Description

Technical Field

[0001] This invention relates to the field of livestock and poultry breeding equipment technology, and specifically to an automatic manure degradation device for livestock and poultry breeding. Background Technology

[0002] Livestock and poultry farming refers to agricultural production activities involving the large-scale raising of livestock and poultry to obtain products such as meat, eggs, and milk. The farming process generates a large amount of manure, which can pollute the environment if not properly treated. Livestock and poultry manure degradation refers to the process of converting the organic matter in manure into stable humus or biogas through natural or artificial means, while simultaneously killing pathogens and parasite eggs. This achieves resource utilization of waste, reduces pollution to soil, water, and air, and promotes agricultural ecological cycles.

[0003] Currently, the common methods for manure degradation are static composting or mechanical turning and aeration. While static fermentation has a simple structure, the degradation of the material is uneven between the inner and outer layers, and the central area is prone to oxygen deficiency, resulting in a long fermentation cycle and unstable effects. When using turning and aeration, the turning structure is mostly fixed in a fixed trajectory or moves in one direction, and the turning rate is difficult to adapt to different pile volumes of manure material, easily leading to over-turning or under-turning of manure material, affecting the uniformity of turning and aeration degradation efficiency. In addition, the addition of degradation microbial compound agents is mostly done in a one-time or fixed-point manner, which cannot be matched with the amount of manure material and the turning process. Moreover, the agent cannot be evenly contacted with the material during addition, making it difficult for the agent to mix fully with the material, affecting the overall degradation efficiency of manure material. Summary of the Invention

[0004] In view of the above-mentioned shortcomings of the existing technology, the present invention provides an automatic manure degradation device for livestock and poultry farming, which can effectively solve the problems of fixed manure material turning and throwing method, poor uniformity, and uneven mixing of microbial agent addition method, which affect degradation efficiency.

[0005] To achieve the above objectives, the present invention provides the following technical solution: This invention provides an automatic manure degradation device for livestock and poultry farming, comprising: A degradation chamber, wherein an adaptive turning and throwing component is fixedly connected to the bottom surface of the degradation chamber; The adaptive turning and turning assembly includes a lower fixed frame fixedly connected to the bottom surface of the degradation chamber, an upper fixed frame fixedly connected to the top surface of the degradation chamber, a transition ring rotatably connected to the inner walls of the upper and lower fixed frames via sealed bearings, a rotating shaft rotatably connected to the bottom of the degradation chamber, a connecting frame fixedly connected between the inner side of the transition ring and the outer peripheral wall of the rotating shaft, two external pipes rotatably connected to the side wall of the transition ring via sealed bearings, two turning plates fixedly connected to the outer peripheral walls of the two external pipes, a self-rotating air blowing component fixedly connected to the inner wall of the upper fixed frame, and an auxiliary heating drive component fixedly installed on the upper end face of the degradation chamber.

The PLC controller, the plurality of rangefinders, the servo motor are electrically connected to an external power supply.

[0009] Furthermore, the microbial agent addition component includes an eccentric cam fixedly connected to the outer peripheral wall of the rotating shaft; two sliding rods are slidably connected through the upper side wall of the upper fixed frame; two liquid storage cylinders are fixedly connected to the top surface of the degradation tank; control pistons are slidably connected to the inner walls of the two liquid storage cylinders; the two sliding rods respectively penetrate the axial side walls of the two liquid storage cylinders, and the ends of the two sliding rods located inside the two liquid storage cylinders are fixedly connected to the two control pistons; the ends of the two sliding rods located inside the upper fixed frame are fixedly connected to a stop block; the two stop blocks are in contact with and slidably engaged with the eccentric cam; and a uniform spraying component is fixedly connected to the outer peripheral walls of the two liquid storage cylinders.

[0010] Furthermore, the microbial agent addition component also includes two abutment rings fixedly connected to the outer peripheral walls of the two slide rods, and a lateral support is fixedly connected to the upper position of the outer peripheral wall of the upper fixed frame. The two slide rods are respectively slidably engaged with the two lateral supports, and a pressure spring is fitted on the outer peripheral wall of each of the two slide rods.

