Embodiment Construction

[0016] The present invention will be further described below in conjunction with the examples, but the protection scope of the present invention is not limited thereto.

[0017] refer to figure 1 , an inclined sieve disc type tea classifier, comprising a frame 1, a transmission mechanism 2, a corner rotating device 3, and a screening device 4;

[0018] The angle rotating device 3 tilts the screening device 4 at a certain angle, and rotates the screening device 4 during operation;

[0019] The screening device 4 is composed of four sieve trays 5 superimposed, and the sieve mesh holes decrease layer by layer from top to bottom, the sieve mesh holes of the uppermost sieve tray are the largest, and the sieve trays of the lowermost sieve tray have the smallest mesh holes;

[0020] The sieve tray 5 is made of a screen 6 and a side ring 7;

[0021] The sieve pan edge ring 7 is two concentric circles with a gap, the inner ring is connected with the outer ring at the gap, and the sha...

Abstract

The invention relates to an inclined sieve tray type tea grader. The inclined sieve tray type tea grader comprises a rack, a transmission mechanism, a corner rotating device and a screening device. The screening device is formed by stacking multiple sieve trays. The size of screen holes is reduced layer by layer from top to bottom. The transmission mechanism is mounted on the rack. The corner rotating device is in linkage with a main shaft of the transmission mechanism. The screening device is in linkage with an output shaft of the corner rotating device. In the operation process, the screening device rotates and moves. For the screening device, two rotating modes can be selected; according to the first rotating mode, the main shaft of the transmission mechanism serves as the center to conduct pure rolling and rotating in the axial direction; and according to the second rotating mode, an output shaft of the corner rotating device serves as the center and rotates. Tea is put into the center of the upper sieve trays on the screening device and rolls on the screening face, the tea of which the size is smaller than that of the screen holes falls into the lower-layer sieve trays, and the tea of which the size is larger than that of the screen holes is discharged through tea discharging openings in the sieve tray edge rings. The inclined sieve tray type tea grader has the beneficial effects that the tea grading effect is good, efficiency is high, the tea damage rate is low, the structure is simple, and operation is easy and convenient. Appropriate screen cloth is selected and used, and the inclined sieve tray type tea grader can be used for screening and grading fresh tea leaves and purified tea.

Description

(1) Technical field [0001] The invention relates to an inclined sieve disc type tea classifier. (2) Background technology [0002] With the development of agricultural mechanization, manual tea picking in the past has been gradually replaced by tea picking machines. The tea leaves picked by tea picking machines are of different lengths, different ages, single pieces, more clips, and low uniformity, which affect the quality of tea processing. , reducing the income of tea farmers. The purpose of grading fresh leaves: 1. To ensure the uniformity of buds and leaves in the same batch, which is convenient for mastering the tea making process; 2. The grading system can obtain the best economic benefits from the aspects of high quality, high price and neat products. [0003] At present, tea processing and production enterprises generally use drum-type fresh leaf classifiers for grading. The drum-type fresh leaf classifiers are driven by a motor through a belt drive, decelerated by ...
