[0004] The aforementioned patent addresses the problems of existing seedling transplanting devices for Salvia miltiorrhiza cultivation being less user-friendly, causing significant fatigue for operators over long periods, and requiring separate watering after transplanting, which is time-consuming, labor-intensive, and affects work efficiency. However, when transplanting Salvia miltiorrhiza, it is necessary to position the plant. Mechanical transplanting without proper positioning may damage the plant during transplanting, leading to its death and causing property loss. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a seedling transplanting device for Salvia miltiorrhiza cultivation, which solves the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a seedling transplanting device for Salvia miltiorrhiza cultivation, comprising a base plate, rollers rotatably mounted on the bottom of the base plate, and a conveying device provided on the top of the base plate. The conveying device includes: a baffle plate, a belt, and rollers. The baffle plate is fixedly mounted on the top of the base plate, and the rollers are rotatably mounted between the baffle plates. The belt is connected via the rollers for transmission. A rotary motor is fixedly mounted on the surface of the baffle plate, and the output end of the rotary motor rotatably penetrates the inner and outer walls of the baffle plate. The output end of the rotary motor is fixedly mounted on the surface of the rotating shaft. A seat is fixedly mounted on the top of the base plate, a control lever is provided on the top of the base plate, and a positioning device, a seedling picking device, and a protective device are provided on the top of the base plate.

[0007] The positioning device includes: an electric push rod, a push plate, a spring, a clamping plate, a support frame, a through rod, a fixing block, a fixing plate, and a positioning arc plate. The electric push rod is fixedly installed on the surface of the baffle plate, and its output end slides through the inner and outer walls of the baffle plate. The push plate is fixedly installed on the side of the electric push rod near the belt. The spring is fixedly installed on the side of the push plate away from the electric push rod. The clamping plate is connected to the push plate through the spring. The support frame is fixedly installed on the top of the base plate. The through rod is fixedly inserted through the inner and outer walls of the support frame. The fixing block is fixedly installed on the side of the support frame near the seat. The fixing plates are all slidably installed on the sides of the fixing block and the through rod that are close to each other. The positioning arc plates are all fixedly installed on the surface of the fixing plate. When the positioning arc plate moves, it will cause the fixing plate to move to the top. After the potted plant completely passes over the positioning arc plate, the fixing plate will move to the bottom through the reset spring. The movement of the fixing plate will cause the positioning arc plate to move to the bottom.

[0008] According to the above technical solution, a first spring is provided between the fixing plates, and the push plate contacts the clamping plate, so that the fixing plate is reset by the first spring.

[0009] According to the above technical solution, the seedling taking device includes: a slide rail, a sliding block, a hollow cylinder, a sleeve, and a seedling taking clamp. The slide rail is fixedly installed on the side of the support frame away from the fixed block. The sliding block is slidably installed on the surface of the slide rail. A driving device is provided inside the sliding block. The hollow cylinder is fixedly installed through the inner and outer walls of the sliding block. The sleeve is slidably installed on the inner wall of the hollow cylinder. The seedling taking clamp is fixedly installed at the bottom of the sleeve. When the sleeve moves to the bottom, it will drive the seedling taking clamp to the bottom. When the seedling taking clamp moves to the bottom, it will insert into the inside of the Salvia miltiorrhiza potted plant. Then, the sleeve moves to the top, and when the sleeve moves to the top, it will drive the seedling taking clamp to the top.

[0010] According to the above technical solution, the seedling extraction device further includes: a rotating rod, an arc rod, a protective plate, and a connecting rod. The rotating rod is rotatably mounted on the inner wall of the sliding block. The arc rod is fixedly mounted on the circumferential surface of the rotating rod. A sliding groove is formed inside the arc surface of the arc rod. The protective plate is fixedly mounted on the bottom of the arc rod. One end of the connecting rod is fixedly mounted on the bottom of the sleeve, and the other end of the connecting rod is slidably mounted on the inner wall of the sliding groove. The rotation of the arc rod will drive the protective plate to rotate. After the protective plate rotates, it will move to the bottom of the Salvia miltiorrhiza to prevent it from falling after being extracted. When the sleeve moves to the bottom, the movement of the sleeve will drive the connecting rod to move to the bottom. The movement of the connecting rod to the top will drive the arc rod to rotate, and the rotation of the arc rod will cause the rotating rod to rotate.

[0011] According to the above technical solution, the sliding block is in contact with the through rod, and a torsion spring is provided between the rotating rod and the sliding block. The rotating rod is reset by the torsion spring.

