Definitions

• the invention relates to a seed drill according to the preambles of claims 1 and 7.
• Such a seeder is described, for example, in the unpublished German patent application 102 28 020.
• locking and / or depth guidance channels are arranged behind the coulters, which, when viewed in plan view, are set at an opposite angle and to a V opening in the direction of travel.
• the soil materials thrown up by the coulters are returned to the sowing furrow after the seed has been deposited in the sowing furrow, so that the seed is covered with soil and a relatively flat soil surface results.
• rollers By means of these rollers, as described above, it is not possible to press the seed deposited in the seed furrow. In some cases, it is necessary to press the seed onto the water-bearing soil layer in order to give the seed optimal germination conditions.
• pressure rollers are arranged directly behind the coulter, and with it, which press the soil above the seed. Especially on moist soils, a dense and hard layer then forms during dry periods, through which the seedling of the seed cannot penetrate. The seed furrows themselves remain open grooves.
• the invention has for its object to provide good contact of the soil with the soil by simple measures and to ensure that loose soil is above the pressed seed and the pressed soil layer.
• This object is achieved according to the invention in that a roller aligned with the chisel coulter and rotatably mounted is arranged between the chisel coulter and the rollers.
• a simple attachment of the seed pressure rollers to the chisel coulter results from the fact that the seed pressure roller is attached to the chisel coulter by means of a rocker and can be loaded in the direction of the sowing furrow by means of a spring arrangement. A sufficiently secure pressing of the seed against the water-bearing layer of the soil is hereby achieved.
• the seed pressure roller can follow bumps in the ground or avoid obstacles stuck in the ground without being damaged.
• the seed pressure roller is arranged interchangeably and can be exchanged for a seed pressure roller having a different width. This allows the optimal seed pressure rollers to be used.
• An advantageous placement of the seed in the soil and optimal germination conditions of the seed can be achieved by designing the seed pressure roller in this way is that the seed deposited by the chisel coulter in the seed furrow is pressed against the soil with the soil slightly above the seed, and that after the seed has been pressed by the seed pressure roller, the V-shaped depth guide channels introduce loose soil into the seed furrow.
• the seed pressure roller with its position is arranged on the seed coulter in an easily removable manner.
• the seed pressure roller can either be attached to or removed from the coulter.
• the chisel-like tear-open element is arranged on the share body of the chisel coulter by means of an articulated spring against the direction of travel.
• the entire mass of the coulter does not have to move to an obstacle stuck in the ground when the chisel tip hits it, but only the chisel-like tear-open element itself avoids, which means that much smaller masses have to be avoided when hitting the ground avoiding stuck obstacles.
• this configuration is very easy to carry out.
• This inclined surface can be formed by the chisel-like element alone or together with its fastening parts on the share body. Due to the low moving masses of the chisel alone or the chisel together with its holder and with a slight lifting of the coulter during the lifting process, this stone protection is also suitable for the highest sawing speeds (modern tractors can pull the seeder across the field at 20 km / h) and to make it relatively inexpensive.
• An advantageous arrangement of the tension spring results from the fact that the tension spring generating the spring force is arranged upright in front of the upright front area of the share body of the chisel coulter.
• a protected arrangement of the tension spring can be achieved in that the tension spring generating the spring force is arranged to run upright within the share body of the chisel coulter.
• a simple arrangement of the tear-open element on the share body can be achieved in that the chisel-like tear element is articulated on the share body by means of tabs extending laterally of the share body.
• a tension strut is arranged between the tear-open element and the tension spring.
• the tension spring and the tension strut cannot be damaged, it is provided that the tension spring and / or the tension strut is arranged in a protected area of the share body.
• the chisel-like element is preferably arranged on the share body in an easily replaceable manner and can be easily replaced in the event of damage or wear.
• the spring can be arranged so that it can be tensioned by means of a threaded element and can be relaxed for replacement via the threaded element.
• the chisel-like element can be designed with its holder so that it can be unhooked from the share body after the spring has been released or removed.

• two locking and / or depth guide tubes 108 are arranged on the share body 102 by means of the holder 106 at an angle to the direction of travel 107 and seen in a V-shape relative to one another in plan view.
• These depth guide tubes 108 have a circumferential edge 110 which is arranged at an angle to the running surface 109 of the rollers 108 and which is designed in a serrated manner like that Drawing shows.
• rollers 108 are set to a V opening in the direction of travel 107, as already said.
• a seed pressure roller 111 which is aligned with the chisel coulter 101 and is rotatably mounted, is arranged on the bracket 113 via the rocker 112.
• the seed pressure roller 111 is attached to the chisel coulter 101 with the rocker 112 and is loaded in the direction of the sowing furrow 105 by means of the spring arrangement 114.
• the seed pressure roller 111 is arranged interchangeably and can be exchanged for a different width seed pressure roller. A wider seed pressure roller is used on firm soils than on light soils.
• the seed pressure roller 111 is designed in such a way that it presses the seed 115 deposited by the chisel coulter 101 in the seed furrow 105 with the soil slightly above the seed 114 against the soil. After the seed 115 has been pressed by the seed pressure roller 111, the V-shaped furrow closing and depth guiding tubes 108 bring loose soil into the seed furrow 105, so that a flat soil surface is created after sowing.

• a tension spring 113 is arranged, which fastens in the upper region of the share body 106 is.
• This upper fastening 114 is designed as a variable-length element so that the tension of the tension spring or its pretension can be adjusted.
• the tension spring 113 is arranged upright in front of the front upright area of the share body 106 of the chisel coulter 101 in a protected area. In the lower area, the tension strut 111 is located within a slot arranged on the share body 106.
• the chisel-like tear-open element 108 is arranged on the body 106 of the chisel coulter 101 so that it can be deflected against the spring force against the direction of travel 115 by means of the joint 109, as shown in particular in FIG. 5.
• the mode of operation of the chisel-like tear-open element 8, which is arranged in an evasive manner, is as follows:
• the chisel-like tear element 108 In the working position, the chisel-like tear element 108 is in the position shown in FIG. 3.
