Description

Technical Field

[0001] The utility model relates to the field of tea machines, in particular to a screening and grading device for a tea machine. Background Technique

[0002] Tea refers to the leaves and buds of the tea tree. Tea originated in China and was first used as a sacrifice. However, since the late Spring and Autumn period, it has been used as a vegetable food, developed into a medicinal use in the mid-Western Han Dynasty, and only developed into a high-class court beverage in the late Western Han Dynasty. Tea contains components such as catechins, cholestenone, caffeine, inositol, folic acid, and pantothenic acid, which can improve human health. Tea beverages are known as "one of the world's three major beverages". Tea processing includes picking, withering, fixing, rolling, ball rolling, piling, drying, etc.

[0003] Among the many links of tea processing, the conventional tea screening and grading device has unsatisfactory flow and dispersion in actual application, resulting in a slow screening process, consuming a large amount of time. At the same time, the grading accuracy is also unsatisfactory. It is often difficult to accurately divide tea into different quality grades in detail, making the quality of the finally produced tea uneven, affecting the market value of tea. Therefore, we propose a screening and grading device for a tea machine to solve the above problems. Content of the Utility Model

[0004] The purpose of the utility model is to provide a screening and grading device for a tea machine to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] A screening and grading device for a tea machine includes a device body. The upper surface of the device body is fixedly communicated with a hopper. The left side surface of the device body is provided with a first discharge port. A sloping plate is hinged to the inner wall of the first discharge port. The back surface of the device body is provided with a second discharge port. An extension plate is fixedly connected to the inner wall of the second discharge port. The back surface of the device body is provided with a third discharge port. A transmission mechanism is fixedly connected to the inner bottom wall of the device body. A diversion plate is fixedly connected to the inner wall of the device body. An installation groove is provided on the inner wall of the device body. A group of buffer dampers are fixedly connected to both the inner bottom wall and the inner top wall of the installation groove. A spring is sleeved on the outer surface of each buffer damper. A first-stage sieve mesh is fixedly connected to the side surfaces of the two buffer dampers close to each other. The back surface of the first-stage sieve mesh is hinged to the inner wall of the second discharge port. A first vibration motor is fixedly connected to the bottom surface of the first-stage sieve mesh. A second-stage sieve mesh is hinged to the inner wall of the device body. A second vibration motor is fixedly connected to the bottom surface of the second-stage sieve mesh.

[0007] In a further embodiment, a touch panel is fixedly connected to the front surface of the device body.

[0008] In a further embodiment, a potential seat is fixedly connected to the front surface of the device body, and a group of alarm display lights are fixedly connected to the front surface of the potential seat.

[0009] In a further embodiment, a maintenance opening is provided on the right side surface of the device body, and a maintenance plate is fixedly connected to the right side surface of the maintenance opening by bolts.

[0010] In a further embodiment, a parameter label is fixedly connected to the front surface of the device body.

[0011] In a further embodiment, two support legs are fixedly connected to the bottom surface of the device body, a support foot is fixedly connected to the bottom surface of each support leg, and a mounting hole is provided on the upper surface of each support foot.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] In this device, the first vibration motor drives the first-stage screen to vibrate. The tea leaves that meet the aperture requirements of the first-stage screen pass through the screen and fall down, while the larger tea leaves that do not meet the requirements move towards the second discharge port under the vibration action and are finally discharged through the extension plate, greatly shortening the screening time and improving the overall screening efficiency. The tea leaves that have passed through the first-stage screening fall on the second-stage screen, and the second vibration motor drives the second-stage screen to vibrate. The tea leaves that meet the aperture requirements of the second-stage screen continue to fall, and the tea leaves that do not meet the requirements are discharged through the first discharge port under the vibration action. The tea leaves that have passed through the second-stage screening fall on the transmission mechanism and are conveyed to the third discharge port for discharge. The screens with different apertures can more accurately classify the tea leaves according to the particle size, making the finally obtained tea leaves of different grades purer.
