Description

Technical Field

[0001] This application relates to the field of seedling extraction technology, specifically to a continuous ejection device and a seedling transplanter. Background Technology

[0002] Vegetable seedlings may die due to many factors during their growth, resulting in a low survival rate. Transplanting seedlings in pots has the advantages of rapid greening and a shorter growth cycle. Transplanting technology can effectively avoid climate problems such as low temperature and frost, thus improving the survival rate of vegetable seedlings.

[0003] Currently, the seedling picking device in existing vegetable transplanters still requires manual operation. Manual seedling picking is costly, inefficient, and labor-intensive. Existing vegetable transplanters require multiple people to work simultaneously, which wastes time and a lot of labor. Therefore, it is of great significance to develop a seedling picking device for vegetable transplanters with a high degree of mechanization and automation. Summary of the Invention

[0048] This application provides a continuous ejection device, the working principle of which is as follows: A drive mechanism is connected to a cam transmission mechanism. When the drive mechanism rotates, it drives a portion of the cam transmission mechanism to rotate. A chain transmission mechanism, which is arranged around the cam transmission mechanism and whose two ends are connected to the two ends of the cam transmission mechanism, means that when a portion of the cam transmission mechanism rotates, the chain transmission mechanism connected to it also rotates, causing the chain transmission mechanism to circulate around the cam in the cam transmission mechanism. This drives an ejection mechanism, evenly arranged on the chain transmission mechanism, to circulate around the cam. The ejection mechanism is also movably connected to the cam surface, allowing it to move along the cam surface according to changes in the cam surface. The direction is adjusted accordingly; when the ejector mechanism moves to the upper end of the cam protrusion, and there is still a certain distance from the protrusion, the ejector mechanism begins to enter the seedling tray conveying mechanism. At this time, it begins to eject the seedlings in the seedling tray conveying mechanism. As the ejector mechanism continues to move downward, it will drive some parts in the seedling tray conveying mechanism to move downward until the ejector mechanism moves to the position corresponding to the protrusion. At this time, the ejector mechanism will move to the deepest part of the seedling tray conveying mechanism, and the seedlings in the seedling tray conveying mechanism will be completely ejected. At the same time, the previous ejector mechanism has just entered the seedling tray conveying mechanism and then moves downward. The current ejector mechanism will gradually retract from the seedling tray conveying mechanism until it separates from the seedling tray conveying mechanism. The previous ejector mechanism gradually moves to the position corresponding to the protrusion. This cycle is repeated to continuously eject the seedlings in the seedling tray conveying mechanism.

[0049] The continuous ejection device provided in this application has the following advantages compared with the prior art: the rotation of the cam transmission mechanism drives the rotation of the chain transmission mechanism, thereby driving the ejection mechanism, which is evenly arranged on the chain transmission mechanism, to rotate around the cam, thus enabling the ejection mechanism to continuously eject seedlings from the seedling tray conveying mechanism; the cam transmission mechanism is driven to rotate by the drive mechanism, thereby realizing the automated operation of the ejection mechanism, enabling the device to automatically pick up seedlings.

[0073] To better understand the above-mentioned objectives, features, and advantages of this application, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0074] Many specific details are set forth in the following description in order to provide a full understanding of this application. However, this application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of this application is not limited to the specific embodiments disclosed below.

[0075] The following reference Figures 1 to 12 This application describes a continuous ejection device and a potted seedling transplanter according to some embodiments.

[0076] Example 1

[0077] A continuous ejection device includes a housing 1, a cam transmission mechanism 2, a chain transmission mechanism 3, an ejection mechanism 4, a seedling tray conveying mechanism 5, and a drive mechanism 6. The cam transmission mechanism 2 includes a cam 21, is disposed within the housing 1, and its two ends are rotatably connected to the housing 1. The chain transmission mechanism 3 is arranged around the cam transmission mechanism 2, and its two ends are drively connected to the two ends of the cam transmission mechanism 2. The ejection mechanisms 4 are evenly arranged on the chain transmission mechanism 3 and are rotatably connected to the chain transmission mechanism 3. The ejection mechanisms 4 are also movably connected to the surface of the cam 21. The seedling tray conveying mechanism 5 is disposed on one side of the housing 1, facing the protrusion of the cam 21. The drive mechanism 6 is disposed on one side of the housing 1 and is connected to the cam transmission mechanism 2.

