Description

Technical Field

[0001] This application relates to the field of insect farming technology, and more specifically, to an insect excrement separation system. Background Technology

[0002] Utilizing black soldier fly larvae or fly maggots for the treatment of organic solid waste can not only solve the environmental pollution problem caused by organic solid waste, but also produce insect protein, organic fertilizer, and reduce greenhouse gas emissions, which is of great significance to the development of circular agriculture. Currently, black soldier fly and fly maggot breeding technology is developing rapidly, moving from traditional ground-based rearing to mechanized and automated breeding techniques. However, progress in separating insect excrement from the insects after rearing is limited, becoming one of the limiting factors restricting the development of insect-based organic solid waste treatment technology.

[0003] There are currently two screening methods. One is to use mechanical screens, mainly flat vibrating screens, drum screens, and circular oscillating screens. These methods all use screens to separate insects and insect excrement. This method works well when the material has a low moisture content, but when the material has high moisture and viscosity, it is very easy to clog the screen mesh. The second method utilizes the light- and heat-avoiding characteristics of insects. Under the directional stimulation of light and heat, insects escape downwards from the conveyor belt carrying the insect material, thereby achieving the separation of insects and insect excrement. The drawback of this method is that insects have the instinct to avoid falling. Therefore, in actual operation, when the insect material is carried on the conveyor belt, the insects will try to stay on the conveyor belt by their own movement to avoid falling. That is, most insects will protect themselves from falling through the mesh of the conveyor belt. Only a few insects fall through the mesh of the conveyor belt, which results in poor separation of insects and insect excrement. Summary of the Invention

[0004] The main objective of this invention is to provide an insect excrement separation system, which aims to solve the technical problems of incomplete insect excrement separation, high impurity content, and low efficiency in the existing insect breeding process.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is: an insect excrement separation system, comprising:

[0006] Frame;

[0007] The material conveying carrier set on the frame is capable of reciprocating or cyclical movement to convey materials, and the material conveying carrier has multiple insect drop holes formed on the material conveying carrier.

[0008] A releasable support member is provided, which can be attached to the lower part of the material conveying carrier in a supported state. In the supported state, the releasable support member and the falling mesh form a temporary insect-containing space. Insects contained in the temporary insect-containing space can be supported on the releasable support member. The releasable support member can move away from the material conveying carrier to a released state. In the released state, the releasable support member releases its support for the insects contained in the temporary insect-containing space.

[0009] Furthermore, the insect excrement separation system includes a guide support installed on the frame for supporting the releasable support member. When the releasable support member is supported on the guide support member, it is in the supported state, and when the releasable support member is removed from the guide support member, it is in the released state.

[0010] Furthermore, the guide support extends along the conveying direction of the material conveying carrier, and the guide support includes at least one of a guide rod, a guide plate, a guide block, and a guide wheel.

[0011] Furthermore, the plurality of the guide supports are arranged at intervals along the conveying direction of the material conveying carrier.

[0012] Furthermore, the insect excrement separation system includes a first circulating motion traction structure installed on the frame, the releasable support is installed on the first circulating motion traction structure, and the material conveying carrier is fixed on the first circulating motion traction structure; or, the insect excrement separation system includes a second circulating motion traction structure installed on the frame, and the material conveying carrier is installed on the second circulating motion traction structure.

[0013] Furthermore, the releasable support is a support plate hinged to the first cyclic motion traction structure. In the supported state, the surface of the support plate is against the material conveying carrier. When the support plate moves away from the guide support as the first cyclic motion traction structure moves, the support plate is in an upright state under its own gravity.

[0014] Furthermore, the guide support includes an arc-shaped end structure, and after the support plate moves away from the guide support with the first cyclic motion traction structure, it continues to move and can be supported again on the guide support along the arc-shaped end structure to be in a supported state.

[0015] Furthermore, the first cyclic motion traction structure includes a chain drive assembly, a chain connected to the chain drive assembly, and a mounting component disposed on one side of the chain, wherein the releasable support is mounted on the mounting component.

[0016] Furthermore, the insect excrement separation system includes an electrical control mechanism installed on the frame, the electrical control mechanism being tractively connected to the releasable support member to control the releasable support member to switch between the supported state and the released state.

[0017] Furthermore, the insect excrement separation system also includes:

[0018] The insect drop platform is located at least below the releasable support in its released state;

[0019] An insect repellent device is installed above the material conveying carrier.

