The specific operation of each part of the invention is as follows:
as shown in fig. 4, when it is required that the clutch is kept in the engaged state, the clutch pushing cylinder 21 pushes the clutch release fork link (not shown in the drawings), the clutch release state holding pin control cylinder 22 pulls out the clutch release state holding pin 28, and then the clutch pushing cylinder 21 releases the clutch release fork link, engages the clutch, and maintains the engaged state;
as shown in fig. 3, when the clutch is kept in an engaged state, an automobile chassis engine (not shown) drives the high-pressure water pump 13, the high-pressure variable oil pump 18 and the low-pressure oil pump 19 to operate through the working power transmission device 5, respectively; as shown in fig. 5, the fog gun 9 is driven to do pitching motion by the low-pressure oil pump 19, the low-pressure oil line control valve 30 and the fog gun pitching motion oil cylinder 32, and the fog gun 9 is driven to do horizontal swinging by the low-pressure oil pump 19, the low-pressure oil line control valve 30 and the fog gun horizontal swinging motor 31; as shown in fig. 6, the fog gun 9 impeller is driven to rotate by a high-pressure variable oil pump 18 and a fog gun impeller rotation driving motor 33;
as shown in fig. 6, when the fog gun 9 is started, the high-pressure variable oil pump opening and closing control cylinder 35 slowly pulls the high-pressure variable oil pump displacement control link mechanism 34 to slowly increase the displacement of the high-pressure variable oil pump 18 from zero to a prescribed displacement, so that the impeller of the fog gun 9 is slowly increased from a stationary state to a prescribed rotational speed;
during the operation of the fog gun 9, water is sucked into the high-pressure water pump 13 from the water tank 3 through the water inlet control valve 50 and the water inlet filter 49, and the high-pressure water pump 13 is pressurized and atomized and sprayed out through the water outlet control valve 51 and the fog gun spray ring 52 by the high-pressure nozzle.
When the fog gun 9 stops working, the high-pressure variable oil pump opening and closing control cylinder 35 slowly pushes the high-pressure variable oil pump displacement control link mechanism 34 to return to zero, so that the high-pressure variable oil pump 18 slowly drops to zero from the specified displacement, and the impeller of the fog gun 9 slowly drops to a static state from the specified rotating speed, and the movement impact can be avoided;
in the operation process of the dust suppression vehicle, the rotation speed of the engine is reduced due to the reasons of braking, parking and the like, so that the rotation speed of the high-pressure variable oil pump 18 is reduced, and at the moment, the high-pressure variable oil pump operation displacement control cylinder 38 can pull the high-pressure variable oil pump displacement control link mechanism 34 to increase the working displacement of the high-pressure variable oil pump 18 by pulling the high-pressure variable oil pump displacement opening and closing control cylinder 35, so that the rotation speed of the fog gun impeller rotary driving motor 33 is kept unchanged, and the impeller rotation speed of the fog gun is kept unchanged.
As shown in fig. 4, when the clutch is required to be kept in a disengaged state, the clutch pushing cylinder 21 pushes the disengaging fork shaft connecting rod of the clutch, the clutch disengagement state keeping pin control cylinder 22 releases the clutch disengagement state keeping pin 28, so that the clutch disengagement state keeping pin 28 returns, and then the clutch pushing cylinder 21 releases the disengaging fork shaft connecting rod of the clutch, and the disengaging fork shaft connecting rod cannot return to the original position due to the blocking of the clutch disengagement state keeping pin 28, so that the clutch is kept in a disengaged state;
as shown in fig. 7, when the low-pressure flushing system is required to operate, the chassis gearbox side power takeoff 40 is engaged to drive the low-pressure water pump 42 to operate, and the low-pressure water pump 42 controls the low-pressure water cannon 44, the high-level side nozzle 46, the back spray nozzle 47 and the front spray nozzle 48 to operate through the low-pressure water path control valve 43 respectively;
when the low pressure flushing system is not in operation, the chassis gearbox side power takeoff 40 is disconnected and the low pressure water pump 42 stops operating.
When the high-pressure water pump belt 14 and the low-pressure oil pump belt 20 need to be replaced, the high-pressure variable oil pump 18, the connecting bolts 27, the high-pressure variable oil pump seat pad 25, and the high-pressure variable oil pump seat positioning pins 26 may be removed, as shown in fig. 3.
Finally, the foregoing description is only of the preferred embodiments of the present invention, and is not intended to limit the scope of the invention, and all equivalent structures or equivalent processes using the descriptions of the present invention and the accompanying drawings, or direct or indirect application in other related technical fields, are included in the scope of the present invention.
