Pick-up press for agricultural stalks

The innovation concerns a pick-up press for agricultural Straw goods with all the necessary drives from one located in the front part of the press housing Main gear is derived by shafts and gear drives, the shaft of which runs transversely to the machine's longitudinal axis the drive crank for the plunger carries at its free end and from which via bevel gears and an additional The output shaft is used to drive the cross conveyor and binding device.

Pick-up presses are known from practice in which all the necessary drives are from one in the front part of the press housing arranged main gear can be derived. They have been shown to be beneficial for years since 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 power flow. Of this Main gears are used to drive various machine parts, such as the plunger, cross conveyor, binding mechanism and pick-up. In known presses, they are driven by chains, V-belts and cardan shafts, most of which are used in large numbers will. The maintenance of these transmission elements is time-consuming. Chains and universal joints must be lubricated, chain and V-belt tensioning wheels must be readjusted. Any play caused by loose chains affects the Function of the press, in which there is an extremely precise coordination between the movements of the piston, its inner cross conveyor and binding mechanism arrives. The chain load when driving a cross conveyor is very unfavorable, as with the usual four-jointed design

two acceleration peaks are passed through each revolution, which load the chain intermittently. the There is great wear and tear on chains and V-belts. The large diameters required for safe power transmission require space-consuming constructions outside the actual press housing.

In order to avoid these disadvantages, presses have become known in which the power transmission is driven to all Machine parts are made exclusively by shafts and gear drives. In such presses, the ring gear the main gear has two ring gears, of which the outer one in a known manner with the one coming from the flywheel Drive pinion meshes while the other two drives are removed from the inner ring gear. Such gears however, they are expensive and complicated to manufacture. They are also not very robust.

The present innovation is therefore based on the problem of creating a pick-up press of the type described in more detail at the beginning to create the requirements to be placed on them, especially with regard to simple manufacture and a low susceptibility to failure satisfactorily.

This is achieved according to the invention in that the main gear consists of a ring gear with a single ring gear, with which a single drive bevel gear and a single output bevel gear mesh. The output bevel gear is advantageous Connected to the countershaft via an intermediate shaft and two rubber disk clutches.

In the following, the innovation will be based on an exemplary embodiment and two of these schematically and partially in perspective Representative figures are explained in more detail. It shows:

While the rear housing part serves as a pressing channel 2, the drive for the piston 3 is housed in the front area. With 4 is the name of the pick-up with tines, to which a cross conveyor table (5) is connected. The task of conveying the goods The cross conveyor (6) falls into the baling channel and is driven via a countershaft (7) and associated gear pairs will. The drive shaft (8) for the binding device, not shown, is also in rotary connection with the shaft (7) the press. The torque taken from the tractor is converted into the Main gear (11) introduced into the press. At the free end of the transverse shaft (12) of the gearbox (11) is the output crank (13) arranged for the plunger (3). Also on the shaft (12) in front of the crank (13) and thus outside of the gearbox housing is, not shown, a sprocket for driving the AufSammlers (4) attached. In the gearbox of the gearbox (11) itself a ring gear (15) is attached to the shaft (12) and has only a single toothed ring (16). Both the bevel gear (17) of the drive shaft (18) coming from the flywheel (10) mesh with this ring gear (16) as well as the bevel gear (19) of the AbtridBwelle (20), which has a Intermediate shaft (21) and rubber disk couplings (22 and 23) as well as a bevel gear (24) with the countershaft (7) are connected.
