The invention belongs to agricultural machinery and particularly relates to a precise corn seed metering device. The precise corn seed metering device comprises a movable disc of a seed taking device, a fixed disc of the seed taking device, a side protection plate of the seed metering device, duckbill dibblers and a duckbill mounting frame. The precise corn seed metering device is characterized in that the movable disc of the seed taking device is of an annular body structure and is fixedly mounted in the duckbill mounting frame; the fixed disc of the seed taking device comprises a seed cavity and a seed metering channel; the seed cavity is of a sector-shaped cavity structure and is located at one side of the fixed disc of the seed taking device; the seed metering channel is of a strip-shaped cavity structure and is located at the other side of the fixed disc of the seed taking device; the duckbill mounting frame is provided with seed metering openings; the outer wall of the duckbill mounting frame is fixedly provided with the duckbill dibblers; the seed metering openings in the duckbill mounting frame are communicated with seed taking openings of the duckbill dibblers. The precise corn seed metering device is simple in structure and convenient to assemble; hill spacing is simple to adjust and the power consumption is small; the sowing precision is not limited by the sizes of seeds and the sowing precision of each single seed can be completely guaranteed.
Description
Technical field: [0001] The invention belongs to agricultural machinery, in particular to a corn precision metering device. Background technique: [0002] The seed meter is the core component of the seeder, and its working performance directly affects the quality of corn machine sowing. At present, the widely used seed metering devices on the market include the spoon wheel type seed metering device and the duckbill type seed metering device, and their sowing accuracy basically meets the agronomic requirements. The structure is complex, the power consumption is large, the adjustment and maintenance require professional operation, and it is difficult to adjust the distance between holes when sowing. The sowing accuracy is easily limited by the size of the seeds, and it is easy to cause missed sowing and multi-grain seeding. Invention content: [0003] In view of the above problems, the object of the present invention is to provide a kind of corn precision seeding with simpl...
