[0003] A search revealed Chinese patent publication number CN 116784127 A, which discloses a multifunctional intelligent fruit and vegetable seedling substrate post-processing machine. The machine comprises a substrate stirring mechanism, a quantitative water supply mechanism, a plug tray conveying mechanism, an auxiliary uniform discharging mechanism, a height-adjustable substrate scraping mechanism, and a control box. The quantitative water supply mechanism delivers a quantitative amount of water to the stirring box; the substrate stirring mechanism uniformly stirs substrates of different types and humidity requirements in the shortest possible time; the plug tray conveying mechanism drives the plug trays to move at a constant speed; the auxiliary uniform discharging mechanism allows the substrate to fall evenly into the plug trays; the height-adjustable substrate scraping mechanism scrapes away excess substrate on plug trays of different heights; and the control box controls the status of each electrical appliance, allowing all components to coordinate and orderly complete the substrate stirring, discharging, loading, and scraping processes. The present invention has a simple structure, is easy to use, and offers high substrate post-processing efficiency and strong universal applicability.

[0004] Regarding the above-mentioned related technologies, the inventors found the following defects: the existing seedling raising machine has uneven substrate processing during use, unstable sowing accuracy, inconsistent tightness of the hole tray substrate, and unstable sowing depth, resulting in uneven emergence time. Due to the looseness of the soil, the seeds after sowing are easily displaced after watering, resulting in the distance between the seeds being destroyed, affecting the normal growth of subsequent fruit and vegetable seedlings. Summary of the invention

[0005] The purpose of the present invention is to address the shortcomings of the existing technology and provide a multifunctional fruit and vegetable seedling raising machine and seedling raising method. The machine has a stable matrix structure, ensures that the seedlings take root and prevents collapse. By compacting the matrix, large pores inside the matrix can be eliminated, preventing the matrix from sinking after watering, resulting in seed displacement or seedling roots hanging in the air. The density of the compacted matrix is uniform, which can provide stable physical support for seed germination. It is particularly suitable for fruits and vegetables with delicate root systems and prevents seedlings from falling over.

[0006] The present invention achieves the above object through the following technical solutions. A multifunctional fruit and vegetable seedling raising machine and a seedling raising method include a base plate. At both ends of the upper surface of the base plate, two support legs are fixedly arranged, and at the top thereof, a middle force-bearing square frame is fixedly arranged. The inner wall of the middle force-bearing square frame is clamped and arranged with a substrate tank through a bolt rod. In the middle of the left end of the upper surface of the base plate, a vertical shaft is rotatably arranged. A clamping sleeve is sleeved on the top of the vertical shaft. A connecting block is fixedly arranged on the outer side of the clamping sleeve. At the right end of the upper surface of the connecting block, a top plate is fixedly arranged. At the middle position of the top of the top plate, a top arc plate is arranged. At the top position of the inner wall of the top arc plate, a second hydraulic rod is fixedly arranged. At the bottom of the second hydraulic rod, an arc-shaped support plate is fixedly arranged. At both ends of the bottom of the arc-shaped support plate, connecting vertical rods are fixedly arranged. At the bottom of the connecting vertical rods, a compaction plate is fixedly arranged. The compaction plate is vertically arranged with the substrate tank.

[0007] A cavity-dividing plate is slidably inserted into the upper surface of the compaction plate. A middle power plate is fixedly arranged on the top of the cavity-dividing plate. On one side of the top of the middle power plate, a lead screw is rotatably arranged through a support vertical plate. A threaded slider is threadedly sleeved on the outer side of the lead screw. At the top of the threaded slider, an inclined rod is rotatably arranged through a rotating rod. At the end of the inclined rod away from the threaded slider, a rotating frame is rotatably arranged through a rotating rod. At the top of the rotating frame, a connecting cross plate is fixedly arranged. On one side of the connecting cross plate, a first pressure plate is fixedly arranged. At the middle of one end of the upper surface of the first pressure plate, a first hydraulic rod is fixedly arranged. The end of the first hydraulic rod away from the first pressure plate is fixedly arranged on one side of the bottom of the top plate.

