Description

Technical Field

[0001] This invention belongs to the field of agricultural machinery technology, and in particular relates to a mustard green harvester and harvesting method with a variable diameter leaf removal mechanism. Background Technology

[0002] The scientific name for mustard tuber is *Vitex negundo*, which is the raw material for making pickled mustard tuber. It is mainly cultivated in Chongqing, Sichuan, Zhejiang, Guizhou, and Yunnan provinces, with Fuling pickled mustard tuber from Fuling District of Chongqing being particularly famous. Grown in the soil, it consists of leaves, a modified stem (commonly known as the tuber head), and a root. The above-ground part is 60-80cm tall, with the tuber head located at the lower part of the above-ground portion. The leaves grow on the tuber head, numbering more than ten; the root is located underground and is 20-30cm long.

[0003] Traditionally, harvesting mustard greens is mostly done manually. First, a sickle is used to cut the connection between the mustard green head and the root. Then, holding the head in one hand and a knife in the other, multiple leaves are peeled off one by one before being placed in a basket. Because mature mustard greens are heavy, the head needs to be constantly rotated during the peeling process, making it very laborious and inefficient. Furthermore, while existing harvesting equipment can complete the harvesting operation, the cutting blade typically cuts horizontally at the top of the mustard green head. This results in a significant amount of leaves remaining at the top and around the top of most mustard greens after harvest. During the subsequent leaf removal process, due to the irregular shape and size of the mustard green stems during the harvest season, and the random distribution of leaves, the leaf removal device cannot adaptively adjust to the size and irregular shape of the crop, leading to poor leaf removal results. Summary of the Invention

[0004] In view of the shortcomings of the prior art described above, the purpose of this invention is to provide a mustard greens harvester and harvesting method with a variable diameter leaf removal mechanism, which solves the problems of low efficiency of manual harvesting and the inability of equipment harvesting to adaptively adjust leaf removal according to crop size and irregular shape in the prior art.

The feeding auger is rotatably connected to the cutting table and is located behind the feeding section; The feeding part is rotatably connected to the cutting table. When the feeding part is in motion, it feeds the vegetable head cut by the cutting part toward the feeding auger.

[0011] Optionally, the material transfer assembly includes a material transfer cylinder, a material receiving plate, and a material transfer power source; The material transfer cylinder has a groove on the side facing the front end of the frame, and multiple material transfer slots are arranged circumferentially along the inner wall of the groove. Each material transfer slot is provided with a baffle plate facing the rotation direction of the material transfer cylinder. The rotation axis of the material transfer cylinder is parallel to the front-back direction of the frame and is driven to rotate by the material transfer power source. The receiving plate is inclined at the front and high at the back on the frame to transport the vegetable heads that fall from the transfer trough to the storage tank.

[0012] Optionally, the material transfer mechanism further includes a self-shaking component, which is disposed around the material transfer plate; Each self-shaking component includes a support body, a strut, and a self-shaking spring. The support body is fixedly connected to the side wall of the intermediate through groove, and the strut is fixedly connected to the side of the transfer plate. The support body is provided with a vertically upward sliding groove that slides with the strut.

[0013] Optionally, the conveying mechanism is rotatably connected to the intermediate through groove via a lifting shell, and the distance between the leaf-cutting and root-cutting mechanism and the ground is controlled by a lifting component. The conveying mechanism includes a lifting belt, a first drive shaft, a second drive shaft, and a lifting power source. The first drive shaft and the second drive shaft are rotatably connected to both ends of the lifting shell, and the lifting belt is wound around the first drive shaft and the second drive shaft. The lifting belt is provided with a plurality of baffles to prevent the cabbage heads from sliding downward. The lifting power source is used to drive the first transmission shaft to rotate, thereby driving the lifting belt to rotate and transport the mustard greens fed by the root cutting component to the input end of the leaf removal mechanism.

