Definitions

  • This invention relates to a screening apparatus with a tiltable vibratory screen for screening particulate material, such as by separating coarser from finer parts of gravel, coal, crushed rock and similar particulate material.
  • a mobile screening apparatus which comprises a base frame; an elevating conveyor arranged to convey material from a loading station at or near to a lower end of the conveyor to a discharge station at an upper end of the conveyor; a conveyor carrying frame adjustably mounted on the base frame and arranged so as to be capable of moving the conveyor generally lengthwise relative to the mounting of the carrying frame on the base frame; drive means coupled with the carrying frame for adjusting the position of the conveyor lengthwise relative to the base frame; guide means for guiding the movement of the carrying frame; a sub-frame pivotally adjustably mounted on the base frame via a pivot and carrying a vibratory screen arranged to receive material falling under gravity from the upper end of the conveyor, said sub-frame being adjustable about said pivot in order to adjust the attitude of the screen to suit any particular operating requirements and in which it is able to receive material falling under gravity from the upper end of the conveyor; discharge means for discharging separate screened portions of the material after treatment by the vibratory screen; and a linkage between the sub-frame and the
  • a screening apparatus of the above type will be referred to hereinafter as "a screening apparatus of the type set forth".
  • the present invention is primarily, though not exclusively, concerned with improving a screening apparatus of the type set forth and seeks to provide improved folding of the apparatus when it takes up a transport position.
  • the elevating conveyor is of substantial length, usually extending lengthwise of the apparatus and upwardly away from a hopper feed supply at its lower end.
  • the conveyor elevates the material to be screened to its upper discharge end, from which the material falls under gravity onto an underlying screen deck or "screen box".
  • the screen is carried by a support frame which is pivotally mounted on a fixed part of the chassis or main frame of the apparatus, and this support frame is also pivotally connected to part of the movable support structure of the elevating conveyor.
  • this support frame is also pivotally connected to part of the movable support structure of the elevating conveyor.
  • the overall height of the apparatus (in both its operating and its transport mode) is determined to some extent by the length of the screen deck, and if it should be desired to increase the length of the screen deck substantially for certain customers, this may cause the overall height of the apparatus, in its transport mode, to be higher than may be preferred.
  • a screening apparatus for screening particulate material comprising:
  • the main portion and the end portion (of the elevating conveyor and the conveyor carrying frame) form effectively a unitary structure which can function to elevate material to be screened, and which structure can be adjusted lengthwise simultaneously with adjustment of the angle of inclination of the screen, and with the upper discharge end of the conveyor remaining located at a desired position above a material receiving end of the screen for all adjusted operative positions of the conveyor and screen.
  • the end portion is allowed to pivot downwardly in order to reduce the overall height of the apparatus, and this downward adjustment of the end portion is accompanied by downward pivoting of the screen.
  • this conversion means may comprise a telescopically adjustable strut (preferably ram-operated) extending between a suitable mounting point on the base frame and the sub-frame which carries the screen.
  • the conversion means also includes a support upstanding from the base frame and arranged to engage and then bear the load of the main portion when the apparatus is undergoing conversion to the transport mode, and which therefore readily allows the end portion to pivot downwardly relative to the main portion (under continued operation of the ram driving the adjustment of the strut) in order to reduce the overall height of the apparatus.
  • the apparatus is preferably a mobile apparatus having a wheel set to support at least part of the dead load of the apparatus, and the loading end of the apparatus may be designed so as to be capable of being mounted on a "fifth wheel” or other type of coupling of a tractor vehicle.
  • a foldable "tail conveyor” may be arranged below the screen, and which can be pivoted between an operative position in which screened material passing through the screen can be discharged from the apparatus, and to a transport position in which relative folding of separate components of the tail conveyor take place whereby the overall length of the apparatus is reduced. This folding between the transport and operative positions is permitted by reason of the geometry of the tail conveyor sections and their relationship to the mounting of the screen, sub-frame, elevating conveyor and conveyor carrying frame.
  • a screening apparatus is designated generally by reference 10 and comprises a wheel-supported base frame 11, an elevating conveyor 12 comprising an endless belt 28 which is arranged to convey material from a loading station at or near to a lower end of the conveyor to a discharge station at an upper end of the conveyor, and a conveyor carrying frame 13 adjustably mounted on the base frame 11 and arranged so as to be capable of moving the conveyor 12 generally lengthwise relative to the mounting of the carrying frame 13 on the base frame 11.
  • the belt 28 is taken around upper and lower return end drums to follow its required endless path, of which only upper drum 29 is clearly visible in the drawings.
  • the loading station in the illustrated embodiment, comprises a hopper 14, into which material to be screened can be loaded, and the base 15 of the hopper 14 is designed so as to be capable of being mounted on a "fifth wheel coupling" of a tractor vehicle when the apparatus has been converted to the transport mode and is to be transported from one site to another.
  • Screen 17 may comprise a "screen box" which is a multi-deck screen.
