Definitions

  • This presentation concerns a construction site machine configured for pumping and/or mixing pasty and viscous products such as mortars, concretes, fluid screeds, and more generally all fluid products used in the field of building and construction.
  • construction machines are typically used to pump and/or mix fluid, pasty and/or viscous products, such as mortars, screeds, cements or even concretes, in order to supply the needs of the construction site for such products.
  • Such a construction machine 81 takes the form of a trailer fitted with wheels 82 and a hitch system 83. It includes a chassis 84, a pumping device 85 and a distribution module 86. It also includes a hopper 87, mounted on the chassis 84, closed by a lifting cover 88 in which an opening 89 is made.
  • This hopper 87 is intended to receive a fluid product to be distributed on a construction site, for example a screed.
  • a mixer truck thus supplies this hopper 87 with product through the opening 89.
  • a screen 90 is provided at the top of the hopper 87 in order to retain any large undesirable particles such as stones.
  • Such a construction machine 81 also includes a drive device 91 mounted in the chassis 84, associating a thermal engine, for example of the diesel type, with a hydraulic machine.
  • the output shaft 92 of this drive device is coupled to a transmission shaft 93 using a first coupling part 94.
  • the transmission shaft 93 carries transmission means 93a intended to facilitate the transport of the fluid product towards the outlet orifice of the hopper 87.
  • these means of transmission take the shape of an Archimedes screw 93a but it could also be pallets, to cite only these examples.
  • a vibrator 94 is mounted on one of the sides of the frame 90a carrying the grid 90.
  • Such a vibrator 94 makes it possible to animate the grid 90 with a vibratory movement allowing to facilitate the flow of the fluid product.
  • the vibrator due to its position along the grid, the vibrator is exposed to possible projections of the fluid product, or of solid elements present in the latter, which can damage the vibrator or even an element providing the energy necessary for the operation of the vibrator, an electric cable for example.
  • This presentation concerns a construction machine, configured for pumping and/or mixing fluid, pasty and/or viscous products such as mortars, concretes and fluid screeds, comprising a chassis, a receptacle, mounted on the chassis, defining a reception volume and an introduction opening opening into the reception volume, a screen, mounted in a removable or retractable manner relative to the chassis, having a working position in which the screen extends over the introduction opening , and a vibration source, in which the vibration source is mounted on the frame, remote from the screen, and in which the vibration source is configured to transmit to the screen, when the screen is in its working position, a vibratory movement via a vibratory transmission comprising a disengageable connector.
  • this disengageable connector it is possible to deport the vibration source while preserving the removability or retractable nature of the screen in order, in particular, to be able to easily access the interior of the receiving volume without it being necessary to dismantle the screen or another element transmitting the vibratory movement.
  • the vibration transmission and in particular the disengageable connector, is configured to maintain the connection between the vibration source and the screen under the sole effect of the weight of the screen. In other words, no tools or any manipulation of the disengageable connector are necessary to establish and maintain the connection once the screen is installed in the working position. This greatly facilitates the use of the machine, particularly when it is desired to remove or retract the screen.
  • the vibration transmission and in particular the disengageable connector, comprises a quick fixing device making it possible to maintain the connection between the vibration source and the screen.
  • This quick fixing device may in particular include a latch, a pin or even an eccentric handle. In such a case, establishing and breaking the connection can be done simply and easily, by simply manipulating the quick fixing device, without having to use any tool.
  • the vibration transmission and in particular the disengageable connector, comprises a bolted fixing.
  • the disengageable connector comprises a female part, secured to an element among the vibration source and the screen, and a male part, secured to the other element among the vibration source and the screen, configured to engage in the female part.
  • the connection can be established simply and quickly by simply engaging the male part in the female part.
  • the female part is attached to the vibration source and the male part is attached to the screen. In this way, it is easier to establish the connection of the disengageable connector when placing the screen in its working position.
  • the female part and the male part of the disengageable connector each have a frustoconical portion.
  • a frustoconical shape facilitates engagement of the male part in the female part and guarantees at least one point of contact between the female part and the male part.
  • said frustoconical portions are frustoconical in revolution; in other words, they are truncated cones of revolution.
  • said frustoconical portions are truncated pyramids, for example with 3 or 4 faces.
  • the taper of the female part is substantially equal to the taper of the male part.
