Description

Technical Field

[0001] This invention belongs to the field of automated machinery technology, specifically relating to a harvesting device and method for Prunella vulgaris. Background Technology

[0002] Prunella vulgaris is a perennial herbaceous plant belonging to the Lamiaceae family. It grows only 15 to 30 centimeters tall, with highly branched stems that creep along the ground. Its fruit spikes are terminal and fragile. Currently, harvesting Prunella vulgaris is primarily done manually, which is labor-intensive, inefficient, and cannot meet the needs of large-scale cultivation. Existing small crop harvesters are mostly designed for grains such as wheat and rice, and their headers are structurally limited, with the lowest stubble often exceeding 10 centimeters, making it easy to miss low-lying fruit spikes. Forcibly lowering the header risks damage to the blades and soil, making them unsuitable for harvesting Prunella vulgaris. Furthermore, mature Prunella vulgaris fruit spikes are brittle and easily fall off. The forces generated by existing harvesters during brushing, pulling, or vibration far exceed the fruit spike bonding strength threshold, resulting in significant grain loss in the field. In addition, the intertwined stems and branches of Prunella vulgaris easily entangle cutters, conveyor chains, or harvesting rollers, causing frequent blockages and shutdowns, severely impacting operational efficiency. Summary of the Invention

[0003] The purpose of this invention is to provide a harvesting device and method for Prunella vulgaris, so as to at least solve one of the above-mentioned technical problems.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A device for harvesting selfheal (Prunella vulgaris) includes: The reeling part rotates around its own axis and is provided with a first reeling tooth; A cutting section is provided below the reeling section; A first conveying section, which rotates around its own axis, is provided with a second tooth, and is located behind the cutting section; The second conveying section rotates counterclockwise from bottom to top. The second conveying section is provided with a third tooth and is located behind the first conveying section. The transmission unit is connected to the reeling unit, the cutting unit, the first conveying unit, and the second conveying unit in a transmission manner. During operation, the first tooth guides and straightens the Prunella vulgaris so that it neatly enters the cutting section and is cut. The second tooth adjusts the posture of the cut Prunella vulgaris and neatly feeds it into the second conveying section. The third tooth receives the neatly cut Prunella vulgaris and completes the conveying of the Prunella vulgaris.

[0005] In some embodiments, the transmission unit includes a drive motor, a first sprocket and chain assembly, a second sprocket and chain assembly, a third sprocket and chain assembly, a fourth sprocket and chain assembly, and a fifth sprocket and chain assembly. The output end of the drive motor is connected to the input end of the second conveying unit via the first sprocket and chain assembly. The second conveying unit is driven by the second sprocket and chain assembly. The output end of the second conveying unit is connected to the input end of the first conveying unit via the third sprocket and chain assembly. The output end of the first conveying unit is connected to the input end of the cutting unit and the input end of the reeling unit via the fifth sprocket and chain assembly and the fourth sprocket and chain assembly, respectively.

[0006] In some embodiments, the reeling part includes a reel shaft, a reel, a connecting rod, and the first reel teeth. The reel shaft is connected to the fourth sprocket and chain assembly. The reel is respectively fitted at both ends of the reel shaft. A plurality of connecting rods are evenly distributed circumferentially between the two reel wheels. A plurality of the first reel teeth are evenly spaced on the plurality of connecting rods. The reel rotates around the reel shaft to drive the first reel teeth to rotate.

[0007] In some embodiments, the first tooth includes a straight segment and a curved segment, the straight segment and the curved segment being integrally formed, the straight segment extending radially outward along the reel, and the curved segment located at the end of the straight segment away from the reel and curving in the opposite direction of rotation of the reel.

[0008] In some embodiments, the cutting section includes a moving blade, a sine mechanism, a fixed blade, and a bevel gear pair. The moving blade and the fixed blade are stacked one on top of each other. One end of the moving blade is connected to the sine mechanism. The sine mechanism is connected to the fifth sprocket and chain group through the bevel gear pair. The moving blade reciprocates linearly relative to the fixed blade.

[0009] In some embodiments, the first conveying part includes a roller shaft, a roller, and the second teeth. The roller shaft is connected to the third sprocket chain assembly. The roller is sleeved on the roller shaft. The roller has multiple rows of the second teeth evenly distributed around its circumference. The roller rotates around the roller shaft to drive the second teeth to rotate. The second teeth are bent in the opposite direction to the rotation direction of the roller.