[0078] According to a continuous ejection device of this embodiment, a drive mechanism 6 is connected to a cam transmission mechanism 2. When the drive mechanism 6 rotates, it drives some components in the cam transmission mechanism 2 to rotate. A chain transmission mechanism 3, which is arranged around the cam transmission mechanism 2 and whose two ends are connected to the two ends of the cam transmission mechanism 2, means that when some components in the cam transmission mechanism 2 rotate, the chain transmission mechanism 3, which is connected to it, also rotates, causing the chain transmission mechanism 3 to rotate around the cam 21 in the cam transmission mechanism 2. This drives the ejection mechanism 4, which is uniformly arranged on the chain transmission mechanism 3, to circulate around the cam 21. The ejection mechanism 4 is also movably connected to the surface of the cam 21. Through this movable connection, the ejection mechanism 4 moves along the surface of the cam 21, thus adjusting its position according to changes in the surface of the cam 21. Adjustment; when the ejector mechanism 4 moves to the upper end of the protrusion of the cam 21, and there is still a certain distance from the position of the protrusion of the cam 21, the ejector mechanism 4 begins to enter the seedling tray conveying mechanism 5. At this time, it begins to eject the seedlings in the seedling tray conveying mechanism 5. As the ejector mechanism 4 continues to move downward, it will drive some parts in the seedling tray conveying mechanism 5 to move downward until the ejector mechanism 4 moves to the position corresponding to the protrusion 21. At this time, the ejector mechanism 4 will move to the deepest part of the seedling tray conveying mechanism 5, and the seedlings in the seedling tray conveying mechanism 5 will be completely ejected. At the same time, the previous ejector mechanism 4 has just entered the seedling tray conveying mechanism 5 and then moves downward. The current ejector mechanism 4 will gradually retract from the seedling tray conveying mechanism 5 until it separates from the seedling tray conveying mechanism 5. The previous ejector mechanism 4 gradually moves to the position corresponding to the protrusion 21. This cycle is repeated to continuously eject the seedlings in the seedling tray conveying mechanism 5.

[0079] It should be noted that the cam 21 has two opposing flat surfaces 211 and a surrounding surface 212 disposed between the two flat surfaces 211; the protrusion of the cam 21 is located on the surrounding surface 212, and the cam 21 also includes a surrounding groove 213, two surrounding slides 214, and three mounting holes 215; wherein, the surrounding groove 213 is disposed around the surrounding surface 212, and the surrounding groove 213 has the same shape as the surrounding surface 212; the two surrounding slides 214 are respectively disposed on two opposing inner sidewalls of the surrounding groove 213, and the two surrounding slides 214 are opposite to each other; the two surrounding slides 214 have the same shape as the surrounding surface 212; both surrounding slides 214 are slidably connected to the ejector mechanism 4; the three mounting holes 215 are disposed through the flat surface 211, and the three mounting holes 215 are respectively located at the protrusion and two ends of the flat surface 211.