[0011] Furthermore, the uniform spraying component includes a support shaft seat fixedly connected to the outer peripheral wall of the storage tank. A pin is rotatably connected to the bottom end of the support shaft seat. A spray nozzle is fixedly installed on the outer peripheral wall of the pin. The spray nozzle is connected to the storage tank through a telescopic hose. A storage tank is fixedly connected to the upper end face of the degradation box. The storage tank is connected to the storage tank through a connecting pipe. One-way valves are fixedly installed at the communication points between the connecting pipe, the telescopic hose, and the storage tank. An L-shaped bracket is fixedly connected to the abutment ring.

[0012] Furthermore, the top of the degradation box is provided with a feeding pipe, the circumferential side wall of the degradation box is provided with a discharge port, and a sealing plate is hinged to the outer circumferential wall of the degradation box at the discharge port.

[0013] The technical solution provided by this invention has the following advantages compared with the known prior art: This invention incorporates an adaptive turning and turning component. Several rangefinders monitor the height of the accumulated fecal material to determine its degradation rate. Upon detecting the height, the rangefinders transmit signals to a PLC controller. The PLC controller then controls a servo motor to continue operating and adjusts its output speed based on the monitoring signals from the rangefinders. During the revolution of the servo motor-driven shaft, external pipe, and turning plates, the external pipe simultaneously rotates around its own axis, driving the turning plates to uniformly turn and turn the fecal material. When the manure material is piled up to a high height, i.e., when the amount of manure material is large, several turning plates are driven to fully turn the manure material at a high revolution and rotation speed to ensure the uniformity of the turning. Conversely, when the manure material is piled up to a low height, i.e. when the amount of manure material is small, several turning plates are driven to gently turn the manure material at a slower revolution and rotation speed to avoid over-turning the manure material and to ensure the overall integrity of the manure material and the inoculant. Thus, the turning speed can be adaptively adjusted according to the amount of manure material to ensure the uniformity of the turning and the aeration degradation efficiency. This invention includes a self-rotating air blowing component and an auxiliary heating drive component. When several turning plates revolve and rotate to turn and throw the fecal material, the meshing transmission between the micro gear and the lower plane toothed ring drives the rotating rod to rotate rapidly, causing the impeller on the rotating rod to rotate synchronously. The rotation of the impeller accelerates and guides the airflow to flow towards the end of the external pipe, so that the air can be sprayed at a high speed through several air nozzles into the material layer that has just been loosened by the turning plates, thereby improving the uniformity and sufficiency of oxygen contact with the fecal material. At the same time, external air enters the heat preservation cylinder through several air inlets at the top of the heat preservation cylinder. The heat generated by the operation of the servo motor mixes with the external air and is pushed into the external pipe by the impeller to achieve auxiliary heating and drying of the fecal material. In this invention, a microbial agent addition component is provided. The rotating shaft drives the eccentric cam to rotate simultaneously, and periodically squeezes the blocks at the ends of the two slide rods. Under the pushing action of the eccentric cam and the reset action of the pressure spring, the slide rods and the control piston reciprocate within the storage cylinder, causing the microbial agent in the storage cylinder to be squeezed out and transported to the spray nozzle through the telescopic hose. Finally, the microbial agent is poured into the fecal material through the spray nozzle. When the amount of fecal material is large, the frequency of the reciprocating sliding of the control piston in the storage cylinder and the rate at which the spray nozzle adds microbial agent to the fecal material can be increased. Conversely, when the amount of fecal material is small, the rate at which the spray nozzle adds microbial agent to the fecal material can be slowed down to adapt to the turning and throwing rate of the fecal material by several turning plates, thereby improving the mixing uniformity of fecal material with different amounts of microbial agent. In this invention, a uniform spraying component is provided. When the slide bar reciprocates, it drives the L-shaped bracket to move horizontally back and forth through the abutment ring. Under the meshing transmission of the toothed plate and the rotating gear, the pin shaft is driven to swing back and forth within a certain angle, thereby driving the spray nozzle to swing back and forth left and right. This allows the microbial agent to be sprayed uniformly back and forth on the turning and throwing surface of the material, thereby fully mixing the microbial agent with the fecal material and improving the overall degradation efficiency of the fecal material.

