Be equipped with glass observation window 30 on the outer wall of screening case 2, glass observation window 30 highly is greater than the height of support frame 6, and the top of base 1 is equipped with roof 31, roof 31 is located the top of carriage 8, and the screening condition of the inside sand of screening case 2 can be observed in real time to glass observation window 30, can carry out the secondary screening to the sand that does not reach the production standard to make the screening process transparentization of sand, be favorable to improving screening efficiency, when meetting emergency in the screening process, the workman also can in time learn, the scram sieve separator, reduce the loss, the design of roof 31 is used for the sunshade or rain-proofly, play a guard action to carriage 8.
The working principle of the invention is as follows: when the screening work of the sand is carried out, the sand is firstly poured onto the screen mesh 11 in the screening inner part from the feeding port, and then the top cover 27 is covered by the handle, so that the sand is prevented from splashing when the screen mesh 11 operates.
After sand is poured into the screen mesh 11, the servo motor 20 is started through the controller 3, so as to drive the connecting rod 21 to rotate, because two ends of the connecting rod 21 are respectively hinged with the servo motor 20 and the inserted rod 22, one end of the inserted rod 22, which is far away from the connecting rod 21, is inserted into the screening box 2, so as to drive the inserted rod 22 to slide on the inner wall of the screening box 2, when the inserted rod 22 slides, because two ends of the supporting frame 6 are respectively inserted into the screening box 2 through two limiting rods 23, one end of the screening box 2, which is far away from the inserted rod 22, is inserted into the screening box 2 through a sliding rod 24, and because the outer walls of the inserted rod 22 and the sliding rod 24 are respectively sleeved with the telescopic springs 25, the outer wall of the supporting frame 6 and the inner wall of the screening box 2 are respectively abutted against two ends of each telescopic spring 25, so as to drive the supporting frame 6 to slide inside the screening box 2, the sliding and the shaking is realized, the two baffles 26 shield the gap between the support frame 6 and the inner wall of the screening box 2, so that sand is prevented from splashing during screening.
When the sand in the screen mesh 11 is screened, the sand meeting the production standard falls from the charging conduit to the bottom of the inner side of the screening box 2, and the bottom of the inner side of the screening box 2 is of a wedge-shaped structure, so that the sand meeting the production standard slides into the discharge port from the screening box 2, enters the feeding channel 28 through the discharge port, and is finally discharged from the feeding channel 28, and screening of the sand is completed.
But the screening condition of the inside sand of glass observation window 30 real-time observation screening case 2 can carry out the secondary screening to the sand that does not reach the production standard to make the screening process transparentization of sand, be favorable to improving the screening efficiency, when meetting emergency in the screening process, the workman also can in time learn, the scram sieve separator, reduce the loss, the design of roof 31 is used for the sunshade or is rain-proof, plays a guard action to carriage 8.
When screen cloth 11 needs to be replaced, the piece starts double-shaft cylinder 16 through controller 3, thereby make its output stretch out downwards, therefore drive second electric putter 17 and stretch out downwards, when stretching out to 19 highly uniform with the iron plate, start second electric putter 17 and electro-magnet 18 through controller 3, therefore the output that drives second electric putter 17 is close to the one end that is close to screen cloth 11, electro-magnet 18 and magnet attraction, and then drive screen cloth 11 and slide upwards carrying, when screen cloth 11 is close to a standing groove on carriage 8 that the one end of carriage 8 slides, through controller 3 outage electro-magnet 18, screen cloth 11 breaks away from with the output of second electric putter 17, start carriage 8 through controller 3 simultaneously, and then will be attracted screen cloth 11 and carry to the top of covering the standing groove completely.
After the inside screen cloth 11 of screening case 2 is taken out and is put a standing groove on carriage 8, start first electric putter 13 through controller 3, thereby make its output upwards stretch out, therefore it rises to drive carriage 8, when carriage 8 rises and drives another screen cloth 11 and reach corresponding height, start propelling movement subassembly 10 through controller 3, with the inside of another screen cloth 11 propelling movement to screening case 2, and then accomplish the change of screen cloth 11, when screen cloth 11 slides to screening case 2 inside from carriage 8, accept board 29 plays too big effect, and then make things convenient for screen cloth 11 to slide to pushing the mouth from carriage 8, two guide ways can guarantee that screen cloth 11's slip is steady.
Three standing groove is used for placing the not screen cloth 11 of three aperture equidimension, and the conveyer wheel makes things convenient for screen cloth 11's slip, dodges the breach and provides the decline space for propelling movement subassembly 10, and pulley 12 and spout cooperation make things convenient for screen cloth 11 to be carried to screening case 2 by carriage 8, and the aperture size in the filtration pore on three screen cloth 11 surface is different, satisfies the screening requirement of the sand of different production standards.
