Description

Technical Field

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

[0002] A tea screening device is a device that can classify tea according to particle size by vibration and a screening mesh surface. This is an important step in tea production because the particle size of tea directly affects the appearance and taste of tea. Consistent particle size of tea helps to improve the overall consistency of the product and makes the tea product more in line with the market and consumer demands.

[0003] Currently, common tea screening devices usually do not have the function of collecting powdery tea, which will cause a certain degree of waste. The tea screening devices on the market cannot effectively remove impurities, which is very troublesome during later screening. At the same time, the presence of impurities will also cause damage to the machine. Moreover, common tea screening devices cannot be moved, and transporting tea back and forth increases costs. Therefore, a tea screening device is proposed for the above problems. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a tea screening device to solve the problems raised in the above background art.

[0023] Please refer to Figures 1-6 , the present utility model provides a technical solution:

[0024] A tea screening device, including a main body 1, a fan 13 and an impurity collection tank 14. The upper end of the main body 1 is provided with a feed inlet 2, the lower end of the main body 1 is provided with a tire 3, and the outer wall of the left end of the main body 1 is successively provided with three discharge structures 4 from top to bottom. The discharge structure 4 includes a discharge port 401, a slider 402, a chute 403 and a support rod 404. The outer wall of the right end of the main body 1 is fixedly connected with a fine powder storage bin 5. One end of the fine powder storage bin 5 is provided with a fine powder discharge port 6. The inside of the main body 1 is successively provided with a first filter screen 7, a second filter screen 8 and a third filter screen 9 from top to bottom. One end of each of the first filter screen 7, the second filter screen 8 and the third filter screen 9 is fixedly connected with a rotating shaft 10. One side of the rotating shaft 10 is rotatably connected with the main body 1. The bottom ends of the first filter screen 7, the second filter screen 8 and the third filter screen 9 are fixedly connected with a vibration structure 11. The vibration structure 11 includes a vibrator 1101 and a base 1102. The inner side of the left wall near the bottom end of the main body 1 is provided with a motor 12. One side of the motor 12 is provided with a fan 13. The bottom end inside of the main body 1 is movably connected with an impurity collection tank 14. One side of the outer wall of the impurity collection tank 14 is provided with a handle 15.

[0025] A support rod 404 is fixedly connected to the bottom end of the discharge port 401. One end of the support rod 404 is fixedly connected to the main body 1. A slider 402 is movably connected inside the discharge port 401. Both sides of the slider 402 are movably connected to a chute 403. One side of the chute 403 is fixedly connected to the main body 1; the bottom end of the vibrator 1101 is fixedly connected to a base 1102. One side of the base 1102 is fixedly connected to the main body 1. The base 1102 can ensure that the vibrator 1101 is fixed more firmly and prevent the vibrator 1101 from accidentally falling off during operation; there are a total of four tires 3, and they are evenly distributed at the bottom of the tea screening device. The four tires 3 can ensure the stability of the movement of the tea screening device, and the even distribution of the tires 3 ensures uniform force on each of them; when the vibration structure 11 is not working, the inclination angles of the first filter screen 7, the second filter screen 8, and the third filter screen 9 are equal to the inclination angle of the discharge port 401. The equal inclination angles can ensure that the screened tea can be smoothly discharged from the discharge structure 4.

[0026] Working process: All the electricity required for this utility model is provided externally. When tea screening is needed, push the tea screening device. Under the action of the tires 3, the main body 1 will drive the whole to move. After reaching the destination, turn on the power supply, close the discharge structure 4, add the picked tea into the feed inlet 2, turn on the vibration structure 11. The base 1102 will protect the vibrator 1101 from falling off. The first filter screen 7, the second filter screen 8, and the third filter screen 9 will vibrate up and down under the action of the rotation shaft 10 under the vibration of the vibration structure 11. Since the discharge structure 4 is closed, the tea will vibrate fully on the filter screen. The tea will be screened downward in sequence according to its shape and size. When the tea passes through the third filter screen 9, the fan 13 will rotate driven by the motor 12. The powdery tea will be blown by the fan 13 into the fine powder storage bin 5. Then the powdery tea will come out from the fine powder discharge port 6. At this time, collect the powdery tea. Since the fan 13 cannot blow the impurities, the impurities will fall into the impurity collection tank 14. After there is no obvious sound of impurities falling, pull the handle 15, and then pull out the impurity collection tank 14 to take out the impurities in it. Then pull the slider 402 upward. The slider 402 will move upward along the direction of the chute 403. At this time, the slider 402 no longer blocks the discharge port 401, and the screened tea will be discharged from the discharge port 401. Supported by the support rod 404, the discharge port 401 will not be crushed. Through the above operations, the screening of the tea is completed.
