[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] 1. In this invention, when removing impurities from the round leaves of *Ligustrum lucidum* inside the first screening cylinder, the first screening cylinder is driven to move up and down reciprocally by a movable mechanism to perform screening and impurity removal. This allows the impurities carried on the round leaves of *Ligustrum lucidum* to fall into the second screening cylinder through the first screening hole. In addition, some smaller leaves and broken leaves will also fall into the second screening cylinder. The second screening cylinder can also rotate to screen and remove impurities. After the impurities are discharged, the smaller leaves and broken leaves are left behind. At the same time, the operation of separating broken leaves from whole leaves is completed.

[0020] 2. In this invention, when the first rotating rod is driven to rotate by the drive motor, the first rotating rod controls the rotation of the cam through the drive wheel, the synchronous belt, and the second rotating rod. Moreover, the first rotating rod also controls the rotation of the drive shaft through the drive helical gear, the driven helical gear, and the rotating base. Therefore, with the cooperation of the cam, the protrusion, the baffle, the spring, and the push rod, when the first screening cylinder is controlled to move up and down, the second screening cylinder will also rotate under the drive of the drive shaft, realizing the simultaneous control of the movement of the first screening cylinder and the second screening cylinder, which can quickly remove impurities from the leaves of the mountain jasmine.

[0021] 3. In this invention, the push rod can be reset by the baffle and spring during movement, and the sliding block, limiting groove, sliding channel, moving plate and slide rail can play a guiding and limiting role to ensure the stability of the push rod during multiple reciprocating movements. When the second screening cylinder rotates to screen and remove impurities, it is guided and limited by the limiting rings at the top and bottom, as well as the limiting column and limiting frame, to avoid the second screening cylinder from deviating during rotation, thus ensuring the stability and reliability of the device.

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Example 1

[0034] Reference Figure 1-4 As shown: A pretreatment device for processing round leaves of mountain jasmine includes a base plate 1, a housing 72 fixedly installed on the top of the base plate 1, a processing cylinder 7 fixedly installed on the top of the housing 72, a side plate 2 fixedly installed on one side of the top of the base plate 1, a driving mechanism 4 provided on one side of the side plate 2, a driving motor 3 provided on the other side of the side plate 2, a movable mechanism 5 provided on one side of the side plate 2, and a processing mechanism 6 provided inside the processing cylinder 7.

[0035] The active mechanism 5 includes a fixed plate 52, a cam 51, and a protrusion 542. One side of the fixed plate 52 is fixedly connected to the side plate 2. A push rod 54 is provided on one side of the fixed plate 52. One end of the push rod 54 is fixedly connected to a baffle 56. One side of the baffle 56 is fixedly connected to the protrusion 542. The cam 51 is located on one side of the protrusion 542 and is rotatably mounted on the surface of the fixed plate 52. A limit plate 53 is slidably mounted on the surface of the push rod 54. One side of the limit plate 53 is fixedly connected to the fixed plate 52. A spring 55 is provided between the limit plate 53 and the baffle 56. The spring 55 is sleeved on the surface of the push rod 54, and both ends of the spring 55 are fixedly connected to the limit plate 53 and the baffle 56, respectively.

[0036] The processing mechanism 6 includes a first screening cylinder 64 and a second screening cylinder 68. The first screening cylinder 64 is located inside the second screening cylinder 68. The first screening cylinder 64 has a plurality of first screening holes 641 on its surface and bottom. The second screening cylinder 68 has a plurality of second screening holes 681 on its surface. A connecting frame 63 is fixedly installed on the top of the first screening cylinder 64. Two fixing rods 62 are fixedly connected to one side of the connecting frame 63. The diameter of the first screening hole 641 is larger than the diameter of the second screening hole 681.

[0037] In this embodiment, firstly, when the cam 51 rotates, its convex end on one side can push the protrusion 542 to move. The protrusion 542 can drive the baffle 56 and the push rod 54 connected to it to move together. In addition, during the movement, the baffle 56 will also squeeze the spring 55, causing it to compress and deform. Next, the push rod 54 will control the top mounting plate 61 to move up and down, and the push rod 54 will also slide inside the limit frame 65 to keep the movement trajectory from deviating. Then, when the mounting plate 61 moves, it can drive the fixing rod 62 and the connecting frame 63 to move together, so that the first screening cylinder 64 will also move. By controlling the up and down movement of the first screening cylinder 64, the inner mountain incense round leaves are shaken to separate the leaves from the impurities, so that the impurities fall into the second screening cylinder 68 through the first screening hole 641, achieving the effect of impurity removal. During this movement, some smaller leaves and broken leaves will also fall into the second screening cylinder 68 through the first screening hole 641.

[0038] Finally, while the first screening cylinder 64 is removing impurities from the round leaves of the mountain jasmine, the second screening cylinder 68 will also rotate to remove impurities from the smaller and broken leaves. By using centrifugal force, the impurities are forced to pass through the second screening hole 681 and be thrown out, thereby leaving the smaller and broken leaves and achieving the effect of separating the broken leaves from the whole leaves.

