Description

Technical Field

[0001] This invention belongs to the field of agricultural machinery technology, specifically a vegetable seedling planting device. Background Technology

[0002] Transplanting vegetable seedlings is the process of transferring well-cultivated seedlings from the nursery to the field or greenhouse. This is crucial for the growth quality and yield of vegetables, effectively extending their effective growing period. By raising seedlings in a protected environment in advance, avoiding early spring frosts, and ensuring that crops grow in a suitable environment, they can be transplanted to the field after the temperature rises, thus gaining a longer growing time, improving seed utilization, and reducing planting costs.

[0003] In the existing technology, large-scale transplanting of vegetable seedlings is mostly done by transplanting machines. The transplanting machine mainly consists of a frame, a furrow opener, a planting mechanism, a hollow wheel for covering soil, and auxiliary devices.

[0021] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0022] like Figures 1 to 4As shown in the embodiment of the present invention, a vegetable seedling planting device is towed by a tractor and includes a support plate 1; a pair of symmetrically arranged mounting plates 2 are fixedly connected to the top surface of the support plate 1; a gap is left between the mounting plate 2 and its bottom support plate 1; a feeding groove 3 is formed on the surface of the support plate 1 at the corresponding position of the mounting plate 2; a feeding plate 4 is arranged between the mounting plate 2 and the support plate 1; a plurality of evenly arranged placement grooves 5 are formed on the bottom surface of the feeding plate 4; a pair of symmetrically arranged spring pieces 6 are installed at the bottom of the placement grooves 5; a through groove 7 is formed on the top surface of the feeding plate 4 at the corresponding position of the placement grooves 5; the mounting plate Multiple evenly arranged pressure plates 8 are slidably connected to the top surface of plate 2; each pressure plate 8 is arranged in a one-to-one correspondence with the through groove 7 at its bottom, and the through groove 7 is smaller than the placement groove 5; chain groups 9 are installed at the bottom of the support plate 1 at the corresponding positions of the feeding groove 3; multiple evenly arranged receiving plates 10 are fixedly connected to the surface of the chain groups 9; a pair of guide plates 11 are fixedly connected to the bottom surface of the support plate 1 at the corresponding positions of the two chain groups 9; a shovel plate 12 is fixedly connected to one side of the bottom of the guide plate 11; a soil covering wheel 13 is installed on the bottom surface of the support plate 1 on the side of the guide plate 11 away from the insert plate; the chain groups 9, the feeding plate 4, and the pressure plates 8 are all driven by a drive assembly through a motor;During operation, to ensure that the feeding rate of vegetable seedlings matches the seedling placement rate, thereby reducing the occurrence of missed or excessive seedlings, this embodiment of the invention can be used. Firstly, before transplanting the vegetable seedlings, the user needs to place each vegetable seedling individually into its respective placement slot 5 on the surface of the feeding plate 4. The spring clip 6 prevents the vegetable seedlings from detaching from the slot 5. Furthermore, because the vegetable seedlings are elongated and the through-slot 7 is smaller than the placement slot 5, the vegetable seedlings will not detach from the through-slot 7 either. Thus, the vegetable seedlings are stored in the placement slots 5 on the surface of the feeding plate 4. Subsequently, the user then connects this embodiment of the invention to a tractor... Next, the tractor acts as the power source for forward movement, propelling the embodiment of the invention forward along the field. During this process, the drive assembly moves the feeding plate 4 to the mounting plate 2. Subsequently, the pressure plate 8 presses down and passes through the mounting plate 2 and the through groove 7 into the placement groove 5 of the feeding plate 4, thereby squeezing the vegetable seedlings and spring pieces 6 in the placement groove 5. This causes the spring pieces 6 to deflect, allowing the vegetable seedlings to fall between the pairs of spring pieces 6. The vegetable seedlings then pass through the discharge groove 3 and fall onto the chain assembly 9, where they are finally caught by the receiving plate 10 on the surface of the chain assembly 9. Each vegetable seedling falls into only one receiving plate 10. Subsequently, the chain assembly 9 drives... The receiving plate 10 on its surface moves, feeding the vegetable seedlings one by one to the guide plate 24. During the movement of the present invention, the shovel plate 12 on one side of the guide plate 24 will dig trenches in the field for transplanting, and the vegetable seedlings in the guide will fall evenly into the transplanting trenches one by one. Then, after the soil covering wheel 13 passes through the transplanting trench, it will push the soil on both sides of the trench to the middle of the transplanting trench, thereby covering the vegetable seedlings and completing the transplanting operation. When the vegetable seedlings in one row of placement slots 5 of the feeding plate 4 are used up, the drive component will drive the feeding plate 4 to move towards the mounting plate 2, and move the next row of placement slots 5 of the feeding plate 4. The chain assembly 9 moves to directly beneath the mounting plate 2. At this point, a portion of the vegetable seedlings contained in the receiving plate 10 on the chain assembly 9 will move to the feeding trough 3. Then, the pressing plate 8 presses back into the placement trough 5, pressing the vegetable seedlings in the placement trough 5 back into the receiving plate 10. This completes the feeding of the vegetable seedlings to the receiving plate 10 again. This process is repeated, allowing the vegetable seedlings to be transplanted evenly one by one into the field. Through the coordination of the pressing plate 8, the feeding mechanism, and the drive assembly, manual feeding is no longer required, thus avoiding missed or excessive seedlings due to the unstable feeding rate of manual feeding. This ensures both transplanting quality and efficiency.

