Technical Field
The invention relates to the related field of ship unloaders, in particular to a material blocking mechanism for a material discharging opening of a hopper of a ship unloader.
Background
At present, on a wharf for ore transportation, intermittent ship unloaders are more than bridge ship unloaders with bucket door machines and grab buckets, wherein the bridge type grab ship unloaders have obvious advantages in the aspects of adaptability to ore materials and ships, operation cost, prevention of damage to the ship unloaders caused by ship jolts due to waves and the like, so that the bridge type grab ship unloaders are most widely applied in the use of the ship unloaders formed in recent years.
The hopper of the bridge grab ship unloader is used for centralizing and evenly dropping ore materials grabbed by the grab on a conveyor belt below the hopper. When the grab bucket opens, ore materials fall from the grab bucket into the hopper and then fall onto the conveyor belt.
Because there is the clearance between feed opening and the conveyer belt of hopper bottom, consequently in the unloading in-process, the material is splashed out from the clearance between feed opening and the conveyer belt easily to can produce more smoke and dust. The existing mode of reducing smoke and material overflows is to increase the fender skin in the outside of the feed opening of hopper body, as shown in figure 1, and it can play the effect that reduces smoke and material and overflows to a certain extent.
However, because the vertical height of the grab bucket from the conveyor belt is longer, and the grab bucket grabs more material every time, therefore, during blanking every time, the impact and the pressure of the material to the fender skin are great, and the fender skin can produce the deformation under the effect of impact and pressure to make the bottom of fender skin move downwards, contact the conveyor belt and produce friction with the conveyor belt, lead to the wearing and tearing of fender skin faster, need frequent change.
The gear shifting skin must stop the ship unloader, thus reducing the production efficiency to some extent.
