Description

Apron feeder

Technical field

The utility model relates to a kind of mine equipment, particularly a kind of friction feeding device.

Background technology

Present known feeder mainly contains reciprocating type and the vibration-type feeder, the feeder of two kinds of feed-types, its structure and principle of work are: establish a deflector chute in the feed bin bottom, the deflector chute base plate is movable, drive the base plate iterative motion with an engine installation, when base plate when the material inlet direction is moved, material moves with base plate, finishes the feed process; When base plate during to reverse direction operation, material is under the combined action of internal pressure and inside and outside friction force, and material does not move with base plate; The continuous iterative motion of base plate, material constantly is sent to discharging opening in the storehouse.The difference of two kinds of feed-types is, feed frequency and amplitude different.

The shortcoming of reciprocating feeder is: the feeder base plate need bear the very big friction force of material in backhaul, so need bigger driving power, energy consumption is big; Because power is big, structure stress is also big, and weight of equipment is big; Because the feed process is a crank motion, the equipment vibrations are big, and noise is also big; Because structure stress is big, the movement parts quick abrasion, maintenance capacity is big; Because feed is discontinuous, capacity rating is lower.

The shortcoming of vibration-type feeder is: because feed frequency height, noise is also big; Owing to be that it is bigger that its amplitude and frequency are influenced by raw meal particle size and proportion by the high-frequency vibration feed, so the feeding coal instability, the adjustment of feeding coal is also relatively more difficult; Owing to be that feeder must starting of oscillation and is stabilized in certain frequency and amplitude by the vibrations feed, but it is very sensitive to the bottom slab stress state to shake parameter, so base plate can not bear bigger storehouse and press, need to increase the length of deflector chute under the storehouse, the result is the whole height that has increased feed bin, and construction investment is strengthened; Because the feed height strengthens, can't be used to replace a large amount of at present reciprocating feeders that use.

In sum, the feeder of two kinds of forms all can not be realized continuous-feeding, simultaneously in the working process, material and feeder trough all will produce relative motion, it is big all to have noise, and the big efficient of equipment energy consumption is low, easily produce dust in the quick abrasion, production process waves with serious pollution shortcoming.

The utility model content

The purpose of this utility model provides a kind of apron feeder, can overcome the defective of above-mentioned feeder, realizes continuous-feeding, and it is little to have running power simultaneously, and feeding coal is big, and is easy to adjust, and noise is little, the little characteristics of pollution in little, the working process of wear and tear.

The purpose of this utility model is to be achieved through the following technical solutions:

A kind of apron feeder, comprise feed well, casing, base, actuating device, driving drum, changed course cylinder, bearing and doffer, chain belt, described chain belt is combined by rubber face unitary-core flame-resistant conveying belt and first band, and bearing and doffer adopt damping spring to be installed on the base.

Adopt chain gear between described actuating device and the driving drum.

Described feed well side is equipped with handle hole.

Described driving drum, changed course cylinder are installed on the base by bearing seat, and bearing seat is provided with filler port.

Be the convenient feeding coal of regulating, described actuating device reductor adopts the scalable stepless reducer.

Be similarly the convenient feeding coal of regulating, described driving device motor adopts variable-frequency motor.

The beneficial effects of the utility model are, adopt the chain-belt type feed, can realize continuous-feeding, nothing relatively moves between feed process material and the chain belt, the friction that is produced is little, the operation power demand is little, by regulating reductor or variable-frequency motor rotating speed, the feeding coal of conveniently adjusted unit time, driving drum, changed course cylinder are installed on the base by bearing seat, bearing seat is provided with filler port, need not tear open under the situation of bearing cap shim and can refuel, and realizes the running of feeder long-time continuous; Between bearing and doffer and the base damping spring is installed, can reduces vibrations to greatest extent, reduce noise and parts are improved service life, in the working process, be difficult for producing dust and wave, can reduce pollution.
