Technical Field

[0001] The present invention relates to the technical field of vegetable seedling raising, and particularly relates to a vegetable seedling raising device with adjustable water temperature. Background Art

[0002] Vegetable seedling raising refers to the process of cultivating seedlings in a specific environment before vegetable planting. Vegetable seeds are sown in a suitable substrate, and appropriate temperature, humidity, light, nutrients and other conditions are provided to promote the seeds to germinate and grow into strong seedlings. Seedling raising can improve the survival rate of vegetables, facilitate centralized management, and lay a good foundation for subsequent planting.

[0003] During the process of vegetable seedling raising, water temperature plays a crucial role in the growth and development of seedlings. However, in the prior art, existing seedling raising devices often have difficulty in controlling the water temperature, resulting in poor seedling raising effects and affecting the quality and survival rate of vegetable seedlings.

The nutrient soil is made by the stirring device, and then the lead screw is rotated by a motor to make the soil adding device operate to add the nutrient soil stirred by the stirring device into the seedling raising box. At the same time, the water required for seedling raising is sprayed into the seedling raising box through the spraying device. The leaked liquid in the seedling raising box can be collected by the liquid collecting box;

[0005] The spray device includes a water storage tank. Both sides of the water storage tank are fixedly connected with water inlet pipes. At the center of the inner cavity of the water storage tank, a hollow heat insulation plate is fixedly connected. The inner wall of the water storage tank is fixedly connected with an annular waterproof plate. The outer side of the annular waterproof plate is fixedly connected with a heating wire. The bottom of the water storage tank is fixedly connected with a temperature regulating component. The bottom of the temperature regulating component is fixedly connected with a water outlet pipe. The bottom of the water outlet pipe is fixedly connected with a nozzle. By providing the hollow heat insulation plate, the interior of the water storage tank is divided into two chambers. The user can add water to the two chambers of the water storage tank through the two water inlet pipes respectively. Subsequently, the chamber on the side of the water storage tank where the annular waterproof plate is installed is heated by the heating wire. Under the heat insulation effect of the hollow heat insulation plate, the water storage tank can simultaneously keep warm and store the nursery water at two temperatures;

[0006] The temperature regulating component includes a mixing cylinder. The outer side of the mixing cylinder is rotationally connected with a turntable. The outer wall of the turntable is fixedly connected with a pneumatic push rod through a mounting frame. The output end of the pneumatic push rod is fixedly connected with a diversion frame. The side wall of the diversion frame is fixedly connected with a sliding ring. The outer wall of the sliding ring is slidably connected with a flow blocking plate. The inner wall of the mixing cylinder is fixedly connected with a temperature sensor. By the telescopic movement of the pneumatic push rod, the position of the diversion frame in the mixing cylinder is changed, so that the sliding ring moves together with the diversion frame. The sliding ring can block the two water outlets at the bottom of the water storage tank. When the sliding ring moves, it can change the cross-sectional area of the water flow outlets of the two chambers of the water storage tank, so that the water output of the two chambers of the water storage tank is different.

[0007] Preferably, the outer wall of the water storage tank is fixedly connected with the outer side of the soil filling device. The outer wall of the water outlet pipe is fixedly connected with the outer wall of the water storage tank through a fixing frame. The bottom of the water storage tank is fixedly connected with the top of the mixing cylinder. The inner wall of the mixing cylinder is slidably connected with the outer wall of the flow blocking plate. The outer wall of the sliding ring is slidably connected with the inner wall of the mixing cylinder. By rotating the turntable, the pneumatic push rod drives the sliding ring to rotate in the mixing cylinder through the diversion frame. At this time, the flow blocking plate deflects upward under the limiting action of the sliding ring and blocks the opening at the top of the mixing cylinder. At this time, the water in the water storage tank can be prevented from entering the mixing cylinder.

[0008] Preferably, the stirring device includes a support frame. The inner side of the support frame is fixedly connected with a mixing hopper. The outer side of the mixing hopper is fixedly connected with a stirring motor. The output end of the stirring motor is fixedly connected with a stirring frame. The bottom of the mixing hopper is fixedly connected with a blanking component. Both sides of the stirring frame are rotationally connected with the inner wall of the mixing hopper. The bottom of the support frame is fixedly connected with the top of the nursery rack. The stirring motor can drive the stirring frame to rotate in the mixing hopper, so that the nutrient soil and nutrient agent are evenly mixed in the mixing hopper. The mixed nutrient soil can be discharged outward through the blanking component.

