[0002] Wheat is one of the most important food crops in the world and is vital to human food security. In order to improve wheat yield, quality and stress resistance, breeders need to conduct a large number of complicated experiments and studies. For example, when screening wheat varieties and identifying traits in a laboratory or greenhouse, when conducting wheat hybrid breeding or wheat adversity breeding research, in order to ensure consistent plant growth conditions, accurately control the growth environment of each wheat plant or simulate a single different adversity condition, reduce the influence of other factors, etc., wheat breeding will be achieved using a plug tray. In the process of wheat breeding, it is necessary to first use tools to punch a plurality of planting holes on the planting plug tray, and then perform manual sowing.

[0022] The vibration assembly includes elastic rods fixedly connected to both ends of the second rotating shaft. A top column is fixedly connected to the top end of the elastic rod. A vibration block is fixedly connected to the bottom of the storage hopper. The vibration block is located directly above the top column.

[0023] According to the second aspect of the present invention, the present invention provides a method for dibbling and punching holes in wheat breeding, which adopts the above-mentioned dibbling and punching hole device for wheat breeding, and includes the following steps:

[0024] S1. First, pour the seeds into the storage hopper, place the seedling tray on the conveyor belt, and then rotate the second screw rod. Due to the meshing effect between the second screw rod and the cylinder body, the second screw rod moves in the cylinder body, thereby driving the baffle to move, and using the baffle to move the corrugated protective cover to an appropriate position for controlling the number of seeds for dibbling.

[0025] S2. Then rotate the first screw rod. Due to the meshing relationship between the first screw rod and the nut seat, drive the nut seat to move in the receiving groove, thereby adjusting the eccentricity of the nut seat. By adjusting the size of the eccentricity, adjust the stroke and amplitude of the movement, and adjust the punching position of the punching component to an appropriate depth.

[0026] S3. Then start the motor to drive the conveyor belt to move, and convey the seedling tray forward. At this time, the conveyor belt will drive the driving wheel to rotate. When the driving wheel rotates, the first transmission assembly will drive the first rotating shaft to rotate synchronously, thereby driving the disc to rotate accordingly.

[0027] S4. When the disc rotates, it will drive the traction rod to perform a periodic deflection movement. At this time, the traction rod will drive the gear set to move up and down reciprocally, thereby driving the punching component to move up and down reciprocally for realizing the punching operation on the seedling tray.

[0028] S5. When the first rotating shaft rotates, it will drive the second rotating shaft to rotate synchronously through the second transmission component. When the second rotating shaft rotates, it will drive several cylinders to rotate accordingly. When the opening formed on the cylinder moves upward to align with the discharge port, the seeds in the discharge hopper will fall downward into the interior of the cylinder. Then, as the cylinder continues to rotate, the opening moves into the dibbling hopper, and the seeds will fall downward into the dibbling hopper and then drop into the pre-dug hole.

[0029] The present invention has at least the following beneficial effects:

[0030] 1. High degree of automation, realizing synchronous operation of hole digging and dibbling:

[0031] Through the mutual cooperation of structures such as the conveyor belt, driving wheel, hole-digging component, and metering cylinder component provided in the present invention, the synchronous operation of hole digging and dibbling is realized. The up-and-down reciprocating movement of the hole-digging rod matches the speed of the quantitative seed delivery, ensuring that each hole can be accurately sown and avoiding the problems of low efficiency and errors caused by the separation of hole digging and sowing in traditional manual operations.

[0032] 2. Quantitative dibbling, accurately controlling the number of seeds:

[0033] Through the design of the cylinder, baffle, and corrugated protective cover in the present invention, the number of seeds dibbled each time can be flexibly adjusted. By rotating the second screw rod, the position of the baffle can be changed, thereby adjusting the capacity of seeds in the cylinder and realizing the quantitative delivery of different numbers of seeds. This design not only improves the sowing accuracy but also can adapt to different wheat varieties or breeding requirements.

[0034] 3. Adjustable hole spacing, adapting to various requirements:

[0035] In the present invention, the hole-digging rod and the connecting plate adopt a detachable installation design. Users can disassemble some hole-digging rods according to actual needs and flexibly adjust the spacing between adjacent holes in the same row. This design enables the device to adapt to different wheat breeding modes or test requirements, improving the versatility and practicality of the device.

