Specifically, the first sieve plate 23, the second sieve plate 25 and the third sieve plate 27 are all connected with the adjacent crushing plates 18 in a sliding manner, and the size of the third sieve hole 28 is the size of finished sand, so that the first sieve plate 23, the second sieve plate 25 and the third sieve plate 27 can perform high-frequency vibration inside the adjacent crushing plates 18 by virtue of the combined action of the gravity of top sand and bottom airflow, and thus sand to be shaped is sieved; since the third screen aperture 28 is sized to the size of the finished sand, the sand screened along the third screen aperture 28 can flow directly into the finished chamber 6 for collection.

When the sand-rock separating device is used, sand to be screened is poured into the sand-rock separating device along the feeding hopper 35, part of the sand-rock enters the material throwing feeding hole 31 along the feeding hopper 35 and reaches the top of the third sieve plate 27 along the material throwing feeding hole 31, and meanwhile, the controller 21 controls the opening size of the regulator 32, so that the other part of the sand is pushed away from the side baffle 33 to enter the shaping feeding hole 34 and enters the shaping cavity 36 along the shaping feeding hole 34.

The grit size that is located third sieve 27 top can fall to second sieve 25 top along third sieve 28 when being less than third sieve 28, and the grit size can be thrown away along discharge gate 19 under the effect of centrifugal force and get into whole shape intracavity portion 36 when being greater than third sieve 28, the grit of throwing away can collide the broken resilience with the grit in week backplate 6 or whole shape intracavity portion 36, the grit after kick-backing collides the breakage board 18 at branch charging tray 17 top or the grit of throwing away at discharge gate 19 and is broken, because this part grit is located whole shape intracavity portion 36 higher position, consequently carry out the broken plastic of collision that relapse many times in whole shape intracavity portion 36, thereby improve plastic effect.

If the size of the sand located at the top of the second sieve plate 25 is smaller than that of the second sieve hole 26, the sand can fall to the top of the first sieve plate 24 along the second sieve hole 26, the sand with the size larger than that of the second sieve hole 26 can be thrown out along the discharge hole 19 under the action of centrifugal force, the thrown sand is collided and crushed and shaped in the shaping cavity 36, but the part of sand is lower than the sand at the top of the third sieve plate 27 due to the throwing-out position, and the size of the part of sand is smaller than that of the sand at the top of the third sieve plate 27, so the number of times of rebound shaping in the shaping cavity 36 is relatively small, and the sand can be collected in the finished product cavity 6 after shaping can be completed more quickly.

If the size of the sand on the top of the first sieve plate 23 is smaller than that of the first sieve hole 24, the sand can directly fall into the finished product cavity 6 along the first sieve hole 24, and the sand with the size larger than that of the first sieve hole 24 can also be thrown out along the discharge hole 19 for collision crushing and shaping, and the sand at the position is the lowest and the size is the smallest, so that the sand can directly enter the finished product cavity 6 along the shaping cavity 36 for collection after collision crushing and shaping for a few times.

Simultaneously, can drive convulsions fan blade 9 when main shaft 12 rotates and rotate, convulsions fan blade 9 rotates and can extract outside air and get into the intracavity portion of bleeding, the elasticity connection piece 20 of 8 surfaces of bleeding constantly expands along with the gas volume in the chamber 8 that bleeds and constantly takes place to expand, elasticity connection piece 20 constantly expands and can extrude finished product chamber 6, make the grit finished product in finished product chamber 6 can directly not fall to the bottom and collect, and the grit finished product that the flow received the hindrance will be with the abundant frictional contact of filter screen at impurity chamber 7 top, improve the screening efficiency of filter screen, guarantee that the filter screen can carry out abundant thorough edulcoration to the grit finished product.

Along with the continuous rotation of the air exhaust fan blade 9, the gas content in the air exhaust cavity 8 is continuously increased, and along with the continuous feeding of the feed hopper 35, the gravels on the tops of the first sieve plate 23, the second sieve plate 25 and the third sieve plate 27 positioned on the top of the buffer spring 22 are continuously increased, the reaction force of the bottom of the buffer spring 22 on the material distribution plate 17 is also continuously increased, when the pressure value detected by the pressure sensor on the top of the material distribution plate 17 is greater than the set pressure threshold value, the controller 21 controls the electromagnetic one-way valve 30 to open, the gas in the air exhaust cavity 8 enters the finished product cavity 6 along the electromagnetic one-way valve 30, the gas can blow the gravel finished product in the finished product cavity 6 to move to the impurity cavity 7 end, and the volume of the elastic connecting sheet 20 is reduced when the gas in the air exhaust cavity 8 is reduced, so the elastic connecting sheet 20 relieves the obstruction to the flow of the gravel finished product, the gravel in the finished product cavity 6 is fully contacted with the filter screen and extruded and rubbed under the combined action of gravity and wind power, thereby make the grit finished product in the finished product chamber 6 carry out abundant edulcoration, impurity is retrieved in getting into impurity chamber 7 along the filter screen, and clear grit falls to the 6 bottoms in finished product chamber and collects, and gaseous edge finished product chamber 6 blows upwards simultaneously, can blow the impurity dust that produces in shaping chamber 36 and the feeder hopper 35 is reverse to discharge along feeder hopper 35, thereby reduce the off-the-shelf impurity content of grit.

Meanwhile, the airflow can reach the bottom of the outer side of the first sieve plate 23 upwards, the first sieve plate 23 can move upwards under the thrust action of the airflow, the first sieve plate 23 can drive the second sieve plate 25 and the third sieve plate 27 to move upwards synchronously when moving upwards, meanwhile, because the sand content of the central positions of the first sieve plate 23, the second sieve plate 25 and the third sieve plate 27 is high, and the airflow mainly acts on the outer side of the first sieve plate 23, the second sieve plate 25 and the third sieve plate 27 can incline from the two side positions to the middle position when moving upwards, sand on the tops of the first sieve plate 23, the second sieve plate 25 and the third sieve plate 27 can be fully in squeezing contact with the sand when moving, and therefore the sand can be screened efficiently by means of the first sieve holes 24, the second sieve holes 26 and the third sieve holes 28.

When the first sieve plate 23 moves upwards under the action of bottom airflow, the extrusion force on the top of the buffer spring 22 is reduced, the pressure of the buffer spring 22 on the sub-material distribution disc 17 is reduced, the pressure value detected by the pressure sensor is lower than a set threshold value, the controller 21 controls the electromagnetic one-way valve 30 to be closed, the main shaft 12 rotates to continuously drive the air draft fan blade 9 to rotate to pump air into the air draft cavity 8, the first sieve plate 23 can extrude the buffer spring 22 downwards again under the action of the gravity of top sand and the air of the air draft cavity 8 due to the loss of the airflow on the bottom of the first sieve plate 23, so that the first sieve plate 23, the second sieve plate 25 and the third sieve plate 27 can continuously vibrate at the top of the sub-material distribution disc 17 at high frequency under the combined action of the gravity of the sand and the air exhausted from the air draft cavity 8, thereby increasing the sieving efficiency and ensuring the sieving effect, and the sand finished product in the finished product cavity 6 can also be subjected to high-frequency exhaust and impurity removal from the cavity 8, effectively improves the removal of impurities in the finished sandstone product and improves the tidiness of the finished sandstone product.
