Abstract
The utility model discloses an inner concave four-wing drill bit of a petroleum and geological mining exploration drilling rig. A drill bit body takes the shape of a spiral cylinder, a connector body is arranged at the tail part of the drill bit body, four drilling wings are arranged at the head part of the drill bit body at an equal distance and are inclined outward the central axis of the drill bit body, and each drilling wing comprises a cambered outer back and a plane inner back. Through the arrangement of the four drilling wings, the stability of the drill bit during working is guaranteed, the cambered working side surface guarantees the effective discharge of slag, and the drill bit is not easy to wear during use.
Description
Technical field
The utility model relates to a kind of oil mine prospection drill rig components, is specifically related to a kind of indent four wing bit of oil mine prospection rig.
Background technology
At present, the rig that is used for the oil mine prospection generally uses the scraper type drill bit, mainly relies on the shearing broken rock, exists bit wear fast, defectives such as drilling efficiency deficiency.When particularly creeping in the hag alternating layers, drag bit very easily weares and teares, and causes drilling time long.
The utility model content
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, and a kind of indent four wing bit of oil mine prospection rig is provided.
The indent four wing bit of a kind of oil mine prospection rig that the utility model provides comprises drill body, this drill body is the spiral circle cylindricality, afterbody at drill body is provided with fittings body, this bit body head equidistantly is provided with four brill wings of inclining to described drill body central axis outward, and the described brill wing comprises the back of the body in the outer back of the body of cabochon and the plane.
The utility model passes through four settings of boring the wings, the stability when having guaranteed its work, and the work side of cambered surface has guaranteed effective discharge of slag charge, makes drill bit not easy to wear in use.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Below in conjunction with specific embodiment, the utility model is described further.Should be understood that following examples only are used to the utility model is described but not are used to limit scope of the present utility model.
Referring to Fig. 1, the indent four wing bit of a kind of oil mine prospection rig that the utility model provides comprises drill body 1, this drill body 1 is the spiral circle cylindricality, afterbody at drill body 1 is provided with fittings body 2, this bit body head equidistantly is provided with four brill wings 3 of inclining to described drill body central axis outward, and the described brill wing 3 comprises that cabochon carries on the back back of the body 3b in 3a and the plane outward.
Claims (1)