[0023] like Figures 1 to 3As shown, the drive assembly includes a drive rod 14; the drive rod 14 is rotatably connected to the bottom surface of the support plate 1 and is driven by a servo motor; the drive rod 14 is connected to the chain assembly 9 via a belt; a pair of intermittent gears 15 are rotatably connected to the top surface of the support plate 1, and the intermittent gears 15 are connected to the drive rod 14 via a gear set; after the drive rod 14 drives the chain assembly 9 to guide all the vegetable seedlings at the receiving plate 10 into the pair of guide plates 24, the intermittent gears 15 rotate one revolution, thereby driving the next row of placement slots 5 of the loading plate 4 to move to the unloading slot 3; the two intermittent gears 15 are respectively meshed with the loading plate 4 closest to their side; the top surface of the support plate 1 is between the two mounting plates 2. A rotating turntable 16 is rotatably connected to the drive rod 14 via a gear set 2; a connecting plate 17 is fixedly connected to the top surface of the pressure plate 8; a spring 18 is fixedly connected between the connecting plate 17 and the mounting plate 2; a pressure rod 19 is fixedly connected to the side of the turntable 16 near the connecting plate 17; after the drive rod 14 drives the chain set 9 to guide all the vegetable seedlings at the receiving plate 10 between the paired guide plates 24, the turntable 16 rotates exactly one revolution, thereby causing the pressure plate 8 on the surface of the turntable 16 to press the connecting plate 17 once; during operation, when the chain set 9 needs to work, the servo motor will drive the drive rod 14 to rotate, and the drive rod 14 will drive the chains on both sides to rotate synchronously and in the same direction via a belt, while the drive rod 14... While driving the chain assembly 9, the drive rod 14 also drives the intermittent gear 15 to rotate through the gear assembly. After the vegetable seedlings in the row of placement slots 5 of the feeding plate 4 are unloaded, the intermittent gear 15 rotates one revolution and meshes with the side of the feeding plate 4. This moves the next row of placement slots 5 on the surface of the feeding plate 4 to the mounting plate 2, preparing for the unloading of the next batch of vegetable seedlings. At the same time, the drive rod 14 also drives the turntable 16 to rotate. After the next row of placement slots containing vegetable seedlings 5 ​​moves to the unloading slot 3, the pressure plate 8 on the surface of the turntable 16 rotates to the top surface of the connecting plate 17. Then the turntable 16 continues to rotate, driving the pressure rod 19 on its surface to press the connecting plate 17, and the connecting plate 17 will then press... The pressure plate 8 and spring 18 are pressed, which allows the pressure plate 8 to push the vegetable seedlings out of the placement slot 5. Then, the turntable 16 drives the pressure rod 19 to continue rotating, and eventually the pressure rod 19 moves away from the connecting plate 17. The compressed spring 18 is restored, and the connecting plate 17 and the pressure plate 8 are disengaged from the placement slot 5, so that the movement of the feeding plate 4 is no longer obstructed. Through the cooperation of the drive rod 14, gear set one, gear set two, intermittent gear 15, turntable 16 and pressure rod 19, the movement of the feeding plate 4 and the pressing of the pressure plate 8 are both driven by the single power source of the drive rod 14. This saves the cost of the embodiment of the invention and avoids the coordination problem of using multiple power sources, and avoids the conflict between the movement of the feeding plate 4 and the pressing of the pressure plate 8.

