[0002] Before fresh tea is processed, generally, it is necessary to first screen and grade a large amount of mixed tea, and then carry out the processing work of tea, so as to facilitate the subsequent work of selling tea by quality. When screening tea, a tea screening machine is required. In the existing market when screening tea, either the tea is subjected to air separation and grading by an air separator, or the tea is directly poured above a screening mesh plate, and the screening mesh plate is controlled to vibrate by an external vibration mechanism to complete the tea screening work. However, when performing air separation screening, due to the small weight difference between different grades of tea, it often leads to incomplete air separation during air separation, and subsequent multiple air separation operations are required to complete the thorough grading work. And directly vibrating and screening through the screening plate is prone to a large amount of tea sticking above the screening plate, and continuous tea stirring work is required to complete the screening work. As a result, the entire screening work not only takes a long time, but also requires frequent observation and interference by staff, and the workload is too large. Content of the Utility Model

Detailed Embodiment

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0026] Please refer to Figures 1-6 , the present invention provides a technical solution: a tea grading and screening machine, including a fixed outer shell 1, which is arranged in a rectangular hollow structure, and a feed inlet 3 penetrating through it is arranged at its top, and a cover plate 2 is bolted to the outside of the fixed outer shell 1;

[0027] It also includes;

[0028] The screening mechanism 9 is symmetrically arranged in the fixed outer shell 1 in two, and its top on one side is arranged in the mounting seat 4 through the vibration mounting mechanism 10, and the mounting seat 4 penetrates through the inside of the fixed outer shell 1;

[0029] The air blowing mechanism is arranged in the middle above the screening mechanism 9 and is used for air blowing work to achieve the effect of air separation of tea leaves;

[0030] This application provides a tea grading and screening machine with both a vibration mounting mechanism 10 and an air blowing mechanism. Specifically, when working, first pour the tea leaves into the entire fixed outer shell 1 through the feed opening 3. After that, the tea leaves will fall above the top screening mechanism 9. Then, the air blowing mechanism and the vibration mounting mechanism 10 can be started simultaneously. The air blowing mechanism performs air blowing work to initially perform air separation on the falling tea leaves. For the tea leaves that fall on the screening mechanism 9, since the vibration mounting mechanism 10 is arranged at the top of the screening mechanism 9, it will drive the vibration mounting mechanism 10 to continuously vibrate the tea leaves. Thus, during the vibration, the effect of sorting the tea leaves is completed. When the sorting of the tea leaves inside the entire fixed outer shell 1 is completed, at this time, the cover plate 2 can be opened, and then the screening mechanism 9 can be disassembled above the vibration mounting mechanism 10 to achieve the effect of uniformly collecting the tea leaves piled up on the screening mechanism 9.

[0031] Among them, as shown in Figure 3 , the cross-section of the mounting seat 4 is arranged in a "U" shape, and its three inner sides are connected to the vibration mounting mechanism 10 through the compression spring 11, and the top of the vibration mounting mechanism 10 is engaged with one side of the screening mechanism 9, and the outside of the vibration mounting mechanism 10 is driven to vibrate by the driving motor 5;

[0032] Specifically, when the vibration mounting mechanism 10 works, it is first necessary to start the drive motor 5, so that it drives the vibration mounting mechanism 10 at its top to vibrate inside the mounting seat 4, and then drives the screening mechanism 9 engaged at its top to vibrate.

[0033] Specifically, according to Figures 1-3 As shown, the air blowing mechanism includes a blower 6, an air duct 7 and an air outlet 8. The blower 6 is arranged outside the fixed housing 1, and the air duct 7 and the air outlet 8 are connected to the top of the blower 6. The air outlet 8 is arranged at the middle position above the screening mechanism 9.

[0034] The position of the air outlet 8 is fixed by the limiting plate 12, and the two top ends of the limiting plate 12 are fixed on the front and rear inner walls of the fixed housing 1;

[0035] Specifically, when performing air separation, first, it is necessary to start the blower 6 so that it blows air from the air outlet 8 through the air duct 7. Since the air outlet 8 is arranged at the middle position above the screening mechanism 9, it will perform air separation on the falling tea leaves.

[0036] Furthermore, according to Figure 3 and Figure 5 As shown, the screening mechanism 9 includes an inclined screening plate 91 and a mounting plate 92. The mounting plate 92 is integrally installed at the top of the inclined screening plate 91. The mounting plate 92 is used for engaging with the vibration mounting mechanism 10. The distance between the top of the inclined screening plate 91 and the inner wall of the other side of the fixed housing 1 is greater than 10 CM, which is used for the falling of the tea leaves after air separation. The bottom of the feed inlet 3 is located above the right side of the inclined screening plate 91.

[0037] First, the falling tea leaves will fall above the inclined screening plate 91 and be vibrated and screened. The tea leaves that have been air-separated by the air blown out from the air outlet 8 will fall through the gap between the top of the inclined screening plate 91 and the fixed housing 1 to achieve the effect of air separation. Since the length of the inclined screening plate 91 on the upper screening mechanism 9 is greater than the length of the inclined screening plate 91 on the lower screening mechanism 9, the tea leaves after air separation above will fall onto the inclined screening plate 91 of the lower screening mechanism 9 and be screened again.

[0038] In this application, according to Figures 4-5 As shown, the vibration mounting mechanism 10 includes a fixed frame 101, a rotating shaft 102, a rotating cam 103 and a mounting groove 104. Three sides of the outside of the fixed frame 101 are connected to the inside of the mounting seat 4 through compression springs 11, and a mounting groove 104 is fixed on the outer wall of the other side of the fixed frame 101 for engaging with the top of the mounting plate 92;

[0039] The internal bearing of the fixed frame 101 is connected to the rotating shaft 102, and the rotating cam 103 is coaxially connected to the middle position outside the rotating shaft 102. One side top end of the rotating shaft 102 penetrates through the outer wall of the fixed frame 101 and is connected to the output end of the driving motor 5;

[0040] The installation groove 104 is arranged to penetrate through from front to back;

[0041] Specifically, when the driving motor 5 starts, its top end will drive the rotating shaft 102 to rotate. When the rotating shaft 102 rotates, it will drive the rotating cam 103 to rotate and squeeze inside the fixed frame 101. As a result, the fixed frame 101 will shake inside the mounting seat 4 under the action of the compression spring 11. Since the top end of the installation groove 104 at the top of the fixed frame 101 is engaged with the top end of the inclined screening plate 91, when the fixed frame 101 shakes, it will drive the inclined screening plate 91 to vibrate, thus completing the screening work of the tea. The content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0042] Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
