Description

Technical Field

[0001] This invention belongs to the field of agricultural machinery technology, and in particular relates to an adaptive adjustable candied mustard green leaf removal device and a candied mustard green harvester. 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] While existing mustard green harvesters can complete the harvesting operation, the cutting blades typically cut horizontally at the top of the mustard greens, leaving a significant amount of leaves at the top and around the top of most harvested mustard greens. During the subsequent leaf removal process, the leaf removal device cannot adaptively adjust to the size and irregular shape of the mustard greens during the harvesting period due to the irregular growth shape and inconsistent size of the mustard green stems, as well as the random distribution of the leaves. This results in poor leaf removal efficiency. Summary of the Invention

[0019] Please see Figures 1 to 5 It 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.

Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of the invention.

[0020] 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.

[0021] In this embodiment, please refer to Figures 1 to 5 The present invention provides an adaptive adjustment device for removing leaves from mustard greens, comprising: Mounting bracket 11, with a mounting cavity 111 provided along the height direction of the mounting bracket 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.

[0022] The design of the mounting frame 11, multiple adjustment components 12, inner cylinder 13, flexible component 14 and drive component 15 enables 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 allowing for non-destructive leaf removal. Driven by the drive component 15, the inner cylinder 13 or the mounting bracket 11 is rotated, and the mustard greens are put into the input end of the conveying leaf removal channel 131. The mustard greens are pushed within the conveying leaf removal channel 131, and the mustard greens are conveyed from the input end to the output end of the conveying leaf removal channel 131 to remove the leaves. The mustard greens adaptively expand the vertical plate 121 within the conveying leaf removal channel 131, so as to accommodate mustard greens of different sizes and irregular shapes. The combined action of the first flexible component 141 and the second flexible component 142 continuously pushes, rubs, and squeezes the mustard greens, and the resulting tumbling and mutual rubbing can adapt to the leaves randomly distributed on the top and around the top of the mustard greens, thereby completely removing the residual leaves on the top and around the top of the mustard greens, avoiding the waste of labor costs caused by rework. Finally, the mustard greens are output from the bottom of the conveying leaf removal channel 131. The first flexible component 141 and the second flexible component 142 have a certain degree of elasticity and buffering effect, which can reduce the hard collision and mechanical damage to the surface of the mustard greens during cleaning and conveying, and maintain the appearance of the mustard greens.

[0023] In this embodiment, please refer to Figures 1 to 4 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.

[0024] 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.

[0025] In this embodiment (not illustrated), each of the adjusting components 12 has at least one vertical plate 121, and at least one vertical plate 121 is arranged adjacent to each other along the central axis of the mounting cavity 111. When there are two or more vertical plates 121, the length direction of the vertical plates 121 is parallel to the central axis of the mounting cavity 111, and the two ends of adjacent vertical plates 121 are in contact. Adjacent vertical plates 121 float independently radially, so that when the leaves of continuously conveyed mustard greens are removed, adjacent mustard greens do not affect each other in the conveying and leaf removal channel 131.

[0026] In this embodiment, please refer to Figure 1 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 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, and the mounting bracket 11 is fixedly mounted on the frame.

[0027] 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.

[0028] In this embodiment, please refer to Figure 2A plurality of first flexible members 141 arranged on the outer wall of the inner cylinder 13 are spaced apart along their own axial and circumferential directions. A plurality of second flexible members 142 arranged on the inner wall of the outer cavity 123 are spirally arranged 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. At this time, the inner cylinder 13 is fixedly installed on the cross brace on the frame, and the mounting frame 11 is rotatably installed on the frame. The height of the cross brace is greater than the size of the largest cabbage head, so that the cabbage heads after leaf removal can be transferred along the length direction of the conveyor plate.

[0029] 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.

[0030] In this embodiment, please refer to Figure 2 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.

[0031] In this embodiment, please refer to Figure 5 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.

[0032] 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 14111. 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 mounting 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.

[0033] In this embodiment, please refer to Figure 5 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 replacement frequency and maintenance costs.

[0034] 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.

[0035] In this embodiment, please refer to Figure 1 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 horizontal end of the baffle is set on the frame or 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 horizontal end of the baffle is set on the inner cylinder 13.

[0036] 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 or the mounting frame 11.

[0037] In this embodiment, please refer to Figures 1 to 5 A candied mustard green harvester, including the aforementioned adaptive adjustable candied mustard green leaf removal device.

[0038] Working principle: The inner cylinder 13 or the mounting frame 11 is driven to rotate by the drive component 15. The cabbage head is put into the input end of the leaf removal channel 131. The cabbage head will be pushed in the leaf removal channel 131 and the cabbage head will be conveyed from the input end to the output end of the leaf removal channel 131. The cabbage head will adaptively expand the vertical plate 121 in the leaf removal channel 131, so as to accommodate cabbage heads of different sizes and irregular shapes. The cabbage head is continuously pushed, rubbed and squeezed by the first flexible component 141 and the second flexible component 142. The resulting tumbling and mutual rubbing can adapt to the randomly distributed leaves on the top and around the top of the cabbage head, so as to completely remove the residual leaves on the top and around the top of the cabbage head. Finally, it is output from the bottom of the leaf removal channel 131. The first flexible component 141 and the second flexible component 142 have a certain elasticity and buffering effect, which can reduce the hard collision and mechanical damage to the surface of the cabbage head during cleaning and transportation, and maintain the appearance of the cabbage head.

[0039] In summary, the present invention, through the design of the mounting frame 11, multiple adjustment components 12, inner cylinder 13, flexible component 14 and drive component 15, enables the removal of leaves to adapt to different sizes and irregular shapes of mustard greens to thoroughly remove residual leaves from the top and sides of the mustard greens, and also to remove leaves without damage. Driven by the drive component 15, the inner cylinder 13 or the mounting bracket 11 is rotated, and the mustard greens are put into the input end of the conveying leaf removal channel 131. The mustard greens are pushed within the conveying leaf removal channel 131, and the mustard greens are conveyed from the input end to the output end of the conveying leaf removal channel 131 to remove the leaves. The mustard greens adaptively expand the vertical plate 121 within the conveying leaf removal channel 131, so as to accommodate mustard greens of different sizes and irregular shapes. The combined action of the first flexible component 141 and the second flexible component 142 continuously pushes, rubs, and squeezes the mustard greens, and the resulting tumbling and mutual rubbing can adapt to the leaves randomly distributed on the top and around the top of the mustard greens, thereby completely removing the residual leaves on the top and around the top of the mustard greens, avoiding the waste of labor costs caused by rework. Finally, the mustard greens are output from the bottom of the conveying leaf removal channel 131. The first flexible component 141 and the second flexible component 142 have a certain degree of elasticity and buffering effect, which can reduce the hard collision and mechanical damage to the surface of the mustard greens during cleaning and conveying, and maintain the appearance of the mustard greens. Therefore, this invention effectively overcomes the various shortcomings of the prior art and has high industrial application value.

[0040] 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.
