Specifically, when the conveying roller 20 is driven by the motor 22 to rotate, the conveying roller 20 drives the sieving assembly 5 to move together, the sieving assembly 5 performs sieving processing on molybdenum ores, so that molybdenum ores with particle sizes of 10-35mm are classified into different sizes again, for example, from one end to the other end, the sizes of the discharging pipelines 240 are sequentially increased, molybdenum ores with different particle sizes can enter the discharging pipelines 240 with different radial sizes, then the molybdenum ores with particle sizes enter the corresponding material placing grooves 210, the sizes of the material placing grooves 210 are set according to the particle sizes of the molybdenum ores entering the different discharging pipelines 240, so that each material placing groove 210 basically takes away only one molybdenum ore when passing through the lower end of the discharging pipeline 240, the molybdenum ores are prevented from being stacked together, the penetrating effect of X-ray penetration is influenced, the detection data are wrong, the separating effect of molybdenum ore particles with high molybdenum content and molybdenum content is poor, and each spraying gun 31 can aim at only one molybdenum ore at each time for separation of a group of the molybdenum ores 210, and the sorting accuracy of the molybdenum ore particles can be effectively improved.

Preferably, sieve material subassembly 5 includes carousel 50, and the conveying roller 20 other end that is equipped with motor 22 is equipped with carousel 50, it is equipped with sieve 51 to arrange material 24 upper surface slip, the slip orbit of sieve 51 on arranging material 24 is circular arc structure, it has connecting rod 52 to articulate jointly between the position of the centre of a circle and the sieve 51 of carousel 50, the mesh on the sieve 51 is equallyd divide into a plurality of groups along its length direction, and every group puts silo 210 and every group's mesh one-to-one, sieve 51 middle height is less than both ends height, and the size of mesh increases from the both ends of sieve 51 toward the centre in proper order, and the size of putting silo 210 and the size of arranging material pipeline 240 increase thereupon.

Specifically, the conveying roller 20 can drive the rotary disc 50 to synchronously rotate when rotating, if the conveying roller and the rotary disc 50 are coaxially and fixedly connected, because the connecting rod 52 is connected with the position of the rotary disc 50 deviating from the center of the circle, when the rotary disc 50 rotates, the connecting rod 52 can be pulled and pushed, so that the connecting rod 52 can pull the sieve plate 51 to reciprocate on the discharging part 24, the sieve plate 51 can sieve the molybdenum ore falling from the storage box 23, the molybdenum ore of different grain grades can roll down in meshes of different sizes while being sieved, and the molybdenum ore of 10-35mm grain grades can be graded again.

Furthermore, a slide 53 is formed in the turntable 50, a slide 54 is slidably disposed in the slide 53, the position of the slide 54 is always deviated from the center of the turntable 50, the connecting rod 52 is hinged to the slide 54, an electric push rod 55 is disposed in the slide 53, and an output end of the electric push rod 55 is connected to the slide 54.

Specifically, because molybdenum ore particle grades are different, the problem of material blocking driving in the mesh holes can occur, when no molybdenum ore particles exist in the material placing groove 210, the existence of molybdenum ore can not be detected by the X-ray at the emitting position of the X-ray emitter, so that the signal can be transmitted to the electric push rod 55 by the X-ray emitter, the electric push rod 55 extends, the distance from the sliding block 54 to the center of the rotary disc 50 is increased, then, when the rotary disc 50 rotates, the distance for pulling or pushing the connecting rod 52 is increased, the amplitude for driving the sieve plate 51 to do reciprocating motion by the connecting rod 52 is increased, the sieving amplitude of the sieve plate 51 is increased, the height drop of the molybdenum ore particles which are sieved each time is increased, the impact force among the molybdenum ores can be increased accordingly, the molybdenum ore particles which are not blocked in the mesh holes can impact blocked molybdenum ore particles with higher force, and the probability of material blocking in the mesh holes is reduced, thereby improving the efficiency of molybdenum ore dressing. By extending and shortening the electric push rod 55, the movement amplitude of the sieve plate 51 is changed and the slight vibration caused by the change is realized, so that a certain blockage removing effect is realized. Simultaneously, can also respond to the supplied materials of different weight through electric putter 55's extension and shortening, when sieve material subassembly 5 material is more, increase or reduction swing range that can correspond in order to promote sieve material efficiency, equally, when sieve material subassembly 5 material is more, increase or reduction swing range that also can correspond.

Specifically, because a certain time is needed when the X-ray emitter emits X-rays to penetrate through molybdenum ore, the motion speed of the material conveying belt 21 is relatively slow, when the material conveying belt 21 is slow in motion speed to throw the detected molybdenum ore, the throwing distance of the molybdenum ore is relatively short, so that the flat throwing motion track of the molybdenum ore is shortened, the time for the air-jet electromagnetic valve 30 to drive the spray gun 31 to jet and blow the molybdenum ore is required to be faster, but the sorting effect on the molybdenum ore particles is reduced, the material throwing belt 60 is added, when the conveying roller 20 rotates, the rack 68 can be driven by the first gear 66 to move towards the motor 22, so that the second spring is compressed to store force, the rack 68 can simultaneously drive the second gear 67 to rotate, the second gear 67 drives the material throwing roller 61 to rotate, and due to the action of the material blocking plate, when the material throwing belt 60 drives the impact block 63 to be far away from molybdenum ore particles, the molybdenum ore particles can be prevented from moving along with the material throwing belt 60, the number of teeth of the first gear 66 is correspondingly set according to the distance between the material placing grooves 210 on the material conveying belt 21, so that only one molybdenum ore falling into one material throwing channel 62 is obtained, after the first gear 66 is not meshed with the rack 68 (namely, the gear rotates to a part without the teeth), the elastic force accumulation contact of the second spring can rebound to drive the rack 68 to slide reversely, the rack 68 can drive the second gear 67 to rotate reversely, the material throwing belt 60 drives the impact block 63 to impact towards the molybdenum ore particles, the molybdenum ore can be impacted to horizontally fly out from the material throwing channel 62 to perform a flat throwing motion, so that the flat throwing track length of the molybdenum ore particles is increased, and the sorting effect of the molybdenum ore particles is improved.