[0009] Preferably, the blanking assembly includes a blanking pipe. On both sides of the outer wall of the blanking pipe, there are side guard plates slidably connected. Inside the side guard plates, there are sliding rods rotatably connected. On the outer wall of the sliding rods, there are baffle plates rotatably connected. Inside the blanking pipe, there is a limit sliding sleeve slidably connected. Inside the limit sliding sleeve, there is a top block fixedly connected. The top rod in the soil filling device contacts the side guard plate and pushes the side guard plate to slide along the outside of the blanking pipe. At this time, the side guard plate can push the baffle plate to slide inside the blanking pipe through the sliding rod. During this process, a gap is generated between the bottom of the baffle plate and the opening at the bottom of the blanking pipe, enabling the nutrient soil to flow out smoothly.

[0010] Preferably, the top of the blanking pipe is fixedly connected to the bottom of the mixing hopper. The outer wall of the sliding rod is slidably connected to the inner wall of the blanking pipe through a chute. The inner wall of the blanking pipe is slidably connected to the top of the baffle plate. The top of the baffle plate contacts the bottom of the limit sliding sleeve. The top of the baffle plate can push the limit sliding sleeve upward, causing the limit sliding sleeve to drive the top block to move upward. During the upward movement of the top block, it can loosen the nutrient soil accumulated at the bottom of the mixing hopper, preventing the nutrient soil from accumulating at the bottom of the mixing hopper.

[0011] Preferably, the soil filling device includes a sliding frame. Inside the sliding frame, there is a fixed plate fixedly connected. At the bottom of the fixed plate, there is a rotating frame rotatably connected. On both sides of the rotating frame, there are torsion springs fixedly connected. On the outer wall of the rotating frame, there is a material receiving plate rotatably connected. At the bottom of the material receiving plate, there is a scraping rod fixedly connected. At the bottom of the rotating frame, there is a support rod rotatably connected. Inside the sliding frame, there is a scraping assembly fixedly connected. On the outside of the fixed plate, there is a top rod fixedly connected. By setting the support rod to support the material receiving plate, when the material receiving plate deflects downward, the support rod can rotate as the material receiving plate deflects, reducing the wear of the support rod by the material receiving plate. At the same time, the support rod is fixed by the rotating frame, and the rotating frame is connected to the fixed plate through the torsion spring, enabling the support rod to drive the material receiving plate to reset when the shoveling rod disengages from the material receiving plate.

[0012] Preferably, the inner wall at the bottom of the sliding frame is threadedly connected to the outer wall of the lead screw. The outside of the sliding frame is slidably connected to the side wall of the seedling raising frame. The top of the outer wall of the sliding frame is fixedly connected to the outer wall of the water storage tank. The end of the torsion spring away from the rotating frame is fixedly connected to the outer wall of the fixed plate. The outer wall of the support rod is in rolling connection with the bottom of the material receiving plate. By setting the scraping rod, when the material receiving plate deflects downward, the scraping rod can scrape the excess nutrient soil in the seedling box into the collection groove.

[0013] Preferably, the scraping component includes a telescopic cylinder. The output end of the telescopic cylinder is fixedly connected to a connecting plate. The bottom of the connecting plate is fixedly connected to a shoveling rod. The bottom of the shoveling rod is slidably connected to the outer wall of the material receiving plate. The outside of the telescopic cylinder is fixedly connected to the inner wall of the sliding frame. When the shoveling rod slides along the surface of the material receiving plate, it can shovel off the nutrient soil attached to the surface of the material receiving plate, preventing the nutrient soil from adhering to the surface of the material receiving plate.

[0014] Preferably, the outside of the connecting plate is slidably connected to the outer wall of the fixing plate. A sliding plate is slidably connected to the outer wall of the fixing plate. An elastic scraping piece is fixedly connected to the inner wall of the sliding plate. The outer wall of the elastic scraping piece is slidably connected to the outer wall of the shoveling rod. The elastic scraping piece slides along the surface of the shoveling rod and can scrape off the nutrient soil attached to the surface of the shoveling rod during the sliding process.

