Description

Technical Field

[0001] This invention relates to the field of agricultural machinery technology, and in particular to a double-row planting mechanism for Salvia miltiorrhiza. Background Technology

[0002] Salvia miltiorrhiza is mostly planted using a ridge planting method. The width and shape of the ridges vary significantly across different planting areas. Some areas have wide ridges that can accommodate double-row staggered planting in a triangular pattern, while others have narrow ridges suitable only for single-row aligned planting. Currently, most commercially available double-row Salvia miltiorrhiza planting machines use a fixed staggered spacing design, with the relative positions of the two rows of planting tubes being fixed assembly structures. Once the machine is assembled, the arrangement cannot be adjusted in real-time according to the width of the field ridges.

[0003] Traditional equipment can only perform double-row staggered planting operations, which has poor versatility. When encountering narrow ridge plots, such as the end of the ridge or the edge of the field, the ridge is often narrower than the conventional ridge. During field operations, the feed pipe is difficult to switch back and forth between staggered and non-staggered planting. When moving to the narrow area of ​​the ridge to place the seedlings, problems such as seedling misalignment are very likely to occur, which cannot meet the above requirements. Summary of the Invention

[0004] To address the aforementioned problems, this invention provides a double-row staggered planting mechanism for Salvia miltiorrhiza, which solves the problem that existing equipment can only perform double-row staggered planting operations in a single manner, has poor versatility, and is prone to seedling misalignment when encountering narrow ridge plots.

[0005] To achieve the purpose of the invention, the technical solution adopted by the present invention is as follows: a double-row staggered planting mechanism for Salvia miltiorrhiza includes a fixed body for connecting agricultural planting equipment, and a drive shaft is rotatably mounted inside the fixed body; the fixed body is provided with a first station and a second station, the first station is located at the end of the fixed body relative to the axis of the drive shaft, and the second station is opened in the middle of the fixed body in the form of a slot; a rotary drive component is fixed on the drive shaft, the rotary drive component corresponds to the second station and can rotate synchronously with the drive shaft; a planting tube is provided at the first station corresponding to the axis of the drive shaft, and another planting tube is provided on the side of the second station corresponding to the drive shaft, so that the two planting tubes are staggered to complete the staggered planting of Salvia miltiorrhiza seedlings; wherein, a pressure-bearing component is fixed on the side planting tube, the pressure-bearing component extends into the second station and forms a compression transmission cooperation with the rotary drive component, so that the rotary drive component drives the planting tube to perform reciprocating linear motion by compressing the pressure-bearing component when rotating; a moving frame is fixed on the outside of the side planting tube, and the fixed body is provided with a moving frame. The outer wall of the second workstation is provided with a through-hole extending to the outside of the fixed body, which limits and guides the movement trajectory of the implantation tube and the motion frame. A reset elastic component is provided between the free end of the motion frame and the outer wall of the fixed body, which drives the motion frame and the implantation tube to automatically reset after the rotary drive releases the pressure on the pressure member. The rotary drive is provided with a receiving groove, one end of which is open facing the pressure member, and the other end extends to the axis of the drive shaft. The receiving groove can receive the implantation tube at the corresponding position when the rotary drive leaves the pressure member, so that the two implantation tubes that were originally misaligned are switched from a misaligned state to a coaxial and collinear state, thereby adapting to the operational needs of different implantation arrangements.

[0006] Preferably, the reset elastic component includes a spring and a guide rod. A limit plate is fixed on the fixed body. An insertion hole is provided on the limit plate. One end of the guide rod is fixedly connected to the free end of the motion frame, and the other end slides through the insertion hole and is fixed with a limit nut. The spring is sleeved on the guide rod, with one end elastically abutting the free end of the motion frame and the other end elastically abutting the limit plate.

