Description

Technical Field

[0001] This invention relates to the field of chicken manure fermentation technology, specifically to a high-efficiency chicken manure fermentation equipment and method for livestock farms. Background Technology

[0002] To ensure the recyclability of resources, livestock manure needs to be collected and fermented in a centralized manner during livestock farming. Fermentation is a process in which microorganisms rapidly develop using the organic matter and residual protein in the manure under certain temperature, humidity and sufficient oxygen conditions. In order to ensure and improve nutrient supply during the aerobic fermentation process, the manure pile also needs to be turned over in a timely manner.

[0003] Chinese patent CN215209169U discloses a rapid fermentation device for poultry manure organic fertilizer, comprising a frame, on which a drive motor and drive wheels are connected to each other. The drive wheels are located at the left and right ends of the lower side of the frame, and the drive motor is located on the upper side of the frame. A support platform is also provided on the upper side of the frame. A slide rail is provided on the lower side of the frame, and a U-shaped plate is slidably connected to the slide rail. A slide rail is provided on the support platform, and a moving rod is provided in the slide rail. The upper end of the moving rod is located on the upper side of the support platform, and the lower end of the moving rod is connected to a seat located on the upper side of the U-shaped plate. A first telescopic rod is hinged to the lower side of the U-shaped plate, and the lower end of the first telescopic rod is hinged to the middle of a connecting plate. The upper side of the frame is hinged... The second telescopic rod is connected to the right side of the connecting plate at its lower end. Track support plates are provided on the front and rear sides of the connecting plate. The track support plates are provided with drive wheels and driven wheels, and tracks are provided on the drive wheels and driven wheels. The drive wheels can move on the fermentation tank. The drive wheels drive the nail-pulling plate to rotate. The nail-pulling plate turns over the material piled in the fermentation tank. Through rapid rotation, the material at the bottom of the fermentation tank is turned over onto the track support plate. The rapidly rotating track support plate continuously transports the material to the highest point of the turning track and throws it into the trough behind the moving direction to be neatly piled up again. The material is in full contact with air during the fermentation and turning process, thereby improving the oxygen supply in the re-piled material pile.

[0004] However, during the movement of the turning track, the contact between the turning track and the manure pile is unrestricted, resulting in uneven thickness of the manure pile when it comes into contact with the turning track. This leads to incomplete turning of the manure pile during the turning process, affecting the final turning effect. Summary of the Invention

[0018] S2. Prepare auxiliary materials: crush one or more of the following: straw, rice husks, sawdust, mushroom residue, and hay, with a total weight of 20%-30% of the chicken manure; prepare one or more of the following: brown sugar, wheat bran, and humic acid, with a total weight of 1%-5% of the chicken manure.

[0019] S3. Composting and fermentation: Mix the main materials and auxiliary materials, and pour the mixture into the fermentation tank. The pile should be 1.5m to 2m wide, 1m to 1.5m high, and the length should match the length of the fermentation tank.

[0020] S4. Fermentation maintenance: When the temperature exceeds 65℃ or begins to drop, use the turning conveyor and the blocking rod to turn the pile.

[0021] S5. Compost turning: The material blocking rod controls the compost to be evenly spread onto the turning conveyor, and the turning conveyor drives the compost to gradually complete the turning process.

[0022] S6, the maturation stage, fermentation lasts for 20-30 days until the pile temperature drops below 40℃, and the material is grayish-brown, loose and odorless.

[0023] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0024] 1. The farm uses high-efficiency chicken manure fermentation equipment and methods. By using a material blocking rod in conjunction with a turning conveyor belt, the turning conveyor belt is prevented from directly contacting the manure pile during the turning process. The material blocking rod controls the turning conveyor belt to gradually contact and transport the manure pile, thereby ensuring the uniformity of manure transport during the turning process. Furthermore, the material blocking rod adjusts the material flow to ensure the uniformity of manure turning, thus effectively guaranteeing the turning effect of the manure pile.

