Description

Technical Field

[0001] The present invention relates to the technical field of fermentation treatment of livestock and poultry manure, and in particular to a system and method for efficiently treating livestock and poultry manure by utilizing composite microorganisms. Background Art

[0002] At present, the treatment of livestock and poultry manure is a major problem in livestock and poultry farms. Livestock and poultry manure is accompanied by a lot of stench, and usually a composting design is used to pile up a large amount of it together, slowly rot, and use it as fertilizer, but this method is too time-consuming;

[0003] To solve this problem, in the prior art, aeration materials and aerobic biological agents are generally mixed into livestock and poultry manure to form compost raw materials. An aeration system is used to aerate the compost raw materials, thereby allowing the compost raw materials to ferment aerobically and achieve efficient treatment of livestock and poultry manure.

[0004] Although the existing technology improves the aerobic fermentation efficiency of livestock and poultry manure by turning and aerating the compost raw materials, it still has the following defects: the compost raw materials are prone to agglomeration during the fermentation process, especially at the bottom of the compost raw materials. It is not easy to break up the condensed raw material blocks during the turning process, and these condensed raw material blocks will affect the effect of aerobic fermentation. The aeration structure arranged in the compost raw materials will make the fermentation bed uneven, and the compost raw materials are not easy to transfer from the fermentation bed after fermentation is completed. Moreover, since the aeration holes of the aeration structure are always located inside the compost raw materials, the aeration holes are easily blocked when aeration is stopped. Summary of the Invention

The front ends of the stirring drum and the stirring rotating shaft are both connected to the reverse stirring power component.

[0018] A method for using a system for efficiently treating livestock and poultry manure by using composite microorganisms includes the following steps:

[0019] Step 1, collect livestock and poultry manure into the compost mixing box, add materials for adjusting the carbon-nitrogen ratio and air permeability into the compost mixing box, then add a composite microbial inoculant into the compost mixing box. The reverse stirring power component works to drive the stirring drum and the stirring rotating shaft to rotate reversely, thereby driving the drum turning longitudinal rod and the rotating shaft turning longitudinal rod to rotate reversely in the compost mixing box, and mixing the livestock and poultry manure, the materials for adjusting the carbon-nitrogen ratio and air permeability, and the composite microbial inoculant in the compost mixing box evenly to form compost raw materials;

[0020] Step 2, control the feeding hydraulic cylinder to extend to lift the right end of the compost mixing box, and the compost raw materials in the compost mixing box are poured onto the upper right side of the aerobic fermentation pallet through the guiding plate;

[0021] Step 3, switch the motor to drive the switching shaft and the switching flipping rod to rotate clockwise by 180 degrees to make the cutting edge of the shovel blade face downward. The height adjustment component drives the shovel plate in the compost transfer shoveling mechanism to descend, and then the transverse movement component drives the shovel plate in the compost transfer shoveling mechanism to move leftward to level the compost raw materials on the upper side of the aerobic fermentation pallet. The compost raw materials are spread flat near the upper side of the aeration mounting plate on the aerobic fermentation pallet;

[0022] Step 4: The switching motor drives the switching shaft and the switching turning rod to rotate counterclockwise by 180 degrees, so that the compost turning and dispersing mechanism is set downward. The turning motor works to drive the turning shaft to rotate. The turning shaft drives the turning bent rod and the dispersing bent rod to rotate through the fixed end sleeve and the movable end sleeve, and cooperates with the turning support rod and the dispersing support rod to regularly turn the compost raw materials spread near the upper side of the aeration installation plate. During the turning process, the reciprocating movement control component drives the movable end sleeve to move back and forth. The movable end sleeve drives the dispersing support rod to move back and forth through the dispersing bent rod. The dispersing support rod moves back and forth relative to the turning support rod, and the agglomerated raw material blocks in the compost raw materials are dispersed as the compost raw materials are turned.

[0023] Step 5: The aeration vertical cylinder extension control component drives the support ring and the aeration vertical cylinder to move upward relative to the aeration installation plate. The top of the aeration vertical cylinder extends into the spread compost raw materials. The blower blows air into the aeration vertical cylinder through the branch pipe, and the air in the aeration vertical cylinder is sent into the compost raw materials through the air holes, accelerating the aerobic fermentation process in the compost raw materials.

[0024] Compared with the prior art, the beneficial effects of the system and method for efficiently treating livestock and poultry manure by using composite microorganisms are as follows:

[0025] 1. The turning motor works to drive the turning shaft to rotate, thereby driving the turning bent rod and the dispersing bent rod to rotate, and cooperating with the turning support rod and the dispersing support rod to turn the compost raw materials, which is used to maintain the uniformity of the compost raw materials. During the turning process, the reciprocating movement control component drives the movable end sleeve to move back and forth, and drives the dispersing support rod to move back and forth relative to the turning support rod through the dispersing bent rod. The agglomerated raw material blocks in the compost raw materials are dispersed as the compost raw materials are turned.

[0026] 2. The aeration vertical cylinder extension control component can drive the aeration vertical cylinder to move up and down. When aeration is required, the top of the aeration vertical cylinder extends into the compost raw materials, and aerates the compost raw materials through the air holes, increasing the oxygen content in the compost raw materials, and can also be used for dissipating heat in the compost raw materials. When aeration is not required, the top surface of the aeration vertical cylinder is flush with the upper side of the aerobic fermentation support plate. The air holes at the top of the aeration vertical cylinder are hidden in the vertical sliding holes, avoiding being blocked after the aeration stops. At this time, the upper side of the aerobic fermentation support plate is flat, and it is convenient for the compost raw materials to be shoveled away from the aerobic fermentation support plate by the shovel plate after the compost raw materials are fermented, and it is convenient for the compost raw materials to be transferred after fermentation.

