Description

Technical Field

[0001] This application relates to the field of Coptis chinensis harvesting technology, specifically to harvesting devices and equipment for harvesting Coptis chinensis. Background Technology

[0002] Coptis chinensis, a "golden herb" in the treasure trove of traditional Chinese medicine, plays an irreplaceable role in clearing heat and drying dampness, purging fire and detoxifying. Currently, the harvesting of Coptis chinensis is mostly carried out manually or semi-mechanized. The harvesting tools used for manual harvesting and those used for semi-mechanized harvesting both employ only simple blades, without any targeted improvements based on the production conditions of Coptis chinensis and the harvested parts, resulting in low harvesting efficiency. Utility Model Content

[0003] The purpose of this application is to overcome the above-mentioned technical deficiencies, propose a harvesting device and a Coptis chinensis harvesting equipment, and solve the technical problem of low harvesting efficiency of Coptis chinensis in the known technology.

[0004] To achieve the above-mentioned technical objectives, this application adopts the following technical solution:

[0005] In a first aspect, this application provides a harvesting device, including a rotating shaft and multiple sets of digging teeth. The multiple sets of digging teeth are sequentially connected to the rotating shaft along its axial direction. Each set of digging teeth includes multiple digging teeth arranged circumferentially around the rotating shaft. Each digging tooth includes a first tooth segment and a second tooth segment. One end of the first tooth segment is connected to the rotating shaft, and the other end of the first tooth segment extends in a direction opposite to the rotating shaft. One end of the second tooth segment is connected to the first tooth segment, and the second tooth segment is inclined relative to the first tooth segment along the circumferential direction of the rotating shaft. Along the circumferential direction of the rotating shaft, the first tooth segment has a first edge and a second edge arranged opposite to each other, and the second tooth segment has a third edge and a fourth edge arranged opposite to each other. The angle between the first edge and the third edge is an obtuse angle, and the second edge and the fourth edge are connected by a rounded transition.

[0006] In some embodiments, along the radial direction of the rotation axis, the thickness of the mining teeth along the axial direction of the rotation axis gradually decreases in a direction away from the rotation axis.

[0007] In some embodiments, along the inclined direction of the second tooth segment, the thickness of the mining tooth along the axial direction of the rotation axis gradually decreases in the direction close to the first edge and the third edge.

[0008] In some embodiments, the mining tooth has a first surface and a second surface arranged opposite to each other along the axial direction of the rotation axis; the first surface and the second surface are symmetrically arranged about the radial tangent of the rotation axis; and the distance between the first surface and the second surface gradually decreases along the circumferential direction of the rotation axis.

[0009] In some embodiments, the first edge is straight, the third edge is straight, the second edge is arc-shaped, and the fourth edge is arc-shaped.

[0010] In some embodiments, the projections of each group of mining teeth along the axial direction of the rotation axis coincide with each other.

[0011] In some embodiments, the rotating shaft has a first end and a second end spaced apart along its axial direction; in the direction from the first end to the second end, the latter group of mining teeth rotates relative to the former group of mining teeth by a preset angle in the circumferential direction of the rotating shaft.

[0012] In some embodiments, a plurality of the mining tooth groups are movably arranged along the axial direction of the rotation axis, and the spacing between two adjacent mining tooth groups is adjustable.

[0013] In some embodiments, the mining tooth assembly further includes an adjusting ring, which is movably sleeved on the rotating shaft along the axial direction of the rotating shaft, and the plurality of mining teeth are connected around the adjusting ring.

[0014] Secondly, this application also provides a Coptis chinensis harvesting device, including a walking device and the aforementioned harvesting device, wherein the harvesting device is connected to the walking device.

