Abstract: The present invention relates to an agricultural spraying system, comprising: a reservoir configured to contain a product, the reservoir being connected to a first downstream duct configured to convey the product to a mixing area; a first tank configured to contain a clear liquid, the first tank being connected to a first upstream duct configured to convey clear liquid to the reservoir so that the clear liquid flushes the reservoir, forming a grey liquid; the system wherein the first downstream duct comprises an element configured to direct the grey liquid to at least a second tank connected to a second downstream duct configured to convey the grey liquid to the mixing area.

Abstract: The invention aims at a mobile robotic platform designed to move between two rows of vegetation, vines in particular, comprising four wheels, a hollow chassis defining a chamber, a platform, configured to close the chamber, a propulsion system housed in the chamber and configured to drive the wheels, said system comprising two traction geared motors, each connected to a pair of wheels, each pair being placed on an opposite side of the chassis and facing each other, at least one battery placed in the chassis, two chain systems, each connecting two wheels of the same pair, placed on the same side of the chassis, and each being configured to synchronize the rotation of the wheels on the same side.

Abstract: The invention aims at a mobile robotic platform comprising four wheels, a hollow chassis defining a chamber, at least one platform, placed above the chassis, with said platform defining at least two receiving areas, at least two masts connected to the chassis, the first mast protruding from the side of the chassis and the second mast protruding from the opposite side; the first mast extending into one of said receiving areas of said platform and the second mast extending into the other of said receiving areas of said platform; said platform being configured to receive on these receiving areas functional loads secured to said platform.

Abstract: The present invention relates to a bumper system of an agricultural machine, comprising: a plate pivotably connected to a chassis of the machine, movable between an initial position and a contact position; a bar movable between an initial position and an activation position; the bumper system being configured so that, in the event of the bar coming into contact with an obstacle, the bar moves from its initial position to its activation position, the bar actuating a control member configured to control an emergency sequence of the agricultural machine, the bumper system being further configured so that, in the event of the plate coming into contact with the obstacle, the plate pivots from its initial position to its contact position.

Abstract: The present invention relates to an autonomous agricultural machine comprising a frame having an inverted U-section, the autonomous agricultural machine having a roof and comprising a thermal engine system comprising an engine, the autonomous agricultural machine comprising a cooling system having an air circulation duct arranged in the upper part of the frame, directly under the roof, the duct having at least one opening to allow the intake of outside air into the air circulation duct and an upper air outlet to expel the hot air upwards, to the top of the roof, the cooling system also comprising a ventilation device to ensure air circulation in the air circulation duct, the air circulation duct being configured to allow the circulation of fresh air to cool the engine.

Abstract: The present invention relates to a closing device configured to close a can of phytosanitary product, the closing device having a bottom wall having at least three through openings, and a peripheral wall protruding from the bottom wall, a first opening being configured to be connected to an outlet of phytosanitary product allowing the phytosanitary product to be discharged from the can, a second opening being configured to open in a sealed manner into an inflatable membrane and to be connected to an inlet of a pneumatic circuit, so as to allow an overpressure to be generated in the can by the expansion of the inflatable membrane by the pneumatic circuit, a third opening being configured to be connected to an inlet of a hydraulic flushing circuit.
