Description

Technical Field

[0001] The invention relates to the technical field of black soldier fly breeding, and in particular to a black soldier fly three-dimensional breeding system and a black soldier fly breeding method. Background Art

[0002] Black soldier flies are a resource insect widely distributed throughout the world. In the larval stage, they live a saprophytic life, have strong digestive ability, a wide range of diet, strong resistance to adversity, and do not carry pathogens. They can efficiently absorb nutrients from a variety of organic wastes, including kitchen waste, livestock and poultry manure, discarded fruits and vegetables, and convert them into their own nutrients, while eliminating environmental pollution and effectively improving the efficiency of resource utilization of organic waste. Black soldier flies have high utilization value whether they are larvae or adults, and have great application potential in the fields of organic waste conversion and feed.

[0003] The various characteristics of black soldier flies are gradually being applied to the breeding industry and organic matter treatment industry. Domestic related companies have noticed the black soldier fly's ability to efficiently convert organic matter. A black soldier fly breeding that relies on this characteristic has been valued by the breeding industry. It can not only process livestock and poultry manure produced in the breeding process, but also produce black soldier flies, a high-nutrition feed insect. There are three main methods of large-scale breeding of black soldier flies, namely, artificial breeding in small ground ponds, semi-mechanized breeding in long ground troughs, and multi-layer three-dimensional equipment breeding. Most of the devices that have been put into use on the market are relatively simple in function and can only achieve single black soldier fly larvae breeding or organic waste conversion of black soldier flies. In addition, most of the devices have large size limitations and cannot control the breeding costs at a low level while ensuring output.

[0004] At present, the domestic black soldier fly breeding industry is just starting. Although relevant breeding experience can already support the breeding of black soldier flies, the black soldier fly breeding equipment still has the following shortcomings: the equipment has high requirements for the site, low degree of modularization, and cannot adapt to all breeding environments; the level of automation is insufficient and still requires a lot of manual labor; the unit breeding cost is high, the equipment operating cost is high, and the profit margin is small. Summary of the invention

[0005] The purpose of the present invention is to overcome the above-mentioned problems existing in the prior art and to provide a black soldier fly three-dimensional breeding system and a black soldier fly breeding method. The scheme can improve the modularity level of the breeding device so that it can adapt to various breeding environments; improve the level of automation, reduce human labor costs; and reduce breeding costs.

[0006] In order to achieve the above-mentioned object, the present invention provides a three-dimensional black soldier fly breeding system, including breeding equipment, the breeding equipment including a breeding rack, the breeding rack is provided with a first breeding layer, a second breeding layer, a third breeding layer and a fourth breeding layer in sequence from top to bottom, and a conveyor belt is provided below the fourth breeding layer;

[0007] The first breeding layer includes a plurality of first breeding boxes arranged side by side; the second breeding layer includes a plurality of second breeding boxes arranged side by side; the third breeding layer includes a plurality of third breeding boxes arranged side by side; the fourth breeding layer includes a plurality of fourth breeding boxes arranged side by side;

[0008] The breeding equipment also includes a first tilting mechanism, a second tilting mechanism, a third tilting mechanism and a fourth tilting mechanism;

[0009] The first breeding layer can be driven by the first tilting mechanism to cause each first breeding material box to tilt in a linked manner, so that the material in each first breeding material box is poured into the corresponding second breeding material box in the second breeding layer;

[0010] The second breeding layer can be driven by the second tilting mechanism to make each second breeding material box tilt in a linked manner, so that the material in each second breeding material box is poured into the corresponding third breeding material box in the third breeding layer;

[0011] The third breeding layer can be driven by the third tilting mechanism to make each third breeding material box tilt in a linked manner, so that the material in each third breeding material box is poured into the corresponding fourth breeding material box in the fourth breeding layer;

[0012] The fourth breeding layer can, driven by the fourth tilting mechanism, cause each fourth breeding material box to tilt in linkage, so that the material in each fourth breeding material box can be poured into the conveyor belt.

[0013] A second aspect of the present invention provides a method for breeding black soldier flies, which is implemented in the above-mentioned three-dimensional breeding system for black soldier flies, and specifically comprises the following steps:

[0014] Put the first breeding material and black soldier fly larvae into each first breeding material box of the first breeding layer on the breeding rack, breed the black soldier fly larvae in the first breeding layer for a first preset time period, and then continue to put the second breeding material into each first breeding material box, and then the first breeding layer is driven by the first tilting mechanism to make each first breeding material box tilt in a linked manner, so that the material in each first breeding material box is poured into the corresponding second breeding material box in the second breeding layer;

[0015] After the second breeding material boxes of the second breeding layer receive the materials from the first breeding layer, they continue to breed the black soldier fly larvae therein for a second preset time period, and then the second breeding layer, driven by the second tilting mechanism, causes each second breeding material box to tilt in a linked manner, so that the materials in each second breeding material box are poured into the corresponding third breeding material box in the third breeding layer;

[0016] After the third breeding material boxes of the third breeding layer receive the materials from the second breeding layer, the third breeding material is put into each third breeding material box to breed the black soldier fly larvae therein for a third preset time period, and then the fourth breeding material is put into each third breeding material box. Then, the third breeding layer is driven by the third tilting mechanism to make each third breeding material box tilt in linkage, so that the materials in each third breeding material box are poured into the corresponding fourth breeding material box in the fourth breeding layer;

[0017] After the fourth breeding material box of the fourth breeding layer receives the material from the third breeding layer, it continues to breed the black soldier fly larvae therein for a fourth preset time period. Then, driven by the fourth tilting mechanism, the fourth breeding layer causes each fourth breeding material box to tilt in conjunction, so that the material in each fourth breeding material box is poured into the conveyor belt, and the conveyor belt transports the material out of the breeding equipment.

[0018] The present invention can reduce breeding costs and improve breeding efficiency by designing a special breeding rack; the tiltable breeding layer designed by the present invention can allow the material of the current layer to fall into the next layer, leaving the current layer empty, which is convenient for another laying operation; and through such a tilting and flipping, the effect of artificial loosening in breeding can be achieved, preventing the material from being compacted and causing damage to breeding.