[0018] The present invention will be further described below with reference to embodiments.

[0019] Example: Refer to Figures 1 to 9 An automatic manure degradation device for livestock and poultry farming, comprising: Degradation box 1, with a feed pipe 7 at the top and a discharge port 8 on the circumferential side wall. A sealing plate 9 is hinged to the outer circumferential wall of degradation box 1 at the discharge port 8. An adaptive turning and throwing component 2 is fixedly connected to the bottom surface of degradation box 1. The adaptive turning and turning component 2 includes a lower fixed frame 21 fixedly connected to the bottom surface of the degradation box 1, an upper fixed frame 22 fixedly connected to the top surface of the degradation box 1, and a transition ring 23 rotatably connected to the inner walls of the upper fixed frame 22 and the lower fixed frame 21 through a sealed bearing. The sealed bearing has a sealing rating of IP65 to prevent air leakage and intrusion of fecal dust. A rotating shaft 24 is rotatably connected to the bottom end of the degradation box 1. A connecting frame 25 is fixedly connected between the inner side of the transition ring 23 and the outer peripheral wall of the rotating shaft 24. Two external pipes 26 are rotatably connected to the side wall of the transition ring 23 through a sealed bearing. Two turning plates 27 are fixedly connected to the outer peripheral walls of the two external pipes 26. A self-rotating air-blowing component 3 is fixedly connected to the inner wall of the upper fixed frame 22. The self-rotating air-blowing component 3 includes several upper arc-shaped frames 31 fixedly connected to the inner wall of the upper fixed frame 22. The bottom ends of the several upper arc-shaped frames 31 are fixedly connected to upper flat toothed rings 32. The outer peripheral walls of the two external pipes 26 are both fixedly connected to transmission gears 33. The two transmission gears 33 mesh with the upper flat toothed rings 32 for transmission. Several lower arc-shaped frames 34 are fixedly connected to the inner wall of the lower fixed frame 21. The top ends of the several lower arc-shaped frames 34 are fixedly connected to lower flat toothed rings 35. The inner walls of the two external pipes 26 are rotatably connected to rotating rods 37 via annular brackets 36. Impellers 38 are fixedly connected to the outer circumferential walls of the two rotating rods 37. Micro gears 39 are fixedly connected to the ends of the two rotating rods 37 near the rotating shaft 24. The two micro gears 39 mesh with the lower plane toothed ring 35 for transmission. The self-rotating air blowing component 3 also includes several arc-shaped air holes 310 opened at the top of the degradation box 1. Several air nozzles 311 are fixedly connected to the circumferential side walls of the external pipes 26. The air nozzles 311 are set in a conical structure. Specifically, the edge of the impeller 38 is fitted and slidably engaged with the inner wall of the external pipe 26, the rotational speed of the impeller 38 is 3000-5000 r / min, the jet pressure of the jet nozzle 311 is 0.3-0.5 MPa, and the airflow velocity is ≥15 m / s, to ensure efficient oxygen penetration into the material layer; An auxiliary heating drive component 4 is fixedly installed on the upper surface of the degradation chamber 1. The auxiliary heating drive component 4 includes a servo motor 41 fixedly installed on the upper surface of the degradation chamber 1. The servo motor 41 is model 80DK-M07725. A heat preservation cylinder 42 is fixedly connected to the upper surface of the degradation chamber 1. Several air inlets 43 are opened at the top of the heat preservation cylinder 42. Several rangefinders 44 are fixedly installed on the inner top surface of the degradation chamber 1. A PLC controller 45 is fixedly installed on the outer peripheral wall of the degradation chamber 1. The PLC controller 45, several rangefinders 44, and servo motor 41 are electrically connected to an external power supply. Specifically, the insulation cylinder 42 uses a 10mm thick rock wool insulation layer with an insulation efficiency of ≥85%. The gap between the cylinder wall and the outer shell of the servo motor 41 is 5cm, forming a heat exchange channel. The auxiliary heating temperature is controlled at 30-45 degrees Celsius, which is suitable for the optimal range of bacterial agent activity. Specifically, the PLC controller 45 is an S7-200SMART model, and the rangefinder 44 is an ultrasonic rangefinder of model URM37. The rangefinder 44 is set with a stacking height threshold: when