SYSTEMS, DEVICES, AND METHODS FOR STORING AND SPREADING A MATERIAL
A material spreading system may include a tote and a spreader attachable to a loading machine. The spreader may include a frame, an inlet, a lift arm, and a discharge mechanism configured to selectively discharge the material onto the ground. The tote may include a container having a plurality of walls enclosing an internal volume for storing a material. An opening may be formed in one of the plurality of walls and communicate with the internal volume. The tote may additionally include a lift arm engaging surface configured to engage the lift arm and permit the lift arm to manipulate the tote. The tote may also include a closure member at least partially covering the opening and configured to selectively permit transfer of the material from the container to the inlet of the spreader in response to the material exerting a force on the closure member.
SPREADING VEHICLE WITH SLOPING SPREADING DISCS AND FILLER PIECE
A spreading vehicle, e.g. universal spreader, comprises at least two spreading discs by which spreading material is thrown. The spreading discs are mounted at the rear end of the spreading vehicle and, on the top side, comprise drivers by which spreading material is captured. The spreading discs rotate with a predetermined rotational speed about their axis of rotation, and are inclined relative to the horizontal, transversely to the travelling direction of the spreading vehicle, by a predetermined non-zero angle. Between the spreading discs, at least partially, a filler piece is arranged to feed spreading material to the spreading discs. The filler piece has a center axis and extends in the direction of the centre axis along a portion having a portion length between the spreading discs. The portion length is greater than a radius of the spreading discs and in cases smaller than twice the radius of the spreading discs.
Spreader with removable material transportation mechanism
A spreader assembly may include a hopper configured for receiving a spreadable material, a removable cartridge configured for sliding engagement with the hopper and having a material transportation mechanism configured for receiving the spreadable material from the hopper, and a spreader configured for receiving the spreadable material from the material transportation mechanism and spreading the spreadable material onto a target surface. One of the hopper and the cartridge may include a roller having a roller surface, and the other of the hopper and the cartridge may include a bearing surface configured for rolling engagement with the roller surface.
HOPPER SPREADER WITH BACK EMF CONTROL AND HOPPER SYSTEM SPEED CONTROL
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.
TRUCK-MOUNTED MATERIAL SPREADER
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.
SPREADER ASSEMBLY
A spreader assembly to distribute materials on a ground surface, including a container to hold the materials, a frame affixed to the container, a beater assembly supported by the frame that receives the materials from the container and processes the materials to obtain processed materials, and a spinner assembly that receives the processed materials and expulses the processed materials from the frame onto the ground surface. The beater assembly includes a pair of rotating elements that blends the materials to produce the processed materials, and a deflector located between the pair of rotating elements configured to prevent the formation of agglomerates in the processed materials.
System and method for mobile subvehicular access and treatment of ground surfaces about occupied rail tracks
A system and method are provided for subvehicularly accessed treatment of ground surfaces about a rail track occupied by a rail vehicle. A mobile treatment unit having a propulsion mechanism for subvehicular passage between the rails occupied by the rail vehicle includes a dispensing portion for expelling a treatment material therefrom onto regions of the ground surface about the rails. The mobile treatment unit is maneuverable between the rails and maintains height clearance for unobstructed passage beneath the occupying rail vehicle. At least one sensor unit is coupled to the mobile treatment unit, which acquires environmental feedback data about the mobile treatment unit. A control unit is operably linked to the mobile treatment and sensor units, and receives the environmental feedback data. The control unit controls actuation of the mobile treatment unit responsive to the environmental feedback and/or a maneuver control command.
BROADCAST SPREADER WITH SWATH MANIPULATION
A spreader with a material divider that is adjustable from side to side so as to change a percentage of a stream of material which flows through portions of the material divider and also supports and moves laterally with a spinner while the spinner is adjustable longitudinally. The geometry of spread patterns can be adjusted by laterally manipulating the location of the material divider.
Control cable system incorporating stabilizer guide
A push-pull cable system including a cable assembly, a stabilizing element, and a guide member. The stabilizing element and guide member may maintain alignment of a wire of the cable assembly as it pushes against a mechanism resistive force that is not aligned with the wire itself. As a result, the cable system may be utilized in applications wherein space constraints prevent alignment of the wire with the resistive force vector of the mechanism.
SPREADER ASSEMBLY
A spreader assembly for spreading sand or salt comprised of a molded, double-walled hopper having a bin portion and leg portions. The hopper has an inner wall and an outer wall, wherein the inner wall has a front end section and opposing side sections. The end sections and the side sections define a media-holding chamber within the bin portion of the hopper. The chamber has a generally rectangular upper portion, a funnel-shaped lower portion and a bottom having an opening extending through the bin portion. The funnel-shaped lower portion of the chamber slopes toward the opening. The outer wall of the hopper defines the leg portions, and the leg portions are dimensioned to extend below the opening in the bin portion.
