Technical Field
[0001] This invention relates to the field of agricultural breeding technology, and in particular to a device that facilitates the treatment of chicken manure by black soldier flies. Background Technology
[0002] Chicken manure, a major waste product generated during livestock and poultry farming, is complex in composition and rich in organic matter. Improper handling can easily create a breeding ground for pathogenic microorganisms. These microorganisms include pathogenic bacteria such as Escherichia coli, Salmonella, and Staphylococcus aureus, as well as parasite eggs such as Ascaris lumbricoides and Coccidia trachomatis. They can spread through air, water, or soil, causing zoonotic diseases and leading to environmental problems such as eutrophication and soil degradation. Therefore, efficiently and safely treating chicken manure and interrupting the transmission chain of pathogenic microorganisms has become a key challenge in the resource utilization of agricultural waste. Black soldier flies, as saprophytic insects, exhibit significant advantages in controlling pathogenic microorganisms when treating chicken manure due to their unique biological characteristics, providing an innovative solution to this problem.
[0003] Existing black soldier fly larvae-based chicken manure treatment devices mainly consist of a chicken manure pretreatment unit, a black soldier fly breeding unit, and a fly-feces separation unit. Their working principle is as follows: chicken manure is simply crushed and humidified before being fed into the breeding unit. Black soldier fly larvae consume the manure and convert it into protein. The remaining fly-feces are collected through the separation unit. These devices achieve chicken manure reduction through the rapid biodegradation by black soldier flies (the treatment cycle can be shortened to 7-15 days). However, the pretreatment unit has shortcomings: simple crushing cannot guarantee the uniformity of chicken manure particle size; larger chicken manure particles are difficult to completely remove pathogens when heated, resulting in some chicken manure not being effectively treated, affecting the overall reduction effect and hindering black soldier fly growth. Therefore, a device that facilitates black soldier fly larvae-based chicken manure treatment is proposed. Summary of the Invention
[0004] The purpose of this invention is to provide a device that facilitates the treatment of chicken manure by black soldier flies. It can simultaneously achieve the mixing, crushing, heating and dropping of chicken manure. After the chicken manure has undergone the above-mentioned heating, crushing and mixing pretreatment, pathogens are effectively killed, and its physical state and temperature conditions are suitable for the growth of black soldier flies.
[0005] The above-mentioned technical objective of the present invention is achieved through the following technical solution: a device for facilitating the treatment of chicken manure by black soldier flies, comprising a breeding box, wherein a pretreatment mechanism is provided at the top of the breeding box, the pretreatment mechanism comprising a perforated pretreatment box fixedly connected to the breeding box, wherein a heating mechanism and a crushing and stirring assembly are provided inside the perforated pretreatment box, the crushing and stirring assembly comprising a stirring element, a driver, and a crushing element located at the bottom of the perforated pretreatment box, wherein the drive shaft of the driver is fixedly connected to the top of the stirring element, and the bottom end of the stirring element is connected to the top of the crushing element through a transmission mechanism, the transmission mechanism comprising multiple grooves formed on the side wall of the crushing element, and a first transmission plate rotatably connected to the inside of the grooves, and further comprising multiple second transmission plates fixedly connected to the outer surface of the stirring element, wherein when the driver drives the stirring element to rotate clockwise, the second transmission plates separate from each other, and the driver only drives the stirring element to rotate and stir the chicken manure, and when the driver rotates counterclockwise, the first transmission plate and the second transmission plate engage with each other, and through the transmission action of the first transmission plate and the second transmission plate, the crushing element is driven to rotate and crush the chicken manure.
[0006] The electric heating element (PTC thermostatic heating tube) of the heating mechanism is connected to a 220V power supply, and the heating temperature is set between 75°C and 80°C. When powered on, the PTC thermostatic heating tube generates heat, which is dissipated into the perforated pretreatment box through heat transfer to heat the chicken manure inside, achieving a brief temperature rise. Simultaneously, the driver is activated. When the driver rotates clockwise, the second transmission plate separates from itself. The driver only drives the agitator to rotate and agitate the chicken manure, while the crusher remains stationary relative to the perforated pretreatment box, thus blocking the holes in the box. The agitator stirs the chicken manure inside the box, causing it to tumble and increasing the overall contact between the manure and heat. This process is achieved through the transmission mechanism and... The mixing components are connected. When the driver rotates counterclockwise, the second transmission plate rotates counterclockwise as well. Through the transmission action with the first transmission plate, the first and second transmission plates mesh with each other. Through the transmission action of the first and second transmission plates, the crushing components are driven to rotate counterclockwise to crush the chicken manure. The operation of the crushing components and the linkage with the mixing components further enable the crushed chicken manure to come into more full contact with heat. During the crushing process, the crushing components do not block the holes of the perforated pretreatment box, allowing the chicken manure to fall into the feeding box inside the breeding box. At the same time, the chicken manure is stirred, crushed, heated, and falls. After the above heating, crushing, stirring, and pretreatment, the pathogens in the chicken manure are effectively killed, and its physical state and temperature conditions are suitable for the growth of black soldier fly larvae.
