1. Field of the Invention
This invention relates to a road salt spreader for driving along a road, and that the granular salt particles can with this device be spreaded in a zone extending on each side of the central line until the zone destined for circulating.
2. Description of the Related Art
A search of prior art records has unveiled the following patents:
It is a perpetually recurrent problem that the friction of the roadway surfaces is reduced substantially by ice and snow when the temperature falls below freezing point. Thereby, the roads become slippery and dangerous to drive on to the wheeled traffic.
In the past, numerous types of salt spreaders have been developed to be attached to the conventional vehicles. Typically, the spreader is mounted on the rear of the vehicle to spread particulate material, such as salt, sand, etc. onto the surface being traveled by the vehicle.
A method to reduce the risk of traffic accidents on icy roads consists in a spreader assembly that is adapted to be mounted to the chassis of a vehicle. The spreader assembly is utilized for the specific purpose of depositing granular salt particles upon roadways.
The novel and unique features according to the invention, whereby this is achieved, is the fact that the spreader assembly includes two chutes that are retained to the chassis of the vehicle by the chains and connected to a trap that is pivotally mounted therefrom.
The trap is actuated by a hydraulic cylinder designed to close inwards or outwards for sending granular salt particles via a chute to be directed toward a spreader disc that rotate by a motor-driven shaft for spreading over iced or snowed zone extending on each side of the central line until the zone destined for circulating.
When the salt spreader is operating and that the vehicle operator closes the trap outwards the granular salt particles are oriented inwards via a chute to be directed toward the spreader disc that rotate for spreading over iced or snowed zone extending on each side of the central line.
And when the salt spreader is operating and that the vehicle operator closes the trap inwards the granular salt particles are oriented outwards via a chute to be directed toward the spreader disc that rotate for spreading over iced or snowed zone extending until the zone destined for circulating.
Referring now to the drawings, wherein the showings are for the purpose of illustrating the preferred embodiment of the invention only and not for the purpose of limiting the same, in
In the shown case, the spreader assembly is adapted to be mounted to the chassis (B) of the vehicle (C).
The spreader assembly includes two chutes (11)(25) that are retained to the chassis (B) of the vehicle (C) by the chains (37)(38) and connected to a trap (1) that is pivotally mounted therefrom.
The trap (1) is actuated by a hydraulic cylinder (34) designed to close inwards or outwards for sending granular salt particles via a chute to be directed toward a spreader disc (39) that is assembled to the chassis (B) of the vehicle (C) and that rotate by a motor-driven shaft (41) for spreading over iced or snowed zone extending on each side of the central line until the zone destined for circulating.
