Description

Oberhalb des Stabes ist der Raum frei von Einbauten, so daß überzählige Kartoffeln auch nach Passieren des Stabes frei in den Vorrat zurückfallen können. In den Bereich des oberen Abstreifelementes gelangen nur noch ganz vereinzelt Brücken, die dann dort zum Einsturz gebracht werden. Zur weiteren Ausgestaltung der Erfindung ist vorgesehen, daß auch das im oberen Bereich der Förderbahn angeordnete Abstreifelement als Stab ausgebildet ist.Above the rod, the space is free of built-in components, so that there are no more Potatoes can freely fall back into the supply even after passing the stick. Only a few bridges reach the area of the upper stripping element, which are then brought to collapse there. To further develop the invention it is provided that also in the upper Area of the conveyor track arranged Stripping element is designed as a rod.

Die Erfindung sieht weiterhin vor, daß die Schöpforgane beiderseits dachförmig geneigte Gleitflächen aufweisen. Diese bilden beim Schöpfen den unerwünschten Zweit- und Drittkartoffeln keinen Halt, so daß diese abrutschen und nicht mehr zur Bildung von Kartoffelbrücken beitragen können. Es ist nach der DT-OS 2231 358 zwar bekannt, zur Aufnahme von Kartoffeln dienende Näpfe mit schrägen Gleitflächen zu versehen. Diese bekannten Gleitflächen können aber den Schöpfvorgang nicht beeinflussen, weil sie während des Schöpfens bzw. des Aufsteigens der Schöpforgane keine nach unten geneigten Dachflächen bilden, auf denen die Kartoffeln abrutschen können. The invention also provides that the scoop members on both sides Have roof-shaped inclined sliding surfaces. These form the undesirable when scooping Second and third potatoes do not have a hold, so that they slip off and no longer for Formation of potato bridges can contribute. It is according to DT-OS 2231 358 though known, serving to accommodate potatoes bowls with inclined sliding surfaces Mistake. However, these known sliding surfaces cannot influence the scooping process, because during the scooping or the ascending of the scoop organs they do not follow Form sloping roof surfaces on which the potatoes can slide.

Eine Beispielsausführung der Erfindung ist zeichnerisch dargestellt Fig. 1 zeigt einen Längsschnitt durch die Legemaschine, wobei die Schnittebene durch die Mitte des Schöpfbandes geführt ist, so daß die in Fahrtrichtung linke Reihe der Schöpforgane nicht dargestellt ist, zwecks deutlicherer Sicht auf die Abstreifstäbe. An exemplary embodiment of the invention is shown in the drawing Fig. 1 shows a longitudinal section through the laying machine, the cutting plane through the middle of the conveyor belt is guided so that the row on the left in the direction of travel the scoop is not shown, for the purpose of a clearer view of the scraper bars.

F i g. 2 zeigt ein Schöpforgan in perspektivischer Darstellung und F i g. 3 das gleiche Schöpforgan aus der Sicht der dem Schöpfband anliegenden Rückseite des Schöpforgans. F i g. 2 shows a scoop in a perspective illustration and F i g. 3 the same scoop organ from the point of view of the rear side lying against the scoop belt of the scoop organ.

Der Kartoffelvorratsbehälter 1 hat die Vorderwand 2, unter welcher die Kartoffeln durch die Öffnung 3 in den Füllraum 4 fließen. Durch diesen wandert das aufsteigende Trum des endlosen Schöpfbandes 5, das mit zwei in geringem Abstand nebeneinander angeord- neten Reihen von Schöpforganen 6 besetzt ist. Diese nehmen im Füllraum 4 Kartoffeln auf und fördern sie über die obere Umlenkrolle 7 in die Legeschächte 8. The potato storage container 1 has the front wall 2, under which the potatoes flow through the opening 3 into the filling space 4. Wandering through this the ascending strand of the endless scoop belt 5, the one with two at a short distance arranged side by side Neten rows of scoop organs 6 is occupied. Take this 4 potatoes in the filling chamber and convey them over the upper pulley 7 into the Laying shafts 8.

Im Füllraum 4 ist der Abstreifstab 9 so angeordnet, daß er mit dem aufsteigenden Trum des Förderbandes einen nach oben offenen spitzen Winkel bildet. Der Abstreifstab 9 hat eine in geringem Abstand vom Schöpfband parallel zu diesem verlaufende Verlängerung 10, deren unteres Ende in eine am Vorratsbehälter befestigte Führungshülse 11 eingreift. Nach oben hin ist der Stab 9 bogenförmig verlängert und an der Behältervorderwand 2 befestigt. In the filling chamber 4, the stripping rod 9 is arranged so that it can with the ascending strand of the conveyor belt forms an upwardly open acute angle. The stripping rod 9 has a small distance from the scoop belt parallel to this extending extension 10, the lower end of which is attached to a storage container Guide sleeve 11 engages. The rod 9 is extended in an arc shape towards the top and attached to the container front wall 2.

Das Schöpforgan 6 hat eine becherförmige zur Aufnahme der Kartoffel dienende Höhlung 13 mit einem oberen scharfen Rand 14, an den sich eine schräg nach außen führende Randfläche 15 anschließt. Auf der dem Schöpfband anliegenden Rückseite des Schöpforgans sitzt eine nach aufwärts gerichtete mittige Nase 16, mit einer oberen etwa waagerecht verlaufenden Firstkante 17, von der aus beiderseits dachartige Gleitflächen 18 schräg nach abwärts führen. Am Schöpforgan befindet sich eine vertikale Lasche 19 mit den Befestigungslöchern 20, die zum Anschrauben des Schöpforgans an das Schöpfband dienen. The scoop 6 has a cup-shaped shape for receiving the potato Serving cavity 13 with an upper sharp edge 14, to which a diagonally after outside leading edge surface 15 connects. On the reverse side that lies against the ladle the Schöpforgans sits an upwardly directed central nose 16, with a upper approximately horizontally extending ridge edge 17, from which both sides roof-like Guide sliding surfaces 18 obliquely downwards. There is a vertical one on the scoop Tab 19 with the fastening holes 20, which are used for screwing the scoop on serve the ladle.

