Description
Technical Field
The invention relates to the field of agricultural machinery, in particular to a corn-bean dual-purpose seed cavity spray irrigation micro-compaction seeding monomer.
Background
The soybeans and the corns belong to dry-farming grain and oil crops which are planted in a no-tillage precision mode under a protective cultivation mode, and the no-tillage direct seeding planting procedures are the same, and straw treatment, ditching, fertilization, sowing, earthing, compacting and the like are all needed. Sowing is one of key links in the agricultural production process, and has a direct relation to stable yield and yield increase of crops. The quality of the bed reconstruction directly affects the uniformity of the spatial distribution of the seed soil. Studies have shown that: to obtain good seed distribution space in soil, providing orderly and stable seed flow is only a necessary condition, and bouncing rolling after the seeds land on the soil is also an important factor affecting the space ectopic distribution of the seed soil. Therefore, how to develop the advanced and proper soybean and corn dual-purpose seed bed reconstruction technology and device under the working condition of no-tillage high-speed close planting and sowing with small bouncing and rolling degree and even distribution of the space between seeds and soil after the seeds touch the soil is of great significance in promoting the development of the mechanized sowing level of the strip-shaped composite planting.
The no-tillage planting seed bed reconstruction comprises the treatments of seed belt straw cleaning, seed ditch construction, soil covering and compacting and the like. Practice shows that: bouncing or rolling of closely planted seeds after soil contact significantly affects the dislocation distribution of seed space, and secondary 'contact collision' generated by under-constrained steady-state seeds at the bottom of a ditch and heterogeneous soil return particle flow is an important reason for aggravating the dislocation of seed space. At present, the traditional furrow opener design theory is based on inverse kinematics solution of a series mechanism, emphasis is placed on mechanism innovation and structure optimization, physical attribute differences such as furrow bottom soil humidity, granularity, damping and the like are not considered, the random change of seed-soil contact pose, dynamic elastic modulus and damping ratio lacks adjustment capability, and the soil-seed contact coupling relation lacks a characterization method for migration of soil moisture to seed germination.
At present, the development of the intelligent corn seeding monomer machine is mature, but the combination of the reconstruction of a seeding seed bed and the agriculture of an agricultural machine is less. The current used seeding monomer cannot effectively interfere with the jump ectopic position of the seed flow and the seed bed after soil contact.
