The invention discloses a chain transmission conveying device suitable for dry areas. The chain transmission conveying device comprises a housing, wherein a first rotating rod is fixedly connected toone side of the inner wall of the housing by virtue of a first motor, a second rotating rod, a third rotating rod and a fourth rotating rod uniformly sleeve the outer side of the first rotating rod, driving chains are in driving connection to one end, which is far from the first rotating rod, of the second rotating rod, the third rotating rod and the fourth rotating rod by virtue of first gears, afirst gear track is formed in one side of the first gears, a traction device is in driving connection to the inner side of the first gear track, and a cleaning box is fixedly connected to one end ofthe top of the inner wall of the housing. The invention relates to the technical field of mechanical driving equipment. According to the chain transmission conveying device suitable for dry areas, sundries attached to the driving chains can be effectively removed, the loss caused by a sundries pile cleaning device is reduced, obstacles on a forward path can be crushed, and additionally, the driving chains can be prevented from falling off from the gears.
