[0016] Beneficial effects of the present invention:

[0017] The snow removal device for municipal roads of the present invention is provided with a crushing mechanism, etc. When the snow on the road is frozen, the first electromagnet is energized, and the first electromagnet attracts the L-shaped block after being energized, so that the pushing block moves in the direction close to the roller, the reset spring is compressed, and at the same time, the moving tube is driven to move, at this time, the brush can be pushed to tilt to one side, and the second electromagnet is energized to attract the fixed block, so that the first moving block moves upward, and at the same time, the second spring is compressed, and when the first moving block moves upward, it can drive the mounting block to move synchronously, and then drive the tapered rod to move upward. When snow removal is performed, when the roller rotates, the brush is driven to rotate, and at the same time, multiple fixed columns are driven to rotate. When the fixed column abuts against the side wall of the tapered rod, the roller can be pushed to move along the spline rod in the direction away from the tapered rod. At the same time, the first spring is deformed. When the fixed column passes over the tapered rod, the roller can move and reset under the action of the first spring. This reciprocating process can make the roller reciprocate. When the roller reciprocates, it can be driven by the ball and the connecting rod. The fourth moving block is moved back and forth on the second guide rail, so that the second pushing rod can reciprocate along the inclined groove. When the second pushing rod moves downward along the inclined groove, the third moving block can be pushed to move downward, and the rectangular tube can be driven downward by the guide rod. At the same time, the fourth spring is compressed. When the second pushing rod moves upward along the inclined groove, the rectangular tube can be moved upward and reset under the action of the fourth spring. Such reciprocating movement can make the rectangular tube reciprocate and move up and down. When the rectangular tube moves downward, the pointed cone is driven to move downward synchronously. When the pointed cone ice blocks are against each other, the ice blocks can be crushed. At the same time, the third spring is gradually compressed, and the pushing pin can slide in the spiral groove, so as to push the rotating column to rotate, and then drive the pointed cone to rotate through the support rod, so as to poke the crushed ice blocks, so as to facilitate the ice blocks to separate from the road surface. At the same time, when the drum reciprocates, it can drive the inclined brush to move synchronously, so as to shovel the crushed ice blocks to one side, so as to facilitate the cleaning operation of frozen snow on municipal roads, so as to make the snow removal more efficient and more effective.

This reciprocating process can make the rectangular tube 1502 move back and forth.

[0042] Working principle: When the snow on the road is frozen, the first electromagnet 205 is energized, and the first electromagnet 205 attracts the L-shaped block 201 after being energized, so that the push block 604 moves toward the direction close to the roller 1104, and the return spring 204 is compressed, and at the same time, the moving tube 14 is driven to move, at this time, the brush 1105 can be pushed to tilt to one side, and the second electromagnet 6 is energized to attract the fixed block 501, so that the first moving block 504 moves upward, and at the same time, the second spring 402 is compressed, and when the first moving block 504 moves upward, it can drive the mounting block 505 to move synchronously, and then drive the tapered rod 304 to move upward;

[0043] When snow is being removed, when the roller 1104 rotates, the brush 1105 is driven to rotate, and at the same time, the plurality of fixed columns 303 are driven to rotate. When the fixed columns 303 abut against the side walls of the tapered rod 304, the roller 1104 can be pushed to move along the spline rod 12 in a direction away from the tapered rod 304. At the same time, the first spring 301 is deformed. When the fixed columns 303 pass over the tapered rod 304, the roller 1104 can move and reset under the action of the first spring 301. This reciprocating process can make the roller 1104 reciprocate.

[0044] When the roller 1104 reciprocates, the fourth moving block 902 can be driven to reciprocate on the second guide rail 901 through the ball 907 and the connecting rod 908, so that the second push rod 904 can reciprocate along the inclined groove 903. When the second push rod 904 moves downward along the inclined groove 903, it can push the third moving block 905 to move downward, and drive the rectangular tube 1502 to move downward through the guide rod 1001. At the same time, the fourth spring 1002 is compressed. When the second push rod 904 moves upward along the inclined groove 903, the rectangular tube 1502 can move upward and reset under the action of the fourth spring 1002. In this way, the rectangular tube 1502 can be reciprocated and lifted.

[0045] When the rectangular tube 1502 moves downward, it drives the pointed cone 1505 to move downward synchronously. When the pointed cone 1505 and the ice cubes collide with each other, the ice cubes can be broken. At the same time, the third spring 804 is gradually compressed, and the push pin 702 can slide in the spiral groove 701, thereby driving the rotating column 1503 to rotate, and then driving the pointed cone 1505 to rotate through the support rod 1504, so as to move the broken ice cubes to facilitate the separation of the ice cubes from the road surface. At the same time, when the roller 1104 moves back and forth, it can drive the tilted brush 1105 to move synchronously, so as to shovel the broken ice cubes to one side, which is convenient for clearing the frozen snow on the municipal roads, making the snow removal more efficient and effective.
