AI Technical Summary

Problems solved by technology

The seed is placed inaccurately relative to the ground cover, i.e. the seed is placed inaccurately relative to the fertilizer strip deposited by the fertilizer coulters
This leads to uneven accumulation of germinated seeds resulting in reduced yields

Embodiment Construction

[0030] Such as figure 1 Shown is a precision planter with frame 6, viewed from the direction of travel F, a fertilizer coulter 12 is set, a running device 14 designed as a roller 15, and a sowing coulter 7,8 designed as a double disc coulter, said The sowing coulters 7 , 8 are located on a rotatable, height-adjustable coulter arm 40 and can exert a certain pressure thereon. Behind the unitary structure is another pair of pressure rollers 56,57. A plurality of said frames 6 are connected to and laterally spaced apart from a not shown pipe frame of a precision seed drill. The fertilizer coulter 12 is a double disc coulter with a liquid or solid fertilizer discharge pipe arranged inside. The fertilizer coulter 12 can be designed to be movable relative to the running device 14, supported by spring elastically and / or adjustable in height. In addition, a sweeping device for removing residual vegetation or foreign matter is provided on the upstream side in front of the fertilizer ...

Abstract

Fertiliser drills and seed drills (13) mounted so as to swivel on drill arms (40) are arranged on the frame (6) of a pneumatic single-corn sowing machine, viewed in the direction of travel. A working implement (14) designed as a roller (15) is located between the fertiliser drills (12) and the seed drills (13) in order to reconsolidate the soil turned by the fertiliser drill (12), to precompress the soil between the working implement (14) and the seed drill (13), and to provide a depth guide for the single-corn sowing machine.

Description

technical field [0001] The present invention relates to an assembly of coulters on the frame of an agricultural machine, especially a fertilizer coulter on the frame of a planter and a double disc coulter rotatably mounted on a coulter arm, especially for a precision pneumatic seeder, Background technique [0002] Precision pneumatic seeders are used in agricultural production in order to be able to sow seeds separately and at a certain distance on the ground. European patent application number EP2374343A1 discloses a precision seed meter unit such as a precision seeder with spring-loaded fertilizer coulters upstream. The soil is picked up by the fertilizer coulters, impairing the function and depth guidance of the rear seeding coulters. The seed is placed inaccurately relative to the ground cover, ie the seed is placed inaccurately relative to the fertilizer strip deposited by the fertilizer coulters. This results in an uneven accumulation of germinated seeds resulting in...
