AGRICULTURAL TOOL HOLDER Russian patent published in 2024 - IPC A01B51/04 A01B39/24 A01B63/10 A01B63/24 A01B63/32 

FIELD: agriculture.

SUBSTANCE: agricultural tool holder (100) comprises a central frame (TC) holding a three-point coupling system (P) for connection to an agricultural tractor and accommodating all hydraulic and electrical parts used to actuate articulated components of tool holder (100) and tools configured to be mounted on tool holder (100). Agricultural tool holder (100) comprises at least one lateral frame (TL) capable of sliding towards or away from the central frame (TC). Central frame (TC) has axis of symmetry (Y) and comprises a pair of parallel tubular beams (1) passing along direction perpendicular to axis of symmetry (Y) of central frame (TC). Side frame (TL) comprises a pair of parallel bars (10) adapted for insertion and sliding movement inside tubular beams (1), which support telescopically side frame (TL). At least one actuator (50) is installed on the central frame (TC), which is made with possibility of providing movement by means of a push of the said at least one side frame (TL). Pair of bars (10) is rigidly connected by means of two intermediate beams (11 and 12), which are inserted between bars (10) and are screwed to them. One beam (11) is matched with one end of bars (10), and one beam (12) is matched with the centre of bars (10) so that bars (10) can enter section (10a), which is half their length, inside tubular beams (1) central frame (TC).

EFFECT: providing ease and efficiency of maintenance of the machine with higher stability of assembly of tractor/tool with higher safety during operation; modularity and easy integration of auxiliary devices without increase in volume in comparison with the basic configuration of the machine; machine stability also in fully extended configuration; possibility of mechanization of work in unfavourable agricultural regions; possibility of installation with a front coupling with a tractor without deterioration of its stability and without damage to parts of the front axle; possibility of using tractors of low power and smaller dimensions with positive consequences in terms of sustainable economic development and agronomic development; manoeuvrability on non-ploughed areas and in reduced spaces; visibility of working tools with lower stress for the operator and higher efficiency.
