ABSTRACT:
A device and method for holding and delivering a load of particulate material such as wood blocks, wood chips--dry or moist--, and briquettes. A main bin has an open upper end, closed side walls, and a closed bottom wall. A pair of drive shafts are journaled across and in the side walls of the main bin, with a motor therefor. A flexible belt has one end secured to a first such drive shaft on one side of the bin and another end secured to a second such drive shaft on the opposite side of the bin. A continuous chain driven by the motor drives said drive shafts, and there is an idler associated with the chain and one of the drive shafts for reversing the direction of rotation of that drive shaft, so that rotation of the two drive shafts slackens the belt enabling loading. The belt, when tightened and raised, drops the load into said main bin. A pair of side wall members may be secured to the main bin on each side of the flexible belt, and a delivery device is supported by the main bin and extends from one wall of the bin to and through the opposite wall at the lower end of the bin.
