when in use, firstly, materials can be put in through the blanking groove 201, so that the materials can be subjected to the next screening process, the materials needing secondary screening can be transmitted through the qualified blanking pipe 202, screening is carried out through the screening component 3, then, the qualified aggregates are transmitted to the machine box in the left collecting box 215 to be collected for use, the vibrating plate 304 can be driven to vibrate through the vibrating motor 302, screening is carried out through the fine net 305 and the coarse net 306 and are respectively transmitted, the primarily screened coarse aggregates can be transmitted through the inferior blanking pipe 203, the primarily screened aggregates can be directly collected in the right collecting box 215, the qualified blanking pipe 202 and the connecting pipe 212 can be movably connected through the connecting ring 209, the spring 211 is fixedly connected between the upper limiting disc 210 and the lower limiting disc 210, so that the screening component 3 can carry out shock absorption operation when vibrating, the service life of the reinforcing part is prolonged, qualified aggregates can be transmitted and screened through the fine net 305 and then transmitted to the left collecting box 215 for collection, unqualified aggregates can be transmitted and screened through the coarse net 306 and then transmitted to the right collecting box 215 for collection, and the fine net 305 and the coarse net 306 are fixed through the screws 208, so that the screening of aggregates of other specifications can be realized only by replacing the fine net 305 and the coarse net 306.

It should be noted that the specific model specification of the vibration motor 302 is YBZ-110L2-2, and the specific model selection calculation method adopts the prior art in the field, so detailed description is omitted.

The foregoing shows and describes the general principles and broad features of the present invention and advantages thereof. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are described in the specification and illustrated only to illustrate the principle of the present invention, but that various changes and modifications may be made therein without departing from the spirit and scope of the present invention, which fall within the scope of the invention as claimed. The scope of the invention is defined by the appended claims and equivalents thereof.
