Description

Technical Field

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

[0002] In the process of modern agricultural development, seedling raising, as a key starting point for crop planting, has a profound impact on the subsequent growth, yield, and quality of crops. High-quality seedlings are the foundation for efficient and stable crop production, directly impacting the economic and social benefits of agricultural production. A search revealed a Chinese patent with authorization number CN222235865U, which discloses a smart agricultural seedling raising device. This device includes a frame and a supplementary lighting mechanism. The front surface of the frame has positioning holes, and a sliding sleeve is fitted onto the outer side of the frame. A positioning rod passes through the front of the sliding sleeve. This smart agricultural seedling raising device, through the coordinated use of the positioning holes, sliding sleeve, and positioning rod, allows for adjustment of the spacing between the trays on one side of the sliding sleeve based on the height of the seedlings being cultivated. When the seedlings are relatively short, the spacing between the trays can be appropriately reduced, increasing the number of trays to cultivate more seedlings. Conversely, when the seedlings are taller, the spacing between the trays can be appropriately increased, allowing the device to be adjusted according to the seedling growth.

[0003] The smart agricultural seedling raising device in the aforementioned patent has the following shortcomings: when adjusting the height of the tray, the device requires manually rotating the positioning rod. After adjusting to the appropriate position, the positioning rod is rotated again and locked into the positioning hole. This makes the adjustment of the tray inconvenient and reduces the efficiency of use. Therefore, an agricultural technology seedling raising device was designed. Utility Model Content

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

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

[0006] An agricultural technology seedling raising device includes a base plate. Vertical rods are fixedly connected to the four corners of the top of the base plate. Multiple trays are slidably fitted onto the circumferential surfaces of the four vertical rods. Each tray has a circular hole at each of its four corners that matches the vertical rod. Limiting mechanisms are provided at both ends of the bottom of each tray. Each limiting mechanism includes a rectangular frame located at the bottom of one end of the tray. Fixing blocks are fixedly connected to both ends of the outer wall of the rectangular frame. A single limiting rod is fixedly connected between two fixing blocks on the same side. Sliding sliders are slidably fitted onto the circumferential surfaces of both limiting rods. Each sliding slider has a circular hole that matches the limiting rod, and both sliding sliders are fixedly connected to the bottom of the tray. A spring is fitted onto the end of each limiting rod furthest from the center of the tray.

[0007] Preferably, the limiting mechanism further includes an inclined baffle fixedly connected to the outer end of the rectangular frame away from the center of the tray. A square rod is slidably sleeved on the other side of the rectangular frame, and a square hole adapted to the square rod is opened on the rectangular frame. A stop block is fixedly connected to one end of the square rod located inside the rectangular frame, and a handle is fixedly connected to the other end of the square rod. A limiting block is slidably sleeved in the middle of the square rod, and a square hole adapted to the square rod is opened on the limiting block. The limiting block is fixedly connected to the bottom of the tray. Through the setting of the limiting mechanism, the tray can rise freely when it rises, and when it falls, pulling the handle at one end of the two square rods can make the tray fall freely, which makes it convenient for the user to adjust the spacing of the tray.

[0008] Preferably, each of the trays has grooves at both ends near the inclined baffle, and the top two ends of the base plate are fixedly connected to U-shaped plates, with both U-shaped plates fitting into the grooves. Multiple stop bars are fixedly connected at equal intervals on the inner sides of the two U-shaped plates, and the stop bars fit into the inclined baffle.

[0009] Preferably, each of the trays has three placement slots on its top, and each placement slot is provided with a seedling box.

[0010] Preferably, a protective shell is fixedly connected to the top of the base plate, and a water pipe is provided on one side of the outer wall of the protective shell. Multiple branch pipes are fixedly connected at equal intervals on the circumferential surface of the water pipe. Multiple nozzles are fixedly connected to the other end of each branch pipe through the protective shell. Each nozzle is tilted downward. A solenoid valve is fixedly provided near the water pipe on each branch pipe. The setting of multiple solenoid valves allows the nozzles at the branch pipes to work independently.

[0011] Preferably, supplementary lights are fixedly connected to both sides of the inner wall of the protective shell via mounting brackets, an annular water collection groove is provided at the bottom of the base plate, and a drain pipe is fixedly connected to one side of the outer wall of the base plate, and the drain pipe is connected to the annular water collection groove.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. By employing technologies such as trays, U-shaped plates, baffles, and limiting mechanisms, the tray can move freely upwards during adjustment and retracts when the two handles are brought closer together downwards, causing the tray to descend. This also facilitates the removal and addition of trays, effectively solving the problem of inconvenient tray adjustment mentioned in the background technology. This achieves efficient and convenient tray adjustment for the seedling raising device, allowing operators to easily and quickly adjust the tray position according to seedling needs, reducing manpower and time costs. Furthermore, it allows for flexible adjustment of the number of seedling layers and spatial layout based on the number of seedlings and their growth stage, improving space utilization.

[0014] 2. The design incorporates branch pipe nozzles, solenoid valves, and annular water collection troughs, allowing for the selection of appropriate branch pipe nozzles for regular watering based on the location of the tray and seedling box, thus facilitating seedling growth.

