摘要
为了寻求抛撒不同羊食用物料最佳效果时撒料车的最佳工作参数和结构参数匹配,设计了固定式羊用撒料试验台。该试验台可灵活调节影响撒料效果的工作参数和结构参数,可模拟撒料车行走撒料的功能。本文对该试验台机械结构和工作原理进行了介绍,对关键机构双向投料搅龙进行设计,确定其最大转速为150r/min,对刮板输送机装置进行设计,确定其具有平移整体物料作用。以玉米青贮和玉米粉混合物为试验物料,以投料均匀度和投料量为试验指标,以刮板输送机线速度A、挡料辊转速B、双向搅龙转速C、拨叉长度D为试验因素设计四因素三水平两指标正交试验。试验结果表明:投料量影响因素显著程度顺序为A>B>C>D;投料均匀度影响因素显著程度顺序为A>C>D>B;最优参数匹配组合A为0.1m/s,B为150r/min,C为15r/min,D为1 3 0 mm,对应的投料量为7.1 3 kg/s,投料均匀度为9 2.2 1%。该撒料试验台的性能参数满足设计要求。
In order to find the optimal working parameters and structural parameters matching of spilling feed car when throwing different food materials for sheep, the fixed type spilling feed test-bed for feeding sheep that can adjust flexibly the working parameters and structural parameters and simulate the function of feeding car walking and spilling feed was designed. This paper introduced the mechanical structure and working principle of test-bed , and designed the bidirec- tional feeding auger that maximum speed was 150r/rain, and designed the Scraper conveyor equipment that can translate the integrated material, and designed the four factors and were corn silage and corn flour mixture, test indexes were three levels orthogonal test with two indexes that test materials spilling feed uniformity and spilling feed amount, test factors were the line speed of scraper conveyor A, speed of feed roller B, speed of bidirectional auger C, length of fork-lever D. The test results showed that the significant degree of spilling feed amount influencing factors was A〉B〉C〉D;the sig- nificant degree of spilling feed uniformity influencing factors was A〉C〉D〉B;the optimal parameter matching combination were A 0. lm/s , B 150r/min, C 15r/min and D 130mm, the corresponding spilling feed amount was 7.13kg/s and corresponding spilling feed uniformity was 92.21%. The test results show that the performance parameters of the test- bed meet the design requirements.
