The new science and technology flower mini-harvester has been successfully developed. He repeated trials in his own field for several seasons and he finally accomplished it.
It is understood that the microcomputer is priced at only 1,980 yuan, can cut 3 acres of rice and wheat per hour, with light weight, low energy consumption, reliable performance, easy maintenance and other advantages, can be widely used in grasslands, mountains, hills, slopes Harvest grain and wheatgrass. The machine has been granted national patents last year, and it has achieved three agricultural patents for an agricultural machinery.
Since this product has many advantages over large-scale combine harvesters, it has great market potential. This product will be promoted to rural areas throughout the country during the year.
In June last year, at the head of Wujing Village, near Huhu Town, Jianhu County, Jiangsu, two chairs-sized machines swam like happy fish in the Mailang, next to “rows of straw†neatly “falling down.†This is G. The -88 type of harvester was officially put on the market in Jiangsu after obtaining national patents.
Xu Yushun, the patent inventor of this product, is a local carpenter with more than 40 years of service. In 995, he purchased a Shandong-made miniature harvester that was not yet of practical value from neighbors. He carried out an item-by-item reconstruction according to the drawbacks and problems of the machine. The wheat cut by the side of the field was not a matter of cutting distance. He adjusted it to the right place while experimenting. The wheat was chopped in a disorderly manner, lodging was not, and the auxiliary performance was not enough. He increased the starry wheel. The power of the machine is not enough. He added a new technology of vacuum medium heat transfer for gasoline engine on the basis of the original. A new type of vacuum medium heat transfer technology was developed and recently developed successfully in the Science and Technology Department of the Fourth Middle School in Xinyi City, Jiangsu Province. The dielectric conduction pick-up technology is the use of single (double) tube vacuum closed superconducting liquid circulation heat transfer work principle, overcomes the plumbing resistance, corrosion, 35 2,400, Jiangsu Xinyi City No. 4 Middle School mechanical product sales department Wang Weiping and transmission efficiency is low The three major difficulties. Conductive liquid lifting eggs (also known as "song eggs") in the Lujiang Youmingpi 1 deer system. Everyone knows that the traditional method of production is to use lime, salt, rice husk, and clay to coagulate on duck eggs or eggs. The method generally takes 40 days to mature, not only the workload is large, the yield is low, and the lead content of the preserved egg is high. In order to change this traditional method, Sun Chengjiang, a return worker from Xili Village, Diantou Town, Linyi County, Shandong Province, has developed a more scientific and simple preserved egg production method. The law has been applied for patents from the State Intellectual Property Office. Patent application number 6) Suspected method.
AKIW increased the threshold of young peasants in Longlai Village, Guanzhuang Township, Wancheng, Nanyang City, Nan Province, South China. The newly cultivated nectarine variety “Longxiang No. 1†has applied for a national patent. The average fruit weight is about 400 grams, the largest
The fluorinated mica crystals have very good high temperature resistance, corrosion resistance and light transmission properties, and can work for a long time at a high temperature of 1100°C.
No reaction occurs with strong acids and alkalis; complete light transmittance (pure and transparent). The natural mica plates traditionally used in the observation window of high-pressure boiler water level gauge are all brown, and the light transmittance is not good, and the temperature resistance is in the range of 200-700°C, especially the corrosion resistance is poor. The boiler steam drum water in thermal power plants contains alkali. After reacting with natural mica and alkali, it is washed with hot air and hot water, and it is prone to fluffing, scaling, and being broken. In the short term (about 1-2 months), the water level is not clearly understood. After being broken, it can easily cause leakage. The fluorite mica does not react with the acid-base solution, and does not react with water in the hydration reaction, so that it does not form a layer, does not scale, and does not break. In the long-term (2 to 3 years) scouring of high-temperature and high-pressure water (including acid and alkali), the original clarity and transparency can still be maintained. In China, it has been widely applied to the observation window of steam boiler water level gauge in high-pressure boilers of thermal power plants. It has also been selected by Japanese BBK company and NDK (Colin) company for the observation window of high pressure boiler drum level gauge.
