This invention relates to a self-cleaning drinking water device for chicken coops, specifically in the field of water trough cleaning technology. The invention includes a water trough with left and right cleaning troughs connected to its two ends. The highest point of the trough's bottom is located in the middle, and a water inlet pipe is installed on the trough wall at this highest point. The bottom of the trough gradually slopes downwards between this highest point and the two cleaning troughs. Each cleaning trough has a cleaning port with a valve on its bottom surface. A cleaning mechanism is installed inside each trough, and each cleaning mechanism includes at least one cleaning brush that engages with the bottom surface of the cleaning trough. A motor mounting plate is installed above the cleaning brush, and a shaft of a cleaning motor mounted on the mounting plate is connected to a rotating shaft, which is connected to the cleaning brush. This invention adds left and right cleaning troughs at both ends of the water trough, and the bottom of the trough is designed to gradually slope downwards towards both ends. When water is added, sediment in the water trough accumulates in the cleaning troughs at both ends with the water flow, enabling centralized cleaning of impurities.

This utility model relates to the field of poultry farming technology and discloses an automatically cleaning chicken feed trough, including a fixed base. A cleaning component is provided at the middle of the fixed base, and the cleaning component includes a feed trough located at the middle of the fixed base. The feed trough has a water trough and a feed trough arranged sequentially from the inside to the outside. A rotating rod is located at the middle of the upper end of the feed trough. When a first motor is started, the mounting rod drives a cleaning plate to rotate circumferentially along the inner walls of the water trough and feed trough. Because the cleaning plate is in contact with the inner walls of the water trough and feed trough, it can clean these surfaces. When the cleaning plate passes the upper end of the discharge port, residual feed and debris in the feed trough fall out through the discharge port, thus automatically cleaning the feed trough without manual intervention, reducing worker workload and increasing cleaning efficiency.
