[0016] Briefly stated, the invention comprises a mobile bin having frame with a bin mounted thereon with wheels for transporting the bin on the ground, a first conveyor is mounted along the bottom of the bin and extends to one end of the bin for conveying material from with the bin to the one end of the bin, a second belt conveyor has a mounting frame which is pivotally mounted at the one end to the one end of the bin to pivot about a vertical axis to pivot the second belt conveyor about a vertical axis beneath the one end of the bin, a channel for slidably receiving the second conveyor is pivotally mounted to the mounting frame to pivot about a horizontal axis and the second conveyor is slidably mounted in the channel, hydraulic power means are provided to slide the second conveyor along the channel to change the position of the second conveyor relative to the first conveyor horizontal beneath the end of the first conveyor, and second hydraulic power means are provided to pivot the channel and second conveyor upward and downward about the horizontal axis and a third hydraulic power means are provided to pivot the mounting frame about its vertical axis.

[0017] Referring more particularly to the drawings, in FIG. 1,2, and 3 the mobile bin invention 20 is illustrated having a bin 21 mounted on a frame 22 and a first conveyor 23 mounted beneath the bin and with a second conveyor 24 slidably adjustable in length and a conveyor receiving frame 25 which frame slidably receives the second conveyor 24. The sliding conveyor frame 25 is pivotally mounted to the pivot frame 26 by a horizontal pivot pins 25′ to pivot about a horizontal axis relative to a pivot frame 26. The pivot frame 26 is pivotally mounted to the bin frame 21 to pivot about a vertical axis relative to the bin, bin frame and the pivot carrier frame 25 by a pivot 27 which is mounted between the frame 21 of the device and the one vertical leg 26″ of the U shaped pivot frame 26.

[0018] The slidably second conveyor 24 is slidably mounted in the pivotal carrier frame 25 to slide along its length along the pivotal frame. The slidable second conveyor 24 is pivoted by the pivot frame 26 about the pivot 27 to a position beneath outlet end 23′ of the first conveyor means. When the slidable conveyor is pivoted beneath the outlet end of the first conveyor, the slidable movement of the conveyor relative to the pivot frame acts to adjust the distance of the outer end 24′ of the second conveyor means to the outlet end 23′ of the first conveyor means. A first hydraulic piston and cylinder 28 is mounted beneath the carrier or sleeve frame 25 with its cylinder pivotally mounted to the frame 25 and its piston pivotally mounted to the sliding second conveyor 24 whereby telescoping the piston 28′ in the cylinder 28″ will slide the conveyor 24 along the sliding frame 25. The second conveyor 24 is slidable along the carrier frame 25 to slide the second conveyor along the outlet end 23′ of the first conveyor 23 to move the outlet end 24′ of the second conveyor toward the outlet end of the first conveyor while the other end of the second conveyor moves away from the outlet end of the first conveyor, and while maintaining the belt 30 along its upper face 30′ continuously beneath the outlet end of the first conveyor so that a selected upper portion of the belt will always receive material leaving the outlet end 23′ of the first conveyor with the selected receiving portion of the belt depending upon what selected portion is adjustably located beneath the outlet end of the first conveyor when sliding the sliding second conveyor along the sliding frame.

[0019] A second piston and cylinder 32 pivotally mounted between the bin frame and the pivot frame 26 with the cylinder 32′ pivotally mounted to the frame at 32″ and the piston 32″ pivotally mounted to the pivot frame 26 at pivot 42 to pivot the pivot frame 26, the sliding frame 25 and the sliding conveyor 24 about the vertical axis of the pivot mounting 27 of the pivot frame 26 to the bin frame 21. A third piston and cylinder 33 acts as a raising and lowering piston and cylinder 33 for the second conveyor, with its piston 33′ pivotally mounted to the sliding carrier frame 25 and its cylinder 33″ pivotally mounted to the pivotal frame 26 to pivot about pins 25′ pivotally mounting the side panels 34 and 34′ of the carrier frame 25 to the side panels 26′ and 26″ of the pivot frame 26.

[0020] The carrier frame 25 has a elongated bottom panel 35 and the pair of side panels 34 and 34′ formed together to form a U shaped channel. The slidable second conveyor 24 has a pair of elongated side panels 36 and 36′ and a pair of rollers or drums 31 and 31′ rotatably mounted at each end of the side panels with the endless belt 30 rotatably mounted about the drums so that powering one of the drums, for example rotates the endless belt 30.

[0021] The conveyor belt 23 is powered by a reversable motor 38 which drives the drum 40′ which rotates the endless belt 38 which in turn rotates the drum 40 rotatably mounted at the other end of the bin. A motor 44 powers and rotates drum 40 powering the belt in the direction of the other end of the bin will convey the material in the bin to another adjustable belt conveyor which may mounted at the other end 41 of the bin. Overload slip clutches 37′ are mounted between the motor shaft and drums of the motors powering the belt drum.

[0022] Thus, it will be seen that a novel mobile bin has been provided with a conveyor to convey material to one end of the bin a novel second conveyor which is slidably mounted to a channel to slide along its length the channel to change its the portion of the second conveyor positioned beneath the one end of the first conveyor to change the output location of the second conveyor in relation to the first conveyor.

[0023] It will be obvious that various changes and departures may be made to the invention. without departing from the spirit and scope thereof and accordingly, it is not intended that the invention be limited to that specifically described in the specification or as illustrated in the drawings but only as set forth in the appended claims wherein;
