[0016] Further, a cover plate is connected to the hand hole.

[0017] Further, the two sides of the bottom plate are connected to the two sides of the top plate through side plates, respectively.

[0018] The beneficial effects of the present application are as follows:

[0019] 1. The present application sets the feeding port above the bottom plate, so that the material falls on the bottom plate to slow down the falling speed, and the material is dispersed and rolled under the effect of the spoiler of the bottom plate, avoiding the material entering the furnace in the form of strands or columns.

[0020] 2. The present application further disperses the material by arranging a spoiler on the bottom plate, and the bottom plate is trapezoidal with a wider lower end, which is more conducive to the dispersion of the material.
