[0037] Reference Figure 1-Figure 12 The present invention provides a crop seedling raising device, comprising a No. 1 raising plate 1, a No. 2 raising plate 2 and a bottom plate 3, wherein the No. 1 raising plate 1, the No. 2 raising plate 2 and the bottom plate 3 are arranged in parallel with each other, and the No. 1 raising plate 1, the No. 2 raising plate 2 and the bottom plate 3 are arranged in an upper, middle and lower manner, and the No. 2 raising plate 2 and the bottom plate 3 are arranged at intervals, and the spacing between the No. 2 raising plate 2 and the bottom plate 3 can be adjusted, and a fence is fixedly connected to the top surface of the No. 2 raising plate 2 around, and the No. 1 raising plate 1 can be directly placed on the fence, and the bottom of the No. 1 raising plate 1 is also fixedly connected to the bottom block, and the bottom block can directly abut against the top surface of the No. 2 raising plate 2, and a plurality of vertically arranged seed sending rods 4 are fixedly installed on the top surface of the bottom plate 3, and the No. 2 raising plate 2 is provided with through holes, and the number of the through holes is the same as the number of the seed sending rods 4 and is arranged one by one, and the top of the seed sending rod 4 is located at the through hole In the actual use process, a soft rubber block is installed at the top of the seed delivery rod 4, and a groove is opened at the top of the soft rubber block. The diameter of the seed delivery rod 4 is slightly smaller than the inner diameter of the perforation. At the same time, under normal circumstances, the top of the seed delivery rod 4 is located in the perforation. In actual use, the seeds are poured on the No. 2 cultivation plate 2, and the No. 2 cultivation plate 2 is shaken so that there is a seed in each perforation, and the seed is located in the groove of the soft rubber block at the top of the seed delivery rod 4. In actual conditions, the diameter of the seed delivery rod 4 is smaller than the diameter of the seed (normal seeds need to be full and the sizes of the seeds are relatively consistent). A lifting structure is provided between the No. 2 cultivation plate 2 and the bottom plate 3. The lifting structure is used to drive the No. 2 cultivation plate 2 and the bottom plate 3 to move away from each other. The No. 2 cultivation plate 2 is supported by the lifting structure to ensure that the seeds are located in the perforations and reduce the occurrence of seeds detaching from the perforations.

[0038] When the seeds are buried in the nutrient soil, a seedling cone 5 is fixedly installed on the No. 1 cultivation board 1. The number of the seedling cones 5 is the same as the number of perforations and is arranged one by one. A seed inlet is opened at the bottom of the seedling cone 5. The top of the seed delivery rod 4 can pass through the seed inlet and enter the seedling cone 5. First, pour the nutrient soil on the No. 1 cultivation board 1, then scrape and flatten the excess nutrient soil on the No. 1 cultivation board 1, and then place the No. 1 cultivation board 1 on the fence. The staff presses the No. 1 cultivation board 1. , the No. 2 cultivation plate 2 is pressed down by the No. 1 cultivation plate 1 and moves downward synchronously, while the position of the seed delivery rod 4 remains unchanged, and the seed delivery rod 4 and the No. 2 cultivation plate 2 move relative to each other, so that the seeds are sent from the seed inlet into the nutrient soil in the seedling cone 5 (entering from the bottom of the seedling cone 5), and when the No. 1 cultivation plate 1 is pressed to the bottom, after the seed delivery rod 4 sends the seeds into the seedling cone 5, since the diameter of the seed delivery rod 4 is smaller than the diameter of the seeds, after the No. 1 cultivation plate 1 is loosened, the jacking structure The second cultivation plate 2 and the first cultivation plate 1 are driven to rise, so that the seed delivery rod 4 is drawn out from the seedling cone 5. When the seed delivery rod 4 is drawn out, since the diameter of the seed is larger than that of the seed delivery rod 4, the seed will be stuck by the nutrient soil in the seedling cone 5, and the seed will not fall down, so that the seed will remain in the nutrient soil in the seedling cone 5 to complete the seed sowing. At the same time, when the jacking structure drives the second cultivation plate 2 and the first cultivation plate 1 to rise, the first cultivation plate 1 will vibrate, so that the nutrient soil in the seedling cone 5 will vibrate and fall to the position below the seed, thereby wrapping the seed. At the same time, the perforations at the bottom can ensure the ventilation effect of the seed during the cultivation process and ensure the conditions for the germination of the seed (the traditional sowing effect requires the use of a pricking roller to roll on the nutrient soil on the first cultivation plate 1, which will compact the nutrient soil in the seedling cone 5, and cover the seeds with a layer of floating soil after sowing them into the seedling cone 5, which affects the ventilation effect of the nutrient soil, and requires secondary covering soil).

