Description

Technical Field

[0001] The utility model relates to the field of reamer, in particular to a reamer capable of replacing cutting and expanding teeth. Background Art

[0002] The reamer is a commonly used tool in exploration work. The main function of the reamer is to expand the hole after drilling, because the diameter of the hole drilled is smaller than the diameter of the hole required for exploration, so the use of the reamer is very important.

[0003] Chinese patent authorization application number: CN202020322096.4 provides a hole reamer for geological drilling. Since the opening is narrow on the outside and wide on the inside, the scheme can effectively prevent the iron drill in the opening from falling out. Since the inner wall of the iron drill is flush with the inner wall of the steel bucket, the cone block embedded in the steel bucket can clamp the iron drill, effectively preventing the iron drill from moving in the opening. The cone block and the baffle are fixed together by a screw and a fixing ring. The baffle is firmly fixed on the hole reamer through a fixing sleeve, thereby effectively preventing the cone block from shaking in the steel bucket. The spring in the groove is in a compressed state, exerting a downward elastic force on the cone block, so that the cone block fits tightly with the steel bucket, further enhancing the stability of the iron drill in the opening.

[0004] Existing reamers have certain drawbacks when in use. First, most of the reamers are fixed structures, and the cutting and expanding teeth on the surface of the reamers are severely worn after long-term use. However, the cutting and expanding teeth of the overall structure cannot be easily replaced and disassembled, and the cutting and expanding teeth need to be replaced as a whole, which increases the cost of using the cutting and expanding teeth. For this reason, we propose a reamer with replaceable cutting and expanding teeth. Utility Model Content
