[0022] To make the objectives, technical solutions, and advantages of the present utility model clearer and more understandable, the present utility model will be further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of the present utility model. In addition, in the following descriptions, the descriptions of well-known structures and technologies are omitted to avoid unnecessarily confusing the concepts of the present utility model.

[0023] Please refer to Figures 1-3 , a tea pretreatment device, including a screening box 1. Inside the screening box 1, there is a conveyor roller 2, and a speed reducer 4 is installed at the end of the conveyor roller 2. The speed reducer 4 is connected to a servo motor 5. A filter screen type conveyor belt 3 is arranged on the surface of the conveyor roller 2. Partition plates 10 are arranged on the surface of the filter screen type conveyor belt 3. Side plates 11 are arranged on the inner top surface of the screening box 1. Bouncing balls 12 are arranged on the inner side surface of the side plates 11. Through holes are formed on the side surface of the screening box 1, and a storage box 8 is arranged at the through holes. A vibration motor 6 is arranged on the side surface of the screening box 1. A feeding bin 9 is arranged on the upper surface of the screening box 1.

[0024] In this embodiment: When in use, the tea is put into the feeding bin 9, and then it drops from the feeding bin 9 onto the filter screen type conveyor belt 3. Then, the vibration motor 6 and the servo motor 5 are started. The vibration motor 6 drives the entire screening box 1 to vibrate, thereby vibrating and screening the tea. At the same time, the tea moves to the lower side. The servo motor 5 drives the conveyor roller 2 through the speed reducer 4, thereby slowly driving the filter screen type conveyor belt 3 to rotate in a direction opposite to the moving direction of the tea. When the dropping speed of the tea is greater than the conveying speed of the filter screen type conveyor belt 3, the tea still moves to the lower side of the filter screen type conveyor belt 3. The structure of the present utility model is simple and easy to operate, greatly extending the conveying distance of the filter screen type conveyor belt 3 for the tea and prolonging the time of the tea on the filter screen type conveyor belt 3, so as to fully perform the screening and pretreatment operation on the tea and maintain the cleanliness of the tea. The setting of the bouncing balls 12 will bounce along with the vibration screening operation and react on the filter screen type conveyor belt 3, further improving the vibration intensity of the filter screen type conveyor belt 3 and enhancing the screening effect.

[0025] Specifically, a part of the filter screen type conveyor belt 3 is arranged in an inclined direction, and the inclination angle is 30 degrees with respect to the horizontal direction.

[0026] In this embodiment: During the vibration screening operation, the tea will move to the lower side under the action of gravity, thereby achieving the purpose of driving the movement of the tea.

[0027] Specifically, a guide plate 13 is arranged on the side surface of the screening box 1.

[0028] In this embodiment: It guides the screened tea for convenient collection.

[0029] Specifically, a support plate 7 is provided inside the screening box 1 and below the storage frame 8.

[0030] In this embodiment: It plays a supporting role for the screening box 1.

[0031] Specifically, the lower surface of the screening box 1 is provided with feet 14.

[0032] In this embodiment: It plays a supporting role for the screening box 1.

[0033] Specifically, a control panel 15 is provided on the side surface of the screening box 1.

[0034] In this embodiment: By setting the control panel 15, it is used to control the pretreatment screening device. The control circuit of the control panel 15 can be realized by simple programming by those skilled in the art, which belongs to the common knowledge in the art. Only its use is involved without modification, so the control method and circuit connection will not be described in detail.

[0035] Working principle: When in use, the tea leaves are put into the feeding bin 9, and then fall from the feeding bin 9 onto the filter belt conveyor 3. Then, the vibration motor 6 and the servo motor 5 are started. The vibration motor 6 drives the entire screening box 1 to vibrate, thereby vibrating and screening the tea leaves. At the same time, the tea leaves move to the lower side. The servo motor 5 drives the conveying roller 2 through the reducer 4, thereby slowly driving the filter belt conveyor 3, so that the filter belt conveyor 3 rotates in the opposite direction to the moving direction of the tea leaves. When the falling speed of the tea leaves is greater than the conveying speed of the filter belt conveyor 3, the tea leaves still move to the lower side of the filter belt conveyor 3. The structure of the present utility model is simple and easy to operate, greatly extending the conveying distance of the filter belt conveyor 3 for the tea leaves and prolonging the time of the tea leaves on the filter belt conveyor 3, so as to fully perform the screening and pretreatment operation on the tea leaves and keep the tea leaves clean. The setting of the bouncing balls 12 will bounce along with the vibration screening operation and react on the filter belt conveyor 3, further improving the vibration intensity of the filter belt conveyor 3 and enhancing the screening effect.
