MODE FOR CARRYING OUT THE INVENTION

[0017] Hereinafter, the technical solution of the present invention will be further described with reference to the accompanying drawings.

[0018] The mini Chinese cabbage processing apparatus disclosed in the present invention includes, as shown in Figure 1, a planetary gear assembly 1, a clamping assembly 2, a root cutting assembly 3, an opening / closing control assembly 4, a leaf sieving assembly 5, and a collection and crushing assembly 6. The clamping assembly 2 is fixedly connected to the planetary part of the planetary gear assembly 1 and is used to clamp the mini Chinese cabbage. During the operation of the planetary gear assembly 1, the clamping assembly 2 moves synchronously with the planetary part of the planetary gear assembly 1, i.e., it rotates and revolves while clamping the mini Chinese cabbage. The root cutting assembly 3 is located below the clamping assembly 2 and is used to cut the roots of the mini Chinese cabbage in the process of the planetary part revolving the clamping assembly 2. Multiple sets of opening / closing control assemblies 4 are provided in total, corresponding to the number of clamping assemblies 2, and are located on the outer circumference of the multiple sets of clamping assemblies 2 and are used to control the clamping assemblies 2 to release the root-cut mini Chinese cabbage. The leaf sieving assembly 5 is located below the root cutting assembly 3 and connected to the clamping assembly 2. It rotates synchronously with the orbit of the clamping assembly 2, separating the roots and leaves of the mini Chinese cabbage. During use, the planetary gear assembly 1 operates, and the clamping assembly 2 moves synchronously with the planetary gears of the planetary gear assembly 1, rotating and revolving while clamping the mini Chinese cabbage. As the clamping assembly 2 revolves while clamping the mini Chinese cabbage and passes the root cutting assembly 3, the root cutting assembly 3 cuts the roots of the mini Chinese cabbage. The clamping assembly 2 continues to move while clamping the trimmed mini Chinese cabbage, and the centrifugal force generated when the clamping assembly 2 rotates while clamping the mini Chinese cabbage separates the leaves of the trimmed mini Chinese cabbage. When the clamping assembly 2 revolves to one side of the opening / closing control assembly 4 while clamping the trimmed mini Chinese cabbage, the opening / closing control assembly 4 controls the clamping assembly 2 to release. The root-trimmed mini Chinese cabbages fall into the leaf sieving assembly 5 and, after being separated by the centrifugal force of rotation, the leaves of the mini Chinese cabbages are dispersed into the leaf sieving assembly 5. The leaf sieving assembly 5 rotates synchronously with the rotation of the clamping assembly 2, and the centrifugal force generated during rotation separates the roots and leaves of the mini Chinese cabbages.The sifted roots and the fine leaves generated during the sifting process fall into the collection and crushing assembly 6, which crushes the roots and fine leaves, and the sifted, complete mini Chinese cabbage leaves are collected.

[0019] As shown in Figures 1 and 2, the planetary gear assembly 1 includes an internal gear ring 11, a support frame 12, a sun gear 13, a planetary external gear ring 14, a first connecting frame 15, a first motor 16, and a planetary frame 55. The support frame 12 is fixedly connected to the bottom of the internal gear ring 11 and provides support. The sun gear 13 is located inside the internal gear ring 11 and is concentric with it. Multiple planetary external gear rings 14 are provided, and the multiple planetary external gear rings 14 are arranged in an annular array around the sun gear 13 and are connected to both the sun gear 13 and the internal gear ring 11 by meshing. The planetary frame 55 is located below the planetary external gear ring 14 and supports the planetary external gear ring 14. The first connecting frame 15 is fixedly connected to the internal gear ring 11, the first motor 16 is fixedly mounted to the first connecting frame 15, and the output shaft of the first motor 16 is fixedly connected to the sun gear 13. The first motor 16 rotates the sun gear 13, which in turn rotates the planetary external gear ring 14, causing the planetary external gear ring 14 to rotate on its own axis. Since the planetary external gear ring 14 is connected to the internal gear ring 11 by meshing with it, it rotates along the inner wall of the internal gear ring 11 while rotating on its own axis, thus performing orbital motion.

[0020] Preferably, as shown in Figure 1, a plurality of positioning frames 17 arranged in an annular array are fixedly connected to the internal tooth ring 11, and the number of positioning frames 17 matches the number of planetary external tooth rings 14. The positioning frames 17 can assist in the installation of the first connection frame 15 and can also function as a positioning reference when assembling the planetary external tooth rings 14. Furthermore, a third connection frame 41 can also be attached to the positioning frames 17.

