Description

Technical Field

[0001] This invention relates to the field of black soldier fly farming equipment technology, and more particularly to a black soldier fly transplanting and farming device. Background Technology

[0002] Black soldier flies, saprophytic insects of the family Stray Fly, feed on livestock manure and household waste, producing high-value animal protein feed. Due to their rapid reproduction, large biomass, wide diet, high absorption and conversion rate, ease of management, low feeding costs, and good palatability, they are widely utilized as a resource. Their larvae are known as "phoenix worms," ​​making them a resource insect on par with fly larvae, mealworms, and superworms. Currently, they are widely used in the treatment of chicken manure, pig manure, and kitchen waste.

[0003] The larval culture environment (temperature, humidity, refined nutrients, etc.) is relatively demanding and generally requires separate management. After the larvae have fully developed, current technology generally uses a shovel to scoop them onto the surface of the waste to be treated. For materials with high viscosity that are prone to caking, if the black soldier flies are piled together, some of them will not be able to access or consume nutrients, which is not conducive to their growth. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a black soldier fly larvae transplanting and breeding device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A black soldier fly larvae transplanting and rearing device includes a working platform, an inclined plate fixedly connected to one side of the working platform, a groove provided on the inclined plate, a slider slidably connected in the groove, a telescopic rod fixedly connected to the upper end of the inclined plate, the telescopic end of the telescopic rod fixedly connected to the slider, the slider fixedly connected to a larva rearing box, and multiple guide plates rotatably connected to the bottom of the larva rearing box, the guide plates being driven to rotate by a driving component.

[0007] Two baffles are fixedly connected in parallel on the upper side of the work platform, and a transplant box is set between the two baffles;

[0008] Both the larval rearing box and the transplanting box have a sloping structure at one end corresponding to the inclined plate, and the larval rearing box is smaller than the inner cavity of the transplanting box.

[0009] Preferably, each guide plate includes at least two sub-plates, one sub-plate having one end fixedly connected to a rotating shaft, the rotating shaft being rotatably connected to a larva rearing box, the end of the rotating shaft extending out of the larva rearing box being fixedly connected to a first gear, and the other sub-plate having a circular shaft built into the rotating shaft and one end extending out of the rotating shaft being fixedly connected to a second gear;

[0010] The driving component includes a mounting post, in which a first toothed rod and a second toothed rod are slidably connected. The first toothed rod meshes with a first gear, and the second toothed rod meshes with a second gear. Support springs are fixedly connected between the first toothed rod and the second toothed rod and the mounting post, respectively.

[0011] A column is fixedly connected to the upper side of the work platform, and a limiting block is fixedly connected to one side of the column. The limiting block is provided with a first guide groove and a second guide groove. The first guide groove and the second guide groove have the same structure but different elevations. The first guide groove includes an inclined surface and a horizontal surface. The angle of the inclined surface is greater than the angle of the inclined plate.

[0012] A connecting rod is fixedly connected between the driving components of adjacent guide plates.

[0013] Preferably, the inclined surface is provided with multiple arc-shaped grooves at intervals.

[0014] Preferably, the horizontal surface is provided with multiple arc-shaped grooves at intervals.

[0015] Preferably, a movable plate is provided on one side of the partition plate, and an installation groove is provided on the upper side of the movable plate. Multiple partition plates are rotatably connected in the installation groove at intervals, and a damping shaft is fixedly connected to one end of the partition plate.

[0016] Preferably, a guide post is fixedly connected to one side of the partition plate, an installation cavity is provided inside one end of the movable plate, a damping shaft extends into the installation cavity and a rubber layer is provided on its outer circle, the guide post slides into the installation cavity and is fixedly connected to one end of the installation cavity with a first spring, and the guide post can be pressed against the outer circle of the damping shaft.

[0017] Preferably, the guide post is provided with a clearance groove, which is correspondingly provided with the damping shaft.

[0018] The advantages of this invention are as follows: The black soldier fly transplanting device provided by this invention uses a telescopic rod to push the larval rearing box obliquely into the transplanting box. The transplanting box is evenly filled with nutrients. The bottom of the larval rearing box rotates to open multiple rows of guide plates. The guide plates can be inserted obliquely into the nutrient material. Some larvae fall onto the surface of the nutrient material, while others enter the interior of the nutrient material. This makes it easier to place the larvae in different positions on the nutrient material, avoiding the larvae being all on the surface of the nutrient material, avoiding the larvae blocking each other, avoiding affecting the larvae's feeding, and making the growth rate of the black soldier fly relatively uniform.

