SEEDER FOR SPREADING SUBSTANCES FOR REGULATING SOIL CHARACTERISTICS, FERTILIZERS AND SEEDS Russian patent published in 2023 - IPC A01C7/00 A01C15/00 A01B73/06 A01B63/16 

FIELD: agriculture.

SUBSTANCE: seeder for spreading substances to regulate the characteristics of soil, fertilizers and seeds consists of two spreading modules (1), each of which is equipped with a hopper (11) and installed on top of conveyor belts and a chassis (12), of wheel pairs (2), of trailed devices (3) with a jacking support (32) and a trailer end (31). The towing device (3) has articulated joints (33) on the modules (1) aligned centrally at the front (34) and with a trailing end (31) accompanying the movement of the modules (1) during the transition from the working position to the transport position and back. The seeder contains a mechanism for transferring (4) modules (1) from the working position to the transport position, consisting of a hydraulic drive located horizontally and its piston facing backward parallel to the direction of displacement of the agricultural implement. The end of this piston is connected with the possibility of transmitting rotation to a central pin that connects and articulates the arms of the chassis (12) of the spreading modules (1), adjacent on the sides, which, through pairs of lateral adjustable connecting rods, are articulated with the lower and upper pins on the connecting flange of the hydraulic drive, aligning it centrally in the required position, when making adjustments with the hydraulic unit (48) and the control device. The seeder contains a mechanism for blocking the modules (1) in the working position, blocking the side adjacent guide beams of the chassis (12) of the modules (1), installed on one of the modules (1) and consisting of a hydraulic drive, regulated by a hydraulic unit (52) and a control device, connected to a rod hinged at one end or locking rod, with the other end hinged to locking rods or locking guides passing through holes or connecting members across said guide beams, the ends or locking pins of which are connected to rigidly fixed brackets, attaching one module (1) to another module (1). The seeder contains a mechanism for rotating the wheel pair units (2), installed under a rigidly fixed base, screwed to the corresponding chassis (12) of the module (1), consisting of a hinged stand capable of rotating and performing translational rotational movement under the influence of a hydraulic drive, adjustable hydraulic unit (63), rotation sensor and control device, said stand installed on top of the rocker arm (65) installed between the turning axles of the wheel pairs (2) and the specified device that ensures their movement when turning.

EFFECT: operational and functional improvement of agricultural implements.