the amount of fecal material is large, i.e., the monitoring height is ≥50cm, the servo motor 41 outputs a speed of 1000-1500r / min; when the amount of fecal material is small, i.e., the monitoring height is <50cm, the speed is adjusted to 600-1000r / min, so as to achieve precise matching between the speed and the amount of material. After several rangefinders 44 detect the height of the accumulated fecal material, they transmit signals to the PLC controller 45. The PLC controller 45 controls the servo motor 41 to continue running and adjusts the output speed of the servo motor 41 according to the monitoring signals from the rangefinders 44. During the revolution of the rotating shaft 24, the external pipe 26, and the turning plate 27 driven by the servo motor 41, the meshing transmission between the upper flat gear ring 32 and the transmission gear 33 drives the external pipe 26 to rotate around its own axis while revolving around the rotating shaft 24, thereby driving the several turning plates 27 to evenly turn and throw the fecal material. When the height of the accumulated fecal material is high, that is, when the amount of fecal material is large, the servo motor 44 will continue to operate. When the servo motor 41 drives the rotating shaft 24 to rotate at a relatively fast speed, the several turning plates 27 can fully turn the manure material at a high revolution and rotation speed to ensure the uniformity of the manure material turning. Conversely, when the manure material is piled up at a low speed, i.e., when the amount of manure material is small, the servo motor 41 drives the rotating shaft 24 to rotate at a slower speed, so that the several turning plates 27 can gently turn the manure material at a slower revolution and rotation speed to avoid over-turning the manure material and ensure the overall integrity of the manure material and the inoculant. Thus, the turning speed can be adaptively adjusted according to the amount of manure material to ensure the uniformity of the manure turning and the aeration degradation efficiency. When the several turning plates 27 are rotating and revolving to turn over the manure material, the meshing transmission between the micro gear 39 and the lower plane toothed ring 35 drives the rotating rod 37 to rotate rapidly, so that the impeller 38 on the rotating rod 37 rotates synchronously. The rotation of the impeller 38 accelerates and guides the airflow to flow to the end of the external pipe 26, so that the air can be sprayed at a high speed through several jet nozzles 311 into the material layer that has just been loosened by the turning plates 27, thereby improving the uniformity and fullness of oxygen contact with the manure material. At the same time, the external air enters the heat preservation cylinder 42 through several air inlets 43 at the top of the heat preservation cylinder 42. The heat generated by the operation of the servo motor 41 mixes with the external air and is pushed into the external pipe 26 by the impeller 38 to achieve auxiliary heating and drying of the manure material. A microbial agent adding component 5 is fixedly connected to the upper part of the outer peripheral wall of the rotating shaft 24. The microbial agent adding component 5 includes an eccentric cam 51 fixedly connected to the outer peripheral wall of the rotating shaft 24. Two sliding rods 52 are slidably connected through the upper part of the side wall of the upper fixed frame 22. Two liquid storage cylinders 53 are fixedly connected to the top surface of the degradation tank 1. The inner walls of the two liquid storage cylinders 53 are sealed and slidably connected to control pistons 54. The two sliding rods 52 pass through the axial side walls of the two liquid storage cylinders 53 respectively, and the ends of the two sliding rods 52 inside the two liquid storage cylinders 53 are fixedly connected to the two control pistons 54 respectively. The two sliding rods 52 are located on the upper fixed frame 22. Each end of the frame 22 is fixedly connected with a stop block 55. The two stop blocks 55 are in contact with the eccentric cam 51 and slide in fit. The outer peripheral walls of the two liquid storage cylinders 53 are fixedly connected with a uniform spraying component 6. The bacterial agent addition component 5 also includes two abutment rings 56 fixedly connected to the outer peripheral walls of the two slide rods 52. A lateral support 57 is fixedly connected to the upper position of the outer peripheral wall of the upper fixed frame 22. The two slide rods 52 slide in fit with the two lateral supports 57 respectively. The outer peripheral