Description

Technical Field

[0001] The utility model relates to the technical field of tea screening, in particular to a tea screening device. Background Art

[0002] Tea is commonly known as tea, generally including the leaves and buds of tea trees. Its aliases are tea, jia, ming, and chuan. The components of tea include catechins, cholestenone, caffeine, inositol, folic acid, and pantothenic acid, which are beneficial to health. The tea beverage made from tea is one of the three major beverages in the world. During the tea production and processing process, it is necessary to screen the tea to select thick buds and thin buds.

[0003] A tea screening device described in the patent with the publication number CN220716664U includes a support frame base system, an electromagnetic reciprocating drive system, and a screening frame system. The frame base is movably installed on the frame-shaped base, and an electromagnet and a positioning guide rod connected to the electromagnet are installed on the frame-shaped base. The column rod provided on the positioning guide rod is inserted and installed on the frame base. When screening the tea, the electromagnet at one end of the frame-shaped base works to magnetically attract the frame base, and the frame base moves towards one end of the frame-shaped base. At this time, the electromagnet at this end stops working, and the electromagnet at the other end works, and the frame base moves towards the other end of the frame-shaped base. In this way, the screening of the tea in the screen frame is realized. The thin buds fall from the screen frame, and the thick buds fall out from the discharge port. Compared with the traditional screening device driven by a motor for vibration screening, this device drives the screening frame system to move left and right for screening through magnetic attraction by the electromagnet, with low noise and reduced damage to the operators.

[0004] Although the above-mentioned tea screening device solves certain problems, it still has the following disadvantages:

[0005] (1) When the tea is fed onto the sieve plate, the tea can only be spread out by the movement of the sieve plate, and the tea is prone to agglomeration, affecting the screening efficiency.

[0006] (2) Only the vibration of the sieve mesh can be used to screen the tea for thickness, and tea residues and the like contained in the tea cannot be screened out, which are mixed in the tea with thin buds and affect the quality of the tea. Utility Model Content

[0038] Here, exemplary embodiments will be described in detail, and the examples are shown in the accompanying drawings. When the following description refers to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. On the contrary, they are merely examples of devices consistent with some aspects of the present disclosure as detailed in the appended claims.

[0039] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. 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.

[0040] Embodiment 1:

[0041] As Figures 1 to 5As shown in the figure, this embodiment proposes a tea screening device, which includes a bottom shell 1, a spreading component 2, a feeding inclined plate 3, a slag removal component 4, a sieve plate 5, a transmission component 6, a driving component 7, a conveying table 8, a baffle 12, and a conveyor belt 11 arranged inside the conveying table 8.

[0042] Among them, the bottom shell 1 is a square cylinder with an open front end and an open lower side at the rear end. The lower side at the rear end serves as a slag outlet 13 for discharging tea dregs from the tea. A conveying table 8 is fixedly connected to the upper rear side of the bottom shell 1. Transmission rollers 10 are rotatably connected to the front and rear interiors of the conveying table 8. The rotating shaft of one of the front transmission rollers 10 extends to the outside of the conveying table 8. Side guards 9 are fixedly connected to both upper ends of the outside of the conveying table 8. There is a rotating shaft 201 in the front between the two side guards 9. One end of the rotating shaft 201 also extends out from the inside of the side guard 9 and is flush with the rotating shaft of the extended transmission roller 10. On the two extended rotating shafts, a driving transmission wheel 601 is fixedly connected to the rotating shaft 201, and a driven transmission wheel 602 is fixedly connected to the rotating shaft of the transmission roller 10. A transmission belt 603 connects the driving transmission wheel 601 and the driven transmission wheel 602 together. The rotating shaft 201 is driven to rotate by a first driving motor 203 installed outside the side guard 9 and away from the extended end of the rotating shaft 201. The rotation of the rotating shaft 201 drives the transmission roller 10 to rotate, facilitating the forward transmission of the conveyor belt 11 on the transmission roller 10 and conveying the tea above to the inside of the feeding port 15 opened on the upper side outside the bottom shell 1.

[0043] At the same time, a number of evenly distributed spreading rods 202 are fixedly connected to the rotating shaft 201. Driven by the rotation of the rotating shaft 201, the piled-up tea on the conveyor belt 11 is dispersed to prevent the tea from falling into the inside of the feeding port 15 in a pile, which affects the screening effect. Foot supports 14 are fixedly connected to the four corners of the lower end of the outside of the bottom shell 1 to ensure stability.

