Description

Technical Field

[0001] The present application relates to the technical field of insect breeding, and more specifically, to a multi-layer organic solid waste insect breeding system. Background Art

[0002] At present, with the continuous expansion of the scale of modern breeding industry, the generation amount of livestock and poultry manure has also been increasing. At the same time, the development of urbanization has also generated a large amount of food waste. On the one hand, this affects the development of the industry, and on the other hand, it seriously affects the ecological environment. The traditional technology for composting treatment of organic solid waste has a long time and low efficiency. Using insects to treat organic solid waste such as livestock and poultry manure and food waste can not only convert organic substances into its own nutrients, but also produce high-protein nutritious feed, realizing the organic recycling of biological waste.

[0003] The existing insect breeding systems mainly include single-layer breeding in artificial greenhouses and multi-layer breeding. Although the single-layer breeding in artificial greenhouses has a simple structure, it has a large floor area, requires a lot of labor, and is easily affected by the external environmental climate. The multi-layer breeding can be divided into artificial multi-layer breeding and mechanized multi-layer breeding. Although the artificial multi-layer breeding reduces the floor area, it requires manual or mechanical feeding, breeding and discharging management for each layer of feeding trays, with a large working intensity and a harsh working environment. The existing mechanized multi-layer breeding also has problems such as low breeding efficiency, complex equipment structure and high cost. Summary of the Invention

[0004] The main purpose of the present invention is to provide a multi-layer organic solid waste insect breeding system, aiming to solve the technical problems of large floor area and low breeding efficiency in the existing insect breeding systems.

[0005] To achieve the above object, the technical solution adopted by the present invention is: a multi-layer organic solid waste insect breeding system, which includes:

[0006] A support frame;

[0007] A multi-layer material accommodating structure arranged on the support frame in the up and down direction;

[0008] A scraping mechanism, including a scraping member that can at least move relative to each material accommodating structure above the lowermost material accommodating structure in the multi-layer material accommodating structure, so that the scraping member can at least scrape the upper surfaces of each material accommodating structure above the lowermost material accommodating structure in the multi-layer material accommodating structure;

[0009] Each material accommodating structure above the lowermost material accommodating structure in the multi-layer material accommodating structure has a plurality of dropping gaps, and the dropping gaps on adjacent material accommodating structures are staggered in the up and down direction;

[0010] The object-insect separation auxiliary mechanism is the material containing structure of the lowermost layer or the material containing structure arranged at the lowermost layer.

[0011] Furthermore, the scraping mechanism includes a scraping drive mechanism that is transmission-connected to the scraping member to drive the scraping member to scrape the upper surface of each material containing structure; and / or each material containing structure above the lowest material containing structure in the multi-layer material containing structure is movably arranged, and the multi-layer organic solid waste insect breeding system includes a material containing structure driving device to drive each material containing structure to move so that the upper surface of each material containing structure performs a scraping movement relative to the scraping member.

[0012] Furthermore, the scraping member is a scraper, and when the scraper performs a scraping operation on the upper surface of the corresponding material containing structure, the lower surface of the scraper is in full contact with the upper surface of the corresponding material containing structure.

[0013] Furthermore, a scraper is arranged above each material containing structure above the lowest material containing structure in the multi-layer material containing structure.

[0014] Further, each material containing structure is a material tray, and the falling gap is a through hole arranged on the material tray; or, each material containing structure includes a plurality of material trays arranged at intervals in the horizontal direction, and the falling gap is the gap between adjacent material trays.

[0015] Furthermore, the material containing structure at the bottom layer is a grid containing structure to serve as the object-insect separation auxiliary mechanism; or, the object-insect separation auxiliary mechanism includes a lighting insect repellent device or a sonic insect repellent device arranged above the material containing structure at the bottom layer; or, the object-insect separation auxiliary mechanism includes a heating device arranged at the material containing structure at the bottom layer.

[0016] Furthermore, when the object-insect separation auxiliary mechanism includes a heating device disposed on the material containing structure at the lower layer, the heating device runs through the middle of the material containing structure.

[0017] Further, the scraper is arranged above the material containing structure at the bottom layer; or, the material containing structure at the bottom layer is rotatably mounted on the support frame and can be rotated at least 45°.

