Definitions

  • the present invention relates to a soil treatment device in the form of a roller for an agricultural device.
  • rollers are usually used to reconsolidate the soil after previous tillage, which can be done at different times or in combination with other soil tillage implements.
  • the weight of the roller is used to work the soil, and on the other hand, a special effect can be achieved in the soil by profiling the lateral surface of the roller. Such a profiling can be achieved, for example, by constructing the roller from individual discs or rings.
  • a roller for seedbed preparation can be arranged directly in front of the coulters in order to cause pre-compaction of the soil.
  • rollers can also be used to guide the depth of a soil cultivation implement, since they usually sink only slightly into the soil and essentially roll on the surface.
  • Such a bottom roller is known from DE 195 17 184 A1, the bottom roller comprising a support tube and compression rings arranged at a distance therefrom.
  • scrapers are arranged which engage between the compression rings and contact the roller or at least come very close to it. The scrapers are used to remove soil debris that accumulates between the compaction rings during work in the field, whereby the scrapers and the soil adhesions can make it more difficult for the soil roller to roll, which can make it harder to pull the roller.
  • a roller for agricultural soil cultivation comprises at least one supporting body rotatably mounted about an axis of rotation and a plurality of compression rings arranged next to one another at a distance from one another on the supporting body for compacting the soil and intermediate rings arranged between adjacent compression rings.
  • at least two intermediate rings have a different diameter and/or a different width.
  • the support body of the roller can be mounted rotatably about an axis of rotation on a support frame or directly on a base frame, for example a combination of several soil cultivation implements such as a tiller combination for seed application.
  • the compression rings of the roller can be slid onto the supporting body in the axial direction, along the axis of rotation.
  • the compression rings mounted on the support body can be spaced apart from one another on the support body side or can be in contact with one another on the support body side be arranged.
  • the compression rings can be designed in the form of so-called trapezoidal rings for row pre-compaction for seed coulters of a tilling combination for spreading seed.
  • At least one intermediate ring can be arranged between two adjacent compression rings, with intermediate rings being able to have different widths in the axial direction and/or different diameters in the radial direction in relation to the support body and/or its axis of rotation.
  • Smaller diameter spacer rings can allow high and easy passage of soil, but may provide less reconsolidation and leveling of the soil.
  • Intermediate rings with a larger diameter, that is, which reach closer to the soil, can allow a higher reconsolidation and leveling of the soil, but can have a smaller and heavier passage of soil due to their radially outer smaller distance to the soil.
  • the roller for example as a row pre-compaction roller of a tillage combination for spreading seed, can be designed in such a way that it predominantly has a high, easy passage of soil and the required reconsolidation and leveling of the soil in the necessary areas.
  • the roller has at least a first intermediate ring with a first diameter and a first width and at least one second intermediate ring with a second diameter and a second width, wherein the first diameter is smaller than the second diameter and/or the first width is smaller than the second width.
  • the intermediate rings can be arranged coaxially to the compression rings and/or the supporting body. In a mounted state, the first intermediate ring is arranged closer to the supporting body in the radial direction than the second intermediate ring. This has the advantage that the first intermediate ring can allow a higher passage of soil than the second intermediate ring and the roller can be pulled more easily as a result.
  • the second intermediate rings which are arranged at a greater distance from the supporting body in the radial direction, offer the advantage of improved reconsolidation and leveling of the soil between the adjacent compaction rings, as a result of which an improved seedbed can be provided, for example.
  • the second intermediate rings may have a greater width than the first intermediate rings, thereby allowing a larger area to be recompacted and leveled between compression rings.
  • the first intermediate ring and the second intermediate ring can be made of the same or different material, for example plastic, metal and/or an elastic material.
  • a first intermediate ring can be made of plastic when the load is lower, and a second intermediate ring can be made of a more resistant metal due to the higher ground contact.
  • two intermediate rings with different diameters and/or different widths are arranged between two adjacent compression rings.
  • a first intermediate ring can be arranged close to the supporting body and a second intermediate ring can be arranged radially on the outside, overlying it.
  • the compression rings and/or the intermediate rings are non-positively and/or positively connected to the supporting body.
  • the supporting body can be designed in the form of a substantially cylindrical or profiled body, for example a tube, a profiled shaft and/or a square tube.
  • the compression rings and/or intermediate rings can be slid onto the supporting body in the axial direction.
  • the compression rings and/or intermediate rings can have a shape corresponding to the profile of the supporting body radially on the inside for the, in particular detachable, form-fitting connection with the supporting body.
  • the advantage here is the simplified assembly of the compression rings and/or intermediate rings on the supporting body and that the compression rings and/or intermediate rings can be arranged on the supporting body in a torsion-proof manner, whereby their rotational movement can be carried out more reliably and the functional reliability of the roller can be increased.