[0007] A further configuration of the present invention is as follows: the stirring component includes a rotating shaft and a plurality of stirring blades fixedly connected to the outer surface of the rotating shaft, the stirring blades having an angle of 30°-60° with the horizontal plane; the crushing component includes a rotating drum rotatably connected to the bottom of a pretreatment box with holes at the bottom, and a plurality of crushing blades fixedly connected to the outer surface of the rotating drum.
[0008] By adopting the above technical solution, the driver drives the rotating shaft, which in turn drives the rotating drum to rotate through the transmission mechanism. This causes the stirring blades to stir the chicken manure, and the crushing blades to crush the chicken manure. The structural design of the stirring and crushing components allows the chicken manure to be stirred during the pretreatment process, increasing the frequency and range of stirring and allowing the chicken manure to fully contact with heat. At the same time, the chicken manure is crushed by the crushing blades, reducing the size of the chicken manure particles and increasing the contact area between the chicken manure and heat, thereby improving the pretreatment effect and creating more favorable conditions for black soldier fly treatment.
[0009] A further feature of the present invention is that the hole in the perforated pretreatment box is formed at its bottom and is located below the crushing blade.
[0010] By adopting the above technical solution, after the crusher breaks down the chicken manure, the pre-treated chicken manure can be discharged through the holes at the bottom and enter the breeding box for black soldier flies to feed on. This design allows the crushed chicken manure to fall smoothly, while avoiding the direct discharge of uncrushed or insufficiently crushed chicken manure, ensuring that the chicken manure entering the breeding box reaches the appropriate particle size, further increasing the contact area between the chicken manure and heat, and improving the pre-treatment effect.
[0011] A further feature of the present invention is that the heating mechanism includes a temperature-conducting ring plate that is vertically fixed to the inner side wall of the bottom perforated pretreatment box, and a plurality of PTC constant temperature heating tubes are disposed inside the temperature-conducting ring plate, wherein the central axis of the PTC constant temperature heating tubes is perpendicular to the central axis of the temperature-conducting ring plate.
[0012] By adopting the above technical solution, the arrangement of the central axis of the PTC constant temperature heating tube perpendicular to the central axis of the temperature conducting ring plate increases the contact area with chicken manure and improves heating efficiency. This arrangement allows the heat generated by the PTC constant temperature heating tube to be transferred to the chicken manure more evenly, ensuring that the chicken manure is heated evenly as a whole, improving the heating effect, providing good conditions for subsequent black soldier fly treatment, and ensuring that the pathogens are effectively killed.
[0013] A further feature of the present invention is that the temperature-conducting ring plate is made of stainless steel, the wall thickness of the temperature-conducting ring plate is 10-15mm, the diameter of the PTC constant temperature heating tube is 5-10mm, and the spacing between adjacent PTC constant temperature heating tubes is 30-50mm.
[0014] By adopting the above technical solution, the temperature-conducting ring plate is made of stainless steel. Utilizing the thermal conductivity and corrosion resistance of stainless steel, the heat from the PTC constant-temperature heating tube is effectively transferred to the chicken manure. The specified wall thickness of the temperature-conducting ring plate, the diameter of the PTC constant-temperature heating tube, and the spacing between adjacent PTC constant-temperature heating tubes are designed to ensure uniform and efficient heat transfer to the chicken manure, while also considering the cost and structural rationality of the device. The stainless steel temperature-conducting ring plate is corrosion-resistant and has a long service life, ensuring long-term stable operation of the device. The reasonable design of the wall thickness, diameter, and spacing ensures uniform heating of the chicken manure, improves heating efficiency, ensures the pretreatment effect, and avoids energy waste and overly complex device structure.
[0015] A further feature of the present invention is that the number of stirring blades is 2-4, the length of the stirring blades is 300-500mm, the stirring blades are perpendicular to the axis of the rotating shaft, and the thickness of the stirring blades is 5-10mm.