[0025] 2. This farm uses high-efficiency chicken manure fermentation equipment and methods. By using a flat shovel head to fit the bottom of the fermentation tank, the manure pile is prevented from sticking to the bottom of the tank, further improving the turning effect of the manure pile at the bottom. At the same time, during the turning process, the air pump pumps gas into the distribution chamber. The gas enters the interior of the vertical air chamber through the distribution chamber and the air guide pipe, and then is discharged through the air chamber. The continuous discharge airflow increases the gas flow inside the manure pile. The airflow inside the manure pile increases the looseness of the manure pile at the top of the flat shovel head, and further increases the contact effect between the manure pile at the top and oxygen, thereby preventing the manure pile from clumping. At the same time, it ensures the looseness of the manure pile after turning, ensuring the effect of composting and fermentation.

[0026] 3. The farm uses high-efficiency chicken manure fermentation equipment and methods. Through the combined action of the internal piston and the accumulating spring, high-pressure airflow is intermittently generated inside the inner cavity. This intermittent high-pressure airflow causes the main rod to vibrate intermittently, thus preventing the manure from getting stuck between the main rods during rotation. This ensures that the manure can stably pass through several main rods, guaranteeing the stability of the manure turning process. Furthermore, by controlling the vibration of the main rod during rotation, the manure is prevented from sticking to the main rod, further ensuring the smoothness of the manure turning process. At the same time, by accumulating pressure on the pumped airflow, the impact of the ejected airflow is ensured, improving the dispersing effect of the airflow on the manure. The fluctuating ejected airflow allows the manure to flow with the fluctuating high-pressure airflow, further ensuring the dispersing effect of the airflow on the manure.

[0027] 4. The farm uses high-efficiency chicken manure fermentation equipment and methods. High-pressure airflow is sprayed out through several air outlets at different positions inside the inner tube, thereby effectively increasing the spraying position of the high-pressure airflow and thus increasing the effect of the sprayed airflow on the manure pile. The high-pressure airflow sprayed at different positions further increases the effect of the sprayed airflow on the manure pile. This not only effectively avoids the manure pile from becoming blocked on the outside of the main body, but also further increases the contact between the manure pile and oxygen, ensuring the subsequent fermentation effect of the manure pile.

[0045] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0046] Example 1, please refer to Figures 1-2 , Figures 5-8 A high-efficiency fermentation device for chicken manure in a farm includes a movable base 3. The top of the movable base 3 is provided with a control platform 4 and a cantilever platform 5. The bottom of the cantilever platform 5 is provided with a turning track 6. The bottom front end of the turning track 6 is provided with a flat shovel head 9. The bottom front end of the cantilever platform 5 is provided with a plurality of material blocking rods 8. The top of the flat shovel head 9 is provided with a vertical air chamber 91. The ends of the material blocking rods 8 extend downward and are embedded in the vertical air chamber 91. The material blocking rods 8 include a material guide drive provided at the top end. The material blocking rods 8 are located in front of the turning track 6.

[0047] It also includes a fermentation tank 1, with guide rails 2 installed on both sides of the top of the fermentation tank 1. The movable base 3 travels on the top of the guide rails 2. The width of the turning track 6 is adapted to the width of the fermentation tank 1. The width of the fermentation tank 1 is 1.5m to 2m and the height is 1m to 1.5m. Several material blocking rods 8 are evenly distributed on the top of the turning track 6.

[0048] Fermentation tank 1 is built inside the chicken manure fermentation treatment shed, and the length of fermentation tank 1 is determined by the length of the shed.

[0049] During fermentation, a mixture of carbon and nitrogen auxiliary materials is added to the chicken manure to adjust the carbon-to-nitrogen ratio to 25-30:1. The mixed material is then piled inside fermentation tank 1, with a height of 1-1.5 meters, a width of 1.5-2 meters, and a length determined by the length of fermentation tank 1. Each layer of chicken manure is 20-30 cm thick. A mixture of inoculants is then sprinkled on top. In the initial stage, the mixture is covered with plastic film to maintain a temperature of 55-65℃ for 3-5 days for sterilization. When the temperature drops to 40℃, the pile is turned over for the first time, and then turned over every 2-3 days thereafter. Throughout the process, the humidity is maintained at 50-60%, which can be checked by inserting a bamboo pole.

