Description

The quantitative apron feeder of dynamic weighing formula
Technical field
The utility model belongs to loose unpacked material and reprints feed and quickly ration loading equipment, specifically relates to the quantitative apron feeder of a kind of dynamic weighing formula.
Background technology
Along with the raising of bulk transport system degree of automation and the raising of load transfer device efficient, production capacity constantly enlarges in recent years, and in coal and various material storage-transportation unit, car loading operation is very busy.In order to improve entrucking precision and efficient, reduce the wastage, alleviate working strength of workers, use the automation entrucking to seem very necessary.
At present, the apron feeder of weighing generally is made up of adhesive tape type feedway and gauging device, and the carrying roller of adhesive tape type feedway adhesive tape is for lifting roller; In order to improve feeding coal and to prevent that material is unrestrained, the adhesive tape type feedway generally adopts the rubber conveyer belt of both sides band wave rib, still; Because load-transfer device both sides wave rib height is limited, under the certain situation of belt speed, its feeding coal is less; It is bigger to take up room; Feeding coal but can not increase substantially, and delivery system is to the requirement of reprinting feeding device charge efficiency and the precision metering traffic capacity of existing installation head and shoulders above, and the apron feeder of weighing of prior art can not satisfy the requirement of big feeding coal.
Only have material and reprint the apron feeder of feed function, make the feed section big owing to have higher deflector chute, so feeding coal is big, and feed has satisfied the demand of current material-transporting system to big feeding coal evenly, continuously.Because loose unpacked material has certain slope angle of repose and quiet slope angle of repose greater than moving slope angle of repose, at the apron feeder feed end, begins from Hatch Opening; To piling up institute's region covered with moving slope angle of repose, material is to the pressure of load-transfer device, except that receiving the solid accumulation effect of altitude; Also receive the influence that press in the storehouse and the storehouse pressure fluctuates, this zone can be described as the storehouse nip, at place, the nearly emptying point of apron feeder discharge end; Material is inwardly piled up with moving slope angle of repose from the emptying point, and material receives the influence of discharging unstable to the pressure of load-transfer device, and this zone can be described as discharge zone; These two regional materials receive multiple factor affecting to the pressure of load-transfer device, change bigger.Present apron feeder design when satisfying big feeding coal, makes every effort to reduce volume and weight; The feeder fuselage designs is shorter, and storehouse nip and discharge zone are connected basically, as being the increase function of measuring; Below the load-transfer device of apron feeder, gauging device is installed,, is made metering result's precision lower owing to receive storehouse nip and discharge zone to the influence that load-transfer device pressure changes; Error is bigger, can't reach the requirement of material-transporting system to precision.Avoid the influence of storehouse nip and discharge zone in order to make weighting apparatus; Improve weighing precision; The fuselage of lengthening feeder part; Make storehouse nip and discharge zone at a distance of certain distance, between storehouse nip and discharge zone, form the zone that one section load-transfer device pressure does not only have storehouse pressure influence but also do not have discharging to influence.The regional load-transfer device pressure of this section only receives the material gravity effect, and pressure is basicly stable, can be described as the stable region.
The installation of LOAD CELLS and making precision; Directly influence the measuring accuracy of dynamic weighing apron feeder, Chinese patent 200920159114.5 disclosed " dynamic weighing apron feeder ", LOAD CELLS adopts ball pivot to be connected with claiming frame; Claim that frame adopts girt to limit the swing of its LOAD CELLS ball pivot; The synergy of pull bar and ball pivot, make claim frame and on weighing carrier roller only can guarantee that gravity is added on the LOAD CELLS smoothly in movement in vertical direction.Above-mentioned title body structure belongs to direct bearing-type.In use, because there is mechanical wear in ball pivot, there is more moving mechanical part; Dynamic response property is poor, and the metering sensitivity is lower, needs regular maintenance adjustment weighting apparatus zero point; And the non-general technology workman of maintenance adjusting work can accomplish, needs very technical professional.When weight of material on the speed of belt operation and the belt changes than greatly the time, can produce some additional errors, promptly weighting apparatus stability is very poor, and the slight impact of material will cause the weighting apparatus error.
Coal industry is to storehouse quantitative down automation, the intelligent comprehensive demands for higher performance of entrucking fast.The feeder of use under coal store, the reliable and stable operation of feeder and more convenient equipment repair and maintenance directly influence the production efficiency and the economic benefit of coal industry, play crucial effects in order to what guarantee to produce.
