Description

Technical Field

[0001] The present invention relates to the technical field of Chinese herbal medicine transplanting equipment, and specifically refers to a Chinese herbal medicine rhizome non-destructive batch transplanting equipment. Background Art

[0002] In the field of Chinese herbal medicine planting, the transplanting quality of rhizome herbs such as Astragalus membranaceus and Salvia miltiorrhiza directly affects their survival rate and yield.

[0003] Traditional manual transplanting methods rely on manual digging of pits, placing, and covering with soil. Not only is the labor intensity high and the efficiency low, but it is also difficult to accurately control the placement posture of the rhizomes. Vertical planting easily causes rhizome bending and epidermal abrasion, severely restricting large-scale planting. Although existing mechanized equipment attempts to improve efficiency, it generally has structural defects: transplanting mechanisms mostly adopt vertical feeding, and cannot achieve horizontal placement transplanting that conforms to the horizontal growth characteristics of rhizomes; there is a lack of coordinated design in the processes of pit digging, transplanting, and soil covering, and the process connection is inefficient; the power system relies on traditional crank-link mechanisms or multi-motor separate control, which occupies a large space, has high transmission losses, and is prone to positioning deviation due to long-term wear; the clamping mechanism has poor adaptability to irregular rhizomes such as ginseng fibrous roots and Astragalus membranaceus, and rigid clamping results in a high damage rate. The transfer and compaction of soil clods in the land preparation link still require manual assistance, and it is difficult to ensure the uniformity of soil pit specifications and the quality of backfilling.

[0013] The beneficial effects of the present invention compared with the prior art are as follows: The soil spreading mechanism digs pits, the placing mechanism feeds materials, the picking and placing mechanism transplants, and the power mechanism drives, forming an integrated flow operation mode of digging pits, transplanting, and covering soil. The linkage between the rounded rectangle guide groove and the sliding groove in the picking and placing mechanism, through a unique rounded rectangle trajectory, eliminates the impact of mechanical sudden stops and vibrations on the rhizomes, realizes a "human-like hand" flexible transplanting action, ensures the damage-free transplanting of medicinal materials. At the same time, it realizes the flat planting of medicinal materials, which conforms to the growth characteristics of many rhizome Chinese medicinal materials such as astragalus membranaceus and salvia miltiorrhiza. Compared with traditional vertical planting, it can effectively avoid rhizome bending or epidermal abrasion, greatly reducing the damage rate, providing good initial growth conditions for medicinal materials, being beneficial to improving the survival rate and quality of medicinal materials, and greatly improving the efficiency and quality of batch transplanting of Chinese medicinal materials. Specifically:

[0014] 1. The vertical layout of the positioning sliding groove and the limit sliding groove converts the rotation of the picking and placing motor into a linear motion of the rack, reducing space occupation and improving space utilization efficiency. The high-speed rotation of the picking and placing motor is decelerated in two stages by the "slider-rack", outputting a stable low-frequency and high-torque rotation, which can accurately control the reciprocating rotation angle of the picking and placing rotating column, avoiding the shedding of the rhizomes of Chinese medicinal materials or positioning deviation caused by too fast transplanting actions, and effectively ensuring the accuracy and stability of the transplanting operation;

[0015] 2. The ingenious combination of the L-shaped clamping frame and the double-adjustable connecting rod effectively amplifies the thrust of the push rod using the lever principle, ensuring a very high synchronization of the closing of the bilateral clamping plates, avoiding rhizome deviation or fracture caused by unilateral pressure, greatly improving the clamping stability. During the clamping process, from wrapped clamping to gentle opening after transplanting, the risk of mechanical hard friction or bending is avoided throughout the process, providing a reliable guarantee for the damage-free transplanting of Chinese medicinal materials, and greatly improving the quality and efficiency of the transplanting operation;

