Mining plate-belt feeder

Abstract

The invention relates to an ore belt feeder, particularly a continuous feeder being sprocket driven, which comprises the drive sprocket on the drive shaft and the adhesive band end roller, chain mat fixed on the chain through screws, adhesive band arranged inside the chain mat, chain at both sides of the adhesive band, several carrying roller under the adhesive band with rolling bearing at both sides with the carrying roller supporting the chain mat through adhesive band, driving the continuous running of chains and chain mat through drive sprocket, realizing the goal of feeding material. The adhesive band head roller shares the same drive shaft with the drive sprocket, with the chain mat and adhesive band running at the same speed through chain driving. It is simple in structure, small in rolling friction, reduced in power consumption and running noise, with the chain mat being rigid with high impact feature.

Description

Technical field: [0001] The invention relates to a plate-belt feeder for mines, in particular to a continuous feeder supported by sprocket drive belts used in various mines above or below the mine, and is especially suitable for underground use in coal mines. Background technique: [0002] At present, the known mining feeders mainly include apron feeder, belt feeder, reciprocating (also known as K type) feeder, armor belt feeder, etc., the most commonly used in coal mines is reciprocating Feeder, in recent years, the amount of belt feeder is gradually increasing. The advantages of the apron feeder are good rigidity and impact resistance, but due to the existence of hard sliding friction during operation, the power loss is large and the noise is high. It is mainly used in metallurgical mines, and less used in coal mines. The belt feeder has stable transmission, high operating efficiency and low noise, but the carrying belt is a flexible body and cannot withstand impact, so t...

AI Technical Summary

Problems solved by technology

The advantages of the apron feeder are good rigidity and impact resistance, but due to the existence of hard sliding friction during operation, the power loss is large and the noise is high. It is mainly used in metallurgical mines and less used in coal mines.

The belt feeder has stable transmission, high operating efficiency, and low noise, but the carrying belt is a flexible body and cannot withstand impact, so the application occasions are greatly restricted

The reciprocating feeder is currently the most widely used feeding equipment in coal mines. It has a simple structure, reliable use, and a certain impact resistance. However, due to the existence of idle strokes, it cannot continuously feed materials, so the operating efficiency is low and the noise is large.

The transmission principle of the armor belt feeder is exactly the same as that of the belt feeder, except that a layer of armor is wrapped on the outside of the carrying tape, which improves the impact resistance, but because the armor is rigid, after the tape is loose, It is difficult to be tensioned again, so this kind of feeder often has the phenomenon that the tape slips on the driving roller, and the operation is not stable enough
