[0038] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts belong to the scope of protection of the present invention.

[0039] Referring to Figure 1 、 Figure 3 and Figure 4 , an embodiment provided by the present invention: a seedling-raising device for lettuce, including a housing 1. Both the middle and bottom of the inner wall of the housing 1 are fixedly connected with seedling-raising shells 3. The bottom of the seedling-raising shell 3 is communicated with a filter plate 4. Through the filter plate 4, excess irrigation water can be filtered out, thus facilitating the collection of water. The bottom wall of the bottom filter plate 4 is communicated with a water filtration device 5, so that the finally filtered water can be uniformly filtered and cleaned. The left side of the water filtration device 5 is communicated with a suction pipe 6. The top of the suction pipe 6 is communicated with a pressure pump 7. The top of the pressure pump 7 is communicated with a delivery pipe 8. The top of the delivery pipe 8 is communicated with an addition bucket 9, so that the pressure pump 7 can extract and deliver the filtered water. The delivered water flow will enter the interior of the addition bucket 9. The left side of the addition bucket 9 is communicated with an injection valve 10. The inner wall of the addition bucket 9 is rotatably connected with a mixing wheel 11. The delivered water flow can impact the mixing wheel 11. Thus, the nutrient solution added into the addition bucket 9 through the injection valve 10 can be mixed and stirred by the mixing wheel 11, thereby improving the effect of spraying and irrigating water. The top wall of the addition bucket 9 is communicated with a connecting pipe 12. The right side of the connecting pipe 12 is communicated with a porous nozzle 13. The rear side of the pressure pump 7 is fixedly connected to the front bottom of the housing 1. The right side of the addition bucket 9 is fixedly connected to the right side of the housing 1. The right side of the housing 1 is rotatably connected with a sealing door 15. Through the sealing door 15, the device can be opened and closed. A displacement mechanism 2 is arranged at the top rear of the inner wall of the housing 1;

[0040] Specifically, the sprayed and irrigated water moves downward through the top seedling-raising shell 3 and the bottom seedling-raising shell 3 to provide necessary irrigation for the plants. At the same time, the excess water is filtered out through the filter plate 4 and enters the water filtration device 5. Through a series of filtration steps, the filtered clear water is pumped to the delivery pipe 8 under the action of the pressure pump 7, and then enters the addition bucket 9. Inside the addition bucket 9, the water flow impacts the mixing wheel 11, causing it to rotate. The nutrient solution is injected into the addition bucket through the injection valve 10. The rotation of the mixing wheel 11 promotes the efficient mixing of the nutrient solution and the water flow. The uniformly mixed irrigation liquid is then transmitted to the porous nozzle 13 through the connecting pipe 12 to achieve spraying and irrigation, which not only improves the utilization efficiency of water resources, reduces water waste, but also reduces the labor cost of operators.

[0041] Referring to Figure 1 、Figure 3 and Figure 5 The displacement mechanism 2 includes a fixed housing 201. The rear side of the fixed housing 201 is fixedly connected to the top of the inner wall of the outer housing 1. A sliding groove 202 is formed on the front side of the fixed housing 201 to guide and support the displacement of the sliding housing 204. A rack seat 203 is fixedly connected to the inner bottom wall of the fixed housing 201. A sliding housing 204 is arranged on the front side of the fixed housing 201. The outer wall of the sliding housing 204 is slidably connected to the sliding groove 202. A servo motor 205 is fixedly connected to the rear side of the sliding housing 204. When the servo motor 205 is started, the gear 206 can be driven. The output end of the servo motor 205 is fixedly connected to a gear 206. The gear 206 is meshed with the rack seat 203. Further, the gear 206 can rotate on the top of the rack seat 203, thereby driving the sliding housing 204 to displace. A connecting plate 207 is fixedly connected to the front side of the sliding housing 204. The top wall of the porous nozzle 13 is fixedly installed at the bottom of the connecting plate 207, so that the porous nozzle 13 can be fixedly installed, thereby increasing the spraying and irrigation range;

[0042] Specifically, after the servo motor 205 is started, as a power source, it drives the gear 206 to start rotating. The gear 206 is located on the top of the rack seat 203, and its rotational motion is converted into a horizontal rotational displacement along the rack seat, causing the sliding housing 204 to perform a linear displacement in the axial direction along the trajectory of the sliding groove 202. As the sliding housing 204 displaces, the porous nozzle 13 also moves accordingly within the spraying area, so that the spraying coverage range of the porous nozzle 13 is no longer limited to a fixed position, but can be dynamically adjusted with the displacement of the sliding housing, thereby effectively expanding the spraying range, improving the uniformity and efficiency of irrigation, reducing the interference of human factors, and further enhancing the accuracy and stability of irrigation.

