Light and simple type precision corn planter

Abstract

The invention belongs to the technical field of agricultural machinery, and in particular relates to a light and simple type precision corn planter. The light and simple type precision corn planter comprises a machine frame (4), a transmission mechanism (7) and a planting mechanism (9), wherein in the transmission mechanism (7), one end of a land wheel installation plate (12) is connected onto a fixed vertical beam (14) of the machine frame (4); the other end of the land wheel installation plate (12) is hinged with the axle of a transmission land wheel (10); the transmission land wheel (10) is below the front side of the machine frame (4); in the planting mechanism (9), a seed discharger (17) is connected onto a planting and trenching upright post (16); communicating seed discharging pipes are arranged between a seed box (24) and the seed discharger (17); a planting and trenching device (19) is arranged below the planting and trenching upright post (16); one end of a press wheel connection plate (21) is hinged with a press wheel (20); and the other end of the press wheel connection plate (21) is connected to an intermediate beam (23) through a planting depth adjusting mechanism (22). In the corn planter disclosed by the invention, the transmission land wheel and the press wheel are arranged at the front and the back, so that transmission is simplified; and the light and simple type precision corn planter has the advantages of being high in seed discharging precision, compact and reasonable in structure, reliable in transmission, steady to work and convenient to transport, and is applied to corn planting in a hilly area.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, and in particular relates to a light and simple precision corn planter. Background technique [0002] As the main agricultural equipment now, the seeder has a major impact on the current agricultural production. The southwestern corn area is small and scattered, with large ground elevation differences, narrow and rugged mountain roads, and transportation is more difficult than in the plains, which brings a lot of inconvenience to the mechanized sowing of corn. The drive wheel and the pressure wheel of the existing small planter are integrated. The transmission is complicated, and the transmission and suppression are unreliable in mountainous and hilly land. Contents of the invention [0003] In order to overcome the above disadvantages, the object of the present invention is to provide a light and simple precision corn planter with compact and reasonable structure, stable and re...
