[0022] To make the technical means, creative features, objectives, and effects of this utility model easier to understand, the following describes this utility model in conjunction with specific embodiments:

[0023] like Figure 1 As shown, this utility model provides a tea drying device, including a shell 1, a flattening module 2 installed inside the shell 1, and a screening module 3 installed below the flattening module 2. During the tea drying operation, the tea leaves are placed in the flattening module 2 for heating, and after heating, the flattening module 2 pushes them to the screening module 3 for screening.

[0024] like Figure 2 As shown, this utility model provides a technical solution: the flattening module 2 includes a support 22, the right side of which is fixedly connected to the housing 1. A motor 21 is fixedly connected above the support 22. The output shaft of the motor 21 passes through the housing 1 and is fixedly connected to a baffle 224. The baffle 224 is rotatably connected to the housing 1. Two triangular ribs 23 are fixedly installed below the support 22. The right sides of the two triangular ribs 23 are fixedly connected to the housing 1. A fixing seat 24 is fixedly connected to the housing 1 in front of the triangular ribs 23. A lead screw 28 and a lead screw 25 are rotatably connected to the front of the fixing seat 24. The lead screw 25 is located above the lead screw 28. The other ends of the lead screw 25 and the lead screw 28 pass through the fixing seat 29 and are rotatably connected to it. A triangular rib 212 is fixedly connected to the front of the fixing seat 29. A support is fixedly connected above the triangular rib 212. Frame 213 has motor 3 211 and motor 2 210 fixedly connected inside. The output shaft of motor 2 210 is fixedly connected to lead screw 1 25, and the output shaft of motor 3 211 is fixedly connected to lead screw 2 28. Triangular rib 3 215 is fixedly connected to the right side of triangular rib 2 212 in housing 1. Frame 3 216 is fixedly connected above triangular rib 3 215. Motor 4 217 is fixedly connected above bracket 3 216. Heating platform 214 is fixedly connected inside housing 1. Triangular ribs are installed below the frame to prevent the frame from bending due to insufficient rigidity during motor operation, which would cause the motor to fail to transmit power normally. When drying is finished, motor 1 21 drives baffle 224 to rotate, creating a gap between the rear of heating platform 214 and baffle 224. At this time, pushing the tea leaves will cause them to fall to the lower layer. Lead screw 2 28 and lead screw 1 25 are driven by motor 3 211 and motor 2 210, respectively.

[0025] like Figure 3As shown, this utility model provides a technical solution: the output shaft of motor 4 217 is fixedly connected to lead screw 3 220, lead screw 3 220 passes through bracket 3 216 and is rotatably connected to it, the end of lead screw 3 220 away from bracket 3 216 is rotatably connected to fixed seat 3 222, the outer wall of lead screw 3 220 is threadedly connected to slider nut 3 218, the left side of slider nut 3 218 is fixedly connected to push plate 1 219, and the outer wall of lead screw 1 25 is threadedly connected to slider nut 2 2 6. A push plate 221 is fixedly connected to the right side of slider nut 26. Screw 28 is threadedly connected to slider nut 27. Trapezoidal block 223 is fixedly connected to the right side of slider nut 27. Trapezoidal block 223, push plate 221, and push plate 219 are all above and slidably connected to heating platform 214. Push plate 221 is located between trapezoidal block 223 and push plate 219, and push plate 219 is located in front of trapezoidal block 223. During tea drying, the screw... Motor 28 drives slider nut 27 to move, which in turn drives trapezoidal block 223 to slide above heating platform 214 and scoop up tea leaves from the bottom of heating platform 214, preventing them from sticking. Push plate 221 is driven by lead screw 25 and slider nut 26 in the same way. The bottom of push plate 221 is slightly higher than heating platform 214, so when push plate 221 slides above heating platform 214, it pushes the higher-piled tea leaves to a distance, preventing them from piling up and achieving the effect of leveling the tea leaves. When drying is finished, motor 21 drives baffle 224 to rotate, creating a gap between baffle 224 and heating platform 214. Motor 4 217 drives lead screw 3 220, which slides above heating platform 214 via slider nut 3 218. The bottom of lead screw 3 220 contacts heating platform 214, and pushing lead screw 3 220 pushes the tea leaves into the gap between baffle 224 and heating platform 214.

