[0087] The motor control module 613, the infrared emitter 71 and the infrared receiver 72 are electrically connected to an external control system. When excrement falls on the excrement adsorption roll 5, the emitted infrared rays 711 are blocked from being received, and the signal that cannot be received is transmitted to the control system. When the control system detects that more excrement has fallen, the driving motor 611 is started to operate through the motor control module, so that the excrement is collected into the excrement collecting tank 4, and automatic cleaning of the excrement is realized.

[0088] Referring to Figure 4 The excrement separating assembly 12 is provided with a first rotating roller 121 and a second rotating roller 122 arranged in parallel with the second roller 632. A partition plate is arranged vertically to the conveying direction at the bottom of the excrement collecting tank body, and the partition plate is connected to the inner side walls of the excrement collecting tank body on both sides, so as to divide the excrement collecting tank body into an excrement collecting cavity and a roll collecting cavity. The first rotating roller 121 is rotatably arranged in the excrement collecting cavity above the corresponding partition plate, and the second rotating roller 122 is rotatably arranged in the roll collecting cavity below the corresponding first rotating roller 121.

When the roll passes by the first rotating roller 121, the excrement on the surface of the roll falls into the excrement collecting cavity under the action of gravity, and the roll is conveyed by the second rotating roller 122 into the roll collecting cavity. The excrement is separated out conveniently, and the subsequent harmless treatment of the excrement adsorption roll is facilitated.

[0089] The excrement adsorption roll 5 comprises, from top to bottom, a non-woven fabric layer 51, a liquid absorption layer 52, a support layer 53 and a leakage prevention layer 54.

[0090] The non-woven fabric layer 51 is made of non-woven fabric, which is used to carry and adsorb excrement and protect the liquid absorption layer 52. The liquid absorption layer 52 is made of superabsorbent polymer (mainly made of starch and acrylic acid salt), which is used to absorb water in the excrement. The support layer 53 is in a grid shape and mainly composed of a mesh line made of metal or nylon, which is used to carry the non-woven fabric layer 51 and the liquid absorption layer 52. The leakage prevention layer 54 is made of a water-impermeable material, such as a PP or PE film, which is used to prevent liquid from leaking out of the excrement adsorption roll 5.

[0091] In a specific embodiment, the chain slot holes 531 on both sides of the excrement adsorption roll 5 penetrate the non-woven fabric layer 51, the liquid absorption layer 52, the support layer 53 and the leakage prevention layer 54. In another specific embodiment, the non-woven fabric layer 51, the liquid absorption layer 52 and the leakage prevention layer 54 have the same width, and the support layer 53 has a width greater than that of the non-woven fabric layer 51, so that the edges on both sides of the support layer 53 exceed the non-woven fabric layer 51. The edges of the support layer 53 on both sides of the non-woven fabric are provided with chain slot holes 531 for driving the entire excrement adsorption roll 5 to move by the chain wheel 633. The non-woven fabric layer 51, the liquid absorption layer 52, the support layer 53 and the leakage prevention layer 54 can be sewn, hot-melted or ultrasonically welded together to ensure that the layers are not loose.

Two groups of spray heads 92 are connected to the two ends of the main water pipe 91, respectively.

[0096] In this embodiment, the spray head 92 includes a water spraying pipe arranged perpendicularly to the main water pipe 91. A plurality of water spraying holes are formed on both sides of the water spraying pipe at intervals. The water spraying holes can spray water flow to the inner wall of the excrement collecting bucket 8 and the center of the excrement collecting bucket 8, so as to clean the excrement collecting bucket 8 comprehensively.

[0097] When the animals do not need to be dry-raised, the excrement adsorption roll 5 is not needed to be installed, and the animal excrement directly falls into the excrement collecting bucket 8. Water is sprayed into the excrement collecting bucket 8 to make the excrement discharged by the sewage discharge pipe.