[0019] This invention involves intermittent oscillation during the insertion of the nutrient plate, resulting in a gap in the insertion groove within the nutrient material that is larger than the thickness of the plate. This facilitates the implantation and burial of larvae into the loose nutrient material, allowing larvae to be released both inside and outside the nutrient material, ensuring even feeding. Furthermore, when the first toothed rod moves to the horizontal plane, it pushes the nutrient material forward to form a ridge, increasing the surface area of ​​the nutrient material and allowing larvae to have more direct contact with it.

[0024] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention 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 the present invention and are not intended to limit the present invention.

[0025] Example 1

[0026] like Figures 1 to 4 As shown, the present invention provides a black soldier fly larvae transplanting and breeding device, including a working platform 1, an inclined plate 11 fixedly connected to one side of the working platform 1, a sliding groove provided on the inclined plate 11, a slider 13 slidably connected in the sliding groove, a telescopic rod 14 fixedly connected to the upper end of the inclined plate 11, the telescopic rod 14 is a cylinder, oil cylinder, screw and slider pair in the prior art, driving the slider 13 to move linearly, the telescopic end of the telescopic rod 14 is fixedly connected to the slider 13, the slider 13 is fixedly connected to the larvae rearing box 2, the larvae rearing box 2 has a more demanding environment (temperature, humidity, fine nutrients, etc.) than the transplanting box 66, so in order to breed in large quantities, it is necessary to separate the larvae into boxes after rearing them. Multiple guide plates 3 are rotatably connected to the bottom of the larvae rearing box 2, and the guide plates 3 are driven to rotate by a driving component 4;

[0027] Two baffles 55 are fixedly connected in parallel on the upper side of the work platform 1. A transplant box 66 is set between the two baffles 55. The transplant box 66 contains crushed kitchen waste or livestock manure, etc., so as to process waste while raising black soldier flies.

[0028] Both the larval rearing box 2 and the transplanting box 66 have a sloping structure at one end corresponding to the inclined plate 11, and the larval rearing box 2 is smaller than the inner cavity of the transplanting box 66.

[0029] After the larvae rearing box 2 of this invention has cultivated larvae of a suitable size (in the prior art, larvae need to be cultivated to a certain extent before it is convenient to handle kitchen waste and animal manure), the larvae rearing box 2 is fixed to the slider 13 by bolts or electromagnet adsorption and positioning. The larvae rearing box 2 is pushed obliquely into the transplanting box 66 by the telescopic rod 14. The transplanting box 66 is filled with nutrients, which are common organic waste such as kitchen waste and animal manure. The bottom of the larvae rearing box 2 rotates to open multiple rows of guide plates 3. The guide plates 3 can be inserted obliquely into the nutrients. Some larvae fall to the surface of the nutrients, and some enter the interior of the nutrients. This makes it easier to put the larvae into different positions of the nutrients, avoids the larvae from piling up together due to partial compaction of the materials, and avoids some larvae not being able to reach the nutrients. This makes the growth rate of black soldier flies relatively uniform.

[0030] Example 2

[0031] like Figures 1 to 4 As shown, each guide plate 3 includes at least two sub-plates 31. One sub-plate 31 is fixedly connected to a rotating shaft 32 at one end. The rotating shaft 32 is rotatably connected to the larva rearing box 2. The end of the rotating shaft 32 extending out of the larva rearing box 2 is fixedly connected to a first gear 33. The circular shaft 34 of the other sub-plate 31 is built into the rotating shaft 32 and extends out of the rotating shaft 32, and is fixedly connected to a second gear 35. That is, each sub-plate 31 can change its downward rotation angle individually, so that the rotation angle of the sub-plates 31 in the same row can be adjusted to different angles. When the sub-plates 31 are inserted into the nutrient, they form a misalignment, which facilitates the dispersed rearing of larvae.

[0032] When transplanting 1000 black soldier fly larvae into multiple groups, each group containing a large number of larvae, the dividing plate 31 of this invention acts as a guide to distribute them to different parts of the nutrient supply. This way, each group contains a small number of black soldier flies, allowing each larva to quickly access and consume the nutrients. It also facilitates the larvae to burrow into the bottom of the nutrient supply, preventing the larvae from being unable to consume the nutrients due to a large number of larvae piled up in the middle, thus affecting their growth.

[0033] For ease of explanation, this invention will be explained using two separate plates 31.

[0034] The driving component 4 includes a mounting post 41, in which a first toothed rod 42 and a second toothed rod 43 are slidably connected. The first toothed rod 42 meshes with a first gear 33, and the second toothed rod 43 meshes with a second gear 35. The first toothed rod 42 and the second toothed rod 43 are respectively fixedly connected to the mounting post 41 with a support spring 44.

[0035] A column 45 is fixedly connected to the upper side of the work platform 1, and a limiting block 46 is fixedly connected to one side of the column 45. The limiting block 46 is provided with a first guide groove and a second guide groove. The first guide groove and the second guide groove have the same structure but different elevations. The first guide groove includes an inclined surface 5 and a horizontal surface 6. The angle of the inclined surface 5 is smaller than the angle of the inclined plate 11.

