The present disclosure relates to buckets for excavation machinery, and more particularly to a toothed bucket for excavation machinery.
This section provides background information related to the present disclosure which is not necessarily prior art.
Ripper attachments that couple to excavation machinery, such as a backhoe, a front-end loader, an excavator, and the like have been used for supplementing and complementing the digging action of a bucket coupled to the end of a tractor linkage, or boom, of the excavation machine. In particular, ripper attachments, which are typically welded or bolted to the bucket, facilitate the breaking up of materials generally resistant to removal. This is advantageous because the loosened material is more readily picked up by the bucket by concentrating the bucket force over smaller contact points, thus enabling increased bucket loads and enhancing the efficiency of the excavation equipment.
Some ripper attachments are pivotally secured to the backside of a bucket in a position such that the ripper tip pivots about a horizontal axis to an operative position when the bucket is tucked or folded upwardly. A problem with the pivotal ripper attachment is that a load is transmitted through the ripper attachment to its pivotal axis on the bucket, and to a blunt end formed on the top side of the ripper attachment at a location where the top of the attachment contacts the bucket. The hard metal of the ripper attachment at this location can wear into and damage the bucket, or otherwise compromise the functionality of the bucket or other components of the excavation machine.
Accordingly, there is a continuing need for an improved, toothed bucket for excavation machinery.
In concordance with the present disclosure, an improved, toothed bucket for excavation machinery, has surprisingly been discovered.
The present technology includes articles of manufacture, systems, and processes that relate to buckets for excavation machinery, and more particularly to a toothed bucket for excavation machinery. A bucket can be configured to be used with excavating equipment in various configurations. The bucket can include a bucket body. The bucket body can have a cutting edge. The cutting edge can include a plurality of cutting teeth. Each one of the cutting teeth can be independently moveable relative to the bucket body.
Advantageously, the bucket of the present disclosure can be configured to more efficiently dig through difficult to excavate material, for example, when dredging below a water surface or performing earth moving of any kind on land. The modification to the bucket can break up material such as road material and other dense materials, as non-limiting examples. The concept can be applied in marine and land construction projects. The bucket can also eliminate the need for multiple pieces of equipment by combining features of certain other excavating equipment.
In one embodiment, a bucket for excavating a material comprises a bucket body having a cutting edge, an actuator disposed adjacent to the cutting edge of the bucket body, and a cutting tooth coupled to the actuator. The cutting tooth is configured to be selectively moveable by the actuator with respect to the bucket body to facilitate an excavation of the material with the bucket.
In another embodiment, a bucket for breaking and moving a material comprises a bucket body having a cutting edge, a hollow compartment formed in the bucket body, and an access panel configured to removably cover the hollow compartment. An actuator is disposed adjacent to the cutting edge of the bucket body and a cutting tooth is coupled to the actuator. The cutting tooth is configured to be selectively moveable by the actuator with respect to the bucket body to facilitate a breaking and moving of the material with the bucket. A connector is disposed in the hollow compartment of the bucket body. The connector has one end in communication with the actuator and a second end configured to be in communication with an energy source, the energy source utilized to selectively energize the actuator and cause a movement of the cutting tooth.
In yet another embodiment, a method of excavating a material with a bucket comprises the steps of providing a bucket including a bucket body having a cutting edge, an actuator disposed adjacent to the cutting edge of the bucket body, and a cutting tooth disposed adjacent an end of the actuator. The cutting tooth is configured to be selectively moveable by the actuator with respect to the bucket body to facilitate an excavation of the material with the bucket. The method further comprises performing one of causing a movement of the cutting tooth relative to the bucket body, breaking the material being excavated utilizing the movement of the cutting tooth, ceasing the movement of the cutting tooth relative to the bucket body, scooping up the material broken by the cutting tooth into the bucket body, and transporting the material broken by the cutting tooth in the bucket body.
Further areas of applicability will become apparent from the description provided herein. The description and specific examples in this summary are intended for purposes of illustration only and are not intended to limit the scope of the present disclosure.
The drawings described herein are for illustrative purposes only of selected embodiments and not all possible implementations, and are not intended to limit the scope of the present disclosure.
The following description of technology is merely exemplary in nature of the subject matter, manufacture, and use of one or more inventions, and is not intended to limit the scope, application, or uses of any specific invention claimed in this application or in such other applications as can be filed claiming priority to this application, or patents issuing therefrom. Regarding methods disclosed, the order of the steps presented is exemplary in nature, and thus, the order of the steps can be different in various embodiments, including where certain steps can be simultaneously performed.