[0036] 4. Anti-blocking design, ensuring smooth sowing:

[0037] During the process of seed dropping and dibbling, the device drives the elastic rod and the ejector pin to rotate through the second rotating shaft, and the ejector pin impacts the vibration block to vibrate the storage hopper and the discharge hopper. This vibration design effectively prevents seed blockage, ensures that the seeds can fall smoothly, and avoids the problem that the sowing progress of traditional devices is affected by seed blockage.

[0038] 5. Compact structure and simple operation:

[0039] The present invention integrates functions such as punching, dibbling, vibration, and anti-clogging. It has a compact structure design, is easy to operate. Users only need to start the motor to achieve fully automated operation, reducing manual intervention, lowering labor intensity, and improving work efficiency at the same time.

[0040] 7. Strong adaptability and high practical value:

[0041] The present invention is not only applicable to wheat breeding, but also can be adapted to the breeding needs of other crops by adjusting parameters such as the distance between punching rods and the seed delivery amount. Its modular design (such as detachable punching rods and adjustable seed capacity) further enhances the adaptability and practicality of the device, and can meet the breeding needs in different scenarios.

[0042] Of course, it is not necessary for any product implementing the present invention to achieve all the above-mentioned advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS

[0054] Next, the technical solutions in the embodiments of the present disclosure will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only a part of the embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present disclosure.

[0055] Embodiment 1:

[0056] Please refer to Figures 1-9 , the present invention provides a technical solution: a wheat breeding dibbling and hole punching device, including a base 1, a conveyor belt 2 is installed on the base 1, the top of the base 1 is fixedly connected with a machine case 3, the bottom of the machine case 3 is rotatably connected with a driving wheel 4, and the driving wheel 4 is in transmission connection with the conveyor belt 2;

[0057] A partition board 6 is fixedly connected inside the machine case 3, and a first rotating shaft 7 is rotatably connected inside the machine case 3. A first transmission assembly 8 is arranged between the first rotating shaft 7 and the driving wheel 4. One end of the first rotating shaft 7 is fixedly connected with a turntable assembly 9. A traction rod 10 is rotatably connected to the turntable assembly 9. The free end of the traction rod 10 is rotatably connected with a gear set 11. The two sides of the gear set 11 are respectively meshed with a first rack 12 and a second rack 13. The first rack 12 is fixedly connected with the partition board 6, the second rack 13 is slidably connected with the partition board 6, and a hole punching assembly 14 is fixed at the bottom of the second rack 13;

[0058] A storage hopper 15 is fixedly installed at the top of the chassis 3. A number of discharge hoppers 16 are fixedly installed below the storage hopper 15. A metering cylinder assembly 17 is rotatably connected below the discharge hopper 16. A second rotating shaft 24 is fixedly connected to the end of the metering cylinder assembly 17. And a seeding hopper 18 is installed below the metering cylinder assembly 17. The seeding hopper 18 is fixed on the partition plate 6.

[0059] A second transmission assembly 19 is arranged between the second rotating shaft 24 and the first rotating shaft 7. And a vibration assembly 20 is also installed on the second rotating shaft 24.

[0060] For the technical solution of this embodiment, a number of teeth 5 adapted to the driving wheel 4 are fixedly installed on the outer surface of the conveyor belt 2. When the conveyor belt 2 rotates, the driving wheel 4 is driven to rotate through the teeth 5, so as to realize the transmission connection between the two.

[0061] It should be noted that, as Figure 1 and Figure 2 shown, a motor 21 is fixedly connected to the side wall of the base 1 to provide a power source for the whole device. The motor 21 is powered by an external power supply. A driving roller is installed inside the conveyor belt 2. The output end of the motor 21 is fixedly connected to the driving roller. Starting the motor 21 to drive the driving roller to rotate can make the conveyor belt rotate, so as to realize the transportation of the seedling tray. And the seedling tray selects a suitable specification according to the growth characteristics of wheat.

[0062] For the technical solution of this embodiment, as Figure 1 shown, the first transmission assembly 8 includes synchronous wheels 81 fixedly connected to the driving wheel 4 and the first rotating shaft 7. A synchronous belt 82 is meshed on the synchronous wheels 81. When the driving wheel 4 rotates, the first rotating shaft 7 is driven to rotate by the synchronous belt 82 and the synchronous wheels 81. Since the rotation of the conveyor belt 2 will drive the driving wheel 4 to rotate through the teeth 5, when the driving wheel 4 rotates, it will drive the synchronous wheel 81 to rotate and drive the first rotating shaft 7 to rotate synchronously through the synchronous belt 82. It should be noted that the first transmission assembly 8 can also be set as a chain and a sprocket or a belt and a pulley. This embodiment does not make specific limitations here and can be selected according to actual situations.

