Abstract
A cement mixer truck that has an extendable chute assembly that permits extending one, two or more chute sections for discharge of concrete at a location remote from the mixer. The chute section is easily telescopic, can be locked in either the retracted or extended positions, and can be swiveled about a vertical axis. Further, for storage, the chutes will fold up automatically when at a proper position to engage an actuator to cause the chutes to fold. The truck shown is a front discharge mixer truck that can be adjusted in vertical height at a job site to permit a greater slope to the chutes and is available with a restricted height truck.
Claims20
A discharge chute assembly for discharging material from a discharge apparatus having a storage reservoir, the discharge chute assembly comprising a first discharge chute section for receiving the material from the reservoir:
- a second chute section comprising a trough-shaped body extending longitudinally between a second inlet end and a second outlet end and having spaced upper edges, means to couple the inlet end to the first chute section to receive materials from the first chute section;
- a third chute section comprising a body of complemental cross-sectional shapes to the second chute section and being of larger size so as to telescopically slide over the second chute section and moveable to extend outwardly from the second chute section and having a pair of edges extending longitudinally between a third inlet end and a third outlet end;
- and
- fastening means connecting the third inlet end to the second outlet end for pivotable movement of the third chute section with respect to the second chute section, and permitting detachably disconnecting the third inlet end from the second outlet end for telescopically sliding movement of the third chute section relative to the second chute section.
A vehicle having a frame and wheeled front and rear support axles supporting the frame, a storage body mounted on the frame and which includes an outlet means for discharging stored material into an extendable discharge chute for transporting the material to be discharged to a remote location;
- said outlet being located horizontally adjacent to and above the front axle of the vehicle, and linkage means and fluid pressure extendable and retractable spring means connected between the axle of the vehicle and the frame, and including selectively operable means to extend said fluid pressure spring means to raise the frame and the storage body relative to the front axle whereby the gravity flow of material to be discharged from the storage body through the chute is enhanced and the distance of the material discharged is increased.
A telescopic chute assembly for conveying materials discharged from a reservoir comprising:
- a first chute having a body of generally U-shaped cross section with a pair of edges extending longitudinally between an inlet end and an outlet end and having means for mounting the first chute to a reservoir;
- a second chute having a body of generally U-shaped cross section with a size larger than the first chute and extending longitudinally between an inlet end and an outlet end;
- fastening means having a pair of receiving brackets mounted at the outlet end on respective edges of the first chute and a pair of mating supports mounted on respective edges at the inlet end of the second chute being supported by and slidable along the edges of the first chute permitting telescopically slidable movement of the second chute longitudinally relative to the first chute to extend from the first chute and to retract at least partially over the first chute, and the mating supports being detachably and pivotally mountable to the receiving brackets to permit securing the inlet end of the second chute to the outlet end of the first chute and releasing the second chute from the first chute.
A chute assembly mounted to a main chute on a concrete mixer vehicle frame comprising:
- a first chute mounted to the main chute and having a body with a lower portion in a generally semi-circular cross section with a pair of edges extending longitudinally between an inlet end and an outlet end;
- a second chute having a body with a lower portion in a generally semi-circular cross section with a diameter larger than the first chute and with a pair of edges extending longitudinally between an inlet end and an outlet end;
- fastening means having a pair of hook means mounted at the outlet end on respective edges of the first chute and a pair of ears mounted at the inlet end on respective edges of the second chute being supported by and slidable over the edges of the first chute permitting telescopically slidable movement of the second chute longitudinally relative to the first chute, and the ears being detachably mountable to the hook means to permit securing the inlet end of the second chute to the outlet end of the first chute releasing the second chute from the first chute;
- and
- lift means having a selectively distensible body generally supporting the vehicle frame for raising and lowering the vehicle frame to selectively change vertical height of the main chute.
