Description

Technical Field

[0001] The present invention relates to the technical field of chicken manure fermentation, and specifically provides a high-efficiency chicken manure fermentation device and method for a farm. Background Art

[0002] In order to ensure the recyclability of resources, during livestock breeding, it is necessary to centrally collect and ferment the manure of the bred livestock. Fermentation is a process in which microorganisms rapidly develop under certain temperature, humidity, and sufficient oxygen environment, utilizing the organic matter and residual protein in the manure. In the aerobic fermentation process, in order to ensure oxygen supply and improve the oxygen supply conditions, it is also necessary to turn over the manure pile in a timely manner.

[0003] In a Chinese patent with the patent publication number CN215209169U, there is disclosed a quick-maturing fermentation device for poultry manure organic fertilizer, including a frame body. A driving motor and a driving wheel are connected to each other on the frame body. The driving wheels are located at the left and right ends of the lower side of the frame body, and the driving motor is located on the upper side of the frame body. A support platform is also provided on the upper side of the frame body. A slide rail is provided on the lower side of the frame body, and a U-shaped plate is slidably connected to the slide rail. A slideway is provided on the support platform, and a moving rod is provided in the slideway. The upper end of the moving rod is located above the support platform, and the lower end of the moving rod is connected to a seat body located above the U-shaped plate. The lower side of the U-shaped plate is hinged to the middle of a first telescopic rod, and the first telescopic rod is hinged to the lower end of the first telescopic rod. The second telescopic rod is hinged to the right side of the connecting plate. Track support plates are provided on the front and rear sides of the connecting plate. A driving wheel and a driven wheel are provided on the track support plates, and a track is provided on the driving wheel and the driven wheel. By means of the driving wheels, movement can be carried out on the fermentation tank. The driving wheel drives the nail plate to rotate, and the nails turn over the materials piled up in the fermentation tank. Through rapid rotation, the materials at the bottom of the fermentation tank are turned and scraped onto the track support plate, and the materials are continuously conveyed to the highest point of the turning track through the rapidly rotating track support plate and then fall into the tank on the rear side of the moving direction to be neatly piled up again. The materials are in full contact with the air during the fermentation and turning process, thereby improving the oxygen supply in the re-piled manure pile.

[0004] However, during the movement of the turning track, the contact between the turning track and the manure pile is not restricted. As a result, when the turning track contacts the manure pile, the thickness of the manure pile driven by the turning track is uneven, leading to an incomplete turning effect of the manure pile during the turning process and affecting the final turning effect.

Prepare the main material, preliminarily dry the chicken manure, and control the water content of the chicken manure to be 50%-60%; S2. Prepare the auxiliary materials, crush one or several mixtures of straw, rice husk, wood chips, mushroom residue and hay, with a total weight of 20%-30% of the chicken manure, and prepare one or several mixtures of brown sugar, wheat bran and humic acid, with a total weight of 1%-5% of the chicken manure; S3.

Ripe stage, the fermentation lasts for 20-30 days until the pile temperature drops below 40°C, and the material is grayish-brown, loose and odorless.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. The chicken manure high-efficiency fermentation equipment and method for the farm avoid the turning track directly contacting the manure pile during the turning process by using the material blocking rod in cooperation with the turning track. The material blocking rod controls the turning track to gradually contact and convey the manure pile, thereby ensuring the uniformity of conveying the manure pile during the manure turning process. And through the regulation of the material blocking rod to pass the material, the uniformity of turning the manure pile is ensured, and further the turning effect of the manure pile is effectively ensured.

[0017] 2. The chicken manure high-efficiency fermentation equipment and method for the farm avoid the manure pile sticking to the bottom of the fermentation tank by making the flat shovel head fit the bottom of the fermentation tank, further improving the turning effect on the bottom of the manure pile. At the same time, during the turning process, the air pump pumps gas into the shunt chamber, and the gas enters the interior of the vertical air chamber through the shunt chamber and the air guide pipe, and then is discharged through the air chamber. Through the continuously discharged air flow, the gas fluidity inside the manure pile is increased. The air flow inside the manure pile increases the looseness of the manure pile on the top of the flat shovel head, and further increases the contact effect between the top manure pile and oxygen, thereby avoiding the phenomenon of manure pile agglomeration. At the same time, after turning the manure, the looseness of the stacked manure is ensured, and the compost fermentation effect is ensured.