[0027] 3. When turning the compost raw materials, the agglomerated raw material blocks can also be dispersed, which is convenient for maintaining the uniformity of the compost raw materials, conducive to accelerating the aerobic fermentation efficiency of the compost raw materials and improving the effect of aerobic fermentation. The aeration vertical cylinder can be lifted and lowered, and the upper side of the aerobic fermentation support plate can be kept flat when transferring the compost, which is convenient for transferring the compost after aerobic fermentation. The air holes on the aeration vertical cylinder retract into the vertical sliding holes after the aeration stops and are not easily blocked.

[0028] 4. It can effectively decompose the organic matter in livestock and poultry manure, reduce environmental pollution, and convert livestock and poultry manure into valuable fertilizers. Description of the Drawings

DETAILED DESCRIPTION

[0041] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0042] For example 1, please refer to Figures 1 to 11, this embodiment provides a technical solution: a system for efficiently treating livestock and poultry manure by using composite microorganisms, including an aerobic fermentation pallet 1. A plurality of round troughs are horizontally and equidistantly arranged on the aerobic fermentation pallet 1. Support frames 12 are respectively arranged on the front and rear sides of the bottom of the aerobic fermentation pallet 1. Side baffles 11 are respectively fixedly connected to the front and rear sides of the top of the aerobic fermentation pallet 1 to prevent the compost raw materials on the aerobic fermentation pallet 1 from falling from the front and rear sides of the aerobic fermentation pallet 1. It also includes a compost treatment equipment displacement mechanism 2, a compost treatment switching mechanism 3, and an anti-interference aeration mechanism 7;

[0043] The compost treatment equipment displacement mechanism 2 includes a transverse movement component, an arched frame 23, and a height adjustment component. Two transverse movement components are respectively installed on the two support frames 12. The two ends of the arched frame 23 are respectively connected to the two transverse movement components. Two height adjustment components are respectively installed on the front and rear sides of the arched frame 23;

[0044] Specifically, the transverse movement component includes a linear guide rail 21 and a linear motor 22. Two horizontal linear guide rails 21 are respectively fixedly connected to the two support frames 12. Two linear motors 22 are respectively installed in cooperation with the two linear guide rails 21. The two linear motors 22 are respectively connected to the two ends of the arched frame 23. The two linear motors 22 move synchronously along the respective linear guide rails 21 installed in cooperation, so as to drive the arched frame 23 to move horizontally left and right;

[0045] The height adjustment component includes a vertical chute 24, a lifting hydraulic cylinder 25, and a vertical sliding seat 26. Vertical chutes 24 are respectively opened on the front and rear sides of the arched frame 23. Two vertical sliding seats 26 are respectively vertically slidably connected in the two vertical chutes 24. The bottom ends of two lifting hydraulic cylinders 25 are respectively fixedly connected to the inner bottoms of the two vertical chutes 24. The top ends of the two lifting hydraulic cylinders 25 are respectively connected to the bottoms of the corresponding vertical sliding seats 26. The two lifting hydraulic cylinders 25 can drive the two vertical sliding seats 26 to move up and down synchronously by synchronously telescoping, so as to adjust the height of the compost treatment switching mechanism 3.

[0046] The compost treatment switching mechanism 3 is installed between the two vertical sliding seats 26 in the two height adjustment components. A compost transfer and shoveling mechanism 4 is installed on the top of the compost treatment switching mechanism 3, and a compost turning and dispersing mechanism 5 is installed on the bottom of the compost treatment switching mechanism 3;

[0047] The compost treatment switching mechanism 3 includes a switching shaft 31, a switching motor 32, a switching flipping rod 33, and a connecting frame 34. The two vertical sliding seats 26 in the two height adjustment components are respectively rotatably connected to the front and rear ends of the switching shaft 31. One end of the switching shaft 31 is fixedly connected to the output shaft of the switching motor 32. The switching motor 32 is installed on the vertical sliding seat 26 in the height adjustment component. The two ends of the switching shaft 31 are respectively fixedly connected to the middle parts of the two switching flipping rods 33. A connecting frame 34 is fixedly connected between the left sides of the tops of the two switching flipping rods 33. The switching motor 32 is used to drive the switching shaft 31 to rotate. The switching shaft 31 drives the compost transfer and shoveling mechanism 4 and the compost turning and dispersing mechanism 5 to move through the switching flipping rod 33, so that the compost transfer and shoveling mechanism 4 or the compost turning and dispersing mechanism 5 is arranged downward, and the compost transfer and shoveling mechanism 4 or the compost turning and dispersing mechanism 5 shovels or turns and disperses the compost raw materials. The switching motor 32 drives the switching shaft 31 to rotate 180 degrees each time. The switching motor 32 needs to drive the switching shaft 31 to rotate 180 degrees in the reverse direction during the next operation to avoid the cable winding and damage of the compost transfer and shoveling mechanism 4 or the compost turning and dispersing mechanism 5.

[0048] The compost transfer and shoveling mechanism 4 includes a shovel plate 43, an angle adjustment electric telescopic rod 46, and a shovel edge 47.

[0050] The switching motor 32 operates to drive the switching shaft 31 to rotate clockwise by 180 degrees. The switching shaft 31 drives the cutting edge 47 of the shovel plate 43 to face downward through the switching flipping rod 33. The height adjustment assembly drives the shovel plate 43 to descend, and then the transverse movement assembly drives the shovel plate 43 to move leftward, so as to level the compost raw materials on the upper side of the aerobic fermentation pallet 1. At the same time, the compost that has completed fermentation on the aerobic fermentation pallet 1 can also be scraped and transferred leftward, transferred from the left end of the aerobic fermentation pallet 1 to the transport vehicle. The telescopic movement of the angle adjustment electric telescopic rod 46 can adjust the angle of the shovel plate 43 relative to the upper side of the aerobic fermentation pallet 1, which is beneficial for the cutting edge 47 on the shovel plate 43 to scrape off the compost attached to the bottom of the aerobic fermentation pallet 1.

