Description

Technical Field

[0001] The utility model relates to the technical field of train sand adding devices, in particular to a sand box sand filling and dust removal integrated machine for motor vehicles. Background Art

[0002] The sand spreading device of the train is mainly used to increase the friction coefficient between the wheel surface and the track surface when the vehicle starts and brakes, so as to improve the braking performance of the vehicle. The sand spreading device adopts a pressure differential sand spreading unit, which consists of a sand spreading control module, a sand box, a sand spreading unit, a sand box cover and a sand spreading heater. The sand box is used to store sand, and a sand injection port is provided in the sand box. Sand must be injected into the sand box through the sand injection port before each train starts. The railway has very strict requirements on sand, and there are iron standards for particle size, dryness, etc. However, the traditional manual sand adding method transports the processed qualified sand to the train sand adding port and then directly adds it to the train sand box. If the sand clumps during transportation, it will affect the safety of the train.

[0004] Although the above solution separates the agglomerated sand through the filter and vibrator and ensures the sand adding effect, the dust mixed in the sand is difficult to separate and will cause the sand to agglomerate again. It is troublesome for the equipment to separate the dust added to the sand. For this reason, we propose an integrated sand loading and dust removal machine for the sand box of a motor vehicle.
