[0038] A support frame 13 is fixedly installed on the inner side of the upper end of the rotating seat 2, a guide column 15 is arranged through the middle position of the support frame 13, and a stirring shaft 14 is fixedly installed on the lower end of the guide column 15, and the upper end of the stirring shaft 14 is passed through the middle position of the movable plate 5 for rotation; a fixed stirring rod 18 is fixedly installed at an equal angle on the outer side of the stirring shaft 14, and a movable stirring rod 19 is telescopically and rotatably installed on the outer side of the fixed stirring rod 18; the transmission assembly includes a gear 4 fixedly installed on the output end of the motor 3, and tooth blocks 6 are evenly arranged on the outer wall of the upper end of the rotating seat 2, and the gear 4 and the tooth block 6 are meshingly connected.

[0039] The inner wall of the rotating seat 2 is evenly provided with a slide groove 201, and the outer wall of the movable plate 5 is evenly provided with a slider, and the slider of the side wall of the movable plate 5 is lifted and slid along the slide groove 201, and a first spring 501 is fixedly connected between the lower surface of the slider and the lower inner wall of the slide groove 201. During the rotation of the rotating seat 2, the movable plate 5 drives the rubber ring 9 to twist and restore, and the rubber ring 9 will drive the movable plate 5 to move downward elastically during the twisting process. The rubber ring 9 and the fermentation tank body 1 are coaxially arranged, and the outer diameter of the rubber ring 9 is smaller than the inner diameter of the fermentation tank body 1, and the fermentation tank body 1 is evenly provided with air holes 101, and the fermentation tank body 1 is promoted to exhaust and ventilate through the air holes 101 during the twisting process of the rubber ring 9.

[0040] A first ball 1301 is embedded in the inner side of the support frame 13, and a spiral first guide groove 16 is provided on the outer wall of the guide column 15, and the guide column 15 passes through the center of the support frame 13 for lifting and lowering adjustment, and during the lifting and lowering adjustment of the guide column 15, the first ball 1301 rolls along the first guide groove 16 to drive the guide column 15 to rotate synchronously, and the end of the movable stirring rod 19 close to the rubber ring 9 is an arc structure, and during the twisting process of the rubber ring 9, the movable stirring rod 19 is pushed to be telescopically adjusted on the outside of the fixed stirring rod 18, and a spiral second guide groove 1801 is provided on the outer wall of the fixed stirring rod 18, and at the same time, a second ball 1901 is embedded in the inner wall of the end of the movable stirring rod 19 close to the stirring shaft 14, and the second ball 1901 slides along the second guide groove 1801 during the telescopic adjustment of the fixed stirring rod 18 and the movable stirring rod 19, and an exhaust pipe 20 is evenly and vertically arranged on the movable stirring rod 19.

[0041] By adopting the above technical solution, materials are fed into the inner side of the rubber ring 9 through the feeding port 7, and then the sealing cover plate 8 is closed, so that the materials are fermented on the inner side of the rubber ring 9. When the materials need to be turned over, the motor 3 is started, so that the motor 3 drives the gear 4 to rotate back and forth. At this time, the gear 4 will be meshed and connected with the tooth block 6 on the outer side of the rotating seat 2, thereby driving the rotating seat 2 to rotate back and forth. At this time, the rotating seat 2 will drive the movable plate 5 to rotate back and forth synchronously, so that the movable plate 5 can reciprocate and twist the rubber ring 9. At this time, the material inside will be initially turned over during the twisting process of the rubber ring 9. At the same time, the twisting process of the rubber ring 9 will drive the movable plate 5 to slide elastically along the slide groove 201 on the inner side of the rotating seat 2. At this time, the movable plate 5 will drive the stirring shaft 14 to rotate synchronously. The first ball 1301 embedded in the inner wall of the support frame 13 will roll along the first guide groove 16, thereby driving the guide column 15 to rotate back and forth. At this time, the guide column 15 will drive the stirring shaft 14 to rotate synchronously. At this time, the fixed stirring rod 18 and the movable stirring rod 19 can turn the material. As the rubber ring 9 twists, its inner wall will approach and squeeze the movable stirring rod 19, so that the movable stirring rod 19 and the fixed stirring rod 18 can be telescopically adjusted. At the same time, the second ball 1901 embedded in the movable stirring rod 19 will slide along the second guide groove 1801, thereby driving the movable stirring rod 19 to rotate around the fixed stirring rod 18, thereby turning the material at multiple angles through the exhaust pipe 20.

[0042] Embodiment 2: The technical content disclosed in this embodiment is a further improvement on the basis of the above embodiment 1. It is inconvenient to fully cool down the inside of the material pile during the use of the existing microbial fertilizer fermentation tank, thereby affecting the fertilizer fermentation efficiency. In order to further solve this technical problem, this embodiment discloses the following technical content, such as Figure 5-Figure 8 As shown;

[0043] An air delivery assembly is provided on the stirring shaft 14 , the fixed stirring rod 18 and the movable stirring rod 19 ; the pressure relief assembly includes a pressure relief hole 10 opened on the movable plate 5 , and an inverted truncated cone-shaped sealing plug 11 is sealed in the pressure relief hole 10 , and a second spring 12 is connected between the sealing plug 11 and the movable plate 5 .

[0044] The gas delivery component includes an air channel 17 opened in the stirring shaft 14 and the guide column 15, and a film 21 is fixedly provided at one end of the fixed stirring rod 18 located on the inner side of the movable stirring rod 19, and the film 21 is installed on the inner wall of the movable stirring rod 19 by interference sliding, and a spring is connected between the film 21 and the inner wall of the movable stirring rod 19, and at the same time, an air delivery pipe 22 is installed through the fixed stirring rod 18 and the film 21, and the two ends of the air delivery pipe 22 are respectively connected to the air channel 17 and the inside of the movable stirring rod 19, and a one-way valve structure is provided in the exhaust pipe 20 and the air delivery pipe 22.

[0045] By adopting the above technical solution, when the temperature inside the pile is high, the motor 3 is started to make the rubber ring 9 twist back and forth, thereby adjusting the space between the fermentation tank body 1 and the rubber ring 9, so that the fermentation tank body 1 can exchange gas through the air hole 101 to achieve initial cooling. As the rubber ring 9 twists and squeezes the movable stirring rod 19, the fixed stirring rod 18 and the movable stirring rod 19 will be elastically adjusted to make the film 21 slide back and forth on the inner side of the movable stirring rod 19, so that the movable stirring rod 19 inhales the outer air through the air pipe 22 and the airway 17. The gas is blown to the material evenly through the exhaust pipe 20, so as to realize the blowing and cooling in the process of turning the pile. At the same time, the blown gas can aerate the material efficiently, and further provide the turning and cooling effect. When the air pressure inside the rubber ring 9 is too high, the sealing plug 11 can be elastically lifted and lowered to complete the opening of the pressure relief hole 10, so as to realize automatic pressure relief and exhaust. When discharging, the discharge pipe valve is opened and the rubber ring 9 is controlled to twist, so that the air pressure inside the rubber ring 9 can be increased, thereby squeezing the material out of the discharge pipe, thereby improving the discharge smoothness and avoiding blockage.