[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figures 1-4An agricultural technology seedling raising device includes a base plate 1. Vertical rods 6 are fixedly connected to the four corners of the top of the base plate 1. Multiple trays 7 are slidably fitted on the circumferential surfaces of the four vertical rods 6. Each tray 7 has a circular hole at each of the four corners that matches the vertical rod 6. Each tray 7 has a limiting mechanism 9 at both ends of its bottom. The limiting mechanism 9 includes a rectangular frame 901 located at the bottom of one end of the tray 7. Fixing blocks 903 are fixedly connected to both ends of the outer wall of the rectangular frame 901. A limiting rod 904 is fixedly connected between two fixing blocks 903 on the same side. Sliding sliders 906 are slidably fitted on the circumferential surfaces of the two limiting rods 904. Circular holes that match the limiting rods 904 are opened on the two sliders 906. Both sliders 906 are fixedly connected to the bottom of the tray 7. A spring 905 is fitted on the end of the two limiting rods 904 away from the center of the tray 7.

[0022] In this utility model, the limiting mechanism 9 also includes an inclined baffle 902 fixedly connected to one end of the rectangular frame 901 away from the center of the tray 7. A square rod 907 is slidably sleeved on the other side of the rectangular frame 901, and a square hole adapted to the square rod 907 is opened on the rectangular frame 901. A stop block is fixedly connected to one end of the square rod 907 located inside the rectangular frame 901, and a handle is fixedly connected to the other end of the square rod 907. A limiting block 908 is slidably sleeved in the middle of the square rod 907, and a square hole adapted to the square rod 907 is opened on the limiting block 908. The limiting block 908 is fixedly connected to the bottom of the tray 7.

[0023] In this utility model, each tray 7 has a groove at both ends near the inclined baffle 902. The top two ends of the base plate 1 are fixedly connected to U-shaped plates 10, and both U-shaped plates 10 are adapted to the groove. Multiple stop rods 1001 are fixedly connected at equal distances on the inner side of the two U-shaped plates 10, and the stop rods 1001 are adapted to the inclined baffle 902. The multiple stop rods 1001, together with the inclined baffle 902, can support the tray 7.

[0024] In this utility model, each tray 7 has three placement slots on its top, and each placement slot is equipped with a seedling box 8. Each seedling box 8 also has a label on its front end for easy labeling of the seedling variety.

[0025] In this utility model, a protective shell 3 is fixedly connected to the top of the base plate 1, and a water pipe 4 is provided on one side of the outer wall of the protective shell 3. Multiple branch pipes 401 are fixedly connected at equal intervals on the circumferential surface of the water pipe 4. The other end of each branch pipe 401 passes through the protective shell 3 and is fixedly connected to multiple nozzles 402. Each nozzle 402 is tilted downward. A solenoid valve 403 is fixedly provided near the water pipe 4 on each branch pipe 401. By setting the solenoid valve 403, the water supply of each branch pipe 401 can be controlled, so that the nozzles 402 of each branch pipe 401 can work independently.

[0026] In this utility model, supplementary lights 5 are fixedly connected to both sides of the inner wall of the protective shell 3 by mounting brackets. An annular water collection trough 101 is opened at the bottom of the base plate 1, and a drain pipe 2 is fixedly connected to one side of the outer wall of the base plate 1. The drain pipe 2 is connected to the annular water collection trough 101. The annular water collection trough 101 can collect and discharge excess water sprayed from the nozzle 402.

[0027] Working Principle: When using this seedling raising device, the top of water pipe 4 is connected to the water supply pipe to ensure water supply to each branch pipe 401 and nozzle 402. When adjusting the height of adjacent trays 7 according to the type of seedling, simply push the tray 7 upwards. During this upward push, the two inclined baffles 902 at the bottom of each tray 7 have inclined surfaces at their contact points with the adjacent stop rods 1001. As the tray 7 rises with the inclined baffles 902, the inclined baffles 902 and the rectangular frame 901 compress the spring 905. During this process, the square rods 907 slide within the rectangular frame 901, and the two square rods 907 do not move. When the desired height is reached, the inclined baffles 902 extend under the action of the spring 905 and contact the bottom stop rods 1001. To prevent the inclined baffle 902 from retracting, when the tray 7 is moved downwards, the two handles at the bottom of the tray 7 are pulled together, causing the rectangular frame 901 to be pulled by the square rod 907 and the stop block, thus retracting the inclined baffle 902. At the same time, the spring 905 is compressed, allowing the tray 7 to move freely downwards. The tray 7 can also be removed from or installed from the top of the vertical rod 6 as needed, thereby adjusting the number of trays 7. When seedlings are being raised in the seedling box 8 at the top of the tray 7, the user can periodically select the appropriate position of the solenoid valve 403 to open, allowing the sprinkler 402 to irrigate the seedlings. Excess water is collected through the annular water collection trough 101 and discharged through the drain pipe 2. Supplemental lighting is provided to the seedlings through the supplemental lights 5 on both sides, improving their growth rate.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
