Description
A CONTROL DEVICE FOR A SPREADER
FIELD OF THE INVENTION
The present invention relates to a spreader device for spreading material on roadways, airport runways and the like such as a spreader device used for the snow and ice control industry. More specifically, the present invention relates to a control device for a spreader for surface conditioning of roads and highways by spreading materials for controlling snow and ice. Importantly, the control device for the spreader of the present invention is adapted to facilitate the spreader functions and is lo provided with user friendly features for ready visual indication of control parameters and related information input and generation.
BACKGROUND INFORMATION
It is well known to spread salt and sand to maintain a road during winter months especially to remove snow and ice from the road and to clear airport runways.
For such purposes it is also known to use a variety of spreaders which are attached to a conventional vehicle and which are used to spread the salt and sand and the like on the road. While there are many types of such spreaders, typically there are spreader mounting assemblies, which are used in conjunction with dump trucks and wherein the spreader is fastened adjacent to the tail gate of the truck.
Such spreaders are commonly used to convey materials such as salt, chemicals and f or sand for the purpose of spreading these materials onto the road surface thereby improving the road conditions.
In the use of spreaders for the snow and ice control industry, the spreaders usually include a spinner which is adapted to create a wide spray pattern behind the vehicle carrying the spreader in the process of spreading the conveyed material. Also depending upon the surface condition to be treated, the conveyed materials in case of the use of the spreader for the snow and ice industry thus include anti-ice agents and also preferably pre-wet agents.
Also for such surface conditioning or treatment, vehicles carrying spreaders can be used for a variety of purposes and are known to include snow plows, blowers and material spreaders alone or in combination. Importantly, the variety of applications require spreading of more than one material simultaneously in either a synchronous or asynchronous manner in either a predetermined ratio or in random proportions to a surface.
Moreover, the spreader may be required to apply material to a surface that can be all liquid, all solids or a combination thereof: In particular, in case of pre-wetting arrangements, both liquid and granular materials must be dispersed through a common device such as a spinner disk. The content of the granular material is usually higher with respect to the quantity of the liquid. Importantly, the material characteristics such as the granularity, density, viscosity and flow ability determine whether a separate or a common delivery system for such materials must be provided.
Spreaders used for spreading materials on roadways and airport runways for the control of ice and snow thus often involve both granular and liquid material to be spread simultaneously and the operator must set the spread width of the granular material and also the liquid material according to the width of the road to be covered.
In particular, in case of a change in the width of the road and also depending on the ice and snow to be cleared, the operator is required to monitor and adjust the spread width and other spread parameters to suit the desired end application.
Accordingly, those skilled in the art will appreciate that spreaders and their function and operation essentially require continuous and constant monitoring of the various control parameter and the input of necessary instructions to activate the spreader for spreading the material at desired levels to achieve the optimum results.
Accordingly, the present invention provides a control device for a spreader for spreading material on a road and the like such as those required for the snow and ice control industry, which employs user friendly controls and activation of the spreader system.
More specifically, the present invention relates to a control device for a spreader for spreading material on a road which includes a visually appealing multi color display of control parameters.
The present invention also provides a control device for a spreader for spreading material on a road which is user friendly during operation and which does not require the typically used keyboard or mouse to input instructions for operation of the spreader.
In particular, according to the present invention, the control device for a spreader for spreading material on a road finds particular application in spreader units requiring monitoring of control parameter and activating the spreader functions according to the required end use or purpose.
Therefore, it is a primary feature of the present invention to provide a control device for a spreader used for spreading material on a road which overcomes the complexities of monitoring control parameters and / or carrying out typical functions of a spreader device which uses a conventional key board and mouse for the input of instructions for effectively operating the device.
Another feature of the present invention is to provide a visually appealing multiple color display of control parameters representing certain functions or a level of warnings in a spreader system.
A further feature of the present invention is to provide a user friendly operation and use of a spreader system involving a touch screen which would enable the user to use the user's finger or a type of stylus to press against the display area and enter information into the system.
A further feature of the present invention is directed to improve the design feature and aesthetic appearance of a spreader device and in the process make it simple and user friendly to the end user or operator.
Other features and advantages of the present invention will be readily apparent to those skilled in the art by a consideration of the detailed description of a preferred embodiment of the present invention contained herein.
