Definitions

  • the invention relates to an improved device for loading, with compression, different solids in a receptacle. It relates in particular to the loading of materials, in particular garbage or waste, domestic or industrial, into a bucket.
  • the new device is applicable to different containers or dumpsters, fixed or mobile, and, more specifically, to refuse collection vehicles.
  • the devices of the type concerned by the present invention comprise mobile means, generally known by the name of shovel or flap, for pushing the materials into the receptacle; these means, mounted in a loading hopper, are moved by motor means placed symmetrically on either side, in the width direction, of the flap.
  • guides were provided for these mobile means of thrust, so as to impose the desired trajectory on the latter, during work.
  • US Patent No. 3220586 where the guides have an inclined portion and a horizontal, and define the operation of the flap in a 3- time.
  • U improvement was carried out thereafter, according to publication No. 2436092 of the French patent application: the shutter and its jacks are integral with a sliding beam on a uniformly curved guide, and the operating cycle is 4 times .
  • the present invention provides significant advantages over the corresponding prior art, both with regard to the construction of the device and the effectiveness thereof.
  • the invention allows, in fact, the loading with high compression of solid materials of all kinds, of high hourly tonnage, with a device much lighter than those of known devices; thus can orr gain, for example, 30% on the weight of the device while treating the same hourly weight of household waste, with an equivalent compression or even stronger than in the past.
  • Another advantage of the device according to the invention lies in the fact that it is possible to load materials into the hopper at any time, during operation, which resembles the device to continuous devices.
  • the invention gives excellent results in the operation of the loading means with compression according to a 4-stroke cycle, but it can be applied as well to a milker of different rhythm.
  • the mobile means for pushing and compressing the materials to be loaded are constituted by two elements, both moving in lateral guides and articulated to each other, so as to allow their translation along the guides, as well as their reciprocal pivoting.
  • the mounting is such that, during operation, these means move simultaneously, both, in a triangular configuration with respect to the means which produce this movement.
  • the device for loading materials according to the invention is of the type with compression in a receptacle from a hopper, comprising two compression elements formed by an upper element and a lower element, which can pivot one by relative to the other, around a common pivot axis, located at the lower part of the upper element, these two elements being able each moreover to pivot around a sliding axis in lateral guides, this axis being, for the upper element, located at the upper end thereof; first drive means, for example jacks moving all of the two elements in the lateral guides, and second drive means, in particular jacks making one element pivot relative to the other, these second drive means being connected to the upper end of the upper element (such a device is known from DE-A N o 2908208).
  • This device is characterized in that the first and second drive means are attached to the upper end of the lower element by an articulation which slides in the lateral guides, and that the pivot axis common to the two elements is located outside lateral guides.
  • Each of the two elements, forming the mobile loading means has a roller in the guide, at its upper end; while the articulation between them is outside the planes passing through the guides, in particular below these planes.
  • this last articulation connects the lower extremity of the upper element to the body of the lower element between approximately 1 / 3and 1 ⁇ 2 of the length of the latter counted from its upper end.
  • the drive means most often jacks, are, according to the invention, two in number arranged at the sides of the atheros of the mobile loading elements.
  • all the two pairs of motor means are connected to the upper end or head of the lower loading element; one of these pairs has its opposite end connected to the upper end of the upper element, on the guide path, while the opposite end of the second pair of motor means is articulated at the top of the wall of the device, especially on the hopper door articulation.
  • the loading elements are solid panels, the front face of which, that is to say that which faces the interior of the receptacle, preferably has a profile suitable for the pushing and compression work to be carried out.
  • the lower element constitutes a solid panel only in its lower part, below its articulation with the upper element.
  • the top of this lower element is notched, which makes it possible to load the hopper even during the operation of the device.
  • the preferred shape of the lower element is such that the section thereof by a vertical plane, parallel to the plane passing through the guides, is substantially triangular.
  • the upper element it is advantageous that it has a stepped profile, reinforcing this element and helping to retain the treated materials, when the hopper is opened.
  • FIG. 3 shows a set of two elements, 1 and 6, for loading, moving in the guide 11, with their jacks 4 and 7, all mounted in a hopper of conventional type 9, closed at the top by flanks 14. These organs are found in all the figures, but are best visible in FIG. 3. From fig. 5 it is understood that there is in fact a pair of guides 11, a pair of jacks 4 and one of jacks 7, as well as a pair of each of the joints. However, for the simplification of the description, we speak of only one of each of these bodies.
  • the invention has this originality, compared to the known technique, that the two thrust and compression elements, 1 and 6, are articulated to each other outside of the guide 11, at 3, while the two jacks 4 and 7 are both attached to the same joint 2 at the upper end of the element 1.
  • the new structure includes the guide or raceway 11, curved in the embodiment shown, but which may be straight; in this guide, at 5, rolls a roller carried by the upper edge of the movable panel 6, which constitutes the upper element of the compression loading means.