[0039] like Figure 6 , Figure 7 , Figure 8 and Fig. 9 As shown in the figure, a cross silicone valve 6 is installed in the seed inlet, and the top of the seed delivery rod 4 can pass through the opening on the cross silicone valve 6 and enter the seedling cone 5; the middle cross opening of the cross silicone valve 6 has a circular opening at the intersection, and the diameter of the circular opening is smaller than the diameter of the seed, ensuring that the seed itself cannot pass through the circular opening when not affected by external force, and the diameter of the circular opening is larger than the diameter of the seed delivery rod 4. In actual operation, due to the setting of the seed inlet, the nutrient soil in the seedling cone 5 will fall and be lost. The design of the cross silicone valve 6 can ensure the ventilation effect in the seedling cone 5, reduce the loss of nutrient soil, and also reduce the situation of seeds falling.

[0040] like Figure 1 , Figure 3 , Figure 4 and Fig.12 As shown in the figure, the lifting structure includes a limiting column 7, a limiting tube 8 and a lifting spring 9; the bottom end of the limiting column 7 is fixedly connected to the top surface of the bottom plate 3, the limiting tube 8 is fixedly installed on the No. 2 cultivation plate 2, and the bottom end of the limiting tube 8 is provided with a lifting hole that slides with the limiting column 7. The lifting spring 9 is located in the lifting hole, and the two ends of the lifting spring 9 are respectively connected to the top of the limiting column 7 and the top inner wall of the lifting hole. The top of the limiting column 7 is retracted and extended in the limiting tube 8, and the limiting column 7 is driven by the lifting spring 9 to extend out of the limiting tube 8, thereby ensuring the spacing between the bottom plate 3 and the No. 2 cultivation plate 2. When sowing seeds, ensure that the top end of the seed delivery rod 4 is located in the middle position of the inner part of the perforation, thereby ensuring the positioning of the seeds, so as to facilitate the seeds to be accurately delivered into the seedling cone 5.

[0041] like Figure 3 , Figure 4 , Figure 6 , Figure 7 and Fig.10 As shown in, in actual conditions, after the seed delivery rod 4 delivers the seeds into the seedling cone 5, after the seed delivery rod 4 is pulled out of the seedling cone 5, certain cavities may appear at the bottom of the seeds, which may cause excessive water loss during watering. Therefore, it is necessary to fill the cavities at the bottom of the seeds. An impact structure is installed on the No. 2 cultivation plate 2. When the distance between the No. 2 cultivation plate 2 and the bottom plate 3 is reduced, the impact structure can impact on the cross silicone valve 6. In actual operation, when the No. 2 cultivation plate 2 descends, when the seed delivery rod 4 delivers the seeds into the nutrient soil of the seedling cone 5, As the seed delivering rod 4 rises in the seedling cone 5, the impact structure rises synchronously with the seed delivering rod 4, and the impact structure impacts the cross silicone valve 6, so that the cross silicone valve 6 is squeezed and deformed, so that the nutrient soil in the seedling cone 5 is squeezed. When the seed delivering rod 4 is pulled out of the seedling cone 5, the cross silicone valve 6 is squeezed. After the impact structure is separated from the cross silicone valve 6, the cross silicone valve 6 is reset and deformed, and the nutrient soil in the seedling cone 5 is affected by gravity. The nutrient soil falls down and fills the hole generated after the seed delivering rod 4 is pulled out, thereby reducing the loss of water and soil.

