[0002] At present, dust suppressant spraying devices are used on coal transportation lines in my country to reduce coal dust pollution along the lines. The existing spray-type dust suppressant spraying devices can only spray dust suppressants according to the fixed coal transport vehicle model and adjust the nozzle angle. When the vehicle model changes, the dust suppressants will be sprayed outside the carriage. This requires workers to climb up the upper part of the spray-type dust suppressant spraying device and adjust the spraying angle by changing the distance of the adjusting screw to achieve the best spraying condition of the spray-type dust suppressant spraying device. This is not only unsafe, but also time-consuming and labor-intensive.

[0003] A set of opposite-spray units of an existing opposite-spray dust suppressant spraying device is provided with two nozzles, and each nozzle baffle requires a servo motor to control to stop spraying at the train hook. Thus, a set of opposite-spray dust suppressant spraying device requires four servo motors, which has high control requirements and high device cost. Utility Model Content

DETAILED DESCRIPTION

[0026] The utility model is described in detail below in conjunction with the accompanying drawings.

[0027] Embodiment 1,

[0028] like Figure 1-8As shown, an angle-adjustable railway dust suppression double-spray type hook-clang stop spraying device comprises two groups of symmetrically arranged double-spraying units, the double-spraying units comprising a liquid supply pipe 1 and a nozzle 3, the liquid supply pipe 1 is connected to the nozzle 3; a first support plate 8 is provided on the upper part of the liquid supply pipe 1, a hinged rod 23 is fixed on the first support plate 8, a second support plate 24 is provided on the upper part of the nozzle 3, a hinged seat 9 is provided on the second support plate 24, and the hinged seat 9 is rotatably connected to the hinged rod 23; a driving mechanism is provided at the lower part of the liquid supply pipe 1, a transverse adjusting screw 12 is connected to the output end of the driving mechanism, an adjusting nut 13 is threadedly connected to the adjusting screw 12, a nut slide 14 is provided at the lower part of the nozzle 3, vertical through grooves 25 are opened on both sides of the nut slide 14, the adjusting screw 12 passes through the two through grooves 25, the adjusting nut 13 is located in the nut slide 14, the side of the adjusting nut 13 is in contact with the inner wall of the nut slide 14, and a gap is left between the end face of the adjusting nut 13 and the inner wall of the nut slide 14.

[0029] The liquid supply pipe 1 and the nozzle 3 are connected via a flexible joint 2. The flexible joint 2 is a flexible rubber joint, and both ends are connected to the liquid supply pipe 1 and the nozzle 3 via flanges.

[0030] Each group of spray units is provided with two liquid supply pipes 1 and two spray heads 3, and the liquid supply pipes 1 are connected to the spray heads 3 in a one-to-one correspondence; the upper parts of the two liquid supply pipes 1 are respectively connected to the two sides of the first support plate 8; the upper parts of the two spray heads 3 are respectively connected to the two sides of the second support plate 24, and the lower parts of the two spray heads 3 are respectively connected to the two sides of the nut slide groove 14.

[0031] A plurality of nozzles 7 are evenly arranged vertically on the nozzle 3 , a nozzle baffle 5 is provided in front of the nozzle 7 , and the upper and lower ends of the nozzle baffle 5 are rotatably connected to the nozzle 3 through an upper shaft 6 and a lower shaft 22 respectively, and the upper shaft 6 is connected to a transmission mechanism 4 .

[0032] The transmission mechanism 4 includes a servo motor 16, a first swing rod 17, a second swing rod 18 and a third swing rod 20. The first swing rod 17 is connected to the output end of the servo motor 16. The first swing rod 17, the second swing rod 18 and the third swing rod 20 are rotationally connected in sequence. Both ends of the third swing rod 20 are rotationally connected with connecting rods 19, and the ends of the two connecting rods 19 are respectively connected to the two upper shafts 6.

[0033] The driving mechanism includes a driving motor 21 and a reducer 11 . The driving motor 21 is connected to the reducer 11 , and an output end of the reducer 11 is connected to the adjusting screw 12 .

[0034] It also includes a first mounting seat 10 , the lower parts of the two liquid supply pipes 1 are respectively connected to the two sides of the first mounting seat 10 , and the reducer 11 is installed on the first mounting seat 10 .

[0035] A second mounting seat 15 is provided on one of the nozzles 3 , and a servo motor 16 is mounted on the second mounting seat 15 .

[0036] When the type of coal transport vehicle changes, the spraying angle needs to be adjusted. Start the drive motor 21, and drive the adjusting screw 12 to rotate through the reducer 11. Under the action of the thread, the adjusting nut 13 moves horizontally on the adjusting screw 12, and then drives the lower part of the nozzle 3 to move through the nut slide 14. Since the upper part of the nozzle 3 is hinged on the hinge rod 23 through the hinge seat 9, the movement of the lower part of the nozzle 3 will drive the entire nozzle 3 to rotate and tilt, thereby achieving the adjustment of the spraying angle. In the process of the nozzle 3 rotating and tilting, the nut slide 14 also gradually tilts. At this time, the adjusting screw 12 slides in the vertical through groove 25, and the gap between the end face of the adjusting nut 13 and the inner wall of the nut slide 14 allows the adjusting nut 13 to adapt to the angle change of the nut slide 14. When the angle needs to be adjusted in the opposite direction, the drive motor 21 is rotated in the opposite direction, the adjusting screw 12 is reversed, and the adjusting nut 13 drives the nut slide 14 and the lower part of the nozzle 3 to move in the opposite direction, so that the entire nozzle 3 rotates and tilts in the opposite direction. In this embodiment, the nozzle 3 is set to an angle change of 20°. The utility model can adjust the spraying angle by mechanical control without workers having to climb onto the upper part of the spraying dust suppressant spraying device, thereby ensuring the safety of the operation, and the adjustment is convenient, saving time and effort.

[0037] The existing spraying device for spraying dust suppressants is provided with a photoelectric detection system, and the signal generated by the photoelectric detection system is input into a programmable controller, and the programmable controller controls the operation of the servo motor. In the utility model, the programmable controller also controls the operation of the servo motor 16 according to the signal generated by the photoelectric detection system. When the photoelectric detection system detects that the coal transport train is located in the hook block, the signal is sent to the programmable controller, and the programmable controller controls the servo motor 16 to start, and the output end of the servo motor 16 rotates to drive the first swing rod 17, the second swing rod 18 and the third swing rod 20 to be linked, thereby driving the upper shaft 6 of the two nozzle baffles 5 to rotate synchronously through the connecting rod 19, so that the nozzle baffle 5 is blocked in front of the nozzle 7, so that the dust suppressant flows into the recovery system for recycling and use, and the dust suppressant stops spraying in the hook block. When the photoelectric detection system detects that the carriage is located in the spraying position, the programmable controller controls the servo motor 16 to reverse, thereby driving the nozzle baffle 5 to rotate to the side of the nozzle 7, and the nozzle 3 sprays the dust suppressant to the carriage normally. In the utility model, each group of spraying units only needs to be provided with one servo motor 16, thereby reducing the control requirements and device costs.
