Description

Technical Field

[0001] This utility model relates to a fully automatic live insect separation device for wet materials, belonging to the category of live insect separation equipment. Background Technology

[0002] Insect farming can transform agricultural waste (such as kitchen waste and livestock manure) into high-value products. For example, black soldier fly larvae can consume 800 kg of kitchen waste in 20 days, producing 200-300 kg of insect bodies and 300 kg of high-quality organic fertilizer. Yellow mealworms can convert straw into insect protein and organic fertilizer, achieving resource recycling. Simultaneously, the decomposition of organic waste by insects can block the spread of pathogens, hormones, and antibiotics. For example, black soldier flies can degrade viruses in the carcasses of diseased and dead livestock, reducing the risk of environmental pollution. Furthermore, insect farming does not require the use of chemical pesticides, conforming to the principles of organic agriculture. Separation of live insects is crucial in insect farming. Existing methods generally involve sieving or utilizing the insects' repulsive behavior; insects escape under directional stimulation of light and heat, thus separating the insects from their excrement. Sieving is difficult for materials with high moisture content and easily causes the death of live insects. Repulsive separation is more effective and can separate insects even when the material has high moisture content. For example, patents with application numbers 202320714109.6, 202321680996.6, and 202321493119.8 employ combinations of conveyor belts, releasable supports, insect drop platforms, insect drop guides, and material conveying carriers to achieve rapid separation of live insects. However, these structures require multiple releasable supports, insect drop platforms, insect drop guides, and material conveying carriers, resulting in large equipment footprints, low automation, and low separation efficiency. Utility Model Content

[0003] This invention provides a fully automatic live insect separation device for wet materials, which solves the problems of existing insect repulsion separation equipment having a large footprint, low automation level, and low separation efficiency.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0005] A fully automatic live insect separation device for wet materials includes a heat-insulating cover, a wire mesh belt, a frame, and a larval repellency mechanism. At least four drive shafts are arranged around the frame, and each drive shaft is connected to a power mechanism. The drive shafts are mounted together with the frame and connected to the wire mesh belt via sprockets at both ends. An insect-catching conveyor belt is located inside the wire mesh belt, and an insect-discharging conveyor belt is located at its outlet end. The heat-insulating cover is mounted on the frame, and together with the wire mesh belt located above the insect-catching conveyor belt, forms an insect-discharging space. One end of the heat-insulating cover has an insect-inlet, and the other end has an insect-outlet. The larval repellency mechanism, which induces larval repellency behavior, is located within the insect-discharging space.

[0006] Furthermore, preferably, the wire mesh belt is a diamond-shaped wire mesh belt, and the wire mesh belt is provided with reinforcing ribs.

[0007] Furthermore, preferably, the wire mesh belt is a 1-5 layer wire mesh belt.

[0008] Furthermore, preferably: the wire mesh belt is equipped with a mesh belt cleaning mechanism at the discharge end or the feed end;

[0009] Alternatively, the wire mesh belt may be equipped with a mesh belt cleaning mechanism at both the discharge and feed ends.

[0010] Furthermore, preferably, the mesh belt cleaning mechanism is a wire brush or roller brush for insects to escape.

[0011] Furthermore, preferably, a chain mesh adjuster is provided on the drive shaft.

[0012] Furthermore, preferably: the chain mesh regulator includes an regulator body with a guide groove, an adjusting slider, and an adjusting screw. One side of the guide groove has an adjusting groove. The adjusting slider is disposed in the guide groove and has a mounting hole. The adjusting screw is mounted to the adjusting slider through a threaded hole in the guide groove. The drive shaft passes through the adjusting groove and is fixed in the mounting hole.

[0013] Furthermore, preferably, the larval repulsion mechanism includes at least one of a heating mechanism, a cooling mechanism, and a lighting mechanism.

[0014] Furthermore, preferably: the larval repulsion mechanism includes a heating mechanism and a lighting mechanism, wherein the heating mechanism is located at the larval feeding end.

[0015] Furthermore, preferably: the heat insulation cover includes a heat insulation cover frame, on which a front heat insulation plate, a rear heat insulation plate, a side heat insulation plate and a top heat insulation plate are provided; the front heat insulation plate is provided with an insect inlet, the rear heat insulation plate is provided with an insect outlet, the side heat insulation plates are in contact with the frame and the wire mesh belt, and the side heat insulation plates are movably connected to the heat insulation cover frame.

[0016] The beneficial effects of this utility model are:

[0017] This invention utilizes a wire mesh belt driven by a transmission shaft to create a cyclical motion. Wet material moves along the belt surface, and as it falls through the mesh, the high moisture content creates adhesive resistance, causing live insects to actively detach from the material due to their avoidance response. The insects then fall through the mesh onto the insect-collecting conveyor belt below, achieving dynamic separation between the insects and the wet material. The stepped design of the insect-collecting and insect-exiting conveyors ensures rapid insect discharge and a high degree of automation.

