Drilling rig on excavator with breaker

Abstract

A drilling machine provided with a crushing hammer and used on an excavator comprises a hinge, a slide way, a slide way oil cylinder, a slide block, a drilling machine body, a support and a rock splitting pipe. The slide way is connected to the bucket arm side face of the excavator. The slide way oil cylinder is installed between the slide way and the bucket arm side. The slide block is installed on the slide way. The drilling machine body is installed on the support on the slide block. The rock splitting pipe is put in a pipe casing arranged on the drilling machine body. A motor, a reel and a pull rope are arranged at the upper end of the drilling machine body, and the rock splitting pipe is controlled to drop down and be lifted. Two bucket arm oil cylinders are installed on two side faces of the bucket arm. When the crushing hammer works, the drilling machine body moves up with the slide block and is locked. During drilling, the breaking hammer is folded and put away, the slide way oil cylinder controls the slide way to rotate at a set angle, and the drilling machine body slips down with the slide block. After drilling, a drill rod is lifted, the slide way rotates at a set angle, and the rock splitting pipe is put down to perform splitting operation. The drilling machine integrates drilling, putaway of the rock splitting pipe for rock splitting and rock impacting and breaking, the drilling machine and the breaking hammer are not required to be taken down and replaced, and a user does not need to take and put down a rock splitting device, and the drilling machine is convenient and quick to use.

Description

technical field [0001] The invention belongs to the field of engineering machinery, in particular to a drilling rig on an excavator with a breaking hammer. Background technique [0002] Nowadays, in field, mine, and tunnel construction, a drilling rig is often installed on the bucket arm of the excavator. After drilling holes in the rock, the ground workers lift the hydraulic blasting pipe, that is, insert the rock splitting pipe into the hole, and wait for the rock to be split. , Take out the rock splitting pipe, and finally use the breaker installed on the bucket arm of the excavator to impact the split large rock into small pieces of appropriate size. This has resulted in, on the one hand, drilling with a drilling rig, manually placing and collecting the rock-splitting pipe, and impacting with the breaker, which requires three working links, and two excavators are required to install the breaker and the drill respectively, or one excavator first It is necessary to remove...

Problems solved by technology

This has resulted in, on the one hand, drilling with a drilling rig, manually placing and collecting the rock-splitting pipe, and impacting with the breaker, which requires three working links, and two excavators are required to install the breaker and the drill respectively, or one excavator first It is necessary to remove the breaking hammer and install the drilling rig. After the drilling is completed, the drilling rig has to be removed and the breaking hammer is reinstalled. It takes a lot of time and affects work efficiency.

On the other hand, when the rock splitting pipe splits a large volume of rock, some of them can be scattered by the impact of the hammer, and some large rocks are very laborious to be impacted by the hammer, and the continuous impact time is too long, which will cause damage to the hammer.