[0016] By adopting the above technical solution, the design of the number, length, perpendicularity to the axis of rotation, and thickness of the stirring blades is intended to ensure that the stirring blades can effectively stir the chicken manure when the shaft rotates, increasing the frequency and range of manure agitation, allowing the manure to fully contact with heat and crushing blades, thus improving the pretreatment effect. A reasonable number of stirring blades can ensure comprehensive stirring, and a certain length can expand the stirring range. The perpendicularity to the axis of rotation ensures the stability of stirring, and the appropriate thickness gives the stirring blades sufficient strength and stirring capacity, improving the uniformity and efficiency of chicken manure pretreatment.
[0017] A further feature of the present invention is that the number of the crushing blades is 6-12, the length of the crushing blades is 300-500mm, the crushing blades are welded to the outer surface of the rotating drum, and the blades of the crushing blades form an angle of 30°-60° with the horizontal plane.
[0018] By adopting the above technical solution, an appropriate number of crushing blades can be used to thoroughly crush chicken manure; a certain length of crushing blades can expand the crushing range; welding connection ensures the connection between the crushing blades and the rotating drum; and a specific blade angle design allows the crushing blades to cut into the chicken manure better during rotation, improving crushing efficiency and providing black soldier flies with finer and more uniform feed.
[0019] A further feature of the present invention is that the first transmission plate and the second transmission plate are both made of carbon steel, the length of the first transmission plate and the second transmission plate is in the range of 5-10mm, and the first transmission plate is rotatably connected to the groove by a hinge.
[0020] By adopting the above technical solution, the first transmission plate and the second transmission plate are made of carbon steel and are set to a certain length. When the driver rotates in different directions, the two interact to achieve transmission. The carbon steel material has a certain strength and wear resistance, which ensures the stability and durability of the first transmission plate and the second transmission plate during the transmission process. The appropriate length design helps to achieve effective transmission. The hinge rotation connection allows the first transmission plate to rotate flexibly to meet the transmission requirements under different rotation directions.
[0021] The beneficial effects of this invention are: 1. When the driver rotates clockwise, the stirring component stirs the chicken manure, causing it to tumble in the perforated pretreatment box, increasing the overall contact area between the chicken manure and heat, ensuring that the chicken manure is heated evenly, improving the heating treatment effect, and further enhancing the pathogen killing efficiency. When the driver rotates counterclockwise, the transmission mechanism drives the crushing component to rotate counterclockwise, crushing the chicken manure. The crushed chicken manure particles become smaller, and their physical state is improved, which is more conducive to the feeding and digestion of black soldier flies, promoting the growth of black soldier flies.
[0022] 2. The crushing and mixing components are connected by a transmission mechanism, realizing the linkage of crushing and mixing functions. During the crushing process, the crushing components do not block the holes of the perforated pretreatment box, allowing chicken manure to fall smoothly into the feeding box inside the breeding box, ensuring the continuity and efficiency of the entire processing process, and completing multiple processing steps without additional operation.
[0023] 3. The design of the crushing and mixing component ensures that the chicken manure is fully mixed and crushed during the pretreatment process. The mixing action increases the contact area between the chicken manure and heat, making the heating more uniform and rapid. The crushing action reduces the size of the chicken manure particles, further improving the contact efficiency between the chicken manure and heat and other treatment factors, thereby shortening the pretreatment time and improving the efficiency of the entire chicken manure treatment process.

[0027] The technical solution of the present invention will now be clearly and completely described with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.