  • the flap 1 has a general U-shape: its active part 1 a-1 b, which pushes the materials from the right to the left according to FIGS. 1, 2, 3, 4, 7 and 8, is carried by two arms 1 c and 1 ′ c visible in FIG. 6. These arms rotate around the axis 3 which hinges them on the compression element 6; they also pivot around the axes 2,2 ′, on the guides 11, where the jacks 4 and 7 are attached. This results in an empty space 15 above the axis 3, through which materials can be introduced. in the hopper, regardless of the position of the flap 1.
  • the active part 1 a-1 b of the shutter 1 is preferably of a box construction which allows high forces to be exerted by means of a light weight shutter.
  • the height of the arms 1 c and 1'c is generally about 0.75 to 4 times that of the active part 1 a-1 b, and preferably 1 to 3 times.
  • fig. 8 being a vertical section of the arm 1'c and of the active parts 1 a-1 b, by the plane Z-Z, makes it possible to see both the arm 1'c and the part 1 a-1 b in section (hatched).
  • the bottom of the panel 6 is articulated in 3 to the flap 1, which gives a compound loading assembly, 1 -6, deformable under the action of the associated jacks.
  • the top 5 of the panel 6 is connected to the head 2 of the shutter 1 by a jack 4; the rod 4 'of this jack is articulated at 5 and the cylinder at 2. In this way, as the two ends, 2 and 5, of the jack 4 are located in the path 11, this jack remains always aligned parallel to a tangent to the path 11.
  • a second cylinder, 7, is mounted between the side 14 of the hopper and the head 2 of the flap 1.
  • the end of the cylinder 7 is articulated at 8 on the side of the device, while the rod 7 'of this cylinder is connected to the upper end 2 of the shutter 1, that is to say at the same point where the bottom of the cylinder of the first jack 4 is articulated.
  • the assembly thus formed of flap 1, panel 6, and jack 4, constitutes a triangle, deformable under the action of jack 4, for each of the positions determined by jack 3, when the latter immobilizes the joint 2.
  • the jacks are preferably hydraulic for a device on a vehicle, but can be electric, especially in a fixed installation.
  • the preferred profile of the flap 1 is substantially a triangle with an obtuse angle at the top 3, and an acute angle at the lower end 12.
  • the obtuse angle is preferably about 100 to 125 °, while that of the end 12 measures 10 to 35 °.
  • the elements 1 and 6 occupy their highest place on the raceway or guide 11, that is to say that the rollers of the joints 2 and 5 respectively are in their highest positions.
  • the jacks 4 and 7 are completely retracted, which means that the flap 1 and the panel 6 are aligned along the guide 11, one in the extension of the other; the angle between 1 and 6 is here the smallest of all that these elements can make between them during work.
  • the situation according to fig. 1 is the start of the first stage of the operating cycle. This time lies in the expansion of the pressing cylinder 7 which pushes the joint 2 down the shirt 11. This results in the displacement of the assembly 1-4-6 backwards and downwards, as indicated in the arrow starting from the end 12 in FIG. 1.
  • the first step of the cycle consists in passing the assembly 1-4-6 in the position of fig. 2, that is to say until the end 12 of the shutter 1 arrives at the bottom of the hopper 9.
  • the inlet of the receptacle 13 is closed by the panel 6 and the shutter 1 , as shown in fig. 2.
  • due to the special shape of the shutter 1, described above there remains a free passage 15 between the axis 2 and the active part 1a-1b of the shutter 1.
  • the presence of the free space 15 is an originality of the invention; it brings the advantage of being able to continue loading the hopper even during the stage of FIG. 2, which - in the devices of the known technique - corresponds to the charging stop.
  • the second stage of the operating cycle is the transition from the situation according to fig. 2 to that of FIG. 3.
  • the rod 7 'of the jack 7 being fully extended, it is left in this state, to maintain the joint 2 in place of FIG. 2.
  • Actuate the actuator 4, the rod 4 'of which then pushes upwards the articulation 5, which drives upwards the upper edge of the panel 6.
  • the triangle 1 -4-6 is in the process of deformation and produces the work of loading the materials from the hopper 9 into the receptacle 13: the shutter 1 pivots around the joint 2 in the direction of the needles a watch along the path indicated by an arrow drawn near the bottom of the hopper 9 (fig.
  • the third stage of the cycle begins from the moment when the elements of the device have reached the position of FIG. 3.
  • the rod 7 'of the jack 7 is then retracted, the jack 4 remaining expanded: the two elements, 1 and 6, are then moved upwards, in the direction of the inlet of the receptacle 13, like the shows the arrow in fig. 3. It is the compression phase which takes place, while the assembly tends towards the position of FIG. 4.
  • the rod 7 ′ of the jack 7 being retracted, the configuration of FIG. 4, or the end of loading with compression.
  • the rod 4 ′ of the jack 4 is retracted, which causes the shutter 1 to pivot around the articulation 2 in the opposite direction to that of the second cycle time; the trajectory of the flap 1 is shown by an arrow in FIG. 4. This is the fourth time in the cycle, returning to the rest and opening position in fig. 1.
  • the jacks 4 and 7 are mounted on the sides of the device, outside the hopper 9.
