The method of work of dark brownish green screening machine
Technical field
The present invention relates to a kind of method of work of dark brownish green screening machine, belong to agricultural machinery technological field.
Background technology
Lao Ye larger to fresh leaf, profile and part leaf bar, when picking tea-leaves, together cut and collect by existing automatic tea plucker, and fresh leaf needs manually to screen separately, causes time-consuming taking a lot of work.
Summary of the invention
Technical problem that what the present invention will solve want be to provide a kind of can Automatic sieve except the larger Lao Ye of profile and base of leaf, again can Automatic sieve except the method for work of the dark brownish green screening machine of disintegrating slag, to reduce the man-hour that subsequent artefacts screens required fresh leaf.
For solving the problems of the technologies described above, the dark brownish green screening machine that the present invention proposes, comprising: hopper, the motor-driven valve be located on described feed hopper bottom discharging opening, is located at the screening framework below described discharging opening, is located at the upper and lower screen cloth distributed up and down on this screening framework;
The mesh size of described upper screen cloth is suitable for sieving out blade and the base of leaf that length is greater than 3cm; The mesh size of described lower screen cloth is suitable for sieving out blade and the base of leaf that length is greater than 0.5cm; Cursor is provided with below the left end of described screening framework, one end of this cursor is connected with the end bearing of a power transmission shaft, the other end of this cursor is fixedly connected on the output shaft of a motor, and described cursor is vertical with the output shaft of described power transmission shaft, described motor;
Described power transmission shaft is located at the bottom of this screening framework; Be snug fit at respectively by pulley bottom the right-hand member both sides of described screening framework on the slide rail of about a pair distribution;
When controlling described motor and driving described cursor to rotate, described upper and lower screen cloth is suitable for left and right fast offset, and the left end of this upper and lower screen cloth is suitable for upper and lower fast offset simultaneously, thus the dark brownish green realization on upper and lower screen cloth is sieved fast.
Described screening framework comprises the base plate be in below described lower screen cloth, the column that two couple being located at the both sides of this base plate is flexibly connected with the forward and backward frame of described upper and lower screen cloth respectively; One column of contiguous described upper and lower screen cloth right-hand member is right-hand member column, each right-hand member column comprises: be movably connected in two pairs of nuts on the forward and backward frame of described upper and lower screen cloth, screw mandrel before coordinating with a pair nut thread in the front bezel of described upper and lower screen cloth, the rear screw mandrel coordinated with a pair nut thread on the rear frame of described upper and lower screen cloth, is located at a pair motor for driving described forward and backward screw mandrel to rotate respectively of side before and after described base plate; The Right Border of described upper and lower screen cloth is provided with in trumpet-shaped discharging opening, and each discharging opening is provided with collecting bag; After described upper and lower screen cloth completes screening, open a pair described motor simultaneously, to be tilted to the right by described upper and lower screen cloth, thus dark brownish green on upper and lower screen cloth is entered each collecting bag fast.Described motor is electro-motor or hydraulic motor.
Rounded as the mesh on a kind of preferred upper and lower screen cloth, or upper and lower screen cloth adopts honeycombed screen plate, blocks to avoid upper and lower screen cloth.
The method of work of above-mentioned dark brownish green screening machine, it comprises:
A, the dark brownish green feeding hopper that will pluck;
B, open described motor-driven valve, to deliver on upper screen cloth by dark brownish green, then close this motor-driven valve;
C, open described motor with control described cursor rotate, and drive described upper and lower screen cloth left and right fast offset by described screening framework, the left end of this upper and lower screen cloth is suitable for upper and lower fast offset simultaneously, length is not more than the blade of 3cm and base of leaf drops down onto on lower screen cloth through upper screen cloth, and the disintegrating slag that length is not more than 0.5cm drops down onto on base plate through lower screen cloth;
D, implement after above-mentioned steps C reaches 2-5 minute, to control described upper and lower screen cloth and be tilted to the right, under the effect of described cursor, dark brownish green on described upper and lower screen cloth enters each collecting bag (discharging opening that described disintegrating slag is suitable on the right side of described base plate is discharged) fast; Then control described upper and lower screen cloth and return to the initial position parallel with described base plate;
E, repetition above-mentioned steps B.
The invention has the beneficial effects as follows: dark brownish green screening machine of the present invention, can be dark brownish green by batch screening, the larger Lao Ye of profile and base of leaf can be screened out, can disintegrating slag be screened out again, decrease the man-hour that subsequent artefacts screens required fresh leaf.Wherein, adopt cursor to drive described upper and lower screen cloth left and right fast offset, can sieve dark brownish green; Meanwhile, cursor is suitable for the upper and lower fast offset of left end driving described upper and lower screen cloth, and then makes the dark brownish green realization on upper and lower screen cloth turn over work of quivering, and is beneficial to quick screening further, avoids upper and lower screen cloth to occur blocking.
