Earth-rock conveying device stable in transporting

The invention discloses an earth-rock conveying device stable in transporting. The device comprises a rack, a supporting underframe, a connecting support, a control panel, a power line, a drive roller, a chain, a first motor, a conveying belt, partition plates, a left baffle, a right baffle, a buffer feeding device, sliding troughs and a circulating leveling device. Through the arrangement of thebuffer feeding device, earth-rock materials are fed into a feed bin in advance, through auxiliary buffering of a buffer plate, the earth-rock materials are conveyed into the conveying belt through a feed conveying belt, the materials are gently fed and conveyed, and it is guaranteed that subsequent conveying work is more stable; and the circulating leveling device is arranged, under back-and-forthcirculating pushing of a circulating pushing mechanism, the two sides of a cross frame rod can slide in the sliding troughs through pulleys, a bulldozing plate is driven to move to level earth and rock, the height of earth an
