[0013] The present invention has the following beneficial effects: (1) For the stable anaerobic fermentation device for breeding manure residue of the present invention, first place the manure residue into the fermentation tank. When in use, start the drive motor. The drive motor drives the rotation of the rotating shaft. Under the action of the two gears, the rotating shaft drives the reciprocating screw combination rod of the threaded rod to rotate. The reciprocating screw combination rod of the threaded rod drives the closing cover to descend. When the closing cover descends, the reciprocating screw combination rod of the threaded rod will also drive the hollow round block to reciprocate. During the movement of the hollow round block, it will drive the annular hollow block to rise. The annular hollow block will drive the hollow plate to rise. The hollow plate drives the two exhaust pipes to rise. The exhaust pipes drive the rectangular fixing plate to rise. The rectangular fixing plate will drive the rotating rod to move. The limiting wheel on the rotating rod will move along the inclined gap of the spiral inclined block during the rising of the rotating rod. Under the action of the gap of the spiral inclined block, the limiting wheel will rotate around the inner wall of the fermentation tank along the gap. As nitrogen gas enters through the nitrogen pipe, the nitrogen gas will be discharged from the hollow cavity, the hollow round block, the annular hollow block and the hollow plate and finally from the exhaust pipe. The nitrogen gas discharged from the exhaust pipe will turn over the manure residue in the fermentation tank with the rotation and lifting of the exhaust pipe and the hollow plate. The nitrogen gas will force out the oxygen from the gaps where the manure residue is turned over. (2) For the stable anaerobic fermentation device for breeding manure residue of the present invention, the discharged oxygen will be discharged into the air outlet box through a plurality of air outlet holes. As the gas increases, the gas in the air outlet box will push the pressure release plate to move away from the fermentation tank. At this time, the pressure release spring undergoes tensile deformation. After the pressure release plate passes through the pressure release groove, the oxygen will be discharged from the pressure release groove. During the movement of the hollow round block, the exhaust holes on the reciprocating screw combination rod of the threaded rod will continuously exhaust air into the hollow round block. The exhaust holes that do not contact the hollow round block will directly exhaust air into the fermentation tank to remove the oxygen in the fermentation tank. After the closing cover is closed on the fermentation tank, the oxygen in the fermentation tank will be completely removed. At this time, stop the input of nitrogen gas, and the pressure release spring will drive the pressure release plate to return to its original position under the action of elastic force. At this time, the air outlet box is in a closed state, preventing external air from entering the fermentation tank and affecting the fermentation work of anaerobic bacteria. (3) The present invention provides a stable anaerobic fermentation device for livestock manure. During the rotation of the rectangular fixed plate, the rectangular fixed plate drives a plurality of rotating rods to rotate along the hollow circular block. Since the fermentation box is full of manure, during the rotation of the rotating rod, the stirring blade on the rotating rod will contact the manure in the fermentation box. At this time, the stirring blade will rotate irregularly around the rotating rod under the action of the manure. During the rotation, the stirring blade will contact the manure, and the manure will pass through a plurality of extrusion grooves on the stirring blade. During the rotation of the stirring blade, the manure passing through the extrusion groove will be squeezed into strips and dispersed under the mechanical force of the rotation of the stirring blade. The extrusion will cause the manure in the fermentation box to be continuously stirred, fused and dispersed, so that the anaerobic bacteria in the fermentation box are fully dispersed, effectively improving the rate of anaerobic fermentation. (4) The present invention provides a stable anaerobic fermentation device for livestock manure residue. When the closing cover is lowered, it will drive a plurality of L-shaped ladder plates to descend. When the plurality of L-shaped ladder plates descend, they will contact a plurality of elastic plates on the outer wall of the fermentation box. When the L-shaped ladder plates contact the elastic plates, the elastic plates will descend and undergo elastic deformation. At this time, the closing cover will also leave the threads on the threaded rod reciprocating screw assembly rod. At this time, the rotation of the threaded rod reciprocating screw assembly rod will not affect the movement of the L-shaped ladder plates. The L-shaped ladder plates will always be in contact with the elastic plates and deformed. When the ladder plate squeezes the elastic plate, the elastic plate will drive the sealing plate to move toward the fermentation box, and the sealing plate will push the pressure release plate to move. At this time, the pressure release spring will be compressed and deformed, and the pressure release plate will leave the fixed plate. The methane produced by fermentation in the fermentation box will be discharged from the gap between the pressure release plate and the fixed plate. Since the sealing plate is in contact with the pressure release plate, the discharged methane will enter the annular collection box, and then the methane will be discharged from the outlet pipe for daily use, so that the methane can be used up in time to avoid the risk of explosion caused by excessive methane causing increased pressure in the fermentation box.

