A mobile, road -hauled aggregate material processing plant comprises a wheel
mounted chassis (2); a plant support frame mounted on the plant support frame; a raw
material input hopper mounted on the plant support frame; a material processing means
mounted on the plant support frame and fed from the input hopper and having an outlet;
processed material outfeed delivery means mounted on the plant support frame and fed
from the material processing means, said outfeed delivery means comprising a lateral
conveyor (4) having a conveyor frame, a plurality of rollers (6,6',6'',6''') mounted on the conveyor frame,
and an endless conveyor belt mounted on the rollers, said belt defining a conveyor plane;
and articulation means for movement of the lateral conveyor (4) from an operative position

operating position in which the conveyor (4) extends laterally from the chassis and an
intermediate position in which the lateral conveyor (4) extends substantially upright from the
chassis and in which rotation of the turntable (20) causes the lateral conveyor (4) to be pivoted
from the intermediate position to a transport position in which it extends along the length
of and above the chassis.
Description
The present invention relates to mobile, road -hauled aggregate material processing plant
such as a screening plant, crushing plant or mining plant of the type which includes a lateral
conveyor which may be moved between a transport position, in which the lateral conveyor
is within the lateral and vertical dimensions which are specified for vehicles which are to
travel on the road, and an operating position in which the lateral conveyor extends laterally
from the plant.
European Patent No 0 641 607 in the name of Rafferty describes and claims a mobile, road
-hauled aggregate material processing plant comprising: a wheel mounted chassis; a plant
support frame mounted on the plant support frame; a raw material input hopper mounted on
the plant support frame; a material processing means mounted on the plant support frame and
fed from the input hopper and having an outlet; processed material outfeed delivery means
mounted on the plant support frame and fed from the material processing means, said outfeed
delivery means comprising a lateral conveyor having a conveyor frame, a plurality of rollers
mounted on the conveyor frame, and an endless conveyor belt mounted on the rollers, said
belt defining a conveyor plane; and articulation means for movement of the lateral conveyor
from an operative position extending laterally of the chassis to a transport position;
characterised in that, said lateral conveyor comprises a tail section and a head section; and
said articulation means comprises: a tail articulation means allowing movement of at least
part of the tail section relative to the plant support frame from the operative positibn to the
transport position, and at the transport position, it extends substantially upright above the
chassis and with respect to the input hopper and the material processing means so that it does
not extend laterally beyond the chassis; and a head articulation means connecting the head
and tail sections to allow movement of the head section relative to the tail section from the
operative position to the transport position, and at the transport position the head section
extends longitudinally above the chassis and with respect to the input hopper and material
processing means so that it does not extend laterally beyond the chassis.
It is a disadvantage of the mobile, road -hauled aggregate material processing plant
described and claimed in European Patent No 0 641 607 that the pivot joint for
articulation of the tail section of the lateral conveyor relative to the head section thereof
is located outboard of the processing plant when the lateral conveyor is in the operating
position. In a preferred embodiment of the mobile, road -hauled aggregate material
processing plant described and claimed in European Patent No 0 641 607, the drive means
for the articulated tail section comprises a hydraulic ram drive means mounted between
the tail and head sections, and it is a further disadvantage that this hydraulic ram drive
means is also located outboard of the processing plant when the lateral conveyor is in the
operating position. The outboard location of the pivot joint and the hydraulic drive means
in the operating position of the lateral conveyor are particularly disadvantageous because
of the hostile and difficult environmental conditions under which the plant is operated.
It is a further disadvantage of the outboard location of the pivot joint that the lateral
conveyor cannot be mechanically locked relative to the plant in its operating position.
It is an object of the present invention to provide a mobile, road -hauled aggregate
material processing plant in which the above disadvantages are reduced or substantially
obviated.
The present invention provides a mobile, road -hauled aggregate material processing plant
comprising: a wheel mounted chassis; a plant support frame mounted on the plant support
frame; a raw material input hopper mounted on the plant support frame; a material
processing means mounted on the plant support frame and fed from the input hopper and
having an outlet; processed material outfeed delivery means mounted on the plant support
frame and fed from the material processing means, said outfeed delivery means
comprising a lateral conveyor having a conveyor frame, a plurality of rollers mounted on
the conveyor frame, and an endless conveyor belt mounted on the rollers, said belt
defining a conveyor plane; and articulation means for movement of the lateral conveyor
from an operative position extending laterally of the chassis to a transport position
characterised in that the articulation means is mounted on the chassis and comprises a
vertically mounted turntable, upon which turntable one end of the lateral conveyor is
pivotably mounted so that the lateral conveyor is pivotable relative to the turntable
between an operating position in which the conveyor extends laterally from the chassis
and an intermediate position in which the lateral conveyor extends substantially upright
from the chassis and in which rotation of the turntable causes the lateral conveyor to be
pivoted from the intermediate position to a transport position in which it extends along
the length of and above the chassis.
