Jiinzeikorn -. Flaking device

The invention relates to a single-grain planting device especially for mechanical beet single grain sowing.

Nowadays, special devices are mainly used for each type of fruit - for example, the sowing of beets and maize. The seeding mechanism is the actual "heart" of the precision seeder. Depending on which filling principle is used, a distinction is made between mechanical and pneumatic sowing systems. According to "Die Landwirtschaft""Landtechnik - Bauwesen" Volume 3 BLV Verlagsgesellschaft mbH, Munich, 1973 Page 242 a mechanical single grain seeder is known, in which the same mechanism underg -Λ rächte in a cast housing consists of a separate cell and chamber wheel. The grains are picked up from the seed supply by the ZeI-Lanwheel, conveyed upwards and transferred to the associated chamber of the chamber wheel. This transports the grains downwards, where they are released into the seed furrow with a drop of just under 3 cm. This construction ensures that even at high driving speeds (6-8 km / h) at the moment of grain delivery, the "relative speed" between the seed grain and the soil is zero and the grain cannot roll in the seed furrow. -

A groove in which the planting cylinders end is expediently located on the circumference of the impeller.

When the impeller revolves, the peripheral Rut half closed by a wire, each of which covers the openings of three seed cylinders.

The wire is expediently attached to the housing of the planting device with a holder.

The ends of the planting pistons in the seed cylinders are advantageous conically turned off.

The principle of the seeding mechanism with punched strips and cellular wheels, Chamber and bucket wheels come in many variations known.

In this sowing process, the sowing unit generally exists from clod clearer, pressure roller, seed coulter, cell wheel, scraper for surplus grains ^ pressure roller for firm Embed the seeds and fillers.

The invention is based on the object of simplifying the sowing unit by reducing the number of sowing devices, and one to achieve particularly precise grain placement in terms of depth and distance as well as low soil coverage.

This object is achieved according to the invention in that an impeller is used with six seed cylinders arranged in a rotationally symmetrical radial manner over the circumference,

in which six planting piston against the pressure of _spiral;!

feathers work between the sliders and the plant f

pistons are arranged, the planting pistons from a | i

eccentric disk arranged centrally in the impeller with g

operated by means of push rods mounted on rollers, |

which are guided in the slides and against the ends fi

press the planter rods. |

With this single-grain planting device there is none Coulter required; for the grain comes from the Single-grain plant cylinders at a constant distance pressed against or into the ground, the weight of the wheel running on the ground causing this impresses enough. This means that the entire single-grain planting device can consist exclusively of clod clearers and assemble the seed wheel with the seed hopper.

In the drawing, an embodiment of the single-grain planting device is shown. Show in it:

Planting cylinders and

Figure 2 is a section in the direction A-B of

Figure 1.

In the drawing, the impeller is denoted by 1, in the center of which the eccentric 6 is located. On the circumference of the impeller 1, six planting cylinders 4 are arranged in a rotationally symmetrical manner. In the planting cylinders 4, six planting flasks 2 work against the pressure of spiral springs 3. These lie on the one hand on the planting flasks 2 and, on the other hand, on the slides 5 ₅ through which the piston rods of the planting flasks 2 are guided. In the slides 5, the piston rods abut with their ends against six eccentric push rods. The planting flasks are actuated by the fact that the abutting push rods rotate on ball bearings in the eccentric 6 of the impeller 1.

When the wheel 1 revolves around the eccentric disk 6 describe the push rods a simple spiral path - they are withdrawn towards the center of the eccentric and jump back to the starting position after one revolution -. This will make the planters in the slides 5 from the abutting push rods

by means of springs 3 advanced and brought back.

The circumference of the impeller 1 and the planting cylinder ending therein are provided with a groove in which

A wire 7, which is provided with a holder 8, lies over half the circumference of the wheel. In this part of the groove and the ^z ylinderöffnungen are closed by the wire. 7 The stroke of the push rods and thus the planting flask 2 between the beginning and the end of the eccentric causes the planting flasks in the planting cylinders 4 to be withdrawn and - when the respective eccentric push rod is moved into the starting position - to snap forward to the circumference of the impeller. The Pflanzkol- \ ben 2 are off tapered for this purpose at its head

turned. When the impeller 1 moves over the bottom and the opening of the plant cylinder 4- am, you press End of the wire 7 in the peripheral groove of the wheel 1 the grain in the planting cylinder 4- in or on the Floor. The impeller 1 is pulled over the ground in the direction that the planting cylinder emptied during sowing is open revolves up to the seed container, not shown, the planting flask with the eccentric poking rod is withdrawn.

After taking up a seed, the respective planting cylinder is 4- through wire 7 in the groove of the barrel

\ 25 rades 1 closed, which also serves as a scraper.
