Abstract
The utility model relates to a reducing sampling drill bit with the functions of cracking and division, belonging to a sampling drill bit. The drill bit is provided with a reducing barrel in which a conical drill bit is arranged, the front part of the conical drill bit is provided with cracking cutter teeth, and material dividing holes are arranged on the reducing barrel; and the reducing barrel is provided with an upper barrel and a lower barrel, the diameter of the lower barrel is greater than that of the upper barrel, a conical transition barrel is arranged between the upper barrel and the lower barrel, a reversed thread-shaped cracking rib is arranged on the inner wall of the conical transition barrel, and the material dividing holes are positioned on the upper barrel. The sampling drill bit has the advantage of simple structure; a spiral drill rotates along with a main shaft, the conical drill bit is driven to drop for sampling materials, the materials rise along with a spiral blade, massive materials are continuously extruded and pulverized by the friction force of the conical drill bit and the inner wall of the spiral barrel, thereby the sampling drill bit realizes the function of cracking and can sample the massive materials; and as the sampling amount is increased after an external barrel body is reduced, and the upper end of the reducing barrel is provided with the dividing holes, the sampling drill bit carries out primary division to the material so that the representativeness of samples is greatly increased.
Description
Technical field
The utility model relates to a kind of chisel bit, and particularly a kind of have a broken division function reducing chisel bit of holding concurrently.
Background technology
At present, the spiral drill structural shape that is used for the 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; The spiral take out device mechanism that is used for material now, the broken scope of drill bit is little, spiral tube diameter is subjected to the sampling restriction, it is too big that diameter is unfit to do, and screw spindle and inner core arm gap are little, only can sample the lump material of screw spindle and inner tube wall interstice coverage, breaking capacity is poor, occur easily getting stuck and get phenomenon for bulk materials, do not have fragmentation and division function, thereby institute's its representativeness of sample thief is relatively poor less than material.
The utility model content
The purpose of this utility model is to provide a kind of: can carry out the broken broken division function reducing chisel bit of holding concurrently of having of division that can also carry out simultaneously to sample.
The purpose of this utility model is achieved in that this drill bit has reducing cylinder, and taper bit is arranged in reducing cylinder, in the front portion of taper bit broken cutter tooth is arranged, and material division hole is arranged on reducing cylinder.
Described reducing cylinder has top cylinder and doffing, and the diameter of doffing has the tapering transition tube greater than the diameter of top cylinder between top cylinder and doffing, and the broken muscle of reverse thread shape is arranged on tapering transition tube inwall, and material division hole is positioned on the top cylinder.
Described taper bit has the taper auger spindle, on the taper auger spindle, helical blade is arranged, there is coupling shaft upper end at the taper auger spindle, adapt with the internal diameter of top cylinder and the internal diameter of doffing respectively at helical blade that is positioned at top cylinder and the helical blade that is positioned at doffing, on the helical blade of doffing and tapering transition tube position, broken cutter tooth is arranged.
Beneficial effect, owing to adopted such scheme, the drill bit rotation is carried out fragmentation to material, and outside cylindrical shell enters material inside, and the inner barrel material rotates with blade, and material moves up, and enters the top helical blade; When running into bulk materials, along with moving on the material, the broken muscle of reverse thread that taper bit drives on bulk materials and the tapering transition tube inwall constantly pushes, pulverizes, material can be entered in the upper level helical blade, realize the sampling of bulk materials and upwards lifting, because its sampling quantity of outside cylindrical shell enlarged diameter increases,, material is carried out a division so externally the cylindrical shell upper end offers the division hole.Can carry out fragmentation to sample and can also carry out division simultaneously, reach the purpose of this utility model.
Advantage: this chisel bit is simple in structure, spiral drill is with main axis rotation, driving taper bit decline takes a sample to material, material rises with helical blade, bulk materials is subjected to friction force constantly to push, pulverize lump material at taper bit and spiral tube inwall, realize broken function, enter in the upper level helical blade, realize sampling relatively large shape material; Behind outside cylindrical shell reducing, sampling quantity increases, and in reducing cylindrical shell upper end the division hole is arranged, and material is carried out a division, thereby improve the representativeness of sample greatly.
