Description

A tea fresh leaf grading machine

technical field

The utility model relates to the field of tea processing equipment, in particular to a tea fresh leaf classifier.

Background technique

Most of the fresh leaf classification of tea adopts conical sieve cylinder to sieve the fresh leaves of tea, but in practical application, when processing for a short period of time, the sieve holes on the sieve cylinder are often partially blocked by fresh leaves. To solve this problem, someone applied a vibrating device at both ends of the screen cylinder to prevent fresh leaves from clogging. The fresh leaves flow to the big end of the sieve cylinder, resulting in poor classification effect.

Utility model content

The purpose of the utility model is to provide a tea fresh leaf classifier with simple structure, low failure rate and good classification effect.

The specific technical solution of the utility model is: a tea fresh leaf classifier, comprising a base, the base is provided with a tapered screen drum, and the screen drum is provided with a plurality of screen holes, from The sieve holes in the direction from the small end of the sieve cylinder to the large end of the sieve cylinder gradually increase in diameter; the large end of the sieve cylinder is connected with a first drive motor that drives the sieve cylinder, and the sieve cylinder The small end of the small end is provided with an input port for inputting fresh leaves, and the base is also provided with a material receiving guide groove under the screen drum, and a blower device is provided on the side close to the large end of the screen drum, and the drum The wind device includes a fan and a second drive motor connected to the fan drive.

In the above-mentioned tea fresh leaf classifier, the material receiving guide groove is composed of a first guide groove, a second guide groove, and a third guide groove arranged side by side, and the bottom surface of the first guide groove, the second guide groove The bottom surface of the groove and the bottom surface of the third guide groove are all stainless steel arc plates.

In the fresh tea leaf classifier mentioned above, a trough connected to the input port is provided on the side close to the small end of the sieve cylinder.

Compared with the prior art, the utility model has the beneficial effects of:

1. This scheme abandons the vibration device used in the traditional grading equipment, and uses the blower device installed at the large end of the screen drum to improve the grading effect, which simplifies the equipment and reduces the processing difficulty of the equipment, and blocks fresh leaves. Under the continuous action of the wind force, the sieve holes will quickly fall off from the sieve holes. More importantly, the blower device makes it easy for small broken leaves to stay on the small end of the sieve cylinder, and larger fresh leaves will be more crushed than broken leaves. Leaves are more inclined to move quickly towards big endian.

2. This scheme adopts the first guide groove, the second guide groove and the third guide groove, which are helpful for classifying and outputting the tea leaves.

detailed description

The technical solution of the present utility model will be further described in detail below in combination with specific implementation methods, but this does not constitute any limitation to the present utility model.

Example 1

As shown in Figures 1 and 2, a tea fresh leaf classifier includes a base 1, and the base 1 is provided with a conical screen drum 2, and the screen drum 2 is provided with a plurality of screens. hole 3, from the small end of the screen cylinder 2 to the direction of the large end of the screen cylinder 2, the aperture of the screen hole 3 gradually increases; the large end of the screen cylinder 2 is connected to the drive of the screen cylinder 2 The first drive motor 4, the small end of the sieve cylinder 2 is provided with an input port 5 for inputting fresh leaves, and the side close to the small end of the sieve cylinder 2 is provided with a trough 6 communicated with the input port 5, the described The base 1 is also provided with a material receiving guide groove 7 located below the screen cylinder 2, and a blower device is provided on the side close to the large end of the screen cylinder 2, and the blower device includes a fan 8 and an air blower connected to the fan 8 for driving. The second drive motor 9.

In this embodiment, the material receiving guide groove 7 is composed of a first guide groove 71, a second guide groove 72, and a third guide groove 73 arranged side by side. The bottom surface of the first guide groove 71, the second guide groove The bottom surface of the guide groove 72 and the bottom surface of the third guide groove 73 are stainless steel arc plates.

In practical application, the tea leaves are input into the sieve cylinder 2 from the input port 5 according to the designed amount from the hopper 6, the first drive motor 4 is started to drive the sieve cylinder 2 to rotate, and the second drive motor 9 is started at the same time, and the fan 8 starts Running, in the screening process, the smaller tea leaves can fall into the first guide groove 71 at the small end side, and the larger tea leaves move to the large end, and the wind will blow down the broken leaves blocked on the sieve hole 3, At the same time, under the action of wind force, smaller tea leaves will stay on the side close to the small end, so as to achieve the purpose of full grading.

The above are only preferred embodiments of the present utility model, and any modifications, equivalent replacements and improvements made within the spirit and principle scope of the present utility model shall be included in the protection scope of the present utility model.