walls of the two slide rods 52 are each fitted with a pressure spring 58. The two ends of the two pressure springs 58 are fixedly connected to the abutment ring 56 and the lateral support 57 respectively. Specifically, the spring constant of the pressure spring 58 is 20N / mm, the return stroke is 10-15mm, the reciprocating frequency of the slide bar 52 is synchronized with the rotation speed of the rotating shaft 24, 50-120 times / min, to ensure a stable rate of bacterial agent addition; The rotation of the rotating shaft 24 simultaneously drives the eccentric cam 51 to rotate, periodically squeezing the abutments 55 at the ends of the two slide rods 52. Under the pushing action of the eccentric cam 51 and the resetting action of the pressure spring 58, the slide rods 52 and the control piston 54 reciprocate within the storage cylinder 53. When the control piston 54 returns, the bacterial agent in the storage tank 65 is drawn into the storage cylinder 53 through the connecting pipe 66. When the control piston 54 advances, the bacterial agent in the storage cylinder 53 is forced out and transported to the spray nozzle 63 through the telescopic hose 64, ultimately allowing the bacterial agent to be poured into the fecal material through the spray nozzle 63. When the amount of material is large, the rotating shaft 24 rotates at a faster speed and drives several turning plates 27 to turn and throw the fecal material at a faster rate. At the same time, the rotating shaft 24 drives the eccentric cam 51 to rotate at a faster speed to increase the frequency of the control piston 54 sliding back and forth in the liquid storage cylinder 53 and the rate at which the spray nozzle 63 adds microbial agent to the fecal material. Conversely, when the amount of fecal material is small, the rotating shaft 24 rotates at a slower speed and the rate at which the spray nozzle 63 adds microbial agent to the fecal material slows down to match the turning and throwing rate of the several turning plates 27 on the fecal material and improve the uniformity of mixing fecal material and microbial agent with different amounts of material. The uniform spraying component 6 includes a support shaft seat 61 fixedly connected to the outer peripheral wall of the liquid storage cylinder 53. A pin 62 is rotatably connected to the bottom end of the support shaft seat 61. A spray nozzle 63 is fixedly installed on the outer peripheral wall of the pin 62. The spray nozzle 63 is connected to the liquid storage cylinder 53 through a telescopic hose 64. A liquid storage tank 65 is fixedly connected to the upper end face of the degradation box 1. The liquid storage tank 65 is connected to the liquid storage cylinder 53 through a connecting pipe 66. One-way valves are fixedly installed at the connection points between the connecting pipe 66, the telescopic hose 64 and the liquid storage cylinder 53. An L-shaped bracket 67 is fixedly connected to the abutment ring 56. A toothed plate 68 is fixedly connected to the end of the L-shaped bracket 67. A rotating gear 69 is fixedly connected to the end of the pin 62. The rotating gear 69 meshes with the toothed plate 68 for transmission. Specifically, the one-way valve is model H12W-16P. The one-way valve at the connection between the connecting pipe 66 and the liquid storage tank 53 only allows liquid to flow from the connecting pipe 66 to the liquid storage tank 53. The one-way valve at the connection between the telescopic hose 64 and the liquid storage tank 53 only allows liquid to flow from the liquid storage tank 53 to the telescopic hose 64. The backflow prevention pressure threshold of the one-way valve is 0.1MPa to ensure that the bacterial agent is transported in one direction without backflow and to ensure accurate addition. Specifically, the reciprocating swing angle of the pin 62 is ±30 degrees, corresponding to a spray radius of 30-50cm for the spray nozzle 63, ensuring the uniform mixing of the added microbial agent with the fecal material. When the slide bar 52 reciprocates, it drives the L-shaped bracket 67 to move horizontally back and forth through the abutment ring 56. Under the meshing transmission of the toothed plate 68 and the rotating gear 69, it drives the pin shaft 62 to swing back and forth within a certain angle, thereby driving the spray nozzle 63 to swing back and forth left and right. This allows the microbial agent to be sprayed evenly back and forth on the turning and throwing surface of the material, thereby making the microbial agent fully mixed with the fecal material and improving the overall degradation efficiency of the fecal material.

