Abstract
Description
Technical Field
[0001] This utility model relates to the field of insect breeding technology, specifically to an insect breeding and recycling device. Background Technology
[0002] Black soldier flies are highly efficient resource insects that decompose organic waste, and their larvae can be used to produce animal protein feed. Currently, black soldier fly farming generally utilizes pulverized kitchen waste or poultry manure. During the breeding process, it is necessary to regularly clean the sand containing the larvae. Furthermore, once the larvae have grown to a certain length, they need to be separated for other uses. However, because the larvae are mixed with the sand, this process becomes difficult.
[0003] Currently, black soldier fly larvae are typically recovered manually or through vibrating sieving. This method utilizes the fact that black soldier flies are larger than the debris; by controlling the screen mesh size and using screen vibration, the black soldier flies and debris are separated. However, manual sieving is inefficient, and vibrating sieving is not effective at separating larvae from debris, while causing mechanical damage to the larvae. Utility Model Content
[0004] To overcome the above shortcomings, this utility model provides an insect breeding and recycling device.
[0005] The technical solution of this utility model is:
[0006] An insect breeding and recycling device, comprising:
[0007] The recycling bin includes a casing with a feeding hopper on one side of the top. An insect sand box is slidably installed on the bottom surface inside the casing. A screening component is located inside the casing and between the feeding hopper and the insect sand box. The screening component includes a vibration component with several layers of vibrating screens inside. The vibration component is used to drive the vibrating screens to vibrate and separate larvae and insect sand. A spraying component is located above each layer of the vibrating screens to spray atomized water to moisten the larvae and the material.
[0008] Preferably, the chassis is open at both ends, and an inspection plate is provided on the upper part of the outer side of the rear opening of the chassis. An inspection door is rotatably installed at the bottom of the inspection plate, and the inspection plate cooperates with the inspection door to close the rear opening of the chassis.

A vibration source is provided on the top of the vibration frame, and the vibration frequency of the vibration source can be adjusted between 20-50Hz.
[0010] Preferably, the vibrating screen includes a screen frame, which is fixedly installed inside the vibrating frame. The head of the screen frame is inclined downward and is provided with a discharge hopper. The discharge hopper extends from the front opening of the machine box, and the discharge direction of the discharge hoppers at different heights is different.

[0025] 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.
[0026] Example 1:
[0027] Please see Figure 1-5 The present invention will describe the above technical solution in detail through the following embodiments:
[0028] An insect breeding and recycling device, comprising:
[0029] The recycling bin 1 includes a casing 11. A feeding hopper 12 is provided on one side of the top of the casing 11. An insect sand box 17 is slidably installed on the bottom surface inside the casing 11. A screening component 2 is provided inside the casing 11 and between the feeding hopper 12 and the insect sand box 17. The screening component 2 includes a vibration component. The vibration component has two layers of vibrating screens. The vibration component is used to drive the vibrating screens to vibrate and separate larvae and insect sand. A spray component 3 is provided above each layer of vibrating screens. The spray component 3 is used to spray atomized water to moisten the larvae and materials.
[0030] The chassis 11 is fixed by steel plates using bolts and welding.
[0031] The feeding hopper 12 is welded to the iron plate on the top of the casing 11, and the bottom of the feeding hopper 12 extends downward into the interior of the casing 11.
[0032] The chassis 11 is open from front to back. A maintenance plate 13 is provided on the upper part of the outer side of the rear opening of the chassis 11. A maintenance door 14 is rotatably installed on the bottom of the maintenance plate 13. The maintenance plate 13 cooperates with the maintenance door 14 to close the rear opening of the chassis 11.
[0033] The access door 14 and the access panel 13 are connected by a hinge, allowing the access door 14 to rotate upwards to a horizontal position and maintain that position. A handle 15 is fixedly installed on the outer center of the access door 14 by screws, which facilitates the operator to drive the access door 14 to rotate.
[0034] The bottom surface inside the chassis 11 is symmetrically fixed with slide rails 16 by bolts. The insect sand box 17 is slidably installed between the slide rails 16. The slide rails 16 are used to limit the movement direction of the insect sand box 17 and reduce the friction when the waste insect sand 17 moves.
[0035] The insect sand box 17 can only be pulled out from the rear of the chassis 11. The insect sand box 17 is made of light-transmitting plastic.
[0036] The vibration assembly includes four legs 21, which are fixedly installed on both sides inside the housing 11 by bolts. A vibration frame 23 is installed above the legs 21 by elastic elements 22. A vibration source 24 is provided on the top of the vibration frame 23. The vibration frequency of the vibration source 24 can be adjusted between 20-50Hz.
[0037] The elastic element 22 is a helical spring, which allows the vibrating frame 23 to move relatively limitedly relative to the support leg 21.
