Abstract: An automatic sand abrasion device includes a shell, an integrated framework, a sand falling mechanism, a sand transport mechanism, a sand falling channel, a sample working frame and a circuit control cabinet, where the device adopts the transport belt and the second speed reduction motor to realize transportation of sand, and realizes that the weighed sand falls into the bottom of the abrasion device through the first speed reduction motor and the automatic weighing machine. The whole process can be automatically operated while parameters such as the operation time and the weight of abrasion sand are set, so that the detection efficiency for the abrasion resistance can be improved, and the labor cost is greatly reduced. The device is firm in structure and stable and reliable in work and improves the accuracy and efficiency of an experiment.