[0063] For the technical solution of this embodiment, as Figure 6As shown in the figure, the turntable assembly 9 includes a disc 91 fixedly connected to the end of the first rotating shaft 7. A receiving groove is formed on the side wall of the disc 91. The receiving groove is set as a rectangular groove. A first screw rod 92 is rotatably connected inside the receiving groove. The first screw rod 92 is rotatably connected to the inner wall of the receiving groove through a bearing. A driven wheel 93 is fixedly connected to the first screw rod 92. The edge of the driven wheel 93 is meshed with a driving wheel 94. Both the driving wheel 94 and the driven wheel 93 are set as bevel gears 112. The driving wheel 94 is rotatably connected inside the receiving groove, and a first knob 95 is further fixedly connected to one side of the driving wheel 94. It should be noted that the first knob 95 penetrates through the side wall of the receiving groove. A nut seat 96 is meshed with the outer surface of the first screw rod 92. The width of the nut seat 96 is adapted to the width of the receiving groove. The nut seat 96 is rotatably connected to the traction rod 10. During actual use, the rotation of the first rotating shaft 7 will drive the disc 91 to rotate. Since the nut seat 96 is arranged at an eccentric position of the disc 91, when the disc 91 rotates, it will drive the nut seat 96 to perform an eccentric rotational motion, thereby driving the traction rod 10 to perform a periodic deflection, and then driving the gear set 11 and the hole punching assembly 14 to perform a periodic reciprocating motion, so as to punch holes in the seedling tray. And when the first knob 95 is rotated, it will drive the driving wheel 94 to rotate, and drive the driven wheel 93 to rotate through the driving wheel 94, thereby driving the first screw rod 92 to rotate. When the first screw rod 92 rotates, the meshing relationship between the first screw rod 92 and the nut seat 96 can drive the nut seat 96 to move in the receiving groove, so as to adjust the distance of the nut seat 96 from the center of the circle (eccentric distance). By adjusting the size of the eccentric distance, the stroke and amplitude of the motion can be adjusted, so as to control the stroke of the reciprocating motion of the hole punching assembly 14 and facilitate controlling the hole punching depth according to actual needs.

[0064] Regarding the technical solution of this embodiment, as Figure 3As shown in the figure, the gear set 11 includes a third rotating shaft 111 rotatably connected to the end of the towing bar 10. At least two sets of gears 112 are installed on the third rotating shaft 111. The number of the first rack 12 and the second rack 13 corresponds to that of the gears 112. When the disc 91 rotates to drive the towing bar 10 to rotate accordingly, the towing bar 10 will first drive upward and deflect to move above the disc 91. At this time, the towing bar 10 will drive the third rotating shaft 111 and the two sets of gears 112 to move upward. Since the first rack 12 is fixed to the partition plate 6 and the second rack 13 is slidably connected to the partition plate 6, when the gears 112 move upward, they will rotate due to the meshing interaction of the first gears 112. At this time, the gears 112 will drive the second rack 13 to slide upward. Then, as the disc 91 continues to rotate, the towing bar 10 will deflect downward to the bottom end of the disc 91. At this time, the gears 112 will move downward and rotate, thereby driving the second rack 13 to slide downward. By repeating this process, the second rack 13 can reciprocate up and down, thereby driving the hole punching assembly 14 to move up and down accordingly to perform the hole punching operation on the seedling tray. The reason for using structures such as the gear set 11, the first rack 12, and the second rack 13 to achieve the reciprocation of the hole punching assembly 14 is mainly that during the process of the towing bar 10 driving the gear set 11 to move upward, if the gear set 11 does not rotate, it will drive the second rack 13 to move upward (downward) a distance of the first stroke. However, due to the action of the first rack 12, the gear set 11 rotates. Therefore, the rotation of the gear set 11 itself can also drive the second rack 13 to move upward (downward) a distance of the second stroke on the basis of the first stroke. Compared with the traditional method, it can achieve an effect of increasing the stroke, ensuring the depth and quality of the hole punching;

[0065] Furthermore, as Figure 3 shown in the figure, a guide bar 113 is fixedly connected to the side wall of the second rack 13. A retaining ring is fixedly connected to the top end of the guide bar 113. A limiting block 114 is slidably connected to the guide bar 113, and the limiting block 114 is fixedly connected to the partition plate 6. When the second rack 13 moves up and down, the guide bar 113 and the limiting block 114 can provide good support, limiting, and guiding effects for it, improving its stability during movement. Moreover, by using the provided retaining ring, it can also prevent the guide bar 113 from slipping off the limiting block 114.

