Abstract

A bucket for a skid loader has a screw auger with right-hand and left-hand auger fighting which meet in the center on a single shaft. Rotation of the shaft in one direction causes sand or other granular material in the bucket to move toward the end outlets for loading into conventional sandbags. Rotation of the shaft in the opposite direction advances the material in the bucket to the center where it is discharged through a bottom outlet into a bulk bag such as an FIBC bag which is supported on tubes suspended from the bucket on lines. A cover is releasably attached to the bucket to block the bottom outlet when a bulk bag is not being filled.

Claims

1. A self-unloading bucket comprising:

a bucket shell having two ends and a middle portion therebetween;

sandbag outlets formed in each of the ends of the bucket shell;

an FIBC bag outlet formed in the middle portion of the bucket shell;

a double handed auger mounted within the bucket shell between the sandbag outlets, and passing over the FIBC outlet;

wherein the auger has a right-handed auger blade portion and a left-handed auger blade portion which extend to or meet over the FIBC outlet of the bucket;

a reversible motor mounted to the bucket shell and in driving relation to the double handed auger so that the auger moves material in the bucket shell either toward the ends of the bucket shell and the sandbag outlets formed therein or toward the middle portion of the bucket shell and the FIBC outlet formed therein, depending on the direction of rotation of the auger;

further comprising a cover for the FIBC outlet releasably mountable to the bucket shell to close the FIBC outlet and prevent the escape of material therethrough from the bucket;

wherein the cover for the FIBC outlet further comprises;

a rectangular plate having two long edges and two shorter edges, an upper side and a lower side and upwardly angled side flanges joined thereto;

a mounting plate joined to the bottom side of the rectangular plate and extending beyond the short edges on either side of the rectangular plate;

a first part of the mounting plate overlain by a first portion of the bucket shell;

a support plate joined to the rectangular plate and extending over the first part of the mounting plate to form a gap between the support plate and the first part of the mounting plate, which captures the first portion of the bucket shell which overlies the first part of the mounting plate;

a second part of the mounting plate opposite in relation to the first part, the second part overlain by a second portion of the bucket shell; and

a member passing through the second part of the mounting plate and the second portion of the bucket shell which overlies the second part of the mounting plate to releasably affix the cover to the bucket shell.

2. A self-unloading bucket comprising:

a bucket shell having two ends and a middle portion therebetween;

sandbag outlets formed in each of the ends of the bucket shell;

an FIBC bag outlet formed in the middle portion of the bucket shell;

a double handed auger mounted within the bucket shell between the sandbag outlets, and passing over the FIBC outlet;

wherein the auger has a right-handed auger blade portion and a left-handed auger blade portion which extend to or meet over the FIBC outlet of the bucket;

a reversible motor mounted to the bucket shell and in driving relation to the double handed auger so that the auger moves material in the bucket shell either toward the ends of the bucket shell and the sandbag outlets formed therein or toward the middle portion of the bucket shell and the FIBC outlet formed therein, depending on the direction of rotation of the auger;

wherein the reversible motor mounted to the bucket shell is a reversible hydraulic motor, and further comprising;

a hydraulic vibrator mounted to the bucket shell;

a hydraulic circuit which connects the hydraulic motor and the hydraulic vibrator to a reversible hydraulic pump; and

a check valve connected between the reversible hydraulic pump and the hydraulic vibrator which blocks a flow of hydraulic fluid when the hydraulic pump is connected to rotate the double handed auger so that the auger moves material in the bucket shell toward the middle portion of the bucket shell and the outlet formed therein.

3. A self-unloading bucket comprising:

a bucket shell having two ends and a middle portion therebetween;

sandbag outlets formed in each of the ends of the bucket shell;

an FIBC bag outlet formed in the middle portion of the bucket shell;

a double handed auger mounted within the bucket shell between the sandbag outlets, and passing over the FIBC outlet;

wherein the auger has a right-handed auger blade portion and a left-handed auger blade portion which extend to or meet over the FIBC outlet of the bucket;

a reversible motor mounted to the bucket shell and in driving relation to the double handed auger so that the auger moves material in the bucket shell either toward the ends of the bucket shell and the sandbag outlets formed therein or toward the middle portion of the bucket shell and the FIBC outlet formed therein, depending on the direction of rotation of the auger;

further comprising an FIBC bag having a bottom with sides extending upwardly from the bottom to an open top, wherein the bag bottom engages a surface, and wherein the bag is supported on the bucket shell by four straps connected to the FIBC bag sides, the FIBC bag top being open to receive material discharged from the bucket shell through the FIBC bag outlet.

4. The bucket of claim 3 wherein the FIBC bag straps form loops, and the FIBC bag defines a first width between the support straps, and further comprising:

two first support members which are longer than the first width, each first support member passing through two loops formed by two of the straps on the FIBC bag; and

wherein each first support member is supported by two second support members which are spaced apart at their attachment to the first support member but which come together to form one of two releasable attachment members which engages the bucket shell at a location spaced from the FIBC bag outlet, the two releasable attachment members being spaced on opposite sides of the FIBC bag outlet.

5. A self-unloading bucket comprising:

a bucket shell having two ends and a middle portion therebetween;

sandbag outlets formed in each of the ends of the bucket shell;

a bulk bag having sides extending to an open top;

four straps connected to the sides on the bulk bag, the straps extending to the bucket shell to support the bulk bag on the bucket shell;

a bulk bag outlet formed in the middle portion of the bucket shell;

wherein the bulk bag top is positioned to receive material discharged from the bucket shell through the bulk bag outlet;

a double handed auger mounted within the bucket shell between the sandbag outlets, and passing over the bulk bag outlet;

wherein the auger has a right-handed auger blade portion and a left-handed auger blade which extend to or to meet above the bulk bag outlet of the bucket; and

a reversible motor mounted to the bucket shell and in driving relation to the double handed auger to rotate the auger in either a first direction to drive the auger to move material in the bucket shell toward the sandbag outlets in the ends of the bucket shell or to rotate the auger in a second direction to move material in the bucket shell toward the bulk bag outlet in the middle portion of the bucket shell.

6. The bucket of claim 5 wherein the bulk bag engages a surface and wherein each bulk bag strap has a loop formed therein, and wherein the four straps comprise two pairs of straps, each strap in one of the strap pairs being spaced apart from the other strap at least a first distance;

two first support members having a length greater than the first distance, each support member extending through the loops of one of the two pairs of straps on the bulk bag;

wherein each first support member is supported by two second support members which are attached at locations spaced apart on the first support member, the second support members coming together at a single releasable attachment member which engages the bucket shell at a position spaced from the bulk bag outlet, such that the releasable attachment members are spaced on opposite sides of the bulk bag outlet.

7. The bucket of claim 5 wherein the bulk bag outlet further comprises:

9. A self-unloading bucket comprising:
