Abstract

The invention discloses an air-aspiration type precise seeder which comprises a seeding mechanism and a seed chamber assembly, wherein the seed chamber assembly is connected with the seeding mechanism through a hinge pin and is fixed through a handle; the seeding mechanism mainly consists of a seeding mechanism support, a stirring wheel, a seeding disc, a saw tooth scraping blade, an air cutting baffle plate, a pressing cover, an air sucking chamber, a first bevel gear, a second bevel gear, a transmission shaft and an elbow which are assembled together. By adopting the air-aspiration type precise seeder disclosed by the invention, seeding in a common planting mode can be implemented, and no-tillage seeding can be also achieved on lands with complete straw mulching of a protective farming technique. Corn, soybeans and grain crops can be sown, crops such as oil sunflower and big melons can be also sown, such as peanuts, broomcorn and sunflower, and a linear equidistant single-granule seed ordering procedure can be completed at one time in operation. The purpose of accurate amounts and precise positions are achieved, and the air-aspiration type precise seeder has mechanical transmission in operation, is stable and reliable and low-carbon and environment-friendly, and is both attractive and reliable in overall structure.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to an air-suction precision seeder. Background technique [0002] At present, there are many kinds of precision seeders in the domestic market, and the differences are also very large. They are generally divided into air suction type, finger clip type, spoon wheel type and slot wheel type. The air suction type and the finger clip type are precision seeders, which are widely used in seeding operations and vigorously promoted by the country. At present, the air-suction precision seeder on the market uses a rotating sowing disc, which rubs against the air suction chamber. The problem is that the sowing body and the sowing disc are fragile, resulting in the air suction chamber not being tightly closed, and not only the sowing disc must be replaced frequently; What's more, the negative pressure chamber is not well sealed and leaks air, resulting in broken holes and missed seeding, ...
