Technical Field
The utility model relates to the technical field of agricultural machinery, concretely relates to a cutter for agricultural machinery.
Background
A tool is a tool used for cutting machining in machine manufacturing, and is also called a cutting tool. Most knives are machine, but also hand-held. Since tools used in machine manufacturing are basically used for cutting objects, "tools" are generally understood to be cutting tools. The prior cutter is widely applied in the agricultural field, such as a common ploughshare for ploughing, a mower for mowing, a harvester for grain harvesting and the like. However, in the working process of the harvester, the cutter is gradually abraded due to the fact that the straw rubs against the cutter when being crushed, and the working efficiency of the agricultural machine is reduced.
At present, domestic agricultural cutters are mainly made of single metal materials, and the domestic cutters generally have the problems of low hardness and wear resistance and short service life, and can not be used continuously due to serious abrasion; the damage of the cutter is mostly concentrated at the position of the cutting edge, and the phenomena of passivation, serious abrasion, even notch and the like often occur at the position of the cutting edge.
In order to solve the problems, a high-hardness cladding layer is arranged on one surface of the cutting edge in the prior art, and the hardness of the cladding layer is higher than that of the metal of the cutter, so that the effect of self-grinding of the cutting edge is realized in the using process of the cutter. But because the cladding layer directly melts the setting at the one side whole cladding of cutting edge, can produce the friction with the cutting object when the cutter is at cutting process cladding layer, frictional force when not only leading to the cutting increases, and along with the live time of cutter, the cladding layer still produces whole the droing easily, leads to the cutter wearability to reduce.