[0016] 3. The second electric push rod can accurately adjust the height of the soil spreading motor and the ditch-opening component to adapt to different land conditions, efficiently complete the ditch-opening operation, greatly improving the adaptability and ditch-opening efficiency of the operation. The transfer mechanism realizes a smooth connection from soil picking, soil spreading to soil delivery through the coordinated operation of transfer rollers, conversion rollers, reciprocating screws, guide frames, soil spreading plates, etc., improving the soil spreading efficiency, greatly shortening the land preparation time, and winning valuable time for the subsequent transplanting work. By using the power of the ditch-opening sleeve to drive the transfer mechanism, the setting of additional power sources is reduced, effectively reducing energy consumption, conforming to the concept of energy conservation and environmental protection. The coordinated design of the inclined transfer pipe and the soil pressing plate stably and effectively compacts the backfilled soil, making the soil closely fit the ditch-opening area, significantly reducing the risk of rhizome displacement after transplanting, and effectively improving the stability and survival rate of transplanting, comprehensively ensuring the high-quality completion of the land preparation work before Chinese medicinal material transplanting;

[0017] 4. The position of the placement plate on the placement rack can be conveniently adjusted by the adjusting nut. Whether it is Chinese herbal medicines with slender rhizomes or those with tuberous rhizomes, the appropriate placement height can be found, easily meeting the placement requirements of various Chinese herbal medicines of different sizes, greatly enhancing the adaptability of the equipment to diverse Chinese herbal medicines. The reciprocating rack, reciprocating rod, supporting top block, positioning rotating plate, upper blanking plate, and lower blanking plate cooperate to achieve the single and orderly movement of Chinese herbal medicines, effectively preventing the phenomenon of multiple or misaligned materials, laying a solid foundation for subsequent precise transplanting, ensuring that each Chinese herbal medicine can accurately enter the transplanting link according to the predetermined process. In cooperation with the spring, limiting plate, cooperating sliding plate, retaining rack, and retaining rotating plate, while the Chinese herbal medicines move individually, the retaining rotating plate can be timely opened, enabling the clamping mechanism to clamp smoothly, enhancing the coherence and automation level of the equipment operation, reducing manual intervention, improving production efficiency, and providing strong support for the efficient operation of the Chinese herbal medicine rhizome non-destructive batch transplanting equipment.

[0033] The present invention will be further described in detail below with reference to the accompanying drawings.

[0034] Combined with the attached Figure 1 、attached Figure 2 、attached Figure 3 、attached Figure 4 、attached Figure 5 and attached Figure 14As shown in the figure, a device for batch transplanting traditional Chinese medicine roots and rhizomes without damage includes a frame 1. A placing mechanism 2 for placing traditional Chinese medicine and a soil spreading mechanism 5 for digging pits in the soil are provided on the frame 1. A picking and placing mechanism 3 for horizontally transplanting the traditional Chinese medicine placed on the placing mechanism 2 is provided on the frame 1. The picking and placing mechanism 3 includes a guide plate 11 provided on the frame 1. A guide groove 111 is provided on the guide plate 11. The guide groove 111 is a rounded rectangle structure. A picking and placing plate 321 is slidably provided on the guide groove 111. A connecting block 32 is rotatably provided on the guide plate 11. The picking and placing plate 321 slidably passes through the connecting block 32. A graphene-coated slider is embedded in the contact surface between the guide groove 111 and the picking and placing plate 321 to reduce wear deviation. A clamping mechanism 4 for clamping the traditional Chinese medicine is provided on the picking and placing plate 321. A picking and placing rotating column 31 is rotatably provided on the guide plate 11. A picking and placing chute 311 slidably engaged with the picking and placing plate 321 is provided at one end of the picking and placing rotating column 31. A power mechanism for driving the picking and placing rotating column 31 to reciprocally rotate is provided on the frame 1.

