Description

Microtractor hydraulic pressure drop tank
Affiliated technical field
The utility model relates to the device of the stores hydraulic pressure oil that uses on a kind of microtractor hydraulic power system, especially is used with main fuel tank, enlarges original hydraulic oil container volume, improves the hydraulic oil reservoir storage, and improves the drop tank of hydraulic oil filtration.
The utility model technical background
At present, the widely used microtractor in rural area, major part is equipped with hydraulic power system, and hydraulic power is provided during for work.Such as, the tractor of band tipping bucket utilizes hydraulic power system to provide hydraulic power for the tipping bucket fluid cylinder.These microtractor hydraulic power system designs are more reasonable, can finish the output of hydraulic power, for work provides power.But according to users' reflection, its fuel tank design also has irrational place.Such as, the hydraulic oil volume of fuel tank is little, when oil pump promotes fluid cylinder work, the hydraulic oil in the fuel tank all pumped does not also reach the fluid cylinder job requirement.Oil hydraulic pump finds time the oil in the fuel tank to work on again, and oil pump is produced greatly wearing and tearing, reduces oil pump working life.The most important thing is that the position that fluid cylinder stretches out does not reach job requirement, hydraulic oil is used up, and fluid cylinder can't be worked.Someone takes to be about to drain when clean at hydraulic oil, replenishes hydraulic oil in fuel tank.This way can guarantee that this fluid cylinder finishes the work.But shortcoming is that the hydraulic oil that fuel tank has more is full of fuel tank when the fluid cylinder recovery is finished in work, and outwards overflow pollutes, and causes the waste of hydraulic oil.The strain position of fuel tank is unreasonable in addition.Filter design increases the inflow pipeline resistance in the inflow pipeline of oil pump, the oil pump working efficiency reduces.
Content of the present utility model
Little in order to overcome existing microtractor hydraulic oil container volume, the hydraulic oil that is held can not satisfy job requirement; The irrational shortcoming in filter design position under the situation that does not change original small-sized dilatory hydraulic power system, enlarges its volume of fuel tank, increases the hydraulic oil reservoir storage; And overcome the irrational shortcoming of strain position, reduce the pump inlet pipe resistance, the oil pump working efficiency is improved.
The technical scheme in the invention for solving the technical problem is: be fixed with dividing plate in enclosure interior, dividing plate is divided into epicoele, cavity of resorption with enclosure interior.The dividing plate center is porose.There is filter core the dividing plate top, between filter core and the dividing plate seal ring is arranged.There is helical spring the filter core top, compresses filter core, and filter core is fixed on the center hole of dividing plate.Pressure cap is arranged at spring top, and the pressure cap holddown spring makes spring can compress filter core.The hydraulic oil inlet duct is arranged on shell body wall, and there is adpting flange the end of inlet duct.Inlet duct is above dividing plate.The center line of inlet duct arrives the case top distance between the 100-200 millimeter.There is flange the inlet duct end, and after flange connected on the main fuel tank of microtractor hydraulic power system, top of the present utility model was just consistent with the main fuel tank top.According to law of connected vessels, hydraulic oil can not flow out from the utility model top.Hydraulic oil at first enters the housing epicoele after entering housing from main fuel tank.Hydraulic oil enters the housing cavity of resorption by filter core again through filtering.Lower housing portion has the hydraulic oil outer pipe.
The beneficial effects of the utility model are: with the utility model flange, be connected on the outlet(discharge) flange of main fuel tank, be about to the utility model and be installed on the hydraulic power system, energy stores hydraulic pressure oil has enlarged fuel tank oil storage volume in the housing, has improved oil reserve.The filter core that filters hydraulic oil is installed in epicoele of the present utility model, away from the oil pump feed pipeline, reduces the pump inlet pipe resistance, and the oil pump worker gives birth to and improves fuel feeding efficient when doing.In addition, the utility model has also obtained beyond thought effect.At first, because the stores hydraulic pressure oil mass increases, when working, oil pump have sufficient hydraulic oil to be in wait state.Utilize stand-by period hydraulic oil can carry out air cooling, radiating and cooling improves the operating conditions of hydraulic oil.Secondly, after main fuel tank was connected, the top of drop tank was consistent with the main fuel tank overhead height, or a little more than main fuel tank, according to law of connected vessels, hydraulic oil can not flow out from the utility model top, has made things convenient for like this and has cleaned filter.When taking out filter core, hydraulic oil can not flow out.The 3rd, through in the hydraulic oil that filters a small amount of remaining foreign material being arranged still, can influence oil pump work, reduce oil pump life.In the utility model, when cavity of resorption stops, utilize the sedimentation principle through the hydraulic oil that filters, the foreign material in the hydraulic oil are deposited on housing cavity of resorption bottom, do not participate in the hydraulic oil circulation, can not exert an influence to oil pump, thereby improve oil pump working life.
