A dry-bulk tanker for the provision of binding agent for soil stabilization for a spreading device, comprising a storage container (10) for binding agent. An intermediate chamber (20) is connected to the storage container and is also connected to a compression chamber (40). A conveying device (22) for conveying of binding agent into the compression chamber (40) is arranged in the intermediate chamber (20). A conveying channel (44) is connected to the compression chamber (40). The conveying channel (44) can be connected to a spreading device (58). Furthermore, a pneumatic line (46) for feeding of conveying compressed air is connected to the compression chamber (40) and/or the conveying channel (44).

A reconfigurable modular hopper spreader assembly is mountable in the bed of a truck and includes a modular dual-wall hopper with a receptacle for storing solid material to be spread onto the ground and with individual liquid chambers for storing a liquid or different liquids to be sprayed onto the ground. The hopper spreader assembly further includes a fluid conduit for filling or draining the liquid into or out of the liquid chambers, a liquid pump fluidly connected with the liquid chambers for drawing the liquid from the liquid chambers, a selector valve fluidly connected with the fluid pump for directing the liquid drawn from the liquid chambers, and a liquid dispenser fluidly connected with the selector valve for distributing the liquid onto an application area.

A material spreader is mountable to a rearwardly projecting bumper of a vehicle for conveying and spreading material, the vehicle including a rearwardly projecting hitch receiver. The material spreader includes a hopper for holding material to be spread, a frame supporting the hopper and having a forwardly projecting hitch mount configured for coupling to the rearwardly projecting hitch receiver of the vehicle, and a support member having an underside for resting atop a top surface of the bumper, the support member being movable vertically relative to the frame. A tie down is connected to the support member and the frame for urging the support member and the hitch mount towards one another to effect a clamping action on the receiver and the bumper. The material spreader also includes a dual hinged lid and a gear box for driving a spinner and an auger.

The systems can include any suitable component that allows them to move material (e.g., gravel and/or another bulk material), under at least a portion of a frame or other portion of a vehicle, and from one portion of the vehicle to another portion. In some cases, the systems include a chip spreader that includes a motorized vehicle and a material transfer device that is configured to move the material from a first end of the motorized vehicle to a second end of the motorized vehicle. In some cases, the material transfer device is disposed below an axle, frame, drivetrain, radiator, and/or other component of an undercarriage of the motorized vehicle. In some cases, the material transfer device includes one or more conveyors, augers, vibrators, gravity slides, and/or pneumatic systems that are configured to move the material.

A spreader assembly may include a hopper, a pair of augers positioned in a dual auger arrangement and a metering gate assembly including a gate and a biasing force generator. The gate may have a general M-shape with an inner extension and may be positioned generally above the augers with the inner extension extending between the augers. The biasing force generator may be operable to apply a biasing force to the gate causing the gate to operate as a metering gate.

Other implementations are described.

A salt spreader for distributing a material includes a bucket including a front surface, a rear surface, first and second side surfaces, and a base surface, wherein the front and rear surfaces tend toward one another, and wherein the base surface includes an ejection port, a spinner mount attached to the base surface of the bucket under the ejection port, a spinner rotatably mounted atop of the spinner mount, and an auger positioned in a base of the bucket.

A method of controlling a DC motor that includes the step of providing a pulse-width modulation (PWM) signal to the DC motor. The PWM signal provides a voltage to operate the DC motor. The method also includes the steps of measuring a voltage generated by the DC motor when the PWM signal is off. In more particular embodiments, the method includes measuring a current being supplied to the DC motor when the PWM signal is off. The method may further require determining a motor speed of the DC motor based on the measured voltage. The method further includes controlling the DC motor to maintain a relatively constant motor speed with varying loads on the DC motor.

An auger segment can comprise a base having a first end, a second end opposite the first end in a length direction of the base, a first side, and a second side opposite the first side; a first receptacle projecting from the first side of the base; a second receptacle projecting from the first side of the base; and a flight projecting from the first side of the base between the first receptacle and the second receptacle. A first recess of the first receptacle can be defined by a first sidewall thereof and a second recess of the second receptacle can be defined by a second sidewall thereof. A first through hole can extend through the base in the first recess of the first receptacle and a second through hole can extend through the base in the second recess of the second receptacle.
