Abstract
A gravity clean-off magnetic sweeper apparatus that connects to the front of industrial equipment or industrial vehicles where a bucket would normally go. The magnetic sweeper is lifted off the ground slightly and driven around an area to pick up metal debris. The collected debris is then cleaned off of the bottom of the invention by lifting it with the machine and pivoting it downward. As the magnetic sweeper is pivoted downward, the mass of the magnets, which is greater than its attraction force to the metal debris attached to the pan in between the magnet and the debris, allows the magnet to hang vertically, as the pan is forced away from the magnet. This removes the metal debris away from the magnetic field and allows it to fall from the magnetic sweeper.
Description
BACKGROUND

The field of the disclosure relates to sweeper apparatuses, in particular to a magnetic sweeper apparatus.


A magnetic sweeper apparatus is typically configured as an attachment to industrial vehicles or industrial equipment to assist in using magnetism to pick up ferrous or metallic objects.


In some instances, some industrial equipment does not have hydraulics available to run attachments with. For example, only a small percentage of backhoe loaders and wheel loaders have hydraulics readily available at the front bucket location, where a magnet is preferred to be attached.


The removal of the need for hydraulics or other power function to clean off the magnet, lowers cost and increases the number of pieces of equipment (e.g., Prime Movers) the disclosure can be used on.


It correspondingly makes the product much simpler which greatly reduces the number of parts required to manufacture the product as well as increases the product's reliability and reduces maintenance for the end user.


The attachment can be used without the operator having to exit the vehicle or get assistance to attach hydraulics or assist cleaning off the magnet. This allows one person operation in a very safe and controlled manner from inside the Prime Mover cab.


There is a desire to enable a magnetic sweeper apparatus to attach to industrial equipment without hydraulics support.

SUMMARY

A gravity clean-off magnetic sweeper apparatus that connects to the front of industrial equipment or industrial vehicles where a bucket would normally go. The magnetic sweeper is lifted off the ground slightly and driven around an area to pick up metal debris. The collected debris is then cleaned off of the bottom of the invention by lifting it with the machine and pivoting it downward. As the magnetic sweeper is pivoted downward, the mass of the magnets, which is greater than its attraction force to the metal debris attached to the pan in between the magnet and the debris, allows the magnet to hang vertically, as the pan is forced away from the magnet. This removes the metal debris away from the magnetic field and allows it to fall from the magnetic sweeper.





DETAILED DESCRIPTION

This disclosure solves the problem by using the already designed dumping mechanisms of the machine that the magnetic sweeper is attached to. Loaders, backhoes and skid steers, etc. (Prime Movers), are primarily designed to use a bucket to pick-up and dump materials. This disclosure uses this existing dumping action to pivot the bottom pan of the invention away from the magnet contained within (attached to a pivot point), to clean the metal debris off the bottom and back side of the invention.


The magnet can be split into individually pivoting magnets which can decrease the swinging mass on larger magnet assemblies or to make use of an alternating polarity magnet for applications requiring different sweeping heights.

Operating Instructions


FIGS. 13 to 15 are diagrams illustrating the operating steps of operating the magnetic sweeper. FIG. 13 is a diagram illustrating Step 1 of operating the magnetic sweeper. Step 1 involves picking up metal debris. When operating the magnetic sweeper, it should be as low to the ground as possible (for best performance) but not contacting it. The bottom of the sweeper should be level (or close to) when operating and provide approximately 3″ to 4″ of ground clearance. According to FIG. 13, debris sticks to the bottom of the pan by magnetic forces.



FIG. 14 is a diagram illustrating Step 2 of operating the magnetic sweeper. Step 2 involves lifting the magnetic sweeper off the ground using the vehicle or industrial equipment. Metal debris 1402 under the magnetic sweeper will be picked up and attached to the bottom pan based on magnet forces.



FIG. 15 is a diagram illustrating Step 3 of operating the magnetic sweeper. Step 3 involves cleaning off the collected metal debris. Once the magnetic sweeper 1500 is elevated, the magnet pivot 1504 allows the pan 1508 to move into the shown vertical position and the collected metal debris 1502 will fall off the bottom of the pan 1508. Once the magnet is cleaned off, the magnetic sweeper 1500 is positioned back to a horizontal position where the lift arms are lowered and the magnetic sweeper 1500 can continue sweeping.


According to FIG. 15, the entire chassis of magnetic sweeper 1500 rotates 90 degrees from working condition. The magnet 1506 stays relatively in same sweep position because of gravity. When magnet 1506 moves away, the magnetic force is further away, thus debris 1502 falls off (i.e,. weaker magnetic force).



FIG. 16 is a diagram that illustrates the Gauss (G) measurements for the magnetic strength of the magnetic sweeper. According to FIG. 16, sweeping height A is the distance from the magnet. The following table (also shown in FIG. 16) illustrates the relationship between sweeping height and magnet strength (in Guass):



















Distance A
3″
4″
5″
6″
7″








Gauss (G)
532
428
380
316
270









According to FIG. 16, the closer the sweeping height (Distance A), the stronger the magnetic force and the larger the sweeping height, the smaller the magnetic strength. For example, at 3″, the magnetic strength is 532 G and at 7″, the magnetic strength is 270 G.


According to the disclosure, the magnetic sweeper has a sectional magnet design that allows the steel frame to extend between the magnets which creates a very strong product that can withstand the abuse of being on the front of the industrial equipment (e.g., Prime Mover) near the ground. In some applications it may be beneficial to utilize a single magnet rather than the sectional design.


According to the disclosure, a different size or grade of the magnet assembly can be incorporated. Furthermore, the magnetic sweeper can support either permanent magnets or electromagnetic magnets.


According to the disclosure, an optional debris digging rake can be added as an accessory to the magnetic sweeper to disturb the ground surface to loosen it and allow the magnetic sweeper to pick up debris in the top surface.


According to the disclosure, the magnetic sweeper is designed for a single user to operate and clean it off without help from others. Furthermore, the magnetic sweeper requires no auxiliary power source (e.g., hydraulic, mechanical, or electrical) or a person to clean the debris off the magnet.


According to the disclosure, the magnetic sweeper can be made from steel, stainless steel, aluminum, magnets, rubber and plastics. In other embodiments, other materials may be used.


According to the disclosure, the magnetic sweeper connects to industrial equipment using a universal skid steer attachment plate that enables connection to smaller equipment such as skid steers, tractors, and small loaders.


According to the disclosure, further embodiments of the magnetic sweeper are designed to connect to equipment using a removable bracket that can be modified or designed to fit nearly any loader bucket connection style including skid steer styles and Euro connector styles. Brackets that have been developed now include:

    • A) Blank (This bracket option allows the customer to weld or bolt on other parts to the blank bracket for connection to their equipment)
    • B) Universal Skid Steer Attachment Plate
    • C) Euro Connector (also known as Alo/Quicke/Global)
    • D) Case 570MXT Series 3 Backhoe Connector
    • E) Caterpillar 440 Backhoe Connector
    • F) JRB 416 Connector


According to the disclosure, an alternative embodiment for magnetic debris collection involves having the magnet in a fixed position, and the debris pan on bottom with some type of extended arm on it. This allows the arm to be pressed into the ground by the industrial equipment (Prime Movers) movements, and a spring to return the debris pan back into position for sweeping and collecting more debris.


According to the disclosure Prime Movers is a brand of industrial equipment. It is also a general term for industrial equipment to which an accessory is attached and from which the accessory is powered or controlled.
