Description

Technical Field

[0001] The utility model relates to the technical field of insect breeding equipment and the field of agricultural engineering, in particular to a stacked seesaw type deep trough aeration type three-dimensional insect breeding equipment. Background Art

[0002] The black soldier fly, also known as the bright-spotted flat-horned soldier fly, is a saprophytic insect of the family Smilocybinidae in the order Diptera. Its larvae can consume a wide variety of decaying organic matter, eating a large amount and converting organic waste into their own components in a short period of time, increasing their weight by a thousand times. Black soldier fly farming products also have high economic value. Fully grown larvae can be used as animal feed or to produce biodiesel; the residual material left after the black soldier flies process organic waste can be used as organic fertilizer. Using black soldier fly larvae to convert organic waste into animal protein feed has become a hotly debated emerging process. In recent years, black soldier flies have been farmed on a large scale in Shanghai, Jiangsu, Guangxi, and other places in my country, and are widely used to treat waste such as chicken manure and food waste.

[0003] Currently, the bioconversion of organic waste using black soldier flies is primarily achieved through extensive ground farming or stacked box farming. Ground farming requires a large floor space and relies on manual feed sorting, which increases labor costs and inefficiencies. While stacked box farming reduces floor space through stacked culture equipment, it still requires additional external auxiliary equipment, increasing operating costs. Black soldier fly farming generates significant amounts of ammonia and heat. Because most existing farming methods utilize natural ventilation, these gases and heat cannot be expelled promptly, leading to delayed development and even death of the black soldier flies. Overall, existing farming methods have high labor costs, hindering economic efficiency and precise temperature control of feed during the farming process.

[0004] Automated breeding mode is a new trend in the current breeding field. Fully automatic breeding can not only reduce labor costs, but also improve conversion efficiency. However, most of the existing automated breeding uses discharging robots for discharging, which has a high degree of automation, but is also complex and difficult to maintain. The applicant's prior application for a utility model patent with the publication number CN 220458341 U designed a non-powered stacked seesaw-type insect breeding equipment, which adopts a structure similar to the "seesaw" principle, making manual or robotic arm-assisted discharging more time-saving and labor-saving. At the same time, the multi-layer breeding box supports the center of gravity of the main column through bearings and seesaw support rods, reducing the stress requirements of the frame structure supporting the breeding box in the equipment. By reducing the material or specification requirements, the equipment cost can be greatly reduced. Its disadvantage is that it cannot discharge the harmful gases and heat inside the breeding process in time, which can easily lead to delayed development or even death of black soldier flies. For example, Chinese utility model publication No. CN 209950163 U designs a fully automatic three-dimensional breeding device for black soldier flies. This stacking tray breeding equipment achieves automated breeding and boasts a relatively high level of automation maturity. However, the equipment is complex in structure, has a high failure rate during operation, and suffers from high equipment investment, high operating costs, and a low input-output ratio. Publication No. CN 210157873 U designs a semi-automatic breeding rack for black soldier flies. By stacking breeding frames in two sections, the overall structure and floor space are significantly reduced, increasing the breeding yield and facilitating unloading. However, manually operated latches are required for tipping and resetting, which is time-consuming and labor-intensive. Furthermore, unloading from both sides prevents the use of a shared discharge conveyor, resulting in low space utilization. Publication No. CN 217657778 U designs a simplified, lightweight, stacked insect breeding equipment. This design utilizes two rows of multi-layered breeding boxes, with brake motors driving each row of boxes to unload simultaneously onto a conveyor at the bottom of the central axis. This significantly reduces unloading speed and conserves breeding space. Publication No. CN 214339501 U designed an aerated culture box. By providing aeration through holes in the aeration base, it addressed the issue of heat dissipation during the culture process. However, the number of black soldier flies cultured was limited, and the equipment had a high failure rate.

