Description

Technical Field

[0001] This utility model relates to the field of seedling technology, and in particular to a seedling device. Background Technology

[0002] In agronomy, seedling raising refers to the process of cultivating seedlings in a specific environment (such as a nursery, hotbed, or greenhouse) in preparation for future transplanting to the field. This process not only helps improve crop survival rates and growth quality but also effectively extends the growing season, allowing plants to be sown earlier in unsuitable seasons, thus achieving more efficient agricultural production. In practice, seedling raising often utilizes facilities such as seedling trays, greenhouses, or hotbeds to ensure that seedlings grow under suitable temperature, humidity, and light conditions.

[0003] In existing technologies, multiple seedling trays require manual handling for positioning and watering, which is inefficient and prone to uneven watering due to differences in operation. While existing W-type vertical circulating seedling beds can circulate and move seedlings or seeds, the external watering system can easily spray water onto the ground during watering or fertilization, resulting in waste. Therefore, we propose a seedling device to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a seedling raising device.

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

[0006] A seedling raising device includes a top frame, a water supply frame and an L-shaped frame fixedly connected to the bottom of the top frame, four sprockets rotatably connected inside the top frame, three of which are fixedly connected to the top of a T-shaped shaft, a reduction motor fixedly connected to the top of the top frame, one end of the output shaft of the reduction motor passing through the top of the top frame and fixedly connected to the top of another sprocket, the outer walls of the four sprockets being meshed with the same chain, the bottom of the chain being fixedly connected to multiple hooks, the outer wall of the chain being provided with a suspension assembly, the outer wall of the water supply frame being fixedly embedded with a water outlet pipe, and the outer wall of the water outlet pipe being fixedly interconnected with multiple atomizing nozzles.

[0007] Preferably, the suspension assembly includes multiple hanging rings, which are respectively fitted onto the outer walls of multiple hooks. A vertical pole is fixedly connected to the bottom of each hanging ring. Multiple seedling trays are uniformly fitted onto the outer wall of the vertical pole. A ring-shaped baffle is fixedly connected to the top of each seedling tray. A circular base is fixedly connected to the bottom of the vertical pole. The vertical pole and the multiple seedling trays are supported by the suspension assembly.

[0008] Preferably, the top frame has three circular holes at its top, and the inner walls of the three circular holes are rotatably connected to the outer walls of three T-shaped shafts, which are rotated by setting auxiliary sprockets on the T-shaped shafts.

[0009] Preferably, a door curtain panel is fixedly connected inside the water replenishment frame, and multiple soft door curtains are evenly fixedly connected to the bottom of the door curtain panel to reduce water mist dissipation.

[0010] Preferably, a filter screen is fixedly connected inside the water replenishment frame to prevent external impurities from entering the collection pipe.

[0011] Preferably, a collection pipe is fixedly connected to the outer wall of the water replenishment frame, and a pump body is fixedly connected to one end of the water outlet pipe.

[0012] Compared with the prior art, the advantages of this utility model are:

[0013] This solution utilizes a circulating structure consisting of a geared motor, sprockets, and chains to achieve mobile watering of multiple seedling trays, eliminating the need for manual handling and alignment, significantly improving operational efficiency, and avoiding uneven watering caused by differences in manual operation, ensuring uniform soil moisture in each seedling tray. Simultaneous watering and fertilization are achieved through atomizing nozzles, saving labor costs associated with separate fertilization and ensuring even fertilizer distribution, reducing the risk of seedling burn or nutrient deficiency. The watering frame and soft curtain effectively reduce water mist overflow, while water is collected and recycled through a collection pipe to prevent waste and slippery surfaces.

[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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0021] Depend on Figures 1-4 As shown, a seedling raising device is disclosed, including a top frame 1. A water supply frame 2 and an L-shaped frame 3 are fixedly connected to the bottom of the top frame 1. Four sprockets 4 are rotatably connected inside the top frame 1. T-shaped shafts 5 are fixedly connected to the top of three of the sprockets 4. Three round holes are opened on the top of the top frame 1. The inner walls of the three round holes are rotatably connected to the outer walls of the three T-shaped shafts 5 respectively. The T-shaped structure of the T-shaped shafts 5 not only restricts the axial displacement of the sprockets 4, but also reduces the frictional resistance when the sprockets 4 rotate through the rotatable connection with the top frame 1.

