Circular-disc type precision drill seeding device of small-seed crops

Abstract

The invention provides a circular-disc type precision drill seeding device of small-seed crops. The device comprises a bracket, a front roller, a rear roller, a plurality of seeding mechanisms and an engine, wherein each seeding mechanism comprises a sleeve, a seeding box for containing seeds and a seeding box case; a furrow opener is arranged at the lower end of each sleeve, and the upper end of each sleeve is fixedly connected with the corresponding seeding box case; a case opening penetrating through the sleeve is formed in each seeding box case; the bracket is further provided with fixed connecting rods for connecting the sleeves; each seeding box is of a round structure formed by a first sector-shaped seeding disc and a second sector-shaped seeding disc, which are in butt joint; seed discharging holes are formed in the outer peripheries of the first sector-shaped seeding discs; one side face of each first sector-shaped seeding disc and one side face of each second sector-shaped seeding disc, which are arranged adjacently, are sealed; the other side faces, which are arranged adjacently, of each first sector-shaped seeding disc and each second sector-shaped seeding disc are communicated with each other; seeds passing through the seed discharging holes drop off from the case openings and fall into seed furrows opened by the furrow openers through the sleeves. When the device is used for seeding, the device does not slip and has a good compaction effect, and a precision seeding effect with less thinning is realized.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a disc-type precision drill device for small-grain crops suitable for millet, millet, radish, cabbage, soybean and other crops. Background technique [0002] Millet, millet, millet and other small-grain miscellaneous grain crops have the characteristics of drought resistance, barren tolerance, strong adaptability, and rich nutrition. They are also my country's characteristic and advantageous export crops, and play an important role in agriculture in arid and semi-arid regions of the world. The development of modern miscellaneous grains industry is an important way for farmers to increase their income and get rich, and for the country to alleviate poverty. [0003] If traditional columbine seeding and simple single-leg drill machinery are used, the amount of seeding is large, the seeding efficiency is low, the seedlings are difficult to thin out, the workload is larg...
