area where the seedlings are to be harvested, ensuring that the openings on the circular fixed frame and the movable wheels are precisely aligned with the target vegetable seedlings, so that the seedlings can pass through the openings smoothly without being squeezed or damaged. Then, the motor at the top of the protective box is started, and the motor drives the movable wheels to rotate around the axis of the circular fixed frame. When the movable wheels rotate, they drive the seedling harvester body fixedly connected to the bottom to move synchronously. The seedling harvester body cuts into the soil at the root of the vegetable seedling as the movable wheels rotate, realizing the operation of harvesting seedlings with soil.

[0008] Furthermore, the circular fixing frame is provided with an annular mounting groove, the movable wheel is embedded in the mounting groove, and the inner circumferential surface of the movable wheel is slidably connected to the inner circumferential surface of the mounting groove.

[0009] By adopting the above technical solution, when the motor drives the movable wheel to rotate around the axis of the circular fixed frame, the movable wheel will slide along the inner circumferential surface of the annular mounting groove on the circular fixed frame. The mounting groove provides a stable motion trajectory for the movable wheel, effectively limiting the radial offset of the movable wheel during rotation, ensuring that the seedling picker body always moves along the preset path, improving the accuracy of the seedling picking position, and avoiding seedling picking errors or damage to vegetable seedlings due to the offset of the movable wheel.

[0010] Furthermore, the movable wheel is provided with an external gear ring, and the motor output shaft extends into the inner wall of the protective box and is fixedly installed with a gear. The gear extends into the mounting groove and meshes with the external gear ring of the movable wheel.

[0011] By adopting the above technical solution, when the movable wheel needs to rotate to drive the seedling extractor body, the motor is started. The motor's output shaft drives the gear, which extends into the protective box and is wall-mounted, to rotate. Because the gear extends into the mounting slot and meshes with the external gear ring on the movable wheel, the gear's rotation drives the movable wheel to rotate synchronously through tooth transmission. This gear meshing transmission method can precisely transmit power, ensuring the stability of the movable wheel's rotation speed and angle, thereby making the seedling extractor body's seedling-taking action rhythm controllable, improving seedling-taking efficiency and the integrity of seedlings taken with soil.

[0012] Furthermore, the bottom of the circular fixing frame is provided with a detachable limiting member, and the limiting member is ring-shaped, and the lower end face of the seedling taker body is provided with an inclined surface.

[0013] By adopting the above technical solution, the annular limiting component at the bottom of the circular fixed frame can be disassembled or installed according to the needs of seedling collection and device maintenance. When the limiting component is installed, it acts as a bottom limit for the movable wheel, preventing it from falling downwards during rotation and ensuring the stability of the device operation. Disassembling the limiting component facilitates the inspection or cleaning of the movable wheel, mounting groove, and seedling collector body. Simultaneously, the inclined surface of the lower end of the seedling collector body reduces resistance when cutting into the soil during seedling collection, allowing the seedling collector body to more easily insert into the soil around the vegetable seedling roots, reducing soil wear on the seedling collector body, and preventing damage to the vegetable seedling roots due to excessive insertion resistance, thus ensuring the quality of seedling collection with soil attached.

[0014] Furthermore, the outer circumferential surface of the limiting member is connected to the inner circumferential surface of the circular fixing frame, and the top surface of the limiting member covers the mounting groove and fits against the bottom surface of the movable wheel.

[0015] By adopting the above technical solution, after the limiting component is installed, its outer circumferential surface is tightly connected to the inner circumferential surface of the circular fixing frame, forming a stable assembly structure and preventing the limiting component from loosening or shifting during device operation. Simultaneously, the top surface of the limiting component covers the mounting groove, effectively preventing soil debris, weeds, and other impurities generated during seedling collection from entering the mounting groove, thus avoiding impurities affecting the sliding fit between the movable wheel and the inner circumferential surface of the mounting groove and preventing the movable wheel from jamming. Furthermore, the top surface of the limiting component adheres to the bottom surface of the movable wheel, providing bottom support and further limiting the vertical movement of the movable wheel, ensuring the stability of the movable wheel's rotation and guaranteeing stable operation of the seedling collector.

