Description

Technical Field

[0001] The utility model relates to the technical field of sorting devices, in particular to a novel sorting device. Background Art

[0002] Tea is a drinkable beverage made from the tender buds, leaves, or shoots of the tea plant. Depending on the processing method, tea can be categorized as green tea, black tea, oolong tea, white tea, yellow tea, and dark tea. Tea must be processed before it can be used. Tea processing refers to the process of transforming fresh tea leaves into finished tea with a specific flavor, aroma, and quality. The main reasons for this include improving flavor and aroma, and enhancing tea quality. Processing helps tea maintain its appearance, color, and texture, and enhances its shelf life, allowing it to be stored for long periods without deterioration, maintaining and enhancing its health benefits, and facilitating storage and transportation. Sorting is a crucial step in tea processing, screening the tea leaves to ensure the quality of the finished tea. Sorting removes tea leaves of varying sizes, shapes, and colors, ensuring a more consistent appearance and quality, meeting market demand. Tea leaves may be contaminated with impurities such as old leaves, stems, debris, or other non-tea materials during picking and primary processing. Sorting effectively removes these impurities, improving the purity and quality of the tea. After sorting, tea leaves are more uniform in size, receiving even heat during brewing, contributing to a more consistent flavor and taste. Different grades of tea require different processing methods and times. After sorting, tea leaves can be categorized and processed based on their quality and size, resulting in different grades of tea to meet the needs of different consumers. Therefore, sorting is a key step in ensuring tea processing quality, enhancing the appearance, taste, and market competitiveness of the finished tea.

[0003] Existing tea processing and sorting equipment typically relies on multiple power units working in concert to complete the sorting process. While this multi-powered design can improve sorting accuracy and automation to a certain extent, it also presents some significant drawbacks. First, the simultaneous operation of multiple power units leads to increased energy consumption, which in turn increases production costs. Furthermore, the complexity and diversity of the equipment increases the difficulty of operation and maintenance, making it prone to failures and affecting the continuity and stability of sorting. More importantly, even with a large investment of energy, sorting efficiency may not necessarily improve significantly. Coordination issues between equipment and technical bottlenecks can lead to suboptimal sorting speeds, making it difficult to meet the efficiency requirements of large-scale production.

[0004] Therefore, those skilled in the art provide a novel sorting device to solve the problems raised in the above background technology. Utility Model Content

[0005] The purpose of the utility model is to solve the shortcomings of the prior art and to propose a new type of sorting device. The device is more energy-saving and has high sorting efficiency.

[0006] To achieve the above-mentioned object, the present invention provides the following technical solution: a novel sorting device, comprising a sorting housing, a driving mechanism and a sorting mechanism, wherein three annular holes are opened inside the sorting housing, and reinforcement rods are fixedly provided on both sides of the lower end of the interior;

[0007] The driving mechanism includes an output motor and an air collecting chamber, a pinion is fixedly provided at the uppermost end of the output end of the output motor, a rotating shaft is rotatably provided at the center of the upper end surface of the air collecting chamber through a bearing, a wind wheel is fixedly provided at the lower end of the rotating shaft, and pulleys are fixedly provided at the middle of the output end of the output motor and the upper end of the rotating shaft, and a transmission belt is connected between the two pulleys;

[0008] The sorting mechanism includes a support tube, and filter discs are fixedly sleeved at the upper end, middle part and lower end of the support tube. A positioning bearing is fixedly sleeved at the lower end of the support tube. A large gear is fixedly sleeved on the support tube body between the positioning bearing and the lowermost filter disc. Two groups of one-way exhaust holes are opened on the support tube body, and sliders are fixedly set at both ends of the three filter discs.

[0009] Furthermore, the lower end surface of the sorting shell is triangular and fixed with three supporting legs, and the lower end surface of the sorting shell is provided with a plurality of dust collection holes.

[0010] Furthermore, three discharge pipes are fixedly provided on one side of the sorting shell, and the three discharge pipes correspond one to one with the three filter plates. The opposite ends of the two reinforcement rods are fixedly connected to the outer surface of the positioning bearing, and the slider is slidably provided inside the annular hole.

[0011] Furthermore, the wind wheel is located inside the air collecting chamber, the pulley on the rotating shaft is located at the upper part of the air collecting chamber, an air duct is connected between the lower end of one side of the air collecting chamber and the lower end of the support tube, and a plurality of one-way air inlet holes are provided on the upper end surface of the air collecting chamber.

