Abstract
The invention discloses a secondary scouring device of stabilized soil mixing machine rotor motor which comprises two left and right rotor motors; inner cavities of the left and right rotor motors are connected with external devices through value groups; the cavities A of the left and right rotor motors are connected with a value group I; the cavities B of the left and right rotor motors are connected with a value group II; the cavities X of the left and right rotor motors are respectively connected with a value group III; the motor low-pressure return oil ports of the left and right rotor motors are respectively connected with the cavities X of the left and right rotor motors. The secondary scouring device has no need of an external fuel tank or an adaptive flushing valve for cooling and cleaning the hydraulic system, which saves the cost and also improves the hydraulic system environment, as well as effectively maintains the stability of the hydraulic system and realizes the purposes of cooling and cleaning the rotor hydraulic system.
Description
Technical field
The present invention relates to a kind of secondary flushing device of Stabilized Soil mixing machine rotor motor, belong to the Improvement Design of Hydraulic System of engineering machinery field.
Background technique
The Stabilized Soil mixing machine is a kind of road construction work machinery that integrates machinery, hydraulic pressure, electrical technology, the equipment of mix basic unit Stabilized Soil material, the several functions such as have scarifying, stirring, fragmentation and pave is one of the equipment of basic unit's Stabilized Soil mix construction on high-grade highway, urban road, square, airport.
The road-mixed machine hydraulic system is divided four parts: rotor, walking, turn to, auxiliary, its rotor (equipment) hydraulic pressure is a topmost part in the road-mixed machine hydraulic system, for equipment provides power, belong to closed type hydraulic system, mainly by rotor pump, oil purifier, the low tension loop relief valve, the compositions such as left and right sides rotor motor and various sebific ducts, in hydraulic transmission, can significantly improve the quality of liquid in the work loop with the adaptive loop flushing valve of left and right sides motor and then prolong life-span of associated components in the transmission system, many road-mixed machines factory does not generally match flushing valve when selecting rotor motor, reason is that its price is comparatively expensive, selectable unit, therefore many producers do not select it in order to save cost.
Is cost saved again in the effect that how to reach existing flushing valve? become problem demanding prompt solution.
Summary of the invention
In order to overcome defects, the invention provides a kind of cleaning and cooling that can realize road-mixed machine rotor hydraulic system, and the secondary flushing device of the Stabilized Soil mixing machine rotor motor of economy again, it has prolonged the working life of machine.
The present invention for the technological scheme that solves its technical problem and adopt is: a kind of secondary flushing device of Stabilized Soil mixing machine rotor motor, comprise the left rotor motor and the sub-motor of turning right, the inner chamber of described left rotor motor and the sub-motor of being connected is connected with external means by the valve group, A chamber and the valve group one of described left rotor motor and the sub-motor of turning right are joined, B chamber and the valve group two of described left rotor motor and the sub-motor of turning right are joined, X chamber and the valve group three of described left rotor motor and the sub-motor of turning right are joined, and described left rotor motor is connected with its Y chamber respectively with the motor low pressure return opening of the sub-motor of turning right.
The invention has the beneficial effects as follows: the low pressure return opening of left rotor motor is connected with its Y chamber, the low pressure return opening of sub-motor of turning right is connected with its Y chamber, trouble and the cost of adaptive flushing valve have been saved, do not need simultaneously the outer flushing that fuel tank carries out hydraulic system that connects yet, greatly improved original road-mixed machine upper rotor part motor fluid endless form, the quality problems of having avoided former setting method to bring, the reliability of equipment, simplification and the working life of operation have been improved, simultaneously, on original motor, reequiped, not only saved cost but also improved the hydraulic system environment.
Description of drawings
Fig. 1 is the structural representation of left rotor motor of the present invention;
Fig. 2 is the turn right structural representation of sub-motor of the present invention.
Wherein: 1, left rotor motor, 2, the sub-motor of turning right, 3, valve group one, 4, valve group two, 5, valve group three, 6, motor low pressure return opening.
Embodiment
The present invention is described in further detail below in conjunction with drawings and Examples.
As depicted in figs. 1 and 2: a kind of secondary flushing device of Stabilized Soil mixing machine rotor motor, comprise left rotor motor 1 and the sub-motor 2 of turning right, described left rotor motor 1 is connected with external means by the valve group with the inner chamber of the sub-motor 2 of being connected, A chamber and the valve group 1 of described left rotor motor 1 and the sub-motor 2 of turning right are joined, B chamber and the valve group 24 of described left rotor motor 1 and the sub-motor 2 of turning right are joined, described left rotor motor 1 joins with X chamber and the valve group 35 of the sub-motor 2 of turning right, and described left rotor motor 1 is connected with its Y chamber respectively with the motor low pressure return opening 6 of the sub-motor 2 of turning right.
Its working procedure is: the motor low pressure return opening 6 of left rotor motor 1 with the sub-motor 2 of turning right is connected with its Y chamber respectively, utilize like this single direction rotation function of rotor motor, it can be washed when the part oil return, take away foul and heat, wash away approximately 15 liter/mins of flows, not only saved cost but also improved the hydraulic system environment, do not need external fuel tank or adaptive flushing valve to carry out cooling and the cleaning of hydraulic system, safeguard that effectively hydraulic system is stable, realize the cooling of rotor hydraulic system and cleaning, obtained preferably practical effect.
