The deicing agent storage device is composed of a frame and a deicing agent storage box, and the deicing agent spreading device is composed of a deicing agent spreading plate, a spreading device chassis, a spreading device fan blade and a spreading device funnel. Its characteristics are: the deicing agent spreading device is used to achieve uniform spreading of the deicing agent on the road surface, and the spreading efficiency can be adjusted as needed, avoiding the uneven phenomenon of manual spreading, and having the advantages of simplicity, easy disassembly and assembly, and reduced construction costs; its disadvantage is that when the deicing agent storage box is poured into the agglomerated or hardened deicing agent, it will block the deicing agent storage box discharge port at the bottom of the deicing agent storage box.

Its characteristics are: by setting a driving mechanism, an axle rod and a plurality of crushing blades, the snow-melting salt is crushed to avoid the agglomeration of the snow-melting salt, and the crushed snow-melting salt is sprayed on the road surface through the conveying box and the spray hood; its disadvantage is that the crushed snow-melting salt will block the sieve plate, resulting in poor discharge. In addition, the snow-melting salt is spread by the wind blown by the blower structure, and the spraying area is small because the spray hood faces the ground. Utility Model Content

The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0033] See also Figure 1-5 An automatic stirring snow melting agent spreading device includes a barrel 10 and a spreader 50. A driving device 20 is installed at the bottom of the barrel 10. A scattering device 30 is installed inside the barrel 10. The driving device is connected to the scattering device 30 for driving the scattering device 30 to rotate. A discharge port 11 is provided at the bottom of the barrel 10. The discharge port 11 is connected to the feed port of a screw conveyor 40.

[0034] The agglomerated or compacted deicing agent is stirred and broken up by the breaking device 30 in the barrel 10, and the deicing agent is transported to the spreader 50 by the screw conveyor 40 for uniform spreading. The whole transport process is smooth, and the deicing agent is spread by the spreader over a larger spreading area.

[0035] In a preferred embodiment, see Figure 2 The driving device 20 includes a dual-output reducer 21 and a first motor 24. The dual-output reducer 21 is installed at the bottom of the barrel 10.

The first output shaft 22 of the dual-output reducer 21 extends upward and is connected to the rotating rod 31 for transmission. The second output shaft 23 of the dual-output reducer 21 is connected to the input shaft of the screw conveyor 40 for transmission. The dispersing device 30 and the screw conveyor 40 are driven to operate simultaneously by a set of driving devices 20. During operation, the dispersing device 30 and the screw conveyor 40 work simultaneously.

[0036] In this solution, the first motor 24 is a speed-adjustable motor, and the speed of the screw conveyor 40 is adjusted by adjusting the speed of the first motor 24, thereby adjusting the amount of snow-melting agent spread. In this process, as long as the dispersing device 30 keeps rotating, the dispersing effect can be achieved, because the dispersing device 30 only needs to break up the large pieces of snow-melting agent into small pieces so that the snow-melting agent can pass through the discharge port 11, and the small pieces of snow-melting agent can be further broken up during the conveying process of the screw conveyor 40 and the spreading process of the spreader 50.