[0014] A harvesting method for a mustard greens harvester with a variable diameter leaf-removing mechanism, comprising the aforementioned mustard greens harvester with a variable diameter leaf-removing mechanism, including the following steps: Cutting steps: The moving chassis moves forward, the leaf-cutting power source drives the leaf-cutting cylinder to rotate in the direction of travel of the moving chassis, the leaf-cutting stick breaks up the leaves on the top of the green vegetable, and as the moving chassis moves forward, the root-cutting component cuts the vegetable root and feeds it into the conveying mechanism, and then conveys it to the input end of the leaf-removing mechanism through the conveying mechanism. Leaf removal step: The inner cylinder or the mounting frame is driven to rotate by the drive component. The green vegetable head is pushed from the input end to the output end of the conveying leaf removal channel. The green vegetable head adaptively expands the vertical plate in the conveying leaf removal channel to accommodate green vegetable heads of different sizes and irregular shapes. The residual vegetable leaves on the top and around the green vegetable head are completely removed by the combined action of the first flexible member and the second flexible member. Transfer steps: The defoliated mustard greens are received from the output end of the defoliation channel via the transfer plate. As the defoliated mustard greens roll from the input end to the output end of the transfer plate, the residue falls to the ground through the slag trough. The transfer assembly then transports the defoliated mustard greens output from the outlet of the transfer plate to the storage tank above the frame.

[0015] As described above, the pickled mustard greens harvester and harvesting method with a variable diameter leaf removal mechanism of the present invention have at least the following beneficial effects: 1. As the mobile chassis moves forward, the leaf-beating cylinder of the leaf-beating assembly rotates driven by the leaf-beating power source. The leaf-beating rod breaks up the leaves on the top of the mustard greens and uses the centrifugal force of rotation to throw the broken leaves forward. Then, the root-cutting assembly cuts off the roots of the mustard greens, separating the mustard greens from the soil. The cut mustard greens are lifted by the conveying mechanism and transported to the input end of the leaf-removing mechanism. After the leaf-removing mechanism thoroughly removes the leaves on the top and around the top of the mustard greens, they fall into the transfer plate. The transfer plate is inclined and has a slag-straining trough. During the sliding process, the slag is separated by gravity. The transfer assembly lifts the mustard greens and transports them to the storage pool above the frame. This makes the mustard green harvesting process continuous and integrated, improves harvesting efficiency, and solves the problem of low efficiency in manual harvesting.

[0016] 2. Through the design of the mounting frame, multiple adjustment components, inner cylinder, flexible components and drive components, it can adapt to different sizes and irregular shapes of mustard greens during the leaf removal process to thoroughly remove the residual leaves on the top and sides of the mustard greens, and can also remove leaves without damage. The drive assembly rotates the inner cylinder or mounting frame, conveying the mustard greens to the input end of the leaf removal channel via the conveying mechanism. The mustard greens are pushed within the channel, moving from the input to the output. Within the channel, the vertical plates automatically expand to accommodate mustard greens of varying sizes and irregular shapes. The combined action of the first and second flexible components continuously agitates, rubs, and squeezes the mustard greens, causing them to tumble and rub against each other. This process effectively removes any remaining leaves from the top and surrounding areas, preventing rework and wasting labor costs. Finally, the mustard greens are output from the bottom of the channel. The first and second flexible components provide elasticity and cushioning, minimizing hard impacts and mechanical damage to the mustard greens during cleaning and conveying, thus maintaining their appearance.

[0020] The following specific embodiments illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification.

[0021] Please see Figures 1 to 13It should be understood that the structures, proportions, sizes, etc., depicted in the accompanying drawings are merely for illustrative purposes to aid those skilled in the art and to facilitate understanding. They are not intended to limit the scope of the invention and therefore have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, without affecting the effectiveness and purpose of the invention, should still fall within the scope of the technical content disclosed herein. Furthermore, the terms "upper," "lower," "left," "right," "middle," and "one" used in this specification are merely for clarity and not intended to limit the scope of the invention. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of the invention.

[0022] The following embodiments are for illustrative purposes only. These embodiments can be combined and are not limited to the content shown in any single embodiment below.

[0023] In this embodiment, please refer to Figures 1 to 13 This invention provides a mustard greens harvester with a variable diameter leaf removal mechanism, comprising: The mobile chassis 2, leaf and root cutting mechanism 3, leaf removal mechanism 1, and material transfer mechanism 5 are provided. The mobile chassis 2 includes a frame 21 with a central through groove along the front-to-back direction. The central through groove can be stepped from front to back. The mobile chassis 2 can be tracked or wheeled. The frame 21 can be equipped with a driver's cab and a control console for personnel operation.