[0018] Furthermore, the multi-layer organic solid waste insect breeding system includes a closed warehouse body and an airflow generating device, the support frame, material containing structure and object-insect separation auxiliary mechanism are all arranged in the closed warehouse body, and the closed warehouse body is provided with an airflow inlet and an airflow outlet.

[0019] Further, the upper end and the lower end of the closed bin body are respectively provided with the air inlets, and the middle part in the height direction of the closed bin body is provided with the air outlet. The air flow generating device is used to generate an air flow that enters from the air inlets, passes through the dropping gap, and flows out from the air outlet.

[0020] Further, the scraping drive mechanism is a cylinder, an electric cylinder or a hydraulic cylinder.

[0021] Further, the multi-layer organic solid waste insect breeding system includes a feeding device and a discharging device. The feeding device is arranged above the material accommodating structure at the uppermost layer in the multi-layer material accommodating structure, and the discharging device is arranged below the material accommodating structure at the lowermost layer in the multi-layer material accommodating structure.

[0022] The beneficial effects of the multi-layer organic solid waste insect breeding system provided by this application are as follows:

[0023] Since each material accommodating structure above the material accommodating structure at the lowermost layer in the multi-layer material accommodating structure has a plurality of dropping gaps, the dropping gaps on adjacent material accommodating structures are staggered in the up-and-down direction respectively, and the scraping member performs scraping operations on the upper surfaces of each material accommodating structure, so the scraping member only needs to perform a short-distance scraping operation on the upper surface of the corresponding material accommodating structure to make the materials on the material accommodating structure fall onto the next lower layer of the material accommodating structure. On the one hand, the gradual dropping of the materials can enable the materials to have a certain residence time, so that the insects in the materials can fully loosen the materials. On the other hand, precisely because each material accommodating structure has a plurality of dropping gaps, the scraping member only needs to perform a short-distance scraping operation to make the materials on the material accommodating structure fall onto the next lower layer of the material accommodating structure. Therefore, a short scraping operation makes the materials fall onto the next lower layer of the material accommodating structure in small portions one by one, and there will be no situation of a large amount of material accumulation caused by the material accommodating structure discharging materials from one dropping position. Therefore, the distance between adjacent material accommodating structures can be made very short, usually less than 50 cm. In this way, the entire multi-layer material accommodating structure can be arranged more closely, which enables the multi-layer organic solid waste insect breeding system provided by the present invention to process materials with a greater density, and greatly improves the efficiency of material processing.

[0024] In addition, by setting up the material-insect separation auxiliary mechanism, the separation of the materials and insects on the material accommodating structure at the lowermost layer can be automatically realized without manual operation, which is convenient for realizing the fully automatic insect breeding and material processing of the entire multi-layer organic solid waste insect breeding system.

[0025] In a further solution, when the scraper performs a scraping operation on the upper surface of the corresponding material accommodating structure, the lower surface of the scraper is in full contact with the upper surface of the corresponding material accommodating structure, so as to ensure that the materials on the material accommodating structure can be completely scraped off, greatly improving the efficiency of the materials falling layer by layer and ensuring that there is almost no residual material on the material accommodating structure.

[0026] In a further solution, the system includes a closed bin body and an air flow generating device, which can realize fully enclosed automated insect breeding. Although the system is of a multi-layer structure, through the dropping gap and the air flow generating device, it can ensure that each layer of the material accommodating structure has excellent air supply, meeting the requirements of insects such as maggots or black soldier flies for temperature, oxygen and humidity.

Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present application, "a plurality of" means two or more unless otherwise specifically defined.

[0045] In order to illustrate the technical solutions described in the present application, the following will be described in detail with reference to specific drawings and embodiments.