[0007] Preferably, the fixing body has a long shaft structure, and the fixing body has a through hole along its own axis for assembling the drive shaft. Bearings are embedded at both ends of the through hole, and the two ends of the drive shaft are rotatably assembled with the bearings. The fixing body has a slot at the position corresponding to the second work station. One side of the slot penetrates the outer wall of the fixing body radially, and the other side is integrally formed with the fixing body to form a connecting part. The guide hole is opened on the connecting part, and the rotary drive component is rotatably housed inside the slot. One end of the pressure-bearing component extends into the slot and forms a pressing transmission cooperation with the rotary drive component.

[0008] Preferably, the rotary drive component is an eccentric cam plate, and the outer end of the cam plate is provided with a rubber cylinder. The rubber cylinder participates in the extrusion action, and the pressure-bearing component is a rubber cylinder that forms an extrusion transmission cooperation with the rotary drive component.

[0009] Preferably, the cylindrical end of the pressure-bearing component is connected to diagonal bracing rods, and the two diagonal bracing rods are inclined upward and connected to the wall of the corresponding movable planting tube.

[0010] Preferably, the top end of the planting tube is connected to a flexible corrugated tube that runs vertically through it, and the diameter of the planting tube is smaller than the width of the receiving groove.

[0011] Preferably, the motion frame is U-shaped, and the width of the rotary drive component is smaller than the width of the U-shaped cavity of the motion frame.

[0012] Preferably, one end of the drive shaft reaches the end of the fixing body where the fixed implantation tube is installed, and the other end is provided with a connecting part extending beyond the other end of the fixing body.

[0013] The advantages of this invention compared to the prior art are: 1. By setting up a fixed body, a first work station, and a second work station, and arranging fixed and movable planting pipes on the fixed body respectively, the two planting pipes can flexibly switch between staggered and collinear arrangement according to the width of the ridge. This solves the problem that the planting pipes of traditional Salvia miltiorrhiza planting mechanisms have fixed relative positions and can only adapt to a single planting condition. It realizes the equipment's adaptability to multiple conditions such as double-row staggered planting on wide ridges and single-row collinear planting on narrow ridges, greatly expanding the field application range of the equipment.

[0014] 2. By setting up a drive shaft and a rotary drive component, the drive shaft drives the rotary drive component to rotate synchronously to form a compression transmission cooperation, controlling the compression state of the compressed component, realizing rapid, tool-free mechanical linkage switching between two planting modes in field operation, and improving the efficiency of mechanized planting operations.

[0015] 3. By setting guide holes and limiting guide structures for the motion frame, the movable planting tube is constrained to only make vertical reciprocating motion, effectively avoiding deviation, shaking and jamming during the adjustment and operation of the planting tube.

[0016] 4. By setting an open receiving groove on the rotating drive component that extends to the axis of the drive shaft, the planting tubes of the two stations can smoothly and accurately switch between staggered double-row planting and single-row aligned planting modes, adapting to the clearance space when switching between narrow and wide ridges, and meeting the diverse agronomic planting needs of Salvia miltiorrhiza.

[0019] The above and other embodiments and advantages 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.

