[0028] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0029] like Figure 1 As shown, this utility model provides a multi-layer feeder for organic waste, which is used to feed multiple conversion boxes of a multi-layer conversion rack.

[0030] The multi-layer conversion rack 1 includes a frame, which can be made of hollow metal rods spliced ​​together. Multiple conversion boxes 11 are fixed on the frame. The multiple conversion boxes 11 are arranged at intervals along the height direction of the multi-layer conversion rack 1. The conversion boxes 11 can be fixed to the frame by bolts, glass glue or plug-in.

[0031] like Figure 1As shown, the multi-layer feeder includes a feeding frame 24, a lifting mechanism 23, a discharge bin 25, a feeding mechanism 26, and multiple receiving mechanisms. The lifting mechanism 23, discharge bin 25, and feeding mechanism 26 are all mounted on the feeding frame 24. The discharge bin 25 is positioned between the lifting mechanism 23 and the feeding mechanism 26. The lifting mechanism 23 is used to lift the material to the top of the discharge bin 25, and the multiple receiving mechanisms are used to guide the material onto the feeding mechanism 26. Both the lifting mechanism 23 and the feeding mechanism 26 are belt conveyors, and all three mechanisms are controlled by a controller.

[0032] like Figure 1 As shown, the right end of the lifting mechanism 23 is fixed to the lifting block 21, and a barrier 22 is provided on the right end of the lifting mechanism 23. The barrier 22 can block the material falling into the lifting mechanism 23 and prevent it from falling.

[0033] like Figure 3 , 4 As shown, the top of the material discharge bin 25 is flared, and the top of the material discharge bin 25 is connected to the left end of the lifting mechanism 23. The material discharge bin 25 has a discharge port 251 on the side near the feeding mechanism 26. The discharge port 251 extends from the position of the material discharge bin 25 near the flared structure to the bottom of the material discharge bin 25.

[0034] like Figure 1 As shown, the feeding mechanism 26 includes multiple feeding conveyors 261, which are arranged correspondingly to multiple conversion boxes 11 for feeding materials into each conversion box 11. Figure 2 As shown, the receiving mechanism is arranged at the discharge port 251. Multiple receiving mechanisms are arranged corresponding to multiple feeding conveyors 261. The receiving mechanism includes a receiving drive mechanism and a receiving plate 27. The receiving plate 27 is provided with a receiving position and a clearance position. The receiving drive mechanism is used to control the receiving plate 27 to move to the receiving position to receive the material falling from the dropping bin 25 to the feeding conveyor 261, or to control the receiving plate 27 to move to the clearance position to avoid the material falling from the dropping bin 25.

[0035] like Figure 2 As shown, the top receiving plate 27 is in the clearance position, while the other receiving plates 27 are in the receiving position. Material can fall onto the second (from top to bottom) feeding conveyor 261 through the second (from top to bottom) receiving plate 27, thereby conveying the material to the corresponding conversion box 11. When it is necessary to feed other conversion boxes 11, the corresponding receiving plate 27 can be controlled to move to the receiving position, and the receiving plate 27 above it can move to the clearance position, thus realizing the feeding of the corresponding conversion box 11. This utility model realizes the feeding of multiple conversion boxes 11, and the feeding structure is simple and easy to maintain.

[0036] In some embodiments, the receiving drive mechanism can be installed on the feeding rack 24, the dropping bin 25, or the feeding mechanism 26. One end of the receiving plate 27 is provided with a rotating shaft, which is arranged close to the feeding conveyor 261. The receiving drive mechanism controls the rotation of the receiving plate 27 through the rotating shaft, so that the other end of the receiving plate 27 turns into the dropping bin 25 to receive the material. Figure 5 The material receiving drive mechanism is not shown in the figure. The material receiving drive mechanism can be a geared motor. The geared motor is bolted to the feeding frame 24. The output end of the geared motor is connected to one end of the rotating shaft. The rotating shaft is arranged at the discharge port 251 of the discharge bin 25. The other end of the rotating shaft can be rotatably connected to the discharge bin 25. The rotation of the receiving plate 27 can be controlled by the geared motor. When the receiving plate 27 rotates to the vertical direction, the receiving plate 27 is in the clearance position. When the receiving plate 27 rotates to the point where one end abuts against the inner wall of the discharge bin 25, the receiving plate 27 is in the receiving position.