[0042] like Figure 3 , Figure 4 , Figure 6 , Figure 7 and Fig.10As shown in, the impact structure includes an auxiliary cylinder 10, an auxiliary spring 11 and a pushing block 12; the number of auxiliary cylinders 10 is the same as the number of perforations and is arranged one by one, the auxiliary cylinder 10 is slidably installed in the perforation, and the auxiliary cylinder 10 is sleeved on the outer periphery of the seed delivery rod 4. In the process of seed delivery, the seed delivery rod 4 first rises to send the seeds into the seedling cone 5, and then the pushing block 12 contacts the auxiliary cylinder 10 and pushes the pushing block 12 to move upward. The outer periphery of the auxiliary cylinder 10 is circumferentially connected with a boss, and the inner wall of the perforation is provided with a limiting slide groove that slidably cooperates with the boss. The auxiliary spring 11 is located in the limiting slide groove, and the two ends of the auxiliary spring 11 are respectively connected to the boss. The top of the auxiliary cylinder 10 is connected with the top inner wall of the limiting slide groove, and the pushing block 12 is fixedly mounted on the outer periphery of the seedling cone 5. The pushing block 12 is used to drive the auxiliary cylinder 10 to slide in the perforation. When the seed delivery rod 4 delivers seeds into the seedling cone 5, the pushing block 12 and the seed delivery rod 4 move synchronously. When the No. 2 cultivation plate 2 descends, the pushing block 12 and the No. 2 cultivation plate 2 produce a relative upward movement, and the pushing block 12 pushes the auxiliary cylinder 10 to slide out of the perforation. The top of the auxiliary cylinder 10 rises and abuts against the cross silicone valve 6, thereby deforming the cross silicone valve 6. When resetting, the auxiliary spring 11 pushes the auxiliary cylinder 10 to slide and reset in the perforation.

[0043] At present, when transplanting the seedlings on the seedling tray, the staff usually grabs the seedling plant and pulls out the root and stem of the plant and the nutrient soil in the hole of the seedling tray simultaneously. Since the seedling is relatively tender at this time, it is necessary to control the force when pulling it out. The seedling cannot be pulled out with less force, and excessive force may cause the seedling to be injured or even broken, affecting the survival of the seedling. Therefore, the following design is provided.

[0044] like Figure 1 , Figure 6 , Figure 7 and Figure 8As shown in, it also includes a seedling panel 13; a seedling opening 14 is opened on the seedling panel 13, and the number of the seedling openings 14 is the same as the number of the seedling cones 5 and is arranged one by one, and the top of the seedling cone 5 is slidably installed in the seedling opening 14, the seedling panel 13 is arranged in parallel with the No. 1 cultivation board 1, and the seedling panel 13 is located directly above the No. 1 cultivation board 1, and an elastic supporting structure and an adjusting structure are arranged between the No. 1 cultivation board 1 and the seedling panel 13, the elastic supporting structure is used to drive the seedling panel 13 and the No. 1 cultivation board 1 to move away from each other, and the adjusting structure is used to drive the seedling panel 13 and the No. 1 cultivation board 1 to move towards each other. During normal seedling cultivation, the support structure lifts up the seedling panel 13 so that the No. 1 cultivation board 1 A certain distance is maintained between the seedling raising panel 13 and the seedling raising cone 5, so that the top opening of the seedling raising cone 5 is located in the seedling raising opening 14. When the nutrient soil is filled, the nutrient soil will also fill the seedling raising opening 14. When the distance between the seedling raising panel 13 and the No. 1 cultivation plate 1 is reduced by adjusting the structure, the seedling raising cone 5 rises in the seedling raising opening 14 and pushes the nutrient soil block in the seedling raising opening 14 out of the seedling raising opening 14. When transplanting, the staff can grab a section of the nutrient soil pushed out of the seedling raising opening 14 by hand, and pull the rhizomes and nutrient soil of the seedlings out of the seedling raising cone 5 (because the rhizomes of the seedlings are evenly distributed in the nutrient soil, the nutrient soil is grasped tightly, and when the seedlings are pulled out, the damage to the seedlings is reduced), thereby ensuring the survival rate of the seedlings.

[0045] like Figure 1 , Figure 2 and Fig.11 As shown in the figure, the elastic support structure includes a support tube 15, a support column 16 and a support spring 17; the support column 16 is driven to rise in the support tube 15 by the rebound action of the support spring 17, ensuring the distance between the No. 1 cultivation plate 1 and the seedling panel 13, so that the top of the seedling cone 5 is located in the seedling opening 14, the support tube 15 is fixedly installed on the top surface of the No. 1 cultivation plate 1, and the top of the support tube 15 is provided with a telescopic hole that slides with the support column 16. The top of the support column 16 is fixedly connected to the bottom surface of the seedling panel 13, the support spring 17 is located in the telescopic hole, and the two ends of the support spring 17 are respectively connected to the bottom end of the support column 16 and the bottom inner wall of the telescopic hole.

