Description

Technology Field

[0001] The present invention enables the efficient separation and sorting of larvae and vermicompost in black soldier fly rearing farms, and in particular, relates to a black soldier fly larvae and vermicompost sorting device applicable to mass production and smart farm environments. Background Technology

[0002] In this document, background technology related to the present invention is provided, and these do not necessarily constitute known technology.

[0003] In the natural world, numerous insects are involved in the process of animals and plants dying and returning to nature.

[0004] For example, animal excrement, carcasses, dead trees, and fallen leaves act as decomposers and are converted into food for insects before microbial decomposition occurs. Among the insects performing this role, those that bring direct cleaning effects and benefits to the environment are defined as environmental purification insects.

[0005] The use of environmental purification insects began to develop primarily in relation to the treatment of livestock manure. Examples of environmental purification insects include dung beetles capable of processing the excrement of mammals such as cows and horses, houseflies capable of processing manure and converting it into high-quality fertilizer, and American black soldier flies for food waste treatment.

[0006] In particular, the American black soldier fly, belonging to the family Stratiidae of the order Diptera, is an insect similar to a fly, but the adult does not cause any harm to humans. Once it becomes an adult, its mouthparts degenerate, so it feeds only on dew and does not regurgitate after feeding, so it does not transmit diseases and rarely invades human settlements. Furthermore, if about 5,000 black soldier fly larvae are introduced into 10 kg of food waste, 80% of the food waste is decomposed within 3 to 5 days, allowing it to be recycled into resources such as compost, and the larvae and pupae can be utilized as animal feed, making it a very useful insect.

[0007] With the advantages and characteristics of black soldier flies, the development and dissemination of mass breeding and rearing technologies are increasing to enable the eco-friendly processing of food waste produced in large quantities in metropolitan areas and other major cities.

[0008] Meanwhile, since American black soldier flies are reared in a rearing box mixed with vermicompost and organic waste provided as feed, the separation and sorting of larvae, vermicompost, and organic waste are essential during larval production.

[0009] However, because the shape and properties of the vermicompost vary depending on the type of feed or rearing method, it was difficult to effectively separate larvae and vermicompost in all rearing environments using conventional sorting devices with a single structure.

[0010] Furthermore, since black soldier flies are produced in large quantities, the capacity of harvesting and sorting equipment must inevitably be large; however, conventional sorting devices were not optimized for such large-scale production environments, resulting in a problem of reduced efficiency.

[0011] Furthermore, the mesh nets, which are the core of the sorting process, are expensive because they must be specially custom-made, and farmers faced the burden of having to keep spare nets because they could not repair them themselves if damaged. Prior art literature

FIG. 2 is a schematic drawing showing the upper and lower screen members illustrated in FIG. 1. FIG. 3 is an enlarged cross-sectional view drawn along line AA of FIG. 2. FIG. 4 is an enlarged view of one of the pivot members shown in FIG. 1, wherein FIG. 4 (A) shows the side view and FIG. 4 (B) shows the front view. Specific details for implementing the invention

[0029] Hereinafter, an embodiment of the black soldier fly larva and vermicompost sorting device according to the present invention will be described in detail with reference to the drawings.

[0030] FIGS. 1 to 4 are schematic drawings illustrating a black soldier fly larva and frass sorting device according to the present invention.

[0031] Referring to FIGS. 1 to 4, the black soldier fly larva and worm casting device (100) according to the present invention comprises a supply unit (120) that supplies a mixture of black soldier fly larvae and worm casting, a separation and sorting unit (130) that separates and sorts black soldier fly larvae and worm casting from the mixture supplied from the supply unit (120), and a frame unit (110) that supports the supply unit (120) and the separation and sorting unit (130).

[0032] First, the frame portion (110) includes a main frame (112) and a sub-frame (114) formed integrally on the upper end of the main frame (112).

[0033] The main frame (112) is supported by a separation sorting unit (130), and the sub-frame (114) is supported by a supply unit (120).

[0034] These main frame (112) and sub frame (114) are formed from a corrosion-resistant material (e.g., stainless steel, aluminum, etc.) in consideration of the characteristics of the black soldier fly rearing environment, and are formed in a rigid frame shape to resist physical forces generated during operation, especially bending loads and torsional loads.

[0035] Meanwhile, casters (116) are installed at the bottom of the main frame (112) for ease of movement.

[0036] And in the subframe (114), a zigzag chute (118) is formed to guide the mixture flowing out from the automatic control valve (122) of the supply unit (120) to the upper screen member (132a) of the separation and sorting unit (130).

[0037] The zigzag chute (118) allows the mixture flowing out of the automatic control valve (122) to be supplied to the upper screen member (132a) at a constant speed while being widely dispersed rather than being poured out all at once, thereby maximizing the sorting effect.

[0038] The supply unit (120) includes a cyclone separator (126) that vacuum sucks a mixture of black soldier fly larvae and vermicompost from a breeding tray (not shown), and an automatic control valve (122) that supplies the mixture flowing in from the cyclone separator (126) to the separation and sorting unit (130) at a constant flow rate.