[0021] As shown in Figures 3 to 8, the clamping assembly 2 includes a connecting ring 21, a second connecting frame 22, a gear frame 23, an upper regulating guide groove 24, an upper tooth plate 25, an upper spring 26, a lower regulating guide groove 27, a lower tooth plate 28, a lower spring 29, a clamping rod 210, a clamping case 211, and a transmission member. The connecting ring 21 is fixedly connected to the inner circumferential wall of the planetary external gear ring 14, and as shown in Figures 10 and 11, mounting holes for attaching the connecting ring 21 are made in the planetary frame 55. As shown in Figure 3, a stepped surface 212 is provided at the bottom of each of the multiple connecting rings 21, and the multiple connecting rings 21 are supported in the mounting holes via the stepped surfaces, the planetary frame 55 supports the planetary external gear ring 14, and the connecting rings 21 are rotatably connected to the planetary frame 55, causing the planetary frame 55 to rotate synchronously during revolution and maintaining the planetary frame 55 in a synchronous rotation state.

[0022] The second connecting frame 22 is fixedly connected to the inner wall of the connecting ring 21 and extends below the connecting ring 21. The gear frame 23 is fixedly connected to the second connecting frame 22 and is located below the second connecting frame 22. As shown in Figure 7, the gear frame 23 is provided with an upper regulating guide groove 24 and a lower regulating guide groove 27, and the positions of the upper regulating guide groove 24 and the lower regulating guide groove 27 are offset vertically so that they do not interfere with each other. The upper tooth plate 25 is slidably mounted in the upper regulating guide groove 24, one end of the upper spring 26 is fixedly connected to the inner wall of the upper regulating guide groove 24, and the other end of the upper spring 26 is fixedly connected to the upper tooth plate 25. The lower tooth plate 28 is slidably mounted in the lower regulating guide groove 27, one end of the lower spring 29 is fixedly connected to the inner wall of the lower regulating guide groove 27, and the other end of the lower spring 29 is fixedly connected to the lower tooth plate 28. The upper tooth plate 25 and the lower tooth plate 28 are offset vertically so as not to interfere with each other. A total of two clamping rods 210 are provided, and the two clamping rods 210 are fixedly connected to the upper tooth plate 25 and the lower tooth plate 28, respectively. A total of two clamping cases 211 are provided, fixedly connected to the clamping rods 210, and the two clamping cases 211 are provided symmetrically, and the clamping cases 211 preferably have an arc-shaped curved surface structure that fits the outer shape of the mini Chinese cabbage, making it convenient for clamping the mini Chinese cabbage. The transmission member is attached to the gear frame 23 and works in cooperation with the opening / closing control assembly 4 to control the two clamping cases 211 to release the mini Chinese cabbage. The upper spring 26 and the lower spring 29 are both assembled in a biased state, and the biasing force of the upper spring 26 and the lower spring 29 causes the two clamping cases 211 to clamp the mini Chinese cabbage.

[0023] Preferably, as shown in Figures 3 and 4, the connecting ring 21 is fixedly connected to the planetary external gear ring 14 via a gibhead tapered key 217, and the gibhead tapered key 217 is fixedly connected between the connecting ring 21 and the planetary external gear ring 14. As shown in Figure 1, the installation of the gibhead tapered key 217 creates a certain gap between the bottom of the planetary external gear ring 14 and the planetary frame 55, which effectively reduces frictional loss between the planetary external gear ring 14 and the planetary frame 55 during rotation.

[0024] As shown in Figures 4 to 7, the transmission members include an upper gear 213, a lower gear 214, a first speed gear 215, and a second speed gear 216. The upper gear 213 is rotatably mounted on the gear frame 23 and meshes with and connects to the upper tooth plate 25. The lower gear 214 is rotatably mounted on the gear frame 23 and meshes with and connects to both the lower tooth plate 28 and the upper gear 213. As shown in Figure 6, the thickness of the upper gear 213 is greater than the thickness of the lower gear 214. The upper half of the upper gear 213 meshes with and connects to the upper tooth plate 25, and the lower half of the upper gear 213 meshes with and connects to the lower gear 214. The first speed gear 215 is rotatably mounted on the gear frame 23, located on one side of the lower gear 214, and meshes with and connects only to the lower gear 214. The second gear 216 is mounted coaxially with the first gear 215 and is fixedly connected to the central axis of the first gear 215, with a portion extending to the outer circumference of the gear frame 23. When controlling the clamping assembly 2 to release the mini cabbage, the second gear 216 is rotated, causing the second gear 216 to rotate the first gear 215 synchronously, causing the first gear 215 to rotate the lower gear 214, causing the lower gear 214 to rotate the upper gear 213, causing the lower gear 214 to move the lower tooth plate 28, causing the upper gear 213 to move the upper tooth plate 25, and further moving the two clamping cases 211 in a direction away from each other to release the mini cabbage.

