Description

Technical Field

[0001] This utility model relates to the field of tea sieving technology, specifically a tea shaking machine for tea sieving. Background Technology

[0002] In the tea processing industry, sieving is a key step in improving the quality and commercial value of tea. Its core lies in removing impurities and separating tea particles of different sizes through grading and screening, laying the foundation for subsequent refining, packaging and other processes. Traditional tea sieving relies heavily on manual operation, with operators holding a sieve and shaking it back and forth, using the differences in sieve aperture to grade the tea. However, this method is not only labor-intensive and inefficient, making it difficult to meet the needs of large-scale production, but the sieving effect is also significantly affected by subjective factors such as the operator's experience and control of force, easily leading to uneven grading and missed sieving, which seriously restricts the standardization and industrialization of tea processing. To address the drawbacks of manual tea sieving, various types of tea sieving machinery have emerged. Existing sieving equipment mostly employs an integrated sieving structure, using a vibrating motor to drive the screen body to vibrate. Centrifugal or inertial force is used to achieve relative movement between the tea leaves and the screen, thus completing the sieving operation. However, this integrated sieving structure is inconvenient for tea discharge. After sieving, the tea leaves on the screen need to be manually removed. Because the tea leaves are laid on the screen during sieving, manual stacking of the tea leaves is required before removal, resulting in high labor costs and low tea discharge efficiency. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a tea shaking machine for tea sieving, thereby solving the shortcomings of the prior art.

[0004] The purpose of this utility model is achieved through the following technical solution: a tea shaking machine for tea sieving, comprising a frame, on which a split sieving assembly is provided, the split sieving assembly comprising a vibrating frame and a sieving frame, the vibrating frame being mounted on the frame and having a reciprocating linear motion degree of freedom, the sieving frame being detachably mounted on the top of the vibrating frame, a screen being installed inside the sieving frame, a feeding window being opened on one side wall of the sieving frame, a baffle being provided inside the feeding window, and the baffle being detachably connected to the sieving frame.

[0005] Furthermore, inverted T-shaped blocks are fixed at the four corners of the bottom of the vibration frame, and inverted T-shaped grooves are opened at the top of the frame at the positions corresponding to the inverted T-shaped blocks. The inverted T-shaped blocks are slidably disposed in the inverted T-shaped grooves, and springs are disposed in the inverted T-shaped grooves. The two ends of the springs are respectively connected to the frame and the inverted T-shaped blocks.

[0006] Furthermore, a main shaft is rotatably mounted on the frame, the axis of the main shaft is vertically set, the main shaft is located at one end of the vibration frame, a cam is fixedly mounted on the main shaft, the cam contacts the vibration frame, a motor is mounted on the frame, and the output shaft of the motor is drivenly connected to one end of the main shaft.

[0007] Furthermore, one side of the screening frame is hinged to the vibrating frame via a hinge, and a plurality of first connecting plates are fixed to the other side of the screening frame. The plurality of first connecting plates are arranged at equal intervals along the length direction of the screening frame. A plurality of second connecting plates are fixed to the side wall of the vibrating frame. The plurality of second connecting plates correspond one-to-one with the plurality of first connecting plates. A first insertion hole is formed through the first connecting plate, and a second insertion hole is formed through the second connecting plate. A pin is inserted into both the first insertion hole and the second insertion hole.

[0008] Furthermore, the maximum diameter of the pin is greater than the diameters of the first and second sockets.

[0009] Furthermore, a horizontal plate is fixed to one end of the baffle away from the screening frame. The horizontal plate and the baffle are connected in a T-shape. A hand-tightening screw is provided on the horizontal plate. The tail of the hand-tightening screw moves through the horizontal plate and is threaded onto the screening frame.

[0010] The beneficial effects of this utility model are: 1. During feeding, remove the baffle to open the feeding window, then tilt the screening frame to an inclined position. At this point, the feeding window is at the lower end, allowing the tea leaves to quickly gather at the bottom of the screening frame due to gravity, enabling rapid discharge. The feeding window also facilitates the removal of any remaining tea leaves, eliminating the cumbersome manual stacking and removal required in traditional integrated screening structures. This eliminates the need for manual cleaning, reducing labor costs.

[0011] 2. The design adopts a vibrating frame to drive the screening frame to make reciprocating linear motion. With the help of vibration, the tea leaves move fully on the screen, which accelerates the separation of tea particles of different sizes and greatly improves the screening efficiency.

