Meteorological disasters have brought huge losses to agricultural production. For example, rice cultivation is often caused by high temperature heat damage, rain and rain, cold damage, rain, hail, wind damage, cold dew, early frost (autumn The impact of meteorological disasters such as frost and cold weather, and the occurrence of reduced production and declining rice quality have seriously affected farmers' income. In recent years, with the development of agricultural modernization, the degree of attention to agricultural meteorology in the agricultural field has also been continuously improved, and instrument systems such as automatic weather stations have been actively used to strengthen meteorological monitoring to ensure the smooth development of agricultural production.
The automatic weather station refers to the ground meteorological observation equipment that can automatically collect, process, store and transmit various meteorological elements according to the set requirements, which can reduce the ground observation workload of the observers and improve the timeliness and quality of observation. Automatic weather stations can generally monitor a number of agrometeorological parameters, including temperature, humidity, rainfall, wind direction, ground temperature, pressure, radiation, effective photosynthesis, sunshine, soil moisture, etc. The construction and application of automatic weather stations are of great significance for improving meteorological prediction, forecasting and service levels and effectively defending against meteorological disasters.
There is a cloud in the farmer's house, where the farmer's land is planted in the sky. This farmland not only shows the hardships of traditional agriculture, but also shows that there is great uncertainty in the agricultural production of watching the world. Because the weather is unpredictable, it is difficult to prevent the adverse effects of extreme weather on crops if there is no effective means to monitor and predict. Nowadays, with the help of agricultural science and technology such as automatic weather stations, agricultural workers have timely and accurate “meteorological expertsâ€. The agrometeorological changes are under control, which not only greatly enhances the ability of modern agricultural disaster prevention and disaster prevention, but also reduces the loss of meteorological disasters. Providing reliable and intuitive meteorological service guarantee for scientific management in the agricultural field, making agricultural planting even more powerful!
Small Cement Silo
1.The cement silo must be erected by a special crane when working. Then place it on the prefabricated concrete and check the verticality between cement silo and the horizontal level. Then weld the bottom of the silo with embedded parts firmly.
2.After the silo is fixed, bulk cement truck transports the cement to site. Then conveying the cement in truck to cement silo by the air pressure of the truck.
3.In the process of conveying cement to storage bin, the operator should press the button of dust collector uninterruptedly to shake off the cement attached to the duster bag to prevent blocking and silo explosion.
4.Once the bag is blocked and the pressure in the silo exceeds the safety pressure value , then open the safety pressure valve to release the inner pressure, to avoid the explosion accident.
Cement silo working principle:
1.Bulk cement truck transports the cement to the site.
2. Conveying the cement in truck to cement silo by the air pressure of the truck.
3. Conveying the cement in cement silo to the Concrete Mixer by the Screw Conveyor.
