PATENTAM

The present one differs from the usual potato planting machines in that the The distance between the furrows can be changed quickly. Furthermore, the evil becomes avoid throwing the seed potato; it is rather applied to the Ground, laid. The new machine will provide the necessary for the good utilization of the soil the same distance between the potatoes is achieved, because the machine runs with the help of four change gears the laying of the potatoes in four different even distances into the ground and the potatoes continue to roll, as is inevitable when throwing is the case, does not occur because the potatoes do not make a free fall movement, which is why the potatoes cannot be wasted or wasted either.

Each rear wheel A of the machine has a shaft a, at both ends of which levers bb sit loosely on pins (see FIGS. 1, 2, 3, 4 and 5). These have lugs b ^l b \ with which they rest in the bearings cc, which are attached to the angle iron BB, Fig. 5, at the free end. On the lever b, FIGS. 4 and 5, there is a lever rod P with a locking device & ⁴ , which is pressed into the quadrant b ¹ by the spring b ⁵ locking at the free end with the projection b ^e. For safe guidance of the lever arm b ² is an over the quadrant b ¹ hook-shaped bent and screwed on b ² angle b ^a, Fig. 5. The lever b has an approach b ^9, Fig. 4, on which the angle irons B when the machine is in operation, as shown in FIG. 4, at rest. If the machine is to be transported, the lever rod b ² , Fig. 3, is first turned through 90 °. This then also brings b into a vertical position and thereby raises angle iron BB by the distance from ¹ upwards, so that the machine shows the position of the relevant parts shown in FIGS. 2 and 3. On the shaft a sits on the right side (Fig. 1, 3, 4, 5 and 9) a gear d, in which gear d ^l engages; this meshes with a gear d ' ² ,

Fig. 9, which is stuck ^{on the shaft d a.} d ^l sits on a bolt d ^B , which by nut d *, Fig. 5, is held in a longitudinal slot of the lever d ⁵ . Lever d ^b carries a locking device which engages in quadrant d ¹ , FIGS. 5 and g, in order to hold d ⁵ with the transmission wheel d ¹ in any position.

If the machine is in operation, then d ¹ must be allowed to intervene in d and d ?, FIG. 9, then d moves with α through A and transfers the movement further. If the machine is operating, besides, one has to provide high-d ⁵ (Fig. 3), then A can rotate without meshing DAF d in d ^l.

With dp at the same time the person sitting on the shaft ⁸ pulley d E, Figure 1 rotates., 5,6 and 13. By means of screw e ¹ is the same screwed through the collar-like approach, e ^2, Fig. 8, on d ^8. The spoons that place the potatoes in the ground sit on the disk E. They consist of a fixed part e ⁴ and a movable part e ⁵ . At the outer end they have semicircular hollows that hold the potatoes. The rivets e ⁶ , which on the one hand sit in the washer E , on the other hand connect a ring e ⁷ with e ⁴ . The rotatable spoon-like parts e ⁵ move into the gap created by e ⁴ between e ⁷ and E. The same sit rotatably on a pin e ⁸ , which rests in E and e ⁷ and on the outside of E a spring F, FIGS. 7 and 8, carries. A washer and nut are provided so that the spring, which sits firmly on the pin, does not slip off. A pin f ¹ holds F in tension, whereby e ^{s is} pressed against e ^i.

The opening of the spoon, which is necessary for picking up a potato, is effected by the lever G, FIGS. 1, 4, 6, 8 and 13, with its segment g, FIGS. 6 and 13 adapted to ^{the inner edge of the ring e 7.}

The lever G sits loosely on the shaft d ^s and is fixed to the angle iron H at the free end. The spoon-like holders e ⁵ have inwardly arcuate extensions e ⁹ , FIGS. 6 and 13, which protrude ^{beyond the inner edge of the ring e 7.} The segment g ¹ covers the gap ■ during the distance on which the spoons must be open. Because g ¹ remains at a standstill, the disk E, Figs. 4, 6 and 13, but rotates in the direction of the arrow, the protruding part of e ⁹ hits the segment, the spring F yields, e ⁹ is turned over and at the same time e ⁴ e ⁵ open. When the spoon in question has passed the segment, the spring F pushes the spoon e ⁵ back onto e ⁴ . The time during which e ⁴ e ^{5 must be} open is shown below.

The potatoes are thrown into box J, Figs. 1, 3, 4, 5 and 13, which has as many compartments as there are rows to be tilled at the same time, in the present three as can be seen.

