Definitions

  • the machine according to the invention is designed for mixing mortar.
  • Mortar is known to be a mixture of lime putty, sand, cement and water, which because of its plasticity and workability characteristics is widely used in finishing operations on curtain walls and load- bearing walls, and in the repair and restoring of surfaces after work resulting from the installation of electrical, hydraulic, heating and other systems.
  • the present invention allows the true mechanical mixing of mortar in the required quantity.
  • the new mortar mixing machine is constituted essentially by an outer sheet metal casing, of which the lower part is of semi-cylindrical cross-section and the upper part is of hopper configuration, and is connected to the preceding part by a continuous connection.
  • an electrically driven shaft on which are disposed two helical surfaces mounted on suitably arranged supports and having a certain radius and a certain pitch, their purpose being to impress on the mass to be mixed an opposing helical movement, as the two spirals are in mutual opposition.
  • This system produces perfect mixing of the semi-fluid ners constituted by the lime putty, sand and water, in the required quantity and in a very short time.
  • a perforated baffle constituted by an electrically welded mesh which has the double purpose of supporting bags of material which are opened and emptied into the body of the machine, and at the same time to act as a safety baffle to prevent any possible contact between the machine operator and the rotating parts therein.
  • Said perforated baffle is suitably connected to a switch system which if the baffle is opened in error while the machine is in operation automatically disconnects the motor and thus stops the movement of the helical surfaces.
  • the prepared mortar is discharged through an aperture in a position corresponding with the lower part of that side wall opposite the one on which the electric motor is mounted.
  • One cr more such machines can be mounted either on a wheel-mounted trolley of any form, or on a fixed or foldable support.
  • Figure 1 is a view of the machine on that side which comprises the finished mortar outlet 1, which is operated by the lever 2.
  • the helical surfaces 3 and 4 mounted on the shaft 3 are shown by dashed lines.
  • Figure 2 is a section through the machine casing shoving the characteristic dimensions; in particular it can be seen that the dimension E is greater than the dimension F in order to enable the helical surfaces 3 and 4 to agitate the mass contained in the zone above the connection between the hopper 7 and chamber 6.
  • FIG 2 also shows the corner supports 8 on which the protection mesh 12 rests, this being shown in Figure 3.
  • Figure 3 is a longitudinal section through the machine.
  • the drive shaft 5 on which are mounted the helical surfaces in the form of mutually opposing spirals having a pitch chosen in accordance with the radius in such a manner as to obtain optimum mixing action without either the advancing action of the mixing mass prevailing, as would happen if the pitch were too large, or the hold-up action of the mass prevailing, as would happen if the pitch were too small.
  • the drive shaft is mounted on the supports 9 and 10.
  • the support 10 is connected by a coupling to the electric motor 11, which is chosen ir accordance with the consistency of the mass to be mixed in the chamber 6 and in accordance with the radii and pitches of the helical surfaces 3 and 4.
  • Figure 4 is a plan view of the mixing chamber 6 and hopper 7.
  • the drawing also shows the shaft supports 9 and 10, the motor 11, and part of the protection mesh 12 which rests on the supports 8.
  • the mixing machine according to the present invention can be constructed of any size, and advantageously can have a capacity of between 50 and 350 litres. Moreover, as stated, it can be in the form either of a fixed installation or a portable device.
