Definitions

  • the invention relates to a tool for manually rotating a Gutbearbeitungs- and / or Gutrionelements an agricultural harvester, with a lever arm and an associated, releasably and torque-coupled with the Gutbearbeitungs- and / or Gut influenceelement coupling element spaced at a distance from the axis of rotation of Gutbearbeitungs- and / or Gut busyelements can be attached.
  • US 4 171 653 A describes a tool for rotating a pulley.
  • the tool includes a disc equipped with several tube extensions. Through the tube extensions screws are used, which are inserted into suitable, spaced from its axis of rotation holes of a mounting flange which is fixed to an axis to be rotated.
  • the disc is rotated by a manually handled lever. Again, a separate flange is provided to attach the tool can.
  • the object underlying the invention is seen in a to provide improved tool for manually rotating a Gutbearbeitungs- and / or Gut oppositionelements an agricultural harvester, which does not limit the freedom in the design of the attachment of Gutbearbeitungs- and / or Gut occasion listening.
  • the invention relates to a tool with a lever arm and a coupling element, which is attachable at a distance from the axis of rotation of Gutbearbeitungs- and / or Gut busyelements.
  • the tool is thus coupled to the Gutbearbeitungs- and / or Gut dividedelement or a torque-connected element connected thereto at a distance from the axis of rotation.
  • Many Gutbearbeitungs- and / or Gutrionetti are driven by a pulley.
  • the coupling element of the tool is placed on the edge of the pulley.
  • the torque of the tool is transmitted through the existing drive connection from the pulley to the Gutbearbeitungs- and / or Gut busyelement.
  • a suitable tool can be designed so that it can be used with as many different pulleys of different model series and / or makes of harvesting machines.
  • the tool Since the tool is placed on a pulley, proves an embodiment as particularly favorable, because universally applicable, in which a first holding finger on the outside of the pulley or a drive belt disposed thereon, while a second holding finger bears against the inside of an axially projecting edge of the pulley.
  • tools with a lever arm and protruding fingers are known per se (DE 199 36 033 A), but for a very different purpose, namely for opening compressed gas cylinders.
  • the drive belt between the first holding finger and the pulley prevents the first holding finger from deforming the pulley. If two holding fingers are arranged on the inside and / or outside of the pulley, the tool is particularly well suited for low-backlash movement of the pulley in both directions of rotation.
  • the holding finger disposed on the outside of the pulley may be selected to be longer than a holding finger disposed on the inside, thereby reducing the pressure on the pulley.
  • the retaining fingers are attached to a holding plate connected to the lever arm.
  • the latter can be connected on its surface facing away from the fingers with a mounting plate, which in turn has a extending into the tubular lever arm portion. If the retaining plate can be separated from the fastening plate, for example by a screw connection, it is possible in the event of damage to replace the retaining plate with the retaining fingers.
  • the retaining fingers can be releasably attached to the retaining plate. If the mounting plate is separable from the lever arm, the latter can also be used for other purposes, such as an extension for a window cleaner.
  • a harvester 10 in the form of a self-propelled combine harvester shown in Figure 1 is supported on front driven and rear steerable wheels 12 and 14, respectively, and has a driver's cab 16 from which it can be operated by a driver.
  • a forage harvester a baler, a stationary threshing machine, a trial threshing system or the like could also be considered.
  • a grain tank 18 connects at the rear, which can deliver good discharged into it via an emptying tube 20 to the outside.
  • the grain tank 18 rests on a frame 22, in the supplied good on the way via a threshing drum 24, a concave 26 and a beater 28 is decomposed into its large and small components.
  • the threshing cylinder 24 is rotated by a pulley 56, around which a drive belt 58 driven by the main motor 64 is rotated.
  • a further separation of the harvested Guts is performed, which finally promoted the threshed Gutanteil in the grain tank 18, the large Erntegutmaschine be placed on the shaker 30 on the ground and light components are also blown from the screens 34 to the ground by means of a blower 36.
  • On the floor lying or standing Good is fed via a feeder 38 and a stone trap 40 of the threshing cylinder 24 after it has been picked up by a Erntegutbergungsvorraumettilement not shown from the ground.
  • a tool 42 according to the invention is shown in FIG. It comprises a relatively long lever arm 44 (for example, about 1 m long), at the first end of a handle 46 is attached.
  • a holding plate 48 is arranged, the three transverse to the longitudinal axis of the lever arm 44 oriented, cylindrical holding fingers 50, 52, 54 holds, which project perpendicularly from the holding plate 48.
  • the holding fingers 50-54 which are arranged approximately on an equilateral triangle, serve as a coupling element for producing a detachable, torque-locking connection with the threshing drum 24, have longitudinal axes oriented parallel to one another, are inserted into corresponding bores in the holding plate 48 and are preferably exchangeable.
  • the handle 50 facing the arranged on the imaginary extension of the longitudinal axis of the lever arm 44 first retaining finger 50 is longer than the other two, second retaining fingers 52, 54 which are arranged symmetrically to the longitudinal axis of the lever arm 44.
  • the tool 42 is shown in the position in which it is placed on the pulley 56.
  • the pulley 56 is arranged coaxially with the threshing drum 24 and connected in a torque-locking manner with it.
  • the drive belt 58 is set to drive the threshing drum 24.
  • the tool 42 rests with the holding plate 48 against an outer, axially projecting edge 66 of the pulley 56.
  • the longer (first) retaining finger 50 rests on the drive belt 58 from the outside, while the two shorter (second) retaining fingers 52, 54 abut against the edge 66 from the inside.
  • the lever arm 44 extends from the pulley 56 approximately radially outwardly.
  • the retaining plate 48 is connected by screws 62, which are screwed into the retaining plate 48 in a thread, with a fastening plate 60 arranged on the side opposite the retaining fingers 50 - 54, which in turn is inserted into the tubular lever arm 44 extending portion which is secured in the lever arm 44 by screws.
  • the tool 42 provides an easily releasable torque-locking connection between the handle 46 on the one hand and the pulley 56 on the other hand.
  • the operator can shut off the main motor 64 when the threshing drum 24 is clogged, drivingly disconnect the drive belt 58 from the main motor 64 by means of a clutch and place it in front of the pulley 56 of the threshing drum 24 on the ground.
  • the shorter retaining fingers 52, 54 come on the inside of the edge 66 of the pulley 56 and the longer retaining finger 50 comes on the outside of the drive belt 58 for concern.
  • the operator holds the tool 42 on the handle 46 and thus rotates the pulley 56 counter and / or in the prevailing at harvesting direction until the jammed between the threshing drum 24 and the concave 26 crop is removed forwards or backwards from the threshing.
  • the operator can manually remove the crop at the front of the threshing drum 24. Subsequently, the tool 42 is removed again, stowed at a suitable location, for example in the driver's cab 16, and the harvesting operation resumed.