[0010] In some embodiments, the second conveying unit includes a conveyor belt drive shaft, a conveyor belt driven shaft, a conveyor belt, connecting strips, and the third teeth. The conveyor belt driven shaft and the conveyor belt drive shaft are arranged vertically opposite each other. The conveyor belt drive shaft is connected to the first sprocket and chain assembly. The conveyor belt driven shaft and the conveyor belt drive shaft are connected by a transmission through the second sprocket and chain assembly. The conveyor belt is wound around both ends of the conveyor belt driven shaft and the conveyor belt drive shaft. A plurality of connecting strips are provided at equal intervals between the two conveyor belts. A plurality of third teeth are provided at equal intervals on the plurality of connecting strips. The conveyor belt rotates counterclockwise from bottom to top to drive the third teeth to move from bottom to top.

[0011] In some embodiments, a collection section is further included, which is located behind the second conveying section and receives the selfheal grass conveyed by the second conveying section.

[0012] In some embodiments, the device further includes a frame, which includes a first frame, a second frame, and a protective box. The first frame is provided with the second conveying section, the second frame is located below the first frame, and the second frame is provided with the reeling section, the cutting section, and the first conveying section. The protective box is located on one side of the first frame, and the transmission section is provided on the same side of the first and second frames. The collecting section is located at the rear of the first frame.

[0013] A method for harvesting Prunella vulgaris, using the aforementioned Prunella vulgaris harvesting equipment, includes the following steps: Start the drive motor, which drives the second conveyor unit to move through the first sprocket and chain group and the second sprocket and chain group. The output end of the second conveyor unit drives the first conveyor unit to move through the third sprocket and chain group. The output end of the first conveyor unit drives the reeling part to move through the fourth sprocket and chain group and drives the cutting part to move through the fifth sprocket and chain group. The plucking part rotates around its own axis so that the first plucking tooth on the plucking part inserts into the Prunella vulgaris plant clump. As the Prunella vulgaris harvesting equipment moves forward, the first plucking tooth straightens the messy Prunella vulgaris plants so that neat Prunella vulgaris can be fed into the cutting part. The moving blade on the cutting section reciprocates linearly relative to the fixed blade to cut the Prunella vulgaris; The cut Prunella vulgaris falls into the first conveying section one by one. The first conveying section rotates around its own axis so that the second pick on the first conveying section gradually adjusts the posture of the messy Prunella vulgaris after cutting and conveys the neat Prunella vulgaris to the rear. The neatly arranged selfheal grass falls one by one into the third tooth of the second conveying section. The second conveying section rotates counterclockwise from bottom to top so that the third tooth gradually conveys the selfheal grass to the collection section at the rear.

[0014] Compared with the prior art, the technical solution provided in this application has at least the following beneficial effects: This invention achieves mechanization of the harvesting process of Prunella vulgaris by rationally setting up the plucking section, cutting section, first conveying section, second conveying section and transmission section. It can reduce the intensity of manual labor and improve harvesting efficiency. It is especially suitable for mechanized harvesting in small-area Prunella vulgaris planting areas. Moreover, the equipment has a simple and compact structure and is easy and flexible to operate.

[0015] This invention first guides and straightens the messy *Prunella vulgaris* plants through a pruning section, feeding the neat *Prunella vulgaris* into a cutting section. The cutting section then severs the *Prunella vulgaris*, and the resulting messy stalks and ears fall sequentially into a first conveying section. The first conveying section gradually adjusts the posture of the *Prunella vulgaris*, ensuring they are neat and facing roughly the same direction, before conveying the neat *Prunella vulgaris* to the rear of the first conveying section. Finally, the neat *Prunella vulgaris* (stems and ears) fall sequentially into a second conveying section, from which they are transported to a collection section. This integrated operation of straightening, cutting, conveying, and collecting *Prunella vulgaris* reduces missed ear cutting and grain loss, lowers equipment failure rates, and offers advantages of low loss, high efficiency, and high throughput.

[0016] This invention employs a power distribution method driven by a single motor and driven by a multi-stage sprocket and chain. The sprocket transmission mechanism enables the synchronous operation of the plucking section, the cutting section, the first conveying section, and the second conveying section. By reducing the number of power equipment and improving transmission stability, this invention achieves continuous plucking, cutting, conveying, and collection of Prunella vulgaris, effectively improving harvesting efficiency.

[0024] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments.

