Description

Technical Field

[0001] The present application relates to the technical field of insect breeding equipment, and in particular to a lightweight and simplified laminated insect breeding equipment. Background Art

[0002] The black soldier fly, also known as the bright-spotted flathorn soldier fly, is a saprophytic insect of the family Smilocypridae in the order Diptera. Its larvae consume a wide variety of decaying organic matter, with a high appetite. They can rapidly convert organic waste into their own components, increasing their weight by a thousandfold. Furthermore, the products of black soldier fly farming have high economic value. Fully grown larvae can be used as animal feed or in biodiesel production, and the residue left after processing organic waste can be used as organic fertilizer. Using black soldier fly larvae to convert organic waste into animal protein feed has become a hotly anticipated emerging technology.

[0003] Currently, the bioremediation of food waste using black soldier flies is primarily achieved through extensive ground farming or stacked box farming. Ground farming occupies a large area and relies on manual sorting and sorting, which increases labor costs and reduces efficiency. While stacked box farming reduces floor space through stacked farming equipment, it still requires additional external auxiliary equipment, increasing operating costs. Overall, existing farming methods have high labor costs, hindering economic efficiency and precise control of the farming process.

[0004] Automated farming is a new trend in the aquaculture sector. Fully automated farming can reduce labor costs and improve conversion efficiency. However, existing automated farming systems mostly use robotic discharging devices, which offer a high degree of automation but are also complex and difficult to maintain. For example, Chinese utility model publication No. CN 209950163 U designs a fully automated three-dimensional farming device for black soldier flies. Stacked tray farming equipment enables automated farming and boasts a relatively high level of automation maturity, but the equipment's structure is complex, resulting in a high failure rate during operation. It also suffers from high equipment investment, high operating costs, and a low input-output ratio. Chinese patent publication No. CN 213819441 U designs a containerized automated farming system for black soldier flies. Its modular, skid-mountable, and integrated design facilitates the widespread use of automated farming systems. However, this equipment is expensive and prone to failure, and a single component failure can easily paralyze the farming system. Publication No. CN 210157873 U also designs a semi-automatic farming rack for black soldier flies. By stacking the cages in two sections, the overall volume and floor space are significantly reduced, increasing the production volume and facilitating unloading. However, manually operating latches to dump and reset the cages is time-consuming and labor-intensive, and unloading from both sides prevents the use of a shared discharge conveyor, resulting in low space utilization.

[0005] Generally speaking, existing automated aquaculture equipment includes containerized, warehouse-based, assembly-line, and tunnel-based systems. However, these systems often suffer from complex structures, high failure rates, high equipment investment, high operating costs, and low yields, severely hindering the industrialization of organic waste-to-black soldier fly conversion technology. Therefore, the design and development of lightweight, simplified black soldier fly aquaculture equipment that can improve organic waste processing capacity per unit area has become a pressing technical challenge in black soldier fly aquaculture. Summary of the Invention

[0006] In response to the above problems, the present application provides a lightweight and simplified laminated insect breeding equipment to simplify the breeding equipment, improve breeding efficiency, and reduce manual labor intensity.

[0007] To achieve the above objectives, this application is implemented through the following technical solutions:

[0008] The present application provides a light and simplified laminated insect breeding equipment, including a brake motor, a breeding frame, a breeding box frame, a frame plate structure, a linkage rod, a limit rod (including a first limit rod and a second limit rod) and a traction rope; the breeding frame is composed of a first column, a second column frame, a third column frame and a plurality of side beams arranged between them, the first column frame includes a first left column and a first right column, the first left column and the first right column are connected as a whole by a first upper beam arranged on their tops and a first lower beam arranged on their bottoms; a first left oblique column and a first right oblique column are connected between the first upper beam and the first lower beam; two first limit rods are provided in the middle section of the first upper beam through a hinge; the first limit rod is a short rod structure, and the short rod One end is provided with a hinge hole, and the other end is provided with a straight slot; one end of the first limiting rod is hinged to the middle part of the first upper beam through the hinge hole, and the other end is connected to the second hinge shaft at the top of the uppermost breeding box rack through the straight slot; the third column rack is composed of the third left column, the third right column, the third upper beam, the third lower beam, the third left oblique column, the third right oblique column and two third limiting rods, and its structure is exactly the same as that of the first column rack; the second column rack is composed of the second left column, the second right column, the second upper beam arranged at the top of the second left column and the second right column, and the second lower beam arranged at the bottom of the second left column and the second right column, wherein the second lower beam is arranged above all breeding box racks, and the second column rack is not provided with a limiting rod.

[0009] The first column frame, the second column frame and the third column frame are connected as a whole by a number of side beams that are evenly spaced from top to bottom on both sides, and together form a breeding frame body; these side beams are fixedly connected to the left columns (i.e., the first left column, the second left column and the third left column) and the right columns (i.e., the first right column, the second right column and the third right column) of the three column frames through corresponding first bolts.