[0066] Regarding the technical solution of this embodiment, as Figure 9As shown, the hole punching assembly 14 includes a connecting plate 141 fixedly connected to the bottom end of the second rack 13. A hole punching rod 142 is detachably installed at the bottom end of the connecting plate 141. It should be noted that the hole punching rod 142 is made of wear-resistant metal, such as high manganese alloy. The hole punching rod 142 and the connecting plate 141 are detachably connected by means of threaded connection. A stud is fixedly connected to the top end of the hole punching rod 142, and a threaded hole adapted to the stud is provided at the bottom of the connecting plate 141. By disassembling part of the hole punching rod 142, the distance between adjacent hole holes in the same row can also be controlled, so as to facilitate adaptation to different requirements.

[0067] Regarding the technical solution of this embodiment, as Figure 3 shown, the second transmission assembly 19 includes a first transmission wheel 191 fixedly connected to the first rotating shaft 7 and a second transmission wheel 192 fixedly connected to the second rotating shaft 24. A third transmission wheel 193 is meshed between the first transmission wheel 191 and the second transmission wheel 192, and the third transmission wheel 193 is rotatably connected to the inner wall of the chassis 3. When the first rotating shaft 7 rotates, it will drive the first transmission wheel 191 to rotate, and drive the third transmission wheel 193 to rotate through the first transmission wheel 191, thereby driving the second transmission wheel 192 to rotate. When the second transmission wheel 192 rotates, it will drive the second rotating shaft 24 to rotate.

[0068] Regarding the technical solution of this embodiment, as Figure 4 shown, the number of the discharge hopper 16, the positioning cylinder assembly and the hole punching rod 142 corresponds. The positioning cylinder assembly includes a plurality of cylinders 171 fixedly installed on the second rotating shaft 24. Adjacent cylinders 171 are fixedly connected. An opening 172 is provided on the side wall of the cylinder 171. The discharge hopper 16 communicates with the storage hopper 15. A discharge port is provided at the bottom of the discharge hopper 16. When the second rotating shaft 24 rotates, it will drive a plurality of cylinders 171 to rotate accordingly. When the opening 172 provided on the cylinder 171 moves upward to correspond to the discharge port, the seeds in the discharge hopper 16 will fall downward into the inside of the cylinder 171. Then, as the cylinder 171 continues to rotate, the opening 172 moves into the dibbling hopper 18, and the seeds will fall downward into the dibbling hopper 18. A blanking pipe 23 is fixedly connected below the dibbling hopper 18. The blanking pipe 23 is arranged in a bent shape. The seeds falling into the dibbling hopper 18 will fall into the punched hole through the blanking pipe 23. And since the position of the opening 172 is inside the dibbling hopper 18 when it moves to the lower part, the seeds will not be scattered outward due to external wind force or other external forces during the falling process, ensuring the stable falling of the seeds.

[0069] It should be noted that, as Figure 8As shown, an arc-shaped groove adapted to the cylinder body 171 is formed at the bottom of the discharging hopper 16. The discharging hopper 16 is in close fit with the cylinder body 171. By rotating the cylinder body 171, the opening or closing of the discharging port can be realized. And a scraping strip 22 is fixedly connected to the side wall of the discharging port. By providing the scraping strip 22, not only can the sealing performance between the cylinder body 171 and the discharging hopper 16 be enhanced, but also the seeds that do not enter the interior of the cylinder body 171 can be scraped off.

