Detailed Description

The road maintenance snow melting salt particle spreading device is used for salt spreading work, wherein the embodiment is described by taking a conventional spreading machine as an example.

The existing purchased or leased snow melting salt particle spreading device is usually modified by taking a truck as a carrier, and the design of a modification plant is completed. The device includes the salt storehouse box, and the salt storehouse is the cuboid structure usually for the temporary storage of snow melt salt, and the size is equivalent with the carriage.

In the conventional design, a salt adding opening is arranged at the top of the salt bin box body and used for adding materials. The bottom of the salt bin box body is provided with a salt outlet for blanking. Wherein, set up the gate of control salt quantity in the salt outlet, the quantity of salt is put in the degree control of opening through the gate.

At present, in the existing equipment (refer to CN214695399U), the up-down projection orientation of the blanking channel and the salt spreading turntable is completely covered, and the salt spreading turntable is a circular disk, and in the spreading process, the distribution of salt particles on the road surface is substantially uniform, and with reference to fig. 1 and fig. 2, it can be known that, in the spreading process of the existing blanking mode (the up-down projection orientation of the blanking channel and the salt spreading turntable is completely covered), the salt particles are thrown out randomly, the blanking is uniform blanking, the upper space of the salt spreading turntable is divided into eight regions by eight salt throwing vertical plates, the process degree refers to fig. 1, after the throwing operation, on the road surface perpendicular to the traveling direction (refer to the shaded region in fig. 1), the distribution density of the salt particles in the roadbed width direction refers to fig. 2, in the figure, the density changes violently in the curvature spreading process, and fig. 2 can see that the above-mentioned snow salt is uniformly distributed on the traveling lane. In an actual road, the rolling areas of the driving wheels are concentrated, the rolling areas are basically concentrated in the range of 1.5-2 m, the middle is a spanning area at the bottom of a vehicle and is not a main snow melting space, and the salt spreading amount can be reduced. Therefore, the snow melting salt is concentrated on the traffic lane at the wheel portion, which is advantageous for reducing the amount of the snow melting salt spread.
