Definitions

  • the invention relates to a loader, in particular a front loader, with a loader arm and a tool which can be connected to it and which can be pivoted with respect to the loader arm via at least one servomotor and releasably connected to it via connecting means, and a device for connecting a tool to a loader arm either with or without the use of a tool holder, in particular a quick-coupling device, with respective connection devices for connection to connection means on the tool.
  • US-A-4,986,722 discloses a device for connecting a tool to a loader arm either directly or via a quick-coupling tool carrier, wherein the recess for quick mounting can be locked with a closed sleeve.
  • the object underlying the invention is seen in proposing a loader and preferably a device for connecting a tool to a loader, which can be universally combined with one another or can be converted for such universal use.
  • a linkage articulated according to claim 2 with two links causes a translation of the movement of the servomotor and thus a larger range of movement of the tool, which can be a shovel, a fork, a gripper and much more.
  • the servomotor can be a hydraulic motor, generally called a hydraulic cylinder, an electric or pneumatic motor, but also a mechanical linkage.
  • the preferably L-shaped design of one handlebar prevents the servomotor from reaching a dead center and allows additional influence on the travel of the linkage.
  • a device for connecting a tool to a loader arm which can also be retrofitted to existing loaders and tools, allows the conversion of a loader that can only be used on one side into a universally usable one Loader or a tool that can only be used on one side into a universally usable tool.
  • a loader 10 is shown as if it were connected to the chassis of an agricultural tractor, not shown, and carried by this.
  • the loader 10 contains a pair of upright support posts or support masts 12.
  • the rear end of a loader arm 16 is pivotally connected to the upper end of the support posts 12 by means of a bolt 14.
  • Each loader arm 16 initially extends forward and then downward from the associated support post 12, the downwardly extending portions of each loader arm 16 being connected to one another via a stiffening tube 18.
  • a shovel representative of tools 20 in general has a pair of connection means 22 or the like fastening elements or terminal blocks, which are located on the back and each of which contains a pair of spaced plates.
  • each connection means 22 is provided with a rear-opening rectangular recess and that the sleeve, which is assigned to each inner plate, is supported by an insert plate which can be detached from the recess and blocks it connected is; with regard to the details of the insert plate, reference is made to the content of US-A-4,986,722.
  • a hydraulic cylinder 26 for the loader arm 16 is inserted, which can be operated such that it raises or lowers the loader arm 16 between a lower position shown in solid lines and an upper position shown in broken lines can.
  • the piston rod end of an actuator 28 is used, which serves to pivot the tool 20 about the connecting bolt 24.
  • the servomotor 28 is a hydraulic cylinder which is usually referred to as this.
  • the tool 20 is shown in solid lines in a lower, maximum pivoting-back position in which the servomotor 28 is slightly less than completely closed or retracted.
  • the servomotor 28 is almost completely extended or opened in a raised, shown in broken lines and maximum tilting position of the tool 20.
  • the tool 20 of this exemplary embodiment of a loader 10 has a maximum return swivel angle “r” of approximately 17 ° and a maximum Tilt angle “d” of approximately 36 °, both angles being measured from a horizontal and the tipping angle being given in absolute values.
  • each linkage 30 includes a tool holder 32 which is upright in the lower position and which forms one of two opposite ends of a tool holder, and first and second links 34 and 36 or rocker arms and support links, each of which is a pair of spaced apart having parallel strut components are composed.
  • Each tool holder 32 contains spaced-apart parallel plates which are arranged on opposite sides and whose lower rear corner regions are hidden at the connection point 38 with the front ends of one of the loader arms 16, respectively.
  • the pair of strut components of the first link 34 is substantially L-shaped and has first ends on opposite sides of the loader arm 16 and is connected thereto by a bolt 40 which is received in a bush 42 shown in Figure 1, the Bush 42 is located at a distance behind the junction 38.
  • First ends of the strut components of the second link 36 are provided between second ends of the strut components of the first link 34 and are pivotably connected to them and the piston rod-side end of the servomotor 28 by means of a bolt 44 in a common joint.
  • the second ends of the strut components of the second link 36 are between the spaced plates of the tool holder 32 added and connected to this by means of a bolt 46, which can be seen through the bushes for receiving the bolt 27, sh. Fig. 1.
  • the tool holder 32 are interconnected by means of a cross clip 48 of rectangular cross-section, which is located in a lower front region of the tool carrier. This transverse clip 48 is received in the recess in each of the inner plates of the connection means 22, the insert plates which are used to block the recesses in the absence of the linkage 30, as is the case in FIG. 1, are removed.
  • each tool holder 32 forms a receiver 50 or saddle which engages over a bolt 52 which is located in an upper end region of the plates of the relevant tool holder 32.
  • Any known type of quick-locking device - not shown - can be used to releasably hold the tool carrier in position with the cross clip 48, which is located in the recesses of the connecting means 22, and the receptacles 50, which receive the bolts 52.
  • the tool 20 is shown in solid lines in a lower, fully tilted-back position in which the servomotor 28 is completely closed or retracted. In contrast, it is shown in a raised, fully tilted position in broken lines, in which the servomotors 28 are slightly less than fully open or extended.
  • the tool 20 according to this exemplary embodiment of a loader 10 has a maximum return swivel angle "r" of approximately 27 ° and a maximum tilting angle "d" of approximately 40 °.
  • Both the tool carrier and the quick-release device which may be provided on it are not absolutely necessary for the invention, since this essentially relates to the optional use of the rod 30.
