Description

Technical Field

[0001] The invention belongs to the technical field of livestock and poultry excrement cleaning, and in particular relates to vacuum suction excrement cleaning equipment. Background Art

[0002] Vacuum manure cleaning equipment is a commonly used animal manure treatment device in livestock and poultry farms. It uses the working principle of a vacuum pump to extract the air in the storage tank to form a low-pressure area, thereby sucking feces, debris and sewage from septic tanks, sewage ditches, sewers and other places into the storage tank for centralized treatment.

[0003] The existing vacuum fecal suction truck puts the fecal suction pipe into the manure pit, and uses the vacuum pump to extract the air in the tank to form negative pressure, and then pumps feces and sewage into the tank. Because feces are easily precipitated in the manure pit to form upper and lower layers, it is impossible to mix the upper liquid and the lower solid to extract. Directly extracting the upper part can only extract liquid waste, causing solid waste to settle down; if the solid waste in the lower part is directly extracted, it is easy to clog the fecal suction pipe, affecting the normal feces cleaning work, and the use effect is not good.
