  • Another goal was to design an installation that could be easily removable, transportable and movable and able to adapt to all land profiles and in particular storage and sampling areas components, such as gravel, sand.
  • Another goal sought lies in the operation of the installation which is not polluting, in particular thanks to a device for recycling of washing water into mixing water.
  • said installation is characterized in that it comprises in its central part, a structure forming a frame (Bt) from which are positioned from top to bottom, means (R1, R2, V) distributing materials from three areas sampling (Z2, Z3, Z4), gravel, sand, cement, mixer of different materials, said mixer (M) being arranged with outlets to allow the distribution of mixed products to three zones different packaging (T1, T2, T3), in bulk, in bags or in flexible containers, underlying the mixer and plumb, being disposed a water tank (R) which is capable of enabling by means suitable water distribution in the mixer (M) in order to obtaining the products to be distributed, and means allowing recycling water in continuous cycle, said frame being further arranged to receive means allowing the distribution of mixed products to the different types of packaging.
  • the invention aims to implement a compact installation of small dimension and allowing in a reduced space volume the treatment concrete or mortar orders managed by card from the cabin technical (CT) at the request of the user under the conditions described in PCT patent WO 98/22271.
  • the installation includes, in its central part, a structure forming a frame (Bt) from which are positioned from top to bottom, means (R1, R2, V) distributing materials from three areas sampling (Z2, Z3, Z4), gravel, sand, cement, mixer of different materials, said mixer (M) being arranged with outlets to allow the distribution of mixed products to three zones different packaging (T1, T2, T3), in bulk, in bags or in flexible containers.
  • a water tank (R) which is capable of enabling by means suitable water distribution in the mixer (M) in order to obtaining the products to be distributed, and means allowing recycling water in continuous cycle.
  • the frame (Bt) is made up of large uprights height and joined together by spacers to give it its rigidity.
  • the frame In its upper part, the frame is likely to receive the mixer (M) which is formed in the form of a cylindrical tank by example of large capacity and which receives the different materials, sand, cement, gravel, previously dosed to build up mortar or concrete, in the characteristics ordered by the customer with the additives appropriate.
  • M the mixer
  • Said mixer has at its bottom three flaps (1A, 1B, 1C) articulated arranged opposite three means of product evacuation mixed according to three types of desired packaging corresponding to those described in the aforementioned PCT patent. These components are articulated and locked in position using means known to those skilled in the art.
  • the mixer tank is also likely to receive in its part upper a support arm (2) controlled in rotation in the volume of the mixer by a suitable motor means (2b); the support arm has blades (2a) which are liable to stir the various components of the mixture to be obtained.
  • the tank has in its upper part a support structure (3) of an agitating means (4) with blades (4a) controlled by a motor (5) and intended to stir the water in The reservoir.
  • This circular agitator keeps suspended in water the fines contained in the wash water.
  • a pump (6) suction submerged in the tank allows through a flexible duct (7) take water for delivery and distribution by the party upper part of the mixer tank (M) therein.
  • a metering means (8) located above the mixer by being fixed to the frame in any suitable manner. This way metering device (8) measures the volume of water to be distributed in the mixer; this volume is a function of the order placed for mortar or concrete by the user, taking into account the particular characteristics of the desired mixture.
  • Another particular provision of the invention resides in the fact at the outlet of the mixer, to condition flexible container bags large capacity (300 to 500 Kg called BIG BAG), it is planned to have a chute (9) for evacuating the products to a carriage (10) for receiving and moving, supporting said flexible containers (11).
  • This chute is hingedly attached to the frame structure, as shown in Figure 9 of the drawings.
  • This articulation is established in the form of a yoke (12) for example with the locking means in the appropriate position.
  • This chute has a trough shape. According to a first position, within the framework of the normal operation of the installation, it is susceptible by its lower end (9a) to open opposite the support carriage flexible containers, while its upper end (9b) is in outlet of one of the flaps (1c) of the mixer (M).
  • the chute is pivoted so that its lower end (9a) is oriented in direction of the tank (R).
  • the mixer is for this purpose arranged with means (13) for distributing water using ramps and spray nozzles to allow its interior cleaning. In this situation, the water from cleaning collected in the mixer (M) is discharged through said chute (9) and sprayed inside the tank (6).
  • a conveyor belt (T1) shown in Figure 2 of the drawings, is articulated at one end to the frame (Bt), using any suitable means (14).
  • This first end of the conveyor is opposite the outlet of a first flap (1a) of the mixer (M) and is capable of receiving thanks to a trough (15) for distributing the products.
  • the other end of the conveyor arranged with a distribution hopper (16), is arranged adjustable in height relative to a support structure (17) in order to orient and position said conveyor in height as a function of the vehicle (18) of loading of bulk products, and adapting its position so as not to project in poor conditions the products collected.
  • the frame is likely to receive in its lower part under the mixing device (M) and in an area adjacent to the tank (R) a complementary device (D) allowing the packaging of mixed products in bags of capacity of the order of 20 to 40 kg.
  • a buffer hopper (19) for receiving the products.
  • This hopper opens into its lower part on a drive means (20) consisting of a screw endless, soulless (20a) for conveying said products to the bagging device.
  • This hopper (19) is arranged on one of its walls (19a) with a plate (21) capable of being animated with a movement back and forth to break the arch effect and get a good lowering of the product inside the screw. This back and forth movement is obtained by the fact that the plate has a protruding base (21a) projecting outwardly from the hopper and being coupled to the rod (22a) of a pneumatic cylinder (22).
  • An opening (19b) is provided on the wall in sight of the hopper to allow said movement back and forth according to the arrow (F) (figure 10).
  • the cylinder body (22) is secured to a plate support (23) integral with the wall of the hopper.
  • Said plate presents protruding shapes (21b) passing through complementary openings (19c) established in the wall of the hopper.
  • the displacement of the cylinder rod as shown in Figures 10, 11 and 12 of the drawings, provides the desired effect and facilitate the flow of products contained in the hopper inside the screw without segregation or compaction.
  • a semi-cylindrical trough (24) is provided under the lower part of the hopper.
  • This is controlled by an engine block (25) disposed behind the hopper and positioned on a support plane (26) of the frame.
  • the gauge can be arranged directly or attached with an inner wall made for example of a material known as "Teflon" mark to ensure better resistance to wear.
  • the opinion endless, soulless, is articulated on its single bearing (27) in order to rest on the bottom of the trough to extract all of the product.
  • the conveyor exit leads to a known device (28) bagging.
  • the bags (29) with a capacity of the order of 20 to 40 kilos per example are positioned by their upper border (29a) on the outlet of the bagging device which includes an expander means (30) allowing to keep said bags open when they are filled. Movement reciprocating back and forth from the plate can be obtained by other means equivalent.
  • the scraper chains have an L-shaped support structure (31) around which is likely to move the bucket chain.
  • Each L-shaped support structure includes two sets of arms (31a) (31b), one oriented upwards obliquely, the other horizontal, being articulated one to the others in their connecting part (31c).
  • the upper arms facing the top are themselves arranged in two parts (31a1) (31a2) connected by screws (32) for inverted pitch connection and nut (32a) for intermediate adjustment.
  • a tie rod (33) is capable of coupling to each sets of said arms in an articulated and pivoting manner using the appropriate means of connection.
  • This tie rod is itself in two parts (33a) (33b) arranged in alignment and allowing the insertion of a screw (34) with pitch inverted and adjusting nut (35).
  • This double adjustment provision allows thus to best adapt the position of the scraping chains according to the conformation of the soil, with fine and continuous adjustments, and allow during operation of the installation easy removal of materials.
