Abstract
Abstract An apparatus for transferring waste material from collecting trucks to a transporting vehicle comprises a wheeled stand coupled to the vehicle and a conveyor system for the waste material consisting of an outer and an inner conveyor part pivotally connected to each other. Both conveyor parts have an endless floor belt and pivotally mounted side plates. A drive ramp is pivotally mounted to the outer conveyor part. The two conveyor parts may be assembled into a compact trailer by pivoting the side plates on the floor belt, the ramp into the outer conveyor part, and the outer conveyor part over the inner conveyor part.

Apparatus for transferring waste material from refuse collecting trucks to a transport vehicle having a container for compressing the waste material and for transporting the waste material to a dumping-ground, said apparatus comprising a conveyor for transferring the waste material from the refuse collecting trucks into the container of the transport vehicle, said conveyor having: A. a first conveyor section mounted on a wheeled stand and connectable to the transport vehicle, said first conveyor section having: 1. a first motor driven endless conveyor element, and 2. two substantially vertical side walls pivotably connected to fixed structure of the first conveyor section so as to be foldable over said first conveyor element. B. a second conveyor section pivotably mounted to the first conveyor section and having: 1. a second motor driven endless conveyor element, and 2. two substantially upwardly and outwardly directed side walls pivotably connected to fixed structure of the second conveyor section so as to be foldable over said second conveyor element, said second conveyor section with its side walls folded over the second conveyor element being also foldable over said first conveyor section so as to form a small trailer towable by the transport vehicle.

Apparatus for transferring waste material from refuse collecting trucks to a transport vehicle having a container for compressing the waste material and for transporting the waste material to a dumping-ground, said apparatus comprising a conveyor for transferring the waste material from the refuse collecting trucks into the container of the transport vehicle, said conveyor having: A. a first conveyor section mounted on a wheeled stand and connectable to the transport vehicle, said first conveyor section having: 1. a first motor driven endless conveyor element, and 2. two substantially vertical side walls pivotably connected to fixed structure of the first conveyor section so as to be foldable over said first conveyor element. B. a second conveyor section pivotably mounted to the first conveyor section and having: 1. a second motor driven endless conveyor element, and 2. two substantially upwardly and outwardly directed side walls pivotably connected to fixed structure of the second conveyor section so as to be foldable over said second conveyor element, said second conveyor section with its side walls folded over the second conveyor element being also foldable over said first conveyor section so as to form a small trailer towable by the transport vehicle.
Claim 3
Dependent Claim
62 words
two substantially upwardly and outwardly directed side walls pivotably connected to fixed structure of the second conveyor section so as to be foldable over said second conveyor element, said second conveyor section with its side walls folded over the second conveyor element being also foldable over said first conveyor section so as to form a small trailer towable by the transport vehicle.
Claim 4
Dependent Claim
62 words
two substantially upwardly and outwardly directed side walls pivotably connected to fixed structure of the second conveyor section so as to be foldable over said second conveyor element, said second conveyor section with its side walls folded over the second conveyor element being also foldable over said first conveyor section so as to form a small trailer towable by the transport vehicle.
Claim 5
Dependent Claim
39 words
two substantially vertical side walls pivotably connected to fixed structure of the first conveyor section so as to be foldable over said first conveyor element. B. a second conveyor section pivotably mounted to the first conveyor section and having:
Claim 6
Dependent Claim
39 words
two substantially vertical side walls pivotably connected to fixed structure of the first conveyor section so as to be foldable over said first conveyor element. B. a second conveyor section pivotably mounted to the first conveyor section and having:
Claim 7
Dependent Claim
34 words
Apparatus according to claim 1, wherein the first and second conveyor elements are endless belts driven by a common drive motor, said first conveyor belt being driven substantially faster than said second conveyor belt.
Claim 8
Dependent Claim
32 words
Apparatus according to claim 1, wherein drive-up beams which permit climbing of the refuse collecting trucks are pivotably mounted on the second conveyor section and are foldable over the second conveyor element.
Claim 9
Dependent Claim
118 words
Apparatus according to claim 1, wherein the free ends of the pivotably connected side walls of the first conveyor section are connected to an elastic cloth defining together with the side walls and the first conveyor element an enclosed conveyor channel, wherein protection plates are pivotably mounted on the upper free ends of the side walls of the second conveyor section, said protection plates resting against the side walls in their folded position and serving in their unfolded Position to prevent waste material unloaded from a waste collecting truck from falling to the ground, and wherein bottom plates are provided below the first and second conveyor elements to prevent also conveyed waste material from falling to the ground.
Claim 10
Dependent Claim
43 words
Apparatus according to claim 1, wherein the side walls of the second conveyor section are provided with lips mounted to define retaining flanges for a stay which serves to prevent said side plates in their folded position from engaging the second conveyor element.
Claim 11
Dependent Claim
84 words
Apparatus according to claim 1, wherein the wheeled stand of the first conveyor section has a ground engaging support and a shaft carrying a wheel at each of its ends, said shaft being adjustable between a lower non-operative position and an upper operative position when there is a load on said conveyor so as to unload the wheels and to transmit the load to the ground through the ground engaging support and to the transport vehicle by means of at least one coupling member.
Claim 12
Dependent Claim
29 words
Apparatus according to claim 6, wherein the shaft is movable into said upper position in response to a pressure exerted on the drive-up beams by a refuse collecting truck.
Claim 13
Dependent Claim
59 words
Apparatus according to claim 6, wherein said transport vehicle is provided with rearwardly extending stays and that the wheels are so mounted on the stand that said stand may be guided sideways by means of the stays so that the coupling moves into the correct position in relation to the transport vehicle when said vehicle reverses toward the stand.
Claim 14
Dependent Claim
34 words
Apparatus according to claim 6, wherein said transport vehicle has a bumper preventing other vehicles from driving beneath it and a transverse beam of said bumper is provided with recesses which receive said coupling.
Claim 15
Dependent Claim
46 words
Apparatus according to claim 6, wherein the coupling comprises an arm, which consists of at least two separate portions, which are arranged to be displaced relative to each other by at least one power unit so that the overall length of the arm can be varied.
Claim 16
Dependent Claim
59 words
Apparatus according to claim 10, wherein one portion of the arm is designed to be telescopically inserted in the other portion of the arm, and that the power unit consists of a cylinder with a piston and the cylinder is mounted on one portion of the arm and the piston is mounted on the other portion of the arm.
Claim 17
Dependent Claim
40 words
Apparatus according to claim 1, wherein said transport vehicle is provided with a plate below a feeding opening to define a tub outside the feeding section of the vehicle and that said conveyor extends upwardly and ends above said tub.
Claim 18
Dependent Claim
58 words
Apparatus according to claim 1, wherein the stand includes at least one upwardly directed frame beam, and the frame beam includes at least two separate portions which are arranged to be displaced relative to each other by at least one power unit so that the overall length of the frame beam can be varied for controlling the grade.