[0008] On one end of the upper surface of the base plate, a power square box is fixedly arranged. At the bottom of the inner wall of the power square box, a rotating power vertical shaft is rotatably arranged. The top of the rotating vertical shaft is fixedly connected to the bottom of the vertical shaft. A spur gear is fixedly sleeved on the middle of the rotating vertical shaft. The spur gear is meshed with a toothed bar through the teeth on the outer side. On one side of the toothed bar, a moving cross bar is fixedly arranged through a connecting plate. A moving electric telescopic rod is fixedly arranged on the moving cross bar. One end of the electric telescopic rod is fixedly arranged with a support vertical plate. The bottom of the support vertical plate is fixedly arranged on the bottom of the inner wall of the power square box.

[0009] Preferably, four identical grooves are arranged on the outer side of the top of the vertical shaft. The specifications of the grooves match the convex blocks on the inner wall of the clamping sleeve. The convex blocks on the inner wall of the clamping sleeve slide in the inner wall of the grooves to realize the tight clamping of the surface of the clamping sleeve and the vertical shaft.

[0010] Preferably, the thread directions at both ends of the outer surface of the lead screw are opposite. A handle is fixedly arranged at one end of the lead screw. A sliding plate is fixedly arranged at the bottom of the threaded slider threadedly sleeved on the surface of the lead screw. The two sides of the bottom of the sliding plate slide in the inner walls of the chutes at both ends of the upper surface of the middle power plate. The sliding plate at the bottom of the threaded slider slides in the inner walls of the chutes to prevent the threaded slider from generating coaxial rotation following the rotation of the lead screw.

[0011] Preferably, a hole-breaking cone is fixedly arranged at the bottom of the middle power plate. The length of the hole-breaking cone is greater than the height of the sub-hole plate. The diameter of the hole-breaking cone is the same as the diameter of the round hole on the surface of the compaction plate. When the middle power plate moves, it drives the hole-breaking cone to move towards the substrate, breaking holes in the substrate that has been cut, forming holes, which is convenient for sowing seeds.

[0012] Preferably, the sub-hole plate is composed of 5 transverse plates and 3 longitudinal plates. The transverse plates and longitudinal plates form a reticular hole groove. A hole-breaking cone is arranged in the middle of each hole groove. The height of the sub-hole plate is the same as the depth of the substrate groove. The reticular sub-hole plate is arranged to facilitate the treatment of the whole substrate into multiple block-shaped substrates, which is convenient for the later transplanting of fruit tree seedlings. The middle power plate is fixedly arranged at the top of the sub-hole plate.

[0013] Preferably, two groups of identical square telescopic sliding rods are fixedly arranged on both sides of the middle of the upper surface of the first pressure plate. The two groups of square telescopic sliding rods are located on both sides of the arc-shaped support plate. Circular telescopic sliding rods are fixedly arranged at both ends of the upper surface of the arc-shaped support plate. The top of the circular telescopic sliding rod is fixedly arranged at the bottom of the top plate. When the first pressure plate moves, the square telescopic sliding rods perform telescopic movement to ensure that the arc-shaped support plate can perform stable telescopic movement.

[0014] Preferably, the outer side of the compaction plate is processed with rounded corners. Multiple through tracks and through holes are arranged on the surface of the compaction plate. The width of the through track is the same as the thickness of the sub-hole plate. The width of the compaction plate is the same as the inner wall width of the substrate groove and is smaller than the width of the middle power plate. The through tracks and through holes facilitate the movement of the sub-hole plate and the hole-breaking cone. The width of the through track is the same as the thickness of the sub-hole plate.

[0015] A seedling raising method includes the following steps: S1. Extrude the substrate through the compaction plate slidably connected above the substrate groove to form seedling blocks; S2. Use the second hydraulic rod to move the sub-hole plate towards the compacted substrate through the middle power plate to semi-cut the formed seedling blocks; S3. Use the first hydraulic rod to drive the first pressure plate to move downward following the sub-hole plate and insert it into the square substrate after sub-hole division to form hole pits.

