Description

Technical Field

[0001] This invention relates to the field of sowing and fertilization technology, specifically to a dual-variable adjustable sowing and fertilization machine for planting Chinese medicinal herbs. Background Technology

[0002] Chinese medicinal herbs refer to native medicinal materials used under the guidance of traditional Han Chinese medicine. With development, Chinese medicinal herbs have also begun to be cultivated on a large scale. In order to improve the efficiency of cultivation and reduce manual labor, it is necessary to use Chinese medicinal herb sowing and fertilization machines for sowing and planting.

[0003] However, existing seeding and fertilizing machines for planting Chinese medicinal herbs still have certain problems in use: A method for planting and fertilizing medicinal herbs in mountainous areas, as described in Chinese Patent Application No. CN202122263795.3, relates to the field of medicinal herb machinery. This method includes a frame, a walking assembly, a planting assembly, a fertilizing assembly, a power assembly, and an adjuster. The power assembly is mounted on the frame. The walking assembly includes a drive wheel and a driven wheel, both connected to the frame. The drive wheel is connected to the power assembly. The planting and fertilizing assemblies are both connected to the driven wheels. The planting assembly is positioned between the fertilizing assembly and the drive wheel, and the fertilizing assembly is positioned between the planting assembly and the driven wheel. The adjuster includes a fixed sleeve and a furrowing component. The fixed sleeve is fitted over the furrowing component, which can slide relative to the fixed sleeve. The fixed sleeve is fixedly connected to the frame. 1. Although existing medicinal herb sowing and fertilization devices can control the amount of sowing and fertilization, the required planting spacing varies depending on the planting density of different medicinal herbs. However, existing medicinal herb sowing and fertilization devices cannot control the spacing between sowing and fertilization, which limits their use. 2. While existing methods can measure the amount of fertilizer and seeds to be applied at one time, they cannot control and adjust the ratio of medicinal herb seeds and fertilizer separately, resulting in poor applicability.

[0004] To address the aforementioned issues, an innovative design was developed based on the existing dual-variable adjustable seeding and fertilizing machine used for planting Chinese medicinal herbs. Summary of the Invention

[0005] The purpose of this invention is to provide a dual-variable adjustable sowing and fertilizing machine for planting Chinese medicinal herbs, in order to solve the problems mentioned in the background art that existing Chinese medicinal herb sowing and fertilizing devices cannot adjust the sowing and fertilizing spacing, as well as the fertilizer-to-seed ratio, and have a limited range of applications.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a dual-variable adjustable seeding and fertilizing machine for planting Chinese medicinal herbs, comprising a support platform: The lower right side of the support platform is connected to a first support plate, and the lower end of the first support plate is connected to a power roller. The lower left side of the support platform is equipped with a second support plate, and the lower end of the second support plate is connected to a transmission roller. The lower left side of the support platform is provided with a trenching plow, and the upper ends of both sides of the trenching plow are connected to threaded screws, and the upper ends of the threaded screws are connected to the support platform. A soil covering plate is provided at the lower right side of the support platform, and a positioning rod is connected to the left side of the soil covering plate, with both ends of the positioning rod connected to the first support plate. A support frame is fixed at the upper middle part of the support platform, and a feeding box is provided in the middle of the support frame. A feeding hopper is connected to the lower end of the feeding box. An auger shaft is provided inside the feeding hopper, and a transmission connecting rod is connected to the upper end of the auger shaft.

[0007] Preferably, the upper end of the ditching plow is rotatably connected to the threaded screw, and the upper end of the threaded screw is threadedly connected to the support platform. A positioning tube is connected to the left side of the support platform, and a limit rod is slidably connected inside the positioning tube. The bottom end of the limit rod is connected to the ditching plow.

[0008] Using the above technical solution, the furrowing plow can be raised and lowered by rotating the threaded screw, thereby adjusting the height of the furrowing plow and the depth of sowing. Furthermore, the stability of the furrowing plow during raising and lowering can be improved by using the positioning tube and the limiting rod.

