Description

Technical Field

[0001] This utility model relates to the field of tea sieving and testing technology, and in particular to a sieving device for tea testing. Background Technology

[0002] Tea leaves are the leaves and buds of the tea plant, processed through a series of steps including picking and processing. A tea sieving device is a specialized piece of equipment used for sieving and testing tea leaves. Its main function is to classify tea leaves according to different particle sizes, shapes, and other characteristics, in order to assess and test the quality of the tea. By using a sieving device, tea leaves can be classified according to different particle sizes and shapes, thus allowing for a more accurate evaluation of tea quality.

[0003] Patent document CN212550453U discloses a broken tea sieving device for tea quality testing, including a sieving machine. A vibrating motor is fixedly connected to the lower surface of the sieving machine. Inside the sieving machine, a third sieving screen, a second sieving screen, and a first sieving screen are installed sequentially from top to bottom. A cover plate is installed on the upper surface of the sieving machine, and a sieving component is fixedly connected to the upper surface of the cover plate. Two fastening plates are fixedly connected to the upper surface of the cover plate, and fastening components are embedded in the side surfaces of the fastening plates. The sieving component ensures that the accumulated tea leaves are evenly distributed, thereby removing broken tea leaves and improving the quality of the tea. The fastening components allow for the fixing of the first, second, and third sieving screens by adjusting the fixing blocks and tightening the fixing screws, enabling the sieving screens to be disassembled and installed easily, saving time and effort, and facilitating the removal of the screens for cleaning and replacement, thus improving the quality of the tea.

[0004] When using the above technology, the following technical problems were found in the existing technology: the above technical solution only rotates and screens the tea leaves in the horizontal direction. This single movement mode makes the contact opportunity between the tea leaves and the screen holes relatively limited. The tea leaves may concentrate in a certain part of the screen frame, which increases the probability of the screen holes being blocked by the tea leaves. Therefore, a tea leaf screening device is designed to provide another technical solution to the above technical problems. Utility Model Content

[0005] Therefore, it is necessary to provide a tea sieving device to address the above-mentioned technical problems. This device solves the problem that the above-mentioned technical solutions only perform horizontal rotation sieving of tea leaves. This single movement mode results in relatively limited contact between the tea leaves and the sieve holes, and the tea leaves may concentrate in a certain part of the sieve frame, increasing the probability that the sieve holes in that part will be blocked by the tea leaves.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] A tea sieving device includes a support frame. A motor is fixedly connected to the outer wall of the support frame. A drive shaft is fixedly installed at the output end of the motor. One end of the drive shaft is rotatably connected to the inside of the support frame. A rotating ring is fixedly connected to the other end of the drive shaft.

It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0028] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0029] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0030] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0031] Reference Figures 1-6 A tea sieving device includes a support frame 1. A motor 2 is fixedly connected to the outer wall of the support frame 1, providing support and fixation for the motor 2. A drive shaft 3 is fixedly installed at the output end of the motor 2. One end of the drive shaft 3 is rotatably connected inside the support frame 1, providing support for the drive shaft 3. A rotating ring 4 is fixedly connected to the other end of the drive shaft 3. A rotating rod 5 is slidably connected inside the rotating ring 4. A fixed shaft 6 is fixedly connected to the end of the rotating rod 5 away from the rotating ring 4, connecting the rotating ring 4 and the fixed shaft 6. Rotating blocks 7 are rotatably connected to the top and bottom of the fixed shaft 6. A first support shaft 8 is fixedly connected inside the rotating block 7, with both ends of the first support shaft 8 rotatably connected inside the support frame 1. A sieve frame 9 is fixedly connected to the outer wall of the rotating block 7. A sieve plate 10 is detachably connected inside the sieve frame 9. A back plate 23 is fixedly connected inside the support frame 1. A sliding column 24 is fixedly connected to the outer wall of the sieve frame 9, with the outer wall of the sliding column 24 slidably connected to the inner wall of the back plate 23. A fixing component 11 is provided on the outer wall of the support frame 1.

[0032] The usage process of the tea sieving device provided by this utility model is as follows:

[0033] When tea leaves need to be sieved, motor 2 is started. Driven by motor 2, the transmission shaft 3 rotates stably inside the support frame 1. The transmission shaft 3 fixes the rotating ring 4. When the transmission shaft 3 rotates, it drives the rotating ring 4 to rotate as well. The rotating ring 4 supports the rotating rod 5. Due to the arc-shaped design of the rotating ring 4, when the rotating ring 4 rotates, the rotating rod 5 will slide inside it while rotating. The rotating rod 5 fixes the fixed shaft 6, thus driving the fixed shaft 6 to rotate synchronously. The fixed shaft 6 connects the rotating rod 5 and the rotating block 7. The rotating block 7 rotates synchronously with the rotation of the fixed shaft 6. The rotating block 7 has a sliding groove inside, which does not affect the rotation of the rotating rod 5. The rotating block 7 fixes the first support shaft 8, allowing it to rotate stably inside the support frame 1. The rotating block 7 also fixes the sieve frame 9. When block 7 rotates, it drives the screen frame 9 to rotate synchronously. The screen frame 9 and screen plate 10 are detachably connected and fixed by bolts. When the bolts are removed, the screen plate 10 can be removed from the inside of the screen frame 9 and replaced with a screen plate 10 with a different sieving aperture. The rotation of the screen frame 9 and screen plate 10 causes the tea to vibrate and be sieved. The screen frame 9 fixes the sliding column 24 and can drive the sliding column 24 to slide against the groove opened inside the back plate 23. The groove opened inside the back plate 23 is the same as the rotation trajectory of the screen frame 9, which can provide auxiliary support for the screen frame 9 and improve the stability of the screen frame 9. At the same time, this oscillating sieving design can also prevent the tea leaves at the bottom of the screen frame 9 from clogging the screen holes. The detachable connection design makes it easy to replace the screen plate 10 with different apertures to meet different sieving needs. Through vibration, the tea leaves are evenly distributed in the screen frame 9, reducing the accumulation and clogging of tea leaves during the sieving process and improving sieving efficiency.

