Abstract
Description
Technical Field
[0001] This utility model mainly relates to the technical field of vegetable seedling cultivation equipment, specifically a vegetable seedling cultivation equipment for vegetable seedling stage cultivation. Background Technology
[0002] In the vegetable planting industry, seedling cultivation is a key link that determines the subsequent growth quality and yield of vegetables. Its core requirement is to provide seedlings with a stable and uniform growth environment, including appropriate water and nutrient supply and good root aeration, while also taking into account space utilization to reduce cultivation costs.
[0003] Currently, traditional vegetable seedling cultivation mostly employs flat seedling trays or fixed seedbeds. These methods have significant limitations: firstly, the flat layout results in low space utilization and a limited number of seedlings per unit area, making it difficult to meet the production capacity demands of large-scale planting; secondly, seedling watering and fertilization rely heavily on manual spraying or drip irrigation systems. Manual spraying easily leads to uneven substrate surface moisture and nutrient loss, while drip irrigation systems require complex piping and are prone to localized blockages, causing some seedlings to suffer from water and nutrient deficiencies, failing to achieve precise and uniform nutrient supply. Furthermore, in traditional seedling devices, if excess substrate water cannot be drained or recovered in time, it not only leads to root rot from water accumulation but also wastes nutrient solution, increasing cultivation costs. Simultaneously, the fixed seedling structure makes it difficult to flexibly adjust the seedling growth environment to adapt to the differentiated light, humidity, and nutrient requirements of different vegetable varieties during the seedling stage, further limiting the improvement of seedling quality and efficiency. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a vegetable seedling raising device for vegetable seedling cultivation, achieved through the following technical solution: A vegetable seedling cultivation device for vegetable seedling cultivation includes a base and support frames fixedly installed on both sides of its top surface. A rolling assembly is provided between the two support frames, and several plant cultivation boxes arranged in a circular array are rotatably installed between the rolling assemblies. The plant cultivation boxes are used to hold seedling substrate and vegetable seedlings. Connecting frames are fixedly installed on both sides of each plant cultivation box, and the connecting frames are rotatably connected to the corresponding rolling assemblies. The top surface of each plant cultivation box is open, and the bottom surface of each plant cultivation box has several evenly distributed permeable holes. A liquid storage tank is provided below the rolling assemblies. The liquid storage tank is connected to the support frame through a lifting assembly. The lifting assembly can drive the liquid storage tank to move up and down along the support frame to adjust the distance between the liquid storage tank and the plant cultivation boxes.
[0005] Furthermore, the scrolling component includes: A rotating shaft is provided between the two support frames. Both ends of the rotating shaft pass through the support frames opposite to it, and the rotating shaft and the support frames are rotatably connected by bearings to ensure stable rotation of the rotating shaft. A geared motor is fixedly installed on the upper part of the outer side of one of the support frames. The output end of the geared motor is fixedly connected to one end of the rotating shaft to provide stable power to the rotating shaft. The rotation speed of the rotating shaft can be controlled by adjusting the speed of the geared motor. The supporting discs are fixedly installed on both sides of the rotating shaft and are coaxially arranged with it. The supporting discs rotate synchronously with the rotating shaft, and the two supporting discs are located between the two supporting frames. The plant cultivation box is rotatably connected to the corresponding supporting discs through the connecting frames set at its two ends.
[0006] Furthermore, the connecting frame includes a mounting base and a support shaft. The mounting base is fixedly installed at both ends of the plant cultivation box. The mounting base is connected to the plant cultivation box by welding or bolting to ensure connection strength. The upper part of the outer side of the mounting base is fixedly installed with the support shaft, and the two support shafts are coaxially arranged. The support shaft passes through the corresponding support disc laterally and is connected to its bearing. The bearing is a deep groove ball bearing to reduce the frictional resistance when the support shaft rotates and ensure that the plant cultivation box rotates smoothly.
[0007] Furthermore, the lifting assembly includes an electric actuator, and a limiting groove is provided on the lower part of the outer side of the support frame. The limiting groove is a rectangular groove structure used to limit the movement direction of the slider. The electric actuator is fixedly installed at the bottom of the limiting groove. The output end of the electric actuator is fixedly installed with a slider. The slider slides with the corresponding limiting groove, and the inner side of the slider is fixedly connected to the side opposite to the liquid storage tank. Furthermore, a drain pipe is integrally fixedly installed at the center of the bottom of the storage tank. The drain pipe is connected to the inside of the storage tank and is used to drain the liquid collected in the storage tank. A manual valve is provided in the middle of the drain pipe.
