Description

Technical Field

[0001] This invention relates to the field of sheep manure fermentation, and more particularly to a sheep manure fermentation tank and its fermentation method. Background Technology

[0002] Sheep manure is a versatile animal excrement. After fermentation, it becomes an excellent organic fertilizer that can improve soil quality, prevent soil compaction, and has significant economic value. However, if sheep manure is fermented directly without being crushed, it may not ferment properly. Incomplete fermentation can easily cause root burn and may also contain bacteria and insect eggs, making plants susceptible to pests and diseases.

[0003] Therefore, sheep manure needs to be crushed during fermentation. After crushing, the insufficiently crushed sheep manure needs to be manually removed and fed back in for further crushing, which prolongs the crushing time. In addition, manual sieving is required after crushing, which results in a large labor input and reduces the fermentation efficiency of sheep manure. Summary of the Invention

[0004] To address the technical problems of needing to manually remove insufficiently ground sheep manure after crushing and then feeding it back in for further crushing, which prolongs the crushing time and requires manual sieving after crushing, resulting in high labor input and reduced fermentation efficiency, this invention provides a sheep manure fermentation tank and its fermentation method.

[0005] The present invention is achieved by the following technical solution: a sheep manure fermentation tank, including a box body, with openings symmetrically opened on both sides of the box body, a fermentation cylinder inside the box body, a recycling mechanism inside the box body, support plates symmetrically installed on the top of the box body, a fixed seat above the box body, a feeding pipe at the bottom center of the fixed seat, a screening mechanism above the fermentation cylinder below the feeding pipe, the screening mechanism and the support plate being connected by a shaking mechanism, fixed plates at the top of the support plate symmetrically installed on both sides of the fixed seat, an mounting plate at the top of the support plate installed on one side of the fixed seat, a crushing cylinder rotatably installed inside the fixed seat, a feeding port opened on one side of the crushing cylinder, push plates evenly installed on the inner wall of the crushing cylinder, a screening hole evenly opened on the crushing cylinder, and a crushing mechanism inside the crushing cylinder; The crushing mechanism includes a through-hole set on the crushing cylinder and away from the feeding port. Two crushing rollers are meshed inside the crushing cylinder. One end of each crushing roller is fixedly connected to a rotating rod that passes through the through-hole. A slot is opened on one side of the fixed seat. The two rotating rods pass through the slot and are rotatably connected to the side wall of the mounting plate. A gear is fitted on each of the two rotating rods. The two gears are meshed. The crushing cylinder is connected to one of the gears through a rotator.

[0006] As a further improvement to the above solution, the rotator includes a dual-shaft motor mounted on one side of the mounting plate. One output shaft of the dual-shaft motor is connected to a second gear, which meshes with one of the first gears. Connecting rods that penetrate the slot are symmetrically installed on the outer wall of the crushing cylinder. The two connecting rods are connected by a gear ring, which meshes with the second gear. The other output shaft of the dual-shaft motor is connected to the screening mechanism by a push assembly.

[0007] As a further improvement to the above solution, the screening mechanism includes an outer cylinder located below the feeding pipe.

The slide rods are connected to the shaking mechanism, and the slide rods are connected to the support plate through a locking member. An opening is provided at the bottom of the outer cylinder, and an inner cylinder is provided inside the outer cylinder. Screening holes are provided at equal intervals on the outer wall of the inner cylinder. Rotary shafts extending to the outside of the outer cylinder are fixedly connected to both sides of the inner cylinder, and one of the rotating shafts is connected to the recycling mechanism.

[0008] As a further improvement to the above solution, the shaking mechanism includes symmetrically opened sliding openings on the support plate, a stabilizing rod fixed inside the sliding opening, a sliding rod passing through the sliding opening and sleeved on the outside of the stabilizing rod, and a spring connected to the side wall of the sliding rod sleeved on the outside of the stabilizing rod.

[0009] As a further improvement to the above solution, the pushing assembly includes a rotating shaft connected to another output shaft of the dual-axis motor. The outer wall of the rotating shaft is provided with threaded holes one and two at equal intervals. Threaded hole two is located on one side of threaded hole two. A sleeve is fitted around the outside of the rotating shaft. A locking block is symmetrically installed on both sides of one end of the rotating shaft. A locking groove is symmetrically opened on the inner wall of the sleeve. The locking block extends into the inside of the locking groove and slides inside the locking groove. The rotating shaft and the sleeve are connected by bolts. Cam one and cam two are fitted around the outer wall of the sleeve. Cam one is located on one side of cam two. The long ends of the outer walls of cam one and cam two are slidably connected to the top of the push plate.

