Abstract
Provided is a spiral hole forming machine of a cast-in-place pile. A plurality of sections of extension bars are arranged at the upper end of a motor and are connected through a fast joint, a triangular cutter is respectively arranged on the left side and the right side of a lower end cover of the motor, the output shaft end of the motor is connected with a screw, the lower end of the screw is connected with a retaining block, and the lower end of the retaining block is connected with a rotary cutting drill A. A rotary cutting drill B is arranged on the screw and comprises a nut 6 screwed on the screw and four connection rods with the upper ends fixed on the nut, the lower end of each connection rod is fixed at the lower end of a slanting rod, the upper end of each slanting rod is fixed on a round support, and a plurality of cutter heads are arranged on the four slanting rods. The spiral hole forming machine can clean mud on the drills by reversely rotating the screw and lifting the drills, and inconvenience caused by the fact that the drills are lifted out of holes is avoided.
Description
Technical field
The utility model relates to a kind of hole forming machine, the castinplace pile spiral hole forming machine that particularly uses in a kind of underground concrete Pile Grouting.
Background technology
At present, the earth method therefor that the hole forming machine that uses in the underground concrete Pile Grouting is removed on drilling tool proposes drilling tool to carry out outside the hole.
Summary of the invention
The utility model has made up above shortcoming, and a kind of castinplace pile spiral hole forming machine is provided.
The utility model is achieved by the following technical solution:
A kind of castinplace pile spiral hole forming machine, motor upper end are provided with extension bar, and the more piece extension bar connects by snap joint, motor bottom end cover the right and left is respectively equipped with a triangular knife, the motor output shaft end is connected with screw rod, and the screw rod lower end is connected with block, and the block lower end is connected with rotary-cut drilling tool A; Screw rod is provided with rotary-cut drilling tool B, rotary-cut drilling tool B comprises: be screwed in the nut 6 on screw rod, four connecting rods of nut are fixed in the upper end, and each connecting rod lower end is individually fixed in oblique bar lower end, each oblique bar upper end is individually fixed in circular support, and four oblique bars are provided with a plurality of cutter heads.
The utlity model has following beneficial effect:
The utility model can be removed the earth on drilling tool by counter-rotating screw rod rising drilling tool, avoids drilling tool is proposed the inconvenience that brings outside the hole.
Description of drawings
Below in conjunction with accompanying drawing, the utility model is further described;
Accompanying drawing 1 is structural representation of the present utility model;
Accompanying drawing 2 is A-A view.
In figure: 1, extension bar, 2, snap joint, 3, motor, 4, triangular knife, 5, screw rod, 6, nut, 7, circular support, 8, connecting rod, 9, oblique bar, 10, cutter head, 11, block, 12, rotary-cut drilling tool A.
The specific embodiment
Accompanying drawing is a kind of specific embodiment of the present utility model, this embodiment motor 3 upper ends are provided with extension bar 1, the more piece extension bar connects by snap joint, motor bottom end cover the right and left is respectively equipped with a triangular knife 4, the motor output shaft end is connected with screw rod 5, the screw rod lower end is connected with block 11, and the block lower end is connected with rotary-cut drilling tool A12; Screw rod is provided with rotary-cut drilling tool B, rotary-cut drilling tool B comprises: be screwed in the nut 6 on screw rod, four connecting rods 8 of nut are fixed in the upper end, and each connecting rod lower end is individually fixed in oblique bar 9 lower ends, each oblique bar upper end is individually fixed in 7, four oblique bars of circular support and is provided with a plurality of cutter heads.
In the utility model work, during motor-driven screw rod forward, rotary-cut drilling tool B moves down, when moving to stop location, and rotary-cut drilling tool A together, the pore-creating of rotary-cut soil layer, when sticking with paste brill, the counter-rotating of motor-driven screw rod is so rotary-cut drilling tool B climbs along screw rod, arrival triangular knife position, triangular knife is relatively static due to rotary-cut drilling tool B rotation, so triangular knife is removed the earth on rotary-cut drilling tool B.
