[0024] The beneficial effect of this improvement is that the driving motor drives the conveying roller to rotate through the worm gear reducer, and the rotation of the conveying roller drives the conveyor belt to transport the material to the top of the collecting hopper.
[0025] The beneficial effects of the utility model are as follows: when the material enters the interior of the collecting hopper, the material hits the sponge cushion layer, the sponge cushion layer is compressed and shrinks, and the pressure is transmitted to the mounting plate and the rubber sound-absorbing layer, absorbing the vibration of the material and reducing the noise when the material hits the sponge cushion layer. For the collision noise between the materials, the collecting hopper cooperates with the sound insulation cotton to isolate the noise;

After the material enters the inside of the device frame, the heavier dust falls. The air is decelerated by the deceleration plate and then discharged through the exhaust pipe installed on the ash collecting chamber to remove dust from the inside of the device. This method can reduce dust pollution when the device is in use. BRIEF DESCRIPTION OF THE DRAWINGS

When the material enters the interior of the collecting hopper 3, the material hits the sponge cushion layer 34, and the sponge cushion layer 34 is compressed and shrinks, and the pressure is transmitted to the mounting plate 33 and the rubber sound-absorbing layer 32, so as to absorb the vibration of the material and reduce the noise when the material hits the sponge cushion layer 34. For the collision noise between materials, the collecting hopper 3 cooperates with the sound insulation cotton 31 to isolate the noise. During the sorting process, the exhaust fan 53 extracts the dust inside the collecting hopper 3 to the interior of the ash collecting chamber 5 through the dust removal duct 54 and the dust collecting plate 55. After the material enters the interior of the device frame 1, the heavier dust falls, and the air is decelerated by the deceleration plate 51 and then discharged through the exhaust duct installed on the ash collecting chamber 5. The inside of the device can be dusted, and this method can reduce dust pollution when the device is used. There are two rubber sound-absorbing layers 32, and the inner side of the rubber sound-absorbing layer 32 is inclined. The two rubber sound-absorbing layers 32 can cooperate with the mounting plate 33 and the sponge pad 34 to reduce the potential energy of the material sorted into the collection hopper 3, and reduce the noise when the material collides with the sponge pad 34. The inclined rubber sound-absorbing layer 32 can cooperate with the sponge pad 34 to facilitate the material to reach the top of the belt conveyor 4.

When the material is separated from the collecting hopper 3, the air pump 2 conveys compressed air to the position of the blowing rod 21, and the compressed air blows up the lighter material and throws it into the side of the collecting hopper 3 away from the device frame 1, and the heavier material directly falls into the inside of the collecting hopper 3 close to the device frame 1. When the material enters the inside of the collecting hopper 3, the material hits the sponge cushion layer 34, and the sponge cushion layer 34 is compressed and shrinks, and the pressure is transmitted to the mounting plate 33 and the rubber sound-absorbing layer 32 to absorb the vibration of the material. The noise generated when the material collides with the sponge cushion layer 34 is reduced. For the collision noise between the materials, the collecting hopper 3 cooperates with the sound insulation cotton 31 to isolate the noise. Then the material passes through the discharge baffle 35 to the top of the belt conveyor 4. At this time, the belt conveyor 4 transports the sorted material to complete the sorting of the material. During the sorting process, the exhaust fan 53 extracts the dust inside the collecting hopper 3 to the inside of the ash collecting chamber 5 through the dust removal pipe 54 and the dust collecting plate 55. After the material enters the inside of the device frame 1, the heavier dust falls. After the air is decelerated by the deceleration plate 51, it is discharged through the exhaust pipe installed on the ash collecting chamber 5 to remove dust from the inside of the device.
