The plow spindle 2 is horizontally arranged in the horizontal cylinder 1. The cover plate 8 is laterally movably arranged at the open end of the horizontal cylinder 1. The cover plate 8 is provided with screws 9 that connect to the horizontal cylinder 1. The structure is stable, which improves the stability of the castable premixing process.

[0017] The other end of the horizontal cylinder 1 is closed and equipped with a reducer 14 for driving the plow blade spindle 2 to rotate. In this embodiment, the input end of the reducer 14 is equipped with a first motor 15 to realize the rotation of the plow blade spindle 2.

[0018] The cover plate 8 is provided with a bearing seat 16, and a support shaft 7 pointing to the plow blade main shaft 2 is provided in the bearing seat 16. A coupling 6 is detachably provided between the support shaft 7 and the plow blade main shaft 2, which improves the stability of the rotation process of the plow blade main shaft 2 without affecting the separation of the cover plate 8 from the horizontal cylinder 1, which is conducive to the disassembly and maintenance of the cover plate 8.

[0019] A stirring rod 3 is spaced along the plow shaft 2, and the plow blade 4 is located at the end of the stirring rod 3. The rotation of the stirring rod 3 and the plow blade 4, driven by the plow shaft 2, premixes the refractory material. A feed port 5 is provided at the top of the horizontal cylinder 1, through which the refractory material can be poured into the horizontal cylinder 1. A discharge port 11 is provided at the bottom of the horizontal cylinder 1, and a discharge valve can be installed at the discharge port 11.
