Abstract
An asymmetrical chute (10) for particulate material is generally trough shaped with a form which changes over the length of the chute and includes two substantially planar sections (16 and 17) connected together along joint (19), with section (17) substantially vertical, whilst section (16) forms a base section, and a curved section (15) connected to the base section (16). <IMAGE>
Description
SPECIFICATION
Chutes for particulate material
This invention relates to chutes for particulate
material.
In particular, although not exclusively, the
present invention relates to chutes for delivering particulate material, for example, broken coal, fed from a discharge conveyor on to a receiving
conveyor, the two conveyors being arranged transverse to each other.
An object of the present invention is to provide
an improved chute for delivering particulate
material on to a receiving conveyor, the material being delivered over a substantial width of the receiving conveyor.
According to the present invention a chute for delivering particulate material fed from a discharge conveyor comprises a generally downwardly inclined guide component defining a substantially inverted trough shaped working surface for guiding particulate material, at least a portion of the guide component having a working surface cross-section comprising two transversely arranged, substantially linear sections and a curved section.
Preferably, the curved section is connected to the adjacent linear section substantially mid-way across the width of the chute.
Preferably, a further portion of the guide component has a solely curved cross-section.
Advantageously, the solely curved crosssection constitutes the discharge portion of the chute.
By way of example, two embodiments of the present invention will be described with reference to the accompanying drawings, in which: Figure 1 is a diagrammatic view of a prior known chute;
Figure 2 is a diagrammatic view of a chute constructed in accordance with one embodiment of the present invention;
Figure 3 is a diagrammatic view of a chute constructed in accordance with a second embodiment of the present invention;
Figure 4 is a diagrammatic plan of Figure 3;
Figure 5 is a diagrammatic side view of Figure 3;
Figure 6 is an incomplete longitudinal sectional view substantially taken along line VI--VI of
Figure 3;
Figure 7 is an incomplete cross-section taken along line VIl-VIl of Figure 5; and
Figure 8 is an incomplete cross-section taken along line VIll-VIll of Figure 5.
Figure 1 shows a diagrammatic end view of a prior known chute 1 installed to receive particulate material, for example coal, from a discharge conveyor 2 (only the discharge end of which is shown) and to deliver the received material on to a receiving conveyor (not shown). The chute comprises a generally downwardly inclined guide component 3 defining a substantially inverted trough shaped working surface 4 for guiding the received particulate material. As indicated in the .drawing the guide component has a solely curved
working surface cross-section which is
symmetrical about the centre line 5 of the guide
component.
As indicated in Figure 1 the prior known chutes suffer from the disadvantage that the flow path 6
material discharging from the chute is not evenly distributed across the width of the discharge
portion of the working surface but instead tends to
be restricted to one side of the centre line. Thus, with the prior known chute material tends to be
loaded only on one side of the receiving conveyor
leading to spillage, inefficient loading of the conveyor and general out of alignment problems.
Figure 2 shows a diagrammatic end view of a chute 10 constructed in accordance with a first embodiment of the present invention and installed to receive particulate material, for example, coal, fed from a discharge conveyor 11 (only the discharge end of which is shown) and to deliver received material on to a receiving conveyor (not shown). The chute comprises a generally downwardly inclined guide component 12 defining a substantially inverted trough shaped working surface 13 for guiding the received particulate material. As indicated in the drawing the guide component has an asymmetrical form about its centre line 14.The right hand side of the guide component as viewed in Figure 2 is constituted by a curved section 1 5. The left hand side of the guide component as viewed in Figure 2 is constituted by two transverse, substantially linear sections 1 6 and 1 7 connected to each other along joint 1 9 so that the section 1 6 constitutes a part of the base of the trough shaped working surface and the section 1 7 constitutes one substantially vertical limb of the trough shaped working surface. In the embodiment shown in
Figure 2 the two linear sections 16, 17 are arranged almost normal to each other looking in the direction of material flow.The curved section 1 5 is joined to the base linear section substantially along the centre line of the guide component.
The two substantially linear sections 16 and 17 extend through the discharge portion of the guide component. However, as seen in the drawing in the lowermost portion of the guide component the substantially linear base section 1 6 diverges and extends up to the extreme left side edge of the discharge portion.
Figure 2 illustrates that with a chute according to the present invention the material flow path 20 substantially extends across the full width of the discharge portion tending to give uniform loading across the full width of the receiving conveyor.
Figures 3 to 8 illustrate diagrammatically a second embodiment of the invention in which the discharge portion of the chute comprises a solely curved section, the outer profile of the curved section substantially following the cross-sectional form of the receiving conveyor 30. In other respects the chute is similar to that illustrated in
Figure 2 and the same reference numerals have been used for similar items of equipment.
Figures 3 to 8 show the second embodiment of chute 10 installed to receive particulate material, as for example, coal, fed from a discharge conveyor 11 (on a part of the discharge end of which is shown) and to deliver received material on to the receiving conveyor 30. The chute comprises a generally downwardly inclined guide component 12 defining a substantially inverted trough shaped working surface 13 for guiding the received particulate material. As seen in the drawings the guide component is asymmetrical about its centre line 14. The right hand side of the guide component as viewed in Figure 3 is constituted by a curved section.A relatively upper portion of the left hand side of the guide component as seen in Figure 3 is constituted by two transversely arranged, substantially linear sections 1 6 and 1 7 connected together along edge 1 8 so that this portion of the guide member has a working surface cross-section comprising two transversely arranged, substantially linear sections 16 and 17 and a curved section 15.
Figure 7 illustrates the cross-sectional profile at the relatively upper portion with the curved section connected to the base linear section substantially along the centre line of the guide component.
The relatively low discharge portion of the guide component comprises a solely curved section 21 as indicated by Figure 8. The curved discharge section enables the lowermost profile of the guide component to follow closely the curved uppermost profile of the receiving conveyor.
Although the material flow path is not shown in
Figure 3 to 8 it will in practice be similar to the flow path 20 shown in Figure 2.