[0026] like Figure 4 As shown, this utility model provides a technical solution: the screening module 3 includes a motor 31, a special-shaped push rod 33, and two fixed seats 34. The output shaft of the motor 31 is fixedly connected to an eccentric wheel 32. The center of the special-shaped push rod 33 has a short groove and is slidably connected to the eccentric wheel 32. A locking block 35 is rotatably connected to the front of the fixed seat 34. A screen frame 36 is slidably connected inside the fixed seat 34. The motor 31 drives the eccentric wheel 32 to rotate, and the eccentric wheel 32 drives the special-shaped push rod 33 to reciprocate. The fixed seat 34 locks the screen frame 36 so that it moves with the fixed seat 34. When the screen frame 36 needs to be removed, the locking block 35 can be moved to pull out the screen frame 36.

[0027] like Figure 5As shown, this utility model provides a technical solution: a bracket 37 is fixedly connected to the lower part of the motor 31, and two triangular ribs 38 are fixedly connected to the lower part of the bracket 37. Both the triangular ribs 38 and the bracket 37 are fixedly connected to the left side of the housing 1. Several limiting blocks 39 are fixedly connected to the upper and lower sides of the irregular push rod 33 on the housing 1. A sliding groove is opened on the left side of the housing 1. Two connecting rods are installed on the left side of the fixing seat 34. The connecting rod on the left side of the fixing seat 34 passes through the sliding groove of the housing 1 and is slidably connected to it. The connecting rod of the fixing seat 34 is slidably connected to the long sliding grooves on both sides of the irregular push rod 33. The limiting blocks 39 restrict the irregular push rod 33 to move only back and forth. When the irregular push rod 33 moves, it pushes the fixing seat 34 to move along the sliding groove opened on the housing 1.

[0028] like Figure 6 As shown, this utility model provides a technical solution: an extension plate 310 is fixedly connected to the shell 1 below the screen frame 36, a receiving box 311 is slidably connected to the shell 1 below the extension plate 310, a slide rail 313 is fixedly connected to the shell 1 below the fixed seat 34, a receiving box 312 is slidably connected to the bottom of the shell 1, and the slide rail 313 supports the fixed seat 34. After screening, the tea leaves fall into the receiving box 311 through the extension plate 310, and the tea leaves and dust fall into the receiving box 312.

[0029] The working principle of this tea drying device will be explained in detail below.

[0030] like Figure 1-6As shown, when drying tea leaves, an appropriate amount of tea leaves is placed on the heating platform 214. The heating platform 214 begins to heat. At this time, the tea leaves are stacked. The motor 210 drives the lead screw 25 to rotate. The lead screw 25 drives the push plate 221 to slide above the heating platform 214 through the slider nut 26. Because the bottom of the push plate 221 is slightly higher than the upper surface of the heating platform 214, the push plate 221 will push the higher stack of tea leaves to a distance when it moves, achieving the effect of flattening the tea leaves. After the push plate 221 moves... Motor 3 211 starts driving lead screw 28 to rotate. Lead screw 28 drives trapezoidal block 223 to move via slider nut 27. The bottom of trapezoidal block 223 is in contact with the upper surface of heating platform 214, so when trapezoidal block 223 moves, it will scoop up the tea leaves at the bottom to prevent them from sticking to the top of heating platform 214. After trapezoidal block 223 moves, push plate 221 moves to flatten the tea leaves. After drying, motor 1 21 drives baffle 224 to rotate. At this time, a gap is formed between baffle 224 and heating platform 214, and then... Motor 4 217 drives lead screw 3 220 to rotate. Lead screw 3 220 drives push plate 1 219 to slide above heating platform 214 via slider nut 3 218. The bottom of push plate 1 219 is in contact with the upper surface of heating platform 214. When heating platform 214 moves, it pushes tea leaves through the gap between heating platform 214 and baffle 224 to begin tea leaf sorting. Motor 5 31 drives eccentric wheel 32, which drives irregular push rod 33 to reciprocate. Limit block 39 restricts irregular push rod 33 to move only... When the push rod 33 moves back and forth, it pushes the fixed seat 34 to move along the sliding groove opened on the housing 1. The fixed seat 34 locks the screen frame 36 through the locking block 35, thereby driving the screen frame 36 to move synchronously. This allows the screen on the screen frame 36 to move back and forth, thereby improving screening efficiency and preventing material accumulation. The tea leaves screened by the screen frame 36 fall into the receiving box 311 through the extension plate 310, while the tea residue falls into the receiving box 312. When the screen needs to be replaced, the screen frame 36 can be pulled out by opening the locking block 35 to replace the screen.

[0031] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
