DETAILED DESCRIPTION

[0032] In order to make the technical means, creative features, purposes and effects realized by the present application easy to understand, the present application is further described below in combination with specific embodiments.

[0033] As Figures 1 to 4As shown, the vegetable seedling planting device comprises a tractor traction 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 plates 2 and the bottom support plate 1, a discharging groove 3 is formed in 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 uniformly arranged placing grooves 5 are formed in the bottom surface of the feeding plate 4, a pair of symmetrically arranged elastic sheets 6 are installed at the bottom of the placing grooves 5, a through groove 7 is formed in the top surface of the feeding plate 4 at the corresponding position of the placing groove 5, a plurality of uniformly arranged pressing plates 8 are slidingly connected to the top surface of the mounting plate 2, the pressing plates 8 and the through grooves 7 at the bottom thereof are arranged in one-to-one correspondence, and the through grooves 7 are smaller than the placing grooves 5, a chain set 9 is installed at the bottom of the support plate 1 at the corresponding position of the discharging groove 3, a plurality of uniformly arranged supporting plates 10 are fixedly connected to the surface of the chain set 9, a pair of material guiding plates 11 are fixedly connected to the bottom surface of the support plate 1 at the corresponding positions of the two chain sets 9, a shovel plate 12 is fixedly connected to one side of the bottom of the material guiding plate 11, a soil covering wheel 13 is installed on the bottom surface of the support plate 1 at the side of the material guiding plate 11 away from the inserting plate, and the chain set 9, the feeding plate 4 and the pressing plate 8 are all driven by a driving assembly through a motor.In operation, in order to ensure that the feeding rate of the vegetable seedlings is consistent with the planting rate, thereby reducing the occurrence of missing seedlings or too many seedlings, the embodiment of the present application can be used. First, before transplanting the vegetable seedlings, the user needs to place each vegetable seedling separately into each placement slot 5 on the surface of the feeding plate 4, and the spring piece 6 prevents the vegetable seedlings from falling out of the slot of the placement slot 5. Since the vegetable seedlings are in a strip shape and the through slot 7 is smaller than the placement slot 5, the vegetable seedlings will not fall out of the through slot 7. Thus, the vegetable seedlings are stored in the placement slot 5 on the surface of the feeding plate 4. Then, the user connects the embodiment of the present application to the tractor, which provides the power source for the forward movement of the tractor, and drives the embodiment of the present application to move forward along the field. In the process, the driving assembly moves the feeding plate 4 to the mounting plate 2, and then the pressing plate 8 is pressed down and passes through the mounting plate 2 and the through slot 7 into the placement slot 5 of the feeding plate 4, thereby pressing the vegetable seedlings and the spring piece 6 in the placement slot 5 and finally causing the spring piece 6 to deflect, allowing the vegetable seedlings to fall between the pair of spring pieces 6. Then, the vegetable seedlings pass through the discharging slot 3 and fall onto the chain set 9, and are finally caught by the receiving plate 10 on the surface of the chain set 9. Each vegetable seedling will only fall into one receiving plate 10. Then, the chain set 9 moves the receiving plate 10 on its surface, and the vegetable seedlings in the receiving plate 10 are sent one by one to the guide plate 24. In the process of the present application, the shovel plate 12 on one side of the guide plate 24 will shovel a groove for transplanting in the field, and the vegetable seedlings in the guide plate will fall into the transplanting groove one by one. Then, after the covering wheel 13 passes through the transplanting groove, it will push the soil on both sides of the groove to the middle of the transplanting groove, thereby covering the vegetable seedlings, thereby completing the transplanting operation of the vegetable seedlings. When the vegetable seedlings in the placement slot 5 of the feeding plate 4 are used up, the driving assembly drives the feeding plate 4 to move towards the mounting plate 2, and the next row of placement slots 5 of the feeding plate 4 is moved to the mounting plate 2. At this time, part of the vegetable seedlings in the receiving plate 10 on the surface of the chain set 9 will move to the discharging slot 3. Then, the pressing plate 8 is pressed into the placement slot 5 again, and the vegetable seedlings in the placement slot 5 are pressed into the receiving plate 10 again, thereby completing the feeding of the vegetable seedlings to the receiving plate 10 again. Then, the above operation is repeated, and the vegetable seedlings can be transplanted into the field one by one. Through the cooperation of the pressing plate 8, the feeding assembly, and the driving assembly, manual feeding is no longer needed, thereby avoiding the occurrence of missing seedlings or too many seedlings due to the instability of manual feeding rate, thereby ensuring the transplanting quality and efficiency.

