Description

A practical new geological exploration drill bit

technical field

The utility model relates to the technical field of geological exploration, in particular to a utility model geological exploration drill bit.

Background technique

Exploration drilling rigs are commonly used in petroleum geological exploration, and exploration drilling rigs are used in geological exploration, including coal fields, petroleum, metallurgy, minerals, geology, hydrology, non-ferrous metals, nuclear industry exploration and other fields. In my country, the Ministry of Geology, the Ministry of Metallurgy, the Ministry of Coal, and the Ministry of Nuclear Industry, etc., have controlled many machinery factories and other machinery factories, and now they have all undergone restructuring. Now the private geological drilling rig manufacturers are developing rapidly and emerging rapidly. Committed to the research and development of hydraulic fully automatic vehicle-mounted drilling rigs, all major prospecting plants have similar fully hydraulic vehicle-mounted drilling rigs.

At present, the main models of oil exploration drilling rigs are XY-5 and XY-6B. This drilling rig combines the advantages of vertical shaft hydraulic drilling rigs, and can perform small-diameter diamond drilling and large-diameter drilling. It can drill holes vertically. Slanted holes can also be drilled. The drilling rig has a large forward and backward moving distance, which is convenient for hole operation. The diameter of the through hole of the vertical shaft is large, which can meet the requirements of various drilling techniques. The weight of the whole machine is moderate, the disassembly performance is good, and it is convenient for transportation and relocation. This drilling rig is an ideal equipment for deep hole geological exploration drilling. But compared with the vehicle-mounted drilling rigs in the United States, Germany, and Italy, there is still a lot of room for development.

At present, there are many kinds of drill bits for geological exploration with excellent performance, but they have different degrees of low drilling efficiency, drill bits are prone to impact damage, rotation and slippage between the drill pipe and the sleeve, etc. In addition, it is generally necessary to drill first and then The reaming operation greatly affects the drilling efficiency and drilling accuracy.

Utility model content

In view of the above deficiencies, the purpose of this utility model is to provide a utility model geological exploration drill bit which can improve work efficiency, prevent the drill bit from being hit and damaged, and prevent the rotation between the drill pipe and the sleeve.

In order to achieve the above object, the utility model provides the following technical solutions: a utility model geological exploration drill bit, including a sleeve, a drill pipe and a drill bit, a drill pipe is movable in the sleeve, a drill bit is provided at the bottom of the drill pipe, and a drill pipe is provided at the bottom of the drill pipe. There is a fixed plate inside the sleeve, on which there are two guide rods respectively located on both sides of the drill rod, the upper ends of the drill rod and the guide rod both move through the guide plate, the guide plate is fixed on the inner upper part of the sleeve, and the guide rod The upper sleeve is provided with a compression spring located between the fixed plate and the guide plate, the two sides below the fixed plate are provided with limit blocks fixed in the sleeve, and the lower part of the drill pipe is fixed with a rounded table-shaped reaming bit located above the drill bit. The hole drill bit includes two symmetrically arranged drill bodies, the two drill bodies are fixed on the drill rod through bolt connection, and an arc-shaped cutting block is arranged on the outside of the drill body.

In a further optimized solution, a groove is provided inside the drill body, and a positioning block matching the groove is provided on the drill rod.

In a further optimized solution, the cutting block and the drill body are of an integral structure.

Compared with the prior art, the utility model has the beneficial effects that: the utility model has a simple structure, can ream the hole while drilling, and improve work efficiency, and the compressed spring can buffer the drill rod to prevent the drill bit from being hit and damaged. The guide rod limits the drill rod to prevent rotation between the drill rod and the sleeve.