[0010] As a further improvement to the above solution, the recycling mechanism includes a pushing and flipping component and an accelerating collection group. The pushing and flipping component includes a gear three sleeved on the outside of one of the rotating shafts. An electric push rod is fixed to the inner wall of the housing. The output shaft of the electric push rod is connected to a moving rod. A toothed plate is installed at the top of the moving rod. The toothed plate is meshed with the gear three. A moving plate is connected to the bottom of the moving rod. An accelerating collection group is installed on the moving plate.

[0011] As a further improvement to the above solution, the accelerated moving collection group includes a mounting rod fixed to the bottom end of the moving plate, a gear four rotatably mounted on the mounting rod, a toothed plate two fixed to one side of the box and meshing with the top of the gear four, a groove opened on one side of the box, a collection plate located below the moving plate inserted inside the groove, a fixing rod fixed to the top of the collection plate, a T-shaped rod connected to the top of the fixing rod, a T-shaped groove opened at the bottom end of the moving plate, the T-shaped rod slidably installed inside the T-shaped groove, and a toothed plate three fixed to one side of the collection plate and meshing with the bottom end of the gear four.

[0012] As a further improvement to the above solution, a plug-in plate is fixedly connected to the inner wall of the groove, and a plug-in slot is opened on the collecting plate, with the plug-in plate inserted inside the plug-in slot.

[0013] As a further improvement to the above solution, the locking component includes a magnetic base installed at the bottom of the side wall of the support plate, and a magnetic sheet connected to the magnetic base is fixedly connected to the bottom end of the slide rod.