  • the cone angle formed by the male part is between 3 and 50°, preferably between 15 and 35°, more preferably between 20 and 30°. These angle ranges make it possible to reduce, or even completely eliminate, the appearance of parasitic vertical movements of the screen. Indeed, the inventors noted that the frustoconical shape of the disengageable connector could cause, under the effect of vibrations, a vortex movement of the male part of the connector within the female part: the male part then tends to move up the along the female part before going back down, which generates a significant noise and high energy loss reducing the efficiency of the vibration source.
  • the cone angle formed by the female part is between 3 and 50°, preferably between 15 and 35°, more preferably between 20 and 30°.
  • the contact material of at least one element among the female part and the male part of the disengageable connector is softer than the contact material of the other element among the female part and the male part.
  • Vickers hardness can for example be used. This makes it possible to reduce the wear of the disengageable connector or, at least, to favor the wear of one of the parts of the connector compared to the other.
  • the softer material may be that of the female part.
  • one may be a polymeric material, of the plastic type for example, that is to say non-elastomeric, while the other may be a metal, stainless steel for example.
  • the female part of the disengageable connector comprises a contact pad made of polymeric material, of the plastic type for example, that is to say non-elastomeric.
  • a trim makes it possible to attenuate the noise generated by possible parasitic movements of the connector.
  • Such a trim can also be removable, which facilitates its replacement in the event of wear.
  • At least one of the parts of the disengageable connector is provided on one of the side walls of the screen, preferably its rear surface.
  • this part can be carried by a bracket projecting from the surface of the screen.
  • the part of the disengageable connector secured to the screen is centered laterally in relation to the center of gravity of the screen. In this way, the transmission of the vibratory movement to the screen is facilitated. In particular, the appearance of parasitic moments which can cause parasitic movements and therefore additional noise and energy loss reducing the efficiency of the vibration source is reduced.
  • the part of the disengageable connector secured to the screen is centered in elevation relative to the center of gravity of the screen. In this way, the transmission of the vibratory movement to the screen is facilitated. In particular, the appearance of parasitic moments which can cause parasitic movements and therefore additional noise is reduced.
  • the vibration source is mounted floating relative to the chassis, preferably via shock absorbers.
  • shock absorbers can in particular be of the silent block, spring or even rubber cylinder type.
  • the vibration source is mounted on the chassis via a console mounted on the chassis in a floating manner, preferably via shock absorbers.
  • shock absorbers can in particular be of the silent block, spring or even rubber cylinder type. In this way, we prevent the vibrations generated by the vibration source from propagating to the chassis.
  • the vibration source can for its part be rigidly mounted on the console.
  • the part of the disengageable connector secured to the vibration source is provided on the console. This part can for example be located at the end of an arm extending towards the front of the machine.
  • the console is a substantially flat part extending in a horizontal plane.
  • the console has at least three, and preferably exactly three, attachment points, not aligned, with the chassis.
  • At least one console attachment point secures the console from below and at least one console attachment point secures the console from above. In this way, the shock absorbers of all the attachment points act in compression, which tends to perpetuate them.
  • the center of gravity of the screen is positioned substantially in the horizontal plane of the console when the screen is in its working position. In this way, the transmission of vibratory movement in the sieve is facilitated. In particular, the appearance of parasitic moments which can cause parasitic movements and therefore additional noise is reduced.
  • the vibration source is configured to generate vibrations in a horizontal plane.
  • the vibration source is a pneumatic or electric vibrator.
  • the center of gravity of the vibration source is positioned substantially in the horizontal plane of the console. In this way, the transmission of the vibratory movement to the screen is facilitated. In particular, the appearance of parasitic moments which can cause parasitic movements and therefore additional noise is reduced.
  • the screen is pivotable relative to the frame. This allows easy access to the interior of the receiving volume.
  • the screen is configured to pivot about a horizontal axis, preferably about the right-left direction of the machine.
  • the screen may comprise bearings arranged at its side opposite the disengageable connector, preferably at its front side.
  • each bearing includes a shock absorber: each bearing can also be carried by a support mounted on a shock absorber.
  • the screen is removable and interchangeable. Beyond being able to provide access to the interior of the reception volume, this makes it possible to easily change the screen depending on the product used, for example.
  • the screen is mounted floating relative to the frame, preferably via shock absorbers.
