Description

Technical Field

[0001] This utility model relates to the field of vegetable transplanting technology, and in particular to a vegetable transplanting positioning clamp. Background Technology

[0002] Vegetable transplanting is a technical process of transferring pre-cultivated vegetable seedlings from the nursery bed to the field for planting. The core purpose is to optimize the growth space and environment through artificial intervention, shorten the growth cycle of crops in the field, and increase yield.

[0003] For example, patent number CN219981520U discloses a tool for transplanting leafy vegetables, including an inner sleeve. An actuator is slidably connected to the outer wall of the inner sleeve. A positioning plate is installed on the top of the actuator, and a ground-inserting device is installed at the bottom of the actuator. The inner wall of the ground-inserting device is slidably connected to the inner sleeve. The ground-inserting device consists of four identical arc-shaped ground tubes, the inner walls of which are slidably connected to the inner sleeve. Through this ground tube structure, combined with a telescopic rod, the ground tubes are quickly driven into the ground. Then, the bottom plate is controlled to cut off the rootstock at the bottom of the ground tube, thereby achieving the overall transplanting of leafy vegetables and improving the survival rate. The positioning plate and positioning rod allow for the transplanting of leafy vegetable roots of different diameters, improving transplanting efficiency and expanding the device's application range. The sliding structure also facilitates manual operation.

[0004] However, the size of the auxiliary tools used for transplanting existing vegetable seedlings is relatively fixed. When transplanting crops with large leaves, the required tool size is also large, resulting in low versatility and easy damage to the spread leaves. In addition, inserting and pulling the tools into the soil is difficult, making the operation inconvenient and affecting the efficiency and effectiveness of transplanting. Utility Model Content

[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0025] Vegetable transplanting is the technical process of transferring pre-cultivated vegetable seedlings from a nursery bed (or container) to the field for planting. The core purpose is to optimize the growth space and environment through artificial intervention, shorten the crop's growth cycle in the field, and increase yield. Specific points include: seedling standards (selecting robust seedlings with 3-5 true leaves, with priority given to seedlings with female flowers for cucurbits), timing (choosing sunny afternoons in spring and cloudy days / evenings in summer and autumn, with a stable soil temperature ≥15℃), root protection (transplanting with an intact soil ball; bare-root seedlings need to be dipped in rooting hormone to prevent root damage), planting operation (keeping a 2cm original soil mark during planting; tomatoes should be planted at a 45° angle to promote adventitious root development), water and fertilizer management (thoroughly watering after planting to help the roots establish, and supplementing with water 3 days later, supplemented with 0.2% borax to promote root development), and post-planting care (shading and sun protection for 3-5 days, controlling watering to encourage root growth). It is necessary to strictly avoid problems such as low temperature freezing of seedlings, root rot due to rain, and aging of large seedlings, so as to ultimately achieve the goal of zero root damage, seedling recovery period of ≤3 days, and survival rate of >95%.

[0026] The core advantages of vegetable transplanting lie in saving 30-50% on seed costs, extending the effective growing period by 15-20 days, and improving land utilization (crop succession efficiency increases by over 35%). Centralized seedling raising avoids early frost damage / pests and diseases and allows for the selection of robust seedlings (survival rate >90%). Furthermore, precise and controllable planting density increases solanaceous crop yields by 20%-30%. However, the main drawbacks of vegetable transplanting include high labor costs (5-8 man-hours per acre), the risk of root damage (bare-root seedlings experience a 20%-40% decrease in water absorption), and strict technical requirements: mechanization rates in hilly areas are <30%, improper operation can easily lead to stem rot / stunted seedlings, and shading / temperature control facilities (such as mulch film to increase temperature by 3-5℃) are required. Special crops face significant limitations; for example, transplanting spinach may cause taproot damage and yield reduction, while direct seeding of beans / cucumbers may extend the harvest period.

