Deep groove roller group roller group for belt conveyor with large inclination angle

The utility model discloses a deep groove roller group roller group for a belt conveyor with a large inclination angle. The deep groove roller group roller group comprises a baseplate, a cross beam, a roller bracket, side rollers and bottom rollers, wherein the side rollers and the bottom rollers are arranged on two parallel planes respectively; the side rollers and the bottom rollers are arranged in pairs; the two bottom rollers are V-shaped; an included angle Alpha between the axial direction of each side roller and the cross beam are 55 to 60 DEG; an included angle Beta between the axial direction of each bottom roller and the cross beam is 20 to 25 DEG; adjacent side roller and bottom roller are overlapped; and the upper edge of the inner end of the side roller is positioned below the bottom roller surface. The two bottom rollers are V-shaped, and the groove angle of the side roller is larger, thereby increasing the groove depth, improving the clamping force and the friction force of conveyor belts on mat
