Abstract

The invention relates to the field of geological exploration, in particular to a hole enlarger for geological exploration. The hole enlarger for geological exploration comprises an expanding mechanism, an opening mechanism, an opening and closing mechanism, a rotating mechanism and a limiting mechanism. The bottom of a cover plate is hinged with two symmetrical expanding plates through a hinge, and when a punched hole is expanded, a hammer is used to downwardly hammer a pressure bar to realize downward movement of a pressure plate, the two expanding plates move oppositely, and the purpose of expanding a rear hole is finally achieved. The expanding mechanism is matched with the limiting mechanism, in the case of expanding, a clamping tooth and a limiting tooth are clamped to avoid soil collapse near the hole caused by reset of the pressure rod, a connecting rod is in sliding connection in the pressure rod, a handle is rotated to realize rotation of the connecting rod in the pressure rod, a connecting block at the top of a bit is further clamped inside a fixing block, the bit is fixed, a fixed nut is then fixed at the top of the pressure rod to limit the connecting rod, and slippingof the bit in the case of hole punching can be avoided.

Description

technical field [0001] The invention relates to the field of geological exploration, in particular to a hole reamer for geological exploration. Background technique [0002] "Geological prospecting" refers to investigation and research activities in which geological exploration and detection are carried out through various means and methods, a suitable bearing layer is determined, and the foundation type is determined according to the foundation bearing capacity of the bearing layer, and foundation parameters are calculated. It is the discovery of mineral deposits with industrial significance in the general survey of mineral resources. In order to ascertain the quality and quantity of mineral products, as well as the technical conditions for mining and utilization, provide mineral reserves and geological data required for mine construction design, and analyze rocks and strata in a certain area. Conduct investigation and research work on geological conditions such as geology,...
