The embodiments of this utility model will now be described based on its overall structure.

[0028] like Figures 1-5 As shown, this embodiment provides a tea sorting device, including: Feed hopper 31 is installed at the feed inlet of vibrating frame 3; The vibrating frame 3 is equipped with a feed inlet, a discharge outlet, and multiple layers of detachable screens with different apertures. The multiple layers of screens with different apertures are distributed from high to low within the vibrating frame 3, and the apertures of the multiple layers of screens are distributed from large to small within the vibrating frame 3. Multiple detachable discharge channels 5 are provided at the discharge outlet, and the multiple layers of screens correspond one-to-one with the multiple discharge channels 5. Support frame 1, which is used to support spring assembly 21 pieces 2; The spring assembly 21 is 2, with its bottom end mounted on the support frame 1 and its top end connected to the vibration frame 3. Specifically, the support frame 1 has four columns 11, and the spring assembly 21 includes four spring assemblies 21. The bottom ends of the four spring assemblies 21 are respectively mounted on the four columns 11, and the top ends of the four spring assemblies 21 are respectively connected to the four corners of the bottom plate of the vibration frame 3. The top ends of two spring assemblies 21 located on the same side are connected to the bottom plate of the vibration frame 3 through structural steel to increase the contact area.

[0029] Vibration motor 4 is installed at the bottom of vibration frame 3. Vibration motor 4 is an existing product used in vibrating screens and will not be described in detail here.

[0030] Multiple clamping components are provided on the inner side wall of the vibrating frame 3 near the feed inlet. The multiple clamping components are distributed in the vibrating frame 3 from high to low. Each clamping component includes at least two clamping parts 6, which are spaced apart on the same horizontal plane. All clamping parts 6 of each clamping component are used to clamp one end of the screen.

[0031] The clamping component 6 includes a first clamping plate and a second clamping plate, which are symmetrically distributed at the top and bottom of the screen. Both the first and second clamping plates are connected to the vibrating frame 3 by a first bolt 63 and a first nut 64. The first and second clamping plates clamp the screen by a second bolt 65 and a second nut 66. This arrangement facilitates assembly and disassembly, making it suitable for different tea grading processes.

[0032] The first and second clamping plates have the same structure, each including a vertical plate 61 and a horizontal plate 62. The vertical plate 61 has a first bolt 63 hole, and the horizontal plate 62 has a second bolt 65 hole. The first bolt 63 passes through the first bolt 63 hole of the first clamping plate and the inner wall of the vibration box in sequence, and is threadedly connected to the first nut 64. The second bolt 65 passes through the second bolt 65 hole of the first clamping plate, the screen, and the second bolt 65 hole of the second clamping plate in sequence, and is threadedly connected to the second nut 66. This arrangement facilitates assembly and disassembly.

[0033] Multiple connecting rods 7 are provided on the inner wall of the vibrating frame 3 near the discharge port. These connecting rods 7 are distributed sequentially from high to low within the vibrating frame 3, and are arranged at an angle, sloping from the upper outer surface to the lower inner surface. The other ends of the multi-layer screens are connected to the connecting rods 7, and the multiple discharge channels 5 are also connected to the connecting rods 7. This arrangement of the connecting rods 7 ensures that the discharge channels 5 do not interfere with each other, facilitates the connection between the screens and the connecting rods 7, and allows some of the screens to extend into the discharge channels 5, ensuring that the tea leaves of the appropriate grade are accurately fed into the discharge channels 5. It should be noted that the connection method between the connecting rods 7 and the side plate of the vibrating frame 3 can be achieved by creating corresponding holes in the side plate, through which the connecting rods 7 pass, and by setting corresponding locking pins on the outside of the vibrating frame 3 to prevent the connecting rods 7 from disengaging. Ideally, locking pins should be installed on both sides of the connecting rods 7 on the side plate for locking.

[0034] Each discharge channel 5 has multiple hooks 8 at its top, spaced apart, and each hook 8 is engaged with a corresponding connecting rod 7. Adjacent discharge channels 5 abut against each other on their sides. This arrangement ensures that the sidewall of the discharge channel 5 closest to the bottom plate of the vibrating frame 3 abuts against the bottom plate, and the sequentially arranged discharge channels 5 abut against each other, improving stability. Considering that some tea leaves may have fewer grades, and some discharge channels 5 may not abut against each other, while the vibrating frame 3 is vibrating due to the vibration motor 4, potentially causing the discharge channel 5 to detach from the connecting rod 7, a slot is provided on the connecting rod 7. The hooks 8 are inserted into the slots to complete the engagement, thus limiting the swing of the discharge channel 5 relative to the connecting rod 7. A limiting pin 9 hole is also provided on the connecting rod 7, and an insertion hole is provided on the hook 8. The limiting pin 9 passes through the limiting pin 9 hole and the insertion hole sequentially, restricting the vertical movement of the discharge channel 5 and ensuring that the discharge channel 5 will not detach from the connecting rod 7.

[0035] The width of each discharge channel 5 gradually decreases at the end furthest from the connecting rod 7. By setting the discharge channels 5 in this way, tea leaves of corresponding grades are collected and transported to the corresponding grading containers.

[0036] The top of the vibration frame 3 is an openable cover plate 32. Specifically, the cover plate 32 is fastened to the end plate of the vibration frame 3 by a snap fastener, and the cover plate 32 is connected to the side plate of the vibration frame 3 by a hinge. This design makes it convenient for staff to observe the inside of the vibration frame 3.

[0037] One side of the vibrating frame 3 is an openable side plate 33. Specifically, the side plate 33 is connected to the bottom plate of the vibrating frame 3 via a hinge, and the side plate 33 is fastened to the end plate of the vibrating frame 3 via a snap fastener. This design facilitates the replacement of the screen, the discharge channel 5, and the cleaning of the vibrating frame 3.

[0038] It should be noted that the cover plate 32 is located near a hopper inlet, which is connected to the feed inlet. The hopper inlet is equipped with a hopper, which makes it convenient for workers to pour tea leaves into the hopper.

[0039] It should be noted that the screen can be connected to the connecting rod by binding.

These descriptions are not intended to limit the present invention to the precise forms disclosed, and it is obvious that many changes and variations can be made based on the above teachings. Although embodiments of the present invention have been shown and described, these specific embodiments are merely explanations of the present invention and are not intended to limit the invention.
