Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of forage processing equipment, in particular to a forage crushing device. BACKGROUND

[0002] Forage refers to the stem and leaf of herbaceous plants that can be used as feed for herbivorous animals, and is often referred to as pasture, which is a herbaceous plant specifically used for feeding livestock. They usually have characteristics such as vigorous growth, tender grass, high yield per unit area, and strong regenerative ability. These characteristics enable forage to be harvested multiple times a year, providing a sustainable source of feed for the livestock industry. Forage comes in a variety of types, including grasses such as timothy grass, wild grass, and fescue, as well as legumes such as alfalfa and clover. These pastures not only have good palatability, but also are rich in essential nutrients such as high-quality protein, vitamins, and minerals, which are crucial for promoting the healthy growth of livestock. It is not only an important focus for adjusting and optimizing agricultural structure, but also one of the key factors for ensuring national food security and food safety. Through scientific planting and management, the forage industry can significantly improve the overall efficiency of the planting industry, while also contributing to soil quality improvement and environmental protection. Before feeding forage, it needs to be crushed and cut into small pieces. Cutting forage increases its contact area with digestive fluids, thereby improving the animal's digestion and absorption rate of forage. The cut forage is easier for animals to chew and digest, reducing feed waste. For some animals such as sheep, cut forage is easier to eat, avoiding the picky eating phenomenon caused by long forage, and improving the utilization rate of forage.

[0003] Currently, forage crushing operations involve feeding bundled or chunky forage into a crushing box, where it is cut by a crushing knife. While this method can complete the crushing and cutting process, it also has the problem of water and impurities accumulating inside the forage during storage, which requires preliminary drying of the forage to prevent it from sticking to the crushing box due to excessive moisture.