Im oberen Teil der Förderbahn ist der Abstreifstab 21 angeordnet, der mit seinem unteren Ende in spitzem nach oben offenem Winkel zur Förderbahn in den Raum zwischen der Schöpforgane mittig eingreift Nach oben hin ist der Stab 21 bogenförmig verlängert und mit seinem oberen Vorderende 22 an den Legeschächten 8 befestigt The scraper bar 21 is arranged in the upper part of the conveyor track, with its lower end at an acute upwardly open angle to the conveyor track in the space between the scooping elements engages in the middle. At the top is the rod 21 Extended arcuately and with its upper front end 22 on the laying shafts 8 attached

Claims

Claims: 1. Potato planting machine with in the vertical plane circumferential pumping station with two on a conveyor belt next to each other at a small distance arranged rows of scoops, which potatoes from a storage container scoop, on a substantially vertical conveyor track to a deflection point and continue through laying shafts to a dropping point where the potatoes both rows are placed in the same furrow, and with one on the machine immovably attached and between the rows at an acute angle to the ascending conveyor track running device to avoid potato bridges with a stripping element in the upper region of the conveyor track, characterized in that the device still has a second stripping element, which is of one in the lower region of the ascending Conveyor track arranged rod (9) is formed.

2. Potato planting machine according to claim 1, characterized in that that the stripping element (21) arranged in the upper region of the conveyor track also is designed as a rod.

3. Potato planting machine according to claims 1 and 2, characterized in that that the scoop members (6) have roof-shaped inclined sliding surfaces (18) on both sides.

The invention relates to a potato planter with in vertical Level circumferential pumping station with two next to each other on a conveyor belt at a short distance arranged rows of scoops, which potatoes from a storage container scoop, on a substantially vertical conveyor track to a deflection point and continue through laying shafts to a dropping point where the potatoes both rows are placed in the same furrow, and with one on the machine immovably attached and between the rows at an acute angle to the ascending conveyor track running device to avoid potato bridges with a stripping element in the upper area of the conveyor track.

According to DT-Gbm 19 88 804, such laying machines are known. the The stripping device is designed as a central rib.

Potato bridges - preferably form smaller ones when scooping up Potatoes. In the known stripping device, the supernatant occurs that a Part of the bridge potatoes from the midrib is not thrown off, but that rather, the potatoes are supported on the flanks of the midrib and by the Scoop can be transported further.

These little potatoes have in the corner space between the ladle the scoop and the midrib a fairly safe position from which they cannot can fall off more because the midrib blocks their way. These potatoes then migrate through the laying shafts and are in the ground furrow as clusters filed, with all the disadvantages resulting from this in terms of plant cultivation. With these known machines it is therefore necessary for planting smaller potatoes, except for the To arrange a vibrating mechanism in the middle rib, which is caused by vibrations of the laying belt Shake excess potatoes out of the cups for easy topping is guaranteed.

Such additional shaking devices are required on a case-by-case basis Careful adjustment for the potato variety in question, so that the vibrating effect is dosed in such a way that not all potatoes are shaken out of the scoops will.

According to DT-PS 2 73 171, a bucket planting machine is tongue-shaped known curved Abstreifstäben, which are acute-angled to the ascending conveyor track the scoop organs are arranged. However, these scraper bars do not have the task of to eliminate bridging between two rows of scoop organs.

The tape is here namely only with a single row of scoop organs occupied, so that the bridging in question cannot occur at all. the Scoop organs are designed as three-pronged forks, which from the outset several Pick up potatoes, and the scraper bars' are arranged so that they are between the forks grip and the scoops grab the excess potatoes push away.

It is also known according to the DT-OS 19 15 927 a laying machine, which uses a circumferential squeegee belt to avoid potato bridges, which in the upper part of the ascending conveyor track runs at an acute angle to it. The belt also exerts an upward acceleration on some of the potatoes from, under whose action individual potatoes over the immediately following Deflection point can be torn and as undesirable multiple layers in the ground furrow reach.

This device can therefore only perform its task very imperfectly. In addition, the wiper belt on this machine requires the arrangement of two separate pumping stations, each with its own pumping mechanism.

The DT-PS 1 99853 shows a spreading machine with diagonally rising Laying belts, which are occupied with cells for scooping the potatoes. Between ever two rows of cells is one to the ascending one to avoid potato bridges Conveyor tracks arranged at an acute-angled web. The one that rises at an acute angle The course of this web begins to be effective in the lower area of the conveyor tracks However, the bridge is only in the upper area, since it is only there that it has sufficient height has reached.

The present invention is based on the object to improve the laying machine described so that with simple means the danger of multiple occupations, as it exists in particular with small potatoes, avoided and all surplus potatoes are returned to the potato supply.

To solve the problem, it is proposed that the device still has a second stripping element, which is of one in the lower region of the ascending Conveyor track arranged rod is formed. The arrangement of the rod in the lower Part of the conveyor line eliminates most of the potato bridges and with from the start proportionately to them the small potatoes.
