The engineering machinery integration of operation such as machine, belt conveyor, composition are filled, are transported, unloading production line, carry out the handling fortune of the earthwork, sandstone, bulk cargo
Defeated work.
In recent years, with the fast development of Chinese national economy, the demand to dumper has greatly increased.Even if self-unloading
The quantity of vehicle is more and more, and the frequency of use of dumper is also higher and higher, and use environment also has the tendency that the severe of change, the same day
When gas cold, the soil or coal of transport will be generated with the bottom plate in compartment freeze, and when unloading, freeze on bottom plate
Object is difficult to unload, serious to affect rate of discharging, has an impact to the operation of dumper；The compartment of conventional dumper is in goods
Under the frequent pinch shock abrasion of object especially bulk cargo, the phenomenon that causing compartment to deform, is very serious, even results in compartment
The tearing of plate is failed, and the service life of vehicle is seriously affected；When the bulk goods of transport is in moist, tacky, not loose feelings
Under condition, institute's freight glide speed can very slow, or even can sometimes topple over not completely, be not thorough, it is also necessary to people
Power is cleared up again, this improves transportation cost with regard to the serious service efficiency for affecting vehicle；In addition, our company's production
Dumper exports the states such as New Zealand, and there are standard requirements on road to the length of trailer on external dumper, in order to realize that scene fills more
It carries but meets standard path again and then need to improve the trailer of dumper.
By the retrieval to existing patent document, publication similar with technical solutions of the utility model is not found
Document.
