[0024] Specific examples are given below.

[0025] like Figures 1 to 5As shown, a dark excavation rock crushing device described in an embodiment of the present invention includes a rock crusher body 1, the middle part of the rock crusher body 1 is rotatably connected to a first rotating seat 11; the middle part of the first rotating seat 11 is rotatably connected to an extension arm 13; a power assembly 12 is installed on the surface of the rock crusher body 1; a crushing assembly 14 is provided at the end of the extension arm 13; a crushing head 15 is provided inside the crushing assembly 14; a plurality of circular plates 16 are rotatably connected to the bottom of the rock crusher body 1; a first damping spring 17 is fixedly connected to the bottom of the circular plate 16; a fixed plate 18 is fixedly connected to the bottom of the first damping spring 17; the side wall of the fixed plate 18 is rotatably connected to the wheel 19; when working, the power assembly 12 is first used to drive the wheel 19 to rotate, thereby pushing the rock crusher body 1 to move as a whole. When the wheel 19 enters the underground and encounters a pothole, the first damping spring 17 will apply thrust to the fixed plate 18 when the wheel 19 enters the pothole. At this time, the fixed plate 18 will bring The moving wheel 19 moves down and enters the pothole and contacts the edge of the pothole. When the wheel 19 contacts the pothole, it provides support for the rock crusher body 1, thereby reducing the overall tilt of the rock crusher body 1. Subsequently, when the wheel 19 leaves the pothole, the first damping spring 17 will be compressed to adjust the overall stability of the rock crusher body 1. When it reaches the specified position, the first rotating seat 11 and the extension arm 13 can be controlled by the power component 12 to move the crushing component 14 to the rock surface, and then the crushing component 14 is started to drive the crushing head 15 to crush the rock; by adding the first damping spring 17, the wheel 19 can be quickly dropped to the ground when the wheel 19 passes through the pothole, thereby reducing the tilt angle of the rock crusher body 1, thereby increasing the stability of the rock crusher body 1 when moving, and reducing the shaking of the rock crusher body 1 when moving underground. At the same time, the first damping spring 17 can absorb the vibration generated by the crushing head 15 during operation when the crushing head 15 crushes the rock, thereby reducing the damage to internal parts caused by vibration.

[0026] like Figures 1 to 2As shown, a pair of second rotating seats 2 are fixedly connected to the side walls of the rock crusher body 1; a fixed rod 21 is rotatably connected to the middle of the second rotating seat 2; the fixed rod 21 and the second rotating seat 2 are connected by a torsion spring; a baffle 22 is fixedly connected to the end of the fixed rod 21; when working, when the crushing head 15 crushes the rock, the rock will roll down along the stone body after becoming small particles, and at this time the baffle 22 will block these rocks for the rock crusher body 1, thereby reducing the direct contact between the rock and the rock crusher body 1, so that the rock reduces the impact on the rock crusher. The impact of the main body 1 increases the protection of the crushing head 15 when crushing the rock. At the same time, when the rock crusher main body 1 moves, the baffle 22 collides with the ground object in front, and the fixed rod 21 can also adjust the height of the baffle 22, and then it will recover due to the force of the torsion spring; by adding the baffle 22, the protection can be increased when the crushing head 15 crushes the rock, so that the rock that rolls down after the crushing head 15 breaks the rock is blocked by the baffle 22, thereby providing protection for the rock crusher main body 1 and reducing the impact damage of the rock on the rock crusher main body 1.

As the square plate 31 hits, the second damping spring 3 is compressed, thereby reducing the force exerted on the square plate 31, thereby weakening the force of the rock impact. At the same time, after the square plate 31 blocks the rock for the crushing assembly 14, the protection of the crushing assembly 14 and the rock during close operation is reduced, thereby reducing the impact of the rock on the crushing assembly 14; by adding the square plate 31, the splashing rock can be blocked for the crushing assembly 14, thereby increasing the protection of the crushing assembly 14, and at the same time, the impact force exerted on the square plate 31 will be absorbed by the compression of the second damping spring 3, thereby reducing the impact force of the rock on the square plate 31 when the square plate 31 blocks the rock.