[0037] In addition, in some embodiments, the receiving plate 27 can also receive or avoid materials through linear movement. For example, the receiving plate 27 is arranged at an angle, and the receiving drive mechanism controls the receiving plate 27 to move horizontally into the discharge bin 25 until the upper end of the receiving plate 27 abuts against the inner wall of the discharge bin 25. At this time, the receiving plate 27 is in the receiving position. The receiving drive mechanism then controls the receiving plate 27 to move horizontally outside the discharge bin 25 until the upper end of the receiving plate 27 is flush with the discharge port 251 of the discharge bin 25. At this time, the receiving plate 27 is in the avoiding position. The receiving drive mechanism can be a cylinder, which can also be mounted on the feeding rack 24. The cylinder can be connected to the receiving plate 27 through an L-shaped connecting rod. The connecting rod is arranged on the side of the discharge bin 25 near the feeding mechanism 26. One end of the connecting rod is connected to the cylinder, and the other end of the connecting rod is connected to the center of the receiving plate 27, thereby controlling the horizontal movement of the receiving plate 27. However, in this scheme, the material will fall onto the connecting rod.

[0038] In some embodiments, the height of the discharge port 251 is equal to the sum of the lengths of the plurality of receiving plates 27, such that the discharge port 251 can be closed when the plurality of receiving plates 27 are rotated to the clearance position.

[0039] like Figure 2 As shown, when the receiving plate 27 rotates to the clearance position, it can connect with the receiving plate 27 above it, thereby achieving the closure of the discharge port 251. The closure of the discharge port 251 does not need to be completely sealed; it is only necessary to ensure that most of the material falling into the discharge bin 25 will not splash out of the discharge bin 25. In addition, a sealing colloid can be provided on the edge of the receiving plate 27. The receiving plate 27 contacts the inner wall of the discharge bin 25 and the adjacent receiving plate 27 through the sealing colloid, thereby improving the sealing performance.

[0040] In addition, multiple discharge ports can be set at intervals, with each discharge port corresponding to a receiving plate, and the height of the discharge port is equal to the length of the receiving plate.

[0041] This utility model also provides an organic waste feeding system, including the aforementioned multi-layer organic waste feeder, and further including a track 5 and a push-pull mechanism, as shown below. Figure 5 As shown, the multi-layer conversion frame 1 is arranged on the track 5, which is parallel to the conveying direction of the feeding conveyor 261. The push-pull mechanism is used to control the multi-layer conversion frame 1 to move closer to or further away from the feeding conveyor 261, so that the material on the feeding conveyor 261 falls evenly onto the conversion box 11.

[0042] Understandable, Figure 1 In the state shown, the material can only be conveyed to one end of the conversion box 11 and accumulate. Therefore, it is necessary to move the conversion box 11 during the conveying process so that the material falls evenly into the conversion box 11. By setting the track 5 and the push-pull mechanism, the material in the conversion box 11 can be evenly spread.

[0043] like Figure 5 As shown, a placement platform 6 is provided on the track 5, and rollers 61 are provided on the bottom of the placement platform 6, so that the placement platform 6 can move on the track 5. Figure 6 As shown, the rollers 61 are secured to both sides of the track 5, making it difficult for them to derail. The multi-layer conversion frame 1 can be installed on the placement platform 6. The multi-layer conversion frame 1 and the placement platform 6 can be fixedly connected by bolts or snap-fit. For example, a connecting plate is integrally provided at the bottom of the multi-layer conversion frame 1, and bolt holes are provided on the placement platform 6. The multi-layer conversion frame 1 can be fixed by fixing the connecting plate to the placement platform 6. Alternatively, a fixing hole is provided on the bottom side of the multi-layer conversion frame 1, and multiple snap-fit ​​holes are provided on the placement platform 6. An elastic locking pin is provided on the side of the placement platform 6. After the bottom of the multi-layer conversion frame 1 is inserted into the snap-fit ​​hole, one end of the elastic locking pin extends into the snap-fit ​​hole and is inserted into the fixing hole of the multi-layer conversion frame 1, thereby fixing the multi-layer conversion frame 1. When it is necessary to remove the multi-layer conversion frame 1, the elastic locking pin is pulled, so that one end of the elastic locking pin is pulled out from the fixing hole of the multi-layer conversion frame 1.

