Pushing device, the pushing device pushes each black soldier fly larvae from the starting position to the insect throwing port 10 of the housing 8, so that a certain amount of black soldier fly larvae falls out from the insect throwing port 10;

Control device, the control device can control the heat preservation device to maintain it at 5-15°C, and the control device can control the distance of each push of the push device and the time when the push is initiated.

The thermal insulation device is mainly used to control the internal temperature of the housing 8, and any temperature control device on the market can be used. The thermal insulation device used in this embodiment includes an air channel 7 on the inner wall of the pipeline, an insulation layer 9 on the outer wall of the pipeline, and a temperature control device and a temperature sensor 6 in the air channel 7 . Using the air channel 7 can effectively reduce the weight of the device, and the air insulation effect is very good. The temperature control device mainly plays a heating and cooling role to maintain the heat preservation in the housing 8 at a set temperature. A general breeding environment requires cooling equipment, but any colder places will also require heating equipment, which can be selected according to the actual situation. This embodiment is mainly set for places where the breeding environment temperature is higher than 15°C. The temperature control device is an electronic refrigeration device 5, which is mainly an electronic refrigeration chip (or semiconductor refrigeration chip). The electronic refrigeration chip does not require any refrigerant and can work continuously. It has no pollution sources, no rotating parts, and no rotation effect. It has no sliding parts and is a solid piece. It has no vibration or noise during operation, has a long life, and is easy to install. Semiconductor refrigeration chips have two functions, both cooling and heating. The cooling efficiency is generally not high, but the heating efficiency is very high, always greater than 1. Therefore, separate heating and cooling systems can be replaced with one piece. The semiconductor refrigeration chip is a current conversion chip. By controlling the input current, it can achieve high-precision temperature control. Coupled with temperature detection and control means, it is easy to realize remote control, program control, and computer control, making it easy to form an automatic control system. The thermal inertia of the semiconductor refrigeration chip is very small, and the cooling and heating time is very fast. When the hot end has good heat dissipation and the cold end is no-load, the refrigeration chip can reach the maximum temperature difference in less than one minute after powering on.

When the electric push rod starts, the electric valve opens. When the electric push rod stops moving, the electric valve delays for a period of time, allowing the black soldier fly larvae to be completely released into the breeding box. , and then close.

The operation process of the present invention:

(1) First, slowly cool down the black soldier fly larvae that meet the insect feeding requirements to 5-15°C, so that the black soldier fly larvae is in a dormant state and set aside; the slow cooling is: put the black soldier fly larvae into the incubator inside, and then place the incubator in a cold storage or freezer at 5-15°C. When the temperature in the incubator drops to the predetermined temperature, set it aside.

(2) Turn on the insect throwing system, set the weight of each insect throwing, the time between each insect throwing, the moving distance of the pushing device and the temperature inside the shell through the control device, and then place the dormant black soldier fly larvae quantitatively in the In the dosing device for black soldier fly larvae;

(3) During operation, the thermal insulation device detects and controls the temperature inside the shell to be 5-15°C to keep the black soldier fly larvae in a dormant state;

(4) The pushing device pushes the black soldier fly larvae out of the shell regularly and quantitatively according to the set time and moving distance (or rotation time, etc.) and puts them into the breeding box;

(5) Repeat step (4) to release black soldier fly larvae multiple times over multiple days.