The hollow round block 105 is communicated with the annular hollow block 106, and a plurality of hollow plates 107 are fixedly installed on the top and bottom of the annular hollow block 106, respectively. The ends of the plurality of hollow plates 107 close to each other are communicated with the annular hollow block 106, and exhaust pipes 108 are fixedly installed on the side of the plurality of hollow plates 107 away from the threaded rod reciprocating screw combination rod 102, respectively. The plurality of exhaust pipes 108 are respectively communicated with the plurality of hollow plates 107, and a rectangular fixing plate 109 is fixedly installed on the ends of the corresponding two exhaust pipes 108 away from the threaded rod reciprocating screw combination rod 102.
[0020] like Figure 6 As shown, a limiting mechanism 2 is provided in the fermentation box 1, and the limiting mechanism 2 includes a plurality of spiral inclined blocks 201 fixedly mounted on the inner wall of the fermentation box 1, and a rotating rod 202 is fixedly mounted on the outer wall of the corresponding rectangular fixed plate 109, and the rotating rod 202 extends from one end of the threaded rod reciprocating screw combination rod 102 to the gap between the two spiral inclined blocks 201, and a limiting wheel 203 is rotatably sleeved on the rotating rod 202, and the limiting wheel 203 is adapted to the gap between the two rotating rods 202.
[0021] The hollow plate 107 drives the two exhaust pipes 108 to rise, and the exhaust pipes 108 drive the rectangular fixed plate 109 to rise. The rectangular fixed plate 109 drives the rotating rod 202 to move. The limiting wheel 203 on the rotating rod 202 moves along the oblique gap of the spiral inclined block 201 during the rising process of the rotating rod 202. Under the action of the gap of the spiral inclined block 201, the limiting wheel 203 will rotate around the inner wall of the fermentation box 1 along the gap.
[0022] like Figure 4 and Figure 6As shown, a stirring mechanism 3 is provided on a plurality of rectangular fixed plates 109, and the stirring mechanism 3 includes an annular fixed block 301 fixedly mounted on the inner wall of the plurality of rectangular fixed plates 109, a plurality of rotating rods 302 are rotatably mounted on the inner wall of the annular fixed block 301, and the ends of the plurality of rotating rods 302 close to each other are rotatably connected to the annular hollow block 106, and a plurality of stirring blades 303 are respectively fixedly sleeved on the plurality of rotating rods 302, and extrusion grooves 304 are respectively opened on the plurality of stirring blades 303.
[0023] During the rotation of the rotating rod 302, the stirring blade 303 on the rotating rod 302 will contact the feces residue in the fermentation box 1. At this time, the stirring blade 303 will rotate irregularly around the rotating rod 302 under the action of the feces residue. The stirring blade 303 will contact the feces residue during the rotation, and the feces residue will pass through a number of extrusion grooves 304 on the stirring blade 303. During the rotation of the stirring blade 303, the feces residue passing through the extrusion grooves 304 will be squeezed into strips and dispersed under the rotating mechanical force of the stirring blade 303. The extrusion will cause the feces residue in the fermentation box 1 to be continuously stirred, fused and dispersed, so that the anaerobic bacteria in the fermentation box 1 are fully dispersed, effectively improving the rate of anaerobic fermentation.
[0024] like Figure 7 As shown, a driving mechanism 4 is arranged on the mold frame 101, and the driving mechanism 4 includes a driving motor 402 fixedly mounted on the mold frame 101, and a rotating shaft 403 is fixedly mounted on the output shaft of the driving motor 402, and the rotating shaft 403 penetrates the mold frame 101 and is rotatably connected to the mold frame 101, and gears 404 are fixedly sleeved on the rotating shaft 403 and the threaded rod reciprocating screw combination rod 102 respectively, and the two gears 404 are meshed with each other, and a hollow block 405 is rotatably mounted on the top of the threaded rod reciprocating screw combination rod 102, and a nitrogen pipe 406 is fixedly mounted on the top of the hollow block 405.
[0025] When in use, the drive motor 402 is started, and the drive motor 402 drives the rotating shaft 403 to rotate. Under the action of the two gears 404, the rotating shaft 403 drives the threaded rod reciprocating screw combination rod 102 to rotate, and the threaded rod reciprocating screw combination rod 102 drives the closing cover 802 to descend.
