14-1-1 or hook 14-1-3, then moves the other end and takes current limiting plate 14-1 again, the lower ends mobile remaining current limiting plate 14-1
Hook so that bottom baffle 14-2 is taken off, and then reach current-limiting apparatus 14 and the inside of feeding cylinder 1 be connected to, remove bottom as needed and keep off
The current limiting plate 14-1 of plate 14-2 and different number can adjust the flow velocity of sand；Charging is flowed by the sand of current-limiting apparatus 14
Inside cylinder 1, part sand passes through pre-sifted screening device 2, and screening is directly entered by runner 10-4 by the sand of pre-sifted screening device 2
II 9 upper end of device, another part sand enter screening plant III 10 by the gap between feeding cylinder 1 and pre-sifted screening device 2
Upper end makes part sand screen in advance, saves screening time, promotes screening efficiency, then starts motor 17,17 band of motor
Turn axis 18 rotates and then turntable 13 is driven to rotate, and turntable 13 drives an end motion of drive link 11, the other end of drive link 11
It is slided in II 4-7 of through-hole while slide plate II 12 being driven to be slided along II 4-6 of slideway, slide plate II 12 is driven by side shield 19 and slided
Plate I 5 slides, and slide plate I 5, slide plate II 12 drive screening plant I 8, screening plant II 9, screening plant III 10 to move, and make the upper end
Sand by sieve complete screening operation, when need the sand after screening is collected respectively when, by screening plant I 8
Sand is collected by II 4-8 of sediment ejection opening, when needing to collect the sand on screening plant II 9, by barrier plate 6-3-1 along arc
Slot 6-4 movements, make the triangle groove 6-5 of its top and top coordinate, are then fixed by fastening nut 6-3-3, screening dress
The sand for setting II 9 upper ends enters by II 5-4 of rectangular opening inside tapping channel 6-1, then collects, and is screened when needing to collect
When sand on device III 10, barrier plate 6-3-1 is moved along arc groove 6-4, makes the triangle groove 6-5 of its top and lower section
Cooperation, is then fixed by fastening nut 6-3-3, the sand of III 10 upper end of screening plant enters discharging by I 5-2 of rectangular opening
Inside the 6-1 of channel, then collect.
Certainly, above description is not limitation of the present invention, and the present invention is also not limited to the example above, the art
The variations, modifications, additions or substitutions that those of ordinary skill is made in the essential scope of the present invention also belong to the guarantor of the present invention
Protect range.
