[0019] By manually pulling the pull ring by the worker, the sliding column is disengaged from the hollow chuck, and by stretching the spring, the sliding column penetrates through the hollow chuck. Then, by manually turning the pull ring by the worker by 90 degrees, the pull ring is engaged with the limit block. Thus, the transplanting plate body can be quickly disassembled and replaced, enabling the transplanting box to load multiple transplanting plate bodies. Furthermore, the time required to replace the transplanting plate body can be reduced, thereby improving the overall transplanting efficiency. At the same time, different transplanting plate bodies can be replaced according to different types of Chinese herbal medicine seedlings, so as to adapt to different transplanting requirements.

[0020] By manually pressing the push-pull plate downward by the worker, the teeth on the limit frame are disengaged from the conveyor belt, and by manually pushing and pulling the seedling-raising cylinder horizontally by the worker, the distance between multiple seedling-raising cylinders can be adjusted accordingly. Thus, the planting spacing between the Chinese herbal medicine seedlings in multiple seedling-raising cylinders can be adjusted, which can optimize the growth environment of the Chinese herbal medicine seedlings, and further effectively improve the transplanting survival rate, thereby improving the quality and yield of the Chinese herbal medicine.

[0042] Next, the present invention will be further described in detail according to the drawings and embodiments.

[0043] Embodiment

[0044] As Figures 1 to 3As shown in the figure, to solve the problems mentioned in the technical solution, the embodiment of the present application provides a Chinese herbal medicine planting and seedling transplanting board, including a transplanting box 1. On both sides of the bottom of the transplanting box 1, rollers 101 are symmetrically and rotatably connected, and the rollers 101 are configured with drive motors for driving the movement of the transplanting box 1. At the four corners of the top of the transplanting box 1, connecting columns 102 are fixedly connected.

[0045] As Figures 11 to 14 shown, a disassembly and assembly component is provided at the top end of the connecting column 102. The disassembly and assembly component includes a card slot 2 opened at the top end of the connecting column 102. A sliding column 201 is slidably connected inside the card slot 2. A baffle 202 is fixedly connected to the outer surface of the sliding column 201. One end of the sliding column 201 is fixedly connected with a pull ring 203. The pull ring 203 is located outside the connecting column 102. A tension spring 204 is sleeved on the outer surface of the sliding column 201. The two ends of the tension spring 204 are respectively in contact with the baffle 202 and the inner wall of the card slot 2 close to the pull ring 203. On each connecting column 102, limiting blocks 205 are symmetrically and fixedly connected. The side of the limiting block 205 away from the connecting column 102 is located on the movement track of the pull ring 203. When the pull ring 203 is rotated to a vertical state, it can be slidably adapted between every two limiting blocks 205. When the pull ring 203 is rotated to a horizontal state, it can be made to contact the side of the limiting block 205 away from the card slot 2. A hollow clamping block 206 is slidably connected inside the card slot 2. The hollow clamping block 206 is provided with a hole groove. The middle hole groove of the hollow clamping block 206 is adapted to the sliding column 201. Among them, the limiting block 205 can make the sliding column 201 and the hollow clamping block 206 in a separated state, thereby releasing the limiting effect on the hollow clamping block 206.

[0046] As Figures 3 to 6 shown, an automatic feeding mechanism is provided on the top of the transplanting box 1. The automatic feeding mechanism includes a transplanting board body 3. The hollow clamping block 206 is fixedly connected to the four corners of the bottom of the transplanting board body 3. The transplanting board body 3 is in a clamping fit with the card slot 2 through the hollow clamping block 206. A plurality of rectangular grooves 301 are equidistantly opened on the transplanting board body 3. Two transmission rods 302 are symmetrically and rotatably connected in the plurality of rectangular grooves 301. The number of the transmission rods 302 is two. A stepping motor 303 is fixedly connected to the outer wall of one side of the transplanting box 1. The output shaft of the stepping motor 303 is fixedly connected to the transmission rod 302 close to it. A plurality of conveying wheels 304 are equidistantly fixedly connected to each transmission rod 302. Every two conveying wheels 304 are a group. Two groups of conveying wheels 304 are arranged in each rectangular groove 301. A conveyor belt 305 is sleeved on the outer surface of each group of conveying wheels 304. A plurality of notches are equidistantly opened on the conveyor belt 305.