[0080] Furthermore, when the cam transmission mechanism 2 drives the chain transmission mechanism 3, the ejector mechanism 4 located on the chain transmission mechanism 3 rotates around the surrounding groove 213 on the surrounding surface 212 of the cam 21, and the components in the ejector mechanism 4 are located in the two surrounding slide grooves 214 on the inner sidewall of the surrounding groove 213, and are slidably connected with the two surrounding slide grooves 214; the chain transmission mechanism 3 drives the ejector mechanism 4 to rotate cyclically around the surrounding surface 212 of the cam 21; since the trajectory of the surrounding slide grooves 214 is the same as the trajectory of the surrounding surface 212 of the cam 21, the trajectory of the surrounding surface 212 is used to set... The design, during rotation, utilizes the interaction between the surrounding slide groove 214 and the chain drive mechanism 3 to adjust the angle of the ejector mechanism 4. This ensures that when the ejector mechanism 4 is positioned between the upper and lower ends of the cam 21 protrusion, it remains perpendicular to the seedling tray conveying mechanism 5. When the ejector mechanism 4 is positioned a certain distance above the cam 21 protrusion, it begins to enter the seedling tray conveying mechanism 5. As the chain drive mechanism 3 carries the ejector mechanism 4 downwards, the ejector mechanism 4 drives some components of the seedling tray conveying mechanism 5 downwards as well, thus ejecting... As mechanism 4 gradually penetrates deeper into the seedling tray conveying mechanism 5, it gradually pushes the seedlings out of the seedling tray conveying mechanism 5. As the ejecting mechanism 4 continues to move downwards, it will drive some components of the seedling tray conveying mechanism 5 downwards until it reaches the position of the cam 21 (that is, the extreme position of cam 21, the position closest to the seedling tray conveying mechanism 5). At this point, the ejecting mechanism 4 will have reached the deepest point of the seedling tray conveying mechanism 5, and the seedling corresponding to the current ejecting mechanism 4 will be completely ejected. Meanwhile, the seedlings located above the current ejecting mechanism 4... One ejector mechanism 4 (that is, an ejector mechanism 4 that follows the current ejector mechanism 4 and is located above the current ejector mechanism 4) begins to enter the seedling tray conveying mechanism 5 and then moves downward. The current ejector mechanism 4 continues to drive the components in the seedling tray conveying mechanism 5 to move downward. At this time, the current ejector mechanism 4 will gradually retract from the seedling tray conveying mechanism 5 until it separates from the seedling tray conveying mechanism 5. However, the previous ejector mechanism 4 repeats the movement of the current ejector mechanism 4, and the seedlings corresponding to the previous ejector mechanism 4 in the seedling tray conveying mechanism 5 will be completely ejected, thereby realizing the continuous ejection of seedlings.

[0081] It should be noted that the cam transmission mechanism 2 also includes a rotating shaft 22 and a sprocket 23; wherein, the rotating shaft 22 is disposed in the mounting hole 215, and a rotating shaft 22 is rotatably connected in each mounting hole 215, and one end of any rotating shaft 22 passes through the housing 1 and is connected to the drive mechanism 6; the sprocket 23 is disposed at both ends of the rotating shaft 22, and a sprocket 23 is respectively disposed at both ends of each rotating shaft 22; the sprocket 23 is connected to the chain transmission mechanism 3 for transmission; both ends of each rotating shaft 22 extend from the sprocket 23 to the housing 1, and both ends of each rotating shaft 22 are rotatably connected to the housing 1.

[0082] Furthermore, rotating shafts 22 are disposed in mounting holes 215, with one rotating shaft 22 rotatably connected to each mounting hole 215, so that rotating shafts 22 are disposed in all three mounting holes 215. One end of any rotating shaft 22 passes through the housing 1 and is connected to the drive mechanism 6, indicating that the drive mechanism can drive the rotating shaft 22 connected to it to rotate in the mounting hole 215. Sprockets 23 are disposed at both ends of the rotating shafts 22, with one sprocket 23 at each end of each rotating shaft 22. This means that the drive mechanism 6 drives the rotating shaft 22 connected to it to rotate, thereby driving the sprockets 23 at both ends of the drive shaft 22 to rotate. Since all six sprockets 23 are connected to the chain drive mechanism 3, the rotation of the rotating shaft 22 is achieved. The connection is as follows: the three mounting holes 215 are located at the protrusion and two ends of the flat surface 211, respectively. This means that the three rotating shafts 22 are arranged in a triangular pattern and are similar in shape to the cam 21. As a result, the chain drive mechanism 3, which is set on three pairs of oppositely arranged sprockets 23, is similar in shape to the cam 21. Thus, when the sprockets 23 at both ends of one of the drive shafts 22 rotate, the chain drive mechanism 3 is driven to rotate. Through the three pairs of oppositely arranged sprockets 23, the chain drive mechanism 3 rotates cyclically along a trajectory similar in shape to the cam, thereby driving the ejector mechanism 4 set on the chain drive mechanism 3 to rotate cyclically along a trajectory similar in shape to the cam 21.

[0083] It should be noted that the chain drive mechanism 3 includes two chains 31 and multiple connecting rods 32; wherein, the two chains 31 are respectively disposed on the sprockets 23 on both sides of the cam 21, and the chains 31 on the same side of the cam 21 are connected to each sprocket 23 in a drive connection; the chains 31 include multiple nodes 311, and the distance between any two adjacent nodes 311 is equal; the multiple connecting rods 32 are disposed between the two chains 31, and the two ends of the connecting rods 32 are respectively connected to two opposite nodes 311 of the two chains 31, and the distance between any two adjacent connecting rods 32 is equal; the connecting rods 32 are rotatably connected to the ejection mechanism 4.

