The lower end of the hydraulic cylinder 20 is fixedly connected to the fixed seat 22. In addition, it is noted that the tipping device can share a hydraulic system with the cold rolling transverse cutting unit.

The specific using process is as follows: when using, the jar pole of pneumatic cylinder 20 is flexible to the shortest time, divide strip belt 2 to be in the horizontality just in this moment, when the jar pole of pneumatic cylinder 20 begins upwards to stretch out, the backup pad 18 is pushed up on the jar pole, backup pad 18 begins to rotate downwards around the pivot 25 that tumbles, and then it is rotatory to drive base 3, because eight belt support 1 are whole to be fixed on base 3, just so can realize the upset of whole belt feeder, along with constantly stretching out of the jar pole of pneumatic cylinder 20, when the jar pole extends for the longest time, divide strip belt 2 to rotate 90 degrees just in time this moment, just so can give up the maintenance space, the flying shear 16 of being convenient for is changed and is cut sword and maintenance.

Another difference is that in this embodiment, the coupling 8 is also split, the coupling is divided into a first coupling 81 and a second coupling 82, and the joint between the first coupling 81 and the second coupling 82 is a vertical flat joint.

The working principle of the invention is as follows:

after the novel belt conveyor provided by the invention is arranged on the flying shear 16, the slitting belt 2 and the flying shear rear supporting plate 17 are arranged in a staggered manner, the length of the minimum shearable steel plate is shortened, the shearing size is shortened from 350mm to 240mm, the shearing specification is enlarged, and the shearing processing capacity is increased; the transmission of the slitting belt 2 is synchronous with the movement of the steel plate during shearing, and the sheared steel plate directly falls on the slitting belt 2 after leaving the shearing edge instead of directly falling on the flying shear rear supporting plate 17, so that the problems that the flying shear rear supporting plate 17 is unpowered and the steel plate is easy to scratch the lower surface are solved.