[0024] like Figure 1 , Figure 2 , Figure 4 and Figure 6 As shown, a feeding cylinder 20 is fixedly connected to the top surface of the support plate 1, away from the side of the covering wheel 13; a discharge port 21 is provided at the bottom of the feeding cylinder 20, near the mounting plate 2; the height of the groove of the discharge port 21 is the same as the thickness of the feeding plate 4; both ends of the feeding plate 4 are inlaid with magnetic plates 22; during operation, when the feeding plate 4 at the mounting plate 2 moves, because both ends of the feeding plate 4 are inlaid with magnetic plates 22, the feeding plate 4 at the mounting plate 2 will attract the feeding plate 4 at the bottom of the feeding cylinder 20, and make the feeding plate 4 at the feeding cylinder 20 and the feeding plate 4 at the mounting plate 2 move synchronously. After the feeding plate 4 at the mounting plate 2 has completed all the feeding, its... The feeding plate 4, which is attached to one end of the feeding cylinder 20, will be completely pulled out of the discharge port 21 at the bottom of the feeding cylinder 20 and moved to the mounting plate 2 for the next round of feeding. At this time, the user only needs to remove the feeding plate 4 that has been fed, so as not to hinder the feeding operation of the new feeding plate 4. At the same time, when the feeding plate 4 at the bottom of the feeding cylinder 20 is completely pulled out of the feeding cylinder 20, the top feeding plate 4 will fall to the bottom of the feeding cylinder 20 due to gravity. At this time, its end can be connected to the feeding plate 4 at the mounting plate 2 through the magnetic plate 22, thereby realizing the continuous feeding operation of the feeding plate 4, thereby reducing the feeding frequency of the user and reducing the difficulty of the user's operation.

[0025] like Figure 2 , Figure 4 and Figure 6 As shown, the bottom surface of the feeding plate 4 has limiting grooves 23 on both sides; the top surface of the support plate 1 is fixedly connected to guide plates 24 at the corresponding positions of the limiting grooves 23, and the guide plates 24 are adapted to the limiting grooves 23; during operation, when the feeding plate 4 at the bottom of the feeding cylinder 20 slides on the surface of the support plate 1, the two guide plates 24 on the top surface of the support plate 1 will be inserted into the limiting grooves 23 on both sides of the feeding plate 4, thereby restricting the position of the feeding plate 4, thus preventing the feeding from being tilted, which would prevent the feeding plate 4 from being properly inserted into the gap between the mounting plate 2 and the support plate 1.

[0026] like Figures 4 to 5As shown, multiple evenly arranged rollers 25 are rotatably connected within the limiting groove 23; a limiting plate 26 is fixedly connected to the top surface of the feeding plate 4 at the corresponding position of the limiting groove 23, and the limiting plate 26 is adapted to the limiting groove 23; the discharge port 21 and the mounting plate 2 are both adapted to the limiting plate 26; during operation, when the feeding plates 4 are stacked one by one in the feeding cylinder 20, the limiting plate 26 on the top surface of the bottom feeding plate 4 will insert into the limiting groove 23 on the bottom surface of its top feeding plate 4, thereby ensuring that the entire stack of feeding plates 4 in the feeding cylinder 20 is kept in place. The feeding plates are kept neatly arranged so that after the bottom feeding plate 4 is removed, the top feeding plate can fall exactly in the position of the original bottom feeding plate 4. This allows the limiting grooves 23 on both sides of the falling feeding plate 4 to fit onto the guide plate 24, thus ensuring that the feeding plates 4 can be fed neatly in sequence. At the same time, when the limiting plate 26 and the guide plate 24 slide in the limiting groove 23, the roller 25 in the limiting groove 23 can contact them, reducing the friction during movement and thus reducing the wear on the feeding plate 4, the limiting plate 26 and the guide plate 24.