[0044] In order to remove dregs from the screened tea, filter plates 401 are fixedly connected to the lower side of the conveying table 8 and the front side of the inner bottom end of the bottom shell 1. The filter plates 401 prevent the tea from falling into the inside of the bottom shell 1, facilitating the suction of the tea dregs into the inside of the bottom shell 1 by the blower 402 behind the filter plates 401. The tea is sequentially de-dregs before entering the feeding port 15 and de-dregs again during discharging after screening is completed, ensuring the quality of the screened tea.

[0045] In order to screen tea leaves, an inclined sieve plate 5 is arranged inside the bottom shell 1. The rear end of the sieve plate 5 is high and the front end is low. The two sides at the rear end of the sieve plate 5 are rotatably connected to the two sides inside the bottom shell 1. When the front end of the sieve plate 5 moves up and down and the front end of the sieve plate 5 moves downward, the lower side of the front end will contact the upper side of the baffle 12 arranged on the front side inside the bottom shell 1, generating vibration for the sieve plate 5 to screen the tea leaves. The relatively plump tea leaves move forward along the sieve plate 5 and are screened out from the front end of the bottom shell 1 through the baffle 12, while the tea leaves with unqualified particles fall out from the sieve holes of the sieve plate 5 and drop onto the feeding inclined plate 3 arranged inside the bottom shell 1. The feeding inclined plate 3 is in an L shape, with the rear end fixedly connected to the outer lower side of the conveying table 8, the front end being below the baffle 12, and both sides being fixedly connected to the two sides inside the bottom shell 1, presenting an overall L shape. The unqualified tea leaves fall out from the sieve holes of the sieve plate 5 and slide out of the front side of the bottom shell 1 from the feeding inclined plate 3.

[0046] Embodiment 2:

[0047] The solution in Embodiment 1 will be further introduced below in combination with the specific working mode. See the following description for details:

[0048] In order to facilitate the up and down movement of the front end of the sieve plate 5, a movable hole 16 is opened at the front side of the upper end of the bottom shell 1, a positioning hole 17 is opened on the upper side of the baffle 12, and a vertically arranged lifting rod 701 is arranged on the front side inside the bottom shell 1. The lifting rod 701 moves up and down inside the movable hole 16, and the positioning hole 17 is used to ensure that the lifting rod 701 can only move up and down. A horizontally arranged linkage slot hole 20 is opened on one side of the lifting rod 701, and a mounting slot hole 18 is opened on the front side of the sieve plate 5. The lifting rod 701 is inside the mounting slot hole 18 and is slidably connected to the inside of the mounting slot hole 18. A linkage rod 19 is arranged inside the mounting slot hole 18, and the linkage rod 19 slides inside the linkage slot hole 20. Since the length of the sieve plate 5 remains unchanged and the rear end is hinged, when the front end moves up and down, the linkage rod 19 will not only move up and down but also have a certain amount of forward and backward displacement. However, the lifting rod 701 can only move up and down, so the linkage rod 19 needs to slide back and forth inside the linkage slot hole 20 to offset the forward and backward displacement.

[0049] Embodiment 3:

[0050] The solution in Embodiment 2 will be further introduced below in combination with the specific working mode. See the following description for details:

[0051] In order to enable the lifting rod 701 to reciprocate up and down automatically, a linkage ring block 702 is fixedly connected to the upper end of the lifting rod 701. A mounting plate 703 is also fixedly connected to the front side of the upper end of the outer bottom shell 1. The mounting plate 703 is on the side of the movable hole 16 close to the first driving motor 203. A turntable 704 is rotatably connected to the side of the mounting plate 703 close to the movable hole 16. A second driving motor 706 for driving the turntable 704 to rotate is fixedly connected to the other side of the mounting plate 703. A toggle post 705 is fixedly connected to the edge of the side of the turntable 704 away from the mounting plate 703. The toggle post 705 is inserted into the inside of the linkage ring block 702. As the turntable 704 rotates, the linkage ring block 702 drives the lifting rod 701 to move up and down, and the front and back displacement of the toggle post 705 as it rotates with the turntable 704 is offset by the front and back sliding of the toggle post 705 inside the linkage ring block 702, causing the lifting rod 701 to reciprocate up and down to drive the front end of the sieve plate 5 to move up and down for tea screening.

[0052] The electrical components appearing in this text are all connected to an external main controller and 220V mains power. The main controller can be a conventional known device such as a computer for control. In the specific implementation of this disclosure, the detailed descriptions of known functions and known components are omitted. To ensure the compatibility of the device, the operating means adopted are consistent with the parameters of market instruments.

[0053] Although the embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