[0009] Preferably, the upper left end of the soil covering plate is rotatably connected to the positioning rod, and the upper right end of the soil covering plate is rotatably connected to a first resetter. The upper end of the first resetter is rotatably connected to a mounting base, and the mounting base is fixedly connected to the lower end face of the support platform.

[0010] By adopting the above technical solution, the design of the soil covering plate can cover the sowing furrows after sowing and cover fertilizer and Chinese medicinal seed, while keeping the field flat. The rotatable soil covering plate, together with the design of the first reset device, can avoid the device from being obstructed or bumping due to ground undulations.

[0011] Preferably, the feeding hopper has a funnel-shaped structure design, and the size of the auger shaft is adapted to the lower end of the feeding hopper. The feeding box, feeding hopper, auger shaft and transmission connecting rod are symmetrically distributed on both sides of the left and right central axis of the support platform. The upper middle part of the two sets of feeding boxes is connected to a positioning plate, and the rear end of the positioning plate is connected to a power motor. The lower shaft end of the power motor is connected to the rear transmission connecting rod.

[0012] By adopting the above technical solution, the fertilizer and seeds inside the feeding box can be quantitatively fed through the cooperation of the feeding hopper and the auger shaft.

[0013] Preferably, the upper end of the transmission connecting rod extends to the outside of the feeding box, and the transmission connecting rod is rotatably connected to the feeding box. The section of the transmission connecting rod extending to the outside of the feeding box has a directional structure design, and the square section of the transmission connecting rod is slidably connected to the first pulley. The first pulleys are symmetrically distributed on the upper and lower sides of the square section of the transmission connecting rod, and the opposite sides of the two sets of first pulleys have a tapered design. A first transmission belt connects the front and rear sets of first pulleys.

[0014] By adopting the above technical solution, the synchronous rotation of the two sets of transmission links can be maintained through the cooperation of the first pulley and the first transmission belt, while feeding Chinese medicinal herbs and fertilizers at the same time. The distance between the two sets of first pulleys is adjustable to change the diameter of the contact position between the first transmission belt and the first pulley.

[0015] Preferably, a first bidirectional threaded rod is rotatably connected to the middle of the positioning plate, and the first bidirectional threaded rod is symmetrically distributed on both sides of the left and right central axes of the positioning plate. The upper ends of the two sets of the first bidirectional threaded rods are connected to transmission gears, and the two sets of transmission gears are meshed together. The first bidirectional threaded rod has a transmission plate threaded to both ends. The upper end of the transmission connecting rod passes through the transmission plate, and the upper and lower sets of transmission plates are rotatably connected to the corresponding first pulleys.

[0016] By adopting the above technical solution, by rotating the rear first bidirectional threaded rod, the two sets of transmission gears are used to drive the front and rear transmission plates to move, and the distance between the two sets of first pulleys is adjusted to increase and decrease respectively, thereby adjusting the transmission ratio between the two sets of transmission links.

[0017] Preferably, the outer wall of the rotating shaft is fixedly connected to the limiting plate, the middle part of the feeding tube is designed as a circular structure, and the middle part of the limiting plate is in contact with the inner wall of the feeding tube. The limiting plates are arranged in a ring array around the rotating shaft, and the rotating shaft is rotatably connected to the feeding tube. A feeding cover is provided at the lower end of the feeding tube, and a connecting frame is fixed on the right side of the feeding cover. The upper end of the connecting frame is fixed to the support platform.

[0018] By adopting the above technical solution, the feeding speed of fertilizer and Chinese medicinal seed can be controlled by the cooperation of the rotating shaft and the limiting plate, thereby controlling the sowing spacing to suit different Chinese medicinal plant planting needs. The design of the feeding hood can ensure that the seeds and fertilizer can be concentrated and fed into the sowing furrow.

