Further, two opposite side walls of the septic tank 12 parallel to the length direction of the collector 01 are respectively provided with a flow guide member 15; the flow guide member 15 comprises a first inclined surface 151 and a second inclined surface 152, the first inclined surface 151 inclines upwards from the inside of the manure storage tank 12 to the side wall, the second inclined surface 152 inclines downwards from the inside of the manure storage tank 12 to the side wall, and the first inclined surface 151 is positioned above the second inclined surface 152.
Specifically, referring to fig. 4 and 5, a flow guide member 15 is fixedly mounted below a gap between two sides of the collector 01 in the width direction and the side wall of the septic tank 12, and a first inclined surface 151 and a second inclined surface 152 on the flow guide member 15 extend along the length direction of the collector 01; the first inclined plane 151 is used for guiding the downward sliding process of the wastes, so that most of the wastes can fall to the middle part of the septic tank 12, and the wastes are prevented from being retained on the side wall of the septic tank 12 and being excessively accumulated on the two sides of the septic tank 12; the second slope 152 guides the rising process of the gas in the manure pit 12 to flow toward the upper middle position, so that the gas is easily collected in the collector 01, and the gas is prevented from entering the livestock house 10 from the gap between the collector 01 and the side wall. The horizontal distance from the connecting line of the first inclined surface 151 and the second inclined surface 152 to the side wall of the manure storage tank 12 is more than 5cm, so that articles falling from the gap between the collector 01 and the side wall of the manure storage tank 12 can fall on the first inclined surface 151 and then slide down to the middle position of the manure storage tank 12 under the guiding action of the first inclined surface 151, and the contact surface of the second inclined surface 152 for guiding the rising gas in the manure storage tank 12 has enough length to allow the gas to flow to the middle position and enter the collector 01.
Further, the vertical distance between the upper edge of the flow guide member 15 and the lower edge of the collector 01 is more than or equal to 5 cm. Specifically, the diversion member 15 is positioned below the collector 01, and the vertical distance between the top edge of the first inclined plane 151 and the bottom edge of the first plate 011 and the vertical distance between the top edge of the second inclined plane 151 and the bottom edge of the second plate 012 are both more than or equal to 5cm, so that the waste can conveniently fall from the gap between the collector 01 and the side wall of the septic tank 12, and after reaching a certain speed under the action of gravity, the waste can contact the first inclined plane 151 and fall to the middle part of the septic tank 12 under the guiding action of the first inclined plane 151; in embodiments of the invention, the vertical distance of the upper edge of the flow guide 15 from the lower edge of the collector 01 may be 5cm, 6cm or 7 cm.
Further, an intake fan 16 is provided on the top of the poultry house 10. Under the action of the negative pressure exhaust fan 04, air in the livestock and poultry house 10 is discharged to the outside through the air collecting pipe 03, the air in the livestock and poultry house 10 is reduced, relative negative pressure is formed relative to the outside, the intake fan 16 is driven to work under the action of the negative pressure, the external air is sucked into the livestock and poultry house 10, and the air pressure of the livestock and poultry house 10 is maintained to be stable.
Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; while the invention has been described in detail and with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present invention.