[0005] In general, existing automated aquaculture equipment includes containerized, warehouse-based, assembly-line, and tunnel-based types. However, these equipment suffer from common drawbacks, such as complex structure, high failure rates, high equipment investment, high operating costs, and low yields, severely hindering the industrialization of organic waste-based black soldier fly conversion technology. On the one hand, the operational efficiency and stability of automated aquaculture equipment need to be improved. On the other hand, semi-automated or mechanized aquaculture equipment, due to the presence of moving parts, has a high failure rate due to long-term exposure to high humidity and high ammonia conditions. Furthermore, due to the high power requirements and material requirements of the aquaculture frame based on the equipment design and principles, it is difficult to meet the market demand for cost-saving and energy-saving measures. Third, existing insect aquaculture equipment often lacks precise control over oxygen supply, ventilation, and cooling, failing to meet the growth and development needs of insects, thus affecting their growth and production. Therefore, the urgent need to design and develop a stacked seesaw-type deep-tank aerated three-dimensional insect aquaculture system has become a technical bottleneck that needs to be addressed in insect aquaculture. Utility Model Content

[0006] In order to solve the problems of the prior art, the utility model provides a stacked seesaw-type deep-trough aeration-type three-dimensional insect breeding equipment, which solves the problem that the existing breeding equipment cannot discharge the harmful gases and heat inside the breeding process in time, resulting in the slow development or even death of black soldier flies. Aeration is performed through the aeration device, so that the black soldier fly larvae in the breeding box can mobilize enough oxygen for production and maintain a stable growth state, and can discharge the ammonia, water vapor and heat generated in the breeding process, and can prevent the breeding box from accumulating too much ammonia and excess heat, thereby affecting the growth of the black soldier fly larvae.

[0007] The utility model provides a stacked seesaw-type deep-trough aeration-type three-dimensional insect breeding equipment, which includes a breeding frame and a bilaterally symmetrical multi-layer breeding box installed on the breeding frame. A hollow aeration interlayer is provided at the bottom of the breeding box. The aeration interlayer is a closed air chamber composed of an upper porous plate and a lower plate. The surface of the upper porous plate is covered with a breathable membrane and a nylon mesh in sequence. The closed air chamber is connected to an aeration device. The aeration amount can be adjusted by the frequency and aeration duration of the aeration device.

[0008] As a further improvement, the aeration interlayer is a drawer-like aeration splint structure, and air inlets are provided at the corners of the aeration interlayer.

[0009] As a further improvement, a slot is provided at the bottom of the breeding box, the aeration interlayer is inserted into the slot, and a pull handle for controlling the insertion and extraction of the aeration interlayer is provided at one end of the aeration interlayer.

[0010] As a further improvement, the slot is a U-shaped slot that is completely sealed with the breeding box body, and a U-shaped sealing ring is installed inside the slot.

[0011] As a further improvement, a compression device connected by a screw is provided at the bottom of the aeration interlayer, and a crank is provided at one end of the screw. The crank is driven by the positive and negative rotation of the crank to control the up and down movement of the aeration interlayer, thereby achieving compression and sealing with the breeding box body.

[0012] The beneficial effects of the utility model are:

[0013] 1. This equipment features an aeration chamber below the breeding box. The aeration device provides aeration, ensuring the black soldier fly larvae in the box receive sufficient oxygen for reproduction and stable growth. The aeration device adjusts the aeration intensity according to the early and late stages of the larvae's growth, preventing over-aeration. Furthermore, the aeration module exhausts ammonia, water vapor, and heat generated during the breeding process, preventing the accumulation of excessive ammonia and heat in the breeding box, which could affect the growth of the black soldier fly larvae.

[0014] 2. This equipment adopts a structure similar to the "seesaw" principle, which makes manual or robotic arm-assisted discharging more time-saving and labor-saving. At the same time, the center of gravity of the multi-layer breeding boxes is supported by the main column through bearings and seesaw support rods, which reduces the stress requirements of the frame structure supporting the breeding boxes in the equipment. By reducing material or specification requirements, the equipment cost can be greatly reduced.

[0015] 3. Except for bearings, this equipment has no power equipment and other components with high failure rate risk, which improves the stability of the equipment.

[0016] 4. Each layer of the stacked breeding rack of this equipment is equipped with two breeding box racks on the left and right. The breeding box racks on each layer are set at the same distance, which realizes the lightweight and simplified design of the feeding equipment, while increasing the breeding area and improving breeding efficiency. When discharging, the breeding box racks on the same side can discharge at the same time; compared with the existing stacked breeding equipment's two-side discharge mode, it improves the utilization rate of breeding land and does not affect the feeding vehicle's operation channel.