[0038] The vibration source 24 adopts a known vibration motor. When the vibration source 24 is working, it can generate periodic vibration, thereby driving the vibration frame 23 to vibrate periodically.
[0039] The vibration frequency of vibration source 24 is selected according to the larval growth stage.
[0040] The vibrating screen includes a screen frame 25, which is fixedly installed inside the vibrating frame 23 by bolts. The head of the screen frame 25 is inclined downward and a discharge hopper 28 is fixedly installed by bolts. The discharge hopper 28 extends out from the front opening of the machine box 11. The discharge direction of the discharge hopper 28 is different for different heights.
[0041] The vibration of the vibrating frame 23 can drive the screen frame 25 to vibrate.
[0042] The discharge hopper 28 has different discharge directions, which facilitates the collection of the screened materials.
[0043] The screen frame 25 is vertically continuous, and a sliding groove 26 is provided on the bottom inner side of the screen frame 25 extending to the rear end. A screen 27 is slidably installed in the sliding groove 26. The screen 27 is made of flexible material.
[0044] The screen 27 is made of polyurethane. The screen 27 is inserted into the screen frame 25 through the slide 26, and the screen 27 and the slide 26 are fixed by tensioning.
[0045] The mesh size of the screen 27 varies with different heights, and the mesh size of the screen 27 gradually decreases from high to low.
[0046] The upper screen 27 is used for coarse screening, with a mesh size of 4-6mm, to remove large particles of waste from the waste residue.
[0047] The lower screen 27 is used for fine sieving, with an aperture of 1.5-2mm. The appropriate size is selected based on the larvae's size. It is used to separate waste and larvae.
[0048] The selected larvae will be discharged from the lower discharge hopper 28, and the waste will fall into the insect sand box 17.
[0049] Since the rear of chassis 11 is closed, only the front opening allows light to pass through, and light will enter chassis 11 from the front.
[0050] If any larvae accidentally fall into the waste inside the insect sand box 17, they will gather in the rear half of the insect sand box 17 due to their aversion to light.
[0051] During the screening process, the larvae can be observed in the insect sand box 17 by opening the inspection door 14, and the larvae in the insect sand box 17 can be taken out through the opened inspection door 14.
[0052] The spray assembly 3 includes several spray pipes 31, which pass through the housing 11 from left to right. Each spray pipe 31 is equipped with several atomizing nozzles 32, which are tilted downwards and aligned with the vibrating screen. Each spray pipe 31 is equipped with a control valve 33 at its end.
[0053] After water is introduced into the spray pipe 31, it can be sprayed out from the atomizing nozzle 32. The atomizing nozzle 32 is used to atomize the water to wet the waste residue, larvae, and screen 27. This facilitates the separation of larvae and waste residue, increases the lubricity of the screen 27, and reduces mechanical damage to the larvae.
[0054] The control valve 33 is used to control the water flow rate inside the spray pipe 31, thereby controlling the amount of water sprayed and preventing the waste residue from becoming too wet.
[0055] The control valve 33 can be a solenoid valve or a manual valve.
[0056] Working principle:
[0057] The larvae and waste residue are fed into the feeding hopper 12.
[0058] The vibration source 24 is controlled to operate, driving the vibration frame 23 to vibrate periodically, which in turn drives the screen frame 25 and the screen 27 to vibrate, thereby causing the waste residue and larvae to vibrate. Thus, the screen 27 is used to separate the waste residue and larvae.
[0059] The vibration frequency of vibration source 24 is adjusted according to the growth stage of the larvae.
[0060] The upper screen 27 separates larger particles, while the lower screen 27 separates larvae and insect sand. The larvae are discharged from the discharge hopper 28, and workers can collect them using basins or rearing boxes.
[0061] The insect sand will fall into the insect sand box 17.
[0062] During the screening process, the drive control valve 33 is opened, and the spray assembly 3 sprays atomized water to wet the insect sand, larvae, and screen 27. This facilitates the separation of larvae and insect sand, increases the lubricity of the screen 27, and reduces mechanical damage to the larvae.
[0063] If the insect sand that falls into the insect box 17 contains larvae, they will gather towards the rear due to their aversion to light.
[0064] The inspection door 14 can be opened periodically to check whether there are larvae in the insect sand box 17. If so, the larvae can be removed through the opened inspection door 14.
[0065] If there is too much waste in the insect sand box 17, the insect sand box 17 can be pulled out through the inspection door 14 and replaced with a new insect sand box 17.
[0066] When the screen 27 needs to be replaced, the inspection plate 13 can be opened, the old screen 27 can be pulled out from the slide 26, and a new one can be installed.
[0067] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments.
