摘要:

为解决小麦收获机械中存在的损失、损伤、含杂率高、断裂及粘附问题,对小麦进行摩擦和拉伸试验。以“济麦20号”为试验对象,含水率36.16%为试验边界条件,采用PM-8188谷物水分测试仪测试含水率、机械式静摩擦试验台测试静摩擦因数、QT-1186电子试验机测试拉伸特性。结果表明:橡胶材料与小麦各部分的静摩擦因数较大,仿生拨禾机构和仿生脱粒机构采用橡胶材料能够增加静摩擦力;小麦各部分的抗拉能力从下向上逐渐减小,采用水平旋转揉搓脱粒工艺、仿生切割摘穗部件能够提高脱净率、降低含杂率、减少额外功耗。

Abstract:

To overcome the problems in wheat harvesting machine such as loss, damage, high impurity rate, fracture and adhesion, the friction and tensile properties of wheat were studied by experiments. The 'Jinan wheat 20' was used as subject. The moisture content of the wheat was 36.16% measured with a PM-8188 grain moisture tester. The static friction coefficient was measured on a mechanical static friction test bench. The tensile curve was obtained using a QT-1186 electronic testing machine. Results show that the static friction between rubber and wheat is higher than other materials. So the bionic reel and threshing mechanism made of rubber could increase the static friction force. The tensile strength gradually increases from the bottom to top. Using horizontal rotation rub threshing process and bionic cutting parts could improve the threshing performance and reduce the impurity rate with lower power consumption.
