Sieve 19 is screened, and above step is repeated, when being blocked when being moved to immediately below sieve pore cleaning mechanism on one side, wait sieve
After selecting cabinet 1 to vibrate up and down steadily, start electric pushrod 7, drives support plate 6 to move downward by electric pushrod 7, make support plate
The strip plate 5 of 6 bottoms is inserted into corresponding long strip through hole 21, and screening cabinet 1 vibrates up and down, and strip plate 5 is in long strip through hole
Piston motion is done inside 21, the chamber volume size that strip plate 5 is formed with long strip through hole 21 constantly changes, and air pressure inside is just
Pressure persistently changes between negative pressure, by the variation of positive and negative air pressure, the sieve pore group 22 of sieve 19 is completed to blow, air-breathing it is dynamic
Make, reopen the sieve pore of blocking, strip plate 5 after a period of work, by the contraction of electric pushrod 7 by strip plate
Then 5 withdrawals drive screening cabinet 1 to rotate 60 degree again, repeat above step by stepper motor 9, continue screening cabinet 1
Vibration screening, while the sieve pore of blocking being reopened by sieve pore cleaning mechanism, flour screening operation and sieve pore cleaning work
It is synchronous to carry out, guarantee that the sieve pore moment is in the state opened, improve screening efficiency, promotes screening quality.
In order to improve the leakproofness between 21 inner wall of strip plate 5 and long strip through hole, strip plate 5 is circumferential to be connected with rectangle
Rubber seal 20.
21 depth 15-20mm of long strip through hole makes long strip through hole 21 have certain depth, makes strip plate 5, long strip through hole
Chamber between 21 can form the variation of positive and negative air pressure when screening cabinet and vibrating up and down.
It is inserted into inside long strip through hole 21, is completed between sieve pore cleaning mechanism and screening cabinet 1 for the ease of strip plate 5
Docking, long strip through hole 21 are directed toward extraneous one end and are circumferentially with chamfering, make to form wide-mouth shape outside long strip through hole 21.
The impurity screened inside cabinet 1 is cleared up away for convenience, the adjacent quadrilateral surface of screening 1 two of them of cabinet
Combine forming V-shape switching door 24, V-arrangement switching door 24 on one side by hinge hinge and screening cabinet 1 be rotatably connected, another side
It is fixed together by tight locking button 23 and screening cabinet 1, directly opens V-arrangement switching door 25, the impurity after internal screening is fallen
Out.
