With the construction of high-speed railways, the traction load of electric locomotives has increased day by day, and improving the adhesion performance of locomotives has become a crucial issue. Therefore, in order to ensure the normal operation of rail vehicles, sand spreading operations are required according to actual needs during the movement of rail vehicles.

[0015] The present invention has the following beneficial effects:

[0016] (1) According to the present invention, when the locomotive track sand spreading device is used, sand can first be put into the interior of the sand storage box by adding material, and the sand and gravel are guided to the bottom plate through the sand guide inclined plate. When the locomotive starts to start, the DC motor at the bottom of the protective cover is first started, and the output end of the DC motor drives the output shaft to rotate. The rotation of the output shaft drives several sliding frames on the fixed block to rotate. The rotation of the sliding frame drives the toggle rod to rotate. At this time, the rotation of the toggle rod and the driving plate are squeezed. When the toggle rod and the driving plate are squeezed, the toggle rod toggle the arc-shaped blocking piece at one end of the driving plate to squeeze the squeezing spring along the arc-shaped rod. At this time, the arc-shaped blocking piece is separated from the sand inlet hole on the inner wall of the sand outlet tube. Such a setting is conducive to opening the sand inlet hole on the sand outlet tube. At this time, the sand enters the interior of the sand outlet tube through the sand inlet hole, thereby ensuring that when the device is used, the sand can be controlled to enter the interior of the sand outlet tube through the sand inlet hole and be discharged to the locomotive track through the sand outlet pipe at the bottom of the sand leakage tube.

[0017] (2) According to the present invention, when the device is not in use, under the elastic force of the squeezing spring, the squeezing spring squeezes the arc-shaped blocking piece along the arc-shaped rod to move toward one end close to the sand inlet hole. This arrangement is conducive to the arc-shaped blocking piece blocking the sand inlet hole, isolating the sand inside the sand storage box from contact with the outside air, thereby preventing external moisture from entering the interior of the sand storage box from the bottom of the sand outlet pipe, preventing the sand from getting damp and agglomerating, and thus preventing the agglomerated sand from clogging the inside of the sand outlet pipe, thereby ensuring that the sand in the device is discharged smoothly; in addition, the sand can be screened through the sand outlet tube to prevent large pieces of sand from clogging the sand outlet pipe.

[0018] (3) The present invention provides a breaking mechanism. When the toggle rod and the driving plate are squeezed, the toggle rod drives the arc-shaped blocking piece at one end of the driving plate to squeeze the squeezing spring along the arc-shaped rod. The arc-shaped blocking piece drives the rotating column at one end of the connecting rod to move along the outer wall of the sand outlet tube. At this time, the rotating column drives the gear to move along the gear ring. Under the meshing action of the gear ring, the gear drives several breaking rods on the rotating column to rotate. This arrangement is conducive to the rapid rotation of the breaking rod to break up the agglomerated sand near the sand inlet hole, thereby accelerating the rate at which the sand enters the sand outlet tube through the sand inlet hole. On the other hand, it is conducive to quickly stirring the sand near the sand inlet hole to avoid the sand from clogging the sand inlet hole, thereby ensuring the stable operation of the device.

[0019] (4) According to the present invention, a reset mechanism is provided, when the toggle rod and the driving plate are squeezed, the toggle rod drives the arc-shaped blocking piece at one end of the driving plate to squeeze the squeezing spring along the arc-shaped rod, and the arc-shaped blocking piece drives the rotating ring 1 at one end of the bottom rotating rod to move, and the rotating ring 1 moves to drive the rotating ring 2 at one end of the connecting rod 1 to slide downward along the fixed rod, and the fixed rod slides downward to drive the moving frame to squeeze the reset spring downward. At this time, the moving frame drives the moving ring inside the limiting groove at one end of the rotating sleeve to move downward, and the moving ring moves downward to drive the toggle rod at one end of the connecting rod 2 to move along the sliding frame toward one end close to the fixed block. When the toggle rod is out of contact with the driving plate, the squeezing spring drives the arc-shaped blocking piece to reset. Such a setting is conducive to the arc-shaped blocking piece to move back and forth, thereby ensuring that the sand material continuously enters the sand outlet tube from the sand inlet hole.

[0020] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] The sand output control mechanism 2 includes a sand output cylinder 201 fixedly connected to the top of the bottom plate 13, a protective cover 202 fixedly connected to one end of the sand output cylinder 201 away from the bottom plate 13, a DC motor 203 fixedly connected to the bottom of the protective cover 202, an output end of the DC motor 203 fixedly connected to an output shaft 204, and an end of the output shaft 204 close to the DC motor 203 fixedly connected to a fixed block 205.

[0037] The sand output control mechanism 2 also includes a plurality of sliding frames 206 fixedly connected to the side wall of the fixed block 205, and the sliding frames 206 are slidably connected to the toggle rod 207 inside.

At this time, the arc-shaped blocking piece 211 is disengaged from the sand inlet hole 208 on the inner wall of the sand outlet tube 201. This arrangement is conducive to opening the sand inlet hole 208 on the sand outlet tube 201.

This arrangement is conducive to the breaking rods 305 rotating to quickly break up the agglomerated sand near the sand feeding hole 208, thereby accelerating the rate at which the sand enters the sand discharge tube 201 through the sand feeding hole 208. On the other hand, it is conducive to quickly stirring the sand near the sand feeding hole 208 to avoid the sand from clogging the sand feeding hole 208, thereby ensuring the stable operation of the device. By setting the reset mechanism 4, when the toggle rod 207 is squeezed with the driving plate 212, The toggle rod 207 toggles the arc-shaped blocking piece 211 at one end of the driving plate 212 to squeeze the squeezing spring 213 along the arc-shaped rod 210. The arc-shaped blocking piece 211 drives the rotating ring 1 402 at one end of the bottom rotating rod 401 to move. The rotating ring 1 402 moves to drive the rotating ring 2 406 at one end of the connecting rod 1 403 to slide downward along the fixed rod 405. The fixed rod 405 slides downward to drive the moving frame 408 to squeeze the reset spring 407 downward. At this time, the moving frame 408 drives the rotating sleeve 409 to move.