In a preferred embodiment of the mobile, road -hauled aggregate material processing
plant according to the invention, the vertically mounted turntable is provided with
mechanical locking means operative to lock the lateral conveyor in the operating position.
The mobile, road -hauled aggregate material processing plant according to the invention
is preferably provided with two lateral conveyors, each of which extends from the chassis
of the plant, the first from the right hand side and the second from the left hand side.
An embodiment of a mobile, road -hauled aggregate material processing plant will now
be described with reference to the accompanying drawings in which
A mobile, road -hauled aggregate material processing plant shown generally at 10 in
Figure 1 comprises a chassis 2 on which is pivotably mounted a lateral conveyor 4. The
lateral conveyor 4 comprises a plurality of conveyor rollers 6, 6', 6", 6"' mounted for
rotation on a frame 8. A flexible conveyor belt (not shown) for conveying aggregate
material can be located in known manner on the lateral conveyor 4. The conveyor 4 is
mounted on a vertical turntable 20 mounted on the chassis 2 and rotation of the vertical
turntable 20 drives the lateral conveyor from a first transport position as shown in solid
lines to a second intermediate position as shown in shadow in Figure 1. A hydraulic ram
14 is mounted on the chassis 2 to drive the lateral conveyor 4 between the transport
position and the intermediate position.
Figure 2 is a rear view of the processing plant of Figure 1 showing the lateral conveyor 4,
in solid lines, in the operating position and in shadow in the intermediate position. A pair
of hydraulic rams 16 are mounted on the chassis 2 to drive the lateral conveyor 4 between
the intermediate and the travel position, about a pivot point 12 fixed on the vertical
turntable 20.
The vertically mounted turntable 20 is shown in more detail in Figures 3 and 4. A
turntable shown generally at 20 is mounted on the chassis 2 of the processing plant 10.
The turntable 20 is secured on the chassis 2 by means of a headed pin 18 terminating in a
threaded portion 22 adapted to receive a nut 24 and washer 26. The pin 18 comprises a
first head portion 28, a first intermediate portion 30, a second intermediate portion 32 and
the threaded portion 22. At the transitions between the first intermediate portion 30 and
the second intermediate portion 32 and the second intermediate portion 32 and the
threaded portion 22 respectively, shoulders 34, 36 are formed. A through aperture 38,
sized to receive the second intermediate portion 32 of the pin 18 is provided in the chassis
2.
The turntable 20 comprises a rotating face 40 and two pairs of support plates 42,44
mounted on the rotating face 40 and at right angles thereto. A through aperture 46, sized
to receive the first intermediate portion 30 of the pin 18 is provided in the rotating face
40.
The support plates 42,44 are spaced apart in pairs and each pair is linked at pivot point 12
and pivot point 48 by means of rods 50,52. The two sides of the conveyor frame 8 engage
the rods 50 and the two hydraulic rams 16 engage the rods 52.
A flat plate 54 is mounted on the lower edge faces 56 of the support plates 42 and 44, to
provide additional strength and itself supports two spaced L-shaped brackets 58. A rod 60
links the L-shaped brackets 58 and provides an engagement point for the hydraulic ram
14.
A mechanical hook 62 is provided on the chassis 2, and provides a recess 64 in which the
rotating face 40 of the turntable 20 can be received, thus providing a mechanical lock
ensuring that the face 40 is locked in the vertical plane.
To secure the turntable 20 to the chassis 2, the pin 18 is inserted through the through
apertures 38 and 46 and the nut 24 and associated washer 26 are located on the pin 18 and
tightened until the shoulders 34 engage the rotating face 40 of the turntable 20.
In operation, and starting from the transport position as shown in solid lines in Figure 1,
the vertical turntable 20 is driven in rotation in an anti clockwise direction by the
hydraulic ram 14 until the lateral conveyor is in a position in which it extends
substantially vertically upwards from the chassis, i.e. the intermediate position as shown
in shadow in Figures 1 and 2.
The next stage of the operation can be seen more clearly from Figure 2. The lateral
conveyor 4 is lowered from the intermediate position to the operating position by means
of the pair of hydraulic rams 16.
The above operation is carried out in reverse in order to move the conveyor from the
operating to the transport position.
As can be seen more clearly from Figure 2, the processing plant 10 comprises a second
lateral conveyor 4' extending from the opposite side of the chassis 2.
The second conveyor 4' is longitudinally offset relative to the first conveyor 4 along the
length of the vehicle.
The second conveyor 4' is similar to the first conveyor 4, but is mounted and rotates in the
opposite hand to the first conveyor 4.