[0024] The leaf-cutting and root-cutting mechanism 3 is located in front of the intermediate through groove. The leaf-cutting and root-cutting mechanism 3 includes a leaf-cutting component 31 and a root-cutting component 32. The leaf-cutting component 31 and the root-cutting component 32 are connected to the intermediate barrel groove of the frame 21 through the conveying mechanism 4. The leaf-cutting component 31 is located in front of the root-cutting component 32. The leaf-cutting component 31 includes a leaf-cutting cylinder 311 and a leaf-cutting power source 312. The leaf-cutting cylinder 311 is laterally rotatably connected to the front of the cutting table 321 of the cutting component via a forward extension arm 313, and is driven by the leaf-cutting power source 312 to rotate in the direction of travel of the mobile chassis 2 so as to fly the crushed vegetable leaves in the direction of travel. This can effectively keep the root-cutting component 32 clean, and can also crush the thrown vegetable leaves multiple times during the movement of the mobile chassis 2, which is more conducive to returning to the field. The leaf-beating power source 312 includes, but is not limited to, a motor. The leaf-beating cylinder 311 is equipped with multiple leaf-beating rods 314, which are spaced apart axially and circumferentially along the leaf-beating cylinder 311. The leaf-beating rods 314 can be made of silicone rubber, and their hardness is set to be greater than the vegetable leaves but less than the mustard greens, allowing them to remove the upper part of the mustard greens without damaging them. This effectively breaks up the leaves and returns them to the field without damaging the surface of the mustard greens. In another embodiment, the leaf-beating assembly 31 also includes two sliding frames 315 and a lifting device 316. The two sliding frames 315 are slidably engaged with the two forward extension arms 313 respectively. The two ends of the leaf-beating cylinder 311 are rotatably connected to the sliding frames 315. The lifting device 316 is used to control the distance between the sliding frames 315 and the ground to accommodate different growth stages of the mustard greens. There can be two lifting devices 316, each independently controlling one of the two sliding frames 315. The fixed end and telescopic end of the lifting device 316 are respectively installed on the forward extension arm 313 and the sliding frame 315. The lifting device 316 can be an electric push rod, a hydraulic cylinder, or a pneumatic cylinder. A cutting structure can also be provided between the two sliding frames and below the leaf-beating assembly to horizontally cut the upper part of the mustard greens that have been processed by the leaf-beating assembly and are still growing in the soil. This can be an existing structure.

[0025] The conveying mechanism 4 is inclined at the front and high at the back, located behind the root-cutting component 32, to convey the mustard greens fed by the root-cutting component 32 to the input end of the leaf-removing mechanism 1. The leaf-removing mechanism 1 is located below the output end of the conveying mechanism 4. The leaf-removing mechanism 1 can adapt to different sizes and irregular shapes of mustard greens, so as to separate the residual leaves on the top and around the top of the mustard greens from the mustard greens, thereby achieving thorough removal.

[0026] The material transfer mechanism 5 includes a material transfer plate 51 and a material transfer assembly 52. ​​The material transfer plate 51 is inclined at the front and lower at the back in the middle through groove, and the input end is located below the output end of the leaf removal mechanism 1. The material transfer plate 51 is provided with a plurality of slag leakage grooves 511, which are evenly arranged laterally along the frame 21. When the material transfer assembly 52 is activated, it transports the leaf-removed vegetable heads output from the outlet of the material transfer plate 51 to the storage tank 22 above the frame 21.

[0027] As the mobile chassis 2 moves forward, the leaf-beating cylinder 311 of the leaf-beating assembly 31 is driven to rotate by the leaf-beating power source 312. The leaf-beating rod 314 breaks up the leaves on the top of the mustard greens and throws the broken leaves forward using the centrifugal force of rotation. Then, the root-cutting assembly 32 cuts off the roots of the mustard greens, separating the mustard greens from the soil. The cut mustard greens are lifted by the conveying mechanism 4 and transported to the input end of the leaf-removing mechanism 1. After the leaf-removing mechanism 1 thoroughly removes the leaves from the top and surrounding area of ​​the mustard greens, they fall into the transfer plate 51. The transfer plate 51 is inclined and has a slag-leakage trough 511. During the sliding process, the slag is separated by gravity. The transfer assembly 52 lifts the mustard greens and transports them to the storage pool 22 above the frame 21, making the mustard green harvesting process continuous and integrated, improving harvesting efficiency, and thus solving the problem of low efficiency of manual harvesting.