[0039] An automatic control valve (122) is fixedly installed on the upper side of a subframe (114) such that its outlet end and inlet end face the outlet end of the zigzag chute (118) and the cyclone separator (126), respectively.

[0040] At this time, a sight glass (124) is installed vertically between the automatic control valve (122) and the cyclone separator (126) so that a worker can visually check the mixture flowing from the cyclone separator (126) to the automatic control valve (122).

[0041] Specifically, the bottom of the sight glass (124) is connected to the inlet side of the automatic control valve (122), and the top of the sight glass (124) is connected to the outlet side of the cyclone separator (126).

[0042] The automatic control valve (122) formed in this way opens and closes the flow path according to the control of the control unit (not shown) so that a constant flow rate of black soldier fly larvae and vermicompost mixture is supplied to the upper screen member (132a).

[0043] Here, the automatic control valve (122) may be a rotary valve or a feeder valve.

[0044] The cyclone separator (126) generates centrifugal force on the mixture and air flow vacuumed into it to separate the mixture (black soldier fly larvae and vermicompost) and the air, and the separated air is discharged to the outside through the upper air discharge pipe, and the separated mixture is discharged to the lower discharge end by gravity.

[0045] This cyclone separator (126) is connected to the top of the sight glass (124) as described above so that the outlet end faces the inlet end of the automatic discharge valve (122).

[0046] Here, vacuum suction of black soldier fly larvae and a mixture of vermicompost from a rearing tray placed in a rearing facility (not shown) using a cyclone separator (126) is intended to apply the sorting device (100) according to the present invention to mass production and smart farm environments to drastically reduce labor and working time and maximize production efficiency.

[0047] And since it is a known technique that the cyclone separator (126) vacuums the mixture from the breeding tray under the control of the control unit, a detailed description thereof is omitted.

[0048] The separation sorting unit (130) includes upper and lower screen members (132a, 132b) that have the same configuration and form a two-stage separation sorting structure.

[0049] The upper and lower screen members (132a, 132b) each include a mesh net (134) in which the mixture is separated and sorted, a mesh net frame (136) that supports the mesh net (134), and a side wall (138) that forms an outlet (140) on the other end of the mesh net frame (136).

[0050] These upper and lower screen members (132a, 132b) are installed so as to be inclined downward from one end to the other end of the main frame (112) via pivot members (170), spaced apart from each other in an upward direction, so as to receive the mixture flowing out from the automatic control valve (122) and the mixture passing through the upper screen member (132a), respectively.

[0051] At this time, the upper and lower screen members (132a, 132b) each receive rotational motion from the upper and lower drive motors (142a, 142b) installed on the main frame (112) and reciprocate in a straight line along the length direction of the main frame (112), thereby inducing the mixture to move smoothly according to its own weight.

[0052] Here, the rotational motion of the upper and lower drive motors (142a, 142b) is converted into linear reciprocating motion of the upper and lower screen members (132a, 132b) through a motion conversion mechanism, and the present invention does not specifically limit such a motion conversion mechanism.

[0053] For example, a rotating disk is installed on the output shaft of the upper and lower drive motors (142a, 142b), and the upper and lower screen members (132a, 132b) are each eccentrically connected to the rotating disk via a connecting rod so as to perform linear reciprocating motion.

[0054] And the mesh screen (134) of the upper screen member (132a) is formed to allow worm castings similar in size to black soldier fly larvae to pass through, while filtering out coarse worm castings that are relatively larger than black soldier fly larvae and discharging them through the discharge port (140), and the mesh screen (134) of the lower screen member (132b) is formed to allow worm castings to pass through, while filtering out black soldier fly larvae and discharging them through the discharge port (140).

[0055] At this time, a first vermicompost collection container (144) and a black soldier fly larva collection container (146) are installed at each discharge port (140) of the upper and lower screen members (132a, 132b), and a second vermicompost collection container (148) is installed on the lower side of the lower screen member (132b) to be connected to the first vermicompost collection container (144).

[0056] That is, the mixture supplied to the supply unit (120) flows through the automatic control valve (122) into the upper screen member (132a) of the separation and sorting unit (130), and at the same time, the upper and lower drive motors (142a, 142b) cause the upper and lower screen members (132a, 132b) to move in a linear reciprocating motion.

[0057] By the linear reciprocating motion of these upper and lower screen members (132a, 132b), among the mixtures introduced into the upper screen member (132a), the worm castings larger than the black soldier fly larvae are filtered by the mesh net (134) of the upper screen member (132a) and move along the downward slope of the upper screen member (132a) to be discharged to the first worm casting collection container (144), and the worm castings of the black soldier fly larvae and worm castings similar in size to the black soldier fly larvae pass through the mesh net (134) of the upper screen member (132a) and are introduced into the lower screen member (132b).

[0058] Then, among the mixture introduced into the lower screen member (132b), the black soldier fly larvae are filtered by the mesh net (134) of the lower screen member (132a) and move along the downward slope of the lower screen member (132b) to be discharged to the black soldier fly larva collection tank (146), and the worm castings pass through the mesh net (134) of the lower screen member (132b) and are discharged to the second worm casting collection tank (148).

