Corn harvesting machine

Abstract

The invention discloses a corn harvesting machine. The corn harvesting machine comprises a rack, a traction frame, a spiral ridge flattening device, a sowing device, a fertilizing device, a transmission device, a rotary tillage device, a film coating device, a soil lifting and covering device, a land wheel and a ridge flattening roll flange. The corn harvesting machine can finish multiple work links of rotary ridge flattening, surface layer soil rotary tillage side deep fertilizing, seedbed shaping, film coating, precise amount pit sowing, seedling strip soil covering on film and the like at one time. Sowing is precise, seedling releasing and weeding are not needed, the problem that corn planting is insufficient in accumulated temperature is solved by film coating, the problem of insufficient density is solved by big ridge cultivation, furrows are lifted and preserved, shaping and soil covering on the ridge make the seedling strip ponding effect remarkable, the problems that directly sowed corn is difficult in seedling emergence, low in emergence rate in a spring drought year and poor in growth vigor are effectively solved, weed spreading is effectively inhibited, staggered precise sowing in the big ridge with double lines of wide and narrow lines is beneficial to ventilation and light transmittance, film coating increases the water temperature, ground temperature and fertilizer utilization rate, the land blocks worked through the corn harvesting machine has neat and strong seedlings, and the yield increasing effect is remarkable.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a corn harvester. Background technique [0002] Corn is the main crop in our country, and it is a crop with a relatively large sowing area. Due to the special situation of a large population and little land in our country, people are trying to improve the utilization rate of the land, increase the yield and quality per unit area, and increase farmers' production and income. . However, the conventional planting of corn in northern my country has been affected by insufficient accumulated temperature, insufficient water, and insufficient seedling preservation rate for a long time. The procedures are complicated and the labor intensity is high. After the film is covered, the seedlings need to be released. If the seedlings are not released in time, the phenomenon of seedling burning may occur, which not only increases the production cost but also affects the output. Du...

Problems solved by technology

However, the conventional planting of corn in northern my country has been affected by insufficient accumulated temperature, insufficient water, and insufficient seedling preservation rate for a long time. The procedures are complicated and labor-intensive. After covering the film, the seedlings need to be released. If the seedlings are not released in time, the phenomenon of seedling burning may occur, which not only increases the production cost but also affects the output.

Due to lack of water and low fertilizer utilization rate in spring drought areas, it is difficult to grow full seedlings, and it is impossible to increase production and income. With the acceleration of industrial pace, the contradiction of labor resource shortage has become more and more prominent. Traditional corn planting requires more labor and consumes more energy. The production methods with high and low output and serious damage to the ecological environment are increasingly encountering obvious resistance to development. Therefore, research and development of a worry-free, light, low-consumption, high-efficiency agriculture and a labor-saving, water-saving, Fertilizer-saving, drug-saving, temperature-increasing, cost-saving and efficient corn planting methods have become the inevitable direction of modern agricultural development, and are also the urgent desire of farmers
