Background
The existing mining wide-body dumper is mainly used for transporting ore materials after mine blasting, the mining wide-body dumper generally adopts a freely rotating upturned carriage tail gate, when the dumper is used for unloading the ore materials, the carriage tail gate is always kept vertically downwards under the influence of gravity, the ore materials are discharged only by a gap formed between the carriage and the tail gate when the carriage is lifted, and the gap is gradually increased along with the larger lifting angle of the carriage. At this time, the clearance between the carriage and the tail gate, which is generated by the lifting angle of the carriage capable of naturally dumping the ore material, cannot meet the requirement of smooth unloading of the ore material (the particle size of part of the ore material is larger), so that larger ore material is often clamped between the carriage and the tail gate, and meanwhile, part of finely crushed ore material cannot be smoothly discharged into the bin due to the blocking of the tail gate and is directly spilled outside the bin, so that the utilization space of the bin is insufficient, the manual cleaning workload is increased, and the unloading efficiency is low. And the large-block-diameter ore material continuously impacts the tail gate of the carriage, so that the tail gate is easy to deform and damage, the maintenance cost is high, the tail gate of the carriage is a free rotation process when the carriage returns to the original position after the ore material is unloaded, and if the carriage returns to the original position at an excessive speed, the tail gate and the carriage or the hook are easy to mutually impact, so that the tail gate is deformed and damaged again.
The automatic lifting opening and traction closing device for the tail gate of the self-unloading wagon box is developed to solve the problems.