[0016] Furthermore, two fixing plates are fixedly connected to the outer circumference of the circular fixing frame, and telescopic adjustment rods are fixedly installed at the top of the two fixing plates. A support rod is fixedly connected to the top of the telescopic adjustment rod, and two anti-slip grips are provided on the support rod.

[0017] By adopting the above technical solution, the operator holds two anti-slip handles on the support rod with both hands. These handles increase the friction between the hand and the support rod, preventing slippage due to sweaty hands or excessive force, thus ensuring the stability of the device. Simultaneously, the operator can adjust the length of the telescopic adjustment rod according to their height and the height of the seedling picking area: if the operator is tall or the seedling picking position is high, the telescopic adjustment rod can be lengthened; if the operator is short or the seedling picking position is low, the telescopic adjustment rod can be shortened, allowing the operator to operate the device in a comfortable posture and reducing the labor intensity of long-term work. By adjusting the overall position of the device by holding the anti-slip handles, the opening can be accurately aligned with the vegetable seedling to be picked, completing the seedling picking operation.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] (1) This utility model of a seedling picker for transplanting vegetables with soil attached effectively solves the problems of slow power transmission and misalignment of moving parts in traditional equipment through a dual structural design of "gear-external gear ring meshing transmission + annular mounting groove guidance". When the motor drives the gear to rotate, the meshing transmission with the external gear ring of the moving wheel can achieve precise power transmission, ensuring that the rotation speed and angle of the moving wheel are controllable; at the same time, the annular mounting groove provides a closed motion trajectory for the moving wheel, strictly limiting its radial offset, so that the body of the picker always cuts into the soil along the preset path. This structure, combined with the precise positioning of the opening, can avoid seedling compression damage, and the rhythm of the seedling picking action is stable, which can preserve the integrity of the root ball to the greatest extent. Compared with traditional equipment, the seedling picking efficiency is increased by more than 30%, the seedling root integrity rate is increased to more than 95%, and the transplanting mortality rate is significantly reduced.

[0020] (2) The soil-bearing seedling extractor for transplanting vegetables of this utility model features a detachable ring-shaped limiting component that integrates three functions: limiting, protection, and maintenance. Its tight connection with the fixed frame and its support for the bottom of the movable wheels effectively prevent the wheels from shifting or falling off, ensuring stability during high-speed operation. The top surface covering the mounting groove prevents soil debris and weeds from intruding, avoiding jamming of moving parts and reducing equipment failure rate by over 60%. Simultaneously, the detachable nature of the limiting component eliminates the need to disassemble the entire machine for cleaning and maintenance of the movable wheels, mounting groove, and the seedling extractor body, reducing maintenance time to one-third of traditional equipment. Furthermore, the inclined structure at the lower end of the seedling extractor body significantly reduces soil penetration resistance, lowering motor energy consumption and component wear, while also preventing root damage caused by forced soil penetration, further reducing equipment maintenance costs and transplanting losses.

[0026] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0027] To prevent the drawbacks of manual seedling harvesting and the problems of transmission, maintenance, and soil insertion in existing semi-automatic equipment, this utility model improves seedling harvesting efficiency, seedling survival rate, equipment stability and convenience through technological innovation, reduces losses, and enhances the benefits of large-scale vegetable planting and transplanting. Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, an agricultural vegetable transplanting seedling extractor with soil attached includes a circular fixed frame 1, movable wheels 2, and a seedling extractor body 9. The seedling extractor body 9 is fixedly connected to the bottom end of the movable wheels 2. The movable wheels 2 are embedded in the circular fixed frame 1. Both the circular fixed frame 1 and the movable wheels 2 are provided with an opening 3 for agricultural vegetables to pass through. A protective box 4 is fixedly connected to the outer circumference of the circular fixed frame 1. The top of the protective box 4 is provided with a motor 5 that drives the movable wheels 2 to rotate around the axis of the circular fixed frame 1.

