A self-driven modular sandbagging device applicable to a dump-truck with a truck bed that defines a sand carrying volume, comprising: a replacing tailgate for the truck bed, capable of replacing the original regular tailgate of the dump-truck, at the lower inner end of the replacing tailgate an integral elongated housing is included, in free contact with the carrying volume of the truck bed, in the integral elongated housing an auger is rotatably installed; the auger is driven by a hydraulic motor located inside the housing, a hydraulic pump connected to the hydraulic motor is attached to the external side of the replacing tailgate, at one end of the housing a bag-filler nozzle is included.

A telescoping rotatable tool includes a first shaft and a second shaft. The first shaft has a first material-engaging element extending from an exterior surface of the first shaft. The second shaft has a second material-engaging element extending from an exterior surface of the second shaft. The second shaft is configured to extend from and retract within an interior space presented by the first shaft. The first shaft includes at least one helical-shaped groove extending along an interior surface of the first shaft. The second shaft includes at least one guide element extending from the exterior surface of the second shaft. The guide element is configured to engage with the groove, such that as the second shaft extends from and retracts within the first shaft, the second shaft is configured to rotate with respect to the first shaft.

An exemplary embodiment of the present invention is directed to an apparatus for emptying material from a container on a vehicle. The apparatus has a container with a bottom surface and a sidewall. A membrane being mounted within the container proximate the sidewall and the bottom surface. The apparatus further includes an engine and ducts having a first end and a second end. The first end connected to the engine so as to receive gas from the engine and connected at the second end to the membrane so as to direct the gas into the membrane.

A farm implement includes a frame, a container mounted on the frame, an intake housing rotatably connected to a front wall of the container proximate to a discharge opening, a first auger assembly, and a second auger assembly. The first auger assembly is disposed in the container and conveys agricultural material through the discharge opening. The second auger assembly is rotatably connected to an outlet of the intake housing and includes an inlet that receives agricultural material from the intake housing and an outlet that discharges agricultural material. The farm implement further includes a first mounting assembly and a second mounting assembly disposed along the front wall. The second auger assembly is mounted on one of the first and second mounting assemblies at an operating position, without being mounted to the other one of the first and second mounting assemblies.

A cement silo and feed apparatus for feeding cement to the cement silo of a mining machine includes a receptacle for receiving cement, a transfer tube connected at a first end of the receptacle for guiding the cement from the receptacle to the cement silo connectable at a second end of the transfer tube and transfer means arranged in connection with the transfer tube and arranged to move cement within the transfer tube from the receptacle to the cement silo. The transfer tube includes at least one transfer tube section having a tube-like inner space for cement to be transferred.

A conveyor support system has a primary arm and a secondary arm. The secondary arm has a generally vertical, rotatable shaft at its distal end. The vertical shaft supports pivoting of a conveyor system about the shaft. A powered wheel and tire assembly is mounted on the conveyor, under an intake end of the conveyor, and is oriented in a position to drive rotation of the conveyor about the vertical, rotatable shaft disposed at the distal end of the secondary arm. The primary arm is mounted to the agricultural machine and is configured to move the conveyor from its transport position to a position in which it can be rotated to its deployed position.

An asphalt receiving vehicle includes a receiving hopper that is adapted to receive a load of asphalt paving material from a supply truck, and a conveyor that is adapted to convey the asphalt paving material received from the supply truck out of the receiving hopper. A plurality of guidance lights are mounted on the asphalt receiving vehicle so as to illuminate the roadway adjacent to the receiving hopper to provide a landing pattern to assist a driver of the supply truck to properly maneuver the supply truck as the supply truck is backed into position adjacent the receiving hopper. In a preferred embodiment of the invention, the plurality of guidance lights may also be used individually as directional signals.

A control assembly provides autonomous control of various functions of a grain cart and/or provides guidance to an operator of the grain cart during the unloading of a grain cart. The control assembly collects input from one or more sensors including a speed sensor to monitor speed of a PTO that drives the unloading auger of the grain cart, a height sensor that measures the height of material discharged from the grain cart into a receptacle such as a grain truck, and/or a boundary sensors that measure lateral position of the grain cart relative to the receptacle or grain truck. Based on the input, the control assembly may vary the position of the discharge gate of the grain cart, or provide guidance to the operator to steer and position the grain cart relative to an adjacent grain truck.
