Description

Fermentation bed for complete degradation of chicken manure in laying hen farms

Technical field:

The utility model relates to laying hen breeding technology, in particular to a fully degradable fermentation bed for chicken manure in laying hen farms.

technical background:

After more than 20 years of development of the laying hen industry in my country, the current stock of laying hens is 1.5 billion, and has continuously become the country with the largest egg production in the world. Over the years, it has been increasing at a rate of 3% to 5%. Now my country's per capita consumption has reached 20 kg, which is close to the consumption level of developed countries.

But at the same time, as a large livestock production and consumption country, the extensive economic growth mode of animal husbandry for many years in my country has resulted in the continuous development of large-scale breeding production and the relatively lagging status of environmental protection governance, breaking the traditional "livestock-fertilizer". - Grain” virtuous cycle pattern, the environmental pressure caused by the industry development process is increasing. The comprehensive utilization rate of poultry manure and product processing waste is low, and problems such as waste of resources and environmental pollution are becoming increasingly apparent, which not only restricts the development of the laying hen industry itself to a certain extent, but also has nothing to do with improving the quality of life of farmers and building a well-off society in an all-round way. adapt.

Animal husbandry, as the central axis industry of undertaking agriculture and starting work, is an important link in the development of circular economy and low-carbon economy. Leading the development of animal husbandry with the concept of circular economy and low-carbon economy is an effective way to fundamentally reduce the environmental pollution of animal husbandry, promote the harmonious development of economy and ecology, and the harmony and unity between man and nature; it is also an effective way to promote the economic growth of animal husbandry from extension to growth It is an important measure to change to the simultaneous growth of quality, environmental protection and efficiency. The "1+1" new industry development model of "circular economy" + "low-carbon economy" will surely become an important part of promoting the healthy and stable development of my country's laying hen industry.

At present, various aquaculture manure treatment technologies, mostly simply absorb urban sewage or garbage treatment technologies and processes, have large one-time investment, high cost, complicated operation, and unsatisfactory results. It is urgent to establish a new type of low-cost, resource-saving and environmentally friendly. Farming manure treatment technology.

The culture technology of microbial composite bacteria fermentation bed is based on the principle of microecology and biological fermentation theory, mixing sawdust, chaff, straw powder, etc. in a certain proportion, and laying them in the fermentation mattress trough vertically below the laying hen cage to assist the composite bacteria The starter is mixed evenly with the bedding according to a certain ratio, and the entire fermentation bedding is drenched with clean water, and finally covered with a nylon film to ferment for 3 to 7 days to form a microbial fermentation bed. The use of microbial complex bacteria to degrade chicken manure in situ achieves a new ecological and environmentally friendly "zero discharge" farming model.

Fermentation bed culture technology emerged in Japan in the 1970s. my country introduced and applied this technology in the 1990s. Now it is mainly promoted regionally in Guangdong, Fujian, Shandong, Henan, Hunan, Guangxi and other provinces, and the technology has been further improved. and development, but due to the relatively special breeding environment of laying hens, most of them are raised in cages, resulting in the traditional fermentation bed breeding technology still unable to meet the requirements of laying hens.

Utility model content:

In order to overcome the technical problems of manpower cleaning the feces and washing pens in traditional laying hen breeding, the utility model provides a fermentation bed that can effectively degrade chicken manure in laying hen farms.

The purpose of this utility model is achieved in the following ways:

The chicken manure degradation fermentation bed of the laying hen farm provided comprises a drinking device (1) and a litter tank (5) equipped with litter, and is characterized in that the ground below the chicken cage is composed of a fermented mattress tank (5), The side wall of the trough is equipped with a fixed track (4), an automatic bedding rake machine (6) is installed on the track, and an automatic spraying bacteria replenishing system (3) is installed under the chicken cage. The nozzle of the automatic spraying bacteria replenishing system is parallel to the litter layer .

The fermented bedding tank described in the utility model can adopt underground type, that is, dig 30cm～60cm from the vertical surface of the chicken cage, and be surrounded by outer walls and side walls; semi-underground type, that is, dig 15cm～30cm from the ground, and use bricks 15cm to 30cm; the ground type uses bricks to build a 30cm to 60cm pool on the vertical ground plane of the chicken cage, and the track of the automatic rake machine is fixed on the side wall. , The bottom of the drainage ditch around the chicken house is 30-50cm lower than the bottom of the fermentation bedding tank. Fermentation bedding is housed in the tank, and the bedding layer is 20-40 cm thick.

Notable features of the present utility model are:

1. During the process of raising laying hens using the fermentation bed breeding technology, the microbial complex bacteria in the fermented bedding material can degrade the chicken manure falling on the bedding material in time, and at the same time, the microorganisms in the bedding material need to be consumed due to the degradation of chicken manure For complex bacteria, special attention should be paid to the supplementary plan of microbial complex bacteria when designing the fermentation bed of the chicken house.

2. An automatic litter raking machine with a fixed track is installed above the litter layer, which can turn the chicken manure falling on the litter into the litter, so that the chicken manure and the microbial complex bacteria in the litter can be fully contacted, In this way, the chicken manure is completely degraded by the microbial complex bacteria in the litter.

3. Due to the use of mechanization in the fermentation bed bacteria replenishment and bedding raking, and the use of microbial complex bacteria in the degradation of chicken manure, the chicken house will not often wash the floor, chicken cages and ammonia gas produced by chicken manure due to the production of chicken manure. It can save manpower, material resources and financial resources, greatly improve the breeding efficiency and improve the breeding environment.

Description of drawings:

Fig. 1 is the cross-sectional view of the fully degradable fermentation bed of chicken manure in a laying hen farm of the present invention.

Detailed ways:

As shown in the figure: the composition of the full-degradation fermentation bed for chicken manure in the laying hen farm, in addition to the necessary chicken cage 2 and drinking water device 1, also added litter tank 5, litter 7, and fixed rails installed on the side wall of the tank 4. An electric rake turning machine is installed on the track. 6. An automatic spraying bacteria replenishing system3.

The structure of the fermentation bed:

1. Dig a groove with a depth of 40 cm on the vertical ground of the laying hen cage, and build it with bricks around it.

2. A fixed track is installed on the side wall of the bedding trough, and an automatic bedding rake machine is installed on the track, which is mainly used for turning the bedding material.

3. The automatic spraying bacteria replenishing system is installed under the chicken cage. The nozzle is facing and parallel to the litter layer. It is usually closed. When the ability of the litter to degrade chicken manure declines, the automatic spraying system will replenish microbial complex bacteria.
