Detailed Description
The following description of the technical solutions in the embodiments of the present invention will be clear and complete, and it is obvious that the described embodiments are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Referring to fig. 1 to 6, an embodiment of the present invention includes:
a split bottom dump truck comprising: the truck comprises a bottom door 4, a truck bed 2, a first bogie 5 and a second bogie 3, wherein the second bogie 3 comprises an axle 33, unloading wheels 32 and wheels 31, the wheels 31 are arranged at two ends of the axle 33, the unloading wheels 32 are arranged in the middle of the axle 33, the bottom door 4 is arranged below the truck bed 2, and the front end of the bottom door 4 is hinged with the truck bed 2 through a pin shaft, so that the bottom door 4 can be conveniently opened and closed.
The first bogie 5 is arranged at the front end of the lower part of the bottom door 4, the second bogie 3 is arranged at the rear end of the lower part of the bottom door, the middle part of the rear end of the upper surface of the bottom door 4 is provided with a diversion flap 11 extending upwards in an inclined way, the two sides of the diversion flap 11 are symmetrically provided with a downhill surface respectively, and when in discharging, due to the adoption of the diversion flap 11 structure, mineral aggregate slides down along the downhill surface, the falling track avoids a discharging curved rail, mineral aggregate accumulation on the discharging curved rail is greatly reduced, so that the mine car runs more stably, and the service life of the discharging curved rail is prolonged.
The rear end of the bottom door 4 is provided with a lower guiding device 21, and the rear end of the carriage 2 is provided with an upper guiding device 22 corresponding to the lower guiding device 21.
