Description

A standardized device for collecting black water fly worm eggs

Technical field

The invention relates to the technical field of making insect breeding appliances, in particular to a standardized device for collecting black water fly worm eggs.

Background technique

Heishui Fly (Hermetia illucens) is a new type of feed resource insect, which has been promoted nationwide. It is widely used in the resource treatment of food waste, poultry manure and other waste, as well as the production of high-quality animal-derived protein feed. At present, black water fly insects have been used as animal feed in poultry breeding and aquaculture. Aquaculture has become an emerging industry that has attracted much attention. Among them, the collection of black water fly worm eggs is one of the key links in water fly breeding, and the collection of black water fly worm eggs requires corresponding mobile phone devices.

The existing egg collection devices in the industry mainly have the following schemes:

Wood chip stacking method: The commonly used spawning boards are stacked wooden blocks, the size is 10 mm thick, 3-8 cm wide, and 20-30 cm long. When stacking, use thumbtack caps or toothpicks, etc. There is a gap of about 1 mm between the black water flies to lay their eggs. This device is mostly made by the farmers themselves, and there is no uniform standard. The weight of this spawning board is very large, and a spawning board with a weight of 500 grams can only harvest 20 grams of eggs (the egg collection efficiency is 20:500 = 1/25), and the device itself is also bulky. Because of the extremely low egg collection efficiency, the eggs cannot be mailed together with the spawning board when mailing the eggs, and the eggs need to be manually scraped from the spawning board. Because the eggs are very fragile, they will cause at least 5% loss during the scraping process, and a lot of labor is required. The eggs harvested by this device are easy to form a cluster during the bumpy transportation, causing a large number of eggs to die due to lack of oxygen. It is easy to mold after repeated use and can only be replaced. The advantage of this device is that the raw materials are easily available. It only costs 7-8 yuan to make a 500g device, which can be reused, and the odor of eggs can be retained, which can enhance the effect of attracting egg-laying adults.

Corrugated paper stacking method: stack corrugated paper sheets (each layer 2-5 cm wide and 5-20 cm long) in multiple layers, and let the black water fly adults lay eggs in the small holes in the cross-section of the corrugated paper. This device is mostly produced by farmers, and the raw materials are simple and easy to obtain, but the different thickness of a variety of corrugated cardboard causes different egg collection efficiency. It can be customized from the corrugated paper manufacturer to solve the standardization problem. Only a device with a weight of about 50 grams is required to harvest 20 grams of eggs (egg collection efficiency is 1/2.5). The device itself is small in size and can be used for mailing. The disadvantage is that it cannot be reused, the production process is cumbersome, and it consumes a lot of labor. When the eggs block the two ends of the hole, the eggs in the middle part are prone to hypoxia and die, and the small larvae that hatch in the middle are also easy to crawl out because of the blockage of the hole, and eventually die inside the device. Because of the complex structure of corrugated paper, it is very inconvenient when pure eggs need to be collected. The corrugated paper structure can only be disassembled layer by layer, and the eggs are easily lost in the process. Because there is no standardized production, it can only be estimated when calculating the egg production.

At present, some companies have developed egg collection devices made of plastic and other materials, which can be reused, but Heishui Fly itself does not like unnatural materials. The egg collection efficiency is generally between the wood block device and the corrugated paper device.

It can be seen from this that the current blackwater flyfly egg collection device has various shortcomings, which cannot meet the needs of industrialized collection of blackwater flyfly eggs.