[0019] Preferably, the feed pipe and the rotating shaft are symmetrically distributed on both sides of the left and right central axes of the support platform, and the near ends of the two sets of rotating shafts extend to the outside of the feed pipe. The near ends of the two sets of rotating shafts are connected to a second pulley. The near ends of the two sets of second pulleys have a tapered structure design. The front end of the rear rotating shaft is connected to a second connecting rod, and the second connecting rod is slidably connected to the front rotating shaft. A power shaft is connected between the two sets of transmission rollers, and a third pulley is connected in the middle of the power shaft. A second transmission belt is connected between the third pulley and the two sets of second pulleys.

[0020] By adopting the above technical solution, through the cooperation of the second pulley, the third pulley and the second transmission belt, the transmission roller can drive the rotation of the feeding mechanism when the device is moving, thereby completing the sowing of fertilizer and seeds.

[0021] Preferably, the feeding pipe is slidably connected to the support platform, the support platform is rotatably connected to a second bidirectional threaded rod, and the two ends of the second bidirectional threaded rod are respectively connected to the external threads of two sets of feeding pipes. The upper end of the second support plate is slidably connected to the support platform, and guide rods are passed through both ends of the second support plate. The two ends of the guide rods are fixedly connected to the support platform. A second resetter is connected to the upper right end of the second support plate, and the right end of the second resetter is connected to the support platform.

[0022] By adopting the above technical solution, the spacing between the two sets of feed tubes can be adjusted through the design of the second bidirectional threaded rod, and the two sets of second pulleys can be driven to move synchronously. By changing the spacing between the two sets of second pulleys, the diameter of their contact position with the second transmission belt can be adjusted, and the transmission ratio can be changed. For suitable transmission, the second support plate can slide at the lower end of the support platform, and the belt can be kept taut by the second resetter.

[0023] Compared with the prior art, the beneficial effects of this invention are: this dual-variable adjustable seeding and fertilizing machine for planting Chinese medicinal herbs... 1. By setting up two independent feeding structures to feed medicinal herb seeds and fertilizers respectively, the feeding amount can be controlled and the feeding uniformity can be ensured. The two feeding structures are linked and rotate synchronously to feed the materials, and the transmission ratio of the two belt structures can be adjusted to change the feeding ratio of fertilizers and medicinal herb seeds.

[0024] 2. The sowing structure is connected to the transmission rollers via a belt structure. The movement of the sowing and fertilizing machine provides power to the sowing structure. This not only allows for adjustment of the transmission ratio between the two to control the sowing spacing, but also ensures that the sowing spacing remains equal at different speeds of the sowing and fertilizing machine.

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

[0028] Please see Figures 1-11This invention provides a technical solution: a dual-variable adjustable seeding and fertilizing machine for planting Chinese medicinal herbs, comprising a support platform 1, a first support plate 2 connected to the lower right side of the support platform 1, and a power roller 3 connected to the lower end of the first support plate 2; a second support plate 4 installed on the lower left side of the support platform 1, and a transmission roller 5 connected to the lower end of the second support plate 4; a furrowing plow 6 disposed on the lower left side of the support platform 1, and threaded screws 9 connected to the upper ends of both sides of the furrowing plow 6, with the upper ends of the threaded screws 9 connected to the support platform 1; the upper end of the furrowing plow 6 is rotatably connected to the threaded screws 9, and the upper end of the threaded screws 9 is connected to the support platform 1. Platform 1 is threadedly connected, and a positioning tube 8 is connected to the left side of the supporting platform 1. A limit rod 7 is slidably connected inside the positioning tube 8, and the bottom end of the limit rod 7 is connected to the furrowing plow 6. The power roller 3 has a built-in hub motor, which can provide the driving power for the sowing and fertilizing machine. When the device moves, the furrowing plow 6 is used to open the sowing furrows to facilitate subsequent sowing. The height of the furrowing plow 6 can be adjusted by the threaded screw 9 to control the opening of sowing furrows of different depths, which is suitable for planting different kinds of Chinese medicinal materials. When the furrowing plow 6 is raised and lowered, the positioning tube 8 and the limit rod 7 can be used to improve its raising and lowering stability.

