Description

Technical Field

[0001] This utility model relates to a fully automatic separation system for wet materials containing live insects, 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 screening or utilizing the insects' repulsive behavior; insects escape under directional stimulation of light and heat, thus separating the insects from their excrement. Screening is difficult for materials with high moisture content and easily causes the death of live insects. Repulsive separation is more effective and can be performed well even with high material 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. Furthermore, these structures lack mechanisms for controlling material thickness, further contributing to their low insect separation efficiency. Utility Model Content

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-running inlet, and the other end has an insect-running outlet. The larval repellency mechanism, designed to induce larval repulsion, is located within the insect-discharging space.

[0008] The discharge end of the material distribution conveyor belt is connected to the feed end of the wire mesh belt.

[0009] Furthermore, preferably: the wire mesh belt is a diamond-shaped wire mesh belt, and the wire mesh belt has 1-5 layers of wire mesh belt.

[0010] Furthermore, preferably, the wire mesh belt is provided with a mesh belt cleaning mechanism at the discharge end or the feed end;

[0011] Alternatively, the wire mesh belt may be equipped with a mesh belt cleaning mechanism at both the discharge and feed ends.

[0012] Furthermore, preferably, the mesh belt cleaning mechanism is a wire brush or a roller brush for cleaning insects.

[0013] Furthermore, preferably, a chain mesh adjuster is provided on the drive shaft.

[0014] Furthermore, preferably, the larval repulsion mechanism includes at least one of a heating mechanism, a cooling mechanism, and a lighting mechanism.

[0015] Further, 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 second frame and the wire mesh belt, and the side heat insulation plates are movably connected to the heat insulation cover frame.

[0016] Further, preferably: the dispersion and leveling mechanism includes a first dispersion and leveling mechanism, the first dispersion and leveling mechanism includes a roller with stirring teeth, the roller is mounted on the frame, and the roller is mounted together with the motor mechanism;

[0017] Alternatively, the dispersion and leveling mechanism may include a second dispersion and leveling mechanism, which includes a plurality of brush rollers and roller brushes. The brush rollers are interconnected by a transmission mechanism, and the roller brushes extend into the rollers of the brush rollers, with the brush head of the roller brushes being higher than the height of the conveyed material.

[0018] Furthermore, preferably: the dispersion and leveling mechanism is a single, first dispersion and leveling mechanism, located at the first discharge port;

[0019] Alternatively, there may be two dispersing and leveling mechanisms, namely a first dispersing and leveling mechanism and a second dispersing and leveling mechanism. The first dispersing and leveling mechanism is located at the first discharge port, and the second dispersing and leveling mechanism is located above the discharge end of the material distribution conveyor belt.

[0020] Furthermore, preferably: the second dispersing and leveling mechanism further includes a brush cover, the brush cover is installed on the frame, the front of the brush cover is in contact with the hopper and is provided with a discharge hole adapted to the first discharge port, the rear of the brush cover is provided with a second discharge port, and the left and right sides of the brush cover are in contact with the material distribution conveyor belt.

[0021] Furthermore, preferably: the first discharge port or the second discharge port is provided with a discharge adjustment mechanism;

[0022] Alternatively, the first and second discharge ports may be equipped with discharge adjustment mechanisms.

[0023] The beneficial effects of this utility model are:

[0024] This invention uses a dispersing and leveling mechanism to evenly spread wet materials into a thin layer, avoiding material accumulation that could cause live insects to hide and significantly improving the exposure rate of live insects. The seamless connection between the material distribution conveyor belt and the wire mesh belt forms a fully automated process of "spreading → separation → collection", reducing manual intervention and improving processing efficiency. The wire mesh belt intercepts wet materials, while the insect-collecting conveyor belt collects live insects, achieving physical separation of live insects from materials with high separation efficiency.

[0025] 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.

[0026] 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.

[0027] 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 separation efficiency and extend the service life of the wire mesh belt.

Detailed Implementation

[0044] 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.

[0045] Example 1

[0046] like Figure 1-8 As shown, a fully automatic separation system for wet materials containing live insects includes a flat feeding device 1 and a live insect separation device 2.