[0018] 3. The chicken manure high-efficiency fermentation equipment and method for the farm, through the combined action of the inner piston and the pressure accumulator spring, intermittently form high-pressure air flow inside the inner pipe cavity. The intermittently formed high-pressure air flow causes the main rod body to generate intermittent vibration, so that the main rod body can continuously generate vibration during the rotation process, thereby avoiding the phenomenon of manure getting stuck between the main rod bodies, ensuring that the manure pile can stably pass through a number of main rod bodies, and further ensuring the stable progress during the manure turning process. And by controlling the main rod body to generate vibration during the rotation process, it further avoids the adhesion between the manure pile and the main rod body, thereby further ensuring the smoothness of the manure turning process. At the same time, through the pressure accumulation treatment of the pumped air flow, the impact of the ejected air flow is ensured, and the dispersing effect of the air flow on the manure pile is improved. Through the fluctuating ejected air flow, the manure pile can generate fluidity following the fluctuating high-pressure air flow, and further ensure the dispersing effect of the air flow on the manure pile.

[0019] 4. The chicken manure high-efficiency fermentation equipment and method for the farm, through the high-pressure air flow inside the inner pipe cavity spraying out through a number of air holes at different positions, effectively increases the spraying positions of the high-pressure air flow, and further increases the effect of the ejected air flow on the manure pile. The high-pressure air flow ejected from different positions further increases the action of the ejected air flow on the manure pile, not only effectively avoiding the phenomenon of manure pile blocking outside the main rod body, but also the air flow ejected from different positions further increases the contact effect between the manure pile and oxygen, ensuring the fermentation effect of the subsequent manure pile.

Detailed implementation mode

[0022] 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 a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0023] Example 1, please refer to Figures 1 - 2 、 Figures 5 - 8 A highly efficient chicken manure fermentation device for a farm, including a mobile base 3. A control base 4 and a cantilever platform 5 are arranged on the top of the mobile base 3. A turning belt 6 is arranged at the bottom of the cantilever platform 5. A flat shovel head 9 is arranged at the front end of the bottom of the turning belt 6. A plurality of material blocking rods 8 are arranged at the front bottom of the cantilever platform 5. A vertical air cavity 91 is opened at the top of the flat shovel head 9. The end of the material blocking rod 8 extends downward and is embedded in the vertical air cavity 91. The material blocking rod 8 includes a material guiding drive arranged at the top. The material blocking rod 8 is arranged in front of the turning belt 6.

[0024] It also includes a fermentation tank 1. Guide rails 2 are installed on both sides of the top of the fermentation tank 1. The mobile base 3 travels on the top of the guide rails 2. The width of the turning belt 6 is adapted to the width of the fermentation tank 1. The width of the fermentation tank 1 is 1.5 m to 2 m, and the height is 1 m to 1.5 m. A plurality of material blocking rods 8 are evenly distributed on the top of the turning belt 6.

[0025] The fermentation tank 1 is built in a chicken manure fermentation treatment greenhouse, and the length of the fermentation tank 1 is determined by the occupied length of the greenhouse.

[0026] During the fermentation process, mixed carbon-nitrogen auxiliary substances are added to the chicken manure to adjust the carbon-nitrogen ratio to 25 - 30:1. The mixed materials are stacked inside the fermentation tank 1, with a stack height of 1 - 1.5 meters, a width of 1.5 - 2 meters, and the length is determined by the length of the fermentation tank 1. Each layer of chicken manure is 20 - 30 cm thick. A mixture of bacterial agents is sprinkled. In the initial stage, a plastic film is covered to keep warm at 55 - 65 °C for 3 - 5 days for sterilization. When the temperature drops to 40 °C, the first turning of the pile is carried out, and then the pile is turned every 2 - 3 days. The humidity is kept at 50 - 60% throughout the process, and bamboo poles can be inserted to detect the internal humidity.