[0022] A geared motor 6 is fixedly connected to the top of the top frame 1. One end of the output shaft of the geared motor 6 passes through the top of the top frame 1 and is fixedly connected to the top of another sprocket 4. The outer walls of the four sprockets 4 are meshed with the same chain 7. The closed-loop design of the chain 7 enables the cyclical movement of the seedling trays 11, ensuring that all seedling trays 11 can periodically enter the water replenishment frame 2 for water replenishment. The chain 7 is made of high-strength and wear-resistant material. The closed-loop design ensures that the tension is evenly distributed during transmission. An existing tensioning wheel is added to tension it. The tensioning wheel is located on the side of the chain 7 and does not affect the movement of the hook 8.

[0023] Multiple hooks 8 are fixedly connected to the bottom of the chain 7. A water outlet pipe 16 is fixedly embedded in the outer wall of the water supply frame 2. A collection pipe is fixedly connected to the outer wall of the water supply frame 2. A pump body is fixedly connected to one end of the water outlet pipe 16.

[0024] Multiple atomizing nozzles 17 are fixedly connected to the outer wall of the water outlet pipe 16. The atomizing nozzles 17 spray water or liquid fertilizer evenly onto the soil surface of the seedling tray 11, avoiding the problem of local water accumulation eroding seeds or soil compaction caused by traditional direct spray nozzles.

[0025] A filter screen 18 is fixedly connected inside the water supply frame 2, and a curtain panel 14 is fixedly connected inside the water supply frame 2. Multiple soft curtains 15 are evenly fixedly connected to the bottom of the curtain panel 14. The soft curtains 15 are soft and elastic, and can be easily pushed open when the seedling tray 11 enters or leaves the water supply frame 2, and then automatically close. This can prevent water mist from overflowing from the water supply frame 2, reduce water and fertilizer loss, and does not affect the circulation and movement of the seedling tray 11, thus balancing sealing and passage.

[0026] The outer wall of the chain 7 is provided with a suspension assembly, which includes multiple hanging rings 9. The multiple hanging rings 9 are respectively fitted onto the outer wall of multiple hooks 8. The bottom of the hanging ring 9 is fixedly connected to a vertical rod 10. Multiple seedling trays 11 are evenly fixedly fitted onto the outer wall of the vertical rod 10. The hooks 8 and the hanging rings 9 cooperate to connect the suspension assembly with the chain 7. Its hook structure design makes the hanging rings 9 easy to install and remove, which can not only ensure the connection is firm when suspended and prevent the seedling trays 11 from falling, but also make it easy to adjust the number of suspension assemblies according to the number of seedlings, thus improving the flexibility of the device.

[0027] The top of each of the multiple seedling trays 11 is fixedly connected with an annular baffle 12. The annular baffle 12 can prevent the soil in the tray from overflowing due to the movement of the seedling tray 11 or the shaking when watering, and at the same time prevent the water mist sprayed from the atomizing nozzle 17 from splashing outside the tray. The bottom of the upright 10 is fixedly connected with a circular base 13.

[0028] Working principle: During use, the soil for seedling cultivation is placed in the seedling tray 11, and the seeds are located in the soil. Multiple seedling trays 11 are supported by a circular base 13 and a vertical pole 10. The hanging rings 9 are suspended from the hooks 8. As the reduction motor 6 operates, it drives the sprocket 4 connected to it to rotate. The rotation of the sprocket 4 drives the meshing chain 7 to rotate. The rotation of the chain 7 drives the other three sprockets 4 to rotate, which can drive multiple hooks 8 and multiple hanging rings 9 to move in a circular motion. When the hanging rings 9 drive the vertical pole 10 to move into the water replenishment frame 2, the operation of the pump body draws external water (water tank) to the water outlet pipe 16. As multiple atomizing nozzles 17 spray out, the soil in the multiple seedling trays 11 is moistened. An appropriate amount of liquid fertilizer can be added to the external water source (water tank) to achieve the effect of fertilization. The sprayed water mist is blocked by the soft curtain 15 to reduce the dispersion, and the water mist falling downwards is collected by the collection pipe and existing collection equipment to reduce waste.

[0029] It should be noted that when actually put into use, an existing PLC controller can be added. The PLC controller is electrically connected to the geared motor 6 and the pump body to facilitate the control of the overall operation.