[0084] Furthermore, two chains 31 are respectively disposed on both sides of the cam 21 and are respectively connected to three sprockets 23 on both sides of the cam 21. The two chains 31 are respectively wrapped around the three sprockets 23 arranged in a triangle on both sides of the boss 21. When one pair of sprockets 23 rotates at the same time, it drives the two chains 31 to move, thereby causing the two chains 31 to rotate cyclically around the three pairs of sprockets 23 through the other two pairs of sprockets 23. The chain 31 includes multiple nodes 311, and the distance between any two adjacent nodes 311 is equal. Multiple connecting rods 32 are disposed between the two chains 31. The two ends of the connecting rods 32 are respectively connected to two opposite nodes 311 of the two chains 31. The distance between any two adjacent connecting rods 32 is equal. The connecting rods 32 are used to install the ejector mechanism 4, thereby driving the ejector mechanism 4 to rotate cyclically around the surrounding surface 212 of the cam 21 by moving the connecting rods 32 around the surrounding groove 213 in the surrounding surface 212 of the cam 21.

[0085] It should be noted that the ejection mechanism 4 includes a first connecting plate 41, two pulleys 42, two cross roller assemblies 43, a second connecting plate 44, and an ejector rod assembly 45; wherein, the first connecting plate 41 is rotatably connected to the connecting rod 32; the two pulleys 42 are respectively disposed on both sides of one end of the first connecting plate 41, and the two pulleys 42 are respectively slidably disposed in two opposite surrounding grooves 214; the two cross roller assemblies 43 are symmetrically disposed at both ends of the side of the first connecting plate 41 away from the pulleys 42 with the center of the first connecting plate 41 as the axis; the second connecting plate 44 is disposed on the side of the cross roller assemblies 43 away from the first connecting plate 41, and the second connecting plate 44 is connected to the two cross roller assemblies 43; the ejector rod assembly 45 is disposed at the end of the second connecting plate 44 away from the cross roller assemblies 43.

[0086] Furthermore, since the first connecting plate 41 is rotatably connected to the connecting rod 32, the connecting rod 32 rotates around the cam 21, causing the first connecting plate 32 to rotate around the cam 21, thereby realizing that the ejector mechanism 4 moves along with the connecting rod 32 rotating around the cam 21. The two pulleys 42 are located on both sides of one end of the first connecting plate 41 and are slidably disposed in two opposing surrounding grooves 214. This allows the pulleys 42 to slide along the trajectory of the surrounding grooves 214. During the sliding process, since the first connecting plate 41 and the pulleys 42 are rotatably connected, the first connecting plate 41 can rotate around the pulleys 42, and thus, as the trajectory of the surrounding grooves 214 changes, the angle of the first connecting plate 41 also changes. Furthermore, because the two crossed roller assemblies 43 are symmetrically arranged at both ends of the first connecting plate 41 away from the pulley 42, with the center of the first connecting plate 41 as the axis; the second connecting plate 44 is arranged on the side of the crossed roller assembly 43 away from the first connecting plate 41, and the second connecting plate 44 is connected to the two crossed roller assemblies 43; the push rod assembly 45 is arranged at the end of the second connecting plate 44 away from the crossed roller assembly 43, and the angle of the push rod assembly 45 in the ejection mechanism 4 can be controlled by the angle change of the first connecting plate 4, so that when the push rod assembly 45 is located at a certain distance from the upper end of the cam 21 protrusion (before entering the seedling tray conveying mechanism 5) to a certain distance from the lower end of the protrusion (after leaving the seedling tray conveying mechanism 5), the push rod assembly 45 always maintains contact with the seedling tray conveying mechanism 5. The feeding mechanism 5 is vertical; when the push rod assembly 45 begins to enter the seedling tray conveying mechanism 5, it begins to push the seedlings out of the seedling tray conveying mechanism 5. As the current push rod assembly 45 continues to move downward, it will drive some parts of the seedling tray conveying mechanism 5 downward until the current push rod assembly 45 moves to the position corresponding to the protrusion 21. At this time, the current push rod assembly 45 will move to the deepest part of the seedling tray conveying mechanism 5, and the seedlings in the seedling tray conveying mechanism 5 will be completely pushed out. At the same time, the previous push rod assembly 45 (that is, the one that follows the current ejection mechanism 4 and is located above the current ejection mechanism 4) has just entered the seedling tray conveying mechanism 5, but after moving downward, the current push rod assembly 45 located at the protrusion of cam 21... The front push rod assembly 45 will gradually retract from the seedling tray conveying mechanism 5 until it separates from the seedling tray conveying mechanism 5. The previous push rod assembly 45 will gradually move to the position corresponding to the protrusion 21. At this time, the vertical distance between the two push rod assemblies 45 will gradually increase. By setting the cross roller assembly 43 on the first connecting plate 41 and the second connecting plate 44, when the two push rod assemblies 45 move downward, the vertical distance between the two push rod assemblies 45 gradually increases. The seedling tray conveying mechanism 5 will give the push rod assembly 45 a squeezing force. The push rod assembly 45 will drive the cross roller assembly 43 to slide relative to each other, so as to control the vertical distance between the push rod assembly 45 located at the protrusion position of cam 21 and its previous push rod assembly 45 to remain unchanged during their simultaneous downward movement.

