10. The apparatus for preparing concentrated organic fertilizer as claimed in claim 9, wherein the apparatus is operated by the steps of:

the first step is as follows: the materials are put on the conveyer belt, the rotating movable material cutting knife (29) feeds the materials on the conveyer belt inwards, and the rotating movable material cutting knife (29) is matched with the fixed material cutting knife (28) to cut the materials when rotating;

the second step is that: the cut materials fall into the feeding pipe (2) to freely fall, the falling materials are firstly crushed through the rotation of the crushing rod (401), the crushed materials are soaked by phosphorus-containing liquid sprayed from the water spraying holes (402) when falling to the height of the water spraying holes (402), and the soaked crushed materials fall onto the grinding head (403) and are ground by the grinding head (403) and the grinding block (26) and then enter the material conveying pipe;

the third step: forming a first chamber (1001) and a second chamber (1002) in the first mounting hole (101) through the end cap (102) and the mating ring (141); the combustion gas is added into the second chamber (1002) and then the second chamber (1002) is ignited, the gas in the second chamber (1002) is combusted to generate high-temperature and high-pressure gas to push the double-headed piston (14) to move towards the conveying pipe (8), the head of the double-headed piston (14) is propped into the first through hole (801), and the conveying pipe (8) can rotate when the double-headed piston (14) is propped against the center line of the double-headed piston (14) because the center line of the double-headed piston (14) and the center line of the first through hole (801) are deviated; after combustion gas is added into the first chamber (1001), the second chamber (1001) is ignited, the gas in the first chamber (1001) is combusted to generate high-temperature high-pressure gas to push the double-headed piston (14) to move towards the inner power pipe (11), meanwhile, the high-temperature gas in the second chamber (1002) is discharged, the head of the double-headed piston (14) is propped into the second through hole (111), and the inner power pipe (11) can rotate when being propped by the double-headed piston (14) due to the fact that the center line of the double-headed piston (14) is deviated from the center line in the second through hole (111); the internal power pipe (11) rotates to drive the internal gear (802) to rotate through the external gear (112), and the internal gear (802) drives the transmission pipe (8) to rotate;

the fourth step: the materials move forwards slowly under the action of the helical blades (9) in the material conveying pipe (1), heat is generated by ignition and combustion in the first mounting hole (101), and is transferred to the conveying pipe (8) through the gap between the conveying pipe (8) and the power pipe (10) to heat the materials in the material conveying pipe (1) so that the materials are rapidly fermented, and meanwhile, the helical residual heat pipe (5) is beneficial to heating and heat preservation of the material conveying pipe (1) by the heat generated by the power pipe (10);

the fifth step: the fermented material is discharged through the discharging head (24), the fermented material is crushed through the rotation of the crushing head (7), meanwhile, the material falling into the material returning hole (702) is conveyed to the feeding end of the material conveying pipe (1) through the material returning pipe (6) by the material returning screw (26) to be mixed with the material to be fermented, and the fermentation process to be fermented is accelerated through a large amount of microorganisms contained in the fermented material.