[0028] In this embodiment, please refer to Figures 2 to 7 The leaf removal mechanism 1 includes a mounting frame 11, which is vertically arranged above the input end of the transfer plate 51, and has a mounting cavity 111 along the height direction of the mounting frame 11; Multiple adjustment components 12 are located within the mounting cavity 111 and are evenly arranged circumferentially along the sidewall of the mounting cavity 111. Each of the adjustment components 12 includes a vertical plate 121 and at least one adaptive adjustment part 122. The vertical plate 121 is connected to the side wall of the mounting cavity 111 through at least one adaptive adjustment part 122. The vertical plates 121 of the plurality of adjustment components 12 enclose an outer cavity 123. Inner cylinder 13, the inner cylinder 13 is located in the mounting cavity 111, the central axis of the inner cylinder 13 is collinear with the central axis of the mounting cavity 111, and the outer wall of the inner cylinder 13 and the inner wall of the outer cavity 123 formed by the vertical plates 121 of the multiple adjustment components 12 together form a conveying leaf removal channel 131. The flexible component 14 includes a first flexible element 141 and a second flexible element 142. A plurality of first flexible elements 141 are disposed on the outer wall of the inner cylinder 13, and a plurality of second flexible elements 142 are disposed on the inner wall of the outer cavity 123. The first flexible elements 141 and the second flexible elements 142 are disposed opposite to each other, and there is a gap between the ends of the first flexible elements 141 and the second flexible elements 142 away from the mounting end. The drive assembly 15 is used to drive the inner cylinder 13 or the mounting bracket 11 to rotate to generate a thrust along the axial direction of the inner cylinder 13 or the mounting bracket 11, so that the vegetable heads are conveyed from the input end of the conveying leaf removal channel 131 to the output end.

[0029] The design of the mounting frame 11, multiple adjusting components 12, inner cylinder 13, flexible component 14, and drive component 15 allows for the removal of leaves from different sizes and irregular shapes of mustard greens, ensuring thorough removal of residual leaves from the top and sides of the mustard greens, while also enabling non-destructive leaf removal. The drive component 15 drives the inner cylinder 13 or mounting frame 11 to rotate, conveying the mustard greens to the input end of the leaf removal channel 131 via the conveying mechanism 4. The mustard greens are then pushed within the channel, moving from the input to the output. The vertical plate 121 automatically expands within the channel, accommodating different sizes and irregular shapes of mustard greens. The combined action of the first flexible component 141 and the second flexible component 142 further enhances the leaf removal process. The continuous stirring, friction, and squeezing of the turnips cause them to tumble and rub against each other, allowing them to adapt to the randomly distributed leaves on and around the top of the turnips. This thoroughly removes any remaining leaves from the top and sides of the turnips, avoiding the waste of labor costs caused by rework. The turnips are then output from the bottom of the leaf removal channel 131. The first flexible component 141 and the second flexible component 142 have a certain degree of elasticity and cushioning, which reduces hard impacts and mechanical damage to the surface of the turnips during cleaning and transportation, thus maintaining the appearance of the turnips.

[0030] In this embodiment, please refer to Figures 3 to 6 The adaptive adjustment unit 122 includes a seat 1221, which is fixedly connected to the side wall of the mounting cavity 111 of the mounting bracket 11; An adjusting rod 1222 is perpendicular to and fixedly connected to the vertical plate 121 along its length. The base 1221 is provided with an adjusting groove 1223 that slides with the adjusting rod 1222. When removing leaves, the cabbage head adaptively expands the vertical plate 121 within the conveying leaf removal channel 131. The adjusting rod 1222 slides within the adjusting groove 1223 in a direction away from the central axis of the mounting cavity 111 to adapt to cabbage heads of different sizes. An elastic element 1224 is disposed between the end of the seat 1221 and the adjusting rod 1222 for resetting the vertical plate 121 toward the central axis of the mounting cavity 111. The elastic element 1224 includes a spring that is sleeved on the adjusting rod 1222.

[0031] During operation, when the drive assembly 15 drives the inner cylinder 13 or the mounting bracket 11 to rotate, the vegetable heads are conveyed from the input end to the output end of the conveying and leaf-removing channel 131. The vegetable heads adaptively expand the vertical plate 121 radially outward. The vertical plate 121 drives the adjusting rod 1222 to slide away from the central axis of the mounting cavity 111 within the adjusting groove 1223, thus adapting to different sized vegetable heads. At this time, the elastic element 1224 is compressed. The elastic force of the elastic element 1224 is used to reset the vertical plate 121 towards the central axis of the mounting cavity 111, preparing it for the next conveying and leaf-removing of vegetable heads.

[0032] To ensure that adjacent mustard greens do not interfere with each other within the conveying and leaf-removing channel 131, each of the adjusting components 12 has at least one vertical plate 121, which is arranged adjacent to each other along the central axis of the mounting cavity 111. When there are two or more vertical plates 121, their length direction is parallel to the central axis of the mounting cavity 111, and the ends of adjacent vertical plates 121 are in contact. Adjacent vertical plates 121 independently float radially to achieve diameter variation, so that when continuously conveying mustard greens for leaf removal, adjacent mustard greens do not interfere with each other within the conveying and leaf-removing channel 131.