[0027] like Figure 6 As shown, pull rods 27 are slidably connected to the inner walls of both sides of the feeding cylinder 20; the bottoms of the two pull rods 27 are fixedly connected to a support plate 28; the top surface of the support plate 1 and the surface of the guide plate 24 are provided with clearance grooves 29 at the corresponding positions of the support plate 28; during operation, when the user first feeds the feeding plate 4 into the feeding cylinder 20, the user needs to pull the pull rods 27 on both sides, so that the pull rods 27 drive the support plate 28 to rise, and then the user places the feeding plate 4 on the support plate 28, and then the user slowly lowers the pull rods 27, so that the pull rods 27 drive the support plate 28 and the feeding plate 4 to slowly descend to the top surface of the support plate 1, and the support plate 28 is inserted into the clearance groove 29. This can prevent the user from directly putting the feeding plate 4 into the feeding cylinder 20 through the opening at the top, which would cause the feeding plate 4 to directly hit the top surface of the support plate 1, and cause the vegetable seedlings at the feeding plate 4 to fall out of the placement groove 5.

[0028] like Figure 4 , Figure 8 and Figure 9As shown, a slot 30 is provided on one side of the feeding plate 4; a pull plate 31 is slidably connected in the slot 30; a connecting groove 32 is provided on the surface of the pull plate 31 at the corresponding position of the placement groove 5; the connecting groove 32 has the same size as the placement groove 5; pairs of spring pieces 6 are respectively fixed to the inner walls on both sides of each connecting groove 32; the pairs of spring pieces 6 are all inclined and arranged in a V-shape between them; during operation, in order to facilitate the user to place the vegetable seedlings into the placement groove 5, the user can, before placing the vegetable seedlings, Pull the pull plate 31 out of the slot 30. Since the spring piece 6 is fixed to the inner wall of the connecting groove 32 on the surface of the insert plate, the spring piece 6 will also leave the slot 30 along with the pull plate 31. As a result, there will be no more spring piece 6 blocking the opening of the placement slot 5. As a result, the user can more easily put the vegetable seedlings into the placement slot 5. After all the vegetable seedlings have been placed, the user only needs to insert the pull plate 31 back into the slot 30 to complete the feeding operation of the feeding plate 4. This makes feeding easier for the user and reduces the operational difficulty of this embodiment of the invention.

[0029] like Figures 8 to 9 As shown, the bottom surface of the pressure plate 8 is provided with a protective groove 33; the protective groove 33 is V-shaped, and the width of its bottom opening is greater than the width of its top; during operation, when the connecting plate 17 drives the pressure plate 8 to press against the placement groove 5, since the paired spring pieces 6 form a V-shape on one side, the strip-shaped vegetable seedlings will concentrate at the bottom of the paired spring pieces 6. The protective groove 33 on the bottom surface of the pressure plate 8 will fit perfectly on the top surface of the vegetable seedlings, and the pressure plate 8 will squeeze the spring pieces 6, causing the spring pieces 6 to deflect, thereby allowing the vegetable seedlings to fall through the gap between the paired spring pieces 6, thus avoiding the vegetable seedlings from directly squeezing the spring pieces 6, thereby avoiding damage to the vegetable seedlings due to squeezing.

