Precision corn seeder

Abstract

The invention discloses a precision corn seeder comprising a tractor, a trailer and a seeder body. The precision corn seeder is characterized in that a frame of the trailer is provided with a negativepressure extraction machine, a water pump and a water tank; the seeder body is composed of a beam, a negative pressure pipe, a water spray pipe and a plurality of seeding units; the negative pressurepipe and the water spray pipe are respectively located above and below the beam and is parallel to the beam; the negative pressure pipe is communicated with an exhaust pipe by a communication pipe and is communicated with the seeding units; the water spray pipe is communicated with a water outlet of the water pump by a water outlet pipe and is provided with a plurality of spray heads at intervals; and the plurality of seeding units are equidistantly and fixedly arranged on the beam. The precision corn seeder disclosed by the invention is capable of performing corn seeding operation under a negative pressure environment, the row spacing and the line spacing are adjustable and relatively stable, meanwhile, spray irrigation and / or fertilization operation can also be realized, very high germination and emergency rates of corns are ensured, and the problems of low efficiency and high labor intensity of artificial seeding are solved.

Description

technical field [0001] The invention relates to a corn precision seeder, more specifically, to a corn precision seeder capable of seeding under the action of suction negative pressure and capable of spraying and irrigating farmland. Background technique [0002] my country's agricultural mechanization continues to develop, and more and more manual labor links are gradually replaced by machinery, which not only liberates a large number of labor force, but also improves work efficiency and work quality. Corn is one of the main agricultural crops in my country. Its planting area is second only to rice and wheat, and it is planted in a large area in my country. In order to maintain the distance between plants and the emergence rate, the existing corn sowing is usually done manually. During the manual sowing process, the pits are first planed, then the corn kernels are placed, and finally landfilled and compacted. Two people can only sow 1 mu a day at most. The efficiency is rel...

AI Technical Summary

Problems solved by technology

It is not easy to control the plant spacing and the number of sown corn kernels of the single-row corn planter. When the corn kernels are relatively small, 3 or more seeds may be planted in a planting pit, and the excess corn seedlings need to be removed after germination , and the removal of corn seedlings must be done manually, which undoubtedly greatly increases the workload, and also produces waste of corn seedlings.
