Technical Field

The utility model belongs to the technical field of transportation loading and unloading, and particularly relates to a system for unloading, dust collection and cargo extraction of a bridge van unloader for powdery materials.

Background

When the existing powdery materials such as cement, coal dust or fly ash are transported from a production place to a use place, the materials are transported to a designated place by a transport vehicle, and then the powdery materials are transported into a finished product warehouse by a lifting machine. For the unloading part in the process, the applicant applies for a patent with application number of CN202022325678.5 in the 10 th month of 2020, and the patent name is a fixed powder unloading system, wherein a car unloader is arranged in a car unloading room and comprises a supporting plate and a telescopic supporting rod; the support rod is arranged below the front end of the support plate. When the powder material unloading device is used, the powder material is filled into a transport vehicle, and the transport vehicle transports the powder material to an unloading room; before the supporting plate is supported by the supporting rod of the unloading machine, the supporting plate is horizontally paved on the ground, and the supporting rod is positioned underground. After the transport vehicle is backed up and enters a unloading room and is parked above a supporting plate of the unloading machine, a driver gets off the vehicle, and a supporting rod is remotely controlled to prop up the front end of the supporting plate, so that the head of the transport vehicle is lifted higher than the tail of the vehicle; when the supporting plate is lifted to a designated position, the rear door of the transport vehicle is controlled to be opened, and unloading is started. While this approach allows for discharge, during actual use the inventors have found that: when the car unloader lifts the transport vehicle by a certain angle, the top of the transport vehicle is very close to the top of a car unloading room. In reality, in order to avoid collision between the transport vehicle and the unloading room, the unloading room needs to be built very high, so that the construction cost of the unloading room is very high.
