Abstract

This disclosure is drawn systems, devices, apparatus, and/or methods related to the separation of a mixture of solids according to size and the separation of solids from liquid. Specifically, this disclosure is drawn to an adjustable weight set for use on vibratory separators. In some examples, the adjustable weight set may include a base plate rotatable about an axis and extending radially outward from the axis; a plurality of slots extending through the base plate and being disposed between a radially outward periphery of the base plate and the axis; a plurality of weights coupled to each other about the base plate; and a weight locking tab that partially surrounds the base plate that may include one or more hooks extending through a portion of a slot.

First claim

What is claimed is:

1. An adjustable weight set for a vibratory motor, comprising:
a base plate rotatable about an axis and extending radially outward from the axis, comprising:
a top surface;
a first side;
a second side; and
a bottom surface;

wherein the top surface and the bottom surface of the base plate are in a plane that is substantially perpendicular to the axis;
a plurality of slots extending through the top surface and the bottom surface of the base plate, the slots being disposed between a radially outward periphery of the base plate and the axis;
a plurality of weights coupled to each other, wherein at least a first weight is disposed above the base plate, and wherein at least a second weight is disposed below the base plate; and
a weight locking tab that partially surrounds the base plate comprising:
a top portion extending across the top surface of the base plate; and
a hook coupled to the top portion and extending through at least a portion of a slot;

wherein the weights include flanges positioned radially outward of and contacting at least a portion of the weight locking tab.

2. The adjustable weight set of claim 1 , wherein the weight locking tab further comprises:
a first side portion coupled to the top portion and extending from the top surface of the base plate past the bottom surface of the base plate along the first side of the base plate;
a second side portion coupled to the top portion and extending from the top surface of the base plate past the bottom surface of the base plate along the second side of the base plate;
a first flange coupled to the first side and extending across at least a portion of the bottom surface of the base plate; and
a second flange coupled to the second side and extending across at least a portion of the bottom surface of the base plate;
wherein the hook is smaller than the first side portion and the second side portion and is sized such that, when the weight locking tab is lifted, the hook rises out of the slot.

3. The adjustable weight set of claim 1 , wherein the slots are arranged linearly and are equally spaced from each other.

4. The adjustable weight set of claim 1 , further comprising:
a plurality of lateral pairs of slots extending through the top surface and the bottom surface of the base plate;
wherein the lateral pairs of slots are disposed between a radially outward periphery of the base plate and the axis;
wherein the lateral pairs of slots are arranged linearly and are equally spaced from each other; and
wherein the weight locking tab includes a pair of hooks coupled to the top portion, and each hook of the pair of hooks extends through at least a portion of a slot.

5. The adjustable weight set of claim 1 , wherein the weights are U-shaped and have arms, and wherein the arms of the U-shape extend toward the axis.

6. The adjustable weight set of claim 1 , further comprising:
a plurality of lateral pairs of slots extending through the top surface and the bottom surface of the base plate;
wherein the lateral pairs of slots are disposed between a radially outward periphery of the base plate and the axis;
wherein the lateral pairs of slots are arranged linearly and are equally spaced from each other;
wherein the weight locking tab further comprises:
a first side portion coupled to the top portion and extending from the top surface of the base plate past the bottom surface of the base plate along the first side of the base plate;
a second side portion coupled to the top portion and extending from the top surface of the base plate past the bottom surface of the base plate along the second side of the base plate;
a first flange coupled to the first side and extending across at least a portion of the bottom surface of the base plate; and
a second flange coupled to the second side and extending across at least a portion of the bottom surface of the base plate;

wherein the weight locking tab includes a pair of hooks coupled to the top portion, and each hook of the pair of hooks extends through at least a portion of a slot;
wherein the hooks are smaller than the first side portion and the second side portion and are sized such that, when the weight locking tab is lifted, the hooks rise out of the slots; and
wherein the weights are U-shaped and have arms, and wherein the arms of the U-shape extend toward the axis.

7. A vibratory motor for use in a vibratory separator, comprising:
a motor;
a lower weight set operatively coupled to a lower end of the motor; and
an upper weight set operatively coupled to an upper end of the motor, the upper weight set comprising:
a base plate rotatable about an axis and extending radially outward from the axis;
a plurality of slots extending through the base plate between the axis and a periphery of the base plate;
a plurality of weights coupled to each other about the base plate; and
a weight locking tab that partially surrounds the base plate comprising one or more hooks, wherein each hook extends through at least a portion of a slot.

8. The vibratory motor of claim 7 , wherein the at least one hook is sized such that, when the weight locking tab is lifted, the hook completely rises out of the slot.

9. The vibratory motor of claim 7 , wherein the slots are equally spaced from each other and are disposed linearly between the axis and the periphery of the base plate.

10. The vibratory motor of claim 7 ,
wherein the slots are arranged as lateral pairs of slots disposed linearly between the axis and the periphery of the base plate;
wherein the lateral pairs of slots are equally spaced from each other; and
wherein the weight locking tab includes a pair of hooks, each hook being sized and spaced to extend through at least a portion of a slot.

11. The vibratory motor of claim 7 , wherein the weights are U-shaped and have arms, and wherein the arms of the U-shape extend toward the axis.

12. The vibratory motor of claim 7 ,
wherein the slots are arranged as lateral pairs of slots disposed linearly between the axis and the periphery of the base plate;
wherein the lateral pairs of slots are equally spaced from each other;
wherein the weight locking tab includes a pair of hooks, each hook being sized and spaced to extend through at least a portion of a slot;
wherein the hooks are sized such that, when the weight locking tab is lifted, the hooks completely rise out of the slots; and
wherein the weights are U-shaped and have arms, and wherein the arms of the U-shape extend toward the axis.

13. A vibratory separator, comprising:
one or more separator frames;
one or more separator screens positioned between the one or more separator frames; and
a vibratory motor operatively coupled to the one or more separator frames and the one or more separator screens, the vibratory motor comprising:
a motor;
a lower weight set operatively coupled to a lower end of the motor; and
an upper weight set operatively coupled to an upper end of the motor, the upper weight set comprising:
a base plate rotatable about an axis and extending radially outward from the axis;
a plurality of slots extending through the base plate between the axis and a periphery of the base plate;
a plurality of weights coupled to each other about the base plate; and
a weight locking tab that partially surrounds the base plate comprising one or more hooks, wherein each hook extends through at least a portion of a slot.

14. The vibratory separator of claim 13 , wherein the at least one hook is sized such that, when the weight locking tab is lifted, the hook completely rises out of the slot.
