[0002] Vibrating sieves are key equipment in tea processing for grading tea leaves and improving product consistency and quality. These devices effectively separate tea leaves of different particle sizes, shapes, and weights through vibration or rotation combined with a multi-layered screen structure. They are widely used in the processing of green tea, black tea, oolong tea, and substitute teas (such as rosemary tea).
[0003] Most existing tea processing vibrating screen devices consist of a relatively enclosed box with a feed pipe and a discharge pipe. This enclosed box makes it difficult to disassemble and wash the internal screen, which can easily cause cross-contamination of flavors when screening different varieties of tea, thus reducing the quality of the tea and the practicality of the device. Utility Model Content
[0004] The technical problem to be solved by this utility model is to provide a tea vibrating screen device with a layered discharge mechanism. The device is equipped with a rinsing component, which can rinse the inside of the vibrating box to prevent the tea from mixing flavors.
[0005] To solve the above problems, this utility model provides the following technical solution: a tea vibrating sieve device with a layered discharge mechanism, comprising a support foot and a vibrating box mounted on the support foot. The vibrating box contains a primary screen and a secondary screen arranged vertically, the aperture of the primary screen being larger than that of the secondary screen. The top of the vibrating box has a feed inlet, the bottom has a bottom discharge outlet, and the sides of the vibrating box have upper and lower discharge outlets for discharging from the primary and secondary screens, respectively. The device also includes a vibrating motor and a rinsing assembly. The rinsing assembly includes two chutes, a motor, a lead screw, a water supply pipe, a suction pipe, a water pump, a water collection column, and multiple nozzles installed at the lower end of the water collection column and connected to it. The top of the vibrating box has a feed inlet for discharging from the primary screen and the secondary screen. A rectangular through-hole allows the water pipe to move. Two sliding grooves are installed on the inner wall of the top of the vibrating box. A lead screw is movably installed in one of the sliding grooves and connected to a motor. The motor is installed on the outer wall of the vibrating box. A nut is installed on the lead screw, and the nut is connected to one end of the water collection column via a sliding plate. A slider is movably installed in the other sliding groove and connected to the other end of the water collection column. The water supply pipe passes through the rectangular through-hole at the top of the vibrating box. The lower end of the water supply pipe is connected to the water collection column, and the upper end is connected to the suction pipe via a flexible hose. A suction pump is installed on the suction pipe. At least four support blocks are respectively set below the primary screen and the secondary screen. Support springs are installed on the support blocks, and the upper ends of the support springs are connected to the primary / secondary screens. The oscillating motor is installed at the bottom of the vibrating box.
[0006] Furthermore, the primary and secondary screens are inclined, with the end of the primary / secondary screen closest to the upper / lower discharge port being the lower end and the other end being the higher end.
[0007] Furthermore, the vibration box is mounted on the support feet via shock-absorbing springs.
[0008] Furthermore, the vibrating box below the secondary screen is equipped with a rectangular conical discharge channel with a larger top and smaller bottom and a rectangular cross-section. The lower end of the rectangular conical discharge channel is connected to the bottom discharge port.
[0009] Furthermore, a rubber sealing cover is provided inside the rectangular through hole of the vibration box.
[0010] Furthermore, it also includes a water collection tank, into which the water suction pipe extends.
[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model, by incorporating a rinsing assembly, enables the rinsing of the vibrating chamber as needed. Specifically, a water pump is activated to draw water from a collection tank or other water container through a suction pipe. Water then flows through a delivery pipe into the water collection column and is sprayed out through nozzles. Simultaneously, a motor is activated, causing its output end to rotate a lead screw. This rotation, in turn, causes a nut to move a sliding plate along the lead screw, which in turn moves the water collection column, rinsing the primary and secondary screens to prevent cross-contamination of tea flavors, improve tea quality, and enhance the practicality of the screening device. Furthermore, when there are significant amounts of residual impurities inside the vibrating chamber, the rinsing assembly can also be used to clean the interior.
[0012] 2. This utility model uses a support block and a support spring to install the primary and secondary screens in the vibration box, and an oscillating motor is installed at the bottom of the vibration box. When working, the oscillating motor drives the vibration box to vibrate, the vibration box drives the support block to vibrate, and the support block then transmits the vibration to the primary and secondary screens through the support spring. This method of transmitting vibration through the spring makes the vibration effect of the screen better and the sieving and grading of tea more accurate. Attached Figure Description

[0020] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.
[0021] Example 1: A tea leaf vibrating sieve device with a layered discharge mechanism, please refer to [link / reference]. Figures 1-4 The system includes a support foot 1 and a vibrating box 2 mounted on the support foot. The vibrating box 2 contains a primary screen 10 and a secondary screen 9 arranged vertically, with the secondary screen 9 located below the primary screen 10. The aperture of the primary screen 10 is larger than that of the secondary screen 9. A feed inlet 3 is located at the top of the vibrating box 2, through which tea leaves enter and fall onto the primary screen 10. A bottom discharge outlet 14 is located at the bottom of the vibrating box 2, and an upper discharge outlet 5 and a lower discharge outlet 6 are located on the sides of the vibrating box for discharging tea leaves from the primary screen 10 and the secondary screen 9, respectively. The primary and secondary screens are inclined, with the end of the primary / secondary screen closest to the upper / lower discharge outlet being the lower end and the other end being the higher end. The lower end of the primary screen 10 is connected to the upper discharge port 5 through the upper guide plate 16. Tea leaves that do not pass through the primary screen are discharged from the upper discharge port 5, while tea leaves that pass through the primary screen 10 fall onto the secondary screen 9. The lower end of the secondary screen 9 is connected to the lower discharge port 6 through the lower guide plate 15. Tea leaves that do not pass through the secondary screen 9 are discharged from the lower discharge port 6, while tea leaves that pass through the secondary screen 9 are discharged from the bottom discharge port 14.