[0034] As Figures 1 to 3As shown, the driving assembly comprises a driving rod 14; the driving rod 14 is rotationally connected at the bottom surface of the support plate 1 and is driven by a servo motor; the driving rod 14 is connected with the chain set 9 through a belt; the top surface of the support plate 1 is rotationally connected with a pair of intermittent gears 15, and the intermittent gears 15 are connected with the driving rod 14 through a gear set one; after the chain set 9 driven by the driving rod 14 guides all the vegetable seedlings at the receiving plate 10 into the pair of guide plates 24, the intermittent gears 15 just rotate a circle, thereby moving the next row of placing grooves 5 on the feeding plate 4 to the discharging groove 3; the two intermittent gears 15 are respectively meshed with the feeding plate 4 close to the side of the intermittent gears 15; the top surface of the support plate 1 is rotationally connected with a rotating turntable 16 between the two mounting plates 2, and the turntable 16 is connected with the driving rod 14 through a gear set two; the top surface of the pressing plate 8 is fixedly connected with a connecting plate 17; the connecting plate 17 and the mounting plate 2 are fixedly connected with a spring 18; the side of the turntable 16 close to the connecting plate 17 is fixedly connected with a pressing rod 19; after the chain set 9 driven by the driving rod 14 guides all the vegetable seedlings at the receiving plate 10 into the pair of guide plates 24, the turntable 16 just rotates a circle, thereby making the pressing plate 8 on the surface of the turntable 16 extrude the connecting plate 17 once; when the chain set 9 needs to work, the servo motor drives the driving rod 14 to rotate, and the driving rod 14 drives the chains on both sides to rotate synchronously and in the same direction through the belt, while the driving rod 14 drives the intermittent gears 15 to rotate through the gear assembly one, so that after the vegetable seedlings in the row of placing grooves 5 on the feeding plate 4 are discharged, the intermittent gears 15 just rotate a circle and mesh with the side surface of the feeding plate 4, thereby moving the next row of placing grooves 5 on the surface of the feeding plate 4 to the mounting plate 2 and preparing for the discharge of the next batch of vegetable seedlings, at the same time, the driving rod 14 drives the turntable 16 to rotate, so that the next row of placing grooves 5 containing the vegetable seedlings are moved to the discharging groove 3, the pressing plate 8 on the surface of the turntable 16 just rotates to the top surface of the connecting plate 17, then the turntable 16 continues to rotate and drives the pressing rod 19 on the surface thereof to extrude the connecting plate 17, the connecting plate 17 extrudes the pressing plate 8 and the spring 18, thereby making the pressing plate 8 push out the vegetable seedlings in the placing groove 5, then the turntable 16 drives the pressing rod 19 to continue to rotate and finally makes the pressing rod 19 away from the connecting plate 17, the extruded spring 18 recovers and drives the connecting plate 17 and the pressing plate 8 to be separated from the placing groove 5, so that the movement of the feeding plate 4 is no longer hindered, through the cooperation of the driving rod 14, the gear set one, the gear set two, the intermittent gears 15, the turntable 16 and the pressing rod 19, the movement of the feeding plate 4 and the extrusion and discharge of the pressing plate 8 are both driven by the driving rod 14, which saves the cost of the embodiment of the application and avoids the coordination problem of using multiple power sources and the conflict between the movement of the feeding plate 4 and the extrusion and discharge of the pressing plate 8.

[0035] AsFigure 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.

[0036] 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.

