Machine head and machine tail centralized lubricating system of belt conveyor

Abstract

The invention discloses a machine head and machine tail centralized lubricating system of a belt conveyor, comprising a main oil supply pipeline, a lubricant pump, a one-way valve, a plurality of oil supply branches, a plurality of oil feed distributors, an oil return pipeline and an overflow valve, wherein the lubricant pump continuously injects lubricating grease inside an oil storage tank into the main oil supply pipeline; the one-way valve is arranged on the main oil supply pipeline; the plurality of oil supply branches are respectively connected with an oil outlet of the main oil supply pipeline; the plurality of oil feed distributors are respectively arranged on the plurality of oil supply branches; the oil return pipeline is communicated with the main oil supply pipeline; the overflow valve is arranged on the oil return pipeline; an oil inlet of the main oil supply pipeline is connected with an oil injection orifice of the lubricant pump; the oil outlets of the plurality of oil supply branches are connected with the lubricating positions of the machine head and the machine tail of the belt conveyor, wherein the lubricating positions need to be lubricated; and the oil outlet of the oil return pipeline is connected into the oil storage tank. The invention has the advantages of reasonable design, easy operation, safe and reliable work and good lubricating effect, can also realize the centralized lubrication of a plurality of lubricating points and effectively overcomes the defects and the shortages of nonuniform and discontinuous lubrication, poor lubricating reliability, low lubricating efficiency, and the like of the traditional lubrication mode.

Description

technical field [0001] The invention relates to an oil lubricating system, in particular to a centralized lubricating system for the head and tail of a belt conveyor. Background technique [0002] Nowadays, when lubricating the parts that need to be lubricated at the head and tail of the belt conveyor used in coal mines, most of them use distributed lubrication or manual lubrication. However, in the actual use process, the above two lubrication methods have various defects and shortcomings such as complicated operation, intermittent lubrication, high labor intensity, and low efficiency, and cannot meet the requirements of the lubricating grease required for the head and tail of the belt conveyor. The actual requirements of injection volume and injection frequency, so the reliability is not high.
