Summary:The utility model discloses a precoated sand conveying system. A first pipeline and a second pipeline are arranged; due to the fact that the precoated sand is small in particle, large in specific gravity, dry and small in friction force, the flowability of the precoated sand is good, when the precoated sand is transported, the precoated sand can flow in the first pipeline and the second pipeline under the action of gravity, mechanical transportation can be reduced, the cost can be saved, and the production efficiency can be improved. By arranging the upper limiting mechanism and then arrangingthe hanging ball in the upper limiting mechanism, the upper limiting mechanism can work to drive the hanging ball to move up and down, so that a worker obtains the height of the precoated sand in thesand bin according to the distance between the hanging ball and the upper limiting mark, and whether the sand feeding work is stopped or not is judged. 本实用新型公开了一种覆膜砂输送系统，通过设置一号管道和二号管道，由于覆膜砂的颗粒小、比重大、干燥、摩擦力小，使得覆膜砂的流动性好，进而在运输覆膜砂
