[ China Agricultural Machinery Industry News ] Plant protection mechanization is the latter part of the realization of agricultural planting, modernization, drone plant protection is more suitable for China's national conditions. Compared with manned aircraft/large aircraft spraying, UAV plant protection has the advantages of high operating efficiency, small amount of liquid per unit area, no need for dedicated take-off and landing airports, and good maneuverability. It has matured in Japan and other countries.
It is expected that China's agricultural drone plant protection service will enter a period of rapid growth.
Industry experts pointed out that some helicopters are dispatched once, at least 10,000 mu or more, no loss, and there are many low-altitude obstacles above the cultivated land and low-altitude air traffic control policy restrictions, and its application prospects are limited; land circulation and agricultural moderate scale operation, given by the central government The point is to focus on supporting the planting of about 100 mu. The industry also generally believes that 100-200 mu is a profitable scale. Considering that China's cultivated land resource endowment is different from that of the large farm represented by the United States, it is considered that it may appear in the future. Two large-scale groups, one is a large-scale household of 50-100 mu, and the other is a large-scale household of about 200 mu, which is also suitable for the spraying of plant protection drones. Therefore, plant protection drones will play a leading role in the development of plant protection aviation mechanization in China.
At present, the total amount of agricultural drones in China is relatively low, and the actual application area is small. However, due to its huge advantages in fertilization, pesticide application and pollination, the development prospects are broad. According to incomplete statistics, as of the end of 2014, more than 750 agricultural drones were put into use in China, and the number of flight controllers was more than 1,100, most of which were concentrated in large-scale farmers and small farms. The reference drone plant protection application is a mature country in Japan. At present, there are more than 3,500 drones operating in the field (60% of rice fields are controlled by drones, and nearly 40% of farmland plant protection is controlled by drones.) Complete), flying more than 14,000 people. The area of ​​cultivated land in China is more than 30 times that of Japan. The number of UAVs that are conservatively forecasted for the area of ​​cultivated land is 1/3 of that of Japan. The potential demand for plant protection drones in China is about 35,000.
It is expected that China's agricultural drone plant protection services will enter a rapid growth, and the market space is huge. The “2015 China Land and Resources Bulletin†issued by the Ministry of Land and Resources on April 21, 2016 shows that the area of ​​cultivated land in China is 2.025 billion mu, which is calculated only by 447 million mu of land transfer (end of 2015, Ministry of Agriculture). Pesticide spraying business, if sprayed 5 times a year,
15 yuan per mu, will contribute nearly 35 billion yuan of operating income each year; the moderate scale operation of agriculture provides favorable conditions for the popularization of plant protection drones. With the speed of land circulation in China in recent years, the future demand for plant protection for drones It will be more robust; according to China's 1.8 billion mu of cultivated land red line, China's agricultural drone plant protection market space exceeds 100 billion.
The machine-medicine package is a trend, and the development of special drugs is at the time. Plant protection drones require professional chemicals and auxiliaries that are compatible with the aircraft, high-concentration fine spray and low-volume spray technology, which imposes stringent requirements on the medicinal agent, and the duration and residue of the medicinal solution are required. Most of the pesticide formulations sold on the market are wettable powders, suspending agents, dispersing granules, etc., which are used in traditional artificial spray equipment and are not suitable for the spraying system of the drone; while the existing drone operations mostly rely on experience or reference ground. Spray to determine the dosage and configuration method, often using water suspension agent direct spraying, lack of additives, easy to capacity liquid solution drift, agglomeration, stratification, nozzle blockage, etc., low drug utilization, poor spray effect or even phytotoxicity. Therefore, special anti-agents and special auxiliaries for flying defense are the bottlenecks for the development of plant protection drones. The development of special pharmacies and auxiliaries is another focus of future development.

Ladle Pre-casting
The precast refractory shapes are ideal for making it easy for the industrial users to efficiently make repairs in case of high wear areas within the furnaces. Today, the refractory designs and shapes are conventionally designed to eliminate loses associated with industrial downtime.Precast refractory shapes are pre fired and can be put right into service in your high temperature application.
The precast refractory shapes are ideal for making it easy for the industrial users to efficiently make repairs in case of high wear areas within the furnaces. Today, the refractory designs and shapes are conventionally designed to eliminate loses associated with industrial downtime.
Precast Shapes are manufactured using high quality castable mixes. Insulating, Abrasion Resistant, Low Cement, No Cement, and conventional mixes are available. Alumina contents from 50-99% are available.
Common applications include:
Lintle Blocks
Pier Blocks
Sill Blocks
Jamb Blocks
Hearth Tile
Burner Blocks
Arch Sections
Wood fired Ovens
Trough sections
Our skilled fabricators make custom molds for each application. Most molds are fabricated from steel, but wood and plastic molds are used when appropriate. Carefully selected refractory materials are poured into each mold. Precast Refractory Shapes are oven dried and can be high-fired to maximize performance in your application. We use many of our precast shapes in our own high temperature kilns and furnaces!
