[0031] See also Figure 3 , Figure 4 and Figure 5The inner wall of the gravity screening box 2 is provided with a fan blade 206, and both ends of the fan blade 206 are rotatably connected to the screening body 1. A pulley is fixed to the front end of the fan blade 206 and is connected to the first motor 101 through a belt. The first motor 101 drives the fan blade 206 to rotate. The rotation of the fan blade 206 generates wind force, which blows up the material on the upper end of the gravity screening box 2, separates the lighter material from the heavier material, and then realizes the screening of the material. The inner wall of the gravity screening box 2 is connected with a screening plate 204, and the upper end of the screening plate 204 is provided with a plurality of fish scale holes 2042 and through holes 2043 along its short side, and the upper end of the screening plate 204 is fixed with a plurality of long anti-roll bars 2041 along its long side.

Since the material in the feed hopper 105 continues to fall, the suspended material will not be discharged through the feed hopper 105, and the heavier material will fall back to the upper end of the screening plate 204. The heavier material is prevented from rolling by the anti-roll bar 2041. At the same time, in the process of the gravity screening box 2 reciprocatingly swinging and the material repeatedly rising and falling, the anti-roll bar 2041 will move the heavier material to the first discharge port 3, and finally the heavier material is discharged from the first discharge port 3. 4 is provided with a top plate 205 at the lower end, the top plate 205 is fixedly connected to the gravity screening box 2, a plurality of guide holes 2051 are opened along the short side of the top end of the top plate 205, a plurality of cylindrical anti-blocking columns 2052 are fixed to the upper end of the top plate 205, the anti-blocking columns 2052 correspond to the through holes 2043 one by one, the upper ends of the anti-blocking columns 2052 are rounded, the anti-blocking columns 2052 on the top plate 205 correspond to the through holes 2043 one by one, when the screening plate 204 is subjected to the downward movement of the material, the anti-blocking columns 2052 will be inserted into the through holes 2043 to push out the material stuck in the through holes 2043, to prevent the material from being blocked, to affect the screening effect of the material, and to guide the flow through the guide holes 2051, so that the fan blade 206 produces The wind force is evenly blown out from the fish scale holes 2042 and the through holes 2043. The upper end of the anti-blocking column 2052 is rounded to facilitate the anti-blocking column 2052 to be quickly inserted into the conducting hole 2043. The left and right sides of the lower end of the top plate 205 are respectively provided with fixing plates 207, and the fixing plates 207 are fixed on the gravity screening box 2. A plurality of circular holes are provided on the surface of the fixing plate 207. By providing circular holes on the fixing plate 207, the fixing plate 207 is prevented from affecting the wind force generated by the fan blades 206. A plurality of springs 208 are fixed to the upper end of the fixing plate 207 along its long side. The upper end of the spring 208 passes through the top plate 205 and is fixedly connected to the lower end of the screening plate 204, and the screening plate 204 is connected through the spring 208.It is beneficial for the screening plate 204 to be compressed after being subjected to the gravity of the material, and the screening plate 204 is restored to drive the screening plate 204 to move upward so that the material on the upper end of the screening plate 204 is lifted up again, and the material is blown up and screened, thereby improving the screening efficiency.

[0032] When the utility model is used:

[0033] First, the material to be screened is poured into the feed hopper 105, and the first motor 101 and the second motor 102 are powered on to work. The first motor 101 works and drives the fan blade 206 to rotate through the belt. The fan blade 206 rotates to generate wind force. The second motor 102 works and drives the first connecting rod 201 to rotate through the belt. The first connecting rod 201 drives the gravity screening box 2 to swing back and forth counterclockwise.

[0034] Then, pull the adjustment handle 107 to move the adjustment plate 106, the feed hopper 105 opens, and the material falls evenly onto the upper end of the screening plate 204;

[0035] Next, the gravity screening box 2 repeatedly swings to lift the material on the upper end of the screening plate 204, and the wind generated by the fan blade 206 is diverted through the guide hole 2051 of the top plate 205. The diverted wind blows up the material on the upper end of the screening plate 204 through the through hole 2043, and the lighter material is suspended, and the fish scale hole 2042 blows out the wind generated by the fan blade 206 obliquely, and the suspended material is discharged from the second discharge port 4. Since the material in the feed hopper 105 continues to fall, the suspended material will not be discharged through the feed hopper 105, and the heavier material will fall back to the upper end of the screening plate 204. The heavier material is prevented from rolling by the anti-roll bar 2041, and at the same time, the gravity screening box 2 swings back and forth, and the material is repeatedly lifted up During the falling process, the anti-roll bar 2041 will move the heavier material to the first discharge port 3, and finally the heavier material will be discharged from the first discharge port 3. After the heavier material passes through the screening plate 204 from the air, the spring 208 will be compressed by the gravity of the heavier material. The compression of the spring 208 will cause the screening plate 204 to fall. At this time, the anti-blocking column 2052 will be inserted into the through hole 2043 to push out the material stuck in the through hole 2043 to prevent the material from being blocked and affecting the screening effect of the material. The spring 208 needs to be restored after being compressed. When the spring 208 is restored, the screening plate 204 will be bounced up, so that the material on the upper end of the screening plate 204 will continue to be lifted up for screening, thereby ensuring the efficiency of material screening.

[0036] Finally, according to the different material screening, the rotation speed of the first motor 101 is adjusted, and then the wind force generated by the fan blade 206 is adjusted to achieve different screening effects for different materials. The lighter materials are discharged from the second discharge port 4, and the heavier materials are discharged from the first discharge port 3.