[0046] See Figures 1 to 5 , an embodiment of the present invention provides a multi - layer organic solid waste insect breeding system, which includes:

[0047] Support frame 1, as a support member for a multi - layer material accommodating structure, etc., and the material should meet certain stiffness and strength requirements;

[0048] A multi - layer material accommodating structure arranged on the support frame 1 in the up - down direction;

[0049] The scraping mechanism includes a scraping operation capable of at least scraping the upper surface of each material containing structure above the lowest material containing structure in the multi-layer material containing structure;

[0050] Each material containing structure above the lowest material containing structure in the multi-layer material containing structure has a plurality of drop gaps 2, and the drop gaps 2 on adjacent material containing structures are staggered in the up-down direction;

[0051] The scraping mechanism includes a scraping drive mechanism that is transmission-connected to the scraping member 3 to drive the scraping member 3 to scrape the upper surface of each material containing structure; and / or each material containing structure above the lowest material containing structure in the multi-layer material containing structure is movably arranged, and the multi-layer organic solid waste insect breeding system includes a material containing structure driving device to drive each material containing structure to move so that the upper surface of each material containing structure performs a scraping movement relative to the scraping member 3, that is, the scraping member 3 and the material containing structure generate a relative scraping movement, that is, this paragraph includes three situations: the first, the material containing structure and the scraping member 3 can be movably arranged; the second, the material containing structure is movably arranged and the scraping member 3 is fixedly arranged; the third, the material containing member is fixedly arranged and the scraping member 3 is movably arranged;

[0052] The object-insect separation auxiliary mechanism is the material containing structure at the bottom layer or is arranged at the material containing structure at the bottom layer.

[0053] Since each material containing structure above the material containing structure of the lowest layer in the multi-layer material containing structure has a plurality of falling gaps 2, the falling gaps 2 on the adjacent material containing structures are staggered in the up-down direction, and the scraper 3 performs a scraping operation on the upper surface of each material containing structure, the scraper 3 only needs to perform a short distance scraping operation on the upper surface of the corresponding material containing structure to make the material on the material containing structure fall to the material containing structure of the next layer. On the one hand, the falling of the material layer by layer can realize a certain residence time of the material, so that the insects of the material insects can fully loosen the material. On the other hand, because each material containing structure has a plurality of falling gaps 2, The scraper 3 can make the material on the material containing structure fall to the material containing structure of the next layer by performing a short-distance scraping operation. Therefore, a short-distance scraping operation causes the material to fall to the material containing structure of the next layer in small portions layer by layer, and there will be no situation in which a large amount of material is accumulated due to the material containing structure dropping from one falling position. Therefore, the spacing between adjacent material containing structures can be made very short, usually less than 50 cm, so that the entire multi-layer material containing structure is arranged more closely, so that the multi-layer organic solid waste insect breeding system provided by the present invention can accommodate materials of a larger density, greatly improving the efficiency of material processing.

[0054] According to one embodiment of the present invention, taking the scraper 3 being movably arranged as an example, the scraper mechanism includes a scraper drive mechanism transmission-connected to the scraper 3. The specific scraper drive mechanism can be a motor driving a gear, a sprocket or a pulley and other mechanisms to drive the scraper 3 to perform reciprocating motion, or a cyclic motion, etc. above the material containing structure.

[0055] According to a preferred embodiment of the present invention, the scraping drive mechanism is a cylinder 4, an electric cylinder or a hydraulic cylinder. Taking the cylinder 4 as an example, the cylinder body or push rod of the cylinder 4 is connected to the scraper 3, and the reciprocating motion of the scraper 3 is realized by the extension and contraction of the cylinder 4. The cylinder 4 has the characteristics of low cost and strong reliability and stability. Specifically, the push rod of the cylinder 4 is connected to a long rod 5, and a plurality of scrapers 3 are arranged on the long rod 5 at intervals. The number and intervals of the scrapers 3 are uniquely arranged corresponding to the number and intervals of the plurality of drop gaps 2 on each layer of the material containing structure, which is equivalent to that the interval between the two drop gaps 2 has a scraper 3 operating, which can shorten the stroke of the cylinder 4 and improve the material scraping efficiency. From the above, it can be seen that the scraping drive mechanism is obviously not limited to the cylinder 4.

[0056] The organic solid waste in the multi-layer organic solid waste insect breeding system provided by the present invention may be livestock and poultry manure or other suitable materials, and the insects may be maggots or other suitable insects.

[0057] According to one embodiment of the present invention, the scraper 3 is a scraper. When the scraper is scraping the upper surface of the corresponding material containing structure, the lower surface of the scraper is in full contact with the upper surface of the corresponding material containing structure, thereby ensuring that the material on the material containing structure can be completely scraped off (and falls to the material containing structure of the next layer through the falling gap 2).

