A feeder of wood into a combustion chamber of a cassette heat-generator is made in the form of a cassette of rectangular cross section, a drive unit with a tensioning device, a block sprocket, a chain, a support plane with a runner, two vertical supports with a crossbar, a block, a steel rope, a suspended load. At the end of cassette a drive unit with a tensioning device is mounted, the last is a shaft, on which there are rigidly secured: a drive sprocket, a cassette drum and a handle of manual drive, and the shaft is pivotally mounted on the tensioning device so that the plane, in which the sprocket rotates, passes through the middle of cassette, while sprocket teeth stand above the bottom of cassette and provide free sliding of a chain thereon, and at the opposite end of cassette the block sprocket is similarly fastened, and in the cassette a support plane with a runner on the bottom of cassette is mounted, and to the front part of the runner the end of chain from the block sprocket is attached, and in the rear part the end of chain from the drive sprocket is connected, in addition at the end of cassette above the drive unit two supports with a crossbeam are mounted, and on the crossbeam the block is mounted, in addition on the rope drum a steel rope is attached and wound around, whose end is passed through the block and at the end a load P is located, besides the height h, from which the load P is lowered, provides for displacement of the support plane from the edge of cassette to the block sprocket. |
