[0041] Example

[0042] Please refer to Figure 1-7 As shown, this embodiment provides a rotary sorting device, including a sorting body 1, which is provided with a sorting channel 11 connected from top to bottom. A sorting wheel 2 is rotatably provided in the middle of the sorting channel 11, and the thickness of the sorting wheel 2 is equal to the middle width of the sorting channel 11, and the diameter of the sorting wheel 2 is smaller than the middle length of the sorting channel 11. Sorting slots 21 are provided at both ends of the diameter of the sorting wheel 2. In this embodiment, the number of sorting slots 21 is two, that is, the sorting wheel 2 rotates 180° to complete a sorting action. Similarly, the number of sorting slots 21 can also be one, three, four or more. A corrugated section 22 is provided on the circumference of the sorting wheel 2, and the corrugated section 22 is located on both sides of the sorting slot 21. Please refer to Figure 2 As shown, a downward-sloping guide plate is fixed within the sorting channel 11, positioned above the sorting wheel 2. The free end of the guide plate extends to the side of the sorting wheel 2. The guide plate, the top of the sorting wheel 2, and the sorting body 1 enclose a stacking area 14, while the bottom of the guide plate, the sorting wheel 2, and the sorting body 1 enclose a discharge area 15. A drive mechanism 4 is fixed within the sorting body 1. The drive end of the drive mechanism 4 is in driving connection with the sorting wheel 2, driving the sorting wheel 2 to rotate and perform sorting. Materials enter the stacking area 14 within the sorting channel 11 from above and are accumulated there, awaiting sorting and discharge. Single materials fall under the influence of gravity into the sorting slot 21 of the sorting wheel 2, and as the sorting wheel 2 rotates, they are transported to the discharge area 15. The remaining materials, due to the size of the sorting slot 21 and the obstruction of the guide plate end, remain in the stacking area 14 awaiting the next sorting. The sorting slot 21 opens downward during rotation, feeding the materials into the lower opening of the sorting channel 11 to complete the sorting process. This process does not generate significant impact on the materials, and the materials fall a short distance during the sorting process, effectively preventing damage to the materials during the sorting process. The thickness of the sorting wheel 2 is equal to the width of the middle portion of the sorting channel 11, and the diameter of the sorting wheel 2 is less than the length of the middle portion of the sorting channel 11. The dimensions of the corresponding positions of the sorting wheel 2 and the sorting body 1 are controlled to prevent materials from leaking from the sides of the sorting wheel 2, thereby affecting the normal sorting process of the sorting wheel 2. At the same time, in addition to the sorting groove 21 for sorting, the circumferential side of the sorting wheel 2 is also provided with a corrugated section 22. Compared with the flat surface, the corrugated section 22 can apply a greater thrust to the material, and can synchronously push the material on the upper part of the sorting wheel 2 during the sorting process, effectively avoiding the material from being blocked on the upper part of the sorting wheel 2 and affecting the sorting process.

[0043] Please refer to Figure 2 and Figure 3As shown, in this embodiment, there are two guide plates, namely a left guide plate 122 and a right guide plate 121. The left guide plate 122 and the right guide plate 121 are respectively located on the left and right sides above the sorting wheel 2. The left guide plate 122 and the right guide plate 121 are arranged in a funnel shape above the sorting wheel 2 to control the movement of materials toward the sorting wheel 2 and guide the materials. Specifically, the right guide wheel is located below the left guide wheel, effectively increasing the size of the upper stacking area 14 to accommodate more materials. In this embodiment, the free end of the left guide plate 122 is spaced apart from the sorting wheel 2. A pusher wheel 3 is rotatably arranged in the sorting channel 11. The pusher wheel 3 is located between the free end of the seat guide plate and the sorting wheel 2. The driving end of the drive mechanism 4 is connected to the pusher wheel 3, driving the pusher wheel 3 and the sorting wheel 2 to rotate synchronously. During the sorting process, the pusher wheel 3 pushes the materials, further preventing the materials from getting stuck above the sorting wheel 2 and affecting the stable progress of the sorting process.

[0044] Please refer to Figure 7 As shown, in this embodiment, the pusher wheel 3 includes a wheel body 31, to which are fixed multiple pusher groups 32. The multiple pusher groups 32 are fixed at intervals around the wheel body 31. The pusher groups 32 include multiple pusher rods 321 arranged in a row. The multiple pusher rods 321 are spaced apart from each other, which reduces the weight of the pusher wheel 3 while meeting the requirements of pushing different materials, thereby reducing energy loss and reducing costs.

