Definitions

  • the present invention relates to an agricultural implement, the working depth of which is adjustable, and to a method for adjusting the working depth of an agricultural implement.
  • agricultural implements for soil cultivation can comprise a plurality of tilling tools, such as harrow tines, discs, cultivator tines, levelling implements, plough blades, seed furrow openers, sowing shares, seed furrow closers, etc.
  • tilling tools such as harrow tines, discs, cultivator tines, levelling implements, plough blades, seed furrow openers, sowing shares, seed furrow closers, etc.
  • Some agricultural implements have one or more transport wheels, which can be adjustable between a transport position, in which the transport wheels bear against the ground and the tools are elevated from the ground, and a working position, in which the the transport wheels are elevated from the ground and the tools engage with the soil.
  • the height adjustment of the transport wheels relative to the frame of the agricultural implement is usually realized with the aid of one or more hydraulic cylinders.
  • R example, one or more wheels or surface compactor rollers .
  • One object is therefore to provide a simplified agricultural implement.
  • an agricultural implement for soil cultivation comprising a main frame, a side section frame, which is rotatable relative to the main frame, at least one transport wheel, at least one tilling tool, at least one ground- contacting depth holder, associated with the side section frame, for controlling a working depth for the said tilling tool, and a first actuator, for controlling a height position for the said transport wheel relative to the main frame, or for controlling a height position for the said depth holder relative to the main frame.
  • the depth holder is connected to the transport wheel, so that both the height position of the depth holder and the height position of the transport wheel are simultaneously controllable by the said first actuator.
  • main frame is meant the frame which essentially defines the shape and extent of the agricultural implement. It will be appreciated that the main frame can comprise a number of parts which can be moved relative to one another, such as side sections or sections which are separated in the longitudinal direction .
  • actuator is meant a motion-generating device, such as a hydraulic or pneumatic cylinder. It will be appreciated that an actuator can comprise, for example, one or more parallelly or serially connected cylinders of this kind.
  • the agricultural implement can be configured just for soil cultivation, such as a cultivator, harrow or plough, for soil cultivation and feed-out of material (seed, fertilizer, pesticide) , or just for feed-out of material.
  • connection between transport wheel and depth holder can be direct, for example in the form of a coupling between the respective wheel axles, and/or indirect, for example in the form of a coupling between a frame which supports the transport wheel or the depth holder .
  • An agricultural implement according to the above is simplified, since it only requires one actuator for controlling the height positions of both the transport wheels and the depth holder. There is thus also a potential for reducing the production cost.
  • the transport wheel can be suspended from a transport wheel frame, which can be movable relative to the main frame.
  • the depth holder can be suspended from a depth holder frame, which can be movable relative to the therewith associated side section frame .

  • the mechanical coupling can engage with at least one of the transport wheel frame and the depth holder frame via a joint which allows rotation about at least two axes.
  • the transport wheel frame can be connected to the depth holder frame by a hydraulic or pneumatic connection .
  • a hydraulic or pneumatic connection allows greater freedom in the positioning of a second actuator, and thus an agricultural implement with greater width can be provided, compared with that which is allowed by a mechanical coupling between the depth holder and the transport wheel frame.
  • At least one second actuator can be arranged to act between the side section frame and the depth holder frame .
  • the second actuator can comprise one or more parallelly connected and/or serially connected cylinders .

  • the first and second rotational directions can be substantially the same. According to another embodiment, the first and second rotational directions can be substantially opposite .

  • the said first actuator can be activated for adjustment of one of the height position of the transport wheel relative to the main frame and the height position of the depth holder relative to the main frame, and wherein the other of the height position of the transport wheel relative to the main frame and the height position of the depth holder relative to the main frame is adjusted with the aid of a second actuator which is coupled as master or slave to the first actuator.

  • the depth holder is connected to the transport wheel, so that both the height position of the depth holder and the height position of the transport wheel are simultaneously controllable by the said actuator.