[0015] Preferably, an elastic plate is fixedly connected to the outer wall of the fixing plate. The top of the elastic plate is fixedly connected to the inside of the sliding frame. The outer wall of the elastic plate is slidably connected to the side wall of the connecting plate. By setting the elastic plate, when the connecting plate moves upward, the elastic plate can knock on the connecting plate under the action of its own elastic force, causing the shoveling rod installed at the bottom of the connecting plate to vibrate.

[0016] The beneficial effects of the present invention are as follows:

[0017] 1. By setting the spraying device in the present invention, the inside of the water storage tank is divided into two chambers by the hollow heat insulation plate. The user can add water to the two chambers of the water storage tank through two water inlet pipes respectively, and then heat the chamber on the side of the water storage tank where the annular waterproof plate is installed through the heating wire. Under the heat insulation effect of the hollow heat insulation plate, the water storage tank can simultaneously keep warm and store the nursery water at two temperatures.

[0018] 2. By setting the temperature regulating component in the present invention, the positions of the diversion frame and the sliding ring in the mixing cylinder are changed by the telescopic movement of the pneumatic push rod. The sliding ring can block the two water outlets at the bottom of the water storage tank. When the sliding ring moves, it can change the cross-sectional area of the water flow outlets of the two chambers of the water storage tank, so that the water output of the two chambers of the water storage tank is different. Then the water flows in the two chambers are mixed in the mixing cylinder, and then the temperature of the water in the mixing cylinder is detected by the temperature sensor, so that the temperature of the water flow when it is sprayed can be regulated.

[0019] 3. By setting the temperature regulating component in the present invention, after the spraying is completed, by rotating the turntable, the pneumatic push rod drives the sliding ring to rotate in the mixing cylinder through the diversion frame. At this time, the baffle plate deflects upward under the limiting action of the sliding ring and blocks the opening at the top of the mixing cylinder. At this time, the water in the water storage tank can be prevented from entering the mixing cylinder, resulting in the mixing of the water in the two chambers of the water storage tank in the mixing cylinder.

[0020] 4. By providing a blanking component in the present invention, during the process of the soil filling device approaching the mixing device, the ejector rod in the soil filling device contacts the side guard plate and pushes the side guard plate to slide along the outer side of the blanking pipe. At this time, the side guard plate can push the baffle plate to slide in the blanking pipe through the sliding rod. During this process, a gap is generated between the bottom of the baffle plate and the opening at the bottom of the blanking pipe, enabling the nutrient soil to flow out smoothly. Thus, the automatic filling process of the nutrient soil can be completed.

[0021] 5. By providing a blanking component in the present invention, during the process of the baffle plate sliding in the blanking pipe, the top of the baffle plate pushes the limit sliding sleeve upward, causing the limit sliding sleeve to drive the top block to move upward. During the upward movement of the top block, the nutrient soil accumulated at the bottom of the mixing hopper can be loosened, preventing the nutrient soil from accumulating at the bottom of the mixing hopper and enabling the nutrient soil to flow smoothly into the bearing plate through the blanking pipe.

[0022] 6. By providing a soil filling device in the present invention, the telescopic cylinder in the scraping component drives the shoveling rod to move downward through the connecting plate, causing the shoveling rod to squeeze the bearing plate downward. At this time, the bearing plate can deflect downward, and the nutrient soil can fall into the seedling raising box under the action of gravity. During this process, the shoveling rod slides along the surface of the bearing plate and can also shovel off the nutrient soil attached to the surface of the bearing plate, preventing the nutrient soil from adhering to the surface of the bearing plate.

[0023] 7. By providing a soil filling device in the present invention, during the downward deflection of the bearing plate, the support rod can rotate along with the deflection of the bearing plate, reducing the wear of the bearing plate on the support rod. The rotating frame is connected to the fixed plate through a torsion spring, enabling the support rod to drive the bearing plate to reset when the shoveling rod disengages from the bearing plate. At the same time, by providing a scraping rod, when the bearing plate deflects downward, the scraping rod can scrape the excess nutrient soil in the seedling raising box into the collection tank.

