Description

Crawler chain type feeder

Technical field

The utility model relates to a kind of mine material and other warehousing department's door feed bin feeder, especially a kind of crawler chain type feeder.

Background technology

The feeder that at present known above-mentioned occasion is used has: K type reciprocating feeder, vibrating feeder, adhesive tape type feeder, first apron feeder, mining plate-belt feeder, the feeder of several feed-types such as chain belt type feeding machine, its structure and principle of work be respectively: in feed bin bottom, one deflector chute is set, deflector chute base plate is movable, K type reciprocating feeder drives base plate to do iterative motion with a kind of engine installation, vibrating feeder drives base plate to do double vibrations with a kind of engine installation, when base plate moves to material inlet, material moves with base plate, complete the first half process of feed, when base plate is during to material inlet reverse motions, material is under the combined action of storehouse pressure and friction force, the later half process capability of feed declines, the continuous iterative motion of base plate or vibration, in storehouse, material is constantly sent material mouthful, what wherein play a major role is the frequency of feed and the difference of amplitude.Adhesive tape type feeder, its structure of first apron feeder and principle of work be respectively: in feed bin bottom, one deflector chute is set, deflector chute base plate is adhesive tape or first band, by the friction producing between cylinder and adhesive tape, make adhesive tape, first band do annular circulating motion, drive material to the motion of discharging opening direction, the key distinction is the anti-material impact ability of adhesive tape and first band.

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

Oscillating feeder: because feed relies on vibration, cause noise large, join 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 larger, 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 bear larger storehouse while pressing at base plate, affect the feed ability of feeder and the intensity of feeder.

Adhesive tape type feeder, first apron feeder: due to the unbalance loading of material in feed process, it is improper that stretching device is adjusted, and easily causes the sideslip of adhesive tape and first band, and impact is produced; Adhesive tape type feeder is torn damage etc. due to what larger material and foreign matter easily caused adhesive tape.

Mining plate-belt feeder: adopt plate chain type transmission, carrier bar is fastened on chain by bolt, disposed inboard adhesive tape, by sprocket wheel tensioning end to end, and chain drive-belt is realized plate chain and is done annular circulating motion.The plate-chain mechanism size of mining plate-belt feeder is large, and requiring has enough rigidity, and plate chain weight is relatively large; Because mining plate-belt feeder is done annular circulating motion, carrier bar is with bolts, at linear portion and segment of curve operation, can produce the relative displacement between carrier bar and carrier bar, carries thin material in the easy material folding of segment of curve, there will be backhaul for material phenomenon.

Chain belt type feeding machine: the combination chain that adopts first sheet, roller chain, bearing pin serial connection to form, under the driving of head roll sprocket wheel, carries out the conveying of material; When combination chain bearing pin is installed, first sheet is installed on bearing pin middle part, and roller chain only can be arranged on the two ends of bearing pin, roller chain and first sheet unbalance stress during work, and when the company of combination is wide, bearing pin is flexible.
