Snow sweeper and hydraulic control system thereof
The invention discloses a snow sweeper and a hydraulic control system thereof. The hydraulic control system comprises an oil pump assembly, a first oil supply way, a second oil supply way and a control unit. The oil pump assembly comprises a first hydraulic pump and a second hydraulic pump which are coaxially connected in series. The first hydraulic pump supplies oil to the rolling brush motor through a first oil supply way, and a distribution valve is arranged on the first oil supply way; the second hydraulic pump is arranged on the second oil supply oil way, a combined oil way is arranged on a connecting oil way between the first oil supply oil way and the second oil supply oil way, and a flow collecting valve is arranged on the combined oil way. The control unit is electrically connected with the distribution valve and the flow collecting valve and is configured to obtain the load working condition of the rolling brush motor; and the distribution valve or the flow collecting valve is controlled to act according to the load working condition of the rolling brush motor, so that the first oil supply oil way or the combined oil way supplies oil to the rolling brush motor. Through the switching action of the distribution valve and the flow collecting valve, different load working condition requirements of the rolling brush motor can be met, and full utilization of energy is achieved.
本申请公开了一种除雪车及其液压控制系统，液压控制系统包括油泵组件、第一供油油路、第二供油油路和控制单元；油泵组件包括同轴串联的第一液压泵和第二液压泵；第一液压泵通过第一供油油路对滚刷马达供油，第一供油油路上设有分配阀；第二液压泵设于第二供油油路上，第一供油油路和第二供油油路之间的连接油路上设有合并油路，合并油路上设有合流阀；控制单元与分配阀和合流阀均电连接并被配置为：获取滚刷马达的负载工况；根据滚刷马达的负载工况控制分配阀或合流阀动作，以使第一供油油路或者合并油路对滚刷马达供油。本申请通过分配阀和合流阀的切换动作，能够满足滚刷马达的不同负载工况需求，实现能源的充分利用。
