In this embodiment, the oscillating unit is an oscillating motor 330, and the oscillating motor 330 drives the sieving block 120 to oscillate, so that the first sieving unit and the second sieving unit arranged in the sieving block 120 oscillate synchronously.
With the above embodiments, the usage principle and the working process of the present invention are as follows:
during operation, place the raw materials of mixing on first sieve 210, according to the degree of difficulty that the raw materials passes through first sieve 210, the raw materials diameter is far less than passing first sieve mesh 211 in advance of first sieve mesh 211 diameter, the raw materials that the diameter is less than first sieve mesh 211 diameter slightly passes first sieve mesh 211 along with the rotation of first sieve 210, make the raw materials that get into second sieve 230 and be close to inside and be the less raw materials of diameter, it is the raw materials that the diameter is slightly big that gets into second sieve 230 and be close to the outside, reduce the roll on second sieve 230 of the raw materials that the diameter is less than first sieve mesh 211 diameter slightly, further reduce the jam of the raw materials that the diameter is less than first sieve mesh 211 diameter slightly to second sieve 231.
The mixed raw materials are put into the first sieve plate 210 through the feeding pipe 130, the first sieve plate 210, the second sieve plate 230, the first guide plate 220 and the second guide plate 240 are driven to rotate anticlockwise by the rotating motor 320, and the oscillating motor 330 drives the first sieve plate 210, the second sieve plate 230, the first guide plate 220 and the second guide plate 240 to oscillate synchronously. In the rotating process of the first screen plate 210, the raw material is always at the lower end of the circumscribed circle of the cross section of the first screen plate 210, the first screen plate 210 rotates to enable the raw material to gradually pass through the side wall of the first screen plate 210, the raw material with the diameter far smaller than that of the first screen hole 211 rapidly passes through the first screen hole 211 when the first screen plate 210 just rotates, and the raw material falls on the first guide plate 220. Because the diameter of the circumscribed circle of the cross section of the first guide plate 220 gradually increases from left to right, and the distance between the first guide plate 220 and the first screen plate 210 gradually increases from left to right, the raw material gradually slides to right along the inclined plane of the lower end of the circumscribed circle of the cross section of the first guide plate 220, and gradually enters the second screen plate 230. The second screen openings 231 in the second screening deck 230 have a diameter smaller than the diameter of the first screen openings 211, and further screen the material screened on the first screening deck 210. As the first screening deck 210 rotates, material having a diameter slightly smaller than the diameter of the first screening holes 211 gradually passes through the first screening deck 210, material having a diameter slightly smaller than the diameter of the first screening holes 211 gradually enters the outside of the second screening deck 230 under the guiding action of the first guide plate 220, the material having a diameter slightly smaller than the diameter of the first screening holes 211 rolls on the second screening deck 230, and the blockage of the second screening holes 231 by the material having a diameter slightly smaller than the diameter of the first screening holes 211 is further reduced.
Part of the raw materials smaller than the diameter of the second sieve pore 231 pass through the second sieve pore 231 and then become qualified raw materials, the qualified raw materials are gradually discharged under the guiding action of the second guide plate 240, and the right end of the second guide plate 240 is communicated with the fourth notch, so that the qualified raw materials are accumulated at the fourth notch.
When the raw materials rolls on first sieve 210, partly irregular raw materials easily block up first sieve mesh 211, rotate to the first semicircle department of cross-section circumcircle at first sieve 210, the raw materials that block up first sieve mesh 211 under oscillating motor 330's effect, break away from gradually in first sieve mesh 211, make the raw materials fall on the second surface of first deflector 220, be provided with a plurality of striker plates on the second surface of first deflector 220, the striker plate hinders that the raw materials fall on the second surface of first deflector 220 and fall back again on first sieve 210, reduce irregular raw materials once more with the probability that first sieve 210 blockked up. At the upper half circle of the circumscribed circle of the cross-section of the first guide plate 220, the second surface of the first guide plate 220 is in a state of lower left end and higher right end, so that irregular raw materials are discharged from the left end of the first guide plate 220 along the second surface of the first guide plate 220. Part is less than the irregular raw materials of first sieve mesh 211 diameter, passes first sieve mesh 211, gets into on the second sieve 230 under the guide effect of first deflector 220, and part irregular raw materials blocks up second sieve mesh 231 once more, under the effect of oscillating motor 330, makes the raw materials fall on the second surface of second deflector 240 to under the effect of a plurality of striker plates that set up on the second surface of second deflector 240, hinder irregular raw materials to fall back once more to on the second sieve 230. At the upper half circle of the circumscribed circle of the cross section of the second guide plate 240, the second surface of the second guide plate 240 is in a state of low left end and high right end, so that irregular raw materials are discharged from the left end of the second guide plate 240 along the second surface of the second guide plate 240, enter the second surface of the first guide plate 220, and are discharged from the left end of the first guide plate 220 along the second surface of the first guide plate 220, the left end of the first guide plate 220 is communicated with the third notch 124 of the screening chamber, and the irregular raw materials are collected at the third notch 124.
Partial raw materials diameter is greater than first sieve mesh 211 diameter, and the great raw materials of diameter can't pass first sieve mesh 211, and the raw materials is piled up in the outer end of first sieve 210, and the fixed first hang plate 410 that is provided with in outer end of first sieve 210 makes the great raw materials of diameter discharge from the first discharge gate on the first hang plate 410 under the guide effect of first hang plate 410, and first discharge gate and first breach 122 intercommunication make the great raw materials of diameter pile up in first breach 122 department. The raw material partially smaller than the diameter of the first sieve hole 211 and larger than the diameter of the second sieve hole 231 is accumulated at the outer end of the second sieve plate 230 along with the rotation of the second sieve plate 230, and the raw material smaller than the diameter of the first sieve hole 211 and larger than the diameter of the second sieve hole 231 is discharged to the second notch 123 through the second discharge port of the second inclined plate 420 under the guiding action of the second inclined plate 420.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