[0035] The working principle of the present invention is as follows: First, the soil spreading mechanism 5 digs standardized soil pits in the soil. At the same time, the placing mechanism 2 transports the roots and rhizomes of traditional Chinese medicine to the picking and placing station in sequence. Then, the power mechanism drives the picking and placing rotating column 31 to reciprocally rotate. Through the sliding cooperation between the picking and placing chute 311 at the end of the picking and placing rotating column 31 and the picking and placing plate 321, the movement of the picking and placing plate 321 along the rounded rectangle path of the guide groove 111 is forcibly constrained, forming a continuous action chain of "grasping - transferring - releasing". The clamping mechanism 4 grasps the roots and rhizomes of traditional Chinese medicine during the movement of the picking and placing plate 321. Through the smooth turning characteristics of the rounded rectangle trajectory, the roots and rhizomes are gently embedded in the soil pits in a horizontal posture, avoiding the root bending or epidermal abrasion caused by traditional vertical planting. After completing the transplanting of a single plant, the picking and placing plate 321 automatically resets along the trajectory, and the soil spreading mechanism 5 simultaneously covers the soil and compacts it, forming an integrated assembly line operation of digging pits, transplanting, and covering the soil;

[0036] The rounded rectangle guide groove 111 is linked with the chute. By replacing the traditional straight line or right angle turning path with a rounded rectangle trajectory, the impact on the roots and rhizomes caused by mechanical sudden stops and jitters is eliminated. Combined with the sliding cooperation of the picking and placing chute 311, a flexible transplanting action similar to that of a human hand is realized, reducing the damage rate. The picking and placing rotating column 31 converts the rotational motion into the "translation - turning" compound motion of the picking and placing plate 321.

[0037] Combined with attached Figure 3 、attached Figure 4 、attached Figure 5 and attached Figure 6As shown in the figure, the power mechanism includes a pick-and-place motor 34 disposed on the frame 1. A positioning plate 341 is provided at the output end of the pick-and-place motor 34. A positioning slider 342 is provided at one end of the positioning plate 341. A limiting chute 33 is provided on the frame 1. A reciprocating rack 331 is slidably disposed in the limiting chute 33. A pick-and-place gear 312 meshing with the reciprocating rack 331 is provided at one end of the pick-and-place rotating column 31. A positioning chute 337 slidably mating with the positioning slider 342 is provided on the reciprocating rack 331. The contact surface between the positioning slider 342 and the positioning chute 337 is coated with polytetrafluoroethylene to reduce frictional resistance and automatically compensate for wear clearance, ensuring the stability of long-term operation. The positioning chute 337 and the limiting chute 33 are perpendicularly arranged.

[0038] Working principle of the power mechanism: After the pick-and-place motor 34 is started, it drives the positioning plate 341 at the output end to rotate. The positioning slider 342 at the end of the positioning plate 341 slides along the positioning chute 337 on the reciprocating rack 331. Since the positioning chute 337 and the limiting chute 33 are in a vertically intersecting layout, the sliding of the positioning slider 342 is forced to be a horizontal linear motion, pushing the reciprocating rack 331 to reciprocate horizontally in the limiting chute 33. The reciprocating rack 331 meshes with the pick-and-place gear 312, converting the linear motion into an accurate angular reciprocating rotation of the pick-and-place rotating column 31. The rotation of the pick-and-place rotating column 31 drives the pick-and-place plate 321 to move along the rounded rectangular trajectory of the guiding chute 111 through the pick-and-place chute 311, finally realizing the cycle of grasping, laying flat, and releasing of the clamping mechanism 4.

[0039] This is one form of the power mechanism. To achieve the reciprocating sliding of the reciprocating rack 331 and drive the reciprocating rotation of the pick-and-place gear 312 meshing with it through the reciprocating rack 331, a cylinder or a push rod driven by other power can be used to drive it. Further, the output end of the pick-and-place motor 34 can be directly connected to the pick-and-place gear 312, and then the purpose of driving the reciprocating rack 331 to reciprocate by changing the rotation direction of the pick-and-place motor 34 can be achieved.