[0027] When turning the material, control the mobile base 3 to travel on the top of the guide rail 2, so that the material blocking rod 8 and the turning belt 6 gradually contact the manure pile. When contacting the manure pile, the material blocking rod 8 is in front of the turning belt 6 and first contacts the manure pile. The material guiding drive drives the material blocking rod 8 to rotate. During the rotation of the material blocking rod 8, it drives the manure pile to evenly fall behind the material blocking rod 8, and then gradually contacts the turning belt 6. The turning belt 6 drives the manure pile to be evenly conveyed backward to the rear of the turning belt 6, and finally is stacked behind the turning belt 6 to complete the turning operation of the manure pile fermentation.

[0028] By using the material blocking rod 8 in cooperation with the material turning track 6, it is avoided that the material turning track 6 directly contacts the manure pile during the material turning process. The material blocking rod 8 controls the material turning track 6 to gradually contact and convey the manure pile, thereby ensuring the uniformity of conveying the manure pile during the manure turning process by the material turning track 6. And by adjusting the material passing through the material blocking rod 8, the uniformity of manure turning is ensured, and further the manure turning effect is effectively guaranteed.

[0029] Reference Figure 8 , in an alternative embodiment, the material turning track 6 includes an adjusting bracket 61. The adjusting bracket 61 is adjustably installed at the bottom of the cantilever platform 5. A guiding material track 62 is movably connected to the outside of the adjusting bracket 61. A driving system 63 for driving the guiding material track 62 to rotate is arranged inside the adjusting bracket 61. An air conveying shaft tube 64 is also arranged inside the adjusting bracket 61. A connecting air pipe 65 is movably connected to the outside of the air conveying shaft tube 64. The connecting air pipe 65 extends to the outside end of the adjusting bracket 61 and is provided with an air inlet 66. A pump air machine 7 is arranged outside the air inlet 66. The pump air machine 7 is installed on the top of the cantilever platform 5.

[0030] Reference Figure 7 , a shunt chamber 93 is fixedly installed at the bottom of the flat shovel head 9. The shunt chamber 93 is communicated with the air conveying shaft tube 64. A plurality of air guide pipes 92 are arranged outside the shunt chamber 93. The air guide pipes 92 are communicated with a plurality of vertical air cavities 91.

[0031] During the material turning process, the flat shovel head 9 fits the bottom of the fermentation tank 1, thereby avoiding the adhesion of the manure pile to the bottom of the tank and further improving the material turning effect on the bottom of the manure pile. At the same time, during the material turning process, the pump air machine 7 pumps gas into the shunt chamber 93. The gas enters the inside of the vertical air cavity 91 through the shunt chamber 93 and the air guide pipes 92, and then is discharged through the vertical air cavity 91. Through the continuously discharged air flow, the gas fluidity inside the manure pile is increased. The looseness of the manure pile on the top of the flat shovel head 9 is increased by the flowing air inside the manure pile, and the contact effect between the top manure pile and oxygen is further increased, thereby avoiding the phenomenon of manure pile-up, and at the same time ensuring the looseness of the manure pile after manure turning and the effect of compost fermentation.

[0032] Reference Figure 3 , in an alternative embodiment, the material guiding drive includes a drive box 81 fixedly connected to the bottom of the cantilever platform 5. A main shaft 82 is rotatably connected inside the drive box 81. The material blocking rod 8 further includes a curtain rod 84. The curtain rod 84 is rotatably connected to the bottom of the drive box 81. A transmission gear set 83 is arranged between the curtain rod 84 and the main shaft 82. A material guiding motor is arranged outside the main shaft 82.

