Embodiment Construction

[0030] figure 1 Shown is a side view of the unit which is important for the invention, said unit comprising a sowing coulter supported on a coulter arm 40 and designed as a double disc coulter 7 which rotates about a wheel axle 36 , the unit also includes a depth control wheel 9 arranged flush. In front of the unit comprising the double disc coulters 7, 8 and the depth control wheel 9, it can be seen that the frame 6 is provided with a device 14 designed as a cylinder 15, and behind the unit is a pressure roller 57.

[0031] Such as figure 2 Shown is an overall view from the bottom up, with the direction of travel F indicated, including a view of the transition between the fertilizer coulters 12 and the cylinder 15 . In order to ensure a mutual cleaning effect and avoid soil accumulation as much as possible, the cylinder 15 has a central recess 52 for receiving the rear end 53 of the fertilizer coulter 12 . Rings 41 , 42 are provided on both sides of the recess 52 . Seen ...

Abstract

At least one set of a double-disc ploughshare (7, 8) and one depth-guide roller (9) is arranged on the frame (6) of a pneumatic precision seeder. Said depth-guide roller (9) is arranged between the two disc ploughshares (7, 8) when viewed in the direction of travel and both ploughshares (7, 8) and the depth-guide roller (9) rotate in the same direction.

Description

technical field [0001] The present invention relates to an assembly of coulters on the frame of an agricultural machine, especially a double disc coulter and a depth control wheel assembly on the frame of a seeder, 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. The assembly of a double-disc coulter is known from DE102007011297, where a subassembly mounted separately on the machine frame runs behind the double-disc coulter. The subassembly includes a depth control wheel and two pressure rollers located at opposite rears on either side of the depth control wheel. The pressure rollers are mounted together with the depth control wheels on the machine frame. The double disc coulters and the depth control wheel rotate in opposite directions, which means that the coulters push the soil in, causing unavoida...