[0015] Compared with known technologies, the harvesting device provided in this application allows multiple sets of digging teeth to simultaneously dig Coptis chinensis along the axial direction of the rotation axis, thereby improving harvesting efficiency. Simultaneously, the multiple digging teeth can extract Coptis chinensis from the soil during rotation and transport it to the screening assembly for subsequent screening. A V-shaped cutting edge is formed between the first and third edges of the first and second tooth segments, creating a wedge-shaped cutting effect through double straight surfaces. This increases the contact area between the digging teeth and the Coptis chinensis roots, reducing the pressure per unit area on the roots and thus lowering the likelihood of root breakage during harvesting, thereby increasing the success rate. Furthermore, the arc transition between the second and fourth edges creates a continuous streamlined structure, reducing the possibility of the digging teeth being too sharp relative to the soil and damaging the rhizomes, further improving harvesting quality. In addition, the arc structure between the second and fourth edges can reduce the possibility of soil adhering to the harvesting teeth and reduce the friction between the soil and the harvesting teeth, thereby reducing the movement resistance of the harvesting teeth, improving the energy utilization rate of the harvesting device and improving the harvesting efficiency.

[0028] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art. The terminology used herein in the specification of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The term "or / and" as used herein includes any and all combinations of one or more of the associated listed items.

[0031] Some embodiments of this application are described in detail. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0032] In known technologies, Coptis chinensis is mainly harvested manually or semi-mechanized. Manual harvesting relies on individual vine removal, soil shaking, and leaf cutting, which is labor-intensive and extremely inefficient. During large-scale cultivation, labor costs rise sharply, and the harvest is easily affected by fluctuations in planting time and manpower availability, potentially missing the optimal harvest period and reducing the quality and yield of the harvested Coptis chinensis. Semi-mechanized harvesting tends to focus on a single harvesting step, but still requires manual assistance and involves multiple steps. The simplification of procedures is limited, and the reduction in manpower is limited, resulting in limited overall improvement in harvesting efficiency.

[0033] To address some known technical problems related to the low harvesting efficiency of Coptis chinensis, this application provides a harvesting device that can improve the harvesting efficiency of Coptis chinensis.

[0034] It should be noted that the harvesting device described in this application is used for, but not limited to, the harvesting of Coptis chinensis. For ease of explanation, this application will only use the application of the harvesting device to Coptis chinensis as an example. The principle of the harvesting device in the harvesting of other types of economic crops is essentially the same as that in the harvesting of Coptis chinensis, and will not be described in detail here.

[0035] Please see Figure 1 , Figure 1 This is a schematic diagram of the harvesting device 10 in one embodiment of this application. The harvesting device 10 includes a rotating shaft 11 and multiple sets of digging teeth 12. The axial direction of the rotating shaft 11 is parallel to a first direction X. The multiple sets of digging teeth 12 are sequentially connected to the rotating shaft 11 along its axial direction. (See also: [reference needed]) Figure 2 The mining tooth assembly 12 includes multiple mining teeth 121, which are arranged around the rotating shaft 11 in the circumferential direction W. The mining tooth 121 includes a first tooth segment 1211 and a second tooth segment 1212. One end of the first tooth segment 1211 is connected to the rotating shaft 11, and the other end of the first tooth segment 1211 extends in a direction away from the rotating shaft 11. One end of the second tooth segment 1212 is connected to the first tooth segment 1211, and the second tooth segment 1212 is inclined relative to the first tooth segment 1211 along the circumferential direction W of the rotating shaft 11. Along the circumferential direction W of the rotating shaft 11, the first tooth segment 1211 has a first edge 12111 and a second edge 12112 that are opposite to each other, and the second tooth segment 1212 has a third edge 12121 and a fourth edge 12122 that are opposite to each other. The included angle between the first edge 12111 and the third edge 12121 is an obtuse angle, and the second edge 12112 and the fourth edge 12122 are connected by a circular arc transition.

