Background technology
The tealeaves circular screening machine is one of capital equipment in Tea Processing, and its difference according to shape of tea, length, thickness, granular size etc. is crossed sieve classification by tealeaves, and it drives screen movement by motor through transmission mechanism, makes tealeaves carry out sieve classification in motion process.
At present, what in the Tea Processing industry, tealeaves is carried out to initial screening generally adopts is the plane rotary strainer, often only adopt a standard to screen tea raw material, so just cause and tea raw material thickness inequality still occurs after screening, the situation that impurity is more, if use a plurality of vibratory sieves, each vibratory sieve all needs to arrange vibrating mechanism, and manufacturing cost is high.And existing tealeaves circular screening machine is in when work, the particle in tealeaves and dust can constantly be blown out from the tealeaves circular screening machine, and causing near the tealeaves circular screening machine is all dust, affects environment.
The utility model content
For solving the defect existed in above-mentioned prior art, the utility model provides a kind of tea screening device, can screen fully tealeaves, has that screening effeciency is high, the screening accuracy is strong, simple in structure, and can prevent the effect of tealeaves dust from flying.
The technical solution of the utility model is for providing a kind of tea screening device, comprise screening bed and screening plant, described screening plant comprises motor, eccentric wheel and power transmission shaft, described motor is by belt band movable eccentric wheel, described eccentric wheel drives power transmission shaft and moves back and forth at vertical direction, described power transmission shaft drives screen cloth and moves back and forth at vertical direction, described screening bed is provided with at least tilting screen cloth of one deck, described screen cloth is fixedly connected with power transmission shaft, described screening bed is provided with airduct, and described airduct is connected with dust catcher.
Preferably, in above-mentioned tea screening device, described power transmission shaft and screen cloth upwards an end are fixed or are fixed with screen cloth horizontal direction mid point.
Preferably, in above-mentioned tea screening device, described screening bed is provided with two-layer screen cloth.
Preferably, in above-mentioned tea screening device, the described two-layer screen cloth mesh of screen cloth at the middle and upper levels is greater than the mesh of lower screen.
Preferably, in above-mentioned tea screening device, in described screening bed, the vertical oblique lower end position of ground floor screen cloth of direction from top to bottom is provided with the discharging opening matched with every layer of screen cloth, and described discharging opening is provided with the static selecting device.
The tea screening device that the utility model provides has following advantage: utilize multilayer screen cloth to be screened tealeaves, the screening precision has had very big lifting, and a drive motors can drive a plurality of screen clothes, and drive mechanism is simple, low cost of manufacture.And on the tea screening device, be connected with dust suction its, the dust suction can be in time the tea screening device produced, prevent that dust from waving, and keeps the clean of workplace, the protection producers' is healthy.
The accompanying drawing explanation
Fig. 1 is the utility model tea screening apparatus structure schematic diagram;
1, screening bed; 2, motor; 3, eccentric wheel; 4, power transmission shaft; 5, screen cloth; 6, discharging opening; 7, charging aperture; 8, airduct; 9, dust catcher.
The specific embodiment
By describing technology contents of the present utility model, structural feature in detail, being realized purpose and effect, below in conjunction with embodiment and coordinate accompanying drawing to be explained in detail.
Refer to Fig. 1, the utility model provides a kind of tea screening device, comprise screening bed 1 and be arranged at the screening plant in screening bed 1, described screening plant comprises motor 2, eccentric wheel 3 and power transmission shaft 4, described motor 2 is by belt band movable eccentric wheel 3, and described eccentric wheel 3 drives power transmission shaft 4 and moves back and forth at vertical direction, and described screening bed 1 is provided with the tilting screen cloth of multilayer 5, described screen cloth 5 is fixedly connected with power transmission shaft 4, and described power transmission shaft 4 drives screen cloth 5 and moves back and forth at vertical direction.Described screening bed is provided with airduct 8, and described airduct is connected with dust catcher 9, and described airduct 8 is established the top with screen cloth 5, can better aspirate dust.
In a specific embodiment of the present utility model, screening bed described in above-mentioned tea screening device 1 is provided with two-layer screen cloth 5, and described two-layer screen cloth 5 mesh of screen cloth 5 at the middle and upper levels is greater than the mesh of lower screen 5.Described screening bed 1 upper end is provided with charging aperture 7, during use, tealeaves enters screening bed 1 from charging aperture 7, power transmission shaft 4 drives screen cloth 5 screening tealeaves, the grid of the superiors' screen cloth 5 filters out more greatly the tealeaves that build is larger, next time, screen cloth 5 grids diminished than upper strata, filter out the tealeaves of different length, thickness and size, realize the tea leaf quality normalization, improved the screening precision.
In a specific embodiment of the present utility model, power transmission shaft described in above-mentioned tea screening device 4 with screen cloth 5 horizontal direction mid points, fix or with screen cloth 5 upwards an end fix, this structure has improved the vibration efficiency of power transmission shaft 4.