[0020] like Figures 1-7As shown, this embodiment provides a double-row staggered planting mechanism for Salvia miltiorrhiza, including a fixed body 1 for connecting agricultural planting equipment, with a drive shaft 2 rotatably mounted inside; the fixed body 1 is provided with a first station 3 and a second station 3A. The first station 3 is located at the end of the fixed body 1 relative to the axis of the drive shaft 2, and the second station 3A is opened in the middle of the fixed body 1 in the form of a slot. A rotary drive component 4 is fixed on the drive shaft 2, and the rotary drive component 4 corresponds to the second station 3A and can rotate synchronously with the drive shaft 2; the first station 3 is provided with a planting tube 5 (i.e., a fixed planting tube 52) corresponding to the axis of the drive shaft 2, and the second station 3A is provided with another planting tube 5 (i.e., a movable planting tube 53) on the side of the drive shaft 2. In this way, the two planting tubes 5 are staggered to complete the staggered planting of Salvia miltiorrhiza seedlings. A pressure-receiving component 6 is fixedly installed on the movable planting tube 53. The pressure-receiving component 6 extends into the second station 3A and forms a compression transmission cooperation with the rotary drive component 4, so that the rotary drive component 4 drives the movable planting tube 53 to reciprocate linear motion by squeezing the pressure-receiving component 6 when rotating. A motion frame 7 is fixed to the outside of the movable implantation tube 53. A guide hole 8 is provided on the outer wall of the fixed body 1 corresponding to the second station 3A, which runs through the inside and outside. The motion frame 7 extends through the guide hole 8 to the outside of the fixed body 1, and is used to limit and guide the movement trajectory of the movable implantation tube 53 and the motion frame 7. A reset elastic component 9 is provided between the inner wall of the free end of the motion frame 7 and the outer wall of the fixed body 1, which is used to drive the motion frame 7 and the movable implantation tube 53 to automatically reset after the rotation drive 4 releases the pressure on the pressure member 6. The rotary drive 4 is provided with a receiving groove 10. One end of the receiving groove 10 facing the pressure member 6 is open, and the other end extends to the axis of the drive shaft 2. When the rotary drive 4 leaves the pressure member 6, the receiving groove 10 can accommodate the movable planting tube 53, so that the two planting tubes 5 that were originally staggered can be switched from a staggered state to a coaxial and collinear state, thereby adapting to the operational needs of different planting arrangements.

[0021] It should be noted that during use, the fixed body 1 of this planting mechanism is first assembled and fixed onto the agricultural planting equipment at the end furthest from the first workstation 3, completing the overall machine positioning and installation. During operation, the entire mechanism can move synchronously, connecting the two planting tubes 5 to the disc-type seedling emergence mechanism on the agricultural planting equipment. The working power of the mechanism is provided by the drive shaft 2, which is rotatably assembled inside the fixed body 1. It can continuously rotate at a uniform speed under the drive of an external power structure (such as an electrically controlled motor control mechanism or a manually controlled lever mechanism, the other end of which is connected to the relevant components or electrical control system of the control room of the agricultural planting equipment, which is existing technology and will not be described in detail). This drives the rotary drive component 4 fixed on the shaft to rotate synchronously and coaxially, providing the core power input for the reciprocating planting action of the entire planting mechanism.

[0022] This mechanism achieves a double-row staggered planting layout by setting up a first station 3 and a second station 3A on the fixed body 1. The first station 3 is located at the end of the fixed body 1 and corresponds to the axis of the drive shaft 2. The second station 3A is a slotted structure opened in the middle of the fixed body 1. Each station is equipped with a planting tube 5, so that the two planting tubes 5 form a staggered arrangement structure in the initial state, which meets the basic arrangement requirements of the staggered planting of Salvia miltiorrhiza in a triangular shape. The fixed planting tube 52 corresponding to the first station 3 is fixedly arranged along the axis of the drive shaft 2 and remains fixed during operation, only undertaking the fixed-point seedling placement operation; the movable planting tube 53 corresponding to the second station 3A can be adjusted to a coaxial (or nearly coaxial) position with the movable planting tube 53 under special circumstances, so that two ginseng seedlings are planted in the same row.

