Description

Technical Field

[0001] This utility model belongs to the field of tea sieving technology, and in particular relates to a raw tea shaking sieving machine. Background Technology

[0002] Existing tea sieving equipment requires cleaning the screens after a period of operation to remove impurities clogging the mesh. Cleaning necessitates stopping the equipment and vibrating the screen by tapping it. However, for better cleaning results, the screen needs to be removed, turned upside down, and then vibrated by tapping again for thorough cleaning. Regardless of the method used, cleaning the screen requires stopping the equipment and manual labor, making the process cumbersome and impacting production schedules. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a tea sieve shaker that can automatically clean the mesh of the sieve plate without stopping the machine, making the cleaning process more convenient and the structure simple.

[0004] In order to achieve the purpose of this utility model, the following solution is proposed: A tea leaf shaking and sieving machine includes: a machine casing and a rotary screen.

[0005] The bottom of the machine casing has parallel debris holes and finished product holes, with a partition between the debris holes and finished product holes. The top of the machine casing has a feeding port aligned with the debris holes.

[0006] The rotary screen includes a main shaft, with an even number of screen plates arranged in a circular array around its exterior. The main shaft is positioned parallel above the partition plate. The rotary screen is housed inside the casing and rotates around the main shaft. When the rotary screen rotates, there is a gap between the edge of the screen plate and the top surface of the partition plate.

[0007] The beneficial effects of this utility model are as follows: while discharging qualified tea leaves, the sieve plate can be automatically flipped and the sieve can be cleaned by vibration, without the need for manual cleaning or disassembly of the sieve plate. Attached Figure Description

[0018] like Figures 1 to 3 As shown, a tea shaking and sieving machine includes: a machine casing 1 and a rotary screen 2.

[0019] Specifically, such as Figure 1 , Figure 2As shown, the bottom of the housing 1 is provided with a debris hole 11 and a finished product hole 12 that are parallel to each other. A partition 13 is provided between the debris hole 11 and the finished product hole 12. The top of the housing 1 is provided with a feeding port 14 that is aligned with the debris hole 11.

[0020] Specifically, such as Figure 2 , Figure 3 As shown, the rotary screen 2 includes a main shaft 21, with an even number of screen plates 22 arranged in a circular array around its exterior. The main shaft 21 is parallel to and positioned above the partition plate 13. The rotary screen 2 is housed inside the casing 1 and rotates around the main shaft 21. Specifically, both ends of the main shaft 21 are rotatably mounted on the casing 1, and there is a gap between the edges of the screen plates 22 and the top surface of the partition plate 13 when the rotary screen 2 rotates. One end of the main shaft 21 is connected to a drive motor 4, which is located on the outer wall of the casing 1.

[0021] During operation, the main shaft 21 is rotated so that one of the sieve plates 22 is horizontally positioned above the impurity hole 11. Then, the raw tea is fed into the feed port 14. The main shaft 21 is then rotated back and forth within a small angle range. As a preferred embodiment, the reciprocating rotation range of the main shaft 21 is less than 5 degrees, which causes the sieve plate 22 to vibrate, thereby achieving the purpose of shaking and screening the raw tea. The fine impurities and broken tea leaves after screening will fall directly into the impurity hole 11 below. After the main shaft 21 has been rotating back and forth for a predetermined time, it continues to rotate, causing the sieve plate 22 containing the tea leaves to move upward. When the sieve plate 22 moves above the finished product hole 12, the qualified tea leaves on it will automatically fall and be discharged from the finished product hole 12 and collected in a container. At this time, the sieve plate 22 is in a flipped state. The main shaft 21 can be rotated back and forth again to vibrate the sieve plate 22, thereby shaking off the impurities and broken tea leaves clogging the mesh, thus achieving the effect of cleaning the sieve plate 22.

[0022] The above solution allows for cleaning of the screen without stopping the machine or disassembling the screen plate 22, which effectively simplifies the cleaning process and improves screening efficiency.

[0023] Preferred, such as Figure 2 , Figure 3 As shown, the sieve plate 22 has baffles 221 on the periphery of the side facing the rotation direction to gather the tea leaves and prevent them from scattering during the vibrating sieving process.

[0024] Preferred, such as Figure 2As shown, the rotary screen 2 has four screens arranged in a circular array along the main shaft 21. With this design, when one screen plate 22 is horizontally positioned above the impurity hole 11, the other screen plate 22 is horizontally positioned above the finished product hole 12. The vibration generated by the reciprocating rotation of the main shaft 21 can not only sieve the raw tea, but also clean the screen plate 22 above the finished product hole 12. Furthermore, the vertically downward-facing screen plate 22 is positioned above the partition plate 13, which can better separate the impurity hole 11 and the finished product hole 12.

[0025] Preferred, such as Figure 4 As shown, a circular tube 23 is coaxially sleeved on the outside of the main shaft 21. Screen plates 22 are all mounted on the circular tube 23. Multiple inner protruding strips 231 are arranged in a circumferential array on the inner wall of the circular tube 23. The same number of outer protruding strips 211 are arranged in a circumferential array on the outer wall of the main shaft 21. The inner and outer protruding strips 231 are staggered and spaced apart. Elastic rings 24 are provided in the intervals between the inner and outer protruding strips 231 and 211. A notch is provided on one side of each elastic ring 24 to allow for sufficient expansion and contraction. The elastic rings 24 are subjected to radial force, and naturally... In the normal state, the relative positions of the main shaft 21 and the circular tube 23 along the circumference remain fixed. When the shaft 21 reciprocates, due to inertia, the circular tube 23 and the screen plate 22 cannot rotate with the main shaft 21 in time. This causes the main shaft 21 and the circular tube 23 to turn in opposite directions along the circumference, and the elastic ring 24 is continuously compressed and stretched. This increases the vibration frequency of the screen plate 22 and improves the efficiency of vibrating screening. When the main shaft 21 rotates at a constant speed, supported by the elastic ring 24, the screen plate 22 and the circular tube 23 can rotate with the main shaft 21 in time.

[0026] Preferred, such as Figure 2 As shown, the top of the housing 1 is provided with a longitudinally arranged push rod 3, which is reciprocated in the vertical direction. The lower end of the push rod 3 has an inclined surface 31, which is used to push the screen plate 22 to swing around the main shaft 21. When the push rod 3 moves downward, so that the inclined surface 31 contacts the edge of one of the screen plates 22, the inclined surface 31 will push the screen plate 22 to swing around the main shaft 21 in the direction in which the inclined surface 31 is facing. At this time, the elastic ring 24 will be compressed. When the push rod 3 is moved upward, the inclined surface 31 will gradually separate from the edge of the screen plate 22. Under the action of the elastic ring 24 restoring its elasticity, the screen plate 22 will swing around the main shaft 21 in the opposite direction to the inclined surface 31. By moving the push rod 3 up and down, the screen plate 22 can swing around the main shaft 21. This method does not require driving the main shaft 21 to rotate back and forth to make the screen plate 22 vibrate. The main shaft 21 is mainly used to drive the screen plate 22 to rotate. The top of the housing 1 is provided with a telescopic device 32 for controlling the movement of the push rod 3. The telescopic device 32 is a cylinder or a linear motor.

[0027] The above description is merely a preferred embodiment of this utility model and does not represent the only or limiting embodiment. Those skilled in the art should understand that various changes or equivalent substitutions made to this utility model without departing from its scope are all within the protection scope of this utility model.
