Description

The invention relates to an on an agricultural vehicle, e.g. B. on one Equipment carrier, attachable haulm topper with a potato harvester assigned to it.

There are haulm toppers known that in a preparatory manner for the potato harvest in a separate Operation smash the potato tops and on the not yet harvested potato field spread broadly. This essentially serves the purpose of the subsequent potato lifting a trouble-free passage of the earth dam through the sieve organs of the potato harvester ensure, in separate and subsequent operations haulm felling and potato lifting are carried out here. This separate way of working requires a considerable amount of time. Furthermore, it has a disadvantageous effect that with the haulm toppers known so far, relatively long herb stalks on the dam remain, which must be processed with the subsequent potato clearing and make it difficult to pick up the potatoes lying on the ground. In this way of working it also happens that ζ. B. after the onset of haulm rain, the herb stalks to stimulates new growth, so that the leaves growing on the stems during the potato lifting process must be processed with.

There are also haulm toppers that are grown directly on the potato harvester are. However, these well-known haulm toppers are only able to knock away small remains of potato cabbage, which on top of that are thrown haphazardly.

The present invention is based on the object to avoid the disadvantages outlined above and to create a haulm topper that can be used in Cooperation with a potato harvester in a coordinated way of working, namely in Haulm cutting and potato lifting is done in one operation, with the small and the cut off Potato tops can be as high and strong as you want. Furthermore, it should be achieved that The small and cut potato tops are deposited in such a way that they can be removed by the subsequent potato lifting process is completely covered with earth, so that when picking up the stored potatoes no herbaceous remains obstructive in the Ways are. The gathering of what is usually lying around in the harvested field Potato cabbage is unnecessary, as the potato cabbage covered with earth is plowed under immediately On an agricultural vehicle

can be and, because it is very finely chopped, does not pose a risk of clogging when plowing.

The object is achieved according to the invention in that the haulm topper and the potato harvester on the agricultural vehicle, e.g. B. on an equipment rack, are arranged offset to one another and one behind the other, the potato harvester, viewed in the direction of travel, in front and the haulm topper is arranged in the back. It is useful when the haulm topper is off consists of at least two striking elements, one above the dam crest and the other above the Dam flank is arranged. According to a further feature of the invention, the haulm topper is one Associated with their profile of the ridge shape adapted, adjustable and lockable ridge drum. Advantageous it is that the planes of rotation of the striking elements with a perpendicular to the direction of travel Include a plane at an angle. In a further embodiment of the invention it is proposed that the Haulm topper at the rear and the potato harvester on the agricultural vehicle between the axles, z. B. on an equipment rack.

An exemplary embodiment of the subject matter of the invention is shown schematically in the drawing. It shows

This haulm lifter 25 Fig. 3 shows the haulm topper with the haulm lifter and is articulated by means of a lever or a parallel one spindle-like drum in plan - not closer for the sake of clarity sees. 5 are denoted - connected to the fork 24 and FIG. 1 shows a motor-driven Ge can thus adapt to the unevenness of the ground, implement carrier 1, on which one with two sieve wheels is attached. On the left side of the haulm topper 3 is one See potato harvester 2 interaxially attached wall 27 is provided, which is preferably made of rubber is. On the back of the device carrier 1, there is an example and the purpose is against this wall wise on the three-point linkage, the haulm topper is 3 io 27 thrown potato haulm in the described arranged, which by means of a cardan shaft 4 deviates from the way in the trough of the excavated dam Insert the PTO shaft of the implement. With 28 are the connecting arms for the carrier 1 is driven. called lower link of a three-point linkage, the operation of these associated while 29 the connecting arm for the upper link and the equipment attached to the equipment rack is as follows: 15 represents. The striking elements 15, 20 on the right from the device carrier 1 is according to FIG. 1, the covering protective plate 30 is intended to endanger the Not yet harvested driver covered with potato tops through flying stones or clods Potato field on which the potato dam 5 prevents it. is posed. The also still untouched potato As can also be seen from Fig. 2, beat the Dam 6 is in the area of the haulm topper 3 from a ° striking elements 15 of the drum 14 essentially Potato cabbage freed so that the main mass of the potato cabbage is in the area 7 to the side freed from the potato tops, but not yet removed, while the beating elements 20 of the drum harvested potato dam is located. The one at the previous dam on its flank of potato tops Clear dam 8 from which the potatoes have been removed. is picked up by the flock of the potato harvester 2, 25 around the other flank of the dam of Kardie The soil is sifted off and the potatoes come to be released potato wed, the cabbage lifter is 25 to lie approximately in the area 8 a. The hollow of the provided, as already described at the beginning, excavated dam 8 is behind the potato According to Fig. 1 is in the present arrangement roder 2 denoted by 9. FIG. 1 also shows the haulm topper 3 and the associated potato It can be seen that the 30 roders 2 cut off from the dam 6 is the still untouched potato field on the right Potato tops come to lie in this trough 9, located by the equipment carrier 1, so that the filed as it come to rest in the area 10 as an extension of the potatoes on the left. The pre-designated trough is shown. This area 10 is therefore the nete structure and the arrangement of the Krautschlämit topped with short-cut potato cabbage. The gers 3 and the associated potato harvester 2 are 35 also possible in a mirror-inverted version, which were discarded and smashed during the previous passage, gene potato tops 11 is approximately in the range of the particularly advantageous in the cabbage topper 3 according to the Potato harvester 2, where the largest screening takes place- Invention affects the arrangement of the spindle, so that the smashed potato tops from a remnant-shaped drum 23, with their help going to be covered with earth. it is possible to copy the unevenness of the ground as precisely as possible essentially of a frame 12 in which the potatoes can be completely knocked away, from the PTO shaft driven shaft 13 rotating The haulm topper 3 with its arrangement and is movably arranged. Working on this shaft 13 is not based on the example shown is found, non-rotatably connected to it, a drum coupling with an equipment rack 1 or the like. Gemel 14 tied to receive and attach the 45. Namely, it is also possible to use the herb-striking elements 15 serves. The striking elements 15 beaters 3 and the potato harvester 2 can be used independently for example, as a rigid or movable dige, drawn structural unit. The herb sticks or be designed as chains. About the racket 3 can be used to work on the same dam Rocker 16, which are rotatably arranged with the shaft 13 in front of the potato harvester 2, is connected and fixed with the aid of an actuator 17 50 The haulm topper 3 can not only be shown can be, there is a drum 19, placed sieve wheel potato harvester, but also a which is similar to the drum 14 and with the potato harvester of any kind, for example, too Striking elements 15 equivalent striking elements are assigned to a collecting harvester. 20 is equipped.