[0023] The adjustment principle of the planting tube 5 in the second workstation 3A is as follows: When the equipment is positioned where the width of the ridge is suitable for planting two rows of ginseng seedlings, the drive shaft 2 drives the rotating drive component 4 to rotate, causing the eccentric end of the rotating drive component 4 to form a compression transmission relationship with the pressure component 6. This forces the pressure component 6 to push the movable planting tube 53 and the fixed planting tube 52 to maintain a staggered relationship. At this time, the moving frame 7 moves away from the fixed body 1, and the reset elastic component 9 is compressed and tightened and stores elastic force. The two planting tubes 5 are in a staggered position, which, together with the double-tube seedling emergence mechanism of the agricultural planting equipment, completes the planting of two ginseng seedlings. Double-row planting; when the equipment moves to a planting area with a narrower ridge, the ridge width is no longer sufficient for planting two rows of ginseng seedlings. The control drive shaft 2 drives the rotating drive component 4 to rotate in the opposite direction, so that the eccentric end of the rotating drive component 4 gradually separates from the pressure component 6. The squeezing force on the pressure component 6 gradually decreases, and the reset elastic component 9 releases its elastic force and becomes longer, pushing the motion frame 7 to drag the movable planting tube 53 in a straight line. This allows the movable planting tube 53 and the fixed planting tube 52 to be in a coaxial (or nearly coaxial) position, cooperating with the double-tube seedling emergence mechanism of the agricultural planting equipment to complete the single-row planting of two ginseng seedlings.

[0024] The further explanation of "planting pipe 5 corresponding to the second work station 3A under special circumstances" is as follows: In special working conditions in the field, such as the end section of the plot, the area where the ridge is collapsed or damaged, the transition area between wide and narrow ridges, the area where narrow ridges are repaired, and other non-standard planting areas, the effective planting width of the ridge is greatly reduced, which cannot meet the agronomic space requirements of double-row staggered planting. If double-row planting is continued, problems such as seedlings being planted off-center, insufficient soil covering, exposed roots, and seedlings falling over and dying will easily occur. At this time, the movable planting pipe 53 corresponding to the second work station 3A can be adjusted to a position coaxial or approximately colinear with the fixed planting pipe 52, and switched to a single-row aligned planting mode to adapt to the planting space of the narrow ridge.

[0025] During the movement of the movable implantation tube 53, precise positioning and guidance are achieved through the movement frame 7 fixed on the outside and the guide hole 8 on the outer wall of the fixed body 1. The movement frame 7 extends through the guide hole 8 to the outside of the fixed body 1. The guide hole 8 can strictly constrain the movement trajectory of the movable implantation tube 53, so that it can only make straight reciprocating movements in the vertical direction, effectively avoiding the problems of deviation, shaking, and jamming during the adjustment of the movable implantation tube 53.

[0026] Meanwhile, the rotary drive component 4 has a specially structured receiving groove 10. One end of the receiving groove 10 facing the pressure-bearing component 6 is open, while the other end extends to the axis of the drive shaft 2. When the equipment needs to adapt to a single-row planting arrangement on raised beds or eliminate the staggered planting mode, the angle of the rotary drive component 4 can be adjusted so that the receiving groove 10 faces the pressure-bearing component 6 and the movable planting tube 53. When the rotary drive component 4 rotates to this position, the receiving groove 10 can completely accommodate the movable planting tube 5 at the corresponding position, making the two originally staggered planting tubes 5 basically coaxially aligned, smoothly switching from the staggered planting state to the coaxial and collinear planting state. Through this structural switching, the mechanism can flexibly adapt to different agronomical operation requirements such as staggered planting of Salvia miltiorrhiza and aligned double-row planting, greatly improving the versatility and adaptability of the mechanism.

[0027] In summary, this mechanism relies on a single-drive shaft linkage rotary drive structure, combined with extrusion transmission, guide limit and elastic reset structure, to achieve stable staggered alternating planting of double-row planting tubes. At the same time, the planting mode can be switched through the storage structure of the receiving trough 10. The overall structure has strong linkage and precise and stable operation. It can efficiently complete the mechanized planting operation of Salvia miltiorrhiza without the need for complex electrical control and hydraulic structures.

[0028] Specifically, the reset elastic component 9 includes a spring 91 and a guide rod 92. A limit plate 101 is fixed on the fixed body 1. The limit plate 101 has an insertion hole 102. One end of the guide rod 92 is fixedly connected to the free end of the motion frame 7, and the other end slides through the insertion hole 102 and is fixed with a limit nut. The spring 91 is sleeved on the guide rod 92, with one end elastically abutting against the free end of the motion frame 7 and the other end elastically abutting against the limit plate 101.

