Definitions

  • the present invention refers to devices to be mounted on a motor vehicle for cleaning roadways, in particular solid refuse which must be pushed towards collection points.
  • devices generally comprising a blade are used, which are mounted so that their lower edge moves substantially at ground level.
  • the blade comprises a central element equipped with means for mounting on the vehicle, and a pair of lateral elements, which are pivotally connected to the ends of the central element along substantially vertical axes, and which can be swiveled by means of hydraulic or pneumatic actuators. In this way, parts of the roadway of different widths can be cleaned.
  • pavements have, in section, a certain convexity, greater towards the edges, and known blade devices, the height of which on the ground is constant, involve the risk that part of the material to be removed passes under the lower edge of the blade without being collected.
  • the device according to the invention which is characterized in that the articulation pins of the lateral elements are carried by lever members pivotally connected to the central element along respective substantially horizontal axes, so as to allow pivoting of the lateral elements in a substantially vertical plane, and in that the lever members are connected to means loaded by a spring to adjust the force exerted by the side elements on the ground when they are inclined relative to the central element.
  • the device comprises a central blade element 1 and two lateral elements 2, 3 which can pivot, relative to the central element, both around a vertical axis and a horizontal axis .
  • the device can be adapted both to different widths of the area to be cleaned and to the possible lack of evenness of the roadway.
  • the device can be mounted on the front part of a motor vehicle by means (not shown) carried by the central element 1. These means are conventional. Conventional hydraulic or pneumatic devices, also not shown, allow the lateral elements to pivot about the vertical axis.
  • the elements of the device are made of metal sheet, for example steel, and have an upper part 1a, 2a, 3a in grid. In the lower part they are provided, as usual for these devices, with appendages 5 of a material having a certain degree of flexibility, for example rubber, which allow the device to overcome fixed obstacles of limited height (for example example pavement irregularities) during cleaning operations, always keeping substantial contact with the pavement.
  • a material having a certain degree of flexibility for example rubber
  • each lateral element At the end of each lateral element opposite the central element there is a fin 6, also made of a material having a certain flexibility such as rubber.
  • the fin is pivotally mounted on a vertical axis on the lateral element and can rotate relative to the latter, thus making it possible to exceed fixed lateral obstacles.
  • the assembly of a fin is shown in more detail in Figure 3.
  • the vertical hinge pin between a lateral element (such as element 2) and the central element 1 is indicated by 7 and by 8, 9 the seats for this pin, made respectively in element 1 and in element 2.
  • the seats 8 are produced in a lever member 10 parallel to the pin 7 and connected lower to the element 1 so as to pivot around a horizontal axis, perpendicular to the plane of element 1.
  • the pin 11 which passes through the lower part of element 1 constitutes this axis.
  • the lever member 10 is connected, using a pin 12 parallel to the pin 11, to the end part of a horizontal rod 13 which can move, against the action of 'a spring 15, in a sleeve 14 housed in a seat 19 produced in the upper part of the element 1 (under the grid 1a) and fixed to the element for example by means of a plate 20 pivotally mounted on the element using a pin 33.
  • the sleeve 14 also houses the spring 15.
  • the spring 15 bears against a piston 16 which can be moved in the sleeve 14 using a screw 17, to vary the degree of compression of the spring 15 and adjust the force exerted towards the ground by the side element.
  • the screw 17 passes through the piston 17 and engages with the rod 13. Its head 17a forms a button for manual adjustment.
  • a stud 18 which can be removed makes it possible to make the rod 13 and the member 10 integral with the element 1 when it is desired to work with the element 2 horizontal. Its removal allows that, by effect of the weight of the side element 2 or the compression of the spring 15, the lever member 10 rotates around the pin 11 causing the displacement of the rod 13 in the sleeve 14, this displacement being limited by button 17a.
  • the degree of preload of the spring 15 will be established according to the nature of the material to be collected, so that the resistance opposed by the latter does not cause the pivoting of the lateral element upwards around the pin 11.
  • An irregularity of the ground or a variation of the inclination thereof may on the contrary cause this pivoting until bringing the button 17a against the goal of the seat 19, thereby causing the compression of the spring 15; once the fixed obstacle has been passed, the element will again gain the original inclined position.
  • the figure also shows an appendage 32, integral with the member 10, which engages in the central element 1 to ensure better support for the lateral element.
  • Figure 3 shows that a spring device similar to that just described connects the support 21 of the fin 6 to the side element. More particularly, a rod 25 comprising an axial recess forming the seat for a spring 26 is pivotally mounted, along an axis 23 parallel to the pivot axis of the fin (pin 24), on a stirrup 22 fixed to the support 21.
  • the rod 25 is housed, for part of its length, in a sleeve 27 carried by a stirrup 28 secured to the lateral element (element 2 in the drawing) of the device.
  • the sleeve 27 houses a spring 26, which can be preloaded by a screw 30 engaging in a nut 31 carried by the sleeve 27.
  • the fin 6 will keep its normal position (in the same plane of the element 2) until it strikes against a fixed obstacle capable of overcoming the resistance of the spring 26; under these conditions the fin will pivot around the pin 24 and will cause the sliding of the rod 25 and the compression of the spring 26. Once passed the obstacle, the spring will bring the fin back to the normal position.
