On the morning of the 13th, Gao Mingfei, director of the Shandong Provincial Bureau of Agricultural Machinery, and the person in charge of the relevant department visited the “Sunshine Administration Hotline†to solve the problem of hard drying of grain for everyone. Gao Mingfei, director of the Shandong Provincial Bureau of Agricultural Machinery, and the person in charge of the relevant department visited the “Sunshine Administration Hotline†(by reporter Li Na) Gao Mingfei, Director of Shandong Provincial Bureau of Agricultural Machinery, proposed to promote the mechanization of grain drying (by reporter Li Na) Qi Lu, October 13 (Reporter Li Na) With the advent of the autumn harvest, the difficulty of drying food has once again become a nuisance for farmers. It has been estimated that due to improper drying or improper drying, food pests, rodents, mildew, and germination are caused. On the morning of the 13th, Gao Mingfei, director of the Shandong Provincial Bureau of Agricultural Machinery, and the person in charge of the relevant department visited the “Sunshine Administration Hotline†to answer this question. Over the years, Shandong Province's post-harvest food processing methods are unscientific, resulting in large food losses. According to the survey, due to factors such as drying, improper drying, and other factors, it caused food rat damage, mildew, and germination. The annual loss of grain is about 5%. It is a pity that the province lost about 4.5 billion jins of grain. However, there are many factors that are difficult to control such as weather, labor, and drying in the drying of roads. Light causes deterioration in the quality of grain quality, and moldy rot and severe losses occur in the light, which not only directly leads to frequent road traffic accidents, but also Also easily lead to secondary pollution of food. In particular, corn mold produces aflatoxin, and both humans and animals are harmful to the body after eating. In order to solve the difficulty of drying the farmers, our province's agricultural machinery department has taken two major measures based on its functions: First, vigorously promote the mechanization of short-term and late grain harvesting. By increasing the supply of various types of combine harvesters, the demand for timely and late grain harvesting of machinery can be guaranteed. In particular, wheat can be directly stored in the warehouse after a timely and late harvest. The phenomenon of road grain drying is becoming less and less, and the time is getting shorter and shorter. The second is to actively promote mechanization of grain drying. In recent years, the agricultural machinery department has used grain drying machinery as the focus of purchase subsidies for agricultural machinery, continuously increased the purchase subsidies, and effectively implemented preferential subsidies and purchases. The subsidy ratio is about 30% of the machinery price. This year alone In half a year, 30 large grain producers purchased 39 grain dryers. The grain drying machinery in the province reached 728, and the grain drying capacity reached 50,000 tons per day. In the next step, the agricultural machinery department will closely focus on solving farmers’ problems in grain drying and promoting grain drying mechanization, and strive to do the following: The first is to strive to expand the timely and late grain harvest area. Further guarantee the supply of harvesting machinery, continue to increase the purchasing subsidies for wheat and corn harvesters, and accelerate the completion of the replacement of wheat and corn harvesters in the province to meet the requirements of quantity, quality, and efficiency. Further improve the efficiency of the use of machinery, make full use of information technology, scientifically dispatch and rationally allocate harvesting machinery resources, and adjust mechanical surplus and shortage according to weather changes and maturation of wheat and corn crops, and the time difference of late grain harvest in different regions. The use efficiency and efficiency of the machine ensure that the food can be collected timely and late. The second is to comprehensively increase subsidies for the purchase of drying equipment. Further increase the grain drying machinery subsidies, increase the proportion of drying machinery subsidies, and encourage qualified cities and counties to implement cumulative subsidies for drying machinery. While subsidizing the main grain drying machinery, the subsidiary machinery and equipment are also included in the subsidy list. To expand the scope of purchase subsidies for grain drying equipment and solve the problem that farmers cannot afford machinery. The third is to increase the intensity of drying equipment to promote identification. The grain drying was incorporated into the province's agricultural machinery innovation demonstration project. According to the situation of grain planting and economic conditions in different regions of our province, the use of convening site meetings and observation meetings, training classes, etc., did a good job in the selection and demonstration of drying machinery and promoted it. A general-purpose model with better quality, reliable use, energy saving and environmental protection, easy operation, and economical application, which achieves multi-use of one machine and improves the efficiency of the use of machinery; promotes equipment and facilities suitable for grain drying needs in our province to meet low-temperature, high-quality drying and conventional food drying. And diversification needs for disaster prevention and robbing; for drying machinery with better adaptability, safety and reliability, priority identification, priority promotion and priority subsidies are given, and advanced and applicable grain drying technologies are vigorously promoted to provide a whole province with Batches can see, learn, replicate typical and templates.
mainly used for earthwork and asphalt applications. New construction and repair work for medium and small scale construction projects, on parking lots, sidewalks, cycle paths, playing fields and sports grounds as well as rolling of joints in road construction.
6~10t large vibratory roller with relatively high pressure and solid capacity should be used for national trunk roads and special roads for automobiles. Road Rollers,Vibrating Road Roller,Mini Road Roller,Drum Road Roller Shandong Luteng Building Equipment Co., Ltd. , http://www.lutengmachinery.com
For the highway below grade 3, or not often compaction work, it is best to equip with about 2t mobile flexible vibration roller.
2. For the cement concrete pavement, the series vibration roller driven by tire can be used;
3. For asphalt concrete pavement, full-drive vibratory roller should be selected;
4. For the bottom layer of high-grade road subgrade, it is better to choose tire roller or tire driving vibration roller for compaction to obtain uniform compaction;
5. When repairing the road surface, the static action roller can be used.
Iv. Selection of pressed materials according to the type:
1. For rock filling compaction, large tonnage roller should be selected to make large block displacement;
2 for clay compaction, it is best to use convex block ramming roller;
3. For the compaction of the mixture, it is better to choose vibratory roller, so as to mix the size of the particles evenly;
4. Heavy vibratory roller should be used for slow rolling for deep compaction, while static action roller should be used for shallow compaction.