[0024] 8. By providing a scraping component in the present invention, when the telescopic cylinder drives the shoveling rod to move upward through the connecting plate, the sliding plate slides along the surface of the fixed plate along with the movement of the shoveling rod, increasing the movable range of the elastic scraping piece. At the same time, the elastic scraping piece slides along the surface of the shoveling rod and can scrape off the nutrient soil attached to the surface of the shoveling rod during the sliding process.

[0025] 9. By providing a scraping component in the present invention, through the provision of an elastic plate, when the connecting plate moves upward, the elastic plate can knock on the connecting plate under its own elastic force, causing the shoveling rod installed at the bottom of the connecting plate to vibrate. During the vibration process of the shoveling rod, it can knock on the elastic scraping piece, thereby shaking off the residual nutrient soil attached to the surfaces of the shoveling rod and the elastic scraping piece.

[0038] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present invention are given for purposes of illustration and description, and are not exhaustive or limit the present invention to the disclosed forms. Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and design various embodiments with various modifications suitable for specific purposes.

[0039] Embodiment: Please refer to Figure 1 - Figure 11 , the present invention provides a technical solution: a vegetable seedling raising device with adjustable water temperature, comprising:

[0040] A seedling raising frame 1, which is used for supporting the overall components of the device. A lead screw 5 is rotatably connected to the inner wall of the seedling raising frame 1, and a liquid collecting box 2 is fixedly connected to the inner wall of the seedling raising frame 1; A seedling raising box 3, which is used for holding vegetable seeds. The side wall of the seedling raising box 3 is snap-connected to the inner wall of the seedling raising frame 1, and the seedling raising box 3 is located directly above the liquid collecting box 2; A stirring device 4, which is used for stirring the nutrient soil. The bottom of the stirring device 4 is fixedly connected to the top of the seedling raising frame 1, and a collecting groove 8 is formed in the wall of the seedling raising frame 1; A soil adding device 6, which is used for adding nutrient soil into the seedling raising box 3. The bottom of the soil adding device 6 is slidably connected to the side wall of the seedling raising frame 1. The soil adding device 6 is located on the side of the stirring device 4 close to the seedling raising box 3, and the bottom of the soil adding device 6 is threadedly connected to the outer wall of the lead screw 5; A spraying device 7, which is used for supplementing water into the seedling raising box 3. The side of the spraying device 7 close to the stirring device 4 is fixedly connected to the outside of the soil adding device 6. The spraying device 7 is located on the top of the seedling raising box 3. Place vegetable seeds in the seedling raising box 3, then snap the seedling raising box 3 onto the top of the seedling raising frame 1. Subsequently, make the nutrient soil through the stirring device 4, and then drive the lead screw 5 to rotate by a motor to make the soil adding device 6 operate to add the nutrient soil stirred by the stirring device 4 into the seedling raising box 3. At the same time, spray the water required for seedling raising into the seedling raising box 3 through the spraying device 7. The leaked liquid in the seedling raising box 3 can be collected by the liquid collecting box 2, and the excess nutrient soil in the seedling raising frame 1 can be pushed into the collecting groove 8 by the soil adding device 6 to complete the collection;

[0041] The spraying device 7 includes a water storage tank 71. Two sides of the water storage tank 71 are fixedly connected with water inlet pipes 72. A hollow heat insulation plate 73 is fixedly connected at the center of the inner cavity of the water storage tank 71. An annular waterproof plate 74 is fixedly connected to the inner wall of the water storage tank 71. A heating wire 75 is fixedly connected to the outer side of the annular waterproof plate 74. A temperature regulating component 76 is fixedly connected to the bottom of the water storage tank 71. A water outlet pipe 77 is fixedly connected to the bottom of the temperature regulating component 76. A spray head 78 is fixedly connected to the bottom of the water outlet pipe 77. When the spraying device 7 is in operation, the inner part of the water storage tank 71 is divided into two chambers by setting the hollow heat insulation plate 73. The user can add water to the two chambers of the water storage tank 71 through the two water inlet pipes 72 respectively. Subsequently, the chamber on the side of the water storage tank 71 where the annular waterproof plate 74 is installed is heated by the heating wire 75. Under the heat insulation effect of the hollow heat insulation plate 73, the water storage tank 71 can simultaneously keep warm and store the nursery water at two temperatures. Subsequently, the water flow rate of the two chambers when water flows out is regulated by the temperature regulating component 76, so that the temperature of the water flow when it sprays out can be changed, making the temperature of the water flow when it sprays out match the suitable temperature of the environment of the vegetable seeds. Finally, the water flow can be sprayed outwards through the spray head 78 installed at the bottom of the water outlet pipe 77;

