Abstract
The utility model discloses an external flushing device for high/low pressure working chambers of a separation motor of a spreading machine, belonging to the technical field of spreading machines. The flushing device comprises a flushing valve arranged outside the high/low pressure working chambers of the separation motor of the spreading machine, wherein the oil ports A and B of the flushing valve are respectively connected with the oil ports A and B of a separation pump in series and extend into the working chambers A and B of the separation motor; and the T port of the flushing valve returns oil to an oil tank. The working principle is as follows: when A is the high pressure chamber, B is communicated with T, the working chamber B of the separation motor is flushed; and when B is the high pressure chamber, A is communicated with T, and the working chamber A of the separation motor is flushed. The utility model has the beneficial effects that the flushing device for the high/low pressure working chambers inside the original separation motor is omitted, and an external flushing mode is adopted, thereby avoiding the temperature rise of the separation motor due to flushing, and prolonging the service life of the separation motor.
Description
Technical field
The utility model relates to a kind of motor, specifically is the outside flusher of a kind of paver sub-material motor high-low pressure working chamber.
Background technology
The sub-material motor is the vitals on the paver, and it is that the bituminous mixture in hopper slurry is delivered on the plane that screed can reach uniformly by two strand cages.The sub-material motor is the power source of strand cage, requires continuous operation.For its long service life, must control the temperature of motor.Purging method to paver sub-material motor high-low pressure working chamber at present is: the hydraulic oil of dispensing pump is directly sent into sub-material motor A.B chamber, one reversal valve is installed in the inner chamber of sub-material motor, by the frequent commutation of reversal valve, sub-material motor A.B chamber is taken turns to wash, the weak point of this kind purging method is, the heat that is produced acts directly on the sub-material motor, causes temperature to raise; Had a strong impact on the application life of sub-material motor.
Summary of the invention
For overcoming the above-mentioned deficiency of prior art, the utility model provides a kind of paver sub-material motor high-low pressure working chamber outside flusher, can reduce paver sub-material motor operations temperature, improves the application life and the operating efficiency of sub-material motor.
The utility model is achieved by the following technical solution: the outside flusher of a kind of paver sub-material motor high-low pressure working chamber, comprise that one is arranged on the flushing valve of paver sub-material motor high-low pressure working chamber outside, A, B working chamber that the A of described flushing valve, B hydraulic fluid port are connected and entered the sub-material motor with A, the B hydraulic fluid port of dispensing pump respectively, the T mouth oil return of flushing valve is to fuel tank.
Its operating principle is: when A was high pressure chest, B, T communicated, and the B working chamber of sub-material motor is washed; When B was high pressure chest, A, T communicated, and the A working chamber of sub-material motor is washed.
The beneficial effects of the utility model are: cancelled the inner high-low pressure working chamber of former sub-material motor flusher, adopted outside flushing.Thereby avoided the temperature of the sub-material motor that causes because of flushing to raise.Improve the application life of the sub-material motor of knowing clearly.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Accompanying drawing is the utility model structural representation.
Among the figure: 1, dispensing pump, 2, the sub-material motor, 3, flushing valve, 4, threeway, 5, fuel tank.
The specific embodiment
As depicted in figs. 1 and 2, the outside flusher of paver sub-material motor high-low pressure working chamber comprises that one is arranged on the flushing valve 3 of paver sub-material motor high-low pressure working chamber outside, A, B working chamber that the A of described flushing valve 3, B hydraulic fluid port are connected and entered the sub-material motor with A, the B hydraulic fluid port of dispensing pump 1 respectively, the T mouth oil return of flushing valve 3 is to fuel tank 5.A, B working chamber that the A of flushing valve 3, B hydraulic fluid port connect and enter the sub-material motor with A, the B hydraulic fluid port of dispensing pump 1 respectively by threeway 4.
Claims (2)