[0012] Furthermore, the lower ends of the output motor and the air collecting chamber are fixedly arranged on the inner bottom surface of the sorting shell, and the small gear is meshed with the large gear.

[0013] Furthermore, the two groups of one-way exhaust holes are respectively located at the upper end of the lowest filter disc and the upper end of the middle filter disc, and the three filter discs are respectively connected to large-pore filtration, medium-pore filtration and fine-pore filtration from top to bottom.

[0014] The utility model has the following beneficial effects:

[0015] The utility model proposes a new type of sorting device. The wind blowing and stirring function of the device drives the wind wheel to rotate through the motor. The airflow generated by the rotation of the wind wheel is guided to the surface of the filter disk through the air duct inside the device to blow and stir the tea leaves. This stirring method avoids direct contact between mechanical parts and the tea leaves, so that the tea leaves can be evenly dispersed and disrupted, but will not damage the texture of the tea leaves. Traditional sorting devices sometimes produce pressure or excessive friction on the tea leaves due to the use of multi-power equipment, which may cause the tea leaves to break or be damaged in shape. The wind blowing and stirring of the device effectively avoids this problem. Secondly, the rotary stirring function drives the small gear to rotate through the motor, and then drives the large gear to rotate slowly. In conjunction with the rotation of the filter disk, the tea leaves are stirred and screened under the dual effects of wind and rotation, and the tea leaves are gradually separated on the filter disks with different apertures. Layer filtration is used to achieve sorting. This rotary stirring not only improves the uniformity of tea stirring, but also ensures that the tea can be gradually separated, improving the accuracy and efficiency of screening. More importantly, when the device is working, whether it is wind stirring or rotary stirring, neither will come into direct contact with the tea. This design fundamentally avoids the physical damage that mechanical operation may cause to the tea. The tea will not be squeezed or excessively rubbed during the sorting process, thereby maintaining its natural shape and quality, and ultimately improving the overall quality of the finished tea. In addition, since the device only requires one motor to complete all stirring and sorting operations, it greatly reduces energy consumption and is more energy-efficient than traditional sorting devices that require multiple motors. At the same time, the simplified structure makes the operation and maintenance of the equipment more convenient, reducing complexity and operating costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] Reference Figure 1 、 Figure 2 、 Figure 3 The utility model provides an embodiment: a new type of sorting device, including a sorting shell 1, a driving mechanism 2 and a sorting mechanism 3. Three annular holes 7 are opened inside the sorting shell 1, and reinforcement rods 4 are fixed on both sides of the lower end.

[0028] The lower end surface of the sorting housing 1 is in a triangular shape and is fixedly provided with three supporting legs 6 . The lower end surface of the sorting housing 1 is provided with a plurality of dust collection holes 5 .

[0029] Specifically, an annular hole 7 within the sorting housing 1 provides guidance and positioning for the internal sliding assembly slider 302, ensuring smooth movement and precise operation of all components. The design of the reinforcement rod 4 enhances the stability of the overall structure and serves to secure the sorting mechanism 3. The triangular support legs 6 provide a solid foundation, keeping the device stable during operation and preventing tilting or shaking. The dust collection holes 5 at the bottom of the housing promptly discharge dust and impurities generated during the sorting process, preventing them from accumulating inside the device, ensuring clean operation and the purity of the tea leaves sorted.

[0030] Reference Figure 7 、 Figure 8The driving mechanism 2 includes an output motor 207 and an air collecting chamber 201. A small gear 205 is fixedly provided at the upper end of the output end of the output motor 207. A rotating shaft 203 is rotatably provided at the center of the upper end surface of the air collecting chamber 201 through a bearing. A wind wheel 209 is fixedly provided at the lower end of the rotating shaft 203. A pulley 206 is fixedly provided at the middle part of the output end of the output motor 207 and the upper end of the rotating shaft 203. A transmission belt 204 is connected between the two pulleys 206.

[0031] The wind wheel 209 is located inside the air collecting chamber 201, the pulley 206 on the shaft 203 is located at the upper part of the air collecting chamber 201, and an air duct 208 is connected between the lower end of one side of the air collecting chamber 201 and the lower end of the support tube 301. A plurality of one-way air inlet holes 202 are provided on the upper end surface of the air collecting chamber 201.

