DETAILED DESCRIPTION

[0036] The following is combined with Figure 1-3 This application is described in further detail.

[0037] The present application discloses an improved vibration reduction device for rock drilling in mountainous areas. Figure 1 A vibration reduction and improvement device for rock drilling in mountainous areas includes a feed beam 100, which is a rectangular parallelepiped structure; a support mechanism 400 is installed at the lower end of the feed beam 100, and the feed beam 100 is connected to the ground through the support mechanism 400. A connecting mechanism 300 is installed on the side wall of the feed beam 100, and the connecting mechanism 300 is used to fix the drilling machine, and the drill bit of the drilling machine is parallel to the length direction of the feed beam 100. A driving mechanism 200 is also installed on the feed beam 100, and the driving mechanism 200 drives the connecting mechanism 300 to move along the length direction of the feed beam 100, so as to drill the rock.

By hingedly connecting the feed beam 100 and the support 410, before drilling, the angle between the feed beam 100 and the ground is adjusted according to the drilling direction. After the feed beam 100 is adjusted, the two support rods 420 are rotated so that the end of the support rod 420 away from the feed beam 100 abuts against the ground, thereby fixing the feed beam 100.

A limiting assembly 320 for fixing the drilling machine is installed at one end of the slider 310 away from the ground. The limiting assembly 320 includes a connecting rod 321, which is inserted through the end of the slider 310 away from the ground, and the connecting rod 321 is slidably connected to the slider 310 along the length direction of the slider 310.

One end of the first spring 323 is fixedly connected to the end of the slider 310 away from the ground, and the end of the first spring 323 away from the slider 310 is fixedly connected to the inner ring of the bearing 324. The limit plate 322 abuts against the body of the drilling machine under the elastic force of the first spring 323, thereby fixing the drilling machine. When fixing the drilling machine, the nut 325 is rotated to adjust the pressure applied by the limit plate 322 to the drilling machine, and the drilling machine is easy to install.