[0047] A plurality of seedling raising cylinders 306 are equidistantly arranged at the bottom of the conveyor belt 305, and circular openings are formed at the bottoms of the inner cavities of the plurality of seedling raising cylinders 306, which are used for the feeding work of Chinese herbal medicine seedlings. A blocking plate 307 is rotatably connected to the bottom of the plurality of seedling raising cylinders 306. Among them, the blocking plate 307 is integrally L-shaped. The longer part of the blocking plate 307 is attached to the outer wall of the bottom of the seedling raising cylinder 306, and the shorter part of the blocking plate 307 is located on the side away from the bottom of the seedling raising cylinder 306. A torsion spring 308 is symmetrically and fixedly connected between the blocking plate 307 and the outer wall of the seedling raising cylinder 306. A rubber pad 309 is fixedly connected to the side of the blocking plate 307 close to the seedling raising cylinder 306, and the surface of the rubber pad 309 is adapted to the inside of the circular opening at the bottom of the inner cavity of the seedling raising cylinder 306. A feeding port 310 is formed in the top of the transplanting box 1 on the side away from the stepping motor 303. A trigger plate 311 is fixedly connected to the top of the transplanting box 1 on the side close to the feeding port 310. The top of the trigger plate 311 is located on the movement track of the shorter part of the blocking plate 307. A first protective cover 312 is symmetrically and fixedly connected inside each rectangular groove 301. The first protective cover 312 is sleeved on the outer surface of the transmission rod 302. The first protective cover 312 covers the conveyor belt 305 and the conveyor wheels 304, and the first protective cover 312 does not contact the conveyor belt 305 and the conveyor wheels 304. The first protective cover 312 can prevent the conveyor belt 305 and the conveyor wheels 304 from damaging Chinese herbal medicine seedlings.

[0048] As Figures 5 to 7 shown, the conveyor belt 305 is provided with an adjusting assembly. The adjusting assembly includes a connecting cylinder 4. The connecting cylinder 4 is symmetrically and fixedly connected to the top of the seedling raising cylinder 306. The upper part of the connecting cylinder 4 is in sliding fit with the surface of the conveyor belt 305. Four sliding grooves 401 are formed in the top of each seedling raising cylinder 306. The four sliding grooves 401 are symmetrically arranged at the four corners of the top of the seedling raising cylinder 306. A limiting frame 402 is slidably connected inside each sliding groove 401. A clamping tooth 403 is fixedly connected to the top of the limiting frame 402. A plurality of convex strips are fixedly connected to the clamping tooth 403, and the convex strips on the clamping tooth 403 are adapted to the concave openings on the conveyor belt 305. The clamping tooth 403 is located inside the connecting cylinder 4. A return spring 404 is fixedly connected between the bottom of the limiting frame 402 and the bottom of the inner cavity of the sliding groove 401. A push-pull plate 405 is fixedly connected to every two limiting frames 402. The push-pull plate 405 is in sliding fit with the sliding groove 401.

[0049] As Figures 8 to 10As shown in the figure, a soil-fixing mechanism is provided on the seedling-raising cylinder 306. The soil-fixing mechanism includes a groove 5, which is opened on the inner wall of the seedling-raising cylinder 306 near the torsion spring 308. Two reciprocating lead screws 501 are symmetrically and rotatably connected inside the groove 5, and the number of the reciprocating lead screws 501 is two. The threads of the two reciprocating lead screws 501 are opposite, and the two reciprocating lead screws 501 are fixedly connected. Extrusion plates 502 are threadedly connected to the outer surfaces of the two reciprocating lead screws 501 through nuts. The extrusion plates 502 are integrally arc-shaped, and the outer arc surfaces of the extrusion plates 502 are slidably connected to the inner wall of the seedling-raising cylinder 306. A second protective cover 503 is fixedly connected to the inner wall of the seedling-raising cylinder 306 near the reciprocating lead screws 501. A limiting groove 504 is opened on one side of the outer arc surface of the extrusion plate 502 near the reciprocating lead screw 501. The two ends of the second protective cover 503 are slidably matched with the limiting groove 504. Among them, the vertical height of the second protective cover 503 is greater than the vertical height of the groove 5, and the second protective cover 503 covers the outside of the groove 5. The second protective cover 503 can prevent the soil and Chinese herbal medicine seeds for seedling raising in the seedling-raising cylinder 306 from entering the groove 5 and causing the reciprocating lead screw 501 to malfunction. One end of one of the reciprocating lead screws 501 away from the second protective cover 503 is fixedly connected with a first gear 505. A second gear 506 is fixedly connected to one side of the blocking plate 307 near the first gear 505. The first gear 505 is meshed with the second gear 506. The first gear 505 and the second gear 506 are both located outside the seedling-raising cylinder 306. Among them, the number of teeth of the second gear 506 is greater than the number of teeth of the first gear 505. Thus, when the second gear 506 and the first gear 505 are synchronously meshed and rotated, the number of rotation circles of the first gear 505 is greater than the number of rotation circles of the second gear 506.