[0042] The temperature control component 76 includes a mixing cylinder 761. A turntable 765 is rotatably connected to the outside of the mixing cylinder 761. An air cylinder 766 is fixedly connected to the outer wall of the turntable 765 through a mounting bracket. The output end of the air cylinder 766 is fixedly connected to a diversion bracket 764. A sliding ring 763 is fixedly connected to the side wall of the diversion bracket 764. A flow blocking plate 762 is slidably connected to the outer wall of the sliding ring 763. A temperature sensor 767 is fixedly connected to the inner wall of the mixing cylinder 761. The outer wall of the water storage tank 71 is fixedly connected to the outside of the soil filling device 6. The outer wall of the water outlet pipe 77 is fixedly connected to the outer wall of the water storage tank 71 through a fixing bracket. The bottom of the water storage tank 71 is fixedly connected to the top of the mixing cylinder 761. The inner wall of the mixing cylinder 761 is slidably connected to the outer wall of the flow blocking plate 762. The outer wall of the sliding ring 763 is slidably connected to the inner wall of the mixing cylinder 761. During regulation, the telescopic movement of the air cylinder 766 is used to change the position of the diversion bracket 764 in the mixing cylinder 761, so that the sliding ring 763 moves together with the diversion bracket 764. The sliding ring 763 can block the two water outlets at the bottom of the water storage tank 71. When the sliding ring 763 moves, it can change the cross-sectional area of the water flow outlets of the two chambers of the water storage tank 71, so that the water output of the two chambers of the water storage tank 71 is different. Then the water flows in the two chambers are mixed in the mixing cylinder 761, and then the temperature sensor 767 is used to detect the water temperature in the mixing cylinder 761, so that the temperature of the water flow when spraying can be regulated. After the spraying is completed, by rotating the turntable 765, the air cylinder 766 drives the sliding ring 763 to rotate in the mixing cylinder 761 through the diversion bracket 764. At this time, the flow blocking plate 762 deflects upward under the restriction of the sliding ring 763 and blocks the opening at the top of the mixing cylinder 761, so that the water in the water storage tank 71 can be prevented from entering the mixing cylinder 761, resulting in the mixing of the water in the two chambers of the water storage tank 71 in the mixing cylinder 761.

[0043] The stirring device 4 includes a support frame 41. A mixing hopper 42 is fixedly connected to the inside of the support frame 41.

A feeding component 45 is fixedly connected to the bottom of the mixing hopper 42. Both sides of the stirring frame 44 are rotatably connected to the inner wall of the mixing hopper 42. The bottom of the support frame 41 is fixedly connected to the top of the seedling raising frame 1. When stirring the nutrient soil, pour the nutrient agent of the nutrient soil into the mixing hopper 42 installed inside the support frame 41. At this time, the stirring motor 43 can drive the stirring frame 44 to rotate in the mixing hopper 42 to mix the nutrient soil and the nutrient agent evenly in the mixing hopper 42. The mixed nutrient soil can be discharged outward through the feeding component 45.

