ROLLING VEHICLE WITH UNDERBODY COATING Russian patent published in 2022 - IPC E21F13/00 

FIELD: rock mass transportation.

SUBSTANCE: invention relates to the transportation of rock mass from a quarry to a processing plant and can be used for transporting highly moistened, sticking and freezing rock masses to the bottoms of railway transport bodies, namely to dump cars. Movable vehicle with body bottom coating contains a swivel body, which includes a bottom and swivel sides with unloading edges. The flexible tape is placed with a gap above the bottom of the body and two sides. Deflecting drums are installed on the unloading edges of the bottom of the body. The unloading edges of the turntables are equipped with drums. One end of the open rubberized tape is fixed and wound into a roll on one drive drum, and the opposite end of this tape is fixed on the other drive drum with the possibility of winding on it when the drive is turned on.

EFFECT: exclusion of contact of the bottom of the movable vehicle with the rock mass and provision of movement together with the belt under the action of its own weight; ensuring almost complete unloading of the body from stuck and frozen rock mass with a slight slope reduces the unloading time, which allows increasing the number of flights, invention also makes it possible to unload the rock mass without tilting the body, and if necessary, it is possible to remove the proposed coating and install it on another mobile vehicle.
