Abstract
The utility model disclose a drill-bit of a mixing pile machine, comprising a drill rod, and the front end of the drilling rod is provided with a spiral cutter plate, and the spiral cutter plate presents a spiral distribution at the drill rod, meanwhile, the spiral cutter plate is also provided with a plurality of cutter heads, and the cutter heads are distributed at the outer edge of the spiral cutter plate. The inner side of the spiral cutter plate is welded with the drill rod. The cutter heads are evenly distributed at the outer side of the spiral cutter plate and are welded with the outer side of the spiral cutter plate. During piling, the drill rod rotates to drive the cutter plate to rotate, the cutter head on the cutter plate downward shovels soil, that is, the piling and the drilling can be conducted.
Description
Technical field
The utility model relates to construction engineering technical field, the concrete drill bit of using on a kind of mixing pile machine that relates to.
Background technology
Operated by rotary motion has drilling rod on the mixing pile machine, and drilling rod is used for piercing soil layer downwards.Front end at drilling rod is provided with drill bit, and drill bit is provided with cutter head, and cutter head shovel soil is broken when probing like this, and drilling rod just can pierce downwards.
But the drill bit of the drilling rod front end of mixing pile machine is generally outsourcing piece or finished parts in the prior art, drill bit in use is difficult to maintenance if cutter head damages, if in case and cutter head damage drilling rod and work on and also can drive all the other cutter heads and damage, thereby influence normal piling work.
The utility model content
Technical problem to be solved in the utility model is, overcomes problems of the prior art, and a kind of mixing pile machine drill bit is provided.
In order to address the above problem the technical solution of the utility model is such:
A kind of mixing pile machine drill bit comprises a drilling rod, and the front end of described drilling rod is provided with the spiral knife plate, and described spiral knife plate is shape distribution in the shape of a spiral on drilling rod, also is provided with some cutter heads on the described spiral knife plate, and described cutter head is distributed in the outward flange of spiral knife plate.
The inboard of described spiral knife plate and drilling rod welding.
Described cutter head is evenly distributed on the outside of spiral knife plate and welds with the outside of spiral knife plate.
During piling, drilling rod rotates, and drives knife plate and rotates together, and the cutter head on the knife plate shovels soil downwards, the brill of can driving piles down.
Beneficial effect, drill bit design described in the utility model is reasonable, is easy to down bore, and can in time change when cutter head on the drill bit damages, and has effectively guaranteed the quality and the progress of construction.
Description of drawings
Describe the utility model in detail below in conjunction with the drawings and specific embodiments;
Fig. 1 is the structural representation of mixing pile machine drill bit described in the utility model;
Fig. 2 is the upward view of Fig. 1.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
Referring to Fig. 1 and Fig. 2
Drill bit described in the present embodiment comprises a drilling rod 1, drilling rod 1 is rotatable pierce underground, the front end of drilling rod 1 is provided with a plurality of knife plates 2, knife plate 2 is the spiral knife plate, and the spiral knife plate is that the knife plate body has spiral helicine rotational structure, and knife plate 2 is shape distribution in the shape of a spiral on drilling rod 1.And the direction of spiral is identical with the direction of drilling rod 1 rotation.The inboard of knife plate 2 and drilling rod 1 weld together, and concrete welding manner is a gas shielded arc welding.
The helical form knife plate 2 of drilling rod 1 front end is provided with several cutter heads 3, and described cutter head 3 is distributed in the outer ledge of knife plate 2, and cutter head 3 evenly distributes on knife plate 2, the point of a knife of cutter head 3 down and cutter head 3 relative horizontal planes inclined so that brill down.And arrange in the direct vertical level of the forefront top of drilling rod 2 cutter head.Be welded to each other together between cutter head 3 and the knife plate 2, concrete welding manner is a gas shielded arc welding.The diameter that the drill bit that drilling rod 1 knife plate 2 and cutter head 3 are formed can be holed is 850mm.Certainly the size of adjusting knife plate 2 also can further be adjusted the diameter of boring.
To understand underground whether have concrete, stone during construction.When boring, note observing under construction, the sound that notes abnormalities and when rocking answers hard stop to pull up drilling rod, is used for the obstruction of digging machine below clear, prevents the drilling rod that bends, and interrupts drill bit.The cutter head of drilling rod front end is a consumable accessory in addition, finds serious wear, interrupts, comes off, and should in time change soldering.Prevent that boring from diminishing and influence construction quality, prevent from may wear to knife plate and be difficult to repair.
More than show and described basic principle of the present utility model, principal character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the manual just illustrates principle of the present utility model; the utility model also has various changes and modifications under the prerequisite that does not break away from the utility model spirit and scope, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
Claims (3)
1. a mixing pile machine drill bit comprises a drilling rod, and the front end of described drilling rod is provided with the spiral knife plate, and described spiral knife plate is shape distribution in the shape of a spiral on drilling rod, also is provided with some cutter heads on the described spiral knife plate, and described cutter head is distributed in the outward flange of spiral knife plate.
2. a kind of mixing pile machine drill bit according to claim 1 is characterized in that, the inboard of described spiral knife plate and drilling rod welding.
