High-density precise dibbler

Abstract

The invention relates to a high-density precise dibbler which comprises a fixed shaft, a seed chamber outer shell fixed on the fixed shaft, and a retaining plate rotationally connected on the fixed shaft; a floating separating plate is arranged between the seed chamber outer shell and the retaining plate; a plurality of seed guiding slots uniformly distributed around the axis of the fixed shaft are fixed between the floating separating plate and the retaining plate; the high-density precise dibbler also includes a seed taking mechanism; the seed taking mechanism is fixed on the retaining plate and above the floating separating plate; one duckbill combination body is fixed at a position, far away from the end part of the fixed shaft, of each seed guiding slot and is used for sowing seeds into soil. The high-density precise dibbler has the beneficial effects of high-density sowing realization, simple structure and low manufacturing and assembly costs; a process of the seeds rolling from a seed chamber to the duckbill combination bodies is smooth and has no seed clamping; precise sowing is realized, adjustment of the seed taking quantity is convenient, and no tools are required; and the duckbill combination bodies easily penetrate into the soil and pierce a mulching film, to ensure smooth sowing and the seed germination rate.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a high-density and precision hole seeder. Background technique [0002] With the development of modern agricultural technology, precision seeding has become a development trend, especially precision seeding under high-density planting mode is also widely used in agricultural production. [0003] At present, there are mainly two ways of precision sowing: on-demand (hole sowing) and drill sowing. Drilling is mainly to discharge seeds evenly through the seed metering device, and then freely fall into the ditch. The fallen seeds are prone to displacement during the falling process and after falling in the ditch, which affects the uniformity of the seed distance. Since high-density precision seeding often requires the seed distance to be accurate to centimeters, the drilling method is seldom used due to its low positioning accuracy. [0004] Therefore, the further den...

Problems solved by technology

[0006] Due to the limitation of the structure, the current wheel-type on-demand mechanism has reached the limit when the seed distance is small to a certain extent, and it is difficult to further reduce the distance.

For example, the minimum planting distance of the current cotton on-demand device is generally about 10 centimeters, and it is very difficult to