[0030] like Figure 4 , Figure 8 and Figure 9 As shown, the area of ​​the magnet plate 22 near the slot opening of the slot 30 is smaller than that of the magnet plate 22 away from the slot opening of the slot 30; a pair of symmetrically arranged insertion holes 34 are provided at the bottom of the slot 30, and the insertion holes 34 are connected to the surface of the magnet plate 22; a metal post 35 is fixedly connected to one end of the pull plate 31 near the insertion hole 34; the metal post 35 is adapted to the insertion hole 34, and the metal post 35 is made of magnetizable metal; during operation, when the user inserts the pull plate 31 into the slot 30, the metal post 35 at the end of the pull plate 31 will be inserted into the insertion hole 34 at the bottom of the slot 30. Since the insertion hole 34 is connected to the magnet plate 22, the metal post 35 will eventually contact the magnet plate 22, thereby attracting the metal post 35, thus fixing the pull plate 31 in the slot 30, thereby preventing the pull plate 31 from moving during the feeding process, which would cause the connecting groove 32 on the surface of the pull plate 31 to be misaligned with the connecting groove 32 on the surface of the feeding plate 4.

[0031] like Figure 1 and Figure 10 As shown, a hollow wheel 36 is rotatably connected to the bottom surface of the support plate 1 on the side of the covering wheel 13 away from the guide plate 24; a mixing bead 37 is provided inside the hollow wheel 36; and a liquid outlet hole 38 is opened on the surface of the hollow wheel 36. During operation, before cultivating vegetable seedlings, nutrient solution needs to be injected into the hollow wheel 36. After the covering wheel 13 covers the vegetable seedlings with soil, the hollow wheel 36 will pass over the soil on the top surface of the vegetable seedlings. During the passage of the hollow wheel 36, the mixing bead 37 will roll inside the hollow wheel 36, thereby causing the hollow wheel 36 to vibrate and causing the nutrient solution inside the hollow wheel 36 to seep out, thereby providing necessary nutrition for the vegetable seedlings and promoting the further growth of the vegetable seedlings.

[0032] During operation, to ensure that the feeding rate of vegetable seedlings matches the seedling placement rate, thereby reducing the occurrence of missed or excessive seedlings, this embodiment of the invention can be used. Firstly, before transplanting the vegetable seedlings, the user needs to place each vegetable seedling individually into its respective placement slot 5 on the surface of the feeding plate 4. The spring clip 6 prevents the vegetable seedlings from detaching from the slot 5. Furthermore, because the vegetable seedlings are elongated and the through-slot 7 is smaller than the placement slot 5, the vegetable seedlings will not detach from the through-slot 7 either. Thus, the vegetable seedlings are stored in the placement slots 5 on the surface of the feeding plate 4. Subsequently, the user then connects this embodiment of the invention to a tractor... Next, the tractor acts as the power source for forward movement, propelling the embodiment of the invention forward along the field. During this process, the drive assembly moves the feeding plate 4 to the mounting plate 2. Subsequently, the pressure plate 8 presses down and passes through the mounting plate 2 and the through groove 7 into the placement groove 5 of the feeding plate 4, thereby squeezing the vegetable seedlings and spring pieces 6 in the placement groove 5. This causes the spring pieces 6 to deflect, allowing the vegetable seedlings to fall between the pairs of spring pieces 6. The vegetable seedlings then pass through the discharge groove 3 and fall onto the chain assembly 9, where they are finally caught by the receiving plate 10 on the surface of the chain assembly 9. Each vegetable seedling falls into only one receiving plate 10. Subsequently, the chain assembly 9 drives... The receiving plate 10 on its surface moves, feeding the vegetable seedlings one by one to the guide plate 24. During the movement of the present invention, the shovel plate 12 on one side of the guide plate 24 will dig trenches in the field for transplanting, and the vegetable seedlings in the guide will fall evenly into the transplanting trenches one by one. Then, after the soil covering wheel 13 passes through the transplanting trench, it will push the soil on both sides of the trench to the middle of the transplanting trench, thereby covering the vegetable seedlings and completing the transplanting operation. When the vegetable seedlings in one row of placement slots 5 of the feeding plate 4 are used up, the drive component will drive the feeding plate 4 to move towards the mounting plate 2, and move the next row of placement slots 5 of the feeding plate 4. Moved directly below mounting plate 2, the vegetable seedlings contained in the receiving plate 10 on the surface of chain assembly 9 will move to the feeding trough 3. Then, the pressing plate 8 will press into the placement trough 5 again, pressing the vegetable seedlings in the placement trough 5 back into the receiving plate 10. This completes the feeding of vegetable seedlings to the receiving plate 10 again. The above operation is repeated, and the vegetable seedlings can be transplanted evenly to the field one by one. Through the cooperation of the pressing plate 8, feeding and drive components, manual feeding is no longer required, thus avoiding the occurrence of missing seedlings and multiple seedlings due to the unstable feeding rate of manual feeding. This ensures both transplanting quality and transplanting efficiency.