[0028] In use, the operator first moves the device to the vegetable planting area where the seedlings are to be harvested, ensuring that the opening 3 on the circular fixed frame 1 and the movable wheel 2 are precisely aligned with the target vegetable seedling, so that the seedling can pass through the opening 3 smoothly without being squeezed or damaged. Then, the motor 5 at the top of the protective box 4 is started. The motor 5 drives the movable wheel 2 to rotate around the axis of the circular fixed frame 1. When the movable wheel 2 rotates, it drives the seedling harvester body 9, which is fixedly connected to the bottom, to move synchronously. The seedling harvester body 9 cuts into the soil at the root of the vegetable seedling as the movable wheel 2 rotates, realizing the operation of harvesting seedlings with soil.

[0029] For example, such as Figure 3 As shown, the present invention also includes a circular fixing frame 1 with an annular mounting groove 6, a movable wheel 2 embedded in the mounting groove 6, and the inner circumferential surface of the movable wheel 2 being slidably connected to the inner circumferential surface of the mounting groove 6.

[0030] In use, when the motor 5 drives the movable wheel 2 to rotate around the axis of the circular fixed frame 1, the movable wheel 2 will slide along the inner circumferential surface of the annular mounting groove 6 on the circular fixed frame 1. The mounting groove 6 provides a stable movement trajectory for the movable wheel 2, effectively limiting the radial offset of the movable wheel 2 during rotation, ensuring that the seedling picker body 9 always moves along the preset path, improving the accuracy of the seedling picking position, and avoiding seedling picking errors or damage to vegetable seedlings due to the offset of the movable wheel.

[0031] For example, such as Figure 3 , Figure 4As shown, the present invention also includes an external gear ring 7 on the movable wheel 2, and a gear 8 that is fixedly mounted inside the protective box 4 on the output shaft of the motor 5. The gear 8 extends into the mounting groove 6 and meshes with the external gear ring 7 of the movable wheel 2.

[0032] When in use, to drive the movable wheel 2 to rotate and activate the seedling extractor body 9, the motor 5 is started. The output shaft of the motor 5 drives the gear 8, which extends into the protective box 4 and is wall-mounted, to rotate. Since the gear 8 extends into the mounting slot 6 and meshes with the external gear ring 7 on the movable wheel 2, the rotation of the gear 8 drives the movable wheel 2 to rotate synchronously through tooth transmission. This gear meshing transmission method can precisely transmit power, ensuring the stability of the rotation speed and angle of the movable wheel 2, thereby making the seedling extraction rhythm of the seedling extractor body 9 controllable, improving seedling extraction efficiency and the integrity of extracting seedlings with soil.

[0033] For example, such as Figure 2 , Figure 3 As shown, the present invention also includes a detachable limiting member 15 at the bottom of the circular fixing frame 1, and the limiting member 15 is annular, and the lower end face of the seedling taker body 9 is provided with an inclined surface 10.

[0034] During use, the annular limiting component 15 at the bottom of the circular fixed frame 1 can be disassembled or installed according to the needs of seedling collection and the maintenance status of the device. Installing the limiting component 15 provides a bottom limit for the movable wheel 2, preventing it from falling downwards during rotation and ensuring the stability of the device's operation. Disassembling the limiting component 15 facilitates the inspection or cleaning of the movable wheel 2, the mounting groove 6, and the seedling collector body 9. Simultaneously, the inclined surface 10 on the lower end of the seedling collector body 9 reduces resistance when cutting into the soil during seedling collection, allowing the seedling collector body 9 to more easily insert into the soil around the vegetable seedling roots, reducing soil wear on the seedling collector body, and preventing damage to the vegetable seedling roots due to excessive insertion resistance, thus ensuring the quality of seedling collection with soil attached.

[0035] For example, such as Figure 2 , Figure 3 As shown, the present invention also includes the following: the outer peripheral surface of the limiting member 15 is connected to the inner peripheral surface of the circular fixing frame 1, and the top surface of the limiting member 15 covers the mounting groove 6 and is attached to the bottom surface of the movable wheel 2.

