1. A mineral powder pellet drying device, comprising a drying box body and a material preparation trough arranged at a top end port of the drying box body, and a feeding port being formed on a bottom wall of the material preparation trough; and further comprising a plurality of rows of shunting buffer assemblies, a plurality of rows of anti-breakage assemblies and a driving assembly arranged on an outer wall of the drying box body;
the shunting buffer assemblies and the anti-breakage assemblies are both arranged inside the drying box body, and the plurality of rows of shunting buffer assemblies and the plurality of rows of anti-breakage assemblies are alternately distributed from a top to a bottom of the drying box body;
each of the anti-breakage assemblies comprises a central rod shaft, an adjusting rod and two anti-falling plates with elastic pads on surfaces thereof;
two ends of the central rod shaft are fixedly connected with inner walls of the drying box body, and the two anti-falling plates are respectively positioned at two sides of the central rod shaft and are in rotating fit with the central rod shaft;
one end of the adjusting rod penetrates through a side wall of the drying box body in a sliding manner and side portions of the adjusting rod are respectively connected with the two anti-falling plates through a push-pull connecting rod in a movable manner;
when the adjusting rod slides on the side wall of the drying box body in an axial direction of the adjusting rod, the two anti-falling plates through the push-pull connecting rod can be driven to swing synchronously in opposite directions;
the driving assembly is disposed on the side wall of the drying box body, the driving assembly is connected with adjusting rods of the plurality of rows of anti-breakage assemblies, and the driving assembly is configured to drive a plurality of the adjusting rods to synchronously slide on the side wall of the drying box body;
each row of the shunting buffer assemblies are linearly distributed at equal intervals, and the shunting buffer assemblies are configured to withstand impact of falling mineral powder pellets in an elastically concave mode and guide the mineral powder pellets to two sides for dispersion; and the side wall of the drying box body is further provided with a hot air blower assembly for introducing hot air flow to an inside of the drying box body.
