Abstract
The present invention is directed to an apparatus for creating a stockpile of bulk material, comprising a conveyor having a feed end and a distribution end; a stabilizer at the feed end of the conveyor; and a support at the distribution end of the conveyor; wherein the support includes a primary hydraulic cylinder having a base portion connected to the support and an end portion which extends and retracts longitudinally to alter the angle between the conveyor and the ground; and a secondary hydraulic cylinder having one end connected to the support and the other end connected to the primary hydraulic cylinder, where the secondary hydraulic cylinder extends and retracts in a lateral direction, thus pivoting the primary hydraulic cylinder against the support. This design is simpler and less expensive than a conveyor with an undercarriage and makes for a smaller staging area as room for the undercarriage is unnecessary.
Description
CARRIAGELESS STOCKPILING CONVEYOR
FIELD OF THE INVENTION
The present invention relates to equipment for stockpiling bulk material;
specifically, a cost-effective apparatus that is able to "climb" the stockpile as it is being formed.
BACKGROUND OF THE INVENTION
A stockpile is a pile or storage location for bulk materials, forming part of the bulk material handling process. The stockpile is normally created by a stockpiling conveyor (or stacker).
Stockpiles are normally stacked in stockyards in refineries, ports and mine sites.
As can be seen in Figure 1, a traditional stockpiling conveyor (10) utilizes an undercarriage frame (12) or fixed structural supports having an extendable support (14) to raise the conveyor to desired height and lay the stockpile (16) below.
Stockpiling conveyors can also travel on a rail between stockpiles in the stockyard. This allows it to typically move in at least two directions: horizontally along the rail and vertically by luffing (raising and lowering) its boom. Luffing of the boom minimises dust by reducing the distance that material such as coal needs to fall to the top of the stockpile. The boom is luffed upwards as the height of the stockpile increases. Some stockpiling conveyors can rotate the boom. This allows a single stockpiling conveyor to form two stockpiles, one on either side of the conveyor.
U.S. Patent No. 6,126,738 an inclined conveyor is shown that may be inclined at a climb angle B of about 22 degrees with respect to the ground. The inclined conveyor is pivoted on a support at a first end, near the horizontal conveyor. A movable frame with a support tower is provided for support for elevating or inclining the inclined conveyor. The wet mixture is dropped from height to the base surface to form one or more conical piles. In the embodiment the radial stacker is preferably stepped through a horizontal arc to form multiple overlapping piles.
Date Recue/Date Received 2022-09-29 Japanese Patent Application No. JP2010075798A discloses a self-travelling processing machine. The self-traveling machine comprises of a processing unit for processing matters, a discharge conveyor that transports objects and discharges them, a plurality of non-contact type sensors installed in the discharge conveyor. The sensors are used to measure height at each different measuring point of a slope on the same side as the heap. The plurality of sensors help calculate the height and angle of repose and the vertex. The peak position is used to calculate the volume of the processing operation.
There still remains a need for a more cost-effective apparatus, one that is less expensive and more portable. There also remains a need for a stockpiling conveyor which can create large stockpiles within a smaller staging area.
SUMMARY OF THE INVENTION
The present invention features a design with no undercarriage. It utilizes the stockpile of material it has already deposited as a support and climbs (walks) on top of that stockpile to raise itself and deposit more stockpile. In this regard, a hydraulic ram at the distribution end operates in conjunction with the support to jack the support in an incremental ratcheting fashion as the stockpile gets higher.
The present invention is directed to an apparatus for creating a stockpile of bulk material, the apparatus comprising a conveyor portion having a feed end and a distribution end; a stabilizer at the feed end of the conveyor for temporarily fixing the conveyor portion to the ground, creating an angle between the conveyor portion and the ground; and a support at the distribution end of the conveyor portion; wherein the support includes a primary hydraulic cylinder having a base portion connected to the support and an end portion which extends and retracts in a longitudinal direction to alter the angle between the conveyor portion and the ground; and a secondary hydraulic cylinder having one end connected to the support and the other end connected to the primary hydraulic cylinder, where the secondary hydraulic cylinder extends and retracts in a lateral direction, thus pivoting the primary hydraulic cylinder against the support.

