[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: Figure 1-7As shown, this utility model provides a treatment device for treating marigold meal using black soldier flies, including a treatment box 1. The treatment box 1 is a hollow structure with an open top. Several moisture-proof seats 11 are fixedly installed at the bottom of the treatment box 1. By setting the moisture-proof seats 11, the moisture-proof performance of the treatment box 1 can be improved. A treatment component 2 is provided inside the cavity of the treatment box 1. An escape-proof component 3 is provided at the open end of the treatment box 1. By setting the treatment component 2 and the escape-proof component 3, black soldier flies and marigold meal can be placed in the treatment component 2. The escape-proof component 3 can prevent black soldier flies from escaping. Black soldier flies are randomly selected periodically, and their weight, length, and width are measured. At the end of the experiment, marigold meal samples before conversion, insect excrement samples after conversion, and insect bodies are collected. The marigold meal reduction rate, biological conversion rate, insect body indicators, and nutrient content of insect excrement are measured respectively. Biological combinations with better conversion effects are compared and screened, providing a certain theoretical basis for subsequent research and industrial processing.

[0031] The processing component 2 includes an inner box 21, which is slidably disposed within the cavity of the processing box 1. Black soldier flies and marigold meal can be placed inside the inner box 21. A U-shaped handle 22 is fixedly installed at one end of the inner box 21, allowing operators to pull out the inner box 21 for easy inspection of the black soldier flies and marigold meal. Insertion blocks 23 are fixedly installed on both sides of the inner box 21, and two insertion slots 24 are formed within the cavity of the processing box 1. The inner walls of the plug-in block 23 and the plug-in groove 24 are movably connected. By setting the plug-in block 23 and the plug-in groove 24, when the plug-in block 23 is horizontally inserted into the plug-in groove 24, the inner box 21 can be stably inserted into the processing box 1. The cavity of the processing box 1 is provided with several arc-shaped limiting blocks 25. Several arc-shaped grooves 26 are opened on both the upper and lower surfaces of the plug-in block 23. The inner walls of the arc-shaped limiting blocks 25 and the arc-shaped grooves 26 are in movable contact. By setting the arc-shaped limiting blocks 25 and the arc-shaped grooves 26, when... After the plug-in block 23 is horizontally inserted into the plug-in slot 24, the arc-shaped limiting block 25 enters the arc-shaped groove 26. The arc-shaped limiting block 25 can limit the plug-in block 23 through the arc-shaped groove 26. Without external force, the plug-in block 23 will not slide on its own. Several slots 27 are opened in the cavity of the processing box 1. The slots 27 are connected to the plug-in slot 24. A Z-shaped elastic element 28 is fixedly installed on the inner wall of the slot 27. One end of the Z-shaped elastic element 28 is connected to the arc-shaped limiting block 25. The fixed connection is achieved by setting the slot 27 and the Z-shaped elastic element 28. The arc-shaped limiting block 25 can retract into the slot 27, and the Z-shaped elastic element 28 can push the arc-shaped limiting block 25 to always fit against the inner wall of the arc-shaped groove 26. When the inner box 21 is pulled away from the processing box 1, the plug-in block 23 moves horizontally in the plug-in slot 24. The plug-in block 23 can separate the arc-shaped limiting block 25 from the arc-shaped groove 26 through the arc-shaped groove 26, and the arc-shaped limiting block 25 can cause the Z-shaped elastic element 28 to retract.

[0032] The escape prevention component 3 includes a mesh screen 31. The open end of the treatment box 1 is provided with a U-shaped groove 32. The mesh screen 31 passes through the U-shaped groove 32 and is in contact with the inner wall of the U-shaped groove 32. By setting the mesh screen 31 and the U-shaped groove 32, the mesh screen 31 can prevent the black soldier fly from escaping. The mesh screen 31 can be fixed in the U-shaped groove 32 to seal the open end of the treatment box 1, while ensuring that oxygen can enter the inner box 21 normally.