[0036] In this way, multiple digging teeth 12 can simultaneously dig Coptis chinensis along the axial direction of the rotation axis 11, thereby improving the digging efficiency. Simultaneously, multiple digging teeth 121 can extract Coptis chinensis from the soil during rotation and transport it to the screening component 20 for subsequent screening. A V-shaped cutting edge is formed between the first edge 12111 and the third edge 12121 of the first tooth segment 1211 and the second tooth segment 1212. This creates a wedge-shaped cutting effect through double straight surfaces, increasing the contact area between the digging teeth 121 and the Coptis chinensis root system, reducing the pressure per unit area on the root system, thus reducing the possibility of root breakage during digging and improving the digging success rate. Furthermore, the second edge 12112 and the fourth edge 12122 are connected by a rounded transition, forming a continuous streamlined structure. This reduces the possibility of the digging teeth 121 being too sharp relative to the soil and damaging the rhizome, further improving the harvesting quality. Furthermore, the arc structure between the second edge 12112 and the fourth edge 12122 can reduce the possibility of soil adhering to the harvesting teeth and reduce the friction between the soil and the harvesting teeth, thereby reducing the movement resistance of the harvesting teeth, improving the energy utilization rate of the harvesting device 10 and improving the harvesting efficiency.

[0037] Specifically, the harvesting device 10 also includes a drive component (not shown in the figure). The drive component is connected to the rotating shaft 11 to drive the rotating shaft 11 to rotate. The drive component can be constructed as a motor or other drive mechanism.

[0038] In one embodiment, the first edge 12111 is straight, the third edge 12121 is straight, the second edge 12112 is arc-shaped, and the fourth edge 12122 is arc-shaped.

[0039] In one embodiment, the extension of the tangent of the fourth edge 12122 at the junction of the fourth edge 12122 and the rotation shaft 11 passes through the center of the cross section of the rotation shaft 11.

[0040] In one embodiment, along the radial direction R of the rotation axis 11, the thickness of the mining tooth 121 along the axial direction of the rotation axis 11 gradually decreases in the direction away from the rotation axis 11.

[0041] This design results in a thicker connection between the digging tooth 121 and the rotating shaft 11, while the end of the digging tooth 121 facing away from the connecting shaft is thinner, roughly forming a blade-like structure that is thinner at the front and thicker at the back. This reduces resistance as the thin blade at the tip of the digging tooth 121 cuts into the soil, facilitating rapid penetration of the topsoil and increasing the success rate of harvesting Coptis chinensis. The thicker base of the digging tooth 121 ensures its rigidity, reducing the possibility of deformation and extending its overall lifespan.

[0042] In one embodiment, see Figure 3 Along the inclined direction of the second tooth segment 1212, the thickness of the digging tooth 121 along the axial direction of the rotation shaft 11 gradually decreases in the direction close to the first edge 12111 and the third edge 12121. In this way, the thickness of the digging tooth 121 gradually decreases on the side facing the soil, which can further improve the overall sharpness of the digging tooth 121 while ensuring strength.

[0043] Specifically, the mining tooth 121 has a first surface 1213 and a second surface 1214 arranged opposite to each other along the axial direction of the rotation shaft 11. The first surface 1213 and the second surface 1214 are symmetrically arranged about the radial R tangent of the rotation shaft 11. The distance between the first surface 1213 and the second surface 1214 gradually decreases along the circumferential direction W of the rotation shaft 11.

[0044] In one embodiment, see Figure 1 The rotating shaft 11 has a first end 111 and a second end 112 spaced apart along its axial direction. In the direction from the first end 111 to the second end 112, the latter set of mining teeth 12 rotates relative to the former set of mining teeth 12 in the positive direction of the circumferential W of the rotating shaft 11 by a preset angle.