[0039] During the impurity removal process, the leaves can be sprayed with clean water, which can not only clean the leaves, but also shorten the loading, unloading and transfer time, eliminating the need to spray clean water and wet the leaves after they are removed.

[0040] Example 2

[0041] Figure 4-6 As shown, the drive mechanism 4 includes a first rotating rod 41 and a second rotating rod 44. The surface of the second rotating rod 44 is fixedly connected to the cam 51. A drive wheel 42 is fixedly mounted on the surface of the first rotating rod 41, and a driven wheel 45 is fixedly mounted on the surface of the second rotating rod 44. One end of the first rotating rod 41 passes through the housing 72, and a drive helical gear 48 is fixedly mounted on one end of the first rotating rod 41. A driven helical gear 49 meshes with the drive helical gear 48 on one side. A rotating base 46 is rotatably connected to the bottom of the driven helical gear 49. The bottom of the rotating base 46 is fixedly connected to the base plate 1. A drive shaft 47 is fixedly connected to the top of the driven helical gear 49. The top end of the drive shaft 47 passes through the processing cylinder 7, and one end of the drive shaft 47 is fixedly connected to the bottom of the second screening cylinder 68.

[0042] A synchronous belt 43 is fitted on the surface of the drive wheel 42. One side of the synchronous belt 43 is sleeved with the driven wheel 45. One end of the second rotating rod 44 is rotatably connected to the side plate 2. A drive motor 3 is installed on one side of the top of the base plate 1. One end of the first rotating rod 41 passes through the side plate 2. One end of the first rotating rod 41 is fixedly connected to the output end of the drive motor 3.

[0043] In this embodiment, when the drive motor 3 is running, it first drives the first rotating rod 41 to rotate. One end of the first rotating rod 41 is connected to the driving helical gear 48, which rotates along with it. Additionally, the driving wheel 42 mounted on the surface of the first rotating rod 41 also rotates. Then, as the driving wheel 42 rotates, it drives the driven wheel 45 to rotate via the synchronous belt 43. Next, the driving helical gear 48 drives the driven helical gear 49 to rotate, and the driven wheel 45 drives the second rotating rod 44 to rotate. When the driven helical gear 49 rotates on the rotating base 46, it drives the drive shaft 47 to rotate, causing the second screening cylinder 68 connected to the top of the drive shaft 47 to begin rotating and screening out impurities. Furthermore, the cam 51 fixedly sleeved on the surface of the second rotating rod 44 also begins to rotate, simultaneously controlling the up-and-down movement of the first screening cylinder 64 and the rotation of the second screening cylinder 68. This improves the screening and impurity removal effect on the leaves of the mountain jasmine and also allows for the separation of leaves of different sizes.

[0044] Example 3

[0045] according to Figure 4-9 As shown, a sliding groove 21 is provided on the top of the side plate 2, a sliding block 57 is fixedly sleeved on the surface of the push rod 54, a limiting groove 521 is provided on the surface of the fixed plate 52, one end of the sliding block 57 passes through the limiting groove 521 and the sliding groove 21 in sequence, a moving plate 58 is fixedly connected to one end of the sliding block 57, and a mounting plate 61 is fixedly connected to the top of the push rod 54; two slide rails 59 are fixedly installed on one side of the side plate 2, and the moving plate 58 is slidably connected to the slide rails 59; two mounting grooves 611 are provided on the surface of the mounting plate 61, one end of the fixed rod 62 is snapped into the mounting groove 611, and fixing screws 612 are provided on both sides of the mounting plate 61, one end of the fixing screw 612 passes through the mounting plate 61, and the fixing screws... The wire 612 is connected to the fixed rod 62; the top and bottom of the second screening cylinder 68 are fixedly connected to the limiting rings 66, and the inner side of the limiting rings 66 is provided with the limiting post 651. Several limiting frames 65 are fixedly installed on the inner wall of the processing cylinder 7, and the limiting post 651 is located inside the limiting frame 65. The top and bottom of the limiting post 651 are rotatably connected to the limiting frame 65; several reinforcing rods 67 are fixedly installed on the side wall of the second screening cylinder 68, and both ends of the reinforcing rod 67 are fixedly connected to the limiting rings 66; the rotating base 46 is located inside the housing 72, and the bottom side of the processing cylinder 7 is provided with the discharge port 71; the second screening cylinder 68 is located inside the processing cylinder 7, and the inner diameter of the second screening cylinder 68 is larger than the outer diameter of the first screening cylinder 64.

[0046] In this embodiment, firstly, when the cam 51 rotates, it indirectly controls the movement of the protrusion 542 and the push rod 54. When the push rod 54 moves, the sliding block 57 on its surface moves inside the limiting groove 521 and the sliding groove 21. Next, the moving plate 58 slides on the surfaces of the two slide rails 59 to limit the movement of the sliding block 57. Moreover, the limiting groove 521 and the sliding groove 21 also serve as limiting guides for the sliding block 57, preventing the sliding block 57 and the push rod 54 from becoming misaligned during repeated reciprocating movements.