[0028] Reference Figures 1-9A device for facilitating the treatment of chicken manure by black soldier flies includes a breeding box 1. A pretreatment mechanism is installed at the top of the breeding box 1. The pretreatment mechanism includes a perforated pretreatment box 18 fixedly connected to the breeding box 1. A heating mechanism 16 and a crushing and mixing assembly are installed inside the perforated pretreatment box 18. The crushing and mixing assembly includes a mixing element 14, a driver 13, and a crushing element 15 located at the bottom of the perforated pretreatment box 18. The drive shaft of the driver 13 is fixedly connected to the top of the mixing element 14. The bottom end of the mixing element 14 is connected to the top of the crushing element 15 via a transmission mechanism 17. The transmission mechanism 17 includes components located on the side of the crushing element 15. The wall has multiple grooves 1701, and a first transmission plate 1702 rotatably connected inside the grooves 1701. It also includes multiple second transmission plates 1704 fixedly connected to the outer surface of the stirring member 14. When the driver 13 drives the stirring member 14 to rotate clockwise, the second transmission plates 1704 separate from each other, and the driver 13 only drives the stirring member 14 to rotate and stir the chicken manure. When the driver 13 rotates counterclockwise, the first transmission plate 1702 and the second transmission plate 1704 mesh with each other. Through the transmission action of the first transmission plate 1702 and the second transmission plate 1704, the crushing member 15 is driven to rotate and crush the chicken manure. The electric heating element (PTC constant temperature heating tube 1602) of the heating mechanism 16 is connected to a 220V power supply, and the heating temperature is set between 75°C and 80°C. When powered on, the PTC constant temperature heating tube 1602 generates heat, which is dissipated into the perforated pretreatment box 18 through heat transfer to heat the chicken manure inside the box, achieving a brief temperature rise. At the same time, the driver 13 is started. When the driver 13 rotates clockwise, the second transmission plate 1704 separates from itself. The driver 13 only drives the agitator 14 to rotate and agitate the chicken manure. The crusher 15 remains stationary relative to the perforated pretreatment box 18, thus blocking the holes in the perforated pretreatment box 18. The agitator 14 agitates the chicken manure inside the perforated pretreatment box, causing the chicken manure to tumble inside the box, increasing the comprehensive contact between the chicken manure and the heat. This is achieved through the transmission mechanism 17 and... The agitator 14 is connected. When the driver 13 rotates counterclockwise, the second transmission plate 1704 rotates counterclockwise as well. Through the transmission action with the first transmission plate 1702, the first transmission plate 1702 and the second transmission plate 1704 mesh with each other. Through the transmission action of the first transmission plate 1702 and the second transmission plate 1704, the crusher 15 is driven to rotate counterclockwise to crush the chicken manure. The crusher 15 works and is linked with the agitator 14, which further makes the crushed chicken manure come into more full contact with heat. During the crushing process, the crusher 15 does not block the holes of the perforated pretreatment box 18, so that the chicken manure can fall into the feeding box 6 inside the breeding box 1. At the same time, the chicken manure is agitated, crushed, heated and falls. After the above heating and crushing agitation pretreatment, the pathogens of the chicken manure are effectively killed, and its physical state and temperature conditions are suitable for the growth of black soldier fly larvae.
[0029] The mixing component 14 includes a rotating shaft 1401 and several mixing blades 1402 fixedly connected to the outer surface of the rotating shaft 1401. The angle between the mixing blades 1402 and the horizontal plane is 30°-60°. The crushing component 15 includes a rotating drum 1501 rotatably connected to the bottom of the pretreatment box 18 with holes at the bottom. Multiple crushing blades 1502 are fixedly connected to the outer surface of the rotating drum 1501. The driver 13 drives the rotating shaft 1401, and the rotating shaft 1401 drives the rotating drum 1501 to rotate through the transmission mechanism 17, thereby causing the mixing blades 1402 to mix chicken manure and the crushing blades 1502 to crush chicken manure. The structural design of the mixing component 14 and the crushing component 15 enables the chicken manure to be mixed during the pretreatment process, increasing the frequency and range of chicken manure turning, so that the chicken manure can fully contact the heat, and also crush the chicken manure through the crushing blades 1502 to reduce the size of chicken manure particles, further increasing the contact area between chicken manure and heat, improving the pretreatment effect, and creating more favorable conditions for black soldier fly treatment.
[0030] The heating mechanism 16 includes a temperature-conducting ring plate 1601 that is vertically fixed to the inner wall of the perforated pretreatment box 18 at the bottom. Multiple PTC constant-temperature heating tubes 1602 are arranged inside the temperature-conducting ring plate 1601. The central axis of the PTC constant-temperature heating tubes 1602 is perpendicular to the central axis of the temperature-conducting ring plate 1601. This arrangement increases the contact area with the chicken manure, improving heating efficiency. It also allows the heat generated by the PTC constant-temperature heating tubes 1602 to be transferred more evenly to the chicken manure, ensuring uniform heating of the entire manure and improving the heating effect. This provides favorable conditions for subsequent black soldier fly treatment, ensuring that the pathogens are effectively killed.
