Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of chicken manure fermentation, in particular to a chicken manure fermentation device and method for preparing organic fertilizer based on chicken manure. BACKGROUND

[0002] Chicken manure is a high-performance organic fertilizer, which contains rich organic matter, nitrogen, phosphorus, potassium and various trace elements. It is not only low in cost, but also has remarkable effects. It can effectively activate soil vitality, enhance soil permeability, and effectively alleviate the problem of soil hardening. Therefore, it is favored in the field of agricultural production and is more convenient to obtain. However, it is worth noting that before applying chicken manure, it is necessary to ensure that it has been fully fermented. Fermentation decomposes organic matter into humus through the metabolic action of microorganisms, and kills pathogens and insect eggs, so that the fertilizer reaches a safe and easily absorbed state. Making biological manure fertilizer is an important part of biological agriculture and related industries.

[0003] For example, the publication number "CN115196996A" is "a microbial fermentation treatment device for chicken manure". The microbial fermentation treatment device can realize the automatic stirring, addition of microbial inoculum, dryness and humidity adjustment, and distribution of chicken manure, thereby greatly improving the efficiency of microbial fermentation treatment of chicken manure.

[0004] In order to improve the efficiency of chicken manure fermentation, it is necessary to add microbial inoculum to the chicken manure during fermentation. Usually, each gram of microbial inoculum contains hundreds of millions of live bacteria. In each fermentation of chicken manure, the amount of microbial inoculum added is small. In order to ensure the addition of microbial inoculum, it is a challenge to uniformly distribute the small amount of microbial inoculum into tens of tons of materials in the entire tank. Although the rotation or stirring function of the fermentation tank can mix the materials, it is very difficult to mix a small amount of microbial inoculum into a large amount of chicken manure. If the mixture is not uniform, different fermentation areas will be formed in the tank, resulting in uneven fermentation and affecting the quality of chicken manure fermentation. SUMMARY

[0005] The purpose of the present application is to provide a chicken manure fermentation device for preparing organic fertilizer based on chicken manure, which can spray microbial inoculum in the form of spray to the newly added chicken manure, and stir the chicken manure in the scraping part to realize the pre-mixing of a small amount of chicken manure before fermentation, improve the uniformity of fermentation, and improve the quality of subsequent chicken manure fermentation, so as to solve the problems raised in the background art.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. 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.

[0021] Example 1: Please refer to Figures 1 to 13 This invention provides a technical solution: a chicken manure fermentation device for preparing organic fertilizer based on chicken manure, including a tank 1, an inlet 2 at the rear of the tank 1, and a feeding component 3 at the rear end of the tank 1. The feeding component 3 adopts a single bucket elevator, which can automatically flip and enter the interior of the inlet 2 when it is lifted to the top. This is a mature existing technology and will not be described in detail. The chicken manure fermentation device also includes a premixing component 4 disposed at the top of the tank 1. The premixing component 4 includes a partition 41 fixedly connected to the interior of the tank 1. A motor 42 is fixedly connected to the top of the tank 1. The output shaft of the motor 42 passes through the tank 1 and is fixedly connected to a rotating shaft 43. A scraping part 44 is disposed on the outer wall of the rotating shaft 43. The scraping part 44 is used to scrape the added chicken manure.

[0022] The chicken manure fermentation device also includes a spray assembly 5 disposed on the top of the tank 1. The spray assembly 5 is used to dilute the fermentation-promoting agent with water and spray it onto the added chicken manure in the form of a spray. The spray assembly 5 includes a liquid tank 51 fixedly connected to the top of the tank 1. The spray assembly 5 also includes a ring frame 52 fixedly connected to the outside of the tank 1. An inlet pipe 53 is inserted between the ring frame 52 and the liquid tank 51. A liquid pump is installed inside the inlet pipe 53. An air inlet ring 54 is disposed on the ring side of the tank 1. A spray pipe 55 is inserted into the inner side of the air inlet ring 54. The end of the spray pipe 55 extends into the inside of the tank 1. A suction pipe 56 is inserted into the bottom of the spray pipe 55. The bottom of the suction pipe 56 extends into the inside of the ring frame 52. An air inlet pipe is inserted into the top of the air inlet ring 54.

