Description

Technical Field

[0001] This invention relates to the field of organic Bupleurum chinense planting equipment technology, specifically to a hole-type planting device and its planting method for organic Bupleurum chinense planting. Background Technology

[0002] The perforated seeding device for organic Bupleurum chinense cultivation is an advanced mechanized seeding tool. Its core function is to achieve efficient and uniform seeding by precisely controlling the seeding depth, density, and soil covering process, thereby improving planting efficiency and crop yield. In actual operation, the land needs to be pre-treated before planting. First, ridging is carried out. After ridging, weed control cloth is covered on the ridge surface from top to bottom according to the direction of the ridge, ensuring that the weed control cloth is tightly attached to the soil surface. The use of weed control cloth can not only effectively suppress weed growth, but also reduce the amount of weeding work. Next, according to the predetermined planting density, a reasonable row spacing and hole spacing are determined, and holes are made in the weed control cloth. The position and number of holes need to be precisely calculated according to the growth characteristics and planting requirements of Bupleurum chinense seeds. Finally, the perforated seeding device accurately puts the Bupleurum chinense seeds into the pre-drilled seeding holes. The perforated seeding device is usually equipped with a precision seed metering device and positioning system, which can ensure that each seed is accurately put into the predetermined position and avoid missed or double seeding.

[0003] Traditional organic Bupleurum chinense planting using perforated sowing equipment requires pre-treatment of the weed control fabric. This process typically relies on an external heat source, such as heated coal, to provide heat. The coal is then fed into the perforating device, which is manually used to create holes in the fabric. Once the perforated fabric is opened, the Bupleurum chinense is sown using the perforated sowing equipment. However, manually opening holes in the fabric makes it difficult to precisely control the sowing spacing, ensuring that each plant receives sufficient growing space and nutrients. This also increases the labor and time costs of Bupleurum chinense planting, failing to meet the demands of modern agriculture for efficient, precise, and low-cost cultivation.

[0004] Secondly, traditional organic Bupleurum cultivation using perforated planting equipment involves several steps. First, the planter is inserted into the soil to create a planting hole. Then, a seed metering device retrieves the appropriate number of Bupleurum seeds and places them at the bottom of the planting hole. Finally, the planter is removed, and a soil covering device covers the planting hole to cover the seeds. During this process, all the Bupleurum seeds are concentrated at the bottom of the planting hole, causing them to pile up. This piling up leads to competition among the seeds for limited nutrients and growing space, preventing them from evenly accessing moisture, nutrients, and oxygen from the soil, thus significantly reducing the growth potential of Bupleurum. Seed germination rate and seedling survival rate are affected. In addition, seed piling may lead to uneven seedling growth, with some seedlings developing poorly due to insufficient nutrients, affecting the overall planting effect. Furthermore, when covering seeds with soil, the soil covering device cannot precisely control the thickness of the soil covering. If the soil covering is too thick, it will block the light and oxygen required for seed germination, delaying the germination time or even preventing the seeds from breaking through the soil. If the soil covering is too thin, the seeds may be exposed on the soil surface, making them susceptible to the influence of the external environment and reducing the seed survival rate. Uneven soil covering thickness will also lead to uneven seedling growth, affecting the efficiency of field management and the overall crop yield.

[0005] To address the aforementioned issues, there is an urgent need for innovative design based on the existing perforated sowing equipment used for organic Bupleurum chinense cultivation. Summary of the Invention

