Abstract
The invention discloses a hydraulic oil tank structure of a loading machine, and belongs to the field of hydraulic technologies. The hydraulic oil tank structure is used for a hydraulic system of the loading machine. The hydraulic oil tank structure comprises a box body and a breather. The breather is located at the top end of the box body. The oil return side of the box body is provided with an overflow cylinder. The oil outlet side of the box body is provided with a centrifugal blocking plate. A defoaming partition plate is arranged between the overflow cylinder and the centrifugal blocking plate. The breather comprises an air exchange filter base, breather partition plates, a mounting flange, a respirator and a cover plate. The cover plate is provided with the respirator. At least two breather partition plates are arranged above the respirator. The air exchange filter base is arranged above the breather partition plates. By means of the technical scheme, the problem of generating the high temperature, cavitation and other phenomena in a hydraulic system caused by the fact that too many bubbles exist and are overly large and the problem of oil injection of the breather in the prior art can be solved.
Description
Technical field
The invention belongs to technical field of hydraulic pressure, specifically, particularly relate to a kind of loader hydraulic Oiltank structure for loader hydraulic system.
Background technique
In engineering machinery, loader is generally used for the work operations to bulk material, and the hydraulic system of loader needs to control each hydraulic jack of loader, to realize the different action of loader.And hydraulic oil container is as the basis of whole hydraulic system, be related to the reliability of whole hydraulic system and the working efficiency of loader.
In actual use, the easy produced problem of hydraulic oil container is: 1, the structural design of hydraulic oil container is unreasonable, easily causes the rising of hydraulic oil liquid oil temperature, oily blackening; 2, easily cause hydraulic system to occur in the course of the work forming cavitation, cyclone phenomenon by the abnormal sound that extruding bubble causes because froth breaking is undesirable; 3, the resuscitation apparatus on hydraulic oil container also likely causes the ejection of the hydraulic oil liquid when exchanging with air, occurs oil leakage phenomenon; 4, pollutant easily enters into fuel tank and whole hydraulic system by filtration system, makes the parts of hydraulic system occur damaging, causes working efficiency reduce or quit work.
Summary of the invention
The object of the present invention is to provide a kind of loader hydraulic Oiltank structure, it can solve high temperature that hydraulic system that the phenomenons such as the bubble existed in prior art is excessive, too much cause produces, inhale the phenomenons such as empty, can also solve resuscitation apparatus oil spout problem.
For achieving the above object, the present invention is achieved by the following technical solutions:
Loader hydraulic Oiltank structure described in the present invention, comprise casing, resuscitation apparatus, described resuscitation apparatus is positioned at casing top, and the oil return side of described casing is provided with overflow ladle, be provided with centrifugal barrier plate in the fuel-displaced side of casing, froth breaking dividing plate is installed between described overflow ladle and centrifugal barrier plate; Described resuscitation apparatus comprises ventilation filter seat, resuscitation apparatus dividing plate, mounting flange, breathing mask and cover plate, and its cover plate is provided with breathing mask, and the top of breathing mask is provided with at least two resuscitation apparatus dividing plates, and the top of resuscitation apparatus dividing plate is provided with ventilation filter seat.
Say further, the quantity of the resuscitation apparatus dividing plate described in the present invention is two, and employing is staggered.
Say further, the top of the froth breaking dividing plate described in the present invention is provided with arc shrinkage pool, is distributed with through hole in the below of arc shrinkage pool.
Say further, the overflow ladle described in the present invention has rectangular opening.
Compared with prior art, the present invention has following beneficial effect:
The present invention can reduce the flow velocity of hydraulic oil-returning and the quantity of bubble greatly, avoids emptying phenomenon during tempo turn, avoids hydraulic oil to spray from resuscitation apparatus, makes oil system run more steadily, reliably, avoid the generation of accident, increases the working life of complete machine.

Embodiment
Below in conjunction with accompanying drawing, the present invention is described further.
Embodiment 1: a kind of loader hydraulic Oiltank structure, comprise casing, resuscitation apparatus, described resuscitation apparatus is positioned at casing top, and the oil return side of described casing is provided with overflow ladle 1, be provided with centrifugal barrier plate 3 in the fuel-displaced side of casing, between described overflow ladle 1 and centrifugal barrier plate 3, froth breaking dividing plate 2 be installed; Described resuscitation apparatus comprises ventilation filter seat 4, resuscitation apparatus dividing plate 5, mounting flange 6, breathing mask 7 and cover plate 8, its cover plate 8 is provided with breathing mask 7, the top of breathing mask 7 is provided with two resuscitation apparatus dividing plates 5, and the top of resuscitation apparatus dividing plate 5 is provided with ventilation filter seat 4.
Embodiment 2: the quantity of described resuscitation apparatus dividing plate 5 is two, and employing is staggered.The top of described froth breaking dividing plate 2 is provided with arc shrinkage pool 10, is distributed with through hole 11 in the below of arc shrinkage pool 10.Described overflow ladle 1 has rectangular opening 9.All the other structures are identical with structure described in embodiment 1.
In conjunction with above-described embodiment, the present invention in use, oil return side in hydraulic oil container casing is provided with overflow ladle 1, it is inner that oil return hydraulic oil liquid enters into overflow ladle 1 from return opening, when hydraulic oil liquid reaches rectangular opening 9 at the height of overflow ladle 1 inside, carry out overflow, to reduce oil return jet phenomenon, reduce oil return speed.
The through hole 11 of hydraulic oil liquid on froth breaking dividing plate 2 overflowing to overflow ladle 1 outside arrives in the middle part of fuel tank and intake side.Because the below of centrifugal barrier plate 3 has larger aperture, so fluid can smooth flow.Froth breaking dividing plate 2 can reduce the flow velocity of oil return further, makes hydraulic oil liquid can smooth flow, does not produce huge impact.The aperture of through hole 11 is less, effectively can stop the phenomenon of producing bubbles inside during hydraulic oil liquid flow at high speed, greatly reduces the fuel tank number of bubbles and the volume that enter intake side.When centrifugal barrier plate 3 can be blocked in complete machine tempo turn campaign, due to centrifugal force by centrifugal for the hydraulic oil emptying phenomenon caused to oil return side.
In hydraulic oil casing, due to the percussion of the hydraulic oil liquid that refluxes, with the air of hydraulic oil from hydraulic oil container outward Exhaust Gas time, enter from the upper side aperture of breathing mask 7, form centrifugal motion, cover plate again on resuscitation apparatus 8, two resuscitation apparatus dividing plates 5 collide, and fluid effectively can be deposited on the cover plate 8 on resuscitation apparatus, after aperture on cover plate 8 get back to fuel tank.
