Definitions

  • the present invention relates to machines for cleaning sand, removing stones and other large foreign bodies therefrom and has as its main object to noticeably improve the efficiency of the known machines of this kind.
  • a further object of the invention is to cut down the bulk of such known machine when in its rest condition, such that it can be lodged in standard transportation con­tainers.
  • a known sand cleaning and stone removing machine comprises a ramp or blade located at its leading end, as regards the direction of motion of the working machine and which sinks itself into the sand and drives it towards the upper run of an endless inclined mesh or screen which is moved continuously in the opposite direction while it is subjected to a vibrating movement.
  • a revolving beating device formed of a plurality of radial arms or fingers is­suing from a revolving shaft, is located over the ramp and pushes the stones and large bodies picked up by the machine, towards the screen, this latter leading to a hop­per for collecting the stones and bodies larger than a given size as defined by the screen mesh.
  • the hopper is associated with a hopper dumping mechanism, in some in­stanes also raising the said hopper to a given height, for emptying it when full.
  • This ensemble is mounted on a frame endowed with wheels and means for moving it, as well as suitable gearings for driving the endless screen, the beating device, the vibrators and the hopper.
  • the invention aims to increase the efficiency of the machine together with a substantial reduction of the height of the hopper elevating mechanism in its rest posi­tion.
  • the machine includes at least a second revolving beating device placed downstream of conventional beating device as regards the upper run of the screening mesh; a flexible and resistant cover over the screening mesh and at a short distance thereof, the dimensions of the cover corresponding to those of the upper or working run of the said screening mesh, the ends of the cover being somewhat more spaced apart from the screening mesh such that the lower end ter­minates at about the height of the second beating device while the upper end terminates at the upper portion of the hopper loading opening.
  • a further feature of the invention resides on the fact that the upper working run of the screening mesh, is supported by a plurality of revolving rollers placed transversely to the direction of movement of the said mesh and having a cross section with an elongated outer con­tour, thus forming opposite protrusions along its whole length, which successively strike the mesh upper run.
  • the vibrating devices are formed of revolving rollers provided with lon­gitudinal flanges or clamps securing hard rubber profiles such that they are easily released and replaceable, and successively strike the screening mesh.
  • the hopper in mounted in oscillating position about a virtual axis the ends of which are supported on the ends of side arms in­tegral with a support structure for the hopper, the said arms carrying articulated the ends of two parallel arms, in turn articulated at their opposite ends on the upper portion of the machine frame, thus forming at either side of this latter an articulated polygon for raising the hop­per and which is operated by corresponding pressure fluid rams.
  • the oscillation axis of the hopper is located over the center of gravity of the hopper, such that this latter tends to assume the loading position, with its opening at the height of the upper portion of the screening mesh.
  • This machine comprises a leading beating device 3 constituted by radial fingers in the shape of wire springs (Fig. 2), placed im­mediately above a collecting ramp or blade 4 which sinks into the sand to be treated.
  • the machine is provided, just next to the ramp 4, with a screen 5 constituted by an end­less mesh which is suspended over a motor roller 6, several intermediate guide and support rollers 7 and an upper roller 8 placed at the height of a tilting, loading and unloading hopper 9 to which the larger stones and bodies collected by the blade 4 and ascending along the screen 5, are made to go.
  • the motor roller 8 is driven by any suitable mechanism such that the upper run of the screening mesh 5 moves upwards, that is, from the ramp 4 to the hopper 9.
  • the beating device 3 is made to rotate in the clockwise direction.
  • a second beating device 10 is located over the lower end of the screening mesh 5, at a short distance of the first beating device 3, and is formed, in a feasible embodiment, of a shaft 11 from which a plurality of elastic blades 12, to advantage made of hard rubber, depart and are located radial along the generatrix of the shaft 11.
  • a flexible and resistant cover 13 is located over the upper run of the screening mesh 5 and has dimen­sions corresponding to those of the above said mesh run.
  • the lower end 13a and upper end 13b of the cover are noticeably spaced apart from the mesh 5, whereas the remainder of the cover is locates very close to the mesh.
  • the lower end 13a is located somewhat higher than the beating device 10, and the upper end 13b is located over the opening 9a of the hopper 9.
