The blanking end of the excrement conveying belt 1 is far away from the grid cage 2, the sewage receiving tank 3 can be arranged outside the culture area, and the chance that the sewage receiving tank 3 volatilizes gas to pollute the culture area is greatly reduced. The transmission direction of the excrement conveying belt 1 is parallel to the straight line formed by the grid cages 2, so that the caliber of the sewage receiving groove 3 can be reduced as much as possible, and gas volatilization is reduced. This embodiment can accomplish to connect dirty groove to collect filth unified treatment, and whole process manual work degree of participation is low, is favorable to reducing the chance that pollutant and people removed, is favorable to ensureing the health of breeder, experimental animals facility maintainer and experimenter. However, there are some disadvantages that the faecal transfer belt 1 passes under each cage 2, and the animals in the downstream row of cages 2 always see and smell the faecal matter of the upstream animal, and most of the animals are identified as belonging to the faecal matter, which easily causes discomfort for the downstream animals, and the following improvements are proposed.

The automatic excrement cleaning equipment for the cage further comprises a support 4 for lifting the grid cage 2, an openable excrement temporary storage disc 41 is arranged on the support 4, the excrement temporary storage disc 41 is located between the grid cage 2 and the excrement conveying belt 1, and a fan-shaped spray head 42 for cleaning the excrement temporary storage disc 41 is arranged on the support 4. The fan-shaped spray head 42 is washed by a water curtain, so that the water consumption is low and the washing pressure is high. Preferably, partitions are provided between adjacent mesh cages 2 for reducing the passage of odors, the partitions being mounted on the frame 4. When cleaning up excrement, only one excrement buffer disk 41 of the mesh cage 2 is opened at a time, and when opened, the fan-shaped spray head 42 washes the excrement buffer disk 41. The flushing action can be realized by a position switch which is triggered to open the fan-shaped spray head 42 when the openable excrement temporary storage tray 41 is opened to a certain extent, and to close the fan-shaped spray head 42 when the excrement temporary storage tray 41 is closed to a certain extent.