[0045] In this way, multiple sets of digging teeth 12 are staggered and arranged sequentially, and the multiple digging teeth 121 are roughly spirally staggered along the axial direction of the rotating shaft 11. They can form a spatial spiral array along the axial direction of the rotating shaft 11. During the rotation of the rotating shaft 11, each set of digging teeth 12 digs Coptis chinensis in an alternating manner, which can reduce the empty space in the circumferential W of the connecting shaft. This allows the multiple digging teeth 121 to cover the rotating harvesting area more evenly, thereby improving the harvesting efficiency of Coptis chinensis. In addition, the above design can further avoid multiple digging teeth 121 cutting into the soil simultaneously, which can reduce the soil loosening rate and reduce the loosening or lodging of Coptis chinensis roots and stems caused by concentrated cutting into the soil, thereby improving harvesting stability.

[0046] Specifically, the preset angle can be between 5° and 30°. For example, the preset angle can be 5°, 10°, 15°, 20°, 25°, 30°, etc. The specific preset angle can be adjusted according to actual needs.

[0047] In one embodiment, see Figure 4 The projections of each group of mining teeth 12 along the axial direction of the rotating shaft 11 coincide with each other.

[0048] In one embodiment, multiple sets of mining teeth 12 are fixedly connected to the rotating shaft 11 to improve the overall rigidity of the harvesting device 10.

[0049] In one embodiment, see Figure 2Multiple mining tooth groups 12 are movably arranged along the axial direction of the rotating shaft 11, and the spacing between two adjacent mining tooth groups 12 can be adjusted.

[0050] Thus, when facing the harvesting of Coptis chinensis with different planting densities, the spacing between the digging teeth 12 can be adjusted so that the digging range of multiple digging teeth 12 is roughly similar to and matched with the planting density of Coptis chinensis, thereby reducing the harvesting omission rate and increasing the harvest volume.

[0051] In one embodiment, see Figure 2 The mining tooth assembly 12 also includes an adjusting ring 122. The adjusting ring 122 is movably sleeved on the rotating shaft 11 along the axial direction of the rotating shaft 11, and multiple mining teeth 121 are connected to the adjusting ring 122 around it.

[0052] Thus, by adjusting the spacing between two adjacent adjusting rings 122 along the axial direction of the rotating shaft 11, the distribution of the digging teeth 12 can be made roughly similar to the distribution of the Coptis chinensis plants. The adjusting rings 122 and the rotating shaft 11 can be connected by threads or detachably by fasteners to ensure the reliability of the movement of the multiple digging teeth 12 driven by the rotating shaft 11.

[0053] See Figures 5 to 10 This embodiment also provides a Coptis chinensis harvesting device 1, including the harvesting device 10 of any of the aforementioned embodiments. The Coptis chinensis harvesting device 1 further includes a screening component 20, a collecting device 30, and a lifting device 40. The harvesting device 10 is connected to one end of the screening component 20 and is used to harvest Coptis chinensis to the screening component 20. The screening component 20 has multiple screening holes 231. The screening component 20 is used to receive Coptis chinensis and allow impurities attached to the Coptis chinensis to be discharged through the screening holes 231. The collecting device 30 is located at the end of the screening component 20 away from the harvesting device 10 and is used to collect the Coptis chinensis after screening by the screening component 20. The lifting device 40 connects the collecting device 30 and the screening component 20, and is used to move the screening component 20 between near the ground and near the collecting device 30.

[0054] According to the Coptis chinensis harvesting device 1 of this embodiment, during the harvesting process, the lifting device 40 moves the screening component 20 closer to the ground, and the harvesting device 10 digs the Coptis chinensis from the ground to the screening component 20. The screening component 20 receives and screens the Coptis chinensis, so that soil and other impurities from the roots of the Coptis chinensis are discharged through the screening holes 231. After the screening component 20 completes screening, the lifting device 40 moves the screening component 20 closer to the collecting device 30, so that the Coptis chinensis is transported from the screening component 20 to the collecting device 30, thereby completing the collection of the screened Coptis chinensis. After the Coptis chinensis on the screening component 20 is collected, the lifting device 40 moves the screening component 20 closer to the ground again to perform the next Coptis chinensis harvest. Therefore, the Coptis chinensis harvesting device of this application can simultaneously realize the functions of harvesting, shaking off soil and conveying Coptis chinensis by the screening component 20 and the harvesting device 10 through the lifting device 40. This allows the harvesting process of Coptis chinensis, such as harvesting, shaking off soil and collecting, to be completed automatically. Compared with the known technology that first pulls up the roots of Coptis chinensis and then performs a secondary process of soil removal, the harvesting efficiency of Coptis chinensis can be greatly improved.