[0047] The flat feeding device 1 includes a hopper 1-3, a material distribution conveyor belt 1-5, a first frame 1-2, and several distributed flattening mechanisms. The material distribution conveyor belt 1-5 is installed on the first frame 1-2, and the hopper 1-3 is located above one end of the material distribution conveyor belt 1-5. A first discharge port 1-6 is provided at the bottom of the hopper 1-3.

[0048] The feed silos 1-3 are used for temporary storage of materials after the breeding season ends: insect excrement and live insects. Their structure can be designed according to actual needs; in this embodiment, a square pyramidal feed silo 1-3 is used. The distribution conveyor belt 1-5 can be made of a suitable material as needed; generally, a corrosion-resistant conveyor belt is sufficient. Scrapers, baffles 1-9, etc., can be installed on the distribution conveyor belt 1-5 to clean debris from the conveyor belt surface and prevent material spillage.

[0049] The dispersing and leveling mechanism is mainly used to break up and spread the material in bins 1-3, facilitating subsequent insect expulsion operations. A mechanism with a stirring and dispersing function is sufficient; however, care must be taken not to stir and disperse too densely or at too high a speed, which could kill any living organisms in the material. The number of dispersing and leveling mechanisms can be selected according to the actual situation, such as 1, 2, 3, etc.

[0050] This embodiment employs a single dispersing and leveling mechanism, comprising a first dispersing and leveling mechanism. The first dispersing and leveling mechanism includes a roller 1-10 with stirring teeth 1-11, which is mounted on the frame via bearings. The roller 1-10 is also mounted together with a second motor mechanism. The dispersing and leveling mechanism can be positioned on the material distribution conveyor belt 1-5; in this embodiment, it is positioned at the first discharge port 1-6. This not only disperses and levels the material but also accelerates material discharge and prevents discharge blockage.

[0051] The first power mechanism 1-1 can be a separate power mechanism, such as an adjustable speed motor, or it can share the same power mechanism as the material distribution conveyor belt 1-5, and be installed together with the power mechanism of the material distribution conveyor belt 1-5 via sprockets or pulleys. The power mechanism of the material distribution conveyor belt 1-5 is no different from that of an ordinary conveyor belt; a suitable motor can be selected as needed, which will not be described in detail here.

[0052] This embodiment uses a separate power mechanism and an adjustable speed motor. The motors for the material conveyor belts 1-5 are not shown in the figure.

[0053] To adjust the discharge speed, a discharge adjustment mechanism is provided. In this embodiment, the discharge adjustment mechanism includes a first discharge adjustment plate 1-4. The first discharge adjustment plate 1-4 is fixed in the discharge adjustment groove 1-8 by a discharge slider 1-7. The discharge adjustment groove 1-8 is set on the hopper 1-3. The discharge amount is adjusted by adjusting the position of the slider 2-105 in the discharge adjustment groove 1-8.

[0054] The live insect separation device 2 includes a heat insulation cover, a wire mesh belt 2-2, a second frame 2-7, and a larval avoidance mechanism. At least four drive shafts 2-4 are arranged around the frame, and each drive shaft 2-4 is connected to a second power mechanism 2-1. The drive shafts 2-4 are mounted together with the second frame 2-7, and are connected to the wire mesh belt 2-2 via first sprockets 2-12 at both ends. An insect-catching conveyor belt 2-8 is located inside the wire mesh belt 2-2, and an insect-discharging conveyor belt 2-5 is located at the outlet end of the insect-catching conveyor belt 2-8. The heat insulation cover is mounted on the second frame 2-7, and together with the wire mesh belt 2-2 located above the insect-catching conveyor belt 2-8, forms 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 located within the insect-discharging space.

[0055] The purpose of the insulation cover is to form a sealed, insulated space together with the wire mesh belt 2-2 to facilitate insect escape operations. It can be made of ordinary insulation material with one open side.