[0018] In this invention, the sealed space for larvae to escape formed by the heat insulation cover and the mesh belt can stabilize the temperature and humidity. Combined with the repulsion mechanism (such as a specific light source, temperature rise or gas release), it can directionally stimulate the larvae, enhance their escape behavior, and promote their faster escape from the sticky substrate, thereby improving the escape efficiency and thus improving the analysis efficiency.

[0019] The high porosity and rigid structure of the wire mesh belt of this invention can reduce wet material blockage. The continuous operation of the drive shaft causes the mesh belt to vibrate, further peeling off the attached material, which can effectively improve the analysis efficiency and extend the service life of the wire mesh belt.

Detailed Implementation

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Example 1

[0031] like Figure 1-5 As shown, a fully automatic wet material live insect separation device includes a heat insulation cover, a wire mesh belt 2, a frame 7, and a larval avoidance mechanism. At least four drive shafts 4 are arranged around the frame 7, and each drive shaft 4 is connected to a power mechanism 1. The drive shafts 4 are installed together with the frame 7, and are connected to the wire mesh belt 2 via sprockets 12 at both ends. An insect-catching conveyor belt 8 is installed inside the wire mesh belt 2, and an insect-discharging conveyor belt 5 is installed at the discharge end of the insect-catching conveyor belt 8. The heat insulation cover is mounted on the frame 7, and the heat insulation cover and the wire mesh belt 2 located above the insect-catching conveyor belt 8 form an insect-discharging space. One end of the heat insulation cover has an insect-running inlet, and the other end has an insect-running outlet. The larval avoidance mechanism, which induces larval avoidance behavior, is installed within the insect-discharging space.

[0032] The purpose of the insulation cover is to form a sealed, insulated space together with the wire mesh belt 2 to facilitate insect escape operations. It can be made of ordinary insulation material with one open side.

[0033] The solution adopted in this embodiment is as follows: The insulation cover includes an insulation cover frame 7, on which a front insulation plate 11, a rear insulation plate 3, side insulation plates 6, and a top insulation plate 9 are provided. The front insulation plate 11 is provided with an insect inlet, and the rear insulation plate 3 is provided with an insect outlet. The side insulation plates 6 are in contact with the frame 7 and the wire mesh belt 2, and are movably connected to the insulation cover frame 7. For ease of installation, the front insulation plate 11, rear insulation plate 3, side insulation plate 6, and top insulation plate 9 can be a combination of multiple insulation plates. Simultaneously, the side insulation plates 6 are movably connected to the insulation cover frame 7 using hinges, pins, or other mechanisms, facilitating observation of the internal operation process and timely removal of impurities left behind during insect escape. Alternatively, observation holes or other mechanisms can be provided on the insulation cover.

[0034] The wire mesh belt 2 primarily provides an escape route for live insects. Generally, the mesh size of the wire mesh belt 2 should match the largest diameter of the live insect to be separated, or be 0.1-5 mm larger. In this embodiment, a diamond-shaped wire mesh belt 2 is used, and reinforcing ribs are provided on the wire mesh belt 2. To improve the strength and separation effect of the wire mesh belt 2, a multi-layer structure of the wire mesh belt 2 can be used, generally 1-5 layers are sufficient. The number of layers of the wire mesh belt 2 can be adjusted according to the length of the equipment and the operating speed. This embodiment uses 2 layers of wire mesh.

[0035] At least four drive shafts 4 are arranged around the frame 7. In this embodiment, four drive shafts 4 are used, respectively arranged around the frame 7. The distance between the two upper drive shafts 4 is greater than the distance between the two lower drive shafts 4. This structure facilitates the collection of insect sand after the insects have escaped. One of the drive shafts 4 is connected to a power mechanism 1, which is generally an adjustable speed motor.

[0036] The drive shaft 4 is installed together with the frame 7, and the drive shaft 4 is installed together with the wire mesh belt 2 via sprockets 12 at both ends thereon.

[0037] To adjust the tension of the wire mesh belt 2, a chain mesh adjuster 10 is provided on the drive shaft 4. The structure of the chain mesh adjuster 10 can be designed according to the actual situation, as long as it can adjust the tension of the wire mesh belt 2. In this embodiment, the chain mesh adjuster 10 includes an adjuster body 102 with a guide groove 103, an adjusting slider 105, and an adjusting screw 104. One side of the guide groove 103 is provided with an adjusting groove 107. The adjusting slider 105 is disposed in the guide groove 103 and has a mounting hole 106. The adjusting screw 104 is mounted to the adjusting slider 105 through a threaded hole 101 on the guide groove 103. The drive shaft 4 passes through the adjusting groove 107 and is fixed in the mounting hole 106.