[0037] like Figures 4 to 5As shown, the limiting groove 23 is rotatably connected with a plurality of evenly arranged rollers 25; the top surface of the feeding plate 4 is fixedly connected with a limiting plate 26 at the corresponding position of the limiting groove 23, and the limiting plate 26 is matched with the limiting groove 23; the discharge port 21 and the mounting plate 2 are matched with the limiting plate 26; during operation, when the feeding plates 4 are stacked in the feeding cylinder 20 one by one, the limiting plate 26 on the top surface of the feeding plate 4 at the bottom is inserted into the limiting groove 23 on the bottom surface of the feeding plate 4 at the top, so that the whole stack of feeding plates 4 in the feeding cylinder 20 is kept neat, and then when the feeding plate 4 at the bottom is taken away, the feeding plate at the top can fall exactly on the position of the original feeding plate at the bottom, so that the limiting grooves 23 on both sides of the fallen feeding plate 4 can be buckled on the guide plate 24, thereby ensuring that the feeding plates 4 can be sequentially and neatly fed, and when the limiting plate 26 and the guide plate 24 slide in the limiting groove 23, the rollers 25 in the limiting groove 23 can contact with them and reduce the friction during movement, thereby reducing the wear of the feeding plate 4, the limiting plate 26 and the guide plate 24.

[0038] As shown in Figure 6 , the two side inner walls of the feeding cylinder 20 are slidingly connected with pull rods 27; the bottoms of the two pull rods 27 are fixedly connected with a supporting plate 28; the top surface of the supporting plate 1 and the surface of the guide plate 24 are both provided with a letting-in groove 29 at the corresponding position of the supporting plate 28; during operation, when the user initially feeds the feeding plates 4 into the feeding cylinder 20, the user needs to pull the two pull rods 27, so that the pull rods 27 drive the supporting plate 28 to rise, then the user places the feeding plates 4 on the supporting plate 28, and then the user slowly lowers the pull rods 27, so that the pull rods 27 drive the supporting plate 28 and the feeding plates 4 to slowly descend to the top surface of the supporting plate 1, and the supporting plate 28 is inserted into the letting-in groove 29, thereby avoiding the user directly placing the feeding plates 4 from the opening at the top of the feeding cylinder 20, so that the feeding plates 4 directly hit the top surface of the supporting plate 1, and the vegetable seedlings at the feeding plates 4 fall out of the placing grooves 5.

[0039] As shown in Figure 4 , Figure 8 and Figure 9As shown, one side of the feeding plate 4 is provided with a slot 30; the slot 30 is slidably connected with a pull plate 31; the surface of the pull plate 31 is provided with a communication groove 32 at the corresponding position of the placing groove 5; the communication groove 32 is consistent with the size of the placing groove 5; a pair of the elastic sheets 6 are fixedly connected at the inner walls of the two sides of each communication groove 32; the pair of the elastic sheets 6 are obliquely arranged, and the pair of the elastic sheets 6 are arranged in a V-shaped structure; during operation, in order to facilitate the user to put the vegetable seedlings into the placing groove 5, the user can pull out the pull plate 31 from the slot 30 before placing the vegetable seedlings, since the elastic sheets 6 are fixedly connected to the inner walls of the communication groove 32 on the surface of the pull plate, the elastic sheets 6 will also leave the slot 30 together with the pull plate 31, so that the slot opening of the placing groove 5 will not be blocked by the elastic sheets 6, thereby the user can more conveniently put the vegetable seedlings into the placing groove 5, and when the vegetable seedlings are all placed, the user only needs to insert the pull plate 31 back into the slot 30, so as to complete the feeding operation of the feeding plate 4, thereby facilitating the feeding of the user and reducing the operation difficulty of the embodiment.

[0040] As shown in Figures 8 to 9 , the bottom surface of the pressing plate 8 is provided with a protection groove 33; the protection groove 33 is arranged in a V-shaped structure, and the width of the bottom opening is greater than the width of the top; during operation, when the connecting plate 17 drives the pressing plate 8 to press the placing groove 5, since the pair of elastic sheets 6 form a V-shaped structure on one side, the strip-shaped vegetable seedlings will be concentrated at the bottom of the pair of elastic sheets 6, the protection groove 33 on the bottom surface of the pressing plate 8 will be just buckled on the top surface of the vegetable seedlings, and the elastic sheets 6 will be deflected by the pressing plate 8, so that the vegetable seedlings fall down from the gap between the pair of elastic sheets 6, thereby avoiding the direct extrusion of the vegetable seedlings on the elastic sheets 6, so as to avoid the damage of the vegetable seedlings due to extrusion.