[0052] Specifically, the number of the turning bent rods 54 is three, and one end of the turning bent rod 54 close to the fixed end sleeve 53 is distributed along the radial direction of the fixed end sleeve 53, and the end of the turning bent rod 54 far from the fixed end sleeve 53 is parallel to the turning shaft 51;

[0053] The number of the dispersing bent rods 57 is also three, and one end of the dispersing bent rod 57 close to the movable end sleeve 56 is distributed along the radial direction of the movable end sleeve 56, and the end of the dispersing bent rod 57 far from the movable end sleeve 56 is parallel to the turning shaft 51, and each dispersing bent rod 57 is respectively close to a corresponding turning bent rod 54, so that the dispersing support rods 58 on the dispersing bent rod 57 are close to the turning support rods 55 on the turning bent rod 54. The number of the turning support rods 55 and the dispersing support rods 58 is selected according to specific situations;

The longitudinal limit groove 59 and the longitudinal limit bar 510 slide together to allow the movable end sleeve 56 to move only forward and backward relative to the turning shaft 51.

[0055] The turning motor 52 drives the turning shaft 51 to rotate, and the turning shaft 51 drives the turning bent rod 54 and the breaking bent rod 57 to rotate through the fixed end sleeve 53 and the movable end sleeve 56, and cooperates with the turning support rod 55 and the breaking support rod 58 to regularly turn the compost raw materials spread near the upper side of the aeration mounting plate 71, which can improve the uniformity of the compost raw materials and increase the oxygen content in the compost raw materials. During the turning process, the reciprocating control component drives the movable end sleeve 56 to reciprocate back and forth, and the movable end sleeve 56 drives the breaking support rod 58 to reciprocate back and forth through the breaking bent rod 57. The breaking support rod 58 reciprocates back and forth relative to the turning support rod 55. As the compost raw materials are turned, the condensed raw material blocks in the compost raw materials are broken up, which is beneficial to improving the efficiency of aerobic fermentation.

[0056] The reciprocating control assembly includes a toggle ring 511, a toggle rod 512, a limiting guide rod 513, a motor base plate 514, a scattering motor 515, a turntable 516 and a connecting rod 517.

The top of the toggle rod 512 is fixedly connected to the front end of the limiting guide rod 513. The middle part of the limiting guide rod 513 is longitudinally slidably connected to the limiting hole on the corresponding switching flip rod 33. The rear end of the limiting guide rod 513 is movably connected to one end of the connecting rod 517 through the movable shaft one, and the other end of the connecting rod 517 is movably connected to the eccentric position on the upper side of the turntable 516 through the movable shaft two. The middle part of the turntable 516 is fixedly connected to the output shaft at the top of the scattering motor 515. The scattering motor 515 is installed on the corresponding switching flip rod 33 through the motor base plate 514.

[0057] The motor base plate 514 is used to install the scattering motor 515 to drive the turntable 516 to rotate. The turntable 516 and the connecting rod 517 form a similar mechanism to a crank-connecting rod. The turntable 516 drives the limiting guide rod 513 to move back and forth through the connecting rod 517, thereby driving the movable end sleeve 56 to move back and forth relative to the flip shaft 51 through the toggle ring 511 and the toggle rod 512. Since the toggle ring 511 is rotatably connected to the movable end sleeve 56, the movable end sleeve 56, the scattering bent rod 57, and the scattering support rod 58 can also move back and forth as the flip shaft 51 rotates. The frequency of the reciprocating movement of the movable end sleeve 56, the scattering bent rod 57, and the scattering support rod 58 can be adjusted according to the rotation speed of the scattering motor 515.

[0058] The anti-interference aeration mechanism 7 is installed in each round trough, and a compost anti-interference detection mechanism 10 is installed in the middle of the anti-interference aeration mechanism 7.

[0059] The anti-interference aeration mechanism 7 includes an aeration mounting plate 71, an aeration vertical cylinder 72, aeration holes 73, a support ring 74, a branch pipe 75, a blower 76, a blower bracket 77, and an aeration vertical cylinder extension control component. An aeration mounting plate 71 is installed in each round trough. The upper surface of the aeration mounting plate 71 is flush with the upper surface of the aerobic fermentation support plate 1. A plurality of vertical sliding holes are arranged in a circular array on the aeration mounting plate 71. The number of vertical sliding holes on the aeration mounting plate 71 can be selected according to needs. Each aeration mounting plate 71 can be provided with eight vertical sliding holes. A blower bracket 77 is arranged below the aeration mounting plate 71. The top of the blower bracket 77 is fixedly connected with a support ring 74. The support ring 74 is concentric with the aeration mounting plate 71. The side of the support ring 74 is connected to the aeration mounting plate 71 through the aeration vertical cylinder extension control component. And the top of the support ring 74 is fixedly connected to the bottom end of the aeration vertical cylinder 72 corresponding to the position of the vertical sliding hole. The aeration vertical cylinder 72 is vertically slidably connected with the vertical sliding hole. Aeration holes 73 are evenly arranged on the outer peripheral side of the top of the aeration vertical cylinder 72. A blower 76 is installed on the blower bracket 77. The air outlet of the blower 76 is connected to the bottom end of each aeration vertical cylinder 72 through a branch pipe 75.

[0060] The anti-interference aeration mechanism 7 further includes a sealing rubber ring 712. An annular groove is respectively arranged at the top of each vertical sliding hole. The sealing rubber ring 712 is arranged in the annular groove. The sealing rubber ring 712 is slidably sleeved on the outer side of the top of the aeration vertical cylinder 72. The gap between the top of the aeration vertical cylinder 72 and the inner wall of the top of the vertical sliding hole is sealed by the sealing rubber ring 712 to prevent the moisture of the compost raw materials from entering the vertical sliding hole.

