Description
Technical Field
The utility model relates to the technical field of agricultural machinery, concretely relates to pearl bean type peanut seeder.
Background
The peanut seed filling machine (seeder) is mainly divided into mechanical type, air suction type, air blowing type and the like according to the seed filling principle. The principle of mechanical seed filling is that seeds fall into a seed discharging groove on a rotating seed discharging wheel or a seed discharging disc under the action of self gravity, and then the seed filling process is completed; after the seed wheel or the seed plate continues to rotate and the excess seeds are scraped by the seed scraping device, the seeds are discharged from the seed groove by the gravity action of the seeds and then fall into a seed guide pipe (seed pipe) of the seeder, and then the seed discharging process is finished.
The geographical environment of the Fujian is called 'eight mountains one water one field', the mountains and hills account for more than 80% of the total area of the whole province, the peanut planting land is small in area, and large-scale mechanized operation cannot be realized. The mechanical peanut seeder is simple and compact in structure, easy to miniaturize and suitable for being used in Fujian. The Fujian belongs to the spring and autumn double-cropping peanut region in south, the planted peanut variety is mainly of pearl bean type, and the specification and the planting mode of the variety are obviously different from those of peanut regions in Huang-Huai-Hai, northeast and Yangtze river basin. The pearl bean type peanut planted in Fujian has an approximately elliptical cross section, large individual size and length difference, small grains and thin skin, and is easy to damage. The existing mechanical peanut seeder is mainly designed for large-grain and uniform-grain peanuts planted in the north, and the small-grain peanuts planted in Fujian are easy to cause multiple grains or cavities and are easy to damage; therefore, many of the mechanical peanut planters available in the north are not suitable for use in the civil engineering and even in southern hilly mountainous areas, and must be improved.
The key point of the improved design is to aim at the seed metering device of the seeder, the seed filling and seed metering performance of the seed metering device meets the requirements of the peanut seeding on the seed quantity and the seed quality, 2 seeds are planted in each hole and are not damaged (the seed metering device meets the corresponding requirements of most seeding), and the corresponding assessment performance indexes are the qualified rate of the seed quantity (1-3 seeds are qualified, 2 seeds are as large as possible) and the seed damage rate. The qualification rate of the number of holes and the seed breakage rate are closely related to the structural type and the related size of the seed discharge grooves on the seed discharge wheel, and the two indexes are usually a pair of contradiction pairs, namely the number of holes and seeds is accurate, the seed scraping effect is required to be enhanced, but the seed breakage is increased; the seed scraping effect needs to be reduced when the seed damage needs to be reduced, but the number of holes cannot be guaranteed.