[0033] A spiral-shaped pressure plate 33 is slidably arranged inside the spiral-shaped groove 32. An anti-slip pad 34 is fixedly arranged on the lower surface of the spiral-shaped pressure plate 33. The lower surface of the anti-slip pad 34 is in contact with the upper surface of the mesh 31. Several counterweights 331 are fixedly arranged on the upper surface of the spiral-shaped pressure plate 33. By setting the spiral-shaped pressure plate 33, the anti-slip pad 34 and the counterweights 331, the spiral-shaped pressure plate 33 can press the mesh 31 into the spiral-shaped groove 32 through the anti-slip pad 34. The counterweights 331 can improve the stability after pressing.

[0034] Several sleeves 35 are fixedly installed at the open end of the processing box 1. A pull rod 36 is movably inserted inside each sleeve 35. One end of the pull rod 36 is fixedly connected to the upper surface of the U-shaped pressure plate 33. A movable disc 37 is fixedly installed at one end of the pull rod 36. A spring 38 is sleeved on the outside of the pull rod 36. One end of the spring 38 is fixedly connected to the upper surface of the movable disc 37, and the other end of the spring 38 is fixedly connected to the top wall of the sleeve 35. A handle 39 is fixedly installed at the other end of the pull rod 36. By configuring a pull rod 36, a movable disc 37, a spring 38, and a handle 39, when the pull rod 36 is pulled upwards via the handle 39, the pull rod 36 causes the movable disc 37 and the return plate 33 to rise vertically, and the spring 38 to contract, thereby releasing the pressure on the mesh 31. The mesh 31 can then be removed for disassembly or replacement. When the handle 39 is released, the spring 38 extends and returns to its original position, causing the return plate 33 to descend vertically via the movable disc 37 and the pull rod 36, thus pressing the mesh 31 back into place.

[0035] Working principle: When in use, the operator pulls the inner box 21 away from the processing box 1 by using the U-shaped handle 22, so that the inner box 21 is separated from the processing box 1. At the same time, the plug block 23 gradually separates from the plug groove 24. Meanwhile, the arc-shaped limiting block 25 is squeezed and retracted into the groove 27, and the Z-shaped elastic element 28 retracts until the inner box 21 is completely separated from the processing box 1.

[0036] Subsequently, the operators placed a certain amount of black soldier fly larvae and marigold meal into the inner box 21. At this time, the inner box 21 was inserted into the cavity of the processing box 1. The insertion block 23 was horizontally inserted into the insertion groove 24. The arc-shaped limiting block 25 was always in contact with the inner wall of the arc-shaped groove 26 under the reset of the Z-shaped elastic element 28, thus limiting the insertion block 23. Without the action of external force, the inner box 21 slid by itself in the processing box 1.

[0037] Finally, by pulling the lever 36 vertically upward with the handle 39, the lever 36 causes the movable plate 37 and the back-shaped pressure plate 33 to rise vertically, the spring 38 contracts, and then the mesh 31 passes through the back-shaped groove 32. After releasing the handle 39, the spring 38 extends and returns to its original position. The spring 38 causes the back-shaped pressure plate 33 and the anti-slip pad 34 to fall vertically through the movable plate 37 and the lever 36, pressing the mesh 31 tightly against the opening end of the processing box 1, sealing the opening end of the processing box 1, preventing the black soldier fly from escaping while ensuring the normal entry of oxygen.

[0038] During the treatment process, black soldier flies were randomly selected periodically to measure their weight, length, and width. At the end of the experiment, marigold meal samples before conversion, insect excrement samples after conversion, and insect bodies were collected. The marigold meal reduction rate, bioconversion rate, insect body indicators, and nutrient content of insect excrement were measured. Biological combinations with better conversion effects were compared and screened to provide a certain theoretical basis for subsequent research and industrialized treatment.

The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.
