摘要:
Device at a following harrow for agricultural implements. A following harrow entity (26) comprising two soil-cultivating tines (22) connected with each other via a cross- part (30) that extends essentially across the driving direction of the agricultural implement. The cross-part (30) is moveably arranged at an intermediate part (50) in turn arranged at a carrying arm (22) so that it is allowed a rotational movement relative to the carrying arm (22) about the cross-part (30). The intermediate part (50) comprises movement-limiting members (56) that limit the backward rotational movement of the following harrow entity (26). The rotational movement is enabled via an adjustment apparatus (70).

Die Erfindung betrifft eine einklappbare Bestellkombination mit Saatgutbehälter und Reifenpackerwalze als Fahrwerk, bei der der Saatgutbehälter verschwenkbar oder verschiebbar ausgebildet ist, um zum einen ein Einklappen der Reifenpackerwalze zu ermöglichen und zum anderen eine Veränderung der Gewichtsbelastung auf die Reifenpackerwalze bewerkstelligen zu können.
摘要:
An agricultural soil cultivation device comprising at least ground roller provided with tyre elements rolling on the ground. Some of the tyre elements can be used as a travelling device for transporting the soil cultivation device on roads and can be placed in a downward protruding position in relation to the other tyre elements. In order to use individual roller elements, which are arranged in the levelling system of soil cultivation devices which are provided with rollers and which have levelling systems, for additional transport purposes, the roller consists of several tyre elements which are arranged next to each other and which are respectively disposed on individual pivoting arms, whereby the height thereof can be adjusted in relation to each other, on a supporting beam which extends in crosswise manner. At least one pressure compensation system is associated with the individual pivoting arms. The pressure compensation system is embodied in such a way that the tyre elements forming the travelling device for transport are impinged upon with higher pressure than the other tyre elements in the levelling system.

A direct sowing machine comprising coulter structures (3) including coulter disks (4) for cutting and opening furrows in soil for conducting seed into there is characterised in that it comprises a rake (8, 9) in front of the coulter structures (3) for leveling and removing off straw residue and other such matter from the way of the coulter disks. The rake is advantageously consisting of tines (8, 9) placed in one or more rows such that for each coulter disk (4) there is a corresponding tine (9) placed in alignment with the coulter disk. The tines of the rake clean the way of the coulter disks and level heaps of straw on the surface of a field whereby the coulter disks are pressed evenly into the soil and the result of the seeding is good and of uniform quality.

According to the invention, the soil is broken up with soil-working elements to form furrows in preparation for sowing and placing the seeds. A seedbed (11) is prepared using the rake elements (5) corresponding with the elements for placing the seeds (12). Seeds are then deposited on said seedbed via the rake teeth and the seed-placing elements (12), said rake teeth (9) pushing the large organic material aside in order to keep the seed furrows free. A clearing device, preferably in the form of a punching roller (15) with punching elements (16, 16', 16'') then removes the material collected between the rake teeth and keeps it away from the seed-placing elements (12). The rake teeth (9) or levelling elements prevent obstructions of organic material. The clearing or punching elements (15) which are configured so that they are flexible in a peripheral direction work in conjunction with a fixed stop in order to prevent any damage being caused by striking an obstacle (4). A fixed levelling element (17, 17') is positioned between each pair of rotating punching elements (16, 16'), said levelling element exerting a pressure on the soil and pressing on the seeds. This halves the number of punching elements required.

Säschiene (7) mit mehreren daran jeweils über einen Träger (9a, 9b) angelenkten Säscharen (11a, 11b) mit jeweils nachgeordneter Druckrolle (12a, 12b), wobei die Säscharen in Arbeitsrichtung gestaffelt in zwei Reihen angeordnet und die Säscharen (11a) der vorderen Reihe mit ihren Trägern (9a) an einer vorderen Querachse (10a) der Säschiene (7) und die Säscharen (11b) der hinteren Reihe über ihre Träger (9b) an einer hinteren Querachse (10b) angelenkt sind, der Querachsenabstand etwa dem Staffelversatz der beiden Säscharreihen entspricht, und die Träger (9a, 9b) beider Säscharreihen über Anschlagarme mit verschiedenem Winkelverlauf mit einem gemeinsamen Tiefenbegrenzungsanschlag (16) zusammenwirken.
摘要:
A harrow comprises a frame (2) which supports cutting means (6, 8) and a lift mechanism (48). An engine (10) is mounted on the frame (2) and is adapted to be connected to and to operate an auxiliary device (16). A linkage arrangement (22) is provided at the rear of the frame (2), the linkage arrangement (22) being adapted to be connected to the auxiliary device (16). The lift mechanism (48) is operable to move the linkage arrangement (22) between a raised position and a lowered position.

Ce semoir comprend un châssis (1 ; 2) supportant une trémie à semences (200) et destiné à être attelé à un tracteur, une rangée transversale de bras porteurs (3) disposés longitudinalement sous le châssis (1 ; 2) portant chacun une paire d'outils semeurs décalés en direction longitudinale qui sont alimentés en semences à partir de la trémie (200) et une rangée transversale de rouleaux suiveurs (4) montés individuellement fous en rotation sur les bras porteurs (3), chacun des bras porteurs (3) étant articulé à l'avant, indépendamment l'un de l'autre, par leur partie avant autour de tronçons d'arbres alignés (70) horizontaux et transversaux sur une biellette (33) elle-même articulée au châssis (1 ; 2), une série de ressorts avant (6A), et arrière (6B), disposés respectivement en avant et en arrière des outils semeurs (5, 5') sollicitant en permanence chacun des bras (3) au pivotement du haut vers le bas. Il est remarquable par le fait que chacun desdits bras porteurs (3) est équipé d'au moins un organe d'appui au sol (6) situé en avant de la ligne (70) desdits tronçons d'arbres, cet organe d'appui étant réglable en hauteur.
