目前，装载机操纵机构大多采用两个操纵手柄分别控制动臂的升降和铲斗的翻转。在操纵其中一个手柄的同时不能进行另一个手柄的操纵，即在动臂的升降过程中不能同时实现铲斗的翻转，尤其在配合铲装时，操作者必须频繁更换操纵手柄，操作不便，劳动强度较大。为此我们开发了一种? At present, most of the loader control mechanisms use two control handles to control the boom lift and bucket overturning, respectively. When one of the handles is manipulated, the other handle can not be manipulated, ie, the bucket can not be turned over simultaneously during the lifting of the boom. In particular, when the shovel assembly is used, the operator must frequently change the handle to make the operation inconvenient and laborious Greater strength. For this we have developed a?