  • shock absorbers can in particular be of the silent block, spring or even rubber cylinder type.
  • the screen is carried by the chassis in its working position via at least three support points, and preferably exactly three support points.
  • two support points of the screen are formed by bearings.
  • a support point of the screen is formed by the disengageable connector.
  • the screen rests on the disengageable connector when it is in its working position.

  • FIG. 3 illustrates an example of construction machine 1 according to the presentation.
  • This construction machine 1 takes the form of a trailer fitted with wheels 2 and a hitch system 3. It comprises a chassis 10, a pumping device 20 and a distribution module 30.
  • the construction machine 1 also includes a hopper 11, mounted in the chassis 10 and intended to receive a fluid, viscous and/or pasty product brought by a mixer truck.
  • a screen 40 is provided at the top of the hopper 11, allowing, in addition to its safety and protection function against rotating elements, to retain any large undesirable particles such as stones.
  • This screen 40 comprises a rectangular frame 41, formed of four side walls 41a-41d, and a plurality of angles 42 extending between the left side walls 41b and right 41d of the frame 41. These angles 42 are rectilinear and extend all parallel in the same plane; they have a chevron shape with the edge pointing upwards.
  • the screen 40 is pivotally mounted on the chassis 10 via bearings 43 provided at the front of the frame 41, more precisely at the front end of the left side walls 41b and right 41d.
  • These bearings 43 have the particularity of being floating, that is to say they have a damping member making it possible to reduce the transmission of parasitic movements such as vibrations between the screen 40 and the chassis 10.
  • the screen 40 can be pivoted between a horizontal working position, shown on the Figure 3 for example, in which it is interposed in front of the introduction opening of the hopper 11, and a raised position, shown on the figure 4 for example, in which it is raised in a vertical position, or beyond the vertical, and thus leaves free access to the interior volume of the hopper 11.
  • the construction machine 1 also includes a vibration system 50 including a vibrator 51 forming a vibration source.
  • the vibrator 51 is an electric vibrator having a vertical axis on which an eccentric flyweight is provided. It therefore produces a vibratory movement propagating essentially in the horizontal plane. This vibratory movement is transmitted to the screen 40 via a vibration transmission.
  • the vibration system 50 also includes a console 52, forming part of this vibration transmission, allowing the fixing of the vibrator 51 on the chassis 10.
  • This console 52 takes the form of a planar frame having three uprights, a front upright 53a and two uprights lateral 53b, 53c, organized in an isosceles triangle.
  • the vibrator 51 is rigidly fixed on a fixing portion 54 of the console 52 provided at the intersection of the two side uprights 53b, 53c.

  • This fixing is also ensured in a floating manner by means of a shock absorber 56 of the silent block type.
  • the vibrations produced by the vibrator 51 do not propagate, or practically not, to the chassis 10.
  • the vibratory movement of the vibrator 51 is on the other hand transmitted to the screen 40, when it is in its working position, via a disengageable connector 60.

  • This ring 67 is a trim fitted into a cavity 57 of the console 52, this cavity 57 being provided at the end of an arm 58 extending forwards from the middle of the front upright 53a of the console 52.
  • this ring 67 is made of hard plastic, more precisely PA6.
  • the finger 62 engages in the ring 67, which connects the screen 40 to the vibratory system 50: the vibratory movement of vibrator 51 can thus propagate up to the screen 40 .
  • the position of the finger 62 is designed to be located substantially on the front-rear axis passing through the center of gravity of the screen 40.
  • the ring 67 and more generally the entire console 52, is designed to be located substantially in the horizontal plane passing through the center of gravity of the vibrator 51. In this way, when the screen 40 is in its working position, the vibratory movement of the vibrator can propagate to the screen while minimizing the losses of energy and the appearance of parasitic moments.
  • the disengageable connector 60 then forms a third point of support for the screen 40 when it is in its position of work.
  • the weight alone of the screen 40 makes it possible to effectively maintain the connection of the disengageable connector.
  • the construction machine takes the form of a trailer mounted on wheels but it goes without saying that it could also be fitted with skids to simply be placed on the construction site or even that it could be mounted in a vehicle.
  • the machine performs both a mixing function and a pumping function of the fluid product but it goes without saying that it could only perform one of these functions, for example only mixing. .
