Preferably, in order to drive the lifting ring 17 to reciprocate, the lifting unit comprises a connecting rod 25, a push rod 26 and a through hole, the through hole is arranged on the fixed pipe 16, the axis of the push rod 26 is perpendicular to and intersects with the axis of the driving shaft 14, the push rod 26 passes through the through hole, the push rod 26 is connected with the inner wall of the through hole in a sliding and sealing manner, one end of the push rod 26 close to the driving shaft 14 is arranged on the ball 24, the other end of the push rod 26 is hinged with the lifting ring 17 through the connecting rod 25, the connecting rod 25 is arranged in an inclined manner, and a gap is arranged between the push rod 26 and the lifting ring 17.

The rotation of the eccentric wheel 23 drives the push rod 26 to reciprocate through the balls 24, and the reciprocating movement of the push rod 26 drives the lifting ring 17 to reciprocate through the connecting rod 25.

During the use of the device, the sealing cover 2 is opened, at the moment, the moving disc 12 can move towards the direction far away from the transmission shaft 4 through the moving unit, at the moment, the air in the guide pipe 8 can not be discharged from the air pipe 9 through the one-way characteristic of the second one-way valve 11, and only the air in the guide pipe 8 can be conveyed into the cleaning pipe 7, the air in the cleaning pipe 7 can be discharged from the bottom end of the cleaning pipe 7 and acts on the blade 6, then the raw material is put into the shell 1 and then the sealing cover 2 is covered, at the moment, the moving disc 12 can move reversely through the moving unit, and through the one-way characteristic of the first one-way valve 10, the air in the cleaning pipe 7 can not be conveyed into the guide pipe 8, and only the air can be conveyed into the guide pipe 8 from the air pipe 9, then, the first motor 3 is started, the transmission shaft 4 drives the rotating pipe 5 to rotate, and the rotating of the rotating pipe 5 drives the moving blade 6 to rotate, that is, the blade 6 can crush the raw material, after the raw material is crushed, the sealing cover 2 is opened again to discharge the raw material, and when the air discharged from the cleaning tube 7 acts on the blade 6, the raw material remained on the blade 6 can be blown off, thereby realizing the function of automatically cleaning the blade 6, during the crushing of the raw material, the second motor 13 is started, so that the driving shaft 14 can drive the screw 15 to rotate, the driving shaft 14 rotates to drive the lifting ring 17 to reciprocate through the lifting component, when the lifting ring 17 rises and is separated from the feeding hole, the raw material can be conveyed into the fixed tube 16 from the feeding hole, when the lifting ring 17 descends, the raw material clamped on the feeding hole can be extruded and crushed, thereby increasing the crushing mode of the raw material to improve the crushing efficiency, and preventing the feeding hole from being blocked, and in fact, the rotation direction of the screw 15 is opposite to the rotation direction of the rotating tube 5, and the rotation of screw rod 15 then can promote the raw materials and carry to the rotating tube 5 in, the raw materials in the rotating tube 5 is again discharged from the discharge opening and is fallen on blade 6 to can carry the raw materials that deposits in casing 1 bottom to blade 6 on, can improve raw materials crushing efficiency.

Compared with the prior art, this a high-efficient type crushing apparatus for magnesia brick is made has realized cleaning blade 6's function through clean mechanism, compare with current clean mechanism, this clean mechanism is through the clean pipe 7 discharge of the on-off control of sealed lid 2, degree of automation is higher, the practicality is stronger, moreover, still improve raw materials crushing efficiency through complementary unit, compare with current complementary unit, this complementary unit passes through the cooperation between fixed pipe 16 and the rotating tube 5, can also reduce the run-out that produces during transmission shaft 4 rotates, improve transmission shaft 4 pivoted stability, the practicality is stronger.

In light of the foregoing description of the preferred embodiment of the present invention, many modifications and variations will be apparent to those skilled in the art without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