[0058] According to one embodiment of the present invention, a scraper 3 is arranged above each material containing structure above the lowest material containing structure in the multi-layer material containing structure, and each scraper 3 can be respectively equipped with a driving device such as a scraper driving mechanism (motor), or each scraper 3 can also be driven by a total scraper driving mechanism (motor).

[0059] According to an embodiment of the present invention, each material containing structure is a material tray 6 , and the falling gap 2 is a through hole provided on the material tray 6 .

[0060] According to another embodiment (preferred) of the present invention, each material containing structure includes a plurality of material trays 6 spaced apart in a horizontal direction, and the falling gap 2 is a gap between adjacent material trays 6 .

[0061] According to the first embodiment of the present invention, the lowermost material accommodating structure (tray 6) is a grid accommodating structure to serve as an insect-material separation assisting mechanism. The grid accommodating structure is, for example, a grid cloth (serving as tray 6), which facilitates the free wriggling and falling of insects, so as to separate insects from materials on the lowermost material accommodating structure.

[0062] According to the second embodiment of the present invention, the insect-material separation assisting mechanism includes a lighting insect repellent device or a sound wave insect repellent device disposed above the material accommodating structure at the lower layer, so as to prompt insects to escape from above the material accommodating structure through light or sound.

[0063] According to the third embodiment of the present invention, the insect-material separation assisting mechanism includes a heating device 7 disposed on the lowermost material accommodating structure, so as to prompt insects to escape from above the material accommodating structure through heating.

[0064] See Figure 3 , in the third embodiment of the present invention, as a preferred mode, when the insect-material separation assisting mechanism includes a heating device 7 disposed on the lowermost material accommodating structure, the heating device 7 penetrates through the middle part of the material accommodating structure. For example, the heating device 7 is an electric heating plate installed at the bottom of the lowermost material accommodating structure (tray 6). The electric heating plate is designed with a middle convex structure. The middle convex part 71 of the electric heating plate penetrates and is embedded into the middle part of the material accommodating structure (tray 6) to directly contact the material, and the peripheral part 72 of the electric heating plate abuts against the bottom surface of the periphery of the material accommodating structure (tray 6). In this way, once the heating plate is started, the middle part of the material on the tray 6 directly contacts the middle convex part of the heating plate and quickly heats up, prompting the insects in the material to quickly escape to the surroundings.

[0065] See Figure 5 , according to an embodiment of the present invention, a scraping member 3 is arranged above the lowermost material accommodating structure. In this case, the material on the lowermost material accommodating structure is scraped off by the scraping member 3. According to another embodiment of the present invention, the lowermost material accommodating structure (tray 6) is rotatably installed on the support frame 1 and can rotate at least 45°. For example, 45°, 60°, 180°, etc. In this case, after the lowermost material accommodating structure rotates, the material on it can be completely dumped, so there is no need to equip a scraping member 3 above the lowermost material accommodating structure. The material accommodating structure can be specifically installed on the support frame 1 through a rotating shaft 8.

[0066] According to an embodiment of the present invention, a multi-layer organic solid waste insect breeding system includes a closed bin body 8 and an air flow generating device. An air flow inlet 81 and an air flow outlet 82 are provided on the closed bin body 8. The closed bin body 8 can be provided with heat-insulating wall panels and a ventilation system, which can ensure the oxygen supply and temperature control inside the system. The positions of the air flow inlet 81 and the air flow outlet 82 are not particularly limited. For example, the air flow inlet 81 is arranged above the closed bin body 8, and the air flow outlet 82 is arranged below the closed bin body 8, or the air flow inlet 81 is arranged below the closed bin body 8, and the air flow outlet is arranged above the closed bin body 8, or the air flow inlet 81 and the air flow outlet 82 are respectively arranged at any suitable positions on the closed bin body 8, which are all acceptable.

