Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature; in the description of the present invention, "a plurality" means two or more unless otherwise specified.
The embodiment of the utility model provides a blast furnace belt conveyor system of function of rectifying in area, including 1 machine of belt, 1 machine of belt includes support and belt 1, it has head pulley 2, tailwheel 3 and bend wheel 4 to articulate on the support, 1 belt walks around head pulley 2, bend wheel 4 and tailwheel 3 in proper order and forms the closed loop, is located 1 upstream department of belt of head pulley 2, tailwheel 3 and bend wheel 4 all is equipped with forces rectifying structure 6, force rectifying structure 6 including gate-type bracket 8, gate-type bracket with the scaffold weldment, rotatable installation has first roller and the second roller of rectifying on the gate-type bracket 8, first roller and the second roller of rectifying respectively with reserve the interval between 1 both sides of belt, just first roller and the second roller of rectifying central line of rectifying all with 1 direction of travel of belt is perpendicular.
Therefore, as shown in fig. 1 and 2, the belt 1 rotates clockwise, the material falls onto the belt 1 from the receiving chute, and is transported to the head pulley 2 along the running direction of the belt 1, and the forced deviation rectifying structure 6 is arranged in front of the head pulley 2 and comprises two symmetrical deviation rectifying rollers 7 erected on two sides of the belt 1, the belt 1 can generate shaking deviation in the transportation process, and when the belt 1 is laterally deviated to abut against the deviation rectifying rollers 7, the belt 1 rotates together with the deviation rectifying rollers 7, and meanwhile, the belt 1 is extruded, so that the belt 1 moves to the original position, and the purpose of forced deviation rectification is achieved. Wherein, overspeed device tensioner 5 plays the effect of indefinite tensioning belt, belongs to prior art.
The forced deviation rectifying roller belongs to the deviation correction of a hard contact rubber belt and has no self-adaptive mechanism. For the belt 1 which is frequently deviated, the side edge of the belt 1 is frequently contacted with the forced deviation rectifying roller, so that the side edge of the belt 1 is worn too fast. But the device is more reliable, ensures that the deviation of the belt conveyor cannot exceed the set limit.
In a preferable scheme, the head wheel 2, the tail wheel 3 and the direction-changing wheel 4 are connected with the support through maintenance-free bearings. The oiling period of the bearing seat assembly can be prolonged to 2 years, and the maintenance workload can be greatly reduced. On the other hand, the dilemma that potential safety hazards such as mechanical damage of maintenance personnel are easily caused due to difficult oiling caused by space position limitation (such as tightly hanging a bend wheel, a pit belt and the like) is also avoided.

Preferably, a DH series non-contact slipping switch is arranged on the belt 1. It follows that the DH series non-contact slipping switch operates by detecting a periodic variation in capacitance at its probe. If the end surface or the circumferential surface of the driven shaft or the wheel has 'unevenness', the slipping switch probe is only required to be installed opposite to the position with unevenness; if the 'uneven part' (the end surfaces of the shaft and the wheel are flat and the circumferential surface is uniform and smooth) cannot be found, only an 'uneven point' (a small thin metal sheet is additionally attached to the detected surface) is artificially manufactured at the detection part of the shaft and the wheel. When the motor rotates, the driven shaft and the wheel are driven to rotate by the rotating device, and the slipping switch keeps a closed state when detecting the periodic change of the capacitance of the probe. When the equipment has faults of jamming, stalling, slipping of the belt 1, falling of the transmission belt and the like, the driven shaft rotates slowly or stops rotating, the change period of the capacitance of the probe detected by the slipping switch is obviously prolonged, if the period exceeds twice of the normal change period, the slipping switch is switched from a closed state to an open state.
Preferably, an H-shaped cleaner 10 is disposed above the head pulley 2, a P-shaped cleaner 11 is disposed below the head pulley, and the H-shaped cleaner 10 and the P-shaped cleaner 11 are respectively disposed at the upstream and the downstream of the belt 1.

Therefore, the installation positions of the two ends of the shaft of the deviation rectifying roller are adjusted, the clamping blocks are inserted into different clamping grooves, so that the included angle between the deviation rectifying roller and the belt 1 can be adjusted, the included angle is properly reduced after the abrasion of the belt 1 is increased, the deviation space of the belt 1 is further reduced, and the belt 1 is prevented from vibrating or deviating.
In a preferable scheme, a circular connecting flange plate 9 is arranged at the tail end of the door type bracket, and the circular connecting flange plate 9 is connected with the rack through bolts. As shown in fig. 3 and 4, the circular connecting flange 9 can rotate at any angle to be connected with the frame bolt, and the installation angle of the rectification roller can be realized through rotation, so that the included angle between the rectification roller and the belt 1 can be changed.
Preferably, the door type bracket is connected with the frame in a welding mode.
According to the preferable scheme, protective devices are additionally arranged near the head wheel 2, the tail wheel 3 and the bend wheel 4, and a man-machine isolation protective net is additionally arranged at the rotating wheel of the belt 1 machine, so that the isolation of moving parts from operators is realized, and the safety of the operators is ensured.