[0025] As shown in Figures 1 and 8, the opening / closing control assembly 4 includes a third connecting frame 41, a fixed gear 42, and a moving member. The third connecting frame 41 is fixedly connected to the internal tooth ring 11, and the moving member is attached to the third connecting frame 41. The fixed gear 42 is fixedly connected to the moving member and moves toward the second speed gear 216 when driven by the moving member, and meshes with and connects to the second speed gear 216. The second speed gear 216 rotates due to the force acting on it due to meshing with the fixed gear 42 and the force acting on it due to the revolution of the clamping assembly 2. When the clamping assembly 2 revolves to one side of the opening / closing control assembly 4 while clamping the trimmed mini Chinese cabbage, the moving member is controlled to move the fixed gear 42 toward the second speed gear 216 until the fixed gear 42 meshes with and connects to the second speed gear 216. While the clamping assembly 2 is revolving, the fixed gear 42 rotates the second transmission gear 216, further moving the two clamping cases 211 apart from each other and releasing the mini Chinese cabbage.

[0026] The moving member includes a second motor 43, a drive gear 44, a drive rack 45, and a connecting plate 46. The second motor 43 is fixedly mounted to the third connecting frame 41, and the drive gear 44 is fixedly connected to the output shaft of the second motor 43. The drive rack 45 is slidably mounted to the third connecting frame 41 and is connected in mesh with the drive gear 44. The connecting plate 46 is fixedly connected to the drive rack 45 and is slidably connected to the third connecting frame 41, and the fixed gear 42 is fixedly mounted to the connecting plate 46. As the clamping assembly 2 revolves to one side of the opening / closing control assembly 4 while clamping the trimmed mini Chinese cabbage, the second motor 43 is activated, causing the second motor 43 to rotate the drive gear 44, which moves the drive rack 45, to which the drive gear 44 meshes and connects, toward the clamping assembly 2, and the connecting plate 46 moves the fixed gear 42 toward the clamping assembly 2 until the fixed gear 42 meshes and connects with the second speed gear 216.

[0027] As shown in Figures 1, 9 to 12, the leaf sieving assembly 5 includes support columns 51, a leaf sieving plate 52, connecting rods 53, and a transmission shaft 54. A total of multiple support columns 51 are provided, and the multiple support columns 51 are arranged in an annular array shape. The leaf sieving plate 52 is rotatably mounted on the top of the support columns 51 via ball bearings. One end of the connecting rod 53 is fixedly connected to the outer wall of the leaf sieving plate 52. The transmission shaft 54 ​​is located directly above the leaf sieving plate 52, and the other end of the connecting rod 53 is fixedly connected to the transmission shaft 54. The planetary frame 55 is fixedly connected to the transmission shaft 54. The support columns 51 support the leaf sieving plate 52, the leaf sieving plate 52 supports the transmission shaft 54 ​​via the connecting rods 53, and the transmission shaft 54 ​​supports the planetary frame 55.

[0028] As shown in Figure 12, the leaf sieving plate 52 is formed in a cylindrical shape with an open top, and a first drop-off opening 56 through which separated leaves fall is opened at the center of the bottom plate of the leaf sieving plate 52, and a plurality of second drop-off openings 57 through which roots fall are opened in the bottom plate of the leaf sieving plate 52, and the plurality of second drop-off openings 57 are arranged in an annular array shape around the outer circumference of the first drop-off opening 56. Multiple sets of first contact plates 58 and second contact plates 59 are fixedly connected inside the leaf sieving plate 52, and the first contact plates 58 and second contact plates 59 constitute guide passages that communicate between the inner wall of the leaf sieving plate 52 and the first drop-off opening 56, guiding leaves to collide with the first drop-off opening 56 and fall out. The plurality of guide passages are each located below the corresponding planetary external tooth ring 14. The first contact plates 58 and second contact plates 59 are each constructed by joining multiple arc-shaped plates.

