[0002] A tidal irrigation seedbed is an efficient water-saving irrigation system designed based on the principle of tidal ebb and flow, and is widely used in agricultural seedling raising and plant cultivation. Its core feature is that by periodically injecting water into and draining water from the seedbed, the plant roots can achieve a balance between water and oxygen, thereby promoting healthy growth;
[0003] Chinese Patent Publication No.: CN212786844U discloses a tidal irrigation seedbed for water conservancy green projects, including a device bottom plate. Two side plates are fixedly installed on the top of the device bottom plate. A seedbed body is arranged inside the two side plates. A planting pot body is placed on the top of the seedbed body. A threaded sleeve ring is fixedly sleeved inside the seedbed body. A threaded column is threadedly connected inside the threaded sleeve ring. A collection plate is arranged below the seedbed body. A second drain pipe is arranged on the bottom surface of the collection plate; this tidal irrigation seedbed for water conservancy green projects can use the first drain pipe and the first drain holes to convey the accumulated liquid to the top of the collection plate, facilitating the timely treatment of the accumulated liquid. With the arrangement of the second drain pipe and the hose at the bottom of the collection plate, the accumulated liquid can be pumped and conveyed into the top pipe by a delivery pump, and sprayed by the spray pipe at the bottom of the top pipe, achieving the effect of recycling the accumulated liquid on the top of the seedbed body;

[0036] Please refer to Figures 1-9 As shown, this embodiment provides a tidal irrigation seedbed for a water conservancy green project, including an outer protective shell 1 and a support plate 4.

The fixed column 52 is fixedly connected to the inner wall of the outer protective shell 1, and the two fixed columns 52 are fixedly connected through the support plate 4. A sliding column 521 is slidably connected to the top of the fixed column 52, and a rotating column 54 is rotatably connected to the outer side of the sliding column 521.
[0037] As Figure 4 shown, a first rotating rod 151 is rotatably connected through the vertical plate 15. First gears 152 are fixedly connected to the outer walls of both ends of the first rotating rod 151. The first gears 152 are meshed with the racks 14. One end of the first rotating rod 151 is fixedly connected with an annular handle 153, and the annular handle 153 is located outside the vertical plate 15.
[0038] As Figures 5-6 shown, water outlets 21 are opened at the top of both sides of the water storage layer 2, a plurality of arched grooves 31 are opened on the outer walls of both sides of the seedbed 3, and strip-shaped grooves for the outer wall of the water storage layer 2 to slide are opened at the bottom of both sides of the seedbed 3.
[0039] As Figures 5-8As shown in the figure, a motor 51 is fixedly connected to the outer wall of the outer protective shell 1. The output end of the motor 51 is fixedly connected to a threaded rod 511. One end outer wall of the threaded rod 511 near the motor 51 is sleeved with a first transmission belt 512 through a pulley. The threaded rod 511 is rotatably connected to the inside of the fixed column 52. A sliding column 521 is threadedly connected to the threaded rod 511. Cross plates 523 are fixedly connected to the inside of both sides of the fixed column 52. One end of the cross plate 523 away from the fixed column 52 is fixedly connected to a slide rail 5231. A sliding plate 53 is slidably connected between the two slide rails 5231. The middle end of the sliding plate 53 is fixedly connected to a communication pipeline 531. The communication pipeline 531 is communicated with the water tank 13. The two water tanks 13 are communicated with each other. The two sliding columns 521 penetrate and are rotatably connected to a second rotating rod 522. A rotating column 54 is fixedly connected to the end of the second rotating rod 522. A square groove 541 is formed on one side of the rotating column 54 away from the sliding column 521. An arched hole 542 is formed inside the square groove 541. A first slider 543 and a second slider 544 are slidably connected to the inside of the rotating column 54. A telescopic rod 5431 is fixedly connected between the first slider 543 and the second slider 544. A spring 5441 is fixedly connected to one side of the second slider 544 away from the telescopic rod 5431. One end of the spring 5441 away from the second slider 544 is fixedly connected to the inner wall of the rotating column 54. A protruding column 5442 is fixedly connected to one side of the second slider 544 close to the arched hole 542. The protruding column 5442 is slidably connected in the arched hole 542 and is also slidably connected in the arched groove 31.
[0040] Among them: The telescopic rod 5431 is a passive expansion and contraction formed by the sliding and mutual extrusion of the first slider 543 and the second slider 544 driven by the rotation of the connecting rod 55.
[0041] As Figures 7-9 shown, a connecting rod 55 is rotatably connected to one side of the first slider 543 away from the arched hole 542. One end of the connecting rod 55 away from the first slider 543 is fixedly connected to a third rotating rod 551. The third rotating rod 551 penetrates and is rotatably connected to the outer protective shell 1. One end of the third rotating rod 551 away from the connecting rod 55 is fixedly connected to a first runner 552. A second runner 561 is also rotatably connected to the outer wall of the outer protective shell 1. A second transmission belt 56 is sleeved on the outer walls of the second runner 561 and the first runner 552. Second gears 562 are fixedly connected to one side of the two second runners 561. The two second gears 562 are meshed with each other. A rotating handle 57 is fixedly connected to one side of the second runner 561 away from the second gear 562. The rotating handle 57 penetrates and is rotatably connected to the outside of the interlayer 11.
