  • Patent number: 11661291
    Abstract: A support apparatus includes a frame assembly with an elevated load surface for supporting a modular proppant container in a position above a ground level. A chute assembly is supported by the frame assembly beneath the elevated load surface. A gate actuator has a coupling configured to engage with a gate assembly of the modular proppant container supported on the elevated load surface and a drive mechanism extending between the frame assembly and the coupling to selectively position the coupling for adjusting the gate assembly. The support apparatus may include a base frame section having a recessed region beneath the elevated load surface providing a feed station, an on-board subsystem attached to the frame assembly for operating the support apparatus in a stand-alone mode or an in-situ weigh station configured to measure the weight of the modular proppant container supported on an elevated surface in the rectangular container bay.

  • Patent number: 11649122
    Abstract: A grain spreader apparatus is powered in rotation by the flow of grain through the grain spreader apparatus. The gravity grain spreader includes a distribution hopper mounted at the top of a grain storage bin to receive a supply of grain to be distributed within the grain storage bin in a uniform manner. The distribution hopper delivers the grain into a pair of opposingly oriented chutes meeting at an apex underneath the distribution hopper. Each chute is provided with a terminal deflector at the end of the chute, and with intermediate deflectors built into the sides of the chutes to provide a more uniform dispersal of the grain into the grain storage bin. The angle of repose of the chutes is variable through an adjustment mechanism so that higher moisture grains can be fed through the grains spreader apparatus and effectively distributed.

  • Patent number: 10131458
    Abstract: The Adjustable Chute is a user friendly product for consumers to dispose of lawn debris and or grass clippings collected from a grass catcher from a lawn mower. The Adjustable Chute is constructed of durable materials for longevity and reliability purposes. The unique design of the Adjustable Chute with the upper portion rectangular for easy attachment of the grass catchers itself, and lower portion tapered for easy disposal of yard waste or grass clippings, allows hands free transfer of yard waste from a grass catcher through the Adjustable Chute into the waiting collection brown bag. The Adjustable was conceived through personal necessity after realizing how incredibly difficult it is to transfer grass clippings after being collected in a grass catcher from the grass catcher into the brown recycle bag.

  • Patent number: 3976176
    Abstract: A spiral chute device, especially for use in conveying seed materials to storage chambers. The spiral chute device is employed for guiding the seed material downwardly in the storage chamber to prevent the seed material from undergoing free fall which could lead to cracking thereof. The device is, preferably, suspended from the top wall of the chamber and has a hopper at the top with an upwardly opening spiral chute extending downwardly therefrom to near the bottom of the chamber. The device includes a center post telescopically engaged by a guide member at the center of the bottom wall of the chamber and the device can be moved laterally in the chamber by disengaging the lower end of the post from the guide member.
