Furrowing machine with soil screening device

Abstract

The invention belongs to the technical field of agricultural machinery and in particular relates to a furrowing machine with a soil screening device. The furrowing machine with the soil screening device comprises a soil-covering and furrowing mechanism, a ground wheel mechanism and a driving mechanism which are mounted on a rack, wherein the soil-covering and furrowing mechanism comprises a furrowing mechanism and a soil covering mechanism; the furrowing mechanism comprises a furrowing machine main plate in the middle and two furrowing machine side plates arranged on two sides and is welded on the rack by virtue of a furrowing machine bracket and a furrowing machine fixing plate; an eccentric shaft and an eccentric block are mounted on the soil covering mechanism; a screen plate and a soil receiving cup are hung on the eccentric block; a soil covering tank is welded to the back of a seed metering tank and is in pipeline connection with the soil receiving cup; the furrowing mechanism is used for furrowing and simultaneously conveying the soil into the soil receiving cup and also carrying out soil covering operation. By virtue of the furrowing machine with the soil screening device, the common seed-drying problem of seeders during seeding can be solved; the furrowing machine is capable of furrowing, seeding and covering soil at one time during working; the furrowing machine is high in soil covering effect and simple in machine structure; the problem that the yield of crops is reduced due to seed drying an be effectively solved.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, in particular to a trench opener with a soil screening device. Background technique [0002] The sowing link is an indispensable link in agricultural operations, and the quality of sowing affects subsequent crop growth, which in turn affects crop yields. The phenomenon of drying seeds is particularly common in the sowing process. After sowing, the soil coverage is not standardized, and the seeding depth fluctuates greatly. If it is too deep, it will not be easy to emerge. If it is too shallow, the phenomenon of drying will occur, resulting in uneven emergence, affecting crop yields and reducing farmers’ income. In the past, in order to solve this problem, there were many special soil covering devices on the planter. There is a surface finishing mechanism behind the seeder, and the soil-covering beam in the surface finishing mechanism completes the soil-covering operation. The com...
