Green and energy-saving shield machine, dredger with automatic dredging system, unmanned tractor & HELIP; … Xinhua News Agency reporters recently visited many state-owned enterprises and found that the equipment manufacturing industry has accelerated towards high-end, intelligent and green, polishing the new business card of "China Zhizao".
The shield machine manufactured by innovative application of green concept successfully went offline.
On May 9th, "China Railway No.1237" rolled off the production line in Zhengzhou, Henan Province. This earth pressure open dual-mode shield machine with a cutter head diameter of 9.16m, a length of 135m and a total weight of more than 1,900t is a shield equipment manufactured by China Railway with innovative application of green concept. In terms of intelligent control, it can realize self-adaptive adjustment and matching with the driving stratum, independently achieve the best matching of driving efficiency and energy consumption, and achieve the purpose of green energy saving.
With its successful off-line, this "big guy" equivalent to three stories high will be exported for the construction of high-speed railway tunnels in Sicily, Italy, to serve the "Belt and Road" construction.

In 2008, the first composite EPB shield machine with independent intellectual property rights "China Railway No.1" went offline, breaking the monopoly position of overseas brands in the field of shield machines; By 2012, "China Railway No.50" was exported to Malaysia, which laid a solid foundation for China shield equipment to go global. Now the green shield machine "China Railway No.1237" has been exported to Italy, and the strong strength of China shield machine has been fully demonstrated.
According to reports, up to now, the total number of orders for China Railway Shield Machine and TBM (Hard Rock Tunneling Machine) has exceeded 1,500, which have been exported to 32 overseas countries and regions. China Railway Shield Machine has become a "new domestic product" that polishes the "China brand" and sells well overseas.
"Steel behemoth" guards the safe passage of "Golden Waterway"
The place where the Yangtze River flows into the East China Sea is China’s waterway transportation hub and international shipping trunk line. In the busy Yangtze River estuary, a blue and white "steel behemoth" guards this "golden waterway" day and night. This is the "New Sea Tiger 8" wheel of Shanghai Waterway Bureau under CCCC.

In May every year, the deep-water channel of the Yangtze River estuary enters the flood and siltation season, and the amount of sediment coming from the upstream increases obviously, which has an impact on the safe passage of the "Golden Waterway" and the normal operation of the Shanghai International Shipping Center. As a large-scale trailing suction dredger independently developed by China, "Xinhai Tiger 8" has a total length of 130.3 meters, a width of 25.6 meters and a depth of 9.2 meters. It adopts the largest advanced equipment such as mud pump frequency conversion drive and automatic dredging system in China, and is a well-deserved "dredging tiger" in the Yangtze River estuary.
The operator stood in front of the console of the new Haihu 8, and with the help of the advanced automatic dredging system, the huge "rakes" on both sides of the ship slowly rose and plunged into the water. "These hoes have sensors that can monitor underwater conditions in real time. After using the automatic dredging system, not only the construction efficiency is obviously improved, but the daily fuel consumption is also reduced from 40 tons to about 35 tons. " Song Jiakai, the captain of "New Sea Tiger 8", said.
High-end agricultural machinery and equipment insert "scientific and technological wings" for agricultural modernization
With a finger, a tractor with a height of more than 3 meters can automatically plan the path, travel and avoid obstacles, and can also independently control the farm tools for unmanned operation, with an operating accuracy of less than 2.5 cm — — The reporter walked into the factory of China Yituo Group Co., Ltd., a subsidiary of SINOMACH, and the Dongfanghong LF2204 driverless tractor with a "smart brain" was eye-catching.

Xue Zhifei, deputy general manager of China Yituo Datuo Company, told the reporter: "The effective improvement of the working accuracy of unmanned tractors has made the crops straighter, and the lighting and ventilation conditions are better, which not only increases the effective planting area by 5% to 10%, but also helps to increase production and income."
The reporter learned from China Yituo that under the blessing of "black technology", in addition to unmanned tractors, a series of high-end agricultural machinery and equipment, such as multifunctional self-propelled intelligent pepper direct seeding machine and high-efficiency grain combine harvester, have been widely used in agricultural practice, significantly saving operation time, improving operation efficiency and increasing farmers’ income, which has inserted "scientific wings" to promote agricultural modernization.
In recent years, state-owned and state-owned enterprises have vigorously carried out key core technology research and promoted China to create new breakthroughs; Strengthen technological transformation and intellectual empowerment, comprehensively improve the level of process technology, product quality and safety, and promote China’s quality to show new results; A large number of China brands such as "China Road", "China Bridge", "China Port" and "China Car" are well-known overseas, which has promoted the China brand to take on a new look … … Driven by innovation, winning the market by quality and leading the future by brand, "China Zhizao" is gathering the majestic power of high-quality development.