[0034] Reference Figure 1 The fixing component 11 includes a fixing plate 1101. The outer wall of the fixing plate 1101 is fixedly connected to the outer wall of the support frame 1. A connecting plate 1102 is fixedly connected to the outer wall of the fixing plate 1101. The fixing plate 1101 is fixed to the outer wall of the support frame 1 and plays a supporting and fixing role for the connecting plate 1102.

[0035] The usage process of the tea sieving device provided by this utility model is as follows:

[0036] The fixing plate 1101 serves to fix both the support frame 1 and the connecting plate 1102, acting as a support for the entire device and ensuring stability during the tea sieving process.

[0037] Reference Figure 1 , Figure 5 and Figure 6A support block 12 is fixedly connected to the upper surface of the connecting plate 1102. An electric push rod 13 is fixedly connected inside the support block 12. The support block 12, fixed to the upper surface of the connecting plate 1102, supports and fixes the electric push rod 13. A discharge cylinder 14 is fixedly connected to the output end of the electric push rod 13. A sealing cover 15 is provided on the lower surface of the discharge cylinder 14. The lower surface of the sealing cover 15 is slidably connected to the upper surface of the connecting plate 1102. A sliding plate 16 is fixedly connected to the upper surface of the discharge cylinder 14, and the discharge cylinder 14 fixes the sliding plate 16. The slide plate 16 has a discharge port 17 inside; limit strips 18 are fixedly connected to both sides of the slide plate 16, and the slide plate 16 fixes the limit strips 18. A fixing frame 19 is slidably connected to the outer wall of the limit strips 18, and the outer wall of the fixing frame 19 is fixedly connected to the outer wall of the fixing plate 1101; a fixing ring 20 is fixedly connected to the outer wall of the fixing plate 1101, and a storage tank 21 is fixedly connected inside the fixing ring 20; the lower surface of the storage tank 21 is slidably connected to the upper surface of the slide plate 16, and a discharge cylinder 22 is fixedly connected to the top of the storage tank 21.

[0038] The usage process of the tea sieving device provided by this utility model is as follows:

[0039] When tea leaves need to be sieved for testing, the tea leaves are added into the sieve frame 9. The electric push rod 13 is activated to push the discharge cylinder 14 to slide. The discharge cylinder 14 fixes the slide plate 16. When the discharge cylinder 14 slides, it causes the slide plate 16 to slide accordingly. Limiting strips 18 are provided on both sides of the slide plate 16. When the slide plate 16 slides, it causes the limiting strips 18 to slide against the inner wall of the fixed frame 19, thus limiting the sliding of the discharge cylinder 14 so that it can only slide horizontally and will not deviate. The diameter of the discharge port 17 on the slide plate 16 is the same as the size of the through holes at the bottom of the storage tank 21 and inside the discharge cylinder 14. The tea leaves to be tested inside the storage tank 21 enter the discharge cylinder 14 through the discharge port 17. When the discharge cylinder 14 slides, it causes the tea leaves inside to slide synchronously. At this time, the tea leaves inside are sealed by the sealing cap 15. 4. When sliding, the sealing cover 15 will also slide. The discharge cylinder 14 and the sealing cover 15 are connected by a hinge. The sealing cover 15 will slide on the upper surface of the connecting plate 1102. When the sealing cover 15 slides out of the connecting plate 1102, the sealing cover 15 will rotate, causing the tea leaves inside the discharge cylinder 14 to fall into the sieve frame 9 for subsequent sieving. At the same time, the other side of the slide plate 16 will slide to the bottom of the storage tank 21 to seal the tea leaves inside the storage tank 21. The tea leaves are quantitatively fed by the sliding of the discharge cylinder 14. The top of the storage tank 21 is fixed with a feeding cylinder 22, which facilitates the addition of tea leaves into the storage tank 21. Automatic quantitative feeding can ensure that the amount of tea sample tested each time is consistent, reduce the detection error caused by inconsistent sample amount, and also reduce the workload of operators in the sampling process.

[0040] In this embodiment, each structure has its own service life. In actual manufacturing and application, the corresponding structure made of different materials can be replaced according to the needs of use.

[0041] In this embodiment, the motor is a self-locking motor, which can drive the connected structure to rotate normally when it is powered on and working. When the motor stops working, it can prevent the connected structure from rotating through its self-locking function.

These preferred embodiments do not exhaustively describe all details, nor do they limit the present utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification.