[0040] Combined with attached Figure 3 、attached Figure 5 and attached Figure 7 As shown in the figure, the clamping mechanism 4 includes a clamping seat 41 disposed on the lower side of the pick-and-place plate 321. Clamping brackets 42 are symmetrically rotatably provided on the clamping seat 41. The clamping brackets 42 are L-shaped structures. Clamping plates 421 are provided on the clamping brackets 42. Silicone or polyurethane elastic materials are provided on the inner sides of the clamping plates 421. Adjusting connecting rods 43 are rotatably provided on the clamping brackets 42. A first electric push rod 322 is provided on the lower side of the pick-and-place plate 321. A synchronous plate 44 is provided at the telescopic end of the first electric push rod 322. A synchronous block 441 rotatably connected to the adjusting connecting rod 43 is provided on the synchronous plate 44.

[0041] Working principle of the clamping mechanism 4: The first electric push rod 322 retracts upward, pushing the synchronization plate 44 and the synchronization block 441 to move vertically. The synchronization block 441 drives the two L-shaped clamping brackets 42 on both sides to rotate symmetrically around the clamping seat 41 through the adjusting connecting rod 43, so that the clamping plates 421 at the ends of the clamping brackets 42 are synchronously closed from the open state, forming a wrapped clamping of the rhizome. The elastic material inside the clamping plate 421 can adapt to the surface shape of the rhizome and evenly disperse the clamping force. After transplanting in place, the electric push rod extends, reversely driving the clamping plate 421 to slowly open, and the rhizome naturally falls into the soil pit, without the risk of mechanical hard friction or bending throughout the process;

[0042] The L-shaped clamping bracket 42 is combined with the double-adjusting connecting rod 43 structure, which amplifies the thrust of the push rod through the lever principle to ensure the synchronism of the bilateral clamping plates 421 (deviation < 0.5 mm), avoiding the rhizome offset or fracture caused by unilateral pressure. The silicone or polyurethane elastic layer inside the clamping plate 421 can fit irregular rhizome shapes such as bending and forking (such as ginseng fibrous roots), reducing the damage rate to less than 0.3%. The first electric push rod 322 directly drives the stroke of the synchronization plate 44, and the clamping opening and closing speed and strength can be programmed and adjusted to adapt to the hardness requirements of different medicinal materials (such as tough astragalus).

[0043] Combined with attached Figure 3 、attached Figure 8 、attached Figure 9 、attached Figure 10 and attached Figure 11 As shown in attached

[0044] 、attached

[0045] Working principle of the soil spreading mechanism 5: When the equipment starts the soil spreading operation, the second electric push rod 512 is activated, pushing the soil spreading slider 511 to slide within the soil spreading support 51, thereby adjusting the height of the trench opening sleeve 52 and related components. Then, the soil spreading motor 513 operates, and its output end drives the trench opening sleeve 52 to rotate. The trench opening claws 521 on the trench opening sleeve 52 rotate accordingly to conduct trench opening operation on the land;

[0046] While conducting the trench opening, the trench opening sleeve 52 drives the conversion roller 543 to rotate. The conversion roller 543 cooperates with the transfer roller 541 to drive the transfer roller 541 to rotate. The reciprocating screw 542 on the transfer roller 541 rotates accordingly. Since the guide frame 545 cooperates with the reciprocating screw 542 and slides on the guide slide rod 544, the rotation of the reciprocating screw 542 drives the guide frame 545 to perform reciprocating linear motion along the guide slide rod 544. During the movement of the guide frame 545, under the action of the one-way rod 547, when the guide frame 545 moves towards the soil collection groove 53 side, the soil pushing plate 546 pushes the soil in the soil collection groove 53 towards the transfer pipe 531 direction. The soil is conveyed to the trench opening through the inclined transfer pipe 531. At the same time, the soil pressing plate 532 sleeved on the transfer pipe 531 will compact the conveyed soil, completing a series of soil spreading operation processes including trench opening, soil extraction, soil transfer, and soil compaction;

