A type of lifting seedbed

Abstract

This utility model relates to the field of agricultural planting technology, specifically a lifting seedbed, comprising multiple sets of seedbed bodies, with two seedbed bodies in each set. Each seedbed body has a lifting assembly at its bottom, including a fixed cylinder with a longitudinally sliding support column inside. Between each set of fixed cylinders is a first adjustment assembly for controlling the opposing sliding of each support column and providing self-locking. At the top of each support column is a second adjustment assembly for controlling the rotation of the seedbed body and providing self-locking. By setting the first and second adjustment assemblies, adjacent seedbeds can be controlled to move in opposite directions with one rising and one falling motion, as well as rotate independently. This allows seedlings to receive uniform sunlight, improving survival rates while avoiding repetitive lifting and lowering operations, significantly improving adjustment efficiency. Furthermore, both the lifting and rotation adjustments have a self-locking effect, thus locking the height and rotation angle of the seedbed body.

Description

Technical Field

[0001] This utility model relates to the field of agricultural planting technology, and in particular to a lifting seedbed. Background Technology

[0002] Seedbeds are the core facilities for seedling cultivation and planting in modern agriculture. They are widely used in greenhouses, flower cultivation, vegetable seedling cultivation, rice breeding, and traditional Chinese medicine cultivation. By optimizing environmental control, improving space utilization and ease of operation, they enable efficient and intensive production.

[0003] Traditional horizontal seedbeds cannot adjust the angle, and seedlings that receive light from a fixed direction for a long time (such as single-sided lighting in a greenhouse) will have their stems tilted and become weak due to phototropism. Therefore, it is necessary to manually turn the seedlings over periodically. During the manual turning process, the seedling roots are easily damaged by collisions and compression, which not only affects the survival rate but also wastes labor. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the prior art, solve the problems mentioned in the background art, and provide a lifting seedbed.

[0005] The objective of this utility model is achieved through the following technical solution: a lifting seedbed, comprising multiple sets of seedbed bodies, each set containing two seedbed bodies, each seedbed body having a lifting assembly at its bottom, the lifting assembly including a fixed cylinder, the interior of which a support column is longitudinally slidably mounted; between each set of fixed cylinders, a first adjusting assembly for controlling the opposing sliding of each set of support columns and self-locking is provided, the top of each support column having a second adjusting assembly for controlling the rotation of the seedbed body and self-locking is provided, the first adjusting assembly having a first driving assembly for controlling its operation, multiple first adjusting assemblies being connected in series through a first driving assembly, and the second adjusting assembly having a second driving assembly for controlling its operation.

[0006] Preferably, the first adjusting component includes a fixed plate fixedly disposed between a set of fixed cylinders. A first splined shaft is rotatably disposed on the fixed plate. A gear is splinedly connected to one end of the first splined shaft. Two racks are symmetrically meshed on the outer surface of the gear. The two racks are respectively connected to the two support columns through two fixed rods. A first worm gear is splinedly connected to the end of the first splined shaft away from the gear. A first worm is meshed on the outer surface of the first worm gear. A sliding groove is provided on the fixed cylinder corresponding to the position of the fixed rod.

[0007] Preferably, the first worm gear has a insertion hole at its center, and the first drive assembly includes a insertion rod that is inserted into the insertion hole, and one end of the insertion rod is fixedly provided with a first hand crank for controlling its rotation.

[0008] Preferably, the second adjustment component includes a second splined shaft rotatably disposed at the top of the support column, a second worm gear splinedly connected to the outer surface of the second splined shaft, a second worm meshing with the outer surface of the second worm gear, and the top end of the second splined shaft fixedly installed at the center of the bottom of the seedbed body.

[0009] Preferably, the second drive assembly includes an extension rod fixedly mounted on one end of the second worm gear, and a second hand crank is fixedly provided on the end of the extension rod away from the second worm gear.

[0010] Preferably, each of the fixed cylinders is fixedly installed with a first support member at the position corresponding to the first worm gear, and the first worm gear is rotatably connected to the first support member.

[0011] Preferably, the support column is fixedly installed with a second support member at both ends corresponding to the second worm, and the second worm is rotatably connected to the second support member.

[0012] The beneficial effects of this lifting seedbed are as follows: By setting up the first and second adjustment components, it is possible to control the adjacent seedbeds to move in opposite directions with one rising and the other falling, as well as to adjust them independently. This allows the seedlings to receive sunlight evenly, preventing local seedlings from tilting or becoming lopsided due to prolonged exposure to light from one side. This reduces the need for manual seedling repositioning and significantly improves adjustment efficiency. At the same time, both the lifting and rotation adjustments have a self-locking effect, which can lock the height and rotation angle of the seedbed body, preventing the seedbed body from settling or shaking due to accidental contact or mechanical failure, avoiding seedling tilting and substrate spillage, and ensuring the safety of the equipment and operators.

[0026] Additional aspects and advantages of this invention will be further set forth in the description which follows in conjunction with the accompanying drawings, and in part will be obvious from the description or may be learned by practice of the invention.

[0027] like Figures 1 to 10As shown, a lifting seedbed includes multiple seedbed bodies 1, with two seedbed bodies 1 in each group. Each seedbed body 1 has a lifting assembly 2 at its bottom. The lifting assembly 2 includes a fixed cylinder 201, with a support column 202 slidably mounted longitudinally inside the fixed cylinder 201. A first adjustment assembly 3 is provided between each group of fixed cylinders 201 to control the opposing sliding of each group of support columns 202 and to self-lock. A second adjustment assembly 4 is provided at the top of the support column 202 to control the rotation of the seedbed body 1 and to self-lock. A first drive assembly 5 is provided on the first adjustment assembly 3 to control its operation. Multiple first adjustment assemblies 3 are connected in series through a first drive assembly 5. A second drive assembly 6 is provided on the second adjustment assembly 4 to control its operation.

