The particularity of this invention is that the material is injected in the divergent section of the venturi.

The innovative material Conveying Venturi tube consist of two parts: the main tube and the feeding tube injecting the material by gravity, at the end of the cylindrical throat into the diffusion section. The venturi is composed of a contraction section, a throat section, and a diffusion section.

This device will convey distances exceeding 120 meters. The present invention permits multiple distances conveying by easily install another Conveying Venturi System at the end of the first conveying tube for extra length of conveying.

A vacuum nozzle includes a main body (12) and at least one auxiliary body (22). The main body has a first open end (16) and a second open end (18). The first open end is coupleable to a vacuum hose (2) and the second open end is configured for receiving materials to be transferred. The auxiliary body (130) has a first auxiliary opening (136) and a second auxiliary opening (138). 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.

An agricultural product delivery applicator for delivering particulate product to a field. The applicator includes a bin having a first chamber to hold a first product, a second chamber to hold a second product, and a third chamber to hold a third product. The applicator further includes a pneumatic conveying system having an airflow source to provide an airflow, a delivery line operably connected to the airflow source and to the bin, and an outlet coupled to the delivery line. A metering system is operably connected between the supply compartment and the pneumatic conveying system. The metering system meters product with the airflow to result in a mixed flow of airflow and product. The metering system includes a novel hydraulic circuit for helping to meter the product.

A snow conveying assembly for use with a snow making machine includes an impeller for receiving snow from the snow making machine and accelerating the snow; and an ejector tube, which receives the snow from the impeller, further accelerates the snow and discharges the snow from the assembly. The ejector tube contains a venturi throat. Snow from the impeller is conveyed via a snow inlet tube into the ejector tube immediately upstream of a venturi throat and air under pressure is blown into the ejector tube upstream of the venturi throat to further accelerate the snow.
