Description

Technical Field

[0001] The utility model relates to the technical field of black soldier flies breeding, in particular to an optical screening machine for black soldier flies. Background Art

[0002] Black soldier fly, a saprophytic insect of the family Solenopsis, can feed on livestock and poultry manure and domestic garbage to produce high-value animal protein feed. Due to its rapid reproduction, large biomass, wide diet, high absorption and conversion rate, easy management, low feeding cost, and good palatability for animals, it can be utilized as a resource. It is currently widely used in the treatment of waste such as chicken manure, pig manure, and kitchen waste.

[0003] After breeding, black soldier flies need to be screened out in the feces. Traditional screening machines generally place feces containing black soldier flies on a screen and irradiate the feces containing black soldier flies with fluorescent lamps, LED lamps or natural light. The black soldier flies will be stimulated to crawl downward, and some black soldier flies will break away from the feces and drill through the mesh of the screen and fall out. Some black soldier flies will hide inside the feces because the screen is in a suspended state and is unsafe. This results in the traditional screening machine requiring multiple screenings to screen out all the black soldier flies, and the screening efficiency is low. Utility Model Content

[0034] Such as Figure 1 andFigure 2 As shown in the figure, the utility model provides a black soldier fly optical screening machine, which includes a main body frame 1. A loop drive device 3 is arranged inside the main body frame 1. The loop drive device 3 is sequentially connected with a plurality of feeding turnover plates 4 in the length direction thereof. The loop drive device 3 can drive the feeding turnover plates 4 to rotate along a loop. A screen mesh 5 for placing materials is laid on the outer surface of the feeding turnover plates 4. A rake tooth feeding box 2 is arranged above the main body frame 1. The rake tooth feeding box 2 can lay the materials on the screen mesh 5. An irradiation lamp group 6 is arranged above the screen mesh 5 of the main body frame 1. The irradiation lamp group 6 includes a plurality of LED lamps. The LED lamps are arranged at intervals in the length direction of the main body frame 1, mainly providing a lighting effect. Since black soldier flies have a light avoidance property, under the stimulation of the irradiation lamp group 6, the black soldier flies on the screen mesh 5 will drill towards the bottom of the feces. At the same time, a plurality of screen holes are evenly arranged on the screen mesh 5. The black soldier flies in the materials can drill through the screen holes on the screen mesh 5 and get onto the feeding turnover plates 4. A plurality of brackets 7 are arranged at intervals in the length direction below the upper feeding turnover plate 4. When the loop drive device 3 drives the feeding turnover plate 4 to move to the position where there is a bracket 7, the feeding turnover plate 4 is in a horizontal transverse state. When the feeding turnover plate 4 moves to the position where there is no bracket 7, the feeding turnover plate 4 will turn downwards, so as to pour the black soldier flies downwards. The remaining feces on the screen mesh 5 can be collected at one end of the main body frame 1 through an external conveyor belt or a receiving bucket, etc.

[0035] The black soldier fly optical screening machine of the utility model adopts the structural design of the feeding turnover plate 4. The feeding turnover plate 4 can provide support for the black soldier flies and provide a safe environment for them, so that the black soldier flies can break away from the feces and drill through the screen holes on the screen mesh 5 and enter the feeding turnover plate 4, effectively solving the problem that black soldier flies hide inside the feces and improving the screening efficiency of black soldier flies.

[0036] As Figure 3 shown, in order to facilitate the collection of black soldier flies, a first feeding plate 8 is arranged below the upper feeding turnover plate 4 for receiving the fallen black soldier flies. At the same time, since there will still be a small amount of feces sticking to the screen mesh 5 after the feces are collected at one end of the loop drive device 3, a second feeding plate 9 is arranged below the lower feeding turnover plate 4 in this embodiment for receiving the remaining feces sticking to the screen mesh 5.

[0037] It should be noted that the upper feeding turnover plate 4 described in this embodiment refers to the feeding turnover plate 4 located above the loop drive device 3, and the lower feeding turnover plate 4 refers to the feeding turnover plate 4 located below the loop drive device 3.

[0038] Preferably, the first feed plate 8 and the second feed plate 9 of the present embodiment are both arranged with one side tilted downward, and a first feed trough 10 and a second feed trough 11 are arranged at intervals on one side of the main frame 1. The first feed trough 10 is located on the side of the first feed plate 8 tilted downward, and the black soldier flies on the first feed plate 8 will eventually gather in the first feed trough 10. The second feed trough 11 is located on the side of the second feed plate 9 tilted downward, and the remaining feces on the second feed plate 9 will gather in the second feed trough 11 for collection and treatment.

When the first driving motor 34 is started, the sprocket shaft 31 will drive the material receiving flap 4 to move along the circular trajectory through the first chain 32. Since the bracket 7 is arranged at intervals, the material receiving flap 4 is initially located on the bracket 7 and is in a horizontal horizontal state. The black soldier flies on the screen 5 will drill through the screen 5 and enter the material receiving flap 4. When the material receiving flap 4 moves to a position where there is no bracket 7, the material receiving flap 4 will flip downward, so that the black soldier flies fall onto the first unloading plate 8.

[0040] like Figure 8 and Figure 9 As shown, the rake-toothed material box 2 of the present embodiment specifically includes a box body 21 for placing materials, a material hopper 22 is arranged inside the box body 21 for guiding the material to be discharged; two material discharge rollers 23 are arranged below the material discharge hopper 22, and a plurality of stirring rods 24 are arranged at intervals along the length direction of the material discharge rollers 23, and the stirring rods 24 of the two material discharge rollers 23 are arranged in an interlaced manner, and a material discharge port is arranged at a position of the box body 21 corresponding to the material discharge roller 23, and the material discharge port is located above the screen 5, and a second driving device 25 is arranged on one side of the box body 21, and the second driving device 25 specifically includes a driving device installed in the box body.

[0041] likeFigure 4 and Figure 5 As shown, a cleaning roller brush 12 is further provided under one of the sprocket shafts 31 of the present embodiment. The cleaning roller brush 12 is transmission-connected to the sprocket shaft 31 through a third chain 13, and the cleaning roller brush 12 contacts the outer surface of the screen 5. Since part of the feces on the screen 5 will still stick to the screen 5 after the feces are discharged, the cleaning roller brush 12 is provided at one end of the screen 5 to remove the feces on the screen 5, and the second discharge plate 9 can also receive the remaining feces stuck to the screen 5.

[0042] like Figure 3 As shown, the main frame 1 of this embodiment is provided with a flat material adjustment plate 14 above the screen 5 , and a plurality of teeth are provided at one end of the flat material adjustment plate 14 close to the screen 5 . The flat material adjustment plate 14 can lay the material evenly on the screen 5 .