[0041] As shown in Figure 4 , Figure 8 and Figure 9 , the area of the magnet plate 22 near the slot opening of the slot 30 is smaller than 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 communicated to the surface of the magnet plate 22; a metal column 35 is fixedly connected to one end of the pull plate 31 near the insertion hole 34; the metal column 35 is adapted to the insertion hole 34, and the metal column 35 is made of magnetizable metal; during operation, when the user inserts the pull plate 31 into the slot 30, the metal column 35 at the end of the pull plate 31 will be inserted into the insertion hole 34 at the bottom of the slot 30, and since the insertion hole 34 is communicated with the magnet plate 22, the metal column 35 will finally contact the magnet plate 22, thereby attracting the metal column 35, so that the pull plate 31 is fixed in the slot 30, thereby avoiding the movement of the pull plate 31 during the feeding movement, and causing the communication groove 32 on the surface of the pull plate 31 to be out of position with the communication groove 32 on the surface of the feeding plate 4.

[0042] As Figure 1 and Figure 10 The bottom surface of the support plate 1 is rotatably connected with a hollow wheel 36 on the side away from the guide plate 24, as shown in the drawings. The inside of the hollow wheel 36 is provided with mixed beads 37. The surface of the hollow wheel 36 is provided with liquid outlet holes 38. During operation, before the cultivation of the vegetable seedlings, the hollow wheel 36 needs to be injected with nutrient solution. After the soil covering wheel 13 covers the soil on the vegetable seedlings, the hollow wheel 36 will pass through the soil on the top surface of the vegetable seedlings. During the passing process of the hollow wheel 36, the mixed beads 37 will roll in the hollow wheel 36, thereby causing the hollow wheel 36 to vibrate, so that the nutrient solution in the hollow wheel 36 seeps out, thereby providing the necessary nutrients for the vegetable seedlings and promoting the further growth of the vegetable seedlings.

[0043] In operation, in order to ensure that the feeding rate of the vegetable seedlings is consistent with the planting rate, thereby reducing the occurrence of missing seedlings or too many seedlings, the embodiment of the present application can be used. First, before transplanting the vegetable seedlings, the user needs to place each vegetable seedling separately into each placement slot 5 on the surface of the feeding plate 4, and the spring piece 6 prevents the vegetable seedlings from falling out of the slot of the placement slot 5. Since the vegetable seedlings are in a strip shape and the through slot 7 is smaller than the placement slot 5, the vegetable seedlings will not fall out of the through slot 7. Thus, the vegetable seedlings are stored in the placement slot 5 on the surface of the feeding plate 4. Then, the user connects the embodiment of the present application to the tractor, which provides the power source for the forward movement of the tractor, and drives the embodiment of the present application to move forward along the field. In the process, the driving assembly moves the feeding plate 4 to the mounting plate 2, and then the pressing plate 8 is pressed down and passes through the mounting plate 2 and the through slot 7 into the placement slot 5 of the feeding plate 4, thereby pressing the vegetable seedlings and the spring piece 6 in the placement slot 5 and finally causing the spring piece 6 to deflect, allowing the vegetable seedlings to fall between the pair of spring pieces 6. Then, the vegetable seedlings pass through the discharging slot 3 and fall onto the chain set 9, and are finally caught by the receiving plate 10 on the surface of the chain set 9. Each vegetable seedling will only fall into one receiving plate 10. Then, the chain set 9 moves the receiving plate 10 on its surface, and the vegetable seedlings in the receiving plate 10 are sent one by one to the guide plate 24. In the process of the present application, the shovel plate 12 on one side of the guide plate 24 will shovel a groove for transplanting in the field, and the vegetable seedlings in the guide plate will fall into the transplanting groove one by one. Then, after the covering wheel 13 passes through the transplanting groove, it will push the soil on both sides of the groove to the middle of the transplanting groove, thereby covering the vegetable seedlings, thereby completing the transplanting operation of the vegetable seedlings. When the vegetable seedlings in the placement slot 5 of the feeding plate 4 are used up, the driving assembly drives the feeding plate 4 to move towards the mounting plate 2, and the next row of placement slots 5 of the feeding plate 4 is moved to the directly below the mounting plate 2. At this time, part of the vegetable seedlings in the receiving plate 10 on the surface of the chain set 9 will move to the discharging slot 3. Then, the pressing plate 8 is pressed into the placement slot 5 again, and the vegetable seedlings in the placement slot 5 are pressed into the receiving plate 10 again, thereby completing the feeding of the vegetable seedlings to the receiving plate 10 again. Then, the above operation is repeated, and the vegetable seedlings can be transplanted into the field one by one. Through the cooperation of the pressing plate 8, the feeding assembly, and the driving assembly, manual feeding is no longer needed, thereby avoiding the occurrence of missing seedlings or too many seedlings due to the instability of manual feeding rate, thereby ensuring the transplanting quality and efficiency.

