In this embodiment, when the strength of the rock changes, the control system is used to control the two movable clamping blocks 128 to retract, and then the control system continues to control the impact block 125 to move inwards, so that the first push rod 121 slides in the chute, and slides from the inner end to the outer end of the impact block 125, so as to drive the fourth crushing blade 131 to move to the same circumferential direction of the third crushing blade 129, the second crushing blade 124 to move to the same circumferential direction of the first crushing blade 123, the fourth cutting blade 113 to move to the same circumferential direction of the third crushing blade 129, and the second cutting blade 118 to move to the same circumferential direction of the first cutting blade 117.
By combining the above embodiments, the specific working principle and working process are as follows:
when in use, an operator can switch different modes by detecting the different intensities of rock layers in advance, if the intensity of the rock is high, the control system keeps the initial state as shown in fig. 1, at the moment, the control system controls the locking device to lock the movable clamping block 128, so that the first push rod 121 is temporarily locked at the inner end of the impact block 125 through the locking device, then the control system controls the crushing device 100 to rotate, and the rotation of the outer ring 220 arranged at the outer edge of the shell 210 can limit a ring groove between the face and surrounding rock, so that the face and the surrounding rock are separated; the center of the face is crushed pertinently by the center cutter disc 130 installed at the center of the housing 210, when in driving, the control system drives the first cutter 117, the second cutter 118, the third cutter 112 and the fourth cutter 113 to rotate, the first cutter 117, the second cutter 118, the third cutter 112 and the fourth cutter 113 are sequentially arranged from inside to outside in the radial direction of the face, the first cutter 117, the second cutter 118, the third cutter 112 and the fourth cutter 113 rotate in the circumferential direction thereof, the face is layered, a crushing layer is formed between the first cutter 117 and the second cutter 118, the second cutter 118 and the third cutter 112, the third cutter 112 and the fourth cutter 113 and the circumscribed ring 220, then the control system controls the first cutter 123, the second cutter 124, the third cutter 129 and the fourth cutter 131 electrically connected with the control system to push the crushing layer to the outside, the crushing layer defined by the first cutter 117, the second cutter 124, the third cutter 129 and the fourth cutter 131 is crushed, and the crushing layer is retracted after the crushing is completed. And circulating the operation until the strong rock layer is crushed.
If the detected rock strength is smaller, the operator firstly uses the control system to control the locking device to retract the movable clamping block 128, then the control system controls the impact block 125 to move towards the central cutting disc 130, at this time, the two first push rods 121 can slide in the corresponding sliding grooves, then the fourth crushing cutter 131 can drive the second crushing cutter 124 to move, and when the fourth crushing cutter 131 moves, the control system synchronously controls the fourth cutter 113 to move and drives the second cutter 118 to move. Transition from the state shown in fig. 1 to the state shown in fig. 7. The number of the crushing layers is reduced, and then the control system controls the first crushing blade 123, the second crushing blade 124, the third crushing blade 129 and the fourth crushing blade 131 electrically connected with the first crushing blade, the second crushing blade 124, the third crushing blade 129 and the fourth crushing blade 131 to push outwards, so as to crush the defined crushing layers, and after the crushing is completed, the first crushing blade 123, the second crushing blade 124, the third crushing blade 129 and the fourth crushing blade 131 are retracted. And circulating the operation until the rock layer with small strength is crushed.
The foregoing description of the preferred embodiments of the application is not intended to be limiting, but rather is intended to cover all modifications, equivalents, alternatives, and improvements that fall within the spirit and scope of the application.
