Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a feces collection and discharge device for livestock stalls, and more particularly to a feces collection and discharge device for livestock stalls having a permeable floor.

(Prior art) Livestock barns with floors made of permeable materials such as netting and slats are hygienic because manure falls onto the floor of the barn through holes in the floor and does not accumulate on the floor.
There is a problem in that cold air enters from below, causing problems in raising livestock such as pigs. In addition, since the manure falls from the entire floor, collecting and transporting the manure is time-consuming, and mechanically removing manure is uneconomical, especially in small livestock barns.

(Purpose of the Invention) This invention is an attempt to solve the above-mentioned problems in livestock barns having a floor provided above the floor surface and having a large number of permeable holes. The purpose of the present invention is to provide a livestock barn that prevents this and facilitates collection and discharge of feces.

(Structure of the Invention) The feces collection and discharge device for livestock barns of the present invention, which achieves the above object, is provided above the floor surface of the livestock barn and covers the entire lower surface of the floor in a livestock barn having a floor having a large number of permeable holes. The structure is characterized in that a funnel-shaped excrement receptacle made of a flexible waterproof sheet is fixed to the underside of the floor, and a excrement outlet is provided at the lower end of the excrement receptacle.

It is desirable that the discharge port has a lid that can be opened and closed, and that it is closed except when discharging. Further, if a drainage groove is provided on the floor of the livestock barn so as to be located below the discharge port, the urine and excrement can be dropped directly onto the floor of the livestock barn from the discharge port of the urine receiver and discharged outside the barn.

(Function) The funnel-shaped manure tray that covers the underside of the permeable floor of the livestock pen prevents cold air from entering the floor where the livestock live from under the floor. The excrement that falls from the floor is caught in a excrement receptacle made of a flexible waterproof sheet, and when a certain amount of excrement has accumulated, the outlet is opened and discharged. Since the excrement receptacle is made of a flexible waterproof sheet, if the excrement does not naturally fall to the outlet, the excrement receptacle can be pushed up from below to allow it to fall. Therefore, the slope of the excrement receptacle can be made gentler and the height can be lowered.

(Example) Examples of the present invention will be described in detail below with reference to the drawings.

FIG. 1 shows an example in which the present invention is implemented in a pig stall. The floor 1 of the pig stall is made of net material, and a funnel-shaped excrement receptacle 2 is provided on the bottom surface of the floor 1.

3 is the fence for the pig stall, and 4 is the feeder.

The funnel-shaped excrement receptacle 2 is provided with a discharge port 5 in the center, and is normally closed with a lid or other means, but may be kept open at all times depending on the case.

FIG. 2 shows an example in which such a funnel-shaped excrement receptacle 2 is provided across two adjacent pig stalls A and B.

FIG. 3 is a plan view of a pigsty constructed by connecting a plurality of pig stalls shown in FIG. 2, and FIG. 4 is a sectional view taken along line A-A. Pig stalls A and B are built on a raised floor, and fresh air is supplied from an air supply duct 6 installed in the ceiling. Reference numeral 7 denotes a ventilation fan, which takes in air from under the floor through ventilation holes 8 and discharges odor from the funnel-shaped excrement receptacle 2 to the outside.

Normally, the discharge port 5 is closed, and when a certain amount of excrement has accumulated, a small car is pushed on the lower floor 9 to open the discharge port 5 in order and collect it.

In some cases, a drainage groove 10 such as a U-shaped groove may be provided in the subfloor 9, and the discharge port 5 may be kept open at all times to drain water into a storage tank outside the building, or it may be opened only during cleaning to drain the water for cleaning. It is also possible to run the following.

In addition, if the funnel-shaped excrement receiver 2 is made of a flexible waterproof sheet such as rubber-coated cloth or soft plastic sheet, the angle of the funnel will be small, and if the excrement does not fall naturally to the outlet 5, it can be pushed up from below to fall. This allows the height of the funnel-shaped excrement receptacle to be kept low.

(Effects of the Invention) Since the present invention has the above-mentioned configuration, even in livestock barns using permeable flooring, the bottom surface of the floor is covered with a funnel-shaped excrement receptacle, which prevents cold air from flowing under the floor, thereby allowing livestock to grow. Failures can be prevented.

The excrement outlet is specified, making it easy to collect and discharge feces, and is economical and labor-saving, especially when used in small livestock barns.

If the excrement container is made of a flexible tarpaulin sheet, and the excrement does not naturally fall from the outlet,
It can be pushed up from below and dropped, and the height of the excrement receptacle can be kept low, saving space and reducing costs.

It has remarkable effects such as
