Description
The utility model is used for pitch sprinkling car.
The bitumenpump of existing bituminous distributor is driven by mechanical system, and moving by manually pulling lever of spreading tube realizes.Therefore, the rotating speed of bitumenpump can only be selected according to the gear of automobile gearbox, can not steplessly change, and the size of pitch sprinkling amount can not be selected arbitrarily in determining scope, and the position of spreading tube can not arbitrarily be adjusted as required, and what cannot say for sure to demonstrate,prove pitch spills the cloth quality.
The purpose of this utility model is exactly the stepless variation of rotating speed energy that will make bitumenpump, in the scope of determining, can select pitch sprinkling amount and the random position of adjusting spreading tube arbitrarily, guarantee that each nozzle of spreading tube has equal expulsion pressure, it is even to make pitch spill cloth in the spreading tube length range, and that improves pitch spills the cloth quality.
To achieve these goals, this bituminous distributor has adopted hydraulic-driven and control system.Fluid power system is used for driving bitumenpump, and it is made of variable capacity oil pump, fixed displacement oil motor.The power transmission circuit of hydraulic-driven bitumenpump is on pitch sprinkling car: the power of automobile engine imports propulsion box into through the power take-off gear of clutch, gearbox, output shaft and Cardan shaft by propulsion box reaches variable capacity oil pump to drive variable capacity oil pump afterwards, and variable capacity oil pump drives fixed displacement oil motor again and drives bitumenpump; Propulsion box is just passed to the energy of automobile engine the variable capacity oil pump of fluid power system with moment of torsion and rotating speed form like this, variable capacity oil pump is transformed into hydraulic pressure to the mechanical energy that is obtained can pass to fixed displacement oil motor, last fixed displacement oil motor can be converted to the bitumenpump that mechanical energy drives the pitch system with hydraulic pressure again, and bitumenpump pumps into spreading tube with certain pressure and flow with pitch.If the flow of variable capacity oil pump is Q, discharge capacity is q
1, rotating speed is n
1, the discharge capacity of fixed displacement oil motor is q
2, rotating speed is n
2, n is then arranged
2=Q/q
2=q
1n
1/ q
2Because the discharge capacity q of fixed displacement oil motor
2Be constant, so in the rotation speed n of variable capacity oil pump
1One regularly, the discharge capacity q of regulated variable oil pump
1Just can change the rotation speed n of fixed displacement oil motor
2, the maximum (top) speed of fixed displacement oil motor is decided by the maximum stream flow of variable capacity oil pump, its minimum speed is decided by the minimum regime flow of variable capacity oil pump.Because the discharge capacity q of variable capacity oil pump
1Can step-less adjustment, so the rotation speed n of fixed displacement oil motor
2Also can steplessly change, thereby realize the rotating speed of step-less adjustment bitumenpump, in determining scope, select the purpose of pitch sprinkling amount arbitrarily.Hydraulic control system is used for controlling the position of spreading tube, it is made up of multiple directional control valve, spreading tube sidesway oil cylinder, spreading tube hoist cylinder, spreading tube nozzle switch oil cylinder and operating mechanism, wherein multiple directional control valve is formed in parallel by three manual three-position four-way valves, they are connected in series with spreading tube sidesway oil cylinder, spreading tube hoist cylinder, spreading tube nozzle switch oil cylinder respectively, constitute spreading tube position and spreading tube nozzle switch control loop.When oil pump during, only need to handle multiple directional control valve and just can control the spreading tube upper and lower, left and right and move and the opening or closing of spreading tube nozzle to the hydraulic control system fuel feeding.The oil of hydraulic control system can be supplied with by independent oil pump, and oil pump obtains power by propulsion box from automobile engine and drives.Oil also can be supplied with by the auxiliary oil pump in the variable capacity oil pump.