The terms “a” and “an” as used herein indicate “at least one” of the item is present; a plurality of such items can be present, when possible. Except where otherwise expressly indicated, all numerical quantities in this description are to be understood as modified by the word “about” and all geometric and spatial descriptors are to be understood as modified by the word “substantially” in describing the broadest scope of the technology. The term “about” when applied to numerical values indicates that the calculation or the measurement allows some slight imprecision in the value (with some approach to exactness in the value; approximately or reasonably close to the value; nearly). If, for some reason, the imprecision provided by “about” and/or “substantially” is not otherwise understood in the art with this ordinary meaning, then “about” and/or “substantially” as used herein indicates at least variations that can arise from ordinary methods of measuring or using such parameters.
Although the open-ended term “comprising,” as a synonym of non-restrictive terms such as including, containing, or having, is used herein to describe and claim embodiments of the present technology, embodiments can alternatively be described using more limiting terms such as “consisting of” or “consisting essentially of.” Thus, for any given embodiment reciting materials, components, or process steps, the present technology also specifically includes embodiments consisting of, or consisting essentially of, such materials, components, or process steps excluding additional materials, components or processes (for consisting of) and excluding additional materials, components or processes affecting the significant properties of the embodiment (for consisting essentially of), even though such additional materials, components or processes are not explicitly recited in this application. For example, recitation of a composition or process reciting elements A, B and C specifically envisions embodiments consisting of, and consisting essentially of, A, B and C, excluding an element D that may be recited in the art, even though element D is not explicitly described as being excluded herein.
As referred to herein, disclosures of ranges are, unless specified otherwise, inclusive of endpoints and include all distinct values and further divided ranges within the entire range. Thus, for example, a range of “from A to B” or “from about A to about B” is inclusive of A and of B. Disclosure of values and ranges of values for specific parameters (such as amounts, weight percentages, etc.) are not exclusive of other values and ranges of values useful herein. It is envisioned that two or more specific exemplified values for a given parameter may define endpoints for a range of values that may be claimed for the parameter. For example, if Parameter X is exemplified herein to have value A and also exemplified to have value Z, it is envisioned that Parameter X may have a range of values from about A to about Z. Similarly, it is envisioned that disclosure of two or more ranges of values for a parameter (whether such ranges are nested, overlapping or distinct) subsume all possible combination of ranges for the value that might be claimed using endpoints of the disclosed ranges. For example, if Parameter X is exemplified herein to have values in the range of 1-10, or 2-9, or 3-8, it is also envisioned that Parameter X may have other ranges of values including 1-9, 1-8, 1-3, 1-2, 2-10, 2-8, 2-3, 3-10, 3-9, and so on.
When an element or layer is referred to as being “on,” “engaged to,” “connected to,” or “coupled to” another element or layer, it can be directly on, engaged, connected, or coupled to the other element or layer, or intervening elements or layers can be present. In contrast, when an element is referred to as being “directly on,” “directly engaged to,” “directly connected to” or “directly coupled to” another element or layer, there can be no intervening elements or layers present. Other words used to describe the relationship between elements should be interpreted in a like fashion (e.g., “between” versus “directly between,” “adjacent” versus “directly adjacent,” etc.). As used herein, the term “and/or” includes any and all combinations of one or more of the associated listed items.
Although the terms first, second, third, etc. can be used herein to describe various elements, components, regions, layers and/or sections, these elements, components, regions, layers and/or sections should not be limited by these terms. These terms can be only used to distinguish one element, component, region, layer or section from another region, layer, or section. Terms such as “first,” “second,” and other numerical terms when used herein do not imply a sequence or order unless clearly indicated by the context. Thus, a first element, component, region, layer, or section discussed below could be termed a second element, component, region, layer, or section without departing from the teachings of the example embodiments.
Spatially relative terms, such as “inner,” “outer,” “beneath,” “below,” “lower,” “above,” “upper,” and the like, can be used herein for ease of description to describe one element or feature's relationship to another element(s) or feature(s) as illustrated in the figures. Spatially relative terms can be intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements described as “below”, or “beneath” other elements or features would then be oriented “above” the other elements or features. Thus, the example term “below” can encompass both an orientation of above and below. The device can be otherwise oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.
