Abstract: Aiming at the problems of large investment in the pig liquid feeding system based on pipeline transportation, and high requirements for the quality of users, also equipment failures requiring professional and technical personnel to repair, a kind of intelligent pig liquid feeding vehicle is designed. Zigbee communication is used between the feeding vehicle and the mixing station, and network operation is used to realize automatic cruise control of loading, transportation and feeding; the feeding vehicle adopts magnetic nails and magnetic control switches to realize automatic address recognition, positioning and precise parking. Feeding by screw pump realizes precise feeding. The test results of the prototype show that the feeding vehicle can be accurately stopped at the target site (position deviation ≤1 cm) by decelerating in advance when the feeder is fully loaded. Taking the preset 3、 5、 10 kg as the feeding amount, the actual feeding amount error of the feeding vehicle can be controlled within 2.5%. Compared with the pipeline liquid pig feeding system, the automatic pig liquid feeding system based on the intelligent feeding vehicle has the advantages of less investment and high equipment operation reliability. The promotion of technology provides technical support.

摘要： 针对基于管道输送的生猪液态饲喂系统投资大、对使用人员素质要求高、设备故障需要专业技术人员进行维修等问题，设计一种生猪液态饲料智能喂料车。喂料车与搅拌站之间采用Zigbee通讯，组网运行，实现装料、运送及投料的自动巡航控制；喂料车采用磁钉、磁控开关实现自动认址、定位及精准停车；采用螺杆泵送料，实现精准饲喂。样机试验结果表明，喂料车满载情况下通过提前减速可以实现在目标站点精准停车(位置偏差≤1 cm)；以预设的3、5、10 kg为投喂量，喂料车实际投喂量误差可以控制在2.5%以内。与管道式生猪液态饲喂系统相比，基于智能喂料车的生猪液态饲料自动饲喂系统具有投资少、设备运行可靠性高等优点，可广泛适用于中小规模养猪场，对生猪液态饲喂技术的推广提供技术支撑
