Intelligent pig feeding device and method

Abstract

Disclosed is an intelligent pig feeding device. A feeding station is arranged at the position of the edge of a pigsty, a station inlet door is arranged at one end of the feeding station, a station outlet door is arranged at the other end of the feeding station, an ear tag recognizer which can recognize electronic ear tags in an inducting mode is arranged outside the station inlet door and a first photo-electric inductor used for inducting whether a pig passes through or not is arranged in the feeding station. A middle isolation door is further arranged between the station outlet door and a feeding point, the middle isolation door divides the feeding station into a feeding area and a transition area and a second photo-electric inductor used for inducting whether a pig passes through or not is arranged in the transition area; idler wheels are arranged at the bottom of a trough, the trough is further provided with a circulation chain in a tying mode, the circulation chain is driven by a motor to rotate circularly, and the trough moves circularly under the driving of the circulation chain; a weighing sensor is further arranged at the feeding point. The invention further provides an intelligent pig feeding method. By means of the intelligent pig feeding device and method, the situation that pigs occupy the feeding station unreasonably can be avoided and the phenomenon that subsequent pigs are over fed due to the fact that a prior pig does not eat up feed is also avoided.

Description

technical field [0001] The invention belongs to the technical field of animal husbandry, and in particular relates to an intelligent pig feeding device and an intelligent pig feeding method. Background technique [0002] The most traditional pig farm adopts the way of limited stalls for feeding: each pig is confined in a limited pen, the width of the limited pen is 60-65CM, and there is a feed trough in front of the limited pen. The size of the stall can only accommodate one pig, and the pig cannot turn around in the stall; the feed trough is just placed in front of the pig, and feed is regularly put into the feed trough to realize feeding. The advantage of the above-mentioned feeding method is that there will be no snatching of food among the pigs. However, the disadvantages of the above-mentioned feeding methods are also obvious: the pigs are enclosed in a narrow space, unable to walk, unable to exercise, poor in physique, low in disease resistance, and low in fertility. ...

Problems solved by technology

However, this captive breeding method also has shortcomings: when feeding, there will be a problem of food grabbing among the pigs, and the actual food intake of each pig will be uneven and unreasonable. The thin pigs often fail to grab food and become thinner. Fat and fat pigs often eat too much and cause waste of feed

[0005] However, the applicant has found in practice that there are still problems to be improved in the existing smart feeding system for pig farms: after the pigs enter the feeding station, they are often greedy, so after the feed in the feed trough is eaten up, Still staying by the feed trough for a long time and not walking away, this will cause unreasonable occupation of the feeding station for a long time, making it impossible for other pigs to enter the feeding station for a long time

[0006] In addition, in the existing smart feeding system for pig farms, if the previous pig has a poor appetite and does not completely eat up all the feed in the feed trough, the remaining feed will be reserved for the next pig, and the latter pig is feeding Failure to take this factor into account at the time can lead to overfeeding of the next pig and sometimes even accumulation of surplus from multiple pigs
