Description

TECHNICAL FIELD

[0001] The present application relates to the field of livestock excrement treatment, in particular to a cattle manure collecting and crushing device and method thereof. BACKGROUND

[0002] China's livestock industry has entered a period of rapid development, and the output value of livestock in agriculture is also increasing. However, with the change of livestock feeding mode and the continuous expansion of feeding scale, it directly leads to the increase of fecal discharge density of grassland cattle, sheep and other organisms, causing the burning of seedlings and other influences in some areas, and the serious disconnection between agriculture and animal husbandry, which has a negative impact on the grassland ecological environment.

[0003] Grazing is one of the main ways of grassland utilization. Grazing livestock not only affects the morphological characteristics and physical structure of grassland through grazing and trampling, but also changes the soil chemical properties and nutrient material circulation through the transformation of nutrients by livestock and the return of excrement, thereby increasing the soil pH, electrical conductivity, microbial biomass and enzyme activity, and improving the fertility of the soil below and around the fecal patch by increasing the input of soil phosphorus and inorganic nitrogen. In the grassland ecosystem, the biogeochemical pathway of nitrogen mainly occurs between the atmosphere, soil, plants, animals and microorganisms, which can be divided into internal circulation and external circulation. The external circulation process refers to the process of input and output of nitrogen to and from the ecological system. The internal circulation process refers to the transformation of chemical forms of nitrogen and the transfer process between different reservoirs in the system. The internal circulation process of nitrogen has a much larger flux than the external circulation. The process of soil nitrogen transformation in grassland is an important part of internal circulation, which is of great significance to reveal the mechanism of grassland ecosystem function and biogeochemical cycle. As an important component of fecal nutrients, nitrogen accounts for about 75-95% of the nitrogen intake of livestock, and plays a crucial role in the biogeochemical cycle of nitrogen in grassland soil. The nitrogen in feces mainly includes total nitrogen, organic nitrogen, ammonium nitrogen and nitrate nitrogen. Among them, organic nitrogen accounts for about 90%, mainly including amino acid nitrogen, amino sugar nitrogen, acid ammonium nitrogen and non-acid ammonium nitrogen components. Only under the action of soil animals and microorganisms, it can be transformed into inorganic nitrogen and be absorbed and utilized by plants. About 20-25% of the nitrogen in feces is water-soluble, representing the metabolic products of intestinal animal and microbial populations; about 15-25% is undigested dietary nitrogen, and the remaining 50-65% exists in bacterial cells.

[0004] Cow dung is cold fertilizer because of its fine fecal quality, high water content, poor aeration, slow decomposition, and low fermentation temperature. The nutrient content of cow dung is low, especially the nitrogen content, and the carbon-nitrogen ratio is high (average 21). Based on the above characteristics, if the dung produced by cattle is not treated, it is usually piled on the ground, and it is easier to form a hard shell on the surface, making it difficult to mix with the soil. The impact of dung on soil microorganisms tends to be slow, and it often takes a long time for the dung to fully decompose into the soil. Long-term storage of livestock manure contains nitrogen compounds that can increase soil nitrate content through biochemical reactions such as ammonification, nitrification, and denitrification. Cattle dung often has an inhibitory effect on vegetation growth in the early stages because the coverage of dung prevents photosynthesis, which can cause ecological risks. Cow dung needs to be treated before it can be applied to the land. Grazing cattle on grasslands produce a large amount of cow dung, which has many impacts on the grassland ecosystem. The fragmentation and slow decomposition of cow dung trap nutrients in the dung, leading to nitrogen loss and reduced nutrient turnover. Cow dung piles occupy a certain area of grassland, and cattle refuse to eat the grass around the pile, causing waste of some grassland resources and reduction of primary productivity. Cow dung is a breeding ground for flies, which can bite and suck the blood or lick the secretions of cattle, disturb the cattle, reduce their nutrition, and spread diseases, causing significant economic losses to the livestock industry.

[0005] Current methods for treating cow dung include natural and artificial methods. Natural methods involve decomposition by microorganisms in the air, which is a slow process or can be accelerated by fragmentation by insects such as dung beetles. Artificial methods include three aspects: feed utilization of cow dung biomass resources, energy utilization of cow dung biomass resources, and fertilizer utilization of cow dung biomass resources.

[0006] Feed utilization of cow dung biomass resources:

[0007] 1. Fermentation method: adding certain microbial agents or enzyme preparations and other auxiliary materials, then fermenting at a suitable temperature.

[0008] 2. Decomposition method: using lower animals such as flies, earthworms, and snails to decompose the dung, but the pre-treatment of sterilization and dehydration and the post-treatment of collecting fly larvae, feeding earthworms, and snails are technically difficult, require harsh temperatures, and are difficult to produce throughout the year, so they have not been widely promoted. 3. Natural drying method: mixing fresh cow dung with a certain proportion of bran, then spreading it on a cement floor or plastic cloth. This method is low-cost and easy to operate, but it is affected by weather and can cause environmental pollution.

[0009] Energy utilization of cow dung biomass resources:

[0010] 1. Pyrolysis of manure: dried manure is directly combusted as fuel. This method is not fully utilized and can cause secondary air pollution. For large amounts of manure produced by intensive livestock farms, it is difficult to dry due to high water content, and must be converted before being used as fuel.

[0011] 2. Ethanol utilization: ethanol can be produced by replacing grain, thereby creating huge economic benefits. Currently, there is no related report on industrial production.

[0012] 3. Hydrogen utilization: a method for effectively converting wheat straw waste into biological hydrogen through manure composting. Currently, there is no related report on industrial production.

[0013] 4. Biogas utilization: a technology for producing biogas through microbial fermentation of manure. This process is mature, and many places have established biogas pools. However, it requires a large area and a large investment.

[0014] 5. Power generation: biogas produced by anaerobic fermentation of manure is used for power generation, which is suitable for large-scale farms or breeding areas.

[0015] Fertilizer utilization of manure biomass resources:

[0016] 1. Direct application: directly sprayed in the field, which can provide nutrients for crops and eliminate some soil diseases. Due to high water content, it is not convenient to use in large quantities and can cause secondary environmental pollution, limiting its use.

[0017] 2. High-temperature aerobic composting method: manure, efficient fermentation microorganisms such as effective microorganisms, and conditioners (such as straw, sawdust, etc.) are mixed in a certain mass ratio for aerobic fermentation treatment. It is greatly affected by environmental factors and needs to be adjusted in real time.

[0018] 3. Vermicomposting method: vermicomposting mainly combines vermicomposting with composting to produce vermicomposting feed and use composting for pollution-free vegetable cultivation. During the composting process, if anaerobic fermentation occurs, methane, CO, and other gases are produced, which greatly threaten the survival rate of earthworms.

[0019] Manure is a good organic fertilizer, but long-term accumulation of manure on the ground brings more harmful effects to grassland. Therefore, how to speed up the fragmentation and decomposition of manure is the key to destroying the breeding sites of harmful flies, reducing nitrogen loss, and speeding up the turnover rate of nutrients.

[0020] Therefore, the existing technology and measures need to be improved and developed. SUMMARY
