[0002] Feed cost in beef cattle breeding is one of the main costs of breeding. Reducing feed cost can increase the profit of beef cattle breeders.

[0003] Poultry farms produce a large amount of chicken manure every day. Due to the short digestive tract of chickens, they cannot completely absorb feed. The excreted chicken manure contains a large amount of nutrients in the feed, including 65% organic matter, 30% crude protein, and about 8% nitrogen, phosphorus and potassium. If it can be reasonably utilized, it can not only solve the problem of environmental pollution, but also turn waste into treasure and improve the utilization rate of materials. For this reason, the present invention provides a method for processing chicken manure fermented feed. Summary of the invention

[0007] Preferably, the planetary stirring assembly comprises: A stirring motor, wherein the stirring motor is fixedly mounted on the top plate of the frame-shaped bracket, and an output shaft of the stirring motor passes downward through the top plate; A rotating frame, the rotating frame is fixedly mounted on the output shaft of the stirring motor, and the side of the rotating frame has a plurality of stirring brackets distributed in an annular manner; A stirrer is fixedly mounted on the side of the stirring bracket, and a side plate is fixedly connected to the side of the stirrer.

[0008] Preferably, the feeding pipe of the vacuum feeder comprises: a first hose and a telescopic bellows, one end of the telescopic bellows is fixedly connected to one end of the first hose, and one end of the first hose away from the telescopic bellows is connected to the vacuum feeder; A sliding opening is provided on the top plate of the frame-shaped bracket, a sliding block is slidably installed in the sliding opening, and the sliding block is fixedly connected to the side surface of the first hose.

[0013] The beneficial effects of the present invention are as follows: Compared with the prior art, 1) The present invention uses fresh chicken manure, dry distiller's grains, and syrup as raw materials to prepare feed, and ferments for about 20 days in a sealed environment with the participation of yeast to obtain feed with a water content of 18%-22%. Since the main components of the raw materials are fresh chicken manure and dry distiller's grains, the acquisition cost is relatively low, thus greatly reducing the feed cost and improving the profit of beef cattle breeders; In the present invention, the organic matter, crude protein, nitrogen, phosphorus, and potassium in chicken manure are fully utilized. The syrup in the prepared feed provides energy, and the dry distiller's grains provide high fiber, which helps beef cattle gain weight; The present invention uses a pressure-center type stirring device to stir the preliminary mixture, which has multiple steps of extrusion, crushing, and stirring, and can ensure that the water content of dry distiller's grains and fresh chicken manure is consistent; 2) The participation of yeast in the fermentation process of the present invention improves the conversion of nitrogen sources in the feed and increases the content of protein and vitamins in the feed. The fermented feed is rich in organic matter (about 65%), crude protein (about 30%), and nitrogen, phosphorus, and potassium elements (about 8%). Moreover, the syrup serves as an energy source, and the dry distiller's grains provide sufficient high-fiber substances to meet the nutritional needs of beef cattle. Long-term consumption helps improve the digestion and absorption ability of beef cattle, promotes healthy growth, rapid weight gain, and a short slaughter cycle, effectively improving the economic benefits of beef cattle breeding; 3) The pressure-center type stirring device of the present invention adopts a composite structure of planetary stirring and pressure-center stirring. The planetary stirring component drives the stirrer to revolve around the central axis and rotate itself at the same time, realizing the three-dimensional mixing of materials and avoiding material caking or uneven local stirring. The pressure-center stirring component further extrudes and crushes the materials through the rotation of the spiral blades and crushing teeth on the central axis, strengthening the uniform mixing between the materials; 4) The spiral blades on the central axis of the present invention can push the mixed materials in the stirring shell downward to the bottom discharge port position, and further crush and extrude them with the crushing teeth rotating at high speed at the bottom. This strong extrusion and crushing process not only realizes the full contact between dry distiller's grains and fresh chicken manure, but also can effectively reduce the water content of fresh chicken manure, achieving the effect of uniform dry and wet consistency, creating favorable conditions for the subsequent fermentation link; 5) The vacuum feeding machine configured in the present invention can flexibly extend into any position inside the stirring shell for extraction through the adjustable structure of the telescopic bellows and sliding block. The vacuum negative-pressure type material taking avoids problems such as residual material accumulation and incomplete feeding that may occur in traditional gravity unloading, ensures a clean and thorough material taking process, improves the efficiency of the subsequent processing process and the utilization rate of materials; 6) The bottom of the open-type stirring shell of the present invention is set to be conical, which is beneficial for the materials to naturally concentrate in the central area of the shell under the action of gravity. At the same time, the height of the central cylinder is lower than the depth of the shell, ensuring that the height of the materials can cover the cylinder during the stirring process, effectively improving the conveying efficiency of the spiral blades on the central shaft. Under the synergistic effect of the two, the material flow is smoother, further improving the stirring and mixing effect; 7) The supporting legs at the bottom of the shell of the present invention adopt a three-group annular distribution form and are equipped with anchor fixing holes, greatly enhancing the stability of the equipment and avoiding resonance and shaking during the operation of the equipment. The bottom installation designs of the frame-shaped support and the centering motor also further lower the center of gravity of the equipment, improve the overall stability of the equipment, and ensure the reliability and operation safety of the equipment during long-term continuous operation.

[0020] The water content in the preliminary mixtures prepared by the above Examples 2 - 4 is 34% - 42%, and the water content in the feed obtained after fermentation is 18% - 22%, both meeting the requirements of feed manufacturing. Moreover, the organic matter content in the feed is higher than 55%, the crude protein content is higher than 20%, the crude fiber content is higher than 25%, and the cost price per ton of the feed is lower than 200 yuan, which is suitable for large - scale production.

[0021] Example 5 In Examples 1 - 4, a core - pressing type stirring device is used for stirring and mixing, enabling the dried distiller's grains to fully dry the fresh chicken manure and ensuring the consistency of the water content of the preliminary mixture.