[0050] During the turning process, the control mobile base 3 moves on top of the guide rail 2, causing the material blocking rod 8 and the turning track 6 to gradually contact the manure pile. When in contact with the manure pile, the material blocking rod 8 is located in front of the turning track 6 and contacts the manure pile first. The material guide drive drives the material blocking rod 8 to rotate. During the rotation of the material blocking rod 8, the manure pile is evenly dropped behind the material blocking rod 8 and then gradually contacts the turning track 6. The turning track 6 drives the manure pile to be evenly transported behind the turning track 6 and finally piled up behind the turning track 6, completing the turning operation of the manure fermentation.

[0051] By using the material blocking rod 8 in conjunction with the turning track 6, the turning track 6 is prevented from directly contacting the manure pile during the turning process. The material blocking rod 8 controls the turning track 6 to gradually contact and transport the manure pile, thereby ensuring the uniformity of manure transport during the turning process. Furthermore, the material blocking rod 8 adjusts the material flow to ensure the uniformity of manure turning, thus effectively guaranteeing the turning effect of the manure pile.

[0052] refer to Figure 8 In an optional embodiment, the material-turning track 6 includes an adjusting bracket 61, which is adjustablely mounted on the bottom of the cantilever platform 5. A guide track 62 is movably connected to the outside of the adjusting bracket 61. A drive system 63 for rotating the guide track 62 is provided inside the adjusting bracket 61. An air supply shaft pipe 64 is also provided inside the adjusting bracket 61. A connecting air pipe 65 is movably connected to the outside of the air supply shaft pipe 64. An air inlet 66 is provided at the outer end of the connecting air pipe 65. An air pump 7 is provided outside the air inlet 66 and is mounted on the top of the cantilever platform 5.

[0053] refer to Figure 7 A diversion chamber 93 is fixedly installed at the bottom of the flat shovel head 9. The diversion chamber 93 is connected to the air supply shaft pipe 64. Several air guide pipes 92 are provided on the outside of the diversion chamber 93. The air guide pipes 92 are connected to several vertical air chambers 91.

[0054] During the turning process, the flat shovel head 9 fits against the bottom of the fermentation tank 1, thus preventing the manure from sticking to the bottom of the tank and further improving the turning effect on the bottom of the manure. At the same time, during the turning process, the air pump 7 pumps gas into the diversion chamber 93. The gas enters the interior of the vertical air chamber 91 through the diversion chamber 93 and the air guide pipe 92, and then is discharged through the vertical air chamber 91. The continuous discharge of airflow increases the gas flow inside the manure pile. The airflow inside the manure pile increases the looseness of the manure pile at the top of the flat shovel head 9 and further increases the contact effect between the manure pile at the top and oxygen, thereby preventing the manure pile from clumping. At the same time, it ensures the looseness of the manure pile after turning, ensuring the effect of composting and fermentation.

[0055] refer to Figure 3In an optional embodiment, the material guide drive includes a drive box 81 fixedly connected to the bottom of the cantilever table 5. A main shaft 82 is rotatably connected inside the drive box 81. The material blocking rod 8 also includes a curtain rod 84, which is rotatably connected to the bottom of the drive box 81. A transmission gear set 83 is provided between the curtain rod 84 and the main shaft 82. A material guide motor is provided outside the main shaft 82.

[0056] When the material blocking rod 8 is working, the material guiding motor drives the main shaft 82 to rotate. The main shaft 82 drives several curtain rods 84 to rotate through the transmission gear set 83. The rotating curtain rods 84 drive the manure pile in contact with the curtain rods 84 to pass through, so that the manure pile can pass through the curtain rods 84 evenly and stably. This achieves the effect of adjusting and controlling the amount of manure pile contacted by the turning track 6, and ensures the stability of the turning track 6 in contacting and conveying the manure pile.

