DETAILED DESCRIPTION

[0018] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0019] Example: See Figures 1-6 A probiotic-based grain fermentation device includes a fermentation tank 1, a feeding cylinder 9 is installed on the outer wall of one side of the fermentation tank 1, a control valve is installed on the feeding cylinder 9, a discharge pipe 10 is installed at the bottom of the fermentation tank 1, and a solenoid valve 11 is installed on the discharge pipe 10; Raw materials required for fermentation are added into the fermentation tank 1 through the feeding cylinder 9 . After fermentation is completed, the solenoid valve 11 is controlled to open and the materials in the fermentation tank 1 are discharged through the discharge pipe 10 .

[0020] A stirring mechanism is also installed inside the fermentation tank 1. The stirring mechanism includes a linkage shaft 12 rotatably connected to the inside of the first transmission shaft 2, a second transmission shaft 13 fixedly connected to the bottom end of the linkage shaft 12, and a plurality of stirring blades 14 fixedly sleeved on the outside of the second transmission shaft 13. The top end of the second transmission shaft 13 abuts the bottom end of the first transmission shaft 2. A bracket 15 is installed on the top of the fermentation tank 1. A first motor 16 is installed on the top of the bracket 15. The output end of the first motor 16 is fixedly connected to the top end of the linkage shaft 12. By controlling the first motor 16 to drive the linkage shaft 12 to rotate counterclockwise, the second transmission shaft 13 rotates synchronously therewith, thereby driving the stirring blades 14 to stir the raw materials inside the fermentation tank 1.

[0021] Also includes: The impurity removal mechanism includes a first transmission shaft 2 rotatably connected to the inside of the fermentation tank 1, a sliding sleeve 3 installed on the outside of the first transmission shaft 2 and a plurality of filter components installed on the outside of the sliding sleeve 3. A key pin is fixedly connected to the outer wall of the first transmission shaft 2 along its length direction, and a key groove is opened inside the sliding sleeve 3 along its length direction. The key pin is slidably connected to the inside of the key groove. Therefore, when the first transmission shaft 2 rotates, the sliding sleeve 3 is driven to rotate synchronously. The filter component includes a filter frame 6 fixed to the outer wall of the sliding sleeve 3 and a filter screen 7 installed on the outer wall of one side of the filter frame 6. A driving component for driving the first transmission shaft 2 to rotate is also installed on the bracket 15. The driving component includes a second motor 17 installed on the top of the bracket 15 and a first one-way gear 18 installed on the outside of the first transmission shaft 2; the output end of the second motor 17 is fixedly connected to a driving gear 19, and the driving gear 19 Engaged with the first one-way gear 18, the impurity removal mechanism also includes a lifting assembly installed inside the fermenter 1, the lifting assembly including a driven shaft 20 rotatably connected to the inner wall of the top of the fermenter 1, a reciprocating screw 21 fixedly sleeved on the outside of the driven shaft 20, and a lifting block 22 threadedly connected to the outside of the reciprocating screw 21; the top end of the driven shaft 20 extends to the inner side of the bracket 15 and is rotatably connected to the inner wall of the top of the bracket 15. A second one-way gear 23 is installed on the outside of the driven shaft 20, and the second one-way gear 23 is meshed with the driving gear 19; the lifting block 22 is also rotatably sleeved on the outside of the sliding sleeve 3; the linkage disk 4 is rotatably connected to the inside of the fermenter 1, and a plurality of through openings 5 ​​are opened through the interior of the linkage disk 4, and the filter frame 6 is adapted to the through opening 5. Therefore, after the filter frame 6 and the filter screen 7 are moved up, the raw materials remaining on the outer walls of the two can be scraped off; At the beginning of fermentation, when the stirring mechanism is stirring the raw materials counterclockwise, the second motor 17 is controlled to drive the driving gear 19 to rotate counterclockwise, and the engagement between the driving gear 19 and the second one-way gear 23 drives the driven shaft 20 to rotate. At this time, the first one-way gear 18 also rotates, but the first transmission shaft 2 does not rotate. When the driven shaft 20 rotates, it drives the reciprocating screw 21 to rotate synchronously, and drives the lifting block 22 to move from the top end of the reciprocating screw 21 to its bottom end, thereby driving the sliding sleeve 3 to move downward synchronously along the outer wall of the first transmission shaft 2, and each filter frame 6 moves downward along the inner wall of the through port 5, so that the lower edge of the filter frame 6 moves down below the liquid level, and the upper edge of the filter frame 6 is located above the liquid level. Therefore, when the stirring mechanism drives the raw materials to rotate counterclockwise, impurities will float to the top of the liquid level during the stirring process. When the impurities pass through the inside of the filter frame 6, the impurities are removed by the filter screen 7. After filtering inside the filter frame 6, the reciprocating screw 21 is driven to continue rotating by controlling the second motor 17, and the lifting block 22 is driven to move from the bottom end of the reciprocating screw 21 to its top end, thereby driving the filter frame 6 to move up and reset through the sliding sleeve 3, so that the inner wall of the bottom of the filter frame 6 and the top of the linkage disk 4 are at the same horizontal height, and then the second motor 17 is controlled to drive the driving gear 19 to rotate clockwise. Through the meshing effect between the driving gear 19 and the first one-way gear 18, the first transmission shaft 2 is driven to rotate counterclockwise, thereby driving each filter frame 6 to rotate synchronously counterclockwise through the sliding sleeve 3, and the impurities filtered inside the filter frame 6 are discharged in the opposite direction to the top of the linkage disk 4 through the reverse centrifugal force. Since the bottom of the filter frame 6 is still inside the through-port 5, the linkage disk 4 rotates accordingly. In this process, the impurities on the top of the linkage disk 4 are thrown to the edge of the linkage disk 4, and the above operation is repeated to process the floating impurities multiple times.