[0055] For ease of description, this embodiment defines a first direction X, a second direction Y, and a third direction Z. The first direction X is parallel to the length direction of the harvesting device 10. The second direction Y is perpendicular to the first direction X, and the harvesting device 10, the screening component 20, and the collecting device 30 are distributed along the second direction Y. The third direction Z is the direction of gravity. The third direction Z is perpendicular to both the first direction X and the second direction Y. In other embodiments, the first direction X, the second direction Y, and the third direction Z can also be arranged obliquely to each other.

[0056] See Figure 5 and Figure 6 In this embodiment, the Coptis chinensis harvesting equipment 1 also includes a walking device 50. The walking device 50 is located on the side of the screening component 20 away from the harvesting device 10. The walking device 50 includes a support plate 51 and walking wheels 52. The walking wheels 52 are located on the bottom side of the support plate 51, the collecting device 30 is located on the support plate 51, and the lifting device 40 is rotatably connected to the support plate 51. The walking device 50 enables automatic walking and harvesting of Coptis chinensis in the planting area, improving harvesting efficiency. There are two sets of walking wheels 52, which are respectively constructed as front wheels and rear wheels.

[0057] In this embodiment, see Figure 7The screening assembly 20 includes a mounting frame 21, a vibrating element 22, and a screening plate 23. The mounting frame 21 is connected to the lifting device 40, and one end of the mounting frame 21 facing away from the collecting device 30 is connected to the harvesting device 10. The screening plate 23 is located between the harvesting device 10 and the collecting device 30, and the screening plate 23 has multiple screening holes 231. One end of the vibrating element 22 is connected to the mounting frame 21, and the other end of the vibrating element 22 is connected to the screening plate 23, and is used to drive the screening plate 23 to vibrate, so as to drive the Coptis chinensis carried on the screening plate 23 to vibrate, and cause the impurities attached to the Coptis chinensis to fall from the screening holes 231. In this way, the Coptis chinensis collected by the harvesting device 10 can fall directly onto the screening plate 23. Afterwards, the vibrating element 22 drives the screening plate 23 to vibrate relative to the mounting frame 21, which can drive the Coptis chinensis falling onto the screening plate 23 to vibrate, thereby cleaning the Coptis chinensis. This eliminates the need for conveying the Coptis chinensis harvested by the harvesting device 10 to the screening plate 23, further improving the overall harvesting efficiency of Coptis chinensis.

[0058] Among them, debris can be soil or gravel attached to the roots of Coptis chinensis.

[0059] Specifically, the maximum diameter of the sieve hole 231 is smaller than the outer diameter of the rhizome of Coptis chinensis, thus ensuring that Coptis chinensis will not be discharged from the sieve hole 231 during the vibration of the sieve plate 23.

[0060] Optionally, the screening holes 231 can be constructed as round holes, oblong holes, or irregularly shaped holes. Multiple screening holes 231 can be distributed in a horizontal and vertical array, or in other distribution methods.

[0061] In this embodiment, see Figure 7 There are two mounting frames 21, which are spaced apart along the extension direction of the harvesting device 10. The two mounting frames 21 are connected to both ends of the harvesting device 10. There are multiple vibrating elements 22, and each mounting frame 21 is connected to both sides of the screening plate 23 via multiple vibrating elements 22. This improves the overall stability of the screening plate 23, and the mounting frames 21 also act as a barrier for the Coptis chinensis, keeping it on the screening plate 23 and reducing the possibility of it falling off the sides of the screening plate 23 during vibration, thereby increasing the harvested quantity of Coptis chinensis.