[0061] The aeration vertical cylinder extension control component includes side ear plates 78, vertical guide posts 79, a control motor 710, and a lead screw 711. Two side ear plates 78 are respectively arranged on the left and right sides of the support ring 74. A vertical guide post 79 is vertically slidably connected in the sliding hole of one of the side ear plates 78. The top end of the vertical guide post 79 is fixedly connected to the bottom of the aeration mounting plate 71. A vertical lead screw 711 is threadedly connected in the threaded hole of the other side ear plate 78. The top of the lead screw 711 is fixedly connected to the output shaft of the control motor 710. The control motor 710 is installed at the bottom of the aeration mounting plate 71. When the control motor 710 works to drive the lead screw 711 to rotate clockwise, the lead screw 711 drives the support ring 74 to move downward along the vertical guide post 79 through the threaded action with the side ear plate 78. When the control motor 710 works to drive the lead screw 711 to rotate counterclockwise, the support ring 74 moves upward along the vertical guide post 79. Thus, the aeration vertical cylinder 72 can be driven by the support ring 74 to move up and down.

[0062] When it is necessary to aerate the compost raw materials regularly, the aeration vertical cylinder extends out of the control assembly to drive the support ring 74 and the blower bracket 77 to move upward relative to the aeration mounting plate 71. The top of the aeration vertical cylinder 72 extends out of the top of the vertical sliding hole, and the air holes 73 at the top of the aeration vertical cylinder 72 enter the compost raw materials on the aerobic fermentation pallet 1. The blower 76 blows air into the aeration vertical cylinder 72 through the branch pipe 75, and the aeration vertical cylinder 72 aerates the compost raw materials through the air holes 73, increasing the oxygen content in the compost raw materials and promoting the fermentation process of aerobic bacteria in the compost raw materials. When aeration is not required, the aeration vertical cylinder extending control assembly drives the support ring 74 and the blower bracket 77 to move downward relative to the aeration mounting plate 71, so that the top surface of the aeration vertical cylinder 72 is flush with the upper side of the aerobic fermentation pallet 1. At this time, the upper side of the aerobic fermentation pallet 1 is flat, which is convenient for the shoveling and transfer of the compost fermented on the aerobic fermentation pallet 1. Moreover, the air holes 73 on the outer peripheral side of the top of the aeration vertical cylinder 72 are hidden in the vertical sliding hole and are not easily blocked.

[0063] The compost anti-interference detection mechanism 10 includes a detection lifting electric telescopic rod 101, a lifting seat plate 102, a detection lifting column 103, a pH sensor 104, and a temperature and humidity sensor 105. Detection through holes are respectively opened in the middle of each aeration mounting plate 71. A detection lifting column 103 is vertically slidably connected in the detection through hole. Grooves are respectively opened on both sides of the top of the detection lifting column 103. A pH sensor 104 is installed in one of the grooves, and a temperature and humidity sensor 105 is installed in the other groove. The bottom of the detection lifting column 103 is fixedly connected to a horizontal lifting seat plate 102. The top of the lifting seat plate 102 is fixedly connected to the bottom end of the detection lifting electric telescopic rod 101. The top end of the detection lifting electric telescopic rod 101 is fixedly connected to the bottom of the aeration mounting plate 71. When it is necessary to detect the condition of the compost raw materials, the detection lifting electric telescopic rod 101 shortens, so as to drive the detection lifting column 103 to move upward relative to the aeration mounting plate 71 in the detection through hole through the lifting seat plate 102, so that the pH sensor 104 and the temperature and humidity sensor 105 extend into the interior of the compost raw materials. The pH sensor 104 is used to detect the pH value of the compost raw materials, and the temperature and humidity sensor 105 is used to detect the temperature and humidity of the compost raw materials. Corresponding countermeasures can be taken according to the detection results.

[0064] When it is necessary to shovel and transfer the compost raw materials, the detection lifting electric telescopic rod 101 extends, driving the detection lifting column 103 to move downward relative to the aeration mounting plate 71 in the detection through hole, so that the top surface of the detection lifting column 103 is flush with the upper side of the aerobic fermentation pallet (1), and it will not interfere with the shoveling of the compost raw materials by the compost transfer and shoveling mechanism (4).

[0065] During use, the transverse movement component is used to drive the arched frame 23 to move left and right along the aerobic fermentation pallet 1 and the support frame 12, and the height adjustment component is used to drive the compost treatment switching mechanism 3 to move up and down relative to the arched frame 23, so as to change the heights of the compost transfer and lifting mechanism 4 and the compost turning and dispersing mechanism 5. When the compost treatment switching mechanism 3 rotates, the compost transfer and lifting mechanism 4 or the compost turning and dispersing mechanism 5 can be set downward. When the compost transfer and lifting mechanism 4 is set downward, cooperating with the transverse movement component and the height adjustment component can shovel and transfer the compost raw materials on the aerobic fermentation pallet 1. When the compost turning and dispersing mechanism 5 is set downward, cooperating with the transverse movement component and the height adjustment component can turn the compost raw materials on the aerobic fermentation pallet 1, and can also disperse the raw material blocks condensed in the compost raw materials, making the compost raw materials more uniform, and can also increase the oxygen content in the compost raw materials, thereby improving the aerobic fermentation efficiency of the compost raw materials. The compost treatment switching mechanism 3 needs to rotate 180 degrees in the reverse direction after each 180-degree rotation to avoid damage to the cables connecting the compost transfer and lifting mechanism 4 or the compost turning and dispersing mechanism 5. The anti-interference aeration mechanism 7 can aerate the compost raw materials on the aerobic fermentation pallet 1, increase the oxygen content in the compost raw materials, and can also reduce the temperature in the compost raw materials to avoid the influence of high temperature in the compost raw materials on the growth and reproduction of aerobic bacteria. The compost anti-interference detection mechanism 10 is used to detect indexes such as the temperature, humidity and pH value of the compost raw materials, and corresponding measures can be taken according to the detection results to keep the indexes of the compost raw materials within a suitable range.