[0044] The blanking assembly 45 includes a blanking pipe 451. On both sides of the outer wall of the blanking pipe 451, side guard plates 452 are slidably connected. Inside the side guard plates 452, sliding rods 453 are rotatably connected. On the outer wall of the sliding rods 453, baffle plates 454 are rotatably connected. Inside the blanking pipe 451, a limiting sliding sleeve 455 is slidably connected. Inside the limiting sliding sleeve 455, a top block 456 is fixedly connected. The top of the blanking pipe 451 is fixedly connected to the bottom of the mixing hopper 42. The outer wall of the sliding rod 453 is slidably connected to the inner wall of the blanking pipe 451 through a chute. The inner wall of the blanking pipe 451 is slidably connected to the top of the baffle plate 454. The top of the baffle plate 454 is in contact with the bottom of the limiting sliding sleeve 455. During the process of the soil filling device 6 approaching the mixing device 4, the ejector rod 68 in the soil filling device 6 contacts the side guard plate 452 and pushes the side guard plate 452 to slide along the outside of the blanking pipe 451. At this time, the side guard plate 452 can push the baffle plate 454 to slide inside the blanking pipe 451 through the sliding rod 453. During this process, a gap is generated between the bottom of the baffle plate 454 and the opening at the bottom of the blanking pipe 451, enabling the nutrient soil to flow out smoothly. Thus, the automatic filling process of the nutrient soil can be completed. At the same time, the top of the baffle plate 454 pushes the limiting sliding sleeve 455 upward, causing the limiting sliding sleeve 455 to drive the top block 456 to move upward. During the upward movement of the top block 456, the nutrient soil accumulated at the bottom of the mixing hopper 42 can be loosened, preventing the nutrient soil from accumulating at the bottom of the mixing hopper 42 and enabling the nutrient soil to smoothly flow into the material receiving plate 64 through the blanking pipe 451.

[0045] The soil filling device 6 includes a sliding frame 61. A fixed plate 62 is fixed inside the sliding frame 61. A rotating frame 63 is rotatably connected to the bottom of the fixed plate 62. Torsion springs 66 are fixedly connected to both sides of the rotating frame 63. An earth-receiving plate 64 is rotatably connected to the outer wall of the rotating frame 63. A scraping rod 65 is fixedly connected to the bottom of the earth-receiving plate 64. A support rod 67 is rotatably connected to the bottom of the rotating frame 63. A scraping component 60 is fixedly connected to the inner side of the sliding frame 61. A push rod 68 is fixedly connected to the outer side of the fixed plate 62. The inner wall of the bottom of the sliding frame 61 is threadedly connected to the outer wall of the lead screw 5. The outer side of the sliding frame 61 is slidably connected to the side wall of the seedling-raising frame 1. The top of the outer wall of the sliding frame 61 is fixedly connected to the outer wall of the water storage tank 71. One end of the torsion spring 66 away from the rotating frame 63 is fixedly connected to the outer wall of the fixed plate 62. The outer wall of the support rod 67 is in rolling connection with the bottom of the earth-receiving plate 64. When the soil filling device 6 is in use, the nutrient soil is filled by setting the earth-receiving plate 64. Subsequently, the motor drives the lead screw 5 to rotate, so as to change the position of the sliding frame 61 on the seedling-raising frame 1, making the earth-receiving plate 64 move to the upper part of the seedling box 3. Among them, the support rod 67 is set to support the earth-receiving plate 64. During the process of the earth-receiving plate 64 deflecting downward, the support rod 67 can rotate along with the deflection of the earth-receiving plate 64, reducing the wear of the earth-receiving plate 64 on the support rod 67. At the same time, the rotating frame 63 is used to fix the support rod 67, and the rotating frame 63 is connected to the fixed plate 62 through the torsion spring 66, so that when the shoveling rod 623 is separated from the earth-receiving plate 64, the support rod 67 can drive the earth-receiving plate 64 to reset. At the same time, by setting the scraping rod 65, when the earth-receiving plate 64 deflects downward, the scraping rod 65 can scrape the excess nutrient soil in the seedling box 3 into the collection groove 8.