[0087] It should be noted that the first connecting plate 41 includes an L-shaped plate 411, a rotating hole 412, a stepped plate 413, and two rotating rods 414; wherein, the L-shaped plate 411 has a horizontal plate 4111 and a vertical plate 4112 connected to the horizontal plate 4111, and the side of the horizontal plate 4111 near the vertical plate 4112 is connected to the cross roller assembly 43; the rotating hole 412 is located on the side of the horizontal plate 4111 away from the vertical plate 4112, and the first connecting plate 41 is rotatably connected to the connecting rod 32 through the rotating hole 412; the stepped plate 413 is located on the side of the horizontal plate 4111 away from the vertical plate 4112; the two rotating rods 414 are respectively located at both ends of the side of the stepped plate 413 away from the horizontal plate 4111, and the two rotating rods 414 are respectively rotatably connected to the pulley 42.

[0088] Furthermore, the rotation hole 412 enables the first connecting plate 41 to rotate and connect the connecting rod 32. When the connecting rod 32 moves, it drives the first connecting plate 41 to move through the rotation hole 412, thereby driving the entire ejection mechanism 4 to move. The step plate 413 is set on the side of the horizontal plate 4111 away from the vertical plate 4112. Two rotating rods 414 are respectively set at both ends of the step plate 413 on the side away from the horizontal plate 4111. The two rotating rods 414 are rotatably connected to the pulley 42. When the push rod assembly 45 is located at a distance from the upper end of the cam 21 protrusion (the position in the cam 21 closest to the seedling tray conveying mechanism 5) to a distance from the lower end of the protrusion (after leaving the seedling tray conveying mechanism 5), due to the structural design of the circumferential groove 214 on the cam 21, the angle of the step plate 413 can change with the trajectory of the circumferential groove 214. Thus, the angle of the first connecting plate 4 can be controlled by the step plate 413, thereby controlling the angle of the push rod assembly 45 in the ejection mechanism 4, so that the push rod assembly 45 remains perpendicular to the seedling tray conveying mechanism 5.

[0089] It should be noted that the cross roller assembly 43 includes a first roller slider 431, a second roller slider 432, a mounting stud 433, and a return torsion spring 434; wherein, the first roller slider 431 is disposed near the vertical plate 4112; the second roller slider 432 is disposed on the side of the first roller slider 431 away from the L-shaped plate 411, and the second roller slider 432 is slidably engaged with the first roller slider 431; the mounting stud 433 is disposed on the side of the first roller slider 431 near the center of the horizontal plate 4111, one end of the mounting stud 433 is connected to the horizontal plate 4111, and the other end is fitted with a nut; the end of the mounting stud 433 away from the horizontal plate 4111 is suspended above the top of the second connecting plate 44; the return torsion spring 434 is arranged around the mounting stud 433, one end of the return torsion spring 434 is in contact with the vertical plate 4112, and the other end is in contact with the inner sidewall of the second connecting plate 44.

