In the moisture more mines of some nature of coal of our country, still cant accomplish complete unloading while fighting with dustpan, the dustpan cant be unloaded clean because of the seizing of coal while fighting. This reduce transportation efficiency on one hand, can cause, also overload seriously load, next time on the other hand. Mine actual production scene of lifting machine, because manual operation or unload netly or repeat a certain reason loading or others lead to the fact the dustpan to fight and overload often, no matter which kind of reason lead to the fact dustpan fight, overload, lifting machine serious threat of security all. This design carries on on the basis of this. It can be used in all kinds of mine lifting machines. Use the device can prevent from lifting machine whom dustpan fight overload and unload incompletely seriously in the course of transporting effectively, have dispelled the direct hidden danger of the accident of the lifting machine, thus improved the dependability of the lifting machine greatly, reduce the accident, prevent casualties, and improve the transportation efficiency of the lifting machine greatly.
