The invention discloses a belt-type sintering machine for preventing arching. The belt-type sintering machine structurally comprises a head and tail star wheel, a feeding hopper, an ignition furnace,a trolley, an exhaust fan, a sieve frame, a machine tail wheel shaft, an anti-arching horizontal transporting device, a machine seat, and a sliding caterpillar track, and the head and tail star wheeland the machine tail wheel shaft are respectively arranged at the two ends of the upper portion of the interior of the machine seat. According to the belt-type sintering machine for preventing arching, a valve core shaft and a hub are mounted in a penetrating and embedded mode through an outer wall inserting piece, so that the machine tail wheel shaft drives an embedded gear to together rotate andoutput the transshipment during moving, then a disc body interior trapezoid shape core column is used as the guiding through connecting shaft heads on the two sides of a rod column so that the rotation speed of the embedded gear is increased through the circulating rolling friction under the unchanged position condition, and the sufficient power is attached to the disc body interior trapezoid shape core column accordingly; and by using the buckling fit of edge wall oblique teeth and the sliding caterpillar track, the force is applied to each chain groove in the transmission step by step for traction so as to prevent the track arching, and through the connection of a fastening ring and a machine seat side end track connecting piece, a lead screw operates step by step through the support ofan elastic column to buffer the trolley so as to continue to work.
