The horizontal shaft 11 and the connecting shaft 12 are connected by a belt 13, and the two ends of the horizontal shaft 11 are fixedly provided with connecting gears 14, and the bottom of the connecting bracket 8 is provided with two sets of vertical tooth plates 15, and the vertical tooth plates 15 are engaged with the connecting gears 14; when working, the connecting bracket 8 follows the reciprocating cylinder 6 moves, the connecting bracket 8 will drive the two sets of vertical tooth plates 15 at the bottom thereof to move upward, and the vertical tooth plates 15 will drive the connecting gears 14 meshing therewith to rotate when moving upward, and the connecting gears 14 will drive the horizontal shaft 11 to rotate, and the horizontal shaft 11 will drive the connecting shaft 12 to rotate through the belt 13, and the connecting shaft 12 will drive the center gear 10 to rotate, and the center gear 10 will drive the horizontal tooth plates 301 meshing therewith to move, that is, the horizontal tooth plates 301 will drive the sand mill barrel 2 to move as described above, and the operation is more convenient.

[0038] Both side walls of the vertical tooth plate 15 are provided with vertical grooves 151, and a limiting bracket 16 is installed inside the fixed frame 9, and the limiting bracket 16 is arranged inside the vertical groove 151 on the side away from the fixed frame 9; during operation, when the vertical tooth plate 15 moves upward, under the mutual limitation of the limiting bracket 16 and the vertical groove 151, the vertical tooth plate 15 will move in a vertical line, which can facilitate the vertical tooth plate 15 to drive the connecting gear 14 to rotate, and the connecting gear 14 drives the horizontal shaft 11 to rotate. Such a design can not only automatically pull out the grinding part 4, but also automatically pull the sand mill barrel 2 out of the accommodating groove 101, which has high linkage and high intelligence.

[0039] The side wall of the slide 3 is provided with a telescopic limit arc block 17, and the outer circumferential surface of the telescopic limit arc block 17 is provided with a telescopic spring 171, one end of the telescopic spring 171 is connected to the side wall of the slide 3, and the other end is connected to the outer circumferential surface of the telescopic limit arc block 17, and the inner wall of the limiting groove 7 is provided with a fixing groove 18, and the fixing groove 18 is adapted to the shape of the telescopic limit arc block 17; during operation, in the initial state, that is, when the sand mill cylinder 2 is located inside the accommodating groove 101, the telescopic limit arc block 17 of the side wall of the slide 3 is located inside the fixing groove 18, so that the slide 3 can be easily stuck in the fixing groove 18, and when the grinding part 4 is normally used inside the sand mill cylinder 2, the clamping of the slide 3 can avoid the problem of position displacement of the slide 3 when the sand mill cylinder 2 is subjected to vibration;

[0040] Moreover, since the outer surface of the telescopic limit arc block 17 is provided with a telescopic spring 171, and the telescopic limit arc block 17 is designed to be telescopic, when the transverse tooth plate 301 pulls the slide 3 to move, the slide 3 can easily drive the telescopic limit arc block 17 to disengage from the inside of the fixed groove 18, thereby facilitating the sand mill barrel 2 to disengage from the inside of the accommodating groove 101.

[0041] The outer peripheral surface of the telescopic limit arc block 17 is installed with contact 19, and the groove wall of the fixed groove 18 is provided with contact 2 20; during operation, after the sand mill barrel 2 is overhauled once, the telescopic end of the reciprocating cylinder 6 is moved downward, and the connecting bracket 8 drives the vertical tooth plate 15 to move downward, that is, the above-mentioned mechanism moves in the opposite direction, and the slide 3 drives the sand mill barrel 2 to move toward the inside of the accommodating groove 101. When the slide 3 drives the telescopic limit arc block 17 and the contact 1 19 on its surface to move to the inside of the fixed groove 18, the contact 1 19 will contact with the contact 2 20, and the contact 2 20 will transmit the contact signal to the controller through its external power line. The controller will control the reciprocating cylinder 6 to stop moving, that is, at this time the grinding part 4 just moves to the inside of the sand mill barrel 2, which is convenient for the normal use of the subsequent sand mill.

[0043] When the grinding part 4 needs to be taken out, the lifting mechanism is controlled to drive the grinding part 4 to move upward, so that the grinding part 4 is away from the sand mill cylinder 2, and then the sand mill cylinder 2 is driven to move at the bottom of the receiving tank 101 by the slide 3, so that the sand mill cylinder 2 is away from the receiving tank 101. Such a design can automatically take out the sand mill cylinder 2 and the grinding part 4, thereby facilitating the replacement or maintenance of the cylinder and the grinding part 4, and no manual operation is required, which is more convenient and quick. When the grinding part 4 needs to be taken out, the telescopic end of the reciprocating cylinder 6 is controlled to move so that the telescopic end drives the grinding part 4 to move upward, and then the grinding part 4 will move up from the inside of the sand mill cylinder 2, and gradually move up from the inside of the supporting frame 1 and the protective frame 5, that is, the function of automatically taking out the grinding part 4 is realized, which is more convenient to operate.

When the vertical tooth plate 15 moves upward, under the mutual limitation of the limit bracket 16 and the vertical groove 151, the vertical tooth plate 15 will move in a vertical line, which can facilitate the vertical tooth plate 15 to drive the connecting gear 14 to rotate, and the connecting gear 14 drives the horizontal shaft 11 to rotate. Such a design can not only automatically pull out the grinding part 4, but also automatically pull the sand mill barrel 2 out of the receiving groove 101, which has high linkage and high degree of intelligence.

[0046] In the initial state, that is, when the sand mill barrel 2 is located inside the receiving groove 101, the telescopic limit arc block 17 of the side wall of the slide 3 is located inside the fixed groove 18.
