Disc type pasture harvesting and flattening machine cutting device

Abstract

The invention discloses a cutting device for a disc-type forage harvesting and flattening machine, which includes a body, a driving motor, a weed lever and a cutting knife. The top of the body is provided with a driving motor, and the lower part of the driving motor is provided with a rotating shaft. The shaft and the rotor of the motor are welded and fixed, the upper surface of the rotating shaft is provided with a weed lever, the lower part of the rotating shaft is provided with a connecting shaft, the connecting shaft is connected with the rotating shaft in rotation, and a cutting knife is provided on the surface of the rotating shaft. The cutting knife and the connecting shaft are fixed by bolts, the surface of the rotating shaft is welded with a limiting block, the surface of the connecting shaft is provided with a rotating groove, and the limiting block is located inside the rotating groove. Cutting device, the surface of the connecting shaft is provided with a rotation groove, and the limit block is placed in the rotation groove. When the cutting knife rotates and encounters a hard object or stone, it will rebound. The limit block restricts the rebound position of the cutting knife to ensure the direction of rotation of the cutting knife. , to prevent the cutting knife from forcibly cutting and causing damage to the cutting knife.

Description

technical field [0001] The invention relates to the technical field of forage cutting devices, in particular to a cutting device for a disc-type forage harvesting and flattening machine. Background technique [0002] With the development of animal husbandry, the number of herbivorous livestock such as cattle and sheep has increased, and the planting area of ​​pasture has also increased, especially the planting area of ​​high-nutrition, high-protein, economical forage-alfalfa grass has increased significantly . Alfalfa is known as the king of pasture due to its high quality and high protein. During the nutrient-rich period, alfalfa usually contains more than 70% moisture. Only during the nutrient-rich period of pasture, it can be quickly dehydrated and processed to maximize the maintenance of nutrients and safe storage. In order to effectively improve the feed intake and digestibility of materials, thereby increasing the commodity value of pasture, it is also convenient for ...