[0047] In addition, during the rotation of the second screening cylinder 68, the top and bottom limiting rings 66 are restricted by multiple limiting posts 651 to ensure stable rotation, preventing the second screening cylinder 68 from shaking or tilting during rotational screening and impurity removal. Moreover, the reinforcement rod 67 can improve the firmness of the connection between the second screening cylinder 68 and the limiting rings 66.

[0048] Finally, after the impurities are removed, when it is necessary to take out the cleaned mountain fern leaves, tighten the fixing screw 612 to contact the positioning of the fixing rod 62, remove the fixing rod 62 from the inside of the mounting groove 611, and then remove the first screening cylinder 64 from the inside of the processing cylinder 7, so as to facilitate the transfer of the mountain fern leaves.

[0049] The usage method and working principle of this device are as follows: First, when the drive motor 3 is running, it will drive the first rotating rod 41 to rotate. One end of the first rotating rod 41 is connected to the active helical gear 48 and rotates together. In addition, the active wheel 42 mounted on the surface of the first rotating rod 41 will also rotate.

[0050] Next, as the drive wheel 42 rotates, it drives the driven wheel 45 to rotate together with the synchronous belt 43. Then, the drive helical gear 48 drives the driven helical gear 49 to rotate, and the driven wheel 45 drives the second rotating rod 44 to rotate. When the driven helical gear 49 rotates on the rotating base 46, it can drive the drive shaft 47 to rotate, causing the second screening cylinder 68 connected to the top of the drive shaft 47 to start rotating. In addition, the cam 51 fixedly sleeved on the surface of the second rotating rod 44 will also start to rotate.

[0051] When cam 51 rotates, its protruding end on one side can push protrusion 542 to move. Protrusion 542 can drive the baffle 56 and push rod 54 connected to it to move together. During the movement, baffle 56 also compresses spring 55, causing it to deform. As the protruding end of cam 51 moves downward, the compressed spring 55 begins to return to its original position, causing protrusion 542 and push rod 54 to move downward. With the rotation of cam 51, protrusion 542 and push rod 54 can begin to reciprocate up and down. Then, push rod 54 controls the up and down movement of the top mounting plate 61.

[0052] Simultaneously, the push rod 54 slides inside the limiting frame 65 to prevent deviation from the movement trajectory. When the push rod 54 moves, the sliding block 57 on its surface moves within the limiting groove 521 and the sliding groove 21. Next, the moving plate 58 slides on the surfaces of the two slide rails 59 to limit the movement of the sliding block 57. The limiting groove 521 and the sliding groove 21 also serve as limiting guides for the sliding block 57, preventing the sliding block 57 and the push rod 54 from tilting during repeated reciprocating movements.

[0053] When the mounting plate 61 moves, it can drive the fixing rod 62 and the connecting frame 63 to move together, so that the first screening cylinder 64 will also move. By controlling the up and down movement of the first screening cylinder 64, the inside of the mountain incense round leaves can be shaken to separate the leaves from the impurities, so that they fall into the second screening cylinder 68 through the first screening hole 641, thus achieving the effect of removing impurities. During this movement, some smaller leaves and broken leaves will also pass through the first screening hole 641 and fall into the second screening cylinder 68.

[0054] Finally, while the first screening cylinder 64 is removing impurities from the round leaves of the mountain jasmine, the second screening cylinder 68 will also rotate under the drive shaft 47. During the rotation of the second screening cylinder 68, the top and bottom limiting rings 66 are restricted by multiple limiting posts 651 to ensure stable rotation and prevent the second screening cylinder 68 from shaking or tilting during rotational screening and impurity removal. The reinforcement rod 67 can improve the firmness of the connection between the second screening cylinder 68 and the limiting rings 66. For smaller and broken leaves, secondary impurity removal is performed. The impurities are thrown out through the second screening hole 681 by centrifugal force, thereby leaving smaller and broken leaves and achieving the effect of separating broken leaves from complete leaves.

[0055] During the impurity removal process, the first screening cylinder 64 moves up and down and the second screening cylinder 68 rotates simultaneously, which can improve the screening and impurity removal effect of the mountain jasmine round leaves. It can also spray clean water on the leaves, which can not only clean the leaves, but also shorten the loading, unloading and transfer time. There is no need to spray clean water and moisten the leaves after taking them out. Then, during the impurity removal process, the impurities and wastewater can be discharged through the discharge port 71.

[0056] Finally, when it is necessary to remove the cleaned mountain fern leaves, tighten the fixing screw 612 to release the positioning of the fixing rod 62, remove the fixing rod 62 from the mounting groove 611, and then remove the first screening cylinder 64 from the processing cylinder 7.

[0057] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