[0014] The present invention also provides a fermentation method for a sheep manure fermentation tank, comprising the sheep manure fermentation tank as described above, and including the following steps: Step 1: The staff puts the sheep manure to be fermented into the upper part of the two crushing rollers through the feeding port, and moves the sleeve so that the sleeve drives the groove to slide outside the clamping block, and the sleeve slides outside the rotating shaft, thereby moving the cam one to the top of the push plate, and installing bolts on the outside of the sleeve so that the bolts are inserted into the inside of the threaded hole two. Step 2: Start the dual-shaft motor. The dual-shaft motor will drive gear 2 to rotate. Through the meshing connection between gear 2 and one of gears 1, gear 1 will rotate. Through the meshing connection between the two gears 1, the other gear 1 will rotate in the opposite direction. In turn, the two gears 1 will drive the crushing roller to rotate, so that the two crushing rollers can crush the sheep manure. Step 3: The crushed sheep manure will fall to the bottom of the crushing drum and be screened through the first screening hole. The sheep manure that passes through the first screening hole will fall into the screening mechanism through the feeding pipe to achieve the initial screening of the sheep manure. The sheep manure that does not pass through the first screening hole will be located in the crushing drum. Step 4: Simultaneously, through the meshing connection between gear 2 and the gear ring, the gear ring will rotate, which will drive the connecting rod to rotate in the slot. In turn, the T-shaped rod will drive the crushing cylinder to rotate, and the crushing cylinder will drive the pusher plate to rotate synchronously. In turn, the pusher plate will move the incompletely crushed sheep manure to the top of the two crushing rollers, so that the crushing rollers can crush the sheep manure again. This will facilitate the initial screening of all the sheep manure inside the crushing cylinder and its entry into the screening mechanism. Step 5: The sheep manure passing through screening hole one will fall into the inner cylinder. The sheep manure will be screened through screening hole two, so that the sheep manure enters the fermentation cylinder. At the same time, the dual-shaft motor will drive the rotating shaft to rotate, which will drive the sleeve to rotate. The sleeve will drive cam one and cam two to rotate synchronously. Then, when the long end of cam one approaches the push plate, cam one will push the push plate to move down. Step Six: The push plate will cause the outer cylinder to move down, the outer cylinder will cause the slide rod to move down, and at the same time the outer cylinder will cause the inner cylinder to move down synchronously. Then the slide rod will slide on the stabilizer rod and compress the spring. When the long end of cam one moves up, it will cause cam one to disengage from the push plate. Step 7: Then, under the reverse force of the spring, the slide rod will move the outer cylinder upward, the outer cylinder will move the inner cylinder upward, and the inner cylinder will shake the sheep manure inside, which will help to speed up the screening of the sheep manure through the screening hole 2, and thus speed up the process of the sheep manure inside the inner cylinder falling into the fermentation tank for collection. Step 8: After the sheep manure screening is completed, the sheep manure larger than the diameter of the screening hole 2 will be located in the inner cylinder. Then, the worker disconnects the bolt from the threaded hole 2 and moves the sleeve outside the rotating shaft, so that the cam 2 moves directly above the push plate and the bolt extends into the threaded hole 1, thus fixing the sleeve to the rotating shaft. Step 9: The dual-axis motor will drive the second cam to rotate. When the long end of the second cam rotates downward, the second cam will push the push plate to move down, and the push plate will drive the outer cylinder and the inner cylinder to move down synchronously. At the same time, the outer cylinder will drive the slide rod to move down, and the slide rod will drive the magnetic sheet to move down. Since the length of the second cam is greater than the length of the first cam, the magnetic sheet will move onto the magnetic base, realizing the magnetic sheet and the magnetic base to be attracted and connected. Step 10: At the same time, the inner cylinder will drive the rotating shaft to move down, and the rotating shaft will drive the gear three to move down synchronously, and make the gear three mesh with the gear plate one. Through the adsorption and fixation of the magnetic sheet and the magnetic seat, the meshing stability of the gear three and the gear plate one is effectively maintained. Step 11: Next, start the electric push rod. The electric push rod will drive the moving rod to move, and the moving rod will drive the toothed plate to move. Through the meshing connection between the toothed plate and the gear three, the gear three will rotate. The gear three will drive the rotating shaft to rotate, and the rotating shaft will cause the inner cylinder to flip inside the outer cylinder, making it easier to pour out the sheep manure that has not passed the screening inside the inner cylinder. Step 12: Simultaneously, the moving rod will drive the moving plate to move, the moving plate will drive the mounting rod and gear four to move synchronously, and the moving plate will drive the fixed rod to move synchronously through the connection of the T-shaped rod and T-shaped groove, and the fixed rod will drive the collecting plate to move synchronously. Step 13: Through the meshing connection between gear four and toothed plate two, gear four will rotate. Through the meshing connection between gear four and toothed plate three, toothed plate three will move, and toothed plate three will drive the collecting plate to move. Step Fourteen: The collecting plate will slide inside the T-shaped groove via the fixed rod, thereby accelerating the movement speed of the collecting plate. This speed will be greater than that of the moving plate, making it easier for the collecting plate to slide outside the insertion groove. This will speed up the movement of the collecting plate to the bottom of the opening, allowing the inner cylinder to collect the unscreened sheep manure in the collecting plate when it is turned over, thus achieving the recycling of sheep manure.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. This invention, through a box, opening, fermentation cylinder, support plate, fixed seat, feeding pipe, fixed plate, mounting plate, crushing cylinder, pusher plate, and crushing mechanism, facilitates the crushing operation of sheep manure. Simultaneously, the rotation of the crushing cylinder and pusher plate moves the incompletely crushed sheep manure above the two crushing rollers, facilitating thorough crushing. This allows all the sheep manure to pass through preliminary screening and enter the screening mechanism, effectively facilitating further screening and fermentation. Furthermore, this design avoids the need to remove and re-add incompletely crushed sheep manure, effectively shortening the crushing time and improving the efficiency of thorough crushing. 2. The combined design of the screening and shaking mechanisms facilitates the shaking and screening of sheep manure inside, effectively accelerating the screening efficiency and thus speeding up the fermentation process of the sheep manure. 3. The design of the push-turning component and the accelerated movement collection group makes it easy for the inner cylinder to turn over the remaining sheep manure inside, so that the remaining sheep manure can be poured into the collection plate for collection, which facilitates the recycling of the remaining sheep manure inside the inner cylinder. In this way, this design avoids manual recycling of sheep manure, effectively reduces labor input, and facilitates sheep manure fermentation. Attached Figure Description

[0018] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0019] Example

[0020] Please combine Figures 1 to 8 This embodiment of a sheep manure fermentation tank includes a box body 1, with openings 2 symmetrically opened on both sides of the box body 1. A fermentation cylinder 3 is provided inside the box body 1, and a recycling mechanism is provided inside the box body 1. A support plate 4 is symmetrically installed on the top of the box body 1. A fixed seat 5 is provided above the box body 1. A feeding pipe 6 is provided at the middle of the bottom end of the fixed seat 5. A screening mechanism is provided below the feeding pipe 6 and located above the fermentation cylinder 3. The screening mechanism is connected to the support plate 4 through a shaking mechanism. Fixed plates 7 located at the top of the support plate 4 are symmetrically installed on both sides of the fixed seat 5. An installation plate 8 located at the top of the support plate 4 is installed on one side of the fixed seat 5. A crushing cylinder 9 is rotatably installed inside the fixed seat 5. A feeding port 12 is opened on one side of the crushing cylinder 9. Pushing plates 56 are installed at equal intervals on the inner wall of the crushing cylinder 9. Screening holes 13 are opened at equal intervals on the crushing cylinder 9. A crushing mechanism is provided inside the crushing cylinder 9. The crushing mechanism includes a through-hole 18 located on the crushing cylinder 9 and away from the feed port 12. Two crushing rollers 11 are meshed inside the crushing cylinder 9. One end of each crushing roller 11 is fixedly connected to a rotating rod 10 that passes through the through-hole 18. A slot 17 is provided on one side of the fixed base 5. The two rotating rods 10 pass through the slot 17 and are rotatably connected to the side wall of the mounting plate 8. Gear 15 is fitted on each of the two rotating rods 10. The two gear 15 are meshed together. The crushing cylinder 9 is connected to one of the gear 15 via a rotator. The rotator includes a dual-shaft motor 14 installed on one side of the mounting plate 8. One output shaft of the dual-shaft motor 14 is connected to a gear 2 16. The gear 2 16 is meshed with one of the gear 15. Connecting rods 19 that pass through the slot 17 are symmetrically installed on the outer wall of the crushing cylinder 9. The two connecting rods 19 are connected by a gear ring 20. The gear ring 20 is meshed with the gear 2 16. The other output shaft of the dual-shaft motor 14 is connected to the screening mechanism via a push assembly. Workers place the sheep manure to be fermented above the two crushing rollers 11 through the feeding port 12, and adjust the position of the pushing component so that cam 28 is directly above the push plate 40. Then, the dual-shaft motor 14 is started, which drives gear 16 to rotate. Through the meshing connection between gear 16 and one of gears 15, gear 15 will rotate. Through the meshing connection between the two gears 15, the other gear 15 will rotate in the opposite direction, thereby causing the two gears 15 to drive the crushing rollers 11 to rotate, facilitating the crushing operation of the two crushing rollers 11. The crushed sheep manure will fall to the bottom of the crushing cylinder 9 and be screened through the screening hole 13. The sheep manure that passes through the screening hole 13 falls into the screening mechanism through the feeding pipe 6, achieving preliminary screening of the sheep manure. The manure that does not pass through the screen is then screened. The sheep manure in the first hole 13 is located in the crushing cylinder 9. Simultaneously, through the meshing connection between the gear 16 and the gear ring 20, the gear ring 20 rotates. The gear ring 20 drives the connecting rod 19 to rotate in the slot 17, which in turn drives the crushing cylinder 9 to rotate. The crushing cylinder 9 drives the pusher plate 56 to rotate synchronously, which in turn moves the incompletely crushed sheep manure to the top of the two crushing rollers 11. This facilitates the crushing rollers 11 to crush the sheep manure again. This design facilitates repeated and thorough crushing of sheep manure, allowing all the sheep manure inside the crushing cylinder 9 to be preliminarily screened and enter the screening mechanism, thus providing convenience for further screening of sheep manure. At the same time, this design avoids the need to remove incompletely crushed sheep manure for re-feeding, shortening the crushing time of sheep manure and effectively improving the efficiency of thorough crushing of sheep manure.

