Description

Technical Field

[0001] The invention relates to the field of fermentation bins, and in particular to a pig manure fermentation bin and a fermentation method thereof. Background Art

[0002] Pig manure has a fine texture and contains more organic matter and nitrogen, phosphorus and potassium nutrients. It decomposes slowly and is suitable for use as basal fertilizer. Under modern pig farming conditions, pig manure treatment is a key environmental protection technology, otherwise it will cause environmental pollution. After scientific treatment with fertilizer fermentation agents, pig manure can be fermented into high-quality organic fertilizer to achieve zero pollution, zero emissions and no odor. With the continuous advancement of science and technology, people's requirements for the ecological environment are getting higher and higher. Therefore, the treatment of pig manure is particularly important. Therefore, it is necessary to use a pig manure fermentation tank to treat pig manure.

[0003] Pig manure fermentation bins include rectangular pool-type fermentation bins, inclined bed-type fermentation bins, vertical cylindrical fermentation bins, etc. All are equipped with ventilation pipes, and some are also equipped with stirring or turning devices. The intermittent aerobic dynamic composting technology is characterized by the use of layered and uniform feeding and discharging methods. A layer of material is evenly discharged from the bottom of the fermentation bin every day, and a layer of material is evenly fed into the top every day. Layered fermentation is carried out, and the temperature in the fermentation bin is always controlled at a certain level, which promotes the reproduction of bacteria under optimal conditions. The newly added pig manure is quickly fermented and decomposed every day, and the mature pig manure at the bottom is output in time, which greatly shortens the fermentation cycle.

[0004] When using the existing vertical cylindrical fermentation bin, it is necessary to manually climb to the top of the fermentation bin to open the cover to facilitate the material elevator to pour pig manure into the fermentation bin. After pouring, the cover is closed manually. However, the manual opening and closing method is more troublesome, and the overall height of the fermentation bin is relatively high, and manual climbing is more dangerous. Summary of the invention

The gas generated during fermentation makes the interior of the fermentation bin body 1 in a negative pressure state, and the gas pushes down the cover plate 9; S5. When it is necessary to add pig manure to the fermentation bin body 1 again, the ventilation component is started, the ventilation component works, and the gas inside the fermentation bin body 1 is discharged through the exhaust pipe 12, and the discharged gas is purified by the purification component; S6, the pig manure at the bottom of the fermentation bin body 1 is precipitated, and the fermented pig manure is discharged through the discharge pipe 13.

