Disc-type cutting device of herbage reaping and flattening machine

Abstract

The invention discloses a disc-type cutting device of an herbage reaping and flattening machine. The disc-type cutting device comprises a body, driving motors, herbage poking poles and cutting blades,the driving motors are arranged at the top of the body, rotating shafts are arranged at bottoms the driving motors and fixedly welded to rotors of the driving motors, the herbage poking poles are arranged on upper surfaces of the rotating shafts, connection shafts are arranged at bottoms of the rotating shafts and are rotationally connected with the rotating shafts, the cutting blades are arranged on surfaces of the rotating shafts, the cutting blades and the rotating shafts are fixed through bolts, limiting blocks are welded onto surfaces of the rotating shafts, rotating grooves are formed in surfaces of the connection shafts, and the limiting blocks are positioned in the rotating grooves. The disc-type cutting device has the advantages that since the rotating grooves are formed in the surfaces of the connection shafts and the limiting blocks are arranged in the rotating grooves, the cutting blades can be rebounded when meeting hard objects or stones during rotation, rebounding positions of the cutting blades can be limited by the limiting blocks, rotating directions of the cutting blades are guaranteed, coercive cutting of the cutting blades is avoided, and the cutting blades are protected from damage.

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 ...