  • At least one, in particular circumferential, shoulder for receiving a first intermediate ring is formed laterally on the compression ring on the supporting body side.
  • the step can be stepped and forms a stop for the first intermediate ring in the axial direction and/or in the radial direction, in particular in the inward direction.
  • the shoulder and/or the first intermediate ring can be designed in such a way that, in an assembled state, a non-positive and/or positive connection can be formed between the first intermediate ring and the at least one shoulder, for example in the case of a compression ring arranged at the end of the roller, as a result of which the strength of the roller can be increased.
  • At least one, in particular circumferential, receptacle for receiving a second intermediate ring is formed radially on the outside of the compression ring.
  • the receptacle can be designed in the form of a groove, in particular a circumferential groove, on the side of the compression ring.
  • the receptacle can form a stop for the second intermediate ring in the axial direction and in the radial direction.
  • the receptacle and/or the second intermediate ring can be designed in such a way that, in an assembled state, a non-positive and/or positive connection can be formed between the second intermediate ring and the at least one receptacle, for example in the case of a compression ring arranged at the end of the roller, as a result of which the strength of the roller can be increased.
  • the first intermediate ring and/or the second intermediate ring is connected, in particular detachably, to at least one adjacent compression ring by a connecting element.
  • the connecting element can be designed in the form of a bolt or a rivet connection.
  • the connecting element can be connected to two adjacent compression rings, as a result of which a first and/or second intermediate ring arranged between the two compression rings can be mounted in a non-positive and/or positive manner between the compression rings.
  • the connecting element can contact the first and/or second intermediate ring, for example by pushing the connecting element through a corresponding opening in the respective intermediate ring, as a result of which a defined mounting position of the intermediate ring can be set.
  • a compression ring can laterally, in particular between the shoulder and/or the receptacles for the first and second intermediate ring, have at least one recess for at least partially accommodating the connecting element.
  • the strength, rigidity and functional reliability of the roller can be further improved by the connecting element.
  • the compression ring is composed of at least two half-shells, which can each be slipped onto the supporting body in the axial direction. Due to the half-shells, which are designed in particular symmetrically, a compression ring can be produced inexpensively and easily assembled.
  • a scraper is assigned to the first intermediate ring, in particular in each case, and/or a scraper is assigned to the second intermediate ring, in particular in each case.
  • the scrapers and scrapers can each be associated with an intermediate ring and at least partially protrude into an intermediate space between adjacent compression rings in order to be able to remove soil buildup from the respective intermediate space.
  • the clearers and scrapers can be arranged on the support frame.
  • the support frame is arranged behind the axis of rotation of the roller in the working direction, which means that shorter and therefore more stable scrapers and/or scrapers can be used.
  • the scraper partially protrudes between the adjacent compression rings, but is arranged at a distance from the first intermediate ring, so that there is little frictional resistance.
  • a scraper on the other hand, can protrude further into the space between the compression rings and the second Contact the intermediate ring on the circumference or reach very close to it. As a result, the resistance during operation can be higher than with the scraper.
  • the number of scrapers required can be reduced and thus the overall friction can be reduced, so that the roller can be pulled more easily.
  • At least one bearing device is preferably arranged at the end of the supporting body, which has an adjustable axial prestressing force which enables an essentially axial force to be applied to the compression rings and/or intermediate rings.
  • the support body with the compression rings and intermediate rings can be rotatably supported on the support frame by the bearing device.
  • the stability and functional reliability of the roller can be increased by applying an axial prestressing force to the compression rings and/or intermediate rings.
  • the roller has a plurality of supporting bodies, each mounted on a base frame, which are connected to one another in particular in a foldable manner.
  • the roller can be made more compact, as a result of which safe road transport that conforms to the regulations can be made possible even with large working widths.
  • the invention further relates to an agricultural implement for tilling the soil and/or spreading granular solids in the form of fertilizer and/or seed with at least one roller as described and configured above.
  • the agricultural device can be designed in the form of an order combination for seed application, which, for example, a number of Has sowing coulters, each one sowing coulters can be assigned to a compression ring.

  • the device can have a chassis made up of several ground-engaging means such as tires arranged next to one another, which essentially cover the working width of the device and carry the weight of the machine and can recompact and level the soil.
  • the roller, in particular the compression rings, following the device can each have coulters for introducing a seed into the ground behind the roller.
  • a distance or gap can be formed between the ground engaging means. This gap can lead to the soil being reconsolidated to a lesser extent between the soil intervention means during tillage and a dam made of soil can be created in each case.
  • a second intermediate ring can be assigned to each of the gaps between two ground-engaging means, while first intermediate rings can be assigned to the remaining working area. This has the advantage that the area between the ground engaging means can be reconsolidated and leveled by the second intermediate rings, and the remaining areas have first intermediate rings, as a result of which an improved seed bed can be created with a roller that pulls more easily.
