This invention relates to the field of manure cleaning devices, and discloses a manure cleaning device for dairy farming, including a fixing mechanism, which further includes a connecting column. A limiting rod is slidably connected to the outer wall of the connecting column. A first connecting head is fixedly connected to the front of the limiting rod, and a second connecting head is fixedly connected to the back of the limiting rod. A pressure rod is provided, and the rotating pressure rod squeezes the manure in segments, so that the subsequent scraper applies a pushing force to the manure, causing the manure on both sides and the water inside the manure to converge towards the middle. This prevents the water inside the manure from moving to the bottom of the ditch when the scraper squeezes the solid-liquid mixture of manure. Because a large amount of liquid moves downward, it will increase the viscosity of the manure at the bottom, causing a large amount of manure to remain stuck to the bottom of the ditch after being scraped by the scraper, which is difficult to remove, resulting in a reduction in the effective volume of the manure ditch.