[0025] Please see Figures 1 to 7This invention provides a Prunella vulgaris harvesting device, which includes a frame 10, a lifting section 20, a cutting section 30, a first conveying section 40, a second conveying section 50, a transmission section 60, and a collecting section 70. The frame 10 serves as the main support for the entire device, used to install and connect the various working components. The lifting section 20 is located at the front end of the frame 10, used to straighten and guide lodged or disordered Prunella vulgaris plants neatly into the working area of ​​the cutting section 30. The cutting section 30 is located below the lifting section 20, used to cut the Prunella vulgaris, leaving only the stems and fruit spikes. The first conveying section 40 is located behind the cutting section 30, used to adjust the posture of the disordered, cut Prunella vulgaris plants gradually falling into the working area of ​​the first conveying section 40, making them neat and oriented towards the base. The neatly cut Prunella vulgaris is transported to the rear of the first conveying section 40; the second conveying section 50 is located behind the first conveying section 40 and is used to receive the neatly cut Prunella vulgaris and transport it to the collection section 70 behind it; the collection section 70 is located behind the second conveying section 50 and is used to collect the neatly cut Prunella vulgaris (i.e., stems and ears of fruit) transported by the second conveying section 50; the transmission section 60 is located on one side of the frame 10 and is used to synchronously drive the reeling section 20, the cutting section 30, the first conveying section 40 and the second conveying section 50 to make the equipment operate in a coordinated manner.

[0026] Specifically, the aforementioned frame 10 includes a first frame 11, a second frame 12, and a protective box 13. The first frame 11 is vertically arranged, and a second conveying unit 50 is installed inside it. The second frame 12 is located below the first frame 11 and is horizontally arranged. A reeling unit 20, a cutting unit 30, and a first conveying unit 40 are installed sequentially from front to back on the second frame 12. The protective box 13 is installed on one side of the first frame 11 to protect part of the transmission unit 60, preventing soil, weeds, and other debris from entering the transmission unit 60 during field operations, thus improving the stability of equipment operation. The transmission unit 60 is installed on the same side of the first frame 11 and the second frame 12 to facilitate the transmission connection between the transmission unit 60 and the reeling unit 20, the cutting unit 30, the first conveying unit 40, and the second conveying unit 50. A collecting unit 70 is installed at the rear of the first frame 11 to ensure continuous and stable operation of the equipment.

[0027] The aforementioned reeling section 20 includes a reel shaft 21, a reel 22, connecting rods 23, and first reeling teeth 24. The two ends of the reel shaft 21 are rotatably mounted on the front end of the second frame 12. A fourth sprocket and chain assembly is connected to one end of the reel shaft 21 on the outer side of the second frame 12. Reels 22 are respectively fitted onto both ends of the reel shaft 21 on the inner side of the second frame 12. Three connecting rods 23 are evenly distributed circumferentially along the edge between the two reels 22. Multiple first reeling teeth 24 are evenly spaced along the axial direction of the three connecting rods 23. Each first reeling tooth 24 includes a straight segment and a curved segment, with the straight segment and curved segment integrally formed. The straight segment extends radially outward along the reel 22, and the curved segment is located at the end of the straight segment away from the reel 22 and curves in the opposite direction of the reel 22's rotation. When the fourth sprocket chain group is running, the reel 22 can be driven to rotate at a low speed around the reel shaft 21 via the reel shaft 21. This, in turn, can drive the first tooth 24 on the connecting rod 23 to rotate at a low speed around the reel shaft 21. This allows the first tooth 24 to insert into the lodged or messy Prunella vulgaris plants in the field. As the Prunella vulgaris harvesting equipment moves forward, the first tooth 24 can straighten and guide the lodged or messy Prunella vulgaris plants, so that the Prunella vulgaris plants can gather towards the center of the equipment and the working area of ​​the cutting section 30, and the Prunella vulgaris can be neatly fed into the working area of ​​the cutting section 30, improving the continuity and integrity of the harvesting process and reducing missed cuts and blockages.

[0028] The aforementioned cutting section 30 includes a moving blade 31, a sine mechanism 32, a fixed blade 33, and a bevel gear assembly. The fixed blade 33 is fixedly mounted at the front end of the second frame 12 in a low, near-ground position. The moving blade 31 and the fixed blade 33 are stacked vertically, with a pre-set safety clearance between the moving blade 31 and the outermost edge of the first gear 24. A sine mechanism 32 is mounted on one end of the moving blade 31, on the outer side of the second frame 12. The sine mechanism 32 is connected to a driven bevel gear 613 in the bevel gear assembly mounted on the shaft via a shaft. The driving bevel gear 612 in the bevel gear assembly is then connected to the fifth sprocket and chain assembly via a connecting shaft. When the fifth sprocket chain group is running, the driven bevel gear 613 can be rotated by the driving bevel gear 612 to change the direction of power transmission. Then, the moving blade 31 can be driven to move back and forth linearly relative to the fixed blade 33 by the sine mechanism 32, so as to neatly cut the neatly guided stems of Prunella vulgaris at a certain height above the ground to harvest the stems and fruit ears.

