The NJZ low speed backstop fully combines the design characteristics of the upper belt conveyor, and fully solves various design deficiencies of the general backstop through continuous improvement.
The backstop can effectively prevent the conveyor from retrograde accidents caused by the gravity of the material. In the backstop state, the entire drive device is still in the loaded state, which will not affect the maintenance and replacement of the drive components, and has a reliable safety protection effect on preventing retrograde accidents caused by the wear of the drive system. The backcheck is composed of a plurality of wedges evenly distributed, and the contact area is large and the backcheck torque is large, which is more safe and reliable. The raceway between the inner and outer wheels adopts bearing and roller double positioning support, which has stable operation and low resistance. The interior is lubricated with thin oil, which reduces the coefficient of friction and prolonging the service life of the backstop. Unique anti-rotating arm split design, easy installation, belt machine maintenance or other need to reverse, only need to carry out a simple operation to achieve.