[0066] Embodiment 2. Please refer to Figures 1 to 11 , this embodiment provides a technical solution: a system for efficiently treating livestock and poultry manure by using composite microorganisms. This embodiment is substantially the same in structure as Embodiment 1, and the difference lies in:

[0067] It further includes a liquid agent follow-up addition mechanism 6. The liquid agent follow-up addition mechanism 6 includes a liquid agent outlet 61, a rotary joint 62, a pipeline assembly, a liquid pump 67 and a liquid agent supply assembly. The inside of the turning shaft 51 is a hollow structure. A plurality of liquid agent outlets 61 are longitudinally and equidistantly inserted on the side surface of the turning shaft 51. The front end of the turning shaft 51 passes through the corresponding switching and turning rod 33 and is connected to one end of the pipeline assembly through the rotary joint 62. The other end of the pipeline assembly is connected to the outlet of the liquid pump 67. The liquid pump 67 is installed on the top of the arched frame 23, and the inlet of the liquid pump 67 is connected to a liquid agent supply assembly.

[0068] The pipeline assembly includes a pipe support 63, an elbow pipe 64, an elbow pipe and hose joint 65, and a hose 66. The front end of the turning shaft 51 is connected to the bottom end of the elbow pipe 64 through a rotary joint 62. The elbow pipe 64 is fixed to the corresponding switching and turning lever 33 through the pipe support 63. The top end of the elbow pipe 64 is connected to one end of the hose 66 through the elbow pipe and hose joint 65. The other end of the hose 66 is connected to the outlet of the liquid pump 67. By connecting the elbow pipe 64 and the turning shaft 51 through the rotary joint 62, when the turning shaft 51 rotates, the elbow pipe 64 can still feed the liquid agent into the turning shaft 51. The setting of the hose 66 can maintain the effective connection between the liquid pump 67 and the elbow pipe 64 when the compost treatment switching mechanism 3 works.

[0069] The liquid agent supply assembly includes a liquid filling hard pipe 68, an alkali liquid tank 69, an acid liquid tank 610, a suction pipe 611, a suction pipe solenoid valve 612, a water pipe solenoid valve 613, and a water pipe and hose joint 614. The alkali liquid tank 69 and the acid liquid tank 610 are respectively arranged at the top of the arched frame 23. The inlet of the liquid pump 67 is connected to one end of the liquid filling hard pipe 68. The other end of the liquid filling hard pipe 68 is provided with a water pipe and hose joint 614, and the water pipe and hose joint 614 is connected to an external soft water pipe. A water pipe solenoid valve 613 is installed at one end of the liquid filling hard pipe 68 close to the water pipe and hose joint 614. The middle part of the liquid filling hard pipe 68 is respectively connected to the top ends of two suction pipes 611. The bottom ends of the two suction pipes 611 are respectively inserted into the inner bottoms of the alkali liquid tank 69 and the acid liquid tank 610. Two suction pipe solenoid valves 612 are respectively installed on the two suction pipes 611. Alkali liquid is contained in the alkali liquid tank 69, and acid liquid is contained in the acid liquid tank 610.

[0070] The liquid agent supply assembly supplies the liquid agent into the liquid pump 67. The liquid pump 67 sends the liquid agent into the inside of the turning shaft 51 through the pipeline assembly and the rotary joint 62, and then adds it into the compost raw materials through the liquid agent outlet 61. When the compost turning and dispersing mechanism 5 turns the compost raw materials, it can be evenly mixed with the compost raw materials. Different liquid agents can be selected to be added into the compost raw materials according to the detection results of the compost anti-interference detection mechanism 10. pH sensor 104, temperature and humidity sensor 105

[0071] During specific operation, when the pH sensor 104 in the compost anti-interference detection mechanism 10 detects that the pH value in the compost raw materials is too low and is not conducive to the aerobic fermentation of the compound microbial agent, the water pipe solenoid valve 613 and the suction pipe solenoid valve 612 above the acid liquid tank 610 are closed, and the suction pipe solenoid valve 612 above the alkali liquid tank 69 is opened. The liquid pump 67 works, extracts the alkali liquid in the alkali liquid tank 69 through the suction pipe 611, then sends it into the turning shaft 51 through the pipeline assembly, and then adds it into the compost raw materials through the liquid agent outlet 61 to increase the pH value of the compost raw materials;

[0072] When the pH sensor 104 in the compost anti-interference detection mechanism 10 detects that the pH value in the compost raw material is too high and is not conducive to the aerobic fermentation of the compound microbial inoculant, the water pipe solenoid valve 613 and the suction pipe solenoid valve 612 above the lye tank 69 are closed, the suction pipe solenoid valve 612 above the acid tank 610 is opened, the liquid pump 67 operates, and the acid liquid in the acid tank 610 is extracted through the suction pipe 611, and then sent into the turning shaft 51 through the pipeline assembly, and then added into the compost raw material through the liquid agent outlet 61 to lower the pH value of the compost raw material;

[0073] When the temperature and humidity sensor 105 in the compost anti-interference detection mechanism 10 detects that the humidity of the compost raw material is too low, the two suction pipe solenoid valves 612 are closed, the water pipe solenoid valve 613 is opened, the liquid pump 67 operates, and the external purified water is sent into the turning shaft 51 through the liquid addition rigid pipe 68 and the external flexible water pipe, and added into the compost raw material through the liquid agent outlet 61 to increase the humidity of the compost raw material;

[0074] When adding the liquid agent into the compost raw material through the liquid agent follow-up addition mechanism 6, it is necessary for the compost turning and dispersing mechanism 5 to turn the compost raw material so that the added liquid agent can be quickly and fully mixed with the compost raw material.

