[0014] The specific contents of the utility model are described in detail below with reference to the accompanying drawings and embodiments.

[0015] like Figure 1 , Figure 2 and Figure 3 As shown, the utility model provides a dehydration device for fresh tea production, including a box body 1, a rotatable connecting frame 2 with open top and bottom is provided in the box body 1, a filter screen 21 is fixed in the connecting frame 2, a bearing plate 22 located in the connecting frame 2 is provided below the filter screen 21, a spring 23 is fixed between the filter screen 21 and the bearing plate 22, and a vertical rod 24 penetrating the filter screen 21 is fixed on the bearing plate 22; a motor 4 for driving the connecting frame 2 is provided on one side of the box body 1, a fixedly connected feed pipe 5 is penetrated on the other side of the box body 1, and a discharge end of the feed pipe 5 penetrates the connecting frame 2 and is located between the filter screen 21 and the bearing plate 22; a lifting plate 3 located above the filter screen 21 is provided in the box body 1, a thin rod 31 that can be inserted into the filter hole of the filter screen 21 is fixed on the bottom surface of the lifting plate 3, an electric telescopic rod 32 for driving the lifting plate 3 to rise and fall is provided on the box body 1, and an air outlet pipe 6 located below the connecting frame 2 is also provided in the box body 1.

[0016] like Figure 1 and Figure 2As shown, the motor 4 is fixed to the box body 1 through a fixing plate, and a rotating rod 41 penetrating the box body 1 and fixed to one side of the connecting frame 2 is fixed on the rotating shaft of the motor 4; the feeding end of the feeding pipe 5 is located above the discharging end and is connected to the feeding hopper 51, and a reinforcing plate 52 is fixed between the feeding hopper 51 and the box body 1, and a vibrator 53 connected to the vibrating end of the feeding pipe 5 is fixed on the reinforcing plate 52. After starting the motor 4, the connecting frame 2 can be driven to rotate through the rotating rod 41, so that the tea leaves in the connecting frame 2 can be repeatedly moved to ensure that all the tea leaves are thoroughly dried and dehydrated; the feeding end of the feeding pipe 5 is located above the discharging end, so that after the staff puts the tea leaves into the feeding hopper 51, the tea leaves can smoothly enter the connecting frame 2 through the feeding pipe 5, and the reinforcing plate 52 can increase the stability of the feeding hopper 51. When the tea leaves are discharged, the vibrator 53 can be started to vibrate the feeding pipe 5 to prevent the tea leaves from accumulating in the feeding pipe 5.

[0017] like Figure 2 and Figure 3 As shown, the top surface of the supporting plate 22 is arranged in an arc shape, two groups of springs 23 are provided, and the two groups of springs 23 are symmetrically distributed front to back. Two partitions 25 symmetrically distributed front to back are fixed to the bottom of the filter screen 21, and the two partitions 25 are located between the two groups of springs 23. The bottom surfaces of the two partitions 25 are respectively in contact with the top surface of the supporting plate 22, and the discharge end of the feed pipe 5 is located between the two partitions 25. The spring 23 can be a strong spring, and the arrangement of the two groups of springs 23 can effectively prevent the carrying plate 22 from moving at will, so that the carrying plate 22 can always be located in the connecting frame 2 to block the tea leaves without the influence of external forces; the partition 25 can block the spring 23 to prevent the tea leaves from being stuck on the spring 23, and the top surface of the carrying plate 22 is arranged in an arc shape (the side of the carrying plate 22 close to the filter screen 21), so that when the tea leaves are dehydrated and the carrying plate 22 is under the filter screen 21, the lifting plate 3 moves downward and contacts the top of the vertical rod 24. As the lifting plate 3 continues to move downward, the vertical rod 24 can push the carrying plate 22 downward, so that the spring 23 is stretched, and after the carrying plate 22 moves to the outside of the connecting frame 2, the tea leaves in the connecting frame 2 can fall downward through the opening at the bottom of the connecting frame 2; the arc-shaped top surface of the carrying plate 22 is also convenient for the tea leaves to slide downward.

[0018] like Figure 1 and Figure 2As shown, the lifting plate 3 is hollow, a group of perforations are formed on the bottom surface of the lifting plate 3, and the top of the lifting plate 3 is connected with a water inlet pipe 33 that penetrates the box body 1; the fixed end of the electric telescopic rod 32 is fixed to the top of the box body 1, and the telescopic end of the electric telescopic rod 32 penetrates the box body 1 and is fixed to the top of the lifting plate 3. The water inlet pipe 33 is connected to an external water source. When the connection frame 2 and the filter screen 21 are used for a long time, water can enter the lifting plate 3 through the water inlet pipe 33 and be discharged through the perforations to clean the inside of the connection frame 2 and the filter screen 21. The water inlet pipe 33 can be a rubber tube.

[0019] like Figure 1 and Figure 2 As shown, two connecting pipes 61 which are symmetrical on the left and right are slidably connected in the box body 1, and two groups of air outlet pipes 6 are provided. The two groups of air outlet pipes 6 are respectively connected with the two connecting pipes 61, and a screen 65 is fixed to the exhaust end of the air outlet pipe 6. The connecting pipe 61 is connected with a hose 62 which passes through the box body 1; an automatic telescopic rod 63 is fixed on both sides of the box body 1, and the telescopic end of the automatic telescopic rod 63 passes through the box body 1 and is fixed to the connecting pipe 61 through a short rod, and the fixed end of the automatic telescopic rod 63 is fixed with a connecting plate 64 connected to the box body 1. The hose 62 is connected to an external warm air device. When the warm air enters the connecting pipe 61 through the hose 62, it can be discharged through the exhaust end of a group of air outlet pipes 6 and blown to the connecting frame 2 to dry and dehydrate the tea leaves in the connecting frame 2; at the same time, the No. 1 automatic telescopic rod 63 can be started to make the connecting pipe 61 drive the air outlet pipe 6 to move back and forth horizontally to prevent the air outlet pipe 6 from always discharging toward one outlet, so that the air outlet pipe 6 can blow the warm air evenly to the connecting frame 2; the screen 65 can prevent impurities such as fine tea leaves from entering the air outlet pipe 6 through the top of the air outlet pipe 6.