[0044] When the chain group 9 needs to work, the servo motor drives the driving rod 14 to rotate, and the driving rod 14 drives the two chains on the left and right sides to rotate synchronously and in the same direction through the belt. When the driving rod 14 drives the chain group 9 to work, the driving rod 14 also drives the intermittent gear 15 to rotate through the gear assembly one, so that the vegetables seedlings in the next row of the placing grooves 5 on the surface of the feeding plate 4 are moved to the mounting plate 2 after the vegetables seedlings in the row of the placing grooves 5 on the feeding plate 4 are discharged, and the next batch of vegetables seedlings are prepared for discharging. At the same time, the driving rod 14 also drives the rotating disc 16 to rotate, so that the next row of the placing grooves 5 containing the vegetables seedlings are moved to the discharging groove 3, and the pressing plate 8 on the surface of the rotating disc 16 is just rotated to the top surface of the connecting plate 17, and then the rotating disc 16 continues to rotate and drives the pressing rod 19 on the surface thereof to extrude the connecting plate 17, and the connecting plate 17 extrudes the pressing plate 8 and the spring 18, so that the pressing plate 8 can push the vegetables seedlings in the placing groove 5 out of the placing groove 5. Then the rotating disc 16 drives the pressing rod 19 to continue to rotate, and finally the pressing rod 19 is away from the connecting plate 17, the spring 18 is restored, and the connecting plate 17 and the pressing plate 8 are separated from the placing groove 5, so that the movement of the feeding plate 4 is no longer blocked. Through the cooperation of the driving rod 14, the gear assembly one, the gear assembly two, the intermittent gear 15, the rotating disc 16 and the pressing rod 19, the movement of the feeding plate 4 and the extrusion and discharging of the pressing plate 8 are driven by the driving rod 14, which saves the cost of the embodiment of the application and avoids the coordination problem of using multiple power sources and the conflict between the movement of the feeding plate 4 and the extrusion and discharging of the pressing plate 8.

[0045] When the feeding plate 4 at the mounting plate 2 moves, since the two ends of the feeding plate 4 are embedded with the magnet plate 22, the feeding plate 4 at the mounting plate 2 can attract the feeding plate 4 at the bottom of the feeding cylinder 20, and the feeding plate 4 at the mounting plate 2 can move synchronously with the feeding plate 4 at the bottom of the feeding cylinder 20. When the feeding plate 4 at the mounting plate 2 completes all the feeding, the feeding plate 4 at the end close to the feeding cylinder 20 is completely extracted from the discharging port 21 at the bottom of the feeding cylinder 20 and moves to the mounting plate 2, so as to perform the next round of discharging. At this time, the user only needs to remove the feeding plate 4 that has been discharged, so as not to hinder the new feeding plate 4 from discharging. At the same time, when the feeding plate 4 at the bottom of the feeding cylinder 20 is completely extracted from the feeding cylinder 20, the top feeding plate 4 falls to the bottom of the feeding cylinder 20 due to the action of gravity. At this time, the end thereof can be connected to the feeding plate 4 at the mounting plate 2 through the magnet plate 22, so as to realize the continuous feeding operation of the feeding plate 4, thereby reducing the feeding frequency of the user and the operation difficulty of the user.