[0075] When the temperature and humidity sensor 105 in the compost anti-interference detection mechanism 10 detects that the temperature or humidity in the compost raw material is too high, the anti-interference aeration mechanism 7 is controlled to continuously aerate to reduce the temperature or humidity in the compost raw material.

[0076] Example three, please refer to Figures 1 to 11 , this embodiment provides a technical solution: a system for efficiently treating livestock and poultry manure with compound microorganisms. This embodiment is roughly the same as that of Example two, and the difference lies in:

[0077] It further includes a compost feeding mechanism 8, which comprises an end seat 81, a feeding shaft 82, a mounting bracket 83, a guiding plate 84, a compost mixing box 85, a first movable seat 86, a feeding hydraulic cylinder 87, a second movable seat 88, and a baffle plate 89. At the front and rear ends of the right side of the aerobic fermentation pallet 1, two end seats 81 are respectively fixedly connected. The two end seats 81 are movably connected to the left end of the guiding plate 84 through the feeding shaft 82. The right end of the guiding plate 84 is fixedly connected to the left side of the top of the compost mixing box 85. The bottom of the compost mixing box 85 is of an arc-shaped structure. The bottom of the compost mixing box 85 is fixedly connected to the second movable seat 88. The second movable seat 88 is movably connected to one end of the feeding hydraulic cylinder 87 through a second hinge shaft. At the right ends of the two support frames 12, a mounting bracket 83 is fixedly connected. In the middle of the mounting bracket 83, a first movable seat 86 is fixedly connected. The first movable seat 86 is movably connected to the other end of the feeding hydraulic cylinder 87 through a first hinge shaft. At the front and rear sides of the top of the guiding plate 84, baffle plates 89 are respectively arranged. The baffle plates 89 cover the front and rear sides of the guiding plate 84 to prevent the compost raw materials passing through the upper side of the guiding plate 84 from falling from the front and rear sides of the guiding plate 84.

[0078] The compost mixing box 85 is used for holding livestock and poultry manure. After the amount of livestock and poultry manure in the compost mixing box 85 is appropriate, materials for adjusting the carbon-nitrogen ratio and air permeability and compound microbial inoculants in appropriate amounts are added. After being mixed evenly, compost raw materials are formed. The feeding hydraulic cylinder 87 extends, and the compost raw materials in the compost mixing box 85 can be poured onto the upper right side of the aerobic fermentation pallet 1 through the guiding plate 84, thus completing the feeding work of the compost raw materials.

[0079] Example 4, please refer to Figures 1 to 11 , this example provides a technical solution: a system for efficiently treating livestock and poultry manure by using compound microorganisms. This example is roughly the same as that of Example 3, and the difference lies in:

[0080] It further includes a compost raw material full stirring mechanism 9, which comprises a reverse stirring power component, a stirring drum 91, a stirring shaft 92, a drum spoke 99, a drum turning longitudinal rod 910, a shaft spoke 911, and a shaft turning longitudinal rod 912. At the front end of the compost mixing box 85, a longitudinal stirring drum 91 is rotatably connected. At the outer peripheral side of one end of the stirring drum 91 located inside the compost mixing box 85, a plurality of drum spokes 99 are arranged in an annular array. At the rear side of the end of the drum spoke 99 away from the stirring drum 91, a drum turning longitudinal rod 910 is fixedly connected. Inside the stirring drum 91, a stirring shaft 92 is rotatably connected. The rear end of the stirring shaft 92 extends to the outside of the rear end of the stirring drum 91, and at the outer peripheral side of the rear end of the stirring shaft 92, a plurality of shaft spokes 911 are arranged in an annular array. The length of the shaft spoke 911 is less than that of the drum spoke 99. At the rear side of the end of the shaft spoke 911 away from the stirring shaft 92, a shaft turning longitudinal rod 912 is fixedly connected. The front ends of the stirring drum 91 and the stirring shaft 92 are both connected to the reverse stirring power component.

[0081] The reverse stirring power assembly includes a rotary drum bevel gear 93, a rotating shaft bevel gear 94, a power support 95, a transmission shaft 96, a transmission bevel gear 97, and a stirring motor 98. A rotary drum bevel gear 93 is fixedly sleeved on the outer side of the front end of the stirring rotary drum 91, and a rotating shaft bevel gear 94 is fixedly sleeved on the outer side of the front end of the stirring rotating shaft 92. The rotating shaft bevel gear 94 is located on the front side of the rotary drum bevel gear 93, and the front end of the stirring rotating shaft 92 is fixedly connected to the output shaft of the stirring motor 98. The stirring motor 98 is installed on the front side of the compost mixing box 85 through the power support 95. A horizontal transmission shaft 96 is rotatably connected to the power support 95. A transmission bevel gear 97 is fixedly connected to the left end of the transmission shaft 96. The transmission bevel gear 97 is located between the right sides of the rotary drum bevel gear 93 and the rotating shaft bevel gear 94, and the front side of the transmission bevel gear 97 is meshed with the rotating shaft bevel gear 94, and the rear side of the transmission bevel gear 97 is meshed with the rotary drum bevel gear 93. When the stirring motor 98 works, it drives the stirring rotating shaft 92 and the rotating shaft bevel gear 94 to rotate clockwise. The rotating shaft bevel gear 94 drives the stirring rotary drum 91 to rotate counterclockwise through the transmission of the transmission bevel gear 97 and the rotary drum bevel gear 93, so as to drive the stirring rotary drum 91 and the stirring rotating shaft 92 to rotate in the reverse direction;

[0082] The reverse stirring power assembly can drive the stirring rotary drum 91 and the stirring rotating shaft 92 to rotate in the reverse direction. For example, it can drive the stirring rotating shaft 92 to rotate clockwise while driving the stirring rotary drum 91 to rotate counterclockwise. Since the rotating shaft spoke 911 is shorter than the rotary drum spoke 99, the rotary drum turning vertical rod 910 and the rotating shaft turning vertical rod 912 will not interfere with each other when rotating in the reverse direction. The rotary drum turning vertical rod 910 and the rotating shaft turning vertical rod 912 stir the compost raw materials in the compost mixing box 85 in the reverse direction to make the compost raw materials evenly mixed. The rotary drum turning vertical rod 910 and the rotating shaft turning vertical rod 912 can turn up the raw materials at the bottom of the compost mixing box 85 to make the uniformity of the upper and lower layers of compost raw materials in the compost mixing box 85 better. The axis of the stirring rotating shaft 92 coincides with the center of the circle where the arc-shaped structure at the bottom of the compost mixing box 85 is located. When the rotary drum turning vertical rod 910 rotates to the bottom inside the compost mixing box 85, it can better adhere to the bottom inside the compost mixing box 85, so as to better turn up the compost raw materials at the bottom of the fertilizer mixing box 85.