[0033] When the chain assembly 9 needs to work, the servo motor drives the drive rod 14 to rotate, and the drive rod 14 drives the chains on both sides to rotate synchronously in the same direction via the belt. While the drive rod 14 drives the chain assembly 9 to work, the drive rod 14 also drives the intermittent gear 15 to rotate via the gear assembly. After the vegetable seedlings in the row of placement slots 5 of the feeding plate 4 are unloaded, the intermittent gear 15 rotates exactly one revolution and meshes with the side of the feeding plate 4. This moves the next row of placement slots 5 on the surface of the feeding plate 4 to the mounting plate 2, preparing for the unloading of the next batch of vegetable seedlings. At the same time, the drive rod 14 also drives the turntable 16 to rotate, so that after the next row of placement slots 5 containing vegetable seedlings moves to the unloading slot 3, the pressure plate 8 on the surface of the turntable 16 rotates to the top surface of the connecting plate 17. Then the turntable 16 continues to rotate. The rotating disc 16 drives the pressure rod 19 on its surface to press the connecting plate 17, which in turn presses the pressure plate 8 and the spring 18, thus allowing the pressure plate 8 to push the vegetable seedlings in the placement slot 5 out for placement. Subsequently, the rotating disc 16 drives the pressure rod 19 to continue rotating, and eventually the pressure rod 19 moves away from the connecting plate 17. The compressed spring 18 recovers and drives the connecting plate 17 and the pressure plate 8 to disengage from the placement slot 5, so that the movement of the feeding plate 4 is no longer obstructed. Through the cooperation of the drive rod 14, gear set one, gear set two, intermittent gear 15, rotating disc 16 and pressure rod 19, the movement of the feeding plate 4 and the pressing of the pressure plate 8 are both driven by the single power source of the drive rod 14. This saves the cost of the embodiment of the present invention and avoids the coordination problem of using multiple power sources, thus avoiding the conflict between the movement of the feeding plate 4 and the pressing of the pressure plate 8.

[0034] When the feeding plate 4 at mounting plate 2 moves, since both ends of the feeding plate 4 are embedded with magnetic plates 22, the feeding plate 4 at mounting plate 2 will attract the feeding plate 4 at the bottom of the feeding cylinder 20, causing the feeding plate 4 at the feeding cylinder 20 to move synchronously with the feeding plate 4 at mounting plate 2. After the feeding plate 4 at mounting plate 2 has completed all the feeding, the feeding plate 4 attracted to the end near the feeding cylinder 20 will be completely pulled out of the discharge port 21 at the bottom of the feeding cylinder 20 and moved to mounting plate 2, thus proceeding to the next step. In one round of feeding, the user only needs to remove the feeding plate 4 that has been fed, so as not to obstruct the feeding operation of the new feeding plate 4. At the same time, when the feeding plate 4 at the bottom of the feeding cylinder 20 is completely pulled out of the feeding cylinder 20, the top feeding plate 4 will fall to the bottom of the feeding cylinder 20 due to gravity. At this time, its end can be connected to the feeding plate 4 at the mounting plate 2 through the magnetic plate 22, thereby realizing the continuous feeding operation of the feeding plate 4, thereby reducing the feeding frequency of the user and reducing the difficulty of operation for the user.

[0035] When the feeding plate 4 at the bottom of the feeding cylinder 20 slides on the surface of the support plate 1, the two guide plates 24 on the top surface of the support plate 1 will be inserted into the limiting grooves 23 on both sides of the feeding plate 4, thereby restricting the position of the feeding plate 4 and preventing the feeding from being tilted, which would prevent the feeding plate 4 from being properly inserted into the gap between the mounting plate 2 and the support plate 1.

