Example Embodiment

[0019] Example one

[0020] See Figure 1-2 , A rotary drilling machine for processing prefabricated pipe piles, comprising a drill rod 10, a first rotating motor 14, a drill bit 15. The top of the drill rod 10 is fixedly connected with a hydraulic cylinder for driving the drill rod 10 to move through the hydraulic rod 11. The drill pipe 10 is arranged in a cavity structure and a set of mounting frames 13 in a U-shaped structure are fixedly installed at the bottom of the drill pipe 10, and a set of first rotating motors 14 are fixedly mounted on the inside of the U-shaped opening on the lower side of the mounting frame 13. The exterior of the electric motor 14 is provided as a stainless steel housing for improving the safety of the first rotating electric machine 14. The lower output end of the first rotating motor 14 is rotatably connected with a set of rotating shafts 16. The bottom of the rotating shaft 16 is fixedly installed with a drill 15 through a mounting plate. The dri...

Example Embodiment

[0021] Example two

[0022] See Figure 3-4 On the basis of the first embodiment, the lower outer side wall of the waste straw 18 is provided with a second rotating motor 23, and the bottom of the second rotating motor 23 is fixed on the outer side wall of the waste straw 18 through a support plate. The output end of 23 faces the inside of the waste suction tube 18 and is rotatably connected with a shift roller 25 provided inside the waste suction tube 18 through a rotating rod. The connection between the rotation rod and the side wall of the waste suction tube 18 is provided to prevent the gas inside the waste suction tube 18. Vented seal 27. By activating the second rotating motor 23, the shift roller 25 is directly driven to rotate inside the waste suction pipe 18. The outer side of the shift roller 25 is fixedly installed with multiple sets of arc-shaped shift plates 26 at equal intervals. Rotating the direction of rotation of the motor 23 drives the pick-up plate 26 to rot...

Abstract

The invention relates to the technical field of prefabricated pipe pile machining and manufacturing, and discloses a rotary boring machine for prefabricated pipe pile machining. The rotary boring machine comprises a drill rod, a first rotary motor and a drill tool, the top of the drill rod is fixedly connected with a hydraulic cylinder used for driving the drill rod to move through a hydraulic rod, the drill tool is arranged to be a hobbing cutter with the top of a conical structure, multiple sets of material suction openings of horn-shaped structures are formed in the lower surface of a mounting plate on the upper side of the drill tool by a circle in an opening-and-closing mode, and the tops of the material suction openings upwards communicate with waste suction pipes with the top ends stretching into the drill rod; and a set of waste discharge pipes of an L-shaped structure are arranged in the middle of the interior of the drill rod, vertical sections of the waste discharge pipes are arranged in the drill rod, transverse sections of the waste discharge pipes penetrate through the right side of the drill rod and extend outwards, and the tops of the waste suction pipes communicatewith the bottom ends of the waste discharge pipes. The rotary boring machine has the advantages of being high in drilling speed and efficiency, environmentally friendly and easy to operate.

Description

technical field [0001] The invention relates to the technical field of processing and manufacturing prefabricated pipe piles, in particular to a rotary drilling machine for processing prefabricated pipe piles. Background technique [0002] Prefabricated pipe piles: There are mainly two categories: concrete prefabricated piles and steel piles. Concrete prefabricated piles can withstand large loads, are strong and durable, and have fast construction speed. They are one of the widely used pile types, but their construction has a great impact on the surrounding environment. Commonly used concrete solid square piles and prestressed concrete hollow pipe piles . [0003] When the existing prefabricated pipe piles are processed and manufactured, the most critical step is to drill the holes after pouring and cooling. The existing drilling machines will generate a lot of dust during the drilling process, and the prefabricated The inside of the pipe pile is easy to accumulate a large...