[0083] Please refer to Figures 1 to 11 , a method for using a system for efficiently treating livestock and poultry manure by using composite microorganisms, including the following steps:

[0084] Collect livestock and poultry manure into the compost mixing box 85, add materials for adjusting the carbon-nitrogen ratio and aeration into the compost mixing box 85, then add a compound microbial inoculant into the compost mixing box 85. The reverse stirring power assembly operates to drive the stirring drum 91 and the stirring shaft 92 to rotate in the reverse direction, thereby driving the rotating drum turning lever 910 and the rotating shaft turning lever 912 to rotate in the reverse direction in the compost mixing box 85, and mixing the livestock and poultry manure, the materials for adjusting the carbon-nitrogen ratio and aeration, and the compound microbial inoculant in the compost mixing box 85 evenly to form compost raw materials;

[0085] Control the feeding hydraulic cylinder 87 to extend, lift the right end of the compost mixing box 85, and the compost raw materials in the compost mixing box 85 are poured onto the upper right side of the aerobic fermentation support plate 1 through the guiding plate 84;

[0086] Switch the motor 32 to drive the switching shaft 31 and the switching flipping rod 33 to rotate clockwise by 180 degrees, so that the cutting edge 47 of the shovel plate 43 is arranged downward. The height adjustment assembly drives the shovel plate 43 in the compost transfer shoveling mechanism 4 to descend, and then the transverse movement assembly drives the shovel plate 43 in the compost transfer shoveling mechanism 4 to move leftward, leveling the compost raw materials on the upper side of the aerobic fermentation support plate 1, and the compost raw materials are spread flat near the upper side of the aeration installation plate 71 on the aerobic fermentation support plate 1;

[0087] Switch the motor 32 to drive the switching shaft 31 and the switching flipping rod 33 to rotate counterclockwise by 1,800 degrees, so that the compost turning and dispersing mechanism 5 is arranged downward. The turning motor 52 operates to drive the turning shaft 51 to rotate. The turning shaft 51 drives the turning bent rod 54 and the dispersing bent rod 57 to rotate through the fixed end sleeve 53 and the movable end sleeve 56, and cooperates with the turning support rod 55 and the dispersing support rod 58 to turn the compost raw materials spread flat near the upper side of the aeration installation plate 71 regularly. During the turning process, the reciprocating movement control component drives the movable end sleeve 56 to reciprocate back and forth. The movable end sleeve 56 drives the dispersing support rod 58 to reciprocate back and forth through the dispersing bent rod 57, and the dispersing support rod 58 reciprocates back and forth relative to the turning support rod 55, and breaks up the agglomerated raw material blocks in the compost raw materials as the compost raw materials are turned;

[0088] The aeration vertical cylinder extension control component drives the support ring 74 and the aeration vertical cylinder 72 to move upward relative to the aeration installation plate 71. The top of the aeration vertical cylinder 72 extends into the flat compost raw materials. The blower 76 blows air into the aeration vertical cylinder 72 through the branch pipe 75, and the air in the aeration vertical cylinder 72 is sent into the compost raw materials through the air holes 73, accelerating the aerobic fermentation process in the compost raw materials.

[0089] Among them, the water content in the compost raw materials usually remains at 45%-65%, and the initial pH value of the compost raw materials usually remains neutral or slightly alkaline.

[0090] It should be noted that the linear motor 22, lifting hydraulic cylinder 25, switching motor 32, angle-adjusting electric telescopic rod 46, flipping motor 52, dispersing motor 515, blower 76, control motor 710, detection lifting electric telescopic rod 101, liquid pump 67, suction pipe solenoid valve 612, water pipe solenoid valve 613, feeding hydraulic cylinder 87, and stirring motor 98 disclosed in the above embodiments are all controlled by an external PLC controller to work. The control method uses existing technologies, and both the pH sensor 104 and the temperature and humidity sensor 105 transmit the detected situations to the external PLC controller through electrical signals. Specifically, the switching motor 32 uses a servo motor with a self-locking function, and the control motor 710 uses a servo motor.

[0091] Specifically, the proportions of livestock and poultry manure, materials for adjusting the carbon-nitrogen ratio and aeration, and the composite microbial inoculant are selected according to needs.

[0092] The materials for adjusting the carbon-nitrogen ratio and aeration are straw and wood chips.

[0093] The composite microbial inoculant is composed of a mixture of Bacillus subtilis, Bacillus licheniformis, and Bacillus megaterium, and the proportions of the three can be adjusted according to needs.

[0094] The composite microbial inoculant is prepared through screening, mutagenesis, and amplification culture.

[0095] 1. Screening of aerobic composting bacteria;

[0096] To solve the problem of fewer available microbial inoculants during the high-temperature aerobic composting process, strains that can efficiently degrade organic matter are screened from fully decomposed livestock and poultry manure organic fertilizers, and qualitative screening is carried out through selective media such as high salt, heavy metals, ammonia, and hydrogen sulfide.

