Embodiment 1
[0068] A multi-serrated disc cutting blade, comprising a disc-shaped metal base 1 with a central hole 4, the outer circumference of the metal base 1 is provided with a number of evenly distributed cutting saw teeth 2, and each edge of the cutting saw teeth 2 is provided There are several cutting small sawtooths 3 evenly distributed, and the thickness of the tooth back of the cutting sawtooth 2 is greater than the thickness of the tooth tip;
[0069] The adjacent cutting saw teeth 2 have an angle of 15°, and the adjacent small cutting saw teeth have a pitch of 5 mm; the cutting saw teeth 2 have a tip angle of 15°, and the cutting small saw teeth 3 have a tip angle of 30°.
[0072] Step 1: Heat the steel plate of 80CrV2 high speed steel to 1100~1200°C, keep it warm at 900~800°C for 30~45 minutes, complete the primary annealing, and then place the steel plate after the primary anne...

Abstract
The invention discloses a multi-sawtooth disk cutting blade. The multi-sawtooth disk cutting blade comprises a disk-shaped metallic matrix with a center hole, wherein a plurality of cutting sawteeth which are uniformly distributed are arranged on the outer circumference of the metallic matrix, a plurality of small cutting sawteeth which are uniformly distributed are arranged at the edge of each cutting sawtooth, and the thickness of a tooth back of each cutting sawtooth is greater than that of a tooth point of each cutting sawtooth. According to the multi-sawtooth disk cutting blade, the cutting sawteeth are arranged on the disk-shaped metallic matrix, and the small cutting sawteeth are arranged on the cutting sawteeth, so that a cutting face formed by the small cutting sawteeth is much larger than that formed by only the cutting sawteeth during cutting of stalks; and meanwhile, sharp parts can also be formed on the small cutting sawteeth, so that plant stalks formed by plant fibers can be cut through the sharp parts under the condition that the cutting face cannot carry out complete cutting.
Description
technical field [0001] The invention relates to the field of agricultural machinery, in particular to a multi-serrated disc cutting blade. Background technique [0002] In modern agricultural production, the disc cutting part is an important part for harvesting stalk crops. In the prior art, the Chinese patent with the notification number CN202498268U is a disc cutting piece, which includes a disc-shaped metal base with a central hole. The outer circumference of the metal base is surrounded by a plurality of cutting sawtooths, the thickness of the tooth back of the cutting sawtooth is greater than the thickness of the tip, and the cutting sawtooth is evenly distributed along the outer circumference of the metal base. Chip removal grooves are formed between two adjacent cutting saw teeth, and a wear-resistant cutting layer is evenly welded on the surface of the cutting saw teeth. This disc cutting disc adopts cutting sawtooth, which can effectively improve the cutting effici...
