October twenty eighth，CCTVCCTV2《Dialogue》The program is broadcast《Behind the white cotton“Hard technology”》，Chief Scientist of China Railway Construction Heavy Industry、Liu Feixiang, Director of Enterprise Technology Center, Picking Cotton“Hard technology”——The domestic cotton picker independently developed by China Railway Construction Heavy Industry Co., Ltd. appeared on the scene.，And leading experts in the field of cotton、Industry representatives explore the high-tech forces behind the cotton industry that you don't know.，Revealing the most advanced scientific and technological genes behind cotton picking！

The cotton picker is“The King of Agricultural Machinery”

On the show，Host Jin Qiang said that the cotton industry is the most traditional industry.，It has the most advanced technology gene behind it.，And this technology gene is inseparable from mechanization.。

Liu Feixiang said，2015，China Railway Construction Heavy Industries has invested in the construction of a shield machine factory in Xinjiang.。At that time, cotton was a pillar industry in Xinjiang.，In the vast cotton fields.，In addition to manual cotton picking，Only imported cotton pickers can be seen.，Everyone was deeply touched by this.。Therefore, after realizing the localization of shield machine,，Tiejian Heavy Industry is fully capable and confident to realize the localization of high-end cotton pickers.。

When the host mentioned the difficulty of developing the cotton picker,，Liu Feixiang vividly compared the cotton picker with the shield machine.，He said，If the shield machine is“King of Construction Machinery”，The cotton picker is“The King of Agricultural Machinery”。Technical Complexity of Cotton Picker、The difficulty of research and development is no less than that of shield machine.。To develop a useful intelligent cotton picker，Need to fuse machinery、Electrical、Hydraulic、Automation、Intelligent and agronomic and other professional technologies。Railway Construction Heavy Industry is a scientific and technological innovative enterprise specializing in research and development of high-end equipment.，Accumulated a lot of common technologies，In addition, the state strongly supports independent innovation.，It took only three years.，The domestic cotton picker independently developed by China Railway Construction Heavy Industry Co., Ltd. was officially launched.。At present，Tiejian Heavy Industry Cotton Picker Series has formed two lines.、Three lines、Four lines、Six lines and other intelligent mechanical type spectrum。Take the six-row cotton picker as an example.，Composed of 100,000 parts，It can harvest 500 mu every day.，That's 2,000 cotton pickers.，The price is 30% cheaper than that of similar models abroad%Above。

What is the core technology of cotton picker?？

When referring to the core technology of the domestic cotton picker independently developed by Tiejian Heavy Industry，Liu Feixiang said confidently，Cotton net harvest rate、Impurity content、Harvesting efficiency and the stability and reliability of the equipment is a measure of whether a cotton picker is advanced or not.、An important sign of good or bad，This is also a matter of great concern to farmers.。And the two items of China Railway Construction Heavy Industries“Secret weapon”，And ensure excellent indexes of that cotton pick.。

The first is picking technology.，The cotton picking head of the six-row cotton picker of China Railway Construction Heavy Industry Co., Ltd. has 3360 shaft spindles.，It's a little mechanical hand that pulls the cotton out of the cotton shell.，The technology is very complex，Is the cotton picked clean?，Did you pick it well?，It all depends on it。At present，The net picking rate and impurity rate of the six-row cotton picker of China Railway Construction Heavy Industry are superior to the national standard.。

The second is the packing technology of the cotton picker.，After several years of technical research,，The R & D personnel of Railway Construction Heavy Industry repeatedly carried out packaging tests in the factory test workshop.，The length of the wrapping film used alone reaches 15 kilometers.，More than 20,000 tons of cotton have been repeatedly packed.。Now Tiejian Heavy Industry Intelligent Cotton Picking and Packing Machine，Industry-leading packaging effect，It has won the praise of farmers.。

The Future of Smart Agriculture

When imagining the future of cotton fields，Liu Feixiang said，Smart agriculture is the direction of development，Realize the intellectualization of high-end agricultural machinery、Intelligence is imperative。Now the cotton picker of Tiejian Heavy Industry has broken through the recognition system of net rate.、Electrostatic induction recognition system and other key core technologies，Next step，How to achieve unmanned harvesting，Unmanned operation，It is the focus of the research of Railway Construction Heavy Industry.。

Future，Railway Construction Heavy Industry will also promote the high integration of agricultural machinery and agriculture.。Leave the cotton picker in the process of harvesting，The quality of the cotton can be automatically obtained、Output、Soil and other information，To provide scientific decision basis for cotton planting.，The intellectualization of agricultural machinery will certainly promote the wisdom of agriculture.。
