When in use, materials are put on the first sieve hopper 5 from the feed inlet 2, impurities are sieved into the bottom discharge cabin by the left and right vibration generated by the first sieve hopper 5, meanwhile, the vibration effect generated by the first sieve hopper 5 is transmitted to the second sieve hopper 6 through the hinge 7, meanwhile, under the left and right vibration effect, the materials in the first sieve hopper 5 flow into the second sieve hopper 6, then the impurities are sieved into the bottom discharge cabin after being sieved through the second sieve hopper 6, because the first sieve hopper 5 and the second sieve hopper 6 which form the sieving component 4 are chain type vibrating sieves hinged together through the hinge 7, the first sieve hopper 5 and the second sieve hopper 6 can not deflect downwards at the hinge 7 at the same time, namely, the left end of the first sieve hopper 5 deflects downwards, the right end of the second sieve hopper 6 deflects downwards, the materials passing through the bottom surfaces of the inner cavities of the first sieve bucket 5 and the second sieve bucket 6 are greatly rolled due to downward deflection between the two materials by utilizing the deflection action generated by the connecting ends of the first sieve bucket 5 and the second sieve bucket 6, the oxide layer on the surface of the materials falls off downwards by utilizing the friction action of friction particles on the surface in the rolling process, then the materials continue to discharge leftwards along with the vibration action, impurities (such as oxide scales) on the surface of the materials can be screened downwards after falling off (falling off) in a shorter stroke when rolling, the first sieve bucket 5 and the second sieve bucket 6 are linked together and gradually incline downwards towards the discharge port 3, so that the front materials can be pushed onto the material warping plate 8 along the second sieve bucket 6 after the above screening is carried out on the rear materials, and finally discharged outwards through the discharge pipe 13 on the discharge port 3 under the guide action of the material warping plate 8.
In the above embodiment, when the first sieve bucket 5 vibrates leftwards, not only the hinged connection and the self gravity are utilized to downwards deflect the hinged end of the first sieve bucket 5 and the hinged end of the second sieve bucket 6, so that the aim of improving the impurity screening efficiency is achieved, but also the effect can be effectively achieved, therefore, when the first sieve bucket 5 vibrates leftwards, the left end of the trigger rod 9 is downwards displaced from the top along the inclined plane 11 of the baffle seat 10, so that the trigger rod 9 drags the left end of the first sieve bucket 5 to downwards deflect, and the right end of the second sieve bucket 6 is downwards deflected by the hinge 7, therefore, the mechanical linkage action is achieved, the device can ensure that the mutually hinged ends of the first sieve bucket 5 and the second sieve bucket 6 hinged together deflect effectively when sieving work is carried out, and ensure that the oxide layer on the material drops downwards by friction particles when the hinged ends of the first sieve bucket 5 and the second sieve bucket 6 deflect downwards (fig. 8 is a schematic diagram when the hinged ends of the first sieve bucket 5 and the second sieve bucket 6 deflect synchronously, but does not have the amplitude when the two sieve buckets deflect, and the amplitude of the deflection is determined by the amplitude of the vibrating force provided by a vibrating source and the elastic strength of the first vibrating spring 51 and the second vibrating spring 61 to the first sieve bucket 5 and the second sieve bucket 6 respectively).
The fence on the first sieve bucket 5 is a first metal material plate 15, the fence on the second sieve bucket 6 is a second metal material plate 16, the two fencing structures enable the first sieve bucket 5 and the second sieve bucket 6 to form a cavity structure, materials can be prevented from falling outwards from the side direction during vibration, one end of the second metal material plate 16 is connected with two second vibration springs 61, a discharge opening 12 is formed in the end of the second metal material plate 16, a flexible rubber plate 17 is connected between the end of the second metal material plate 16 and the inner wall surface of the first metal material plate 15, the bottom surface of the flexible rubber plate 17 is connected to the bottom surface of an inner cavity of the first sieve bucket 5, and the arrangement of the flexible rubber plate 17 can ensure that the first sieve bucket 5 and the second sieve bucket 6 can synchronously deflect at the mutually hinged ends while vibrating and feeding.
The bottom of the screen cabin 1 is provided with a slag discharging port 18, the slag discharging port 18 is positioned below the first screen bucket 5 and the second screen bucket 6 which are hinged through the hinge 7, and the screened and removed impurities (comprising the oxide layer) are screened into the slag discharging port 18, so that the impurities are finally discharged.
The length of the second sieve bucket 6 is three times the length of the first sieve bucket 5, so that the first sieve bucket 5 has a sufficient length distance, impurities which are easy to fall off on the surface fall into the slag discharge port 18 after being sieved before the materials are conveyed to the second sieve bucket 6 along the first sieve bucket 5 in a vibrating manner, then the materials pass through a downward deflection action generated at the hinging position of the first sieve bucket 5 and the second sieve bucket 6, oxide layers possibly existing on the surfaces of the materials or impurities which are difficult to fall off are rolled and rubbed downwards, and finally the materials are discharged rapidly after being sieved by the second sieve bucket 6 with a relatively longer length in a continuous vibrating manner.
As shown in fig. 7, the top surfaces of the opposite ends of the two baffle bases 10 are provided with downward inclined discharge surfaces 19, and the arrangement of the discharge surfaces 19 can ensure that when the screened impurities fall on the baffle bases 10, the impurities are discharged downwards through the discharge surfaces 19, so that the phenomenon that the impurities are accumulated on the top of the baffle bases 10 in a large amount to cause barrier effect on the deflection action of the second screening hopper 6 is avoided.

Therefore, when the first sieve bucket 5 vibrates leftwards, the left end of the first sieve bucket 5 and the right end of the second sieve bucket 6 are ensured to deflect downwards by the aid of the trigger rod 9, the ball end of the trigger rod 9 is pressed against the ejector rod 21 to push downwards, the connecting rod 22 is finally rotated upwards around the rotating rod 23 by means of the hinging relation in the pushing process, so that the tilting part 24 at the tail end of the connecting rod 22 is forced to flap the bottom surface of the tilting plate 8, when the bottom surface of the tilting plate 8 is flapped, the right end of the tilting plate 8 is enabled to rotate upwards, and materials rolling on the rubber sheet 28 during vibration discharging of the second sieve bucket 6 are finally discharged outwards from the discharging hole 3 after being picked up by the aid of the upward rotation. The material tilting plate 8 plays a role in shoveling the materials on the second sieve bucket 6, so that the problem that the materials are difficult to discharge due to the deflection of the lower right amplitude of the second sieve bucket 6 is avoided.
