Hydrostatic four-wheel-drive walking system and silage harvester

The utility model provides a hydrostatic four-wheel drive walking system and a silage maize harvester, and relates to the field of agricultural machinery. The linear speed of each driving wheel can be detected through a speed sensor, namely, the first wheel set and the second wheel set can be detected to be in a running state or a slipping state; therefore, when the first wheel set or the second wheel set is in a slipping state, the adjusting valve set arranged between the oil conveying piece and the front axle mechanism can correspondingly adjust the control position where the adjusting valve set is located, then the flow distribution value of the whole walking system is adjusted to prevent flow loss, the working pressure of the walking system can be rapidly established, and the working efficiency of the walking system is improved. Therefore, the driving wheel can get out of trouble in time. 本实用新型提供了一种静液压四驱行走系统及青贮机，涉及农业机械领域。通过速度传感器能够分别检测到各个驱动轮的线速度，即能够检测第一轮组以及第二轮组处于行驶状态或打滑状态；从而当第一轮组或第二轮组处于打滑状态时，设置于输油件与前桥机构之间的