[0020] The beneficial effects of the insect excrement separation system provided in this application are as follows:

[0021] Because insects, when on a material conveyor with insect drop holes, will normally try to stay on the conveyor through their own movement to avoid falling, rather than burrowing into the drop holes and falling out, the insect excrement separation system provided by this invention is designed with a releasable support. This releasable support can be placed against the bottom of the material conveyor to provide support. The releasable support and the drop holes form a temporary insect-accommodating space. In this way, for the drop holes on the material conveyor aligned vertically with the releasable support, and for the holes that cannot be simply understood as vertically continuous, the releasable support "supports" these holes, creating a temporary insect-accommodating space. The presence of this device prevents insects from falling through the insect drop mesh. Instead, insects attempt to escape by falling through the mesh. A large number of insects enter the drop mesh, forming a temporary insect-containing space and supporting themselves on the releasable support. Simply releasing the support causes the insects to fall off. By repeatedly switching the support between the released and releasable states, insects continuously enter the temporary insect-containing space and fall through the drop mesh. This increases the efficiency and number of insects falling from the material transport carrier, thus solving the problems of incomplete insect excrement separation, high impurity content, and low efficiency in insect farming.

[0044] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

When a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to that other component.

[0046] It should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0047] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more pieces, unless otherwise explicitly specified.

[0048] To illustrate the technical solutions described in this application, the following detailed description is provided in conjunction with specific accompanying drawings and embodiments.

[0049] See Figures 1 to 6 This invention provides an insect excrement separation system, comprising:

[0050] The frame 100 may include a support column 101 and a frame 102 set on the support column 101. The frame 100 serves as the supporting foundation of the entire insect excrement separation system. Its shape and structure can be designed into any style and shape as needed.

[0051] Material conveying carrier 200 installed on frame 100, such as mesh belt (see Figure 7The material conveying carrier 200 has multiple insect dropping mesh holes 201 formed on it. The material conveying carrier 200 can be arranged in multiple layers along the height direction of the frame 100, or it can be a single layer of material conveying carrier 200. The material conveyed by the material conveying carrier 200 can specifically include a mixture of insects (such as fly larvae) and insect excrement. Insects falling from the insect dropping mesh holes 201 can achieve insect excrement separation.

[0052] The releasable support 1 can be attached to the lower part of the material conveying carrier 200 to be in a supporting state. In the supporting state, the releasable support 1 and the falling mesh form a temporary insect holding space. The insects contained in the temporary insect holding space can be supported on the releasable support 1. The releasable support 1 can move away from the material conveying carrier 200 to the release state. In the release state, the releasable support 1 releases its support for the insects contained in the temporary insect holding space.

[0053] Because when insects are on the material conveying carrier 200 with insect drop holes 201, under normal circumstances, most insects will try to stay on the material conveying carrier 200 by their own movement to avoid falling, rather than all of them burrowing down into the insect drop holes 201 to fall off. Therefore, the insect excrement separation system provided by this invention is designed with a releasable support 1. The releasable support 1 can be placed against the bottom of the material conveying carrier 200 to provide support. The releasable support 1 and the drop holes form a temporary insect-accommodating space. In this way, for the drop holes and the holes that cannot be simply understood as vertically continuous, the releasable support 1 "supports" these holes, forming a temporary insect-accommodating space. The presence of this device prevents insects from falling through the insect drop mesh 201. Instead, it encourages insects to avoid falling. A large number of insects will enter the insect drop mesh 201, which means they will enter the temporary insect holding space and be supported by the releasable support 1. At this time, simply releasing the releasable support 1 will cause the insects supported on it to fall off. By repeatedly switching the releasable support 1 between the supporting and releasing states, insects will continuously enter the temporary insect holding space and fall from the insect drop mesh 201 as the releasable support 1 is constantly in the releasing state. This can improve the falling efficiency and number of insects on the material conveying carrier 200, thus solving the problems of incomplete insect excrement separation, high impurity rate, and low efficiency in insect farming.

[0054] According to a preferred embodiment of the present invention, the insect excrement separation system includes an insect repelling device 2 disposed above the material conveying carrier 200. When the material conveying carrier 200 has multiple layers, an insect repelling device 2 is disposed above each layer of the material conveying carrier 200. The insect repelling device 2 is used to repel insects on the corresponding lower layer of the material conveying carrier 200 from falling into the insect drop mesh 201, or to repel insects on the material conveying carrier 200 from falling into the insect drop mesh 201 into a temporary insect holding space. The insect repelling device 2 is preferably disposed directly on the frame 100, but is not limited to being disposed on the frame 100.

