Abstract
The utility model discloses a multifunctional road drill bit. The road drill bit is composed of a connecting piece, a drill rod, a drill bit body, side drill bit bodies, stretchy arms, an oil cylinder and an oil cylinder push rod, wherein the drill rod penetrates through the oil cylinder, the oil cylinder push rod and the connecting piece in sequence, the oil cylinder push rod is fixedly connected with the connecting piece, the drill bit body is arranged at the top end of the drill rod, the two ends of the drill bit body are hinged to one ends of the two side drill bit bodies respectively, the other ends of the two side drill bit bodies are hinged to one ends of the two stretchy arms respectively, the other ends of the two stretchy arms are hinged to the connecting piece, the side drill bit bodies are provided with cement spraying ports, a cement spraying pipe penetrates through the drill rod, the drill bit body and the side drill bit bodies and is communicated with the cement spraying ports of the side drill bit bodies. The multifunctional road drill bit has the advantages of doing little damage to the roadbed and the road surface and being reliable in pile-forming quality.
Description
Technical field
The utility model relates to a kind of multifunctional road drill bit.
Background technology
Current highway drill bit, drilled hole is identical with the size of drill bit, if need the slightly larger of brill, may just destroy the roadbed on road surface, obviously the drill bit of this class is not suitable for highway boring.
Summary of the invention
The purpose of this utility model is to provide a kind of not only but also energy limit brill limit very little to roadbed pavement destruction to pour into slurry, the reliable a kind of multifunctional road drill bit of pile quality.
A kind of multifunctional road drill bit of the present utility model for achieving the above object, this highway drill bit is by connector, drilling rod, drill bit, sidetracking head, telescopic arm, oil cylinder, You Gang Tui Defend, spraying cement pipe forms, drilling rod runs through oil cylinder successively, You Gang Tui Defend and connector, between You Gang Tui Defend and connector for being fixedly connected with, drill bit is contained on the top of drilling rod, the two ends of drill bit are hinged with one end of two sidetracking heads respectively, the other end of two sidetracking heads is hinged with one end of two telescopic arms respectively, the other end and the connector of two telescopic arms are hinged, on sidetracking head, be provided with spraying cement mouth, spraying cement pipe runs through drilling rod, drill bit, sidetracking head is also connected with the spraying cement mouth of sidetracking head.
Further improvement of the present utility model: the top of drill bit is zigzag.
Another improvement of the present utility model: the top of sidetracking head is zigzag.
Because the utility model has adopted drill bit and sidetracking head, in the time of just can boring roadbed with the drill bit of small diameter, to increasing sidetracking head during soft base, just can get into larger hole, due to spraying cement pipe being installed on drill bit, just can the perfusion of brill limit, limit starch again, pile-forming effect is good.
Accompanying drawing explanation
Fig. 1 is that the structure of the concrete a kind of embodiment of the utility model is shown Yi figure;
Fig. 2 is that the drill bit of Fig. 1 launches schematic diagram.
Specific embodiments
As depicted in figs. 1 and 2, a kind of multifunctional road drill bit that the utility model is concrete, this highway drill bit is by connector 1, drilling rod 7, drill bit 3, sidetracking head 2, telescopic arm 8, oil cylinder 5, You Gang Tui Defend 6, spraying cement pipe 4 forms, drilling rod 7 runs through oil cylinder 5 successively, You Gang Tui Defend 6 and connector 1, between You Gang Tui Defend 6 and connector 1 for being fixedly connected with, drill bit 3 is contained on the top of drilling rod 7, the two ends of drill bit 3 are hinged with one end of two sidetracking heads 2 respectively, the other end of two sidetracking heads 2 is hinged with one end of two telescopic arms 8 respectively, the other end of two telescopic arms 8 and connector 1 are hinged, on sidetracking head 2, be provided with spraying cement mouth 9, spraying cement pipe 4 runs through drilling rod 7, drill bit 3, sidetracking head 2 is also connected with the spraying cement mouth 9 of sidetracking head 2, the top of drill bit 3 is zigzag, the top of drill bit 3 is zigzag, the top of sidetracking head 2 is zigzag.
