Definitions

  • the invention concerns a device and a machine for the storage and/or transport of a product for making concrete screed.
  • composition of the compound varies according to the characteristics of the screed to be obtained.
  • the compound is made by the operator on the site where the screed is to be laid, preparing first the suitable quantities of solid elements or mixtures, including sand, binders, etc, and then adding a given percentage of water.
  • the substantially liquid compound obtained in this way is first amalgamated, then uniformly spread on the surface to be treated and finally properly levelled.
  • the operator proceeds to the laying of tiles or similar coverings to obtain the desired floor.
  • the known technique involves the use of preparations, called pre-mixed products, that are constituted by the solid elements of the compound.
  • said products comprise a solid mixture substantially made up of sand and binders, which is prepared in advance and stored in special containers that are then transported to the site where the compound is going to be laid.
  • the product also comprises special additives, also called catalyzers, that are activated when placed in contact with water.
  • a first drawback posed by said containers is constituted by the fact that the product transported to the laying site is not homogeneous. This is due to the fact that the various elements making up the solid mixture naturally tend to separate during both the transport and the storage phase.
  • a further inconvenience connected to the previous one is the fact that the compound obtained by adding water does not have the optimal characteristics for making a good screed. More precisely, the compound does not contain the required percentage of each element per unit of weight. This negatively affects both the characteristics of the screed obtained and the drying time of the screed itself.
  • the known technique has proposed devices for storing said products that are equipped with mixing means inside the container.
  • Said mixing means comprise elements or blades that are properly moved inside the container in order to mix the various elements.
  • a first drawback of these devices is constituted by the fact that they do not maintain the product mixed in an optimal way. This inconvenience occurs specially during the transport of the container, when the preparation is subjected to various stresses that make the heavier elements move towards the bottom of the container.
  • the aim of the present invention is to overcome all the drawbacks described.
  • Another aim of the invention is to produce a device that can be easily transported near the laying site.
  • a device for the storage and/or transport of a product for making screeds advantageously but not exclusively a pre-mixed product, comprising:
  • the proposed solution advantageously makes it possible to store and transport the product, at the same time keeping it homogeneous and in the optimal conditions for its usage.
  • FIG. 1 An embodiment of a device subject of the invention is represented in Figure 1, where it is indicated as a whole by 1.
  • It comprises a container 2 for the preparation P and mixing means, indicated as a whole by 3, installed inside the container 2 and suited to stir the preparation or product P in order to maintain and guarantee its homogeneity during both storage and transport to the laying site.
  • the container 2 is provided with an upper opening 2a that allows the product P to be loaded and a discharge mouth 2b that can be seen in Figure 2.
  • the mixing means 3 are suited to stir the product P in opposite directions D1, D2 to mix the product P and/or make it homogeneous.
  • the mixing means 3 comprise one or more rotary augers/screws 4 in which it is possible to identify at least two thread-like parts or sections 4a and 4b with opposite thrust directions.
  • auger indicates a mechanical member comprising a substantially cylindrical or conical stem, on which one or more helical grooves are cut or where one or more helical elements/projections wound on the stem itself can be identified.
  • the augers 4 rotate and generate inside the container flows of product that move in opposite directions and produce vortices that are such as to result in a useful stirring action.
  • the device 1 comprises two augers 4 positioned near the bottom of the container 2 and facing each other in order to increase their effect.
  • each auger rotates on an axis 40, 41 that, in the case in question, lies on a substantially horizontal plane.
  • Each auger 4 is set in motion by first drive means 7 and comprises, as shown in detail in Figure 3, a cylindrical stem 5 that supports two helical elements 6a and 6b that are wound on the stem 5 in opposite directions to identify the same number of thread-like sections 4a and 4b with opposite thrust directions.
  • first drive means 7 they comprise a gear motor unit 70 associated to each auger 4.
  • the number or rotary augers and their position inside the container 2 may vary.
  • the device 1 also comprises means 8 for transporting the product, suited to take the product P from the container 2 to convey it towards the discharge mouth 2b.
  • said transport means 8 at least partially face the mixing means 3 and comprise a conveyor auger 80 positioned near the bottom of the container 2.
  • said conveyor auger 80 is positioned in a channel that develops longitudinally for the whole length of the container 2 and is set in motion by second drive means 9 comprising a second gear motor unit 90.
  • the walls 2c, 2d of the container 2 are inclined and converge towards the bottom, in correspondence of which they define the above mentioned discharge channel in which the conveyor auger 80 is positioned.
  • a construction variant of the device subject of the invention is differentiated from the previous one due to the fact that in each auger 4 there are four thread-like sections or parts, each with thrust direction opposite to that of the adjacent section.
  • FIG. 4b Another embodiment of a device according to the invention, indicated as a whole by 101 in Figure 4b, is differentiated from the previous one due to the fact that the mixing means 3 comprise only one auger positioned above the transport means 8, with which it cooperates to stir the product P.
  • a first construction variant of the mixing means 3, represented in detail in Figure 5, is differentiated from the previous one due to the fact that the helical element 6c or blade is provided with openings 10 that allow the passage of the product and thus increase the chaotic stirring motion.
  • a further construction variant of the auger 4, represented in detail in Figure 6, is differentiated from the previous one due to the fact that the helical element 6d or blade is sustained by radial supports 11 integral with the stem 5. This makes it possible to further reduce the working surface of the helically developing element, thus decreasing the mechanical effort born by the auger and by the drive means 7 that move it. This solution also makes it possible to further increase the chaotic movement of the product P inside the container 2, thus increasing the effectiveness of the device.
  • a further construction variant of the mixing means 3, represented in Figure 7, is differentiated from the previous ones due to the fact that the helical element 6e is not continuous and is divided in sections or blades 6e that define an helical trend.
  • a machine for storing and transporting a product for making screeds also subject of the invention is represented in Figure 8, where it is indicated as a whole by 500.
  • the machine 500 also comprises mixing means, indicated as a whole by 503, positioned after the discharge mouth of the device 502, cooperating with means for pumping the mixture obtained in this way.
  • the mixing means 503 comprise a tank equipped with a moving blade, inside which the product P is conveyed and water is added.
  • the pumping means comprise a compressor unit that introduces pressurized air inside the tight tank, thus causing the discharge of the compound through a discharge duct.
  • the operator once filled the container 2 with the preparation or pre-mixed product P, activates the first drive means 7 that set the augers 4 rotating.
  • augers 4 are advantageously positioned near the bottom and the inclined walls 2a, 2b of the container 2 and cooperate with the transport means 8 to increase the stirring capacity.
  • the proposed machine 500 allows the product P to be loaded and transported to the laying site, maintaining its optimal homogeneity characteristics, and also allows the compound to be made and transported to the laying site.
