Description
Technical Field
[0001] The utility model relates to the technical field of tea processing, and particularly relates to a screening device for layered collection of tea leaves used in tea processing. Background Art
[0002] Tea refers to the leaves and buds of the tea tree. Its aliases include tea, jia, ming, and chuan. Generally, it refers to the leaves of the evergreen shrub tea tree that can be used for making tea, as well as the beverages brewed with these leaves. Later, it was extended to all herbal teas brewed with the flowers, leaves, seeds, and roots of plants, such as "chrysanthemum tea", etc.; "herbal teas" brewed with various medicinal materials, etc. It is also called thunder buds in Chinese literature. In some countries, there are also teas brewed with the leaves of other plants such as fruits and herbs, such as "fruit tea". The habit of drinking tea originated in China. The leaves are leathery, oblong or elliptical, and can be directly brewed with boiling water. They are divided into six categories according to the variety, production method, and product shape. According to the season of collection, they can be divided into spring tea, summer tea, autumn tea, and winter tea. Various semi-finished teas or refined tea leaves are further processed to form reprocessed tea, including scented tea, compressed tea, extracted tea, medicinal and health care tea, tea-containing beverages, etc.
[0003] For the common screening devices for layered collection of tea leaves used in tea processing on the market, in order to improve the screening efficiency, most of them use stirring rods to scrape the tea leaves to promote the screening efficiency. However, during the stirring process, the stirring rods are likely to cause impact damage to the tea leaves, making them break and affecting the quality of the tea leaves.

[0031] The center of the back side of the rotating disk 10 is fixedly connected to the output end of the driving motor 12, and the outer wall of the driving motor 12 is fixedly connected to the inner wall of the mounting frame.
[0032] Example 2
[0033] like Figure 1-5 As shown, on the basis of Example 1, the utility model provides a technical solution: preferably, a cover tube is fixedly connected to the center of the bottom of the inner wall of the first screening plate 5, the top of the inner wall of the cover tube is fixedly connected to the top of the vibration spring 16, the inner wall of the vibration spring 16 is movably connected to the outer wall of the center rod 9, the outer wall of the center rod 9 is movably connected to the mounting collar 17, and the outer wall of the mounting collar 17 is fixedly connected to the inner wall of the top end of the cover tube.
[0034] The bottom end of the vibration spring 16 is fixedly connected to the upper surface of the bottom ring 13 , the inner wall of the bottom ring 13 is movably connected to the outer wall of the center rod 9 , and the bottom surface of the bottom ring 13 overlaps the upper surface of the upper push ring 15 .
[0035] The inner wall of the upper push ring 15 is fixedly connected to the outer wall of the center rod 9, and the bottom surface of the first screening plate 5 is fixedly connected with a protective cover 14, which can protect the vibrating components of the first screening plate 5 to prevent tea leaves from getting stuck and being difficult to remove.
[0036] Example 3
[0037] like Figure 1-5 As shown, on the basis of Example 1, the utility model provides a technical solution: preferably, the bottom end of the delivery bucket 4 is fixedly connected to the upper surface of the screening drum 1, and the inner wall of the delivery bucket 4 is fixedly connected with a guide cone 18. The bottom surface of the screening drum 1 is fixedly connected to the upper surface of the base 3, the outer walls of the first screening plate 5 and the second screening plate 6 are movably connected to the inner wall of the screening drum 1, and the bottom surface of the collecting bottom plate 7 is fixedly connected to the bottom of the inner wall of the screening drum 1.
[0038] The working principle of the screening device for collecting tea leaves in layers for tea processing will be described in detail below.
[0039] like Figure 1-5As shown, when in use, the tea leaves to be screened are put into the screening cylinder 1 through the putting bucket 4. During the putting process, the tea leaves will be dispersed and fall under the guidance of the guide cone 18.
[0040] When the tea leaves are put in, the external power supply starts the driving motor 12, so that the driving motor 12 drives the rotating disk 10 to rotate. During the rotation process, the rotating disk 10 will push the center rod 9 up and down through the linkage rod 11. During the up and down movement of the center rod 9, the upper push ring 15 will be pushed up. At this time, the upper push ring 15 will push the bottom ring 13 to move up and compress the vibration spring 16, so that the vibration spring 16 generates elastic force. When the center rod 9 drives the upper push ring 15 to move downward, the first screening plate 5 drives the vibration spring 16 to move downward due to gravity. At this time, the center rod 9 drives the upper push ring 15 to move upward again, and squeezes the vibration spring 16 again, so that the first screening plate 5 is reciprocated by the vertical elastic force of the vibration spring 16 and the upward pushing force of the upper push ring 15, forming a vibration effect, thereby screening the tea leaves.
[0041] The second screening plate 6 also acts synchronously to perform secondary screening, and increasing the amplitude only requires increasing the output of the drive motor 12 .
[0042] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