[0042] The present invention works specifically as follows: when in use, pig manure is poured into the hopper 21, the first motor 22 works to drive the winding assembly to wind up, the winding assembly pulls the hopper 21 to move upward, the limiting rods 23 on both sides of the hopper slide on the inner walls of the limiting grooves 24, when the hopper 21 slides upward, the limiting rods 23 on both sides contact the moving block 6, thereby pushing the moving block 6 to slide upward, the moving block 6 slides upward to drive the end of the second pull rope 17 to move, the first clamping block 61 and the second clamping block 62 on both sides of the moving block 6 slide on the inner wall of the slide groove 31, when the moving block 6 continues to move upward for a distance, the second pull rope 17 is tightened, and the other end of the second pull rope 17 pulls the upper cover plate 7 to flip around the convex rod 74 as the center of the circle under the action of multiple sets of second fixed pulleys 54, When the upper cover 7 rotates, it will drive one end of the pull rod 71 to move, and the limiting slider 72 at the other end of the pull rod 71 slides inside the limiting block 10. When the limiting slider 72 slides, the first pull rope 73 is tightened, and the other end of the first pull rope 73 pulls the slide plate 29 to slide on the inner wall of the moving groove 25. When the upper cover 7 is turned over, the protruding rod 74 is driven to rotate, and the first clamping block 61 and the second clamping block 62 gradually slide from the inside of the sliding groove 31 to the inner wall of the upper inclined groove 32, so that the limiting rod 23 gradually does not contact the moving block 6. When the first clamping block 61 and the second clamping block 62 completely slide to the inner wall of the upper inclined groove 32, the limiting rod 23 is completely separated from the moving block 6. At this time, the rotation angle of the upper cover 7 is greater than 90 degrees, and the moving block 6 will fall and reset under the action of its own gravity; When the upper cover plate 7 rotates with the protruding rod 74 as the center, the upper cover plate 7 is flipped to drive the protruding rod 74 to rotate, and the rotation of the protruding rod 74 drives the first bevel gear 82 to rotate. When the first bevel gear 82 rotates, it drives the second bevel gear 83 to rotate. When the second bevel gear 83 rotates, it drives the movable rod 81 to rotate. When the movable rod 81 rotates, the second bevel gear at the other end drives the transmission rod 84 to rotate. When the transmission rod 84 rotates, it drives the pulley 85 to rotate. Under the action of the belt 86, it drives another set of pulleys 85 to rotate. When the pulley 85 rotates, it drives the installation rod 91 to rotate. The rotation of the installation rod 91 drives the lower cover plate 9 to rotate with the installation rod 91 as the center. When the lower cover plate 9 rotates, the feed hopper 16 is exposed, which facilitates the pig manure to enter the interior of the fermentation bin body 1 through the feed hopper 16. The rotation angle of the lower cover plate 9 is greater than 90°; The limiting rod 23 slides on the inner wall of the limiting groove 24. When the limiting rod 23 slides to the top of the inner wall of the limiting groove 24, the winding assembly continues to work and drives the hopper 21 to move upward. When the hopper 21 continues to move upward, the limiting rods 23 on both sides of the hopper 21 are on the inner wall of the limiting groove 24. Then, under the limiting action of the limiting groove 24, the hopper 21 is turned over (this is the specific working principle of the prior art, please refer to the single-bucket tipping bucket elevator), and the pig manure in the hopper 21 will enter the fermentation bin body 1 through the feed hopper 16. Then the hopper 21 is reset. When the hopper 21 is reset, the limiting rods 23 on both sides contact the movable rod 291, and the movable rod 291 moves downward. When the movable rod 291 moves downward, it will drive the slide plate 29 to move downward, and the slide plate 29 will drive The end of the first pull rope 73 moves, and the other end of the first pull rope 73 drives the limiting slider 72 to slide under the action of the first fixed pulley 28. When the limiting slider 72 slides, it pulls the pull rod 71, and the other end of the pull rod 71 pulls the upper cover plate 7. Then, after the upper cover plate 7 rotates 10°, the magnetic block 292 on one side of the slide plate 29 gradually slides from the vertical groove 26 to the inside of the guide groove 27. When the magnetic block 292 slides to the bottom end of the inner wall of the guide groove 27, the limiting rod 23 separates from the movable rod 291. At this time, the upper cover plate 7 is reset under the action of its own gravity, and the limiting slider 72 slides on the inner wall of the limiting block 10. The limiting slider 72 contacts the inner wall of the limiting block 10 and the top of the fermentation bin body 1, so that the upper cover plate 7 slides slowly and will not fall directly on the top of the feed hopper 16. The hopper 21 will continue to reset, and the moving block 6 will contact the top of the roller 41. At this time, the limit rods 23 on both sides of the hopper will contact the moving block 6. At this time, the upper cover plate 7 is attached to the top of the feed hopper 16, and the limit rod 23 moves downward to squeeze the moving block 6. The first block 61 and the second block 62 on both sides of the limit block 6 slide on the inner wall of the slide groove 31. When the movement position of the limit rod 23 is lower than the movable rod 55, the limit rod 23 continues to move downward. When the limit block 6 moves downward, it squeezes the roller 41, and the roller 41 is The wheel drives the through rod 42 to slide on the outer wall of the directional block 44, and at the same time, the roller 41 moves downward to squeeze the spring 43, and the first block 61 and the second block 62 slide from the chute 31 to the inner wall of the lower chute 33 (the second pull rope 17 is not tightened), and then the hopper 2 continues to reset. At this time, the limit rod 23 is separated from the moving block 6, and the roller 41 drives the moving block 6 to reset under the action of the spring 43, and the first block 61 and the second block 62 move from the inner wall of the lower chute 33 to the inner wall of the chute 31; When the upper cover plate 7 is closed, the upper cover plate 7 flips and drives the convex rod 74 to rotate. The rotation of the convex rod 74 drives the first bevel gear 82 to rotate. When the first bevel gear 82 rotates, it will drive the second bevel gear 83 to rotate. When the second bevel gear 83 rotates, it will drive the movable rod 81 to rotate. When the movable rod 81 rotates, the second bevel gear at the other end drives the transmission rod 84 to rotate. When the transmission rod 84 rotates, it will drive the pulley 85 to rotate. Under the action of the belt 86, it will drive another set of pulleys 85 to rotate. When the pulley 85 rotates, it will drive the installation rod 91 to rotate. The rotation of the installation rod 91 will drive the lower cover plate 9 to rotate with the installation rod 91 as the center of the circle. When the lower cover plate 9 rotates, the feed hopper 16 is closed. The lower cover plate 9 is larger than the bottom of the feed hopper 16. The gas generated by the fermentation of pig manure in the fermentation bin body 1 will lift the lower cover plate 9, so that the lower cover plate 19 is always attached to the bottom end of the inner wall of the fermentation bin body 1, and the lower cover plate 19 closes the bottom of the feed hopper 16.