[0022] The device also includes a vibrating motor 8 and a rinsing assembly 4. The rinsing assembly includes two sliding grooves 46, a motor 41, a lead screw 410, a water supply pipe 42, a water pump 45, a water suction pipe 44, a water collection column 48, and multiple nozzles 47 installed at the lower end of the water collection column 48 and connected to the water collection column. The top of the vibrating box 2 has a rectangular through hole 21 for the water supply pipe to move. The two sliding grooves 46 are installed on the inner wall of the top of the vibrating box 2. The lead screw 410 is movably installed in one of the sliding grooves 46 through a bearing. The lead screw 410 is connected to the motor 41, and the motor 41 is installed in the vibrating box 2. On the outer wall, a nut is installed on the lead screw 410. The nut is connected to one end of the water collection column 48 via a slide plate 49. When the lead screw rotates, the nut moves linearly on the lead screw 410, thereby driving the slide plate 49 to move within the slide groove 46. A slider 411 is movably installed in another slide groove. The slider 411 can move within the slide groove and is connected to the other end of the water collection column 48. The slider 411 is equivalent to a driven part. When the nut drives the water collection column 48 to move via the slide plate 49, the slider 411 moves synchronously, making the movement of the water collection column 48 smoother. The water supply pipe 42 passes through the rectangular through hole 21 at the top of the vibration box. The lower end of the water supply pipe is connected to the water collection column 48, and the upper end is connected to the suction pipe 44 via a flexible hose 43. When the water collection column 48 moves, the water supply pipe 42 moves within the rectangular through hole 21. The suction pump 45 is installed on the suction pipe 44. Support blocks 11 are respectively installed at the four corners below the primary screen 10 and the secondary screen 9, that is, four support blocks are respectively installed below the primary screen 10 and the secondary screen 9. Support springs 12 are installed on the support blocks 11, and the upper ends of the four support springs 12 are connected to the four corners of the primary / secondary screen. There are gaps between the primary and secondary screens and the inner wall of the vibration box, and the primary and secondary screens do not contact the vibration box. The oscillation motor 8 is installed at the bottom of the vibration box 2, and the operation of the oscillation motor 8 causes the vibration box to vibrate.
[0023] In this embodiment, four support feet 1 are provided. The vibration box 2 is installed on the support feet 1 by shock-absorbing springs 7. The shock-absorbing springs 7 play a certain buffering role and can reduce the vibration impact of the vibration box on the support feet during operation.
[0024] In this embodiment, a rectangular conical discharge channel 22 with a larger top and smaller bottom and a rectangular cross-section is provided in the vibrating box 2 below the secondary screen 9. The lower end of the rectangular conical discharge channel 22 is connected to the bottom discharge port 14. The rectangular conical discharge channel 22 is more conducive to material discharge.
[0025] In this embodiment, a rubber sealing cover (not shown in the figure) is provided in the rectangular through hole 21 at the top of the vibration box 2. When the flushing component 4 is not working, the rubber sealing cover seals the rectangular through hole 21 to prevent debris from entering the vibration box 2.
[0026] In this embodiment, a water collection tank 13 is also included, and the water suction pipe 44 extends into the water collection tank. When the rinsing assembly is working, it draws water from the water collection tank 13 to perform the rinsing operation. The water collection tank can be placed on the ground or placed on a separate support. Alternatively, the water collection tank can be omitted, and the water suction pipe can draw water from other containers filled with water.
[0027] Working process: During operation, connect motor 41 and vibrating motor 8 to the external power supply. Put the tea leaves into the vibrating box 2 through the feed inlet 3, and then start the vibrating motor 8 to make the vibrating box 2 start to vibrate. The support spring 12 drives the primary screen 10 and the secondary screen 9 to vibrate and screen the tea leaves. First, some of the tea leaves on the primary screen 10 fall onto the secondary screen 9. Since the primary and secondary screens are set at an incline, the tea leaves that cannot pass through the primary screen slide down the slope and are discharged from the upper discharge outlet 5. Then, some of the tea leaves on the secondary screen fall off and are discharged from the bottom discharge outlet 14. The tea leaves that cannot pass through the secondary screen are discharged from the lower discharge outlet 6, thus completing the grading and screening of the tea leaves.
[0028] When the screening is complete and the vibrating box needs to be rinsed, the water pump 45 is started to draw water from the water collection tank 13 through the water suction pipe 44, and then enters the water collection column 48 through the hose 43 and the water delivery pipe 42, and is sprayed out through the nozzle 47. At the same time, the motor 41 is started so that its output end drives the lead screw 410 to rotate, thereby moving the water collection column 48 from one end of the vibrating box to the other end to rinse the primary and secondary screens, prevent the tea from absorbing flavors, improve the quality of the tea and the practicality of the screening device.
