Automatic obstacle crossing type snow pushing device
The invention discloses an automatic obstacle crossing type snow pushing device which is characterized by comprising a snow pushing plate, the middle of the snow pushing plate is hinged to a hinge frame, the upper end or the lower end of the snow pushing plate is hinged to one end of an oil cylinder, and the other end of the oil cylinder is hinged to the hinge frame; the oil cylinder comprises an oil port, the oil port is connected with an energy accumulator and a working hydraulic system to form an energy accumulator hydraulic system serving as an air spring, and the energy accumulator hydraulic system is a closed system; when the snow pushing plate is in a normal snow pushing state, the telescopic end of the oil cylinder is in an extension state; when the snow pushing plate touches an obstacle and reaches overload, the telescopic end of the oil cylinder contracts, so that the snow pushing plate overturns and crosses the obstacle. According to the invention, the snow removing and automatic obstacle-crossing functions are reserved, heavy-load snow removing work with large resistance such as ice and snow can be shoveled, and the obstacle-crossing effect is better due to the fact that the overturning stroke is increased. The automatic obstacle crossing type snow pushing device is used for automatic obstacle-crossing snow pushing operation and can be used in cooperation with a wheel loader or an automobile or other power vehicles.
本发明公开了一种自动越障式推雪装置，其特征在于，包括推雪板，推雪板的中间位置与铰接架铰接，推雪板的上端或下端与油缸的一端铰接，油缸的另一端与铰接架铰接；油缸包括油口，油口与蓄能器及工作液压系统连接，形成作为气弹簧的蓄能器液压系统，蓄能器液压系统为密闭系统；当推雪板处于正常推雪状态时，油缸的伸缩端处于伸长状态；当推雪板碰到障碍物，达到超载时，油缸的伸缩端收缩，使得推雪板翻转越过障碍物。本发明除保留除雪和自动越障式功能，还可以铲冰雪等阻力较大的重载除雪作业，由于加大了翻转行程，越障效果更好。本发明用于自动越障式推雪作业，可与轮式装载机或汽车等动力车辆配套使用。