[0033] In this embodiment, please refer to Figure 3 and Figure 4 The inner cylinder 13 has several first flexible members 141 arranged spirally along its axial direction on its outer wall. The outer cavity 123 has several second flexible members 142 arranged at intervals along its axial and circumferential directions on its inner wall. The inner cylinder 13 is driven to rotate by the drive assembly 15 to transport the cabbage heads from the input end to the output end of the conveying and leaf-removing channel 131. The drive assembly 15 includes, but is not limited to, a motor, and its output shaft is coaxially and fixedly connected to the inner cylinder 13. At this time, the inner cylinder 13 is rotatably mounted on a cross brace on the frame 21, and the mounting bracket 11 is fixedly mounted on the frame 21. The height of the cross brace is greater than the size of the largest cabbage head, allowing the de-leafed cabbage heads to be transported along the length of the conveyor plate.

[0034] When the inner cylinder 13 is driven to rotate by the drive assembly 15, the spirally arranged first flexible member 141 generates a pushing force along the axial direction of the inner cylinder 13 on the mustard greens in the conveying leaf removal channel 131, ensuring that the mustard greens move stably and continuously from the input end to the output end of the conveying leaf removal channel 131. Under the push of the first flexible member 141, the downward-moving mustard greens collide, squeeze, and rub against the second flexible member 142. At the same time, the mustard greens themselves will also tumble in the conveying leaf removal channel 131, so that the residual leaves on the top and sides of the mustard greens can be effectively and thoroughly removed.

[0035] Alternatively, a plurality of the first flexible members 141 disposed on the outer wall of the inner cylinder 13 are arranged at intervals along their own axial and circumferential directions, and a plurality of the second flexible members 142 disposed on the inner wall of the outer cavity 123 are arranged spirally along the axial direction of the outer cavity 123. The mounting frame 11 is driven to rotate by the driving assembly 15 to transport the cabbage heads from the input end to the output end of the conveying leaf removal channel 131. In this case, the inner cylinder 13 is fixedly mounted on the cross brace on the frame 21, and the mounting frame 11 is rotatably mounted on the frame 21. The drive assembly 15 drives the mounting frame 11 to rotate, and the second flexible element 142 arranged in a spiral on its inner wall rotates accordingly. The friction between the second flexible element 142 and the mustard greens generates an axial thrust, which stably pushes the mustard greens from the input end of the conveying leaf removal channel 131 to the output end. When the mustard greens are pushed and rolled by the spirally arranged second flexible element 142 on the vertical plate 121 inside the mounting frame 11, they collide, squeeze and flexibly rub against the first flexible element 141 on the inner cylinder 13 in the conveying leaf removal channel 131, thereby effectively and thoroughly removing the residual leaves on the top and around the mustard greens.

[0036] The drive assembly 15 includes a first gear 151, a second gear 152, and a drive member 153. The first gear 151 is coaxially fixedly engaged with the mounting frame 11. The first gear 151 meshes with the second gear 152 for transmission. The output power of the drive member 153 is transmitted to the first gear 151 through the second gear 152 to drive the mounting frame 11 to rotate. The drive member 153 includes, but is not limited to, a motor. The drive member 153 drives the second gear 152 to rotate, and the second gear 152 meshes with the first gear 151 for transmission. The second gear 152 drives the first gear 151 to rotate, which in turn drives the mounting frame 11 to rotate, thereby driving the second flexible member 142, which is spirally arranged on the inner vertical plate 121 of the mounting frame 11, to rotate.

[0037] In this embodiment, please refer to Figures 3 to 7 The first flexible member 141 and the second flexible member 142 have the same structure; The first flexible member 141 and the second flexible member 142 are provided with a plurality of annular protrusions 1414, which are equally spaced and / or unequally spaced along their own axial direction. The annular protrusions 1414 not only increase the frictional force of axial pushing, effectively preventing the vegetable head from slipping and ensuring stable conveying efficiency, but also change the force point of the vegetable head from continuous surface contact to discrete point contact and line contact when it comes into contact with the first flexible member 141 and the second flexible member 142, thereby improving the cleaning effect and uniformity.