[0010] Two discharging devices with identical structures are symmetrically arranged on the left and right sides of the breeding frame. Each discharging device includes a brake motor, a rotating shaft, a breeding box frame, a linkage device and other structures. The following takes the discharging device on one side as an example to illustrate its structure: the brake motor is fixedly connected to the end of the second upper beam through the motor support plate and the second bolt, the bottom of the motor support plate is fixedly connected to the second lower beam through two inclined columns, the rotating shaft is set on the top of the first upper beam, the second upper beam and the third upper beam, and is connected to the three upper beams in rotation through corresponding bearings and bearing seats; a gear is fixedly provided in the middle section of the rotating shaft, and the brake motor drives the gear on the corresponding side to rotate through a chain, thereby driving the rotating shaft to rotate; a traction rope is provided at both ends of the rotating shaft; one end of the traction rope is connected to the rotating shaft, and the other end is connected to the frame structure.

[0011] Several breeding box racks are evenly spaced from top to bottom and installed above the side beams of the breeding frame body. After the breeding box rack is installed, the end close to the two side columns (left column or right column) is the outer side, and the end farther away from the two side columns (left column or right column) is the inner side. The breeding box rack is a rectangular frame structure, and its bottom, front end, rear end and outer side walls are provided with several side beams. The outer end of the bottom of each breeding box rack is provided with a first hinge axis, and the inner end of the top of the breeding box rack is provided with a second hinge axis. The breeding box rack is hinged to the corresponding side beam on the same side through the first hinge axis and can rotate around the corresponding side beam; the bottom of the inner side wall of the breeding box rack is hinged to the openable and closable frame plate structure. The frame plate structure is a trapezoidal frame structure, and its shape matches the shape of the side wall of the breeding box rack. One end of the frame plate structure is connected to the bottom of the breeding box rack by a hinge, and the other end is hinged to the second linkage rod. In addition, the end of the frame plate structure arranged at the top is also hinged to the traction rope on the corresponding side;

[0012] The front and rear ends of the breeding box rack are provided with linkage devices of the same structure. The following takes the linkage device at one end as an example to illustrate its structure: the linkage device includes a first limiting rod, a first linkage rod, a second linkage rod, a frame plate structure, and a traction rope. A first linkage rod is provided between the inner top ends of several breeding box racks from top to bottom on the same side. The first linkage rod is hinged to the second hinge shaft on the inner side of these breeding box racks. The second hinge shaft of the breeding box rack at the top is hinged to the straight slots of the first linkage rod and the first limiting rod at the same time. When the breeding frame rotates, the second hinge shaft moves relatively along the straight slot, thereby limiting the rotation angle of the breeding frame. A second linkage rod is also hinged between the ends of the frame plate structures from top to bottom on the same side. The end of the frame plate structure at the top is hinged to the traction rope on the corresponding side at the same time.

[0013] In practice, the two rows of black soldier fly breeding boxes between the left and right columns are each multi-layered. The number of these layers depends on the height of the aquaculture equipment and the environmental control requirements. Furthermore, the left and right columns can be positioned closer to the centerline of the breeding boxes to support the load of the wide breeding boxes and reduce the required traction rope tension.

[0014] In a specific implementation, a conveyor belt is further provided under the breeding rack body, and the output materials dropped from the breeding box racks on the left and right sides can be transported by the conveyor belt.

[0015] Compared with the existing technology, the breeding equipment provided by this application has the following beneficial effects:

[0016] (1) Each layer of the stacked breeding rack of this equipment is provided with two breeding box racks on the left and right, and the breeding box racks on each layer are set at the same distance, which realizes the light and simplified design of the feeding equipment, and at the same time increases the breeding area and improves the breeding efficiency; the breeding box racks on the same side are linked by a linkage rod, and when discharging, the breeding box racks on the same side can discharge materials at the same time; compared with the existing stacked breeding equipment discharging mode on both sides, which reduces the utilization rate of breeding land and affects the design of the working road of the feeding vehicle, this application realizes for the first time that the breeding box racks on both sides rotate inward, which can realize the centralized processing of materials, and the breeding box racks on both sides share a conveyor belt, which reduces equipment costs and improves the utilization rate of breeding space.