[0046] like Figure 1 , Figure 2 and Figure 5As shown in, the adjustment structure includes a handle No. 18, a handle No. 2 19, a trapezoidal block No. 1 20 and a trapezoidal block No. 2 21; the handle No. 18 is slidably mounted on the bottom surface of the seedling raising panel 13, the handle No. 2 19 is slidably mounted on the top surface of the No. 1 cultivation panel 1, the trapezoidal block No. 1 20 is fixedly connected to the bottom surface of the handle No. 1 18, the trapezoidal block No. 2 21 is fixedly connected to the top of the handle No. 2 19, the bottom inclined surface of the trapezoidal block No. 1 20 is slidably connected to the top inclined surface of the trapezoidal block No. 2 21, and in actual operation, the handle No. 1 18 and the handle No. 2 19 are at the same height, as shown in the figure. Figure 5 As shown in the figure, it is convenient for the staff to operate and apply force. The cross-sectional views of trapezoidal block No. 1 20 and trapezoidal block No. 2 21 are both right-angled trapezoids. Under normal circumstances, trapezoidal block No. 1 20 and trapezoidal block No. 2 21 can be assembled into a hexahedron. When the inclined surfaces on trapezoidal block No. 1 20 and trapezoidal block No. 2 21 slide and cooperate with each other, the distance between the upper and lower surfaces on trapezoidal block No. 1 20 and trapezoidal block No. 2 21 changes, thereby driving the distance between the No. 1 cultivation plate 1 and the seedling panel 13, thereby controlling the position of the top of the seedling cone 5 in the seedling opening 14, which is convenient for the staff to operate and also convenient for the work to carry the entire seedling device.

[0047] The steps for raising crop seedlings are as follows:

[0048] Step 1: Pour the nutrient soil on the top surface of the seedling raising panel 13, the nutrient soil enters the seedling raising cone 5 on the first cultivation plate 1 through the seedling raising opening 14, and then scrape the nutrient soil on the seedling raising panel 13 flat;

[0049] Step 2: Pour the seeds onto the top surface of the No. 2 cultivation plate 2, and shake the No. 2 cultivation plate 2 so that there is a seed in each perforation;

[0050] Step 3: Place the No. 1 cultivation plate 1 on top of the No. 2 cultivation plate 2, and press the seedling panel 13 downward. During this process, the staff holds the No. 1 handle 18 and the No. 2 handle 19 by hand to reduce the pressure on the nutrient soil on the seedling cone 5 and compact the nutrient soil, thereby ensuring the air permeability of the nutrient soil during seedling cultivation, so that the No. 1 cultivation plate 1 and the No. 2 cultivation plate 2 are synchronously lowered, and the seed delivery rod 4 is raised in the perforation. The top end of the seed delivery rod 4 pushes the seeds in the perforation through the cross silicone valve 6 and enters the nutrient soil in the seedling cone 5, and at the same time, the push block 12 pushes the auxiliary cylinder 10 against the cross silicone valve 6;

[0051] Step 4: Loosen the seedling raising panel 13, the second cultivation plate 2 rises on the bottom plate 3, and the top end of the seed delivery rod 4 is drawn out from the seedling raising cone 5 and retracted into the perforation;

[0052] Step 5: Seedling management: After the seedlings are grown, the seeds need to be fertilized, watered, and protected from pests and diseases;

[0053] Step 6: Grasp the No. 1 handle 18 and the No. 2 handle 19 respectively and pull them away from each other to reduce the spacing between the seedling panel 13 and the No. 1 cultivation plate 1, and the seedling cone 5 pushes the nutrient soil and the seedling in the pit out of the seedling opening 14, and grasps the nutrient soil protruding outside the seedling opening 14 to take out the roots of the seedlings and the nutrient soil at the roots for transplanting. During transplanting, the No. 1 cultivation plate 1 is supported by a support frame, and two vertically arranged slides are slidably installed on the support frame. The two slides are respectively inserted in the No. 1 handle 18 and the No. 2 handle 19, and the two slides move away from each other to pull the No. 1 handle 18 and the No. 2 handle 19, so that the tops of the two seedling cones 5 rise in the seedling opening 14, which is convenient for the staff to take out the seedlings. At the same time, the entire seedling raising device can be positioned to reduce the possibility of the seedling raising device being overturned.