[0050] Initial state: The pull ring 203 is in a vertical state, the pull ring 203 fits on the surface of the connecting column 102 and is located between the two limiting blocks 205. Multiple seedling-raising cylinders 306 are located on the lower side of the conveyor belt 305.

[0051] Working process: Before transplantation, workers can add appropriate soil for the cultivation of Chinese herbal medicine seeds into multiple seedling raising cylinders 306 on the transplanting plate body 3, then bury the Chinese herbal medicine seeds to be planted into the soil, and then place the transplanting plate body 3 in an environment suitable for the growth of Chinese herbal medicine seeds, so that the Chinese herbal medicine seeds can develop into Chinese herbal medicine seedlings. When it is necessary to transplant the Chinese herbal medicine seedlings into the planting field, the worker first pulls the pull rings 203 at the four corners of the transplanting box 1, so that the pull rings 203 in the vertical state slide away from the side of the tension spring 204 between the two limit blocks 205, and the pull rings 203 gradually move away from the connecting column 102, and cause the tension spring 204 to contract under the extrusion of the baffle 202. When the pull rings 203 move from between the two limit blocks 205 to the outside of the limit blocks 205, the worker manually twists the pull rings 203 to rotate 90 degrees. At this time, the pull rings 203 change from the vertical state to the horizontal state. Then the worker releases the pull rings 203, and under the action of the elastic force of the tension spring 204, they are in contact with the side of the limit blocks 205 away from the tension spring 204. Similarly, the pull rings 203 at the four corners of the top of the transplanting box 1 are clamped on the limit blocks 205 in the same way. Then the worker places the transplanting plate body 3 with Chinese herbal medicine seedlings on the transplanting box 1, so that the hollow clamping blocks 206 at the four corners of the bottom of the transplanting plate body 3 are inserted into the card slots 2 on the connecting column 102. After the insertion is in place, the worker first pulls the pull rings 203 and rotates the pull rings 203 90 degrees to change them from the horizontal state to the vertical state, and drives the pull rings 203 to be clamped between the two corresponding limit blocks 205 through the tension spring 204. At this time, the sliding columns 201 slide along the inside of the card slot 2 with the tension spring 204, and the sliding columns 201 extend into the hole grooves at the central positions of the hollow clamping blocks 206. Thus, the transplanting plate body 3 can be quickly disassembled and replaced, so that the transplanting box 1 can load multiple transplanting plate bodies 3, thereby reducing the time required to replace the transplanting plate body 3, improving the overall transplanting efficiency, and at the same time, different transplanting plate bodies 3 can be replaced according to different types of Chinese herbal medicine seedlings, so as to adapt to different transplanting requirements.

[0052] After the transplanting plate body 3 with Chinese herbal medicine seedlings installed is completed, the worker sets the moving distance and staying time of the stepping motor 303 each time according to the spacing of the seedling-raising cylinders 306 through the controller, so that the stepping motor 303 automatically stops running when it moves the distance between the farthest seedling-raising cylinder 306 from the stepping motor 303 and the material discharging port 310 each time. Then, the stepping motor 303 is started to drive a transmission rod 302 fixedly connected thereto to slowly rotate towards the material discharging port 310. At this time, multiple conveying wheels 304 on the transmission rod 302 rotate slowly. Then, the multiple conveying wheels 304 drive the conveying wheels 304 on another transmission rod 302 to rotate synchronously through the conveyor belt 305 connected to them in transmission. Immediately, the other transmission rod 302 also rotates synchronously. At this time, the multiple seedling-raising cylinders 306 located on the conveyor belt 305 slowly move towards the material discharging port 310. Then, the seedling-raising cylinder 306 at the front end of the moving direction gradually approaches the trigger plate 311. Subsequently, the shorter part of the blocking plate 307 at the bottom of the seedling-raising cylinder 306 is blocked by the trigger plate 311 and rotates. The torsion spring 308 is gradually tightened by the extrusion of the blocking plate 307, so that the longer part of the blocking plate 307 gradually changes from being attached to the bottom of the seedling-raising cylinder 306 to not being attached to the bottom. And synchronously, through the rotation of the longer part of the blocking plate 307, the rubber pad 309 thereon is separated from the round opening at the bottom of the seedling-raising cylinder 306. Subsequently, the included angle between the longer part of the blocking plate 307 and the bottom of the seedling-raising cylinder 306 gradually increases. Until the stepping motor 303 reaches the set moving distance, the stepping motor 303 stops rotating, and the multiple seedling-raising cylinders 306 also stop moving accordingly. At this time, the seedling-raising cylinders 306 are located above the material discharging port 310, and the included angle between the longer part of the blocking plate 307 and the bottom of the seedling-raising cylinder 306 is the maximum value. Thus, automatic feeding can be carried out during the transplanting process of Chinese herbal medicine seedlings, without manual transplanting, which can save a large amount of transplanting time. This can not only improve the transplanting efficiency but also reduce the labor intensity of workers.

