This hydraulic oil tank includes the oil tank main part, inhale oil pipe and whirl preventer, the hollow structure that the chamber was held for having to the oil tank main part, it stretches into and holds the intracavity to inhale oil pipe, and inhale the oil absorption mouth of oil pipe towards the diapire of oil tank main part, the whirl preventer is including being relative roof and the bottom plate that just the interval set up, the roof is the ring shape structure, the roof cover is located the one end at the oil absorption mouth place of inhaling oil pipe, the whirl preventer is still including setting up a plurality of guide plates between roof and bottom plate, be formed with the clearance between two adjacent guide plates. The hydraulic oil tank and the engineering machinery can avoid the rotational flow phenomenon at the oil suction port inside the oil tank, and further avoid the cavitation phenomenon of the oil pump.)

1. The utility model provides a hydraulic oil tank, its characterized in that, includes oil tank main part, inhales oil pipe and whirl preventer, the oil tank main part is for having the hollow structure who holds the chamber, inhale oil pipe stretch into hold the intracavity, just inhale oil pipe's oil absorption mouth orientation the diapire of oil tank main part, whirl preventer is including being relative and the roof and the bottom plate that the interval set up, the roof is ring shape structure, the roof cover is located the one end at oil pipe's oil absorption mouth place, whirl preventer still including set up in the roof with a plurality of guide plates between the bottom plate, adjacent two be formed with the clearance between the guide plate.

2. The hydraulic oil tank as claimed in claim 1, wherein a plurality of the guide plates are uniformly distributed on the bottom plate, one end of each guide plate is located at the center of the bottom plate, and the other ends of the guide plates are radially arranged at the center.

3. The hydraulic oil tank as claimed in claim 2, wherein an arc-shaped boss is formed at the center of the bottom plate, and the plurality of flow deflectors intersect with the arc surface of the arc-shaped boss.

4. The hydraulic oil tank as claimed in claim 2, wherein the number of the guide plates is 5 to 7.

5. The hydraulic oil tank as claimed in claim 1, wherein an end of the oil suction pipe remote from the oil suction port is disposed on a side wall of the oil tank main body, and the oil suction pipe extends into the accommodation chamber and is bent toward a bottom surface of the oil tank main body so that the oil suction port of the oil suction pipe faces a bottom wall of the oil tank main body.

6. The hydraulic oil tank as claimed in claim 1, wherein a first partition and a second partition are arranged in the oil tank main body in parallel and at intervals to divide the accommodating cavity into an oil suction cavity, an oil return cavity and an oil drainage cavity in sequence, and the oil suction pipe and the whirl preventer are arranged in the oil suction cavity.

7. The hydraulic oil tank as claimed in claim 6, wherein a first through hole is formed in the bottom of the first partition plate, a filter screen is arranged on the first through hole, a second through hole is formed in the bottom of the second partition plate, an oil drainage port is formed in the bottom wall of the hydraulic oil tank, and the oil drainage port is correspondingly located at the bottom of the oil drainage cavity.

8. The hydraulic oil tank of claim 6, further comprising a liquid level meter disposed on a side wall of the hydraulic oil tank, the liquid level meter corresponding to one side of the oil suction chamber.

9. The hydraulic oil tank of claim 6, further comprising an air filter assembly and an oil return filter assembly disposed on the top wall of the hydraulic oil tank, wherein the air filter assembly and the oil return filter assembly are respectively and correspondingly located above the oil return cavity.

10. A working machine, characterized by comprising a hydraulic tank according to any one of claims 1-9.