[0016] The beneficial effects of the present invention are as follows: For this multi-functional fruit and vegetable seedling raising machine and seedling raising method, by moving the compaction plate towards the substrate, the sub-hole plate cuts the compacted substrate, and the hole-breaking cone perforates the substrate. Appropriate compaction can reduce the air permeability of the substrate, slow down the water evaporation rate, and prevent seeds from drying to death due to water shortage. The thickness of the substrate layer is accurately controlled through the soil pressing device to ensure that the emergence time of seedlings in the same batch is consistent, which is convenient for large-scale management. The substrate is divided into independent hole holes to prevent the root systems of adjacent seedlings from entangling or competing for nutrients, which is convenient for unified management after transplantation and shortens the slow seedling stage.

[0019] 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. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] Please refer to Figures 1 - 8As shown in the figure, a multifunctional fruit and vegetable seedling raising machine includes a base plate 1. At both ends of the upper surface of the base plate 1, two support legs are fixedly arranged, and in the middle of the upper surface of the base plate 1, a middle force-bearing square frame 2 is fixedly arranged. The inner wall of the middle force-bearing square frame 2 is clamped and arranged with a substrate groove 3 through a bolt rod. In the middle of the left end of the upper surface of the base plate 1, a vertical shaft 13 is rotatably arranged. On the outer side of the top of the vertical shaft 13, four identical grooves are arranged. The specifications of the grooves match the bumps on the inner wall of the clamping sleeve 12. The bumps on the inner wall of the clamping sleeve 12 slide on the inner wall of the grooves, so as to realize the tight clamping of the clamping sleeve 12 on the surface of the vertical shaft 13.

[0021] On one side of the upper surface of the base plate 1, a tank body 26 is fixedly arranged. At the top of the tank body 26, a pressure pump 27 is fixedly arranged and communicated with it. At the top of the pressure pump 27, a water outlet pipe 36 is communicated. At the top of the water outlet pipe 36, a telescopic corrugated pipe 37 is communicated. One end of the telescopic corrugated pipe 37 far away from the water outlet pipe 36 is communicated with a main pipe 25. On one side of the top of the main pipe 25, a spray head is communicated. At both ends of the bottom of the main pipe 25, telescopic rods 28 are fixedly arranged. The bottom of the telescopic rods 28 is fixedly arranged on one side of the upper surface of the middle force-bearing square frame 2. When in use, the liquid or medicine for irrigation is added into the tank body 26, and the liquid is sprayed into the substrate groove through the pressure pump 27. At the same time, a telescopic pipe is set to realize the spraying liquid demand adapting to different heights. By adjusting the spraying height, it can be aimed at the plant heights at different growth stages (such as the seedling stage and the mature stage) of the crops, ensuring that the liquid medicine evenly covers the leaves, stems or the substrate around the roots, and avoiding "near-distance phytotoxicity" or "far-distance missed spraying" caused by fixed height.

[0022] Please refer to Figure 1 A clamping sleeve 12 is sleeved on the top of the vertical shaft 13. A connecting block 11 is fixedly arranged on the outer side of the clamping sleeve 12. On the right end of the upper surface of the connecting block 11, a top plate 7 is fixedly arranged. At the middle position of the top of the top plate 7, a top arc plate 17 is arranged. At the top position of the inner wall of the top arc plate 17, a second hydraulic rod 9 is fixedly arranged. At the bottom of the second hydraulic rod 9, an arc support plate 10 is fixedly arranged. At both ends of the bottom of the arc support plate 10, connecting vertical rods 16 are fixedly arranged. At the bottom of the connecting vertical rods 16, a compaction plate 4 is fixedly arranged. The outer side of the compaction plate 4 is processed with a rounded corner. After the rounded corner treatment, the pressure plate 4 is easier to slide inside the substrate groove 3. A plurality of through tracks and through holes are arranged on the surface of the compaction plate 4. The through tracks and through holes facilitate the movement of the sub-hole plate 22 and the hole-breaking cone 14. The width of the through track is the same as the thickness of the sub-hole plate 22. The width of the compaction plate 4 is the same as the inner wall width of the substrate groove 3 and less than the width of the middle power plate 15. The compaction plate 4 is vertically arranged with the substrate groove 3.

