Description

Technical Field

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

[0002] Tea contains catechins, cholestenone, caffeine, inositol, folic acid and pantothenic acid.

[0003] In the process of processing tea, in order to improve the grade and appearance of tea, the tea needs to be screened.

[0025] In this embodiment, a certain amount of tea leaves are put into the material box 3, and the vibration mechanism 6 is started through the controller. Under the action of the connecting mechanism 4, the two screen frames 5 are driven to vibrate, so that the tea leaves falling into the screen frames 5 are well screened, and the screened tea leaves fall into different collection boxes 7 respectively. At the same time, the air selection mechanism 8 is started through the controller to clean the screened tea leaves that are heavier than the tea leaves, thereby realizing the air selection and cleaning of heavier impurities, and effectively improving the screening accuracy and processing efficiency.

[0026] In a further preferred embodiment of the utility model, the connecting mechanism 4 includes: a mounting groove 401 provided on the mounting plate 2; a connecting rod 402 fixedly installed in the mounting groove 401; a connecting block 403 slidably arranged on the connecting rod 402, and the connecting block 403 is fixedly connected to the outer wall of the screen frame 5; and a spring 404 sleeved on the connecting rod 402.

[0027] In this embodiment, when the vibration mechanism 6 drives the screen frame 5 to vibrate, under the action of the connecting mechanism 4, the screen frame 5 can be stably vibrated, thereby improving the stability of the screen frame 5 during the vibration process.

[0028] In a further preferred embodiment of the utility model, the vibration mechanism 6 includes: a dual-axis motor 601 mounted on the mounting plate 2 (the rotation speed of the dual-axis motor 601 can be controlled and adjusted according to actual conditions); two mounting shafts 602 respectively fixedly mounted on the two output shafts of the dual-axis motor 601; two connecting shafts 603 respectively mounted on one side of the dual-axis motor 601, and a support block is fixedly mounted on one side of the mounting plate 2, and the support block and the connecting shaft 603 are rotatably connected; four bevel gears 604 respectively fixedly mounted on the two mounting shafts 602 and the two connecting shafts 603, and the four bevel gears 604 are meshed with each other in pairs; two cams 605 respectively fixedly mounted on the two connecting shafts 603; two placement blocks 606 respectively fixedly mounted on both sides of the bottom of one of the screen frames 5, and the two placement blocks 606 are respectively located above the two cams 605, and the placement blocks 606 and the cams 605 are adapted to each other.
