| Adjustment with the pattern of agricultural production for the past years, the animal husbandry increases year by year in Xinjiang province, and the milk cow already becomes the important part of animal husbandry. With the fact that milk cow expands increasingly, the tradition manpower feeds has not been adapt to development , it require that being going to develop to modernize , scientism , and technology is advanced , the function is good. And but, the fodder at present commonly is the manpower feeds, it has strong labor, the low efficacy, and to a certain extent, the effect feeding affects with the artificial factor effect, therefore, milk cow has not feasible feed, and it has blocked the development of milk. And at present, milk cow fodder hey machinery adopts commonly to volume-weigh, the accuracy being really not ideal.Firstly,The article summarizes the development of weighing technology, current situation at home and abroad, the application of the milk cow feed. It suggests that the milk cow fodder has Batch-weigh with frequency conversion, and weighing accuracy having assumed studying, aiming at raising accuracy.Secondly, based on the relativity analysis between measuring mass and time and rate and fill coefficient. And it has ascertained that basic structure frame of milk cow fodder, it chooses main component (such as Screw conveyer, weighing appearance) according to the request of milk cow fodder feeds. And it has provided solid experiment platform for the studying.Thirdly, studying that weigh system of milk cow fodder, such as composition of weighing system, selection for weighing sensor, parameter of weighing appearance, and having brought corresponding solving for the accuracy factor(such as sensor error, reinforced error ).Finally, it reached that under the same rotation rate, midair material amounts keeps invariant through analysis, and fill coefficient may increase for decreasing feed time, it has provided the theory basis for by analysis.Ultimately, the optimization improvement on key organization improves according to test, and the Weighing precision reaches(Measuring range)±5%. |
