Embodiment Construction
[0017] The specific embodiment of impact punching machine of the present invention is as figure 1 , figure 2 , image 3 As shown, the percussion drilling machine is mainly composed of a percussion drill 1 and a driving mechanism for driving the percussion drill 1 to reciprocate linearly in the vertical direction. Wherein, the lower end of the percussion drill 1 is integrally provided with an impact head 4 for crushing stones, and the upper end of the percussion drill 1 is extended and fixed with a concentrically arranged drill rod 3 , and a helical screw is also coiled on the outer peripheral surface of the percussion drill 1 . Fin 2, in this embodiment, the impact head 4 is composed of more than three sharp impact teeth evenly distributed around the circumference, the spiral fin 2 is provided with at least two sections, and the front and back of each spiral fin 2 are not connected, the spiral The ribs 2 can ream the hole when punching on the one hand, and can suppress the ...

The invention discloses an impact perforating machine. The impact perforating machine is characterized in that a revolved body and a support body are arranged on a frame, wherein a rotating axis of the revolved body extends in the horizontal direction under the drive of a corresponding drive mechanism; the support body is matched with the revolved body to intermittently clamp and drive a drilling rod to ascend; the revolved body is provided with a peripheral edge; the support body is provided with support parts corresponding to the peripheral edge of the revolved body and arranged at intervals; a drilling rod clearance for the drilling rod to pass through vertically is formed between the peripheral edge of the revolved body and the support parts of the support body; a clamp fit part and a clearance fit part are arranged at the peripheral edge of the revolved body; the clamp fit part is fit with the corresponding support part of the support body when the revolved body rotates to ensure that the drilling rod clearance is not less than the external diameter of the drilling rod so as to clamp the drilling rod; and the clearance fit part is used to ensure that the drilling rod clearance is greater than the external diameter of the drilling rod so as to release the drilling rod. The impact perforating machine is simple in structure, convenient in use, has the characteristics of light weight, low manufacturing cost, easiness in mounting and dismounting and the like, and can be widely applied to industrial and agricultural well drilling, as well as basic bore drilling projects in building construction and bridge construction.
Description
technical field [0001] The invention relates to an impact drilling machine used for drilling holes on the ground in engineering construction. Background technique [0002] The drilling equipment commonly used at present mainly adopts the auger drilling machine, but the auger drilling machine can only be used for drilling in the soil layer, and it cannot be used in areas where the soil quality is relatively complicated. Chinese Invention Patent Publication Document CN201671531U discloses an engineering percussion drilling rig. This percussion drilling rig uses a hoist to suspend the impact drill bit by passing around the sky beam mast extending upward through a steel wire rope. Falling freely under its own weight crushes rocks. But this kind of engineering percussion drilling rig has complex structure, high cost, and its volume is relatively large, so it is difficult to enter narrow places such as river courses and ditches. Contents of the invention [0003] The object of...