[0023] Please refer to Figure 2 and Figure 3, a sub-hole plate 22 is slidably inserted into the upper surface of the compaction plate 4. The sub-hole plate 22 is composed of 5 transverse plates and 3 longitudinal plates. The transverse plates and longitudinal plates form a net-shaped hole groove. A hole-breaking cone 14 is arranged in the middle of each hole groove. The height of the sub-hole plate 22 is the same as the depth of the substrate groove 3. The net-shaped sub-hole plate 22 is arranged to facilitate the treatment of the whole substrate into multiple block-shaped substrates, which is convenient for the later transplanting of fruit tree seedlings. A middle power plate 15 is fixedly arranged at the top of the sub-hole plate 22. A hole-breaking cone 14 is fixedly arranged at the bottom of the middle power plate 15. The length of the hole-breaking cone 14 is greater than the height of the sub-hole plate 22. The diameter of the hole-breaking cone 14 is the same as the diameter of the round hole on the surface of the compaction plate 4. When the middle power plate 15 moves, it drives the hole-breaking cone 14 to move towards the substrate direction to break holes in the cut substrate, forming holes, which is convenient for sowing seeds.

[0024] Please refer to Figure 2 , on one side of the top of the middle power plate 15, a lead screw 5 is rotatably arranged through a support vertical plate. The thread directions at both ends of the outer surface of the lead screw 5 are opposite. Opposite threads are arranged at both ends of the surface of the lead screw 5. During the rotation of the lead screw 5, the two thread sliders 21 at both ends can move relative to or towards each other at the same time. A handle is fixedly arranged at one end of the lead screw 5. A slide plate is fixedly arranged at the bottom of the thread slider 21 threadedly sleeved on the surface of the lead screw 5. The two sides of the bottom of the slide plate are slidably arranged on the inner walls of the chutes at both ends of the upper surface of the middle power plate 15. The slide plate at the bottom of the thread slider 21 slides on the inner wall of the chute to prevent the thread slider 21 from generating coaxial rotation following the rotation of the lead screw 5.

[0025] Please refer to Figure 1 , a thread slider 21 is threadedly sleeved on the outer side of the lead screw 5. One end of the inclined rod 19 is rotatably arranged on the top of the thread slider 21 through a rotating rod. The other end of the inclined rod 19 away from the thread slider 21 is rotatably arranged on a rotating frame 20 through a rotating rod. A connecting cross plate 23 is fixedly arranged at the top of the rotating frame 20. A first pressure plate 18 is fixedly arranged on one side of the connecting cross plate 23. Two groups of identical square telescopic slide rods 6 are fixedly arranged on both sides of the middle of the upper surface of the first pressure plate 18. The two groups of square telescopic slide rods 6 are located on both sides of the arc-shaped support plate 10. Circular telescopic slide rods 24 are fixedly arranged at both ends of the upper surface of the arc-shaped support plate 10. The top of the circular telescopic slide rods 24 is fixedly arranged at the bottom of the top plate 7. When the first pressure plate 18 moves, the square telescopic slide rods 6 perform telescopic movement to ensure that the arc-shaped support plate 10 can perform stable telescopic movement. A first hydraulic rod 8 is fixedly arranged in the middle of one end of the upper surface of the first pressure plate 18. The end of the first hydraulic rod 8 away from the first pressure plate 18 is fixedly arranged on one side of the bottom of the top plate 7.