[0020] The working principle of this invention is as follows: In use, the fecal material to be degraded is fed into the degradation chamber 1 through the feed pipe 7. The servo motor 41 is controlled to run, driving the rotating shaft 24 to rotate. The rotating shaft 24 drives the adapter ring 23 and two external pipes 26 to rotate, as well as several tilting plates 27 to rotate. The tilting plates 27 smooth the fecal material in the degradation chamber 1. Several rangefinders 44 monitor and measure the accumulation height of the fecal material to obtain the degradation amount. After monitoring the accumulation height, the rangefinders 44 transmit signals to the PLC controller 45. The PLC controller 45 controls the servo motor 41 to continue running and adjusts the output speed of the servo motor 41 based on the monitoring signals from the rangefinders 44. The servo motor 41 drives the rotating shaft 24 and two external pipes 26 to rotate. During the revolution of the pipe 26 and the turning plate 27, the meshing transmission between the upper flat toothed ring 32 and the transmission gear 33 drives the outer pipe 26 to rotate around the rotating shaft 24 while rotating around its own axis, thereby driving the turning plates 27 to evenly turn and throw the fecal material. When the fecal material is piled up at a high height, i.e., when the amount of fecal material is large, the servo motor 41 drives the rotating shaft 24 to rotate at a faster speed, so that the turning plates 27 can fully turn and throw the fecal material at a higher revolution and rotation speed, ensuring the uniformity of the turning and throwing of the fecal material. Conversely, when the fecal material is piled up at a low height, i.e. when the amount of fecal material is small, the servo motor 41 drives the rotating shaft 24 to rotate at a slower speed, so that the turning plates 27 can gently turn and throw the fecal material at a slower revolution and rotation speed. When the several turning plates 27 are rotating around and rotating to turn the manure material, the meshing transmission between the micro gear 39 and the lower plane toothed ring 35 drives the rotating rod 37 to rotate rapidly, so that the impeller 38 on the rotating rod 37 rotates synchronously. The rotation of the impeller 38 accelerates and guides the airflow to flow to the end of the external pipe 26, so that the air can be sprayed at a high speed through several jet nozzles 311 into the material layer that has just been loosened by the turning plates 27, thereby improving the uniformity and fullness of oxygen contact with the manure material. At the same time, the external air enters the heat preservation cylinder 42 through several air inlets 43 at the top of the heat preservation cylinder 42. The heat generated by the operation of the servo motor 41 mixes with the external air and is pushed into the external pipe 26 by the impeller 38, thereby realizing the auxiliary heating and drying of the manure material. The rotation of the rotating shaft 24 simultaneously drives the eccentric cam 51 to rotate, periodically pressing the abutments 55 at the ends of the two slide rods 52. Under the pushing action of the eccentric cam 51 and the resetting action of the pressure spring 58, the slide rods 52 and the control piston 54 reciprocate within the storage cylinder 53. When the control piston 54 returns, the bacterial agent in the storage tank 65 is drawn into the storage cylinder 53 through the connecting pipe 66. When the control piston 54 advances, the bacterial agent in the storage cylinder 53 is forced out and transported to the spray nozzle 63 through the telescopic hose 64, ultimately allowing the bacterial agent to be poured onto the surface through the spray nozzle 63. When there is a large amount of fecal material, the rotating shaft 24 rotates at a faster speed and drives several turning plates 27 to turn and throw the fecal material at a faster rate. At the same time, the rotating shaft 24 drives the eccentric cam 51 to rotate at a faster speed to increase the frequency of the control piston 54 sliding back and forth in the liquid storage cylinder 53 and the rate at which the spray nozzle 63 adds microbial agent to the fecal material. Conversely, when there is a small amount of fecal material, the rotating shaft 24 rotates at a slower speed and the rate at which the spray nozzle 63 adds microbial agent to the fecal material slows down to match the turning and throwing rate of the fecal material by the several turning plates 27. When the slide bar 52 reciprocates, it drives the L-shaped bracket 67 to move horizontally back and forth through the abutment ring 56. Under the meshing transmission of the toothed plate 68 and the rotating gear 69, it drives the pin shaft 62 to swing back and forth within a certain angle, thereby driving the spray nozzle 63 to swing back and forth left and right, so that the microbial agent can be sprayed evenly back and forth on the turning and throwing surface of the material, so that the microbial agent and the manure material are fully mixed.