[0026] like Figure 8 As shown, the fermentation box 1 is provided with a plurality of air outlet mechanisms 5, the air outlet mechanisms 5 include two rhombus-shaped grooves 501 opened on the fermentation box 1, a plurality of air outlet holes 502 are opened on the outer wall of the fermentation box 1, and an air outlet box 503 is fixedly installed on the outer wall of the fermentation box 1, and the air outlet box 503 covers the two rhombus-shaped grooves 501.
[0027] Since the feces residue in the fermentation box 1 is viscous and contains a small amount of water, the water will eventually return to the fermentation box 1 under the action of the inclined surface of the diamond groove 501 after passing through the air outlet 502, thereby preventing the water from entering the air outlet box 503.
[0028] like Figure 8 As shown, a plurality of pressure release mechanisms 6 are arranged on the outer wall of the fermentation box 1, and the pressure release mechanism 6 includes a pressure release spring 601 fixedly installed on the outer wall of the fermentation box 1, and a pressure release plate 602 is fixedly installed on the end of the pressure release spring 601 away from the fermentation box 1, and the pressure release plate 602 is slidably connected with the air outlet box 503, and a pressure release groove 603 is provided at the bottom of the air outlet box 503, and a fixing plate 604 is fixedly installed on the inner wall of the air outlet box 503 on the side away from the fermentation box 1, and the fixing plate 604 passes through the pressure release plate 602 and is slidably connected with the pressure release plate 602.
[0029] As the gas increases, the gas in the gas outlet box 503 will push the pressure release plate 602 to move away from the fermentation box 1. At this time, the pressure release spring 601 is stretched and deformed. After the pressure release plate 602 passes through the pressure release groove 603, oxygen will be discharged from the pressure release groove 603.
[0030] like Figure 8 As shown, a plurality of sealing mechanisms 7 are provided on the fermentation box 1, and the sealing mechanism 7 includes a sealing plate 701 slidably installed in the air outlet box 503, the side of the sealing plate 701 close to the fermentation box 1 is in contact with the pressure release plate 602, the side of the sealing plate 701 away from the fermentation box 1 extends to the outside of the air outlet box 503 and is slidably connected to the air outlet box 503, two sealing springs 702 are fixedly installed on the outer wall of the fermentation box 1, and an elastic plate 703 is fixedly installed on the side of the sealing plate 701 away from the fermentation box 1, and the ends of the two sealing springs 702 away from the fermentation box 1 are fixedly connected to the elastic plate 703.
[0031] The elastic plate 703 will drive the sealing plate 701 to move towards the fermentation box 1, and the sealing plate 701 will push the pressure release plate 602 to move. At this time, the pressure release spring 601 will be compressed and deformed. At this time, the pressure release plate 602 will leave the fixed plate 604, and the methane produced by fermentation in the fermentation box 1 will be discharged from the gap between the pressure release plate 602 and the fixed plate 604.
[0032] like Figure 1 , Figure 7 and Figure 8As shown in the figure, an adaptation mechanism 8 is provided at the bottom of the C-shaped frame 101. The adaptation mechanism 8 includes two sliding rods 801 fixedly installed at the bottom of the C-shaped frame 101. The bottom ends of the two sliding rods 801 are fixedly connected to the fermentation tank 1. A closing cover 802 is threadedly sleeved on the reciprocating screw combined rod 102 of the threaded rod. The two sliding rods 801 penetrate through the closing cover 802 and are slidably connected to the closing cover 802. A plurality of L-shaped ladder plates 803 are fixedly installed on the outer wall of the closing cover 802. An annular collection box 804 is fixedly installed on the outer wall of a plurality of air outlet boxes 503. A plurality of L-shaped ladder plates 803 communicate with the air outlet boxes 503. An air outlet pipe 805 is fixedly installed on the outer wall of the annular collection box 804.
[0033] When the closing cover 802 descends, it will drive a plurality of L-shaped ladder plates 803 to descend. The plurality of L-shaped ladder plates 803 will contact a plurality of elastic plates 703 on the outer wall of the fermentation tank 1 when descending. When the L-shaped ladder plate 803 contacts the elastic plate 703, the elastic plate 703 will descend and undergo elastic deformation. At this time, the closing cover 802 will also leave the thread on the reciprocating screw combined rod 102 of the threaded rod. At this time, the rotation of the reciprocating screw combined rod 102 of the threaded rod will not affect the movement of the L-shaped ladder plate 803. The L-shaped ladder plate 803 will always be in a state of contacting and deforming with the elastic plate 703. Since the sealing plate 701 is in contact with the pressure releasing plate 602, the discharged methane will enter the annular collection box 804, and then the methane will be discharged from the air outlet pipe 805 for domestic use, which can enable the methane to be used in time to avoid the risk of explosion due to excessive methane causing an increase in the pressure of the fermentation tank 1.