4 Date Recue/Date Received 2022-09-29 DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
Figures 2-6 show the stockpiling conveyor apparatus 20 of the present invention. It features a conveyor portion 22 having a feed end 24 and a distribution end 26. Stability at the feed end 24 is provided by a stabilizer 28. This stabilizer 28 can be in the form of a large ground plate or bar, which allows for pivoting and incline movement of the conveyor portion 22, but prevents translation or twisting movement. At the distribution end 26 of the conveyor portion 22 is a support 30, which initially rests upon the ground 50.
As can best be seen in Figure 7, the support 30 includes a primary hydraulic cylinder 32 and a secondary hydraulic cylinder 36. The primary hydraulic cylinder 32 is connected to the support 30 at a base portion 36. An end portion 38 of the primary hydraulic cylinder 32 is able to extend and retract in longitudinal direction A.
The secondary hydraulic cylinder 36 is connected at one end to the support 30, with the other end being connected near the middle of the primary hydraulic cylinder 32.
Therefore, as shown in Figure 7, as the secondary hydraulic cylinder 36 extends and retracts, the primary hydraulic cylinder 32 pivots against the support 30 in direction B.
In use, the stockpiling operation would start with the stockpiling conveyor apparatus 20 in its lowest position, with the support 30 resting against the ground (Figure 2).
The deposition of the material creates a conical stockpile 40 at the distribution end 26 of the conveyor portion 22. As the material stockpile raises up to maximum height under the conveyor apparatus 20, the stockpile 40 starts to bury the support 30 under the material (Figure 3).
The distribution end 26 is then raised in a ratcheting fashion by contracting the primary hydraulic cylinder 32 and then extending it.
During contraction, the primary hydraulic cylinder end portion 38 pulls through the stockpile material, with the support 30 acting against the stockpile.
During subsequent extension, the primary hydraulic cylinder end portion 38 acts against the stockpile material, raising the support 30, thus ratcheting the distribution end 26 higher atop
Figures 2-6 show the stockpiling conveyor apparatus 20 of the present invention. It features a conveyor portion 22 having a feed end 24 and a distribution end 26. Stability at the feed end 24 is provided by a stabilizer 28. This stabilizer 28 can be in the form of a large ground plate or bar, which allows for pivoting and incline movement of the conveyor portion 22, but prevents translation or twisting movement. At the distribution end 26 of the conveyor portion 22 is a support 30, which initially rests upon the ground 50.
As can best be seen in Figure 7, the support 30 includes a primary hydraulic cylinder 32 and a secondary hydraulic cylinder 36. The primary hydraulic cylinder 32 is connected to the support 30 at a base portion 36. An end portion 38 of the primary hydraulic cylinder 32 is able to extend and retract in longitudinal direction A.
The secondary hydraulic cylinder 36 is connected at one end to the support 30, with the other end being connected near the middle of the primary hydraulic cylinder 32.
Therefore, as shown in Figure 7, as the secondary hydraulic cylinder 36 extends and retracts, the primary hydraulic cylinder 32 pivots against the support 30 in direction B.
In use, the stockpiling operation would start with the stockpiling conveyor apparatus 20 in its lowest position, with the support 30 resting against the ground (Figure 2).
The deposition of the material creates a conical stockpile 40 at the distribution end 26 of the conveyor portion 22. As the material stockpile raises up to maximum height under the conveyor apparatus 20, the stockpile 40 starts to bury the support 30 under the material (Figure 3).
The distribution end 26 is then raised in a ratcheting fashion by contracting the primary hydraulic cylinder 32 and then extending it.
During contraction, the primary hydraulic cylinder end portion 38 pulls through the stockpile material, with the support 30 acting against the stockpile.
During subsequent extension, the primary hydraulic cylinder end portion 38 acts against the stockpile material, raising the support 30, thus ratcheting the distribution end 26 higher atop
5 Date Recue/Date Received 2022-09-29 the stockpile 40 it has already created (Figure 4). Figure 7 shows direction A
of the movement of the primary hydraulic cylinder end portion 38. This increases the angle (a) between the conveyor portion 22 and the ground 50, giving the equipment more height to deposit further material above the stockpile 40.
The contraction and extension motion of the primary hydraulic cylinder end portion 38 in direction A are repeated until the angle (a) reaches its maximum (as seen in Figures 5-6). This maximum angle (a) is typically around 18 to 20 , although if a cleated belt is used on the conveyor portion 22, the maximum of the angle (a) could be up to approximately 25 , depending on the type of bulk material.