[0023] A drop trough 10 is provided on the left side of the partition 41. A sealing plate 11 is provided inside the tank 1 near the drop trough 10. A hydraulic rod 12 is provided at the bottom of the sealing plate 11. The bottom of the hydraulic rod 12 is fixed to the tank 1.

[0024] By adopting the above technical solution, the microbial agent to be used is diluted with water before fermentation, and then the diluted microbial agent is placed into the liquid tank 51. The method of placement includes, but is not limited to, transportation through pipelines.

[0025] Subsequently, the chicken manure to be fermented is added into the tank 1 through the feeding component 3 from the inlet 2. During this process, the output shaft of the hydraulic rod 12 extends, causing the sealing plate 11 to seal the drop trough 10. The newly added chicken manure is located above the partition 41. Then, the output shaft of the motor 42 drives the rotating shaft 43 to rotate, which causes the scraper 44 to rotate and stir the newly added chicken manure.

[0026] Subsequently, the liquid pump inside the inlet pipe 53 is activated, and the diluted microbial agent inside the liquid tank 51 enters the ring frame 52 through the inlet pipe 53. Then, high-speed, high-pressure air is added from the air inlet pipe through an external air source. The air enters the air inlet ring 54 and then into the spray pipe 55. At this time, the air in the spray pipe 55 flows at high speed. According to Bernoulli's principle, the faster the flow rate, the lower the static pressure of the fluid. The diluted microbial agent inside the ring frame 52 rises through the suction pipe and enters the nozzle to mix with the high-speed airflow, so that the microbial agent is sprayed out in a liquid mist state towards the chicken manure. In this way, because the diluted microbial agent has a large volume and is sprayed onto the newly added chicken manure in the form of a spray, and is combined with the stirring of the chicken manure by the scraper part 44, a small amount of chicken manure is pre-mixed before fermentation, which improves the uniformity of fermentation and is beneficial to improving the quality of subsequent chicken manure fermentation.

[0027] After the chicken manure and diluted bacterial agent are premixed, the output shaft of the hydraulic rod 12 retracts, so that the sealing plate 11 does not block the trough 10. As the scraper 442 scrapes the chicken manure, the chicken manure falls from the trough 10 into the tank 1 below the partition 41 for fermentation.

[0028] The scraping part 44 includes a fixed ring 441 fixedly connected to the outer wall of the rotating shaft 43. A scraper 442 is fixedly connected to one side of the fixed ring 441, and a rotating shaft 443 is rotatably connected to the other side of the fixed ring 441. A stirring plate 444 is fixedly connected to the outer side of the rotating shaft 443. A lifting plate 45 is slidably connected inside the rotating shaft 43. An inclined groove 46 is provided inside the lifting plate 45. An inclined block 47 is movable inside the inclined groove 46. A small rod 48 is fixedly connected to the outer side of the inclined block 47. The end of the small rod 48 extends out of the rotating shaft 443 and a first spiral groove 49 is provided inside the rotating shaft 443. A first guide slider 410 is fixed inside the rotating shaft 443 and moves inside the first spiral groove 49. The outer side of the inclined block 47 and the inside of the inclined groove 46 are both inclined.

[0029] It should be noted that the bottom of scraper 442 is attached to the top of partition 41.

[0030] By adopting the above technical solution, as the fixed ring 441 rotates, the scraper 442 can rotate accordingly, which is beneficial for stirring the chicken manure on the top of the partition 41. The rotating shaft 443 and the stirring plate 444 also rotate accordingly. Since the lifting plate 45 can move up and down continuously, when the lifting plate 45 moves downward with the inclined groove 46, under the action of the inclined setting, the inclined block 47 can move with the small rod 48 towards the direction close to the rotating shaft 443. At this time, the small rod 48 and the rotating shaft 443 generate relative motion, so that the first guide slider 410 moves inside the first spiral groove 49, which is beneficial for the rotating shaft 443 to rotate with the stirring plate 444 around the axis of the rotating shaft 443.