[0034] First, place the manure residue into the fermentation box 1, and start the driving motor 402 when in use. The driving motor 402 drives the rotating shaft 403 to rotate. Under the action of the two gears 404, the rotating shaft 403 drives the threaded rod reciprocating screw assembly rod 102 to rotate, and the threaded rod reciprocating screw assembly rod 102 drives the closing cover 802 to descend. When the closing cover 802 descends, the threaded rod reciprocating screw assembly rod 102 will also drive the hollow round block 105 to move back and forth. The hollow round block 105 will drive the annular hollow block 106 to rise during the movement, and the annular hollow block 106 will drive the hollow plate As the hollow plate 107 rises, the two exhaust pipes 108 rise, and the exhaust pipe 108 drives the rectangular fixed plate 109 to rise. The rectangular fixed plate 109 drives the rotating rod 202 to move. The limiting wheel 203 on the rotating rod 202 moves along the oblique gap of the spiral inclined block 201 during the rising process of the rotating rod 202. Under the action of the gap of the spiral inclined block 201, the limiting wheel 203 rotates around the inner wall of the fermentation box 1 along the gap. As the nitrogen enters the nitrogen pipe 406, the nitrogen will enter the hollow cavity 103, the hollow round block 105, the annular hollow block 106 and the hollow block 106. The core plate 107 is finally discharged from the exhaust pipe 108. The nitrogen discharged from the exhaust pipe 108 turns the feces in the fermentation box 1 as the exhaust pipe 108 and the hollow plate 107 rotate and rise and fall, and the nitrogen will force out the oxygen from the gaps in the turning of the feces; the discharged oxygen will be discharged into the air outlet box 503 from a plurality of air outlet holes 502. As the gas increases, the gas in the air outlet box 503 will push the pressure release plate 602 to move away from the fermentation box 1. At this time, the pressure release spring 601 is stretched and deformed. After the pressure release plate 602 passes through the pressure release groove 603, the oxygen will be discharged from the pressure release groove 60 3. During the movement of the hollow round block 105, the exhaust holes 104 on the threaded rod reciprocating screw rod assembly rod 102 will continue to exhaust air into the hollow round block 105, and the exhaust holes 104 that do not contact the hollow round block 105 will directly exhaust air into the fermentation box 1 to remove the oxygen in the fermentation box 1. After the closing cover 802 is closed on the fermentation box 1, the oxygen in the fermentation box 1 will be completely removed. At this time, the input of nitrogen is stopped, and the pressure release spring 601 will drive the pressure release plate 602 to return to its original position under the action of elastic force. At this time, the air outlet box 503 is in a closed state; During the rotation of the rectangular fixed plate 109, the rectangular fixed plate 109 will drive the plurality of rotating rods 302 to rotate along the hollow circular block 105. Since the fermentation box 1 is full of feces, during the rotation of the rotating rod 302, the stirring blades 303 on the rotating rods 302 will contact the feces in the fermentation box 1. At this time, the stirring blades 303 will rotate irregularly around the rotating rods 302 under the action of the feces. The stirring blades 303 will contact the feces during the rotation, and the feces will pass through the plurality of extrusion grooves 304 on the stirring blades 303. During the rotation of the stirring blades 303, the feces passing through the extrusion grooves 304 will be squeezed into strips and dispersed under the rotational mechanical force of the stirring blades 303. The extrusion will cause the feces in the fermentation box 1 to be continuously stirred, fused and dispersed. When the closing cover 802 descends, it will drive the plurality of L-shaped ladder plates 803 to descend. When the plurality of L-shaped ladder plates 803 descend, they will contact the plurality of elastic plates 703 on the outer wall of the fermentation box 1. When the L-shaped ladder plate 803 contacts the elastic plate 703, the elastic plate 703 will drop and deform elastically. At this time, the closing cover 802 will also leave the threads on the threaded rod reciprocating screw combination rod 102. At this time, the rotation of the threaded rod reciprocating screw combination rod 102 will not affect the movement of the L-shaped ladder plate 803. The L-shaped ladder plate 803 will always be in contact with and deformed with the elastic plate 703. When the L-shaped ladder plate 803 is squeezed onto the elastic plate 703, the elastic plate 703 will drive the sealing plate 703 to move. 01 moves toward the direction close to the fermentation box 1, the sealing plate 701 will push the pressure release plate 602 to move, and the pressure release spring 601 will be compressed and deformed. At this time, the pressure release plate 602 will leave the fixed plate 604, and the methane produced by fermentation in the fermentation box 1 will be discharged from the gap between the pressure release plate 602 and the fixed plate 604.
