A proppant delivery assembly receives and supports a plurality of containers having proppant stored therein. A cradle has a top surface which receives and supports the plurality of containers when positioned thereon. The cradle enables the plurality of containers to dispense the proppant stored therein. A proppant mover is positioned to underlie and extend along the top surface of the cradle aligned with the plurality of containers to receive proppant from the plurality of containers. The proppant mover carries proppant away from the plurality of containers. A chute is coupled to the cradle for receiving proppant from the proppant mover and directing the proppant to a blender hopper. A hood assembly is disposed at an end of the chute opposite the proppant mover for directing a vacuum air flow that removes a volume of air containing proppant dust particles directed from the chute. The hood assembly includes a curtain extending about a perimeter of the hood assembly and downward therefrom to at least partially define the volume of air being removed by the hood assembly.

A loading apparatus for a granular material conveyor system having a conveyor belt is described. The apparatus has a chute assembly mounted to a frame over the conveyor belt and having an adjustment mechanism and a positional lock assembly connected to the chute assembly and the frame for adjusting an upper surface of the chute assembly to a desired angle within a range of possible angles. One or more side deflector panels are mounted to the frame over the conveyor belt and an adjusting rod assembly connects the deflector panels to the frame for adjusting an angle of the deflector panels.

A transfer or distribution chute for conveying bulk material by gravity flow includes an elongated chute casing defining a flow path for bulk material and a wear-resistant lining arrangement covering at least part of a flow path facing an upper side of the elongated chute casing. The wear-resistant lining arrangement includes a perforated plate affixed to the chute casing and has a plurality of perforations through which wear-resistant inserts having a body and an enlarged base are fitted in the perforations from a side opposite the flow path, such that their body protrudes through the perforation within the flow path, and their enlarged base abuts the borders of the perforation from the side opposite the flow path on one side and is held in place by the chute casing on the other side.

The present subject matter relates to systems and methods for automatically determining the level of an open chute door in connection with a chute system in a building structure. The position of the open door on the chute is automatically determined, without requiring any configuration at each door on the chute, utilizing a daisy chain wire signal connection and a chute busy wire (enable signal) signal connection. Pulses or other signals are counted at a base station to determine the level of the open door.

A chip chute system structured and/or configured to capture chips cut from a stump by a stump grinding/cutting wheel, harness the energy in the cut chip imparted by the stump grinding wheel, and control/direct the cut chips to a desired chip collection location such as a bin or other collection receptacle.

A system is disclosed for conveying proppant from a container to fracking operation equipment. The system includes a proppant delivery assembly having a frame supporting the container adjacent a proppant mover having a conveyor, a shroud enclosing a portion of the conveyor, a proppant chamber coupled to the shroud and a chute coupled to the proppant chamber. The system also includes a dust collection assembly fluidly coupled to the proppant mover to collect the dust particles contained therein. The dust collection assembly includes an air mover, a hood with a dust receptacle, and ductwork coupling the air mover to the dust receptacle. An air flow is generated along a flow path through the dust receptacle and the ductwork to the air mover such that a suction pressure generated by the air mover is sufficient to only capture and remove the dust particles, thus reducing a risk of capturing the proppant.
