Description

Technical Field

[0001] The present invention relates to the technical field of biological excrement treatment, and in particular to intelligent livestock and poultry excrement treatment equipment and method. Background Art

[0002] With the rapid development of animal husbandry, the problem of livestock and poultry manure treatment has become increasingly prominent. As an important by-product in the agricultural production process, improper treatment of livestock and poultry manure will not only cause serious pollution to the environment, but also affect the health of humans and animals. Therefore, the development of efficient and environmentally friendly livestock and poultry manure treatment equipment has become an important issue in the current development of animal husbandry. Livestock and poultry manure treatment uses the life activities of organisms such as microorganisms or insects to convert organic matter in manure into stable humus or biomass. This type of technology has the advantages of environmental protection and resource utilization, and is currently the mainstream direction of livestock and poultry manure treatment.

[0003] In recent years, the technology of biological treatment of livestock and poultry manure using black soldier fly larvae has gradually attracted attention. The black soldier fly (Hermetia illucens L.), scientifically known as Hermetia illucens, is a saprophytic insect of the family Soldierfly. Its larvae feed on animal manure, rotten organic matter and kitchen waste. It has the advantages of high conversion rate, small impact on the environment, low cost and low requirements for site equipment. The technology of using black soldier fly larvae to treat livestock and poultry manure is to release black soldier fly larvae into the manure, and use the feeding and digestion of the larvae to decompose the organic matter in the manure into insect protein and a small amount of residue. In this process, the black soldier fly larvae can not only effectively reduce the COD, BOD, ammonia nitrogen, phosphorus, potassium and other nutrient-rich substances in the manure, but also can be converted into nutrients required by themselves through metabolism, such as insect protein. In addition, black soldier fly larvae can effectively control the breeding of competing dipteran insects such as houseflies, reduce the base number of harmful microorganisms in feces, and detoxify heavy metals in feces, reducing heavy metal pollution to the environment.

[0004] Although the technology of biological treatment of livestock and poultry manure using black soldier fly larvae has shown many advantages, such as efficient conversion, environmental protection, and resource utilization, in actual application, this technology still faces some shortcomings that cannot be ignored. The following is a detailed analysis of these shortcomings:

[0005] Difficulty in controlling growth time: Black soldier fly larvae grow very fast. If their growth time cannot be strictly controlled, once the larvae grow into adults, they will lose their value as feed or fertilizer raw materials, and may escape due to their ability to fly, increasing the difficulty of management. Therefore, it is necessary to accurately control the feeding cycle of the larvae to ensure that they are collected and processed within the optimal harvest period.

[0006] Larvae batch management is complex: During continuous culture, newly added feces and larvae are difficult to effectively distinguish from larvae cultured earlier, which may lead to problems such as different growth rates and uneven nutrient absorption of larvae. In addition, cross-contamination between batches may also affect the quality and safety of the final product. Therefore, it is necessary to establish a scientific batch management system to ensure the independence and consistency of each batch of larvae.

[0007] Difficult to achieve continuous culture: Due to the growth cycle of black soldier fly larvae and the limitation of feces treatment efficiency, it is difficult to achieve true continuous culture in practical application. This not only affects the treatment efficiency, but also increases the complexity and cost of manual operation. Therefore, it is necessary to further optimize the culture process and equipment design to achieve more efficient and stable continuous culture.

[0008] Uneven distribution of larvae and feces: During the feeding process, larvae and feces are prone to uneven distribution, resulting in local accumulation. This will not only affect the growth rate and health of the larvae, but may also lead to the generation of harmful gases and increased odor. Therefore, appropriate stirring and ventilation measures are required to ensure uniform distribution and good ventilation of larvae and feces.

[0009] Harmful gases and odors: Although black soldier fly larvae can effectively reduce the content of harmful substances in feces, some harmful gases (such as ammonia, hydrogen sulfide, etc.) and odors may still be produced during the treatment process. These gases and odors will not only pollute the environment, but may also affect the quality of life of surrounding residents. Therefore, effective deodorization and gas purification measures need to be taken to ensure the environmental protection and safety of the treatment process.