[0046] The scraping component 60 includes a telescopic air cylinder 621. The output end of the telescopic air cylinder 621 is fixedly connected to a connecting plate 622. The bottom of the connecting plate 622 is fixedly connected to a shoveling rod 623. The bottom of the shoveling rod 623 is slidably connected to the outer wall of the material receiving plate 64. The outside of the telescopic air cylinder 621 is fixedly connected to the inner wall of the sliding frame 61. The outside of the connecting plate 622 is slidably connected to the outer wall of the fixing plate 62. A sliding plate 624 is slidably connected to the outer wall of the fixing plate 62. An elastic scraping piece 626 is fixedly connected to the inner wall of the sliding plate 624. The outer wall of the elastic scraping piece 626 is slidably connected to the outer wall of the shoveling rod 623. An elastic plate 625 is fixedly connected to the outer wall of the fixing plate 62. The top of the elastic plate 625 is fixedly connected to the inside of the sliding frame 61. The outer wall of the elastic plate 625 is slidably connected to the side wall of the connecting plate 622. When it is necessary to pour the nutrient soil filled in the material receiving plate 64 into the seedling raising box 3, the telescopic air cylinder 621 in the scraping component 60 drives the shoveling rod 623 to move downward through the connecting plate 622, so that the shoveling rod 623 presses the material receiving plate 64 downward. At this time, the material receiving plate 64 can deflect downward, and the nutrient soil can fall into the seedling raising box 3 under the action of gravity. During this process, the shoveling rod 623 slides along the surface of the material receiving plate 64, and can also shovel off the nutrient soil attached to the surface of the material receiving plate 64 to prevent the nutrient soil from adhering to the surface of the material receiving plate 64. When the telescopic air cylinder 621 drives the shoveling rod 623 to move upward through the connecting plate 622, the sliding plate 624 slides along the surface of the fixing plate 62 as the shoveling rod 623 moves, increasing the movable range of the elastic scraping piece 626. At the same time, the elastic scraping piece 626 slides along the surface of the shoveling rod 623, and can scrape off the nutrient soil attached to the surface of the shoveling rod 623 during the sliding process; by setting the elastic plate 625, when the connecting plate 622 moves upward, the elastic plate 625 can knock on the connecting plate 622 under its own elastic force, so that the shoveling rod 623 installed at the bottom of the connecting plate 622 generates vibration. The shoveling rod 623 can knock on the elastic scraping piece 626 during the vibration process, and thus the residual nutrient soil attached to the surfaces of the shoveling rod 623 and the elastic scraping piece 626 can be shaken off.

[0047] Working principle:

[0048] During use, vegetable seeds are placed in the seedling raising box 3, and then the seedling raising box 3 is clamped to the top of the seedling raising frame 1. Subsequently, the nutrient soil is made by the stirring device 4, and then the motor drives the lead screw 5 to rotate, so that the soil adding device 6 operates to add the nutrient soil stirred by the stirring device 4 into the seedling raising box 3. At the same time, the required water for seedling raising is sprayed into the seedling raising box 3 through the spraying device 7. The liquid leakage in the seedling raising box 3 can be collected by the liquid collecting box 2, and the excess nutrient soil in the seedling raising frame 1 can be pushed into the collecting groove 8 by the soil adding device 6 to complete the collection;

[0049] When the spraying device 7 is in operation, the interior of the water storage tank 71 is divided into two chambers by setting the hollow heat insulation plate 73. The user can add water to the two chambers of the water storage tank 71 through the two water inlet pipes 72 respectively. Subsequently, the chamber on the side of the water storage tank 71 where the annular waterproof plate 74 is installed is heated by the heating wire 75. Under the heat insulation effect of the hollow heat insulation plate 73, the water storage tank 71 can simultaneously keep the nursery water at two temperatures warm and stored. Subsequently, the temperature regulating component 76 regulates the water flow rate when the water in the two chambers flows out, thereby changing the temperature of the water flow when it is sprayed, so that the temperature of the water flow when it is sprayed matches the suitable temperature of the environment of the vegetable seeds. The water flow can finally be sprayed outwards through the nozzle 78 installed at the bottom of the water outlet pipe 77;

[0050] During regulation, the telescopic movement of the pneumatic push rod 766 is used to change the position of the diversion frame 764 in the mixing cylinder 761, so that the sliding ring 763 moves together with the diversion frame 764. The sliding ring 763 can block the two water outlets at the bottom of the water storage tank 71. When the sliding ring 763 moves, it can change the cross-sectional area of the water flow outlets of the two chambers of the water storage tank 71, so that the water output of the two chambers of the water storage tank 71 is different. Subsequently, the water flows in the two chambers are mixed in the mixing cylinder 761, and then the temperature sensor 767 detects the water temperature in the mixing cylinder 761, thereby regulating the temperature of the water flow when it is sprayed;

[0051] After the spraying is completed, by rotating the turntable 765, the pneumatic push rod 766 drives the sliding ring 763 to rotate in the mixing cylinder 761 through the diversion frame 764. At this time, the baffle plate 762 deflects upwards under the limiting action of the sliding ring 763 and blocks the opening at the top of the mixing cylinder 761, preventing the water in the water storage tank 71 from entering the mixing cylinder 761 and causing the water in the two chambers of the water storage tank 71 to be mixed in the mixing cylinder 761;