[0029] A soil covering plate 11 is provided at the lower right end of the support platform 1, and a positioning rod 10 is connected to the left side of the soil covering plate 11. The two ends of the positioning rod 10 are connected to the first support plate 2. The upper left end of the soil covering plate 11 is rotatably connected to the positioning rod 10. The upper right end of the soil covering plate 11 is rotatably connected to the first reset device 12. The upper end of the first reset device 12 is rotatably connected to the mounting base 13, and the mounting base 13 is fixedly connected to the lower end face of the support platform 1. After sowing is completed, the soil covering plate 11 provided at the right end of the support platform 1 is used to backfill the broken soil on both sides of the sowing furrow, and the sowing furrow is smoothed during the movement of the soil covering plate 11. Because the soil covering plate 11 is rotatable, it can rotate upward when passing over uneven ground, thereby avoiding obstruction of movement and bumping.

[0030] A support frame 14 is fixed to the upper middle part of the support platform 1, and a feeding box 15 is set in the middle of the support frame 14. A feeding hopper 16 is connected to the lower end of the feeding box 15. An auger shaft 17 is set inside the feeding hopper 16, and a transmission connecting rod 18 is connected to the upper end of the auger shaft 17. The feeding hopper 16 has a funnel-shaped structure design, and the auger shaft 17 is adapted to the lower end size of the feeding hopper 16. The feeding box 15, feeding hopper 16, auger shaft 17 and transmission connecting rod 18 are symmetrically distributed on both sides of the left and right central axis of the support platform 1. A positioning plate 19 is connected to the upper middle part of the two sets of feeding boxes 15, and a power motor 20 is connected to the rear end of the positioning plate 19. The lower shaft end of the power motor 20 is connected to the rear transmission connecting rod 18. The upper end of the 8 extends to the outside of the feeding box 15, and the transmission connecting rod 18 is rotatably connected to the feeding box 15. The section of the transmission connecting rod 18 extending to the outside of the feeding box 15 has a directional structure design, and the square section of the transmission connecting rod 18 is slidably connected to the first pulley 21. The first pulley 21 is symmetrically distributed on the upper and lower sides of the square section of the transmission connecting rod 18, and the two sets of first pulleys 21 have a tapered design on opposite sides. A first transmission belt 22 is connected between the front and rear sets of first pulleys 21. A first bidirectional threaded rod 24 is rotatably connected to the middle of the positioning plate 19, and the first bidirectional threaded rod 24 is symmetrically distributed on both sides of the left and right central axis of the positioning plate 19. The upper ends of the two sets of first bidirectional threaded rods 24 are connected to transmission gears 25, and the two sets of transmission gears 25 are connected to the upper ends of the two sets of first bidirectional threaded rods 24. Gear 25 meshes with the first bidirectional threaded rod 24, with transmission plates 23 threaded at both ends. The upper end of the transmission connecting rod 18 passes through the transmission plate 23, and the upper and lower sets of transmission plates 23 are rotatably connected to the corresponding first pulleys 21. When sowing is required, the power motor 20 provides power to drive the rear transmission connecting rod 18 to rotate. The rear transmission connecting rod 18 drives the two sets of first pulleys 21 with square sliding connections at the upper end to rotate. The front and rear sets of first pulleys 21 are driven by the first transmission belt 22, keeping the two sets of transmission connecting rods 18 and the auger shaft 17 rotating synchronously, so as to uniformly and quantitatively feed the Chinese medicinal seeds and fertilizers inside the feeding box 15 and the feeding hopper 16. When it is necessary to change the Chinese medicinal seeds and fertilizers, the transmission plates 23 are connected to the transmission plates 24 and the transmission plates 23. When adjusting the feeding ratio of the fertilizer, the rear first bidirectional threaded rod 24 can be rotated, and the transmission gear 25 can be used to make the two sets of first bidirectional threaded rods 24 rotate synchronously in opposite directions. When the first bidirectional threaded rod 24 rotates, the transmission plate 23 can drive the first pulley 21 to move synchronously. Since the first bidirectional threaded rods 24 rotate in opposite directions, when the distance between the two sets of first pulleys 21 driven by the rear first bidirectional threaded rod 24 through the transmission plate 23 increases, the distance between the two sets of first pulleys 21 on the front side decreases, thereby keeping the first transmission belt 22 taut. Since the contact diameter between the front and rear first pulleys 21 and the first transmission belt 22 is different, the transmission ratio also changes accordingly, and thus the feeding ratio of fertilizer and seeds also changes.

