Description

First chain feeder

Technical field

The utility model relates to a kind of first chain feeder, is particularly useful for the feed bin feeder of mine material and other warehousing department's door.

Background technology

The feeder of current use has: the feeder of several feed-types such as K type reciprocating feeder, vibrating feeder, apron feeder, first apron feeder.

The base plate of K type reciprocating feeder is in crank motion, and need bear material larger friction force during backhaul, transmission device need provide larger driving power, and energy ezpenditure is large; Because the power of mechanism is large, mechanism's feeding process moves reciprocatingly again simultaneously, causes the impact that vibration equipment is large, noise large, moving member is subject to also large, under being in this strained condition, and moving member quick abrasion, maintenance capacity is large; And due to feed discontinuous, capacity rating is lower.

Oscillating feeder relies on vibration due to feed, causes noise large, joins the parts rapid wear that shakes.Owing to being by high-frequency vibration feed, its amplitude and frequency are subject to raw meal particle size and proportion impact is comparatively large, so feeding coal is unstable, the adjustment of feeding coal is more difficult.And due to vibrating feed, feeder must have stable frequency and amplitude in vibrating feed process, but vibration parameters is very sensitive to bottom slab stress state, therefore when base plate bears larger storehouse pressure, affects the feed ability of feeder and the intensity of feeder.

Apron feeder mainly by producing friction between head roll and adhesive tape, makes adhesive tape do annular circulating motion, drives material to move to discharging opening direction.The tensioning in feeding process of adhesive tape type feeder not at that time, easily causes rubber belt from deviating, forms unbalance loading, and impact is produced, and when having larger material and foreign matter, that easily causes adhesive tape tears damage.

The transmission principle of first apron feeder is identical with adhesive tape type feeder; just wrap up in the outside of carrying adhesive tape-layer protection first; shock proof ability is improved with this; but because protection first is rigidity; therefore, after the adhesive tape of inner side is lax, be just difficult to be tensioned again, long-pending when having material and water between first band and adhesive tape; easy generation skidding, cannot realize transmission.
