The working principle by all the matters in the above embodiments is as follows: the initial state is as follows: the fixed disk 502 and the feed inlet 512 on the rotating ring 503 are in a staggered state, at this time, the barite block material cannot pass through the feed inlet 512 on the fixed disk 502 under the blocking of the rotating ring 503, the return spring 514 is in a normal state, and at this time, the lower end of the vibrating rod 513 and the return spring 514 are positioned on the same horizontal line.
The following is the working procedure of the agitation guard mechanism 5 for removing the corners and tips of the heavy rock: when the feeder is used, barite block materials are put into the feeding pipe 31, the driving motor 404 is started, the driving motor 404 rotates to drive the centrifugal disc 412 to rotate, the centrifugal disc 412 rotates to drive the linkage shaft 501 to rotate, when the linkage shaft 501 rotates, the linkage shaft 501 drives the rotating ring 503 to rotate through the connecting rod 504, so that the feeding hole 512 on the rotating ring 503 is gradually close to and aligned with the feeding hole 512 on the fixed disc 502 when rotating, and therefore, the materials in the feeding pipe 31 can be partially discharged through the feeding hole 512, and further, under the condition that the linkage shaft 501 continuously drives the rotating ring 503 to rotate, the feeding hole 512 on the rotating ring 503 is continuously aligned with or staggered with the feeding hole 512 on the fixed disc 502, thereby realizing intermittent feeding of the materials in the feeding pipe 31, preventing the materials from entering the machine body 1 at one time and reducing the load when the machine body 1 is used.
In addition, in the process that the linkage shaft 501 drives the rotating ring 503 to rotate and intermittent discharging is completed, the linkage shaft 501 simultaneously drives the second polishing shaft 508 and the driving gear 505 to rotate, and the driven gear 507 is meshed with the driving gear 505, so that the first polishing shaft 506 is driven to simultaneously rotate under the transmission of the driving gear 505 and the driven gear 507, and further, the connecting column 510 and the stirring blade 511 can be simultaneously driven to rotate through the rotation of the second polishing shaft 508, so that stirring of the stirring blade 511 in the feeding pipe 31 is realized, the barite block material in the feeding pipe 31 can flow through the stirring of the stirring blade 511 and the rotation of the second polishing shaft 508 and the first polishing shaft 506, friction can be generated between the barite block material and the rotating first polishing shaft 506 and the rotating second polishing shaft 508 when the barite block material flows, and friction can be generated between the barite block material and the inner surface of the feeding pipe 31, furthermore, through the arrangement of the second grinding bars 516 and the first grinding bars 509, when the flowing barite block materials are rubbed with the inner surface of the feeding pipe 31, the first grinding shaft 506 and the second grinding shaft 508, the friction force of the barite block materials can be increased, and meanwhile, when the barite block materials flow, friction collision can be generated between the barite block materials, so that the edges and the tips of the surfaces of the barite block materials can be ground off through the friction collision between the barite block materials and the friction between the barite block materials and the first grinding shaft 506 and the second grinding shaft 508, the edges and the tips of the surfaces of the barite block materials are reduced before entering the machine body 1, and when grinding wheels in the machine body 1 grind the barite block materials, the stress between the barite block and the grinding wheels is reduced, and the situation that the grinding wheels are worn too fast due to too concentrated stress is avoided.
Further, when the connecting rod 504 drives the rotating ring 503 to rotate, the cambered surface of the connecting rod 504 gradually approaches the bottom end of the vibrating rod 513, so that under the extrusion of the cambered surface of the connecting rod 504 to the vibrating rod 513, the vibrating rod 513 can be pushed to slide upwards, the reset spring 514 compresses, and the bottom of the vibrating rod 513 is gradually staggered along with the continuous rotation of the connecting rod 504, and then under the driving of the rebound force of the reset spring 514, the vibrating rod 513 can slide downwards again and reset, and then under the cooperation of the reset spring 514, the vibrating rod 513 can be continuously driven to reciprocate up and down, so as to drive the stirring rod 515 to vibrate up and down, and then through the up and down vibration of the stirring rod 515, the stirring effect of the barite block material in the feeding pipe 31 can be improved, the stirring blade 511 can finish the stirring of the upper and lower directions of the barite block material through the up and down vibration of the stirring rod 515, and further the collision friction effect of the barite block material is improved, and meanwhile, the phenomenon of stirring the vertical vibration of the rod 515 and the stirring blade in the horizontal direction of the stirring blade 511 can be improved, and the material passing through the feeding hole 512 in the feeding pipe 31 can be prevented from passing through the feeding hole when the material is stable.
The above operation is described with reference to fig. 3 to 10.
The following is the working procedure of the filtering and protecting mechanism 4 for filtering and crushing the heavy stone blocks: furthermore, when the barite block material is intermittently fed from the feed inlet 512 on the stirring and protecting mechanism 5, the material falls onto the upper surface of the centrifugal disc 412 under the guide of the guide ring 517, and the driving motor 404 drives the centrifugal disc 412 to continuously rotate through the reciprocating screw rod 405, so that the size of the centrifugal force is proportional to the mass of the object, the barite block material falling onto the centrifugal disc 412 in normal size can pass through the discharge hole 413 and enter the machine body 1 through the feed pipe 2 for grinding, and the larger material can slide out from the conical surface of the centrifugal disc 412 and then pass through between the feed hopper 3 and the feed pipe 31 due to the larger centrifugal force, falls into the collecting ring 408 under the guide of the inclined surface of the connecting cover 407 and the conical ring 409 and is positioned on the convex block 410, and the larger barite block material can be removed under the cooperation of the arrangement of the discharge hole 413 and the centrifugal force, so that the problem that the material flow is not smooth and the abrasion of parts in the machine body 1 is prevented from being accelerated is avoided when the larger barite block material enters the machine body 1.
In addition, when driving motor 404 is driving reciprocating screw rod 405 and rotating, can make slip loop bar 406 drive clamping ring 407 reciprocates, when clamping ring 407 moves down, lug 410 on clamping ring 407 is close to the material direction that falls into collecting ring 408, and then through the extrusion of lug 410 on clamping ring 407 and collecting ring 408, can smash great heavy crystal stone piece material, the staff can install annular collecting box at feeder hopper 3 surface, the barite piece material after smashing can pass collecting hole 411 and fall into collecting box and collect, the barite piece material after collecting has become normal size this moment, can pour into again and throw material pipe 31 and go into in organism 1 and carry out the crocus processing.
The above operation is described with reference to fig. 1 to 6.