[0029] The aforementioned first conveying unit 40 includes a roller shaft 41, a roller 42, and second teeth 43. The two ends of the roller shaft 41 are rotatably mounted on the frame 12. The roller 42 is sleeved on the roller shaft inside the frame 12. Three rows of second teeth 43 are evenly distributed circumferentially along the axial direction of the roller 42. Each row of second teeth 43 is evenly spaced and bent in the opposite direction to the rotation of the roller 42. A third sprocket chain group, a fourth sprocket chain group, and a fifth sprocket chain group are connected to one end of the roller shaft 41 and to the outside of the frame 12. When the third sprocket chain group is running, it can drive the roller 42 to rotate at a low speed around the roller shaft 41 via the roller shaft 41. In turn, it can drive the second teeth 43 on the roller 42 to rotate at a low speed around the roller shaft 41. This is to facilitate the spatial orientation adjustment of the messy selfheal after it has been cut by the cutting part 30 and falls into the working area of ​​the first conveying part 40, so that it becomes neat and the orientation is basically the same. In other words, after the selfheal is cut by the cutting part 30, it will become somewhat messy. Under the gradual adjustment of the messy selfheal, i.e. the stems and fruit spikes, by the multiple rows of second teeth 43 on the roller 42, the messy selfheal can become neat again. Moreover, with the help of the rotation of the roller 42, the neat selfheal can be smoothly conveyed from the front of the roller 42 to the rear of the roller 42, preventing entanglement and blockage.

[0030] The second conveying unit 50 mentioned above includes a conveyor belt drive shaft 51, a conveyor belt driven shaft 52, a conveyor belt 53, a third gear 54, and a connecting bar 55. The driven shaft 52 of the conveyor belt is arranged parallel to the drive shaft 51 of the conveyor belt, and both ends of the driven shaft 52 and the drive shaft 51 are rotatably mounted on the frame 11. A conveyor belt 53 is wound around both ends of the driven shaft 52 and the drive shaft 51 on the inner side of the frame 11. Multiple connecting strips 55 are equally spaced between the two conveyor belts 53. Multiple third teeth 54 are connected to the multiple connecting strips 55 at equal intervals along the axial direction of the connecting strips 55. The third teeth 54 have a wide bearing surface and the bearing surface is perpendicular to the axial direction of the connecting strips 55. At the same time, the bearing surface of the third teeth 54 has a certain coefficient of friction. A first sprocket and chain group, a second sprocket and chain group, and a third sprocket and chain group are connected to one end of the drive shaft 51 on the outer side of the frame 11. The driven shaft 52 and the drive shaft 51 of the conveyor belt are connected by the second sprocket and chain group. When the first sprocket and chain assembly is running, it can drive the second sprocket and chain assembly to run through the drive shaft 51 of the conveyor belt, which in turn drives the driven shaft 52 of the conveyor belt to run. This drives the transmission belt 53 and its third teeth 54 to run counterclockwise from bottom to top, so that the neatly arranged Prunella vulgaris (stems and ears of fruit) gradually conveyed / pushed by the first conveyor section 40 can be received through the gap between the third teeth 54 and the two third teeth 54. The Prunella vulgaris is then transported in an orderly manner from the front of the second conveyor section 50 to the rear of the second conveyor section 50, so as to achieve continuous and stable transportation of Prunella vulgaris.