[0056] The solution adopted in this embodiment is as follows: The insulation cover includes an insulation cover frame, on which a front insulation plate 2-11, a rear insulation plate 2-3, a side insulation plate 2-6, and a top insulation plate 2-9 are provided. The front insulation plate 2-11 has an inlet for insects to escape, and the rear insulation plate 2-3 has an outlet for insects to escape. The side insulation plate 2-6 is in contact with the frame and the wire mesh belt 2-2, and is movably connected to the insulation cover frame. For ease of installation, the front insulation plate 2-11, rear insulation plate 2-3, side insulation plate 2-6, and top insulation plate 2-9 can be a combination of multiple insulation plates. Simultaneously, the side insulation plate 2-6 is movably connected to the insulation cover frame 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.

[0057] The wire mesh belt 2-2 primarily provides an escape route for live insects. Generally, the mesh size of the wire mesh belt 2-2 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 2-2 is used, and reinforcing ribs are provided on the wire mesh belt 2-2. To improve the strength and separation effect of the wire mesh belt 2-2, a multi-layer structure of the wire mesh belt 2-2 can be used, generally 1-5 layers are sufficient. The number of layers of the wire mesh belt 2-2 can be adjusted according to the length of the equipment and the operating speed. This embodiment uses 2 layers of wire mesh.

[0058] At least four drive shafts 2-4 are arranged around the second frame 2-7. In this embodiment, four drive shafts 2-4 are used, respectively arranged around the perimeter of the frame. The distance between the two upper drive shafts 2-4 is greater than the distance between the two lower drive shafts 2-4. This structure facilitates the collection of insect sand after the insects have escaped. One of the drive shafts 2-4 is connected to a first power mechanism, which is generally an adjustable speed motor.

[0059] The drive shaft 2-4 is installed together with the second frame 2-7, and the drive shaft 2-4 is installed together with the wire mesh belt 2-2 via sprockets at both ends thereon.

[0060] To adjust the tension of the wire mesh belt 2-2, a chain mesh adjuster 2-10 is provided on the drive shaft 2-4. The structure of the chain mesh adjuster 2-10 can be designed according to actual conditions, as long as it can adjust the tension of the wire mesh belt 2-2. In this embodiment, the chain mesh adjuster 2-10 includes an adjuster body 2-102 with a guide groove 2-103, an adjusting slider 2-105, and an adjusting screw 2-104. One side of the guide groove 2-103 is provided with a mesh belt adjusting groove 2-107. The adjusting slider 2-105 is disposed in the guide groove 2-103 and has a mounting hole 2-106. The adjusting screw 2-104 is mounted to the adjusting slider 2-105 through a threaded hole 2-101 on the guide groove 2-103. The drive shaft 2-4 passes through the mesh belt adjusting groove 2-107 and is fixed in the mounting hole.

[0061] The larval repulsion mechanism mainly refers to the mechanism that induces larval repulsion behavior above and below the wire mesh belt 2-2, including at least one of a heating mechanism 2-13, a cooling mechanism, and a lighting mechanism 2-14. Different mechanisms can be selected based on the actual situation. For example, in hot summer weather, a heating mechanism 2-13 can be installed above the wire mesh belt 2-2 to increase the temperature difference between the upper and lower parts of the wire mesh belt 2-2, causing the larvae to move downwards and achieve separation. Alternatively, a cooling mechanism can be installed below the wire mesh belt 2-2, which can also increase the temperature difference between the upper and lower parts of the wire mesh belt 2-2, causing the larvae to move downwards and achieve separation.

[0062] For example, in cold winter weather, a heating mechanism 2-13 can be installed below the wire mesh belt 2-2 to increase the temperature difference between the upper and lower parts of the wire mesh belt 2-2, causing the larvae to move downwards and achieve separation. Alternatively, a cooling mechanism can be installed above the wire mesh belt 2-2, which can also increase the temperature difference between the upper and lower parts of the wire mesh belt 2-2, causing the larvae to move downwards and achieve separation.

[0063] 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.

[0064] The direction in which the larvae escape can also be selected; the larvae can be chosen to escape upwards to separate them.