[0010] It is necessary to provide an intelligent livestock and poultry manure processing device and method to solve the problems raised in the above background technology. Summary of the invention

DETAILED DESCRIPTION

[0050] See also Figure 1-Figure 6 In an embodiment of the present invention, an intelligent livestock and poultry excrement treatment device includes: a breeding house 1, wherein a circular guide rail 2 is disposed at the top and the bottom of the breeding house 1;

[0051] A plurality of sliders 21, wherein the sliders 21 are slidably disposed in the annular guide rail 2, and a breeding bracket 3 is fixedly connected between the upper and lower sliders 21, and the breeding bracket 3 has a plurality of breeding basins 8 for placing livestock and poultry excrement distributed above and below;

[0052] An automatic door 6 is provided at one side of the breeding room 1 and can be opened and closed automatically to facilitate entry and exit of the breeding basin 8;

[0053] The larvae box 5 is fixed above the front side of the breeding room 1 near the automatic door 6. A main channel 51 is connected below the larvae box 5. The main channel 51 is further divided into a plurality of branch channels 52. Each branch channel 52 runs through the inside of the breeding room 1. The outlet height of each branch channel 52 is set to correspond to the top of each breeding basin 8 in the breeding rack 3.

[0054] A quantitative dispensing valve 53 is installed in each branch channel 52;

[0055] The breeding basins 8 filled with feces are placed in the breeding brackets 3 from the automatic door 6 in sequence. The breeding brackets 3 move along the annular guide rail 2 with the slider 21 to the exit of the branch channel 52 of the larva box 5. The black soldier fly larvae fall into each breeding basin 8 from the branch channel 52. The breeding brackets 3 in the annular guide rail 2 move a fixed unit a day. When the breeding brackets 3 where the breeding basins 8 are placed on the first day rotate one circle to the position of the automatic door 6, the breeding basins 8 that have been completed are moved out.

[0056] The gantry 4 is fixed on one side of the breeding room 1 near the automatic door 6. A slide 41 is provided in the gantry 4 for sliding up and down. Two telescopic forks 42 are provided in the slide 41. By sliding the slide 41 up and down and extending the telescopic forks 42, the breeding basin 8 in the breeding bracket 3 can be transferred to the outside, so that the breeding basin 8 can be loaded and unloaded.

[0057] In this embodiment, a turntable 22 is rotatably provided at both ends of the inner side of each of the annular guide rails 2, and the two turntables 22 of the same annular guide rail 2 are connected together by a belt 23, and the slider 21 in each of the annular guide rails 2 is fixedly connected to the belt 23 in the annular guide rail 2;

[0058] The upper and lower concentric rotating disks 22 are connected together via a rotating shaft, and one of the rotating shafts is connected to a driving motor.

[0059] The driving motor can drive the belts 23 in the two annular guide rails 2 to move synchronously, so that each slider 21 moves synchronously to drive the breeding support 3 to move.

[0060] In this embodiment, an exhaust fan 7 is provided above the breeding room 1, and the outlet of the exhaust fan 7 is connected to an air processor 71. The exhaust fan 7 can ensure that the air in the breeding room 1 remains fresh, and the exhaust gas can be cleaned by the air processor 71 to avoid polluting the external air.

[0061] Please refer to Figure 4 and Figure 5In this embodiment, a plurality of pairs of support plates 31 are distributed on both sides of the breeding bracket 3, and the support plates 31 are used to place the breeding basin 8;

[0062] A connecting bar 34 is arranged above each breeding basin 8 , and a stirring rod 35 is rotatably arranged below the connecting bar 34 .

[0063] The stirring rod 35 can stir the material in the breeding basin 8 below it, so that the feces and larvae are evenly distributed, pile-up is avoided, contact with air is promoted, and larval vitality is improved.

[0064] In this embodiment, slide grooves 32 are provided on both sides of the breeding support 3, and a plurality of cross bars 33 are slidably connected in the slide grooves 32, and the two cross bars 33 on both sides are connected together by the connecting strips 34.

[0065] That is to say, the connecting strip 34 can slide up and down, so that the stirring rod 35 can move up and down, so that the stirring rod 35 can leave the height of the breeding basin 8 to avoid hindering the loading and unloading of the breeding basin 8.

