Definitions

  • the present invention relates to the use of a semi-automatic device for screening aggregates on site.
  • Certain masonry work on site requires the sieving of sand to have a homogeneous product.
  • the present invention makes this work less strenuous, increases its output and this with effective work safety.
  • the use of a semi-automatic device characterized by the temporary introduction of a cylindrical sieve inside the mouth of the rotating tank of a concrete mixer eliminates all these drawbacks.
  • the yield is improved, a single handling with the shovel of aggregates is enough the sieved sand being found inside the concrete mixer ready for use, the large aggregates being loaded automatically in the wheelbarrow to transport them to the area of storage.
  • the operation consists of loading the aggregates into the concrete mixer in normal use but through a sieve.
  • the device according to the invention allows the screening of aggregates
  • the device comprises the cylindrical screen (X) introduced into the tank of the concrete mixer (Y).
  • the inclination of the tank is carried out at around 45 ° for optimum performance.
  • the speed of rotation of the tank being that of its normal use which is between 25 and 30 rpm.
  • the assembly rotates in the direction of the arrow (I).
  • Starting from the pile of raw sand (F) and following the trajectory (B) we load the sieve (X) by depositing the shovels of raw sand to be sieved in the region (G) of the sieve.
  • the device shown in Figure 1 includes the screen (X) composed of a rigid cylindrical body with in its lower internal part and fixed thereto the sieving fabric composed of a mesh.
  • the sieve is incorporated entirely inside the tank. It has a working surface equal to the surface of the mouth of the concrete mixer (Y).
  • This sieve will be economical, simple in shape, without fixing because the friction force of the rolled edge of the sieve on the rolled edge of the mouth of the concrete mixer is sufficient to avoid any slipping.
  • the center of gravity of the sieve, empty or loaded, located inside and below its lift surface prevents it from tipping over.
  • This sieve is reserved particularly for traditional concrete mixers for mason craftsmen and masonry enthusiasts.
  • the device according to the invention highlights the advantages of this sieve: easy and rapid implementation of the assembly, sieving of aggregates just in the quantity required, a single manipulation of the sand with a shovel is sufficient, therefore saving of time, of trouble, of aggregates. All while having maximum job security due to its integration and the absence of projecting parts.
  • the device, object of the invention can be used in all cases where sorting of aggregates is required.