[0055] It is understood that this insect excrement separation system is not limited to including the insect repelling device 2. The insect repelling device 2 can be used as other equipment. When insect excrement separation is required, the insect repelling device 2 can be introduced above the material conveying carrier 200. For example, the insect repelling device 2 can be brought above the material conveying carrier 200 by an automated drive device. When the insect excrement separation system is not working, the insect repelling device 2 can be removed or taken away.

[0056] Specifically, the insect repelling device 2 includes a light-based repelling device and / or a heat-based repelling device. The light-based repelling device is, for example, a fluorescent lamp, and the heat-based repelling device can be a heating element. The insect repelling device 2 either has the function of repelling insects by light or by heat, or it can have both functions simultaneously, such as an incandescent lamp. Furthermore, the insect repelling device 2 in this embodiment is not limited to light or heat repelling methods; any method capable of repelling insects is acceptable, such as acoustic repelling.

[0057] According to one embodiment of the present invention, the insect excrement separation system includes a guide support installed on the frame 100 for supporting a releasable support 1. The releasable support 1 is in a supported state when supported on the guide support, and in a released state when it leaves the guide support. That is, in this embodiment, the guide support is used to switch the releasable support 1 between the supported state and the released state. Specifically, the releasable support 1 can be driven to move so that it is supported on or away from the guide support, or the releasable support 1 can be supported on or away from the guide support by driving the guide support. It is even possible for both the releasable support 1 and the guide support to be designed as drivable moving parts. In this embodiment, when the releasable support 1 and the guide support move relative to each other, the guide support serves as a control carrier for switching the releasable support 1 between the supported state and the released state. Any design scheme that enables the releasable support 1 to be supported on or away from the guide support will fall within the protection scope of the present invention.

[0058] In another embodiment, the guide support can even be omitted. In this case, the insect excrement separation system includes an electronic control mechanism installed on the frame 100. The electronic control mechanism is connected to the releasable support 1 to control the releasable support 1 to switch between a supported state and a released state. This means that the electronic control mechanism can actively control the releasable support 1 to switch between a supported state and a released state, thus eliminating the need for the guide support as the control carrier for switching the releasable support 1 between the supported state and the released state. Specifically, the electronic control mechanism may include a motor, a drive cylinder, etc., and drive the releasable support 1 to move between the supported state and the released state through known linkage mechanisms, gear mechanisms, etc.

[0059] According to one embodiment of the present invention, the guide support extends along the conveying direction of the material conveying carrier 200. The guide support includes at least one of a guide rod 3, a guide plate, a guide block, and a guide wheel 15. The guide support is preferably fixedly installed on the frame 100. For example, when the guide support includes a guide rod 3, the guide rod 3 can be connected and supported above the riser 4, and the riser 4 can be installed on the frame 100. Thus, by driving the releasable support 1 to move, it can be supported on or away from the guide support. When the guide support includes a guide rod 3, a guide plate, and a guide block, the guide rod 3, guide plate, and guide block extend along the movement direction of the releasable support 1. See [reference needed]. Figure 9 When the guide support includes guide wheels 15, it can be multiple guide wheels 15 arranged along the movement direction of the releasable support 1. Figure 9 When the first cycle motion traction structure drives the releasable support 1 to move along the direction S, the releasable support 1 is guided along the rightmost guide wheel 15 to reach other guide wheels 15 and is in a supported state. After continuing to move along the direction S, it leaves the leftmost guide wheel 15 and is in a released state.

[0060] According to one embodiment of the present invention, a plurality of guide supports are arranged at intervals along the conveying direction of the material conveying carrier 200. When the releasable support 1 moves along the interval arrangement direction of the plurality of guide supports, it is in a supporting state when it is on a guide support and in a released state when it is in the interval between adjacent guide supports. The more guide supports are arranged at intervals so that the releasable support 1 can frequently switch between the supporting state and the released state at certain time intervals when it moves along the interval arrangement direction of the plurality of guide supports.

[0061] According to one embodiment of the present invention, the insect excrement separation system includes a first cyclic motion traction structure installed on the frame 100, a releasable support 1 installed on the first cyclic motion traction structure, and a material conveying carrier 200 fixed on the first cyclic motion traction structure. In this case, the material conveying carrier 200 and the releasable support 1 move synchronously with the first cyclic motion traction structure. Alternatively, the insect excrement separation system includes a second cyclic motion traction structure installed on the frame 100, and the material conveying carrier 200 is installed on the second cyclic motion traction structure. In this case, the material conveying carrier 200 and the releasable support 1 can move independently, preferably synchronously.

