[0022] like Figures 1-7 As shown, a snow and sand removal blowing device for railway track maintenance includes a support frame 1 and pressure blowing mechanisms 2 connected to both sides of the support frame 1. The pressure blowing mechanisms 2 are symmetrically distributed. Pressure gas is sprayed out along the length of the parallel track through the pressure blowing mechanisms 2, adhering to the guide rail and forming a blowing angle with the ground. A guide blowing mechanism 3 is connected between the symmetrical pressure blowing mechanisms 2, which pushes the gas laterally along both sides of the guide rail to push the debris out of the track bed. An installation frame 12 is fixedly connected to the top of the support frame 1. The installation frame 12 has an installation hole 13 inside for installing and fixing the support frame 1. The support frame 1 is fixed to the mobile carrier through the installation frame 12 and the installation hole 13. The pressure blowing mechanism 2 sprays horizontal linear pressure gas downward at an angle to blow between multiple tracks. The guide blowing mechanism 3 guides the blown sand and snow to both sides, increasing the movement distance of the sand and snow, reducing the occurrence of falling back, and improving the blowing efficiency.

[0023] like Figures 2-7As shown, in order to achieve the purging quality of sand and snow removal between multiple tracks, the pressure purging mechanism 2 includes a connecting box 4, a purging box 5, and a linear booster assembly 6. The connecting box 4 is fixedly connected to the upper two sides of the support frame 1 and is arranged symmetrically on the left and right. The purging box 5 is fixedly connected to the bottom of the connecting box 4. An air pump 7 is installed on the support frame 1. The air outlet of the air pump 7 is connected to the connecting box 4 by a pipeline. The linear booster assembly 6 is fixedly connected to the front side of the purging box 5 and is arranged at a downward inclination. The air pump 7 delivers gas to the connecting boxes 4 on both sides through the pipeline. The gas enters multiple purging boxes 5 on both sides, increases the pressure in the purging boxes 5, and blows out the pressurized gas using the linear booster assembly. When moving, the linear gas sprayed in the horizontal direction increases the purging width, which is suitable for purging and cleaning between tracks.

[0024] To improve purging efficiency and maintain the purging area while increasing the force at the purging position, the purging box 5 is V-shaped for cross-gas ejection. The bottom corners of the purging box 5 are chamfered for the inclined installation of the linear booster assembly 6. The purging boxes 5 are arranged at uniform intervals along the length of the connecting box 4. After the linear pressure gas is ejected from the linear booster assembly, it is ejected downward at the chamfered bottom wall of the V-shaped purging box 5. The ejected gases converge after traveling a certain distance. The pressure gas is ejected in a decreasing manner on the front side of the purging box 5.

[0025] To achieve linear pressure gas ejection in the horizontal direction, the linear pressurization assembly 6 includes a connecting pipe 8 and a pressure box 9. One end of the connecting pipe 8 is connected to the chamfer of the purge box 5. The connecting pipes 8 are evenly spaced along the V-shaped cross-section of the purge box 5. The pressure box 9 is fixedly connected to the other end of the connecting pipe 8. The side of the pressure box 9 away from the connecting pipe 8 is tapered. The shape of the pressure box 9 matches that of the purge box 5. The purge box 5 introduces gas into the pressure box 9 through multiple connecting pipes 8. After the outlet side of the pressure box 9 is tapered, the pressure of the ejected gas is increased, so that the gas expands horizontally along the tapered position after being squeezed, thereby achieving linear gas ejection in the horizontal direction and increasing the pressure of the gas.

[0026] like Figures 1-4 As shown, in order to improve cleaning efficiency, the blown sand and snow are guided and pushed to both sides to increase the movement distance of the sand and snow and reduce the fall back. The guiding blowing mechanism 3 includes a connecting plate 10 and a fan 11. The connecting plate 10 is fixedly installed in the middle of the support frame 1. The connecting plates 10 are symmetrically distributed and extend downwards from the support frame 1. The fan 11 is fixedly installed on the side wall of the connecting plate 10 and is arranged at equal intervals along the length direction of the connecting plate 10. The symmetrical connecting plates 10 are between the two blowing boxes 5. At the same time, the horizontal pushing position of the fan 11 is between the upper wall of the track and the support frame 1. When the blowing box 5 blows the sand and snow, the multiple sets of fans 11 in the symmetrical connecting plates 10 push the air to both sides, so that the sand and snow are away from the track bed.

[0027] In use, the operator is fixed on the mobile carrier through the mounting frame 12 and the mounting hole 13, the pressure blowing mechanism 2 is close to the ground and above the multiple tracks, the action surface of the guide blowing mechanism 3 extends to both sides between the track and the support frame 1, the linear pressure gas is sprayed obliquely downward in the horizontal direction, the sand and snow are blown and guided to both sides, the moving distance of the sand and snow is increased, the falling back is reduced, and the blowing efficiency is improved.

[0028] During blowing, the air pump 7 sends the gas into the both-side communication boxes 4 through the pipelines, the gas enters into the multiple blowing boxes 5 on both sides, the pressure is increased in the blowing box 5, the pressure gas is blown out through the linear increasing assembly, the blowing width is increased in the horizontal direction during moving, the linear pressure gas is sprayed obliquely downward at the chamfer of the inner bottom wall of the V-shaped blowing box 5, the pressure gas sprayed from the front side of the blowing box 5 is converged after a certain distance, which is suitable for blowing and cleaning between the tracks, the gas is sent into the pressure box 9 through the multiple connecting pipes 8, the outlet of the pressure box 9 is closed, the pressure of the sprayed gas is increased, the gas is extruded and expanded in the horizontal direction of the closed position.

[0029] After the sand and snow are blown, the symmetrical connecting plates 10 are between the blowing boxes 5 on both sides, and the horizontal pushing position of the fan 11 is between the track upper wall and the support frame 1, when the sand and snow are blown by the blowing box 5, the multiple fans 11 in the symmetrical connecting plate 10 push the air to both sides, so that the sand and snow are far away from the track bed.