[0044] The push-pull mechanism can use the principle of gear and rack to control the movement of the placement platform 6. For example, the push-pull mechanism includes a geared motor, which is arranged below the placement platform 6. The output end of the geared motor is fixedly connected to a gear. A rack is set at the bottom of the placement platform 6. The rack meshes with the gear to generate linear displacement. The movement should be slow to ensure the smooth movement of the multi-layer conversion frame 1.

[0045] The working principle of this organic waste feeding system is as follows:

[0046] The pre-treated material is conveyed to the multi-layer feeder 2. Insect seedlings are added simultaneously as the material is conveyed to the multi-layer feeder 2. The multi-layer feeder 2 then conveys the material into each conversion box 11 of the multi-layer conversion rack 1. Specifically, this includes:

[0047] The lifting mechanism 23 continuously lifts the material to the top of the discharge bin 25. The feeding controller controls a certain receiving drive mechanism, so that the receiving plate 27 corresponding to the receiving drive mechanism rotates to the receiving position. The receiving plates 27 above the receiving plate 27 corresponding to the receiving drive mechanism are all in the avoidance position.

[0048] Feeding conveyor 261 conveys materials to the corresponding conversion box 11;

[0049] The push-pull mechanism controls the multi-layer conversion frame 1 to move closer to or further away from the feeding conveyor 261, so that the material on the feeding conveyor 261 falls evenly onto the conversion box 11, thus completing the feeding of the conversion box 11.

[0050] Repeat the above steps until all conversion boxes 11 have been filled.

[0051] It should be noted that material should generally be added starting from the lowest conversion box 11 to avoid raising the center of gravity of the bogie and affecting its stability.

[0052] Furthermore, the push-pull mechanism can be controlled by a controller, and the multi-layer feeder 2 can also automatically control the feeding time and quantity through the controller. Since the conveying speeds of the lifting mechanism 23 and the feeding conveyor 261 are known, the feeding time for each conversion box 11, i.e., the time T0 for each receiving plate 27 to be in the receiving position, can be calculated based on the conveying speed and the amount of material to be added. Specifically:

[0053] Initially, all receiving plates 27 are in the clearance position. Material is first added to the lowest conversion box 11. The controller activates the lifting device, feeding conveyor 261, and push-pull mechanism, allowing the material to fall directly to the bottom of the discharge bin 25 and slide onto the lowest feeding conveyor 261. The feeding conveyor 261 then transports the material into the lowest conversion box 11. Under the action of the push-pull mechanism, the multi-layer conversion frame 1 ensures the material falls evenly onto the conversion box 11. After time T0, the controller activates the receiving drive corresponding to the second layer (from bottom to top) feeding conveyor 261. The drive mechanism rotates the receiving plate 27 to the receiving position, and the material falls onto the receiving plate 27. It is then conveyed to the conversion box 11 of the second layer (from bottom to top) by the feeding conveyor 261 of the second layer. After time T0, the controller controls the receiving drive mechanism corresponding to the feeding conveyor 261 of the third layer (from bottom to top) to rotate the receiving plate 27 to the receiving position to feed the conversion box 11 of the third layer (from bottom to top). This process is repeated until all conversion boxes 11 are fed. The controller then controls the lifting device, feeding conveyor 261, and push-pull mechanism to close.

[0054] This utility model, through a multi-layer three-dimensional process design, realizes the feeding of multi-layer conversion rack 11, and expands insect farming from a flat pond farming mode to a three-dimensional farming mode. Compared with the flat pond farming mode, the three-dimensional farming mode saves space, is conducive to deodorization, has simple equipment functions and processes, is fully automated in the farming process, has high efficiency, low farming cost, and can be scaled up, industrialized, clean and environmentally friendly, which is conducive to industrial promotion.

[0055] This invention features a reasonable structure, convenient operation, small footprint, and low labor requirements, making it particularly suitable for large-scale factory farming. The resource utilization of organic waste and the elimination of livestock manure pollution are of great significance for protecting the ecological environment and promoting sustainable agricultural development.

[0056] The above-described embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model, and should all be included within the protection scope of this utility model.
