Description

Lubricating oil tank for excavator chain Technical Field The utility model relates to the technical field of lubricating oil for excavator chains, in particular to a lubricating oil tank for excavator chains. Background The excavator head replacement device is generally provided with a transmission member such as a chain, and the transmission member such as the chain is inevitably worn and quickly worn with the increase of the use times, so that an excavator chain lubricating system is generally arranged on an excavator. The existing excavator chain lubricating system usually discharges hydraulic oil in some hydraulic systems through an oil way to lubricate the chain, however, the hydraulic oil of the hydraulic system is wasted in such a way, so that the chain lubricating cost is too high. Another possible way is to set up the lubrication tank that is loaded with some lubricating oil in the excavator head change device, discharge some lubricating oil in the lubrication tank through the oil circuit and lubricate the chain, this kind of mode need not extravagant hydraulic system's hydraulic oil, has reduced the cost that the chain was lubricated. However, since the lubrication tank is fixedly installed in the head changing device, the lubrication tank may topple with the head changing device when the head changing device performs an action. The existing lubricating oil tank can not discharge lubricating oil when dumping at a large angle (dumping over 90 degrees), and further the chain lubricating oil mode of setting the lubricating oil tank in the excavator head replacing device can not lubricate the chain in the use process of the chain.