[0006] This invention addresses the problem of overly simplistic solutions in existing technologies by providing a significantly different approach. Specifically, the invention aims to provide a perforated sowing device and method for organic Bupleurum chinense cultivation. This addresses the issues raised in the background, such as the inability to precisely control the sowing spacing due to manual handheld devices, which affects Bupleurum chinense's growth space and nutrient acquisition, increases labor and time costs, and fails to meet the demands of modern agriculture for high efficiency, precision, and low cost. Furthermore, it addresses the problems of seeds accumulating at the bottom of the planting holes, leading to competition for limited nutrients and growth space, reducing germination and seedling survival rates, and uneven soil covering affecting seed germination and seedling growth.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a hole-type sowing device for organic Bupleurum chinense cultivation, comprising a traction frame and two sets of rollers symmetrically arranged at the bottom of the traction frame, and further comprising two operating components controlled by the rolling of the two sets of rollers respectively. The operating components include two connecting plates driven by the same set of rollers to move in a wave-like manner, a punching component that follows the connecting plates to move periodically, a sowing component that follows the connecting plates to sow seeds at different depths step by step, and a rotating ring that moves adaptively following the sowing component. The bottom of the rotating ring is provided with a plurality of levers that move adaptively as the rotating ring moves.

[0008] Preferably, the operating assembly further includes a support plate fixedly connected to the bottom of the traction frame. A rotating shaft is rotatably connected to the end of the support plate. A first synchronous pulley is fixedly connected to the surface of the rotating shaft. A second synchronous pulley is fixedly connected to the central shaft surface of one of the rollers in the same group. A belt is fitted on the surfaces of the first synchronous pulley and the second synchronous pulley. Rotating seats are fixedly connected to both ends of the rotating shaft of the support plate. The two rotating seats are rotatably connected to the side walls of the two connecting plates respectively. Rotating plates are rotatably connected to both ends of one of the connecting plates. The two rotating plates are fixedly connected to the central shaft surfaces of the two rollers in the same group respectively. Linkage pins are rotatably connected to both ends of the other connecting plate. The two linkage pins are fixedly connected to the side walls of the two rollers in the same group respectively.

[0009] Preferably, the punching assembly is installed at the bottom of the connecting plate, a heating tube is fixedly connected inside the punching assembly, a heating controller is fixedly connected to the top of the traction frame, and each heating tube is electrically connected to the heating controller via an electric wire.

[0010] Preferably, the sowing assembly includes a feeding device fixedly installed on the top of the traction frame, the outlet of the feeding device is fixedly connected to a seed metering device, the outlet of the seed metering device is fixedly connected to a connecting pipe through a flexible hose, the end of the connecting pipe is fixedly inserted through a connecting plate, the surface of the connecting pipe is provided with external threads, and the inner wall of the rotating ring is threadedly connected to the external threads on the surface of the connecting pipe through the internal threads.

[0011] Preferably, the outer wall of the rotating ring has a groove, and a sleeve is movably connected inside the groove. A spring is fitted inside the groove on the outer wall of the rotating ring, with one end of the spring fixedly connected to the bottom of the sleeve and the other end of the spring fixedly connected to the inner wall of the groove.

[0012] Preferably, multiple actuating rods are evenly fixed at the bottom of the sleeve at equal angles, and each actuating rod passes through the lower end of the rotating ring. The bottom of the rotating ring is provided with multiple sliding grooves at equal angles to cooperate with the sliding of the actuating rods. A torsion spring is provided between the rotating ring and the connecting plate, which is wound around the outer wall of the connecting tube. One end of the torsion spring is fixed to the lower surface of the connecting plate, and the other end of the torsion spring is fixed to the upper surface of the rotating ring.

[0013] Preferably, the bottom of the traction frame is fixedly connected with four fixed rods at equal intervals, and each connecting plate has a groove on one side for making way for the fixed rods.

[0014] A method for planting organic Bupleurum chinense using a hole-planting method, comprising the following steps:

[0015] S1. The connecting plate is moved in a wave-like motion by the rolling of the rollers. During the downward movement of the connecting plate, the weed control fabric is perforated by the perforation component.

[0016] S2. Simultaneously, the downward-moving connecting plate will cause the connecting pipe and rotating ring to insert into the soil. When the lower surface of the upper end of the rotating ring is blocked by the soil, it cannot continue to be inserted. Since the connecting pipe and the rotating ring are threaded, as the connecting pipe continues to fall with the connecting plate, the rotating ring will rotate on the outer wall of the connecting pipe.