[0038] The first flexible member 141 includes an installation section 1411, a transition section 1412, and a leaf removal section 1413. The end of the installation section 1411 is provided with a flange structure. The diameter of the flange is larger than the diameter of the installation section 1411. It is used to provide a limit when it mates with the installation hole on the inner cylinder 13, so that it can be installed easily and replaced easily, and also increase the contact surface and improve the connection stability. The transition section 1412 is connected to the mounting section 1411 and the blade removal section 1413 at both ends, and the diameter of the transition section 1412 is larger than the diameter of the mounting section 1411. The two ends can be tapered or arc-shaped to achieve a smooth transition from the mounting platform to the blade removal section 1413 and reduce stress concentration. The leaf-removing section 1413 is provided with a plurality of annular protrusions 1414, which are arranged at equal and / or unequal intervals along their own axial direction. The leaf-removing section 1413 may be frustoconical or conical.

[0039] The first flexible component 141 and the second flexible component 142 are silicone rods or rubber rods. Silicone has good elasticity and flexibility. When a hard vegetable head collides or is squeezed against the silicone rod, the silicone rod can effectively absorb the impact energy through its own deformation, greatly reducing the risk of dents and scratches on the material surface. Furthermore, silicone material has excellent wear resistance and tear resistance, which can significantly extend the service life of the first flexible component 141 and the second flexible component 142, reducing the replacement frequency and maintenance costs.

[0040] The hardness of the first flexible member 141 and the second flexible member 142 is set to be greater than that of the vegetable leaves and less than that of the cabbage head, so that the first flexible member 141 and the second flexible member 142 can remove the vegetable leaves remaining on the cabbage head without damaging the cabbage head.

[0041] It also includes a limiting component 16, which includes a first limiting member 141. The first limiting member 141 is used to restrict the upward movement of the vegetable head when it is located at the input end of the conveying leaf removal channel 131. The limiting component 16 can be a baffle and is L-shaped. When the driving component 15 drives the inner cylinder 13 to rotate, the baffle is set on the frame 21 or the mounting frame 11 to provide a reaction force to restrict the upward movement, so that the vegetable head moves along the axial direction of the inner cylinder 13 under the rotation of the driving component 15. When the driving component 15 drives the mounting frame 11 to rotate, the baffle is set on the inner cylinder 13.

[0042] The second limiting member 142 is used to prevent the mustard greens from falling when they are initially placed into the input end of the conveying leaf removal channel 131. The second limiting member 142 can be a ring structure and is set on the frame 21 or the mounting frame 11.

[0043] In this embodiment, please refer to Figures 8 to 10 The root cutting assembly 32 includes a cutting table 321, a cutting part 322, a feeding auger 323, a feeding part 324, and a driving part 325; The cutting table 321 is connected to the input end of the conveying mechanism 4. Multiple leaf-draining grooves 3211 are arranged laterally along the cutting table 321 for discharging broken leaves and soil. The cutting table 321 can be arranged with a lower front and a higher back to facilitate the arrangement of the conveying mechanism 4. The cutting part 322 is horizontally arranged in front of the cutting table 321. The cutting part 322 includes a fixed blade tooth 3221 and a cutting blade tooth 3222. When the cutting blade tooth 3222 moves, it reciprocates relative to the fixed blade tooth 3221 to cut the vegetable root. During the reciprocating motion, the cutting blade tooth 3222 and the fixed blade tooth 3221 intersect each other to complete the cutting action. The feeding auger 323 is rotatably connected to the cutting table 321 and is located behind the feeding part 324. The feeding auger 323 concentrates the heads of the vegetables in the middle, and a lever 3231 can be set in the middle position to facilitate pushing the vegetable heads towards the output end of the cutting table 321. The feeding part 324 is rotatably connected to the cutting table 321. When the feeding part 324 is in operation, it feeds the vegetable head cut by the cutting part 322 toward the feeding auger 323. The feeding part 324 includes a rotating frame 3241 rotatably connected to the cutting table 321 and a plurality of feeding rods 3242. The plurality of feeding rods 3242 are evenly arranged around the rotating frame 3241 at intervals. Each feeding rod 3242 is provided with a plurality of feeding teeth 3243 along its own axial direction. When the rotating frame 3241 moves, it feeds the vegetable head cut by the cutting part 322 toward the feeding auger 323. The cutting teeth 3222 of the cutting section 322, the feeding auger 323 and the feeding section 324 are all driven by the power of the driving section 325.