[0059] Thus, the worm castings and black soldier fly larvae collected in the first and second worm casting collection tanks (144, 148) and the black soldier fly larva collection tank (146) are each transferred to a subsequent process through a vacuum suction device.

[0060] Preferably, the upper and lower screen members (132a, 132b) are formed of a corrosion-resistant material (e.g., stainless steel, aluminum, etc.) considering the characteristics of the black soldier fly rearing environment.

[0061] Meanwhile, the upper and lower screen members (132a, 132b) of the black soldier fly larva and worm casting device (100) according to the present invention are formed so that a worker can adjust the tension of the mesh net (134).

[0062] To this end, the mesh frame (136) surrounding the mesh net (134) is formed to have a cross-sectional shape in which grooves (150) and ridges (152) are formed in succession from the inside to the outside.

[0063] At this time, the mesh net (134) extends past the upper part of the groove (150) to the upper side of the ridge (152), and the mesh net (134) extended to the upper side of the ridge (152) is firmly fixed by mesh net fixing bolts (156) that are fastened to the ridge (152) to press the fixing bar (154) extended along the length direction of the mesh net frame (136) toward the mesh net (134).

[0064] And a tension adjustment bar (158) extending along the length direction of the mesh frame (136) is seated on the mesh (134) passing over the upper part of the groove (150), and the tension of the mesh (134) on which the tension adjustment bar (158) is seated is adjusted by a tension adjustment bolt (160) fastened to the bottom of the groove (150) to press the tension adjustment bar (158) into the inside of the groove (150).

[0065] That is, the operator can easily adjust the tension of the mesh net (134) by operating the tension adjustment bolt (160), and also easily replace the mesh net (134) with respect to the mesh net frame (136), so that the user can directly repair or replace the damaged mesh net (134), thereby reducing the cost of replacing and maintaining the mesh net (134).

[0066] In addition, the aforementioned pivot members (170) of the black soldier fly larva and worm casting device (100) according to the present invention not only pivotably support the upper and lower screen members (132a, 132b), but also support them in a height-adjustable manner.

[0067] The pivot member (170) includes a fixed bracket (172) with an "L" cross section fixedly installed on the main frame (112), a lifting bracket (174) with an "L" cross section slidably installed on the fixed bracket (172) in the up and down direction, and a pivot bar (182) pivotally connecting upper and lower screen members (132a, 132b) to the lifting bracket (174).

[0068] The upper end of the pivot bar (182) is pivotally connected to a pivot axis (184) formed in the lifting bracket (174). And a connecting bracket (186) with an approximately "U"-shaped cross section is pivotally connected to the lower end of the pivot bar (182).

[0069] The mesh frame (136) of the upper and lower screen members (132a, 132b) is inserted into the interior of the connecting bracket (186) and secured by bolts.

[0070] A through hole (176) of an elongated shape extending in the vertical direction is formed in the lifting bracket (174), and the lifting bracket is fixed to the fixing bracket (172) through a lifting bracket fixing bolt (178) that passes through the through hole (176).

[0071] Additionally, a height adjustment bolt (180) is fastened to the lower part of the fixed bracket (172), and the threaded extension end of the height adjustment bolt (180) contacts the lower part of the lifting bracket (174) to adjust the height of the lifting bracket (174).

[0072] That is, the operator loosens the tightening of the lifting bracket fixing bolt (178) so that the lifting bracket (174) is guided on the fixing bracket (172), and then operates the height adjustment bolt (180) to adjust the height of the lifting bracket (174). When the height adjustment is complete, the operator tightens the lifting bracket fixing bolt (178) again to firmly secure the lifting bracket (174) to the fixing bracket (172).

[0073] When the height of the lifting bracket (174) is adjusted in this way, the height and inclination angle of the upper and lower screen members (132a, 132b) can be adjusted through the pivot bar (182), thereby allowing for the setting of optimal sorting conditions suitable for the characteristics of the black soldier fly larva and the vermicompost mixture.

[0074] The black soldier fly larva and vermicompost sorting device (100) according to the present invention formed in this way can precisely adjust the tension of the mesh net (134) and the height and inclination angle of the upper and lower screen members (132a, 132b), so that the black soldier fly larva and vermicompost can be separated and sorted with high efficiency by always setting optimal sorting conditions regardless of changing environmental conditions such as humidity or particle size of the black soldier fly larva and vermicompost mixture.

[0075] The black soldier fly larva and vermicompost sorting device (100) according to the present invention can be applied to mass production and smart farm environments because the supply unit (120) vacuum sucks a mixture of black soldier fly larva and vermicompost from a rearing tray, and the replacement and tension adjustment of the mesh net (134) for the mesh net frame (136) is easy, thereby reducing the maintenance costs of the mesh net (134).

[0076] It is stated that the essential technical concept of the present invention is not limited to the embodiments described above, and encompasses a scope that can be easily proposed by a person skilled in the art through substitution or modification.

[0077] Furthermore, since the terms used in the description of the present invention are selected for the convenience of explanation, in grasping the essential technical concept of the present invention, they should not be limited to their dictionary meanings but should be appropriately interpreted in a sense consistent with the technical concept of the present invention.