[0031] The temperature-conducting ring plate 1601 is made of stainless steel, with a wall thickness of 10-15mm. The diameter of the PTC constant temperature heating tube 1602 is 5-10mm, and the spacing between adjacent PTC constant temperature heating tubes 1602 is 30-50mm. The stainless steel material of the temperature-conducting ring plate 1601 effectively transfers heat from the PTC constant temperature heating tubes 1602 to the chicken manure, utilizing the thermal conductivity and corrosion resistance of stainless steel. The specified wall thickness of the temperature-conducting ring plate 1601, the diameter of the PTC constant temperature heating tubes 1602, and the spacing between adjacent PTC constant temperature heating tubes 1602 are designed to ensure uniform and efficient heat transfer to the chicken manure, while also considering the cost and structural rationality of the device. The stainless steel temperature-conducting ring plate is corrosion-resistant and has a long service life, ensuring long-term stable operation of the device. The reasonable design of the wall thickness, diameter, and spacing ensures uniform heating of the chicken manure, improves heating efficiency, ensures the pretreatment effect, and avoids energy waste and overly complex device structure.
[0032] The perforated pretreatment box 18 has holes at its bottom, located below the crusher 1502. After the crusher 1502 crushes the chicken manure, the pretreated chicken manure can be discharged through the holes at the bottom and enter the breeding box 19 for black soldier flies to feed on. This design allows the crushed chicken manure to fall smoothly, while avoiding the direct discharge of uncrushed or insufficiently crushed chicken manure. This ensures that the chicken manure entering the breeding box reaches the appropriate particle size, further increasing the contact area between the chicken manure and heat, and improving the pretreatment effect.
[0033] The number of stirring blades 1402 is 2-4, the length of stirring blades 1402 is 300-500mm, the stirring blades 1402 are perpendicular to the axis of the rotating shaft 1401, and the thickness of stirring blades 1402 is 5-10mm. The design of the number, length, perpendicularity to the axis of the rotating shaft 1401, and thickness of stirring blades 1402 is to ensure that the stirring blades 1402 can effectively stir chicken manure when the rotating shaft 1401 rotates, increase the frequency and range of chicken manure agitation, and ensure that chicken manure is in full contact with heat, crushing blades 1502, etc., thereby improving the pretreatment effect. An appropriate number of stirring blades 1402 can ensure the comprehensiveness of stirring, a certain length can expand the stirring range, perpendicularity to the axis of the rotating shaft 1401 can ensure the stability of stirring, and the appropriate thickness can give the stirring blades 1402 sufficient strength and stirring capacity, thereby improving the uniformity and efficiency of chicken manure pretreatment.
[0034] The number of crushing blades 1502 is 6-12, and the length of each crushing blade 1502 is 300-500mm. The crushing blades 1502 are welded to the outer surface of the rotating drum 1501. The blades of the crushing blades 1502 form an angle of 30°-60° with the horizontal plane. An appropriate number of crushing blades 1502 can comprehensively crush chicken manure. A certain length of crushing blades 1502 can expand the crushing range. The welded connection ensures the firmness of the connection between the crushing blades 1502 and the rotating drum 1501. The specific blade angle design allows the crushing blades 1502 to better cut into the chicken manure during rotation, improving crushing efficiency and providing black soldier flies with finer and more uniform feed.
[0035] The first transmission plate 1702 and the second transmission plate 1704 are both made of carbon steel. The length of the first transmission plate 1702 and the second transmission plate 1704 ranges from 5 to 10 mm. The first transmission plate 1702 is rotatably connected to the groove 1701 by a hinge. The depth of the groove 1701 is 1 / 2 to 2 / 3 of the thickness of the side wall of the broken part 15. The first transmission plate 1702 and the second transmission plate 1704 are made of carbon steel and are set with a certain length. When the driver 13 rotates in different directions, the two interact to achieve transmission. The carbon steel material has a certain strength and wear resistance, which ensures the stability and durability of the first transmission plate 1702 and the second transmission plate 1704 in the transmission process. The appropriate length design helps to achieve effective transmission. The hinged rotatable connection allows the first transmission plate 1702 to rotate flexibly to meet the transmission requirements under different rotation directions.
[0036] The driver 13 is a servo motor with a power of 0.5-2kW. The driver 13 is fixedly connected to the top wall of the breeding tank 1 by bolts. The diameter of the rotating shaft 1401 is 20-40mm. The servo motor can precisely control the speed and direction of rotation, providing power to the rotating shaft 1401. The servo motor power of 0.5-2kW can provide sufficient power to drive the rotating shaft 1401 to rotate, meeting the needs of pre-treatment work such as crushing and mixing. The bolted connection ensures the firmness of the connection between the driver 13 and the breeding tank 1. The stable connection helps the transmission process to proceed smoothly. The appropriate diameter of the rotating shaft 1401 ensures the strength of the rotating shaft 1401, which can withstand the load brought by the stirring blade 1402 and the transmission mechanism 17.
