Further, in the above-mentioned hydraulic oil container, the bottom surface of described casing offers sewage draining exit, and, be equipped be used to the dirt-discharging hook that seals described sewage draining exit on the described sewage draining exit.
Further, in the above-mentioned hydraulic oil container, described dirt-discharging hook and described sewage draining exit are bolted to connection.
Further, in the above-mentioned hydraulic oil container, described magnetic devices is magnet.
Further, in the above-mentioned hydraulic oil container, described magnetic devices is calutron.
Further, in the above-mentioned hydraulic oil container, described magnetic devices is at least two, is arranged at the both sides of described sewage draining exit.
Hydraulic oil container among the present invention can according to actual needs, be regulated the temperature of hydraulic oil by the heat-exchanger rig in the fuel tank.This fuel tank has not only avoided because the problem that the rubber seal in the higher hydraulic system that causes of oil temperature wears out easily simultaneously, has also been avoided because the problem of the oil temperature machine that the opens increased frequency that causes on the low side.
On the other hand, the invention allows for a kind of engineering machinery, this project mechanically is provided with above-mentioned any hydraulic oil container.
Further, described engineering machinery is excavator.
Because hydraulic oil container has above-mentioned effect, also has corresponding technique effect so have the engineering machinery of this hydraulic oil container.

Embodiment
Need to prove that in the situation of not conflicting, embodiment and the feature among the embodiment among the present invention can make up mutually.Describe below with reference to the accompanying drawings and in conjunction with the embodiments the present invention in detail.
Referring to Fig. 1 to Fig. 2, there is shown the preferred embodiment of hydraulic oil container of the present invention.As shown in the figure, this hydraulic oil container comprises casing 2 and heat-exchanger rig 1.Wherein, heat-exchanger rig 1 is arranged at the inside of casing 2, is used for regulating the oil temperature of casing 2 interior hydraulic oil.
Particularly, heat-exchanger rig 1 is installed on the inwall of casing 2, and the entrance 11 of heat-exchanger rig 1 and outlet 12 are installed on respectively end face and the bottom surface of casing 2.Generally speaking, the end face of casing 2 also is provided with filler opening 21.
In the present embodiment, heat-exchanger rig can be according to actual needs, and the hydraulic oil in the casing is heated up or lowers the temperature processing.When oil temperature is higher, can pass into cold air in heat-exchanger rig, cold air and hydraulic oil carry out heat exchange, make the hydraulic oil cooling.Cooling to hydraulic oil is processed, and has not only reduced the output of motor to the heat exchange power of hydraulic oil radiator, has also avoided simultaneously because the problem that the rubber seal in the higher hydraulic system that causes of oil temperature wears out easily.When oil temperature is on the low side, can pass into heating installation in heat-exchanger rig, heating installation and hydraulic oil carry out heat exchange, and hydraulic oil is heated up.The hyperthermic treatment of hydraulic oil has been avoided having reached the purpose of energy-saving and emission-reduction because the problem of the low machine that the opens increased frequency that causes of hydraulic fluid temperature simultaneously, has also reduced the oil consumption of the engineering machinery of using this hydraulic oil container.
Need to prove: the heat exchange medium in the heat-exchanger rig 1 can be gas, also can be liquid, and the present invention does not do restriction to its concrete form.
Preferably, continue referring to Fig. 1 to Fig. 2, also show the preferred implementation of heat-exchanger rig 1 among the figure.As shown in the figure, heat-exchanger rig 1 comprises the many pipelines 13 that are interconnected.Be provided with entrance 11 and the outlet 12 of heat-exchanger rig 1 at casing 2, and entrance 11 and outlet 12 are connected with pipeline 13.This heat-exchanger rig is simple in structure, is easy to realize.
Certainly, heat-exchanger rig is except the pipeline communication mode, and to those skilled in the art, known other can carry out the structure of heat exchange also should be within protection scope of the present invention, and the present invention does not do restriction at this.
During implementation, can be at one or more sets above-mentioned heat-exchanger rigs of casing 2 interior layouts, the present invention does not do restriction to its concrete quantity.
