Pneumatic rice precision dry direct seeding machine that simultaneously realizes fertilization and level ground by opening ditch

Abstract

The invention discloses a pneumatic type rice precision dry direct sowing machine capable of synchronously realizing ditch opening, fertilization and ground flattening. The machine is divided into two parts, namely a main body part and a hanging part; the machine comprises nine units, namely a ditch opening unit, a ground flattening unit, a main rack, a fertilization unit, an air-pressure unit, a secondary rack, a land wheel system, a sowing system and an earth covering and suppression unit; a rice precision pneumatic type seed-metering device capable of sucking seeds by negative pressure and cleaning seeds by positive pressure is carried, a mini-type ditch opening plough is used for opening a ditch and front and back spiral blades are matched to flatten the ground; meanwhile, deep fertilization of a base fertilizer and soil covering are realized; a hanging type single body sowing mechanism is used for realizing anywhere profiling; functions of flattening the ground, opening the fertilizer ditch, deeply fertilizing on the lower side, opening the ditch, opening seed ditches, sowing seeds, covering the soil and suppressing can be realized on a primarily-prepared dry land; rice planting procedures and the labor intensity can be effectively reduced and the effects of saving cost and synergizing are realized.

Description

technical field [0001] The invention relates to the technical field of sowing in agricultural machinery, in particular to a pneumatic rice precision dry direct seeding machine for synchronously realizing fertilization and leveling by opening ditches. Background technique [0002] Rice is one of the most important food crops in my country, and stabilizing and improving the comprehensive production capacity of rice is an important measure to ensure food security. In recent years, due to the development of urbanization, the transfer of rural labor force and the improvement of farmers' living standards, the rice planting area has decreased year by year. Therefore, simplifying the rice planting process and improving the mechanization level of rice production are of great significance for ensuring food security. The difficulty in improving the mechanization level of rice production lies in improving the mechanization of planting. At present, the level of mechanization of rice pla...

Problems solved by technology

[0003] The existing rice direct seeding machines all use mechanical seed metering devices, which use rigid grooved wheels to scrape the seeds, which is easy to damage the seeds; in addition, the existing direct seeding machines mainly use full rotary tillage to achieve the leveling function , but this is equivalent to adding a rotary tiller in front of the live broadcast machine, the quality of the whole machine is greatly increased, and it is necessary to equip the rotary tiller with a high-power tractor; at the same time, the existing live broadcast machine does not use terrain imitation design, resulting in The consistency of the sowing depth is not good, which affects the emergence of rice in the later stage; and most of the rice dry direct seeding machines do not have the integrated ditch opening function, which leads to the need for tractors to mount ditch machines and other machines to go to the field many times, which will compact the soil and affect the rice. to grow
