Abstract
A soil sampler for a down-the-hole drill is a cylindrical cavity (1). One end of the cylindrical cavity (1) is provided with a hollow connector (1-1) which is matched with the down-the-hole drill and is connected with a male thread, and the other end of the cylindrical cavity (1) is provided with a soil sampling hole (1-2). The hollow connector (1-1) at one end of the cylindrical cavity (1) and the hole core of the soil sampling hole (1-2) are placed in the same axis, the circumferential face of the cylindrical cavity (1) is provided with a set of soil discharging grooves (1-3), and the distances and the groove positions of the adjacent soil discharging grooves (1-3) are both different. The soil sampler for the down-the-hole drill has the advantages that the soil sampler is changed to be arranged on the drill head portion of the down-the-hole drill, soil can be taken out, the degree of holing forming is high, and hole drilling efficiency is improved.
Description
Technical field
The utility model is specifically related to hidden hole drilling field, is specifically related to a kind of soil sampler for hidden hole drilling.
Background technology
At present, existing down-the-hold drill bit is all for punching at hard rock, and very painstaking while punching in particular surroundings, for example: run into internal layer soil property when softer, need to be at ground punching, and no matter down-the-hold drill bit is got to many deep-seateds, put, when down-the-hold drill bit takes out by the time, earth can again be trapped in again punch, drilling efficiency is lower, after pore-forming, hole wall is coarse, is easy to occur blocking phenomenon.
Utility model content
The purpose of this utility model is exactly is all for punching at hard rock for current existing down-the-hold drill bit, and very painstaking while punching in particular surroundings, for example: run into internal layer soil property when softer, need to be at ground punching, and no matter down-the-hold drill bit is got to many deep-seateds, put, when by the time down-the-hold drill bit takes out, earth can again be trapped in again punch, be difficult to pore-forming, and a kind of soil sampler for hidden hole drilling is provided.
The utility model is circular cylindrical cavity, there is supporting with the hidden hole drilling male thread hollow joint that connects circular cylindrical cavity one end, the other end has the hole of fetching earth, the hole heart in the hollow joint of circular cylindrical cavity one end and the hole of fetching earth is positioned on same axis, on circular cylindrical cavity periphery, have one group of casting groove, and the spacing of adjacent casting groove is all not identical with slotting position.
The end face in hole of fetching earth is provided with chamfering.
The utility model has the advantages that: soil sampler is changed the outfit in the bit head of down-the-hole drill, earth can be taken out, and drilling forming degree is higher, improve drilling efficiency, solve rock drilling earth problem.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Fig. 2 is Fig. 1 side sectional structure schematic diagram.
The specific embodiment
As shown in Figure 1, 2, the utility model is circular cylindrical cavity 1, there is supporting with the hidden hole drilling male thread hollow joint 1-1 that connects circular cylindrical cavity 1 one end, the other end has the hole 1-2 that fetches earth, the hole heart of the hollow joint 1-1 of circular cylindrical cavity 1 one end and the hole 1-2 that fetches earth is positioned on same axis, on circular cylindrical cavity 1 periphery, have one group of casting groove 1-3, and the spacing of adjacent casting groove 1-3 is all not identical with slotting position.
The end face of hole 1-2 of fetching earth is provided with chamfering.
Operating principle: when mixing this soil sampler while holing, in one group of casting groove 1-3, squeeze into respectively waste lubricating oil, further to improve perforating efficiency, in boring procedure, earth enters to the inner chamber of circular cylindrical cavity 1, when continuing boring downwards, thereby earth is constantly extruded and enters circular cylindrical cavity 1, soil sampler by rotation makes the hole inwall got more smooth, solid, reduce the mobility of earth, Deng punching during certain position, take out circular cylindrical cavity 1, then the hollow joint 1-1 place to circular cylindrical cavity 1 one end exerts pressure, earth in circular cylindrical cavity 1 inner chamber is discharged from one group of casting groove 1-3 on its periphery, so circulation.
Claims (2)
1. the soil sampler for hidden hole drilling, it is characterized in that it is circular cylindrical cavity (1), there is supporting with the hidden hole drilling male thread hollow joint (1-1) that connects circular cylindrical cavity (1) one end, the other end has the hole of fetching earth (1-2), the hollow joint (1-1) of circular cylindrical cavity (1) one end and the hole heart of the hole of fetching earth (1-2) are positioned on same axis, on circular cylindrical cavity (1) periphery, have one group of casting groove (1-3), and the spacing of adjacent casting groove (1-3) is all not identical with slotting position.
2. a kind of soil sampler for hidden hole drilling according to claim 1, the end face in the hole (1-2) that it is characterized in that fetching earth is provided with chamfering.