[0042] It can be seen from this that when it is necessary to irrigate the seedlings cultivated in the seedbed, as Figures 1-3As shown, in the preparation stage, after the staff place the outer protective shell 1 on the top of the support frame 12, they then place the water storage layer 2 on the top of the support plate 4, and its position is restricted by the fixed columns 52 on both sides. At the same time, the position of the connecting pipe 531 is adjusted to fit the water outlet 21 by sliding the sliding plate 53. Then, after connecting the water tank 13 to the external water supply equipment, and then splicing the seedbed 3 to the outer wall of the water storage layer 2 through the strip-shaped grooves on both sides, the splicing of the plants in the seedbed 3 can be started;
[0043] As Figure 1 shown, under normal circumstances, water gushes out from the water outlet 21 and continuously flows towards the seedbed 3 in the middle of the water storage layer 2, and gradually penetrates into the seedbed 3 to irrigate the inside of the seedbed 3. Then, after the irrigation is completed, the water supply is turned off. At this time, the water level will continuously drop until the water in the water storage layer 2 runs out. During long-term use, the water flowing back and forth in the water storage layer 2 will carry out some soil from the seedbed 3. When the water flows back, sediment will flow back together. Then, when the nutrient solution is transported in next time, this soil will be mixed with the nutrient solution in the water tank 13 and pour into the seedbed 3. In this case, the water storage layer 2 and the seedbed 3 can be separated. Before the water recedes, ensure that the soil accumulates in the water storage layer 2 and then carry out cleaning and the transportation of the nutrient solution;
[0044] It should be noted that when the water recedes, the lower end of the overlapping position of the water storage layer 2 and the seedbed 3 is a concave part. When the soil sediments, it will preferentially fall into the concave part of the water storage layer 2. Then, when the water recedes, the soil deposited in the concave part will not be drained back into the water tank 13 by the water flow. At this time, after the nutrient solution is transported into the water storage layer 2, it will flow into the inside of the seedbed 3 first for absorption;
[0045] At this time, the staff pull the rotating handle 57. At this time, the rotating handle 57 will drive the second runner 561 to rotate, and at the same time drive the second gear 562 to rotate together. The simultaneous rotation of the two meshing second gears 562 on both sides will drive the two second runners 561 on both sides to rotate in the opposite direction. At this time, under the drive of the second transmission belt 56, the first runner 552, the third rotating rod 551 and the connecting rod 55 rotate together. At this time, the horizontal connecting rod 55 will drive the first slider 543 to rotate together during the rotation process. At this time, the first slider 543 will drive the rotating column 54 to rotate upward, and when the connecting rod 55 rotates to the vertical direction, the rotating column 54 rotates to the maximum angle. At this time, the second slider 544 will also rotate and, under the restriction of the convex column 5442 and the arched groove 31, drive the seedbed 3 to move up a certain distance. At this time, a certain height difference is formed between the seedbed 3 and the water storage layer 2. Then, the water and soil oozing out when the seedbed 3 moves up will directly fall into the concave part of the water storage layer 2 for sedimentation for a certain period of time. This ensures that when the seedbed 3 drops again during the next nutrient solution transportation, the nutrient solution will not be affected by the soil;
[0046] In addition, during the seedling raising process, different water levels of irrigation are given due to the growth characteristics of some plants. At this time, under the drive of the motor 51, the threaded rod 511 rotates. At this time, the threaded rod 511 drives the sliding column 521 to slide along the top of the fixed column 52. As Figure 8 shown, when the threaded rod 511 drives the sliding column 521 to slide to the right, the first slider 543 will gradually approach the position of the second rotating rod 522 of the rotating column 54. The closer the first slider 543 is to the second rotating rod 522, the larger the rotation angle of the rotating column 54 driven by the connecting rod 55 driving the first slider 543 to rotate. The larger the rotation angle of the rotating column 54, the greater the upward movement distance of the seedbed 3, and the lower the irrigation water level. By adjusting the height between the seedbed 3 and the water storage layer 2 to control the irrigation water level, on the one hand, it can cooperate with the sedimentation of the soil to ensure that the nutrient solution is not affected, and on the other hand, it can achieve the recycling of irrigation water;
[0047] It should be noted that by adjusting the up and down movement of the seedbed 3, in addition to the effect of forming sedimented soil for easy cleaning, when the water is drained at the water outlet 21 and the next irrigation is carried out, after inputting the nutrient solution, the irrigation water left after the previous water drainage in the water tank 13 can be mixed with the nutrient solution again for the next irrigation.
[0048] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art of this industry should understand that the present invention is not limited by the above embodiments. The above embodiments and the descriptions in the specification are only preferred examples of the present invention and are not used to limit the present invention.
