Therefore, in the process of tea processing, screening is becoming more and more important. Traditional tea screening generally adopts manual screening, using screens to filter and select tea, which has cumbersome steps and wastes manpower.

[0003] Announcement No. CN216368977U proposes a novel tea screening and selection device, which can improve the screening quality of tea and reduce waste; however, the tea leaves in the device are concentrated after entering from the feed hopper, which will cause some fine tea leaves to flow out with better quality tea leaves without sufficient vibration screening, and the screening and selection effect needs to be improved. At the same time, the layout distance of the discharge pipe is relatively long, which will cause the tea leaves to scatter everywhere after screening, making it inconvenient to collect. Utility Model Content

[0007] The device can realize the uniform feeding of tea leaves into the screening box. After the tea leaves fall onto the screen, they can be effectively dispersed under the action of the vibration motor without causing concentrated accumulation. This reduces the probability of small tea leaves being discharged directly from the first discharge pipe together with tea leaves of better quality, and the screening and differentiation effect is improved. At the same time, different tea leaves after screening will be stored in corresponding collection boxes and dried. Subsequently, the collection boxes can be taken out and directly dumped for classified storage, without causing the tea leaves to be scattered everywhere, and the tea leaves can be better collected.

[0008] Furthermore, the heating assembly includes a heater, a cylinder, a rotating shaft, a turning rod and a servo motor. A heater is arranged inside the collection box, a cylinder is arranged on the conveying box, the cylinder is connected to the servo motor inside the conveying box, the servo motor is connected to the rotating shaft, and several turning rods are symmetrically arranged on the rotating shaft.

[0009] The above scheme can evenly dry the tea leaves after screening in the collection box through the heating component to prevent the tea leaves from getting damp.

[0010] Furthermore, each of the conveying boxes is provided with a return pipe connected to the interior of the screening box.

[0011] The above scheme can transfer the waste heat in the process of turning and drying the tea leaves back to the inside of the screening box through the reflux pipe to perform preliminary drying on the subsequent tea leaves, which can reduce energy consumption.

[0012] Furthermore, the screening box comprises a discharge port, and the discharge port is connected to the impurity box through a discharge pipe.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] Compared with the existing technology, the device can realize the uniform feeding of tea leaves into the screening box. After the tea leaves fall onto the screen, they can be effectively dispersed under the action of the vibration motor without causing concentrated accumulation. This reduces the probability of small tea leaves being discharged directly from the first discharge pipe together with tea leaves of better quality, and the screening and differentiation effect is improved. At the same time, different tea leaves after screening will be stored in corresponding collection boxes and dried.

[0022] like Figure 1 and Figure 2 As shown, a novel tea screening device comprises a screening box 2 and a feeding conveyor belt 1 arranged on one side of the screening box 2. The top of the screening box 2 is connected to a discharger 21. In this application, a star-shaped discharger can be specifically used. The discharger 21 is connected to a feed hopper 22. The discharge end of the feeding conveyor belt 1 is located above the feed hopper 22. The inside of the screening box 2 is sequentially provided with a first screen 24, a second screen 25 and a third screen 26 with a main body shape of an arc and obliquely staggered arrangement from top to bottom. The screening box 2 is provided with a vibration motor 23 And circular discharge ports 27 corresponding one to one with the first screen 24, the second screen 25 and the third screen 26, the discharge ports 27 are connected to the conveying box 3 through the discharge channel 28, the conveying boxes 3 are arranged on both sides of the screening box 2 and are distributed one to one with the discharge ports 27, each conveying box 3 is provided with a collecting box 32 and a heating component inside, and a box door 31 is provided on the conveying box 3; the screening box 2 includes a discharge port 201, the discharge port 201 is connected to the impurity box through a discharge pipe, and the discharge pipe and the impurity box are shown without numbering in the figure.

[0023] Specifically, the heating component includes a heater 33, a cylinder 44, a rotating shaft 42, a turning rod 43 and a servo motor 41. The heater 33 is arranged inside the collecting box 32, and the cylinder 44 is arranged on the conveying box 3. The cylinder 44 is connected to the servo motor 41 inside the conveying box 3. The servo motor 41 is connected to the rotating shaft 42, and a plurality of turning rods 43 are symmetrically arranged on the rotating shaft 42.

[0025] The workflow of this utility model:

[0026] First, add tea leaves evenly onto the feeding conveyor belt 1. When the tea leaves are transported to the end of the feeding conveyor belt 1, they will fall into the feeding hopper 22. At this time, the controller controls the star-shaped discharger to make the tea leaves evenly enter the screening box 2, and will not cause the problem of tea leaves piling up due to a large amount of tea leaves entering. Then the controller controls the vibration motor 23 to work. The tea leaves are successively screened through three levels to screen out the tea leaves with better quality, fine tea leaves and tea foam. The remaining impurities will flow into the impurity box from the discharge port 201 for storage and recovery. After the screening, the multi-layer tea leaves will flow along the bottom of the corresponding screen under the action of the vibration motor 23, and finally flow out of the screening box 2 through the discharge port 27, and then enter the conveying box 3 along the discharge channel 28 and finally fall into the collecting box 32. At this time, the controller controls the heater 33, the servo The servo motor 41 and the cylinder 44 work at the same time, and the heater 33 works to generate heat. The cylinder 44 works to make the servo motor 41, the rotating shaft 42 and the turning rod 43 move downward inside the conveying box 3. Then, along with the work of the servo motor 44, the turning rod 43 can turn the tea leaves to make the drying more uniform. After the drying is completed, the controller controls the cylinder 44 to retract. At this time, the cylinder 44 drives the turning rod 43 to leave the collecting box 32, and then the controller controls the servo motor 44 and the heater 33 to stop working. Then, the box door 31 can be opened to take out the collecting box 32 for the dumping, classification and storage process of the tea leaves. After all the tea leaves in the collecting boxes 32 are dumped, classified and stored, they are put back into the conveying box 3 to start a new round of tea screening process.

[0027] Compared with the prior art, the present device can realize uniform feeding of tea leaves into the screening box 2. After the tea leaves fall onto the screen, they can be effectively dispersed under the action of the vibration motor 23 without causing concentrated accumulation. This reduces the probability of fine tea leaves being discharged directly from the first discharge pipe together with tea leaves of better quality, and the screening and differentiation effect is improved. At the same time, different tea leaves after screening will be stored in the corresponding collection box 32 and dried. Subsequently, the collection box 32 can be taken out and directly dumped for classified storage, without causing the tea leaves to be scattered everywhere, and the tea leaves can be better collected.

[0028] In some embodiments, Figure 2 As shown, each conveying box 3 is provided with a return pipe 5 connected to the interior of the screening box 2; this embodiment can re-transport the waste heat in the process of turning and drying the tea leaves to the interior of the screening box 2 through the return pipe 5 to perform preliminary drying on the subsequent tea leaves, which can reduce energy consumption.

[0029] In other embodiments, Figure 1 As shown, the bottom end of the feed pipe is flush with the feed opening of the impurity box; this embodiment facilitates the removal of the impurity box for cleaning of internal impurities and can also effectively reduce the overflow of dust.
