Abstract

A concrete bucket assembly which is rigidly mounted for vertical, tilting, and rotational movement to a forklift vehicle. The concrete bucket is provided with upper and lower ball and socket assemblies. The lower ball and socket assembly secures the bucket to the extending fork of the vertically movable frame of the forklift truck. The upper ball and socket assembly secures the bucket, at the top thereof, to an arm which extends from and is pivotally secured to the vertically movable frame of the forklift vehicle. The hydraulic system of the vehicle is used to move a closure member at the funnel-shaped bottom of the bucket and to also control movement of a chute at the bottom of the bucket.

Claims

1. A concrete bucket assembly disposed for vertical and rotational movement comprising:

a lifting apparatus having support means thereon disposed for vertical and tilting movement;

a concrete bucket having an upper open portion to receive a concrete mixture therein and a lower funneled portion for discharging said concrete mixture;

closure means operable for retaining and directing said mixture into and out of said bucket;

actuating means carried by said lifting apparatus and disposed for actuating said support means for the vertical and tilting movement thereof and for actuating said closure means for opening and closing thereof; and

ball and socket means carried by said bucket and said support means and disposed in substantially axial alignment at said upper and lower portions of said bucket to permit rotational movement thereof.

2. An assembly as set forth in claim 1 wherein said support means includes lower and upper arms horizontally extending from said lifting apparatus in spaced relation, and said upper open portion of said bucket is provided with a member extending thereacross, said ball and socket means including a first ball and socket assembly secured between said lower arm and said bottom portion of said bucket and a second ball and socket assembly secured between said upper arm and said member.

3. An assembly as set forth in claim 2 wherein said lower portion of said bucket is provided with a flanged member extending therefrom, said flanged member having the socket member of said first ball and socket assembly secured thereto, the ball of said socket being secured to said lower arm.

4. An assembly as set forth in claim 3 wherein said upper arm is removably and pivotally secured to said lifting apparatus, said upper arm having the socket of said second ball and socket assembly secured thereto, the ball of said second ball and socket assembly being secured to said member extending across said upper opening.

5. An assembly as set forth in claim 4 including a chute member secured to said bottom portion of said bucket in communication with said funneled portion thereof.

6. An assembly as set forth in claim 5 wherein said closure member is an arcuate cover member rotatably secured adjacent to the bottom of said lower funneled portion of said bucket and operably connected to said actuation means for pivotal movement.

7. An assembly as set forth in claim 6 wherein said lifting apparatus is a forklift truck and said actuation means are operated by the hydraulic control system of said forklift truck.

8. An assembly as set forth in claim 5 wherein said chute member is pivotally secured to the bottom portion of said bucket and operably connected to actuation means for pivoting said chute member in a vertical plane.

9. An assembly as set forth in claim 5 including an auger disposed in said chute member, said auger having the blades thereof displaced in snug fitting relation with the interior surfaces of said chute member whereby said auger blades serve to define said closure means, and means for rotating said auger.

10. An assembly as set forth in claim 9 wherein said chute member includes an open end and a closed end, said means for rotating said auger is a hydraulic motor connected to said actuating means carried by said lifting apparatus.

11. An assembly as set forth in claim 10 wherein said lifting apparatus is a forklift truck and said actuation menas are operated by the hydraulic control system of said forklift truck.
