Referring to fig. 5 and 8, in order to ensure transmission between the double pressing block 7 and the filtering frame and extrude ore blocked in the filtering frame, at least two ring rods 11 are coaxially installed between the ring rods 11, the ring rods 11 are fixed by cross rods 10, central axes between the cross rods 10 and the ring rods 11 are parallel to each other, and a plurality of cross rods 10 are equiangularly distributed, the cross-sectional shape of the double pressing block 7 is circular, arc grooves adapted to the cross rods 10 are formed on the double pressing block 7, and angles between the arc grooves are adapted to angles between the cross rods 10, so that when the double pressing block 7 rotates, the cross rods 10 are pushed to rotate by the rotation of the double pressing block 7 through the arc grooves, the ring rods 11 are driven to rotate, and when the double pressing block 7 passes through the transmission process, the ore clamped between the cross rods 10 and the ring rods 11 is extruded, thereby guarantee not only the filtration of assurance ore of filter frame, still self prevents stifled, and can throw up the ore and realize the breakage once more.

Referring to fig. 4 and 5, in order to further enhance the crushing strength of the ore in the filtering frame, the crushing cones 9 are disposed on the outer side of the re-pressing block 7 and the inner side of the filtering frame, and the outer side wall of the re-pressing block 7 is close to the side wall of the crushing frame 6 when being driven by the cross bar 10, so that the ore falling into the filtering frame is ensured to be sheared along with the relative rotation between the re-pressing block 7 and the crushing frame 6 during crushing, and the crushing strength of the ore is further greatly enhanced by the extrusion between the re-pressing block 7 and the crushing frame 6.

Please refer to fig. 2, wherein, for further increasing the crushing strength of the ore, the diameter value of the crushing belt wheel 4 is two times of the diameter value of the anti-blocking belt wheel 5, so that the anti-blocking belt wheel 5 is driven by the rotation of the crushing belt wheel 4 to accelerate when crushing, and further the crushing cone head 9 in the filtering frame is forced to crush the ore synchronously, on the other hand, the ore throwing speed is increased by increasing the rotation speed of the filtering frame, and the thrown ore impacts the crushing cone head 9 on the crushing frame 6 at an accelerated speed due to the relative rotation between the crushing frame 6 and the filtering frame, thereby greatly enhancing the crushing strength.

Referring to fig. 4, 6 and 7, in order to promote different crushing modes of ore in the filtering frame under different load conditions, therefore, the outer side wall of the crushing frame 6 is fixedly provided with the movable sheet 12, the movable sheet 12 is a metal sheet, the surface of the movable sheet 12 is fixedly provided with the crushing conical head 9, and simultaneously, the crushing frame 6 is filled with liquid medium, so that when the crushing frame 6 rotates at low speed, the movable sheet 12 is simultaneously extruded outwards through the extrusion and crushing between the composite pressing block 7 and the crushing conical head 9, so that the comprehensive crushing is realized, at high speed of rotation, the movable blades 12 are pushed outwards by the medium in the crushing frame 6 under the influence of centrifugal force, thereby rapidly crushing the residual ore in the filtering frame, and the liquid medium in the application can adopt an oil medium.

Referring to fig. 6 and 7, in order to ensure that the crushing cone head 9 on the movable plate 12 cannot be crushed due to insufficient strength of the movable plate 12 during the crushing process, so that by fixedly installing the stopper 13 positioned inside the movable piece 12 on the inner wall of the crushing frame 6, one end of the crushing conical head 9 on the movable sheet 12 passes through the stop block 13 and is positioned in the inner cavity of the crushing frame 6, and the stop block 13 is movably connected with the crushing conical head 9, so that in the working process, when the crushing conical head 9 is used for crushing, the rotating force of the crushing frame 6 can be transmitted through the stop block 13, and due to the arrangement of the stop block 13, when the ore is relatively extruded between the composite pressing block 7 and the crushing frame 6, the stopper 13 limits the inward movement of the movable plate 12, so that the phenomenon that the movable plate 12 is damaged due to overlarge pressing force of the movable plate 12 is avoided.

The working principle of the invention is as follows: when the crushing device is used, referring to the attached drawing 4, the crushing frame 6 is driven by the power mechanism 2 to rotate anticlockwise, the crushing belt wheels 4 rotate synchronously, the crushing belt wheels 4 rotate the composite block 7 synchronously through the anti-blocking belt wheels 5, and at the moment, the composite block 7 rotates anticlockwise.

Then, the ores are placed in the filtering frame from the feeding hopper 3, the crushing conical head 9 on the crushing frame 6 can crush the ores, the crushed ores are filtered by the filtering frame and then are discharged from the discharge opening 8, and the ore that cannot be discharged from the filtering frame is rotated by the ring rod 11 of the double pressing block 7 through the cross rod 10, the crushing cone head 9 on the ring rod 11 not only crushes the ore, but also throws up the ore through the rotation of the ring rod 11, since the ring rod 11 rotates clockwise and the crushing frame 6 rotates anticlockwise, the thrown ore can quickly impact on the crushing conical head 9 on the crushing frame 6, thereby reinforcing broken intensity, another face has realized preventing stifled band pulley 5's acceleration through smashing band pulley 4, therefore makes the intensity increase of shedding of ore, and then strengthens the impact strength of ore.

And make the pivoted in-process of loop bar 11 through horizontal pole 10 at double briquetting 7, through the inboard of going into loop bar 11 of the continuous top of double briquetting 7 to can make the card to push into the inboard of loop bar 11 to the ore between horizontal pole 10 and loop bar 11, and then carry out the breakage once more.

When ore in the hopper 3 enters the inner side of the ring rod 11, the ore is input to the position of the re-pressing block 7 by the rotation of the crushing frame 6, and because the ore is pressed on the crushing frame 6 at the moment, the load of the power mechanism 2 is increased, the rotation speed is relatively reduced, and along with the output of the ore between the re-pressing block 7 and the crushing frame 6, the ore is sheared by the crushing conical heads 9 on the crushing frame 6 and the re-pressing block 7, so that the ore is crushed, meanwhile, the ore is arranged between the re-pressing block 7 and the crushing frame 6, so that the movable sheet 12 at the side of the re-pressing block 7 is extruded, the crushing conical head 9 on the movable sheet 12 slides in the stop block 13 and pushes towards the inner side of the crushing frame 6, and due to the inward extrusion of the movable sheet 12, the pressure of a liquid medium in the inner cavity of the crushing frame 6 is increased, so that the movable sheets 12 at other parts are pushed outwards, and the movable sheet 12 pushed outwards pushes the crushing conical head 9 to press the crushing conical head 9 on the cross rod 10 and the ring rod 11, therefore, the ore is crushed by extrusion, and meanwhile, the extruded ore is subjected to shearing force between the ring rod 11 and the crushing frame 6 by relative rotation between the ring rod and the crushing frame, so that the ore is further crushed; and after the ore on the crushing frame 6 reduces, and when still leaving the ore in filtering frame, at this moment, the load in the crushing frame 6 reduces relatively, and rate of rotation strengthens relatively, therefore make the rotation of the further increase of briquetting 7 to filtering frame, make the intensity of shedding of ore increase, meanwhile, receive the increase of crushing frame 6 rotation intensity, can make the liquid medium of crushing frame 6 inner chamber receive centrifugal force to outwards extrude, and along with high-speed pivoted crushing cone head 9, further reinforcing is broken the ore in filtering frame, until the ore in filtering frame is all discharged from bin outlet 8.
