This ensures precise control of subsequent processes such as fixation, rolling, and fermentation, thereby improving the quality and economic benefits of the finished tea.

[0003] Currently, the sorting of fresh tea leaves mainly relies on the following two methods:

[0004] 1. Fixed mechanical sorting equipment: This type of equipment uses automated equipment such as vibrating screens, air separators, or optical sorting systems to grade fresh leaves through preset parameters. However, this type of equipment is bulky and complex in structure, and needs to be fixedly installed in the processing workshop. Most of them cannot adapt to the scattered and complex terrain environment of tea gardens.

[0005] 2. Manual sorting: Fresh leaves are selected and sorted by workers at the tea-picking site through visual inspection and manual operation. This method is inefficient, relies on the experience and physical labor of skilled workers, has high labor costs, and is difficult to scale up.

[0006] Therefore, there is a need for a tea leaf sorting device that can meet the needs of tea picking sites. Utility Model Content

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0027] Example 1

[0028] To address the technical problems in the background section, the following portable tea leaf sorting device is provided:

[0029] Combination Figures 1-6 As shown, the portable tea leaf sorting device provided by this utility model includes a mounting frame 1. A drive unit 2 is installed on one side of the mounting frame 1, and a sorting unit 4 is installed on the other end of the mounting frame 1. The sorting unit 4 and the mounting frame 1 are connected to each other through a positioning unit 3.

[0030] In the above scheme:

[0031] The mounting bracket 1 enables the assembly and connection between the drive unit 2 and the sorting unit 4. Personnel can perform handheld sorting operations on the sorting unit 4 by operating the drive unit 2. The sorting action does not require personnel to perform, thus achieving handheld automated operation.

[0032] The three sorting layers in sorting unit 4 not only meet the sorting requirements of tea leaves, but also, in conjunction with positioning unit 3, enable the assembly and disassembly of sorting unit 4 and mounting frame 1, allowing personnel to replace the required sorting mesh group according to sorting needs and improve the adaptability of the device.

[0033] The drive unit 2 includes a mounting shell 21, a rotating disk 26 is mounted inside the mounting shell 21, a drive rod 27 is movably mounted on the rotating disk 26, an extended guide frame 28 is mounted inside the mounting shell 21 and is connected to the mounting frame 1, the drive rod 27 is movably connected to the inner side of the guide frame 28, a handle 22 is fixed to the top of the mounting shell 21, and a motor 23 is fixed to the bottom of the mounting shell 21.

[0034] The positioning unit 3 includes an extended plug plate 33 that is mounted on the end of the mounting frame 1. The plug plate 33 is fixedly connected to the sorting unit 4, and a positioning knob 31 for positioning the plug plate 33 is mounted on the mounting frame 1.

[0035] The sorting unit 4 includes a side plate 42. The mounting frame 1 is connected to the side plate 42 via a plug plate 33. A mounting frame 41 is fixedly installed on the inner side of the side plate 42. A sorting mesh plate 43 is fixedly installed inside the mounting frame 41.

[0036] During daily operations:

[0037] Personnel hold handle 22 to lift the mounting shell 21 by hand, then connect the side plate 42 to the mounting frame 1 via the plug plate 33, and then fix it by the positioning knob 31. After completion, personnel can put the tea into the uppermost mounting frame 41 and let it fall onto the sorting screen plate 43. Then, the motor 23 is started by the switch to drive the rotating disk 26 to rotate. At that time, the rotating disk 26 drives the guide frame 28 through the drive rod 27, causing the guide frame 28 to reciprocate within the mounting shell 21. The guide frame 28 then drives the outer mounting frame 1 to move, causing the sorting screen plate 43 within the mounting frame 1 to perform screening operations. The tea leaves are gradually sorted by passing through the three layers of sorting screen plates 43.

[0038] Example 2

[0039] like Figures 1-6 As shown, based on the above embodiments, this embodiment further provides the following:

[0040] In this embodiment, the sorting screen plate 43 is fixedly connected to the inner side of the side plate 42, and the mesh size of the sorting screen plate 43 decreases from top to bottom.

[0041] The sorting screen 43 is fixedly connected to the inside of the side plate 42 and the mounting frame 41. The side plate 42 and the mounting frame 41 form a trough structure to ensure that the tea leaves will remain inside during the sorting process.

[0042] Because the mesh size of the sorting screen 43 decreases from top to bottom, large pieces of tea leaves will remain on the top screen.

[0043] In this embodiment, a rotating shaft 29 is installed inside the mounting shell 21, a rotating disk 26 is fixedly connected to the rotating shaft 29, the output end of the motor 23 is installed and connected to the rotating shaft 29, a connector 210 is fixedly installed on the inner side of the guide frame 28, the connector 210 is movably connected to the end of the drive rod 27, and a module battery 24 is installed on the side of the mounting shell 21.

[0044] During this period, the output end of motor 23 drives the rotating shaft 29 to rotate, which in turn drives the rotating disk 26 to rotate, thus achieving the required driving purpose;

[0045] The guide frame 28 is hinged to the drive rod 27 via the connector 210 to achieve the driving effect;

[0046] The side of the mounting housing 21 is provided with a connector for interfacing with the module battery 24, so as to provide power to the device.

[0048] like Figures 1-6 As shown, based on the above embodiments, this embodiment further provides the following:

[0049] In this embodiment, guide sleeves 25 are fixedly installed on both sides of the mounting shell 21, and an extended guide rod 211 is installed inside the guide sleeve 25. The guide rod 211 is fixedly connected to the mounting bracket 1.

[0050] The guide sleeve 25 and the guide rod 211 work together to achieve the purpose of limiting and guiding;

[0051] During this period, when the guide frame 28 is reciprocating, the guide rod 211 will simultaneously reciprocate within the guide sleeve 25 to ensure stability during the drive.

[0052] Furthermore, the guide sleeve 25 and the guide rod 211 cooperate with each other to support the end mounting bracket 1, ensuring the compactness of the structure.

[0053] In this embodiment, a through discharge port is provided on the side plate 42, and a discharge gate 44 is movably installed at the discharge port.

[0054] During this period, once the tea leaves have been sorted, personnel can open the discharge gate 44 at the discharge port one by one to discharge the remaining tea leaves one by one.

[0055] The discharge gate 44 is connected to the discharge port by a snap-fit ​​mechanism, which facilitates opening and closing operations by personnel.

[0056] In this embodiment, the end of the mounting frame 41 is provided with an insertion interface extending into the interior. The insertion interface is inserted and assembled with the insertion plate 33. The end of the insertion plate 33 is fixedly installed with a fixing block 32 connected to the side plate 42. The insertion plate 33 is provided with a positioning hole 331 that mates with the positioning knob 31.

[0057] During the process of assembling and disassembling the side plate 42 and the mounting bracket 1, the personnel can insert the side plate 42 into the plug-in interface by driving the plug plate 33 through the fixing block 32. After it is fully inserted, the positioning hole 331 will correspond to the inner end of the positioning knob 31. At that time, the personnel can rotate the positioning knob 31. The positioning knob 31 will be threadedly connected with the positioning hole 331 by rotation to complete the fixation.