[0031] It should be noted that the end of the rod 48 and the rotating shaft 443 are both fixedly connected with magnetic blocks, and the magnetic poles of the two magnetic blocks are the same on the side that are close to each other. According to the principle of like poles repulsion, when the lifting plate 45 moves upward with the inclined groove 46, the rod 48 and the inclined block 47 are reset under the action of magnetic repulsion. During this process, the rotating shaft 443 will also rotate with the stirring plate 444.

[0032] In this way, the mixing plate 444 can rotate while stirring the chicken manure. At this time, multiple mixing plates 444 turn the chicken manure over, which helps to turn the chicken manure at the bottom to the top position, thereby further facilitating the uniform mixing between the inoculant and the chicken manure and further improving the quality of fermentation.

[0033] The bottom of the partition 41 is equipped with a lifting assembly 6 for controlling the lifting plate 45 to rise and fall. The lifting assembly 6 includes a lifting frame 61 slidably connected to the outside of the rotating shaft 43. The top of the lifting frame 61 is provided with multiple toothed grooves 62, one side of which is inclined. The bottom of the partition 41 is fixedly connected to a fixing rod 63. The bottom of the fixing rod 63 is rotatably connected to a rotating component 64. The end of the rotating component 64 is located near the toothed groove 62. The outer wall of the rotating shaft 43 is fixedly connected to a fixing plate 65 at the bottom of the lifting frame 61. A spring 66 is fixedly connected between the top of the fixing plate 65 and the bottom of the lifting frame 61. The lifting frame 61 is fixedly connected to the lifting plate 45 through the rod.

[0034] By adopting the above technical solution, when the motor 42 drives the rotating shaft 43 to rotate, the lifting frame 61 can rotate accordingly. Since the fixed rod 63 is fixed to the partition plate 41, relative movement can occur between the fixed rod 63, the rotating part 64 and the lifting frame 61. The design of the rotating part 64 to rotate helps to reduce the friction of the movement.

[0035] When one side of the tooth groove 62 is tilted while the other side is not tilted, when the rotating shaft 43 rotates the lifting frame 61, the rotating shaft 43 rotates in the clockwise direction shown in the attached diagram of the instruction manual. This allows the rotating component 64 to be positioned inside the tooth groove 62. As the lifting frame 61 rotates, the rotating component 64 uses the tilt of the tooth groove 62 to limit the lifting frame 61. At this time, the lifting frame 61 gradually moves downward with the rod and the lifting plate 45.

[0036] As the lifting frame 61 rotates, the rotating part 64 is positioned at the top of the lifting frame 61 and is about to reach the next tooth groove 62. Since this side of the tooth groove 62 is not tilted, the rod and the lifting plate 45 can move upward rapidly under the elastic force of the spring 66.

[0037] The partition 41 is equipped with a shaking component 7. The shaking component 7 includes a groove 71 opened at the top of the partition 41. A top plate 72 is slidably connected inside the groove 71. An elastic membrane 73 is fixedly connected to the top of the top plate 72. The outer side of the elastic membrane 73 is fixedly connected to the inner side of the groove 71. An annular groove 74 is opened at the bottom of the partition 41. A bending frame 75 is fixedly connected to the outer side of the lifting frame 61. The bending frame 75 is in a vertical position and passes through the annular groove 74. The design of the elastic membrane 73 ensures the sealing of the top plate 72. The elastic force of the spring 66 is much greater than the elastic force of the elastic membrane 73.

[0038] It should be noted that when the rotating component 64 is at the top of the lifting frame 61, the lifting plate 45 is at a lower position, and at this time the top of the bending frame 75 does not contact the top plate 72.