[0033] When the material blocking rod 8 is working, the material guiding motor drives the main shaft 82 to rotate. The main shaft 82 drives a plurality of curtain rods 84 to rotate through a transmission gear set 83. The rotating curtain rods 84 drive the manure stack in contact with the curtain rods 84 to pass through the material, so that the manure stack can pass through the curtain rods 84 evenly and stably, thereby achieving the effect of adjusting and controlling the amount of manure stack contacted by the turning belt 6 and ensuring the stability of the turning belt 6 in contacting and conveying the manure stack.

[0034] Example 2, refer to Figure 7 and Figure 9 , on the basis of Example 1, further, the curtain rod 84 includes a main rod body 841 and a connecting sleeve rod 842. The connecting sleeve rod 842 extends into the inside of the driving box 81 and is in transmission connection with the transmission gear set 83. A return spring 843 is arranged between the connecting sleeve rod 842 and the main rod body 841. A limiting pin 844 that is clamped with the connecting sleeve rod 842 is arranged inside the main rod body 841. A limiting spring 845 is arranged between the limiting pin 844 and the main rod body 841. An inner tube cavity 846 is opened inside the main rod body 841. An inner piston 847 is slidably connected inside the inner tube cavity 846. A pressure accumulating spring 848 is arranged between the inner piston 847 and the inner tube cavity 846. The main rod body 841 is inserted into the inside of the vertical air cavity 91. The inner tube cavity 846 extends to the bottom end inside the vertical air cavity 91 and is provided with an air inlet hole.

[0035] When gas is pumped into the vertical air cavity 91, the gas enters the inside of the inner tube cavity 846 through the air inlet hole. The gas squeezes the inner piston 847 inside the inner tube cavity 846. The inner piston 847 squeezes the pressure accumulating spring 848. And when the air pressure value inside the inner tube cavity 846 is greater than the restricting force of the return spring 843 and the limiting pin 844 on the main rod body 841, so that the limiting pin 844 disengages from restricting the main rod body 841 and the connecting sleeve rod 842. Then at this time, the air pressure value inside the inner tube cavity 846 is greater than the squeezing force of the return spring 843. Thus, under the action of the air pressure, the main rod body 841 is driven to move upward. At the same time, the gas inside the inner tube cavity 846 is discharged, and the air pressure inside the inner tube cavity 846 decreases. Then the pushing force of the return spring 843 on the main rod body 841 is greater than the air pressure pushing force inside the inner tube cavity 846. Thus, the main rod body 841 is reset, and the limiting pin 844 is re-clamped with the connecting sleeve rod 842. Thus, the inner tube cavity 846 and the vertical air cavity 91 re-form a sealed cavity, and the gas accumulates pressure again inside the inner tube cavity 846.

[0036] During the repeated pressure accumulation and release process of the main rod body 841, the material guiding drive continues to work, the main shaft 82 continuously drives the curtain rod 84 to rotate through the transmission gear set 83, and at this time, the rotating directions of a plurality of curtain rods 84 are the same.

[0037] During the rotation of the plurality of curtain rods 84, a high-pressure airflow is intermittently formed inside the inner tube cavity 846 through the cooperation of the inner piston 847 and the pressure storage spring 848. The intermittently formed high-pressure airflow causes the main rod body 841 to vibrate intermittently, so that the main rod body 841 can continuously vibrate during the rotation process, thereby avoiding the pile of manure from getting stuck between the main rod bodies 841, thereby ensuring that the pile of manure can stably pass through the plurality of main rod bodies 841, thereby ensuring the stability of the manure turning process, and by controlling the vibration of the main rod body 841 during the rotation process, further avoiding the pile of manure and the main rod body 841 from sticking, thereby further ensuring the smoothness of the pile of manure turning process, and at the same time, by accumulating pressure on the pumped airflow, thereby ensuring the impact of the ejected airflow, improving the dispersing effect of the airflow on the pile of manure, and by fluctuating the ejected airflow, the pile of manure can follow the fluctuating high-pressure airflow to generate fluidity, thereby further ensuring the evacuation effect of the airflow on the pile of manure.

[0038] Moreover, by accumulating the high-pressure airflow by the pressure accumulator spring 848, compared with directly ejecting the high-pressure airflow, the output power of the air pump 7 can be effectively reduced, thereby reducing energy waste.

[0039] Embodiment 3 is based on Embodiment 2, and its distinguishing feature is that the main shaft 82 is divided into two parts, namely, a driving shaft and a driven shaft. Specifically, the main shaft 82 includes two shafts of the same length, and the connecting ends of the two shafts are connected by a transmission gear set 83, and the two shafts can realize reverse rotation through the transmission gear set 83.

[0040] On the basis of the second embodiment, the difference lies in the working process of the material guide drive.

[0041] refer to Figure 5 During the material guide driving process, the material guide motor drives the left main shaft 82 to rotate, and 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 in the opposite direction through the transmission gear set 83, and the right main shaft 82 continuously drives the right curtain rod 84 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 center curtain rod 84 is the same as that of the left curtain rod 84.

[0042] It should be noted that the curtain rods 84 on both sides rotate toward the center, so that the manure pile can easily fall into the central area of ​​the material turning track 6, and prevent the manure pile from falling into the gap between the material turning track 6 and the fermentation tank 1 on both sides.

[0043] Example 4, reference Figure 3 and Figure 4, on the basis of Embodiment 3, further, a plurality of curtain rods 84 are provided with shredding knives. In an optional embodiment, a plurality of shredding knives are provided on the outer part of the main rod body 841. The shredding knives on adjacent main rod bodies 841 are distributed alternately up and down. A spiral blade 85 is fixedly connected to the outer part of the main rod body 841 at the central position. A transverse air outlet 911 is formed in the outer part of the flat shovel head 9, and the transverse air outlet 911 communicates with the vertical air cavity 91.

[0044] It should be noted that in the initial state, the main rod body 841 is inserted into the interior of the vertical air cavity 91. At this time, the main rod body 841 seals the interface between the vertical air cavity 91 and the transverse air outlet 911.

[0045] By providing a plurality of shredding knives, by providing a plurality of horizontally rotating shredding knives, the crushing and dispersing effect on the manure heap is further increased. Moreover, compared with the existing vertically rotating shredding knives, the horizontally rotating shredding knives can effectively reduce the splashing height of the manure heap, avoid the manure heap splashing to the outside during the material turning process. The horizontally rotating shredding knives cause the manure heap to splash horizontally, and the two sides of the manure heap are the walls of the fermentation tank 1, so as to effectively reduce the splashing range of the manure heap and further ensure the material turning effect of the manure heap.

[0046] At the same time, a spiral blade 85 is provided on the curtain rod 84 at the central position. The spiral blade 85 rotates upward, while the manure heaps on both sides rotate towards the central direction, causing the manure heap to accumulate towards the central position. The spiral blade 85 drives the manure heap in the central area to turn upward, further achieving the effect of loosening the manure heap, and facilitating the manure heap to fall on the top of the material turning track 6, ensuring the manure turning effect of the manure heap, and further ensuring the fermentation effect of the manure heap.

[0047] And because the flat shovel head 9 is provided with a forward transverse air outlet 911, when the main rod body 841 moves upward, the transverse air outlet 911 communicates with the vertical air cavity 91. Therefore, when high-pressure gas is released, the high-pressure gas is ejected forward through the transverse air outlet 911, enabling the high-pressure air flow to act on the manure heap from the bottom of the manure heap, thereby ensuring the effect of the air flow on the manure heap, avoiding the manure heap from sticking, enabling the manure heap to be loosely stacked, and ensuring the fermentation effect of the manure heap.

