Abstract

The invention relates to a chain type seeding machine. The chain type seeding machine comprises a drive mechanism (1), a seed filling mechanism (2) and a seeding mechanism (3). The drive mechanism (1) comprises a main chain wheel mechanism (11), an assistant chain wheel mechanism (12), a drive gear wheel (16), a drive shaft (15), a driven gear wheel (13) and a driven shaft (14). The seed filling mechanism (2) comprises a seed box (21) and a seed filing device (22). The seeding mechanism (3) comprises a scraper assembly chain belt (31), a scraper assembly (32), a seeding groove chain belt (33) and a seeding groove (34).

Description

technical field [0001] The invention belongs to the field of agricultural machinery, and in particular relates to a finger-chain seed metering device applied to a seeder. [0002] technical background [0003] At present, most of the seed metering devices used in China are composed of seed boxes, seed metering devices, and seed delivery pipes, and can be divided into pneumatic type and mechanical type according to their working principles. The pneumatic seed metering device has the advantages of strong adaptability to seeds and light damage, but its structure is complex, power consumption is large, and the cost and technical requirements are high. Although the mechanical seed metering device has low production cost and simple structure, it has strict requirements on the size of the seeds, poor adaptability to high-speed operation and high seed damage rate. The common mechanical seed metering devices in the prior art include outer groove wheel type, socket type, horizontal di...