[0036] When the feeding plates 4 are stacked one by one in the feeding cylinder 20, the limiting plate 26 on the top surface of the bottom feeding plate 4 will insert into the limiting groove 23 on the bottom surface of the top feeding plate 4. This keeps the stack of feeding plates 4 in the feeding cylinder 20 neat and orderly. After the bottom feeding plate 4 is removed, the top feeding plate can fall exactly in the position of the original bottom feeding plate 4. Thus, the limiting grooves 23 on both sides of the falling feeding plate 4 can be locked onto the guide plate 24. This ensures that the feeding plates 4 can be fed neatly in sequence. At the same time, when the limiting plate 26 and the guide plate 24 slide in the limiting groove 23, the roller 25 in the limiting groove 23 can contact them and reduce the friction during movement, thereby reducing the wear on the feeding plate 4, the limiting plate 26 and the guide plate 24.

[0037] When the user first loads the feeding plate 4 into the feeding cylinder 20, the user needs to pull the levers 27 on both sides, so that the levers 27 drive the support plate 28 to rise. Then the user places the feeding plate 4 on the support plate 28, and then the user slowly lowers the levers 27, so that the levers 27 drive the support plate 28 and the feeding plate 4 to slowly descend to the top surface of the support plate 1, and the support plate 28 is inserted into the relief groove 29. This can prevent the user from directly putting the feeding plate 4 into the opening at the top of the feeding cylinder 20, which would cause the feeding plate 4 to directly hit the top surface of the support plate 1, and cause the vegetable seedlings at the feeding plate 4 to fall out of the placement groove 5.

[0038] To facilitate the user's placement of vegetable seedlings into the placement slot 5, the user can pull the pull plate 31 out of the slot 30 before placing the seedlings. Since the spring piece 6 is fixed to the inner wall of the connecting slot 32 on the surface of the insert plate, the spring piece 6 will also leave the slot 30 along with the pull plate 31. Thus, there will be no more spring piece 6 blocking the opening of the placement slot 5, making it easier for the user to place the vegetable seedlings into the placement slot 5. After all the seedlings have been placed, the user only needs to insert the pull plate 31 back into the slot 30 to complete the feeding operation of the feeding plate 4. This facilitates the user's feeding and reduces the operational difficulty of this embodiment of the invention.

[0039] When the connecting plate 17 drives the pressure plate 8 to press against the placement groove 5, the paired spring pieces 6 form a V-shape on one side, so the strip-shaped vegetable seedlings will concentrate at the bottom of the paired spring pieces 6. The protective groove 33 on the bottom surface of the pressure plate 8 will fit perfectly on the top surface of the vegetable seedlings, and the pressure plate 8 will squeeze the spring pieces 6, causing the spring pieces 6 to deflect, thereby allowing the vegetable seedlings to fall through the gap between the paired spring pieces 6. This avoids the vegetable seedlings directly squeezing the spring pieces 6, thus preventing damage to the vegetable seedlings due to squeezing.

[0040] When the user inserts the pull plate 31 into the slot 30, the metal post 35 at the end of the pull plate 31 will be inserted into the insertion hole 34 at the bottom of the slot 30. Since the insertion hole 34 is connected to the magnetic plate 22, the metal post 35 will eventually come into contact with the magnetic plate 22 and thus attract the metal post 35, thereby fixing the pull plate 31 in the slot 30. This prevents the pull plate 31 from moving during the feeding process, which would cause the connecting groove 32 on the surface of the pull plate 31 to be misaligned with the connecting groove 32 on the surface of the feeding plate 4.

[0041] Before cultivating vegetable seedlings, nutrient solution needs to be injected into the hollow wheel 36. After the soil covering wheel 13 covers the vegetable seedlings with soil, the hollow wheel 36 will pass over the soil on the top surface of the vegetable seedlings. During the process of the hollow wheel 36 passing over the soil, the mixing beads 37 will roll inside the hollow wheel 36, which will cause the hollow wheel 36 to vibrate and cause the nutrient solution inside the hollow wheel 36 to seep out, thereby providing the necessary nutrition for the vegetable seedlings and promoting the further growth of the vegetable seedlings.