[0065] The solution adopted in this embodiment is as follows:

[0066] The larval repulsion mechanism includes a heating mechanism 2-13 and a lighting mechanism 2-14. The heating mechanism 2-13 is located at the feed end of the wire mesh belt 2-2. By combining the heating mechanism 2-13 and the lighting mechanism 2-14, the larvae can be induced to exhibit repulsive behavior through light and heat, thereby achieving larval separation. The heating mechanism 2-13 is generally an electric heating rod, but other heating methods such as hot air can also be used.

[0067] The insect-collecting conveyor belt 2-8 and the insect-exiting conveyor belt 2-5 can be made of corrosion-resistant conveyor belts. Scrapers, baffles 1-9 and other mechanisms can be installed on the conveyor belts to clean them and prevent larvae from escaping.

[0068] Insect sand collection mechanisms can be set at both ends of the wire mesh belt 2-2 for collecting the separated insect sand. Equipment such as collection boxes and conveyor belts can be used.

[0069] During operation, some sand may adhere to the wire mesh belt 2-2, and even enter the mesh openings, causing a decrease in the separation efficiency of the wire mesh belt 2-2. To improve the separation efficiency and service life of the wire mesh belt 2-2, this embodiment includes a belt cleaning mechanism. The belt cleaning mechanism can use a wire brush 2-16 or a roller brush 2-15. One belt cleaning mechanism can be selected and installed at the discharge end or feed end of the wire mesh belt 2-2, or at other locations. Alternatively, two belt cleaning mechanisms can be selected and installed at both the discharge end and feed end of the wire mesh belt 2-2.

[0070] The mesh belt cleaning mechanism can be either two identical mechanisms or two different mechanisms. In this embodiment, two different mesh belt cleaning mechanisms are selected: a wire brush 2-16 and a roller brush 2-15. One is more rigid, and the other is more flexible. The combination of the two can better clean the wire mesh belt 2-2. The wire brush 2-16 is mounted on the frame via a fixing plate 1-20.

[0071] The material distribution conveyor belt 1-5 of the flat feeding device is set above the wire mesh belt 2-2 of the live insect separation device, so that the broken material falls onto the wire mesh belt 2-2. Alternatively, the material distribution conveyor belt 1-5 and the wire mesh belt 2-2 can be connected together by a connecting plate to realize the material transfer and conveying operation between the flat feeding device and the live insect separation device.

[0072] The operation process of this embodiment:

[0073] Start the heating mechanism 2-13 and the lighting mechanism 2-14 to bring the temperature and light inside the heat insulation hood to the set values, and then turn on the wire mesh belt 2-2, the insect receiving conveyor belt 2-8 and the insect exit conveyor belt 2-5.

[0074] Material containing live insects is placed into hopper 1-3, and then the power mechanism of the distribution conveyor belt 1-5 is turned on. The distribution conveyor belt 1-5 moves, simultaneously driving the first dispersing and leveling mechanism to rotate. While the material is being conveyed, it is dispersed and leveled. The thickness of the dispersed and leveled material is generally 0.5-5cm. The dispersed and leveled material falls onto the wire mesh belt 2-2, which carries the material into the heat insulation hood. Under the influence of light and heat, the larvae move downwards from the wire mesh belt 2-2 and fall onto the insect-collecting conveyor belt 2-8. The insect-collecting conveyor belt 2-8 collects the fallen larvae and conveys them to the insect-exiting conveyor belt 2-5. The insect-exiting conveyor belt 2-5 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 2-2, completing the larval separation and collection operation.

[0075] The insect-repelling wire brush 2-16 and the insect-repelling roller brush 2-15 clean out the insects and sand adhering to the wire mesh belt 2-2 and inside the mesh holes, which can effectively improve the separation efficiency.

[0076] This invention features a simple structure and convenient operation. The separation of larvae can be achieved through a flat feeding device and a live insect separation device, resulting in a high degree of automation. The structure of this embodiment is suitable for materials with high moisture and viscosity that are difficult to disperse and flatten.

[0077] Example 2

[0078] like Figure 9-13 As shown, it is basically the same as Example 1, except that:

[0079] The spreading and leveling mechanism of the flat feeding device includes a second spreading and leveling mechanism, which includes several brush rollers 1-18 and roller brushes 1-17. The brush rollers 1-18 are connected to each other through a transmission mechanism. The roller brushes 1-17 extend into the roller brushes of the brush rollers 1-18. The brush head of the roller brushes 1-17 is higher than the height of the conveyed material, generally between 5-15mm.

[0080] The distributed leveling mechanism can be used alone or in combination with the first distributed leveling mechanism.

[0081] This embodiment uses a combination of two dispersing and leveling mechanisms: a first dispersing and leveling mechanism and a second dispersing and leveling mechanism. The first dispersing and leveling mechanism is located at the first discharge port 1-6, and the second dispersing and leveling mechanism is located above the discharge end of the material distribution conveyor belt 1-5.

[0082] The number of brush rollers 1-18 and roller brushes 1-17 can be set according to the material moisture and the flatness of the spread. Brush rollers 1-18 are generally made of flexible plastic to avoid affecting live insects; roller brushes 1-17 are generally made of hard brushes, such as wire brushes, and their main function is to remove material from brush rollers 1-18.

[0083] The second dispersing and leveling mechanism also includes a brush cover 1-12, which is mounted on the frame. The front of the brush cover 1-12 is in contact with the hopper 1-3 and is provided with a discharge hole adapted to the first discharge port 1-6. The rear of the brush cover 1-12 is provided with a second discharge port 1-13, and the left and right sides of the brush cover 1-12 are in contact with the material distribution conveyor belt 1-5.

[0084] Setting up brush covers 1-12 can effectively solve problems such as material splashing and live insects escaping, thereby improving work efficiency and quality.

[0085] The power mechanism for a single roller brush 1-17 can be a separate power mechanism, or multiple roller brushes 1-17 can share a single power mechanism. One end of the brush roller 1-18 is equipped with a second sprocket 1-15 or a pulley. The roller shaft 1-10 or the drive shaft 2-4 is connected to the brush roller 1-18 via a chain 1-16 or a belt. In this embodiment, a combination of chain 1-16 and sprocket is used. Chain 1-16 and the first sprocket 2-12 are housed within the chain box 1-14.

[0086] The power mechanism in this embodiment is the same as that of the first dispersing and leveling mechanism, and is installed together with the rollers 1-10 via sprockets or pulleys. The power mechanism of the material distribution conveyor belts 1-5 is no different from that of ordinary conveyor belts; a suitable motor can be selected as needed, and will not be described in detail.

[0087] Alternatively, the same power mechanism as the material distribution conveyor belts 1-5 can be used, and they can be installed together using a combination of sprockets and chains.

[0088] Therefore, a discharge adjustment mechanism is set at the discharge port to effectively control the discharge speed. In this embodiment, a discharge adjustment mechanism is set at the first discharge port 1-6, or a discharge adjustment mechanism can be set at the second discharge port 1-13.

[0089] Alternatively, discharge adjustment mechanisms can be installed at both the first discharge port 1-6 and the second discharge port 1-13.

[0090] The discharge adjustment mechanism can be set according to actual conditions. In this embodiment, the discharge adjustment mechanism includes a second discharge adjustment plate 1-22, which is installed together with a fixed plate 1-20 via a threaded connecting rod 1-21. The fixed plate 1-20 is fixed together with the hopper 1-3. The threaded connecting rod 1-21 is installed together with the fixed plate 1-20, and an adjustment handle 1-19 is provided at the top of the threaded connecting rod 1-21. This mechanism is simple, easy to operate, and low in cost. An automatic discharge adjustment mechanism can also be used.

[0091] The live insect separation device no longer includes the worm-running wire brush 2-16 and the worm-running roller brush 2-15.

[0092] The operation process of this embodiment:

[0093] The materials in silos 1-3 are thoroughly dispersed by the first and second dispersion and leveling mechanisms before entering the live insect separation device for separation. This embodiment is suitable for materials containing live insects that have relatively low moisture and viscosity and are easily dispersed.

[0094] 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.
