Referring to fig. 7, a truncated cone-shaped blanking opening 521 is uniformly formed in the left half of the bottom of the grinding pan 52, and an elastic steel ball 523 is connected to the inner side wall of the truncated cone-shaped blanking opening 521 through a light spring 522. During specific work, in the rolling process of the grinding balls 53, the grinding balls 53 can extrude the elastic material steel balls 523 to drive the elastic material steel balls 523 to move downwards, at the moment, the circular truncated cone-shaped blanking port 521 is in an open state, the ground water-based expansion type fireproof coating raw materials can fall downwards into the fine material collecting frame 58 through the circular truncated cone-shaped blanking port 521 to be collected and processed in a centralized mode, when the grinding balls 53 roll over the circular truncated cone-shaped blanking port 521, the light springs 522 drive the elastic material steel balls 523 to reset, the water-based expansion type fireproof coating raw materials above the elastic material steel balls 523 are ejected upwards, and therefore the circular truncated cone-shaped blanking port 521 can be prevented from being blocked.

Referring to fig. 6, the vibration mechanism 54 includes a reciprocating electric push rod 541, a sliding block 542, a buffer spring 543 and a connecting rod 544, wherein a rectangular sliding groove is formed in a position, close to the right end, of the upper end surface of the bottom plate 1, the sliding block 542 is slidably mounted in the rectangular sliding groove, the sliding block 542 is fixedly connected to an extending end of the reciprocating electric push rod 541, the reciprocating electric push rod 541 is mounted on the bottom plate 1 through a push rod base, the buffer spring 543 is mounted between the sliding block 542 and the left side wall of the rectangular sliding groove, the connecting rod 544 is rotatably connected to the middle of the upper end surface of the sliding block 542 through a pin, and the upper end of the connecting rod 544 is rotatably connected to the grinding pan 52 through a pin. During specific work, the reciprocating electric push rod 541 drives the sliding block 542 to reciprocate left and right, so as to drive the connecting rod 544 to rotate in a reciprocating manner, and the grinding dish 52 is driven to swing up and down in a reciprocating manner by the extrusion or stretching of the connecting rod 544 on the grinding dish 52, so as to complete the secondary grinding and crushing process.