[0070] Furthermore, as Figure 7 shown, a baffle 173 is slidably connected inside the cylinder body 171. One side of the baffle 173 is rotatably connected to a second screw rod 174. The second screw rod 174 is threadedly connected to the cylinder body 171. One side of the baffle 173 is fixedly connected to a corrugated protective cover 175, and the other end of the corrugated protective cover 175 is fixed to the cylinder body 171. During actual use, if it is necessary to adjust the number of seeds sown each time, rotate the second screw rod 174. Due to the meshing effect between the second screw rod 174 and the cylinder body 171, the second screw rod 174 moves inside the cylinder body 171, thereby driving the baffle 173 to move. When the baffle 173 moves, it will drive the corrugated protective cover 175 to unfold or be stored. When the corrugated protective cover 175 unfolds, the number of seeds stored inside the cylinder body 171 can be increased. On the contrary, the number of seeds stored inside the cylinder body 171 can be reduced. In this way, the quantitative feeding of different numbers of seeds can be realized, further improving the practicability of the device. And when the corrugated protective cover 175 unfolds, it has a certain hardness to support, so it can support the pressure of the seeds above. And when the corrugated protective cover 175 rotates to the upper side, if there are seeds remaining on the corrugated protective cover 175, the scraping strip 22 provided can also scrape off the seeds. And the distance between adjacent cylinder bodies 171 can satisfy the movement of the second screw rod 174 until the corrugated protective cover 175 is completely stored without causing interference.

[0071] Furthermore, a chute is formed at the edge of the opening 172. A sliding block adapted to the chute is fixedly connected to the side wall of the baffle 173 that fits with the opening 172. By providing the chute and the sliding block, the baffle 173 can be limited and guided, enhancing the stability of the movement of the baffle 173.

[0072] It should be further noted that after a certain punching rod 142 in the punching assembly 14 is disassembled, by completely unfolding the corrugated protective cover 175 of the corresponding cylinder body 171, the opening 172 on the cylinder body 171 can be completely closed, making the cylinder body 171 form a completely closed cylinder. At this time, when the cylinder body 171 rotates below the discharging hopper 16, it will always close the discharging port to prevent seeds from falling.

[0073] Regarding the technical solution of this embodiment, as Figure 5As shown, the vibration assembly 20 includes elastic rods 201 fixedly connected to both ends of the second rotating shaft 24. A top column 202 is fixedly connected to the top end of the elastic rod 201, and a vibration block 203 is fixedly connected to the bottom of the storage hopper 15. The vibration block 203 is located directly above the top column 202. When the second rotating shaft 24 rotates, it will also drive the elastic rod 201 and the top column 202 to rotate. The top column 202 is set to be hemispherical, and the lower part of the vibration block 203 is also set to be an arc surface. When the top column 202 moves quickly, it will impact the vibration block 203. At this time, the vibration block 203 will drive the storage hopper 15 and the discharge hopper 16 to vibrate, facilitating the smooth falling of the seeds, avoiding the blockage of the seeds and affecting the seeding progress. And the elastic rod 201 provided can make the top column 202 contract under the extrusion of the vibration block 203, enabling the top column 202 to pass through smoothly and avoiding interference.