[0047] The second electric push rod 512 can flexibly adjust the height of the soil spreading motor 513 and the trench opening components, efficiently completing the trench opening. Each component of the transfer mechanism 5 operates in coordination, greatly improving the soil spreading efficiency and shortening the land preparation time. The reciprocating screw 542 cooperates with the guide frame 545 to precisely control the movement of the soil pushing plate 546, ensuring a stable amount of soil pushed each time and uniform soil filling and compaction. At the same time, by driving the transfer mechanism 54 with the power of the trench opening sleeve 52, additional power sources are reduced, and energy consumption is lowered. The inclined transfer pipe 531 and the soil pressing plate 532 cooperate to stably and effectively compact the backfilled soil, closely fitting the trench opening, reducing the risk of root displacement, and improving the transplanting stability and survival rate.

[0048] Combined with the attached Figure 3 、attached Figure 5 、attached Figure 6 、attached Figure 12 and attached Figure 13 As shown in, the placement mechanism 2 includes a placement rack 21 provided on one side of the frame 1. A placement plate 22 is slidably provided on the placement rack 21. An adjusting nut 221 is movably connected to the placement plate 22 through threads. A material blocking rotating plate 24 is rotatably provided at the lower end of the placement plate 22. A material blocking gear 241 is provided on the material blocking rotating plate 24. A material blocking rack 242 meshing with the material blocking gear 241 is slidably provided on the placement plate 22. The material blocking rack 242 is driven to slide by the reciprocating rack 331;

[0049] One side of the placement rack 21 is rotatably provided with a positioning rotating plate 23. A blanking upper plate 231 is provided on the positioning rotating plate 23. A blanking lower plate 232 is slidably sleeved on the positioning rotating plate 23. Stop bars for blocking the movement of traditional Chinese medicinal materials are provided on both the blanking upper plate 231 and the blanking lower plate 232. A positioning bolt 234 is connected to the blanking lower plate 232 by a thread. A blanking lever 233 is provided on the blanking lower plate 232. The reciprocating rack 331 drives the positioning rotating plate 23 to rotate through the blanking lever 233. A reciprocating rod 332 is provided on the reciprocating rack 331. A mating slide plate 334 connected to the material blocking rack 242 is slidably provided on the reciprocating rod 332. A mating spring 335 is provided on the mating slide plate 334. A limiting plate 336 connected to the mating spring 335 is provided on the reciprocating rod 332. One end of the reciprocating rod 332 is provided with a supporting top block 333 that slidably cooperates with the blanking lever 233. The supporting top block 333 is of a conical structure.

[0050] Working principle of the placement mechanism 2: When the placement mechanism 2 operates, first, the position of the placement plate 22 on the placement rack 21 can be adjusted by the adjusting nut 221 to meet the placement requirements of traditional Chinese medicinal materials of different sizes.

[0051] With the movement of the reciprocating rack 331, the reciprocating rack 331 drives the mating spring 335, the limiting plate 336, the mating slide plate 334 and the supporting top block 333 to move synchronously through the reciprocating rod 332. When the supporting top block 333 moves towards the blanking lever 233, the conical supporting top block 333 drives the positioning rotating plate 23 to rotate through the blanking lever 233, and the blanking lower plate 232 and the blanking upper plate 231 move up synchronously. At this time, a traditional Chinese medicinal material moves along the placement rack 21 under the action of gravity to contact the material blocking rotating plate 24, thereby realizing the single movement of the traditional Chinese medicinal material. At the same time, the mating slide plate 334 drives the material blocking rack 242 to slide, and the material blocking rack 242 drives the material blocking rotating plate 24 to rotate through the material blocking gear 241, facilitating the clamping mechanism 4 to clamp and move the traditional Chinese medicinal material.