[0026] One end of the upper surface of the base plate 1 is fixedly provided with a power square box 35. At the bottom of the inner wall of the power square box 35, a rotating power vertical shaft 34 is rotatably arranged. The top of the rotating vertical shaft 34 is fixedly connected to the bottom of the vertical shaft 13. A straight gear 33 is fixedly sleeved in the middle of the rotating vertical shaft 34. The straight gear 33 is meshed with a toothed bar 29 through the teeth on the outside. One side of the toothed bar 29 is fixedly provided with a moving cross bar 30 through a connecting plate. A moving fixing electric telescopic rod 31 is arranged on the moving cross bar 30. One end of the electric telescopic rod 31 is fixedly provided with a supporting vertical plate 32. The bottom of the supporting vertical plate 32 is fixedly arranged at the bottom of the inner wall of the power square box 35. When the electric telescopic rod 31 expands and contracts, while driving the toothed bar 29 to move, it can drive the straight gear 33 to rotate. Under the action of the straight gear 33, the vertical shaft 13 can rotate smoothly, so as to realize the rotation effect of changing the upper top plate 7.

[0027] A seedling raising method includes the following steps: S1. The substrate is extruded by the compaction plate 4 slidably connected above the substrate tank 3 to form seedling blocks. The extruded substrate can be made into regular shapes. Each unit of substrate corresponds to a fixed sowing position, avoiding the problem of uneven seed distribution during manual sowing.

[0028] S2. The second hydraulic rod 9 is used to move the cell plate 22 towards the compacted substrate through the middle power plate 15 to semi-cut the formed seedling blocks. The cut substrate blocks are separated from each other. The seedling roots are limited to grow within a single unit, avoiding the cross-winding of the roots of different plants. When transplanting, the complete substrate block can be directly taken out, reducing the root injury rate and shortening the slow seedling stage.

[0029] S3. The first hydraulic rod 8 is used to drive the first pressure plate 18 to move downward following the cell plate 22 and insert it into the square substrate after cell division to form a hole, ensuring one seed per hole, improving the seedling raising quality, with a compact structure, reasonable layout of each component, small floor area, and suitable for fruit and vegetable seedling raising places of different scales.

[0030] The implementation principle of a multifunctional fruit and vegetable seedling raising machine and a seedling raising method of the present invention is as follows: First, put the seedling raising substrate soil for sowing into the interior of the substrate tank 3. After spreading an appropriate amount of substrate, start the electric telescopic rod 31 so that the toothed bar 29 can move smoothly. When the toothed bar 29 moves, it drives the spur gear 33 to rotate. The spur gear 33 drives the vertical shaft 13 to rotate through the rotating vertical shaft 34 in the middle. By rotating the vertical shaft 13, the compaction plate 4 is positioned above the substrate tank 3. Start the second hydraulic rod 9 as the power, and drive the compaction plate 4 to move into the interior of the substrate tank 3 through the connecting vertical rod 16. Squeeze the soil inside the substrate tank 3 through the compaction plate 4, so that the large pores in the internal soil are reduced. At the same time, adjust the tightness to balance the air permeability and water retention. After the extrusion is completed, the compaction plate 4 is above the substrate. At this time, start the first hydraulic rod 8 to drive the first compaction plate 18 and the middle power plate 15 below to move towards the substrate. Cut the substrate through the sub-hole plate 22 below, so that the substrate forms separate blocks. The cut substrate blocks are separated from each other, and the seedling roots are confined to grow within a single unit, avoiding the cross entanglement of the roots of different plants. At the same time, after the hole-breaking cone 14 contacts the substrate, holes are formed, which is convenient for subsequent sowing of seeds. This kind of seedling raising is convenient for subsequent transplantation. Adjust the distance between the bottoms of the two inclined rods 19 by rotating the screw rod 5, so as to adjust the distance between the first compaction plate 18 and the middle power plate 15 below, and facilitate controlling the depth of the holes broken in the substrate by the hole-breaking cone 14, and can meet the requirements of different seeds for the depth of the hole pits.