[0052] When stirring the nutrient soil, pour the nutrient agent of the nutrient soil into the mixing hopper 42 installed inside the support frame 41. At this time, the stirring motor 43 can drive the stirring frame 44 to rotate in the mixing hopper 42 to mix the nutrient soil and the nutrient agent evenly in the mixing hopper 42. The mixed nutrient soil can be discharged outwards through the feeding component 45;

[0053] During the process of the soil filling device 6 approaching the mixing device 4, the ejector rod 68 inside the soil filling device 6 contacts the side guard plate 452 and pushes the side guard plate 452 to slide along the outer side of the blanking pipe 451. At this time, the side guard plate 452 can push the baffle plate 454 to slide inside the blanking pipe 451 through the sliding rod 453. During this process, a gap is generated between the bottom of the baffle plate 454 and the opening at the bottom of the blanking pipe 451, enabling the nutrient soil to flow out smoothly. Thus, the process of automatic filling of the nutrient soil can be completed; meanwhile, the top of the baffle plate 454 pushes the limit sliding sleeve 455 upward, causing the limit sliding sleeve 455 to drive the top block 456 to move upward. During the upward movement of the top block 456, the nutrient soil accumulated at the bottom of the mixing hopper 42 can be loosened, preventing the nutrient soil from accumulating at the bottom of the mixing hopper 42 and enabling the nutrient soil to smoothly flow into the receiving plate 64 through the blanking pipe 451;

[0054] When the soil filling device 6 is in use, the receiving plate 64 is used to fill the nutrient soil. Subsequently, the motor drives the lead screw 5 to rotate, which can change the position of the sliding frame 61 on the seedling raising frame 1, enabling the receiving plate 64 to move above the seedling raising box 3; when it is necessary to pour the nutrient soil filled in the receiving plate 64 into the seedling raising box 3, the telescopic cylinder 621 in the scraping component 60 drives the shoveling rod 623 to move downward through the connecting plate 622, causing the shoveling rod 623 to squeeze the receiving plate 64 downward. At this time, the receiving plate 64 can deflect downward, and the nutrient soil can fall into the seedling raising box 3 under the action of gravity. During this process, the shoveling rod 623 slides along the surface of the receiving plate 64 and can also shovel off the nutrient soil adhering to the surface of the receiving plate 64, preventing the nutrient soil from adhering to the surface of the receiving plate 64;

[0055] Among them, the receiving plate 64 is supported by setting the support rod 67. During the process of the receiving plate 64 deflecting downward, the support rod 67 can rotate along with the deflection of the receiving plate 64, reducing the wear of the receiving plate 64 on the support rod 67. At the same time, the support rod 67 is fixed by the rotating frame 63, and the rotating frame 63 is connected to the fixed plate 62 through the torsion spring 66, enabling the support rod 67 to drive the receiving plate 64 to reset when the shoveling rod 623 disengages from the receiving plate 64. At the same time, by setting the scraping rod 65, when the receiving plate 64 deflects downward, the scraping rod 65 can scrape the excess nutrient soil in the seedling raising box 3 into the collection groove 8;

[0056] When the telescopic cylinder 621 drives the shoveling rod 623 to move upward through the connecting plate 622, the sliding plate 624 slides along the surface of the fixed plate 62 with the movement of the shoveling rod 623, increasing the movable range of the elastic scraping piece 626. At the same time, the elastic scraping piece 626 slides along the surface of the shoveling rod 623 and can scrape off the nutrient soil adhering to the surface of the shoveling rod 623 during the sliding process;

[0057] By setting the elastic plate 625, when the connecting plate 622 moves upward, the elastic plate 625 can strike the connecting plate 622 under the action of its own elastic force, causing the material shoveling rod 623 installed at the bottom of the connecting plate 622 to vibrate. During the vibration process of the material shoveling rod 623, it can strike the elastic scraping blade 626, thereby shaking off the residual nutrient soil adhering to the surfaces of the material shoveling rod 623 and the elastic scraping blade 626.
