Specific embodiments

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0026] Please refer to Figures 1 to 3 , the present invention provides a technical solution:

[0027] A corn cultivation and seedling raising device, comprising a bracket 1, the upper end of the bracket 1 is fixedly connected with a water storage tank 2, the upper end of the water storage tank 2 is provided with a water inlet 21, the lower end of the water storage tank 2 is provided with a watering component 3, and the number of the watering components 3 is two. The watering component 3 includes a fixed block 31 fixedly connected to the lower end of the water storage tank 2. Both the front and rear sides of the fixed block 31 are provided with sliding grooves 311. Both of the two sliding grooves 311 are movably connected with sliders 322. A round block 321 is fixedly connected between the two sliders 322. The lower end of the round block 321 is fixedly connected with a support block 32. Both of the two fixed blocks 31 are internally fixedly connected with a hose 4. Both of the two hoses 4 penetrate into the water storage tank 2. A control switch 41 is fixedly connected to the outer part of the hose 4, and the control switch 41 penetrates to the outside of the fixed block 31. The lower ends of the two hoses 4 are fixedly connected with a liquid distribution pipe 42. A water delivery pipe 43 is fixedly connected between the two liquid distribution pipes 42. A spray head 431 is fixedly connected to the outer part of the water delivery pipe 43, and the number of the spray heads 431 is multiple. All of the multiple sliding grooves 311 are inclined. All of the multiple sliders 322 are slidably fitted inside the sliding grooves 311. The sum of the elastic forces of the multiple springs 521 is greater than the sum of the gravity of the cultivation tray 6 and the two support blocks 32. All of the multiple round holes 61 are slidably fitted outside the round rod 52.

[0028] By adopting the above technical solution, before carrying out the corn cultivation and seeding work, first, it is necessary to fill the water storage tank 2 with water through the water inlet 21. Then, the cultivation tray 6 and its internal components are placed by aligning the multiple round holes 61 with the multiple round rods 52. Subsequently, the support blocks 32 are placed into the upper end of the sliding groove 311 through the sliders 322, so that the lower ends of the multiple support blocks 32 contact the upper end of the cultivation tray 6. At this time, by rotating and activating the control switch 41, the water inside the water storage tank 2 flows out through the hose 4 to the liquid distribution pipe 42, then flows through the liquid distribution pipe 42 into the water delivery pipe 43, and finally, irrigation work is carried out through the nozzles 431 outside the water delivery pipe 43. At this time, the seedlings and the substrate soil inside the placement groove 62 absorb sufficient water, and the excess water flows out through the leakage grooves 621 inside the placement groove 62. The increased weight of the components inside the cultivation tray 6 causes the multiple springs 521 to be further compressed, and the components such as the cultivation tray 6 move downward, driving the support blocks 32 at the upper end of the cultivation tray 6 to move downward. The downward movement of the support blocks 32 moves inward toward the fixed block 31 through the cooperation between the sliders 322 and the sliding groove 311, so that the round blocks 321 at the upper ends of the support blocks 32 continuously squeeze and clamp the hose 4, thereby stopping the irrigation work. When the water inside the seedlings and the substrate soil is completely absorbed and evaporated, the weight of the substrate soil and the seedlings inside the cultivation tray 6 decreases. With the decrease in weight, at this time, the elastic force of the multiple springs 521 is greater than the gravity of the components such as the cultivation tray 6, causing the components such as the cultivation tray 6 to move upward. The upward movement of the cultivation tray 6 drives the upper support blocks 32 and the round blocks 321 to move upward along the sliding groove 311 together. The upward movement of the round blocks 321 causes the round blocks 321 to move away from the hose 4, so that the water inside the water storage tank 2 is irrigated through the hose 4, thereby achieving the purpose of automatically irrigating the corn seedlings by reducing the mass of the substrate soil, and thus improving the survival rate of the corn seedlings.

[0029] Specifically, as Figure 4 shown, a water basin 5 is fixedly connected to the middle of the bracket 1. A top block 51 and round rods 52 are fixedly connected inside the water basin 5, and the number of the round rods 52 is four. The number of the top blocks 51 is multiple. Springs 521 are movably connected to the outside of the four round rods 52. The upper end of the water basin 5 is movably connected to a cultivation tray 6. Round holes 61 are formed around the upper end of the cultivation tray 6. A placement groove 62 is formed inside the cultivation tray 6, and the number of the placement grooves 62 is multiple. Leakage grooves 621 are formed on the inner walls of the multiple placement grooves 62. Bottom plates 63 are movably connected inside the multiple placement grooves 62. The inner walls of the multiple placement grooves 62 are all inclined, and the multiple bottom plates 63 are all slidably attached to the inside of the multiple placement grooves 62.

[0030] By adopting the above technical solution, when it is necessary to transplant the seedlings inside the cultivation tray 6 after the corn cultivation and seeding are completed, first, the two support blocks 32 need to be lifted upward so that the sliders 322 leave the inside of the chute 311. Secondly, the operator needs to press the left and right sides of the upper end of the cultivation tray 6 with both hands. By pressing, the cultivation tray 6 compresses the spring 521 and tightens it. Then, as the components such as the cultivation tray 6 descend, the lower end of the bottom plate 63 inside the placement groove 62 contacts the corresponding top block 51 inside the water basin 5. By continuously pressing down, the top block 51 pushes the bottom plate 63 and the upper seedling roots and the substrate soil to move upward together. Then, by pressing the middle part of the upper end of the cultivation tray 6, the seedlings inside the multiple placement grooves 62 are completely pushed out. At this time, the operator then holds the lower end of the cultivation tray 6 with hands and moves upward, so that the round hole 61 leaves the outside of the round rod 52, and then the transplantation work is carried out, so as to achieve the purpose of easily separating the substrate soil and the seedling roots from the cultivation tray 6, thereby avoiding damage to the corn seedlings and improving the quality of the corn seedlings.

[0031] Working principle: By rotating and starting the control switch 41, the water inside the water storage tank 2 flows out through the hose 4 to the distribution pipe 42, then flows through the distribution pipe 42 into the water delivery pipe 43, and finally, irrigation work is carried out through the nozzle 431 outside the water delivery pipe 43. At this time, the seedlings and the substrate soil inside the placement groove 62 absorb enough water, and the excess water flows out through the leakage groove 621 inside the placement groove 62. As the weight of the components such as the cultivation tray 6 inside increases, multiple springs 521 are further compressed. Then, the components such as the cultivation tray 6 move downward, driving the support block 32 at the upper end of the cultivation tray 6 to move downward. The downward movement of the support block 32 moves inward toward the fixed block 31 through the cooperation between the slider 322 and the chute 311, so that the round block 321 at the upper end of the support block 32 continuously squeezes and clamps the hose 4, thereby stopping the irrigation work. When the water inside the seedlings and the substrate soil is completely absorbed and evaporated, the weight of the substrate soil and the seedlings inside the cultivation tray 6 decreases. As the weight decreases, at this time, the elastic force of the multiple springs 521 is greater than the gravity of the components such as the cultivation tray 6, so that the components such as the cultivation tray 6 move upward. The upward movement of the cultivation tray 6 drives the upper support block 32 and the round block 321 to move upward along the chute 311 together. As the round block 321 moves upward, the round block 321 moves away from the hose 4, so that the water inside the water storage tank 2 is irrigated through the hose 4, thereby achieving the purpose of automatically irrigating the corn seedlings by reducing the quality of the substrate soil, and improving the survival rate of the corn seedlings.
