DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0023] Please refer to Figures 1-4 , in the embodiments proposed in this application: A tea vibration screening and grading device, comprising:

[0024] An installation housing 1, with a feed inlet 2 installed at its upper end, and the lower end of the feed inlet 2 is open. A guiding plate 3 is fixed at the lower end of the feed inlet 2. The guiding plate 3 is inclined, so that the tea to be screened entering from the feed inlet 2 can move downward along the guiding plate 3, avoiding a large amount of tea staying in the guiding plate 3. A guiding block 7 is also provided on the right side of the guiding plate 3. The left side of the guiding block 7 has a smaller inclination degree than its right side, so that when the blower 4 blows up the tea, the number of tea moving to the right can be reduced. A blower 4 is provided on the lower side of the guiding block 7. After blowing, the tea is blown up, which can eliminate the crushing damage of the tea, thereby reducing the damage rate of the tea during the processing process. At the same time, it can disperse the tea, avoiding accumulation during the screening process and affecting the screening quality and efficiency. A filter screen 5 is installed on the upper side of the blower 4 to prevent tea from entering the blower 4. A wind guiding plate 6 is installed on the upper side of the filter screen 5, and the wind guiding plate 6 is inclined, which can increase the gathering effect when the tea enters, and at the same time can guide the wind direction when the blower 4 blows outwards, so that the tea is blown to the outside.

[0025] A multi-stage vibration screening mechanism, which is arranged on the lower side of the blower 4. The multi-stage vibration screening mechanism includes a first screen 9. An installation outer frame 13 is installed outside the first screen 9, and a limiting plate 11 is installed at the lower end of the installation outer frame 13. A cam 12 is installed inside the limiting plate 11. The longitudinal section of the cam 12 is in the shape of a water droplet. The rear end of the cam 12 is connected to the output end of the motor, so that during the rotation of the cam 12, the first screen 9 can be driven to move up and down, enabling the tea dispersed by the blower 4 to be further vibration-screened.

[0026] A first collection tank 17 is arranged on the lower side inside the installation housing 1, and a third collection tank 19 is arranged on the right side of the first screen 9. The first collection tank 17 can receive small impurities such as tea dregs, which is convenient for later use. The third collection tank 19 can receive large and complete tea leaves for high-quality tea processing.

[0027] In another embodiment, a fan 8 is also provided on the right side of the guiding block 7.

[0028] Further, during the blowing process, the fan 8 can further reduce the number of tea leaves to be screened moving to the right, while increasing the dispersion effect on the tea leaves again.

[0029] In another embodiment, an installation rod 16 fixed to the inner wall of the installation housing 1 is further installed inside the installation outer frame 13, and the installation rod 16 is slidably connected to the installation outer frame 13.

[0030] Further, it can limit the left end of the installation outer frame 13 to prevent it from tilting.

[0031] In another embodiment, an upper cover plate 14 is further fixed to the upper end of the installation outer frame 13, and the longitudinal section of the upper cover plate 14 is in an "L" shape.

[0032] Further, it can cover the connection structure between the installation outer frame 13 and the upper cover plate 14 to prevent tea leaves from entering and being damaged.

[0033] In another embodiment, a connecting cover plate 15 is further fixed to the lower end of the installation outer frame 13, and a second sieve 10 is installed at the lower end of the connecting cover plate 15.

[0034] Further, the second sieve 10 is used to increase the screening degree of the tea leaves, so that it can screen the large particle tea dregs that may appear in the tea dregs and increase the further utilization rate.

[0035] In another embodiment, a second collection tank 18 is further arranged on the left side of the second sieve 10.

[0036] Further, it collects the tea dregs screened by the second sieve 10.

[0037] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variation thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device.
