Description
Technical Field

Background
China has long farming culture source, and the land fertility is continuously maintained due to reasonable fertilization and proper cultivation and intermission maintenance. Recently, however, in order to increase the per mu yield level, fertilizers have been applied to agricultural fields and high-density planting has been carried out. Due to the fact that the fertilizer consumption is unreasonable, the planting mode is unscientific, the chemical fertilizer applied by sowing cannot be utilized by crops in time, the crops in partial areas cannot be sufficiently supplemented by the chemical fertilizer, and the yield per mu level cannot be improved based on reasonable close planting and scientific fertilization.
In order to solve the problems and improve the scientificity of fertilizer application, people develop some sowing and fertilizing integrated agricultural equipment, such as a layered fertilizing and deep-loosening seeder with application number of 2016100812431 and publication number of 2016, 04 and 27, and the layered fertilizing and deep-loosening seeder comprises a frame, a fan, a deep-loosening mechanism, a fertilizing mechanism, a sowing mechanism and a land wheel driving mechanism; the seeding mechanism comprises an air-blowing seed sowing device and a parallel four-bar linkage mechanism. The layered fertilization and deep scarification seeder adopts layered fertilization, can realize adjustment of fertilization amount of each layer, and can fertilize according to fertilizer requirements of crops in different growth periods. In addition, as can be understood from the overall introduction, the device adopts a combined operation mode of front-end fertilization and rear-end sowing, but the depth of deep fertilization and shallow fertilization is specific and cannot be adjusted according to specific use conditions. And the seeding mechanism and the fertilizing mechanism are integrally formed, in the seeding process, when uneven ground is met, the seeding mechanism is quickly pulled to be in a horizontal state after the rack passes over the raised ground, and the seeding mechanism is still in a stage of climbing the raised ground, so that a plough of the seeding mechanism can deeply enter the soil. The corresponding situation also occurs when passing through a concave ground, so the structure is easy to cause uneven sowing depth, and has great influence on the later sprouting and lodging resistance.
In the prior art, a driving shaft of a tractor is generally used as a power source of planting equipment, and a plurality of groups of transmission equipment are adopted to distribute power provided by the driving shaft of the tractor to a plurality of mechanism assemblies, but the driving mode easily causes that the farming equipment and the sowing equipment still idle after being lifted off the ground, thereby wasting seeds and grains.
