Description
Technical Field
[0001] The utility model belongs to the technical field of animal husbandry, and in particular relates to a grass cutting device with a fixed-length feeding structure. Background Art
[0002] A grass-chopping device is a mechanical device used to cut long strips of grass into shorter segments. It is mainly used in animal husbandry, feed processing, agricultural production and other fields. This device cuts the grass through a high-speed rotating blade or a fixed knife, making it easier for the livestock to chew when feeding them. With the development and innovation of grass-chopping device technology, it is suitable for more and more livestock species, such as donkeys. Donkeys are herbivorous animals, and their main food sources include various grasses, crop straws, etc. In the process of donkey breeding, reasonable grass management and the use of grass-chopping devices can improve feed utilization and reduce feeding costs.
[0003] When the existing grass-chopping device is in use, the grass is usually transported to the grass-chopping device through a conveyor belt. However, due to the different lengths of grass, when the grass is cut by the cutting structure in the grass-chopping device, the inertia during cutting easily causes the tail end of the grass to curl upward. At this time, the user's palm needs to be in contact with the grass for a long time to limit the position, and then the grass can be fed into the cutting structure in the grass-chopping device for cutting and crushing. However, this limited contact not only easily causes the user's palm to be easily pulled by the suction force of the cutting structure, thereby easily causing the cutting structure to cause harm to the user, reducing the protection for the user, but also causes the residual grass to be easily adsorbed on the conveyor belt when the grass is transported, which is not convenient for cleaning. Therefore, we propose a grass-chopping device with a fixed-length feeding structure, which has the function of being easy to use and needs to be developed urgently. Utility Model Content

At this time, the user's palm needs to be in contact with the grass for a long time to limit the position, and then the grass can be fed into the cutting structure in the grass-chopping device for cutting and crushing. However, this limited contact not only easily causes the user's palm to be easily pulled by the suction force of the cutting structure, thereby easily causing the cutting structure to cause harm to the user, reducing the protection for the user, but also causes the residual grass to be easily adsorbed on the conveyor belt when the grass is transported, making it inconvenient to clean the technical problem.
