Description

GERMAN

Machine tools are used for dressing seeds Saatbeizgeräte known in which a weighed amount of seed by a set in a continuous sequence The amount of pickling agent is pickled in a rotating drum. The pickling agent is supplied by a pump conveyed in a receiving container with overflow in continuous circulation and in the removal container on kept at the same level.

The supply of the liquid dressing agent to a certain amount of seed is carried out in the known seed dressing devices not exactly ·· adhered to because of the dosage has large tolerances.

According to the invention "should be a certain amount of seed a very specific amount of pickling agent can be added with the lowest tolerance. For this purpose, im Removal container for the pickling agent below the pickling agent level in a housing that is open at the top an open, raised or lowered Edge, if necessary with one attached to the jland Flange, in its lowest position rests against a seal of the housing in a sealing manner and with its upper front edge of the pickling agent inlet edge about the level; can be lifted, whereby the dosing cylinder, when lifting above the level, has a drainage Releases opening in the housing. It can be quite a certain adjustable amount of Öeizmittel each of the weighed amount of seed are fed.

According to the invention, the metering cylinder is primarily mechanically operated by means of a bracket or the like against ^ gtj the force of a spring is raised, and the spring also brings the dosing cylinder to its lowest position back again. The dosing cylinder is guided in its housing with one or more seals. A closed connector of the housing advantageously protrudes into the lower part of the metering cylinder into, the cross-section of which corresponds to the cavity cross-section of the dosing cylinder. The stub is provided with a threaded opening or similar means to allow it into the cavity of the dosing cylinder different inserts can be used to change the content of the dosing cylinder can.

Finally, there is a baffle in the extraction container between the pump inlet and the overflow Calming of the pickling agent provided. Depending on the size of the removal container, several can also be used Baffles are present.

In the drawing, the subject matter of the invention is shown in an exemplary embodiment. It shows

The well-known seed dressing device consists of a rotating one Drum 1, into which · the seed.vo »a silo the line 2 and a lappbarenfjposier.tin ^ b ^ Iil.lter 3 is inserted / as soon as the dosing tank 3 is filled is, this tips the seed in the direction of fall 4 in; fl'Än Kana ^ M, so that it gets into the drum 1, in order to migrate into a sack 7 or other container at the outlet 6 after the drum has passed through. The dosing device 3 pivots about the axis 8 and is adjustable by means of a weight 9. For each dosed Seed quantities are fed from the removal container 10 via line 11 to the drum 1.

The removal container 10 is filled with the liquid pickling agent by a pump 12 via the line 13, which can run through an overflow line 14 again when a certain liquid level is reached. In this way, the same liquid level is always maintained in the removal container 10. The dosed The amount of dressing agent is fed to line 11 via line 15 and, if necessary, a measuring container 16.

The task of the invention consists in the exact adherence to the dosed amount of dressing agent for which Purpose according to Fig. 3 in the removal container 10 below the dressing level in an upwardly open Housing 17 an open metering cylinder 18 is guided, which can be raised and lowered. The raising and lowering of the cylinder 18 takes place via the shaft 19, which in the rhythm of the metering device 3 for the seed

is moved well. In Fig. 1 it is shown that of the shaft 8 via the linkage 20, the shaft 19 in the removal container 10 each after the pivoting of the Dosing device 3 is rotated.

The dosing cylinder 18 is under the force of a spring 21, which strives to him in its deepest To hold position. The lower front edge 22 of the metering cylinder 18 lies against a seal 23 of the housing 17 in its lowest position. As soon as the cylinder 18 via the shaft 19 or a similar Mechanics is raised above the level of the pickling agent, i.e. when the upper face of the pickling agent inlet edge 24 is above the liquid level, the metering cylinder 18 is a drain opening 25 in the Housing 17 free, whereby the pickling agent can get into line 15 and then into line 11. That The liquid level in the removal container 10 is always kept at the same level by the overflow 26. Between the pump inlet 13 and the overflow 26 baffles 27 are provided to the liquid in the Calm container.

A closed cylinder protrudes into the metering cylinder 18 Stub 28 of the housing 17, the cross section of which corresponds to the cavity cross section of the metering cylinder. The connection piece is Winding opening 29 for inserting inserts 30 changing the cavity of the cylinder. Of the Dosing cylinder 18 is guided in seals 31 of housing 17.

With the aid of the metering cylinder 18, the same amount of dressing agent is always extracted from the removal container 10 the metered amount of seed. The connector 28 ensures that the amount of liquid contained in the metering cylinder 18 when it is raised of the metering cylinder can only run down when the upper edge 24 of the metering cylinder 18 is raised above the liquid level has been.
