A kind of cutting tool for silage machine, cutting disc and silage machine

technical field

The disclosure relates to the technical field of silage harvesting machines, in particular to a cutting tool for a silage machine, a cutting disc and a silage machine.

Background technique

With the implementation of my country's grain-to-forage policy, the pasture industry will have a great development. Silage corn is the key direction of grain-to-forage reform, and it is expected to reach 25 million mu in 2020. Although my country's silage equipment has developed greatly in recent years, it still cannot meet the needs of the continuous expansion of the forage industry. Green fodder harvesting is an operation item that requires high timeliness of operation. The quality of the cutting tool directly affects the operation stability, harvesting efficiency and energy consumption of the silage machine.

Existing cutting knives all adopt a disc-shaped structure with a cutting knife at the end, and the material is generally manganese steel or high-carbon steel. The production cost is relatively high, the quality is difficult to control, the wear resistance of the knives is relatively poor, and it is difficult to keep the knives for a long time. sharp.

The working principle of the cutting tool of the present disclosure is:

A block-shaped blade is set at the sawtooth tip of the sawtooth structure of the cutting blade, and the hardness of the blade is greater than the strength of the cutting blade. In this way, there is a difference in hardness between the cutting blade and the blade. When working for a long time, the cutting blade wears faster and the blade Wears slowly and naturally forms the edge of the cutting part, thus achieving self-sharpening.

As a further technical solution, the blade is fixedly connected with the cutting body as a whole.

As a further technical solution, the thickness of the blade is smaller than the thickness of the sawtooth structure.

The second object of the present disclosure is to provide a cutting cutterhead for a silage machine, which includes a cutterhead body, the cutterhead body is a disc-shaped structure, and a plurality of cutting knives as described above are fixed on the outer periphery of the disc-shaped structure.

As a further technical solution, a plurality of cutting knives are adjacently arranged in sequence on the periphery of the cutter head body.

As a further technical solution, a plurality of the cutting knives form an annular structure.

As a further technical solution, a mowing board is fixedly arranged at the bottom of the cutting tool.

As a further technical solution, the mowing board has a bent structure, and the distance between the bent structure and the inner side of the cutting tool is smaller than the distance between the bent structure and the outer side of the cutting tool.

As a further technical solution, a pressing plate is arranged adjacent to the bottom of the adjacent part of the cutting tool, and the pressing plate is fixedly connected with the cutter head body.

A third inventive object of the present disclosure proposes a silage machine comprising a cutting disc as described above.
