Shovel frame lifting hydraulic structure of ice surface snow removal land leveler and land leveler
The invention belongs to the technical field of snow removing equipment, and particularly relates to a shovel frame lifting hydraulic structure of an ice surface snow removing land leveler and the land leveler. The shovel frame lifting hydraulic structure comprises an oil tank, a hydraulic pump, an overflow valve, an electromagnetic reversing valve and a hydraulic rod, and the oil tank, the hydraulic pump, the overflow valve, the electromagnetic reversing valve and the hydraulic rod are communicated through an oil pipe I; the oil tank is connected with an electromagnetic control valve through two second oil pipes, one of the second oil pipes is communicated with the hydraulic pump through the electromagnetic control valve, and before the hydraulic system is started, warm hydraulic oil is used for continuous circulation, so that the temperature of equipment and pipelines is slowly increased; therefore, when the hydraulic system is started, the equipment is in a warm state, the situation that the equipment cannot be started due to low temperature is avoided, the condition that the equipment is started frequently for several times to increase the oil temperature to reduce the start-stop frequency is avoided, the loss of the whole equipment is further reduced, and the service life is prolonged.
本发明属于清雪设备技术领域，尤其涉及一种冰面除雪平地机的铲架升降液压结构及平地机，包括油箱、液压泵、溢流阀、电磁换向阀以及液压杆，所述油箱、液压泵、溢流阀、电磁换向阀以及液压杆之间通过油管一连通，所述油箱通过两个油管二连接有电磁控制阀，其中一个所述油管二通过电磁控制阀和液压泵之间连通，在液压系统启动前，利用温热的液压油进行不断的循环，从而让设备、管道的温度慢慢上升，这样在启动液压系统的时候设备处于温热状态，就不会出现温度低设备无法启动的情况，也不需要频繁多启动几次来升高油温，来降低启停频率，进一步降低整个设备的损耗，延长使用寿命。