[0028] like Figures 1 to 2 As shown, a plurality of hydraulic cylinders 4 are installed at the bottom of the rock crusher body 1; the hydraulic cylinders 4 are arranged in a triangle; a support plate 41 is hinged at the bottom of the hydraulic cylinder 4; during operation, when the rock crusher body 1 needs to operate on an area for a long time, the hydraulic cylinder 4 can be extended to make the support plate 41 contact the ground, and when the support plate 41 contacts the ground, it will automatically rotate and adapt to the ground. When the support plate 41 is completely in contact with the ground, the rock crusher body 1 will be raised as a whole, thereby erecting the rock crusher body 1, so that the rock crusher body 1 increases stability during long-term operation; by adding the hydraulic cylinder 4, support can be provided for the rock crusher body 1 when it stays for a long time, thereby increasing stability during operation, and at the same time, the triangle has higher stability, thereby reducing shaking during long-term operation.

[0029] like Figures 1 to 5 As shown, a shovel plate 5 is fixedly connected to the side wall of the second rotating seat 2; the surface of the shovel plate 5 is set as an inclined surface; during operation, when the rock crusher body 1 needs to continue to go deeper after processing an area, the end of the shovel plate 5 will first contact the ground rock and shovel it up; by adding the shovel plate 5, the rocks on the path can be reduced during the movement of the rock crusher body 1 after operation, thereby reducing obstacles, and at the same time, the inclined surface of the shovel plate 5 can reduce the resistance when the rock moves.

When the wheel 19 enters the underground and encounters a pothole, the first damping spring 17 will apply a thrust to the fixed plate 18 when the wheel 19 enters the pothole. At this time, the fixed plate 18 will drive the wheel 19 to move downward, thereby entering the pothole and contacting the edge of the pothole. When the wheel 19 contacts the pothole, it will provide support for the rock crusher body 1, thereby reducing the overall tilt of the rock crusher body 1. Then, when the wheel 19 leaves the pothole, the first damping spring 17 will be compressed to adjust the overall stability of the rock crusher body 1. When it reaches the designated position After that, the first rotating seat 11 and the extension arm 13 can be controlled by the power assembly 12 to move the crushing assembly 14 to the rock surface, and then the crushing assembly 14 is started to drive the crushing head 15 to crush the rock; when the crushing head 15 is crushing the rock, the rock will roll down along the stone body after becoming small particles, and at this time, the baffle 22 will block these rocks for the rock crusher body 1 to reduce the direct contact between the rock and the rock crusher body 1, so that the rock reduces the impact of the rock crusher body 1, thereby increasing the protection of the crushing head 15 when crushing the rock, and at the same time, when the rock crusher body 1 is moving, the baffle 22 collides with the ground object in front The height of the baffle 22 can also be adjusted, and then it will be restored due to the force of the torsion spring; when the crushing head 15 crushes the rock, some of the rock will splash due to the vibration during the crushing, and the splashing rock will come into contact with the square plate 31. As the square plate 31 hits, the second damping spring 3 is compressed, thereby reducing the force exerted on the square plate 31, thereby weakening the force of the rock impact. At the same time, after the square plate 31 blocks the rock for the crushing assembly 14, it can reduce the protection of the crushing assembly 14 and the rock when working in close proximity, thereby reducing the impact of the rock on the crushing assembly 14; when the rock crusher body 1 needs to operate on an area for a long time, the hydraulic cylinder 4 can be extended so that the support plate 41 and Ground contact. When the support plate 41 contacts the ground, it will automatically rotate and adapt to the ground. When the support plate 41 is completely in contact with the ground, the rock crusher body 1 will be lifted as a whole, thereby erecting the rock crusher body 1, so that the rock crusher body 1 increases stability during long-term operation; when the rock crusher body 1 needs to continue to go deeper after processing an area, the end of the shovel plate 5 will first contact the ground rock and shovel it up; when the rock crusher body 1 moves, the rock will be separated by the end of the partition plate 6 and move to the guide plates 61 on both sides, and then will move to both sides of the path through the surface of the guide plate 61, thereby reducing the rock on the surface of the shovel plate 5 in the cleaning moving path.
