Its comprehensive indicators have reached the international advanced level, and various technologies and performances have reached the foreign cotton picking machine index parameters. Some indicators are superior to foreign cotton pickers and can completely replace imports. This product is designed by Guizhou Pingshui Machinery Co., Ltd., affiliated to China Aviation Industry First Group, and China Academy of Agricultural Mechanization Sciences. It was designed in 2002 through the “production, study and research†method, and was developed and produced by Guizhou Pingshui Machinery Co., Ltd. of. In addition to gearboxes, hydraulic pumps and motors, partial valves and cylinder imports, the rest are locally localized, with a localization rate of over 90%. Guizhou Pingshui Machinery Co., Ltd. has become the exclusive domestic company and the third company in the world to be able to produce large-scale self-propelled cotton pickers.
The development of the 4MZ-5 cotton picker successfully filled the domestic gap and broke the monopoly of foreign products. In 2004, the committee organized the 4MZ-5 cotton picker autonomy project and arranged the key support for the national debt fund. It is expected that the annual output of the 4MZ-5 cotton picker can be formed in 2006. China's Guizhou Pingshui Machinery Co., Ltd. produced 10 sets of cotton pickers in 2004. All of them were purchased by the Xinjiang Production and Construction Corps Agricultural Eight Division. In 2005, the Xinjiang Production and Construction Corps signed 20 purchase orders for cotton pickers, including 6 4MZ-5. The type of cotton picker has been delivered, and a new generation of improved cotton picker has completed the joint test.
The successful development of the 4MZ-5 cotton picker has accumulated experience for the autonomy of major technical equipment in China. First, adhere to the "production, study and research" cooperation mode, so that the product design cycle is greatly shortened; second, attach importance to new product development, increase investment in new product development, Pingshui company has developed 4MZ-5 type cotton picker under the condition of tight funds The company has invested more than 28 million yuan; the third is to enhance market awareness and keep up with market demand. Pingshui Company has close contact with the Xinjiang Construction Corps, and has received strong support from the Xinjiang Construction Corps in the assembly site and test cotton fields to develop the cotton picker. It was successfully carried out; the fourth was supported by national policies, and the 4MZ-5 cotton picker was a “national key new product plan projectâ€.
The implementation of the cotton picker autonomy project is of great significance for the revitalization of China's equipment manufacturing industry and the promotion of new rural construction.
First, enhance the awareness of independent innovation and break the monopoly of foreign products. The 4MZ-5 cotton picker adopts advanced hydraulic transmission technology and automatic control technology. It has high technical content and is difficult to manufacture. It is a cutting-edge product in agricultural machinery. Guizhou Pingshui Machinery Co., Ltd. uses its electromechanical integration technology to closely cooperate with research institutes and users, adheres to independent development, and realizes the localization of 4MZ-5 cotton picker, and also strengthens in spare parts supply and after-sales service. The measures have strong market competitiveness. The localization of the 4MZ-5 cotton picker will also promote and drive the downstream equipment, including the transfer equipment, pre-clearing machine, cleaning production line, international standard baler and Other equipment industrialization.
Second, the autonomy of cotton pickers played an important role in industrial back-feeding agriculture and promoted the construction of new countryside. China's cotton planting area is 45 million mu, including 15 million mu in Xinjiang. It is predicted that the demand for cotton pickers in Xinjiang will be 3,750, including 1,700 Xinjiang Construction Corps. At present, the Xinjiang Construction Corps has imported about 120 cotton pickers, and mechanized cotton picking only accounts for 7%. The domestic 4MZ-5 cotton picker is currently priced at about 1.2 million yuan, while the similar imported cotton picker is priced at 160-1.8 million yuan (excluding customs duties and freight). If the Xinjiang cotton corps needs all the cotton pickers changed from import For domestic production, it will save more than 700 million yuan in investment.
In the past two years, with the implementation of the national “three rural†policy, mainland farmers have been reluctant to go to Xinjiang to act as “flower pickers.†In 2004, “picking workers†can only meet 60% of actual needs, making large quantities of cotton unharvestable. And discarding, caused huge losses to the Xinjiang cotton area. According to statistics, Xinjiang collects more than 400,000 people from the mainland each year, and the labor costs paid by the Xinjiang Production and Construction Corps alone amount to 1.2 billion yuan. The popularization and application of domestic cotton picking machines will make mechanized cotton picking a reality and quickly reverse this unfavorable situation. A 4MZ-5 type cotton picker can work up to 4,000 acres per year, which is equivalent to 600 labors. The cost of producing cotton can be reduced by 20% compared with hand-picked cotton, which has good economic benefits. The promotion and use of domestic cotton picking machines will greatly alleviate the social contradictions caused by the migrant workers in the main cotton producing areas of China, and completely solve social problems such as public security, medical care, transportation and schooling for children, and promote and promote the economy of ethnic minority areas. The comprehensive development of society has important significance.
In order to promote the smooth implementation of China's cotton picker autonomy project, the next step is:
The first is to import the domestic key cotton machine into the key supporting parts that cannot be produced in China, implement the exemption of import tariff policy, and implement the import link value-added tax first.
The second is to implement the relevant policies of the agricultural machinery products supported by the state, and to provide financial subsidies to domestic users using domestic cotton pickers.
The third is to speed up the establishment of a quality standard system for machine picking in China. China's current demand for cotton quality standards for hand-picked cotton has seriously affected the enthusiasm of cotton farmers and cotton production enterprises to adopt cotton pickers, which is not conducive to improving the economic benefits of cotton farmers and cotton production enterprises, and is not conducive to China's cotton industry and international The cotton market is in line.
4MZ-5 cotton picker has reached the international level
The 4MZ-5 type cotton picker is a large (five-row) horizontal pick-up self-propelled cotton picker with front-mounted picking workbench, inverted automatic transfer cotton box, hydraulic and mechanical hybrid drive, engine power 186KW. Through the comprehensive testing and practical application of the product by the Xinjiang Production and Construction Corps, the mining rate reached 95.03%, the operating speed was 5.77 km/h, the fuel consumption was 1.7 kg/hr, and the impurity content was less than 10%.
