Submerged circulating-flow stirrer with good stirring effect

The invention discloses a submerged circulating-flow stirrer with good stirring effect, comprising a worktable, a housing is fixedly connected at the center of the top of the worktable, and a protection box is fixedly connected to the top of the worktable; two sides of the bottom of the worktable are fixedly connected with floating buckets, and a first motor is fixedly connected to the top of theinner wall of the protection box; and a gear is fixedly connected to the output end of the first motor. According to the invention, through combined use of a fixing plate, the housing, the protectionbox, a stirring shaft, the floating buckets, a first stirring blade, a second stirring blade, a fixing block, a bottom plate, a chute, a slider, the first motor, a sliding rod, the gear, a toothed plate and a second motor, the stirring effect is better, the problem that an existing submerged circulating-flow stirrer is not able to conduct stirring in a wider range and causes a poor stirring effectduring usage is solved.