[0012] According to the above technical solution, the protective device includes: a second electric push rod, a friction plate, a telescopic rod, a square tube, a positioning square plate, and a triangular block. The second electric push rod is fixedly installed on the inner wall of the hollow cylinder. The friction plate is fixedly installed on the circumferential surface of the output end of the second electric push rod. The telescopic rod is fixedly installed on the circumferential surface of the output end of the second electric push rod. The square tube is fixedly installed on the circumferential surface of the inner wall of the hollow cylinder. The positioning square plate is fixedly installed on the inner wall of the square tube. The triangular block is slidably installed on the inner wall of the square tube. After the telescopic rod moves, it will contact the triangular block. The movement of the telescopic rod will drive the triangular block to move away from the friction plate. After the friction plate moves, it will no longer contact the triangular block, so that it will not be affected by friction.

[0013] According to the above technical solution, a second spring is provided between the triangular block and the positioning plate, and the telescopic rod contacts the triangular block, so that the triangular block is reset by the second spring.

[0014] According to the above technical solution, the telescopic rod is equipped with a No. 3 spring, the triangular block is in contact with the friction plate, and the No. 3 spring drives the output end of the telescopic rod to reset.

[0015] This invention provides a seedling transplanting device for Salvia miltiorrhiza cultivation. It has the following beneficial effects:

[0016] (1) This invention uses a clamp to move and contact the Salvia miltiorrhiza and push it to position the Salvia miltiorrhiza, which facilitates continuous mechanized operations. It does not require manual operation, has strong stability and high practicality. The fixed plate moves and drives the positioning arc plate to move to the bottom. The positioning arc plate moves to the bottom and inserts into the soil, which loosens the soil around the Salvia miltiorrhiza seedlings, making it easier to transplant them and improving work efficiency.

[0017] (2) In this invention, the sleeve moves to the top, which drives the seedling tweezers to move to the top. The seedling tweezers moving to the top will take the Salvia miltiorrhiza seedlings out of the Salvia miltiorrhiza pot, which makes it quick and easy to take out the Salvia miltiorrhiza in the pot, saving time and improving work efficiency. The rotating rod rotates by the arc rod, so that the device will not affect the seedling tweezers when they are taking seedlings, which improves the practicality of the device, ensures that the seedlings will not fall during transportation and affect the transplanting, and improves the success rate of transplanting.

[0018] (3) The invention increases the contact area between the friction plate and the triangular block after the friction plate deforms, thereby increasing the friction between the friction plate and the triangular block. This reduces the speed at which the seedling clamp moves to the bottom, preventing the soil from loosening during seedling removal and causing the soil around the salvia miltiorrhiza to fall off, thus preventing the salvia miltiorrhiza from dying after transplanting. This improves the survival rate of transplanting. After the friction plate moves, it no longer contacts the triangular block, thus avoiding the influence of friction. This prevents the device from being overloaded and damaged when moving to the top after the salvia miltiorrhiza seedlings are removed, thus improving the protection effect of the device.

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0028] Please see Figures 1-4One embodiment of the present invention is: a seedling transplanting device for Salvia miltiorrhiza cultivation, comprising a base plate 1, rollers 2 rotatably mounted on the bottom of the base plate 1, and a conveying device 3 provided on the top of the base plate 1. The conveying device 3 includes: a baffle plate, a belt, and a roller. The baffle plate is fixedly mounted on the top of the base plate 1, the roller is rotatably mounted between the baffle plates, and the belt is connected via the roller transmission. A rotary motor 4 is fixedly mounted on the surface of the baffle plate, the output end of the rotary motor 4 rotatably penetrates the inner and outer walls of the baffle plate, and the output end of the rotary motor 4 is fixedly mounted on the surface of the rotating shaft. A seat 5 is fixedly mounted on the top of the base plate 1, a control lever 6 is provided on the top of the base plate 1, and a positioning device is provided on the top of the base plate 1. The positioning device includes: an electric push rod 71, a push plate 72, a spring 73, a clamping plate 74, a support frame 75, a through rod 76, a fixing block 77, a fixing plate 78, and a positioning arc plate 79. The electric push rod 71 is fixedly mounted on the top of the base plate 1. Installed on the surface of the baffle plate, the output end of the electric push rod 71 slides through the inner and outer walls of the baffle plate. The push plate 72 is fixedly installed on the side of the electric push rod 71 near the belt. The spring piece 73 is fixedly installed on the side of the push plate 72 away from the electric push rod 71. The clamping plate 74 is connected to the push plate 72 through the spring piece 73. The support frame 75 is fixedly installed on the top of the base plate 1, which facilitates continuous mechanized operation without manual operation. It has strong stability and high practicality. The through rod 76 is fixedly installed through the inner and outer walls of the support frame 75. The fixing block 77 is fixedly installed on the side of the support frame 75 near the seat 5. The fixing plates 78 are all slidably installed on the side of the fixing block 77 and the through rod 76 that are close to each other. The positioning arc plate 79 is fixedly installed on the surface of the fixing plate 78. When the positioning arc plate 79 moves to the bottom, it will insert into the soil and loosen the soil around the Salvia miltiorrhiza seedlings, which will facilitate subsequent transplanting and improve work efficiency.