[0044] The drive unit 325 includes a rotating disk 3251 coaxially fixed to one end of the feeding auger 323, a first pull rod 3252 rotatably connected to the side edge of the rotating disk 3251, a fixed post 3253 disposed on the side of the cutting table 321, a rotating cylinder 3254 coaxially rotatably connected to the fixed post 3253, a second pull rod 3255, and a drive power source 3256. Two protruding fingers 32541 are provided on the side wall of the rotating cylinder 3254, and the two protruding fingers 32541 are arranged in a V-shape. One of the protruding fingers 32541 is rotatably connected to the other end of the first pull rod 3252. Next, the second pull rod 3255 is rotatably connected to the other extended finger 32541 and the cutting blade tooth 3222 respectively. The output power of the drive power source 3256 is transmitted to the feeding auger 323 through the gear set 3257. The drive power source 3256 includes, but is not limited to, a motor. A drive gear is provided on the output shaft of the motor. A transmission gear is coaxially fixed at the other end of the feeding auger 323. The drive gear and the transmission gear mesh and transmit power. The rotating frame 3241 and the feeding auger 323 are transmitted through an annular transmission member 3258. The annular transmission member 3258 can be a pulley set or a sprocket set.

[0045] The power source 3256 drives the drive gear to mesh with the transmission gear, transmitting power to the feeding auger 323, causing it to rotate. The feeding auger 323 drives the feeding part 324 to rotate via the annular transmission component 3258. The feeding rod 3242 and feeding teeth 3243 on the feeding part 324 push the cut vegetable heads backward. The rotating disk 3251 at one end of the feeding auger 323 rotates synchronously with the auger. The edge of the rotating disk 3251 is connected to an extended finger 32541 on the rotating cylinder 3254 via the first pull rod 3252. The rotating cylinder 3254 is fitted onto the fixed post 3253. Another extended finger 32541 on the rotating cylinder 3254 is connected to the cutting teeth 3222 via the second pull rod 3255, causing the cutting teeth 3222 to reciprocate relative to the fixed teeth 3221, completing the cutting.

[0046] In this embodiment, please refer to Figure 1 , Figure 11 and Figure 12 The material transfer assembly 52 includes a material transfer cylinder 521, a material receiving plate 522, and a material transfer power source 523, which includes, but is not limited to, a motor. The material transfer cylinder 521 has a groove 5211 on the side facing the front end of the frame 21. Multiple material transfer grooves 5212 are arranged circumferentially along the inner wall of the groove 5211. Each material transfer groove 5212 is provided with a baffle plate 5213 facing the rotation direction of the material transfer cylinder 521. The rotation axis of the material transfer cylinder 521 is parallel to the front-back direction of the frame 21 and is driven to rotate by the material transfer power source 523. The receiving plate 522 is inclined at the front and high at the back on the frame 21 to transport the vegetable heads that fall from the transfer trough 5212 to the storage tank 22.

[0047] After the leaves are removed, the green vegetable heads fall onto the transfer plate 51, where the residue is drained through the slag trough 511. The green vegetable heads then roll backward into the transfer trough 5212 of the transfer cylinder 521. The transfer cylinder 521 is driven to rotate by the transfer power source 523, and it flips upward and is lifted. When it reaches a high position, the green vegetable heads fall off the transfer trough 5212 under the action of gravity and fall onto the receiving plate 522, which is lower in the front and higher in the back. The receiving plate 522 is tilted and guided to slide the green vegetable heads into the storage pool 22 above the frame 21, thus completing the continuous transfer.

[0048] In this embodiment, please refer to Figure 12 and Figure 13 The material transfer mechanism 5 also includes a self-shaking component 53, which is arranged around the material transfer plate 51 so that the material transfer plate 51 can shake up and down while conveying the defoliated green vegetable heads, so that the residue can fall to the ground through the slag hole, thereby keeping the storage tank 22 clean. Each self-shaking component 53 includes a support body 531, a support rod 532, and a self-shaking spring 533. The support body 531 is fixedly connected to the side wall of the intermediate through groove, and the support rod 532 is fixedly connected to the side of the transfer plate 51. The support body 531 is provided with a vertically upward sliding groove 5311 that slides with the support rod 532. The self-shaking spring 533 is disposed between the end of the support body 531 and the support rod 532 to reset the transfer plate 51 to the output end of the leaf removal mechanism 1. The self-shaking spring 533 includes a spring that is sleeved on the support rod 532.

[0049] When the vegetable heads output from the leaf removal mechanism 1 fall onto the transfer plate 51, the impact force generates a downward force, pushing the transfer plate 51 downward and compressing the self-shaking spring 533. As the self-shaking spring 533 elastically releases to reset the transfer plate to the output end of the leaf removal mechanism 1, the leaf-removed vegetable heads are conveyed from the input end to the output end of the transfer plate 51. At the same time, the reciprocating shaking of the self-shaking spring 533 during compression or reset makes it easier for the residue to fall to the ground from the slag hole, reducing adhesion and accumulation.

