Detailed Description

The following describes the embodiments of the present invention in further detail with reference to the accompanying drawings.

As shown in fig. 1-3, the overall structure of the waste steel bar rolling shear of the present invention is schematically illustrated, the main body is a rolling shear device 2, which is a double-shaft rolling shear device, and has 2 single-side rolling shears 21 arranged transversely; the single-side rolling scissors 21 are provided with a plurality of rolling scissors blades 22 which are fixed on a rolling scissors shaft 23 and driven to rotate by an external driving device; 2 single-side rolling shears 21 rotate inwards relatively to form a rolling shear area 24, waste steel bars are rolled in, and are mutually matched by rolling shear blades 22 to be cut into steel bar sections convenient to recycle.

And a feed hopper 1 is arranged above the rolling shear device 2 and can be used for intensively placing the waste steel bars to be treated.

And a discharge hopper 3 is arranged below the roller shear device 2 and used for gathering and discharging the sheared steel bar sections.

And a discharging belt conveyor 4 is arranged below the rolling shear device 2 and is used for outputting the steel bar sections outwards, so that the steel bar sections are convenient to recover.

The steel bar sections subjected to roll shearing can be discharged from the middle roll shearing area 24 along with the rotation of the single-side roll shearing machine 21, and a certain tangential acceleration can be generated in the discharging process; when a double-shaft rolling shear device is used in the past, materials are generally discharged to the ground or in a material collecting frame.

However, when the discharge belt conveyor 4 is used for continuous conveying, the discharged steel bar segments are smashed to the surface of the conveying belt 41, so that the belt is easily punctured and cracked, and the service life of equipment is influenced; therefore, a special discharging hopper 3 is needed to be matched with the discharging belt conveyor 4, and the damage influence of the reinforcing steel bar section on the conveying belt 41 is reduced. As shown in fig. 4, the discharge hopper 3 is provided with a buffer inclined plate 31, which is obliquely arranged, and the horizontal projection direction spans the whole roller shear area 24, so that the discharged rebar segment drops on the buffer inclined plate 31 after coming out of the roller shear area 24, most of the downward kinetic energy of the rebar segment is absorbed by the buffer inclined plate 31, then slides downward, slides to the conveying belt 41 from the discharge port 32, and is output outward. Preferably, the downward inclination direction of the inclined buffer plate 31 and the conveying direction of the conveying belt 41 are the same direction, and the reinforcing steel bar segments fall on the conveying belt 41 at a certain initial speed in the same direction, so that the relative speed difference is reduced, and the impact force is also reduced.

Further, as shown in fig. 3 and 5, since the single-side rolling shears 21 are longer than the width of the conveying belt 41, the discharge hopper 3 is further provided with a material collecting plate 33, preferably 2 material collecting plates 33, for collecting the reinforcing steel bar segments produced at both sides of the rolling shears device 2 to the middle, and then sliding to the vicinity of the buffer inclined plate 31 to be discharged to the discharge belt conveyor 4 through the discharge port 32.

Furthermore, the height of the discharge port 32 of the discharge hopper 3 relative to the conveying belt 41 is adjustable, and the height can be reasonably adjusted according to the installation condition of the discharge belt conveyor 4 on site, so that the damage impact of a reinforcing steel bar segment on the conveying belt 41 is reduced as much as possible. As shown in fig. 5, the discharge hopper 3 is mounted on the frame through a height adjusting device; a fixing device 34 is arranged above the discharge hopper 3, a height adjusting hole 35 is formed in the rack, and the fixing device 34 can select the height adjusting hole 35 with the corresponding height to install and fix according to needs, so that the installation height of the discharge hopper 3 can be adjusted; make discharge gate 3 can adapt to not co-altitude ejection of compact belt feeder 4, guarantees that the distance between blanking mouth 32 and the conveyor belt 41 upper surface is as little as possible to reduce the impact of reinforcing bar section to conveyor belt 41, the protection belt.

The waste steel bar rolling shear of the utility model rolls and shears the waste steel bars to the middle through the double-shaft rolling shear device, and then discharges the waste steel bars from the middle; be equipped with out hopper 3 below the escape way, go out hopper 3 and be equipped with buffering swash plate 31 for cushion the exhaust reinforcing bar section, then fall discharge belt machine 4 on, discharge the reinforcing bar section, conveniently concentrate the collection.