[0017] S3. The Bupleurum seeds are transported to the bottom of the rotating ring by the sowing component. When the connecting plate rises, the sleeve stays inside the soil due to friction between the sleeve and the soil. This causes the connecting plate to drive the connecting pipe and the rotating ring to rise separately, thereby compressing the spring. At this time, the actuating rod fixedly connected to the bottom of the sleeve is exposed from inside the rotating ring. During the subsequent upward movement, it actuates the soil on the inner wall of the planting hole.

[0018] S4. When the connecting plate moves the connecting pipe and the rotating ring to the position of the fixed rod, the top of the rotating ring is pressed by the fixed rod. As the connecting pipe moves the rotating ring upward, the rotating ring rotates around the connecting pipe and moves down to the initial position of the rotating ring and the connecting pipe before drilling and sowing.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] 1. The connecting plate is movably connected to both sides of two sets of rollers by four rotating plates and connecting shafts. The rotation of the rollers drives the connecting plate to move periodically. The rotation of the rollers and rotating plates drives the perforating component to move down and open holes in the weed control cloth. Then, the rotation of the rollers and rotating plates drives the sowing component to move down to the opening for sowing. The periodic rotation of the two sets of rollers accurately determines the planting spacing of Bupleurum seeds. Moreover, the mechanical perforation method reduces the labor cost of Bupleurum planting.

[0021] 2. The connecting plate drives the connecting pipe and rotating ring to move downwards. When the lower surface of the upper end of the rotating ring is blocked by the soil, the rotating ring cannot continue to move downwards. At this time, the connecting pipe continues to move downwards under the action of the connecting plate. Since the connecting pipe and the rotating ring are connected by threads, the rotating ring is driven to rotate. The connecting plate also drives the rotating ring to rise. Due to the friction between the sleeve and the soil, the sleeve stays inside the soil. This causes multiple sets of actuating rods fixed at the bottom of the sleeve to be exposed outside the rotating ring, which agitates the soil on the inner wall of the sowing hole. As the connecting plate drives the connecting pipe to rise, the seeds are covered with soil at different depths, thus achieving the effect of sowing Bupleurum seeds at different depths.

Detailed Implementation

[0031] 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 skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Please see Figures 1 to 8 The present invention provides a technical solution: a hole-type sowing device for organic Bupleurum cultivation, including a traction frame 1 and two sets of rollers 5 symmetrically arranged at the bottom of the traction frame 1, including two operating components controlled by the rolling of the two sets of rollers 5 respectively. The operating components include two connecting plates 8 driven by the same set of rollers 5 to move in a wave-like manner, a hole-punching component 7 that follows the connecting plates 8 to move periodically, a sowing component that follows the connecting plates 8 to sow seeds at different depths step by step, and a rotating ring 10 that moves adaptively following the sowing component. The bottom of the rotating ring 10 is provided with a plurality of actuating rods 13 that move adaptively with the movement of the rotating ring 10.

[0033] In practice, the equipment consists of a traction frame 1 and two sets of symmetrically arranged rollers 5. The rollers 5 control the two operating components through rolling. The rotation of the rollers 5 drives the connecting plate 8 to move in a wave-like motion, which in turn drives the perforating component 7 and the sowing component to move periodically. During the perforation operation, the connecting plate 8 moves downward under the drive of the rollers 5, driving the perforating component 7 to perforate the weed control cloth or soil to prepare for sowing. At the same time, the downward movement of the connecting plate 8 drives the sowing component to sow at different depths step by step. When the perforating component 7 and the sowing component move downward together, the sowing position of the sowing component is the hole opened by the perforating component 7 in the previous operation. The seed assembly, through the coordinated operation of the rotating ring 10 and the actuating rod 13, ensures that the seeds fall precisely into the drilled holes. The bottom of the rotating ring 10 is equipped with multiple actuating rods 13. As the rotating ring 10 moves, the actuating rods 13 adaptively agitate the soil. During the sowing process, the actuating rods 13 agitate the soil on the inner wall of the sowing hole to ensure that the seeds are in full contact with the soil and to achieve gradual soil covering. The periodic rotation of the roller 5 drives the connecting plate 8 to move in a wave-like manner, thereby realizing the automated operation of drilling, sowing and soil covering. Through mechanized periodic movement, the planting spacing and sowing depth of Bupleurum seeds are precisely controlled, improving sowing efficiency and accuracy.

