Problems solved by technology

The pig toilet is equipped with a grid frame above the ground, which does not conform to the physiological habits of pigs. Pigs must step into the grid frame before going to the toilet, and the collection tank is still located inside the pig house. It is only cleaned by regular suction. If the cleaning is not timely, it will also cause the odor to spread, and the space of the collection tank is too small, which is not conducive to storing a large amount of feces

Embodiment 1

[0031] Such as figure 1 and figure 2 As shown, there is an excretion area 2 in the lower right corner of a column 1 of the piggery in the present embodiment, i.e. a lavatory. The two sides of the opening of the area 2 are hinged with iron rails 23 to realize the sealing of the excretion area 2 .

[0032] In order to detect whether pigs exist in the excretion area 2 at any time, a sensor is installed on the wall opposite to the iron fence 23, such as an infrared sensor 4, and an automatic door lock is installed on the iron fence 23, and the infrared sensor 4 can send control to the automatic door lock. Signal. When a pig enters the excretion area 2, the automatic door lock receives the control signal sent by the infrared sensor 4, so the automatic door lock is locked in one direction in the direction that the iron fence 23 enters the toilet, and other pigs cannot enter the excretion area 2 at the same time. Pigs in the excretion area 2 can easily get out of the toilet. The...

Embodiment 2

[0040] This embodiment discloses another piggery with lavatories, the part on the ground of the excretion area is the same as that of Embodiment 1, the difference is that the structure of the cesspit 5 is different from that of Embodiment 1, and the cesspit 5 of the present embodiment can be Realize solid-liquid separation of feces.

[0041] Such as Figure 5 As shown, the cesspit 5 uses a slope with a slope of 7-10% as the slope 9, which can ensure that most of the pig manure can slide smoothly into the separation chamber 10 outside the pig house that can realize solid-liquid separation.

[0042] In order to realize the solid-liquid separation of feces, the bottom of the separation chamber 10 is a slope 101 with a slope of 1.5%. The slope 101 is connected to the end of the slope 9. The urine will continue to flow downward on the slope 101 and pass through The filtration of the filter screen 102 enters in the defecation pipe 103 . The feces will not continue to slide down on...

Abstract

The invention discloses a pigsty with toilets. The pigsty is separated into a plurality of regions; a corner of each region is an excretion area; each excretion area comprises a floor and a wall; each wall is provided with an inlet; each floor is a slatted floor made of stainless steel; a manure pit is formed below each slatted floor; and a manure discharge pipeline communicated with each manure pit is arranged. Each excretion area is arranged in each region of the pigsty, and an aim of making pigs excrete at fixed points through training is fulfilled. The pigs excrete in the toilets in the pigsty, and a small quantity of excrement which is remained in a solid area of each floor induces the pigs to excrete in the toilets. The manure in the toilets of the pigsty enters the manure pit through leaks of the floors where the excretion areas are positioned, and is timely discharged out of the pigsty. The toilets can provide an undisturbed excretion environment for the pigs, and also can improve the air quality in the pigsty.

Description

technical field [0001] The invention relates to a pig house, in particular to a pig house with a toilet. Background technique [0002] With the continuous increase of pig breeding density, the environmental sanitation problems of pig houses have become increasingly prominent, and odor pollution has gradually become an important factor affecting the internal environmental quality of pig houses. The odor in the pig house environment mainly comes from the pig manure and urine produced by pig excretion. Pig manure and urine contain a lot of nitrogen and phosphorus. Under anaerobic conditions, it will be decomposed into NH, which is very harmful to human and animal health. 3 、H 2 S, CH 4 and other harmful gases. If live pigs live in this kind of pig house environment for a long time, it will irritate the upper respiratory tract mucosa, and it is very easy to infect or trigger respiratory diseases, such as swine asthma, infectious pleuropneumonia, swine pneumonia, etc. Dirty p...