[0046] 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 respectively insert into the limiting grooves 23 on both sides of the feeding plate 4, thereby limiting the position of the feeding plate 4, so as to avoid the skew of feeding, which causes the feeding plate 4 to be unable to be normally inserted into the gap between the mounting plate 2 and the support plate 1.

[0047] 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 feeding plate 4 at the bottom will insert into the limiting groove 23 on the bottom surface of the feeding plate 4 on the top, thereby making the whole stack of feeding plates 4 in the feeding cylinder 20 keep neat, and then making the feeding plate 4 on the top fall exactly on the position of the feeding plate 4 at the bottom which has been taken away, so that the limiting grooves 23 on both sides of the falling feeding plate 4 can be exactly buckled on the guide plates 24, thereby ensuring that the feeding plates 4 can be sequentially and neatly fed, and when the limiting plate 26 and the guide plate 24 slide in the limiting groove 23, the rollers 25 in the limiting groove 23 can be in contact with the two, and the friction force during movement can be reduced, thereby reducing the wear of the feeding plate 4, the limiting plate 26 and the guide plate 24.

[0048] When the user initially 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 supporting plate 28 to rise, and then the user places the feeding plate 4 on the supporting plate 28, and then the user slowly lowers the pull rods 27, which drive the supporting plate 28 and the feeding plate 4 to slowly descend to the top surface of the support plate 1, and make the supporting plate 28 insert into the accommodation groove 29, thereby avoiding the user directly putting the feeding plate 4 from the opening on the top of the feeding cylinder 20, which causes the feeding plate 4 to directly hit the top surface of the support plate 1, and causes the vegetable seedlings in the placing groove 5 to fall out.

[0049] In order to facilitate the user to put the vegetable seedlings into the placing groove 5, the user can pull out the pull plate 31 from the insertion slot 30 before placing the vegetable seedlings, since the elastic piece 6 is fixedly connected to the inner wall of the through groove 32 on the surface of the insertion plate, so the elastic piece 6 will also leave the insertion slot 30 together with the pull plate 31, thereby the slot opening of the placing groove 5 will not be blocked by the elastic piece 6, so that the user can more conveniently put the vegetable seedlings into the placing groove 5, and when the vegetable seedlings are all placed, the user only needs to insert the pull plate 31 back into the insertion slot 30, so as to complete the feeding operation of the feeding plate 4, thereby facilitating the user to feed and reducing the operation difficulty of the embodiment of the method.

[0050] When the connecting plate 17 drives the pressing plate 8 to press the placing groove 5, the strip-shaped vegetable seedlings will be concentrated at the bottom of the pair of elastic sheets 6 due to the V-shaped structure of the pair of elastic sheets 6, the protection groove 33 at the bottom of the pressing plate 8 will be just buckled on the top surface of the vegetable seedlings, and the elastic sheets 6 will be deflected by the pressing plate 8, so that the vegetable seedlings will fall from the gap between the pair of elastic sheets 6, thereby avoiding the direct extrusion of the vegetable seedlings on the elastic sheets 6, and avoiding the damage of the vegetable seedlings caused by the extrusion.

[0051] When the user inserts the pulling plate 31 into the insertion slot 30, the metal column 35 at the end of the pulling plate 31 will be inserted into the insertion hole 34 at the bottom of the insertion slot 30, and since the insertion hole 34 is in communication with the magnet plate 22, the metal column 35 will finally contact the magnet plate 22, thereby attracting the metal column 35, so that the pulling plate 31 is fixed in the insertion slot 30, thereby avoiding the movement of the pulling plate 31 during the movement of the feeding, and causing the communication groove 32 on the surface of the pulling plate 31 to be out of position with the communication groove 32 on the surface of the feeding plate 4.

[0052] Before the cultivation of the vegetable seedlings, the hollow wheel 36 needs to be injected with nutrient solution, and after the soil covering wheel 13 covers the soil on the vegetable seedlings, the hollow wheel 36 will pass through the soil on the top surface of the vegetable seedlings, and during the passing of the hollow wheel 36, the mixed beads 37 will roll in the hollow wheel 36, thereby causing the hollow wheel 36 to vibrate, so that the nutrient solution in the hollow wheel 36 is exuded, thereby providing the necessary nutrients for the vegetable seedlings and promoting the further growth of the vegetable seedlings.