  • the upper run of the screening mesh 5 rests also onto rotating rollers 14 having elastic blades 15 secured thereto by means of longitudinal clamps 16 departing in secant position from the rollers (Fig. 3), such that, upon revolving, the blades strike abruptly the bottom face of the upper run of the screening mesh 5 at several places along its path, between the support and driving rollers 6,7,8, thus imparting to it a vibration enhancing the screening action of the mesh and breaking up the soggy sand.
  • rollers showing in cross section an es­ sentially elliptic outline and lined with hard rubber, could be mounted, according to an alternative embodiment, in place of the above described rollers, and would act just in the same manner as these latter.
  • the drive of the beating devices 3,10 is per­formed by means of a pulley and belt gear generally denoted with 17 and located at one side of the machine frame 1, whereas the displacement of the screening mesh 5 and the rotation of the vibrators 14,15 is performed by means of a pulley and belt gear, not shown, located at the opposite side of the frame 1.
  • the machine frame has two rear uprights 16 at respective sides of the frame, and a respective pair of parallel arms 17 extending from the rear of the machine are articulated on the upper portion of these uprights at one of their ends, whereas the opposite ends of each said pair of arms are articulated to a respective side prop 18.
  • Both props 18 are joined by a crossbar 19, and their upper ends bear respective stub shafts 20 directed to one another and aligned transversely to the machine, upon which the hopper 9 rests in articulated relation by means of complementary bearing members not visible in the draw­ings.
  • the ensemble thus forms an elevating support for the hopper 9 which can be moved by the articulated polygon mechanism constituted by the uprights 16, arms 17 and props 18, from the working position shown in Figure 1 to the dumping position drawn in solid lines in Figure 4. Thereafter, the hopper 9, in its raised position, can be dumped onto a lorry or container according to the arrow in Figure 4.
  • the virtual axis formed of the two stub shafts 26 secured to the props 18 and their complementary bearing devices of the hopper 9 is located over the gravity center of this latter.
  • the pairs of arms 17 are operated by means of pressure fluid rams 21 having one end articulated at a point 22 of the frame 1 and the opposite end articulated at a point or axis 23 located at respective side elbows 24 integral with one of the arms of each pair.
  • the hopper is dumped by means of single action pressure fluid rams 25 having one end ar­ticulated on a point or axis 26 of each arm 18 and the op­posite end on a point or axis 27 of the hopper.
  • the stones and bodies thrown downstream of the screening mesh by the first beating device 3 are further thrown by the second beating device 10, whose blades 12 push them upwards. It is thus avoided that the larger bodies can roll down over the mesh, thus allowing to increase the slope of this latter and its efficiency as regards the room taken by the screen.
  • the flexible cover 13 catches the stones, prevent them from bouncing and help in its raising until they are discharged in the hopper 9 through the opening 9a thereof. On the other side, the said flexible cover damps the noises made by the stones and other bodies in its bouncing within the machine.
  • the vibrators 14,15 hit in an abrupt and successive man­ner, twice each complete turn, different transverse sections of the mesh 5 and break up the sand entering in a soggy condition in the machine thus contributing to the cleaning and screening of the same.
  • the rubber blades 15 of the vibrators 14,15 can be re­placed when they become worn away.
  • These vibrators 14,15 surpass to advantage the hitherto known vibrators which are formed by off-center rollers giving to the mesh an undulating movement rather that sudden blows, which is not enough to break up the sand.
  • the raising ensemble constituted by the pairs of articu­lated arms 17, which together with the props 18 and the upper portions of the uprights 16 form respective articulated polygons, provides for placing the hopper 9 at the suitable height for dumping the contents thereof in the box of a lorry or the like (Fig. 4) al­though the height of the machine frame does not prac­tically surpass the overall height of the frame when the hopper occupies its lower position (Fig. 1 and 2). This is important because the machine has a maximum overall height noticeably lower than the hitherto known machines, such that it can be lodged within standard height containers for its transportation.
  • the machine allows also, by slightly moving the arms 17 of the machine frame a short distance from the uprights 16, to dump the hopper 9 at a small height over the floor, as indicated in dot lines on the bottom half of Figure 4. It is also worthy of being outlined the easiness with which, by using single action rams, the hopper 9 recovers its loading position when its contents has been dumped, because the rotation virtual axis of the hopper, formed by the stub shafts 26, is located over the center of gravity thereof, such that the said hop­per tends to reassume its stable loading position.
