Technical Field

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

[0002] Rice seedling raising equipment is a professional instrument designed specifically for rice seedling cultivation. Its core function is to create suitable and stable environmental conditions for rice seed germination and seedling growth, covering key elements such as temperature, humidity, light, and soil nutrients. It can significantly improve the efficiency and quality of rice seedling raising, and also ensure that the seedlings grow uniformly and robustly, laying a solid foundation for subsequent field transplanting and achieving high yields and bumper harvests, and effectively reducing the interference of adverse external factors on the seedlings.

[0003] Currently, common seedling raising devices include seedling boxes. Inside the seedling box, multiple support plates are stacked vertically, and each support plate contains a petri dish. A water spray system is installed at the top of the seedling box. Although each support plate has drainage holes, uneven water distribution still exists when water is sprayed onto the petri dishes. Specifically, the uppermost support plate has the most water, while the lowermost support plate has relatively little water. This difference in water volume negatively impacts the growth of rice seedlings at different heights. Utility Model Content

[0004] The purpose of this invention is to provide a rice seedling box with a flexible structure, in which planting racks at different positions alternately contact the spray nozzles, thus avoiding the impact of water volume differences on seedling growth.

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.

[0022] Example 1

[0023] The rice seedling box described in this embodiment, such as Figures 1 to 6 As shown, the box 1 is horizontally arranged. A box door 11 is installed on the left side wall of the box 1. A through groove is opened on the left side wall of the box 1. The rear end of the box door 11 is hinged in the through groove. The box door 11 is opened to take out and put in the seedlings. When the box door 11 is closed, it isolates the seedlings from the outside world and reduces the impact of external factors on the growth of the seedlings.

[0024] A central shaft 4 is horizontally installed in the middle of the box 1;

[0025] A drive unit for driving the central shaft 4 to rotate is installed on the rear side wall of the housing 1. The drive unit is installed on the rear side wall of the housing 1, and the rear end of the central shaft 4 is connected to the power output end of the drive unit. The drive unit is existing technology and generally adopts a servo motor. The servo motor drives the central shaft 4 to rotate, so that the culture baskets 18 at different positions alternately approach the nozzle 3.

[0026] Several sets of connecting parts are fixed on the central shaft 4 in a circular arrangement centered on the central shaft 4. Each connecting part includes two connecting rods 10, which are fixed at the front and rear ends of the central shaft 4 respectively. The two connecting rods 10 are located on the same horizontal plane. A fixing rod 16 is horizontally fixed to the movable end of each connecting rod 10, positioned horizontally between the two connecting rods 10. The front end of the fixing rod 16 is fixed to the movable end of the front connecting rod 10, and the rear end is fixed to the movable end of the rear connecting rod 10. A sleeve 15 is fitted onto the fixing rod 16, and the sleeve 15 rotates around the fixing rod 16. Hooks 13 are installed on each of the pad blocks 17. There are four hooks 13, each... Fixed to the top of pad 17; each hook 13 is suspended by a traction rope 14, the movable end of the traction rope 14 is fixed to the sleeve 15, the number of traction ropes 14 matches the number of hooks 13, one end of the traction rope 14 is fixed to the sleeve 15, and the other end is suspended on the corresponding hook 13. When the connector is in use, the movable ends of the four traction ropes 14 are suspended on the hooks 13. The length of each traction rope 14 is the same, so that the base plate 12 is horizontally set below the connecting rod 10. When the connecting rod 10 rotates, the sleeve 15 rotates around the fixed rod 16. With the help of the gravity of the base plate 12, the base plate 12 is kept horizontal when the connecting rod 10 rotates. There are multiple sets of connectors, which are evenly distributed in a circle with the central axis 4 as the center, and are used to install multiple seedling components.

