The invention discloses an automatic dust remover system. The automatic dust remover system comprises N dust remover units, a dust removal inner pipe, a dust removal outer pipe, N first drive mechanism, a second drive mechanism and a controller. The bottom of each dust remover unit is connected with an air supply pipe. Each air supply pipe comprises an air supply inner pipe and an air supply outer pipe, wherein the lower end of each air supply inner pipe extends into the outside of the lower end of the corresponding air supply outer pipe, the lower end of each air supply outer pipe is provided with a first rubber sleeve, and the outer wall face of each first rubber sleeve is a reversed-circular-truncated-cone-shaped surface. The dust removal inner pipe is evenly provided with N first connectors. Each second rubber sleeve comprises a cylindrical body portion and an annular thin wall portion. The dust removal outer pipe is evenly provided with N second connectors. The controller controls the dust removal inner pipe to slide for a certain distance along the dust removal outer pipe so that M first connectors and M second connectors can be mutually aligned, and the air supply inner pipes of M air supply pipes are inserted into the M first connectors, wherein M is larger than or equal 1 and smaller than or equal to N. According to the automatic dust remover system, the number of the dust remover units can be flexibly adjusted according to needs.
