[0025] In this embodiment: the support assembly includes a base 101, a support slope 103 is provided on the front end of the base 101, three slide grooves 102 are evenly opened behind the support slope 103, a support plate 105 is provided on the front side of the three slide grooves 102, three ribs 106 are evenly provided between the support plate 105 and the base 101, twelve ground piles 104 are evenly provided under the base 101, and the bottom shape of the ground pile 104 is conical. When in use, the base 101 is fixed by inserting the ground through the ground pile 104, the support slope 103 at the rear end of the base 101 enhances the supporting force of the base 101 against rear impact, the rib 106 enhances the supporting capacity of the support plate 105 against rear impact, and the slide groove 102 is used to fix the buffer assembly;

[0026] In this embodiment, the blocking assembly includes a positive baffle 201, six first damping rods 204 are evenly arranged in front of the positive baffle 201, a first spring 205 is arranged outside the first damping rod 204, an upper baffle 202 is arranged on the top of the positive baffle 201, the upper baffle 202 is inclined, a rotating shaft 203 is installed between the positive baffle 201 and the upper baffle 202, the positive baffle 201 and the upper baffle 202 are hinged together through the rotating shaft 203, an elastic plate 206 is arranged under the upper baffle 202, and the upper baffle 202 is provided with a plurality of springs 206. 02 The inclination angle is 30 degrees. The elastic plate 206 is in an arc shape. When the slope collapses, the positive baffle 201 blocks the rolling stones from the rear. At the same time, the first spring 205 cooperates with the first damping rod 204 to buffer the impact of the rolling stones. The falling stones fall onto the upper baffle 202 and are blocked by the inclined upper baffle 202 to the rear of the device. At this time, the upper baffle 202 rotates around the rotating shaft 203 under the support of the positive baffle 201 and presses down the elastic plate 206 to initially buffer the impact of the falling stones.

The connecting rod 301 is tilted and the tilt angle is sixty degrees. When the falling rock falls on the upper baffle plate 202, the upper baffle plate 202 presses the connecting rod 301 downward through the first hinge seat 302, so that the connecting rod 301 pushes the slider 304 in the slide groove 102 through the second hinge seat 303 to compress the second damping rod 305 and the second spring 306 forward to form a secondary buffer.

[0028] Working principle: When in use, the base 101 is fixed by inserting the ground pile 104 into the ground, the supporting slope 103 at the rear end of the base 101 enhances the supporting force of the base 101 against the rear impact, and the rib plate 106 enhances the supporting ability of the support plate 105 to the positive baffle 201; when the slope collapses, the positive baffle 201 blocks the rolling stones from the rear, and the first spring 205 cooperates with the first damping rod 204 to buffer the impact of the rolling stones; the falling stones fall to the upper baffle 20 2, and is blocked by the inclined upper baffle 202 and falls to the rear of the device. At this time, the upper baffle 202 rotates around the rotating shaft 203 under the support of the positive baffle 201 and presses down the elastic plate 206 to initially buffer the impact of the falling rocks. At the same time, the upper baffle 202 presses down the connecting rod 301 through the first hinge seat 302, so that the connecting rod 301 pushes the slider 304 in the slide groove 102 through the second hinge seat 303 to compress the second damping rod 305 and the second spring 306 forward, thereby forming a secondary buffer.