[0034] As a further embodiment of the present invention, the support plate 2 is fixedly connected to the bottom of the traction frame 1. A rotating shaft is rotatably connected to the end of the support plate 2, and a first synchronous pulley is fixedly connected to the surface of the rotating shaft for transmitting power. A second synchronous pulley is fixedly connected to the central shaft surface of one of the rollers 5 in the same group. The first and second synchronous pulleys are connected by a belt 3 to realize the synchronous transmission of power. Rotating seats 6 are fixedly connected to both ends of the rotating shaft of the support plate 2. The rotating seats 6 are rotatably connected to the side walls of two connecting plates 8 respectively. A rotating plate 4 is rotatably connected to both ends of one of the connecting plates 8. The rotating plate 4 is connected to the side walls of the rollers in the same group. The central shaft of the roller 5 is fixedly connected to realize the linkage between the roller 5 and the connecting plate 8. The two ends of the other connecting plate 8 are rotatably connected with linkage pins. The linkage pins are fixedly connected to the side wall of the roller 5 in the same group. Through the linkage pins, it is ensured that the rotation of the roller 5 can drive the connecting plate 8 to perform periodic movement. The rotation of the roller 5 is transmitted to the first synchronous pulley through the second synchronous pulley and the belt 3, which drives the rotating shaft and the rotating seat 6 to rotate. The rotating seat 6 drives the connecting plate 8 to move in a wave-like manner, thereby driving the punching component 7 and the seeding component to work. The rotating plate 4 and the linkage pins ensure that the power transmission between the roller 5 and the connecting plate 8 is stable and reliable.

[0035] In practice, the rotating plate 4 is fixed to the bottom of the traction frame 1 by the support plate 2. The rotating plate 4 is connected to the roller 5 by the belt 3. The rotation of the roller 5 drives the rotating plate 4 to rotate synchronously and periodically through the belt 3, thereby driving the drilling and sowing components to perform equal-interval operations, and finally achieving equal-interval precise sowing of organic Bupleurum.

[0036] As a further embodiment of the present invention, the punching assembly 7 is installed at the bottom of the connecting plate 8, and a heating tube 17 is fixedly connected inside the punching assembly 7. A heating controller 20 is fixedly connected to the top of the traction frame 1, and each heating tube 17 is electrically connected to the heating controller 20 through a wire.

[0037] In practice, the punching assembly 7 is installed at the bottom of the connecting plate 8, and a heating tube 17 is fixedly connected inside it. The heating tube 17 is electrically connected to the heating controller 20 at the top of the traction frame 1 through an electric wire. The heating controller 20 adjusts the temperature of the heating tube 17 so that the punching assembly 7 can soften the weed control cloth when punching, thereby improving the punching efficiency.

[0038] As a further embodiment of the present invention, the sowing assembly includes a feeding device 18 fixedly installed on the top of the traction frame 1. The outlet of the feeding device 18 is fixedly connected to a seed metering device 19. The outlet of the seed metering device 19 is fixedly connected to a connecting pipe 9 through a hose 16. The end of the connecting pipe 9 is fixedly connected through a connecting plate 8. The surface of the connecting pipe 9 is provided with an external thread. The inner wall of the rotating ring 10 is threadedly connected to the external thread on the surface of the connecting pipe 9 through the internal thread.

