Abstract

The invention provides an oil tank and an excavator, and relates to the technical field of engineering machinery. The oil tank comprises a tank body, an oil suction filter, an oil suction assembly anda shell, wherein the oil suction filter, the oil suction assembly and the shell are arranged in the tank body; the oil suction assembly is arranged on the bottom wall of the tank body; one end of theoil suction assembly penetrates through a box body side wall to be used for communicating with an oil pump; and the oil suction filter communicates with the oil suction assembly and filters oil to befiltered through the side wall of the oil suction filter. According to the oil tank and the excavator, one end of the shell is provided with an opening, the shell sleeves the outer periphery of the oil suction filter through the position of the opening, so that a certain interlayer is formed between the shell and the oil suction filter and communicates with the interior of the tank body through the opening, in addition, the opening end of the shell is kept to extend in the direction towards the bottom wall of the box body all the time, when the oil tank is inclined by a certain angle, due tothe fact that the shell is arranged outside the oil suction filter, the phenomenon that all oil is completely sucked up can be avoided as long as that it is guaranteed that the opening end of the shell is located under the liquid level of the oil, and therefore all parts can be effectively protected, and normal operation of an operation vehicle is guaranteed.

Description

technical field [0001] The invention relates to the technical field of engineering machinery, in particular to an oil tank and an excavator. Background technique [0002] With the development of the economy, in order to further meet people's living needs, the perfection of infrastructure construction has been further improved. Among them, construction machinery is an indispensable role in the construction process, and the improvement and perfection of its various indicators has always been the focus of attention in the industry. Especially small machinery, such as small excavators, etc., are widely used because of their high flexibility and low cost in small engineering projects. Most of the existing small construction machinery has a hydraulic system, so the hydraulic oil tank is an essential device. [0003] Due to the small layout space of the hydraulic oil tank of the existing small construction machinery, part of the oil suction pipeline cannot be installed under the ...