[0008] Furthermore, it also includes a controller, which is fixedly installed on the outside of another support frame. The controller is a PLC controller, and its surface is equipped with operation buttons and a display screen. It can start and stop the geared motor and electric actuator and adjust the parameters, and can also display the equipment operating status in real time. Furthermore, several evenly distributed counterweights are fixedly installed at the bottom of each plant cultivation box.
[0009] Compared with the prior art, the beneficial effects of this utility model are: 1. This device adopts a three-dimensional structure of "base-support frame-rolling component," assembling multiple plant cultivation boxes in a circular array between two supporting discs. The rolling component drives the cultivation boxes to revolve, breaking the spatial limitations of traditional planar seedling cultivation. Compared to traditional planar seedbeds, it can significantly increase the number of seedlings per unit area, significantly improve space utilization, meet the seedling cultivation capacity requirements of large-scale vegetable planting, and reduce site rental and construction costs.
[0010] 2. The distance between the nutrient solution storage tank and the plant cultivation box can be precisely adjusted via a lifting component. Combined with a rolling component, this allows the plant cultivation box to rotate slowly, ensuring that the bottom of each box is evenly immersed in the nutrient solution. The nutrient solution seeps evenly into the substrate through the drainage holes, avoiding the problems of "localized over-wetting" in traditional spraying or "clogging and nutrient deficiency" in drip irrigation. This ensures consistent nutrient supply to all seedlings, improving the uniformity of seedling growth. Furthermore, after the plant cultivation box is rotated out of the storage tank, excess nutrient solution flows back into the storage tank through the drainage holes, achieving nutrient solution recycling. Compared to traditional one-time supply methods, the nutrient solution loss rate is significantly reduced. Simultaneously, the drain pipe and manual valve at the bottom of the storage tank allow for the periodic discharge of small amounts of waste solution and the replenishment of fresh solution, further reducing resource waste and lowering cultivation costs.

Detailed Implementation
[0013] The present invention will be further described in conjunction with the accompanying drawings and specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the present invention, and these equivalent forms also fall within the scope defined in this application.
[0014] Example: A vegetable seedling raising device for vegetable seedling cultivation like Figure 1 As shown in Figure 6, a vegetable seedling raising device for vegetable seedling cultivation has the following specific structure: The base 10 and support frames 20 fixedly installed on both sides of its top surface are provided. A rolling assembly 30 is provided between the two support frames 20. Several plant cultivation boxes 40 arranged in a circular array are rotatably installed between the rolling assemblies 30. The plant cultivation boxes 40 are used to hold seedling substrate and vegetable seedlings. Connecting frames 50 are fixedly installed on both sides of the plant cultivation box 40. The connecting frames 50 are rotatably connected to the corresponding rolling assemblies 30, allowing the plant cultivation boxes 40 to rotate around the axis of the rolling assembly 30. The top surface of the plant cultivation boxes 40 is open to facilitate sowing and cultivation. The plant cultivation box 40 is used for seedling management and growth. Several evenly distributed permeable holes 401 are provided on the bottom surface of the plant cultivation box 40 to drain excess water from the substrate and prevent water accumulation and rot of the roots. A liquid storage tank 60 is provided below the rolling component 30. The liquid storage tank 60 is used to collect the nutrient liquid drained from the permeable holes 401 of the plant cultivation box 40. The liquid storage tank 60 is connected to the support frame 20 through a lifting component 70. The lifting component 70 can drive the liquid storage tank 60 to move up and down along the support frame 20 to adjust the distance between the liquid storage tank 60 and the plant cultivation box 40.
