RodescharLifting share

Der Erfindung liegt die Aufgabe zugrunde, einen Kartoffelroder zu schaffen, der folgenden Forderungen gerecht wird: i. weitgehende Einschränkung der bei der Ernte mittels Maschine immer noch notwendigen Handarbeit, die zum Aufsammeln der gerodeten Kartoffeln angewandt werden muß; 2. möglichst geringe Beschädigung der Kartoffeln beim Roden; 3. Einfachheit in der Bedienung und in der Herstellung sowie hierdurch erzielte Verbilligung, einfache Wartung und lange Lebensdauer.The invention is based on the object of creating a potato harvester that meets the following requirements is fair: i. far-reaching limitation of what is still necessary when harvesting by machine Manual labor that must be used to collect the cleared potatoes; 2. As little damage as possible to the potatoes when clearing; 3. Ease of use and manufacture as well as the resulting reduction in price, easy maintenance and long service life.

Bei zur Zeit üblichen Maschinen, die nach dem Schleudersystem arbeiten, werden die Kartoffeln leicht durch den Zugriff der Gabeln des Schleuderrades und bei Anwendung einer Fangvorrichtung durch ihren harten Anprall an diese verletzt. Bei Nichtanwendung einer Fangvorrichtung liegen die gerodeten Kartoffeln in einem mehrere Meter breiten Streifen verstreut, wodurch die Arbeit des Aufnehmens erschwert und der Verbrauch an Arbeitskräften erhöht wird.With machines currently in use, which work according to the centrifugal system, the potatoes easy by accessing the forks of the centrifugal wheel and using a safety gear injured by their hard impact on them. If a safety gear is not used, the cleared potatoes are scattered in a strip several meters wide, thereby making the work of picking up difficult and the consumption of labor is increased.

Diese Nachteile werden bei Anwendung einer beweglichen Rodeschar nach der Erfindung ausgeschaltet. Die Schar steht schräg zur Arbeitsrichtung und ist um eine durch ihre Spitze gehend gedachte Achse schwenkbar, die vorzugsweise as senkrecht zur Arbeitsebene stehen soll. Sie läuft in einen sich nach hinten erstreckenden Rost aus, der zur Arbeitsebene etwas geneigt ist. Rost und Schar schließen einen stumpfen Winkel zwischen sich ein. Schar und Rost werden in eine hin und her gehende Schwenkbewegung um die durch die Sdharspitze verlaufende Achse versetzt.These disadvantages are eliminated when using a movable lifting share according to the invention. The flock is inclined to the working direction and is intended to go through its tip Axis pivotable, which should preferably be as perpendicular to the working plane. She runs in a rearwardly extending grate that is slightly inclined to the working plane. Rust and share enclose an obtuse angle between them. The share and the grate become a reciprocating one Pivoting movement offset around the axis running through the Sdharspitze.

Die gerodeten Kartoffeln liegen nach dem Durchgang durch die Maschine in seitlich streng begrenztem Band, etwa furchenbreit auf der Kartoffelfurche, nachdem sie durch das Schütteln auf dem an der Schar fest angebrachten Rost mechanisch von loser Erde, Erdklumpen und Steinen getrennt worden sind.After passing through the machine, the cleared potatoes lie in a strictly limited area Tape about the width of a furrow on the potato furrow after shaking it on the The grate firmly attached to the coulter is mechanically separated from loose earth, clods and stones have been.

are explained below using an exemplary embodiment (Fig. ι to 6).

Fig. Ι to 3 represent the lifting share in side view, plan and front view; · Fig. 4 to 6 show the! built Schar in side view, plan and diagonal; opinion.

The movable lifting coulter is installed in a frame K which forms the supporting frame and which can be changed in its distance to the earth's surface by means of a lever transmission that is already common on other agricultural machines. It consists of a triangular, trough-shaped coulter A, which is directed forwards and downwards in the working position and which is firmly but interchangeably connected to a bar grating B at its rear end. This bar grating is at an obtuse angle to the coulter and is directed backwards with a slight incline in the working position. When working, the share point C runs in a level that is about 22 cm lower than that of the grate B , so that on the one hand the share A can reach under the deep-seated potatoes and on the other hand the bar grate B can move freely above the surface of the earth.

The bar grating consists of bars, the spaces between which are dimensioned so that usable potatoes do not fall through, but the loose earth sags easily. On the bar grate mounted lateral guide cheeks D force to go through the entire, detected by the coulter Rodegut (soil and potatoes) the way through the grate.

The share with grate is held and moved by a laterally arranged, curved, simple holding arm F attached to the share. This will continue to be called carrier F. In its upper part it ends in a shaft extension E , which is fixedly but rotatably mounted in a frame A 'provided with wheels /. It is important that the group A and the carrier F are positioned relative to one another in such a way that the tip C of the group lies exactly in the extension of the axis H of the shaft extension E of the carrier F. An arm G with a joint ball is attached to the side of the carrier F , which transfers the shaking movement, which is derived from one of the running wheels by means of a countershaft, eccentric disc and transmission rod (crank drive L) when the machine is moving forward, to the carrier and thus to the coulter and grate.

As a shaking movement, the coulter and the grate perform a laterally sharply delimited, back and forth swiveling movement. The axis around which this takes place is the axis of the shaft extension E of the carrier F, which meets the coulter tip C in its extension, so that this does not get a lateral deflection, but always works its way through the soil in a straight line, the coulter on the whole, the breaking of the seized soil is facilitated by slight vibrations. This is intended to ensure that the flocks work smoothly and without interference. The grate, on the other hand, shows larger deflections during the shaking movement (vibration).

After the coulter with the grate has been lowered into the working position by lowering the frame has been so that she can reach under the potato plants, and after the vibrating gear is switched on has been, the coulter is through the forward gear of the machine under the to be cleared Pulled along the row of potatoes. The coulter and grate are in the shaking motion described above. The harvested material caught by the share inevitably slides on the trough-shaped share up on the grate. Here potatoes and earth are separated by the shaking movement, as the heavy earth pushes down and finally falls through the grate, while the potatoes are only fall to the ground behind the grate. Here they lie closed together in a band roughly the width of a furrow and can be easily picked up. If, however, not all of the earth is through during this process the grate falls and earth, clods of earth and stones leave the grate together with the potatoes, the potatoes would always be on top because they are lighter than the other grub.

The invention is intended to enable potato lifting that is gentler and more economical than before: In addition, it should simplify and reduce the cost of lifting machines in terms of manufacture, acquisition, Cause operation and maintenance.
