The core operation logic of snowmelt spreader: working principle Deep excavation

[BONOVO]

In the cold winter, snow and ice often bring great trouble to road traffic. Snowmelt spreader, as an efficient auxiliary equipment for snow removal, plays a key role in ensuring the smooth flow of roads. Its core operation logic involves multiple systems working together, and below we will dig deep into the working principle of the snowmelt spreader.

First, the power system

The snowmelt spreader is usually the main power provided by the vehicle chassis, and the vehicle engine transmits power to the various working parts through the transmission mechanism. Common transmission methods include mechanical transmission, hydraulic transmission and pneumatic transmission. Take hydraulic transmission as an example, the engine drives the operation of the hydraulic pump, the hydraulic pump converts the mechanical energy into hydraulic energy, and the high-pressure oil is transported to the various hydraulic actuator components through the hydraulic pipeline, such as the hydraulic motor and the hydraulic cylinder. These hydraulic actuator components then convert the hydraulic energy into mechanical energy to drive the spreading device, conveying device and other components of the snowmelt spreader to work, which is the key to the "power driving principle of the snowmelt spreader". This transmission mode has the advantages of smooth transmission, easy to realize stepless speed regulation, and can adapt to large load changes, so as to ensure that the snowmelt spreader can run stably under different working conditions.

2. Material storage and conveying system

(1) Material storage

Snowmelt spreader is equipped with a special storage bin for storing snowmelt agent and other materials. Storage silos are generally made of corrosion-resistant metal materials and have a certain capacity to meet the needs of different operation scales. The bin body is designed as a funnel, and the bottom gradually Narrows, which is conducive to the smooth slide of materials. At the top of the storage bin, there is usually a feed port to facilitate the addition of snow melting agent. Some snow spreader is also equipped with a material level sensor, can monitor the remaining amount of material in the storage bin in real time, when the material is insufficient, timely remind the operator to supplement, which involves "snow spreader storage bin design and material level monitoring principle".

(2) Material handling

The material handling system is responsible for transferring the snow melting agent from the storage bin to the spreader. The common conveying methods are screw conveying and belt conveying. The screw conveyor is driven by the motor to rotate the spiral blade, and the material is transported from the storage bin to the discharge port along the direction of the spiral shaft by the push effect of the spiral blade. Parameters such as pitch and diameter of the spiral blade are designed according to the characteristics of the snowmelt agent and the requirements of the conveying volume to ensure stable and efficient conveying. The belt conveyor relies on the motor to drive the belt pulley, so that the belt runs on the roller, the material is placed on the belt, and the belt is transported to the specified position with the movement of the belt. The belt conveyor has the advantages of large conveying capacity, long conveying distance and stable operation, which is suitable for large-scale snow melt agent conveying operations, which reflects the diversity of the "material conveying principle of snow melt spread-machine".

Third, the distribution system

(1) Method of spreading

The spreading system of snow melt spreader is the key part to realize the accurate spreading of snow melt agent. The common spreading methods are centrifugal spreading and bilateral spreading. Centrifugal spreading is to use the motor to drive the high-speed rotation of the spreading disc, the material enters from the center of the spreading disc, and is thrown around under the action of centrifugal force to achieve uniform spreading of the melting agent. The speed of the spreading disc can be adjusted by the speed regulating device, so as to control the spreading amount and spreading range of the snowmelt agent. Double-side spreading is carried out through two independent spreading devices to both sides of the driving direction of the vehicle. This kind of spreading method is suitable for the snow removal operation on the wide road surface, and can effectively improve the efficiency of the operation, which belongs to the important content of the "principle of the spreading method of the snowmelt spreader".

(2) Control of spreading quantity

In order to ensure the rational use of snowmelt agent, the snowmelt spreader is equipped with a spread control system. The system realizes the precise control of the spreading amount by adjusting the conveying speed of the material conveying device and the rotating speed of the spreading disc. For example, the operator can input the corresponding parameters on the control table according to the actual situation of the snow thickness, temperature and traffic flow on the road, and the control system will automatically adjust the speed of the conveying motor and the spreading motor, so as to change the conveying amount and spreading range of the snowmelt spreader, so as to realize the "precise control principle of the spreading amount of the snowmelt spreader", and avoid the waste or insufficient spreading of the snowmelt agent.

4. Control system

The control system of the snowmelt spreader is like the human brain, directing the various systems to work together. The control system of modern snowmelt spreader is usually intelligently designed and integrates a variety of sensors and controllers. For example, the speed sensor can monitor the speed of the vehicle in real time, and the control system automatically adjusts the amount of the snowmelt agent according to the speed to ensure that the uniform spreading effect can be maintained at different speeds. In addition, it is also equipped with a temperature sensor for monitoring the ambient temperature, and when the temperature is too low, the amount of snow melting agent is appropriately increased to improve the snow melting effect. The operator can easily set and adjust the parameters of the snowmelt spreader through the operation panel to realize the automatic and intelligent operation of the equipment, which is the embodiment of the operation principle of the control system of the snowmelt spreader.