[0066] In this embodiment, a horizontal connecting shaft 36 is rotatably connected to the connecting bar 34 , and the connecting shaft 36 is connected to the stirring rod 35 via a bevel gear set 37 .

[0067] The stirring rod 35 can be driven to rotate by rotating the connecting shaft 36 .

[0068] See also Figure 6 In this embodiment, a ring-shaped side wall plate 9 is fixed to the inner wall of the ring guide rail 2, and a plurality of ring-shaped guide grooves 91 are distributed in the upper and lower parts of the side wall plate 9;

[0069] Each of the connecting shafts 36 is slidably embedded in the guide groove 91 .

[0070] In this embodiment, a gear 38 is fixed to the end of the connecting shaft 36 , a rack is provided at the bottom of each guide groove 91 , and the gear 38 is meshed with the rack.

[0071] When the breeding support 3 moves along the annular guide rail 2, the connecting shaft 36 also slides along the guide groove 91, so that the gear 38 drives the connecting shaft 36 to rotate under the action of the rack, thereby rotating the stirring rod 35;

[0072] That is to say, whenever the breeding support 3 moves along the annular guide rail 2, the stirring rod 35 will rotate to evenly mix the feces and larvae in the breeding basin 8, ensuring that the material distribution is re-stirred every time the breeding support 3 moves to the next fixed unit, ensuring that the larvae can come into contact with feces in other parts and fresh air.

[0073] Each guide groove 91 rises in height near the automatic door 6 .

[0074] That is to say, whenever the breeding support 3 moves to the position of the automatic door 6, the connecting shaft 36 will rise, thereby raising the connecting bar 34 and the stirring rod 35, and making the stirring rod 35 leave the height of the breeding basin 8 to avoid hindering the loading and unloading of the breeding basin 8.

[0075] In this embodiment, triangular handles 81 are fixed on both sides of the breeding basin 8;

[0076] The two ends of the crossbar 33 are rotatably connected with vertical guide wheels 39 , and when the connecting strip 34 moves downward, the guide wheels 39 are respectively fitted with the two waists of the triangular handle 81 on the same side.

[0077] That is to say, when the breeding basin 8 newly placed on the breeding bracket 3 is not concentric with the stirring rod 35, after the connecting strip 34 moves down, since the guide wheel 39 fits with the waists of the triangular handle 81 on the same side, the guide wheel 39 will push the triangular handle 81 to automatically align, so that after the connecting strip 34 moves down, the breeding basin 8 and the stirring rod 35 are concentric, ensuring that the stirring rod 35 can smoothly enter the breeding basin 8.

[0078] A method for treating livestock and poultry manure using intelligent livestock and poultry manure treatment equipment comprises the following steps:

[0079] a. The breeding pots filled with feces 8 are placed in the corresponding positions of the breeding bracket 3 through the automatic door 6 in sequence;

[0080] b. Start the drive motor, drive the slider 21 and the breeding bracket 3 along the annular guide rail 2 through the belt 23 and the turntable 22, so that the breeding bracket 3 is moved to the outlet of the branch channel 52 of the larvae box 5 in sequence, and the black soldier fly larvae are released into each breeding basin 8 through the quantitative delivery valve 53;

[0081] c. The breeding bracket 3 continues to move along the circular guide rail 2, moving a fixed unit every day, and the stirring rod 35 on the connecting bar 34 rotates automatically under the action of the guide groove 91 and the rack on the inner side of the circular guide rail 2 to stir the feces and larvae in the breeding basin 8 to ensure uniform distribution of the material;

[0082] d. When the breeding basin 8 filled with feces rotates with the breeding bracket 3 back to the automatic door 6 position, the use of the gantry 4 on the slide 41 and the telescopic fork 42 will be completed breeding basin 8 out of the breeding room 1, while replacing the new breeding basin 8 filled with feces;

[0083] e. During the breeding process, the air in the breeding room 1 is kept fresh by the exhaust fan 7 and the air processor 71 to avoid exhaust gas pollution of the external environment;

[0084] f. Repeat steps a to d to achieve continuous processing of livestock and poultry manure and continuous cultivation of larvae.

[0085] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto.