Downward J is tapered and has small cross boards i \ Fig. 1, which, for the lower opening ^'2, Fig. 1 and 13, constrict also in this direction. So that no more potatoes can fall through, the opening is partly closed with a flap z ³ . z ^{3 is attached to shaft z '5} by means of screw i *, which goes through the whole box and is ^{guided on both sides in bearings attached to frame JB 1} , Fig. i. On the left side of the machine z ⁵ carries a two-armed lever z ' ⁷ , Figs. 1 and 2, one end of which rests on the spring z' ⁸ attached to B ^{1 in} such a way that z ' ⁸ holds the lever f horizontally, -and also the flaps i ³ : on α, Fig. i, there is a lifting thumb z ' ⁹ , which grips under the free end of e ¹ once with each rotation of α and lifts it up; this opens the flaps i ³ downwards. If z ' ^{7 is released} from z' ⁹ , the spring i ⁸ lifts the opposite end of z ' ^{7 up} again and the flaps close the opening again.

The relation of z ^'9 to z' ⁷ is such, that not fall too much or too little potatoes. Have the potatoes, the flap z ^'3 passirt, they fall into the hopper L, 10 and ι. 3; at the top it has more than twice the width of the lower opening of J. With the rear edge it cuts off with J and protrudes to the front; it is held at the rear by riveted flat irons / 'which rest on angle irons K, FIG. 4. A flat iron / ² , Fig. 10, 11 and 13, with pins / ³ lies across the funnel. The pins I ³ come behind the flat iron / ⁴ , which rests on-JB ¹ JB ¹ , Fig. 5, and cuts off with the front lower edge of the box J. Two screws for each funnel attach the same to / Λ

L is closed at the bottom, as shown in FIGS. 10, 11, 12, 12a and 13, by six brackets Z ⁵ . These can be opened from below, leaving only such a small opening at the top that no potatoes can fall through. The brackets can be rotated around a wire / ⁶ lying around the outside and are bent at an angle at the top, which lies against the funnel. The springs / ⁹ on the inside press the brackets towards the middle and thus form a lock through which the potatoes cannot fall. So that the potatoes cannot roll out at the top, the funnel has an extension piece L ¹ , Fig. 3, 5 and 13, which is screwed firmly to the box J in the middle track and adjustable to the box for the others. The front surface of the funnel L palms the shape of the spoon plate E because the fixed spoon e ⁴ den

Funnel has to go through from bottom to top (Fig. 13).

For this purpose, L and L ^{1 are} cut open on the front wall (Fig. 11); the funnel has two springs MM lying on top of one another inside, which are fastened to the front wall by rivets.

The working process of the spoons is as follows (Fig. 13):

If e * comes down into the vertical position, g ^x opens the spoons e ⁴ e ⁵ by turning over e ⁹ . Before the spoon e ⁴ enters the slot of the funnel L , spoon e ^{5 is placed} in the semicircular cutouts in the disks E and e ^7. The spoon e ^{4 pushes the bracket / 5} outwards when it enters,!, Which immediately close again after the spoon has passed through.

On the way through the funnel, the spoon e ⁴ picks up a potato in its cavity. In order to avoid,. that a potato could sit in front of the spoon, which would be crushed or could close the slit, the intersecting springs M (Fig. n) serve.

Before e ⁴ , FIG. 4, the attachment L ^{1 of} the funnel L leaves, e ^{5 is released} by the segment g ¹ and, tensioned by the spring F , folds onto the potato resting in the spoon e ^4; it cannot leave the spoon before the parts e ⁴ e ⁵ open and lay them on the ground. This happens, as described, when the spoon e ^{4 has} come into the vertical position below.

The gear ratio is chosen so that the spoons always take away the potato that lets the flap i ³ fall through. In other words, the flap regulates the filling so that no emptying, but also no excessive accumulation, can take place.

If the track width is to be changed, the screw e ^{1 of} the disk E, FIG. 5, is loosened, the desired distance from the central disk is established and the screw is tightened again. At the same time the screws / ⁷ , Fig. 5, of the funnel L are loosened and also those of the attachment Z ⁸ , both of which have to slide in slots. The funnel and attachment are then adjusted according to the washer E and the screws are tightened again.

Plowshares go in front of and behind each spoon disc, which are operated by levers and rods and chains are connected and can thus be placed high and low.

By means of lever N , as shown in FIGS. 1, 2 and 3, they can be kept high during operation and lowered for operation by simply turning the lever, as shown in FIG Level the ground at the back and cover the potatoes.

To a secure opening of the spoon to allow independent of the magnitude of the potatoes and press lightly as possible to the potato to the loose spoon, the impact spring F is according to the construction of FIG. 14 and 15 instead set a lever transmission, which of the the trough movable spoon slightly against the. firm spoon presses. Is the potato gröfser, as is the cavity, then gives the spring to 0 and the seated at the hollow pin υ 'which has ⁵ guide the dipper e, gives leeway. On the square extension of the pin e ⁸ sits a lever arm p ¹ , which is articulated to one end of a two-armed lever p ² by p ^3. p ' ¹ swings around the pin p ⁱ seated in E and is guided at the free end through the arch q seated on d ⁸ , which is connected to an angle iron on the machine by means of q ^{1. l}
