A feeding device for feeding coating and/or cleaning agents to a sprayer has an annular structure and includes an annular plate, a plurality of connection modules, a plurality of function modules and a plurality of inlet modules. Each connection module is removably mounted to bear against one side of the annular plate. Each function module is removably mounted on an outer face of a connection module. Each function module is fluidically coupled to the connection module onto which same is mounted. Each inlet module is removably mounted on an inlet face of a connection module. Each inlet module carries fluidic coupling elements accessible on a face of the inlet module, oriented opposite the connection module on the inlet face of which same is mounted.

The present invention aims at a selective liquid spraying unit comprising a liquid inlet, a spraying nozzle, a delivery channel extending from the liquid inlet to the nozzle, possibly through an obstructable passage, and possibly a pneumatically operated valve with a pneumatic chamber delimited by a membrane and supplied by a second pneumatic inlet, a first pneumatic inlet connected to the delivery channel via a check valve, the membrane being movable between a first position causing the obstruction of the obstructable passage and a second position causing the release of said obstructable passage, so that an air supply via the first pneumatic inlet allows the delivery channel and the nozzle to be purged, and a spraying system including one or more spraying units.

The invention relates to a process for painting a workpiece using a painting robot including a robot arm equipped with a paint spraying device, the process including, an operation S 1 of modeling a realistic 3D model corresponding to the workpiece as deformed and positioned in a paint cell, the realistic 3D model including paint trajectory information suitable for the workpiece as deformed and positioned in the paint cell, and a paint spraying operation S 2 during which the paint spraying device is moved along the paint trajectory opposite the workpiece.

Apparatus for cleaning narrow root crops including a roller device with two rotatable rollers forming a separating crop inlet, a separating track, a coarse material outlet, a fine material outlet, and a roller gap, and a conveyor downstream of the roller device. The separating track is formed by the top of the rollers and the fine material outlet is located below the roller gap. The coarse material outlet is at the end of the separating track opposite the separating material inlet. The roller gap is large enough to allow the narrow root crops to pass through to the fine crop outlet and small enough to retain coarse material that has a minimum dimension greater than the maximum root diameter, and transport it to the coarse material outlet. The conveyor is below the roller gap at the fine material outlet and receives all narrow root crops passing through the roller gap.

An injector for a multi-component coating product spraying device, the injector having a longitudinal direction, the injector having an inlet. The injector has a plurality of outlet orifices, the injector being adapted to be supplied with a component product at the inlet, so that the component product exits the injector through the outlet orifices, each outlet orifice forming a given angle with respect to the longitudinal direction of between 10° and 90°, preferably between 30° and 90°. The invention also describes and claims an associated spraying device.

The present invention relates to a valve comprising a body having a central conduit accommodating a sliding piston and a diaphragm connecting the body to the piston surrounding the piston. The diaphragm comprises an annular membrane for separating the central conduit from a pressurized fluid chamber. The body comprises an annular cradle, which extends radially between the central conduit and a peripheral annular ring of the diaphragm. The diaphragm takes an initial shape, where the annular membrane is distant from the annular cradle, when the piston is in a distal position and no overpressure occurs. The diaphragm is elastically deformed into stretched shapes, where the annular membrane comes in contact and mates with the annular cradle, under the effect of an overpressure occurring in the pressurized fluid chamber.

A coating product spray gun including a body, a spray head, and a spray nozzle. The gun includes a ring connecting the spray head and the body, and an angular holding element of the angular position between the ring and the spray head. The gun includes a locking element movable between a locking position, wherein it locks the angular position of the ring relative to the body, and a release position, wherein it allows angular rotation of the ring relative to the body. An associated ring, assembly and method are also described and claimed.

The present invention relates to a method for calibrating an agricultural spraying machine comprising a plurality of spray nozzles arranged on the spray boom, at least one optical sensor and a control system, each optical sensor of said at least one optical sensor having a field of view comprising sectors, each of the sectors being associated with a spray nozzle, the control system being configured to control the plurality of spray nozzles as a function of images acquired by the optical sensors, the calibration method comprising, for an optical sensor, an automatic association implemented by the control system of each sector of the field of view of the corresponding optical sensor with a spray nozzle of the plurality of spray nozzles.

The present invention relates to a pump assembly, more particularly for a coating fluid, comprising a motor and hydraulics, the motor comprising an air inlet, the hydraulics comprising at least one pumping system, the motor being able to drive the at least one pumping system by means of a hydraulic system, characterized in that the pump assembly comprises at least one air passage arranged so as to allow thermal exchanges between the hydraulic system and the at least one air passage, the at least one air passage being able to be supplied with air by an air source, the at least one air passage being fluidly connected opposite the air source to the air inlet of the motor.

The present invention relates to a Venturi powder gun comprising a body, an injector of drive gas and an ejector of a mixture comprising the powder product, mounted in the body. The body defines a duct for circulating the mixture, upstream of the ejector. The injector and the ejector are straight and extend respectively along an injector axis and an ejector axis, which coincide when the powder pump is in the assembled configuration. Means for indexing the position of the ejector within the pump body, in rotation about the ejector axis, make it possible to align an inlet of a suction chamber with the mixture circulation duct defined by the pump body.