[0036] In this invention, the larva rearing box 2 moves downward at an angle. Since the angle of the inclined surface 5 is greater than the angle of the inclined plate 11, when the upper end of the first toothed rod 42 moves to contact the inclined surface 5, the first toothed rod 42 forms an additional downward pressure on the larva rearing box 2, so that the first toothed rod 42 pushes the first gear 33 to drive the corresponding dividing plate 31 to rotate, which facilitates the inclined insertion of the dividing plate 31 into the nutrient and the introduction of the larvae and the larvae culture medium into the transplanting box 66.

[0037] In order to achieve different rotation angles for different plates 31, the same principle is adopted. The second toothed rod 43 is pressed down more due to the influence of the second guide groove, so that the other plates 31 can rotate at a different angle through the second toothed rod 43 and the second gear 35, which facilitates the dispersion of larvae.

[0038] A connecting rod 49 is fixedly connected between the driving components 4 of adjacent guide plates 3. When one of the guide plates 3 tilts and opens as described above, the subsequent guide plates 3 open synchronously through the connecting rod 49, thereby inserting the larval colony into the nutrient surface in a staggered manner.

[0039] Example 3

[0040] like Figures 1 to 4 As shown, the inclined surface 5 is provided with a plurality of arc-shaped grooves 51 at intervals, and the horizontal surface 6 is provided with a plurality of arc-shaped grooves 61 at intervals.

[0041] In this embodiment, during the process of inserting the partition plate 31 into the evenly distributed nutrients in the transplant box 66, the upper end of the first toothed rod 42 continuously compresses and drives the corresponding partition plate 31 to rotate (i.e., the first toothed rod 42 slides on the inclined plane 5). When it encounters the arc-shaped groove 51, a certain amplitude of swing back occurs in the partition plate 31, such as... Figure 4 As shown, a similar phenomenon can occur at point A at the lower end of plate 31. Figure 4 The movement trajectory of the thick solid line, intermittently oscillating during the insertion of nutrients, makes the gap in the groove inserted into the nutrient material greater than the thickness of the dividing plate 31, which facilitates the implantation and burial of larvae into the loose nutrient material, thus allowing larvae to be released both inside and outside the nutrient material, making it easier for larvae to feed evenly; furthermore, when the first tooth rod 42 moves to the horizontal plane 6, it pushes the nutrient material forward to form a ridge, which increases the surface area of ​​the nutrient material, allowing larvae to have more direct contact with the nutrient material.

[0042] Example 4

[0043] like Figures 1 to 4As shown, a movable plate 311 is provided on one side of the partition plate 31, and an installation groove 312 is provided on the upper side of the movable plate 311. Multiple partition plates 7 are rotatably connected in the installation groove 312 at intervals, and a damping shaft 71 is fixedly connected to one end of each partition plate 7.

[0044] Furthermore, a guide post 72 is fixedly connected to one side of the partition plate 31, and an installation cavity 73 is provided inside one end of the movable plate 311. The damping shaft 71 extends into the installation cavity 73 and has a rubber layer on its outer circle. The guide post 72 slides into the installation cavity 73 and is fixedly connected to one end of the installation cavity 73 with a first spring 74. The guide post 72 can be pressed against the outer circle of the damping shaft 71.

[0045] Furthermore, the guide post 72 is provided with a relief groove 721, which is correspondingly provided with the damping shaft 71, so that the guide post 72 does not initially contact the corresponding damping shaft 71.

[0046] In this embodiment, when the partition plate 31 is rotated open, the partition plate 7 is first perpendicular to the partition plate 31, intercepting some larvae on the partition plate 31 to prevent them from all sliding onto the nutrient surface; when the moving plate 311 contacts the bottom of the transplant box 66, the moving plate 311 moves relative to the partition plate 31, and the guide column 72 rotates the partition plate 7 in a direction parallel to the moving plate 311 by actuating the damping shaft 71, so as to facilitate the separation of larvae and release them at different times;

[0047] Furthermore, the clearance groove 721 is set according to the number of subsequent partitions 7, and the length of the subsequent clearance grooves 721 increases sequentially, so that the distance that the guide post 72 needs to move to contact the corresponding damping shaft 71 in sequence increases, thereby the different partitions 7 rotate in sequence, so that the separated larvae can be released at different times, fall into different positions of the nutrients, and facilitate the growth of the larvae.

[0048] After the larvae are released and the larval rearing box 2 is retrieved, the partition 7 is manually moved to its original position.

[0049] Finally, it should be noted that elastic cloth 10 is fixedly connected between adjacent guide plates 3 and between the dividing plate 31 and the moving plate 311 to cover the gaps and prevent larvae from leaking out.

[0050] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
