[0002] With the improvement of people's living standards, the proportion of people who drink tea daily is getting higher and higher. Therefore, the scale of tea planting and tea making is also getting larger and larger. When producing tea in autumn, it is necessary to screen the size and debris of tea. The existing screening devices for tea generally achieve the screening of tea through blowing or vibrating sieves. For example, an automatic tea screening device disclosed in CN111774284A includes a base, a baffle, an inclined plate, a driving mechanism and a vibrating mechanism. The vibrating mechanism includes a bottom plate, a vibrating component and a restoring component. The driving mechanism includes a motor, a driving shaft, a support rod and a semi-circle. This automatic tea screening device realizes the screening of tea through the driving mechanism and the screening mechanism. Here, when the semi-circle abuts against the abutting plate, the third spring will be stretched, so that while the abutting plate moves on the moving block, the bottom plate also moves. And when the semi-circle fits with the abutting plate, the up and down movement of the moving block is realized. Here, the multi-directional movement of the moving block is realized through the same driving source, and the micro-vibration of the moving block is realized through the restoring force of the spring, that is, the micro-vibration of the inclined plate and the screening net is realized, so as to realize the screening of tea.

The front side and the rear side of the hard tea screen 4 are respectively in movable contact with the front inner wall and the rear inner wall of the box body 1. Guide plates 5 inclinedly arranged are fixedly connected to both sides of the box body 1. The guide plates 5 cooperate with the corresponding discharge holes 3. By using the vibration of the vibration motors 2 to drive the box body 1 and the two hard tea screens 4 to vibrate at high frequency and slightly, the tea is filtered into three specifications of size and residue by the vibration of the two hard tea screens 4 and is automatically discharged by its inclined form.

[0025] Specifically, the elastic support component includes fixing plates 8. The closer sides of the two fixing plates 8 are respectively fixedly connected to both sides of the box body 1. A flexible rubber block 9 is adhesively fixed to the bottom of the fixing plate 8. An L-shaped plate 10 is adhesively fixed to the bottom of the flexible rubber block 9. Two vertical guide rods 11 are fixedly connected to both sides of the top of the bottom plate 7. The L-shaped plate 10 is slidably sleeved on the corresponding two vertical guide rods 11.

The provided electric push rod 13, L-shaped moving plate 14, and second connecting rod 15 cooperate. The electric push rod 13 is used to drive the L-shaped moving plate 14 to move upward. The L-shaped moving plate 14 drives the second connecting rod 15 to squeeze and drive the lower rigid tea sieve 4 to rotate upward. The lower rigid tea sieve 4 drives the first connecting rod 6 to squeeze and drive the upper rigid tea sieve 4 to rotate upward, achieving the effect of synchronously driving the two rigid tea sieves 4 to rotate and adjust the inclination. The inclination is adjusted to adjust the vibration discharge efficiency of the tea on the inclined plane.

[0027] The usage method of this embodiment is as follows: Start the two vibration motors 2 to drive the box body 1 to vibrate integrally. When the box body 1 vibrates vertically, it can drive the two fixing plates 8 to vibrate vertically. The fixing plates 8 drive the L-shaped plates 10 to slide vertically on the vertical guide rods 11 through the corresponding flexible rubber blocks 9, and compress or release the springs 12. When the box body 1 vibrates horizontally, it drives the two fixing plates 8 to push and pull the two flexible rubber blocks 9 to deform. The elastic force of the flexible rubber blocks 9 and the springs 12 is used to achieve the effect of elastically supporting the box body 1, and the elastic support does not affect the normal vibration of the box body 1. Pour the tea into the box body 1. The tea first falls on the upper rigid tea sieve 4. At this time, the upper rigid tea sieve 4 vibrates and screens the tea during vibration. Since the filter holes of the upper rigid tea sieve 4 are larger than those of the lower rigid tea sieve 4, the tea is filtered and blocked on the top of the upper rigid tea sieve 4. The small tea leaves fall on the lower rigid tea sieve 4 and are filtered by its vibration. The crushed residues are discharged downward through the lower rigid tea sieve 4 and collected in the crushed residue collection box 200. At this time, the two inclined and vibrating rigid tea sieves 4 respectively guide and discharge the two specifications of tea leaves outward. The two specifications of tea leaves respectively fall and are collected in the large tea leaf collection box 100 and the small tea leaf collection box 300, achieving the effect of automatically vibrating and screening the size and crushed residues of the tea, and achieving the effect of automatically diverting and discharging and collecting the two specifications of tea leaves and crushed residues after screening. By using the method of screening the size twice, the material separation effect is improved.

[0028] When it is necessary to adjust the discharging efficiency according to different screening requirements, the electric push rod 13 is started in the forward direction to drive the L-shaped moving plate 14 to move upward. The L-shaped moving plate 14 drives the second connecting rod 15 to squeeze and drive the lower hard tea sieve 4 to rotate upward. The lower hard tea sieve 4 drives the first connecting rod 6 to squeeze and drive the upper hard tea sieve 4 to rotate upward. The two hard tea sieves 4 respectively stretch the corresponding elastic shielding rubber sheets 16. At this time, the inclination angles of the two hard tea sieves 4 change, which is convenient for synchronously and quickly adjusting the inclination angles of the two hard tea sieves 4. By adjusting the inclination angles of the hard tea sieves 4, the vibration discharging efficiency can be adjusted. By means of adjustable inclination discharging efficiency, the use flexibility is improved.