[0027] The bottom plate 12 has several drainage holes that are connected vertically. The bottom plate 12 is horizontally set below each set of connectors. Excess water on the planting rack 19 flows to the bottom of the box 1 through the drainage holes, avoiding excessive water accumulation in the cultivation basket 18. This prevents the soil from becoming too wet due to excessive water accumulation, which would prevent the roots from absorbing water and nutrients properly and thus affect the normal growth of rice.

[0028] Four pads 17 are installed at the four corners of the base plate 12, and the bottom of each pad 17 is fixed to the four corners of the base plate 12. A planting rack 19 is horizontally installed on the top of the base plate 12. The planting rack 19 has a cross-shaped structure and is inserted into the pads 17, overlapping with the base plate 12. When transplanting seedlings, the planting rack 19 is simply removed from the pads 17. Several cultivation baskets 18 are installed inside the planting rack 19. Several insertion holes are opened on the planting rack 19, and the cultivation baskets 18 are inserted into the insertion holes independently. The cultivation baskets 18 provide soil and nutrients for seedling growth. The whole unit constitutes a seedling raising component for planting rice seedlings. When using the seedling raising component, the seedlings are planted into the cultivation baskets 18. Several cultivation baskets 18 are installed on the top of the base plate 12 through the planting rack 19. The water accumulated on the planting rack 19 flows into the box 1 through the drainage hole. The planting rack 19 is removed from the pad 17 to facilitate the transplanting of seedlings. Of course, in the seedling raising component, the width of the planting rack 19 is greater than the width of the base plate 12, so that the left and right sides of the planting rack 19 extend beyond the base plate 12, which is conducive to the planting rack 19 being inserted into the pad 17 when it is installed, and also makes it easy to remove the planting rack 19 from the pad 17.

[0029] Water pipe 2 is installed on the top of the box 1. Spray nozzle 3 is installed on the water pipe 2 to spray water on the rice seedlings. The water pipe 2 is installed horizontally on the top of the box 1. The spray nozzle 3 is installed at the bottom of the water pipe 2. Water is sprayed on the seedlings through the spray nozzle 3 to provide the water needed during the growth process. A water tank is installed on the rear side wall of the box 1 to supply water to the water pipe 2.

[0030] Working principle:

[0031] Seedlings are placed in the cultivation basket 18, and the cultivation basket 18 is inserted into the planting rack 19. The planting rack 19 is then inserted into four pad blocks 17 and stacked on top of the base plate 12. The movable ends of the traction ropes 14 are suspended from the hooks 13, so that the planting rack 19 is horizontally positioned below the connecting rod 10. Water is sprayed onto the seedlings through the nozzle 3. The central shaft 4 is rotated by the drive component, driving the planting rack 19 to make circular motion within the box 1, so that the cultivation baskets 18 in different positions alternately approach the nozzle 3. When the planting rack 19 rotates, the sleeve 15 rotates around the fixed rod 16. The lengths of the traction ropes 14 are equal, and with the gravity of the planting rack 19, the planting rack 19 remains horizontal when rotating, so that the seedlings in each planting rack 19 can come into contact with water, avoiding the situation where a large amount of water accumulates or there is no water in a certain planting rack 19.

[0033] This embodiment further illustrates the technology, such as Figure 1As shown, a water collection tank 7 is installed at the bottom of the box 1, and a filter screen 9 is horizontally fixed at the top of the water collection tank 7. The water collection tank 7 is horizontally installed at the bottom of the box 1, and the filter screen 9 is horizontally fixed on the water collection tank 7. The clean water flowing out of the bottom plate 12 and leaking from the nozzle 3 is filtered by the filter screen 9 and collected into the water collection tank 7.

[0034] A water pump 8 is installed in the water collection tank 7. A water delivery pipe 5 is vertically fixed to the outlet end of the water pump 8. The water pump 8 is a submersible pump. The inlet end of the water pump 8 is located in the water collection tank 7, and the outlet end of the water pump 8 is connected to the lower end of the water delivery pipe 5.
