Earth equipment maintenance tool

Abstract

The disclosed invention facilitates the removal of dirt and other sediment from a bucket of heavy machinery. With regular use, buckets build up dirt that decreases the available volume. Removing the dirt can require additional equipment and labor, and would require the heavy machinery to be away from the service area. The disclosed invention allows for rapid removal of the dirt on site with a single piece of equipment.

DETAILED DESCRIPTION OF EXEMPLARY EMBODIMENTS

(9) The cleaning device 100 consists of a pipe 105 with an load adaptor 110 on the first end and a scraper adaptor 120 on the second end. In the exemplary embodiment, the load adaptor 110 and scraper adaptor 120 are identical, but may be different in alternative embodiments. The load adaptor 110 comprises a load cap 112 and a load plate 114. The scraper adaptor 120 comprises a scraper cap 122 and a scraper plate 124. The load adaptor 110 and the scraper adaptor 120 in the exemplary embodiment are rectangular plates of metal that extend away from the pipe 105.

(10) In operations as shown in FIGS. 2A-C, the cleaning device 100 is placed level on the ground 220, where both the load adaptor 110 and the scraper adaptor 120 are flat on the ground 220. As the vehicle 205 rolls over the load adaptor 110, the load adaptor 110 is pushed into the ground 220 beneath the vehicle 205. The surrounding ground 220 acts as a fulcrum, causing the opposite end of the cleaning device 100 with the scraper adaptor 120 to rise off the ground 220. The force of the vehicle 205 pushing down on the load adaptor 110 of the cleaning device 100 also holds the cleaning device 100 in place, making it resistant to movement as long as the vehicle 205 rests on it.

(11) The cleaning device 100 may now work with the bucket 210 as it is now fixed with respect to the vehicle 205. The scraper adaptor 120 is now above the ground 220 with the scraper adaptor 120 parallel to the orientation of the bucket 210, which is also parallel to the ground 220. The vehicle 205 then positions the bucket 210 so that the scraper adaptor 120 will enter the bucket 210. The bucket 210 acts on the scraper adaptor 120, pushing the scraper adaptor 120 against the bucket interior 212. As the bucket 210 moves, the scraper plate 124 moves with respect to the bucket interior 212, pushing the debris loose and out of the bucket 210.

(12) With the debris removal completed, the bucket 210 moves away from the scraper adaptor 120, freeing the cleaning device 100 to lower as needed. The vehicle 205 then moves off the load adaptor 110, causing the cleaning device 100 to return to the level of the ground 220.

(13) In an alternative embodiment shown in FIG. 2B, the load adaptor 110 and the scraper adaptor 120 may be in different shapes. In an alternative embodiment, the load plate 114 may remain rectangular, while the scraper plate 124 may be curved or oriented at a different angle to facilitate a particular scraping techniques.

(14) In a further alternative embodiment shown in FIGS. 1E and 1F, cleaning device 110 uses a bent pipe 105. While the cleaning device 100 would remain flat on the ground 220 when not in use, the load plate 114 might be in a non-parallel orientation to the ground 220. As the vehicle 205 rolls onto the cleaning device 100, the load plate 114 is forced to rotate under the weight of the vehicle 205. This causes the cleaning device 100 to rotate. As the rotation occurs, the level of the scraper adaptor 120 is impacted by both the load of the vehicle 205 on the load plate 114 and the bend in the pipe 105. This may lower or raise the position of the scraper adaptor 120 as applicable. In operations, the cleaning device 110 may be used as previously described, but may result in the scraper adaptor 120 being at a different height per the design.

(15) In alternative embodiment in FIGS. 1A and 1B, the scraper may have a transportation projection 140 with a transportation eye 142 dimensioned to accommodate the teeth 214 of bucket 210, allowing the vehicle 205 to transport the cleaning device 100 as shown in FIGS. 3A-3B. The vehicle 205 uses the teeth 214 of the bucket 210 to interface with the transport eye 142. The bucket 210 then raises up and the vehicle 205 moves the cleaning device 100 as needed.
