Meanwhile, xinjiang is a great agricultural province, and the main crop straw resources are rich, so that the development of the cattle and sheep industry can be supported and ensured.
The three-large straw feed of corn straw, wheat straw and rice straw is a main coarse feed for breeding cattle and sheep in China and Xinjiang, and is also an important guarantee for the great development of grain-saving animal husbandry in China and Xinjiang. The increase of the livestock breeding demand for straw resources promotes the development of the straw square bundle mechanized technology, and Xinjiang corn straw, wheat straw and straw are generally recycled by adopting a bundling machine and stored in a square bundle mode.
In the large-scale cattle and sheep cultivation of China and Xinjiang, corn stalks, wheat stalks and square bundle stalks are crushed mainly by a hay cutter and a hammer crusher. The hay cutter technology is mature, and the types of machine types are more. The hammer mill can be used for feed and forage, and the technical level of feed crushing is achieved to the international advanced technical level. The hay cutter and hammer crusher are mainly suitable for crushing hard stalk. The main problems exist when the device is used for crushing square bundles of straws: firstly, the straw is manually scattered and fed when square baled, and the problems of low productivity, high energy consumption, high labor intensity and poor operation safety are generally existed. Secondly, the processing quality is poor. The lengths of corn stalks, wheat stalks and rice straws processed by the hay cutter are generally more than 3 cm, about 5 cm is a lot, and some of the corn stalks, the wheat stalks and the rice straws are longer, so that the beef cattle cultivation requirements can be met, but the optimal length of the mutton sheep is difficult to be less than 2 cm. Thirdly, the straws are wet and dry, hard and soft, and thick and thin, and the existing machine cannot be used for finely dividing and processing, so that the processing efficiency is low because of being too thick and too hard, or the energy consumption is high because of processing the thin and soft straws by a high-power machine, and the energy is wasted.
Therefore, how to effectively improve the crushing efficiency and the processing quality of square bundles of straws and subdivide the processed objects and the crushed feed specifications so as to reduce the energy consumption of machines and the labor intensity of workers is a technical problem of forage processing in the large-scale cultivation of cattle and sheep at the present stage. Therefore, on the basis of the prior cutting knife and hammer sheet crushing characteristics, the invention starts with the design method and experiment of the secondary stirring knife, the cutting knife, the hammer knife and the combined mechanism thereof, develops the research of the direct feeding square bundle straw crushing mechanism, and provides a series of feed processing machines aiming at the specialized large-scale production requirements of different straws and different quality requirements.