[0062] Specifically, the vibrating component 22 can be a vibrating motor. During the operation of the vibrating motor, the screening plate 23 is driven to generate high-frequency vibration, which in turn drives the Coptis chinensis carried by the screening plate 23 to vibrate.

[0063] Optionally, each mounting frame 21 is connected to one side of the screening plate 23 by a plurality of vibrating elements 22 spaced apart along the length of the mounting frame 21.

[0064] In this embodiment, see Figure 8The lifting device 40 includes a first lifting arm 41 and a second lifting arm 42. One end of the first lifting arm 41 is rotatably connected to the collecting device 30, and the first lifting arm 41 extends downward along the direction of gravity. One end of the second lifting arm 42 is rotatably connected to the other end of the first lifting arm 41, and the second lifting arm 42 extends toward the harvesting device 10. The other end of the second lifting arm 42 is connected to the screening assembly 20. Thus, rotation of the first lifting arm 41 drives rotation of the second lifting arm 42, which in turn drives the screening assembly 20 to move closer to the ground or closer to the collecting device 30 along the third direction Z, thereby conveying the harvested Coptis chinensis to the collecting device 30. The first lifting arm 41 can be driven by a motor or other drive components.

[0065] Specifically, see Figure 6 The first lifting arm 41 is rotatably connected to the support plate 51 via the first pivot 53.

[0066] In one embodiment, see Figure 8 The lifting device 40 also includes a buffer section 43. The buffer section 43 is located between the second lifting arm 42 and the mounting frame 21 of the screening assembly 20. In this way, the buffer section 43 can reduce the vibration transmitted from the screening plate 23 to the lifting device 40, so as to ensure the structural stability of the lifting device 40.

[0067] Specifically, the buffer part 43 can be set as an elastic column or a buffer rubber, etc.

[0068] In this embodiment, see Figure 6 The collecting device 30 includes a transmission component 31 and a storage component 32. One end of the transmission component 31 is positioned opposite the end of the screening component 20 that is away from the collecting device 10, and the storage component 32 is located at the end of the transmission component 31 that is away from the screening component 20. The transmission component 31 is used to receive and transmit the Coptis chinensis after screening by the screening component 20, and to transport the Coptis chinensis to the storage component 32, which is used to store the Coptis chinensis.

[0069] In this embodiment, see Figure 9 The conveying component 31 includes a conveyor belt 311 and multiple partitions 312. The conveyor belt 311 is located between the inlet 325 of the screening component 20 and the storage component 32. The multiple partitions 312 are spaced apart on the conveyor belt 311 along the spacing direction between the screening component 20 and the storage component 32. A partition groove 313 is formed between two adjacent partitions 312 and the conveyor belt 311. The partition groove 313 is used to contain Coptis chinensis. In this way, after the harvesting device 10 and the screening component 20 are activated, Coptis chinensis can be sequentially conveyed into each partition groove 313, thereby avoiding the accumulation of Coptis chinensis on the conveyor belt 311, reducing damage to Coptis chinensis during the conveying process, and improving the harvesting quality of Coptis chinensis.

[0070] Specifically, the distance between two adjacent partitions 312 along the direction of movement of the conveyor belt 311 is approximately the same as the length of the rhizome of Coptis chinensis.

[0071] In one embodiment, the partition 312 includes a base plate 3121 and a partition plate 3122. The base plate 3121 is fixedly connected to the conveyor belt 311. The partition plate 3122 extends in a direction away from the conveyor belt 311. A partition groove 313 is formed between the two partition plates 3122 of two adjacent partitions 312 and the conveyor belt 311.