[0029] When the rotating drive 4 presses against the pressure-bearing component 6 and drives the movable implantation tube 53 and the motion frame 7 to move outward, the motion frame 7 slides along the guide rod 92 axially and compresses the spring 91, causing the spring 91 to undergo elastic compression deformation and store elastic potential energy. When the rotating drive 4 rotates with the drive shaft 2 and disengages from the pressure-bearing component 6, and the pressing force is gradually released, the spring 91 releases its stored elastic potential energy and pushes the motion frame 7 to precisely slide back along the guide rod 92 axially, thereby driving the movable implantation tube 53 to automatically reset and realize the collinear alignment switching of the two implantation tubes 5.

[0030] Specifically, the fixed body 1 has a long shaft structure. The fixed body 1 has a through hole for assembling the drive shaft 2 along its own axis. Bearings are embedded at both ends of the through hole, and the two ends of the drive shaft 2 are rotatably assembled with the bearings. The fixed body 1 has a slot 3A1 at the position corresponding to the second station 3A. One side of the slot 3A1 penetrates the outer wall of the fixed body 1 radially, and the other side is integrally formed with the fixed body 1 with a connecting part 3A2. The guide hole 8 is opened on the connecting part 3A2. The rotary drive 4 is rotatably housed inside the slot 3A1. One end of the pressure member 6 extends into the slot 3A1 and forms a pressing transmission cooperation with the rotary drive 4.

[0031] The fixed body 1 serves as the assembly base. A through hole is formed along the fixed body 1's axis to accommodate the drive shaft 2. To reduce frictional resistance during high-speed rotation of the drive shaft 2 and ensure its coaxiality and operational stability, bearings are embedded at both ends of the through hole. The two ends of the drive shaft 2 are connected to the inner rings of the two bearings, allowing the drive shaft 2 to rotate smoothly and stably relative to the fixed body 1 around its own axis, effectively avoiding problems such as jamming and wear. The slot 3A1 is the core assembly area of ​​the second workstation 3A. One side of the slot 3A1 radially penetrates the outer wall of the fixed body 1, forming an open installation space for easy assembly and maintenance of the rotating drive component 4 and the pressure-bearing component 6. The other side of the slot 3A1 is integrally formed with the fixed body 1 body via a connecting part 3A2. This connecting part 3A2 achieves a rigid connection between the slot area and the fixed body 1 body, ensuring overall structural strength and preventing structural deformation and insufficient rigidity of the fixed body 1 after slotting. The guide hole 8 is opened on the connecting part 3A2. The rotary drive component 4 is fully housed and assembled in the internal space of the slot 3A1. It can rotate with the drive shaft 2 inside the slot 3A1 without interference. One end of the pressure member 6 on the movable implant tube 53 extends into the inside of the slot 3A1, forming a stable extrusion transmission cooperation structure with the rotary drive component 4 in the slot. This provides a stable structural foundation for the reciprocating linear motion of the movable implant tube 53 and the switching between staggered and collinear modes.

[0032] Specifically, the rotary drive component 4 is an eccentric cam plate, and the outer end of the cam plate is provided with a rubber cylinder. The rubber cylinder participates in the extrusion action, and the pressure-bearing component 6 is a rubber cylinder that forms an extrusion transmission cooperation with the rotary drive component 4.

