Description

The invention relates to a pick-up press for agricultural stalks with in the front part of the press housing arranged main gear, which is mounted transversely to the longitudinal axis of the machine, with the main drive shaft via a bevel gear in meshing ring gear, which the Drive crank for the plunger carries. Ramming presses of this type have been used for years proved to be advantageous, as the usual drive from the tractor PTO shaft via a cardan shaft and a subsequent flywheel on the front of the press housing ensures the simplest flow of forces.

Various machine parts are to be driven by this main gear, such as plungers, cross conveyors, Tying mechanism and pick-up. In known presses, they are driven by chains and V-belts and cardan shafts, which are mostly used in a variety. The care of these transmission elements is time consuming. Chains and universal joints must be lubricated, chain and V-belt tensioning wheels have to be readjusted. Any play caused by loose chains affects the Function of the press in which there is an extremely precise coordination between the motion sequences of the piston, the inner cross conveyor (packer) and the binding mechanism arrives. The chain load when driving a cross conveyor is very unfavorable, since bii the usual four-articulated design two acceleration peaks are passed through with each revolution, causing the chain to intermittently is charged. The chains and V-belts are subject to great wear and tear. The one for safe power transmission ^ Required large wheel diameters require space-consuming constructions a.outside the actual press housing.

It has therefore already been proposed that the power transmission from the main transmission via two output shafts forward, one of which is a continuation of the main drive shaft while the other via a separate, arranged at the end of the crank shaft and outside of the baling channel Bevel gear is driven. This proposal failed to be in line with the market and at all functioning construction, because the output shaft, which the binding mechanism and the Has to drive pick-up with the high speed of the main drive shaft, d. H. rotates at 540 rpm and the reduction to the required operating speed of the driven units in a simple, open gear cannot be made. The proposal is also very complex and expensive extensive drive means for the height-adjustable pick-up ahead.

The object of the invention is to overcome the numerous disadvantages of the known drives for press constructions to eliminate and through the special design of the central main gear, the further ones Drive elements to be designed so simply that they only require a minimum of care and maintenance and are only subject to slight wear. The assembly of the drive elements should be simplified and the production of the press can be streamlined. In addition, outside of the press housing lying drive parts are avoided, which reduces the risk of accidents and the external shape of the Press is improved.

The invention is based on the knowledge that an advantageous overall press drive under exclusive Use of shafts and simple gear drives must be done. The drive can then be significantly simplified if it is possible to transfer the torques to all drive units to transmit two output shafts, which are discharged directly from the main press gear. the Main gears of all known presses have a reduction of 540 to 100 rpm. Became attack the output shafts on the main drive ring gear of the ring gear, so they would inevitably have to Revolve at 540 rpm. This output shaft speed would be much too high to reduce the gear reduction for the ones to be driven Press units with simple, open