  • Drive means may be coupled with the conveyor carrying frame 13 to adjust the position of the conveyor 12 lengthwise relative to the base frame 11, and guide means (not shown in detail) is provided at the lower end of the conveyor frame 13 to guide the movement of the frame 13.
  • a sub-frame 18 supports the screen 17, and comprises A-frame support structures 19 arranged one at each side of the screen 17, and each being pivotally mounted on the base frame or chassis of the apparatus via a horizontal pivot 20 carried by an upstanding support structure 21 mounted at the rear end of the base frame 11.
  • Each A-frame structure 19 also has a pivotal connection 22 with the conveyor carrying frame 13, and each A-frame structure 19 can be pivotally adjusted about pivot 20 in order to vary the attitude or inclination of the screen 17 to suit any particular operating requirements, and in which it is able to receive material falling under gravity from the upper discharge end 16 of the conveyor 12.
  • Discharge means (not shown in detail) are provided to discharge separate screened portions of the material after treatment by the vibratory screen 17.
  • a "tail conveyor” structure designated generally by reference 23 is mounted at the rear end of base frame 11, and is shown in Figure 1 in the operative position in which material which passes downwardly through the screen 17 is received by the tail conveyor 23, and can then be rearwardly and upwardly discharged from the apparatus.
  • Figure 1 of the drawings shows the operating components of the apparatus in their operative positions when the apparatus is converted to its operative mode
  • Figure 3 shows, to an enlarged scale, the relationship between the upper discharge end 16 of the conveyor 12, sub-frame 18, screen box 17, and tail conveyor 23.
  • Figures 2 and 4 correspond with Figures 1 and 3 respectively, but show the positions taken-up by the operative components when adjusted to the transport mode of the apparatus.
  • the elevating conveyor 12 and the elevator carrying frame 13 are each divided into two portions, namely a main portion which extends away from the loading station, (designated by references 12a and 13a respectively in these figures), and an upper end portion, designated by references 12b and 13b and which include the upper discharge end 16 of the conveyor 12.
  • the main portion (12a, 13a) and the upper end portion (12b, 13b) are hingedly connected together to allow the apparatus to be converted between an operative mode, as shown in Figure 3, in which the end portion forms a prolongation of the main portion, and a transport mode (shown in Figure 4) in which the height of the discharge end 16 is reduced.
  • sub-frame 18 is effective, when the apparatus is in the operative mode, to permit adjustment of the inclination of the screen 17 in response to lengthwise adjustment of the carrying frame 13, when the main portion and the end portion are held together in the operative position shown in Figure 3, and effectively form a unitary structure which can be lengthwise adjusted.
  • the sub-frame 18 enables downward adjustment of the end portion to be accompanied by downward adjustment of the screen 17.
  • This means also functions to carry out adjustment of the screen box inclination, and comprises a ram or cylinder operated telescopic support 24 which extends between a pivotal connection 25 at its lower end with a fixed part of the chassis and which is pivotally connected at its upper end 26 to any convenient part of the screen 17 in order to support the latter and thereby maintain the main portion and the end portion in the operative position.
  • upper end 26 is pivotally connected to part of the A-frame 19.
  • the tail conveyor 23 is shown in Figures 1 and 3 in an operative position to discharge material which passes through the screen 17, whereas it can be folded to the transport position shown in Figures 2 and 4.
  • the geometry of the tail conveyor 23, screen 17, sub-frame 18, and their relationship to each other allows the various components of the apparatus to be adjusted between operative modes and transport modes without interfering with each other.
  • the main portion (12a, 13a) and the end portion (12b, 13b) are hingedly connected together via a horizontal pivot 27, and adjustment of the length of telescopic support 24 allows the screen box 17 to pivot about pivot 20, and the end portion (12b, 13b) to pivot about horizontal pivot 27 i.e. the main portion and the end portion no longer form a unitary structure which can be lengthwise adjusted as a unit.
  • the lowering of the screen box 17 is accompanied by downward adjustment of the overall conveyor 12 and carrying frame 13, which reduces the overall height of the apparatus, and as this proceeds, the main portion (12a, 13a) comes into abutment with an upward supporting structure (not shown in Figures 1 to 4, but see Figures 7 and 8 and as described later) and which then allows the end portion (12b, 13b) to "break-open" the hinged connection whereby end portion (12b, 13b) then opens-up the hinge as shown in Figure 4.
  • an upward supporting structure not shown in Figures 1 to 4, but see Figures 7 and 8 and as described later
  • the apparatus can be readily converted to a transport mode in which the overall height of the apparatus is reduced to preferred levels suitable for transport of the apparatus as a towed vehicle along the public highway, and without risk of being obstructed by normal highway bridges.
  • Telescopic support 24 may comprise a hydraulically or pneumatically adjustable ram type structure, or may comprise a manually adjustable support.
  • the effective length of support 24 will be varied during each adjustment of the angle of inclination of the screen 17 when the apparatus is in the operative mode shown in Figures 1 and 3, and also will have its effective length adjusted to follow, or to permit adjustment of the screen 17, sub-frame 18 and end portion 12b, 13b to the transport mode.