[0097] Sample collection: Samples are collected from fully decomposed livestock and poultry manure organic fertilizers, and these samples will be used for the isolation and screening of beneficial microbial strains.

[0098] Pretreatment: The collected samples are pretreated to facilitate the isolation and cultivation of microorganisms. This may include adjusting the pH value, adding nutrients, etc.

[0099] Dilution and inoculation: The pretreated samples are appropriately diluted and then inoculated into the screening medium. The screening medium usually contains specific components that can promote the growth of target microorganisms while inhibiting other non-target microorganisms.

[0100] Cultivation: The inoculated medium is cultivated under suitable conditions, and qualitative screening is carried out through selective media such as high salt, heavy metals, ammonia, and hydrogen sulfide, enabling the target microorganisms to grow and reproduce.

[0101] Colony screening: By observing the morphological characteristics of colonies, select microbial colonies that may be beneficial to the composting process.

[0102] Purification culture: Purify and culture the selected colonies to obtain a single microbial strain.

[0103] Physiological and biochemical identification: Conduct physiological and biochemical tests on the purified strains to determine their characteristics and functions.

[0104] Molecular biology identification: Use molecular biology methods, such as 16S rRNA gene sequencing, to conduct more precise identification of the strains.

[0105] Functional testing: Conduct functional tests on the selected strains to evaluate their degradation ability, high salt tolerance, heavy metal tolerance, deodorization effect, etc. during the composting process.

[0106] Strain optimization: According to the results of functional testing, select strains with the least production of high salt tolerance, heavy metal tolerance, ammonia, and hydrogen sulfide for subsequent nuclear radiation mutagenesis breeding.

[0107] 2. Strain nuclear radiation mutagenesis;

[0108] Adopt nuclear radiation mutagenesis breeding to generate new genetic variations, which helps to improve specific traits of the strains, such as increasing the yield of metabolites or enhancing stress resistance, etc. Nuclear radiation mutagenesis breeding is a method that uses γ-rays as a physical mutagen to treat microbial strains to increase the gene mutation frequency.

[0109] Selection of starting strains: Select the strains with good performance screened out for nuclear radiation mutagenesis.

[0110] Preparation of bacterial suspension: Culture the starting strains to the logarithmic growth phase, then collect the bacterial cells and prepare them into a cell suspension. The cells in the cell suspension should be evenly dispersed and in an active growth state.

[0111] Determine the nuclear radiation dose: According to the radiation sensitivity of the strains and the mutagenesis purpose, determine the appropriate radiation dose. Too high a dose may cause cell death, while too low a dose may not have an obvious mutagenesis effect.

[0112] Nuclear radiation treatment: Expose the bacterial suspension to γ-rays for radiation treatment. During the treatment process, the radiation dose should be well controlled. The mutagenesis dose of the γ-rays in the present invention is 20 - 200 Gy.

[0113] Intermediate culture: After radiation treatment, inoculate the bacterial solution into an appropriate medium for intermediate culture to allow the mutant genes to express the mutant phenotypes.

[0114] Isolation of mutant strains: Mutant strains are isolated from the mutagenized population through different screening methods, such as resistance screening, auxotrophic screening, etc.

[0115] Screening and identification of mutant strains: The isolated mutant strains are further screened and identified to select mutant strains with necessary traits.

[0116] Genetic stability test: The screened mutant strains are subjected to genetic stability tests to ensure the stable transmission of their genetic characteristics.

[0117] Performance evaluation: The production performance, growth characteristics, etc. of the mutant strains are evaluated to obtain three strains of Bacillus subtilis, Bacillus licheniformis, and Bacillus megaterium with strong ability to decompose organic matter, high salt tolerance, heavy metal tolerance, and high temperature tolerance.

[0118] 3. Expansion culture of microbial inoculants;

[0119] The selected strains of Bacillus subtilis, Bacillus licheniformis, and Bacillus megaterium are expanded and cultured to prepare a compound microbial inoculant.

[0120] After the compost raw materials are fermented, they need to be screened to remove large pieces of undecomposed materials and need to be dried.

[0121] This invention significantly improves the treatment efficiency of livestock and poultry manure, shortens the treatment cycle, reduces the environmental pollution caused by livestock and poultry manure, converts livestock and poultry manure into fertilizer, and realizes the recycling of resources.

[0122] In other embodiments, the number of round troughs is three, so three aeration installation plates 71 are provided. The three aeration installation plates 71 are respectively located at the upper right end, upper middle part, and upper left end of the aerobic fermentation pallet 1. The livestock and poultry manure collected each time in livestock and poultry breeding is just enough to form a sufficient amount of compost raw materials in the compost mixing box 85. The compost raw materials formed in the compost mixing box 85 are spread flat on the upper right end of the aerobic fermentation pallet 1. At this time, the anti-interference aeration mechanism 7 at the right end aerates the compost raw materials at the upper right end of the aerobic fermentation pallet 1. When the livestock and poultry manure collected next time is enough to form a sufficient amount of compost raw materials in the compost mixing box 85, the compost treatment equipment displacement mechanism 2 and the compost transfer and shoveling mechanism 4 are used to transfer the compost raw materials that have been aerobically fermented for a period of time at the upper right end of the aerobic fermentation pallet 1 to the upper middle part of the aerobic fermentation pallet 1, realizing one-time turning and displacement of the compost raw materials. The newly mixed compost raw materials are poured and spread flat on the upper right end of the aerobic fermentation pallet 1. By analogy, the compost raw materials located in the upper middle part of the aerobic fermentation pallet 1 next time are turned and transferred to the upper left end of the aerobic fermentation pallet 1. After the compost raw materials are turned and displaced twice, the aerobic fermentation treatment is just completed. Since the compost raw materials are displaced during the turning process, the turning effect is good. With the help of the compost transfer and shoveling mechanism 4, the compost raw materials attached to the aerobic fermentation pallet 1 can be shoveled up and the turning is thorough.
