TECHNICAL FIELD

[0001] The utility model belongs to the technical field of snow removal, especially relates to a vehicle-mounted snow-melting agent spreading device. BACKGROUND

[0002] In winter, the snowfall in mining areas in northwest China is large and concentrated, and the road snow is crushed by back-and-forth vehicles and continuously reduced in temperature, forming a special vehicle operating environment under the action of low winter temperature, affecting the traffic efficiency and driving safety, and causing serious safety hazards.

[0003] At present, engineering machinery is usually used to remove snow on roads in mining areas, and artificial snow-melting agent spreading and other technical means are used. As the main deicing means of the unit, artificial snow-melting agent spreading not only has high labor intensity and low efficiency, but also has certain safety hazards, and the snow-melting agent is not evenly spread, which not only causes great waste of snow-melting agent, but also causes certain corrosion to the spreading road.

[0005] The technical scheme of the utility model is as follows: a vehicle-mounted snow-melting agent spreading device, comprising a hopper, an engine is arranged above the hopper, a transmission shaft is connected to an output end of the engine, the transmission shaft is located in the hopper, a throwing mechanism is connected to a lower end of the transmission shaft, the throwing mechanism is located below a discharge port at a bottom of the hopper, the throwing mechanism comprises a throwing disc, the throwing disc is fixedly connected to the transmission shaft at a middle portion of the throwing disc, a fixed sheet is arranged below the throwing disc, a fan-shaped baffle is arranged above the throwing disc, and the fixed sheet is fixed to the discharge port at the bottom of the hopper by bolts.

[0006] A cleaning port is arranged on a sidewall of the hopper above the throwing mechanism.

[0007] A vehicle-mounted support is arranged on a side surface of the hopper.

[0012] The technical advantages of this invention are as follows: 1. This invention uses an engine to drive a spreading disc. Under the centrifugal force of the high-speed rotating spreading disc, the de-icing agent is thrown a certain distance. The higher the rotation speed, the farther the throwing distance, allowing the de-icing agent to evenly cover the snow surface, helping to lower the freezing point of the snow water, thereby effectively melting the snow and improving spreading efficiency. 2. This invention features a cleaning port at the bottom of the hopper for easy cleaning and maintenance. 3. This invention has a de-icing agent agitator at the bottom of the hopper to effectively prevent clogging. 4. This invention has a fan-shaped baffle at the discharge port at the bottom of the hopper, allowing for control of the spreading amount by adjusting the size of the discharge hole, making operation convenient and installation simple.