[0052] The position of the placement plate 22 on the placement rack 21 can be conveniently adjusted by the adjusting nut 221 to easily meet the placement requirements of various traditional Chinese medicinal materials of different sizes, greatly improving the versatility of the equipment. The coordinated operation of the reciprocating rack 331, the reciprocating rod 332, the supporting top block 333 and the positioning rotating plate 23, the blanking upper plate 231 and the blanking lower plate 232 realizes the single and orderly movement of traditional Chinese medicinal materials, effectively avoiding the phenomenon of multi-materials or mis-materials, providing a solid guarantee for subsequent precise transplanting. The close linkage is formed between the mating spring 335, the limiting plate 336, the mating slide plate 334 and the material blocking rack 242 and the material blocking rotating plate 24. While realizing the single movement of traditional Chinese medicinal materials, the material blocking rotating plate 24 is timely opened, enabling the clamping mechanism 4 to smoothly clamp. The whole process is smooth and efficient, significantly improving the coherence and automation level of the equipment operation.

[0053] In the specific implementation of the present invention, first, conduct a detailed inspection of the entire device. Check the frame 1 to ensure no deformation or damage, and that the connections of each mechanism are stable. Examine the connection part between the guide plate 11 and the pick-and-place plate 321 to ensure smooth sliding. Confirm that the clamping mechanism 4 is firmly installed on the pick-and-place plate 321. Check the connections between the components of the soil spreading mechanism 5 to prevent loosening. Examine the appearances of the pick-and-place motor 34, the first electric push rod 322, the second electric push rod 512, and the soil spreading motor 513 to ensure no damage, and that the power cord connections are tight without safety hazards such as short circuits or open circuits.

[0054] After that, according to Chinese medicinal materials of different sizes such as Salvia miltiorrhiza, Rehmannia glutinosa, Polygonum multiflorum, and Astragalus membranaceus, precisely adjust the height of the placement plate 22 on the placement rack 21 by rotating the adjusting nut 221 to provide a suitable placement position for the Chinese medicinal materials. Neatly place the Chinese medicinal materials such as Salvia miltiorrhiza, Rehmannia glutinosa, Polygonum multiflorum, and Astragalus membranaceus to be transplanted on the placement plate 22, ensuring orderly arrangement and avoiding mutual extrusion or obstruction of subsequent feeding actions.

[0055] Then, the placement mechanism 2 conveys the roots of Chinese medicinal materials such as Salvia miltiorrhiza, Rehmannia glutinosa, Polygonum multiflorum, and Astragalus membranaceus to the pick-and-place station in sequence. At the same time, the soil spreading mechanism 5 digs standardized soil pits in the land. The power mechanism drives the pick-and-place rotating column 31 to rotate reciprocally, and the pick-and-place plate 321 moves along the guide groove 111. When the pick-and-place plate 321 moves along the a section of the guide groove, the pick-and-place plate 321 moves in the up and down direction, thereby realizing the placement of the roots of Chinese medicinal materials. When the pick-and-place plate 321 moves along the b section of the guide groove, the pick-and-place plate 321 turns. When the pick-and-place plate 321 moves along the c section of the guide groove, the pick-and-place plate 321 grabs the roots of Chinese medicinal materials. The clamping mechanism 4 grabs the roots of Chinese medicinal materials and, through the smooth turning of the rounded rectangle trajectory, gently embeds the roots into the soil pits in a horizontal posture to complete single-plant transplantation. After that, the soil spreading mechanism 5 synchronously performs soil covering and compaction operations. In this way, it circulates repeatedly to realize the lossless batch transplantation of the roots of Chinese medicinal materials such as Salvia miltiorrhiza, Rehmannia glutinosa, Polygonum multiflorum, and Astragalus membranaceus, forming an integrated flow operation mode of pit digging, transplantation, and soil covering, greatly improving the transplantation efficiency, reducing the damage rate of the roots of Chinese medicinal materials, and enhancing the stability and survival rate of transplantation.

[0056] The above describes the present invention and its implementation manners.

Generally speaking, if those of ordinary skill in the art are inspired by it and, without departing from the purpose of the present invention, creatively design a structural manner and an embodiment similar to this technical solution without creative efforts, they shall fall within the protection scope of the present invention.