As shown in Figure 7, once the maximum height of the stockpile 40 is achieved, the secondary hydraulic cylinder 34 extends, pivoting the primary hydraulic cylinder 32 along direction B, thus pushing the distribution end 26 of the conveyor portion laterally. This lateral/translational movement of the distribution end 26 lowers the support 30 down the side of the stockpile 40. As the primary hydraulic cylinder end portion 38 continues to extend and retract in a lateral direction, the conveyor apparatus is able to slowly climb or "step" down the side of the conical stockpile 40.
In one embodiment, the stabilizer 28 at the feed end 24 of the conveyor portion 22 includes elements such as outriggers (not shown), which enable translational movement of the feed end 24 of the conveyor portion 22. The translational movement of the feed end 24, combined with the above-mentioned translational movement of the support 30 at the distribution end 26, allows for the entire stockpiling conveyor apparatus 20 to move in a lateral direction. After repeated operations, this results in a row of stockpile material, rather than a single conical pile.
Figures 8 and 9 show the present invention including multiple optional elements.
In one embodiment, where the conveyor apparatus 20 is foldable for ease of transport, the conveyor portion 22 includes a hinge 60 partway along its length. A locking bolt 62 is engaged during operation of the conveyor apparatus 20, and is removed to allow the conveyor portion 22 to be folded over. An additional locking bolt 62' can be located at the connection
of the movement of the primary hydraulic cylinder end portion 38. This increases the angle (a) between the conveyor portion 22 and the ground 50, giving the equipment more height to deposit further material above the stockpile 40.
The contraction and extension motion of the primary hydraulic cylinder end portion 38 in direction A are repeated until the angle (a) reaches its maximum (as seen in Figures 5-6). This maximum angle (a) is typically around 18 to 20 , although if a cleated belt is used on the conveyor portion 22, the maximum of the angle (a) could be up to approximately 25 , depending on the type of bulk material.
As shown in Figure 7, once the maximum height of the stockpile 40 is achieved, the secondary hydraulic cylinder 34 extends, pivoting the primary hydraulic cylinder 32 along direction B, thus pushing the distribution end 26 of the conveyor portion laterally. This lateral/translational movement of the distribution end 26 lowers the support 30 down the side of the stockpile 40. As the primary hydraulic cylinder end portion 38 continues to extend and retract in a lateral direction, the conveyor apparatus is able to slowly climb or "step" down the side of the conical stockpile 40.
In one embodiment, the stabilizer 28 at the feed end 24 of the conveyor portion 22 includes elements such as outriggers (not shown), which enable translational movement of the feed end 24 of the conveyor portion 22. The translational movement of the feed end 24, combined with the above-mentioned translational movement of the support 30 at the distribution end 26, allows for the entire stockpiling conveyor apparatus 20 to move in a lateral direction. After repeated operations, this results in a row of stockpile material, rather than a single conical pile.
Figures 8 and 9 show the present invention including multiple optional elements.
In one embodiment, where the conveyor apparatus 20 is foldable for ease of transport, the conveyor portion 22 includes a hinge 60 partway along its length. A locking bolt 62 is engaged during operation of the conveyor apparatus 20, and is removed to allow the conveyor portion 22 to be folded over. An additional locking bolt 62' can be located at the connection
6 Date Recue/Date Received 2022-09-29 point of the conveyor portion 22 and the support 30. When the stockpiling conveyor apparatus 20 is not operational, one could remove the locking bolt 62', allowing the support 30 to be pivoted for transport. Figure 9 shows the conveyor apparatus 20 in a folded position with the conveyor portion 22 folded over, and the support 30 pivoted for transport.
Although a locking bolt 62, 62' is shown in the Figures, any type of locking/un-locking mechanism could be used in a similar manner. Once in the folded position, the conveyor apparatus 20 is easily containerized for transport.
Alternatively to containerizing the folded apparatus, the folded apparatus could be towed when in a folded position. As shown in Figure 8, the stockpiling conveyor apparatus 22 may also include a removeable or retractable wheel assembly 64. This wheel assembly 64 would be removed or retracted during operation of the conveyor apparatus 20, but could then be attached or extended, allowing for the apparatus to be towed.