[0027] To improve the efficiency of large-scale vegetable cultivation, the standardized operation mode of "centralized seedling raising + facility transplanting" is now widely adopted in agricultural production. This technology system first involves high-density sowing (such as 128-cell tray seedling raising) in modern seedling bases, cultivating robust seedlings through precise control of temperature and humidity (25-28℃ during the day / 15-18℃ at night) and light intensity (8000-12000 lux). When leafy vegetables (such as spinach and rapeseed) grow to the 4-6 true leaf stage (approximately 20-25 days), their root systems have formed dense root balls (3-5cm in diameter). At this time, the clamping planting device of a fully automatic transplanter can completely extract the root ball, ensuring a root integrity of over 95%. The transplanting process requires the use of a laser leveler to prepare the land (ridge flatness error ≤2cm) and pre-laying drip irrigation tape. Within 48 hours of transplanting, continuous watering is provided via pressure-compensated drippers (flow rate 1.2L / h) to shorten the seedling establishment period to 3-5 days. For special varieties such as head lettuce, a soil-bearing transplanting technique (root ball diameter 8-10cm) is also necessary to protect the taproot, combined with gibberellin (10mg / L) root irrigation to promote new root growth. This method can increase land turnover by 40% compared to traditional direct seeding, and stably control the harvest cycle of leafy vegetables to 35-45 days.

[0028] Existing vegetable transplanting techniques mainly include two types: traditional seedbed transplanting and modern facility transplanting. Traditional methods involve cultivating robust seedlings (3-5 true leaves stage) in open-field seedbeds, protecting the root system by lifting the seedlings with a soil ball, and prioritizing transplanting on cloudy days or in the evening to reduce transpiration damage. Thorough watering is done at planting, maintaining the original planting depth. For solanaceous vegetables, a 45° angled planting is recommended to promote adventitious root development. Modern facility transplanting relies on tray seedling cultivation technology, using standardized 128-cell or 72-cell trays to cultivate standardized seedlings. This is combined with fully automated transplanting machines for precise planting, controlling plant spacing error within ±5%, saving up to 60% of labor costs per acre. Specialized techniques include differentiated solutions such as shallow planting of peppers to prevent stem rot, moderately deep planting of eggplants to prevent lodging, and high-ridge planting of cucurbits to prevent waterlogging, as well as supporting measures such as mulching to increase soil temperature (raising soil temperature by 3-5℃ in early spring), shade netting to lower temperature (40% shading rate in summer), and precise drip irrigation. After transplanting, by providing shade for 3-5 days to help the seedlings recover, controlling watering to encourage root growth, and other management methods, the survival rate can reach over 90%, saving 30-50% of seeds compared to direct seeding.

[0029] Existing vegetable transplanting positioning technologies primarily rely on the collaboration of mechanical structures and intelligent systems to achieve precise planting. Traditional manual transplanting uses a rope marking method, marking lines according to preset plant and row spacing (e.g., 40×60cm for tomatoes). Semi-automatic transplanters achieve a longitudinal positioning accuracy of ±2cm through a chain-type seedling delivery mechanism combined with a furrow opener. Modern fully automatic transplanters integrate machine vision and GPS navigation, using a CCD camera to identify the seedling tray hole positions, combined with a servo motor to control the planting arm, achieving a horizontal positioning error of ≤5mm. Special planting requirements, such as slanted planting (45°) of solanaceous vegetables, can be achieved by adjusting the tilt angle of the planter using an angle sensor. Ridge-grown vegetables (e.g., cucumbers) use a laser level to assist in ridging, ensuring a standardized ridge height of 25cm±1cm. Intelligent systems can also dynamically adjust plant spacing based on soil moisture conditions, such as automatically reducing the spacing by 10% in arid areas to optimize water use.

[0030] Please see Figures 1-5This utility model provides an embodiment of a vegetable transplanting positioning clamp, including a transmission housing 1, a bevel gear 2 disposed on the inner side of the transmission housing 1, a drive motor 3 disposed at the upper end of the transmission housing 1 for driving the bevel gear 2 to rotate, a bevel gear 4 disposed on the side of the bevel gear 2, a frame 5 fixedly mounted on the outer side of the transmission housing 1, a limit groove 6 formed on the surface of the frame 5, a drive screw 7 disposed on the inner side of the limit groove 6, a movable frame 8 disposed below the frame 5, and a gathering plate 9 fixedly mounted at the lower end of the movable frame 8. A support frame 10 is provided on the outer side of the gathering plate 9, and a transplanting shovel 11 is provided below the support frame 10. A drive component 12 for driving the transplanting shovel 11 to move is provided at the upper end of the support frame 10. Multiple gathering plates 9 are controlled to move closer to each other by the drive motor 3 to achieve the gathering and limiting of vegetable leaves. The drive component 12 drives the transplanting shovel 11 to insert into the soil to clamp the vegetable roots and soil, making it easier to move the vegetables into the planting trough. Then, the transplanting shovel 11 is controlled to rise to release the clamping of the vegetable roots, so that the vegetables are transplanted into the planting trough.

