[0002] With the continuous expansion of the railway network and the increase in operation volume, the problem of weeds on both sides of the railway has become increasingly prominent. In order to ensure the safety of railway trains, it is necessary to regularly remove the weeds on the track to prevent the growth of weeds from affecting the safety of trains.

[0003] The current method of weeding on railway lines mainly relies on manual spraying of pesticides. Due to individual differences among workers, manual spraying of pesticides is prone to uneven distribution of spraying amount, resulting in poor weed control effect.

[0021] As attached Figure 1-6 shown

[0022] The railway line herbicide spraying device includes a frame 1, a traveling mechanism and a spraying unit. The frame 1 is equipped with an orifice plate 2, and a control box 3 is fixedly installed on the orifice plate 2 through a control box mounting frame and bolts. The control box 3 includes a program controller and a battery. The program controller and the battery are installed in the control box 3, and the battery is electrically connected to the program controller.

[0023] Spraying units are respectively provided on the orifice plates 2 on both sides of the control box 3. The spraying units include a support frame 11, a water tank 12 and a windproof nozzle 13. The water tank 12 is fixedly mounted on the orifice plate 2 by means of a water tank mounting frame and bolts. A flip cover is hinged on the water tank 12. A support frame 11 is provided on the orifice plate 2 on one side of the water tank 12. The support frame 11 is a rectangular frame structure and is fixedly mounted on the frame 1.

[0024] Three spray guns 14 are arranged at intervals on the top of the support frame 11. The spray gun 14 is a tubular body with a "T"-shaped cross-section. One end of the spray gun 14 is fixedly connected to the rigid corrugated pipe 15. A windproof nozzle 13 is fixedly installed on the rigid corrugated pipe 15. The windproof nozzle 13 is trumpet-shaped and is connected to the rigid corrugated pipe 15. The rigid corrugated pipe 15 is connected to the spray gun 14.

[0025] A blocking cap 17 is threadedly mounted on the other end of the spray gun 14 . When in use, removing the blocking cap 17 allows the operator to remove obstructions in the spray gun 14 for easy unblocking of the spray gun 14 .

[0026] The circumference of the third end of the spray gun 14 is fixedly connected to the support frame 11 , and the third end port of the spray gun 14 is threadedly connected to the connecting pipe 16 , so that the liquid in the connecting pipe 16 can enter the spray gun 14 through the third end port during operation.

[0027] A water pump is provided in the water tank 12 , and a liquid level sensor (model HDL300) is provided in the water tank 12 . The water pump is connected to the spray gun 14 through a connecting pipe 16 and a four-way pipe 18 . The output end of the water pump is connected to three connecting pipes 16 through the four-way pipe 18 , and the output end of each connecting pipe 16 is connected to the third end port of the spray gun 14 .

[0028] The lower end of the frame 1 is provided with a walking mechanism, which includes a driving shaft 4, a motor 5, a driving rail wheel 6 and a driven rail wheel 7. The driving shaft 4 is movably mounted under the frame 1 through a bearing seat, and the ends of the driving shaft 4 are fixedly mounted with driving rail wheels 6. The frame 1 corresponding to the driving rail wheel 6 is movably mounted with a driven rail wheel 7 through a support shaft 23. The frame 1 on one side of the driving shaft 4 is fixedly mounted with a motor 5, and a driving sprocket 8 is fixedly mounted on the transmission shaft of the motor 5. A driven sprocket 9 is fixedly mounted on the driving shaft 4 corresponding to the driving sprocket 8. A transmission chain 10 is set between the driving sprocket 8 and the driven sprocket 9. When working, the motor 5 drives the driving sprocket 8 to rotate, and the driving sprocket 8, the driven sprocket 9 and the transmission chain 10 cooperate to drive the driving shaft 4 to rotate. When the driving shaft 4 rotates, the driving rail wheel 6 is driven to rotate, and the driving rail wheel 6 and the driven rail wheel 7 cooperate to realize the walking of the frame 1 on the railway track.

[0029] The battery of the control box 3 is electrically connected to the water pump of the spraying unit and the motor 5 of the walking mechanism. The program controller (model PLCS6-800) of the control box 3 is electrically connected to the liquid level sensor, water pump and motor 5. The program controller controls the liquid level sensor, water pump and motor 5 to operate in sequence and in an orderly manner.

[0030] When the herbicide spraying device is in operation, it is first placed on the railway track. Then, the flap of the water tank 12 is opened, the amount of herbicide and water is mixed in an appropriate ratio, and the two water tanks 12 are filled with the prepared liquid. According to the terrain of the railway track section and the distribution characteristics of weeds, the angle of the windproof nozzle 13 is adjusted through the rigid corrugated pipe 15 so that the sprayed liquid can cover the weeds within the optimal range and achieve the best weed control effect.

[0031] The motor 5 of the traveling mechanism is started to rotate by the program controller. With the cooperation of the chain drive consisting of the driving sprocket 8, the driven sprocket 9 and the transmission chain 10, the power is transmitted from the motor 5 to the driving shaft 4 through the chain drive, so that the driving shaft 4 and the driving rail wheel 6 rotate, so that the device can move forward along the railway track.

[0032] After the device starts running on the railway track, the liquid level sensor in the water tank 12 starts working first. When the liquid level sensor detects that there is water in the water tank 12, it will transmit a signal to the program controller, which then controls the water pump to work. The liquid medicine is pumped from the water tank 12 through the connecting pipe and the spray gun 14, and finally sprayed out by the windproof nozzle 13, realizing the automatic spraying of the herbicide while the device is moving.

[0033] When the liquid in the water tank 12 is used up, the liquid level sensor detects that the liquid level in the water tank 12 is too low and transmits a signal to the program controller. The program controller then controls the water pump to stop pumping water, thereby stopping the windproof sprinkler 13 from spraying the liquid. The program controller also controls the motor 5 of the walking mechanism to stop, thereby realizing the automatic stop of the device. After the water tank 12 is filled with liquid, the device will once again continue to automatically spray the herbicide in the above manner.

[0034] As an improved technical solution of the present invention, the support frame 11 includes an upper frame 19, a lower frame 20 and a rotating shaft 21. The upper frame 19 and the lower frame 20 are open rectangular frames. The upper frame 19 and the lower frame 20 are staggered. A rotating shaft 21 is inserted between the upper frame 19 and the lower frame 20. The upper frame 19 is fixedly connected to the rotating shaft 21, and the lower frame 20 is movably connected to the rotating shaft 21. Both ends of the rotating shaft 21 extend to the outside of the lower frame 20. The rotating shaft 21 extending to the outside of the lower frame 20 is provided with an external thread, and a locking nut 22 is threadedly installed on the external thread of the rotating shaft 21. The frame 19 is fixedly connected to the spray gun 14, and the lower frame 20 is fixedly connected to the frame 1. When in use, the upper frame 19 is movably matched with the lower frame 20 through the rotating shaft 21, so that the upper frame 19 can rotate relative to the lower frame 20 around the axis of the rotating shaft 21, thereby adjusting the height of the windproof nozzle 13 on the upper frame 19 so that the sprayed liquid can cover the weeds within the optimal range and achieve the best weed control effect. Then tighten the locking nut 22, and the locking nut 22 clamps the lower frame 20, thereby clamping the upper frame 19 through the lower frame 20, thereby realizing the positioning of the upper frame 19.
