[0020] Furthermore, the lifting assembly includes a mounting seat 2, a support rod 201 and a protective frame 3; the mounting seat 2 is provided with four groups, and the four groups of mounting seats 2 are distributed on the side walls around the breaker body 1; the support rod 201 is provided with four groups, one end of the support rod 201 is detachably connected to the mounting seat 2 by bolts, and the other end of the support rod 201 is connected to a connecting seat 202, and the connecting seat 202 is provided with four groups; the side walls around the protective frame 3 are all provided with fixing frames 302, and screws are provided on two groups of opposite fixing frames 302 303, the screw rod 303 is driven to rotate by a motor arranged at the top of the fixing frame 302, and the other two sets of opposite fixing frames 302 are each provided with a fixing rod 304, the screw rod 303 and the fixing rod 304 are respectively connected to the corresponding connecting seat 202, and the connecting seat 202 is slidably connected to the fixing rod 304 or threadedly connected to the screw rod 303; the side walls around the protective frame 3 are each provided with a reinforcing rod 301, and the reinforcing rod 301 is vertically arranged with the corresponding fixing frame 302 to improve the overall stability of the protective frame 3.

[0021] In this embodiment, the top of the breaker body 1 is connected to an excavator, a loader or a pump station to obtain power. After the drill rod is aligned with the stone to be broken, the screw 303 is driven to rotate by the motor. Since the screw 303 is threadedly connected to the connecting seat 202, the screw 303 moves downward along the connecting seat 202 and is adjusted to a suitable height. Then, the protective frame 3 is driven to move downward through the fixing frame 302 to surround the drill rod. At this time, multiple groups of elastic shielding cloths 4 on the side walls of the protective frame 3 surround the drill rod. When the broken stones generated by the drill rod are splashed, the broken stones hit the elastic shielding cloth 4 and are intercepted, so as to prevent the broken stones from continuing to move and causing damage to the surrounding equipment or personnel, thereby reducing the danger. As the drill rod continues to penetrate into the stone, the protective frame 3 is adjusted downward along with the drill rod under the action of the motor and the screw 303, so as to intercept the broken stones and improve safety.