[0022] The extension mechanism includes a guide plate 8 mounted at the bottom of the filter frame 6 and an adjustment assembly for driving the guide plate 8 to rotate. The adjustment assembly includes a plurality of fixed cylinders 25 hinged to the bottom of one side of the filter frame 6 and a slide rod 26 slidably connected to the inside of the fixed cylinder 25; the top of the guide plate 8 is hinged to the bottom of the other side of the filter frame 6; the bottom end of the slide rod 26 is hinged to the bottom of the guide plate 8; a spring 27 is fixed to the inner wall of the top of the fixed cylinder 25, and the bottom end of the spring 27 is fixed to the top of the slide rod 26; When the guide plate 8 is located inside the through-port 5, the through-port 5 limits the guide plate 8, so that the guide plate 8 is in a vertical state. As the filter frame 6 moves downward, the guide plate 8 moves out of the through-port 5. The rebound force of the spring 27 drives the slide bar 26 to move toward the outside of the fixed cylinder 25, thereby driving the guide plate 8 to rotate with its top as the center, so that the guide plate 8 is in an inclined state. When the stirring mechanism drives the raw material to rotate counterclockwise, the raw material in the top area will enter the filter frame 6 along the guide plate 8, thereby increasing the range of raw material filtration and impurity removal, and improving the adequacy of impurity cleaning; When the filter frame 6 moves upward, it drives the guide plate 8 to move upward synchronously. When the guide plate 8 abuts against the lower edge of the opening 5, the guide plate 8 gradually rotates to a vertical state and enters the interior of the opening 5.

[0023] A suction pipe 24 is installed on the outer wall of the other side of the fermentation tank 1. A control valve is installed on the suction pipe 24. The suction pipe 24 is located on the top of the linkage disk 4 and is connected to the dust collection equipment. After the impurities on the top of the linkage disk 4 are thrown to the edge of the linkage disk 4, the impurities on the edge of the linkage disk 4 are sucked away through the impurity extraction pipe 24.

[0024] A probiotic-based grain fermentation method, which uses the above-mentioned probiotic-based grain fermentation device, comprises the following steps: S1, adding raw materials required for fermentation into the fermentation tank 1 through the feeding cylinder 9; S2. The first motor 16 is controlled to drive the linkage shaft 12 to rotate counterclockwise, and the second transmission shaft 13 rotates synchronously therewith, thereby driving the stirring blades 14 to stir the raw materials inside the fermentation tank 1, wherein the lighter impurities float up; S3, by controlling the second motor 17 to drive the driving gear 19 to rotate counterclockwise, the driving gear 19 is meshed with the second one-way gear 23, and the driven shaft 20 is driven to rotate. When the driven shaft 20 rotates, the reciprocating screw 21 is driven to rotate synchronously, and the lifting block 22 is driven to move from the top end of the reciprocating screw 21 to the bottom end thereof, thereby driving the sliding sleeve 3 to move downward synchronously along the outer wall of the first transmission shaft 2, and each filter frame 6 is moved downward along the inner wall of the through port 5, so that the lower edge of the filter frame 6 moves down below the liquid level, and the upper edge of the filter frame 6 is positioned below the liquid level. Above the liquid level, at the same time, after the guide plate 8 moves out of the interior of the through port 5, the rebound force of the spring 27 drives the slide bar 26 to move toward the outside of the fixed cylinder 25, thereby driving the guide plate 8 to rotate with its top as the center, so that the guide plate 8 is in an inclined state. When the stirring mechanism drives the raw material to rotate counterclockwise, the raw material in the top area will enter the interior of the filter frame 6 along the guide plate 8, thereby increasing the range of raw material filtration and impurity removal, and improving the adequacy of impurity cleaning. When impurities pass through the interior of the filter frame 6, the impurities are filtered into the interior of the filter frame 6 by the filter screen 7; S4, by controlling the second motor 17 to drive the reciprocating screw 21 to continue rotating, driving the lifting block 22 to move from the bottom end of the reciprocating screw 21 to its top end, thereby driving the filter frame 6 to move up and reset through the sliding sleeve 3, so that the inner wall of the bottom of the filter frame 6 and the top of the linkage disk 4 are at the same horizontal height, and then controlling the second motor 17 to drive the driving gear 19 to rotate clockwise, through the meshing effect between the driving gear 19 and the first one-way gear 18, driving the first transmission shaft 2 to rotate counterclockwise, thereby driving each filter frame 6 to rotate synchronously counterclockwise through the sliding sleeve 3, and through the reverse centrifugal force, the impurities filtered inside the filter frame 6 are discharged in the reverse direction to the top of the linkage disk 4. Since the bottom of the filter frame 6 is still inside the through port 5, the linkage disk 4 rotates accordingly. In this process, the impurities on the top of the linkage disk 4 are thrown to the edge of the linkage disk 4; S5, after the impurities on the top of the linkage disk 4 are thrown to the edge of the linkage disk 4, the impurities on the edge of the linkage disk 4 are sucked out through the impurity extraction pipe 24; S6. Repeat the operations of S3-S4 to process the floating impurities multiple times. After the fermentation is completed, control the solenoid valve 11 to open and discharge the materials in the fermentation tank 1 through the discharge pipe 10.
