[0030] Example:

[0031] See also Figure 1 - Figure 4 , a tea roasting machine with screening function, comprising a drying machine box 1, a fan 2 and a heating device 3, the fan 2 is fixedly connected to the top of the drying machine box 1, the heating device 3 is fixedly connected to the top surface of the inner wall of the drying machine box 1, a filter plate 4 is arranged inside the drying machine box 1, a plurality of filter holes 401 are penetrated through the top of the filter plate 4, and the plurality of filter holes 401 are distributed in a rectangular array on the filter plate 4, a plurality of rotating rods 5 are rotatably connected to the inside of the filter plate 4, the number of the plurality of rotating rods 5 is the same as the number of rows of the plurality of filter holes 401, the outside of the plurality of rotating rods 5 are fixedly connected to a plurality of elliptical sheets 6, the number of the plurality of elliptical sheets 6 is the same as the number of the plurality of filter holes 401, and the plurality of elliptical sheets 6 are respectively arranged inside the plurality of filter holes 401;

[0032] A sliding plate 10 is provided inside the drying machine box 1, and gears 7 are fixedly connected to both ends of the plurality of rotating rods 5, racks 8 are slidably connected to both sides of the filter plate 4, the racks 8 are meshed with the gears 7, and two electric push rods 9 are fixedly connected to the top of the sliding plate 10, and the telescopic ends of the two electric push rods 9 are fixedly connected to one end of the two racks 8 respectively.

[0033] Specifically, two sliding frames 11 are fixedly connected to both sides of the inner wall of the drying cabinet 1 , and the four sliding frames 11 are respectively arranged at the four corners of the bottom surface of the sliding plate 10 , and the sliding plate 10 is slidably connected to the four sliding frames 11 .

[0034] Specifically, a material drop groove 1001 is formed through the top surface of the sliding plate 10, and the filter plate 4 is arranged above the material drop groove 1001. The bottom surface of the inner wall of the drying cabinet 1 is slidably connected with a material receiving box 16, and the material receiving box 16 is slidably connected to the fixed frame 101.

[0035] In the present scheme, the fan 2 is used to transmit wind force to the interior of the drying box 1, and the heating device 3 is used to heat the wind force transmitted by the fan 2, so as to form hot wind inside the drying box 1. The filter plate 4 can remain relatively fixed with the sliding plate 10 during the drying operation, and can be removed from the top surface of the sliding plate 10 after the drying operation is completed. The electric push rod 9 is used to push the rack 8 to slide on both sides of the filter plate 4. When the rack 8 slides, the rotating rod 5 can drive the elliptical piece 6 to rotate inside the filter hole 401 through the gear 7. The maximum diameter of the elliptical piece 6 is smaller than the inner diameter of the filter hole 401. After the elliptical piece 6 rotates, the debris blocked in the filter hole 401 will be stirred by rotation, thereby clearing the filter hole 401, which can effectively prevent the filter hole 401 from being blocked by the screened debris all the time, thereby improving the screening efficiency of the device. The debris falling from the filter hole 401 will eventually fall into the material receiving box 16, and the staff needs to take out the material receiving box 16 regularly and pour out the debris inside it for cleaning.

[0036] See also Figure 1 - Figure 3 A motor 12 is fixedly connected to one side of the drying box 1, and a transmission shaft 13 is transmission-connected to the output end of the motor 12. One end of the transmission shaft 13 passes through one side of the drying box 1 and is rotationally connected to one side of the inner wall of the drying box 1.

[0037] Specifically, both ends of the transmission shaft 13 are fixedly connected with a rotating plate 14 , and one side of the two rotating plates 14 close to the sliding plate 10 is fixedly connected with an eccentric block 15 .

[0038] Specifically, a fixed frame 101 is fixedly connected to the bottom surface of the inner wall of the drying box 1 , one rotating plate 14 is rotatably connected to one side of the inner wall of the drying box 1 , and the other rotating plate 14 is rotatably connected to one side of the fixed frame 101 .

[0039] Specifically, the bottom surface of the sliding plate 10 and the portions close to the edges on both sides are fixedly connected to the limiting frames 1002 , and the eccentric block 15 is slidably connected inside the limiting frames 1002 .

[0040] In this solution, the motor 12 rotates the rotating plate 14 through the transmission shaft 13, and the eccentric block 15 is at a certain distance from the center of the rotating plate 14. When the rotating plate 14 rotates, the eccentric block 15 will slide up and down in the limit frame 1002, and apply a thrust in the left and right directions to the limit frame 1002, so that the sliding plate 10 slides inside the sliding frame 11 through the limit frame 1002. The sliding plate 10 is in a state of reciprocating sliding left and right inside the drying machine box 1. When the sliding plate 10 slides back and forth, it will drive the filter plate 4 to move together, so that the filter plate 4 vibrates, and the tea leaves on the top surface of the filter plate 4 are screened, thereby improving the screening efficiency of the device.

[0041] Working principle: When performing the baking operation, the staff first places the tea leaves on the top surface of the filter plate 4, and then turns on the fan 2 and the heating device 3 to bake the tea leaves. When the baked tea leaves need to be screened, the staff can turn on the motor 12, thereby driving the rotating plate 14 to rotate through the transmission shaft 13, and then the eccentric block 15 on the rotating plate 14 drives the limit frame 1002 to slide back and forth left and right, so that the filter plate 4 is in a vibrating state, thereby achieving the screening of the tea leaves;

[0042] If the filter hole 401 is clogged with debris during the tea screening process, the staff can turn on the electric push rod 9, which pushes the rack 8 to slide, and makes the gear 7 meshing with the rack 8 drive the rotating rod 5 to rotate, so that the elliptical piece 6 rotates inside the filter hole 401. After the elliptical piece 6 rotates, it will stir the debris clogged in the filter hole 401 through rotation, thereby unblocking the filter hole 401, which can effectively prevent the filter hole 401 from being clogged by the screened debris, thereby improving the screening efficiency of the device. The debris falling from the filter hole 401 will eventually fall into the material receiving box 16, and the staff needs to take out the material receiving box 16 regularly and pour out the debris inside to clean it.

[0043] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
