Benefits of technology

The objective of this patent is to create a simple and affordable spread unit that solves issues in a more efficient manner.

Problems solved by technology

The known units of the above-described type are not very satisfactory, especially concerning the distribution uniformity of the anti-icing material.
Moreover, in both cases, many of the parts forming the conveyors wear out in relatively short time.

Embodiment Construction

[0011]In the accompanying figure, numeral 1 indicates a spread unit for spreading granular material as a whole, such as for example an anti-icing saline substance, on an extended surface 2 such as e.g. a paving in general, a street surface, a parking lot, a harbour or airport area, etc.

[0012]The unit comprises a frame 3 adapted to be connected, for example to a self-propelled unit 4 (partially shown), and a container 5 for the granular material and supported by frame 3.

[0013]Container 5 comprises a front frontal wall 6, a rear frontal wall 7 and two side walls 8 (only one of which is seen in the accompanying drawing), which converge towards each other and downwards to define, with the frontal walls 6, 7, an outlet 9 which is elongated in a longitudinal direction A.

[0014]Again with reference to the accompanying FIG. 1, unit also comprises a disk spreader 10, in itself known and not described in detail, for distributing the granular material over the above-mentioned extended surface 2...

Abstract

In a spread unit, a granular material, preferably anti-icing, arranged inside a hopper container, is fed towards a spread device by a feed assembly with a fixed support surface arranged in a position facing an outlet of the container and a belt dosing device arranged downstream of the fixed surface and on the outlet side for receiving the material from the fixed surface and dosing it before sending it to the spread device.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application is the national stage application of International Patent Application No. PCT / IB2012 / 055699, filed Oct. 18, 2012, entitled “Spread Unit for Spreading Granular Material”, which claims the benefit of Italian Application No. TO2011A000937, filed Oct. 18, 2011, both of which are hereby incorporated by reference herein in their entireties.TECHNICAL FIELD[0002]The present invention relates to a spread unit for spreading granular material. In particular, the present invention relates to a spread unit for spreading anti-icing granular material to be distributed on extended surfaces such as, e.g., pavings in general, street surfaces, parking lots, harbour and airport areas, to which the following disclosure will explicitly refer without however being less general.BACKGROUND ART[0003]The use of spread units is known for spreading anti-icing granular material, each comprising a hopper container accommodating a mass of such material ...