[0037] The second transmission plate 1704 is equipped with a roller 1703. When the first transmission plate 1702 and the second transmission plate 1704 interact and transmit power, the roller 1703 can reduce the friction between the two, reduce the energy loss during transmission, improve transmission efficiency, reduce wear on the transmission plates, extend the service life of the first transmission plate 1702 and the second transmission plate 1704, and ensure the long-term stable operation of the device.
[0038] The side wall of the breeding box 1 is equipped with a feeding box 6 and a discharge port 2. The feeding box 6 enters and exits the breeding box 1 through the discharge port 2. The side of the breeding box 1 is equipped with a fan 3 and a heating box 5. The heating box 5 is connected to the breeding box 1. The side of the breeding box 1 is equipped with a water tank 11. The bottom of the water tank 11 is equipped with a drain pipe 9. The drain pipe 9 is equipped with a valve 8. The outlet end of the drain pipe 9 is fixedly connected to an atomizing nozzle 10 and extends into the heating box 5. The heating box 5 is equipped with electric heating plates 7 located on both sides of the atomizing nozzle 10. The electric heating plates 7 are used to heat the water mist entering the heating box 5. During the process of chicken manure falling from the bottom of the perforated pretreatment box 18 into the feeding box 6, the amount of water atomized by the atomizing nozzle 10 in the heating box 5 can be adjusted by manually opening the valve 8, thereby improving the humidity of the chicken manure and further providing a suitable growth environment for black soldier flies.
[0039] The electric heating plate 7 is a stainless steel heating plate, model GRB-01, with a power adjustment range of 0kW to 5kW and an adjustment accuracy of 0.1kW. The stainless steel heating plate has good thermal conductivity and corrosion resistance, and the power adjustment range is wide and highly accurate. The heating power can be precisely adjusted according to actual needs to better control the air temperature entering the chicken manure material and further meet the temperature regulation requirements of the chicken manure material.
[0040] The atomizing nozzle 10 has an atomizing particle size of 50-200μm. The atomizing nozzle 10 atomizes water into water mist with a specific particle size (50-200μm). This particle size of water mist can be more evenly dispersed in the air, fully contact with hot air, be heated quickly, and can be better mixed with chicken manure material to regulate humidity. Water mist with a suitable particle size can improve the uniformity and efficiency of humidity regulation, making the humidity of different parts of the chicken manure material more consistent, and further creating a more suitable growth environment for black soldier flies, which is beneficial to the black soldier flies' treatment of chicken manure and their own growth.
[0041] The blower 3 is equipped with a speed regulator 4 to adjust the output power of the blower 3. By adjusting the speed of the blower 3 through the speed regulator 4, the wind speed entering the heating box 5 can be adjusted, so as to better control the internal environmental conditions of the chicken manure material and further improve the effect of black soldier fly treatment of chicken manure.
[0042] The present invention has the following effects: 1. When the driver 13 rotates clockwise, the stirring component 14 stirs the chicken manure, causing it to tumble in the perforated pretreatment box 18. This increases the overall contact area between the chicken manure and heat, ensuring that the chicken manure is heated evenly, improving the heating treatment effect, and further enhancing the pathogen killing efficiency. When the driver 13 rotates counterclockwise, the transmission mechanism 17 drives the crushing component 15 to rotate counterclockwise, crushing the chicken manure. The crushed chicken manure particles become smaller, and their physical state is improved, which is more conducive to the feeding and digestion of black soldier flies, promoting the growth of black soldier flies.
[0043] 2. The crushing component 15 and the mixing component 14 are connected by the transmission mechanism 17, realizing the linkage of crushing and mixing functions. During the crushing process, the crushing component 15 does not block the holes of the perforated pretreatment box 18, so that the chicken manure can fall smoothly into the feeding box 6 inside the breeding box 1, ensuring the continuity and efficiency of the entire processing process, and completing multiple processing steps without additional operation.
[0044] 3. The design of the crushing and mixing component ensures that the chicken manure is fully mixed and crushed during the pretreatment process. The mixing action increases the contact area between the chicken manure and heat, making the heating more uniform and rapid. The crushing action reduces the size of the chicken manure particles, further improving the contact efficiency between the chicken manure and heat and other treatment factors, thereby shortening the pretreatment time and improving the efficiency of the entire chicken manure treatment process.
