Technical Field

The invention belongs to the technical field of intelligent pig raising, and particularly relates to a water drinking system for fattening pigs.

Background

In the intelligent pig raising process, complete system information construction is needed to ensure the scientificity and intelligence of pig raising from pig seed selection, live pig feeding, disease epidemic prevention, weight monitoring, marketing management and information tracing, and the centralized processing and analysis of the data are the key and trend of intelligent pig raising.

Based on the development of information technology and the application of the information technology in a pig farm, currently, the critical data of the day age, the weight, the body size, the feed intake, the water intake and the like of the pigs in the pig farm in the breeding process can be basically obtained in real time. For example: the method is characterized in that an RFID electronic tag is worn on a pig, one-to-one information editing (including pig species, weight, vaccine epidemic prevention conditions and the like) is carried out on the pig and the pig according to a unique ID code of the RFID electronic tag, meanwhile, an RFID reader is installed in a pig passage, a pig feeding groove, a pig weighing table and the like, when the pig enters the identification range of the RFID reader, the reader can automatically identify relevant information (such as weight, eating, drinking, vaccine, sick condition medicine feeding conditions and the like) of the pig, the acquired information is automatically uploaded to a data center, and a manager checks the condition of the pig through an operating system.

However, in the process of conventional pig raising or intelligent pig raising, problems in a plurality of subdivided fields still remain to be solved, wherein the most important problem is that the drinking bowl of the fattening pig is difficult to clean. Although the pig water bowl has the advantages of water conservation, safe use and the like, the defects are very obvious: the pigs can bring the feed attached to the mouth into the drinking bowl only in the process of drinking water, so that dirt can be accumulated in the using process, and the pigs are troublesome to clean; taking a fattening pig barn as an example, on average, dirt accumulation in drinking bowls occurs every two days, even dirt appears on the bowl walls, and therefore, workers need to regularly perform water spraying cleaning and brushing cleaning, and one working worker needs to clean one drinking bowl at least for two minutes, which wastes time and labor.