The present technology improves buckets for excavation machinery, and more particularly, relates to a toothed bucket for excavation machinery.
With reference to
The bucket 100 can include a bucket body 102 having a cutting edge 104. In operation, the cutting edge 104 can be configured to contact the ground and to guide any debris or excavated material into the bucket body 102. The bucket body 102 can then be used to transport or move the debris and/or the excavated material to a desired secondary location.
The cutting edge 104 can include one or more cutting teeth 106 disposed along a length thereof. The cutting teeth 106 can be configured to vibrate or otherwise be movable relative to the bucket body 102. Advantageously, the vibration or movement of the cutting teeth 106 can allow for increased efficiency when digging or excavating with the bucket 100 by facilitating a breaking up of compact debris and material and then scooping-up the broken debris and material with the bucket body 102.
In one embodiment, an actuator 108 is disposed on or within the bucket body 102 adjacent to the cutting edge 104. One or more of the cutting teeth can be coupled to the actuator 108, wherein the actuator 108 is configured to cause the movement of the cutting teeth 106 coupled to the actuator 108. For example, the actuator 108 can control a repeated cycle of outward and inward movements of the cutting teeth 106, where one cycle of outward and inward motion is a stroke. As a non-limiting example, the actuator 108 can be configured to provide, individually or in combination, a lateral, longitudinal, rotational, vibrational, or other movement to the one or more cutting teeth 106 attached thereto. Furthermore, a plurality of the actuators 108 can be provided adjacent the cutting edge 104 of the bucket body 102. Each of the actuators 108 can have one or more cutting teeth 106 coupled thereto and each of the actuators 108 can be configured to provide independent movement of the cutting teeth 106 coupled thereto as compared to the cutting teeth 106 coupled to the other actuators 108. It should be understood that the cutting teeth 106 can be removable from the actuator 108 to facilitate a replacement of the cutting teeth 106 and/or a utilization of cutting teeth 106 of different shapes and sizes, allowing the cutting teeth 106 to be specially configured for specific materials or excavation projects.
It should be appreciated that since each of the cutting teeth 106 is configured to be moved independently, the cutting teeth 106 can be moved in various predetermined patterns. For example, one pattern can include all of the cutting teeth 106 moving in unison such that each of the cutting teeth 106 strokes at the same time. Another pattern can include alternating the strokes of adjacent cutting teeth 106 such that when a first set of the cutting teeth 106 are on an upstroke, a second set of the cutting teeth 106 can be on a downstroke. A further pattern can include only moving a portion of the cutting teeth 106 at a specific location along the length of the bucket body 102.
In certain embodiments, the frequency of the strokes of each of the cutting teeth 106 can be adjusted, as desired. In other embodiments, each of the cutting teeth 106 can have a different frequency based on project need. It should be appreciated that any suitable frequency of strokes can be utilized by a skilled artisan, as desired.
As a non-limiting example, the actuator 108 can be a hydraulic actuator. However, other suitable types of actuators, including electric and pneumatic actuators, are also contemplated and considered within the scope of the present disclosure. As shown in
A controller 122 can be provided and used by an operator of the bucket 100 to selectively control the actuator 108 and thereby control the movement of the cutting teeth 106. As a non-limiting example shown in
With particular reference to
The bucket body 102 can include an access panel 114 configured to be removably attached to the bucket body 102 for covering cover the hollow compartment 110. When attached to the bucket body 102, the access panel 114 can provide protection to any control components that may be contained within the hollow compartment 110 and the connector 112 within the hollow compartment 110. The access panel 114 can be removed to allow the operator to access the control components that may be stored within the hollow compartment 110 and to connect the source of energy to the actuator 108 and/or the other control components. In certain, embodiments the access panel 114 includes means 118 for the energy from the energy source 120 to pass through the access panel 114 and be available to be placed in communication with the actuator 108 and any other control components therein. The means 118 for passing the energy through the access panel 114 can include various types of apertures, such as a through hole, configured to permit a pneumatic hose, a hydraulic hose, or an electrical line to pass through the access panel. The means 118 for passing the energy through the access panel 114 can also be a coupler for attaching one of a pneumatic hose, a hydraulic hose, or an electrical line to an outer surface of the access panel 114 and a corresponding hose or line to an inner surface of the access panel. Other means 118 for passing the energy through the access panel 114 can also be provided to the access panel 114, as desired.
