[0015] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0016] Please refer to the following: Figures 1-6 The feeding device for the livestock and poultry manure biogas fermentation tank includes: a base 1, a crushing box 2, and a screw feeder 3. The crushing box 2 is fixedly installed on the top of the base 1. A top beam 7 is fixedly installed above the base 1 via four columns, and four connecting rods are fixedly installed at the bottom of the top beam 7. The ends of the four connecting rods are fixedly connected to the screw feeder 3. A first feed hopper 4 and a discharge bend 5 are fixedly installed on the screw feeder 3. A discharge port 17 is opened on the side of the crushing box 2 closest to the screw feeder 3. A guide channel steel 18 is fixedly installed on the outer wall of the side of the crushing box 2 closest to the screw feeder 3, matching the discharge port 17 and located above the first feed hopper 4. A microbial agent addition mechanism is located on the side of the crushing box 2 closest to the screw feeder 3, above the first feed hopper 4 and on one side of the guide channel steel 18. This ensures that the addition of microbial agent and the discharge of manure are not... They will interfere with each other; a reinforcing folding plate 8 is fixedly installed at the bottom of the top beam 7, and a central connecting pipe 9 is rotatably installed on the reinforcing folding plate 8. The bottom end of the discharge bend 5 extends to the central connecting pipe 9 and is rotatably connected to the inner wall of the central connecting pipe 9. A horizontal pipe 10 is fixedly installed at the bottom of the central connecting pipe 9. Multiple discharge nozzles 11 are fixedly installed at the bottom of the horizontal pipe 10. Furthermore, a rotary motor 12 is fixedly installed on one side of the reinforcing folding plate 8. A first spur gear 13 is fixedly sleeved on its output shaft and the central connecting pipe 9. The two first spur gears 13 mesh with each other. By running the rotary motor 12, the horizontal pipe 10 can be rotated, so that the manure can be evenly spread in the biogas fermentation tank. In order to make the manure more finely crushed, a crushing mechanism is provided in the crushing box 2. The crushing mechanism is used to crush the manure to prevent clogging and also to improve the subsequent fermentation effect.
[0017] In this embodiment, the aforementioned microbial agent addition mechanism includes a microbial agent tank 6 fixedly installed on the outer wall of the crushing box 2. A dispensing pipe 21 is fixedly installed at the bottom of the microbial agent tank 6. A flow valve is provided on the dispensing pipe 21 to control the amount of fermentation agent discharged, so as to adapt to fermentation work under different conditions.
[0018] In this embodiment, the aforementioned pulverizing mechanism includes two pulverizing shafts 15 rotatably mounted inside the pulverizing chamber 2, with the same-direction ends of the two pulverizing shafts 15 extending outside the pulverizing chamber 2. Pulverizing rollers 16 are fixedly sleeved on both pulverizing shafts 15, and the pulverizing rollers 16 are located inside the pulverizing chamber 2. The two pulverizing rollers 16 are adapted to each other. A pulverizing motor is fixedly mounted on one side of the outer wall of the pulverizing chamber 2, and its output shaft is fixedly connected to one end of one of the pulverizing shafts 15. A second sprocket is fixedly sleeved on both pulverizing shafts 15, and the two second sprockets mesh with each other. The second sprockets are located outside the pulverizing chamber 2. By operating the pulverizing motor, the two meshing second sprockets can drive the two pulverizing rollers 16 to rotate, thereby enabling the pulverization of feces.
[0019] In this embodiment, to prevent feces from clogging the crushing box 2, a second feed hopper 14 is fixedly installed on the top of the crushing box 2, and the bottom inner wall of the crushing box 2 gradually slopes downward toward the discharge port 17. A dredging shaft 19 is rotatably installed inside the crushing box 2, and a dredging roller 20 is fixedly sleeved on the dredging shaft 19. The dredging roller 20 is located on one side of the discharge port 17, and multiple dredging blades are fixedly installed on the dredging roller 20. A dredging motor is fixedly installed on one side of the outer wall of the crushing box 2, and its output shaft is fixedly connected to one end of the dredging shaft 19. By driving the dredging roller 20 to rotate through the dredging motor, the dredging blades can be used to stir and push the feces, preventing the feces from accumulating and clogging at the discharge port 17, and ensuring that the crushed feces can be continuously and stably discharged through the discharge port 17.