[0017] (2) The outer sides of the breeding box racks on both sides of this equipment are hinged on the side crossbeams. The inner ends of the top breeding box racks are connected together by a traction rope and a rotating shaft. The breeding box racks on the same side are connected together by a first linkage rod and a second linkage rod. When breeding black soldier flies, the breeding box racks are placed horizontally. After the breeding is completed, the rotating shaft can be driven by a brake motor to slowly lower the inner end of the breeding box rack to discharge the material, saving time and manpower. After the limit rod limits the breeding box rack, the shelf plate at the inner end of the breeding box rack slowly opens, and the material falls onto the discharge conveyor belt set under the breeding rack body. After the discharge is completed, the breeding box rack is reset by the brake motor and the next round of breeding is carried out. One end of the breeding box rack is hinged on the breeding rack body and provides power to the other end. The horizontal and tilting of the breeding box rack are achieved by rotating around one end. Compared with the existing fully automatic breeding device, the structure is relatively simple, the failure rate is low, and the parts are easy to replace.

[0018] (3) The breeding box racks on both sides of this equipment are controlled by two brake motors respectively. During the discharging process, one side can be discharged first, and after the breeding rack is reset, the other side can be discharged. This can prevent the two sides from interfering with each other when discharging at the same time, and also avoids increasing the structure of the breeding rack to prevent mutual interference.

They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore should not be understood as limiting the present invention. In addition, the terms "first", "second", etc. are only used to distinguish the description and should not be understood as indicating or implying relative importance.

[0028] Example 1

[0029] A light and simplified laminated insect breeding equipment includes a brake motor 1, a breeding frame 2, a breeding box frame 3 and a retractable frame plate structure 4, a first linkage rod 51, a second linkage rod 52, a first limit rod 6 and a traction rope 7.

[0030] like Figure 1 、 Figure 2 As shown, the breeding frame 2 is composed of three column frames (respectively, the first column frame 21, the second column frame 22 and the third column frame 23) and a number of side beams 24 arranged between the three column frames. The first column frame 21 includes a first left column 211 and a first right column 212. The first left column 211 and the first right column 212 form a frame structure connected as one by the first upper beam 213 set on their top and the first lower beam 214 set on their bottom. The first left oblique column 215 and the first right oblique column 216 are connected between the first upper beam 213 and the first lower beam 214. The middle section of the first upper beam 213 is provided with two first limiting rods 6 through a hinge, as shown Figure 5 As shown, the first limiting rods 6 are all short rods with a hinge hole 61 at one end and a straight notch 62 at the other end. One end of the first limiting rod 6 is hinged to the middle portion of the first upper crossbeam 213 via the hinge hole 61, and the other end is connected to the second hinge axis 32 of the left and right top-mounted breeding box racks 3 via the straight notch 62. The third column rack 23 consists of a third left column, a third right column, a third upper crossbeam, a third lower crossbeam, a third left oblique column, a third right oblique column, and two third limiting rods. Its structure is identical to that of the first column rack 21. The second column rack 22 consists of a second left column, a second right column, a second upper crossbeam 223 located at the tops of the second left and second right columns, and a second lower crossbeam 224 located at the bottoms of the second left and second right columns. The second lower crossbeam 224 is located above all breeding box racks 3. The second column rack 22 does not have a limiting rod.

[0031] like Figure 3As shown, the three column frames (i.e., the first column frame 21, the second column frame 22, and the third column frame 23) are connected together by a number of side crossbeams 24 evenly spaced from top to bottom on both sides, together forming the breeding frame body 2. These side crossbeams 24 are fixedly connected to the left columns (i.e., the first left column, the second left column, and the third left column) and the right columns (i.e., the first right column, the second right column, and the third right column) of the three column frames by corresponding first bolts 11.

[0032] Two discharging devices with identical structures are symmetrically arranged inside the breeding frame 2. Each discharging device includes a brake motor 1, a rotating shaft 8, a breeding box frame 3, a linkage device and other structures. The following takes the discharging device on one side as an example to illustrate its structure: the brake motor 1 is fixedly connected to the end of the second upper crossbeam 223 through the motor support plate 15 and the second bolt 14 (welded in this embodiment), and the bottom of the motor support plate 15 is fixedly connected to the second lower crossbeam 224 through two inclined columns 16 (welded in this embodiment). The rotating shaft 8 is set at the top of the three upper crossbeams (i.e., the first upper crossbeam 213, the second upper crossbeam 223 and the third upper crossbeam), and is rotatably connected to these three upper crossbeams through corresponding bearings 12 and bearing seats 13; a gear 9 is fixedly provided in the middle section of the rotating shaft 8, and the brake motor 1 drives the gear 9 on the corresponding side to rotate through the chain 10, thereby driving the rotating shaft 8 to rotate. A traction rope 7 is provided at both ends of the rotating shaft 8; one end of the traction rope 7 is connected to the rotating shaft, and the other end is connected to the frame structure 4.

