Constant-temperature mixer for biological and chemical fertilizers

The invention relates to a constant-temperature mixer for biological and chemical fertilizers and belongs to the technical field of fertilizer mixing. The constant-temperature mixer comprises a mixing tank and a workbench; a stirrer is mounted in the mixing tank; the mixing tank is vertically mounted on the workbench; a first support frame and a second support frame are respectively and vertically disposed on the workbench at the left and right sides of the mixing tank; a first feeding chute is mounted in the first support frame; the first feeding chute communicates with the top of the mixing tank through a first feeding pipeline; a second feeding chute is mounted in the second support frame; the second feeding chute communicates with the top of the mixing tank through a second feeding pipeline; a product collecting tank is disposed under a discharge port at the bottom of the mixing tank; the product collecting tank is placed on a placing plate; a heat-insulation jacket layer for temperature regulation is disposed at the periphery of a tank body of the mixing tank; and a first feeding chute conveyor and a second feeding chute conveyor are respectively mounted on the right sides of the first support frame and the second support frame. According to the constant-temperature mixer, before fertilization, fertilizers are mixed conveniently and both time and labor are saved.