[0015] The working principle described above is as follows: In use, nutrient solution is injected into the storage tank 60. When it is necessary to replenish the nutrient solution for vegetable seedlings, the storage tank 60 is raised to a preset position via the lifting component 70. The rolling component 30 drives the plant cultivation box 40 to rotate around its axis. At this time, the bottom of the plant cultivation box 40 at the bottom can be immersed in the nutrient solution in the storage tank 60. The nutrient solution then enters the plant cultivation box 40 through the water permeable hole 401, thereby replenishing the nutrient solution in the plant cultivation box 40. When the plant cultivation box 40 at the bottom is removed from the storage tank 60, the excess nutrient solution in the plant cultivation box 40 will be drained through the water permeable hole 401. The nutrient solution is drained and returned to the storage tank 60 to avoid waste and reduce cultivation costs. The circular array of plant cultivation boxes 40 improves space utilization and meets the needs of intensive cultivation of seedling vegetables. After the rolling component 30 rotates once, all the plant cultivation boxes 40 have been replenished with nutrient solution. At this time, the storage tank 60 is moved downward by the lifting component 70 to reset it, thereby ensuring that all the plant cultivation boxes 40 are exposed to the outside, ensuring that the vegetables in the plant cultivation boxes 40 can breathe, ensuring smooth root respiration, reducing the incidence of diseases such as root rot and damping-off in the seedling stage, and improving the survival rate of seedlings. The scrolling component 30 includes: A rotating shaft 301 is provided between the two support frames 20. Both ends of the rotating shaft 301 pass through the support frame 20 opposite to it, and the rotating shaft 301 and the support frame 20 are rotatably connected by bearings to ensure stable rotation of the rotating shaft 301. A geared motor 302 is fixedly installed on the upper part of the outer side of one of the support frames 20. The output end of the geared motor 302 is fixedly connected to a corresponding end of the rotating shaft 301 to provide stable power to the rotating shaft 301. The rotation speed of the rotating shaft 301 can be controlled by adjusting the speed of the geared motor 302. Supporting discs 303 are fixedly installed on both sides of the rotating shaft 301 and are coaxially arranged with it. The supporting discs 303 rotate synchronously with the rotating shaft 301, and the two supporting discs 303 are located between the two supporting frames 20. The plant cultivation box 40 is rotatably connected to the corresponding supporting discs 303 through the connecting frames 50 provided at both ends.
[0016] In use, the device drives the rotating shaft 301 connected to it to rotate synchronously via the geared motor 302. At this time, the support disc 303 rotates synchronously with the rotating shaft 301, ensuring the stability of the revolution trajectory of the plant cultivation box 40 and driving the plant cultivation box 40 to adjust its position. The connecting frame 50 includes a mounting base 501 and a support shaft 502. The mounting base 501 is fixedly installed at both ends of the plant cultivation box 40. The mounting base 501 is connected to the plant cultivation box 40 by welding or bolting to ensure connection strength. The support shaft 502 is fixedly installed on the upper outer side of each mounting base 501, and the two support shafts 502 are coaxially arranged. Each support shaft 502 passes laterally through a corresponding support disc 303 and is connected to its bearing. The bearing is a deep groove ball bearing to reduce frictional resistance during rotation of the support shaft 502 and ensure smooth rotation of the plant cultivation box 40. The support shaft 502 is fixed to the upper outer side of the mounting base 501, allowing the plant cultivation box 40 to rotate around its own support shaft 502 while revolving around the support disc 303, ensuring the plant cultivation box 40 remains vertical, preventing it from tipping over, and improving the reliability of the device.
[0017] The lifting assembly 70 includes an electric actuator 701. Limiting grooves 201 are formed on the lower outer side of the support frame 20. The limiting grooves 201 are rectangular and used to limit the movement direction of the sliders 702. The electric actuator 701 is fixedly installed at the bottom of each limiting groove 201. A slider 702 is fixedly installed at the output end of each electric actuator 701. Each slider 702 slides in cooperation with its corresponding limiting groove 201, and the inner side of each slider 702 is fixedly connected to the opposite side of the liquid storage tank 60. The electric actuator 701 extends and retracts, driving the slider 702 to slide along the limiting groove 201, thereby raising and lowering the liquid storage tank 60. The rectangular limiting grooves 201 and the sliders 702 cooperate to strictly limit the lifting trajectory of the liquid storage tank 60, preventing lateral deviation and preventing tilting and leakage of the liquid storage tank 60. A drain pipe 601 is integrally fixedly installed at the center of the bottom of the liquid storage tank 60. The drain pipe 601 communicates with the inside of the liquid storage tank 60 and is used to drain the liquid collected in the liquid storage tank 60. A manual valve 602 is provided in the middle of the drain pipe 601. The manual valve 602 adopts a ball valve structure, which makes it easy for the operator to control the opening and closing of the drain pipe 601, and can periodically drain waste liquid or clean the liquid storage tank 60. It also includes a controller 80, which is fixedly installed on the outside of another support frame 20. The controller 80 is a PLC controller with operation buttons and a display screen on its surface. It can start and stop the geared motor 302 and the electric actuator 701 and adjust their parameters. It can also display the equipment operating status in real time. During use, the controller 80 sends the same control signal to the two electric actuators 701 to ensure that the extension speed and extension amount of the electric actuators 701 are consistent, preventing the liquid storage tank 60 from tilting due to asynchronous lifting at both ends, and ensuring the stability of the equipment operation. Several evenly distributed counterweights 90 are fixedly installed at the bottom of each plant cultivation box 40. The counterweights 90 enhance the "self-standing" effect of the plant cultivation box 40 through gravity compensation, preventing tilting and substrate spillage caused by uneven weight of substrate or seedlings inside the cultivation box, and further improving the reliability of the device.
