Definitions

  • the invention relates to a tillage machine with a sowing device and with a trailing soil compaction roller.
  • the soil is prepared in a conventional manner by plowing and depositing the seed, or, if the soil is only surface-treated, by tearing the soil and then sowing or with the aid of seed coulters.
  • the seed is placed in the soil with as little intervention as possible, and a seed bed is still created for the material to be put down.
  • the object of the invention is to propose a tillage machine which has tools with which recesses or hollows are formed for receiving seed or fertilizer, which are arranged in the direction of travel at a distance from one another as individual hollows, or directly one behind the other in the form of a type of gutter, the material is fed through an internal filling on the tools, and a subsequent soil compaction is carried out.
  • the soil compaction roller has its own drive and its peripheral speed is adjustable.
  • the surface of the soil compaction roller can be smooth or textured. Because the soil compacting roller is driven at a higher rotational speed than the driving speed, it becomes a chopping one or smoothing effect on the floor. If the circumferential speed of the soil compaction roller is chosen to be less than the driving speed, a dragging or pushing effect on the soil surface is achieved.
  • the tillage machine is a rotating, cylindrical tool carrier which runs relative to the soil compaction roller and which, e.g. can be driven via an articulated shaft, a chain or the like in order to achieve a differential speed, and which has tools running radially outward on the circumference of the roller, which are connected to the circumference of the tool carrier, for example via tool holders or tool handles.
  • the tool elements which can be exchangeably fastened to the tool handles or holders, are, for example, finger-shaped or rod-shaped elements which penetrate into the ground and dig out or cut out hollows. The shape of such cavities depends on the speed at which the tool carrier with the tool elements rotates relative to the driving speed.
  • cylindrical for the tool carrier encompasses both a continuous and a discontinuous cylinder or drum shape, the latter including star-shaped, disk-shaped or similar individual elements which are arranged parallel to one another and are spaced apart from one another and whose common outer circumference is cylindrical
  • Embodiment of the invention is proposed to design the tools as hollow disc coulters.
  • a large number of such tool handles with tool elements are arranged in parallel next to one another and offset behind one another on the jacket of the tool carrier.
  • the soil cultivation machine is designed as a combined sowing or fertilizing machine, seed, fertilizer or the like is applied in granular form, as granules or the like from a storage container;
  • This material to be dispensed is brought up via hose or piping or the like to the tool stems or holders rotating together with the tool carrier, at the feed parts of the material to be dispensed or at the transfer point of the material, small passageways or transport spaces are created which pick up the transferred goods and place them in the respective cavity due to the rotation of the tool body.
  • the trailing soil compaction roller then presses the soil excavated or excavated by the formation of cavities and thereby covers the spread material.
  • the passage or transport spaces which are formed on the tool handles at the goods transfer points can have U-shaped, curved, groove-shaped, web-like or similar shapes which are suitable for transferring the goods from the goods supply lines to the rotating tool handles.
  • the tool elements of the tool carrier serve to receive the feed of the seed, fertilizer or the like.
  • the feed lines or feed pipes for the goods are designed and arranged such that they are filled internally with the goods.
  • the material outlet can be arranged coaxially to the axis of the tool carrier, so that the direction of discharge of the material after leaving the outlet end of the feed line is at an angle to the vertical and strikes a plate, disk or the like of the tool carrier, from where the material bounces off and on one of the Tool handles are placed radially outwards and on the floor.
  • the goods are guided in the tool handles directly behind the tool element, the tool elements being interchangeable elements on the tool handle.
  • the tool handles can, for example, be U-shaped, angular or the like, or they can be designed as closed hollow handles, in the interior of which the material is conveyed to the outside.
  • guide surfaces can be provided which guide the goods when they are delivered.
  • the soil compaction roller connected downstream of the soil cultivation machine is preferably designed such that the peripheral speed of the roller is greater than the driving speed of the soil cultivation machine.
  • This peripheral speed is advantageously adjustable.
  • a special embodiment of a soil compacting roller according to the invention is designed such that individual stamp elements of a stamping tool are sickle-like elements or spring arms fastened on one side to the axis of the soil compacting roller, the inner portion of which is attached to the shaft and extends radially outward and the outer portion of which adjoins the inner section, is a partial circle adapted to the circumference, which is designed to be resilient in the radial extent and whose free end is spaced apart from the stamp element adjacent in the circumferential direction.
  • the soil stabilization roller according to the invention consists of at least two offset in the circumferential direction, resiliently resilient on the circumferential surface, approximately sickle-shaped stabilization elements, which are designed for example in the form of angled spring arms.
  • the strengthening elements are optionally connected directly to the rotating axis or to flanges attached to the rotating axis, e.g. screwed so that the elements are interchangeable.
  • Each strengthening element has an approximately crescent-shaped shape with an inner section which forms the support section which is connected directly or indirectly to the axle, and an inner section which extends radially outward and preferably integrally connects the outer section and forms part of the circumferential circle forms the device and represents the active or working surface.
  • the free end of the outer section facing away from the inner section of the strengthening element is arranged at a distance from the associated next element, and due to the self-supporting configuration of the outer section of this element, this outer section can deflect elastically and resiliently inward when it encounters an obstacle or the like, the assignment between two adjacent elements is selected such that the free end of the outer section of the strengthening element is deflected onto the radial, inner section of the subsequent ing element or on a limit provided for this purpose, so that this trailing element acts as a stop for the free end of the outer portion of the preceding element.

Abstract

L'invention concerne une machine pour le travail du sol (2) traînant derrière elle un rouleau de compactage du sol (1). Cette machine est un porte-outil cylindrique et rotatif de surface périphérique continue ou discontinue et doté d'outils (9) orientés radialement vers l'extérieur, qui pénètrent dans la terre et forment des creux par soulèvement ou éjection correspondant à la forme de l'outil. L'outil peut être conçu sous la forme d'un dispositif à disques à double enveloppe et former un sillon en forme de cuvette. La machine pour le travail du sol est associée à un dispositif servant à répandre des semences, des engrais ou équivalent qui amène le produit à répandre jusqu'aux outils (9), par l'intermédiaire desquels le dispositif en question introduit le produit dans les creux. La vitesse d'entraînement du rouleau de compactage du sol (1) est notamment supérieure à la vitesse de déplacement de la machine. Dans le cas où l'outil est conçu sous forme de dispositif à disques à double enveloppe, chaque soc à disque à double enveloppe est pourvu d'un dispositif de séparation qui sépare le produit déversé au niveau d'un soc à disque à double enveloppe de la terre détachée par le soc voisin de manière à éviter toute interférence de cette terre avec les semences déversées.