[0067] See Figure 2 , according to a preferred embodiment of the present invention, the upper end and the lower end of the closed bin body 8 respectively have air flow inlets 81, and the middle part in the height direction of the closed bin body 8 has an air flow outlet 82. The air flow generating device is used to generate an air flow that enters from the air flow inlet 81 and passes through the drop gap 2 and flows out from the air flow outlet 82. The advantage of this preferred embodiment is that since the number of layers of the multi-layer material accommodating structure is relatively large, the air flow outlet 82 is arranged in the middle in the height direction of the closed bin body 8. The air flow is introduced through the two air flow inlets 81 at the upper end and the lower end and led out from the air flow outlet 82 in the middle of the height direction of the closed bin body 8. In this way, the number of layers that the air passes through can be reduced by half, which is beneficial to cooling the environment inside the closed bin body 8. In addition, in actual production applications, feeding devices 9, discharging devices 10, etc. that are connected to the outside of the closed bin body 8 need to be arranged at the upper end and the lower end of the closed bin body 8. Therefore, the upper end and the lower end of the closed bin body 8 cannot be made absolutely sealed. So just use the upper end and the lower end of the closed bin body 8 as the air flow inlets 81, which is beneficial to forming a negative pressure in the whole system.

[0068] According to a preferred embodiment of the present invention, the support frame 1, the material accommodating structure and the material-insect separation auxiliary mechanism are all arranged in the closed bin body 8. Through the closed bin body 8, closed breeding and management of organic solid waste insects are realized, and the environmental pollution is small. Specifically, the air flow generating device can be a centrifugal fan, so that air enters the closed bin body 8 from the top layer, passes through the gaps between the accommodating members layer by layer, and then is discharged out of the system. The air can also enter the closed bin body 8 from the lower layer and be discharged from the top layer of the closed bin body 8. Through the optimized design of this structure, although the system is a multi-layer structure, it can ensure that each layer of the material accommodating structure has excellent air supply, thus ensuring the requirements of maggots for temperature, oxygen and humidity.

[0069] According to a preferred embodiment of the present invention, a plurality of dropping gaps 2 on each material accommodating structure are arranged at equal intervals: so that the airflow generated by the airflow generating device forms a plurality of airflow paths arranged in an S shape at equal intervals when passing through the dropping gaps 2 on each material accommodating structure. With such a design, the airflow can flow evenly in the material accommodating structure, ensuring a more excellent air supply requirement. Of course, even if the airflow generated by the airflow generating device does not form an S-shaped airflow path when passing through the dropping gaps 2 on each material accommodating structure, it is also acceptable.

[0070] In addition, the multi-layer organic solid waste insect breeding system includes a feeding device 9 and a discharging device 10. The feeding device 9 is arranged above the material accommodating structure at the uppermost layer in the multi-layer material accommodating structure, and the discharging device 10 is arranged below the material accommodating structure at the lowermost layer in the multi-layer material accommodating structure. Specifically, the feeding device 9 includes a material pump, an output pipeline, a hopper, etc., and the discharging device 10 may include a conveyor belt and its driving member.

[0071] During specific operation, taking the example of the breeding system using food waste to breed maggots: The solid residue of the food waste after three-phase separation is pumped into the material accommodating structure at the uppermost layer of the system, and the hatched maggot larvae are evenly added to the material. After several hours, the scraping mechanism is started to completely scrape the material and maggots on the material accommodating structure at the uppermost layer to the second-layer material accommodating structure. After an interval of several hours, the material on the second-layer material accommodating structure is completely scraped to the third-layer material accommodating structure, and so on in a cycle. When the material and maggots reach the material accommodating structure at the lowermost layer, the insects are first separated from the material through the material-insect separation auxiliary mechanism. Taking the embodiment of the heating device 7 as an example, the heating device 7 is started to raise the temperature of the material accommodating structure at the lowermost layer, and the maggots escape from the material and fall into the conveyor belt below through the gaps between the material accommodating structures at the lowermost layer (that is, the material accommodating structure at the lowermost layer also refers to the layout of the material accommodating structures above it, and it may not be the same as the layout of the material accommodating structures above it). The conveyor belt starts to operate to convey the maggots into the insect collection box; when all the maggots in the material are separated, the scraping mechanism is started, and the scraping member 3 scrapes the remaining material onto the conveyor belt below, and the conveyor belt starts to convey the material into the manure collection box. Thus, the maggots and the insect manure are separated.

[0072] The above are only optional embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present application shall be included within the protection scope of the present application.
