Excrement insect culture device capable of automatically separating insects from excrement and culture method thereof

Abstract

The invention relates to an excrement insect culture device capable of automatically separating insects from excrement and a culture method thereof. The device and the method are used for culturing maggot excrement and insect excrement in a large amount and capable of achieving automatic separation of insect excrement. The culture device mainly comprises a culture pool, the bottom of the culture pool is of a gravel cement structure, the peripheral wall of the culture pool is of a brick mixing structure, the pool face of the culture pool is provided with a slope, two sides are high, and the middle is low. A water discharge pipe as long as the culture pool is embedded under the low middle of the culture pool, sewage discharge holes vertically connected with the water discharge pipe are arranged above the water discharge pipe at intervals, and an insect collection bag capable of leaking water is sleeved in the sewage discharge holes. A row of plate blocks are arranged above the middle water discharge pipe of the culture pool, the laying length of the plate blocks is identical with that of the culture pool, and excrement is arranged in ridge in the culture pool. The excrement insect culture device has the advantages of reducing device construction cost of insect culture by excrement, reducing employment cost, improving insect breeding efficiency and being high in space utilization ratio, simple in structure, capable of conducting mechanical large-scale production, capable of automatically separating insect and excrement and conveniently collecting insects, easy in cleaning and the like.

Description

technical field [0001] The invention relates to a feces insect breeding device for automatic separation of insect excrement and a breeding method thereof, belonging to the field of animal breeding. Background technique [0002] Pork is a necessity in people's life, and pig raising is an important vegetable basket project of the government. Ten thousand pig farms have more than 20 tons of feces a day, and the disposal of feces has become a problem, and the feces pollution is very serious. At present, the technology of using feces to raise insects is immature, and the following problems generally exist: [0003] (1) The design of the breeding device is unreasonable, and the breeding pond is small, generally a small pond of 2-4 square meters. Even if it is a large space, it is composed of dozens or hundreds of such small ponds. The breeding pond is small, and the walls of the breeding pond limit the crawling of insects and mechanized operations. It is almost a cart plus a hoe,...

AI Technical Summary

Problems solved by technology

[0003] (1) The design of the breeding device is unreasonable, and the breeding pond is small, generally a small pond of 2-4 square meters

Even if it is a large space, it is composed of dozens or hundreds of such small ponds. The breeding pond is small, and the walls of the breeding pond limit the crawling of insects and mechanized operations. It is almost a cart plus a hoe, which cannot be separated Manpower operation, neighborhood work, small fights

[0004] (2) The collection of farmed insects is unreasonable. Manual operation is used to allow maggots to see the light and drill down into the feces, and the feces are slowly separated layer by layer, or the insects in the feces are washed with water with a sieve, Run off feces, leaving insects, more serious pollution

[0005] (3) There is no gully isolation zone around, and natural enemies that prey on insects go in to prey and reproduce in large numbers, which seriously interferes with production

[0006] (4) Lack of biological and behavioral knowledge of cultured insects, unscientific breeding methods, inconvenient operation, labor-intensive and time-consuming use of a lot of manpower and material resources, high cost and low efficiency
