Abstract
The round baler for cut stalk crops with a hinge-type pressing chamber comprises an inlet opening for the stalk crops and a tying arrangement for the completed bale, as well as a pick-up device for the stalk crops with a feed drum which is disposed between the pick-up device and the inlet opening and whose length corresponds to the width of the bale to be tied, as well as a cutting device which is provided in the feed channel and includes a plurality of pivotally supported knives which in their cutting position project into the feed channel and are arranged in at least one row, and which are held in their cutting position by means of spring-loaded knife levers and adapted to be pivoted singly or as a whole against the spring load up to a position in which they have no cutting effect on the stalk crops.
Claims12
A round baler for cut stalk crops comprising a hinge-type pressing chamber including an inlet opening for said stalk crops and a tying arrangement for the completed bale, a pick-up device for said stalk crops, a feed drum which is disposed between said pick-up device and said inlet opening and whose length corresponds to the length of the bale to be formed, a cutting device provided in a feed channel, wherein said cutting device includes a plurality of pivotally-supported knives which in their cutting position project into said feed channel and are arranged in at least one row, and which are held in their cutting position by means of spring-loaded knife levers and adapted to be pivoted against the spring load up to a position in which they have no cutting effect on said stalk crops, and wherein a sensor for sensing the internal pressure of said round bale is provided, said sensor controlling a pivoting device for said cutting device for pivoting said knives out of said feed channel when a predetermined value of said pressure is sensed.
A round baler for cut stalk crops comprising a hinge-type pressing chamber including an inlet opening for said stalk crops and a tying arrangement for the completed bale, a pick-up device for said stalk crops, a feed drum which is disposed between said pick-up device and said inlet opening and whose length corresponds to the length of the bale to be formed, a cutting device provided in a feed channel, wherein said cutting device includes a plurality of pivotally-supported knives which in their cutting position project into said feed channel and are arranged in at least one row, and which are held in their cutting position by means of spring-loaded knife levers and adapted to be pivoted against the spring load up to a position in which they have no cutting effect on said stalk crops, and wherein a measuring device for measuring the diameter of said round bale is provided, said measuring device controlling a pivoting device for said cutting device, for pivoting said knives out of said feed channel when a predetermined value of said diameter is sensed.
A method of forming a round bale using a round baler comprising a hinge-type pressing chamber including an inlet opening for said stalk crops and a tying arrangement for the completed bale, a pick-up device for said stalk crops, a feed drum which is disposed between said pick-up device and said inlet opening and whose length corresponds to the length of the bale to be formed, a cutting device provided in a feed channel and including a plurality of pivotally-supported knives which in their cutting position project into said feed channel and are arranged in at least one row, and which are held in their cutting position by means of spring-loaded knife levers and adapted to be pivoted against the spring load up to a position in which they have no cutting effect on said stalk crops, comprising the steps of winding said round bale from cut stalk crops, measuring during the winding operation the diameter of said round bale and/or the internal pressure of said round bale, and pivoting said cutting device out of said feed channel as a whole as soon as a predetermined threshold value of said diameter and/or of said pressure has been reached so that at least the outermost surface layer of said round bale is wound from uncut stalk corps.
