Description
Technical field
The utility model relates to a kind of conveying feeding device, relates in particular to a kind of scraper plate and carries feeder.
Background technology
Feeder is one of capital equipment of coal mine production system, and the reliability of feeder directly influences the normal operation of whole production system.The feeder of mine coal bunker mainly contains reciprocating type feeder of K type and first belt feeder at present.Wherein, the structure and the operating principle thereof of the reciprocating type feeder of K type are: be provided with a deflector chute in the feed bin bottom, the base plate of this groove is movable.Drive the base plate iterative motion by power set, 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 acting in conjunction of internal pressure and inside and outside frictional 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.It is bigger that the reciprocating type feeder of K type is specially adapted to fire damp concentration, the feed bin bottom feed of easily blasting.Shock-resistant, advantages such as feed stable, long service life that these facility have have been widely used in industries such as electric power, coal, mine, building materials, metallurgy.The structure of First Tape Feeder and operating principle are: deflector chute is set below feed bin, first is installed below deflector chute brings materials device, first brings materials device and is made up of component such as head roll, impact idler and support, changed course cylinder, first band, adhesive tape, tensioning apparatus; Drive unit is made up of motor and inorganic variable speed reducer, and drives head roll by chain drive; First brings materials device and drive unit is installed on the underframe.During work, the material in the feed bin enters deflector chute and drops on the first band, the final inner frictional force of material when the first band is static and stop motion forms the static accumulation of certain angle at discharging opening; When beginning to rotate under the driving of head roll at drive unit, drive tape movement, adhesive tape drives the first band motion on it, the first band drives the material guiding discharging opening on it, operating first band turns to backhaul after the discharging opening discharging, material is constantly discharged from discharging opening, thereby finishes the feed process.These facility have that power is little, light weight, feeding coal is big, feeding coal is stable, easy to adjust, advantages such as noise is little, maintenance capacity is little, parts highly versatile.
Along with the continuous development of coal industry, reciprocating type feeder of K type and first belt feeder expose some shortcomings gradually.Wherein, the shortcoming of the reciprocating type feeder of K type is: 1. adopt crank-link mechanism design, can only the process feed, and backhaul space-time returns, and feed is inhomogeneous, and makes belt wave operation under the storehouse, seriously restricts transport power; 2. the feeder base plate needs to bear the very big frictional force of material in backhaul, so need bigger driving power, energy consumption big; 3. feeder power demand and structure stress are big, and weight of equipment is big; 4. the feed process is to move back and forth, and vibration equipment is big, and noise is also big; 5. structure stress is big, the movement parts quick abrasion, and maintenance capacity is big; 6. feed is discontinuous, and production efficiency is lower; Nature blanking when 7. the down-hole coal bunker is connected blanking with reciprocating type feeder, drop is big, coarse coal is many, coal supply is reciprocal operation, contraction type blanking in addition, tend to cause stifled, the scaffold phenomenon of coal bunker gas, and get rid of difficulty, and the down-hole adopts generally that skewer is disclosed, the high pressure wind, and often effect is little, stifled storehouse rate is than higher, and influence is produced and normally carried out; Easily cause personnel's hidden danger during also recruitment operating personnel's labour intensity, and processing canopy storehouse.The shortcoming of first band feeder has: 1. structural member kind and quantity are more, safeguard complexity, safeguard that part is more; 2. the two sides sealing is bad, the leakiness material; 3. the first band is assembled by long and short flap of more piece cast iron and nylon, material is above feed bin is fallen the first band in operation process, when it is used in run coal bin place, down-hole, because regular meeting is mingled with materials such as some coarse coal spoils, steel ripping bar, big wooden stick during the raw coal in the run coal bin, can smash the first band because of foreign material impact during material feeding; 4. the tension adjustment of first band is more frequent, and rate of tension is regulated and is difficult for grasping, and regulates pine, is prone to the skidding of first band; Regulate tension, then can increase energy consumption of electrical machinery.Therefore, the use of first band feeder is very limited, and only is only applicable to thin homogeneous material and the less occasion of impact force.
