Abstract
The telescopic chute assembly may be used to discharge cement from a discharge end of a concrete mixer mounted on a truck. The chute assembly has several telescopic chute sections for receiving the material from the mixer. The chute sections have a plurality of aligned flat strips that are attached to one another at an angle to form an elongate trough-shaped body to reduce the friction between the cement and the chute sections.
Claims14
A telescopic chute assembly for discharging material from a discharge apparatus having a storage reservoir, comprising:
- a first chute section for receiving the material from the reservoir, the first chute section having a first outlet end, the first chute section having a first width and a first height, the first height being at least as great as the first width;
- a second chute section extending longitudinally between a second inlet end and a second outlet end, the second inlet end being slidably attached to the first outlet end of the first chute section to receive material from the first chute section;
- a third chute section comprising a body of a complemental cross-sectional shape to the second chute section and being of larger size so as to telescopically slide over the second chute section and movable to extend outwardly from the second chute section, the third chute section extending longitudinally between a third inlet end and a third outlet end;
- each of the first, second and third chute section comprising a plurality of aligned flat strips that are disposed relative to one another at an obtuse angle to form a rounded bottom section that comprises a plurality of buckled angle sections of an elongate trough-shaped body;
- and
- means for improving a fluid flow of the discharging material by reducing a friction formed between the buckled angle sections and the discharging material.
A telescopic chute assembly for discharging material from a discharge apparatus having a storage reservoir, comprising:
- a first chute section for receiving the material from the reservoir, the first chute section having an upwardly facing curved inner wall that forms a rounded bottom portion, the curved inner wall having a plurality of elongate first grooves defined therein and extending from a first inlet end to a first outlet end of the first chute section;
- a second chute section extending longitudinally between a second inlet end and a second outlet end, the second inlet end being slidably attached to the first outlet end of the first chute section to receive material from the first chute section, the second chute section having a plurality of elongate second grooves defined therein, the second grooves being aligned with the first grooves;
- 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 movable to extend outwardly from the second chute section, the third chute section extending longitudinally between a third inlet end and a third outlet end;
- a receiver unit attached to the chute assembly for receiving a signal to extend or retract the second and third chute sections relative to the first chute section;
- a remote switching unit adapted to transmit the signal to the receiver unit to activate the receiver unit to extend or retract the second and third chute sections;
- and
- means for improving a fluid flow of the discharging material by reducing a friction formed between the buckled angle sections and the discharging material.