[0038] The larval repulsion mechanism is mainly a mechanism that creates repulsive behavior in the upper and lower parts of the wire mesh belt 2, including at least one of a heating mechanism 13, a cooling mechanism, and a lighting mechanism 14. Different mechanisms can be selected depending on the actual situation. For example, in hot summer weather, a heating mechanism 13 can be installed above the wire mesh belt 2 to increase the temperature difference between the upper and lower parts of the wire mesh belt 2, causing the larvae to move downwards and achieve separation. Alternatively, a cooling mechanism can be installed below the wire mesh belt 2, which can also increase the temperature difference between the upper and lower parts of the wire mesh belt 2, causing the larvae to move downwards and achieve separation.

[0039] For example, in cold winter weather, a heating mechanism 13 can be set below the wire mesh belt 2 to increase the temperature difference between the upper and lower parts of the wire mesh belt 2, causing the larvae to move downwards and achieve separation. Alternatively, a cooling mechanism can be set above the wire mesh belt 2, which can also increase the temperature difference between the upper and lower parts of the wire mesh belt 2, causing the larvae to move downwards and achieve separation.

[0040] Other methods can also be used, such as light and ultrasound. Generally, a combination of attraction and avoidance mechanisms is more effective than a single mechanism for separation.

[0041] The direction in which the larvae escape can also be selected; the larvae can be chosen to escape upwards to separate them.

[0042] The solution adopted in this embodiment is as follows:

[0043] The larval repulsion mechanism includes a heating mechanism 13 and a lighting mechanism 14. The heating mechanism 13 is located at the feed end of the wire mesh belt 2. By combining the heating mechanism 13 and the lighting mechanism 14, the larvae can be induced to exhibit repulsive behavior through light and heat, thereby achieving larval separation. The heating mechanism 13 can generally be an electric heating rod, but hot air or other heating methods can also be used.

[0044] The insect-collecting conveyor belt 8 and the insect-exiting conveyor belt 5 can be made of corrosion-resistant conveyor belts. Scrapers, baffles and other mechanisms can be installed on the conveyor belts to clean them and prevent the larvae from escaping.

[0045] Insect and sand collection mechanisms can be set at both ends of the wire mesh belt 2 for collecting the separated insects and sand. Equipment such as collection boxes and conveyor belts can be used.

[0046] The operation process of this embodiment:

[0047] Start the heating mechanism 13 and the lighting mechanism 14 to bring the temperature and light inside the insulation hood to the set values. Then, turn on the wire mesh belt 2, the insect-collecting conveyor belt 8, and the insect-exiting conveyor belt 5. Put material containing live larvae onto the wire mesh belt 2. The material thickness is generally 0.5-5cm. The wire mesh belt 2 carries the material into the insulation hood. Under the action of light and heat, the larvae move downwards from the wire mesh belt 2 and fall onto the insect-collecting conveyor belt 8. The insect-collecting conveyor belt 8 collects the fallen larvae and transports them to the insect-exiting conveyor belt 5. The insect-exiting conveyor belt 5 transports the separated larvae out of the separation equipment and collects them. The insect sand after the larvae are separated falls into the insect sand collection mechanism at both ends of the wire mesh belt, completing the larvae separation and collection operation.

[0048] This invention has a simple structure and is easy to operate. The separation of larvae can be completed by combining a wire mesh belt, an insect-receiving conveyor belt 8, and an insect-exiting conveyor belt 5, resulting in a high degree of automation.

[0049] Example 2

[0050] like Figure 6 and 7 As shown, this embodiment is basically the same as Example 1, except that some insects and sand may adhere to the wire mesh belt during operation, and may even enter the mesh openings, causing a decrease in the separation efficiency of the wire mesh belt. To improve the separation efficiency and service life of the wire mesh belt, this embodiment includes a wire mesh belt cleaning mechanism. This cleaning mechanism can use an insect-repelling wire brush 16 or an insect-repelling roller brush. One wire mesh belt cleaning mechanism can be selected and installed at the discharge end, feed end, or other location of the wire mesh belt. Alternatively, two wire mesh belt cleaning mechanisms can be selected and installed at the discharge end and feed end of the wire mesh belt.

[0051] The mesh belt cleaning mechanism can consist of two identical mechanisms or two different mechanisms. In this embodiment, two different mesh belt cleaning mechanisms are selected: a wire brush 16 and a roller brush. One is more rigid, and the other is more flexible. The combination of the two can better clean the wire mesh belt. The wire brush 16 is mounted on the frame 7 via a fixing plate.

[0052] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
