Further in order to avoid the condition that ore has initial velocity and folding on the second conveyer belt 3, be equipped with the fender curtain 33 in the exit that keeps off material shell 4, the fender curtain 33 downside is equipped with separating groove 34, interval between two separating grooves 34 is the same with interval between two shelves levers 30, also for the maximum interval of inspection ore, the bottom of rolling up the curtain is slightly higher than second conveyer belt 3, the ore can all contact with the rolling up curtain when rolling up the curtain, the ore is when advancing the rolling up curtain, can make rolling up curtain part deformation under the drive of second conveyer belt 3, thereby make the ore pass through, the partial tiny particle ore that stacks together also can separate under the effect of rolling up the curtain, the rolling up curtain also plays the effect of blockking to the removal of ore simultaneously, ensure that the speed of ore is unanimous with the speed of second conveyer belt 3, improve efficiency and the accuracy of follow-up detection.
The guard plate 35 plays the guard action to the ray emitter 5, avoids dropping to the ore from the upside and causes the damage to the ray emitter 5 most, and electromagnetic air injection valve 6 is installed in box 36, and the box 36 upside is the inclined plane, and the inclined plane of box 36 is tangent with the curved surface of second conveyer belt 3, and the ore is fallen behind by inertia from second conveyer belt 3, and the venthole can be better jet air to the ore, ensures the separation work of ore.
The front side of the bin cover 37 is provided with an opening, and the upper side of the bin cover 37 is provided with a sealing structure, so that ore overflowed by the air outlet hole can be avoided, and the ore can be better collected.
The whole working flow of the invention is as follows: the feeding equipment of ore is connected to one end of first conveyer belt 2, first conveyer belt 2 transports the ore to buffer gear, vibrations sieve 10 slows down the travel speed of ore, leak the less stone dust of granule simultaneously from vibrations sieve 10's sieve mesh, the ore that rolls down from vibrations sieve 10 falls to second conveyer belt 3, the feed mechanism of second conveyer belt 3 upside will overlap together the ore and carry out tiling, the ore distributes on second conveyer belt 3, the ore after the dispersion shines the screening through ray emitter 5, afterwards electromagnetic blast valve 6 judges whether need jet through the feedback of ray emitter 5, the ore that need not jet drops into the front side cavity of ore storehouse 7 under the inertia of second conveyer belt 3 drive, it is to need jet, the ore rises whereabouts orbit under the effect of electromagnetic blast valve 6 to drop in the rear side cavity of ore storehouse 7 to judge, it is to need jet, ore drops in the rear side cavity of ore storehouse 7 to be qualified for the fact
Finally, it should be noted that: the foregoing description is only illustrative of the preferred embodiments of the present invention, and although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described, or equivalents may be substituted for elements thereof, and any modifications, equivalents, improvements or changes may be made without departing from the spirit and principles of the present invention.
