The purpose of the invention is realized by the following technical scheme:

a black soldier fly larva breeding device based on inclined transfer comprises a larva breeding chamber and a plurality of breeding boxes arranged in the larva breeding chamber;

wherein the plurality of cultivation boxes are arranged in a vertical direction; the black soldier fly larvae are divided into a plurality of stages of the insect ages according to the insect ages from small to large, and the black soldier fly larvae are sequentially cultured in a plurality of culturing boxes arranged from top to bottom according to the order of the insect ages from small to large;

breed the box and connect in the larva breeding chamber through the mechanism that can down overturn, the one end that the upset center was kept away from to this breed box is equipped with the larva and shifts the export, and this larva shifts the exit and is equipped with and is used for controlling the larva to shift the transfer switch mechanism that the export opened or closed.

The working principle of the black soldier fly larva breeding device based on inclined transfer is as follows:

during work, feed is put into the breeding boxes, then the eggs of the hermetia illucens are put into the breeding boxes positioned at the top, and the eggs are hatched and then continuously fed and grow in the current breeding boxes. When the larvae grow to the second instar, they need to be transferred to the next habitat:

rotating the current culture box by a certain angle around the overturning center, wherein in the process, the larva transfer outlet rotates downwards, and the whole culture box inclines downwards; before or simultaneously, the larva transferring outlet is opened through the transferring switch mechanism, under the action of self gravity, the larva automatically falls into the cultivating box positioned below from the current cultivating box, continues to grow in the cultivating box below until the larva grows to the third age, and then sequentially transfers downwards according to the same transferring mode. Further, in the flowing water type larva transfer, the larva transfer work can be started only by ensuring that the culture box below is in an empty state or filled with fresh feed.

According to the breeding mode, the larvae are sequentially converted into growing places along the plurality of breeding boxes until pupate in the last breeding box, and then are transferred out to be bred by the next breeding module.

In a preferred aspect of the present invention, the plurality of rearing boxes are provided alternately on two opposite inner walls of the larva rearing chamber in the vertical direction.
