Description

A kind of link-belt feeder

Technical field

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

Background technology

The feeder that uses has at present: the feeder of several feed-types such as K type reciprocating feeder, vibrating feeder, apron feeder, First Tape Feeder, mining plate-belt feeder.

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

Oscillating feeder: because feed relies on vibration, cause noise big, join the parts rapid wear that shakes.Owing to be by the high-frequency vibration feed, its amplitude and frequency are subjected to raw meal particle size and the proportion influence is bigger, so the feeding coal instability, the adjustment of feeding coal is difficulty relatively.And because vibrating feed, feeder must have stable frequency and amplitude in the vibrating feed process, but vibration parameters is very sensitive to the bottom slab stress state, so when base plate bears bigger storehouse pressure, influence the feed ability of feeder and the intensity of feeder.

Number of patent application is 200620080321.8 disclosed a kind of apron feeders, mainly is by producing friction between head roll and the adhesive tape, make adhesive tape do annular circulating motion, driving material and move to the discharging opening direction.The stretching device adjustment in the feed process of adhesive tape type feeder easily causes rubber belt from deviating not at that time, forms unbalance loading, and influence is produced, and when bigger material and foreign matter, easily causes the damage of tearing of adhesive tape.

The patent No. is ZL 99201790.4 disclosed a kind of First Tape Feeders, its transmission principle and apron feeder are identical, just wrapped up one deck armor in the outside of carrying adhesive tape, improve shock proof ability with this, but because armor is a rigidity, therefore after the adhesive tape under it is lax, just be difficult to be tensioned again, or when between first band and the adhesive tape water or coal slime being arranged, all easily produce skidding, can't realize normal transmission.

The patent No. is ZL 200720018356.3 disclosed mining plate-belt feeders, adopting the plate chain type transmission, is to have wrapped up one deck carrier bar in the outside of carrying adhesive tape, and carrier bar is by being bolted on the chain, by sprocket wheel tensioning end to end, and chain drive-belt realization plate chain is done annular circulating motion.Because mining plate-belt feeder is done annular circulating motion, carrier bar adopts bolted connection, and the relative displacement between linear portion and segment of curve operation meeting generation carrier bar and carrier bar carries thin material in the easy material folding of segment of curve, backhaul band material phenomenon occurs.The plate-chain mechanism size of this feeder is bigger in addition, and requiring has enough rigidity, so plate chain weight is relatively large.

The utility model content

The purpose of this utility model is the weak point at prior art, and a kind of compact conformation is provided, and operates steadily, can prevent sideslip that low noise is convenient to install, adjust the link-belt feeder that service efficiency is high.

Link-belt feeder of the present utility model, comprise funnel, deflector chute, the driving chain wheels, impact idler, frame, the idler sprocket group, gate, actuating device, endless rubber belt, cylinder, described driving chain wheels and idler sprocket group are provided with the closed ring combination chain that is driven by the driving chain wheels, and the closed ring combination chain is chimeric by some front and back, about arrange, top and bottom are the Y shape chain piece on plane, branch is located at both sides and constitutes some inner links of two groups of bilateral roller chains and place the pin link plate of inner link both sides to be cascadedly combined by bearing pin on same horizontal surface, and discharging opening one side of described frame is provided with the cleaning mechanism of the annular combination chain of cleaning.

Be provided with the bearing pin of transfer torque between sprocket wheel in described driving chain wheels and the idler sprocket group and belt tensioning drum; Described impact idler two ends are equipped with the rubber belt from deviating block plate; Described cleaning mechanism is by the bar shaped rubber flap that is located at annular combination chain below, fixedly the fork of bar shaped rubber flap and the weight that is located on the fork are formed.

The beneficial effects of the utility model: (1) reasonable integral structure, make easily, volume is little, in light weight, cost is low, convenient transportation; (2) part universality of composition complete machine is strong, easy for installation, and maintenance capacity is little, and the transmission wearing and tearing are little, long service life; (3) have enough intensity and flexibility, its transmission position accurately, steadily, has reliably overcome feed bin material pressure and material and has impacted the conveying machinery damage that brings, and has reduced the loss in efficiency that strap drive skids and produces, and has avoided the deviation phenomenon in the operational process; (4) cleaning mechanism of annular combination chain bottom setting can guarantee the cleaning on combination chain surface, prevents that the feeder discharging is not thorough; (5) driving system is selected the higher chain-driving of mechanical efficiency for use, and system's operation basic load is by roller bearings, so running resistance is little, its required driving power is also little; (6) adopt the electrodeless variable-speed retarder as host driven, thus can be when link-belt feeder move, convenient its running velocity of adjusting.