  • support 24 may be used both to convert the screening plant between operative and transport modes, but also to adjust the inclination of the screen box to different required positions in the operative mode (which will be accompanied by suitable adjusting movement of the upper discharge end of the elevator).
  • the telescopically adjustable support 24 may comprise the sole means to adjust the inclination of the screen box 17, accompanied by generally longitudinal adjustment of the elevating conveyor 12 and its supporting frame 13 to maintain the upper discharge end of the elevator near the upper end of the screen box for all of its inclinations, when in the operative mode.
  • the support 24 also serves to convert the apparatus to the transport mode, by pulling the elevator frame and simultaneously lowering its upper end until such time as the main portion 12a, 13a of the elevator and the carrying frame have their further downward motion arrested by the abutment, as described above, which then allows the hinge at pivot 27 to "break open".
  • a separate drive means may be provided (not shown) at the lower end of the elevator i.e. at the loading station, to effect necessary generally linear movement of the elevator and the carrying frame.
  • telescopic support 124 is in two parts, comprising a telescopic arrangement of tubes 129 and a hydraulically operated cylinder 130 operative to extend or contract the overall length of the telescopic tube assembly 129.
  • the lower end of the support leg arrangement 124 is pivoted on common pivot 25, which also mounts the folding tail conveyor 23, and the upper end 131 of leg arrangement 124 is pivoted to one arm of the A-frame support structure 19 which carries the screen box 17, and which is pivoted at 22 to the upper end of the separate end portion 13b of the carrying frame 13 for the elevator 12.
  • Figure 5 shows the elevator and screen box in one adjusted position which it can adopt, in an operative mode
  • Figure 6 shows the components in the positions taken-up after conversion to the transport mode.
  • resilient connections are provided between separate panels which make-up the assembly of the endless conveyor belt forming elevator 12, to permit the main elevator portion 12a and end portion 12b to partly hinge open as shown in Figure 6 to take-up the transport mode.
  • a spring assembly may also be provided, which works in conjunction with the conveyor pivot 27, and to allow relative pivotal movement to take place during adjustment between the transport mode and the operative mode.
  • the lower end of the sloping part of the base frame 11, adjacent to the loading hopper 14, is provided with guide means 125, which guides the generally lengthwise movement of the elevator 12 and carrying frame 13 which, as described above, is generally lengthwise movement, but also involves a small mount of upward and downward generally pivotal movement about the lower end of the elevator / carrying frame, in that every time lengthwise adjustment of the elevator takes place, this is accompanied by pivotal adjustment of the screen box 17 about pivot 20, and via the pivot connection 22 between the A-frame support 19, a small amount of upward or downward pivoting of the elevator / carrying frame also takes place.
  • the guide means 125 is capable of accommodating this combined lengthwise / pivotal movement.
  • the telescopic support leg 24 (preferably arranged one at each side and each connected to a respective sub-frame 19), will be effectively retracted which initially causes an upward pulling movement along the length of the elevator / carrying frame, as the screen box 17 pivots clockwise about pivots 20, and this causes a small degree of clockwise pivoting of the elevator / carrying frame assembly about the lower end, so that a lower part 128 (see Figure 7) of the carrying frame 13 progressively approaches a fixed abutment 127.
  • Abutment 127 is shown mounted on a housing structure 126 (housing any required operating components of the apparatus), and Figure 7 shows the carrying frame 13 occupying a position in which the apparatus is still capable of working in any desired one of its operating modes, whereas Figure 8 shows downward adjustment until such time as frame part 128 engages abutment 127.
  • the abutment 127 therefore then bears the load of the main portion 12a of the elevator and main portion 13a of the carrying frame, whereby further adjustment of the support leg assemblies 124 in a retracting sense then causes the "hinge" to break open, and for the end portions 12b, 13b of the elevator and carrying frame to pivot clockwise, thereby lowering the overall height of the apparatus by lowering the discharge end of the elevator, and which is also accompanied by simultaneous downward pivoting of the screen box 17 also to take-up a transport position.
  • the tail conveyor 23 is mounted on the frame of the apparatus so that it can readily be adjusted between the operative position, shown in Figure 5, in which the two conveyor portions 132, 133 form a unitary straight line structure, and the transport position in which conveyor portion 133 is folded to an upright position, thereby to reduce the overall length of the apparatus.
  • Conveyor portions 132 and 133 are pivotally connected together, and conveyor portion 132 is pivotally mounted on a support structure 134 upstanding from the base frame 11, whereas conveyor portion 133 has a lever arm connection 135 by which it is pivotally connected to a support strut 136 which is pivoted to the base frame 11 on the same pivot 25 on which telescopic leg 124 is pivotally mounted.
  • Strut 136 supports the tail conveyor 23, when it is in the operative position shown in Figure 5, but assists in the manipulation of the conveyor portions 132 and 133, via lever arm 135 and the general geometry of the four bar type linkage incorporated in the tail conveyor assembly, whereby to incline conveyor portion 132 downwardly, as shown in Figure 6, and to pivot conveyor portion 133 upwardly to the transport position.