[0031] Please see Figures 1-4 In this embodiment, the drive motor 3 is fixedly connected to the upper end of the transmission housing 1, the output end of the drive motor 3 extends to the inner side of the transmission housing 1 and is fixedly connected to the first bevel gear 2, the second bevel gear 4 is arranged in a ring array, the second bevel gear 4 and the first bevel gear 2 mesh with each other, the limiting groove 6 and the drive screw 7 are both arranged in a ring array, the two ends of the drive screw 7 are rotatably connected to the frame 5, one end of the drive screw 7 extends to the inner side of the transmission housing 1 through a rotating shaft and is fixedly connected to the second bevel gear 4, the moving frame 8 is arranged in a ring array, the upper end of the moving frame 8 is slidably connected to the inner side of the limiting groove 6, and the drive screw 7 and the moving frame 8 are threadedly connected.

[0032] When the drive motor 3 drives the bevel gear 2 to rotate, the bevel gear 2 drives the bevel gear 4 to rotate, the bevel gear 4 drives the drive screw 7 to rotate, and the drive screw 7 drives the moving frame 8 to slide along the inner side of the limiting groove 6. The gathering plates 9 are arranged in a ring array and have an arc-shaped structure design. The sides of adjacent gathering plates 9 are adapted to each other, and multiple gathering plates 9 are fitted on the outside of the vegetables. By controlling the rotation of the bevel gear 2 through the drive motor 3, the multiple bevel gears 4 drive the drive screw 7 to rotate, and control the moving frame 8 to slide along the limiting groove 6, so that the multiple gathering plates 9 are close to each other, thereby realizing the gathering and limiting of the vegetable leaves and avoiding damage during transplanting.

[0033] Please see Figures 2-5In this embodiment, the support frame 10 and the outer side of the gathering plate 9 are fixedly connected, and the drive component 12 is fixedly connected to the support frame 10. The drive component 12 is an electric telescopic rod. The output end of the electric telescopic rod is fixedly connected to the upper end of the transplanting shovel 11. The transplanting shovel 11 is arranged in a ring array and has a triangular structure design. The sides of adjacent transplanting shovels 11 are adapted to each other. After the gathering plate 9 is pressed tightly against the surface of the planting soil, the transplanting shovel 11 is driven to move down by multiple drive components 12, so that the transplanting shovel 11 is inserted into the soil. Multiple transplanting shovels 11 approach each other and clamp the vegetable roots and the soil. At this time, the clamp is lifted as a whole and moved to the planting location, so that the lower end of the transplanting shovel 11 is inserted into the pre-dug planting trough. Then, the drive component 12 drives the transplanting shovel 11 to rise, releasing the clamp on the vegetable roots. Then, the drive motor 3 controls the multiple gathering plates 9 to move away from each other, so that the clamp is lifted away from the vegetables, and the vegetables are transplanted into the planting trough.

[0034] During operation, multiple gathering plates 9 are fitted onto the outside of the vegetables. The drive motor 3 controls the rotation of the first bevel gear 2, which in turn drives the drive screw 7 to rotate. This controls the moving frame 8 to slide along the limiting groove 6, bringing the multiple gathering plates 9 closer together to achieve the gathering and limiting of the vegetable leaves. Multiple drive components 12 drive the transplanting shovel 11 to move downwards, inserting it into the soil to clamp the vegetable roots and the soil. At this point, the clamp is lifted as a whole and moved to the planting location, so that the lower end of the transplanting shovel 11 is inserted into the pre-dug planting trough. Then, the drive component 12 drives the transplanting shovel 11 to rise, releasing the clamp on the vegetable roots. Finally, the drive motor 3 controls the multiple gathering plates 9 to move away from each other, lifting the clamp away from the vegetables and transplanting them into the planting trough.

[0035] Through the above steps, the drive motor 3 controls multiple gathering plates 9 to move closer to each other, thereby closing and limiting the vegetable leaves. The drive component 12 drives the transplanting shovel 11 to be inserted into the soil, clamping the vegetable roots and soil, making it easier to move the vegetables into the planting trough. This solves the problems of low versatility of auxiliary tools when transplanting vegetable seedlings, which can easily damage the unfolded leaves of the crops, and the difficulty in inserting and pulling out the soil.