[0029] When the planetary frame 55 rotates, the transmission shaft 54 ​​and connecting rod 53 synchronously rotate the leaf sieving plate 52, causing the trimmed mini Chinese cabbage and roots to fall into the leaf sieving plate 52. When the leaf sieving plate 52 rotates, the smaller volume roots fall from the second drop-off opening 57 into the leaf collection plate 61, and the larger volume leaves fall to the end of the guide passage near the inner wall of the leaf sieving plate 52. Due to the centrifugal force generated as the leaf sieving plate 52 rotates, the mini Chinese cabbage continuously collides with the first contact plate 58 and the second contact plate 59 along the guide passage. In the process of the mini Chinese cabbage colliding with the guide passage, leaves that were not completely separated during the rotation of the clamping assembly 2 can be further separated. The separated leaves then move along the guide passage due to centrifugal force until they fall from the first drop-off opening 56. The fine leaves generated during the sieving process by the leaf sieving disc 52 fall into the leaf collection disc 61 from the second drop-off opening 57 before reaching the first drop-off opening 56. Compared to conventional methods of separating mini Chinese cabbage leaves by cutting and pulling, the present invention is advantageous in that it uses centrifugal force to rotate the mini Chinese cabbage and separate the leaves, thereby avoiding compressive damage to the easily torn leaves of the mini Chinese cabbage and ensuring the integrity of the leaves.

[0030] As shown in Figures 1, 13, and 14, the root cutting assembly 3 includes a mounting plate 31, a root cutting cutter 32, and a regulating ring 33. The mounting plate 31 is fixedly attached to the support frame 12, one end of the root cutting cutter 32 is fixedly connected to the mounting plate 31, the regulating ring 33 is fixedly connected to the other end of the root cutting cutter 32, and the regulating ring 33 is fitted onto the outer circumference of the transmission shaft 54. The installation of the regulating ring 33 restricts the rotation of the transmission shaft 54, improving the stability of the transmission shaft 54 ​​during rotation. As the clamping assembly 2 revolves while clamping the mini Chinese cabbage and passes through the root cutting assembly 3, the root cutting cutter 32 cuts the roots of the mini Chinese cabbage.

[0031] As shown in Figures 1, 14, and 15, the collection and crushing assembly 6 includes a leaf collection plate 61, a crushing bucket 62, a crusher 63, and a support rod 64, the leaf collection plate 61 being located directly below the leaf sieving assembly 5.

The crushing bucket 62 is located on one side of the outlet of the leaf collection plate 61, and the crusher 63 is mounted inside the crushing bucket 62 and is used to crush roots and fine leaves. A drop through hole 65 is opened in the center of the leaf collection plate 61, communicating with a first drop port 56 through which separated leaves fall, and the leaf collection plate 61 is provided with a drop passage 66 that guides roots and fine leaves to fall to the outlet, and the crushing bucket 62 is opened with a supply port that fits the outlet of the leaf collection plate 61. The separated leaves are discharged from the first drop port 56 and the drop through hole 65. In actual applications, the drop-through hole 65 may be equipped with a collection device for collecting leaves, the roots and fine leaves fall through the drop-through passage 66 into the crushing bucket 62, the crusher 63 crushes the roots and fine leaves, and the roots and fine leaves are conveniently processed into feed, fertilizer, etc.

[0032] The planetary gear assembly 1 of the present invention is provided with a total of multiple planetary external tooth rings 14, thereby enabling the simultaneous processing of multiple mini Chinese cabbages. Furthermore, by utilizing the orbital stroke of the planetary gear assembly 1 and the root cutting assembly 3 to perform root cutting on the mini Chinese cabbages, the centrifugal force from the rotation of the planetary gear assembly 1 rotates the root-cut mini Chinese cabbages, separating the leaves and thereby avoiding compressive damage to the fragile leaves. In addition, the present invention can automatically separate the leaves of the mini Chinese cabbages, eliminating the need for extensive manual labor. Moreover, the present invention requires only one first motor 16 as a power source during the process of separating the leaves of the mini Chinese cabbages, allowing for efficient energy saving compared to commercially available modular machines. Furthermore, the large amount of discarded leaves and roots generated by processing the mini Chinese cabbages are all collected, crushed by a leaf crushing device, and conveniently processed into feed, fertilizer, etc., thereby improving resource utilization.