[0021] The screening mechanism includes an outer cylinder 30 located below the feeding pipe 6. A push plate 40 is fixedly connected to the top of the outer wall of the outer cylinder 30. Slide rods 33 are fixedly connected to the top of both sides of the outer cylinder 30. The slide rods 33 are connected to the shaking mechanism and are connected to the support plate 4 by a locking member. An opening 35 is opened at the bottom of the outer cylinder 30. An inner cylinder 36 is provided inside the outer cylinder 30. Screening holes 37 are opened at equal intervals on the outer wall of the inner cylinder 36. Rotating shafts 38 extending to the outside of the outer cylinder 30 are fixedly connected to both sides of the inner cylinder 36. One of the rotating shafts 38 is connected to the recycling mechanism. The shaking mechanism includes sliding openings 31 symmetrically opened on the support plate 4. A stabilizing rod 32 is fixedly connected inside the sliding opening 31. The slide rod 33 passes through the sliding opening 31 and is sleeved on the outside of the stabilizing rod 32. A spring 34 connected to the side wall of the slide rod 33 is sleeved on the outside of the stabilizing rod 32. The locking member includes a spring 34 installed on the support plate 4. The magnetic base at the bottom of the side wall of the support plate 4, the bottom end of the slide rod 33 is fixed with a magnetic sheet connected to the magnetic base, the push assembly includes a rotating shaft 21 connected to another output shaft of the dual-axis motor 14, the outer wall of the rotating shaft 21 is provided with threaded holes 1 22 and 23 at equal intervals, the threaded hole 23 is located on one side of the threaded hole 23, the outer side of the rotating shaft 21 is fitted with a sleeve 24, the two sides of one end of the rotating shaft 21 are symmetrically installed with locking blocks 25, the inner wall of the sleeve 24 is symmetrically provided with locking grooves 26, the locking blocks 25 extend into the inside of the locking grooves 26, and the locking blocks 25 slide inside the locking grooves 26, the rotating shaft 21 and the sleeve 24 are connected by bolts 27, the outer wall of the sleeve 24 is fitted with cam 1 28 and cam 29, cam 1 28 is located on one side of cam 29, the long ends of the outer walls of cam 1 28 and cam 29 are slidably connected to the top end of the push plate 40; The operator moves the sleeve 24, causing the sleeve 24 to slide the slot 26 outside the locking block 25 and the sleeve 24 to slide outside the rotating shaft 21. This moves the cam 28 directly above the push plate 40. Then, a bolt 27 is installed on the outside of the sleeve 24, inserting it into the threaded hole 23. When sheep manure falls into the inner cylinder 36 through the screening hole 13, it is screened through the screening hole 37 and enters the fermentation cylinder 3. Simultaneously, the dual-shaft motor 14 drives the rotating shaft 21, which in turn drives the sleeve 24. The sleeve 24 then drives the cams 28 and 29 to rotate synchronously. When the long end of the cam 28 approaches the push plate 40, the cam 28 pushes the push plate. As the push plate 40 moves downward, the push plate 40 will drive the outer cylinder 30 to move downward, which in turn will drive the slide rod 33 to move downward. Simultaneously, the outer cylinder 30 will drive the inner cylinder 36 to move downward. The slide rod 33 will then slide on the stabilizing rod 32, compressing the spring 34. When the long end of the cam 28 moves upward, it will disengage from the push plate 40. Then, under the reverse force of the spring 34, the slide rod 33 will drive the outer cylinder 30 to move upward, which in turn will drive the inner cylinder 36 to move upward. This will cause the sheep manure inside the inner cylinder 36 to shake, facilitating faster screening of the sheep manure through the screening hole 37. This effectively improves the screening efficiency of the sheep manure and accelerates the collection of the sheep manure inside the inner cylinder 36 into the fermentation tank 3, thus speeding up the fermentation process of the sheep manure. After the sheep manure inside the inner cylinder 36 is screened, the sheep manure larger than the diameter of the screening hole 37 will be located in the inner cylinder 36. Then, the operator disconnects the bolt 27 from the threaded hole 23 and moves the sleeve 24 outside the rotating shaft 21, causing the cam 29 to move directly above the push plate 40. Then, the bolt 27 is extended into the threaded hole 22, fixing the sleeve 24 to the rotating shaft 21. The dual-shaft motor 14 will drive the cam 29 to rotate. When the long end of the cam 29 rotates downward, the cam 29 will push the push plate 40 downward, causing the push plate 40 to drive the outer cylinder 30 and the inner cylinder 36 to move downward synchronously. At the same time, the outer cylinder 30 will drive the slide rod 33 to move downward. The slide bar 33 will drive the magnetic sheet to move downwards. Since the length of cam 29 is greater than the length of cam 28, the magnetic sheet will move onto the magnetic base, achieving adsorption connection between the magnetic sheet and the magnetic base. At the same time, the inner cylinder 36 will drive the rotating shaft 38 to move downwards. The rotating shaft 38 will drive the gear 39 to move downwards synchronously, and the gear 39 will mesh with the toothed plate 43. Through the adsorption and fixation of the magnetic sheet and the magnetic base, the meshing stability of the gear 39 and the toothed plate 43 is effectively maintained, thus providing the possibility for the inner cylinder 36 to be turned over and dumped. At the same time, it provides convenience for the recycling of the remaining sheep manure inside the inner cylinder 36. Therefore, this design effectively avoids manual recycling of sheep manure, thereby reducing labor input.

