Abstract:
An automatic treatment material spreader device that is designed to automatically spread a treating material such as a salt or fertilizer for treating lawns, gardens, driveways, and parking lots. The device includes a rectangular body having a truck bed for storing treatment material, tank treads for mobility, and a funnel with rotating blades for metering and spreading the treatment material to a target area. The device is remotely controlled by an operator through a software application wherein the device can run on electrical supply provided through an internal battery. The internal batter can be charged by a wireless charging dock. The device can be programmed through the software application to spread the treatment material within a specified area and a specified treatment schedule. The device provides real time information about its location, material volume, and battery status.
Abstract:
A method for calculating the change in mass over time of a storage area holding a load, while components of the load are being removed or added, and while the storage area is subjected to changing vertical acceleration, is disclosed. The method uses a computer to compare the measured weight of a load with a known mass to the measured weight of the variable load and calculated the mass of the variable load. Periodic measurements and calculations allow the change of the variable load over time to be determined. Controls influencing the addition and removal of load components maybe controlled in response to the calculated change in mass to maintain targeted rates of change.
Abstract:
An apparatus for broadcasting particulate or granular material over a ground surface involves a variable speed spinner and a material conveyor. The spinner is positioned generally horizontally below a discharge end of a material conveyor. The spinner has a disk having a generally radially disposed fin fixed to an upper side of the disk and radiating outwardly from a center of the disk. The spinner is positioned to receive material from the material conveyor at a location about half way along a length of the fin. In a method broadcasting particulate or granular material over a ground surface, the spinner is preferably rotated at a speed of 900-1000 rpm. The apparatus and method provide for distribution of material over greater distances and can do so without pulverizing the material, creating a uniform pattern of distribution over a 50% wider swath.
Abstract:
A civil engineering machine for spreading material for spreading on soils or base materials, and in particular a civil engineering machine for spreading binders for soil or base material stabilization, has a container for material for spreading to receive the material for spreading and a spreading arrangement having one or more outlet openings for the discharge of the material for spreading. An anti-dust arrangement is arranged below the outlet openings, and is characterized in that there is created below the outlet openings a spreading compartment which is bounded by one or more first anti-dust members and in that there is created an anti-dust space which is bounded by one or more second anti-dust members.
Abstract:
A bin for a sand spreading vehicle is provided with curved lower sidewalls that deliver sand to a central conveyor. The curvature of the sidewalls lowers the center of gravity of the vehicle for a given load; or permits carriage of a greater load for a given height for the center of gravity of the loaded bin.
Abstract:
The present invention is a control system for a vehicle that utilizes a powered attachment such as a material spreader. Such a device requires the use of a high current drawing motor, which in turn requires the ability to control the flow of high amperage current. The high current switching circuitry is mounted on or near the electric motor to prevent the heat generated by the circuitry from posing any type of hazard. A low current control is placed within the cab of the vehicle and serves to remotely control the switching circuitry.
Abstract:
A clutch mechanism (88) for a ground-driven top dresser (10) is actuated by an electric actuator (139) pivotally mounted to a U-shaped bracket (104). The shaft (141) of the actuator (139) is connected to flanges (135) radially extending from a rotatable tube (132) through a lost motion means in the form of elongated slots (145) formed in the flanges (135) and which slideably receive a pin (143) carried by the actuator shaft (141). A cam (134) is removably attached to flanges (133) radially extending from the rotatable tube (132) opposite to the actuator flanges (135). The cam (134) has first and second portions (136a,b) for engaging the pivotal arm (110) which engages and disengages the clutch mechanism (88). The spring (96) biasing the jaw members (90, 92) of the clutch mechanism (88) together allows the cam (134) to circumvent the constant velocity extension of the actuator (139) due to the lost motion connection to quickly engage the clutch mechanism (88) when the cam (134) moves to an over-center position from the second portion (136b) to the first portion (136a) of the cam (134).
Abstract:
In accordance with an example embodiment, a method of operating a work vehicle with an ejector body may include receiving a position signal indicative of a position of the work vehicle, receiving a target profile indicative of a target topography for an area, receiving an ejection command at a controller and entering the controller into an ejection mode based on the ejection command, and controlling, with the controller, in the ejection mode, at least one of a speed of the work vehicle and a speed of an ejector included in the ejector body based on the position signal and the target profile, to spread a load of material from the ejector body onto a ground surface.
Abstract:
A system and method for the application of friction-modifying coatings to roadways, walkways, pathways and other areas subject to vehicular, human or animal traffic, the system and method comprising the controlled, simultaneous application of binder and filler to a surface of a substrate, using a mobile device which passes over the substrate as the binder and filler are being applied. The system includes a frame coupled to a vehicle. A spray bar is mounted on the frame and includes an array of spray nozzles coupled to a resin container. An air knife is mounted on the frame and coupled to an air compressor for generating an air curtain. An aggregate dispenser bar including at least one aggregate dispenser is coupled to an aggregate bin and mounted on the frame for dispensing aggregate.
