Background
When building on the ground, need pile on the ground, cement stirring stake is soft basic equipment of handling in the foundation engineering construction, use cement as the principal agent of curing agent, utilize stirring stake to spout cement into the soil body and intensive mixing, make cement and earth take place a series of physical and chemical reactions, the weak soil induration reaches the intensity that provides the ground, and the inside soil layer structure of ground distributes diversely, when the rock layer appears in the soil layer structure, because the hardness of the soil body, frictional resistance is great, make ordinary drill bit structure be difficult to effectual drilling, efficiency is lower.
SUMMERY OF THE UTILITY MODEL
Utility model purpose: the drilling bit suitable for multiple geologies is provided to solve the problems existing in the prior art.
The technical scheme is as follows: the utility model provides a creep into drill bit suitable for many geologies, includes the drilling rod, sets up the drill bit in the drilling rod bottom, the drill bit both sides are equipped with the fixed block, and the slope is equipped with the shifting block on two fixed blocks, two the incline direction of shifting block is two towards both sides around the drill bit respectively the angle that forms between shifting block and the drill bit is alpha.
Through adopting above-mentioned technical scheme, through set up the shifting block in the slope of drill bit both sides and with the drill bit between form angle, when the pile, utilize two shifting blocks to pull apart the rock that the drill bit was minced and hard soil, prevent that rubble and hard soil from blockking near the drill bit and leading to the drill bit to be difficult to creep into, improve pile efficiency.
Preferably, the thickness of the end a of each of the two shifting blocks is larger than that of the end b of each of the two shifting blocks, and the end b of each of the two shifting blocks is provided with a cutting edge.
Preferably, two helical blades are arranged on the outer side of the drill rod, the bottom ends of the two helical blades are located at the top ends of the fixed blocks corresponding to the helical blades, and the bottom ends of the two helical blades are welded with the a ends of the shifting blocks corresponding to the helical blades respectively.
Preferably, the angle alpha formed between the two shifting blocks and the drill bit is 50-60 degrees.
Preferably, a plurality of grooves are uniformly formed in the edges of the two spiral blades, a blade is arranged in each groove, and a groove corresponding to the blade extends out of the cutting edge end of each blade.
Has the beneficial effects that: through set up the shifting block in the slope of drill bit both sides and with form the angle between the drill bit, when the pile, utilize two shifting blocks to spread the rock that the drill bit was minced and hard soil, prevent that rubble and hard soil from blockking up near the drill bit and leading to the drill bit to be difficult to creep into, improve pile efficiency.

Detailed Description
In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. It will be apparent, however, to one skilled in the art, that the present invention may be practiced without one or more of these specific details. In other instances, well-known features have not been described in order to avoid obscuring the present invention.
The utility model provides a creep into drill bit suitable for many geologies, as fig. 1 and fig. 2, includes drilling rod 1, sets up drill bit 11 in drilling rod 1 bottom, and drill bit 11 both sides are equipped with fixed block 2, and two fixed block 2 slope are equipped with shifting block 21, and the incline direction of two shifting blocks 21 is the angle alpha that forms between two shifting blocks 21 and the drill bit 11 towards the front and back both sides of drill bit 11 respectively.
As shown in fig. 1 and 2, since the two blocks 21 are obliquely arranged on both sides of the drill bit 11 and form an angle with the drill bit 11, the rock and hard soil cut by the drill bit 11 are separated by the two blocks 21 during driving, thereby preventing the drill bit 11 from being difficult to drill due to the crushed stone and hard soil being blocked near the drill bit 11 and improving the driving efficiency.
As shown in fig. 2, the thickness of the end a of each of the two shifting blocks 21 is greater than that of the end b, and the end b of each of the two shifting blocks 21 is provided with a cutting edge, so that in the drilling process of the drill bit 11, the crushed stone and the hard soil are squeezed and compacted by the rotating force of the drill bit 11, and at this time, the compacted crushed stone and hard soil are crushed again by the cutting edge at the end b of each of the two shifting blocks 21, thereby facilitating the discharge of the crushed stone and the hard soil.
As shown in fig. 1 and 2, two helical blades 3 are arranged on the outer side of the drill rod 1, the bottom ends of the two helical blades 3 are located at the top ends of the fixing blocks 2 corresponding to the two helical blades 3, the bottom ends of the two helical blades 3 are respectively welded with the a ends of the shifting blocks 21 corresponding to the two helical blades 3, and the two helical blades 3 are driven by the drill bit 11 to rotate simultaneously so as to discharge broken stones and hard soil.
As shown in fig. 2, an angle α formed between the two shifting blocks 21 and the drill bit 11 is 50 to 60 °, an angle formed between the shifting blocks 21 and the drill bit 11 is too large to play a role of shifting broken stones and hard soil near the drill bit 11, an angle formed between the shifting blocks 21 and the drill bit 11 is too small, the shifted broken stones and hard soil are too much, the two helical blades 3 cannot be timely discharged, and the broken stones and the hard soil are accumulated on the surfaces of the two helical blades 3 and on the pile wall and are stuck.
As fig. 3, evenly be equipped with a plurality of recess 31 on two helical blade 3's the border, each recess 31 is inside to be equipped with blade 32, the cutting edge end of each blade 32 extends rather than the recess 31 that corresponds, the in-process of two helical blade 3 simultaneous rotations of drive that drill bit 11 drills, the cutting edge cuts rubble and hard soil this moment, reduce two helical blade 3 and rubble, the frictional force between the hard soil, prevent that two helical blade 3 from appearing blocking along with drill bit 11 drills in-process, improve and creep into efficiency.
The working principle is as follows: set up shifting block 21 and with the formation of angle between the drill bit 11 in the slope of drill bit 11 both sides, drive two shifting blocks 21 and rotate when the drill bit 11 drills, break away the rock that the drill bit 11 was minced with hard soil, simultaneously when the drill bit 11 drills, the drill bit 11 is rotatory to produce the revolving force, rubble and hard soil receive the revolving force of drill bit 11 and receive the extrusion compaction, utilize shifting block 21b end cutting edge to carry out the recrushment to compacted rubble and hard soil this moment, two helical blade 3's rotation is discharged rubble and hard soil this moment, and then prevent that rubble and hard soil from blockking near drill bit 11 and leading to the drill bit 11 to be difficult to creep into, improve pile efficiency.
The preferred embodiments of the present invention have been described in detail with reference to the accompanying drawings, however, the present invention is not limited to the details of the above embodiments, and the technical concept of the present invention can be modified to perform various equivalent transformations, which all belong to the protection scope of the present invention.
