Abstract

Round balers are used to produce round bales for agricultural stalks (grass-hay-straw). For the production of silo bales, presses with combined wrapping devices are used in particular, where the pressing and wrapping takes place in one operation. Integrated cutting units are mostly standard (cutting lengths theoretically approx. 45mm). Starting from a round-bale-baler-wrapper combination, through the construction of a straw chopper (2) for agricultural stalks, it is possible to cut much shorter (theoretically cutting length 15mm), which makes it possible to pack chopped silage into round bales in one operation. The production of chopped bales has the advantage that by pressing chopped stalks, significantly higher densities can be achieved, which results in better silage quality. Construction of the straw chopper (2) installed lengthways (transversely to the direction of travel). The straw material is picked up from the ground by means of a pick-up next to the chopper-baler-wrapper combination. Due to the side straw material pick-up (3), the straw material is loosened by the feeding of the straw chopper (2) by means of a conveyor belt (4), which results in a more even loading of the straw chopper (2). By feeding the chopped material to the pressing chamber (1) by means of a pendulum movement of the discharge spout (6), an even loading of the pressing chamber (1) is achieved. Furthermore, an optimal overview of the receiving device (3) is given, since a good overview is available from the tractor cab. For transport, the straw material pick-up (3) (pick-up conveyor belt), attached to a lifting arm, is folded up vertically.

Description

The invention relates to an agricultural round baler for stalks (grass / hay / straw)

Round balers (1) are used for the production of round bales from agricultural stalks. In particular, presses with an integrated cutting mechanism are used for the production of silo bales. The object of the invention is to produce round bales with the object that the cutting unit is replaced or connected upstream by a chopper unit (2). The cutting rotor is only used to transport the short-chopped stalks into the baling chamber. By setting up a chopping unit (2) in front of the round baler (1) transversely to the direction of travel, the crop is picked up at the side in front of the press. A conveyor belt (4) is connected downstream (3 + 4 also called belt swathers) by means of the pick-up (3) (the pick-up of crop material from the ground), which transports the crop material into the chopper unit (2). The pick-up and conveyor belt, which is attached to a lifting arm, is positioned vertically to the transport position (drawing no. 2). The briefly chopped stalks are transported from the chopper unit (2) into the chute (5) through the discharge chute (6), which is designed in this way, by means of an eccentric drive (7) with left and right movements. This ensures that the round baler (1) is fed evenly with the chopped material.

Claims (4)

1. Chopper-press-wrapper combination, characterized in that the chopping unit 2 (drawing 1) is located longitudinally (transversely to the direction of travel) in front of the round baler. 2. Chopping-press-winding combination characterized 3 (drawing 1) that the straw material recording from the ground by a pickup attached to the lifting arm is marked 3 (drawing 1) straw material recording is located next to the chopping-press-winding combination. 3. Chopper-press-wrapper combination characterized 4 (drawing 1) that the straw-good from the pick-up 3 (drawing 1) is fed to the chopping unit with a conveyor belt. 4. Chopper-press-wrapper combination characterized 6 (drawing 1) that the ejected chaff-good is thrown through the discharge chute 6 by means of a pendulum movement (left-right) into the chute 5 and fed to the compression chamber.
