Description

Technical Field

[0001] This invention relates to a rotary spraying device suitable for rapid loading stations, and more specifically to a rotary spraying antifreeze and dust suppression device for rapid loading stations. Background Technology

[0002] Large-scale rapid quantitative loading stations are based on the working principle of large hopper scales. Pre-load the material into the quantitative hopper according to the standard weight of the wagon, and then quickly unload it into the moving wagon via gates and unloading chutes, achieving rapid and accurate loading during continuous dynamic movement. The rapid quantitative loading system mainly consists of a large steel structure, loading machinery, a weighing system, a hydraulic system, an electrical control system, and a software system.

[0003] The purpose of the buffer silo is to store a certain amount of coal to ensure that there is enough coal for loading during normal operation, thereby avoiding frequent starts of the coal conveyor; quantitative weighing loading is used for fast and accurate quantitative loading; loading machinery and equipment are used to control the coal flow during loading; the hydraulic system provides power to various mechanical equipment; the electrical control system is used for monitoring and automatic control of all equipment in the loading system; the automatic lubrication system provides lubrication to the loading machinery and equipment to ensure the service life of the equipment; the software system is used to judge and issue various control commands, adjust loading accuracy, monitor the operating status of each piece of equipment, and record and store loading records and alarm information.

[0004] The station spraying system, as a specialized piece of equipment, is suitable for automatically spraying dust suppressant onto moving train carriages. The system employs a centralized electromechanical control system, with motors serving as the power source for the actuators, enabling functions such as rotation, lifting, and moving up and down. The control system uses photoelectric sensors to collect motion signals from the carriages during train movement, which are then processed and logically judged by a PLC to achieve automated, user-friendly operation.

[0005] However, existing station spraying systems are generally fixed in place, making them inconvenient to move. Although they can rotate, rise and fall, and move up and down, they are all adjusted and controlled as a whole, still occupying a lot of space and making them inconvenient to operate.

[0052] It should be noted that the positioning ring 408 facilitates the installation of the spray pipe 505 on the first extension rod 401, the second extension rod 403, and the third extension rod 406, so that when the first extension rod 401, the second extension rod 403, and the third extension rod 406 are extended, the spray nozzle 506 at the bottom of the spray pipe 505 can spray antifreeze and dust suppressant.

[0053] In this embodiment, preferably, the spraying mechanism 5 includes a water storage tank 501, which is fixedly installed on the base 1. A water supply pipe 502 connected to an external water supply mechanism is provided on one side of the water storage tank 501.

[0057] In this embodiment, preferably, a connecting block 418 is fixedly provided in the middle of the second crank rod 415, and a fourth crank rod 419 is movably connected to the connecting block 418 through a second pin 413.

A sliding rod 422 is connected to the other end of the fourth crank rod 419, and the sliding rod 422 is movably connected inside the limiting groove 420 and the sliding groove 421.

[0060] It should be noted that the setting of the limiting groove 420 and the sliding groove 421 facilitates the movable connection of the fourth crank rod 419, enabling the fourth crank rod 419 to achieve adaptive movement adjustment, which helps to maintain the straightness of the third extension rod 406.

[0061] The specific operational procedures for this application are as follows:

[0062] When in use, first add antifreeze and dust suppressant to the water tank 501. Then, when the vehicle moves to the position, start the servo motor 303 in the rotating mechanism 3. The servo motor 303 can drive the second bevel gear 308 inside the rotating frame 306 to rotate through the first bevel gear 305, so that the rotating frame 306 can rotate. When rotating, it can drive the extension mechanism 4 to rotate. When the second bevel gear 308 rotates, the rotating shaft 307 can also rotate, so as to rotate the first extension rod 401.

[0063] Furthermore, when the first extension rod 401 rotates, it can be pulled by the first crank rod 412, thereby enabling the first extension rod 401 and the second extension rod 403 to rotate via the first gear section 402 and the second gear section 404. The first crank rod 412 pulls the first Z-shaped pulling piece 411, which in turn can pull the second Z-shaped pulling piece 414 via the second crank rod 415, facilitating the movement of the second extension rod 403 and the third extension rod 404. 06 is extended by rotation through the third gear part 405 and the fourth gear part 407, and the third crank rod 416 opens the third extension rod 406. By setting the first crank rod 412, the second crank rod 415 and the third crank rod 416, the straightness and stability of the first extension rod 401, the second extension rod 403 and the third extension rod 406 after extension can be maintained. Furthermore, by pulling the third extension rod 406 at the far end through the fourth crank rod 419, the stability strength is improved.

[0064] Then, the micro water pump 503 in the spraying mechanism 5 is activated, so that the micro water pump 503 draws the antifreeze dust suppressant, which is then transported through the water pipe 504 and the spray pipe 505, and sprayed into the vehicle through the spray nozzle 506.
