Horizontal drilling tool without damaging permeability of tailing sand

Abstract

The invention discloses a horizontal drilling tool without damaging permeability of tailing sand. The horizontal drilling tool comprises a drilling tool assembly, a connector and fixing parts, wherein the drilling tool assembly is used for cutting soil and comprises a drill handle and a drill bit, the drill bit is fixedly connected to one end of the drill handle, and a fixing opening is formed in the drill handle; the connector is used for connecting the drilling tool assembly with a machine body, and a mounting groove matched with the drill handle to be inserted is formed in the end, away from the machine body, of the connector; and the fixing parts are used for fixing the drill handle in the mounting groove, and the fixing parts are symmetrically arranged on the side wall of the connector. According to the horizontal drilling tool, a drill rod is slidably connected into the mounting groove formed in the end of the connector and fixed through the fixing parts, so that the drill handle cannot be separated from the mounting groove; and the locking effect of a locking part can be quickly relieved through an unlocking part, so that a user can take out the drill handle from the mounting groove for replacement, and the user can replace the drilling tool assembly very conveniently.

Description

technical field [0001] The invention relates to the technical field of horizontal drilling tools, in particular to a horizontal drilling tool that does not damage the permeability of tailings sand. Background technique [0002] Most of the tailings sand after grinding and smelting of mines and non-metallic mines are discharged to the tailings pond for centralized storage; the tailings pond is one of the major hazards of mining enterprises, and the dam body of the tailings pond is discharged Seepage to reduce the dam seepage line is a common means to control the safety hazards of tailings ponds. [0003] When draining the tailings dam body, it is often necessary to use a horizontal drilling tool that does not damage the permeability of the tailings sand to drill holes to install the seepage pipe, and then the existing horizontal drilling tool that does not damage the permeability of the tailings sand Tool components and connectors are usually fixed together by bolts and scre...

AI Technical Summary

Problems solved by technology

[0003] When draining the tailings dam body, it is often necessary to use a horizontal drilling tool that does not damage the permeability of the tailings sand to drill holes to install the seepage pipe, and then the existing horizontal drilling tool that does not damage the permeability of the tailings sand Tool components and connectors are usually fixed together by bolts and screws, so when the drill bit needs to be replaced after long-term use, due to the long-term contact and friction between the drill tool and the tailings, the ends of the bolts and screws are severely worn, which in turn makes it difficult to disassemble. It affects the efficiency of the user to disassemble and replace the drill bit, which in turn brings inconvenience to the user