[0031] The aforementioned transmission unit 60 includes a drive motor 61, a reducer 62, a first sprocket and chain assembly, a second sprocket and chain assembly, a third sprocket and chain assembly, a fourth sprocket and chain assembly, and a fifth sprocket and chain assembly. The drive motor 61 is mounted at the rear of the frame 11. The output end of the drive motor 61 is connected to the reducer 62 via a coupling. The output end of the reducer 62 is equipped with a first driving sprocket 63 from the first sprocket and chain assembly, and the input end of the conveyor belt drive shaft 51 is equipped with a first driven sprocket 64 from the first sprocket and chain assembly. A first chain 615 is installed between the first driving sprocket 63 and the first driven sprocket 64. Thus, the drive motor 61, after being reduced in speed and increased in torque by the reducer 62, drives the conveyor belt drive shaft 51 to rotate at a certain speed via the first sprocket and chain assembly. The conveyor belt drive shaft 51... The conveyor belt also includes a second drive sprocket 65 from a second sprocket and chain assembly, and a second driven sprocket 66 from the same assembly mounted on the driven shaft 52. A second chain 616 is installed between the second drive sprocket 65 and the second driven sprocket 66. Thus, the drive shaft 51 can drive the driven shaft 52 to rotate at a certain speed via the second sprocket and chain assembly, which in turn drives the third gear 54 via the transmission belt 53. The drive shaft 51 also includes a third drive sprocket 67 from a third sprocket and chain assembly, and a third driven sprocket from the same assembly mounted on the roller shaft 41. 619, and a third chain 617 is installed between the third driving sprocket 67 and the third driven sprocket 619, so that the drive shaft 51 of the conveyor belt can drive the roller shaft 41 to rotate at a certain speed through the third sprocket and chain assembly, and then drive the second gear 43 to work through the roller 42; the roller shaft 41 is also equipped with the fifth driving sprocket 69 of the fifth sprocket and chain assembly, and the connecting shaft of the drive bevel gear 612 is equipped with the fifth driven sprocket 611 of the fifth sprocket and chain assembly, and a fifth chain 620 is installed between the fifth driving sprocket 69 and the fifth driven sprocket 611, so that the roller shaft 41 can drive the roller shaft 42 to rotate at a certain speed through the third sprocket and chain assembly. The fifth sprocket and chain assembly drives the driving bevel gear 612 to rotate at a certain speed, which in turn drives the moving blade 31 through the driven bevel gear 613 and the sine mechanism 32. The drum shaft 41 is also equipped with the fourth driving sprocket 68 from the fourth sprocket and chain assembly, and the reel shaft 21 is equipped with the fourth driven sprocket 614 from the fourth sprocket and chain assembly. A fourth chain 618 is installed between the fourth driving sprocket 68 and the fourth driven sprocket 614. Thus, the drum shaft 41 drives the reel shaft 21 to rotate at a certain speed through the fourth sprocket and chain assembly, which in turn drives the first reeling tooth 24 through the reel 22. In short, a single drive motor 61 and multiple sprocket and chain assemblies can synchronously drive the reeling section 20, the cutting section 30, the first conveying section 40, and the second conveying section 50 to work in coordination, achieving integrated operation of straightening, cutting, conveying, and collecting the selfheal.

[0032] The aforementioned collection section 70 includes a collection box 71, which is installed behind the frame 11, i.e. behind the second conveying section 50. It is used to receive neatly arranged Prunella vulgaris containing only stems and ears of fruit that are conveyed by the third tooth 54 in the second conveying section 50, so as to realize centralized storage of harvested materials and reduce the amount of labor caused by secondary manual collection.

[0033] This invention, through the rational arrangement of the plucking section, cutting section, first conveying section, second conveying section, transmission section, and collection section, achieves mechanization of the harvesting process of Prunella vulgaris, reducing manual labor intensity and improving harvesting efficiency. It is particularly suitable for mechanized harvesting in small-area Prunella vulgaris planting areas, and the equipment has a simple and compact structure and is easy and flexible to operate. At the same time, it adopts a power distribution method of single motor drive and multi-stage sprocket chain transmission, and realizes the synchronous operation of the plucking section, cutting section, first conveying section, and second conveying section through the sprocket transmission mechanism. On the basis of reducing the number of power equipment and improving transmission stability, it realizes the continuous process of plucking, cutting, conveying, and collecting Prunella vulgaris, effectively improving harvesting efficiency.

[0034] This invention also provides a method for harvesting Prunella vulgaris, based on the aforementioned Prunella vulgaris harvesting equipment, specifically including the following steps: S1. Start the drive motor 61. The drive motor 61 drives the second conveyor 50 to move through the first sprocket and chain group and the second sprocket and chain group. The output end of the second conveyor 50 drives the first conveyor 40 to move through the third sprocket and chain group. The output end of the first conveyor 40 drives the reeling part 20 to move through the fourth sprocket and chain group and drives the cutting part 30 to move through the fifth sprocket and chain group.