[0039] In specific implementation, the sowing assembly includes a feeding device 18 fixed on the top of the traction frame 1, whose outlet is connected to a seed metering device 19. The seed metering device 19 is connected to a connecting pipe 9 through a hose 16. The connecting pipe 9 passes through the connecting plate 8 and is connected to the internal thread of the inner wall of the rotating ring 10 through the external thread, so as to realize the threaded linkage between the rotating ring 10 and the connecting pipe 9. Thus, when the connecting pipe 9 moves up and down, it drives the rotating ring 10 to rotate, thereby completing the sowing and covering operations.

[0040] As a further embodiment of the present invention, the outer wall of the rotating ring 10 is provided with a groove, and a sleeve 11 is movably connected inside the groove. A spring 12 is sleeved inside the groove of the outer wall of the rotating ring 10, and one end of the spring 12 is fixedly connected to the bottom of the sleeve 11, and the other end of the spring 12 is fixedly connected to the inner wall of the groove.

[0041] In specific implementation, the outer wall of the rotating ring 10 is provided with a groove, and a sleeve 11 is movably connected in the groove. The bottom of the sleeve 11 is connected to the inner wall of the groove by a spring 12, so that the sleeve 11 can adaptively adjust its position due to the extension and contraction of the spring 12 when the rotating ring 10 moves, thereby realizing the function of the agitator 13 to move the soil on the inner wall of the seeding hole and cover it with soil (supplementary note: when the sleeve 11 enters the soil, soil may stick in the gap of the spring 12, but the elasticity of the spring 12 is large and will not affect the reset of the spring 12).

[0042] As a further embodiment of the present invention, multiple actuating rods 13 are evenly fixed at the bottom of the sleeve 11 at equal angles, and each actuating rod 13 passes through the lower end of the rotating ring 10. The bottom of the rotating ring 10 is provided with multiple sliding grooves at equal angles to cooperate with the sliding of the actuating rods 13. A torsion spring is provided between the rotating ring 10 and the connecting plate 8, which is wound around the outer wall of the connecting pipe 9. One end of the torsion spring is fixed to the lower surface of the connecting plate 8, and the other end of the torsion spring is fixed to the upper surface of the rotating ring 10.

[0043] In specific implementation, multiple actuating rods 13 are evenly fixed at the bottom of the sleeve 11 at equal angles and pass through the lower end of the rotating ring 10. The bottom of the rotating ring 10 is provided with a sliding groove corresponding to the actuating rod 13, so that the actuating rod 13 can slide along the sliding groove when the rotating ring 10 moves, thereby agitating the soil after sowing to achieve uniform soil covering and full contact between the seeds and the soil. The rotating ring 10 can be reset by the torsion spring wrapped around the outer wall of the connecting pipe 9 in conjunction with the push of the actuating rod 13 (supplementary explanation: since the rotating ring 10 is passively rotated when it is rigidly inserted into the soil, when it is reset, it needs to be pressed by the fixing rod 14 to make the rotating ring 10 receive a downward forced starting force and start rotating along the thread of the outer wall of the connecting pipe 9. Then the rotating ring 10 is disengaged from the fixing rod 14, and at this time the rotating ring 10 will continue to reset downward under the action of the torsion spring).

[0044] As a further embodiment of the present invention, four fixing rods 14 are fixedly connected at equal intervals at the bottom of the traction frame 1, and each connecting plate 8 has a groove 15 on one side for making way for the fixing rods 14.

[0045] In practice, four fixed rods 14 are fixed at equal intervals at the bottom of the traction frame 1. Each connecting plate 8 has a sliding groove 15 on one side. The sliding groove 15 provides clearance for the fixed rods 14, so that the connecting plate 8 can slide along the fixed rods 14 when moving up and down, ensuring the stability of the movement trajectory of the connecting plate 8 and avoiding deviation or jamming.