[0048] Embodiment 5, refer to Figure 5 、 Figure 6 、 Figure 10 and Figure 11, on the basis of Embodiment 4, the difference lies in that the chopping knives and spiral blades 85 outside the main rod body 841 are replaced by turning plates 86, and a closed lateral air outlet 911 is further included, and the air outlet position is arranged outside the turning plate 86. Specifically, a plurality of turning plates 86 are rotatably connected to the outside of the main rod body 841, and the turning plates 86 between adjacent main rod bodies 841 are alternately distributed up and down, and the turning plates 86 of adjacent main rod bodies 841 are misaligned by 90 degrees. The width of the turning plate 86 is greater than the distance between adjacent main rod bodies 841. An air outlet cavity 862 is formed inside the turning plate 86. An inner connecting pipe 861 for communicating with the inner pipe cavity 846 is arranged outside the air outlet cavity 862. A valve piston 863 is slidably connected inside the air outlet cavity 862. An air valve spring 864 is arranged between the valve piston 863 and the air outlet cavity 862. A pull rope 865 is arranged between the valve piston 863 and the main rod body 841. An air outlet hole 866 is formed outside the air outlet cavity 862.

[0049] The difference from Embodiment 4 is that the main rod body 841 drives a plurality of turning plates 86 to rotate during the rotation process. Since a plurality of turning plates 86 are alternately arranged, during the rotation process 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 one side of the turning track 6 is alternately stacked, thereby ensuring the uniformity of the mixing of the piled manure during the manure turning process and ensuring the manure turning effect.

[0050] And when the turning plate 86 contacts the adjacent main rod body 841, refer to Figure 10 and Figure 11 , blocked by the main rod body 841, so that the turning plate 86 deflects, enabling the turning plate 86 to smoothly rotate to the other side of the main rod body 841. By knocking the main rod body 841 during the rotation process of the turning plate 86, the vibration effect of the main rod body 841 and the turning plate 86 is further increased, thereby achieving the effect of preventing the piled manure from accumulating and blocking in front of the main rod body 841, and effectively avoiding the problem of the piled manure sticking to the turning plate 86 and the main rod body 841.

[0051] It should be noted that a stroke amplification mechanism is arranged between the pull rope 865 and the valve piston 863. The present invention uses two wire wheels coaxially installed (which are conventional technical means and are not described in detail in the present invention). When the pull rope 865 pulls the valve piston 863, the pull rope 865 drives the small-diameter wire wheel to rotate, the small-diameter wire wheel drives the large-diameter wire wheel to rotate, and the large-diameter wire wheel pulls the valve piston 863 through the pull rope 865.

[0052] At the same time, during the deflection process of the turning plate 86, the valve piston 863 inside the air outlet cavity 862 is pulled by the pull rope 865, so that the valve piston 863 disengages from closing the air outlet cavity 862, thereby enabling the air outlet cavity 862, the air outlet hole 866 and the inner pipe cavity 846 to communicate, and the high-pressure air flow inside the inner pipe cavity 846 is discharged through a plurality of air outlet holes 866.

[0053] It should be noted that the time for the inner lumen 846 to store pressure is less than the time for the turning plate 86 to alternately contact the main rod body 841.

[0054] When the air pressure value in the inner lumen 846 reaches the value for controlling the disengagement of the main rod body 841 from the connecting sleeve rod 842, the main rod body 841 is in a state of being deflected upward. At this time, the turning plate 86 deflects, and the high-pressure air flow inside the inner lumen 846 is discharged through the air outlet holes 866. At this time, the air pressure inside the main rod body 841 decreases, the main rod body 841 resets, and the main rod body 841 and the connecting sleeve rod 842 resume clamping.

[0055] In the process of repeating the above, the up-and-down vibration process of the main rod body 841 and the alternate material pushing of the turning plate 86 are completed. At the same time, the high-pressure air flow intermittently jets out from the air outlet holes 866 of the turning plate 86.

[0056] The high-pressure air flow inside the inner lumen 846 jets out through a number of air outlet holes 866 at different positions, thereby effectively increasing the jetting positions of the high-pressure air flow, and further increasing the effect of the jetting air flow on the piled manure. Through the high-pressure air flow jetted out from different positions, the effect of the jetting air flow acting on the piled manure is further increased. This not only effectively avoids the phenomenon of material blocking on the outside of the main rod body 841, but also further increases the effect of the piled manure contacting with oxygen by the air flow jetted out from different positions, ensuring the subsequent fermentation effect of the piled manure.
