Abstract
The utility model relates to a spiral drilling bucket used for construction of a construction site, in particular to a large-scale dual spiral drilling bucket specially used for loosening soil property. Two blades of the spiral drilling bucket are fixedly arranged on a double thread screw symmetrically, and a plurality of cutting picks are fixedly arranged on the blades. Compared with the prior art, the long screw pitch combined type dual-cone dual-screw spiral drilling bucket has the advantages that the long screw pitch combined type dual-cone dual-screw spiral drilling bucket is convenient to weld, screw pitch of the spiral blades is increased to 1.2 meters to enable the distance between the blades of the dual spiral drilling bucket to be 600 millimeters, and therefore enough space is reversed for welding the blades; earth material excavation is improved, and dip angles of the cutting picks are increased to facilitate excavation of the earth materials; replacement of an abraded cutting pick is facilitated, when the abraded cutting pick needs to be replaced, the abraded cutting pick can be replaced simply by unscrewing an attachment bolt, and replacment of the abraded cutting pick is fast and convenient; cost is reduced, and due to the fact that the dual spiral drilling bucket only needs two blades and an ordinary dual spiral drilling bucket needs four blades, and production and processing cost of the drilling bucket is reduced.
Description
Technical field
The utility model relates to the used spiral drilling bucket of a kind of building site construction, especially a kind of large-scale double helix drilling bucket that is specifically designed to loose soil property.
Background technology
Revolve and dig the stake worker construction that drilling construction is the advanced person that develops rapidly in the recent period in China, many characteristics such as that the rotary drilling rig construction has is efficient, low noise, environmental protection, hole quality height, mechanization degree height.Rotary drilling rig is the executor of this worker's method, no matter be that external product or home equipment form of structure and operating principle are similar, but the stratum of constructing varies, the concrete technical requirements of constructing is had nothing in common with each other again, so have only by selecting different drill bits to satisfy above-mentioned requirement, scientifically select drill bit and reasonably use drill bit, can enrich the construction technology of rotary drilling rig to a certain extent, widen the construction field of rotary drilling rig.
At present, as shown in Figure 1, the pitch of the blade of the spiral drilling bucket on the market is all in 600mm, if the double helix drilling bucket blade pitch more than the picture 1500mm is in 600mm, the double helix drilling bucket has welded the distance of rear blade and blade just less than 300mm so, because blade and blade pitgh are less than 300mm, the space is less, bigger spiral drilling bucket is just very difficult when the welding blade, and such king bolt drilling bucket the time advances the soil difficulty in construction, therefore releases a kind of loose soil property with the two spiral shell spiral drilling buckets of long pitch combined type bipyramid.Compare with other forms of spiral drilling bucket, loose soil property lengthens with the pitch of the two spiral shell spiral drilling buckets of long pitch combined type bipyramid, there are enough spaces to be convenient to welding, and the setting angle of pick increases the digging be conducive to earth material, adopts Bolt Connection also be conducive to the to wear and tear replacing of pick between pick and the blade.
The two spiral shell spiral drilling buckets of the current this bipyramid that generally uses, manufacture difficulty is higher, be unfavorable for into soil simultaneously.Wherein the higher reason of manufacture difficulty is: the distance between double helix drilling bucket blade and the blade is too little, and relatively more difficult when being welded on blade on the screw rod, manufacturability is not good enough.Be unfavorable for that into the reason of soil is: the inclination angle of pick is too little on the spiral drilling bucket blade, and earth material is unfavorable for being peeled off, so drilling bucket is unfavorable for into soil.
The utility model content
The purpose of this utility model is in order to solve existing large-sized double helix drilling bucket welding difficulty, to advance native inconvenience and pick during construction and be unfavorable for problems such as installation and replacing, providing a kind of long pitch combined type bipyramid two spiral shell spiral drilling buckets.
The purpose of this utility model is achieved through the following channels: the two spiral shell spiral drilling buckets of a kind of long pitch combined type bipyramid, and the blade symmetry of two spiral drilling buckets is packed on the two-flight screw, and several picks are installed on the blade.
As the further optimization of this programme, the pitch between described two blades is 1200mm.
As the further optimization of this programme, the pick setting angle on the described blade is the 10-30 degree.
As the further optimization of this programme, the pick setting angle on the described blade is 30 degree.
As the further optimization of this programme, described pick by Bolt Connection on blade.
Compared with prior art, the beneficial effect of the two spiral shell spiral drilling buckets of the long pitch combined type of the utility model bipyramid is: 1, be convenient to welding, the pitch of helical blade is risen to 1.2 meters, and to make the distance between the double helix drilling bucket blade be 600mm, and therefore having reserved enough spaces removes to weld blade; 2, improve the earth material digging, the inclination angle of pick increases the digging of being convenient to earth material; 3, be convenient to the to wear and tear replacing of pick, when needs were changed the wearing and tearing pick, it was namely replaceable, efficient and convenient only to need to turn on attachment bolt; 4, reduced cost, this double helix drilling bucket only needs two blades, and common double spiral drilling bucket then needs 4 these blades, has therefore reduced the production and processing cost of drilling bucket.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described in further detail:
Fig. 1 is the two spiral shell auger bucket structure schematic diagrames of prior art bipyramid;
Fig. 2 is the two spiral shell auger bucket structure schematic diagrames of the long pitch combined type of the utility model bipyramid;
Among the figure, screw rod 1, blade 2, pick 3.
The specific embodiment
As shown in Figure 2, the two spiral shell spiral drilling buckets of the long pitch combined type of the utility model bipyramid, blade 2 symmetries of its two spiral drilling buckets are packed on the two-flight screw 1, pitch between described two blades 2 is 1200mm, the blade of double helix drilling bucket and the distance between the blade are 600 millimeters like this, there are enough spaces to weld, are convenient to production and processing.Several picks 3 are installed on the blade 2, and pick 3 setting angles are the 10-30 degree, are equivalent to increase the exploitation power to earth material when working in loose soil property, conveniently advance soil when therefore constructing.Described pick by Bolt Connection on blade 2, namely weld bolt is used for fixing on blade, and the corresponding machining screw of the fixed end of pick connects by nut between set bolt and the pick then, it is replaceable, very convenient only need to back out bolt when installation or replacing pick.
