Corn minimal tillage combined machine

Abstract

The invention relates to the field of corn planting, in particular to a corn minimal tillage combined machine which comprises a main frame body, minimal tillage cutters, a power gearbox and a layereddeep fertilizer applicator. The power gearbox is arranged in the main frame body, the minimal tillage cutters are arranged on output shafts at the two sides of the power gearbox, and the main frame body is connected with a tractor frame body through a suspension frame; and a power input shaft of the power gearbox is connected with a power system of a tractor through a universal joint transmissionshaft, a connecting frame is arranged at the rear end of the main frame body, the front end of a seeder is installed on the connecting frame, and an angle-adjustable layered deep fertilizer applicatoris arranged at the lower end of the connecting frame. The corn minimal tillage combined machine can effectively break through a hard ploughing layer while completing corn seeding operation at a time,corn can absorb moisture and nutrients of deep soil, multi-layer tower type three-dimensional fertilization can also meet the nutrient requirements of the corn in all growth stages from the seedlingstage to the mature stage, corn kernels are particularly full, and the yield is greatly increased.

Description

technical field [0001] The invention relates to the field of corn planting, in particular to a combined less-tillage operation machine for corn. Background technique [0002] Corn is the main food crop in my country. With the improvement of my country's agricultural production level, higher requirements are put forward for corn production. In the current corn production process, the proposal of the "seven-point planting and three-point management" measure obviously pays attention to the requirements of corn sowing. If this link is mastered, the corn yield can basically be guaranteed. "Seven-point planting" mainly includes sowing specifications, soil Cultivation requirements, fertilizer and nutrient inputs, etc. The existing production habits are combined mechanical harvesting of wheat, straw throwing to cover the soil surface, no-tillage sowing, mechanical single-grain single-row sowing of corn or to ensure full seedling multi-grain sowing and then thinning seedlings, seedi...

Problems solved by technology

[0003] From the perspective of the current corn sowing process, machinery is involved in basically every link, but there are many unreasonable places in the process, such as the influence of the compactness and flatness of the soil in the field, and the different planting depths of mechanical no-tillage, which affect the emergence of seedlings. uniformity, while the long-term soil rotary tillage operation of the last stubble wheat leads to a shallower plow layer, which is not conducive to the absorption of deep soil nutrients by the root system of corn seeds, and may also cause late lodging. In addition, due to the shortage of agricultural labor force, ordinary compound fertilizer " The phenomenon of not topdressing fertilizer in the late stage of "one shot" fertilization has become the mainstream, while the early stage of "one shot" fertilization tends to cause excessive growth and poor stress resistance of seedlings, and early defertilization in the later stage, prone to yellow bottom leaves of corn and corn baldness. In addition, the most important factor affecting corn yield is density, but blindly increasing the density will increase the premature senescence of the group canopy, the productivity of a single plant will decrease, and it will also lead to excessive consumption of mechanical power