[0036] During use, after the limiting component 15 is installed, its outer circumferential surface is tightly connected to the inner circumferential surface of the circular fixing frame 1, forming a stable assembly structure to prevent the limiting component 15 from loosening or shifting during device operation. Simultaneously, the top surface of the limiting component 15 covers the mounting groove 6, effectively preventing soil debris, weeds, and other impurities generated during seedling collection from entering the mounting groove 6, thus avoiding impurities affecting the sliding fit between the movable wheel 2 and the inner circumferential surface of the mounting groove 6 and preventing the movable wheel from jamming. Furthermore, the top surface of the limiting component 15 adheres to the bottom surface of the movable wheel 2, providing bottom support for the movable wheel 2, further limiting its vertical movement, ensuring the stability of the movable wheel 2 during rotation, and guaranteeing stable operation of the seedling collector body 9.

[0037] For example, such as Figure 1 As shown, the present invention also includes two fixing plates 11 fixedly connected to the outer circumference of the circular fixing frame 1, and telescopic adjustment rods 12 fixedly installed at the top of the two fixing plates 11. A support rod 13 is fixedly connected to the top of the telescopic adjustment rod 12, and two anti-slip grips 14 are provided on the support rod 13.

[0038] During use, the operator holds the two non-slip handles 14 on the support rod 13 with both hands. The non-slip handles 14 increase the friction between the hand and the support rod 13, preventing the operator from slipping due to sweaty hands or excessive force, thus ensuring the stability of the device. Simultaneously, the operator can adjust the length of the telescopic adjustment rod 12 according to their own height and the height difference of the seedling picking area: if the operator is tall or the seedling picking position is high, the telescopic adjustment rod 12 can be lengthened; if the operator is short or the seedling picking position is low, the telescopic adjustment rod 12 can be shortened, allowing the operator to operate the device in a comfortable posture and reducing the labor intensity of long-term operation. By adjusting the overall position of the device by holding the non-slip handles 14, the opening 3 can be accurately aligned with the vegetable seedling to be picked, completing the seedling picking operation.

[0039] It should be noted that this utility model is a soil-bearing seedling extractor for agricultural vegetable transplanting. The operator holds the two non-slip handles 14 on the support rod 13 with both hands, using the increased friction of the non-slip handles to stabilize the grip on the device. The operator adjusts the length of the telescopic adjustment rod 12 at the top of the fixing plate 11 according to their own height and the height difference of the area to be extracted. When the operator is taller or the seedling extraction position is higher, the adjustment rod is lengthened; when the operator is shorter or the seedling extraction position is lower, the adjustment rod is shortened until the operator can operate the device in a comfortable posture and move it to the vegetable planting area to be extracted. Then, the position of the device is adjusted so that the opening 3 in the circular fixing frame 1 and the movable wheel 2 is precisely aligned with the target vegetable seedling, ensuring that the vegetable seedling can pass through the opening smoothly without being squeezed. To avoid damaging the seedlings during seedling removal, the motor 5 at the top of the protective box 4 is then activated. The motor output shaft drives the gear 8, which is fixed to the wall inside the protective box, to rotate. Because the gear extends into the mounting groove 6 and meshes with the outer gear ring 7 of the movable wheel 2, the rotation of the gear drives the movable wheel 2 to rotate around the axis of the circular fixed frame 1 through tooth transmission. At this time, the movable wheel 2 slides along the inner circumference of the annular mounting groove 6 on the circular fixed frame. The mounting groove provides a stable track for the movable wheel to prevent radial deviation. While the movable wheel rotates, it drives the seedling remover body 9, which is fixedly connected to the bottom, to move synchronously. The seedling remover body reduces the resistance to soil entry by using the inclined surface 10 of the lower end face, and easily cuts into the soil around the roots of the vegetable seedlings to complete the seedling removal operation with soil.

[0040] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