[0029] A first spring is provided between the fixed plates 78. The push plate 72 contacts the clamping plate 74, and the first spring drives the fixed plate 78 to reset.

[0030] In this embodiment, during operation: The danshen (Salvia miltiorrhiza) is placed on top of the belt. The output of the rotary motor 4 rotates, which in turn drives the rotating shaft and rollers to rotate. This rotation of the rollers drives the belt, which then transports the danshen towards the support frame 75. During the movement of the danshen, the output of the electric push rod 71 moves, causing the push plate 72 to reciprocate. The movement of the push plate 72 causes the spring 73 to move towards the danshen. The movement of the spring 73 then causes the clamping plate 74 to move towards the danshen. The clamping plate 74 contacts and pushes the danshen, positioning it for subsequent continuous mechanized operations. This eliminates the need for manual operation, ensuring high stability and practicality. The danshen moves... When the seedling reaches the bottom of the support frame 75, it will come into contact with the positioning arc plate 79. The seedling will deform into the gap between the positioning arc plates 79 due to the influence of the positioning arc plate 79. The potted plant will then come into contact with the positioning arc plate 79 and push the positioning arc plate 79 to the top. The movement of the positioning arc plate 79 will cause the fixing plate 78 to move to the top. After the potted plant has completely passed the positioning arc plate 79, the fixing plate 78 will move to the bottom through the reset of the first spring. The movement of the fixing plate 78 will cause the positioning arc plate 79 to move to the bottom. The positioning arc plate 79 will then be inserted into the soil and loosen the soil around the seedling, making it easier to transplant and improving work efficiency.

[0031] Please see Figures 1-7 Based on the above embodiments, in another embodiment of the present invention, the top of the base plate 1 is provided with a seedling taking device and a protective device. The seedling taking device includes: a slide rail 81, a sliding block 82, a hollow cylinder 83, a sleeve 84, and a seedling taking clamp 85. The slide rail 81 is fixedly installed on the side of the support frame 75 away from the fixed block 77. The sliding block 82 is slidably installed on the surface of the slide rail 81. A driving device is provided inside the sliding block 82. The hollow cylinder 83 is fixedly inserted through the inner and outer walls of the sliding block 82. The sleeve 84 is slidably installed on the inner wall of the hollow cylinder 83. The seedling taking clamp 85 is fixedly installed at the bottom of the sleeve 84. When the seedling taking clamp 85 moves to the top, it will take the Salvia miltiorrhiza seedlings out of the Salvia miltiorrhiza pot, so that the Salvia miltiorrhiza in the pot can be taken out quickly, which is convenient, fast, saves time, and improves work efficiency.

[0032] The seedling-taking device also includes: a rotating rod 86, an arc rod 88, a protective plate 89, and a connecting rod 810. The rotating rod 86 is rotatably mounted on the inner wall of the sliding block 82. The arc rod 88 is fixedly mounted on the circumferential surface of the rotating rod 86. A sliding groove is provided inside the arc surface of the arc rod 88. The protective plate 89 is fixedly mounted on the bottom of the arc rod 88. One end of the connecting rod 810 is fixedly mounted on the bottom of the sleeve 84, and the other end of the connecting rod 810 is slidably mounted on the inner wall of the sliding groove. This ensures that the device will not affect the seedling-taking clamp 85 when it is taking seedlings, thus improving the practicality of the device, ensuring that the seedlings will not fall during transportation and thus affecting the transplanting, and improving the success rate of transplanting.

[0033] The sliding block 82 contacts the through rod 76, and a torsion spring 87 is provided between the rotating rod 86 and the sliding block 82. The rotating rod 86 is reset by the torsion spring 87.