[0090] Furthermore, the sliding engagement between the first roller slider 431 and the second roller slider 432 indicates that the first roller slider 431 and the second roller slider 432 are allowed to move relative to each other within a certain range. When the vertical distance between the two push rod assemblies 45 gradually increases from the initial distance, due to the presence of the vertical plate 4112 in the L-shaped plate 411, the second roller slider 432 cannot slide towards the end of the vertical plate 4112, but can only slide away from the vertical plate 4112. Therefore, the seedling tray conveying mechanism 5 applies a squeezing force to the push rod assembly 45 away from the vertical plate 4112, causing the first connecting plate 41 and the second connecting plate 44 to slide relative to each other in the vertical direction. One end of the mounting stud 433 is connected to the horizontal plate 4111, and the other end is equipped with a nut. The mounting stud 433 is suspended above the second connecting plate 44 at one end away from the horizontal plate 4111. The reset torsion spring 434 is arranged around the mounting stud 433, with one end of the reset torsion spring 434 in contact with the vertical plate 4112 and the other end in contact with the inner wall of the second connecting plate 44. When the first connecting plate 41 and the second connecting plate 44 slide relative to each other, the inner wall of the second connecting plate 44 will squeeze the reset torsion spring 434, thus giving the reset torsion spring 434 a squeezing force. When the two push rod assemblies 45 move to below the protrusion of the cam 21, the vertical distance between the two push rod assemblies 45 gradually decreases until it returns to the initial distance. At this time, the squeezing force of the reset torsion spring 434 is released, and the first roller slider 431 and the second roller slider 432 are reset.

[0091] It should be noted that the push rod assembly 45 includes two pull rods 451 and multiple push rods 452; wherein, the two pull rods 451 are respectively disposed at both ends of the second connecting plate 44 away from the second roller slider 432; the multiple push rods 452 are evenly arranged on the side of the second connecting plate 44 away from the second roller slider 432, and the multiple push rods 452 are disposed between the two pull rods 451.

[0092] Furthermore, the two pull rods 451 of the ejection mechanism 45 are used to pull down some parts of the seedling tray conveying mechanism 5, while the multiple push rods 452 are used to eject the seedlings in the seedling tray conveying mechanism 5. When the push rod assembly 45 is located at a distance from the upper end of the cam 21 protrusion (the position in the cam 21 closest to the seedling tray conveying mechanism 5) to a distance from the lower end of the protrusion (after leaving the seedling tray conveying mechanism 5), due to the structural design of the surrounding slide groove 214 on the cam 21, the angle of the step plate 413 can change with the trajectory of the surrounding slide groove 214. Thus, the angle change of the first connecting plate 4 can be controlled by the step plate 413, thereby controlling the angle of the two pull rods 451 and the multiple push rods 452 in the push rod assembly 45 of the ejection mechanism 4, so that the two pull rods 451 and the multiple push rods 452 remain perpendicular to the seedling tray conveying mechanism 5.

[0093] It should be noted that the seedling tray conveying mechanism 5 includes a seedling tray track 51, a potted seedling tray 52, and a pressure plate component 53; wherein, the seedling tray track 51 is located on one side of the housing 1, and slide rails 511 are provided on both sides of the seedling tray track 51 opposite to each other; vertical pull grooves 512 are provided on both sides of the seedling tray track 51 facing the protrusion of the cam 21, and the vertical pull grooves 512 on the same side are connected to the slide rails 511; a plurality of evenly arranged vertical top grooves 513 are provided between the two vertical pull grooves 512. The potted seedling tray 52 is set in the seedling tray track 51. Both ends of the potted seedling tray 52 are slidably connected to the slide rails 511 on both sides of the seedling tray track 51. Each end of the potted seedling tray 52 is provided with a row of evenly arranged pull holes 522. The potted seedling tray 52 is provided with multiple arrayed seedling holes 521, and the seedling holes 521 are all located between two rows of pull holes 522. The pressing plate component 53 is set on one side of the potted seedling tray 52. ​​The pressing plate component 53 contacts and presses the potted seedling tray 52.