[0057] Example 2, Reference Figure 7 and Figure 9 Based on Embodiment 1, the curtain rod 84 further includes a main rod body 841 and a connecting sleeve 842. The connecting sleeve 842 extends into the interior of the drive box 81 and is connected to the transmission gear set 83. A reset spring 843 is provided between the connecting sleeve 842 and the main rod body 841. A limiting pin 844 is provided inside the main rod body 841 and engages with the connecting sleeve 842. A limiting spring 845 is provided between the limiting pin 844 and the main rod body 841. An inner cavity 846 is opened inside the main rod body 841. An inner piston 847 is slidably connected inside the inner cavity 846. A pressure accumulator spring 848 is provided between the inner piston 847 and the inner cavity 846. The main rod body 841 is inserted into the interior of the vertical air chamber 91. An air inlet is opened at the bottom end of the inner cavity 846 extending into the interior of the vertical air chamber 91.

[0058] When gas is pumped into the vertical air chamber 91, the gas enters the inner tube 846 through the air inlet. Inside the inner tube 846, the gas compresses the inner piston 847, which in turn compresses the accumulator spring 848. When the internal air pressure of the inner tube 846 exceeds the limiting force of the return spring 843 and the limiting pin 844 on the main rod 841, the limiting pin 844 disengages from the main rod 841 and the connecting sleeve 842. At this point, the internal air pressure of the inner tube 846 is greater than that of the return spring 843. The squeezing force of 43, under the action of air pressure, drives the main rod 841 to move upward. At the same time, the gas inside the inner tube 846 is discharged, and the air pressure inside the inner tube 846 decreases. Then, the pushing force of the return spring 843 on the main rod 841 is greater than the air pressure pushing force of the inner tube 846, thereby causing the main rod 841 to return to its original position. The limit pin 844 re-engages with the connecting sleeve 842, thereby causing the inner tube 846 and the vertical air chamber 91 to re-form a sealed cavity, and the gas is re-pressurized in the inner tube 846.

[0059] During the repeated pressure storage and release process of the main rod body 841, the material guide drive continues to work, and the main shaft 82 continuously drives the curtain rod 84 to rotate through the transmission gear set 83, and at this time, several curtain rods 84 rotate in the same direction.

[0060] During the rotation of several curtain rods 84, the inner piston 847 and the accumulator spring 848 work together to intermittently generate high-pressure airflow inside the inner tube 846. This intermittent high-pressure airflow causes the main rod 841 to vibrate intermittently, thus preventing the manure from getting stuck between the main rods 841 and ensuring that the manure can pass stably through the main rods 841. This also ensures the stability of the manure turning process. Furthermore, by controlling the vibration of the main rod 841 during rotation, the manure is prevented from sticking to the main rod 841, further ensuring the smoothness of the manure turning process. At the same time, by accumulating pressure on the pumped airflow, the impact of the ejected airflow is ensured, improving the dispersing effect of the airflow on the manure. The fluctuating ejected airflow allows the manure to flow with the fluctuating high-pressure airflow, further ensuring the dispersing effect of the airflow on the manure.

[0061] Furthermore, by using the accumulator spring 848 to store high-pressure airflow, compared with directly ejecting high-pressure airflow, the output power of the pump 7 can be effectively reduced, thus reducing energy waste.

[0062] Example 3, based on Example 2, is distinguished by the fact that the main shaft 82 is divided into two parts: a driving shaft and a driven shaft. Specifically, the main shaft 82 includes two shafts of the same length, and the joint ends of the two shafts are connected by a transmission gear set 83. The two shafts rotate in opposite directions through the transmission gear set 83.

[0063] The difference between Example 2 and Example 3 lies in the material guiding and driving process.

