Hydraulic oil tank for road roller

Abstract

The invention discloses a hydraulic oil tank for a road roller. The hydraulic oil tank comprises a hydraulic pump, an oil absorbing filter element, a top cover, a hydraulic oil tank, an oil absorbing stop valve and an oil returning stop valve; one end of the hydraulic pump is connected with the hydraulic oil tank through an oil absorbing pipe, and while the other end of the hydraulic pump is connected with the hydraulic oil tank through an oil returning pipe; the oil absorbing filter element is arranged at an oil feeding pipe at the bottom part of the hydraulic oil tank; the top cover is arranged on the top part of the hydraulic oil tank; the oil absorbing stop valve is arranged on the oil absorbing pipe; the oil returning stop valve is arranged on the oil returning pipe. According to the hydraulic oil tank for the road roller, the structure of the traditional oil tank is improved, namely, the mounting mode of the oil absorbing filter element is mainly improved; the stop valves are mounted at the oil absorbing pipe and the oil returning pipe of the hydraulic oil tank; the improved hydraulic oil tanks are avoided discharging of all hydraulic oil, so that the labor intensity of repair workers can be greatly reduced; in addition, secondary pollution of the hydraulic oil due to oil discharging can be avoided.

Description

technical field [0001] The invention relates to the field of road machinery, in particular to a road roller hydraulic oil tank. Background technique [0002] At present, the hydraulic oil tank of the traditional road roller in the prior art includes oil suction filter element, filter element mounting seat, hydraulic oil tank, hydraulic pump, oil suction pipe and other components, but this type of hydraulic oil tank has the following two defects: [0003] One is that it is inconvenient to replace the oil-absorbing filter element. The oil-absorbing filter element is installed at the bottom of the oil tank through the filter element mounting seat, so before replacing the oil-absorbing filter element, all the hydraulic oil in the hydraulic oil tank must be drained; The installation position is lower than the minimum liquid level of the hydraulic oil tank, and the oil suction pipe is installed at the bottom of the hydraulic oil tank. When the hydraulic pump needs to be replaced a...

Problems solved by technology

[0003] One is that it is inconvenient to replace the oil-absorbing filter element. The oil-absorbing filter element is installed at the bottom of the oil tank through the filter element mounting seat, so before replacing the oil-absorbing filter element, all the hydraulic oil in the hydraulic oil tank must be drained; The installation position is lower than the minimum liquid level of the hydraulic oil tank, and the oil suction pipe is installed at the bottom of the hydraulic oil tank. When the hydraulic pump needs to be replaced and repaired, all the hydraulic oil in the hydraulic oil tank needs to be drained, which not only causes waste of raw materials, but also Indirectly cause environmental pollution problems. If the poured hydraulic oil is refilled into the hydraulic oil tank after maintenance, the hydraulic oil itself is also easily polluted, and it may even cause the hydraulic system to fail, greatly shortening the service life of hydraulic components.
