Description
- The present application is a Complete application based on Provisional application USSN 60/251,436 filed Dec. 5, 2000. All the disclosure of USSN 60/251,436 is incorporated herein by reference.
- 1. Field of the invention
- The present invention relates to an apparatus for attachment to a loader.
- More specifically, the present invention relates to an apparatus for attachment to a loader for moving materials.
- Farm tractors and loaders are often fitted with buckets for moving various materials such as hay and silage.
- However, with a pivoting bucket having a bottom or base, it is not always possible to extract a load of material particularly if such material is fairly tightly packed.
- The term farm tractor and loader are used throughout the present disclosure to include farm or industrial tractors, mixers or any mechanical means for lifting such as skid loaders or BOBCAT type loaders. BOBCAT is a registered trademark.
- Clam shell type buckets have been proposed in which a bucket includes a clam shell type closure pivotally secured to the bucket. The arrangement with such prior art buckets is such that the operator pushes the bottom plate into the material and then closes the closure downwardly towards the front edge of the plate or tines in order to take a “bite” or load of the material from the remainder of the material. In order to assist in separating the bite from the remainder, such closures have been provided with sharp edges.
- Nevertheless, and particularly when working with relatively tightly packed materials, there is a tendency for the materials to damage the bottom plate or tines.
- The present invention overcomes the aforementioned problem associated with the prior art arrangements by the provision of a bucket having a pivotally mounted front plate which when pivoted from a loading location thereof to a cutting or grab location, cooperates with a sharp or serrated edge defined by the clam shell type closure for reliably cutting and separating a block of silage or the like for transportation thereof.
- Therefore, it is a primary objective of the present invention to provide a clam shell type bucket apparatus which makes a considerable contribution to the art of loading materials.
- The apparatus according to the present invention also reduces the amount of secondary fermentation of the silage because the apparatus provides a clean cut through a block of the silage.
- Other objects and advantages of the present invention will be readily apparent to those skilled in the art by a consideration of the following detailed description of a preferred embodiment of the present invention taken in conjunction with the annexed drawings.
- The present invention relates to an apparatus for attachment to a front or rear loader. The apparatus includes a bucket having a first and a second end. A support is secured to the first end of the bucket for supporting the bucket relative to the loader. A front plate is pivotally secured to the second end of the bucket. A clam shell closure has a first and a second extremity. The first extremity is pivotally secured to the first end of the bucket. The arrangement is such that in operation of the apparatus, when the closure pivots from an open disposition thereof to a closed disposition thereof in which the second extremity of the enclosure cooperates with the front plate, the materials are secured between the bucket, front plate and the closure. The apparatus also includes a device for pivoting the front plate from a first location for loading the materials to a second location in which the front plate cooperates with the second extremity of the closure for cutting a silage block and for moving such materials.
- In a more specific embodiment of the present invention, the bucket further includes a base of generally rectangular configuration. The base has a front edge, a rear edge, and a first and second side edge. A rear wall extends upwardly from the rear edge. A first and a second sidewall extend upwardly from the first and the second side edges of the base respectively.
- Also, each of the sidewalls is of triangular configuration, with each sidewall extending from the rear wall to the front edge of the base.
- Additionally, the support means includes linkage means extending between the loader and the first end of the bucket. The linkage means is pivotally secured to the first end of the bucket.
- A telescopic cylinder extends between the linkage means and the bucket for pivoting the bucket about the linkage means.
- Also, a control means controls the cylinder in order to adjust the position of the bucket relative to the loader.
- The front plate includes an upper and a lower plate, each upper and lower plate having a forward and a rearward end. The upper and lower plates converge toward each other in a direction toward the forward ends.
- The front plate also includes a tubular portion of generally C-shaped cross sectional configuration. The tubular portion is rigidly secured to the rearward ends of the upper and lower plates.
- Also, the front plate further includes a supporting rod, which extends through the C-shaped tubular portion. The rod is rigidly secured to the second end of the bucket. The arrangement is such that pivoting of the front plate relative to the rod and the second end of the bucket is permitted.
- The front plate includes a mounting bracket and a coupling means such that when the bracket is moved, the front plate pivots about the second end of the bucket.
- The closure includes a roof which has a first and a second lateral edge. The roof defines a front and a back wall.
- A first and a second lateral wall extend from the first and second lateral edges of the roof respectively. The arrangement is such that when the closure is in the closed disposition, the front wall cooperates with the front plate.
- More specifically, the front wall defines a serrated or sharp edge which cooperates with the front plate when the plate is disposed in the second location thereof so that material within the bucket is cut and separated by an interaction of the serrated edge and the front plate.
- The means for pivoting the front plate includes at least one linkage arm having a first and a second end. The first end of the linkage arm is pivotally secured to the closure while the second end of the arm is pivotally connected to the front plate. The arrangement is such that when the closure is moved from the open disposition thereof towards the closed disposition thereof, the linkage arm pivots the front plate from the first towards the second location thereof.
- In an alternative embodiment of the present invention, a first actuator pivots the closure between the open and the closed disposition thereof.
- Also, a second actuator pivots the front plate between the first and second locations thereof.
- Additionally, an actuator control is operably connected to the first and second actuators for selectively permitting independent movement of the closure between the open and closed dispositions thereof and for pivoting of the front plate between the first and second locations thereof.
- In a further embodiment of the present invention, the actuator control is operably connected to the first and second actuators for permitting sequentially linked movement of the closure between the open and the closed dispositions thereof and for pivoting the front plate between the first and second locations thereof.
