Ore bin opening dredging device

Abstract

The invention discloses an ore bin opening dredging device. The device comprises a cross beam connected to the bottom of an ore bin, a water conveying pipe and a movable plate. A plurality of guide assemblies are connected with the bottom face of the cross beam in the length direction, a hydraulic cylinder is connected to the right end of the cross beam, the water conveying pipe is connected to the guide assemblies in a left-right sliding mode, a right port of the water conveying pipe communicates with a rotary connector, the other end of the rotary connector communicates with a water inlet pipe, the water inlet pipe communicates with a high-pressure pump, a piston rod of the hydraulic cylinder is connected with the outer side of the rotary connector, the left end of the water conveying pipe is in threaded connection with a water gun, and an ejector head is arranged on the left side of the water gun. The movable plate is detachably connected to the circumferential wall of a discharge hopper of the ore bin. An ejector pipe is arranged on the right side face of the movable plate. When the ejector head abuts against the ejector pipe, the movable plate seals a window in the circumferential wall of the discharge hopper. The structure is simple, operation is convenient and fast, blockage of ore to a bin opening can be effectively dredged, the labor intensity is lowered, the working efficiency is improved, and personal health is ensured.

Description

technical field [0001] The invention belongs to the field of material storage, and in particular relates to a dredging device for a mine storehouse. Background technique [0002] In mining, large-scale silos are usually used to store mineral materials for transshipment. In the actual production process, the problem of blockage at the silo is often unavoidable. If it cannot be unblocked in time, it will have a greater impact on production. Generally, large-scale There is no automatic dredging device when the silo is built. In order to solve the dredging problem, the operator generally relies on the operator to enter the material port from the belt road, and then washes the arched mineral material upward with a water gun. Using this dredging method, the water gun The scouring angle and position are not easy to control, and the operation time is long, the work efficiency is low, and the labor intensity is high. What is more serious is that due to the scouring, the arched minera...

[0002] In mining, large-scale silos are usually used to store mineral materials for transshipment. In the actual production process, the problem of blockage at the silo is often unavoidable. If it cannot be unblocked in time, it will have a greater impact on production. Generally, large-scale There is no automatic dredging device when the silo is built. In order to solve the dredging problem, the operator generally relies on the operator to enter the material port from the belt road, and then washes the arched mineral material upward with a water gun. Using this dredging method, the water gun The scouring angle and position are not easy to control, and the operation time is long, the work efficiency is low, and the labor intensity is high. What is more serious is that due to the scouring, the arched mineral material sometimes collapses suddenly, which poses a serious threat to the personal safety of the operators.