[0064] refer to Figure 5 During the material guiding drive operation, the material guiding motor drives the left main shaft 82 to rotate. The left main shaft 82 continuously drives the left curtain rod 84 to rotate through the transmission gear set 83. At the same time, the left main shaft 82 drives the right main shaft 82 to rotate in the opposite direction through the transmission gear set 83. The right main shaft 82 continuously drives the right curtain rod 84 to rotate in the opposite direction through the transmission gear set 83. At this time, the rotation directions of several curtain rods 84 on the left and right sides are opposite, and the rotation direction of the central curtain rod 84 is the same as the rotation direction of the left curtain rod 84.

[0065] It should be noted that both sides of the curtain rod 84 rotate towards the center, so that the manure pile can fall into the central area of ​​the turning conveyor belt 6, and avoid the manure pile falling into the gap between the turning conveyor belt 6 and the fermentation tank 1.

[0066] Example 4, Reference Figure 3 and Figure 4 Based on Embodiment 3, further, a plurality of curtain rods 84 are provided with shredders. In an optional embodiment, a plurality of shredders are provided on the outside of the main rod 841, and the shredders of adjacent main rods 841 are alternately distributed up and down. A spiral blade 85 is fixedly connected to the outside of the main rod 841 at the center position. A horizontal air outlet 911 is opened on the outside of the flat shovel head 9, and the horizontal air outlet 911 is connected to the vertical air chamber 91.

[0067] It should be noted that, in the initial state, the main rod 841 is inserted into the interior of the vertical air chamber 91, at which time the main rod 841 seals the interface between the vertical air chamber 91 and the horizontal air outlet 911.

[0068] By setting up several shredders, including several horizontally rotating shredders, the crushing and dispersing effect of the manure pile is further enhanced. Compared with the existing vertically rotating shredders, the horizontally rotating shredders can effectively reduce the splash height of the manure pile, preventing it from splashing to the outside during the turning process. The horizontally rotating shredders cause the manure pile to splash laterally, and since the manure pile is flanked by the walls of the fermentation tank 1, the splash range of the manure pile is effectively reduced, further ensuring the turning effect of the manure pile.

[0069] Meanwhile, the curtain rod 84 at the center is equipped with a spiral blade 85. The spiral blade 85 rotates upward, while the manure piles on both sides rotate towards the center, causing the manure to accumulate towards the center. The spiral blade 85 drives the manure pile in the center area to turn upward, thereby further achieving the effect of loosening the manure pile and making it easier for the manure pile to fall onto the top of the turning conveyor belt 6, ensuring the turning effect of the manure pile and thus ensuring the fermentation effect of the manure pile.

[0070] Furthermore, since the flat shovel head 9 is equipped with a forward-facing transverse air outlet 911, when the main rod body 841 moves upward, the transverse air outlet 911 connects to the vertical air chamber 91. Therefore, when releasing high-pressure gas, the high-pressure gas is ejected forward through the transverse air outlet 911, so that the high-pressure airflow acts on the manure pile from the bottom, thereby ensuring the effect of the airflow on the manure pile, preventing the manure pile from sticking together, allowing the manure pile to be loosely stacked, and ensuring the fermentation effect of the manure pile.

[0071] Example 5, Reference Figure 5 , Figure 6 , Figure 10 and Figure 11Based on Embodiment 4, the distinguishing feature is that the shredder and spiral blade 85 on the outside of the main rod 841 are replaced by a tilting plate 86, and it also includes a closed transverse air outlet 911. The air outlet is located outside the tilting plate 86. Specifically, several tilting plates 86 are rotatably connected to the outside of the main rod 841. The tilting plates 86 between adjacent main rods 841 are alternately distributed vertically, and the tilting plates 86 of adjacent main rods 841 are staggered by 90 degrees. The width of the tilting plate 86 is large. At the distance between adjacent main rods 841, the inside of the turning plate 86 is provided with an air outlet chamber 862. An inner connecting pipe 861 for connecting the inner tube 846 is provided outside the air outlet chamber 862. An air valve piston 863 is slidably connected inside the air outlet chamber 862. An air valve spring 864 is provided between the air valve piston 863 and the air outlet chamber 862. A pull rope 865 is provided between the air valve piston 863 and the main rod 841. An air outlet hole 866 is provided outside the air outlet chamber 862.

[0072] The difference from Embodiment 4 is that during the rotation of the main rod 841, it drives several turning plates 86 to rotate. Since the several turning plates 86 are arranged alternately, during the rotation of the turning plates 86, the turning plates 86 alternately push the piled manure into one side of the turning track 6, so that the piled manure entering the side of the turning track 6 is stacked alternately, thereby ensuring the uniformity of manure mixing during the turning process and ensuring the turning effect.

[0073] And when the flipping plate 86 contacts the adjacent main rod 841, refer to Figure 10 and Figure 11 The main rod 841 blocks the material, causing the tipping plate 86 to deflect and rotate smoothly to the other side of the main rod 841. The tipping plate 86 strikes the main rod 841 during rotation, further increasing the vibration effect of the main rod 841 and the tipping plate 86. This prevents the manure from accumulating and blocking in front of the main rod 841, and effectively avoids the manure from sticking to the tipping plate 86 and the main rod 841.

[0074] It should be noted that a stroke amplification mechanism is provided between the pull rope 865 and the air valve piston 863. The present invention uses two coaxially mounted reels (which is a conventional technical means and will not be described in detail in the present invention). When the pull rope 865 pulls the air valve piston 863, the pull rope 865 pulls the small diameter reel to rotate, the small diameter reel drives the large diameter reel to rotate, and the large diameter reel pulls the air valve piston 863 through the pull rope 865.

[0075] Meanwhile, during the deflection of the tipping plate 86, the air valve piston 863 inside the air outlet chamber 862 is pulled by the pull rope 865, causing the air valve piston 863 to disengage from the closed air outlet chamber 862, thereby connecting the air outlet chamber 862, the air outlet 866 and the inner tube 846, and the high-pressure airflow inside the inner tube 846 is discharged through several air outlets 866.

[0076] It should be noted that the time for the inner tube cavity 846 to accumulate pressure is less than the time for the tipping plate 86 to alternately contact the main rod body 841.

[0077] When the air pressure value of the inner tube 846 reaches the control point where the main rod 841 and the connecting sleeve 842 disengage, the main rod 841 is in an upward offset state. At this time, the tilting plate 86 deflects, and the high-pressure airflow inside the inner tube 846 is discharged through the air outlet 866. At this time, the air pressure inside the main rod 841 decreases, the main rod 841 resets, and the main rod 841 and the connecting sleeve 842 resume engagement.

[0078] Repeat the above process to complete the up-and-down vibration process of the main rod 841 and the alternating pushing of the material by the flipping plate 86, while the air outlet 866 of the flipping plate 86 intermittently sprays out high-pressure airflow.

[0079] The high-pressure airflow inside the inner tube 846 is ejected through several air outlets 866 at different positions, thereby effectively increasing the ejection position of the high-pressure airflow and thus increasing the effect of the ejected airflow on the manure pile. The high-pressure airflow ejected at different positions further increases the effect of the ejected airflow on the manure pile, which not only effectively avoids the manure pile from being blocked on the outside of the main rod 841, but also further increases the contact between the manure pile and oxygen, ensuring the subsequent fermentation effect of the manure pile.

[0080] Example 6: A method for efficient fermentation of chicken manure for livestock farms, comprising the following steps:

[0081] S1. Prepare the main ingredients, and pre-dry the chicken manure to control the moisture content of the chicken manure to be 50%-60%;

[0084] S4. Fermentation maintenance: When the temperature exceeds 65℃ or begins to drop, the material turning conveyor 6 and the material blocking rod 8 are used to turn the pile.

[0085] S5. Compost turning: The material blocking rod 8 controls the compost to be evenly spread to the turning conveyor 6, and the turning conveyor 6 drives the compost to gradually complete the turning process.

[0086] S6, the maturation stage, fermentation lasts for 20-30 days until the pile temperature drops below 40℃, and the material is grayish-brown, loose and odorless.