[0033] The rotary drive component 4 is an eccentric cam plate with a rubber cylinder at its outer end. The rubber cylinder is fixedly mounted on the drive shaft 2 in the form of participating in the extrusion action and can rotate synchronously and coaxially with the drive shaft 2. The whole assembly is housed in the internal space of the slot 3A1. Correspondingly, the pressure-bearing component 6 is a rubber cylinder structure, fixed at the corresponding position of the movable planting tube 53, with one end extending into the slot 3A1. It always keeps in close contact with the eccentric cam plate, the outer end of which is provided with a rubber cylinder, and the outer contour surface of the rubber cylinder participating in the extrusion action. Relying on the eccentric cam plate, the outer end of the cam plate is provided with a rubber cylinder. The contour characteristics of the rubber cylinder participate in the extrusion action, and it can generate continuous radial displacement changes during continuous rotation, which stabilizes the pressure-bearing component 6 of the rubber cylinder material. Under normal conditions, it ensures that the movable implantation tube 53 and the fixed implantation tube 52 are misaligned. The rubber cylinder characteristics of the pressure-bearing component 6 have a certain elastic buffering performance, which can effectively weaken the rigid impact during the cam rotation extrusion process, reduce operating noise and component wear, and avoid jamming and loosening problems caused by hard metal contact.

[0034] Specifically, the two ends of the cylindrical part 6 of the pressure-bearing component 6 are connected to the diagonal bracing rods 61. The two diagonal bracing rods 61 are inclined upward and connected to the wall of the corresponding planting tube 5 (movable). The diagonal bracing rods 61 extend the support distance and transmit the extrusion force on the pressure-bearing component 6 to the movable planting tube 53, so that the movable planting tube 5 and the fixed planting tube 52 are misaligned.

[0035] Specifically, the top of the planting tube 5 is connected to a flexible corrugated pipe 51 that runs vertically through it, and the diameter of the planting tube 5 is smaller than the width of the receiving groove 10. The flexible corrugated pipe 51 is designed to run vertically through it, with the upper end connecting to the seedling dispensing mechanism of the equipment and the lower end connecting to the internal channel of the planting tube 5. It can reciprocate linearly and switch positions with the planting tube 5, adapting to the position changes of the planting tube 5 through its own flexible expansion and contraction characteristics. This ensures smooth seedling placement and avoids problems such as detachment, cracking, and seedling blockage caused by displacement and pulling of rigid pipe connections. The diameter of the planting tube 5 is smaller than the width of the receiving groove 10 on the rotating drive component 4, so that when the movable planting tube 5 switches to a state close to coaxial with the fixed planting tube 5, it can smoothly extend into the receiving groove 10 for storage and avoidance, without structural jamming or interference.

[0036] Specifically, the motion frame 7 is U-shaped, and the width of the rotary drive component 4 is smaller than the width of the U-shaped cavity of the motion frame 7. When the rotary drive component 4 rotates downward, it can enter the U-shaped cavity space of the motion frame 7, increasing the rotation amplitude of the rotary drive component 4. This causes the cam surface of the rotary drive component 4 to press against the pressure receiving component 6, and causes the pressure receiving component 6 to push the movable planting tube 53 and the fixed planting tube 52 to a greater degree of misalignment through the diagonal brace 61, ensuring the misalignment relationship of the two planting tubes 5.

[0037] Specifically, one end of the drive shaft 2 reaches the end of the fixing body 1 where the implantation tube 5 is installed, and the other end is provided with a drive extension 21 that extends beyond the other end of the fixing body 1.

[0038] The drive extension 21 serves as the power input docking end for the entire machine, allowing direct assembly and docking with the power drive or mechanical transmission components of the planting equipment. The power input end of this mechanism utilizes existing agricultural machinery intelligent drive technology to achieve automated and intelligent operation control. In actual assembly and use, the drive extension 21 can be connected to the output end of the equipment's drive motor via a coupling, transmission sprocket, or gear set. The equipment's electronic control system (located in the driver's cab of the planting equipment) can remotely control the start, stop, forward, and reverse rotation of the drive motor, thereby controlling the rotation direction of the drive shaft 2 via the coupling, achieving the staggered transformation between the movable planting tube 53 and the fixed planting tube 52. The specific electronic control motor drive components that can be docked with are mature existing technologies, requiring no modification to their structure.
