The invention belongs to the technical field of agricultural engineering cutting tool and discloses a novel saw tooth structure. The novel saw tooth structure is composed of cutting tooth edge saw teeth and V-shaped grooves (the saw teeth are arranged at the two ends of the V-shaped grooves). An original saw tooth shape and an arrangement mode are changed, and in the cutting process, cutting operation is conducted in a slidable cutting mode. Under the same cutting condition, the slidable cutting mode saves more labor relative to a wedging-tearing mode. A material is cut off through the special cutting tooth edge saw teeth so that the cutting surface is smooth, the probability of fracturing of cutting objects (long-stem-shaped crops or economic crops such as corn straw, sugarcane stems) due to failure of effective cutting in the cutting process is decreased. The novel saw tooth structure effectively enables the cutting face to be smooth, cutting force and cutting power consumption can be effective reduced, and the stem type of crops can be effectively prevented from fracturing when cut.
Description
technical field [0001] The invention belongs to the technical field of agricultural engineering cutting tools, and in particular relates to a sawtooth structure. Background technique [0002] In the cutting process of the existing saw blade sawtooth structure, the cutting material is first cut into and then torn, that is, in the cutting process, the cutting edge is firstly wedged into the material. Tear or peel, with the further movement of the saw teeth, the stripped material will be broken by the saw teeth, and the saw teeth will cut off or cut the material continuously to complete the cutting operation. However, such a cutting method will cause the cutting surface to be rough (caused by breaking the material), and the cutting force is too large due to the breaking of the material, so it is easy to develop fractures during the cutting process of high-stem crops (especially in the During the operation of agricultural machinery, it is more significantly affected by vibratio...