[0022] The recycling mechanism includes a push-tilting component and an acceleration-moving collection assembly. The push-tilting component includes a gear 39 sleeved on the outside of one of the rotating shafts 38. An electric push rod 41 is fixed to the inner wall of the housing 1. The output shaft of the electric push rod 41 is connected to a moving rod 42. A toothed plate 43 is installed at the top of the moving rod 42 and meshes with the gear 39. A moving plate 44 is connected to the bottom of the moving rod 42. An acceleration-moving collection assembly is installed on the moving plate 44. The acceleration-moving collection assembly includes a mounting rod 45 fixed to the bottom of the moving plate 44. A gear 46 is rotatably mounted on the mounting rod 45. A gear 46 is fixed to one side of the housing 1. The gear plate 47 is meshed with the top of the gear 46. A groove 51 is provided on one side of the housing 1. A collection plate 52 located below the moving plate 44 is inserted inside the groove 51. A fixing rod 48 is fixedly connected to the top of the collection plate 52. A T-shaped rod 49 is connected to the top of the fixing rod 48. A T-shaped groove 50 is provided at the bottom of the moving plate 44. The T-shaped rod 49 is slidably installed inside the T-shaped groove 50. A gear plate 55 is fixedly connected to one side of the collection plate 52 and meshes with the bottom of the gear 46. A plug-in plate 53 is fixedly connected to the inner wall of the groove 51. A plug-in groove 54 is provided on the collection plate 52. The plug-in plate 53 is inserted inside the plug-in groove 54. After gear 39 meshes with gear plate 43, the electric push rod 41 is activated. The electric push rod 41 drives the moving rod 42 to move, which in turn drives gear plate 43 to move. Through the meshing connection between gear plate 43 and gear 39, gear 39 rotates, which in turn drives the rotating shaft 38 to rotate. The rotating shaft 38 causes the inner cylinder 36 to flip inside the outer cylinder 30, facilitating the removal of unscreened sheep manure from the inner cylinder 36. Simultaneously, the moving rod 42 drives the moving plate 44 to move, which in turn drives the mounting rod 45 and gear 46 to move synchronously. The moving plate 44, through the connection between the T-shaped rod 49 and the T-shaped groove 50, drives the fixed rod 48 to move synchronously. The fixed rod 48 then drives the collecting plate 52 to move synchronously, and through the meshing of gear 46 and gear plate 47... The engagement relationship causes gear 46 to rotate. Through the meshing connection between gear 46 and toothed plate 55, toothed plate 55 moves, which in turn drives collecting plate 52 to move. Collecting plate 52 then drives T-shaped rod 49 to slide inside T-shaped groove 50 via fixed rod 48, thereby accelerating the movement speed of collecting plate 52. This speed of collecting plate 52 is greater than that of moving plate 44, making it easier for collecting plate 52 to drive insertion groove 54 to slide outside insertion plate 53. This accelerates the movement of collecting plate 52 to below opening 35, allowing the inner cylinder 36 to collect unscreened sheep manure in collecting plate 52 during rotation, thus achieving sheep manure recycling. This avoids manual cleaning of inner cylinder 36, effectively reducing labor input and accelerating the fermentation process of sheep manure.

