Abstract

The invention belongs to the technical field of agricultural machinery, provides a precise seed-metering device of the agricultural machinery and in particular relates to a waterwheel type single-seedprecise seed-metering device. The waterwheel type single-seed precise seed-metering device comprises a seed basin arranged at the bottom, a seed-metering device distributed above the seed basin and aguide rail distributed at the front part of the seed-metering device. By adopting the waterwheel type single-seed precise seed-metering device, seed filling and metering of a plurality of rows can realized in one step; a special hole spoon design is adopted so that single-seed seed filling is realized and surplus seeds are removed by gravity; under the action of an overturning mechanism, low-level seed metering is realized, seed falling caused by vibration is reduced and the voiding rate is reduced.

Description

technical field [0001] The invention relates to a water wheel type single seed precision metering device, in particular to a device for precise rice metering of agricultural machinery, and belongs to the technical field of agricultural machinery. Background technique [0002] Precision seeding is one of the key technologies to realize precision seeding. my country began to research and promote precision seeding technology in the 1970s, but it has not been widely used so far. The main reason is that there are no suitable precision seeding components. In recent years, there have been many studies on single-grain precision seed metering devices. For soybeans, corn and other round or nearly round-shaped regular seeds, single-grain precision seeding can basically be achieved. However, for most non-circular seeds, the filling process is extremely complicated, and it is still difficult to achieve single-seed precision seeding technology. In terms of agronomy, with the continuous d...