[0074] The operating principle and process of the present invention: When wheat breeding is required, first pour the seeds into the storage hopper 15, place the seedling tray on the conveyor belt 2, start the motor 21 to drive the conveyor belt 2 to move, and convey the seedling tray forward. At this time, the conveyor belt 2 will drive the driving wheel 4 to rotate through the teeth 5. When the driving wheel 4 rotates, the first transmission component 8 will drive the first rotating shaft 7 to rotate synchronously, thereby driving the disc 91 to rotate accordingly. When the disc 91 rotates and drives the traction rod 10 to rotate accordingly, it will first drive the traction rod 10 to deflect upward and move above the disc 91. At this time, the traction rod 10 will drive the third rotating shaft 111 and the two groups of gears 112 to move upward. Since the first rack 12 is fixed on the partition 6 and the second rack 13 is slidably connected to the partition 6, when the gears 112 move upward, they will rotate due to the meshing action of the first gear 112. At this time, the gears 112 will drive the second rack 13 to slide upward. Then, as the disc 91 continues to rotate, the traction rod 10 will deflect downward to the bottom of the disc 91. At this time, the gears 112 will move downward and rotate, thereby driving the second rack 13 to slide downward. By repeating this process, the second rack 13 can move up and down reciprocally, thereby driving the connecting plate 141 and the hole punching rod 142 to move up and down to perform the hole punching operation on the seedling tray. Then, when the first rotating shaft 7 rotates, it will drive the first transmission wheel 191 to rotate, and drive the third transmission wheel 193 to rotate through the first transmission wheel 191, thereby driving the second transmission wheel 192 to rotate. When the second transmission wheel 192 rotates, it will drive the second rotating shaft 24 to rotate. When the second rotating shaft 24 rotates, it will drive a number of cylinders 171 to rotate accordingly. When the opening 172 provided on the cylinder 171 moves upward to correspond to the discharge port, the seeds in the discharge hopper 16 will fall downward into the inside of the cylinder 171. Then, as the cylinder 171 continues to rotate, the opening 172 moves into the dibbling hopper 18, and the seeds will fall downward into the dibbling hopper 18 and then fall into the punched holes. Moreover, the hole punching speed will match the seed dibbling speed. In this way, the seeds can be automatically quantitatively dibbled while punching holes, realizing a flow operation. During actual use, if it is necessary to adjust the number of seeds dibbled each time, rotate the second screw rod 174. By using the meshing action between the second screw rod 174 and the cylinder 171, the second screw rod 174 moves inside the cylinder 171, thereby driving the baffle 173 to move. When the baffle 173 moves, it will drive the corrugated protective cover 175 to unfold or be received. When the corrugated protective cover 175 unfolds, the quantity of seeds contained inside the cylinder 171 can be increased. On the contrary, the quantity of seeds contained inside the cylinder 171 can be reduced. In this way, quantitative feeding of different numbers of seeds can be achieved, further improving the practicability of the device;And since the punching rod 142 and the connecting plate 141 are detachably installed, the distance between adjacent holes in the same row can be controlled by disassembling some of the punching rods 142, so as to facilitate adaptation to different requirements. At this time, by fully expanding the corrugated protective cover 175 of the corresponding cylinder 171, the opening 172 on the cylinder 171 can be completely closed to prevent seeds from falling at the corresponding position. At the same time, during the process of seed dropping and dibbling, the second rotating shaft 24 will also drive the elastic rod 201 and the ejector pin 202 to rotate. When the ejector pin 202 moves quickly, it will impact the vibration block 203. At this time, the vibration block 203 will drive the storage hopper 15 and the discharge hopper 16 to vibrate, facilitating the smooth falling of seeds and preventing seed blockage from affecting the dibbling progress.

[0075] Embodiment 2:

[0076] This embodiment provides a wheat breeding dibbling and punching method, which uses a wheat breeding dibbling and punching device described in Embodiment 1 and includes the following steps:

[0077] S1. First, pour the seeds into the storage hopper 15, place the seedling tray on the conveyor belt 2, and then rotate the second screw rod 174. By using the meshing effect between the second screw rod 174 and the cylinder 171, the second screw rod 174 moves in the cylinder 171, thereby driving the baffle 173 to move, and using the baffle 173 to move the corrugated protective cover 175 to an appropriate position for controlling the number of seeds for dibbling;

[0078] S2. Then rotate the first screw rod 92. By using the meshing relationship between the first screw rod 92 and the nut seat 96, drive the nut seat 96 to move in the receiving groove, thereby adjusting the eccentricity of the nut seat 96, and by adjusting the size of the eccentricity, adjusting the stroke and amplitude of the movement, and adjusting the punching position of the punching assembly 14 to an appropriate depth

[0079] S3. Then start the motor 21 to drive the conveyor belt 2 to move, and convey the seedling tray forward. At this time, the conveyor belt 2 will drive the driving wheel 4 to rotate. When the driving wheel 4 rotates, the first transmission assembly 8 will drive the first rotating shaft 7 to rotate synchronously, thereby driving the disc 91 to rotate accordingly;

[0080] S4. When the disc 91 rotates, it will drive the traction rod 10 to perform periodic deflection movements. At this time, the traction rod 10 will drive the gear set 11 to move up and down reciprocally, thereby driving the punching assembly 14 to move up and down reciprocally for realizing the punching operation on the seedling tray;

[0081] S5. When the first rotating shaft 7 rotates, it will drive the second rotating shaft 24 to rotate synchronously through the second transmission assembly 19. When the second rotating shaft 24 rotates, it will drive a plurality of cylinders 171 to rotate accordingly. When the opening 172 formed on the cylinder 171 moves upward to correspond to the discharge port, the seeds in the discharge hopper 16 will fall downward into the interior of the cylinder 171. Then, as the cylinder 171 continues to rotate, the opening 172 moves into the dibbling hopper 18, and the seeds will fall downward into the dibbling hopper 18 and then fall into the drilled holes.
