[0015] Preferably, the hard lump removal assembly includes a through groove opened along the inside of the inclined groove, and the through groove passes through the middle rotating cylinder and is connected to the outside.

[0016] An inner groove corresponding to the end of the rotating shaft is provided inside the middle rotating cylinder, and the inner groove is communicated with the annular cavity. A rack is slidably connected in the inner groove, and the rack is fixedly connected to the slip ring.

[0020] Preferably, both ends of the steel cable are respectively mounted on the slip ring and the turntable by bolts.

[0021] Preferably, a transparent observation window corresponding to the steel cable is fixedly embedded on the rotating drum.

[0022] A method for using a corundum abrasive feeding device comprises the following steps: S1. The material in the silo falls into the chute along the entrance, then enters the dispersion chamber, and uses the roller to disperse the compacted material blocks in the material. Finally, it falls into the conveying auger along the exit and is transported to the processing equipment; S2. The material entering the dispersion chamber from the chute reaches the cage structure formed by the turntable, the connecting rod and the ring seat. The motor drives the turntable to rotate, so that the cage structure rotates synchronously. Normal materials fall into the outlet along the gap of the connecting rod, while the hardened material blocks are stuck by the connecting rod. In this process, the rotating cage brings the material blocks to the upper position and then falls to be crushed. The extrusion rod uses gravity to reciprocate along the chute during the rotation process, so that the extrusion rod is used to crush the material blocks along the connecting rod; S3. When the turntable rotates, one end of the steel cable is driven to perform circular motion, so that the steel cable is pulled out of the ring cavity for twisting, and the material in the cage structure is shredded by the steel cable. During this process, the steel cable is twisted progressively from the outlet end to the inlet end, and the un-shredded hard blocks are pushed toward the inlet direction; S4. When the steel cable is not twisted, the baffle falls down to close the through slot. At this time, the material falling into the entrance enters the dispersion chamber along the inclined slot. When the steel cable is twisted and pulled out of the ring cavity, it synchronously drives the slip ring compression spring to move, so that the rack drives the rotating shaft along the ring gear and the baffle flips upward. At this time, the inclined slot connects the dispersion chamber with the through slot, and the hard block pushed by the twisted steel cable is squeezed into the through slot along the inclined slot and discharged.

[0023] Compared with the prior art, the present invention has the following beneficial effects: In the present invention, the material blocks are brought to the upper position by a rotating cage and then dropped to be crushed, and the extrusion rod utilizes gravity to slide back and forth along the slide groove during the rotation process, so that the material blocks are crushed along the connecting rod by the extrusion rod. Compared with the existing multi-stage material processing using structures such as stirring rods and centrifugal disks, the cage structure of the connecting rod can drive the material blocks to fall, collide and disperse, and there is no need for high-speed rotating centrifugal components to scatter the material blocks, thereby reducing the strong vibration and noise generated by the operation of the equipment and the collision of the material blocks, and the low-speed equipment has better operation safety. At the same time, the movement of the extrusion rod is achieved by position change and gravity, rather than active drive, which can avoid the dispersion components from getting stuck when the material blocks are not broken.

[0024] In the present invention, a steel cable is pulled out of the annular cavity by a turntable to be twisted, and the steel cable is used to shred the material in the cage structure. During this process, the steel cable is progressively twisted from one end of the outlet to the other end of the inlet, and the unshredded hard blocks are pushed toward the inlet. Compared with the existing single drop discharge structure, the steel cable can not only shred the material blocks, but also push the hard blocks that cannot be processed this time away from the outlet area. On the one hand, it can avoid the accumulation of hard blocks in the outlet area to cause blockage. On the other hand, the lateral movement of the hard blocks can be used to rub against other components and hard blocks to assist in the fragmentation and dispersion of the hard blocks.

[0025] In the present invention, the steel cable is twisted and pulled out of the ring cavity, which synchronously drives the slip ring compression spring to move, so that the rack drives the rotating shaft and the baffle to flip upward along the ring gear. At this time, the inclined groove connects the dispersion cavity with the through groove, and the hard blocks pushed by the twisted steel cable are squeezed into the through groove along the inclined groove and discharged. Compared with the existing single-channel dispersion and conveying structure, the baffle can intermittently open the independent channel formed by the through groove, so that the hard blocks that cannot be handled in the cage structure are removed and discharged from the dispersion operation by the twisted steel cable, which can effectively prevent the hard blocks that cannot be handled from clogging the equipment.

A method for using a corundum abrasive feeding device, using the corundum abrasive feeding device as claimed in claim 3, characterized in that: The steps include: S1, the material in the silo falls into the chute (57) along the inlet (4), then enters the dispersion chamber (51), and the compacted material blocks in the material are dispersed by the roller (5), and finally falls into the conveying auger (1) along the outlet (3) and is transported to the processing equipment; S2, the material entering the dispersion chamber (51) from the chute (57) reaches the cage structure formed by the rotating disk (55), the connecting rod (56) and the ring seat (53), and the rotating disk (55) is driven by the motor (58) to rotate, so that the cage structure rotates synchronously, and normal materials fall into the outlet (3) along the gap of the connecting rod (56), while the hardened material blocks are caught by the connecting rod (56). During this process, the rotating cage brings the material blocks to the upper position and then falls to be crushed, and the squeezing rod (59) uses gravity to reciprocate along the chute (510) during the rotation process, so that the squeezing rod (59) is used to crush the material blocks along the connecting rod (56); S3, when the turntable (55) rotates, one end of the steel cable (5121) is driven to perform a circular motion, so that the steel cable (5121) is pulled out of the annular cavity (5122) and twisted, and the steel cable (5121) is used to grind the material in the cage structure. During this process, the steel cable (5121) is progressively twisted from one end of the outlet (3) to one end of the inlet (4), and the hard blocks that are not ground are pushed toward the inlet (4); S4, when the steel cable (5121) is not twisted, the baffle (51253) falls down to close the through groove (51251), and the material falling into the inlet (4) enters the dispersion chamber (51) along the inclined groove (57). When the steel cable (5121) is twisted and pulled out of the ring cavity (5122), the sliding ring (5123) is synchronously driven to compress the spring (5124) to move, so that the rack (51255) drives the rotating shaft (51252) and the baffle (51253) to turn upward along the ring gear (51256). At this time, the inclined groove (57) connects the dispersion chamber (51) with the through groove (51251), and the hard block pushed by the twisted steel cable (5121) is squeezed into the through groove (51251) along the inclined groove (57) and discharged.
