Abstract

The invention provides a waste steel conveyor and aims at solving the problem that waste steel resources used as a second mine industry of the iron and steel industry have the advantages of energy saving, pollution reduction, environmental protection, recycling and the like, are widely applied and are in corresponding urgent need of high-efficiency waste steel treatment equipment. The waste steel conveyor is characterized by comprising a chain plate device, a stand guide material baffle device, a funnel, a chain support device and supporting legs, wherein the stand guide material baffle device consists of a horizontal section and an inclined lifting section; the funnel is jointed with the front end of the stand guide material baffle device; and a floor board of the stand guide material baffle device is the chain plate device. A chain wheel of a main shaft is driven by a motor and a speed reducer thereof in a driving device to rotate, and a chain plate of a chain is driven by meshing the chain below the chain plate with the chain wheel to move, so that a certain height can be lifted in the moving process and the waste iron and steel on the conveying chain plate is conveyed to a crusher.

Description

Waste steel conveyor

Technical field

The present invention relates to a kind of apron conveyor, specifically is the apron conveyor of carrying broken iron.

Background technology

The steel scrap resource has energy savings, reduces pollution, protects advantages such as environment, recycle as " second-mining industry " of steel and iron industry, is subjected to widespread use, correspondingly is badly in need of efficient steel scrap treatment facility.Waste steel conveyor is exactly the key equipment in this cover technological process, by this equipment steel scrap is transported to and carries out fragmentation in the crusher.Because the steel scrap disposal system can not be used feed bin, thus require the afterbody of this conveyer not only to have the function of horizontal bin stock, but also require transporting chain plate in course of conveying through bending certain angle, flow to crusher after material risen to certain height.

Summary of the invention

For achieving the above object, the invention provides a kind of waste steel conveyor.The afterbody of waste steel conveyor is designed to have 8 meters long horizontal bin stock section, then by the certain angle of frame guide baffle plate bending, drive the rotation of main shaft upper sprocket wheel by electrical motor in the actuating device and retarder thereof, the carrier bar that the engagement of chain and sprocket wheel drives on the chain below the carrier bar moves, in moving process, promote certain height, give crusher the material on the transporting chain plate.Waste steel conveyor also can be because of the material unbalance loading cause the carrier bar sideslip, and simple for structure, easy to use.

The object of the present invention is achieved like this: it comprises chain panel assembly, frame guide damper gear, funnel, holder chain apparatus and supporting leg;

Frame guide damper gear is made up of horizontal segment and tilt-lift section, and horizontal segment comprises the tension frame; The front end (most significant end) of funnel and frame guide damper gear is connected, and " floor " of frame guide damper gear is the chain panel assembly;

Said chain panel assembly comprises chain transmission system and actuating device thereof, take-up device.Actuating device is installed two above drive sprockets on the output shaft of (being driven by variable-frequency motor) retarder; Carrier bar be fixed on chain above, chain is a bush roller chaiin, roller rolls in orbit and drives the carrier bar motion; The take-up device of chain transmission system is, the both sides plain bearing housing is installed in the upper and lower slideway of two sides of tail tension frame, one end of spiral pull bar passes the inboard of tension frame and cooperates with nut, the spiral pull bar other end is fixed on the plain bearing housing, make the mode of the outside top of spiral pull bar plain bearing housing strain chain by adjustment nut, like this spiral pull bar is counter mounted in the equipment, can avoids the steel scrap scratching with it in stock ground.

Ask chain apparatus to be, have plurality of carrier rollers to support below the backhaul carrier bar, carrying roller is installed on the frame.

Compared with prior art, the invention has the beneficial effects as follows: the load transfer device in handling as steel scrap, satisfying under the situation of environmental demands and steel scrap can being transported in the crusher reliably, simple for structure, easy to use.

The specific embodiment

Referring to Fig. 1, it comprises funnel 1, frame guide damper gear 3, chain panel assembly, holder chain apparatus 7 and supporting leg 6;

Frame guide damper gear is made up of horizontal segment and tilt-lift section, and horizontal segment comprises the tension frame, and the front end (most significant end) of funnel and frame guide damper gear 3 is connected, and " floor " of frame guide damper gear is the chain panel assembly;

Said chain panel assembly comprises chain transmission system and actuating device thereof, take-up device, referring to Fig. 2, actuating device is installed four drive sprockets 10 on the output shaft of (being driven by variable-frequency motor) retarder 9, four bush roller chaiins 13 have correspondingly been fixed below the carrier bar 11, can make transmission shaft stressed more even like this, and the load that every chain is born diminishes, and can select the chain of ting model; Referring to Fig. 3,4, roller on the chain 13 and driving chain wheel engagement, referring to Fig. 5,6, roller rolls on track 15 and drives the carrier bar operation, article four, the roller on two chains in the bush roller chaiin outside is that belt wheel is along 121, play the effect of cross spacing in the time of when it is rolled in orbit, with the engagement of sprocket wheel, can not cause the carrier bar sideslip because of the material unbalance loading.

Referring to Fig. 6; frame guide damper gear is made up of horizontal segment and tilt-lift section; joining place guide baffle plate at the two needs angle of bending; be subjected to the restriction of on-the-spot operating environment; the radius of curvature of frame bending part can not be too big; so transporting chain plate might produce " chain wafts " phenomenon when promoting; again because frame and striker plate design all-in-one-piece; carrier bar 11 moves in baffle plate 3; for preventing the two friction; need between carrier bar and baffle plate, to reserve certain clearance, but just might produce Lou material phenomenon like this, for this reason; (being 10mm place, carrier bar top) fixes the wear-resisting pressing plate 14 of a row respectively with bolt on the striker plate of both sides; so promptly prevented " chain wafts " phenomenon, avoided again leaking material, also played protection both sides striker plate simultaneously and reduce its worn-down effect.

Referring to Fig. 7, whole carrier bar laterally is made up of some stripe board, for making carrier bar can adapt to arc, need between the adjacent bar plate, to leave the slit, in case carrier bar produces extruding mutually between the stripe board when entering segmental arc, but material can't be leaked at linear portion in this gap, thus each stripe board edge fit is designed to stepped appearance 16, reserve certain clearance δ 2 between adjacent two stripe board during assembly unit.

The take-up device of chain transmission system is (referring to Fig. 1), the plain bearing housing of both sides is installed in the upper and lower slideway of tension frame of two sides of tail, one end of spiral pull bar 4 passes the inboard of tension frame and cooperates with nut, the other end of spiral pull bar is fixed on the plain bearing housing, mode with outside (right side) top of spiral pull bar plain bearing housing is strained chain, like this spiral pull bar is counter mounted in the equipment, can avoids the steel scrap scratching with it in stock ground.

The holder chain apparatus has some idler pulleies 7 to support below backhaul carrier bar 8, and idler pulley is installed on the frame.
