Definitions

  • the present invention relates to a machine for mixing and pumping mortar, cement mixes, and similar.
  • machines for mixing and pumping mortar, cement mixes, and similar normally comprise a mortar tank having a top opening for loading the material to be pumped, and a cover hermetically closing the opening; a screw or other mixing member mounted to rotate axially inside the tank; and a pump assembly for pumping the mortar out of the tank at a predetermined pressure and/or flow rate.
  • Known pumping machines also comprise a drive unit for driving the pump assembly and the mixing member; and a movable loading bucket hinged to the machine frame, or rather the machine tank, to rotate between a lowered position, in which it is located alongside the tank, resting on the ground, and can be loaded with the material for forming the mortar, and a raised position, in which the movable bucket is positioned upside down over the tank, with its outlet aligned with the tank opening, to discharge all the material in the bucket into the tank.
  • most known machines for pumping mortar and similar comprise a hopper hinged to the machine frame to rotate freely about the same axis of rotation as the movable bucket, and interposed between the tank opening and the movable loading bucket, so as to be interposed between the tank opening and the bucket outlet when the bucket is in the raised position.
  • the tank opening is covered with a removable guard grille to prevent access by the operator to the inside of the tank containing moving parts.
  • the guard grille must obviously be sized so that the through openings are small enough to at least prevent insertion of the operator's hand. This, however, poses serious drawbacks when filling the tank, in that the material from the outlet of the movable bucket tends to accumulate on the guard grille and soon clogs the tank opening completely, with all the drawbacks this involves. The operator, in fact, is forced to repeatedly clear the grille during each filling operation, thus wasting valuable time.
  • a machine for mixing and pumping mortar, cement mixes, and similar comprising a tank having an inlet through which to pour into the tank the various component materials of the mortar for pumping; a movable loading bucket hinged to the frame of the machine to rotate about a substantially horizontal dump axis; and an actuating device for moving said movable bucket, on command and about said dump axis, between a lowered position, in which the movable bucket is located alongside the tank, and a raised position, in which the movable bucket is positioned upside down over the tank, with the outlet of the movable bucket aligned with the inlet of said tank; said machine for mixing and pumping mortar, cement mixes, and similar also comprising a guard grille closing the inlet of the tank, and being characterized by also comprising vibrating means for vibrating said guard grille on command.
  • Number 1 in Figures 1 and 2 indicates as a whole a machine for mixing and pumping mortar, cement mixes, and similar, and which substantially comprises a mortar tank 2 having a top inlet 2a through which it is possible to pour into the tank the various component materials of the mortar for pumping; a mixing member (not shown) fitted movably inside tank 2 to mix the mortar continuously; a pump assembly 3 for pumping the mortar out of tank 2 at a predetermined pressure and/or flow rate; and a drive unit 4 for driving the mixing member and pump assembly 3.
  • tank 2 comprises a cylindrical, substantially horizontal vessel 5 having, on top, a cylindrical tubular stack or collar 5a projecting vertically from the central body of the vessel to form the inlet 2a of tank 2, and a movable cover 6 for closing the top end of tubular collar 5a and so closing inlet 2a of tank 2 hermetically.
  • movable cover 6 is hinged directly to the side of tubular collar 5a to rotate freely, about a horizontal axis of rotation, to and from an operating position resting on the top end of tubular collar 5a to close inlet 2a of tank 2 hermetically.
  • machine 1 also comprises a movable loading bucket 7 hinged to the frame of machine 1, or rather to tank 2 of the machine, to rotate about a horizontal dump axis A located preferably, though not necessarily, alongside tubular collar 5a; and an actuating device 8 for moving movable bucket 7, on command and about axis A, between a lowered position (shown by the dash line in Figure 1), in which movable bucket 7 is located alongside tank 2, resting on the ground, and can be loaded with the material for forming the mortar, and a raised position (shown by the continuous line in Figure 1), in which movable bucket 7 is positioned upside down over tank 2, with the outlet 7a of the movable bucket aligned with inlet 2a of tank 2, to discharge all the material in movable bucket 7 by gravity into tank 2.
  • a movable loading bucket 7 hinged to the frame of machine 1, or rather to tank 2 of the machine, to rotate about a horizontal dump axis A located preferably, though not necessarily, alongside tubular collar 5a
  • actuating device 8 is defined by a hydraulic, single- or double-acting piston hinged at one end to tank 2 and at the other end to movable bucket 7.
  • machine 1 preferably, though not necessarily, also comprises a hopper 9 hinged to the frame of machine 1, or rather to tank 2 of the machine, close to inlet 2a, so as to rotate freely, about a horizontal axis of rotation, to and from an operating position, in which hopper 9 is partly inserted inside inlet 2a of tank 2, i.e. inside tubular collar 5a, and is interposed between outlet 7a of movable bucket 7 and inlet 2a of tank 2 when movable bucket 7 is in the raised position ( Figure 1).
  • hopper 9 is partly inserted inside inlet 2a of tank 2, i.e. inside tubular collar 5a, and is interposed between outlet 7a of movable bucket 7 and inlet 2a of tank 2 when movable bucket 7 is in the raised position ( Figure 1).