[0034] The protective device includes: an electric push rod 91, a friction plate 92, a telescopic rod 93, a square tube 94, a positioning square plate 95, and a triangular block 96. The electric push rod 91 is fixedly installed on the inner wall of the hollow cylinder 83. The friction plate 92 is fixedly installed on the circumferential surface of the output end of the electric push rod 91. The telescopic rod 93 is fixedly installed on the circumferential surface of the output end of the electric push rod 91. The square tube 94 is fixedly installed on the circumferential surface of the inner wall of the hollow cylinder 83. The positioning square plate 95 is fixedly installed on the inner wall of the square tube 94. The triangular block 96 is slidably installed on the inner wall of the square tube 94. This reduces the speed of the seedling clamp 85 when it moves to the bottom, preventing it from being quickly inserted into the soil during seedling removal, which could cause the soil around the salvia miltiorrhiza to loosen and fall off, leading to the death of the salvia miltiorrhiza after transplanting. This improves the survival rate of transplanted salvia miltiorrhiza and prevents the device from being overloaded and damaged when moving to the top after the salvia miltiorrhiza seedlings are removed, thus improving the protection effect of the device.

[0035] A second spring 97 is provided between the triangular block 96 and the positioning square plate 95. The telescopic rod 93 contacts the triangular block 96, and the triangular block 96 is reset by the second spring 97.

[0036] The telescopic rod 93 is equipped with a No. 3 spring. The triangular block 96 contacts the friction plate 92, and the No. 3 spring drives the output end of the telescopic rod 93 to reset.

[0037] In this embodiment, during operation: the driving device causes the sliding block 82 to slide on the surface of the slide rail 81. When the sliding block 82 moves towards the Salvia miltiorrhiza, it contacts the through rod 76. After being blocked by the through rod 76, the sliding block 82 stops moving. The movement of the sliding block 82 causes the hollow cylinder 83 to move, and then the sleeve 84 moves to the bottom. This movement of the sleeve 84 to the bottom causes the seedling clamp 85 to move to the bottom, inserting it into the Salvia miltiorrhiza pot. Then, the sleeve 84 moves to the top, causing the seedling clamp 85 to move to the top, removing the Salvia miltiorrhiza seedling from the pot. This allows for quick and easy removal of the Salvia miltiorrhiza from the pot, saving time and effort. To save time and improve work efficiency, the sleeve 84 moves upward, causing the connecting rod 810 to move upward. The connecting rod 810 moves upward, pushing the arc rod 88 to rotate. The rotation of the arc rod 88 causes the protective plate 89 to rotate. After the protective plate 89 rotates, it moves to the bottom of the Salvia miltiorrhiza to prevent it from falling after being taken out. When the sleeve 84 moves downward, the sleeve 84 moves downward, causing the connecting rod 810 to move downward. The connecting rod 810 moves upward, causing the arc rod 88 to rotate. The rotation of the arc rod 88 causes the rotating rod 86 to rotate. This ensures that when the seedling clamp 85 is taking out seedlings, the device will not affect the seedling clamp 85, improving the practicality of the device and ensuring that the seedlings will not fall during transportation, thus improving the success rate of transplanting.

[0038] When the sleeve 84 moves to the bottom, it drives the output end of the electric push rod 91 to move to the bottom. This movement of the output end of the electric push rod 91 to the bottom drives the friction plate 92 to move to the bottom. The friction plate 92 then contacts the triangular block 96, pushing the triangular block 96 towards the outer wall of the hollow cylinder 83. After contacting the triangular block 96, the friction plate 92 deforms, increasing the contact area between them and thus increasing the friction. This reduces the speed of the seedling clamp 85 as it moves to the bottom, preventing... When taking seedlings, rapid insertion into the soil causes soil loosening upon removal, leading to the falling off of the soil attached to the Salvia miltiorrhiza and causing the seedlings to die after transplanting. This improves the survival rate of transplanted seedlings. As the sleeve 84 moves, it drives the telescopic rod 93 to move to the bottom. After moving, the telescopic rod 93 contacts the triangular block 96. The movement of the telescopic rod 93 drives the triangular block 96 to move away from the friction plate 92. After the friction plate 92 moves, it no longer contacts the triangular block 96, thus avoiding the influence of friction. This prevents the device from being overloaded and damaged due to excessive resistance when moving upwards after the Salvia miltiorrhiza seedlings are removed, improving the protection effect of the device.

[0039] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