[0032] Specifically, the drive mechanism 2 is the device's core power source. The output motor 207 drives the device's multiple functions via a pulley 206 and a transmission belt 204. The impeller 209 generates a strong airflow via the rotating shaft 203, dispersing and stirring the tea leaves, effectively preventing them from excessive friction or damage during the sorting process. This design not only improves stirring and sorting efficiency but also ensures stable airflow direction through the one-way air inlet 202, preventing backflow. This design enables the drive mechanism 2 to achieve multiple stirring functions with minimal energy consumption, resulting in energy-saving and high-efficiency results.

[0033] Reference Figure 4 、 Figure 5 、 Figure 6 The sorting mechanism 3 includes a support tube 301. Filter discs 303 are fixedly sleeved at the upper end, middle part and lower end of the support tube 301. A positioning bearing 305 is fixedly sleeved at the lower end of the support tube 301. A large gear 304 is fixedly sleeved on the support tube 301 between the positioning bearing 305 and the lowermost filter disc 303. Two groups of one-way exhaust holes 306 are opened on the support tube 301. Sliders 302 are fixedly set at both ends of the three filter discs 303.

[0034] The lower ends of the output motor 207 and the air collecting chamber 201 are fixedly arranged on the inner bottom surface of the sorting shell 1, and the small gear 205 and the large gear 304 are meshed and connected.

[0035] Specifically, the sorting mechanism 3 utilizes the rotation of filter discs 303 and large gears 304 to grade and screen the tea leaves. Multiple filter discs 303 screen tea particles of varying sizes layer by layer from top to bottom. Through wind power and the rotating agitation driven by the gears, the tea leaves are thoroughly dispersed and agitated on the filter discs 303, achieving an efficient sorting process. The slow rotation of the large gears 304 ensures the stability of the sorting process, preventing damage to the tea leaves that could occur due to high-speed agitation. One-way exhaust holes 306 further enhance the sorting and agitation efficiency through precise airflow.

[0036] Reference Figures 1-8 Three discharge pipes 8 are fixedly mounted on one side of the sorting housing 1, corresponding one to each of the three filter discs 303. Opposite ends of two reinforcement rods 4 are fixedly connected to the outer surface of a positioning bearing 305. A slider 302 is slidably mounted within the annular hole 7. Two sets of one-way exhaust holes 306 are located at the upper end of the lowest and middle filter discs 303, respectively. From top to bottom, the three filter discs 303 correspond to large-pore filtration, medium-pore filtration, and fine-pore filtration, respectively.

[0037] Specifically, the discharge pipe 8 closely cooperates with the filter discs 303 to ensure that tea leaves of different sizes and grades are sorted and discharged separately, achieving automated grading. This multi-outlet design simplifies the collection process of sorted tea leaves, reduces manual intervention, and improves production efficiency. Furthermore, the multi-layered filtration system of the three filter discs 303 ensures precise screening of the tea leaves. Each filter disc 303 has a different pore size, capable of processing large, medium, and fine tea leaves respectively, ensuring tea quality and accurate grading.

[0038] Working principle: When in use, tea leaves carrying dust are poured into the upper part of the sorting housing 1 and fall onto the uppermost filter disc 303. The upper part of the sorting housing 1 is then covered with a lid, and the output motor 207 is started. The output end of the output motor 207 rotates to drive the pinion 205 to rotate, and at the same time, the rotating shaft 203 is driven to rotate by the transmission belt 204. The rotation of the rotating shaft 203 drives the wind wheel 209 to rotate. After the wind wheel 209 rotates, air enters the air collecting chamber 201 through the upper one-way air inlet 202, and then enters the interior of the support tube 301 through the guidance of the air duct 208, and finally is discharged from the one-way exhaust hole 306, blowing the tea leaves on the filter disc 303 and disrupting the tea leaves.

[0039] Secondly, when the small gear 205 rotates quickly, it drives the large gear 304 to rotate slowly. The rotation of the large gear 304 drives the filter plate 303 to rotate. The tea leaves are blown by the wind and rotated, which improves the stirring efficiency. At the same time, it will not cause squeezing of the tea leaves, avoids damage to the tea leaves, and improves the quality of tea production. In this process, the tea leaves will be filtered layer by layer through different filter holes on the filter plate 303 to achieve the effect of sorting. Different tea leaves are guided out by different discharge pipes 8, and the final dust falls through the dust collection hole 5.

[0040] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