[0046] A sowing method for a perforated sowing device used for organic Bupleurum chinense cultivation, the sowing method comprising the following steps:

[0047] S1. The connecting plate 8 is driven to move in a wave-like manner by the rotating seat 6 and the roller 5. During the downward movement of the connecting plate 8, the weed control cloth is perforated by the perforation assembly 7.

[0048] S2. Simultaneously, the downward-moving connecting plate 8 will drive the connecting pipe 9 and the rotating ring 10 to insert into the soil. When the top of the rotating ring 10 is blocked by the soil, it cannot continue to be inserted. Since the connecting pipe 9 and the rotating ring 10 are threadedly connected, as the connecting pipe 9 continues to fall with the connecting plate 8, the rotating ring 10 will rotate on the outer wall of the connecting pipe 9.

[0049] S3. The Bupleurum seeds are transported to the bottom of the rotating ring 10 by the sowing component. When the connecting plate 8 rises, the sleeve 11 stays inside the soil due to friction between the sleeve 11 and the soil. This causes the connecting plate 8 to drive the connecting pipe 9 and the rotating ring 10 to rise separately, thereby compressing the spring 12. At this time, the actuating rod 13 fixedly connected to the bottom of the sleeve 11 is exposed from inside the rotating ring 10. During the subsequent upward movement, it actuates the soil on the inner wall of the planting hole.

[0050] S4. When the connecting plate 8 drives the connecting pipe 9 and the rotating ring 10 to the position of the fixed rod 14, the top of the rotating ring 10 is pressed by the fixed rod 14. As the connecting pipe 9 drives the rotating ring 10 to continue to rise, the rotating ring 10 rotates around the connecting pipe 9 and moves down to the initial position of the rotating ring 10 and the connecting pipe 9 before drilling and sowing.

[0051] Working principle: When using the perforated seeding equipment and its seeding method for organic Bupleurum chinense planting, the Bupleurum chinense seeds to be planted are put into the feeding device 18. The traction frame 1 is connected to the agricultural tractor. The agricultural tractor drives the traction frame 1 to move, which in turn drives the two sets of rollers 5 to rotate. When the two sets of rollers 5 rotate, the rotation of the two sets of rollers 5 will drive the connecting plate 8 to move forward in a wave-like manner. Through the transmission between the belt 3 and the first synchronous pulley and the second synchronous pulley, the rotating seat 6 is driven to rotate, thereby facilitating the stable movement of the connecting plate 8. During the movement of the connecting plate 8, the perforation component 7 fixedly connected to its bottom moves periodically, thereby achieving the effect of evenly opening holes at equal intervals on the weed control cloth.

[0052] Meanwhile, when the connecting plate 8 moves, it drives the connecting pipe 9 and the rotating ring 10 fixedly connected to its bottom to move. When the rotating ring 10 is inserted into the soil and its upper lower surface is blocked by the soil and cannot fall, since the connecting pipe 9 and the rotating ring 10 are connected by threads, when the connecting pipe 9 continues to descend with the connecting plate 8, the rotating ring 10 rotates in the soil, achieving the effect of loosening the soil. When the connecting plate 8 rises, it drives the connecting pipe 9 to move synchronously. The movement of the connecting pipe 9 drives the rotating ring 10 to move. Due to the friction between the sleeve 11 and the soil, the sleeve 11 stays in the soil. At this time, the rotating ring 10 rises, causing multiple sets of actuating rods 13 fixedly connected at equal angles at the bottom of the sleeve 11 to protrude from the inside of the rotating ring 10. As the rotating ring 10 gradually rises, it gradually agitates the soil on the planting hole wall, thereby covering the Bupleurum seeds with soil. When the sleeve 11 moves to the outside of the soil, it is reset by the spring 12 fixedly connected to its bottom.

