Description

Technical Field

[0001] This utility model belongs to the field of rice seedling cultivation, specifically relating to a bottomless rice seedling tray for rice planting. Background Technology

[0002] Bottomless rice seedling trays are an innovative rice seedling raising tool. They are designed and improved based on traditional rice seedling trays, removing the bottom soil and using other methods (such as hydroponics or soilless cultivation techniques) to support the growth of seedlings.

[0003] Most existing bottomless rice seedling trays have a simple structure. The culture solution or culture water is often consumed during the rice growth process, such as by the rice growth and absorption, and by the normal evaporation of the culture solution. These situations will cause the water level of the culture solution to drop, making it difficult for the rice seeds to come into contact with the culture solution, thus affecting their normal growth. This further leads to the need for regular replenishment of the culture solution, increasing the labor cost of rice cultivation. In addition, the traditional exposed rice cultivation method is also more likely to attract external pests to eat the rice seedlings, and there is also the problem of foreign objects crushing the rice seedlings.

[0004] Therefore, in response to the problems that existing bottomless rice seedling trays often require manual replenishment of culture medium during use and are easily damaged by external pests, diseases, and foreign objects, a bottomless rice seedling tray for rice cultivation has been developed. By adding an automatic culture medium replenishment structure and an insect-proof and pressure-proof cover structure to the bottomless rice seedling tray, the convenience of using the bottomless rice seedling tray can be effectively improved, and the quality and effect of rice seed cultivation can be enhanced. Utility Model Content

[0005] To overcome the problems that existing bottomless rice seedling trays often require regular manual replenishment of culture medium during use, and are easily damaged by external pests, diseases, and foreign objects.

The control computer is installed at the upper end of the detection box. An electric water valve is fixedly connected in the second mounting groove. A radar water level sensor is fixedly connected in the first mounting groove. The seedling tray is set on the upper inner wall of the nutrient box. Several sets of seedling holes are evenly distributed through the upper and lower ends of the seedling tray. Seedling hoppers are fixedly connected to the lower inner wall of the seedling holes. A protective frame is movably set at the upper edge of the nutrient box. Front and back insect-proof nets, left and right insect-proof nets and top insect-proof nets are respectively installed through the front and back, left and right, and top of the protective frame.

[0007] Preferably, a storage box is installed on the left side of the testing box, and one end of a connecting pipe is installed on the upper end of the storage box, with the other end of the connecting pipe installed on an electric water valve.

[0008] Preferably, the upper outer wall of the seedling tray is fixed with an extended side frame, and the lower edge of the protective frame is provided with symmetrically distributed limiting grooves.

[0009] Preferably, the upper end of the extension frame is fixed with handles that are symmetrically distributed on the left and right, and the limiting groove is adapted to the handles.

Detailed Implementation

[0025] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0026] Please see Figures 1-7 This utility model provides an embodiment: a bottomless rice seedling tray for rice cultivation, including a nutrient box 1 and a seedling tray 4, and also including a protective frame 3, an electric water valve 8, a radar water level sensor 9 and a control computer 10. A detection box 2 is fixed to the left end of the nutrient box 1. The upper end of the detection box 2 has a second mounting groove 7 and a first mounting groove 6 distributed front and back. The control computer 10 is installed at the upper end of the detection box 2. The electric water valve 8 is fixed in the second mounting groove 7 and the radar water level sensor 9 is fixed in the first mounting groove 6. The seedling tray 4 is set on the upper inner wall of the nutrient box 1. Several sets of seedling holes 14 are evenly distributed through the upper and lower ends of the seedling tray 4. Seedling hoppers 15 are fixed to the lower inner wall of the seedling holes 14. A protective frame 3 is movably set at the upper edge of the nutrient box 1. Front and back insect-proof nets 16, left and right insect-proof nets 19 and top insect-proof nets 18 are respectively installed through the front and back, left and right, and top of the protective frame 3.

[0027] The radar water level sensor 9 monitors the water level of the culture medium in the nutrient tank 1 in real time. When the water level of the culture medium falls below the set standard water level, the control computer 10 activates the electric water valve 8 and the water pump in the storage tank 5 to transport the stored culture medium into the nutrient tank 1 to replenish the daily consumption of the culture medium. This ensures that the culture medium can always maintain a suitable water level for cultivating rice seeds. The protective cover, composed of the protective frame 3 and the front and rear insect-proof nets 16, the top insect-proof net 18, and the left and right insect-proof nets 19, can provide a covering-style insect-proof and pressure-proof protection for the rice seeds cultivated in the seedling tray 4, thereby improving the effect and quality of rice cultivation.