Detailed Implementation

[0013] Example 1 like Figures 1 to 3 As shown, a tea-shaking machine for tea sieving includes a frame 1, on which a split-type sieving assembly is mounted. The split-type sieving assembly includes a vibrating frame 2 and a sieving frame 3. The vibrating frame 2 is mounted on the frame 1 and has a reciprocating linear motion degree of freedom. The sieving frame 3 is detachably mounted on the top of the vibrating frame 2, i.e., one side of the sieving frame 3 is hinged to the vibrating frame 2. A screen 4 is installed inside the sieving frame 3. A feeding window is opened on one side wall of the sieving frame 3, and a baffle 5 is installed inside the feeding window. The baffle 5 is detachably connected to the sieving frame 3. Tea leaves to be sieving are fed into the sieving frame 3. During sieving, the sieving frame 3 is connected to the vibrating frame 2, causing the vibrating frame 2 to drive the sieving frame 3 in a reciprocating linear motion. The vibration mechanism allows the tea leaves to move freely on the screen 4, accelerating the separation of tea particles of different sizes and significantly improving screening efficiency. After screening, the baffle 5 is removed, opening the discharge window. Then, the screening frame 3 is tilted, placing the discharge window at its lowest position. This allows the tea leaves to quickly gather at the bottom of the screening frame 3 under their own weight, enabling rapid discharge. Some tea leaves may remain on the side wall at the bottom of the screening frame 3. The discharge window allows workers to easily push out the remaining tea leaves, eliminating the cumbersome manual stacking and removal required in traditional integrated screening structures. This eliminates the need for manual cleaning, reducing labor costs.

[0014] Example 2 Based on Example 1, such as Figure 1 and Figure 2As shown, multiple first connecting plates 12 are fixed on the other side of the screening frame 3. These first connecting plates 12 are arranged at equal intervals along the length of the screening frame 3. Multiple second connecting plates 13 are fixed to the side wall of the vibrating frame 2. Each second connecting plate 13 corresponds one-to-one with a first connecting plate 12. A first insertion hole is formed through the first connecting plate 12, and a second insertion hole is formed through the second connecting plate 13. A pin 16 is simultaneously inserted into both the first and second insertion holes. The maximum diameter of the pin 16 is larger than the diameters of the first and second insertion holes. The pin 16 connects the screening frame 3 and the vibrating frame 2 together. The length of the pin 16 passing through the second insertion hole is greater than 5cm. Since the vibrating frame 2 moves in a reciprocating linear motion in the horizontal direction, the vibration generated will not cause the pin 16 to move significantly in the vertical direction. The length of the pin 16 passing through the hole is greater than 5cm, which ensures that the pin 16 does not detach from the first connecting plate 12 and the second connecting plate 13. This ensures that the connection between the screening frame 3 and the vibrating frame 2 is stable during screening. After screening is completed, the pin 16 can be removed upwards and the screening frame 3 can be rotated to complete the discharge of the tea leaves.

[0015] Example 3 Based on Example 2, such as Figure 1 and Figure 2 As shown, a horizontal plate 14 is fixed to the end of the baffle 5 away from the screening frame 3. The horizontal plate 14 and the baffle 5 are connected in a T-shape. A hand screw 15 is provided on the horizontal plate 14. The tail of the hand screw 15 moves through the horizontal plate 14 and is threaded onto the screening frame 3. The baffle 5 can be removed by loosening the hand screw 15 to separate it from the screening frame 3. During installation, the hand screw 15 is tightened onto the screening frame 3. The operation is simple and quick.

[0016] Example 4 Based on Example 3, such as Figures 1 to 3 As shown, inverted T-shaped blocks 6 are fixed at the four corners of the bottom of the vibration frame 2. An inverted T-shaped groove 7 is formed at the top of the frame 1 at the corresponding position of the inverted T-shaped block 6. The inverted T-shaped block 6 is slidably disposed within the inverted T-shaped groove 7. A spring 8 is disposed within the inverted T-shaped groove 7, with both ends of the spring 8 connected to the frame 1 and the inverted T-shaped block 6 respectively. A main shaft 9 is rotatably mounted on the frame 1, with its axis vertically positioned. The main shaft 9 is located at one end of the vibration frame 2. A cam 10 is fixedly mounted on the main shaft 9, and the cam 10 contacts the vibration... A motor 11 is mounted on frame 2 and frame 1. The output shaft of motor 11 is connected to one end of main shaft 9. Motor 11 drives main shaft 9 to rotate, and main shaft 9 drives cam 10 to rotate. The distal end of cam 10 pushes vibrating frame 2 to move. Vibrating frame 2 drives inverted T-shaped block 6 to squeeze spring 8 to move. When the distal end of cam 10 moves away from vibrating frame 2, vibrating frame 2 returns to its original position under the reaction force of spring 8. This process repeats, and the vibration of vibrating frame 2 is generated by the cooperation of cam 10 and spring 8 in reciprocating linear motion.
