[0028] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0029] Reference Figure 1-3A vibration screening machine for tea processing includes a screening machine shell 1. The operation mode of the screening machine shell 1 is to move the material on the screen by vibration, thereby completing the material screening process. A buffer structure 2 is arranged on the top of the screening machine shell 1. The buffer structure 2 includes a material discharge box 201 installed on the top wall of the screening machine shell 1. The discharge port of the material discharge box 201 is located above the screening machine shell 1. A first connecting member 204 is installed on the inner wall of the material discharge box 201. A first rotating plate 203 is hinged on the inner wall of the material discharge box 201. The first rotating plate 203 is located directly above the first connecting member 204. The first rotating plate 203 is close to the feeding port of the material discharge box 201.

[0030] The inner wall of the first connecting member 204 is movably connected with the first electric telescopic rod 205, and the second connecting member 206 is installed on the side of the first rotating plate 203 away from the discharge box 201. The surface material of the second connecting member 206 is rubber material, which effectively avoids damage caused by impact during the falling process of tea leaves. The inner wall of the second connecting member 206 is movably connected with the telescopic end of the first electric telescopic rod 205, and the tea leaves are poured from the feeding port at the top of the discharge box 201. By starting the first electric telescopic rod 205, the telescopic end of the first electric telescopic rod 205 drives the first rotating plate 203 to move upward to adjust the angle of the first rotating plate 203, so as to slow down the falling speed of the tea leaves.

[0031] A second rotating plate 207 is hingedly connected to a side of the unloading box 201 away from the first rotating plate 203. The surface material of the second rotating plate 207 is rubber material, which effectively avoids damage caused by impact during the falling process of tea leaves. A third connecting member 208 is installed on a side of the unloading box 201 adjacent to the second rotating plate 207. The third connecting member 208 is located directly below the second rotating plate 207. The second rotating plate 207 is located directly below the first rotating plate 203. The inner wall of the third connecting member 208 is movably connected with a second electric telescopic rod 209. A fourth connecting member 210 is installed on a side of the second rotating plate 207 away from the unloading box 201. The inner wall of the fourth connecting member 210 is movably connected to the telescopic end of the second electric telescopic rod 209. When the tea leaves on the first rotating plate 203 fall on the second rotating plate 207, the second electric telescopic rod 209 is started, and the telescopic end of the second electric telescopic rod 209 drives the second rotating plate 207 to move. By adjusting the angle of the second rotating plate 207, the problem of damage to the tea leaves caused by rapid falling of the tea leaves is further avoided.

[0032] Reference Figure 2-3The bottom wall of the discharge box 201 is provided with a discharge pipe 7, the inner wall of the discharge pipe 7 is connected to the discharge port of the discharge box 201, the shape of the second rotating plate 207 has a certain slope, and the inclined discharge pipe 7 further slows down the speed of the tea leaves falling. The top wall of the discharge box 201 is connected with the discharge box 202, the inner wall of the discharge box 202 is made of rubber material, and the bottom wall of the discharge box 202 is provided with a slot 4, and the slot 4 provided in the bottom wall of the discharge box 202 is provided with a plug plate 5. By inserting the plug plate 5 into the slot 4 provided in the discharge box 202, the discharge port of the discharge box 202 can be closed. After pouring tea leaves into the discharge box 202, the time for the tea leaves to fall can be controlled by the plug plate 5. The discharge port of the discharge box 202 is provided with a sliding opening 6, and the sliding opening 6 provided in the discharge box 202 is located above the plug plate 5. The discharge box 202 has a certain curvature, which is convenient for the tea leaves to slide down.

[0033] Reference Figure 1 and Figure 4 A reinforcement structure 3 is provided on the screening machine housing 1, and the reinforcement structure 3 includes a first filter screen 301 installed on the inner wall of the screening machine housing 1. The first filter screen 301 is an existing structure inside the screening machine housing 1. A spring 304 is installed on the top wall of the first filter screen 301, and a second filter screen 302 is installed on the top wall of the spring 304. The second filter screen 302 is located below the discharge pipe 7. The outer wall of the second filter screen 302 is slidably connected to the inner wall of the screening machine housing 1. A plurality of springs 304 are symmetrically and equidistantly distributed around the second filter screen 302, and the surface material of the second filter screen 302 is rubber material, which effectively prevents the collision between the tea leaves and the second filter screen 302 during the operation of the screening machine housing 1, resulting in damage to the tea leaves and affecting the quality of the tea leaves.

[0034] The top wall of the first filter 301 is installed with a telescope 303, and the top wall of the telescope 303 is fixedly connected to the bottom wall of the second filter 302. The telescope 303 is located inside the spring 304, and the number of the telescopes 303 is the same as the number of the springs 304. The telescope 303 is set to provide a certain support to the second filter 302 and to limit the spring 304, thereby effectively avoiding the possibility of damage to the telescope 303.

[0035] Working principle:

[0036] After pouring the tea leaves into the discharge box 202 and pulling out the plug plate 5, the tea leaves fall onto the first rotating plate 203. By starting the first electric telescopic rod 205, the output end of the first electric telescopic rod 205 drives the first rotating plate 203 to move, and moves the first rotating plate 203 to a suitable angle to slow down the falling speed of the tea leaves. At this time, the tea leaves fall onto the second rotating plate 207, and then the second electric telescopic rod 209 is started. The output end of the second electric telescopic rod 209 drives the second rotating plate 207 to move to the discharge port position of the discharge box 201. The tea leaves slowly flow to the screening machine housing 1 through the second rotating plate 207. By controlling the falling speed of the tea leaves, the problem of the tea leaves being broken or crushed due to excessive friction, collision or squeezing when passing through can be effectively avoided, thereby effectively improving the taste and appearance of the tea leaves.

[0037] After the tea leaves fall onto the second filter screen 302 through the discharge port of the discharge box 201, the operation of the screening machine housing 1 drives the telescopic device 303 and the spring 304 to achieve a contraction effect, and drives the second filter screen 302 to shake up and down, effectively avoiding the problem of weakened tea leaf screening effect due to material problems of the second filter screen 302.

[0038] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