[0062] According to one embodiment of the present invention, the releasable support 1 is a support plate hinged to the first cyclic motion traction structure. In the supported state, the surface of the support plate is in contact with the material conveying carrier 200. When the support plate moves away from the guide support as the first cyclic motion traction structure moves, the support plate is in an upright state under its own gravity. The first cyclic motion traction structure may specifically include a chain drive assembly (including a drive motor 14, a gearbox, a first sprocket 5, a second sprocket 6, etc.), a chain 7 connected to the chain drive assembly, and an installation component disposed on one side of the chain 7. The releasable support 1 is installed on the installation component. The chain 7 is installed in a closed loop on the first sprocket 5 and the second sprocket 6. The installation component may be a hinge rod 8 disposed on one side of the chain 7. One end of the support plate is sleeved on the hinge rod 8 through an installation sleeve so that it can rotate around the hinge rod 8, thereby making the releasable support 1 (support plate) hinged to the hinge rod 8.

[0063] In addition, one end of the support plate can be hinged to the hinge rod 8 via a torsion spring. In this way, when the support plate moves away from the guide support member with the first cycle of motion traction structure, in addition to the support plate being in an upright state under its own gravity, the torsion spring can also apply a spring force to the support plate as it moves toward the vertical state, so that the support plate reaches the upright state more quickly and enhances the falling efficiency of the insect.

[0064] According to a specific embodiment of the present invention, multiple releasable support members 1 are arranged along the first cyclic motion traction structure, preferably arranged around the entire circumference. Specifically, a full circle of hinge rods 8 is installed at intervals along one side of the chain 7. Each hinge rod 8 is hinged with a releasable support member 1, for example, when the hinge is a support plate. Preferably, in the support state, the hinge rod 8 corresponding to the previous support plate is close to the next support plate. The mesh belt and mesh chain can wrap around the outside of the full circle of hinge rods 8 in the form of a closed loop structure. The corresponding hinge rod 8 and the releasable support member 1 are inside the closed loop structure formed by the mesh belt and mesh chain of the corresponding mesh chain. The mesh belt and mesh chain are fixed to the full circle of hinge rods 8 by the friction with the hinge rod 8 and the wrapping pressure of the mesh belt and mesh chain around the hinge rod 8.

[0065] In addition, the second cyclic motion traction structure can also be designed with reference to the first cyclic motion traction structure. Since the material conveying carrier 200 and the releasable support 1 are preferably moved synchronously with the first cyclic motion traction structure, the relevant technologies of the second cyclic motion traction structure will not be described in detail.

[0066] According to one embodiment of the present invention, the guide support includes an arc-shaped end structure. After the support plate moves away from the guide support with the first cyclic motion traction structure, it continues to move and can be supported again on the guide support along the arc-shaped end structure to be in a supported state. This can avoid excessive collision when the support plate is supported on the guide support again, and the support plate is flexibly guided. Specifically, when the guide support includes a guide rod 3, the arc-shaped end structure is a downwardly curved rod 9 formed at the end of the guide rod 3, for example... Figure 2 In the example, the first cycle of motion traction structure drives the releasable support 1 (support plate) to move from left to right. Figure 2 After the guide rod 3 on the left side leaves, the releasable support 1 (support plate) is in the released state (vertical). It continues to move to the right and gradually follows the guidance of the curved rod 9 until it finally reaches the desired position. Figure 2 The horizontal section of the right-side guide rod 3 is in a supported state (horizontally against the lower part of the material conveying carrier 200), for example... Figure 8 When the first cycle of motion traction structure drives the releasable support 1 to move along direction S, the releasable support 1 is guided along the right end of the guide rod 3 by the bent rod 9 to reach the horizontal section of the guide rod 3 and is in a supported state. After continuing to move along direction S, it leaves the left end of the guide rod 3 and is in a released state.

[0067] In addition, the insect excrement separation system also includes an insect drop platform 10, which is located at least below the releasable support 1 in the released state. When the releasable support 1 is in the released state, the insects supported on the releasable support 1 will fall from the releasable support 1 to the insect drop platform 10 and then fall from the insect drop platform 10 to other desired locations (e.g., to the insect recycling device 13 mentioned below). The insect drop platform 10 can be arranged at multiple points or at one point along the horizontal direction, corresponding to the arrangement of each layer of material conveying carrier 200, so as to realize the discharge of insects at any position and any number of discharge points.