[0023] This embodiment provides a fermentation method for a sheep manure fermentation tank, comprising the sheep manure fermentation tank as described above, and including the following steps: Step 1: The staff puts the sheep manure to be fermented into the two crushing rollers 11 through the feeding port 12, and moves the sleeve 24 so that the sleeve 24 drives the slot 26 to slide outside the slot block 25, and the sleeve 24 slides outside the rotating shaft 21, thereby moving the cam 1 28 to the top of the push plate 40, and installing the bolt 27 on the outside of the sleeve 24 so that the bolt 27 is inserted into the threaded hole 23. Step 2: Start the dual-shaft motor 14. The dual-shaft motor 14 will drive the gear 2 16 to rotate. Through the meshing connection between the gear 2 16 and one of the gears 15, the gear 15 will rotate. Through the meshing connection between the two gears 15, the other gear 15 will rotate in the opposite direction. In turn, the two gears 15 will drive the crushing roller 11 to rotate, so that the two crushing rollers 11 can crush the sheep manure. Step 3: The crushed sheep manure will fall to the bottom of the crushing cylinder 9 and be screened through the screening hole 13. The sheep manure that passes through the screening hole 13 will fall into the screening mechanism through the feeding pipe 6 to achieve the initial screening of the sheep manure. The sheep manure that does not pass through the screening hole 13 will be located in the crushing cylinder 9. Step 4: Simultaneously, through the meshing connection between gear 26 and gear ring 20, gear ring 20 will rotate, which will drive connecting rod 19 to rotate in slot 17. In turn, connecting rod 19 will drive crushing cylinder 9 to rotate, and crushing cylinder 9 will drive pusher plate 56 to rotate synchronously. In turn, pusher plate 56 will move the incompletely crushed sheep manure to above the two crushing rollers 11, so that crushing rollers 11 can crush the sheep manure again, so that all the sheep manure inside crushing cylinder 9 can be preliminarily screened and enter the screening mechanism. Step 5: The sheep manure passing through the screening hole 13 will fall into the inner cylinder 36. The sheep manure will be screened through the screening hole 37 and enter the fermentation cylinder 3. At the same time, the dual-shaft motor 14 will drive the rotating shaft 21 to rotate. The rotating shaft 21 will drive the sleeve 24 to rotate. The sleeve 24 will drive the cam 28 and cam 29 to rotate synchronously. When the long end of the cam 28 approaches the push plate 40, the cam 28 will push the push plate 40 to move downward. Step 6: The push plate 40 will drive the outer cylinder 30 to move down, the outer cylinder 30 will drive the slide rod 33 to move down, and at the same time the outer cylinder 30 will drive the inner cylinder 36 to move down synchronously. As a result, the slide rod 33 will slide on the stabilizer rod 32 and compress the spring 34. When the long end of the cam 28 moves up, it will cause the cam 28 to disengage from the push plate 40. Step 7: Then, under the reverse force of the spring 34, the slide bar 33 will drive the outer cylinder 30 to move upward, the outer cylinder 30 will drive the inner cylinder 36 to move upward, and the inner cylinder 36 will cause the sheep manure inside to shake, so as to speed up the screening of the sheep manure through the screening hole 2 37, and thus speed up the sheep manure inside the inner cylinder 36 to fall into the fermentation tank 3 for collection. Step 8: After the sheep manure screening is completed, the sheep manure larger than the diameter of the screening hole 37 will be located in the inner cylinder 36. Then, the worker disconnects the bolt 27 from the threaded hole 23 and moves the sleeve 24 outside the rotating shaft 21, so that the cam 29 moves directly above the push plate 40 and the bolt 27 extends into the threaded hole 22, thereby fixing the sleeve 24 to the rotating shaft 21. Step 9: The operation of the dual-axis motor 14 will drive the second cam 29 to rotate. When the long end of the second cam 29 rotates downward, the second cam 29 will push the push plate 40 to move down, and the push plate 40 will drive the outer cylinder 30 and the inner cylinder 36 to move down synchronously. At the same time, the outer cylinder 30 will drive the slide rod 33 to move down, and the slide rod 33 will drive the magnetic sheet to move down. Since the length of the second cam 29 is greater than the length of the first cam 28, the magnetic sheet will move onto the magnetic base, realizing the magnetic sheet and the magnetic base adsorption connection. Step 10: At the same time, the inner cylinder 36 will drive the rotating shaft 38 to move down, and the rotating shaft 38 will drive the gear 39 to move down synchronously, and the gear 39 will mesh with the toothed plate 43. Through the adsorption and fixation of the magnetic sheet and the magnetic seat, the meshing stability of the gear 39 and the toothed plate 43 is effectively maintained. Step 11: Next, start the electric push rod 41. The electric push rod 41 will drive the moving rod 42 to move. The moving rod 42 will drive the toothed plate 43 to move. Through the meshing connection between the toothed plate 43 and the gear 39, the gear 39 will rotate. The gear 39 will drive the rotating shaft 38 to rotate. The rotating shaft 38 will cause the inner cylinder 36 to flip inside the outer cylinder 30, making it easier to pour out the sheep manure that has not passed the screening inside the inner cylinder 36. Step 12: Simultaneously, the moving rod 42 will drive the moving plate 44 to move, the moving plate 44 will drive the mounting rod 45 and gear 46 to move synchronously, and the moving plate 44 will drive the fixed rod 48 to move synchronously through the connection between the T-shaped rod 49 and the T-shaped groove 50, and the fixed rod 48 will drive the collecting plate 52 to move synchronously. Step 13: Through the meshing connection between gear 46 and toothed plate 2, gear 46 will rotate. Through the meshing connection between gear 46 and toothed plate 3, toothed plate 55 will move. Toothed plate 3 will drive the collecting plate 52 to move. Step Fourteen: The collecting plate 52 will drive the T-shaped rod 49 to slide inside the T-shaped groove 50 through the fixed rod 48, thereby accelerating the moving speed of the collecting plate 52. This makes the moving speed of the collecting plate 52 greater than that of the moving plate 44, which facilitates the collecting plate 52 to drive the insertion groove 54 to slide outside the insertion plate 53. This speeds up the movement of the collecting plate 52 to below the opening 35, making it easier for the inner cylinder 36 to collect the unscreened sheep manure in the collecting plate 52 when it is turned over, thus realizing the recycling of sheep manure.