[0035] Specifically, after the drive motor 61 is reduced in speed and torque by the reducer 62, it drives the drive shaft 51 of the conveyor belt to rotate via the first drive sprocket 63, the first driven sprocket 64, and the first chain 615. The drive shaft 51 drives the driven shaft 52 of the conveyor belt to rotate via the second drive sprocket 65, the second driven sprocket 66, and the second chain 616, thereby causing the conveyor belt 53, carrying the third gear 54, to circulate counterclockwise from bottom to top. Simultaneously, the drive shaft 51 drives the roller shaft 41 to rotate via the third drive sprocket 67, the third driven sprocket 619, and the third chain 617. On one hand, the drum shaft 41 drives the reel shaft 21 to rotate through the fourth drive sprocket 68, the fourth driven sprocket 614 and the fourth chain 618, causing the reel 22 to rotate slowly around the reel shaft 21 with the first reel tooth 24. On the other hand, the drum shaft 41 drives the drive bevel gear 612 to rotate through the fifth drive sprocket 69, the fifth driven sprocket 611 and the fifth chain 620. After the drive bevel gear 612 drives the driven bevel gear 613 to rotate and change the direction of power, it drives the moving blade 31 to reciprocate linearly along the fixed blade 33 through the sine mechanism 32. This completes the start-up preparation of each working part of the equipment.

[0036] S2. The reeling section 20 rotates around its own axis so that the first reeling tooth 24 on the reeling section 20 inserts into the clump of Prunella vulgaris plants. As the Prunella vulgaris harvesting equipment moves forward, the first reeling tooth 24 straightens the messy Prunella vulgaris plants so that neat Prunella vulgaris can be fed into the cutting section 30.

[0037] Specifically, the entire equipment moves forward at a uniform speed along the planting ridge of Prunella vulgaris. The first tooth 24 of the rake part 20 rotates with the rake wheel 22 and inserts into the fallen or messy Prunella vulgaris plants in the area to be harvested in sequence to straighten and guide the plants and gather them into the working area of ​​the cutting part 30 so that the neat Prunella vulgaris can be fed into the working area of ​​the cutting part 30 to cut the stems of Prunella vulgaris.

[0038] S3. The moving blade 31 on the cutting section 30 moves back and forth linearly relative to the fixed blade 33 to cut the selfheal.

[0039] Specifically, the moving blade 31 of the cutting section 30, through reciprocating motion, cooperates with the fixed blade 33 to cut the stems of Prunella vulgaris, retaining only the stems and fruit spikes. Of course, during the cutting process, the reeling section 20 and the cutting section 30 work continuously to ensure that the equipment's travel speed matches the cutting speed, avoiding accumulation or omissions.

[0040] S4. The cut Prunella vulgaris falls into the first conveying section 40 one by one. The first conveying section 40 rotates around its own axis so that the second tooth 43 on the first conveying section 40 gradually adjusts the posture of the messy Prunella vulgaris after cutting and conveys the neat Prunella vulgaris to the rear.

[0041] Specifically, the cut Prunella vulgaris becomes messy again. The messy Prunella vulgaris enters the working area or entrance area of ​​the first conveying section 40 one by one under the push of the subsequent Prunella vulgaris. The roller 42 drives the multiple rows of second teeth 43 to rotate at low speed, adjusting the spatial posture of the messy Prunella vulgaris so that the Prunella vulgaris is rearranged neatly and faces basically the same direction. Under the push of the subsequent Prunella vulgaris and the rotation of the roller 42, the neat Prunella vulgaris is gradually transported to the second conveying section 50 at the rear.

[0042] S5. The neatly arranged selfheal grass falls one after another into the third tooth 54 on the second conveying section 50. The second conveying section 50 rotates counterclockwise from bottom to top so that the third tooth 54 gradually conveys the selfheal grass to the collection section 70 at the rear.

[0043] Specifically, the third tooth 54 of the second conveyor section 50 rotates at a constant speed from bottom to top along with the conveyor belt 53. Due to the certain coefficient of friction and the gaps between the third teeth 54, the neatly arranged Prunella vulgaris from the first conveyor section 40 can be received and continuously transported along the second conveyor section 50 from the front to the rear. Upon reaching the rear, the Prunella vulgaris detaches from the third tooth 54 under the combined action of inertia and gravity and falls into the collection box 71, completing the centralized storage of the Prunella vulgaris. Of course, once the collection box 71 is full of Prunella vulgaris, the equipment can be moved to a designated unloading position, the collection box 71 emptied, and harvesting operations can continue until the harvesting of Prunella vulgaris in the entire planting area is completed.