[0053] Before the connecting plate 8 rises, the seed metering device 19 takes a corresponding number of Bupleurum seeds from the inside of the feeding device 18 and transports them to the inside of the rotating ring 10 through the hose 16. At this time, the Bupleurum seeds will accumulate at the bottom of the rotating ring 10. Since the opening at the bottom of the rotating ring 10 is small, the Bupleurum seeds will gradually fall off as the rotating ring 10 rises. When the rotating ring 10 rises, the actuating rod 13 will cover the soil on the inner wall of the planting hole with soil at different depths, thereby achieving the effect of sowing Bupleurum seeds at different depths.

[0054] Furthermore, when the connecting plate 8 continues to move, driving the connecting pipe 9 and the rotating ring 10 to the position of the fixed rod 14, the top of the rotating ring 10 is pressed by the fixed rod 14, causing the rotating ring 10 to be subjected to a downward forced starting force and rotate along the thread on the outer wall of the connecting pipe 9. Immediately afterwards, the rotating ring 10 disengages from the fixed rod 14. At this time, the connecting plate 8 continues to move, driving the connecting pipe 9 to continue to move, but the rotating ring 10 will continue to return to its original position downward under the action of the torsion spring.

[0055] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.

A second synchronous wheel is fixedly connected to the central shaft surface of one of the rollers (5) in the same group. The surfaces of the first synchronous wheel and the second synchronous wheel are covered with a belt (3). Rotating seats (6) are fixedly connected to both ends of the rotating shaft of the support plate (2). The two rotating seats (6) are rotatably connected to the side walls of the two connecting plates (8) respectively.

3. The hole-type sowing device for organic Bupleurum cultivation according to claim 1, characterized in that: The punching assembly (7) is installed at the bottom of the connecting plate (8). A heating tube (17) is fixedly connected inside the punching assembly (7). A heating controller (20) is fixedly connected to the top of the traction frame (1). Each heating tube (17) is electrically connected to the heating controller (20) via a wire.

4. The hole-type sowing device for organic Bupleurum cultivation according to claim 1, characterized in that: The bottom of the traction frame (1) is fixedly connected with four fixed rods (14) at equal intervals, and each connecting plate (8) has a groove (15) on one side for making way for the fixed rods (14).

5. A method for planting organic Bupleurum chinense using a perforation-type sowing method, applicable to the perforation-type sowing equipment for planting organic Bupleurum chinense as described in claim 4, characterized in that, The sowing method includes the following steps: S1. The connecting plate (8) is driven to move in a wave-like manner by the rolling of the roller (5). During the downward movement of the connecting plate (8), the weed control cloth is perforated by the perforation assembly (7). S2. Simultaneously, the downward-moving connecting plate (8) will drive the connecting pipe (9) and the rotating ring (10) to insert into the soil. When the lower surface of the upper end of the rotating ring (10) is blocked by the soil, it cannot continue to be inserted. Since the connecting pipe (9) and the rotating ring (10) are threadedly connected, as the connecting pipe (9) continues to fall with the connecting plate (8), the rotating ring (10) will rotate on the outer wall of the connecting pipe (9). S3. The seeds of Bupleurum are transported to the bottom of the rotating ring (10) by the sowing component. When the connecting plate (8) rises, the sleeve (11) stays in the soil due to the friction between the sleeve (11) and the soil. This causes the connecting plate (8) to drive the connecting pipe (9) and the rotating ring (10) to rise separately, thereby compressing the spring (12). At this time, the actuating rod (13) fixedly connected to the bottom of the sleeve (11) is exposed from the inside of the rotating ring (10) and moves the soil on the inner wall of the planting hole during the subsequent upward movement. S4. When the connecting plate (8) drives the connecting pipe (9) and the rotating ring (10) to the position of the fixed rod (14), the top of the rotating ring (10) is pressed by the fixed rod (14). As the connecting pipe (9) drives the rotating ring (10) to continue to rise, the rotating ring (10) rotates around the connecting pipe (9) and moves down to the initial position of the rotating ring (10) and the connecting pipe (9) before drilling and sowing.
