Abstract
The utility model discloses a rotary drum-blade integral reclaiming drill bit which comprises a connecting shaft and a rotary drum, wherein the rotary drum is positioned outside the connecting shaft, tunneling blades are connected between the rotary drum and the connecting shaft, the front end of the rotary drum is connected with alloy cutter teeth, and the front end of the connecting shaft is connected with crushing cutter teeth. A spiral drill tunnels, winds and hoists materials along with the rotary drum-blade integral reclaiming drill bit, and the materials are piled up to enter spirals blades of the spiral drill. The crushing range is large, and the crushing capacity is strong, so that sampling also can be conducted even though blocky materials and materials with hardened or frozen surface layers exist. The rotary drum-blade integral reclaiming drill bit is applicable to spiral drills conducting sampling for bulk materials.
Description
Technical field
The utility model relates to a kind of drill bit that is used for the spiral drill of bulk material sampling.
Background technology
At present, the spiral drill structural shape that is used for the bulk material sampling on the market mainly is made up of main shaft, helical blade, cylindrical shell, actuating unit, drill bit etc., and wherein with main axis rotation, drill bit is installed in the front-end of spindle broken material to helical blade in the barrel inboard; Be used for the spiral take out device mechanism of bulk material now, breaking capacity is poor, runs into to harden in the top layer and during block material, and barrel does not have the execution action of cutting and crushing with respect to material, occurs easily getting stuck and gets phenomenon less than material; Particularly run into the weather temperature than the occasion at the end, phenomenon appears freezing in material, and the broken scope of drill bit is little, and the spiral drill cylindrical shell Buddhist nun that is obstructed on the material surface is skidded, and can't normally sample to material.
Summary of the invention
The purpose of this utility model is to provide the strong blade integral type of revolving of a kind of breaking capacity to get the material drill bit.
The purpose of this utility model is achieved in that this drill bit comprises coupling shaft and revolve tube, revolves tube and is positioned at the coupling shaft outside, revolves between tube and the coupling shaft to be connected with the driving blade, revolves that a front end is connected with the alloy cutter tooth, the coupling shaft front end is connected with broken cutter tooth.
Drill bit revolves tube and equates with spiral drill cylindrical shell external diameter or be a bit larger tham the spiral drill cylindrical shell, revolves that tube rotates, fragmentation, loosens, tunnels material, and top association spiral drill cylindrical shell descends with it; Revolve between tube and the coupling shaft and be connected or be cast into one drill bit is revolved an interior material fragmentation, loosens and get material with one or more groups driving blade; The coupling shaft front end is inlayed one or more groups broken cutter tooth, in order to driving axle head material.
During spiral take out device overall operation, revolve a blade integral type and get the material drill bit with spiral drill helical blade main axis rotation, and the driving that descends, revolving a blade integral type gets the material drill bit and material is carried out fragmentation or loosens, tunnels and drop in the material, material can be got the rotation of material drill bit along with revolving a blade integral type, elevator fragmentation, the bulk material after loosening enter in the upper level spiral drill helical blade to the drill bit upper end, realize the sampling of material and upwards promote.
A blade integral type is got material drill bit driving to spiral drill and elevator promotes material with revolving, and piles up material and rises and enter the spiral drill helical blade, and broken scope is big, and breaking capacity is strong, even have lump material, top layer to harden or freeze material and can sample equally.
Below in conjunction with accompanying drawing the utility model is described in further detail:
