After the wheat grain is full, the large-scale cross-regional machine harvest of wheat will start from the main production areas of the Yellow River, Huaihe River and the sea, and advance from the south to the north. Summer grain is the first season of grain harvest in the whole year. It is of great significance to ensure the supply, expectation and confidence by doing a good job in wheat harvest, strengthening the reduction of grain crop harvest, striving to capture a good harvest of summer grain, ensuring the completion of the goal of stabilizing grain production this year, and consolidating the basis of grain production throughout the year. At present, the epidemic situation is spreading in many places throughout the country. Can the summer harvest ensure that the particles are returned to the warehouse? Can the wheat harvester operate across regions smoothly? How to minimize summer harvest loss? The reporter conducted interviews on these hot topics.

Side-hung type Hard shaft transmission is adopted, mainly composed of engine, transmission system, clutch, working parts, control device and side-hung belt. One end of the transmission shaft is equipped with a 0.75~2kW single-cylinder two-stroke air-cooled gasoline engine and a centrifugal friction clutch; The other end is installed with a working part consisting of a reducer and a cutting tool. There are many types of working parts, usually circular saw blade, blade or nylon wire. During operation, hang the shackle on the aluminum alloy sleeve of the transmission shaft on the shoulder strap under the operator's shoulder, hold the handle, and swing the hard shaft horizontally to complete the operation of cutting weeds and shrubs. The weight of the implement is about 6-12 kg, and the rotational speed is about 4500-5000 rpm.

​The "Twelfth Five-Year Plan" adopted by the Fifth Plenary Session of the 17th Central Committee clearly requires that the simultaneous promotion of agricultural modernization in the in-depth development of industrialization and urbanization is a major task during the "Twelfth Five-Year Plan" period. The basic way to develop modern agriculture and realize the coordinated development of industrialization, urbanization and agricultural modernization is also an important measure to strengthen the industrial support of agricultural modernization.

​Xie Jianmin, a first-level inspector of the Department of International Cooperation of the Ministry of Agriculture and Rural Affairs, said on the 17th that he would implement three measures to promote the transformation of the food and agricultural system.

1, air filter problem If the air filter is not clean, the intake resistance will increase, the air flow will decrease, and the charging efficiency will decrease, resulting in insufficient engine power. Clean the air filter element or remove dust from the paper filter as required and replace the filter if necessary.

Triangular tape is widely used in agricultural machinery models. The standardized triangular belt has a trapezoidal cross section and no joints in the whole circle. It is divided into seven types: O-type, A-type, B-type, C-type, D-type, E-type and F-type. The O-to-F profile area is gradually increased. The choice of belt model is based on the power delivered, and there is a lot of knowledge in it.

The ideology is contemptuous, and the accidental frequency of agricultural transport vehicles is simple in structure and slow in speed. Most of them are driven on the rural roads where people and vehicles are scarce. Therefore, it is wrong to think that the agricultural transport vehicles do not have to be carefully maintained and operated, and there are problems that can be used for speeding. Overloading and overcrowding are commonplace. However, due to its simple structure, it is determined that its driving performance is not as sensitive, perfect and reliable as a car.

The implementation of the purchase subsidy policy is highly efficient, and the level of agricultural machinery and equipment is rapidly increasing. The central government's agricultural machinery purchase subsidy funds reached 21.5 billion yuan, an increase of 2 billion yuan over the previous year, and it was fully implemented at the end of November. The effect of the subsidy policy was significant, which drove the demand for agricultural machinery consumption to heat up. The production and sales of agricultural machinery industry were booming, the total amount of agricultural machinery and equipment was accelerated, and the structure was accelerated. In 2012, the national total agricultural machinery power reached 1 billion kilowatts, which is expected to reach 1.02 billion kilowatts, an increase of 4.3%. Large and medium-sized tractors are expected to reach 4.9 million units, up 11.2% year-on-year; the number of weak rice transplanters and corn combine harvesters is expected to reach 507,000 units and 233,000 units, up 18.7% and 36.1% respectively. The trend of large-scale, double-type and matching of key crops and key links is obvious. The total output value of agricultural machinery industry above designated size is expected to exceed 300 billion yuan, maintaining a growth rate of more than 20% for six consecutive years, and continues to be in a leading position in the machinery industry.

First, do not use agricultural machinery oil instead of agricultural machinery gear oil and compared with gear oil, low viscosity, anti-wear and load resistance are also weak. If the agricultural machinery oil is used instead of the agricultural machine gear oil, the transmission gear will not be well lubricated, which will cause serious wear of the transmission system gear.
