The invention relates to a component on an agricultural sowing machine, in particular to an air cavity rolling type precision bunch planting device applicable to a precision sowing machine. The bunch planting device provided by the invention mainly comprises a bunch planting roller (1), a lamination wheel (2) and a negative pressure seed acquiring device body (18), wherein the bunch planting roller (1), the lamination wheel (2), the negative pressure seed acquiring device body (18) and a roller spindle (6) are connected by virtue of bearings, the lamination wheel (2) is fixedly connected with the negative pressure seed acquiring device body (18) by virtue of a reinforcing plate (3) fixedly connected with the lamination wheel (2) or is directly fixedly connected with the negative pressure seed acquiring device body (18) by virtue of a connecting piece, and a gas check block (27) fixedly connected with the roller spindle (6) is arranged in the negative pressure seed acquiring device body (18). The bunch planting device provided by the invention has the advantages that: negative pressure cavity rotation and slide block gas check are combined to realize precision sowing, a negative pressure cavity has good impermeability, thus a negative pressure is more stable, air leakage of the negative pressure cavity is reduced, the seed acquiring rate is improved, and the cavity rate is reduced; and the sowing speed can be obviously improved.
Description
technical field [0001] The invention relates to a component on an agricultural seeder, in particular to an air cavity rolling precision hole sowing device, which is suitable for use on a precision seeder. technical background [0002] At present, with the continuous and in-depth development of precision agriculture, precision sowing agricultural machinery as the sowing link in precision agriculture has also accelerated the pace of modernization of agricultural machinery. Especially a kind of precision hole sowing machine, due to the need of expensive fine seeds and precision agronomy, new technologies of this machine have emerged in recent years, and new products have been released continuously, such as air suction precision seeder and air suction membrane precision seeder The hole seeder has been more and more widely used in precision seeding operations in our country. It can perform precise precision seeding on corn, sunflower, seed melon, watermelon, cotton, sugar beet, p...