  • hopper 9 is hinged to tank 2, so that the horizontal axis of rotation of the hopper is coincident with dump axis A of movable bucket 7, and substantially comprises a substantially truncated-cone-, funnel-shaped body 10 with an outlet, i.e. smaller-diameter opening, sized to fit inside tubular collar 5a; and two parallel, facing arms 11 for connection to the frame, and which project from funnel-shaped body 10, and are hinged at the ends to the frame of machine 1 along dump axis A of movable bucket 7.
  • Tank 2 pump assembly 3, drive unit 4, movable bucket 7, hydraulic piston 8, and hopper 9 are commonly used component parts in this particular field, and therefore require no further description.
  • machine 1 also comprises a removable guard grille 12 for closing inlet 2a of tank 2; and a vibrating member 13 for vibrating guard grille 12, on command, to prevent material settling on the grille when being dumped into tank 2.
  • guard grille 12 is defined by a flat, disk-shaped lattice structure which is sized to fit crosswise inside tubular collar 5a defining inlet 2a of tank 2, and is hinged to the wall of tubular collar 5a to rotate freely - about a horizontal axis of rotation B preferably, though not necessarily, parallel to the axis of rotation of movable cover 6 - between a first operating position, in which flat lattice structure 12 is positioned horizontally, closing tubular collar 5a and, hence, inlet 2a, and a second operating position, in which flat lattice structure 12 is positioned substantially vertically (Figure 2) to allow free access to the inside of tank 2 for routine maintenance.
  • guard grille 12 is hinged to the wall of tubular collar 5a defining inlet 2a of tank 2, with the interposition of an elastic joint 14 designed to prevent the vibration of guard grille 12 being transmitted to tank 2 and, hence, to the rest of machine 1.
  • vibrating member 13 is fixed rigidly and directly to guard grille 12, and is defined, in the example shown, by an electric, hydraulic, or pneumatic motor fixed appropriately to guard grille 12, and by one or more rotating masses fitted to the output shaft of the motor so that the centre of gravity of the mass is eccentric with respect to the axis of rotation of the shaft, and so as to vibrate the entire structure when the mass is rotated by the motor; the whole being enclosed in a known protective outer casing.
  • machine 1 for mixing and pumping mortar, cement mixes, and similar as described and illustrated herein, without, however, departing from the scope of the present invention.
  • vibrating member 13 may be fixed rigidly to hopper 9, which, in this case, comprises retaining means for selectively making guard grille 12 integral with hopper 9 when the hopper is inserted partly inside tubular collar 5a in the operating position.
  • the retaining means comprise a retaining plate 15 made of ferromagnetic material and fixed rigidly to guard grille 12; and two electromagnets 16 fixed rigidly to hopper 9 to rest on retaining plate 15, when hopper 9 is inserted partly inside tubular collar 5a, in the operating position, thus making guard grille 12 integral with hopper 9.
  • electromagnets 16 may be replaced with permanent magnets or other mechanical retaining systems, such as two pins projecting from hopper 9 and which engage seats, formed in retaining plate 15, when hopper 9 is inserted partly inside tubular collar 5a, in the operating position.
  • hopper 9 is hinged to the frame of machine 1 with the interposition of elastic joints designed to prevent the vibration of hopper 9 from being transmitted to tank 2 and, hence, to the rest of machine 1.
  • each of the two arms 11 connecting hopper 9 to the frame is divided into two portions, and hopper 9 has two elastic joints 17, each for connecting the two portions of a relative arm 11 connecting the hopper to the frame.
  • guard grille 12 is fixed rigidly to, and closes, the outlet of funnel-shaped body 10, and vibrating member 13 is fixed directly to the outside of funnel-shaped body 10, and vibrates, on command, the whole defined by funnel-shaped body 10 and guard grille 12, to prevent material from settling on guard grille 12 when filling tank 2.
  • guard grille 12 obviously closes inlet 2a of tank 2 when hopper 9 is in the operating position.
  • each of the two arms 11 of hopper 9, projecting from funnel-shaped body 10 to connect the funnel-shaped body to the frame of machine 1 along axis A, is divided into two portions connected by a respective elastic joint 17.
  • machine 1 also comprises an auxiliary guard grille 18 fixed permanently to tank 2 to close inlet 2a of the tank, and guard grille 12 is positioned parallel to and facing auxiliary guard grille 18 when hopper 9 is in the operating position.
  • auxiliary guard grille 18 is defined by a flat, disk-shaped lattice structure 18, which is sized to fit crosswise inside tubular collar 5a defining inlet 2a of tank 2, and is hinged to the wall of tubular collar 5a to rotate freely - about a horizontal axis of rotation C preferably, though not necessarily, parallel to the axis of rotation of movable cover 6 - between a first operating position, in which flat lattice structure 18 is positioned horizontally ( Figure 5), closing tubular collar 5a and, hence, inlet 2a, and a second operating position, in which flat lattice structure 18 is positioned substantially vertically to allow free access to the inside of tank 2 for routine maintenance.