6. A fermentation method for a sheep manure fermentation tank, comprising the sheep manure fermentation tank as described in claim 1, characterized in that: Includes the following steps: Step 1: The staff puts the sheep manure to be fermented into the upper part of the two crushing rollers through the feeding port, and moves the sleeve so that the sleeve drives the groove to slide outside the clamping block, and the sleeve slides outside the rotating shaft, thereby moving the cam one to the top of the push plate, and installing bolts on the outside of the sleeve so that the bolts are inserted into the inside of the threaded hole two. Step 2: Start the dual-shaft motor. The dual-shaft motor will drive gear 2 to rotate. Through the meshing connection between gear 2 and one of gears 1, gear 1 will rotate. Through the meshing connection between the two gears 1, the other gear 1 will rotate in the opposite direction. In turn, the two gears 1 will drive the crushing roller to rotate, so that the two crushing rollers can crush the sheep manure. Step 3: The crushed sheep manure will fall to the bottom of the crushing drum and be screened through the first screening hole. The sheep manure that passes through the first screening hole will fall into the screening mechanism through the feeding pipe to achieve the initial screening of the sheep manure. The sheep manure that does not pass through the first screening hole will be located in the crushing drum. Step 4: Simultaneously, through the meshing connection between gear 2 and the gear ring, the gear ring will rotate, which will drive the connecting rod to rotate in the slot. In turn, the connecting rod will drive the crushing cylinder to rotate, and the crushing cylinder will drive the pusher plate to rotate synchronously. In turn, the pusher plate will move the incompletely crushed sheep manure to the top of the two crushing rollers, so that the crushing rollers can crush the sheep manure again. This will facilitate the initial screening of all the sheep manure inside the crushing cylinder and its entry into the screening mechanism. Step 5: The sheep manure passing through screening hole one will fall into the inner cylinder. The sheep manure will be screened through screening hole two, so that the sheep manure enters the fermentation cylinder. At the same time, the dual-shaft motor will drive the rotating shaft to rotate, which will drive the sleeve to rotate. The sleeve will drive cam one and cam two to rotate synchronously. Then, when the long end of cam one approaches the push plate, cam one will push the push plate to move down. Step Six: The push plate will cause the outer cylinder to move down, the outer cylinder will cause the slide rod to move down, and at the same time the outer cylinder will cause the inner cylinder to move down synchronously. Then the slide rod will slide on the stabilizer rod and compress the spring. When the long end of cam one moves up, it will cause cam one to disengage from the push plate. Step 7: Then, under the reverse force of the spring, the slide rod will move the outer cylinder upward, the outer cylinder will move the inner cylinder upward, and the inner cylinder will shake the sheep manure inside, which will help to speed up the screening of the sheep manure through the screening hole 2, and thus speed up the process of the sheep manure inside the inner cylinder falling into the fermentation tank for collection. Step 8: After the sheep manure screening is completed, the sheep manure larger than the diameter of the screening hole 2 will be located in the inner cylinder. Then, the worker disconnects the bolt from the threaded hole 2 and moves the sleeve outside the rotating shaft, so that the cam 2 moves directly above the push plate and the bolt extends into the threaded hole 1, thus fixing the sleeve to the rotating shaft. Step 9: The dual-axis motor will drive the second cam to rotate. When the long end of the second cam rotates downward, the second cam will push the push plate to move down, and the push plate will drive the outer cylinder and the inner cylinder to move down synchronously. At the same time, the outer cylinder will drive the slide rod to move down, and the slide rod will drive the magnetic sheet to move down. Since the length of the second cam is greater than the length of the first cam, the magnetic sheet will move onto the magnetic base, realizing the magnetic sheet and the magnetic base to be attracted and connected. Step 10: At the same time, the inner cylinder will drive the rotating shaft to move down, and the rotating shaft will drive the gear three to move down synchronously, and make the gear three mesh with the gear plate one. Through the adsorption and fixation of the magnetic sheet and the magnetic seat, the meshing stability of the gear three and the gear plate one is effectively maintained. Step 11: Next, start the electric push rod. The electric push rod will drive the moving rod to move, and the moving rod will drive the toothed plate to move. Through the meshing connection between the toothed plate and the gear three, the gear three will rotate. The gear three will drive the rotating shaft to rotate, and the rotating shaft will cause the inner cylinder to flip inside the outer cylinder, making it easier to pour out the sheep manure that has not passed the screening inside the inner cylinder. Step 12: Simultaneously, the moving rod will drive the moving plate to move, the moving plate will drive the mounting rod and gear four to move synchronously, and the moving plate will drive the fixed rod to move synchronously through the connection of the T-shaped rod and T-shaped groove, and the fixed rod will drive the collecting plate to move synchronously. Step 13: Through the meshing connection between gear four and toothed plate two, gear four will rotate. Through the meshing connection between gear four and toothed plate three, toothed plate three will move, and toothed plate three will drive the collecting plate to move. Step Fourteen: The collecting plate will slide inside the T-shaped groove via the fixed rod, thereby accelerating the movement speed of the collecting plate. This speed will be greater than that of the moving plate, making it easier for the collecting plate to slide outside the insertion groove. This will speed up the movement of the collecting plate to the bottom of the opening, allowing the inner cylinder to collect the unscreened sheep manure in the collecting plate when it is turned over, thus achieving the recycling of sheep manure.
