Abstract

The invention discloses a four-stage tea leaf screening machine. The four-stage tea leaf screening machine comprises a power device, a motor rack, a baffle screen frame, a feeding funnel, baffle screens, fixing blocks and pulley guide rails. According to the four-stage tea leaf screening machine disclosed by the invention, mechanical operation on tea leaf screening is realized; the production efficiency is greatly increased; screening on 300 to 400 kilograms of raw materials can be completed per hour, and the screening efficiency cannot be achieved by manual screening; meanwhile, the baffle screens with fixed net openings are adopted, thus the specifications of screened tea leaves can be more uniform during the tea leaf screening; the situations that the duration and degree of heating and the baking time are difficult to master as the tea leaves are inconsistent in sizes cannot be caused during baking at a later stage, the quality and appearance of manufactured tea leaves is better, and the economic value is high.

Description

A kind of level Four sieve tea machine

Technical field

The present invention relates to tea machinery sub-sieve field, particularly relate to a kind of level Four sieve tea machine.

Background technology

Qualities different according to tealeaves in tealeaves manufacturing process, needs the size of tealeaves according to its blade to classify, to reach exquisite object; But existing technology adopts mostly manually carries out, and so not only wastes time and energy, and production efficiency is also very low, and artificial sub-sieve tealeaves specification is out often inconsistent, there will be leaf blade size difference, not only impact makes tealeaves manufacture craft, the tealeaves product made are not good mutually yet, affect economic benefit.

Summary of the invention

The object of the invention is point tea machine that designs a mechanism, realize the classification of tealeaves fast, improve prouctiveness, ensure that the tealeaves specification of sub-sieve is identical simultaneously.

In order to solve the problem, the technical solution used in the present invention is: a kind of level Four sieve tea machine, comprises power set, motor rack 1, gear screen frame (unit) 2, elevating hopper 3, gear sieve 4, fixed block 5, pulley guide rails 6;

Described power set are made up of motor 7, belt pulley, belt 8, crank block 12, belt pulley has three, be bull wheel 9 respectively, middlely take turns 10 and steamboat 11, wherein bull wheel 9 and steamboat 11 are set together, and both are coaxial, and motor 7 is connected with bull wheel 9 by belt 8, steamboat 11 with in take turns 10 and be connected by belt 8, take turns on 10 during crank block 12 one end is fixed on, the other end is connected with fixed block 5 by axle, makes rotary motion convert straight reciprocating motion to; Described motor rack 1 is of a size of each 0.4m of length and width, high 0.9m, and motor 7 is fixed on motor rack 1 bottom surface, and belt pulley is fixed in motor rack 1; Described gear screen frame (unit) 2 is of a size of long 1.5m, wide 0.8m, high 0.6m; Described elevating hopper 3 is in an inverted cone, and upper opening length and width are all 0.6m, and lower openings length and width are all 0.4m, is fixed on gear screen frame (unit) 2 side, and downward mouth is apart from gear sieve 15cm; This design advantage, when material loading, can ensure that tealeaves can not be piled up under mouth upstairs, result in blockage, described gear sieve 4 totally three, and be fixed as upper, middle and lower three layers by fixed block, bottom gear sieve 4 is provided with pulley 13, and pulley 13 is fastened in pulley guide rails 6; Described pulley guide rails 6 is fixed on bottom gear screen frame (unit) 2, has two sections of pulley guide rails be arranged in parallel 6.

Be variable-frequency motor based on upper described motor 7.

Based on above-mentioned belt pulley bull wheel 9 diameter 25cm, middlely take turns 10 diameter 16cm, steamboat 11 diameter 8cm, contribute to increasing moment of torsion, reduce torsion, make the structure of system more stable.

Upper strata gear sieve 4 sieve aperture 1mm is respectively, middle level gear sieve 4 sieve aperture 0.6mm, bottom gear sieve 4 sieve aperture 0.1mm based on above-mentioned three gear sieve 4 slot sizes.

Be fixed with discharging opening 14, discharging opening 14 one-tenth V-type based on above-mentioned gear sieve 4, the advantage of this design is, reduces the area of discharging opening, prevents from collecting point situation that the appearance be sieved is unrestrained.

3. being based on above-mentioned pulley guide rails 6 is parallel two sections, and the pulley guide rails 6 under discharging opening is apart from ground 15cm, and another pulley guide rails 6 is apart from bottom surface 20cm.

When the advantage of this design is sub-sieve tealeaves, facilitating the tealeaves under sub-sieve to flow to discharging opening voluntarily, avoiding people for going cleaning.

Beneficial effect of the present invention: the present invention makes tealeaves sub-sieve achieve the operation of mechanization, improve production efficiency greatly, the sub-sieve that can complete 300-400 kilogram of raw material per hour, this is that artificial sub-sieve is difficult to reach, and adopts the gear sieve of fixing network interface simultaneously, when sub-sieve tealeaves, the blade specification more unification of sub-sieve, when the later stage cures, can not because of leaf blade size different cause occur the duration and degree of heating, cure the time be difficult to hold, the tealeaves product made are better mutually, and economic worth is high.
