Technical Field

[0001] The utility model relates to the technical field of rice seedling cultivation, and more specifically, to a rice seedling cultivation device. Background Art

[0002] As one of the most important food crops in the world, the development of rice cultivation technology and equipment is of great significance to increasing yield, improving quality and reducing production costs. When cultivating rice seedlings, it is necessary to use a rice seedling raising device.

[0003] However, the conventional seedling raising device cannot realize convenient seedling raising operation when the seedlings need to be raised after they have grown, and the existing seedling raising device cannot insulate the seedlings in cold weather when planting early rice, which affects the raising effect of different rice seedlings.

[0004] After searching, a Chinese patent with publication number CN220476412U discloses a rice seedling raising device. This structure sows rice seeds inside a seedling raising tray, and through the design of a heat-insulating and insect-proof cover above the seedling raising tray, the seedlings can be kept warm in cold weather, thereby improving the use effect. Through the design of the plug-in board, the overlapping open state of the first air hole and the second air hole can be controlled to meet the breathing effect of the seedlings inside the seedling raising tray. Through the coordinated design of the top contact piece and the planting tray, when lifting the seedlings, the top contact piece can be pulled to quickly lift the seedlings inside the seedling raising tray, and when lifting the seedlings, they can be picked up together with the planting soil, thereby improving the convenience of lifting the seedlings.

[0005] However, when this structure is actually used, since the seedlings need good light when they are cultivated, when the device is placed outside, the air holes on the device are easily clogged with dust, which is difficult to handle and affects the ventilation effect of seedling cultivation. In addition, it is difficult to collect and reuse the moisture of the seedlings by directly discharging it. In view of this, the utility model proposes a seedling raising device for rice cultivation. Utility Model Content

[0006] In order to overcome the above defects of the prior art, the utility model provides a rice seedling raising device for rice cultivation to solve the problems raised in the above background technology.

Each time the heat preservation cover 7 is slid open and closed, the cleaning brush 12 is attached to the surface of the air hole 5 for cleaning, thereby avoiding clogging of the surface of the air hole 5, which is difficult to handle and affects the ventilation effect of the seedlings.

[0030] In a specific embodiment, as shown in the attached Figure 1 As shown, a collecting box 13 is arranged at the bottom of one end of the seedling raising box 1, and two filter screens 14 with different apertures are arranged in sequence from top to bottom inside the collecting box 13, and a mounting groove is arranged on the surface of the collecting box 13, and a sealing plate 15 is installed inside the mounting groove. The sealing plate 15 is installed inside the mounting groove by screws, and one end of the two filter screens 14 are connected to the sealing plate 15, and one end of the collecting box 13 is provided with an output pipe 16 with a flange.

[0031] Specifically, in this structure, the excess water inside the seedling raising box 1 is discharged through the drain pipe 6 and then enters the inside of the collecting box 13. The collecting box 13 can collect the discharged water to avoid water waste and can be reused. The water falling into the collecting box 13 is filtered layer by layer through the filter screens 14 with different filter holes distributed up and down. The operator can use the extraction pump to extract the water inside the collecting box 13 through the output pipe 16 to achieve the reuse of water.

[0032] When the filter screen 14 needs to be cleaned, the screws on the sealing plate 15 can be released, and the sealing plate 15 can be pulled out from the inside of the installation groove, and the filter screen 14 can be pulled out from the inside of the collection box 13 for cleaning.

[0035] Working principle of this utility model:

[0036] When the above structure is used, the planting soil is first spread on the seedling raising net plate 2, the rice seeds are sown on the planting soil, and the planting soil is watered and fertilized. The protective cover 4 is installed on the top of the seedling raising box 1 to protect the rice seeds and prevent pests and birds from affecting the rice seeds. The air holes 5 on the surface of the protective cover 4 can flow air to the seedlings to meet the breathing effect of the seedlings, and the drainage pipe 6 can discharge the excess water inside the seedling raising box 1;

[0037] The protective cover 4 and the heat-insulating cover 7 are both made of acrylic plates, which can achieve the effect of light transmission and realize the light absorption of the seedlings. When the seedlings need to be ventilated, the heat-insulating cover 7 can be opened to allow the air holes 5 on the surface of the protective cover 4 to leak out. When the seedlings need to be insulated and protected in rain or extreme weather, the heat-insulating cover 7 can be slidably installed on the top of the heat-insulating cover 7 for heat insulation and protection. When opening and closing the heat-insulating cover 7, the slider 9 at the bottom can slide inside the slide groove 8. At the same time, the operator can rotate the adjusting block 10 to make the screw 11 and the heat-insulating cover 7 threadedly rotate, and move the cleaning brush 12 inside the heat-insulating cover 7 to the air holes 5 on the surface of the protective cover 4. Then, each time the heat-insulating cover 7 is slid open and closed, the cleaning brush 12 is attached to the surface of the air holes 5 for cleaning, thereby avoiding clogging of the surface of the air holes 5, which is difficult to handle and affects the ventilation effect of the seedlings.

[0038] The excess water inside the seedling raising box 1 is discharged through the drain pipe 6 and enters the interior of the collecting box 13. The collecting box 13 can collect the discharged water to avoid wasting water and can be reused. The water falling into the collecting box 13 is filtered layer by layer through the filter screens 14 with different filter holes distributed up and down. The operator can use the extraction pump to extract the water inside the collecting box 13 through the output pipe 16 to achieve the reuse of the water. When it is necessary to clean the filter screen 14, the screws at the sealing plate 15 can be released, and the sealing plate 15 can be pulled out from the inside of the installation groove, and the filter screen 14 can be pulled out from the inside of the collecting box 13 for cleaning.

[0039] When performing the seedling lifting operation, the damping shaft 18 is driven to rotate inside the damping bearing through the rotating block 20, and the lifting rod 19 is rotated from a horizontal state to a vertical state. The lifting rod 19 in the vertical state can slide the seedling raising net plate 2 upward slightly to lift it up, thereby facilitating the operator to perform the seedling lifting operation.

[0040] The above description is only a preferred embodiment of the present invention and 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 in the protection scope of the present invention.
