[0002] As a traditional Chinese beverage, tea requires extremely high quality control during its processing. As consumers' pursuit of tea quality continues to improve, they not only demand a mellow taste and rich aroma, but also set stringent standards for the appearance, purity, and other indicators of tea. Sieving and conveying, as key links in tea processing, bear the important responsibility of grading tea leaves according to their physical characteristics such as particle size, shape, and weight. This directly affects the uniformity of quality within the same batch of tea. High-quality tea needs to ensure that the particle size is consistent and that no impurities are mixed in in order to obtain a higher premium and reputation in the market.

[0003] Existing screening devices, such as vibrating screens, have fixed screen angles, making it difficult to adapt to the screening needs of different teas. For example, when processing coarse raw materials such as black tea, when the screen angle is fixed and small, the gravitational force of coarse black tea raw materials (large volume and heavy weight) on the screen surface is insufficient to overcome friction and vibration inertia, resulting in slow material movement or even stagnation and accumulation. At the same time, once the conveying direction is fixed, it is difficult to adjust and cannot adapt to the complex production line layout of tea processing plants. Utility Model Content

[0027] See attached document Figure 1 -Appendix Figure 5 The present invention provides a multi-angle adjustable tea sieving and conveying integrated machine, including a sieving support frame assembly 1, a vibrating screen unit 2 inside the sieving support frame assembly 1, a sieving angle adjustment unit 3 outside the vibrating screen unit 2, a conveying direction adjustment unit 4 at one end of the vibrating screen unit 2, the sieving support frame assembly 1 including a base 11, a left support 12 and a right support 13 fixedly provided on the top of the base 11, and a tea vibrating conveying bucket 14 fixedly provided between the left support 12 and the right support 13;

[0028] In this implementation scheme, in order to achieve the purpose of adjustable angle of vibrating screen body 21 and adjustable conveying direction of tea reversing conveying bucket 45, the tilt angle of the left end of 3 pairs of 21 is adjusted, and the orientation of 4 pairs of 45 is adjusted. When the tea is being screened and conveyed: the tea to be screened is placed on the vibrating screen body 21, the vibrator in the vibrating screen body 21 is turned on, and under the action of vibration, the tea is screened on the vibrating screen body 21 and conveyed to the bottom. The tea is screened on the vibrating screen body 21, and tea of ​​different sizes and shapes falls into the tea vibrating conveying bucket 14 below through the screen holes. The tea that is not screened enters the tea reversing conveying bucket 45 through the tea conveying bucket 41 and is conveyed to the designated position according to the set conveying direction.

[0029] To achieve adjustable tilt angle of the vibrating screen body 21, the device employs the following technical solution: The vibrating screen unit 2 includes a vibrating screen body 21. Connecting shafts 22 and movable shafts 23 are fixedly mounted on both sides of the vibrating screen body 21. The screening angle adjustment unit 3 includes an electric push rod 31. A connecting frame 32 is fixedly connected to the output end of the electric push rod 31. Two connecting plates 33 are fixedly connected to the bottom of the connecting frame 32. The electric push rod 31 is located at the top of the left support 12 and is fixedly connected to the top of the left support 12. The output end of the electric push rod 31 passes through the top of the left support 12 and is slidably connected to the top of the left support 12. A slot is opened inside the connecting plate 33, which contacts the inner wall of the left support 12 and is slidably connected to the left support 12. One end of the movable shaft 23... Extending into the groove inside the connecting plate 33 and slidingly connected to the groove, when adjusting the screening angle: start the electric push rod 31, the output end of the electric push rod drives the connecting frame 32 and the connecting plate 33 to slide longitudinally on the inner wall of the left support 12. Since the connecting shaft 22 is connected to the right support 13 through the bearing, the movable shaft 23 slides in the groove inside the connecting plate 33. As the connecting plate 33 rises and falls, the vibrating screen body 21 vibrating screen plate rotates around the connecting shaft 22 to achieve the adjustment of the tilt angle. After adjusting to the appropriate angle, the self-locking characteristic of the electric push rod 31 worm gear locks the angle of the vibrating screen body 21 vibrating screen plate to prevent the angle from changing due to the weight of the tea leaves.