[0050] In this embodiment, please refer to Figure 2The conveying mechanism 4 is rotatably connected to the intermediate channel through the lifting shell 41, and the distance between the leaf-cutting and root-cutting mechanism 3 and the ground is controlled by the lifting member 42 of the lifting shell 41, so as to switch between use and non-use, and facilitate position change; the lifting member 42 includes a hydraulic cylinder, a pneumatic cylinder or an electric push rod, and the fixed end and the telescopic end of the lifting member 42 are respectively hinged to the lifting shell 41 and the top of the intermediate channel; The conveying mechanism 4 includes a lifting belt 43, a first drive shaft 44, a second drive shaft 45, and a lifting power source. The first drive shaft 44 and the second drive shaft 45 are rotatably connected to both ends of the lifting shell 41, and the lifting belt 43 is wound around the first drive shaft 44 and the second drive shaft 45. The belt input end is located below the output end of the cutting table 321. The lifting belt 43 is provided with a plurality of baffles 46 for preventing the cabbage heads from sliding downward. The surface of the lifting belt 43, the inner wall of the lifting shell 41, and the adjacent baffles 46 together form a conveying and receiving cavity for accommodating the cabbage heads. The lifting power source is used to drive the first transmission shaft 44 to rotate, thereby driving the lifting belt 43 to rotate and transport the mustard greens fed by the root cutting component 32 to the input end of the leaf removal mechanism 1. The lifting power source includes, but is not limited to, a motor.

[0051] In this embodiment, please refer to Figures 1 to 13 A harvesting method for a mustard greens harvester with a variable diameter defoliation mechanism, comprising the aforementioned mustard greens harvester with the variable diameter defoliation mechanism 1, including the following steps: Cutting steps: The moving chassis 2 moves forward, the leaf-cutting power source 312 drives the leaf-cutting cylinder 311 to rotate in the direction of travel of the moving chassis 2, the leaf-cutting stick 314 breaks up the leaves on the top of the green vegetable, and as the moving chassis 2 moves forward, the root-cutting component 32 cuts the vegetable root and feeds it into the conveying mechanism 4, and then conveys it to the input end of the leaf-removing mechanism 1 through the conveying mechanism 4; Leaf removal step: The inner cylinder 13 or the mounting bracket 11 is driven to rotate by the drive component 15. The cabbage head is pushed from the input end to the output end of the conveying leaf removal channel 131. The cabbage head adaptively expands the vertical plate 121 in the conveying leaf removal channel 131 to accommodate cabbage heads of different sizes and irregular shapes. The residual leaves on the top and around the cabbage head are completely removed by the combined action of the first flexible member 141 and the second flexible member 142. Transfer steps: The defoliated vegetable heads are received from the output end of the defoliation channel 131 via the transfer plate 51. As the defoliated vegetable heads roll from the input end to the output end of the transfer plate 51, the residue falls to the ground through the slag trough 511. The transfer assembly 52 then transports the defoliated vegetable heads output from the outlet of the transfer plate 51 to the storage tank 22 above the frame 21.

[0052] In summary, during the forward movement of the mobile chassis 2, the leaf-beating cylinder 311 of the leaf-beating assembly 31 is driven to rotate by the leaf-beating power source 312. The leaf-beating rod 314 breaks up the leaves on the top of the mustard greens, and the centrifugal force of the rotation throws the broken leaves forward. Subsequently, the root-cutting assembly 32 cuts off the roots of the mustard greens, separating the mustard greens from the soil. The cut mustard greens are lifted by the conveying mechanism 4 and transported to the input end of the leaf-removing mechanism 1. After the leaf-removing mechanism 1 thoroughly removes the leaves from the top and surrounding area of ​​the mustard greens, they fall into the transfer plate 51. The transfer plate 51 is inclined and has a slag-straining trough 511. During the sliding process, gravity separates the slag. The transfer assembly 52 lifts the mustard greens and transports them to the storage pool 22 above the frame 21. This makes the mustard green harvesting process continuous and integrated, improving harvesting efficiency and solving the problem of low efficiency in manual harvesting. Therefore, this invention effectively overcomes the various shortcomings of the prior art and has high industrial application value.

[0053] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the invention. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in the present invention should still be covered by the claims of the present invention.
