Description
Technical Field
The utility model relates to a drill bit equipment technical field specifically is a major diameter rock core drill bit.
Background
The core drill is one kind of core drilling equipment, and is mainly used for general survey and exploration of metal and nonmetal solid minerals, and in addition, can also be used for engineering geological survey, hydrogeological survey, general survey and exploration of oil and gas fields, well drilling and the like. Because the core drilling machine needs to take out relatively complete stratum rock samples without mixing and non-deflection, the core drilling machines are all rotary drilling machines, the size of a drill bit serving as a core component of the core drilling machine is large, the diameter of a cylinder of some drill bits is larger than four meters, the circular cylinder is inconvenient to transport, and the drill bit cannot pass through part of height-limited road sections.
SUMMERY OF THE UTILITY MODEL
In order to solve the defects of the prior art, the utility model provides a large-diameter core drill bit solves the problem of proposing in the background art.
In order to achieve the above object, the utility model provides a following technical scheme: a large-diameter rock core drill bit comprises a cylinder body and an upper cover plate, wherein the upper cover plate is arranged on the inner wall of the cylinder body, the upper part of the upper cover plate is connected with the upper cover plate, the upper part of the upper cover plate is connected with two rib plates, the two rib plates are arranged in a crossed mode, the upper part of the upper cover plate is provided with a square head box, the square head box is arranged at the crossed position of the two rib plates, the lower part of the cylinder body is connected with a cutting ring, the lower part of the cutting ring is provided with a pick seat, picks are arranged in the pick seat, the cylinder body is a long circular cylinder, and the lower parts of two straight edges of the cylinder body are provided with square grooves;
furthermore, at least two fillets are connected to the arc part of the side wall of the cylinder body;
furthermore, at least two cutting picks are arranged at equal intervals, the cutting tip of one cutting pick points into the cylinder, and the cutting tip of the other cutting pick points out of the cylinder;
furthermore, the cutting ring is welded on the lower part of the cylinder body, and the cutting teeth are fixed on the cutting tooth seat through the elastic ring.
The utility model adopts the above structure to gain beneficial effect as follows: the utility model provides a large-diameter core drill, in the transportation of the large-diameter core drill, the barrel is put on a transport vehicle, and is assisted by a fixed rope, so that the barrel is fixed on the transport vehicle, the transportation is safer, the transportation height is reduced by the way, and the transportation efficiency is increased by passing through a part of height-limited road section; the cutting teeth are disassembled and replaced through the special disassembling tool, so that the drill bit can be used for different kinds of rock and soil, and later maintenance is facilitated.