[0033] Several breeding box racks 3 are evenly spaced from top to bottom and installed above the side beam 24 of the breeding frame body 2. After the breeding box rack 3 is installed, the end close to the two side columns (left column or right column) is the outer side, and the end farther from the two side columns (left column or right column) is the inner side. Figure 4 As shown, the breeding box frame 3 is a rectangular parallelepiped frame structure, with several side beams 33 installed at the bottom, front, rear, and outer sidewalls. (During breeding, a plastic sheet or other supporting structure is laid inside the breeding box frame 3, where the black soldier fly larvae live.) The bottom of the inner sidewall is hingedly connected to a retractable frame plate structure 4. The frame plate structure 4 is a trapezoidal frame structure, its shape matching the shape of the breeding box frame sidewalls. One end of the frame plate structure 4 is connected to the bottom of the breeding box frame 3 via a hinge, and is opened and closed by the traction rope 7, the first linkage rod 51, and the second linkage rod 52. The other end of the frame plate structure 4 is connected to the second linkage rod 52. The outer end of the bottom of each breeding box frame 3 is provided with a first hinge shaft 31, and the inner end of the top is provided with a second hinge shaft 32. The first hinge shaft 31 and the second hinge shaft 32 are arranged diagonally; the breeding box frame 3 is hinged to the corresponding side beam 24 on the same side through the first hinge shaft 31, and can rotate around the corresponding side beam 24 under the drive of the traction rope 7 / the first linkage rod 51 / the second linkage rod 52.

[0034] The front and rear ends of the breeding box rack 3 are provided with linkage devices of the same structure. The following takes the linkage device at one end as an example to illustrate its structure: the linkage device includes a first limiting rod 6, a first linkage rod 51, a second linkage rod 52, a frame structure 4, and a traction rope 7. A first linkage rod 51 is provided between the inner top ends of several breeding box racks 3 from top to bottom on the same side. The first linkage rod 51 is hinged to the inner top ends of these breeding box racks 3 through a second hinge shaft 32; Figure 6 As shown, the top inner side of the topmost breeding box frame 3 is also hinged to the straight notch 62 of the first limiting rod 6 via the second hinge axis 32. The straight notch 62 of the first limiting rod 6 can move relative to the second hinge axis 32 when the breeding frame body 3 rotates, thereby limiting the rotation angle of the breeding frame body 3. A second linkage rod 52 is also provided between the ends of the top-down shelf structure 4 on the same side. The second linkage rod 52 is hinged to these shelf structure 4. The end of the topmost shelf structure 4 is also hinged to the traction rope 7 on the corresponding side and is connected to the end of the rotating shaft 8 through the traction rope 7.

[0035] The farming boxes 3 on the same side are connected by a frame structure 4 hinged at the front and rear ends of each frame and linkage rods 5 (including a first linkage rod 51 and a second linkage rod 52). The brake motor 1 rotates the shaft 8 via a gear 9, thereby extending and lowering the traction rope 7. As the traction rope 7 descends, the farming boxes 3 rotate around the side crossbeam 24 under the action of gravity, lowering the inside of the farming boxes 3 and driving the other farming boxes 3 on the same side in tandem via the linkage rods 5 (the first linkage rod 51 and the second linkage rod 52). When the hinge axis at the top inner side of the topmost farming box 3 reaches the bottom end of the straight slot of the stop rod 6 due to the rotation of the farming box 3 to discharge the material, the farming box 3 cannot rotate further, thus limiting its position. The frame structure 4 then rotates around the inside of the bottom of the farming box 3 to open and discharge the material. The material in the breeding box rack 3 falls onto the discharging conveyor 17 arranged under the breeding rack body 2. The breeding box racks on the same side can discharge the material at the same time, and the breeding box racks on both sides share a conveyor belt when discharging the material. After the discharging is completed, the traction rope 7 is lifted by the brake motor 1 to drive the linkage device to rotate, reset the breeding box rack 3, and carry out the next round of breeding.

[0036] This equipment realizes a light and simplified design of feeding equipment. The two rows of black soldier fly breeding box racks between the left column and the right column are both provided with multiple layers. The number of the multi-layer breeding box racks can be determined by the height of the facilities installed with the breeding equipment and the limited requirements of the breeding environment control, thereby increasing the breeding area and improving the breeding efficiency. The breeding box racks on both sides are respectively controlled by two brake motors. During the discharging process, one side can be discharged first, and after the breeding frame is reset, the other side can be discharged. This can save time and manpower, prevent mutual interference when discharging on both sides at the same time, and avoid increasing the structure of the breeding frame to prevent mutual interference. The breeding box racks on both sides share a discharging conveyor belt when discharging, thereby reducing equipment costs.

[0037] The above is a preferred embodiment of the application device, but the embodiment of the application is not limited to the above content. Any other changes, modifications, substitutions, combinations, and simplifications that do not deviate from the spirit and principles of the application device should be considered equivalent replacement methods and are included in the scope of protection of this application.
