April 15，《Hunan Daily》The important news edition is《Taking seedlings is like picking up vegetables.，There are throwing seedlings“Run up”——Zoomlion agricultural machinery“Dark horse”Run》As the title，This paper reports the first orderly rice seedling throwing machine developed by Zoomlion.，Promoting Mechanized Rice Transplanting with Scientific and Technological Innovation。The following is the original report.。
Hunan Daily All Media Reporter Hu Panpan Correspondent Luo Yi Mao Zhouyu
Hunan is the largest rice producing area in China.，But mechanized transplanting has always been a short board.。Zoomlion, a Leading Equipment Manufacturing Enterprise in Hunan, Developed the First Orderly Rice Seedling Throwing Machine in China。
Before taking the seedlings，Give the seedlings first“Comb your hair”；When clamping seedlings，Control the strength like picking up food.；When throwing seedlings，Have“Runway”Run up，Let the seedlings fall into the field accurately.、Stand firm……Development of new technology of agricultural machinery，Reasonable close planting is realized、Proper and orderly shallow planting，The efficacy is greatly improved.。
April 11，The reporter came to Hudi Village, Huangtudian Town, Dingcheng District, Changde City.，Field Experience of New Changes in Rice Planting Brought by Orderly Seedling Throwing Machine。

More than 20,000 tests，Seedling picking without damaging seedlings
In the village of Lake Bank，Zhou He, a big grain grower, drives an orderly seedling throwing machine.，With his father, Zhou Jianguo.，It only takes a few minutes，He threw the seedlings of a hill field.。

The reporter boarded the rice seedling throwing machine and took a closer look.，Inlet of seedling tray of seedling thrower，There are 14 seedling combing boards.。
“In order to achieve orderly seedling taking,，Give the seedlings first‘Comb your hair’，Straighten out the seedlings。”Wang Bo, manager of Zoomlion Planting Machinery Platform, introduced.，The seedlings are in the process of growing.，The branches and leaves will cross each other.，Comb the seedlings before taking them.，The process of taking seedlings in the back will not be chaotic.。
Before seedling taking by seedling throwing machine，Give the seedlings first.“Comb your hair”。Correspondent Luo Wei took Mao Zhouyu's clip.
“Comb your hair”The seedlings are more regular.，The 13 rows of seedlings on the seedling tray are divided into 13 paths to enter the seedling taking link.。13 pairs of seedling picking belts circulate on the machine，Clamp each pair of seedling taking belts first，Take out the seedlings in the seedling tray and then loosen them.，Let the seedlings fall onto the seedling throwing belt below.。
“Taking rice seedlings is like picking up food with chopsticks.。The principle is simple，But it is very difficult to achieve this step.。”Wang Bo introduced，How much force is used to take out the seedlings?，Very particular。It's more powerful，It will hurt the seedlings.；The force is small，No emergence of seedlings。Different varieties、Different seedlings、Different seedling soil，Will cause the weight of the seedlings to vary，The force used to take the seedlings is also different.。
Through 5 years of practice，After more than 20,000 tests,，Wang Bo led the team to successfully develop flexible seedling taking technology.，Debug out“Just right”The strength of，Ensure that the seedlings are not damaged during seedling picking。

There are throwing seedlings“Run up”，Steady in the field
Orderly taking of seedlings is particular，Orderly seedling throwing is more difficult.。