[0030] To achieve adjustable conveying direction of the tea-conveying hopper 45, the device employs the following technical solution: The conveying direction adjustment unit 4 includes a tea-conveying hopper 41. A fixing block 42 is fixedly installed at the bottom of the tea-conveying hopper 41, and a threaded hole 43 is provided inside the fixing block 42. A tea-conveying hopper 45 is provided outside the connecting column 44. A connecting sleeve 46 is fixedly installed inside the tea-conveying hopper 45. A reversing disc 47 is fixedly installed outside the tea-conveying hopper 45, and multiple insertion holes 48 are provided inside the reversing disc 47. Fixing bolts 49 are inserted into the reversing disc 47. One end of the tea-conveying hopper 41 is fixedly connected to one end of the vibrating screen body 21, and the connecting sleeve 46 is fitted onto it. The fixing bolt 49 is external to and slidably connected to the connecting column 44. One end of the fixing bolt 49 passes through the insertion hole 48 and extends into the threaded hole 43. The fixing bolt 49 and the threaded hole 43 are connected by threads. When adjusting the conveying direction: if it is necessary to change the conveying direction of the tea reversing conveyor 45, loosen the fixing bolt 49 so that one end is disengaged from the threaded hole 43. Rotate the tea reversing conveyor 45. The connecting sleeve 46 slides outside the connecting column 44. Adjust to the required conveying direction. Pass one end of the fixing bolt 49 through the insertion hole 48 and screw it into the threaded hole 43. Tighten the fixing bolt to fix the direction of the tea reversing conveyor 45.

[0031] The usage process of this utility model is as follows: When using this utility model, connect to an external power source. The electric push rod 31 is preferably an electric push rod with worm gear drive, so that it has a self-locking ability. Through the reverse drive self-locking characteristic of the worm gear, it can stop when the push rod supports the heavy object and rises in vertical load. It can prevent the push rod from retracting due to gravity through mechanical structure, and vice versa.

[0032] When adjusting the screening angle: Start the electric push rod 31. The output end of the electric push rod drives the connecting frame 32 and the connecting plate 33 to slide longitudinally on the inner wall of the left support 12. Since the connecting shaft 22 is connected to the right support 13 through the bearing, the movable shaft 23 slides in the groove inside the connecting plate 33. As the connecting plate 33 rises and falls, the vibrating screen body 21 and the vibrating screen plate rotate around the connecting shaft 22 to adjust the tilt angle. After adjusting to the appropriate angle, the self-locking characteristic of the worm gear of the electric push rod 31 is used to lock the angle of the vibrating screen body 21 and the vibrating screen plate to prevent the angle from changing due to the weight of the tea leaves.

[0033] When adjusting the conveying direction: If it is necessary to change the conveying direction of the tea reversing conveyor 45, loosen the fixing bolt 49 so that one end of it is disengaged from the threaded hole 43, rotate the tea reversing conveyor 45, and the connecting sleeve 46 slides outside the connecting column 44 to adjust to the required conveying direction. Then, insert one end of the fixing bolt 49 through the insertion hole 48 and screw it into the threaded hole 43, tighten the fixing bolt, and fix the direction of the tea reversing conveyor 45.

[0034] During tea sieving and conveying: Place the tea to be sieved on the vibrating screen body 21, turn on the vibrator in the vibrating screen body 21, and under the action of vibration, the tea is sieved on the vibrating screen body 21 and conveyed to the bottom. The tea is sieved on the vibrating screen body 21, and tea of ​​different sizes and shapes falls into the tea vibrating conveying hopper 14 below through the screen holes. The tea that is not sieved enters the tea reversing conveying hopper 45 through the tea conveying hopper 41 and is conveyed to the designated position according to the set conveying direction.
