Abstract
Description
Technical Field
[0001] This utility model belongs to the field of tea screening technology, specifically relating to a tea vibration screening machine. Background Technology
[0002] The main purpose of tea screening is to ensure the quality and taste of tea. By screening, impurities and defective leaves are removed, improving the purity and overall quality of the tea. At the same time, screening also helps to classify tea into different grades to meet the needs of different consumers. The screening intensity should be reasonably controlled according to the type and quality characteristics of the tea to avoid excessive screening that would lead to a decline in tea quality. During the tea screening process, the screen is vibrated, allowing the tea leaves to flow along the screen and be sorted. Tea leaves that meet the requirements are sieved and flow out, while those that do not meet the requirements are intercepted and moved to the end of the screen to flow out. Because tea leaves are relatively soft, the mesh of the screen is easily clogged after screening. At this time, workers need to help clean the mesh one by one, which is time-consuming and inconvenient. Therefore, the inventor proposes a tea vibrating screening machine. Utility Model Content
[0003] (1) Technical problems to be solved
[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a tea vibrating screening machine, which aims to solve the problem that after the tea leaves are screened, the mesh of the screen is easily clogged with tea leaves.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] This specific embodiment is a tea vibrating screening machine, the structural diagram of which is shown below. Figure 1 , Figure 2 As shown, the screen includes a main body 1, a cleaning wheel 9, and a feed hopper 5. The upper surface of the main body 1 has a removable cover 4, and the end of the cover 4 is provided with a feed hopper 5 that communicates with the main body 1. The lower end of the main body 1 away from the feed hopper 5 is provided with a first discharge port 7 and a second discharge port 8. A screening screen 6 is installed inside the main body 1. A vibrating motor 3 connected to the screening screen 6 is installed at the lower part of the main body 1. The cleaning wheel 9 is horizontally arranged inside the main body 1. The surface of the cleaning wheel 9 has a brush. Hangers 10 are respectively fitted on both sides of the cleaning wheel 9 near the end. The hangers 10 are rotatably connected to the cleaning wheel 9. A drive shaft 11 is fixedly connected to the center of the end face of the cleaning wheel 9. A drive gear 12 is fixedly connected to the end of the drive shaft 11 away from the cleaning wheel 9.
[0024] like Figure 3 As shown, a drive rod 14 is horizontally mounted below the drive gear 12, and the drive rod 14 is fixedly connected to the inner wall of the screening machine body 1. The upper surface of the drive rod 14 has an array of toothed grooves 13, which are adapted to the drive gear 12.
[0025] like Figure 4As shown, a movable plate 15 is fixedly connected to the upper surface of the hanger 10. The movable plate 15 is horizontally positioned, and sliders 16 are fixedly connected to its two ends. A horizontal groove 17 is formed on the inner wall of the screening machine body 1, and the sliders 16 are fitted into the groove 17. A drive screw 18 is horizontally rotatably mounted inside the groove 17, and the drive screw 18 is threaded through the slider 16. Support columns 2 are provided around the perimeter of the screening machine body 1.
[0026] Working Principle: In operation, the tea leaves to be screened are first poured into the main body 1 of the screening machine from the feed hopper 5. The vibration motor 3 is then started, applying vibration force to the screening screen 6. As the screening screen 6 slides, the tea leaves on its surface move towards the first discharge port 7 and the second discharge port 8. During this movement, some tea leaves pass through the screening screen 6 and are discharged from the second discharge port 8, while the tea leaves that do not pass through the screening screen 6 move to the end of the screen 6 and fall through the first discharge port 7. After the tea leaves are screened, the screening screen 6 stops vibrating. At this time, the drive screw 18 starts (driven by a motor, not shown in the figure), and... The slider 16, threadedly connected to the drive screw 18, slides along the slide groove 17, thereby driving the moving plate 15 to move. The cleaning wheel 9 below the moving plate 15 is then subjected to force and begins to move. During the movement of the cleaning wheel 9, the drive gear 12 at the end contacts the drive rod 14, and the drive gear 12 rotates in conjunction with the tooth groove 13. The cleaning wheel 9 also rotates on its own during the movement, thereby cleaning the mesh of the screening screen 6 through the brush on the surface of the cleaning wheel 9, sweeping out the clogged and clump-like tea leaves. The cleaning wheel 9 moves back and forth horizontally until all the tea leaves on the surface of the mesh are cleaned. Then the cleaning wheel 9 can move to the side position to complete the tea leaf screening operation.
[0027] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