[0028] Please see Figure 3 In this embodiment, a storage box 5 is installed on the left end of the detection box 2, and a connecting pipe 11 is installed on the upper end of the storage box 5. The other end of the connecting pipe 11 is installed on the electric water valve 8. The electric water valve 8 can be controlled by the control computer 10 to transport the culture medium into the nutrient box 1 to provide suitable water level for the rice seedlings to grow, based on the water level information fed back by the radar water level sensor 9.

[0029] Please see Figures 5-7 In this embodiment, an extension frame 13 is fixedly attached to the upper outer wall of the seedling tray 4, and a limiting groove 17 is provided at the lower edge of the protective frame 3. The extension frame 13 can limit the seedling tray 4 to be installed on the upper inner wall of the nutrient box 1, so that the roots of the rice seeds can contact the culture solution. A handle 12 is fixedly attached to the upper end of the extension frame 13. The limiting groove 17 is adapted to the handle 12. The handle 12 can facilitate the user to take out the cultivated rice seeds together with the seedling tray 4.

[0030] Please see Figures 3-6 In this embodiment, the control computer 10 is located between the first mounting slot 6 and the second mounting slot 7. The control computer 10 is electrically connected to the electric water valve 8 and the radar water level sensor 9. The control computer 10 can control the electric water valve 8 and the radar water level sensor 9. The detection box 2 is connected to the nutrient box 1. The lower end of the radar water level sensor 9 does not contact the lower inner wall of the detection box 2. The radar water level sensor 9, which does not contact the lower inner wall of the detection box 2, can ensure the accuracy of the radar water level sensor 9 in monitoring the nutrient solution water level. The front and rear insect-proof nets 16, the top insect-proof net 18, and the left and right insect-proof nets 19 are all metal mesh. The seedling hole 14 is connected to the seedling hopper 15. The front and rear insect-proof nets 16, the top insect-proof net 18, and the left and right insect-proof nets 19, which are made of metal mesh, can effectively prevent external pests from affecting the normal growth of rice seedlings inside the protective frame 3.

[0031] When using it, first pour the culture solution into the nutrient tank 1 and put the culture solution into the storage tank 5. Then put the rice seeds into the seedling hole 14. The rice seeds will roll along the seedling hole 14 into the seedling hopper 15. Then install the seedling tray 4 containing the rice seeds onto the upper inner wall of the nutrient tank 1. The extension side frame 13 limits and fixes the seedling tray 4 on the nutrient tank 1 so that the rice seeds come into contact with the culture solution in the nutrient tank 1.

[0032] Then, the protective frame 3 is installed on the outer wall of the handle 12 on the extension frame 13 to provide a covering-type insect and pressure protection for the rice seeds cultivated in the seedling tray 4 through the protective frame 3 and the front and rear insect-proof nets 16, the top insect-proof net 18, and the left and right insect-proof nets 19.

[0033] During the rice seed cultivation process, the radar water level sensor 9 monitors the water level of the culture solution flowing from the nutrient tank 1 to the detection tank 2 in real time. This information is then fed back to the control computer 10, which analyzes the data. If the water level of the culture solution falls below the set standard level, the control computer 10 activates the electric water valve 8 and the water pump in the storage tank 5 to transport the stored culture solution back to the nutrient tank 1 to replenish the daily consumption of the culture solution. This ensures that the culture solution maintains a suitable water level for rice seed cultivation.

[0034] Through the above steps, the water level of the culture solution in the nutrient tank 1 is detected in real time by the radar water level sensor 9. When the water level of the culture solution is lower than the set standard water level, the control computer 10 starts the electric water valve 8 and the water pump in the storage tank 5 to transport the stored culture solution to the nutrient tank 1 to replenish the daily consumption of the culture solution. This ensures that the culture solution can always maintain a suitable water level for cultivating rice seeds. The protective cover composed of the protective frame 3 and the front and rear insect-proof nets 16, the top insect-proof net 18, and the left and right insect-proof nets 19 can provide a covering-type insect-proof and pressure-proof protection for the rice seeds cultivated in the seedling tray 4, thereby improving the effect and quality of rice cultivation. This solves the problem that existing bottomless rice seedling trays often require manual replenishment of the culture solution during use and are easily damaged by external pests and foreign objects.

[0035] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
