Definitions

  • the present invention concerns a laterally attached, rear wheel supported field chopper quick-release attached to the attachment frame joined to a tractor's lifting means and power transmission, said field chopper featuring, for quick-release, a power transmission receiving shaft and guiding means mounted on the side of the attachment frame, ie. to the left as seen from behind, for adjusting the attachment; and in which the height of the stubble is adjusted with the tractor's lifting means, which lifts/lowers the front end of the chopper via the attachment frame so that it corresponds to the desired stubble height; and in which power transmission to the flail shaft takes place via a belt transmission immovably mounted to the side of the chopper.
  • the present invention also concerns the attachment frame which makes the quick- release possible.
  • a common way of driving a field chopper is such that, using a chopper mounted laterally to a tractor, the wagon is blown full, after which the tractor driver must leave the cabin in order to release the chopper from the attachment frame.
  • the attachment frame is driven laterally to the chopper, at which point, in some known choppers, the traction pole of the attachment frame is locked to the chopper.
  • the driver still must leave the cabin and lower himself to attach at least the power transmission to the " chopper via the jointed shaft.
  • the cable.s and electric cords for controlling the discharge channel must be separately connected. During a work day, the tractor driver must often repeat these same routines dozens of times.
  • this attachment operation takes time and second, it has been found to entail, in practice, a particularly high risk of occupational hazard. So far, no solutions making a quick-release possible have been presented for a rear wheel supported field chopper. A great difficulty for a quick-release mechanism is caused by the fact that the attachment must allow for the chopp.er to swing sideways according to the terrain and must preseTve the current way of adjusting the stubble height. From the GB patent publication 1309822 is known a quick-release wheat or hay cutting apparatus, in which the stubBle height is 'adjusted with the tractor's lifting means. The structure of the cutting apparatus and.
  • the front wheel support allow for the quick-release power transmission to be permanently joined to the other attachment members, thus obviating the need for a moveable power transmission connection.
  • the quick-release solution presented in the said GB publication cannot be employed in connection with a rear wheel supported field chopper. This is because the structure presented requires that the axis line of the support wheels be close to the rotary axis of the lifting means .
  • the twisting attachment of the traction handle to the frame of the chopper can he achieved only with the said transverse shaft design.
  • swiweling movement of the chopper is made possible such ' that the counterpart is allowed to twist around a longitudinal axis at the end of the traction handle.
  • the twisting axes must be coincident.
  • Claim 4 is a fairly straightforward alignment and locking structure, which is most advantageously made parallel to the receiving shaft.
  • a method of realization of the attachment frame in accordance with Claim 8 is very advantageous in practice, as the attachment itself and the lateral shift of the traction hook can be controlled using only one hydraulic cylinder.
  • the most advantageous way of realization presupposes that the shift of the hooking apparatus is free, after the attachment has been carried out, for instance with a locking device, which locks the attachment apparatus into the attachment position.
  • the lateral shift of the traction hook makes it possible for the wagon to be loaded full. Practical use has shown that with a lateral shift of 40 cm the loading capacity is increased by several cubic meters. With the help of the lateral shift, the traction hook is exposed to the view for the duration of the attachment of the wagon, while usually the tractor must be driven to the attachment position blindfolded.

  • To the rear end of traction handle (8) is attached the attachment counterpart (9) such that it can twist around the shaft 10 in order for the chopper to be able to swing according to the shape of the terrain, Figures 1-3.
  • the telescopic joint shaft (11) is attached between the receiving shaft (15) of the power transmission situated in the attachment counterpart (9) and the driving roller of the belt transmission (4), as shown in Figures 3 and 4.

  • FIG 4 is shown the structure of the attachment counterpart (9).
  • the attachment counterpart (9) is joined immovably to the attachment frame (24), the structure allowing for swinging having been realized with the shaft (10).
  • the receiving shaft (15) of the power transmission and the bushing (21) are both perpendicular to the plate (17) .
  • Remote control of the discharge channel can be realized electrically, hydraulically or pneumatically.
  • the counterpart (9) features corresponding connectors such as an electric coupler (22) , into which the plug slides at the time the attachment is made.
  • the traction handle (8) can twist, at the side of the chopper, around shaft (7).
  • the slide (13) in the U-shape rail (6) diminishes the bending load to which shaft (7) is subjected.
  • the twisting; movement of the traction handle (8) is limited with appropriate members.
  • the attachment itself of the traction handle (8) resembles that used in known choppers; however, in known choppers the traction handle is always locked into a specific position during use and the adjustment only serves to preadjust the stubble height to a desired adjustment range.
  • the attachment frame (24) making the quick-release possible is attached to the three-point suspension device of the tractor via the forks (38) welded to the beam (23) .

By shifting the hook apparatus (26), also the attachment apparatus (27) can be shifted to an attachment position, ie. to the right-hand end of its travel, while the counterplate (33) pushes the shift bar (32), which is welded to the attachment apparatus (27) .
  • the first section (39) of the take-off shaft of the power transmission is attached to the take-off shaft of the angle gear (25) and the second section (29) is allowed to move inside the first section (39), in order to make an axial shift possible.
  • the second section (29) is attached with bearings to the attachment apparatus (27) .
  • the rails of the attachment apparatus (27) are parallel to the take-off shaft (29, 39), thus obviating the need for joints. Attachment is initiated as in known choppers, by attaching the fastening pivot (35) of the traction beam
  • the locking ridge (37) meets the plate (17) of the attachment counterpart "(9) and binds it laterally.
  • the guidance pivot (30) extends slightly further than the shaft (29) and aligns and locks the attachment accurately with the help of the bushing (21) of the counterpart (9).
  • the take-off shaft (29) extends to the inside of the receiving shaft and power transmission takes place with the help of the wedge-and- groove connection formed by the shafts.
  • the attachment apparatus (27) is locked into attachment position with an appropriate locking device (not shown), thus making it possible for the hook apparatus (26) to be freely used in adjusting the position of the traction hook.
  • the attachment apparatus (27) shifts under the traction of the spring (31) back to the off-position and the chopper can be removed in a reverse order from the one described.
