Abstract

The invention relates to a near ground aviation precision seeding apparatus of spheroid small-grain-sized crops. The near ground aviation precision seeding apparatus comprises an aircraft, a seed displacement apparatus, a seed feeding and guiding apparatus and a controller, wherein the seed displacement apparatus, the seed feeding and guiding apparatus and the controller are respectively arrangedon the aircraft, the seed displacement apparatus comprises a central intensive-displacement seeding apparatus or a plurality of single seeding apparatuses which are arranged side by side, when the single seeding apparatuses are adopted, each single seeding apparatus or each seed displacement opening of the central intensive-displacement seeding apparatus can be independently started and stopped, the seed feeding and guiding apparatus comprises a plurality of seed feeding and guiding pipes, an inlet end of each seeding feeding and guiding tube is connected with a seed feeding opening of one single seeding apparatus or a seed displacement opening of the central intensive-displacement seeding apparatus. The controller is used for controlling the state of the seed feeding and guiding apparatusas well as the starting and stopping, rotation speed and acceleration of the seed displacement apparatus in the operation process. By adopting the near ground aviation precision seeding apparatus, the seeding system can be controlled to precisely sow the seed according to the position and speed information of the aircraft. The near ground aviation precision seeding apparatus is particularly suitable for planting creative landscape crops requiring a pattern molding effect.

Description

technical field

[0001] The invention belongs to the technical field of agricultural and forestry machinery, and relates to a near-ground aerial precision sowing device for seed crops with spherical small particle diameters. Background technique

[0002] In recent years, my country's creative landscape agriculture has made great progress. For the development of tourist attractions and the needs of advertising, people hope that the crops in the farmland can not only increase their yield and increase their income, but also show a certain visual effect of calligraphy and painting landscape modeling during their growth period, so as to achieve the purpose of creating an environment and wide publicity. Due to the strict precision requirements of the pattern boundary, it is difficult for ground machines to complete the task at this stage, and people can only use purely manual methods for shape design and construction. This method is time-consuming and labor-intensive and has a hig...
