A pipe for the aeraulic transport of a loose-fill insulation product for a machine for blowing the insulating product, the pipe extending along a longitudinal main elongation direction and including at least one cylindrical wall which delimits a space configured for the circulation at least of the loose-fill insulating product, wherein, in the pipe, the cylindrical wall includes a plurality of sections, at least two of the sections each including at least one evacuation orifice so as to form at least two perforated sections, the pipe including at least two shutoff devices that are movable in translation along the longitudinal direction about the cylindrical wall, each of the shutoff devices being able to cover specifically one of the perforated sections.

The present invention provides a protective wear cover which may be utilized in a metering device housing to protect the housing in an area which may be subjected to high impact by product flow. The protective wear cover may be installed inside the metering device housing at the venturi induction zone. The protective wear cover may be manufactured from a highly wear resistant material. The shape of the protective wear cover may be suited to conform to the metering device housing in the protected area to ensure a tight fit and negligible effect on air flow. This protective wear cover may therefore serve as a sacrificial barrier which prevents wear on the metering device housing and may be periodically replaced when worn. Replacing the protective wear cover negates the need to replace the whole metering device housing.

A particulate material delivery system for an agricultural implement including, an inductor box configured to receive particulate material from a tank, the inductor box including, an inductor segment comprising an air bypass channel extending through a particulate material supply chamber, wherein the particulate material supply chamber is configured to receive the particulate material for distribution to at least one row unit, and the air bypass channel is configured to guide airflow through the particulate material supply chamber without interacting with a flow of the particulate material through the particulate material supply chamber, and an airflow control device in communication with the inductor segment and configured to control the airflow through the air bypass channel.

A material handling apparatus is described comprising a material press body having an inlet and an outlet; a power source for generating an airstream into the inlet of the material press body and through the outlet of the material press body, wherein the airstream captures and feeds a supply material into the material press body; a plurality of press augers for capturing and manipulating the supply material into the material handling apparatus; and a drive system connected to drive and control the plurality of augers.

A powder feed assembly comprises a powder hopper, a motor, an auger housing, an auger, a porous gas-permeable powder filter, a carrier gas inlet, an auger sleeve, and a powder hose. The auger housing receives a powder from the opening in the hopper floor into a powder chamber defined in the auger housing. The auger is selectively rotatable to propel the powder from the powder chamber past the distal end of the auger and into the auger sleeve. The carrier gas inlet introduces carrier gas into an inner chamber of the auger housing. The wall of the auger sleeve allows at least some of the carrier gas to flow or permeate into the internal bore of the auger sleeve to pick up and carry the propelled powder out of the auger housing. The powder hose directs the carrier gas and carried powder from the auger housing to a powder dispenser.

A powder feeding device, in particular for coating powder, is disclosed. The powder feeding device includes a dense phase powder pump which has at least one conveying chamber with a powder inlet valve and a powder outlet valve. Furthermore, a control device is provided for selectively operating the dense phase powder pump in a powder conveying more or a flushing operating mode. The powder inlet valve and the powder outlet valve of the dense phase powder pump are configured in each case as a pneumatically actuable compression valve which can be closed when an actuating pressure is applied. The control device is configured to set the pressure value of the actuating pressure which is selected for closing the powder inlet valve and/or powder outlet valve depending on the respective operating mode of the dense phase powder pump and/or depending on a pressure which prevails in the conveying chamber.

An air cart for distributing air entrained particulate material from a chamber or tank to a plurality of distribution lines for application to an agricultural field has a tank refilling feature utilizing air flow from the cart distribution system or from a dedicated pneumatic source. The cart conveying system air flow is diverted and passed through an assembly containing multiple venturis which also receives particulate material from a supply source. The air entrained material from the source is conveyed to and gently deposited in the cart tank. Exhaust air from the tank may be directed back into the cart conveying system or vented through an air diffuser located beneath the cart. Exhaust air which is directed back to the cart conveying system may return to a location closely adjacent that from which it was originally diverted.

The present disclosure includes an agricultural system having first and second product meters configured to meter product to first and second lines, respectively. First and second motors are coupled to the first and second product meters and configured to drive them at first and second metering rates, respectively. An air source is configured to provide first and second airflows to the first and second lines, respectively. A controller electrically coupled to the first and second motors is configured to receive first and second inputs indicative of first and second numbers of first and second outlets fluidly coupled to the first and second lines, respectively. The controller is configured to instruct the first and second motors to drive the first and second product meters at the first and second metering rates, respectively, based on the first and second inputs, and to instruct the air source to provide the first and second airflows with first and second dynamic pressures or first and second velocities.

A vacuum nozzle includes a main body and at least one auxiliary body. The main body has a first open end and a second open end. The first open end is coupleable to a vacuum hose and the second open end is configured for receiving materials to be transferred. The auxiliary body has a first auxiliary opening and a second auxiliary opening. The first auxiliary opening is positioned closer to the first open end of the main body than the second open end of the main body. The second auxiliary opening covers a portion of the second open end of the main body. The auxiliary body provides a dedicated auxiliary passageway for providing a consistent flow of air to the second open end of the main body when the vacuum nozzle is in use.
