When people need to screen coarse and fine gravels, people can use the coarse and fine gravels classifying and screening equipment for the construction site, firstly people pour gravels onto the first filter screen 4, the first filter screen 4 filters the gravels, the coarse gravels are left on the first filter screen 4, the fine gravels fall down onto the second filter screen 41, then people press the first filter screen 4 downwards, the first filter screen 4 moves downwards to drive the first screening mechanism 5 to operate downwards, meanwhile, when the first filter screen 4 operates downwards, the first filter screen 4 moves downwards to drive the opening and closing mechanism 6 to operate downwards, the blanking frame 2 is opened, at the moment, people push the gravels on the first filter screen 4 backwards, the gravel flow in and out the material frame 21 flows backwards and downwards, people can collect the coarse gravels, then people loosen the first filter screen 4, and enable the first screening mechanism 5 to operate upwards, thereby drive first filter screen 4 upward movement, thereby drive the mechanism 6 that opens and shuts and upwards function, and then close unloading frame 2, make the grit that presss from both sides on first filter screen 4 down, because the gravity of grit, so can drive second filter screen 41 slight downswing, and then drive second screening mechanism 7 downward operation, second filter screen 41 filters the grit once more this moment, make second filter screen 41 screen thinner grit, thicker grit falls into the rear side of collecting frame 3, thinner grit continues down, and then falls at the front side of collecting frame 3, when the grit falls into completely in collecting frame 3, second filter screen 41 does not exert pressure to second screening mechanism 7, make second screening mechanism 7 upwards operate and reset, and then drive second filter screen 41 slight upswing.
When people fall into grit on first filter screen 4, at first people press down first filter screen 4, thereby drive crane 51 and the equal downstream of first torsion spring 53, thereby it supports little iron stand 54 and the equal downstream of first filter screen 4 to drive, first spring 52 is compressed, people loosen first filter screen 4 afterwards, because first spring 52, so can drive crane 51 and the equal upstream of first torsion spring 53 and reset, and then drive and support little iron stand 54 and the equal upstream of first filter screen 4 and reset, and then reached the effect of shaking first filter screen 4, prevent to press from both sides the grit on first filter screen 4.
When first filter screen 4 downstream, first filter screen 4 drives pressurized groove 62 downstream, thereby drive switching device 61 downstream, second spring 63 is compressed, unloading frame 2 is opened, people can promote thick grit backward this moment, and then on flowing in and out material frame 21, and then make things convenient for people to collect thick grit, ejection of compact effect has then been realized, when first filter screen 4 upward movement, because second spring 63 resets, so can drive switching device 61 and the equal upward movement of first filter screen 4 and reset, and then drive pressurized groove 62 upward movement and reset, unloading frame 2 is closed.
When the sand is primarily screened, the primarily screened sand falls on the second filter screen 41 through the inclined block in the blanking frame 2, the second filter screen 41 is driven to slightly swing downwards due to the gravity of the sand, so that the fixed frame 71 and the long rod frame 74 are driven to move downwards, the rotating shaft 72 is driven to rotate, the second torsion spring 73 is deformed, the second filter screen 41 screens the sand again, the thicker sand falls backwards and downwards through the second filter screen 41, the thinner sand continues to fall downwards, the thicker sand falls on the rear side of the collecting frame 3, the thinner sand falls on the front side of the collecting frame 3, the thinner sand is screened through the second filter screen 41, after the sand is screened, the rotating shaft 72 is driven to rotate due to the reset of the second torsion spring 73, and the fixed frame 71 and the long rod frame 74 are driven to move upwards and reset, thereby driving the first filter screen 4 to swing upwards slightly and reset.
When people push the first filter screen 4 downwards, the first filter screen 4 moves downwards to drive the connecting frame 91 to move forwards and downwards, the third spring 93 is compressed to drive the sliding ring sleeve 94, the second supporting sliding rod 95 and the fourth spring 96 to move downwards to drive the lug 97 to move downwards to drive the long rod frame 74 to move downwards to drive the rear side of the second filter screen 41 to swing downwards, the first torsion spring 53 deforms to enable the second filter screen 41 to be in an inclined state, coarse gravels automatically flow backwards and downwards, and when people loosen the first filter screen 4, the third spring 93 and the first torsion spring 53 are reset to drive the connecting frame 91 to move upwards to drive the rear side of the first filter screen 4 to swing upwards to reset to drive the connecting frame 91 to move upwards to reset, and then the sliding ring sleeve 94, the second supporting sliding rod 95 and the second supporting sliding rod 95 are driven to move upwards, The fourth spring 96 and the bump 97 both move upwards, the bump 97 loosens the long rod frame 74, and the second filter screen 41 moves upwards to reset at the moment, so that the long rod frame 74 is driven to move upwards, and then the effect of driving the second filter screen 41 to shake violently is achieved.
One can push the pusher 81 backward to move the fixed slider 82 backward, so that the fixed slider 82 releases the shaking frame 102, the sixth spring 103 in a compressed state is restored, so as to drive the shaking frame 102 to move downwards for resetting, and further drive the first filter screen 4 to move downwards, as one continues to push the pusher 81 rearward, the fifth spring 84 is compressed, the fixed slider 82 abuts against the shaking frame 102, the sixth spring 103 is compressed, thereby driving the first filter screen 4 to move upwards, further facilitating the effect of shaking the first filter screen 4, when one cannot push the pusher 81 to move backward, one releases the pusher 81, and, since the fifth spring 84 is restored, the slider is driven to move forward to reset, and then the pusher 81 is driven to move forward to reset, so that the effect of automatically shaking the first filter screen 4 again is realized.
When the fixed slider 82 moves backwards, the fixed slider 82 drives the first reel 112 to move backwards, so that the winding rope 113 is pulled to drive the fixed rotating wheel 111 to rotate, so that the second reel 114 is driven to rotate, and further the projection 97 is driven to rotate forwards and downwards and move forwards and downwards, the fourth spring 96 is compressed, when the projection 97 rotates, the projection 97 drives the long rod frame 74 to move downwards, so that the second filter screen 41 is driven to move downwards, when the projection 97 continues to rotate, the projection 97 is not in contact with the long rod frame 74, the second filter screen 41 moves upwards to drive the long rod frame 74 to move upwards to reset, so that the effect of enabling people to intermittently shake the second filter screen 41 is realized, when the fixed slider 82 continues to move backwards, the fixed slider 82 drives the first reel 112 to continue to move backwards, so that the winding rope 113 is pulled to drive the second reel 114 to continue to rotate, thereby drive second reel 114 and lug 97 and continue to rotate and to the motion of forward below, slip ring cover 94 blocks second reel 114 this moment, make second reel 114 can't continue downstream, and then drive slip ring cover 94 and join the equal downstream of frame 91, and then reached and driven first filter screen 4 front side down-swing's effect, and then reduced manual operation, when fixed slider 82 moved forward and reset, fixed slider 82 drove first reel 112 forward motion, thereby drive fixed runner 111 reversal pulling wire winding rope 113, thereby drive second reel 114 and lug 97 all reversal, and then drive second filter screen 41 shake through long pole frame 74 once more, simultaneously because fourth spring 96 resets, so can drive second reel 114 and lug 97 all upwards backward motion and reset.
