[0029] Specifically, two bottom scrapers 307 are fixed to the bottom of the rotating sleeve 301, and two first elastic springs 308 are arranged on the side away from the center of the two bottom scrapers 307, and a first clamping block 309 is fixed to one end of the two first elastic springs 308, and a first telescopic rod is arranged inside the first elastic spring 308 between the two first clamping blocks 309 and the bottom scrapers 307; a plurality of first clamping grooves 101 that are clamped with the first clamping blocks 309 are provided in a circular array on the inner wall of the fermentation barrel 1; a plurality of positioning rods 204 are fixed in a circular array on the bottom of the stirring shaft 201, and a plurality of positioning grooves 310 that are plugged with the positioning rods 204 are provided on the top of the rotating sleeve 301.

[0030] Furthermore, a servo motor 205 fixedly connected to the top of the stirring shaft 201 is fixedly mounted on the sealing cover 2; a spiral blade 206 is fixed to the side of the stirring shaft 201, and an outer stirring blade 207 is fixed to the side of the stirring shaft 201 outside the spiral blade 206; a heating chamber 102 is arranged at the bottom of the fermentation barrel 1, a heating tube 103 is arranged inside the heating chamber 102, the heating tube 103 is arranged in the shape of a coil, the heating chamber 102 is filled with water, and a heat conduction plate is arranged at the bottom of the fermentation barrel 1 directly above the heating chamber 102.

During this process, the second elastic springs 1075 fixed between the two sliding plates 1072 and the inner wall of the feed chamber 1071 are compressed, so that the fermentation raw materials slide into the feed pipe 104 in sequence along the focusing funnel 1074 and the inclined surfaces 1073 provided on the two sliding plates 1072. When there is no fermentation raw material or the fermentation raw material is too little to generate a sufficiently large force on the inclined surfaces 1073 set on the two sliding plates 1072, a plurality of snap-fitting strips 10721 fixed on one side of one sliding plate 1072 and a plurality of snap-fitting strip grooves 10722 opened on one side of the other sliding plate 1072 are respectively snap-fitted with each other, thereby preventing outside air from entering the fermentation barrel 1 and improving the purity of the gas in the fermentation barrel 1; and by using a forklift to insert and remove the plug 208 set on the top of the sealing cover 2, it is convenient for the operator to remove the sealing cover 2.