[0045] Specifically, the sorting body 1 includes a base 13 and a sorting cylinder 12, and the sorting cylinder 12 is fixed on the top surface of the base 13. The driving mechanism 4 is fixed in the base 13, and the sorting wheel 2, the pushing wheel 3, the left guide plate 122 and the right guide plate 121 are all arranged in the sorting cylinder 12. Figure 5 As shown, the top surface of the base 13 is provided with an inwardly recessed clearance groove 131. The bottom surface of one side of the clearance groove 131 is a circular arc surface 1311. The bottom end of the sorting wheel 2 extends into the clearance groove 131 and is located above the circular arc surface 1311. The bottom surface of the other side of the clearance groove 131 is provided with a discharge channel 1312, which is connected to the sorting barrel 12 to form the sorting channel 11. The clearance groove 131 makes way for the sorting wheel 2, reducing the overall height of the rotary sorting device and fully utilizing the internal space. The discharge channel 1312 is located on the side of the circular arc surface 1311 and extends in a vertical direction. The discharge channel 1312 is located tangentially to the sorting wheel 2. During the sorting process, the material is ensured to accurately fall into the discharge channel 1312 to complete the sorting and discharge.

[0046] Please refer to Figure 4As shown, in this embodiment, the drive mechanism 4 includes a drive motor 41, the drive end of which is connected to a drive gear 42. A first transmission gear 43 is rotatably provided within the base 13 and meshes with the drive gear 42. A drive channel 1313 is provided on the top surface of the base 13, and the top of the first transmission gear 43 extends outward through the drive channel 1313. The drive ends of the sorting wheel 2 and the pusher wheel 3 pass through the sorting barrel 12 and are respectively provided with a sorting gear 23 and a pusher gear 33. The sorting gear 23, the pusher gear 33, and the first transmission gear 43 mesh with each other. In this embodiment, the first transmission gear 43 is located on the side of the clearance groove 131, fully utilizing the width of the base 13 and achieving high space utilization of the base 13. The drive motor 41 drives the drive gear 42 to rotate, thereby driving the first transmission gear 43, the sorting gear 23, and the pusher gear 33 to rotate synchronously. In this embodiment, a second transmission gear 124 is provided on the outer rotational side of the sorting drum 12. The second transmission gear 124 is positioned between the sorting gear 23 and the pusher gear 33, and the second transmission gear 124, the sorting gear 23, and the pusher gear 33 mesh with each other. The second transmission gear 124, which serves as a transmission component for the sorting gear 23 and the pusher gear 33, reduces the size and number of teeth of the sorting gear 23 and the pusher gear 33, while ensuring that the drive gear 42, the first transmission gear 43, the sorting gear 23, the second transmission gear 124, and the pusher gear 33 rotate more synchronously. This results in the drive gear 42 and the first transmission gear 43 being larger than the sorting gear 23 and the pusher gear 33, resulting in a larger transmission ratio and a higher rotation rate for the sorting wheel 2 and the pusher wheel 3, thereby improving sorting efficiency. In this embodiment, the driving gear 42 and the first transmission gear 43 are rotatably connected to the base 13 via a rotating shaft, and the sorting gear 23, the second transmission gear 124 and the pusher gear 33 are rotatably connected to the sorting cylinder 12 via a rotating shaft.

[0047] Please refer to Figure 1 and Figure 4 As shown, in this embodiment, outwardly extending protrusions 125 are provided on both sides of the top width of the sorting drum 12. The protrusions 125 effectively increase the space at the top of the sorting drum 12, accommodating more material. Furthermore, the protrusions 125 are located above the drive gear 42, the first transmission gear 43, the sorting gear 23, the second transmission gear 124, and the pusher gear 33, vertically blocking these gears. This prevents material from falling onto these gears, which could affect transmission between them.

[0048] Please refer to Figure 1-4As shown, in this embodiment, a cover plate 123 is hingedly connected to the top opening of the sorting cylinder 12. The cover plate 123 seals or opens the top opening of the sorting cylinder 12. The cover plate 123 protects the sorting channel 11, preventing debris from entering the sorting channel 11 when not in use and affecting the rotation of the sorting wheel 2.

[0049] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included in the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