[0031] A feeding pipe 26 runs through the middle of the support platform 1, and a rotating shaft 27 is connected inside the feeding pipe 26. A limiting plate 28 is connected to the outer wall of the rotating shaft 27. The outer wall of the rotating shaft 27 is fixedly connected to the limiting plate 28. The middle part of the feeding pipe 26 has a circular structure design, and the middle part of the limiting plate 28 contacts the inner wall of the feeding pipe 26. The limiting plates 28 are arranged in a ring array around the rotating shaft 27, and the rotating shaft 27 is rotatably connected to the feeding pipe 26. A feeding cover 31 is provided at the lower end of the feeding pipe 26, and a connecting frame 30 is fixed to the right side of the feeding cover 31. The upper end of the connecting frame 30 is fixed to the support platform 1. The feeding pipe 26 and the rotating shaft 27 are symmetrically distributed on both sides of the left and right central axes of the support platform 1, and there are two sets of rotating shafts 27. Both ends of the two sets of rotating shafts 27 extend to the outside of the feed pipe 26, and the near ends of the two sets of rotating shafts 27 are connected to second pulleys 32. The near ends of the two sets of second pulleys 32 are designed with a tapered structure. The front end of the rear rotating shaft 27 is connected to a second connecting rod 33, and the second connecting rod 33 is slidably connected to the front rotating shaft 27. A power shaft 34 is connected between the two sets of transmission rollers 5, and a third pulley 35 is connected to the middle of the power shaft 34. A second transmission belt 36 is connected between the third pulley 35 and the two sets of second pulleys 32. The feed pipe 26 is slidably connected to the support platform 1. A second bidirectional threaded rod 29 is rotatably connected inside the support platform 1, and the two ends of the second bidirectional threaded rod 29 are respectively connected to the outside of the two sets of feed pipes 26. The second support plate 4 is threadedly connected to the support platform 1 at its upper end, and guide rods 37 pass through both ends of the second support plate 4. The guide rods 37 are fixedly connected to the support platform 1 at both ends. A second reset device 38 is connected to the upper right side of the second support plate 4, and the right end of the second reset device 38 is connected to the support platform 1. The lower end of the hopper 16 extends to the upper end of the discharge pipe 26. Because the inner wall size of the discharge pipe 26 is larger than the lower end of the hopper 16, the movement of the discharge pipe 26 is not affected. When fertilizer and seeds fall into the discharge pipe 26, the third pulley 35 drives the second pulley 32, the rotating shaft 27 and multiple sets of limiting plates 28 to rotate synchronously using the second transmission belt 36, thereby controlling the fertilizer. The seed is sown at a fixed distance. Because the sowing structure is powered by the transmission roller 5, the sowing spacing can remain constant when the travel distance of the device changes. If the sowing spacing needs to be adjusted, the transmission roller 5 can be lifted before sowing, the second bidirectional threaded rod 29 can be rotated to change the distance between the two sets of feed pipes 26, and the distance between the two sets of second pulleys 32 can be changed. The diameter of the contact position between the second pulley 32 and the second transmission belt 36 can be adjusted. The sowing spacing can be changed by changing the rotation speed of the rotating shaft 27. The second support plate 4 can slide at the lower end of the support platform 1. The position of the second support plate 4 can be adaptively adjusted by the second reset device 38 to keep the second transmission belt 36 taut.
