Design and experiment of a self-propelled precision feeding vehicle for caged animals
Aiming at the problems of high cost of individual identification,difficulty in targeted feeding,poor accuracy in feeding amount,and lack of supporting automated feeding equipment for single cage and single feeding animals,a kind of self-propelled precision feeding vehicle for caged animals is designed.The combination of Hall sensor and laser ranging sensor is used to calibrate the position of cages and feeders.The laser ranging sensor is used to automatically determine the cages'position and locate the feeders.The spiral feeding structure is used for feeding amount calibration and precise quantitative feeding.Through the feeding central control system,functions such as caged animal information management,timed feeding,and phased feed intake settings are achieved.The feeding vehicle can automatically determine the dynamic nutritional needs of cage animals during their growth,physiology,and reproduction stages,and complete precise variable feeding.The test results show that under full load,the cage position recognition rate of the feeding vehicle reaches 100％,and the parking positioning deviation is within 3 mm.Taking the preset 50 g,75 g,100 g,and 125 g as the feeding amounts,the maximum deviation between the actual feeding amount of the feeding vehicle and the set feeding amount is 2.32 g,with an average deviation rate of less than 1％,meeting the requirements for precise feeding of single cage and single feeding animals at designated points.
