Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and the technical solution in example of the present invention is described.
Please refer to Fig. 1-8, in the embodiment of the present invention, a kind of plastic extruder of automatic cycle switching cleaning strainer is special
Sign is: including operating room 1, hydraulic drive mechanism, wiper mechanism, pressure stabilizing mechanism；The hydraulic drive mechanism includes hydraulic cylinder 5
With hydraulic energy storage device 6, hydraulic cylinders bearing 7 is equipped on the downside of the hydraulic cylinder 5, hydraulic cylinders bearing 7 is detachably connected with support frame 4,
Support frame as described above 4 is equipped with sieve plate 3, and the sieve plate 3 is equipped with pushing plate 11, the pushing plate 11 and 5 piston nose of hydraulic cylinder
It is fixedly connected；The wiper mechanism includes cleaning smart nozzle 20, (operating) water nozzle 21, blowing mouth 2；The pressure stabilizing mechanism includes pressure control
Device 17 and surge chamber 2 processed.The sieve plate 3 is set there are four mounting hole, and mounting hole is interior to be equipped with ball.2 four wall of surge chamber is set
There is long and narrow fine crack, is equipped with wire 8, sealing ring 9 and ball 10 in fine crack.It is connected on the hydraulic cylinder 5 by hydraulic pipeline
Hydraulic energy storage device 6,5 piston of hydraulic cylinder pass through hydraulic cylinders bearing 7.The sieve plate 3 be equipped with pushing plate 11,11 liang of pushing plate
Side is equipped with idler wheel, and wire 8 passes through pushing plate 11, is fixed in sieve plate 3.Outside 8 outer surface of wire and the metal
The roughness of shell inner surface is no more than 0.1 micron.1 surface of operating room is equipped with the upper hermatic door 14 that can slightly open under
Hermatic door 15.The metal shell 18 is equipped with pouring orifice 19 at the both ends far from operating room 1.
Structure of the invention is novel, stable, in the use of the present invention, opening hydraulic energy storage device 6, and then can pass through a left side
Parallel metal shell 18 on left side pushing plate 11 is pushed into operating room 1 by the driving of side hydropress 5, will by upper side hydropress 5
Parallel metal shell 18 on upside pushing plate 11 is pushed into operating room 1, organizes across strainer；During push, steel wire
Line 8 only serves the effect of track, and wherein pressure plate 12 and horizontal pressure plate 13 are for fixing wire 8, and metal shell 18 rises
To reciprocal push switching effect；In order to guarantee the clear and coherent push of metal shell 18, during push, the oiling of metal shell 18
When mouth 19 is by lubrication hydraulic fluid port 23, lubricating oil can be all flowed by the way in metal shell 18 and wire 8, play lubricating action, often
All there is lubrication hydraulic fluid port 23 in 8 lower section of root wire；In addition the upper hermatic door 14 outside operating room 1 and lower hermatic door 15 closure, guarantee