[0028] The first adjusting assembly 3 includes a fixed plate 301 fixedly disposed between a set of fixed cylinders 201. A first splined shaft 302 is rotatably mounted on the fixed plate 301. A gear 303 is splinedly connected to one end of the first splined shaft 302. Two racks 304 are symmetrically meshed on the outer surface of the gear 303. The two racks 304 are respectively connected to two support columns 202 through two fixed rods 305. A first worm gear 306 is splinedly connected to the end of the first splined shaft 302 away from the gear 303. A first worm is meshed on the outer surface of the first worm gear 306. 307. Each set of fixed cylinders 201 is fixedly installed with a first support member 7 at the position corresponding to the first worm 307. The first worm 307 is rotatably connected to the first support member 7. The first support member 7 is provided with a rotation hole at the position corresponding to the first worm 307. The first worm 307 is connected to its corresponding rotation hole through a bearing. By using the bearing, the friction force when the first worm 307 rotates can be reduced, and the stability when the first worm 307 rotates can be improved. The fixed cylinder 201 is provided with a sliding groove 2011 at the position corresponding to the fixed rod 305.

[0029] A insertion hole 3071 is provided at the center of the first worm gear 307. The first drive assembly 5 includes an insertion rod 501 that is inserted into the insertion hole 3071. The insertion hole 3071 is a regular hexagonal hole, and the cross-sectional shape of the insertion rod 501 is also a regular hexagon. By utilizing the cooperation between the insertion rod 501 and multiple insertion holes 3071, multiple first worm gears 307 can be controlled to rotate synchronously. One end of the insertion rod 501 is fixedly provided with a first hand crank 502 for controlling its rotation. The first hand crank 502 extends to the outside of the seedbed body 1, allowing the user to directly contact the first hand crank 502 and control the rotation of the first worm gear 307.

[0030] The second adjustment component 4 includes a second splined shaft 401 rotatably mounted on the top of the support column 202. A second worm gear 402 is splinedly connected to the outer surface of the second splined shaft 401. A second worm 403 is meshed on the outer surface of the second worm gear 402. Second support members 8 are fixedly installed on both ends of the support column 202 corresponding to the two ends of the second worm 403. The second worm 403 is rotatably connected to the second support member 8. The second support member 8 has a rotation hole at the position corresponding to the second worm 403. The second worm 403 is connected to its corresponding rotation hole through a bearing. By using the bearing, the friction force of the second worm 403 during rotation can be reduced, and the stability of the second worm 403 during rotation can be improved. The top end of the second splined shaft 401 is fixedly installed at the center of the bottom of the seedbed body 1.

[0031] The second drive assembly 6 includes an extension rod 601 fixedly installed at one end of the second worm gear 403. A second hand crank 602 is fixedly provided at the end of the extension rod 601 away from the second worm gear 403. The second hand crank 602 extends to the outside of the seedbed body 1, so that the user can directly contact the second hand crank 602 and control the second worm gear 403 to rotate.

[0032] The work process is as follows:

[0033] S1. When it is necessary to rotate the seedbed body 1, firstly, the first hand crank 502 controls the rotation of the plug rod 501. Then, by utilizing the cooperation between the plug rod 501 and multiple plug holes 3071, multiple first worm gears 307 rotate synchronously. Then, by utilizing the meshing between the first worm gear 307 and the first worm wheel 306, and the spline connection between the gear 303 and the first worm wheel 306 and the first spline shaft 302, the first worm wheel 306 can drive the first spline shaft 302 to rotate. At the same time, the first spline shaft 302 drives the gear 303 to rotate. When the gear 303 rotates, by utilizing the two racks 304 symmetrically arranged on both sides of the gear 303 and meshing with the gear 303, the two racks 304 can control the two support columns 202 to slide in opposite directions (one slides upward and the other slides downward) through the two fixed rods 305, thereby indirectly controlling the staggered lifting and lowering of each group of seedbed bodies 1 (for example, odd-numbered seedbed bodies 1 rise, and even-numbered seedbed bodies 1 fall).

[0034] S2. After the seedbed body 1 is adjusted in height, the extension rod 601 and the second worm gear 403 are rotated by the second hand crank 602. Then, by using the meshing between the second worm gear 403 and the second worm wheel 402 and the spline connection between the second worm wheel 402 and the second spline shaft 401, the second spline shaft 401 can drive the seedbed body 1 to rotate.

[0035] S3. The adjacent seedbed bodies 1 move in opposite directions with one rising and one falling. Compared with the independent lifting and lowering of a single seedbed body 1, it can achieve double the relative displacement in the same vertical space. There is no need to lift a single seedbed body 1 to an excessively high position, reducing the dependence on the top space of the greenhouse. It is especially suitable for old greenhouses with limited floor height or vertical cultivation scenarios.

[0036] S4. Staff can raise and lower the seedbed body 1 by using the first hand crank 502 on one side, and then rotate it by using the second hand crank 602 on the other side of the seedbed body 1. This eliminates the need to walk around to the opposite side of the seedbed body 1, reducing the walking path and improving operational efficiency.

[0037] S5. By utilizing the first worm gear 306, the first worm 307, the second worm gear 402, and the second worm 403, a self-locking effect can be achieved after adjustment, thereby locking the height and rotation angle of the seedbed body 1, preventing the seedbed body 1 from settling or shaking due to accidental contact or mechanical failure, and avoiding seedlings tipping over and substrate spillage; at the same time, the synchronicity of the opposing movement can reduce the risk of collision between the seedbed bodies 1, ensuring the safety of the equipment and operators.

[0038] 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 claimed utility model.
