Description

A kind of adaptive dependent variable no-tillage seeding control system of spacing in the rows based on Beidou observing and controlling
Technical field
The invention belongs to agricultural machinery technological fields, and in particular to one kind is high-efficient, structure is simple and the spacing in the rows of sowing can The adaptive dependent variable no-tillage seeding control system of the self-reacting a kind of spacing in the rows based on Beidou observing and controlling of speed walked according to equipment.
Background technique
With the continuous development of Tendency of Agricultural Machinery in China, Mechanization sowing is almost instead of traditional seeding operation, and essence is measured The quality of seeding quality is related to the number of the yield of cereal crops.Country's seeder is mostly ground wheel drive operation at present, and Slip rate is higher to be easy to produce slippage problems there are serious unstability to land wheel due to being influenced by ground surface environment, so that There is broadcast leakage or the non-uniform problem of spacing in the rows.
Summary of the invention
The purpose of the present invention is to provide a kind of adaptive dependent variable no-tillage seeding control system of spacing in the rows based on Beidou observing and controlling, It is passed by information such as the travel speed of Beidou navigation movement station acquisition seeder and position coordinates, and by its information by 485 buses It is sent to programmable controller, the information that the data and Beidou navigation movement station that programmable controller is inputted according to touch screen acquire, Servo stepless transmission after from processing to termination box sends instruction, and servo buncher is controlled by the size of the electric current The revolving speed of servo motor and then the revolving speed for changing discharge plate, to achieve the purpose that the adaptive quantity-variation type seeding of spacing in the rows.The invention is certainly Dynamicization degree is high, is tested the speed using Beidou navigation come the uniformity for adjusting the revolving speed of discharge plate to ensure sowing spacing in the rows, and its The parameters such as mu application rate, line-spacing and dose can be inputted by touch screen come macroscopical adjusting.
The technical solution of the present invention is as follows: the adaptive dependent variable no-tillage seeding control system of spacing in the rows based on Beidou observing and controlling, including Beidou navigation base station, Beidou navigation movement station, programmable controller, touch screen, servo buncher, servo motor and sowing Monomer；Wherein Beidou navigation movement station is mounted on tractor, is connect by 485 buses with programmable controller；Touch screen position In being connect also by 485 buses with programmable controller in tractor driving room；Programmable controller is located in control cabinet, control Case is mounted in the rack of seeder front end, and programmable controller output end is electrodeless by 485 buses and the servo in termination box Speed changer is connected, and termination box is located at planter upper end, and servo buncher controls servo by changing the size of electric current The revolving speed of motor, servo motor drives the rotation of discharge plate by chain conveyer, to realize the adaptive quantity-variation type seeding of spacing in the rows.
