Description

A kind of Rock and Soil Drilling machine bit

Technical field

Geotechnical Engineering field is the utility model is related to, more particularly to a kind of Rock and Soil Drilling machine bit.

Background technology

Existing rock drilling rig drill bit structure is single, is all the pattern fed in rotation, feed speed is slow, runs into hard rock Layer can have that brill is motionless.

The content of the invention

Goal of the invention：In order to overcome the deficiencies in the prior art, the utility model provides a kind of with impulsive force Rock and Soil Drilling machine bit.

Technical scheme：To achieve the above object, Rock and Soil Drilling machine bit of the present utility model, including rotating cylinder and slide cartridge, The slide cartridge is set in the outside of the rotating cylinder lower end, and the lower circumferential array of the rotating cylinder is provided with a circle main blade, adjacent Percussive tool bit is provided between two main blades, all percussive tool bits are installed on the slide cartridge；The rotating cylinder can be along perpendicular Straight axis of rotation, the slide cartridge move up and down with the axial rule while rotating cylinder synchronous axial system along rotating cylinder；When the punching When hitting cutter head and being in extreme lower position, the point of a knife of percussive tool bit is less than the point of a knife of the main blade, when the percussive tool bit is in most During high position, the point of a knife of percussive tool bit is not less than the point of a knife of the main blade.

Further, in addition to the fixed cylinder that is sheathed on the outside of the rotating cylinder；It is provided between the slide cartridge and the rotating cylinder Flexible member, the flexible member make the slide cartridge have the movement tendency moved upwards relative to the rotating cylinder；The fixed cylinder Lower end be provided with the actuator for making the slide cartridge move up and down.

Further, the actuator is edge cam, and the upper end of the slide cartridge, which is provided with, coordinates the actuator to use Counterface.

Further, the flexible member is stage clip.

Further, the actuator include from first height gradually angled transition to the second height slant transition surface with And the step transition face of the first height is stepped to from the second height；The counterface includes the contact surface of crest shape.

Beneficial effect：Brill machine bit of the present utility model includes main blade and impact blade, and main blade is used to drill, rushed Hit blade to be used to impact stratum in boring procedure, destroy hard rock stratum, main blade is smoothly fed, improve penetration rate.

Brief description of the drawings

Accompanying drawing 1 is the structure chart of Rock and Soil Drilling machine bit；

Accompanying drawing 2 is the sectional view of Rock and Soil Drilling machine bit.

Embodiment

The utility model is further described below in conjunction with the accompanying drawings.

Rock and Soil Drilling machine bit as shown in accompanying drawing 1 and accompanying drawing 2, including rotating cylinder 1 and slide cartridge 2, the slide cartridge 2 are set in The outside of the lower end of rotating cylinder 1, the lower circumferential array of the rotating cylinder 1 are provided with a circle main blade 3, two neighboring main blade 3 Between be provided with percussive tool bit 4, all percussive tool bits 4 are installed on the slide cartridge 2；The rotating cylinder 1 can be along vertical rotating shaft Rotate, the slide cartridge moves up and down with axial rule while 1 synchronous axial system of rotating cylinder along rotating cylinder 1；When the impact knives First 4 when being in extreme lower position, and the point of a knife of percussive tool bit 4 is less than the point of a knife of the main blade 3, when the percussive tool bit 4 is in most During high position, the point of a knife of percussive tool bit 4 is not less than the point of a knife of the main blade 3.

Also include the fixed cylinder 5 for being sheathed on the outside of rotating cylinder 1；Elasticity member is provided between the slide cartridge 2 and the rotating cylinder 1 Part 6, the flexible member 6 make the slide cartridge 2 have the movement tendency moved upwards relative to the rotating cylinder 1；The fixed cylinder 5 Lower end is provided with the actuator 7 for making the slide cartridge 2 move up and down.
