Description

Technical Field

[0001] The invention relates to the technical field of feces cleaning and recovery devices, and in particular to a feces cleaning and recovery device for animal husbandry farms. Background Art

[0002] Chicken farms refer to places used to raise and breed poultry. They are an important part of modern animal husbandry, and they achieve efficient production and breeding of livestock through scientific feeding management, disease control and environmental control.

[0003] Since chicken farms raise a large number of poultry, they will produce a lot of animal manure. Chickens have short intestines, and about 70% of the nutrients in the feed are excreted without being absorbed. Therefore, chicken manure contains high crude protein, calcium and other nutrients, which is suitable as a raw material for feed or organic fertilizer. Chicken manure can be used as a raw material for biochar, and after recycling, it can be processed for carbon sequestration, adsorbents, fuels and soil additives. If poultry manure is not cleaned and treated in time, it will directly pollute the soil, water and air around the farm. Compared with traditional manual cleaning methods, the manure cleaning and recycling device driven by mechanical equipment can greatly reduce the input of labor, reduce labor costs, and prevent cleaners from being infected by bacteria, viruses and parasites.

[0004] Most of the existing livestock farm manure cleaning devices use simple mechanical cleaning methods, which have low cleaning efficiency and insufficient solid-liquid separation, resulting in difficulties in subsequent treatment. Most of them use dry-wet separation after squeezing, and use a dispersing mechanism to disperse the manure residue. However, the above devices have the following technical problems when used: 1. Chicken manure is usually in the form of granules or blocks, but some chicken manure has a high water content. After mixing with normal chicken manure, the overall viscosity increases, and the manure is easy to adhere to the inside of the equipment, making it difficult to clean. After cleaning the manure, it is difficult to ensure the cleanliness of the device, and the equipment needs to be cleaned frequently; 2. Since chicken manure particles are small and contain water, it is difficult to separate the solid and liquid of chicken manure and discharge the solid manure after separation, resulting in time-consuming cleaning and recycling and low efficiency; Based on this, we propose a feces cleaning and recycling device for livestock farms to solve the technical problems raised in the above background technology.