[0094] Furthermore, the seedling tray track 51 is securely mounted on one side of the housing 1, providing a fixed running path for the potted seedling tray 52; the slide rails 511 on both sides of the seedling tray track 51 provide sliding connection tracks for the potted seedling tray 52, ensuring stable vertical movement of the potted seedling tray 52; the vertical pull grooves 512 on both sides of the seedling tray track 51 facing the protrusion of the cam 21 are connected to the slide rails 511 on the same side; the pull rod 451 in the push rod assembly 45 enters vertically into the pull hole 522 in the potted seedling tray 52 through the vertical pull groove 512, and moves downward by the pull rod 451, driving the potted seedling tray 52 to move downward; at the same time, the push rod 452 in the push rod assembly 45 enters vertically into the seedling hole 52 in the potted seedling tray 52 through the vertical push groove 513. 1. When the pull rod 451 and the push rod 452 are a certain distance from the upper end of the cam 21 protrusion, the pull rod 451 begins to vertically enter the pull hole 522 in the seedling tray 52 through the vertical pull groove 512, and at the same level, the push rod 452 begins to vertically enter the seedling hole 521 in the seedling tray 52 through the vertical push groove 513. As the chain drive mechanism 3 moves downward with the ejection mechanism 4, the pull rod 451 pulls the seedling tray 52 to slide downward in the slide rails 511 on both sides of the seedling tray track 51. The depth of the push rod 452 entering the seedling hole 521 gradually increases, gradually pushing the seedling out of the seedling hole 521. As the chain drive mechanism 3 continues to rotate, the pull rod 451 pulls the seedling tray 52 to continue to slide downward in the slide rails 511 on both sides of the seedling tray track 51. Until the pull rod 451 and the push rod 452 move to the protruding position of the cam 21 (that is, the extreme position of the cam 21, the position of the cam 21 closest to the seedling tray conveying mechanism 5), the push rod 452 will move to the deepest part of the seedling hole 521 in the seedling tray 52 of the pot body, and the seedling in the seedling hole 521 corresponding to the current push rod 452 will be completely pushed out. The pull rod 451 and the push rod 452 of the previous push mechanism 4 (that is, the push mechanism 4 that follows the current push mechanism 4 and is located above the current push mechanism 4) will start to enter the previous set of pull holes 522 and seedling holes 521 (the row above the current seedling hole 521 and pull holes 522) respectively; chain The transmission mechanism 3 then moves, and the pull rod 451 in the current ejection mechanism 4 continues to drive the seedling tray 52 in the pot to slide downward in the slide rails 511 on both sides of the seedling tray track 51. At this time, the pull rod 451 and the push rod 452 in the current ejection mechanism 4 will gradually retract from the corresponding pull hole 522 and seedling hole 521 in the seedling tray 52 until they are separated from the seedling tray 52. ​​However, the pull rod 451 and the push rod 452 of the previous ejection mechanism 4 (that is, the ejection mechanism 4 that follows the current ejection mechanism 4 and is located above the current ejection mechanism 4) repeat the movement of the pull rod 451 and the push rod 452 in the current ejection mechanism 4, so that the seedlings in the seedling tray 52 corresponding to the previous ejection mechanism 4 will be completely ejected, thereby realizing the continuous ejection of the seedlings.Since the seedling tray 52 has its own weight, a pressure plate 53 is positioned on one side of the seedling tray 52. ​​The pressure plate 53 contacts and presses against the seedling tray 52, thus applying pressure to the seedling tray 52 and causing it to be pressed between the slide rails 511. This prevents the seedling tray 52 from moving due to its own weight.

[0095] According to a continuous ejection device of this embodiment, its operation process is as follows:

[0096] The drive mechanism 6 moves, causing the rotating shaft 22 connected to it to rotate in the cam 21, thereby causing the sprockets 23 at both ends of the rotating shaft 22 connected to the drive mechanism 6 to rotate simultaneously. As the sprockets 23 rotate, they drive the two chains 31 to move, thus causing the two chains 31 to rotate cyclically around the three pairs of sprockets 23 through the other two pairs of sprockets 23. This causes the multiple connecting rods 32, which are evenly arranged between the two chains 23, to rotate cyclically around the surrounding grooves 213 on the surrounding surface 212 of the cam 21. Since the ejector assembly 4 is rotatably connected to the connecting rods 32 through the rotating hole 412, the movement of the connecting rods 32 causes the ejector mechanism 4 to rotate cyclically around the surrounding grooves 213 on the surrounding surface 212 of the cam 21. The pulleys 4 in the ejector mechanism 4... 2. Slide along the trajectory of the surrounding groove 214; since the trajectory of the surrounding groove 214 is the same as the trajectory of the surrounding surface 212 of the cam 21, through the trajectory design of the surrounding surface 212, while rotating, it is slidably connected in the surrounding groove 214 through the pulley 42, and rotatedly connected to the connecting rod 32 through the rotating hole 412, thereby achieving the purpose of controlling the angle of the pull rod 451 and the push rod 452 in the push rod assembly 45, so that when the pull rod 451 and the push rod 452 are located at the upper end of the cam 21 protrusion (before the pull rod 451 and the push rod 452 enter the seedling tray 52) to the lower end of the protrusion (after the pull rod 451 and the push rod 452 leave the seedling tray 52), the pull rod 451 and the push rod 452 always remain in contact with the seedling tray 52. 2. Vertical: When the pull rod 451 and the push rod 452 are a certain distance from the upper end of the cam 21 protrusion, the pull rod 451 begins to vertically enter the pull hole 522 in the seedling tray 52 through the vertical pull groove 512, and at the same level, the push rod 452 begins to vertically enter the seedling hole 521 in the seedling tray 52 through the vertical push groove 513; as the chain drive mechanism 3 moves downward with the ejection mechanism 4, the pull rod 451 pulls the seedling tray 52 downward in the slide rails 511 on both sides of the seedling tray track 51; the depth of the push rod 452 entering the seedling hole 521 gradually increases, gradually pushing the seedling out of the seedling hole 521. As the chain drive mechanism 3 continues to rotate, the pull rod 451 pulls the seedling tray 52 downward in the slide rails 511 on both sides of the seedling tray track 51. Slide until the pull rod 451 and the push rod 452 move to the protruding position of the cam 21 (that is, the extreme position of the cam 21, the position of the cam 21 closest to the seedling tray conveying mechanism 5). At this time, the push rod 452 will move to the deepest part of the seedling hole 521 in the seedling tray 52. ​​The seedling in the seedling hole 521 corresponding to the current push rod 452 will be completely pushed out. The pull rod 451 and the push rod 452 of the previous push mechanism 4 (that is, the push mechanism 4 that follows the current push mechanism 4 and is located above the current push mechanism 4) will start to enter the previous set of pull holes 522 and seedling holes 521 (the row above the current seedling hole 521 and pull holes 522) respectively.The chain drive mechanism 3 then moves, and the pull rod 451 in the current ejection mechanism 4 continues to drive the seedling tray 52 in the pot to slide downward in the slide rails 511 on both sides of the seedling tray track 51. At this time, the pull rod 451 and the push rod 452 in the current ejection mechanism 4 will gradually retract from the corresponding pull holes 522 and seedling holes 521 in the seedling tray 52 until they separate from the seedling tray 52. ​​However, the pull rod 451 of the previous ejection mechanism 4 (that is, the ejection mechanism 4 that follows the current ejection mechanism 4 and is located above the current ejection mechanism 4) will continue to move. The push rod 452 repeats the movement of the pull rod 451 and push rod 452 in the current ejection mechanism 4. At this time, the vertical distance between the two push rod assemblies 45 gradually increases. However, by sliding the cross roller assembly 43 up and down, the vertical distance between the pull rods 451 in the two push rod assemblies 45 is adjusted, ensuring that the vertical distance between the pull rods 451 in the two push rod assemblies 45 remains constant and is the same as the distance between the upper and lower seedling holes 521 in the seedling tray 52; thus, the seedlings in the seedling holes 521 of the seedling tray 52 are continuously ejected.

[0097] According to the continuous ejection device of this embodiment, the beneficial effects are as follows:

[0098] The rotation of the cam transmission mechanism drives the rotation of the chain transmission mechanism, which in turn drives the ejector mechanism, which is evenly arranged on the chain transmission mechanism, to rotate around the cam. This allows the ejector mechanism to continuously eject seedlings from the seedling tray conveyor mechanism. The cam transmission mechanism is driven to rotate by the drive mechanism, thereby automating the ejector mechanism. This enables the device to automatically pick up seedlings, significantly improving the seedling picking efficiency compared to traditional manual seedling picking.
