Hydraulic manual drill

Abstract

A hydraulic manual drill comprises a drill bit rod, the lower end of the drill bit rod is of a threaded structure, the upper end of the drill bit rod is of a polished rod structure, a lower box body is arranged on the outer side of the threaded structure segment of the drill bit rod, the threaded structure segment stretches out of the lower box body, an upper box body is arranged on the outer side of the polished rod structure segment of the drill bit rod, the upper box body is sealed with a bottom cover through an upper box body top cover, a turbine blade is arranged on the polished rod structure segment, the inner side of the upper box body can move relative to the inner side of the lower box body through a roller, a supporting leg is arranged on the outer side of the lower box body, a pedal is arranged on the supporting leg, a hydraulic system is connected to the pedal, a supporting piston mechanism is arranged in the lower box body, and the upper box body bottom cover is supported by the upper end of the supporting piston mechanism. The hydraulic manual drill is small in size, field carrying is facilitated, no electricity is required, limitation of the field operation condition is reduced, the hydraulic manual drill can be operated by one person, fitted personnel required by outdoor work is reduced, cost is reduced, the operation height can be adjusted according the height of an operator, and the hydraulic manual drill is simple and convenient to use.

Description

technical field [0001] The invention relates to a hydraulic manual drill. Background technique [0002] The existing blasting or pre-splitting machines for mountains and rocks are quite bulky or need to work under the condition of electricity, and the blasting or pre-splitting of mountains and rocks is often carried out in poor and difficult places such as mountainous areas and fields. Such equipment will inevitably appear cumbersome or cannot be used due to conditional restrictions, and it will not only consume too much manpower if it is fully operated manually. All a drilling machine that saves time and effort and is less restricted by field conditions becomes a necessity for blasting or pre-splitting work. Contents of the invention [0003] The purpose of the present invention is to provide a hydraulic manual drill, which is small in size and convenient to carry in the field; the instrument does not need electricity, which reduces the limitations of field operating con...
