Description

Automatic screening device and insect breeding system for insect breeding

Technical Field

The invention mainly relates to the field of insect breeding equipment, in particular to an automatic screening device for insect breeding and an insect breeding system.

Background

In the current society, insect breeding has certain industrial economic value. For example, yellow mealworms are the most ideal feed insects for artificial breeding, have high nutritional value, can be directly used as living animal protein feeds for feeding frogs, turtles, scorpions, centipedes, ants, high-quality fishes, spectacular birds, medicinal animals, precious fur animals, rare livestock and poultry and the like, can be used in the industries of food, health products, cosmetics and the like after being processed, and are praised as a 'treasure house of protein feeds' due to high protein nutritional ingredients in various living animal protein feeds.

Taking yellow mealworm as an example, the life cycle of the yellow mealworm is divided into four parts of egg, larva, pupa and imago, the yellow mealworm is cultured from the egg of the yellow mealworm, the yellow mealworm can be used for raising commercial products such as pets after the yellow mealworm grows into mature larva, and the pupa and the imago are used as seed and spawn for the next batch of culture. In the process of larva breeding and growing, the volume of the larva is gradually increased, so that the breeding area of the larva needs to be continuously increased to ensure that the breeding density of the larva is within a certain range, otherwise, the larva can be mutually extruded to seriously affect the growth. Meanwhile, the insect feces are generated in the growth process, and the insect skin is sloughed for multiple times along with the growth, which also needs to be separated in time, because the separated insect feces and insect skin can be used for other commercial production, for example, the insect feces is prepared into fertilizer, the insect skin is prepared into medicine, and the commercial value is generated in time; and secondly, if the separation is not carried out, the culture environment and the culture area are influenced, and the growth of the culture medium is further influenced.

The structure form can not occupy the storage space of the culture disc, and can ensure that the first driving shaft 236 is stably driven, thereby effectively ensuring the stability and the precision of the transportation of the culture disc.

As shown in fig. 1, 5, 6 and 7, further, in a preferred embodiment, the screening mechanism 7 includes a fan assembly 71, an insect collecting chamber 72, an insect skin conveying chamber 73, an insect feces collecting chamber 74 and a vertically arranged main channel 75, the top opening of the main channel 75 is used for communicating with a discharge opening at the bottom of the receiving hopper 11, the bottom opening of the main channel 75 is communicated with the insect collecting chamber 72 to enable the insect to directly fall into the insect collecting chamber 72, the vertical side wall of the main channel 75 is further provided with a first screening opening (X shown in fig. 5) and a second screening opening (Y shown in fig. 5) which are arranged up and down, the first screening opening at the upper part is used for communicating with the insect skin conveying chamber 73, the second screening opening at the lower part is used for communicating with the insect feces collecting chamber 74, the fan assembly 71 is arranged corresponding to the first screening opening and the second screening opening and is used for providing air blowing opening or air draft opening towards the first screening opening and the second screening opening, So that the insect skin and the insect feces with different masses enter the insect skin conveying chamber 73 and the insect feces collecting chamber 74, respectively, under the action of wind.

In this embodiment, the blower assembly 71 is a blower disposed just opposite the first and second sifting openings for blowing air toward the first and second sifting openings. The mass of the worm body, the worm skin and the worm feces is inconsistent, so that the worm body is the heaviest, and the worm feces is the lightest and the worm skin is the lightest. When the bodies, skins and dung fall down through the main channel 75, the bodies with the highest mass do not receive the influence of the air blowing, but fall directly into the body collecting chamber 72 below and are collected (as shown by the arrow M in fig. 5). As soon as the lightest weight of the bark enters the main channel 75 and has not yet fallen downwards, it is blown into the uppermost first screen opening and then into the bark transfer chamber 73 for collection (as indicated by the arrow N in fig. 5). And the insect dung with certain mass falls and is influenced by wind force at the same time, and then is blown into the second screening opening below the first screening opening, and then enters the insect dung collecting chamber 74 and is collected (as shown by an arrow P in figure 5).
