[0023] 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 making creative efforts shall fall within the protection scope of the present invention.
[0024] Embodiment: As Figures 1-5 shown, the present invention provides a multifunctional tea screening device, including a base 1. A motor 2 is fixedly installed in the middle of the upper surface of the base 1. The output end of the motor 2 is connected to a crank rocker 4. The upper end of the crank rocker 4 is rotatably connected to a heating box 6. Support rods 3 are fixedly installed on the upper surface of the base 1 on both the left and right sides of the motor 2. The top ends of the support rods 3 are rotatably connected to a rotating ring 5. Both the front and rear sides of the heating box 6 extend out a rotating rod 14, and the rotating rod 14 is rotatably connected to the front and rear sides of the rotating ring 5.
[0025] By adopting the above technical solution, through the cooperation of the crank rocker 4 and the rotating ring 5, the rotation output by the motor 2 can be converted into a deflection angle movement at a certain angle, the movement is more stable and provides a certain centrifugal force, and the tea can be screened more fully.
[0026] A screening cage 7 is fixedly installed at the upper end of the heating box 6. A plurality of curved sieve plates 9 are uniformly arranged in the screening cage 7 from top to bottom. The curved sieve plate 9 is conical and its volume gradually decreases from top to bottom.
[0027] A plurality of sieve holes 10 are uniformly penetrated through the conical surface of the curved sieve plate 9, and the diameter of the sieve holes 10 decreases successively with the height of the curved sieve plate 9 in the screening cage 7.
[0028] By adopting the above technical solution, a plurality of curved sieve plates 9 screen tea leaves of different sizes in multiple layers from top to bottom.
[0029] A heat transfer body 12 is arranged at the central position of the curved sieve plate 9. The heat transfer body 12 is a hollow cylinder, and vertical heat release gaps 13 are uniformly opened on the cylindrical surface of the heat transfer body 12, and the heat release gaps 13 are covered with an intercepting net.
[0030] By adopting the above technical solution, the heat transfer body 12 penetrates through the center of the entire inside of the screening cage 7, bringing heat into each layer of the curved sieve plate 9. At the same time, an interception net is installed in the heat release gap 13 to prevent it from falling into the heating box 6 from the heat transfer body 12.
[0031] The lower end of the heat transfer body 12 is clamped with the upper end of the heat transfer body 12 of the next layer, and the top end of the topmost heat transfer body 12 is sealed. The heat transfer body 12 of the lowermost layer is fixedly connected to the lower surface of the screening cage 7.
[0032] A number of circular fixed grooves 11 are uniformly arranged along the horizontal direction on the inner wall of the screening cage 7, and the fixed grooves 11 are clamped with the curved sieve plate 9.
[0033] By adopting the above technical solution, the middle parts of each layer of the curved sieve plates 9 are connected by the heat transfer body 12, and the periphery is fixed by the fixed grooves 11 to prevent loosening.
[0034] An electric heat source 15 is fixedly installed inside the heating box 6.
[0035] A cage cover 8 is threadedly connected to the outside of the opening of the screening cage 7.
[0036] By adopting the above technical solution, the central part of the cage cover 8 is in contact with the top end of the topmost heat transfer body 12, further fixing each layer of the curved sieve plates 9.
[0037] Working principle: When the present utility model is in use, the staff rotates the cage cover 8 to open the screening cage 7, then places the tea leaves to be screened on the topmost curved sieve plate 9, then closes the cage cover 8 and turns on the motor 2. The motor 2 rotates to drive the crank rocker 4, and the heating box 6 at the upper end of the crank rocker 4 rotates accordingly. At the same time, the front and rear sides of the heating box 6 act with the rotating ring 5 and can only rotate in the left and right directions. The left and right sides of the rotating ring 5 are rotatably connected to the support rods 3 and can only rotate in the front and rear directions. The superposition of the two makes the heating box 6 perform a deflection angle movement at a certain angle. Furthermore, the screening cage 7 at the upper end of the heating box 6 also performs a deflection angle movement together. The tea leaves in the screening cage 7 are evenly turned over on the topmost curved sieve plate 9. The larger tea leaves remain on the topmost layer, and the slightly smaller tea leaves fall through the sieve holes 10 into the next layer of the curved sieve plate 9. Repeat the above process until after a certain period of time, tea leaves of various sizes remain on each layer of the curved sieve plates 9. At the same time, the electric heat source 15 in the heating box 6 transfers heat into each layer of the curved sieve plates 9 through the heat transfer body 12 that penetrates through the center of the screening cage 7, preventing the tea leaves from becoming cold and brittle due to too low temperature, thereby affecting the quality of the tea leaves. After the screening is completed, the staff opens the screening cage 7 and takes out the tea leaves on each layer of the curved sieve plates 9 in turn.
[0038] Obviously, those skilled in the art can make various modifications and variations to the present utility model without departing from the spirit and scope of the present utility model. Thus, if these modifications and variations of the present utility model fall within the scope of the claims of the present utility model and their equivalent technologies, the present utility model also intends to include these modifications and variations.