[0053] Meanwhile, during the rotation of the blocking plate 307, the second gear 506 thereon also rotates synchronously. Then, the second gear 506 drives the first gear 505 meshing with it to rotate in the opposite direction. The first gear 505 immediately drives the two reciprocating lead screws 501 to rotate in the same direction, causing the pressing plates 502 on the two reciprocating lead screws 501 to move towards each other along the inner wall of the surface of the second protective cover 503. During this process, the two arc-shaped pressing plates 502 gather the wet and loose soil in the seedling cultivation tube 306, prompting the wet and loose soil to be bonded to the outside of the Chinese herbal medicine seedlings under force and reducing the volume of the soil. Subsequently, when the pressing plate 502 moves to the intersection of the two reciprocating lead screws 501 along with the nut, the two reciprocating lead screws 501 drive the pressing plate 502 to move in the opposite direction through the nut, causing the pressing plate 502 to gradually move away from the second protective cover 503. Thus, the gathering of the soil can be released to facilitate the feeding of the soil and the Chinese herbal medicine seedlings, and further avoid the problem that the Chinese herbal medicine seedlings are not easily taken out from the transplanting plate body 3 during the transplanting process. This can effectively reduce the damage to the roots of the Chinese herbal medicine seedlings during the transplanting process, enabling them to adapt to the new environment and resume growth faster, thereby improving the survival rate of the transplanting of Chinese herbal medicine seedlings and further enhancing the transplanting efficiency of Chinese herbal medicine seedlings. At this time, the soil with reduced volume drives the Chinese herbal medicine seedlings thereon to slide downward from the bottom round opening of the seedling cultivation tube 306, causing the soil and the Chinese herbal medicine seedlings to slide from the longer side of the blocking plate 307 into the inner part of the feeding port 310, and then falling into the pit in the planting field under the action of gravity. Then, the worker covers the pit with soil, thus completing the transplanting and planting work of the Chinese herbal medicine seedlings. Subsequently, the seedling cultivation tube 306 after feeding continues to move forward along the conveyor belt 305, causing the blocking plate 307 at the bottom of the seedling cultivation tube 306 to disengage from the trigger plate 311. The torsion spring 308 loses its restriction and gradually returns to its original state. Then, the torsion spring 308 drives the blocking plate 307 to return to its original position and fit with the bottom of the seedling cultivation tube 306, causing the rubber pad 309 on the blocking plate 307 to coincide with the bottom round opening of the seedling cultivation tube 306. Then, the seedling cultivation tube 306 after feeding moves to the upper part of the transplanting plate body 3 along with the conveyor belt 305, causing the whole seedling cultivation tube 306 to deflect and be in an inverted state. After all the Chinese herbal medicine seedlings in multiple seedling cultivation tubes 306 on the conveyor belt 305 are fed, the conveyor belt 305 continues to drive the seedling cultivation tube 306 to move, causing multiple seedling cultivation tubes 306 to return to their original state, thus facilitating the subsequent Chinese herbal medicine seedling cultivation work again.

[0054] When it is necessary to adjust the distance between the Chinese herbal medicine seedlings, the worker first manually presses down the push-pull plates 405 located on both sides of the seedling tube 306, so that the push-pull plates 405 drive the limit frame 402 to slide downward along the inside of the slide groove 401, and then the latch teeth 403 on the top of the limit frame 402 also move down and disengage from the conveyor belt 305, and simultaneously make the convex strips on the latch teeth 403 not engage with the recesses of the conveyor belt 305. At this time, the worker pushes and pulls the seedling tube 306 horizontally to make it move horizontally along the surface of the conveyor belt 305, and repeats this cycle to adjust the distance between multiple seedling tubes 306. Thereby, the planting spacing between the Chinese herbal medicine seedlings in multiple seedling tubes 306 can be adjusted, which can optimize the growth environment of the Chinese herbal medicine seedlings, and then can effectively improve the transplant survival rate, thereby improving the quality and yield of Chinese herbal medicine.
