Abstract

The invention belongs to the technical field of earth-rock blasting, and particularly relates to drilling equipment for earth-rock blasting. The drilling equipment comprises a traveling platform, a pendulum bob mechanism, an adjusting mechanism and a hole drill, one end of a gear adjusting block is step-shaped, each step corresponds to a gear, if the gear adjusting block is adjusted, when an impact block is matched with one step face, after the impact block is stressed, a fourth spring is extruded firstly, then the gear adjusting block is impacted, part of impact force is transmitted to the hole drill through the gear adjusting block to impact and crush a hard layer, and residual energy is converted into pressure of impact on the hard layer, and the hard layer is subjected to rotary cutting by utilizing the pressure. The design aims to select impact force and drilling pressure distribution according to stone mountains with different hardness.

Description

[0001] Technical field

[0002] The invention belongs to the technical field of earth-rock blasting, in particular to a drilling device for earth-rock blasting. Background technique

[0003] During the construction of the mining area, when encountering hard soil or stone layers that cannot be constructed by conventional excavation equipment, drilling and blasting is required. For small-scale and low-cost construction, the demand for blasting is relatively sudden. At this time, large-scale equipment is seconded for drilling preparations. The time is longer and the cost is higher, so it is necessary to design a small and portable drilling equipment.

[0004] The present invention designs a kind of drilling equipment used for earthwork blasting to solve the above problems. Contents of the invention

[0005] In order to solve the above-mentioned defects in the prior art, the present invention discloses a drilling equipment for earthwork blasting, which is realized by adopting t...
