Automatic clay-mine cleaning device for ore carrying belt of heavy plate machine

Abstract

The invention discloses an automatic clay-mine cleaning device for an ore carrying belt of a heavy plate machine. The automatic clay-mine cleaning device comprises a lower supporting shaft, wherein the two ends of the lower supporting shaft are fixed through rolling bearings; the rolling bearings are matched with bearing bases; the bearing bases are fixedly arranged on a rack; the ore carrying belt is positioned above the lower supporting shaft without contact; connecting plates are arranged on the middle part of the lower supporting shaft; the four connecting plates are uniformly arranged inthe peripheral direction of the outer side of the lower supporting shaft; the two sides of each connecting plate are separately equipped with supporting rings which are in contact with the bottom of the ore carrying belt for supporting the ore carrying belt and the connecting plate; a row of steel wire brushes is arranged at the outer sides of the connecting plates, and the steel wire brushes arein contact with the ore carrying belt above; a row of flushing spray heads is arranged above the ore carrying belt; the spray heads are connected to a water supply pipeline; each supporting ring is formed by combining upper and lower semicircular rings, and can be embedded into the bottom slot of the ore carrying belt; and a fixing key for fixing each supporting ring and transmitting torque is arranged on the middle part of the corresponding supporting ring. The automatic clay-mine cleaning device can prolong service lives of upper and lower supporting rollers of the heavy plate machine, and reduces the faults that the upper and lower supporting rollers easily enter clay-mine.

Description

technical field [0001] The invention relates to an automatic mud ore cleaning device for an ore transport belt of a heavy plate machine, which belongs to the field of mine transport equipment. Background technique [0002] Ekou Iron Mine is the main raw material (iron ore powder) production base of Taiyuan Iron and Steel (Group) Co., Ltd. It is located in Daixian County, Shanxi Province, and belongs to the Taihang Mountains, an alpine mining area with an average altitude of 1,700 meters. The ore transportation volume is huge. Heavy plate machines are widely used in industrial sectors such as mines, building materials and coal. The heavy plate machine is mainly used under the silo and hopper with a certain silo pressure, to transport various large-capacity iron ore to various crushing and screening equipment evenly and continuously in a short distance, and it mainly transports coarse iron ore. [0003] The working principle and structural characteristics of the heavy plate ...

AI Technical Summary

Problems solved by technology

[0006] 1. In the process of use, the number of upper and lower supporting rollers of the heavy plate machine is large, there are many faults, the life is short, and it is easy to stick to mud ore, resulting in a large amount of cleaning, large vibration, heavy load, sticky ore on the ore transport belt, deviation, etc. technical challenge;

[0007] 2. The fatal shortcomings of the supporting rollers of the original heavy plate machine are: the bearings of the upper and lower supporting rollers are easy to enter the mud mine, there are many bearing failures, the bearing strength is insufficient, the bearing capacity is poor, the service life is short, the quantity is large, and the structure is complex
