Problems solved by technology

The blades of the currently used corn harvesters are routinely made of low-quality cemented carbide, and some even use cast iron. During the production process, the corn husk is often incompletely broken due to incomplete cutting and remains wrapped in subsequent parts such as bearings. , resulting in downtime and often blade residue in the final product

Embodiment 1

[0015] A corn combine harvester comprises a fuselage, traveling wheels, a driver's cab, a harvesting device, an ear picking device, a peeling device and a straw chopping device.

[0016] The peeling device includes an upper conveyor belt, a lower conveyor belt, a knife seat and a cutter, wherein the cutter is made of cermet, and the chemical composition is calculated by weight percentage: TiC: 11.2%, ZrC: 3.68%, Cr 3 B 2 : 8.1%, Mo: 9.6%, C: 0.82%, Ni: 15%, RE: 0.08%, the balance is Co and unavoidable impurities, wherein the average particle size of the TiC phase is 0.3 μm, and the average particle size of the ZrC phase The diameter is 0.92μm, Cr 3 B 2 The average particle diameter of the phase was 0.16 μm.

Embodiment 2

[0018] The corn combine harvester described in embodiment 1, wherein said cutting knife undergoes the following steps after being formed.

[0019] (1) Place the formed semi-finished cutter into a resistance furnace to raise the temperature to 921°C, keep it warm for 28 minutes, and then put it into quenching oil for rapid cooling.

[0020] (2) Put the semi-finished product cooled to room temperature in step (1) into a cryogenic box to cool to -98°C, keep warm for 19 minutes, and return to room temperature by spraying high-pressure water; the water temperature of the water is 28°C.

[0021] (3) Put the semi-finished product obtained in step (2) into a tempering furnace and raise the temperature to 196°C, keep the temperature for 1.3 hours, then cool the furnace to room temperature to obtain the finished grinder blade.

Abstract

The invention relates to an agricultural machine, in particular to a corn combine. A material of a cutter blade in the peeling link is improved, and therefore the working efficiency of the agricultural machine is greatly improved.

Description

technical field [0001] The invention belongs to the field of agricultural machinery, in particular to a corn combine harvester, in particular to a cutting blade therein. Background technique [0002] The large-scale mechanization and modernization of agriculture is an inevitable trend, so the demand for agricultural machinery must be increasing, and because the target of agricultural machinery is not a standard part like industrial products, it will change with the climate Therefore, modern agricultural machinery is not like in previous years, as long as the cost is low and sufficient, but more and more attention is paid to the breadth of application, quality and durability. The blades of the currently used corn harvesters are routinely made of low-quality hard alloys, and some even use cast iron. During the production process, the corn husks are often incompletely broken due to incomplete cutting, leaving behind parts wrapped in bearings and other follow-up parts. on the m...
