Definitions

  • the present invention relates to a spread unit for spreading granular material.
  • 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.
  • spread units for spreading anti-icing granular material, each comprising a hopper container accommodating a mass of such material and having a lower opening, a spread device and a feed conveyor adapted to receive the material flowing out from said opening and to move it towards the spread device.
  • the object of the present invention is to make a spread unit, which allows the above-mentioned problems to be solved in a simple and cost-effective manner.
  • a spread unit is made for spreading granular material as claimed in claim 1 .
  • 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.
  • 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 .
  • 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.
  • 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 , and a conveyor and dosing assembly 11 for feeding the material in the longitudinal direction A and generating a homogeneous and continuous flow of material towards spreader 10 .
  • a disk spreader 10 in itself known and not described in detail, for distributing the granular material over the above-mentioned extended surface 2
  • a conveyor and dosing assembly 11 for feeding the material in the longitudinal direction A and generating a homogeneous and continuous flow of material towards spreader 10 .
  • the conveyor and dosing assembly 11 comprises a blade conveyor 12 , which extends in a facing position and basically for the entire length of opening 9 , for supporting—without deforming it—the material housed in container 5 and gradually flowing out from opening 9 , and a belt dosing device 13 arranged downstream of conveyor 12 in the material feed direction A and on the side of opening 9 , for receiving the material from the blade conveyor 12 and sending it to spreader 10 .
  • the blade conveyor 12 comprises a flat rigid wall 14 facing opening 9 and stably connected to frame 3 so as to close opening 9 , and a blade catenary 15 for translating the granular material deposited on wall 14 in the longitudinal direction A.
  • Catenary 15 comprises two drag chains 16 , which are transversally distanced from each other and are wound ringwise on end roller deviating bodies 16 , 18 having respective toothed mesh pulleys of the respective drag chains 16 .
  • the pulleys are keyed onto end sections of respective shafts 16 a, 18 a, which are arranged at longitudinal parts opposite to wall 14 and rotatably about respective axes 16 b and 18 b, which are parallel to each other and to wall 14 and are orthogonal to direction A.
  • shaft 16 a is motorised and is arranged downstream of the frontal wall 7 in an inlet 10 a of spreader 10 .
  • Catenary 15 further comprises a plurality of blades 19 , which are orthogonal and integrally connected to the chains 16 to slidingly cooperate with the upper surface 14 a of wall 14 and feed the material past the frontal wall 7 through an opening or passageway 20 obtained in the frontal wall 7 .
  • the dosing device 13 comprises a flexible belt 21 , which is conveniently made of polymeric or other similar material, which is wound ringwise about a longitudinal pair of end deviating rollers 23 and 24 , which are parallel to each other and to the axes 16 b, 18 b of the shafts 16 , 18 .
  • rollers 23 and 24 roller 23 is keyed onto the intermediate section of shaft 16 a between the related toothed pulleys, while roller 24 is arranged below and substantially at the frontal wall 7 or at passageway 20 .
  • the rollers 23 and 24 divide belt 21 into a delivery branch 21 a and a return branch 21 b; the delivery branch 21 a is substantially coplanar to the upper surface 14 a of wall 14 , to which it is conveniently joined by a plate portion 26 , and is arranged tangent to blade 19 to define, with the blades 19 , some pockets 27 housing predefined masses of material.
  • catenary 15 is not coupled to shaft 16 a but is wound about a motorised return shaft of it, again parallel to shaft 18 and arranged upstream of roller and independent from roller 24 . Therefore, catenary 15 and belt 21 of the dosing device 13 may be controlled independently from each other, so as to feed the material at different speeds in direction A, depending on the position of the material.
  • the dosing device 13 also comprises a crushing assembly 29 arranged in a position facing the delivery branch 21 a of belt 21 , for crushing the material being fed in conjunction with belt 21 and arranged between the blades 19 .
  • the weight supported by the dosing device 13 does not vary as the quantity of material housed in container 5 varies, thus the material is always fed under the same load or stress conditions and this, associated with the lack of related motion with catenary 15 , makes it possible to feed a constant flow of material.
  • the blade conveyor or the dosing device 13 of which belt 21 may be made with materials other than the one described, may be constructionally different from the ones described by way of example.
  • Spreader 10 may also be different from the one described.
