NOVELTY - The device comprises a frame type main bracket, a moving mechanism provided at a lower end of the main bracket, and a secondary bracket internally sleeved on the main bracket. The moving mechanism comprises a moving track and a moving wheel mounted under the main bracket. An upper end of the secondary bracket is parallely set with a first synchronous rotating shaft and a second synchronous rotating shaft. The first synchronous rotating shaft and the second synchronous rotating shaft are set with a lifting chain wheel. The lifting chain wheel is fixed on a side portion of the main bracket.    USE - The device is useful for preparing an organic fertilizer (claimed).    DETAILED DESCRIPTION - The device comprises a frame type main bracket, a moving mechanism provided at a lower end of the main bracket, and a secondary bracket internally sleeved on the main bracket. The moving mechanism comprises a moving track and a moving wheel mounted under the main bracket. An upper end of the secondary bracket is parallely set with a first synchronous rotating shaft and a second synchronous rotating shaft. The first synchronous rotating shaft and the second synchronous rotating shaft are set with a lifting chain wheel. The lifting chain wheel is connected with a lower portion of the secondary bracket, and is fixed on a side portion of the main bracket. A support is set with a power device to rotate a rotating roller. The rotating roller is set with a stirring fin. The stirring fin comprises a stirring blade. One end of a cutter body is provided adjacent to a fixing hole. Other end of the cutter body is fixed with the stirring blade. The upper end of the main bracket is set with an electric motor. The electric motor is connected with a speed reducer. An output end of the speed reducer is equipped with the lifting chain wheel. The lifting chain wheel includes four chain wheels. A first chain wheel and a second chain wheel of the lifting chain drive the first synchronous rotating shaft. The second chain wheel and a third chain wheel drive the second synchronous rotating shaft. A rotating disk is set with a heating device. The heating device comprises an air source connected with a heat tube. The heat tube is located on a lower end of a disk. The lifting chain wheel is equipped with a concave strip and a convex strip. The synchronous rotating shafts are set with the disk along a radial direction. A periphery portion of the disk is provided with the fixing hole.    An INDEPENDENT CLAIM is included for preparing an organic fertilizer which comprises grooves on both sides of a fermentation tank, providing a walking track and stirring device for the fertilizer, placing organic fertilizer into the grooves, dehydrating to below 50% and spreading rice hulls on the surface. The fertilizer comprises 220-240 pts. wt. organic fertilizer, 55-65 pts. wt. rice hulls, 130-140 pts. wt. humic acid, 10-20 pts. wt. corn stalks and 20-30 pts. wt. coffee grounds.