[0068] In addition, the insect excrement separation system also includes a material scraper 11, which is provided for the multi-layer material conveying carrier 200 and extends above the corresponding material conveying carrier 200. The material scraper 11 can scrape off the outer layer of material above the corresponding material conveying carrier 200.

[0069] According to one embodiment of the present invention, the first end of the material scraper 11 extends above the end of the corresponding mesh chain in the direction of movement, and the second end of the material scraper 11 is located outside the frame 100. The material scraper 11 is arranged obliquely downward from the first end to the second end. In this way, when the material containing insects and insect excrement runs to the end of the mesh chain in the direction of movement, the outermost layer of insect excrement is scraped off, exposing the insects and insect excrement inside, which is conducive to the further separation of the lower layer of insects and insect excrement. When the material passes through each layer of mesh chain, there is a falling process, which can break up the material for further separation.

[0070] In other embodiments, in addition to extending above both ends of the mesh chain in the length direction, the material scraper 11 can extend above any suitable position of the mesh chain, such as above both ends of the mesh chain in the width direction, or any position in the middle of the mesh chain.

[0071] According to one embodiment of the present invention, the material scraper 11 is connected to the frame 100 through an adjustment structure. The adjustment structure can adjust the distance between the first end of the material scraper 11 and the corresponding mesh chain. The height of the first end of the material scraper 11 above the end of the mesh chain in the direction of movement also changes accordingly, thereby flexibly adjusting the height of the material to be scraped.

[0072] According to one embodiment of the present invention, the adjustment structure includes an elongated hole 103 extending along the height direction of the frame 100. The first end of the material scraper 11 can be fixed at different positions along the height direction of the frame 100 in the elongated hole 103. The first end of the material scraper 11 is locked at different positions in the elongated hole 103 by a threaded rod or the like in conjunction with a nut. Of course, the adjustment structure of the present invention is not limited to the elongated hole 103. For example, a scheme that uses a cylinder, a lead screw nut, or the like to connect the material scraper 11 to adjust the distance between the first end of the material scraper 11 and the corresponding mesh chain is also possible.

[0073] In addition, the insect excrement separation system includes an insect excrement collection device 12 (e.g., an insect excrement collection box, a container, etc.) located on the outside of the frame 100, which is located below the second end of the material scraper 11.

[0074] According to a preferred embodiment of the present invention, the upper surface of the insect drop platform 10 is arranged obliquely downward toward the edge of the insect drop platform 10. After the insects on the material conveying carrier 200 enter the insect drop mesh 201 and eventually fall from the releasable support 1 or directly from the insect drop mesh 201 to the corresponding insect drop platform 10, since the upper surface of the insect drop platform 10 is arranged downward toward the edge of the insect drop platform 10, it is convenient for the insects on the insect drop platform 10 to slide off the edge of the material conveying carrier 200. For this purpose, an insect recycling device 13 (e.g., an insect collection box, a container, etc.) can be arranged below the edge of the insect drop platform 10. The insect recycling device 13 is arranged on one side of the frame 100 to receive the insects leaving the insect drop platform 10.

[0075] According to a specific embodiment of the present invention, the insect dropping platform 10 includes two inclined plates, which are respectively arranged inclined downwards toward both sides of the multi-layer material conveying carrier 200, and the highest points of the two inclined plates are connected to each other; or, the insect dropping platform 10 includes two inclined plates and a flat plate connected between the two inclined plates, which are respectively arranged inclined downwards toward both sides of the multi-layer material conveying carrier 200, and the highest points of the two inclined plates are respectively connected to the flat plate; or, the upper surface of the insect dropping platform 10 is an arc-shaped surface that curves downwards toward both sides of the multi-layer material conveying carrier 200. Of course, the specific structural form of the insect dropping platform 10 is not limited to this. Any structure that can conveniently guide the insects to slide off its edge is acceptable. Even the way the insects leave the insect dropping platform 10 is not limited to the upper surface of the insect dropping platform 10 being arranged inclined downwards toward the edge of the insect dropping platform 10. A power mechanism such as a conveyor belt can also be used to make the insects leave the insect dropping platform 10.

[0076] The above description is merely an optional embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
