MULCHING APPARATUS FOR PROCESSING THE STOVER STANDING IN THE FIELD, WITH AN ADJUSTABLE POSITION AND/OR FORCE OF PRESSING TO THE SOIL Russian patent published in 2021 - IPC A01D34/835 

FIELD: agricultural machines.

SUBSTANCE: group of inventions relates to agriculture, namely to a mulching apparatus for installation on the harvesting attachment of a self-propelled harvesting machine, a harvesting attachment of a self-propelled harvesting machine with such a mulching apparatus, and a self-propelling harvesting machine with such a harvesting attachment. The mulching apparatus for installation on the harvesting attachment of a self-propelling harvesting machine includes at least one processing implement driven by a drive for crushing stover, the fastening mechanism of the processing tool configured for adjusting the position thereof, installable or installed on the harvesting attachment, and means of controlling the position of the fastening mechanism relative to the harvesting attachment and/or the force of pressing the fastening mechanism to the soil in the harvesting mode. The means of controlling the position and/or the force of pressing the fastening mechanism to the soil include a power-driven actuating element configured to be connected, or connected, with the control in order to control the actuating element. The control is configured to supply and actuate by signals from the control of the height of the harvesting attachment and/or control of the advance of the harvesting machine whereon the harvesting attachment is installed, and/or the speed sensor for recording the advancing speed of the harvesting machine whereon the harvesting attachment is installed, so as to automatically force the actuating element to bring the mulching apparatus relative to the harvesting attachment to a non-working position lifted relative to the working position taken in the harvesting mode, and/or send the command to lift the harvesting console to the control of the height of the harvesting attachment, if the harvesting attachment is lifted off the ground and/or the harvesting machine is moving backwards and/or the harvesting machine does not reach the set minimum advancing speed.

EFFECT: variation in the pressing force in order to adapt to the corresponding conditions of the soil and the harvested crops, setting of the pressing force greater than as set by the force of the weight of the mulching apparatus, as well as exclusion of unnecessary processing of the headland by the mulching apparatus and exclusion of damage to the mulching apparatus, are provided.
