Based on the above, the airflow entering the dust cover 21 through the blower 22 is ejected toward the conveyer belt 31 through the air outlet 214, and the airflow can effectively inhibit the dust on the conveyer belt 31 from spreading upwards, so that the dust can be greatly reduced from attaching to the glass plates on the top and the side wall of the concave structure 211, and the dust is prevented from affecting the definition of the photo.

In addition, under the effect of air-blower 22, the internal pressure of cover is greater than the external pressure of cover, and then can effectively prevent external dust to get into the protection casing and on adhering to the equipment of shooing body 10, and then can improve the result of use and the life-span of the equipment of shooing body 10.

As shown in fig. 5, the utility model further discloses a screening machine, which includes a conveying platform 30 and the above-mentioned photographing recognition mechanism located above the conveying platform 30, wherein a dust cover 21 in a dust-proof system 20 in the photographing recognition mechanism is covered outside the photographing apparatus body 10, and under the action of an air blower 22 of the dust-proof system 20, the bottom of the dust cover 21 sprays air flow to prevent dust on the conveying belt 31 from diffusing to the dust cover 21, so that the dust can be effectively prevented from shielding the photographing path of the photographing apparatus body 10.

The photographing identification mechanism provided by the utility model has the advantages that:

1. through addding dustproof system 20 to make the air current spout from the bottom of dust cover 21, and then can effectively avoid the dust to shelter from the shooting route of the equipment body 10 of shooing, improved the effect of shooing.

2. Atmospheric pressure in the dust cover 21 is greater than external atmospheric pressure, and then can effectively avoid the dust to enter into the dust cover 21, avoids the dust to fall into the equipment body 10 of shooing, has improved the result of use and the life-span of the equipment body 10 of shooing.
