The invention discloses an automatic feeding packing-course type composting squatting pan. With such materials as saw dust, straw powder, rice hulls, wheat husks and the like as a mixed material, the mixed material is automatically risen in a mixed material cabin by virtue of a spring device at the lower side, the mixed material, along with rotation of a crossed plate shaped rotary toilet bowl, is automatically fed into the squatting pan, and the mixed material sequentially enters a composting cabin in next rotation. The crossed plate shaped rotary toilet bowl turns to the composting cabin after the mixed material is mixed with manure, and a BAW packing-course type composting system, by which composting can be gradually completed from top to bottom, is defined. An isolating system, which is used for isolating the squatting pan, the composting cabin and the mixed material cabin, is defined by a partition board between the mixed material cabin and the composting cabin and the crossed plate shaped rotary toilet bowl, so that odor leakage inwards rooms is prevented; therefore an odor-isolating system is defined. With the application of the squatting pan provided by the invention, a problem of rural water closets which, due to inconvenience in electricity connection, water connection and pipe connection, are difficult in popularization of subsequent sewage treatment can be solved, and a problem on sanitation of existing rural simple toilets can be also improved; and in addition, organic fertilizer can be also generated through ecological toilets, so that resource utilization of manure is achieved.
