On the occasion of the 20th National Congress of the Party, the representative of the agricultural machinery industry—YTO LF2204 unmanned tractor, appeared in the “Endeavor new era” theme achievement exhibition.

According to the introduction, the tractor is a configuration of power shift variable speed system, no cab driverless tractor. It has appeared in the global unmanned farm experiment demonstration project of more than 10,000 mu, and was rated as stable by experts. Tractor appears the theme achievement exhibition, is the embodiment that the central government attaches great importance to agriculture.

Large roller is widely used in filling and compaction of high-grade highways, railways, airport runways, DAMS, stadiums and other large engineering projects. Its advantage is strong work quality and high efficiency, but for users, it is the most concerned problem to reduce fuel consumption without affecting the work.

1, choose the appropriate driving speed, not overspeed driving.

2, the locomotive load should be appropriate. Practice has proved that the load of about 85% is the most fuel-efficient and economical, so as not to waste oil.

3，Keep the performance of electrical system and starting mechanism intact. Do not idle the engine for a long time, stop immediately flameout.

4, reasonable selection of mechanical equipment. Proper planning of driving routes, as far as possible to reduce 4 tons of roller idling, empty driving, circuitous, stop in the middle, shorten the total distance of operation, reduce ineffective energy consumption.

5, keep the normal working temperature of the engine, especially in the cold season, try to keep the water temperature at 75-90℃, and use oil according to the season.

6，Regularly remove scale of cooling system, oil scale and sediment of pipeline and muffler.

7，Carry out technical maintenance in a timely and reasonable manner to keep all parts and mechanisms in good technical condition.

8, correct adjustment of the brake, often check the large roller front and rear wheels, keep the tire pressure normal.

9, purify oil, measurement of refueling. If without precipitation filtration before use, impurities in the oil will bring harm to the plunger and needle valve couple, so that the locomotive power decreases and fuel consumption increases. Therefore, general oil should be precipitated for more than 48 hours of reuse.

10，Prevention of oil leakage. Because the roller has been used for a long time, there will be poor contact, improper assembly, mat damage, screw loosening, pipe deformation or rupture, aging seal ring, will cause oil leakage. Therefore, corresponding countermeasures must be taken to timely plug the leak and save oil.

Crawler tractor is widely used in agriculture and the market demand is also great. Crawler tractor has the advantages of small pressure per unit area of soil and good adhesion to soil (not easy to slip), in the soil wet and soft zone has better performance, high traction efficiency. As agricultural machinery giant, the tracked tractors produced by YTO have been favored and concerned by market customers.

Construction machinery is widely used in construction, water conservancy, electric power, roads, mines, ports and national defense and other engineering fields, a wide variety of, is an important lever to drive and economic development, improve infrastructure construction. China’s construction machinery industry, after 50 years of development, has become an important industry with considerable scale and vigorous development, which can produce 18 categories of products of more than 4,500 specifications and models, basically meeting the needs of the domestic market. Its development is also notable.

In recent decades, China’s construction machinery industry has achieved remarkable results in the transformation of development mode and economic structure adjustment, and its comprehensive strength has been rapidly enhanced, and its international competitiveness and industrial status have been greatly enhanced. The technical level and reliability of all kinds of products in China’s construction machinery industry have reached or even exceeded the international advanced level, and there are many famous Chinese brands in the field of construction machinery in the world. Nowadays, the construction machinery industry is moving towards a new direction of more green and environmental protection, to a higher level.
Today, as “carbon peak and carbon neutral” has been written into the government work report and the outline of the 14th Five-Year Plan, green and high-quality development has become the focus of attention from all sectors.

As a construction machinery industry, what can be done in this process? That is to control the exhaust emissions of construction machinery, and research and development and mass production of green, environmentally friendly new energy power products.

Bulldozer as one of the representatives of China’s high-end manufacturing industry, ups and downs experienced nearly half a century of development, with the continuous improvement of construction mechanization requirements, bulldozer technology is constantly moving forward. Looking forward to the future, China’s bulldozer market will be more intelligent, environmental protection and technology.

1. Intelligent

Bulldozer future technology is the main development direction of intelligent, information technology, sensor technology, control technology and other high and new technology applied in bulldozers, operation, use, in order to realize the bulldozer performance improvement and improve, improve work efficiency, improve power performance, improve equipment stability, reduce driver fatigue, and even realize unmanned automatic, intelligent construction.

2. Environmental protection

Green design technology, green manufacturing technology and renewable technology will be the development trend of bulldozer and even the whole construction machinery industry in the future, which is inevitable with the economic development and environmental protection awareness. Whole life cycle of green environmental protection design is at the beginning of the product development design to manufacture, use, maintenance, recycling and reuse of the life, the safeguard function, reliability, on the basis of fully considering environmental properties, improve the utilization rate of resources, reduce pollution, the process of making product technical, environment and economy to achieve coordination.

3. Technology

At present, a new round of scientific and technological revolution and industrial transformation marked by digitalization, networking and intelligence is gestation and rising, with intelligent manufacturing and intelligent products as the new mode of manufacturing. At present, wired and wireless remote control technology of construction machinery products, intelligent control panel, remote control, remote diagnosis, cluster scheduling management, automatic operation, intelligent construction and other technologies based on GPS positioning technology are gradually developed and promoted.

Although in recent years our country bulldozers industry achieved rapid development, but with the foreign advanced enterprise of technology, there is still a large gap in the future should intensify their efforts to research and development of advanced technology industry of our country the bulldozer heavily in improving the reliability of the products at the same time, to speed up the application of new technology, improve product technology content and the technical level; To meet the needs of different users; The development of multi-functional, multi-purpose products, to achieve a machine multi-purpose, high efficiency and energy saving, improve product competitiveness.
