Description

The invention relates to potato planting machines according to patent 388043, at to which a spring, which can act on the parts carrying the plant hole stars, is mounted between two mutually displaceable disks, which opposite one with two stops provided and connected to the carrier of a star planting hole are displaceable in such a way that they are frictionally engaged with the adjacent stop Able to connect, and who in turn each carry a stop, and with them Furthermore, an actuator is provided which, when adjusted in the one sense with the Strikes one disc and, in the case of an adjustment in the other sense, with the Abutment of the other disc is able to come into force-locking connection.

The subject of the invention is a particularly simple machine of the type mentioned.

An exemplary embodiment of the subject matter of the invention is illustrated in the drawing, namely shows

Heinrich Klaus in Essen, Ruhr,

Potato planting machine, parts that are not essential to the invention are omitted,

Fig. 2 shows a section of a single device in connection with the adjacent parts the machine,

Fig. 3 the left view of Fig. 2 and Fig. 4 the section according to 4-4 of Fig. 2 seen from above.

About an axis C which is mounted in the not shown frame of the machine, is consisting of two side bars D and a round crossbar D ¹ DD lifting frame ¹ pivotally (fig. 1). With the transverse 'D rod of the lifting frame ¹ DD ¹ is a lockable hand lever in different positions E \ is connected, can be lifted by the lifting frame ¹ and DD lowered. The axis C also carries bow- shaped supports G lying above the transverse star D, on which a shaft F ^1, which is used to accommodate planting hole stars F , is mounted. Between the cross rod D ¹ and each carrier G, a spring H j is connected with tension so that a movement of the Qutrstange D ¹ upwards or | is transferred to the carrier G below while increasing the tension of the spring H. While with the corresponding execution; Examples of the main patent to \ acting on the spring other than a region surrounded by the> spring bar nor a special actuating member is required to Fig. 9, this does away with the present embodiments. With him, one of the j number of carriers G corresponding number j guide pieces ^ ² (Fig. 2) is connected to the cross rod D ^{1, each}

with two | (-shaped guide strips d ³ in

a box-shaped cross pieces g ¹ connected to the carrier G are guided. One j each near the crossbar D ¹ in the guide | bar d ³ mounted bolt d ^l protrudes through the j head k ¹ each of a rod K lying between the guide bar η <2 ³ and passing through a cover plate g ^{4 of} the crosspiece g ¹ , which is surrounded by the spring H. The fairy- ! the H lies between two with contact flanges | m ¹ and n ¹ provided, sleeves M and N which can be moved on the rod if. In general, under the action of the spring // the sleeve M is supported with its end face m ^s on a shoulder surface k ² (Fig. 3) of the rod head Ä ¹ as well as with its flange m ^{l on a web 2 of} the Ouerstückes g ¹ encompassing the sleeve M and the sleeve N with its end face n ² against one on the end of the rod K ; screwed nut P as well as with its flange n ¹ against the cover plate g ^{4 of} the cross piece g ¹ . !

If, when using the potato planting machine explained, it turns out that the distance to the planting hole is too large or too small, the penetration depth of the planting hole stars F must be increased or decreased. For this purpose, the hand lever E and the associated crossbar D ^{1 are} lowered or raised. If the cross rod D ^{1 is} lowered from the position shown in the drawing, each guide piece d ^z and the rod K connected to it by the bolt d * move with the sleeve N downwards. The springs H are compressed further, so their tension is increased. This increased tension is transmitted via the flanges m ¹ and the webs g ² to the cross pieces g ¹ and thus also to the girders G, which are consequently lowered. This results in an increase in the depth of penetration of the plant hole stars. If the cross rod D ^{1 is} lifted out of the position shown in the drawing, each sleeve M also moves upwards as a result of the abutment of its end face m ² against the shoulder surface k ^{z of} the rod head k ^1. The springs H are compressed further in this case too, so their tension is increased. The increased tension is transmitted through the mediation of the flanges n ¹ and the cross pieces g ¹ to the girders G, which are therefore lifted. This results in a reduction in the depth of penetration of the star F planting holes.

Claims (1)

Patent claim: Potato planting machine according to patent 388043, in which a spring, which is able to act on the parts carrying the star-shaped planting holes, is mounted between two mutually displaceable disks, which are displaceable in relation to a body provided with two stops and connected to the carrier of a star-shaped planting hole, so that they can be moved with the adjacent stop are able to come into force-locking connection, and each in turn carry a stop, and in which an actuator is also provided, which in an adjustment in one sense with the stop of one disc and in an adjustment in the other sense with able to enter into force-locking connection with the stop of the other disk, characterized in that the actuator formed by a rod (K) surrounded by the spring (H) is connected to the transverse rod (D ¹ ) . 1 sheet of drawings.
