Abstract

A cart for transporting relatively small batches of concrete mixtures, or the like, and having a reservoir for receiving the components of the concrete therein, an agitator assembly mounted in the reservoir and operable for continuously stirring the mixture during transporting thereof from the site of loading of the cart to the site of utilization of the concrete mixture, a pivotal connection between the cart and a wheeled trailer, a hydraulic cylinder operably connected between the trailer and the cart for selectively pivoting the cart in a rearward direction for discharge of the contents from the cart and pivoting the cart to its normal upright transporting position, and the rear of the cart being of a chute-like configuration for facilitating the discharge of the concrete mixture therefrom.

Claims

1. In combination with a wheeled trailer, a cart pivotally secured to the trailer for pivoting in alternate rearward and forward directions to provide a transporting position and materials discharging position for the cart, a materials receiving reservior provided in the cart, chute-like means providing communication between the reservoir and the exterior of the cart for facilitating discharge of the materials therefrom, agitator means disposed within the reservoir for continuous stirring of the materials during transporting thereof in the cart, and wherein the cart comprises a six-sided housing having a first bottom plate pivotally secured to the trailer and a second bottom plate conterminous with the first bottom plate and extending at a planar angle with respect thereto, said second bottom plate having converging side edges cooperating with two of the six sides of the housing to provide said chute-like means.

2. In combination with a wheeled trailer, a cart as set forth in claim 1 wherein the chute-like means is provided with an opening at the outer end thereof, and door assembly means is pivotally secured in the proximity of the opening for alternate opening and closing thereof.

11. In combination with a wheeled trailer, a cart as set forth in claim 1 and including hitch means secured to the rearward portion of the cart for facilitating securing of two of the carts in in-line relation for towing simultaneously by a common towing vehicle.

12. In combination with a wheeled trailer, a cart as set forth in claim 1 wherein the agitator means comprises a centrally disposed rotatable post member journalled within the reservoir, substantially identical oppositely disposed frame means secured to the post member for rotation simultaneously therewith, and a plurality of substantially mutually parallel spaced blades secured within the frame means for moving through the material in the reservoir upon rotation of the central post means about its own longitudinal axis.

13. In combination with a wheeled trailer, a cart as set forth in claim 12 wherein the frame means includes at least one radially outwardly extending arm member having the transverse plane thereof angularly disposed with respect to the plane of the bottom of the cart.

14. In combination with a wheeled trailer, a cart as set forth in claim 12 wherein the transverse plane of the blades is angularly disposed with respect to the direction of rotation of the agitator apparatus.

3. In combination with a wheeled trailer, a cart pivotally secured to the trailer for pivoting in alternate rearward and forward directions to provide a transporting position and materials discharging position for the cart, a material receiving reservoir provided in the cart, chute-like means providing communication between the reservoir and the exterior of the cart for facilitating discharge of the materials therefrom, agitator means disposed within the reservoir for continuous stirring of the materials during transporting thereof in the cart, and including fluid cylinder means pivotally secured to the trailer, rack and gear means secured between the cart and the fluid cylinder, said fluid cylinder cooperating with the rack and gear means for providing first and second pivotal dumping positions for the cart.

4. In combination with a wheeled trailer, a cart as set forth in claim 3 and including fluid cylinder means interposed between the cart and the trailer for providing said pivoting of the cart.

5. In combination with a wheeled trailer, a cart as set forth in claim 3 wherein the agitator means includes power means mounted on the cart for actuation thereof. assembly means is pivotally secured in the proximity of the opening for alternate opening and closing thereof.

6. In combination with a wheeled trailer, a cart as set forth in claim 3 the agitator means comprises a central post means journalled within the reservoir, a plurality of spaced support arm members extending radially outwardly from the central post means, blade means secured to the support arm members and disposed substantially parallel with the longitudinal axis of the central post means for moving through the materials in the reservoir upon rotation of the central post means about its own longitudinal axis.

7. In combination with a wheeled trailer, a cart as set forth in claim 6 wherein the blade members are of a substantially flat L-shaped configuration, with the plane of the blade members being canted with respect to the longitudinal axis of the support arm members.

8. In combination with a wheeled trailer, a cart as set forth in claim 7 wherein the overall length of the blade members decreases in proportion to the distance thereof from the central post means.

9. In combination with a wheeled trailer, a cart as set forth in claim 7 wherein the lowermost leg of the L-shaped configuration is spaced inwardly from the bottom of the cart.

10. In combination with a wheeled trailer, a cart as set forth in claim 3 and including limiting means for limiting the rearward pivotal movement of the cart.

15. In combination with a wheeled trailer, a cart as set forth in claim 3 and including adjustable pedestal means secured to the trailer, and hook means secured to the cart for selective engagement with the pedestal means for securing the cart in the normal towing position therefor.