The rice seedling thrower ran forward with a roar.，The water is surging in the field，Plant rows of green seedlings。
“Seemingly‘The heavenly maids scatter flowers’，In fact, it is precise and orderly。”Ma Lixin, deputy manager of Zoomlion Planting Machinery Platform, introduced.，13 seedling throwing belts at the tail of the seedling throwing machine，Like“Runway”The same is the seedling“Run up”。After the seedling obtains the inertial power,，Make a parabolic motion again.“ Diving ”Irida。
The seedlings are on the track.“Run up”After，Make a parabolic motion“ Diving ”Into the mud。Correspondent Luo Wei took Mao Zhouyu's clip.
The 13 runways vary in length.，After the seedlings are thrown out, the distance is naturally different.。Via the button on the dashboard，The rotation speed of the seedling throwing belt can be adjusted by one key.，Thereby adjusting the row spacing of the seedlings.、Plant spacing。Stepless adjustment of line spacing from 210 mm to 320 mm，Plant spacing has 8 gear，It can meet the needs of different farmers.。
Seedlings should be in accordance with the established row spacing.、Plant spacing into the field，And make sure it's in the mud.，Instead of floating on water.。
Where is the mystery?？Ma Lixin narrated，Can the seedlings be planted firmly in the soil?，Depends on the volume of pot soil at the bottom of the seedlings、Weight，And the speed and height of the seedling-throwing belt。In the course of the study，It has appeared that the bowl soil is too light.，A condition that causes seedlings to float on the surface of the water.。The research team has passed the trial for nearly two years.，Improve the seedling tray，Make the volume of the rice bowl larger、The bowl soil becomes heavy.，To successfully solve this problem.。

“Throw 13 rows of seedlings at a time，More rows than rice transplanter，Work faster。The machine throws the original nutrient soil at the root of the seedling.，No turning green period after entering the field，The tillering is fast，That's an extra week of growth.，Win more time for double cropping rice planting，It can effectively avoid late rice encountering cold dew wind.。”As the earliest group of users of the ordered seedling thrower,，Zhou He is really benefiting。
Zhou He said，A rice seedling thrower replaces more than a dozen people.，4 to 5 mu of seedlings are thrown every hour.，Aves time, labor and cost，Planting double cropping rice is guaranteed。At the same time，Compared with throwing seedlings by hand，Reasonable close planting can be achieved by orderly machine polishing，Ventilation of the seedlings、The lighting degree and the like are optimized.，Is beneficial to the growth of crops。

Agricultural machinery is available“Wisdom”，More and more“ Clever ”
“After 90”Zhou He, a new farmer, is keen to use and promote new agricultural machinery.。April 11，Zhou He stood at the edge of the field and carried out unmanned operation with a flat remote control seedling thrower.，Attract many villagers to watch.。

Compare and contrast，Seedlings thrown in remote pilotless mode，The effect is not inferior to that of manual driving seedling throwing mode.。
How is this achieved?？
“Through more than ten years of research，We have endowed the seedling thrower.‘An intelligent brain’。”Wang Futong, Director of Intelligent Institute of Zoomlion, introduced.，Sensors installed on the transplanter can collect field information and operating environment information.，Hand over to“An intelligent brain”Automatic route planning，So that that rice seedling throw realizes driverless operation。
Unmanned rice seedling thrower“Diligent and eager to learn”，Not only collecting job data，It can also learn the operation habits of the operator.，Make yourself more“ Clever ”。
Wang Futong's Operation of Orderly Rice Seedling Throwing Machine with Flat Remote Control。Correspondent Luo Wei took Mao Zhouyu's clip.
“As long as there is an intelligent terminal.，It can remotely control the seedling thrower to carry out unmanned operation.。”Wang Futong said，A radio station was installed on the rice seedling thrower.，The signal can radiate around 10 kilometers.。Scene，He operates the mobile phone、Flat plate、 Computer ，The rice seedling throwing machine can open the remote control automatic driving mode.。Start or stop the seedling thrower、Forward or backward，Depends on where the fingertips slide.。
“That sounds very lofty.，But it's easy to use.。”Zhou He said，Orderly seedling throwing machine used for 4 years，Planting double-cropping rice is more confident.，Young people around them are more enthusiastic about farming.。This year，Zhou He planted 1500 mu of rice.，Including 1000 mu of double-cropping rice。
At present，Zoomlion Orderly Seedling Throwing Machine has been promoted more than 4000 sets.，Mainly sold to Hunan、Anhui、 Jilin 、Jiangxi and other major rice producing areas。The product has entered the test stage in the overseas market.，Is about to show its skills.。