[0043] Referring to Figure 1 、 Figure 4 and Figure 5 The displacement mechanism 2 further includes a limiting plate 208. The bottom wall of the limiting plate 208 is fixedly connected to the top wall of the sliding housing 204. A limiting groove 209 is formed on the top wall of the fixed housing 201. The rear side of the limiting plate 208 is slidably connected to the limiting groove 209; A rubber ring 21 is fixedly installed at the top end of the outer wall of the conveying pipe 8. The outer wall of the rubber ring 21 is fixedly connected to the bottom wall of the adding bucket 9; A control switch 18 is fixedly connected to the top of the front side of the outer housing 1. The control switch 18 is electrically connected to the water filtering device 5, the pressure pump 7, and the servo motor 205 respectively;

[0044] Specifically, by slidingly connecting the rear side of the limit plate 208 with the limit groove 209, the stability of the sliding shell 204 during displacement is improved. Through the rubber ring 21, the top connection of the conveying pipe 8 can be protected, thereby reducing the wear at the top of the conveying pipe 8. Through the control switch 18 electrically connected to the water filtration device 5, the pressure pump 7, and the servo motor 205 respectively, the control switch 18 can complete the opening and closing of the device.

[0045] Refer to Figure 1 and Figure 4 On the front side of the sealing door 15, a handle 16 is fixedly connected. In the middle of the handle 16, a rubber sleeve 17 is fixedly connected; in the middle of the injection valve 10, a sealing ring 14 is fixedly connected. The outer shape of the sealing ring 14 is designed in a cylindrical shape; on the front and rear sides of the outer shell 1, connecting seats 19 are fixedly connected. On the top wall of the connecting seat 19, an installation groove 20 is opened;

[0046] Specifically, the handle 16 facilitates the opening and closing of the sealing door 15. The rubber sleeve 17 improves the anti-slip effect of the handle 16. Through the sealing ring 14, the sealing effect of the connection between the injection valve 10 and the addition barrel 9 is improved. Through the connecting seat 19 and the installation groove 20, it is convenient to install and fix the device.

[0047] Working principle: When starting to use, the excess water for irrigation can be filtered out through the filter plate 4. Then, the irrigation water at the top enters the top seedling-raising shell 3 and the bottom seedling-raising shell 3 in sequence. Finally, the filtered water enters the interior of the water filtration device 5. The water filtered by the water filtration device 5 during operation can be pumped by the pressure pump 7. Then, the water flow is transported through the conveying pipe 8 into the interior of the addition barrel 9, so that the transported water flow impacts and drives the mixing wheel 11. Through the injection valve 10, nutrient solution can be added into the addition barrel 9. By the rotation of the mixing wheel 11, the nutrient solution can be better mixed with the transported water flow. Thus, through the transportation of the connecting pipe 12, and then sprayed and irrigated through the porous nozzle 13, the utilization rate of water resources is improved, avoiding the waste of water and the increase in the labor cost of the operator. And by starting the servo motor 205, the gear 206 rotates. Thus, the gear 206 rotates and displaces on the top of the rack seat 203. Then, the rotational displacement of the gear 206 can drive the sliding shell 204 to perform an axial displacement inside the sliding groove 202, so that the porous nozzle 13 fixedly installed through the connecting plate 207 can be driven. Then, the porous nozzle 13 can move together with the sliding shell 204 during spraying and irrigation, thus expanding the moving range of the porous nozzle 13 and improving the seedling-raising effect, increasing the practicality of the device.

[0048] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or perform equivalent replacements on some of the technical features.