[0039] By adopting the above technical solution, when the lifting frame 61 rotates, the curved frame 75 rotates accordingly. Under the action of the lifting component 6, the lifting frame 61 can move up and down continuously. When the rotating component 64 enters the next tooth groove 62 from the non-inclined position, the lifting frame 61 carries the curved frame 75 and moves upward quickly. The top of the curved frame 75 squeezes the bottom of the top plate 72, which can make the top plate 72 move upward, thereby making the top plate 72 lift up the chicken manure on top. This further facilitates the shaking of the chicken manure piled below, improves the mixing effect of chicken manure, and thus further improves the mixing effect of chicken manure and bacterial agent, and improves the quality of chicken manure fermentation.

[0040] It should be noted that when the output shaft of the hydraulic rod 12 extends out of the sealing plate 11 to seal the trough 10, the bottom of the sealing plate 11 is higher than the bottom of the top plate 72. When the bending frame 75 rises, it will not squeeze the sealing plate 11. When it is necessary to discharge the chicken manure on the partition 41, the bending frame 75 needs to be rotated away from the trough 10 by rotating the shaft 43 to drive the lifting frame 61.

[0041] It should be noted that the amount of chicken manure added at one time is not large, the thickness of the pile is small, and the number of grooves 71 and top plates 72 is set to be large, so that the amount of chicken manure on a single top plate 72 is small, ensuring that the chicken manure can be shaken up smoothly by the elasticity.

[0042] No top plate 72 is installed at the location of the drop chute 10.

[0043] A motion frame 9 is slidably connected to the top outer wall of the rotating shaft 43. A long rod 8 is fixedly connected to the outer ring array of the motion frame 9. A pulling frame 13 is fixedly connected to the end of the long rod 8. A mounting frame 57 is fixedly connected to the inner side of the tank 1 near the spray pipe 55. An angle tube 58 is rotatably connected to the inner side of the mounting frame 57. A hose 59 is fixedly inserted between the angle tube 58 and the spray pipe 55. The pulling frame 13 contacts the angle tube 58. The motion frame 9 is fixedly connected to the lifting plate 45.

[0044] By adopting the above technical solution, when the lifting plate 45 moves upward, the motion frame 9 moves upward accordingly, which can make the long rod 8 move upward. At this time, the pulling frame 13 pulls the angle tube 58, which facilitates the change of the angle tube 58.

[0045] It should be noted that when the lifting plate 45 moves downward, the moving frame 9 moves downward as well, which allows the long rod 8 to move downward. When the pulling frame 13 moves downward as well, the angle tube 58 shifts downward under the action of gravity, so that the pulling frame 13 is always in contact with the angle tube 58.

[0046] This design allows for adjustment of the spray angle of the diluted bacterial solution, which facilitates spraying the solution to different locations. This further enhances the mixing effect between the bacterial agent and chicken manure, thereby improving the fermentation effect of the chicken manure.

[0047] Example 2: The technical solution of this example differs from that of Example 1 in that: Figures 1 to 6 and Figure 14 An agitator 511 is rotatably connected inside the liquid tank 51. A lifting shaft 512 is movably connected to the bottom of the agitator 511. The outer side of the lifting shaft 512 is slidably connected to the liquid tank 51. The bottom of the lifting shaft 512 is fixedly connected to one of the long rods 8. A second spiral groove 513 is provided on the outer side of the lifting shaft 512. A second guide slider 510 is rotatably connected inside the agitator 511. The second guide slider 510 moves inside the second spiral groove 513. A flexible membrane is fixed between the lifting shaft 512 and the liquid tank 51 to prevent liquid leakage.

[0048] By adopting the above technical solution, when the long rod 8 moves up and down, the lifting shaft 512 can move up and down accordingly, which can generate relative movement between the lifting shaft 512 and the stirring frame 511. At this time, the second guide slider 510 moves inside the second spiral groove 513, which can make the stirring frame 511 rotate, thereby making the stirring frame 511 mix the diluted bacterial agent with water, preventing the bacterial agent from precipitating before being added to the chicken manure, which would lead to uneven concentration, thereby further improving the mixing effect of the bacterial agent and the chicken manure, and further improving the mixing effect of the chicken manure.

