Indented wheel special-shaped hole precision seeding device for broad beans

Abstract

The invention relates to an indented wheel special-shaped hole precision seeding device for broad beans and belongs to the technical field of agricultural machinery. The indented wheel special-shaped hole precision seeding device for broad beans comprises a frame (1), a seed metering device (2), a ditching and soil covering assembly (3), a motor (5), a speed reducer (6), walking wheels (7), a press wheel (8), and a sprocket drive mechanism I (9). Seeding wheels and seed cleaning wheels cooperate to work, such that a re-seeding condition can be avoided as much as possible, meanwhile, seed cleaning slopes are arranged in seed metering holes of seed metering wheels, such that resistance of the seed cleaning wheels to seeds in a seed cleaning process can be reduced, and a damage rate of the seeds is reduced. The indented wheel special-shaped hole precision seeding device replaces manual broad bean sowing, realizes consistent plant spacing and row spacing and uniform depth during the sowing, reduces labor intensity of farmers and a production cost, and meanwhile improves an operation speed during the broad bean sowing.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, and in particular relates to a precision sowing device for fava beans with special-shaped holes and socket wheels. Background technique [0002] Due to the high nutritional value of broad beans, the large-scale planting areas of broad beans in China are mainly distributed in autumn sowing areas such as Yunnan, Sichuan, and Hubei (accounting for about 90% of the national broad bean planting area) and spring sowing areas such as Gansu, Qinghai, and Ningxia (accounting for the national total). 10% of the broad bean acreage). [0003] However, at present, most of broad beans adopt the backward planting method of artificial on-demand planting, which has low level of mechanization, high labor intensity and high production cost, which seriously hinders the development of broad bean industry. Contents of the invention [0004] In order to solve the problems raised in the background tech...