[0020] In this embodiment, in order to improve the stability of the rotation of the central connecting pipe 9, a reinforcing ring is fixedly sleeved on the central connecting pipe 9. Four stabilizing heads arranged in a ring array are fixedly installed at the bottom of the reinforcing ring. The bottom ends of the four stabilizing heads are all spherical and in contact with the reinforcing folding plate 8. This contact between the spherical end and the reinforcing folding plate 8 does not affect the rotation of the central connecting pipe 9, but also provides stable support for the central connecting pipe 9, preventing the central connecting pipe 9 from shaking or deviating during rotation, and ensuring that the discharge nozzle 11 can discharge material stably and evenly.
[0021] The working principle of the livestock and poultry manure biogas fermentation tank feeding device provided by this utility model is as follows: In this invention, the horizontally placed pipe 10 is located directly above the external biogas digester; Before feeding livestock and poultry manure, an appropriate amount of fermentation agent is added to the agent tank 6. Then, the livestock and poultry manure to be treated is fed into the crushing box 2 through the second feed hopper 14 fixed to the top of the crushing box 2. The second feed hopper 14 can expand the feed opening diameter to avoid the accumulation and blockage of manure during the feeding process. Then, the crushing mechanism in the crushing box 2 starts to work. One of the crushing shafts 15 is driven to rotate by the crushing motor. The crushing shaft 15 drives the other crushing shaft 15 to rotate in the opposite direction synchronously through two meshing second round gears. The two crushing rollers 16 rotate in the opposite direction, squeezing and shearing the fed livestock and poultry manure to break down the clumps of manure residue, long straw, etc. into fine particles, thus avoiding blockage in the subsequent conveying process due to manure clumps from the source. Then, the crushed manure is discharged through the discharge port 17. During the discharge process, the unclogging motor drives the unclogging shaft 19 to rotate, and the unclogging roller 20 rotates synchronously. Multiple unclogging blades on the unclogging roller 20 continuously stir and push the manure at the discharge port 17 to prevent the manure from accumulating and clogging at the discharge port 17, ensuring that the crushed manure can be continuously and stably discharged through the discharge port 17. The manure discharged from the discharge port 17 is guided to the first feed hopper 4 by the guide channel steel 18 and enters the screw conveyor 3 for screw conveying. When the manure enters the first feed hopper 4, the flow valve is opened, and the fermentation agent flows into the first feed hopper 4 through the medicine outlet pipe 21, so that the agent and manure can be initially mixed with the screw conveyor after entering the screw conveyor 3, laying a good foundation for the subsequent fermentation process, and avoiding the fermentation effect due to uneven addition of agent. Subsequently, the mixture of manure and microbial agent conveyed by the screw feeder 3 is discharged into the central connecting pipe 9 through the discharge bend 5, and finally enters the horizontal pipe 10. It is then discharged into the external biogas digester through the discharge nozzle 11. At the same time, the rotary motor 12 is started, and its output shaft drives the central connecting pipe 9 to rotate through two meshing first spur gears 13. The central connecting pipe 9 then drives the horizontal pipe 10, which is fixedly installed at its bottom, to rotate. The multiple discharge nozzles 11 fixedly installed at the bottom of the horizontal pipe 10 rotate synchronously with the horizontal pipe 10, distributing the mixture of manure and microbial agent evenly to different areas inside the biogas digester, avoiding local accumulation of the mixture in the digester, and greatly improving the uniformity of feeding.
[0022] Compared with related technologies, the feeding device for livestock and poultry manure biogas fermentation tank provided by this utility model has the following beneficial effects: I. This utility model expands the feed opening diameter through the second feed hopper 14, crushes the larger waste such as lumps, residues and straw in the manure by the crushing roller 16, prevents the accumulation of the discharge port 17 by the unblocking roller 20, and conveys the manure in a uniform compression manner by the screw feeder 3. In addition, the multiple discharge nozzles 11 reduce the discharge blockage and avoid material blockage problems throughout the process. Second, this utility model achieves uniform material discharge in the fermentation tank through the rotating horizontal pipe 10 and the discharge nozzle 11, preventing the manure from accumulating in one place and improving the uniformity of manure distribution. At the same time, the microbial agent addition mechanism precisely controls the amount, ensuring that the manure and microbial agent are mixed and fed in a uniform manner, thereby improving the degree of fermentation and the quality of fermentation.