[0072] In one embodiment, the surface of the conveyor belt 311 is also provided with a flexible anti-slip pad (not shown in the figure). The flexible anti-slip pad can reduce the possibility of Coptis chinensis slipping during the conveying process, thereby ensuring that Coptis chinensis is conveyed into the storage component 32 and improving the overall harvesting efficiency of Coptis chinensis.

[0073] In one embodiment, see Figure 9 See also Figure 6 The transmission assembly 31 also includes a first support column 314 and a second support column 315. The first support column 314 and the second support column 315 are spaced apart along the second direction Y on the traveling device 50. The height of the first support column 314 is lower than the height of the second support column 315. This causes the transmission belt 311 to be inclined along the second direction Y and the third direction Z. A first horizontal segment 316 and a second horizontal segment 317 are formed at both ends of the transmission belt 311 of the transmission assembly 31. The first horizontal segment 316 is located between the second horizontal segment 317 and the traveling device 50 along the third direction Z. This facilitates the docking of the first horizontal segment 316 with the screening assembly 20 and the second horizontal segment 317 with the storage assembly 32.

[0074] In this embodiment, see Figure 10The storage component 32 includes a bottom wall 321, a first side wall 322, and two second side walls 323. The bottom wall 321, the first side wall 322, and the two second side walls 323 form a storage cavity 324, which is used to receive Coptis chinensis transmitted by the transmission component 31. The first side wall 322 is located at one end of the bottom wall 321 near the transmission component 31, and the end of the first side wall 322 away from the bottom wall 321 is correspondingly located to the transmission component 31. The two second side walls 323 are located on both sides of the bottom wall 321 along the second direction Y. The two second side walls 323 are respectively connected to the two ends of the first side wall 322. The ends of the two second side walls 323 away from the first side wall 322 form an outlet 326 communicating with the storage cavity 324. An inlet 325 communicating with the storage cavity 324 is formed between the first side wall 322 and the two second side walls 323. Thus, the Coptis chinensis transported by the transmission component 31 can directly enter the storage cavity 324 through the inlet 325 formed by the first sidewall 322, so as to temporarily store the Coptis chinensis during the harvesting process. After harvesting, the Coptis chinensis can be directly discharged from the storage cavity 324 through the outlet 326, thereby improving the transfer efficiency of the Coptis chinensis.

[0075] In one embodiment, the storage component 32 is rotatably configured relative to the transmission component 31 to receive or discharge Coptis chinensis from the outlet 326. Thus, during harvesting, the storage component 32 is in the receiving position, and its bottom wall 321 is tilted upwards in a third direction (Z) away from the transmission component, ensuring that the Coptis chinensis does not fall from the outlet 326 during the process of receiving it. After harvesting, the Coptis chinensis can be discharged from the outlet 326 by rotating the storage component 32, achieving high transfer efficiency.

[0076] Specifically, the storage component 32 can be rotated manually or automatically.

[0077] In one embodiment, see Figure 10 The storage component 32 also includes a support portion 327. The support portion 327 is connected to the end of the bottom wall 321 opposite to the transmission component 31. The traveling device 50 also includes a second pivot 55, a connecting arm 54, and a third pivot 56. The second pivot 55 is connected to the support plate 51. The third pivot 56 is connected to the support portion 327. The two ends of the connecting arm 54 are rotatably connected to the second pivot 55 and the third pivot 56, respectively. Thus, when the storage component 32 is in the receiving position, the connecting arm 54 can reliably support the bottom wall 321 through the support portion 327, so that the bottom wall 321 is in an inclined state. After harvesting, by driving the connecting arm 54 to rotate around the second pivot 55, the storage component 32 can be rotated relative to the support plate 51, thereby discharging the Coptis chinensis from the discharge port 326.

[0078] The specific embodiments described above do not constitute a limitation on the scope of protection of this application. Any other corresponding changes and modifications made based on the technical concept of this application should be included within the scope of protection of the claims of this application.