[0020] like Figure 1 and Figure 2As shown, a discharge port 7 located below the air outlet pipe 6 is opened on one side of the box body 1, and an inclined guide plate 8 is fixed on the side of the box body 1 away from the discharge port 7. The lower side of the guide plate 8 passes through the discharge port 7 and extends to the outside of the box body 1, and a No. 2 vibrator 81 whose vibration end is connected to the guide plate 8 is fixed to the bottom of the box body 1; a No. 2 automatic telescopic rod 66 is fixed to the bottom of the connecting plate 64 close to the discharge port 7, and a baffle 67 for blocking the discharge port 7 is fixed to the telescopic end of the No. 2 automatic telescopic rod 66. When the fine tea leaves and impurities in the tea leaves fall downward, they are blocked by the guide plate 8, and then slide toward the discharge port 7 through the guide plate 8 and are discharged to the outside of the box 1 through the discharge port 7; after starting the second vibrator 81, the guide plate 8 can be vibrated to facilitate the fine tea leaves and impurities that fall on the guide plate 8 to slide down better; when the subsequent tea leaves are dehydrated, the tea leaves in the connecting frame 2 fall downward and also fall on the guide plate 8, and then are discharged through the discharge port 7; when the tea leaves are being dried and dehydrated, the baffle 67 can be used to block the discharge port 7. When the tea leaves are dried and dehydrated, the second automatic telescopic rod 66 is started again to move the baffle 67 away from the discharge port 7, first the fine tea leaves and impurities on the guide plate 8 are discharged, and then the tea leaves in the connecting frame 2 fall on the guide plate 8 and are discharged through the discharge port. The baffle 67 blocks the discharge port 7, which can prevent the rapid loss of heat in the box 1.

[0021] like Figure 1 , Figure 2 and Figure 3 As shown, an exhaust hood 9 is fixed on one side of the box body 1. The exhaust hood 9 is located below the discharge end of the feed pipe 5 and corresponds to one side of the connection frame 2. An exhaust hole is provided on one side of the exhaust hood 9 close to the connection frame 2. A circular hole with an inner diameter smaller than the inner diameter of the filter hole on the filter screen 21 is provided on the connection frame 2. The exhaust hood 9 is connected with an air delivery pipe 91 that runs through the box body 1. The air delivery pipe 91 is connected with an external fan. When tea leaves enter the connection frame 2 through the feed pipe 5, the filter screen 21 is located below the carrier plate 22. When tea leaves fall on the filter screen 21, the external fan can be started to allow air to enter the exhaust hood 9 through the air delivery pipe 91 and then be discharged through the exhaust holes on the exhaust hood 9. The tea leaves on the filter screen 21 can be blown toward the motor 4 to prevent the tea leaves from accumulating at the discharge end of the feed pipe 5 and affecting the normal discharge of the feed pipe 5.

[0022] like Figure 1 As shown, one side of the box body 1 is connected to an exhaust pipe 11, and one side of the box body 1 is hinged with a door panel 12. The exhaust pipe 11 can exhaust the air in the box body 1, and the staff can open the door panel 12 to inspect and maintain the parts inside the box body 1.

[0023] When in use, the tea leaves are discharged into the connecting frame 2 through the feeding pipe 5. When the tea leaves are discharged, the motor 4 can also be started to rotate the connecting frame 2 so as to disperse the tea leaves in the connecting frame 2. When the tea leaves are discharged, the hot air is discharged into the box body 1 through the air outlet pipe 6 and blown to the connecting frame 2 to dry and dehydrate the tea leaves in the connecting frame 2. The motor 4 adopts a servo motor. When the tea leaves are dehydrated, the motor 4 can drive the connecting frame 2 to rotate forward or reverse all the time, or the connecting frame 2 can be rotated forward slightly and then reversed slightly (when the small amplitude is reversed, the filter screen 21 is located below the supporting plate 22), so that the tea leaves in the connecting frame 2 can be moved repeatedly, so that the hot air can effectively dehydrate and dry all the tea leaves; the fine tea leaves in the tea leaves can fall downward through the filter holes on the filter screen 21, completing the dehydration of the tea leaves and the fine tea leaves. When the tea leaves are separated, after the dehydration is completed, the carrying plate 22 is located below the filter screen 21, and the electric telescopic rod 32 is started to move the lifting plate 3 downward. When the lifting plate 3 contacts the top of the vertical rod 24, as the lifting plate 3 continues to move downward, the carrying plate 22 can be pushed downward to move the carrying plate 22 downward to the outside of the connecting frame 2. After the spring 23 is stretched, the opening at the bottom of the connecting frame 2 is opened to facilitate the discharge of the tea leaves. At this time, the lifting plate 3 can be repeatedly lifted up and down by a small amplitude, so that the carrying plate 22 can be better discharged after the repeated up and down movement to generate a shake. When the tea leaves are discharged, the lifting plate 3 can continue to move downward to insert the thin rod 31 into the filter hole on the filter screen 21, so as to complete the dredging of the filter holes on the filter screen 21 and prevent impurities from being blocked in the filter holes.

[0024] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
