Description
CONTROL APPARATUS FOR CONVEYOR OF PARTICULATE MATERIAL
Field of the Invention The present invention relates to a mount for a device which attaches to a conveyor belt to control the conveyance of particulate matter along the belt.
Background of the Invention Conveyors for moving or projecting particulate material such as stone, sand or gravel can be found in various applications. One particular application where conveyors are used to move particulate material is a vehicle known as a stone spreader. Stone spreaders are used to project particulate material to a desired location remote from the vehicle determined by the orientation and speed of the conveyor.
A shield assembly for a stone spreader facilitates the control of the particulate material at various conveyor belt speeds or for high elevation applications. The shield assembly enables the particulate material to be thrown a distance beyond the end of the conveyor which is dependant on the speed of the conveyor and the control offered by the use of the shield assembly. The shield assembly can increase the throwing distance of particular material to over four times over the traditional conveyor.

FIG. 1 is a partial side view of a shield assembly mounted in position above a conveyor belt assembly;
3 FIG. 2 is an enlarged partial view of Figure 1 showing the mount in accordance with the present invention;
FIG. 3 is a sectional assembly view of the mount according to the present invention;
Description of the Preferred Embodiments Referring to Figure 1, a side view of conveyor belt assembly 13 is shown in vertical spaced apart relationship to a shield assembly 11 mounted above the conveyor belt 12 according to the present invention. The conveyor belt 12 receives particulate matter from the stone spreader vehicle for conveyance to a designated job location and is pivotally attached to the stone spreader by means of frame 50.
The stone spreader includes a drive means (not shown) to power the conveyor belt 12 so as to move particulate material (not shown) deposited onto the conveyor belt 12 from the stone spreader bed or from a hopper.

The shield assembly 11 is comprised of a powered or unpowered endless belt 16 having a length and width. The endless belt 16 is mounted on wheels 22 or axles 24 attached between two longitudinal frame elements 20 one of which is shown. The frame elements 20 are provided with holes for receiving the ends of the axles 24. The axles 24 are rotatably secured within sealed bearing assemblies
4 33 mounted on the outside of the frame elements 20. The externally mounted sealed bearing assemblies 33 allow for the application of grease without disassembly of the shield assembly 11.
In a preferred embodiment, the shield assembly 11 includes a plurality of pairs of wheels 22 or axles 24 positioned along the length of the frame element 20 at suitable intervals so as to provide adequate support therefor. The number of wheels 22 and axles 24 between the ends of the belt 16 will vary depending on the size of the endless belt 16.
In an embodiment of the present invention, the motion of the conveyor belt 12 drives the endless belt 16 as a result of the frictional engagement between the belts 12 and 16. The frictional engagement may result from direct contact between the belts 12 and 16 or indirect contact, where the particulate material that is passing between the belts 12 and 16 transfers the motion from the conveyor belt 12 to the endless belt 16. In an alternative embodiment of the present invention a hydraulic motor is used to power the belt 16 independent of any frictional engagement between belts 16 and 12. The hydraulic motor (not shown) is installed on the frame elements 20 and drives a sprocket wheel which is operatively engaged with the underside of the endless belt 16.
The shield assembly 11 is operationally mounted above the conveyor belt 12 between a pair of mounts one of which is shown in Figures 2 and 3. Each mount comprises two mounting brackets 31 attached to the frame 50. The mounting brackets 31 support the shield assembly 11 therebetween by means of linkages 30 pivotally attached to the mounting brackets 31 and frame elements by means of bearing assemblies 33. The brackets 31 have hole attachment means to accommodate for the attachment to the frame 50 and the pivoting linkages 30 as described. The central portion 37 of the mounting brackets 31 may

The shield assembly 11 is operationally mounted above the conveyor belt 12 between a pair of mounts one of which is shown in Figures 2 and 3. Each mount comprises two mounting brackets 31 attached to the frame 50. The mounting brackets 31 support the shield assembly 11 therebetween by means of linkages 30 pivotally attached to the mounting brackets 31 and frame elements by means of bearing assemblies 33. The brackets 31 have hole attachment means to accommodate for the attachment to the frame 50 and the pivoting linkages 30 as described. The central portion 37 of the mounting brackets 31 may
5 be outwardly or inwardly bent as required to allow the top portion of the bracket 31 and linkage assemblies to accommodate and clear the frame 50 of the conveyor to avoid interference with the conveyor belt 12 and the shield assembly 11.
Depending on the conveyor belt assembly 13 installed on a stone spreader vehicle, the height and width of the brackets 31 may be easily and selectively varied so that the mount according to this invention is in fact universal and suitable for all stone spreader applications.
A connecting rod 32 extends between the frame elements 20 to provide stiffness and support. As shown in Figure 3, the connecting rod 32 may consist of four rod segments 35 extending between the second ends of the pivoting linkages 30 releasably secured together by two bolted connections 36. The bolted connections 36 allow for the disassembly of the connecting rod 32 for bearing replacement.
The mount assembly controls vertical movement of the shield assembly 11 and allows for up and down vertical movement of the shield assembly 11 when particulate material passes between the belts 12 and 16. The maximum vertical deflection of the shield assembly 11 is limited by the vertical range of the pivoting linkage. The mount also allows for front to back tilting and raising as required. The

6 mount prevents side-to-side rocking of the shield assembly 11 by enabling that the vertical deflection of the shield assembly 11 to be equal across the width of belt 16.
It will be apparent to those skilled in the art that the apparatus of the invention can be utilized with any conveyor and with a variety of material.
For example, particulate material may include sand, gravel, salt, rock etc. The conveyor assembly may be associated with trucks (as described above) or with mining, equipment, farming equipment etc.
Although the invention has been described with reference to certain specific embodiments, various modifications thereof will be apparent to those skilled in the art without departing from the spirit and scope of the invention as outlined in the claims appended hereto.