[0049] A method for preparing organic fertilizer from chicken manure through fermentation includes the following steps: S1. Premixing: Before fermentation, the microbial agent to be used is diluted with water, and then the diluted microbial agent is placed into the liquid tank 51. The method of placement includes, but is not limited to, conveying through a pipeline. Then, the chicken manure to be fermented is added into the tank 1 through the feeding component 3 from the inlet 2. During this process, the output shaft of the hydraulic rod 12 extends, so that the sealing plate 11 seals the drop trough 10. The chicken manure that has just been added is located above the partition 41. The output shaft of the motor 42 drives the rotating shaft 43 to rotate, which can make the scraper 44 rotate to stir the chicken manure that has just been added and add the microbial agent for premixing. S2. Fermentation: After the chicken manure is premixed with the diluted bacterial agent, the output shaft of the hydraulic rod 12 contracts, so that the sealing plate 11 does not block the trough 10. As the scraper 442 scrapes the chicken manure, the chicken manure falls from the trough 10 into the tank 1 below the partition 41 for fermentation.

[0050] Working principle: The liquid pump inside the inlet pipe 53 is activated, and the diluted bacterial agent inside the liquid tank 51 enters the ring frame 52 through the inlet pipe 53. Then, high-speed, high-pressure air is added from the air inlet pipe via an external air source. The air enters the air inlet ring 54 and then the spray pipe 55. At this time, the air in the spray pipe 55 flows at high speed. According to Bernoulli's principle, the faster the flow rate, the lower the static pressure of the fluid. The diluted bacterial agent inside the ring frame 52 rises through the suction pipe and enters the nozzle to mix with the high-speed airflow, causing the bacterial agent to be sprayed out in a liquid mist state towards the chicken manure. Because the diluted bacterial agent has a large volume and is sprayed onto the newly added chicken manure in a mist form, the rotation of the fixed ring 441 causes the scraper 442 to rotate accordingly, facilitating the cleaning of the baffle 4. The chicken manure at the top is stirred, and the rotating shaft 443 and stirring plate 444 rotate accordingly. Since the lifting plate 45 can move up and down continuously, when the lifting plate 45 moves downward with the inclined groove 46, the inclined block 47 can move with the small rod 48 towards the rotating shaft 443 under the action of the inclined setting. At this time, the small rod 48 and the rotating shaft 443 generate relative motion, so that the first guide slider 410 moves inside the first spiral groove 49, so that the rotating shaft 443 carries the stirring plate 444 to rotate around the axis of the rotating shaft 443. Multiple stirring plates 444 turn the chicken manure, which is conducive to turning the chicken manure at the bottom to the upper position, thereby further facilitating the uniform mixing between the inoculant and the chicken manure, and further improving the fermentation quality.

[0051] When the lifting frame 61 rotates, the curved frame 75 rotates accordingly. Under the action of the lifting assembly 6, the lifting frame 61 can move up and down continuously. When the rotating part 64 enters the next tooth groove 62 from the non-inclined part, the lifting frame 61 carries the curved frame 75 and moves upward quickly. The top of the curved frame 75 squeezes the bottom of the top plate 72, which can make the top plate 72 move upward, thereby making the top plate 72 lift up the chicken manure on top. This further facilitates the shaking of the chicken manure piled below, improves the mixing effect of chicken manure, and thus further improves the mixing effect of chicken manure and bacterial agent, and improves the quality of chicken manure fermentation.

[0052] When the lifting plate 45 moves upward, the moving frame 9 moves upward as well, which allows the long rod 8 to move upward. At this time, the pulling frame 13 pulls the angle tube 58, which facilitates the change of the angle tube 58's angle. It should be noted that when the lifting plate 45 moves downward, the moving frame 9 moves downward as well, which allows the long rod 8 to move downward. When the pulling frame 13 moves downward as well, the angle tube 58 shifts downward under the action of gravity, so that the pulling frame 13 is always in contact with the angle tube 58. This design allows for adjustment of the angle of the diluted bacterial solution spray, which is beneficial for spraying the bacterial solution to different positions. This can further improve the mixing effect of the bacterial agent and chicken manure, and further improve the fermentation effect of the chicken manure.

[0053] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
