After the pneumatic vibrator drives the crushing claw 124 to crush the outer cylindrical coating of the sampling bomb, the sliding block 131b of the sliding assembly 131 drives the sliding rotary cylinder 132, the sliding bracket 133 and the sliding gas claw 134 to be away from the rest of the sampling bomb 100. The sliding rotary cylinder 132 drives the sliding bracket 133, the sliding gas claw 134 and the sample 600 to rotate clockwise by 90 degrees, and the next process is delivered.

The debris collection assembly includes: a chip hopper 14, a chip conveyer belt 15 and a chip collecting box 16.

The end of the conveyor belt 15 is provided with a debris collection bin 16.

The chips dropped off by the sampling bullet 100 automatically fall by gravity into the chip hopper 14 and onto the conveyor belt 15, which transports the chips into the chip collection bin 16.

The working process of the automatic crushing device is as follows:

the rotating cylinder 111 rotates to drive the rotating fixing plate 112 and all the components mounted on the rotating fixing plate 112 to rotate 90 degrees, the center of the rotating shaft is vertical, and the opening of the gripper pneumatic claw 119 faces upward. The gripper gas claw 119 is opened to bring the copying

grippers

119a and 119b open, and the shot 100 which has been taken out of the molten steel passes through the center hole 113b of the rotating shaft 113 in a vertical state and is placed in the

gripping jaws

119a and 119b, and then the gripper gas claw 119 brings the two

copying gripping jaws

119a and 119b closed to grip the shot 100. Then the rotating cylinder 111 drives the rotating fixing plate 112 to rotate 90 degrees in the opposite direction, so that the sampling bomb 100 is in a horizontal state.

The sliding assembly 131 moves towards the sampling bomb 100, and drives the sliding air claw 134 to move in the same direction. At this point, the three sliding jaws 135 are opened, the handle of the sample 600 enters the sliding jaws 135, and the three sliding jaws 135 close to grip the handle of the sample 600.

The guide rod cylinder 121 is slowly pushed forward to drive the pneumatic vibrator 123 and the crushing claw 124 to be close to the sampling bomb 100 until the crushing tooth 124 contacts the excircle of the sampling bomb 100 and exerts certain pressure on the excircle of the sampling bomb, and the pneumatic vibrator 123 vibrates at high frequency, so that the crushing claw 124 is driven to break the excircle coating of the sampling bomb. After the crushing claw 124 reaches the preset position, the guide rod cylinder 121 drives the pneumatic vibrator 123 and the crushing claw 124 to retract, and drives the vibrator 123 and the crushing claw 124 to reset and to be far away from the sampling bomb 100. Meanwhile, the servo motor 114 is started, and the output shaft thereof rotates, so as to drive the driving gear 116 and the driven gear 116a to rotate, i.e. to drive the rotating shaft 113 to rotate, i.e. to drive the whole gripper assembly mounted on the rotating shaft 113 to rotate by a preset angle, i.e. to rotate the sampling bomb 100 by a preset angle. The guide rod cylinder 121 is slowly pushed forwards again to drive the pneumatic vibrator 123 and the crushing claw 124 to be close to the sampling bomb 100 until the crushing tooth 124 contacts the outer circle of the sampling bomb 100 and exerts certain pressure on the outer circle of the sampling bomb, and the pneumatic vibrator 123 vibrates at high frequency, so that the crushing claw 124 is driven to break the outer circle cladding of the sampling bomb. Repeatedly knocking different parts of the bullet until the outer cladding of the bullet completely falls off. The debris that falls off the sampling bullet 100 during the knocking process automatically falls by gravity into the debris hopper 14 and onto the conveyor belt 15, which transports the debris into the debris collection bin 16.

After the bullet wrapper completely falls off, the sliding block 131b of the sliding assembly 131 drives the sliding rotary cylinder 132, the sliding bracket 133 and the sliding gas claw 134 away from the remaining sampling bullets 100. The sliding rotary cylinder 132 drives the sliding bracket 133, the sliding gas claw 134 and the sample 600 to rotate clockwise by 90 degrees, and the next process is delivered.

The automatic smashing device provided by the invention has high automation degree, can automatically complete knocking on the outer cladding of the sampling bomb by the device, completely replaces manual knocking on the outer cladding by a small hammer, can effectively avoid scalding of the high-temperature outer cladding on a human body and damage of dust on the human body during knocking, can realize an unmanned sample piece taking task by matching with other devices, can effectively improve the production efficiency, improves the qualification rate of the sample piece, and reduces the potential safety hazard during operation of workers.
