Description
Technical Field
The utility model relates to a cutter technical field especially relates to a little C type straw returning machine flail knife of high strength.
Background
The straw returning machine is a soil preparation machine for uniformly mixing crushed crop straws with soil, a flail knife shaft provided with a flail knife is a core component of the straw returning machine, the performance of the flail knife shaft directly influences the crushing effect and the straw returning quality, and the main function of the straw returning machine is to drive the flail knife to rotate at a high speed to be matched with a fixed knife fixed on a housing to crush the crop straws fed by a feeding device. The flail knife of the existing straw returning machine has low strength, is easy to wear after being used for a period of time, needs frequent replacement or repair and has short service life.
SUMMERY OF THE UTILITY MODEL
The utility model aims at solving the defects of low strength and short service life of the flail knife of the straw returning machine in the prior art, and providing the flail knife of the high-strength small C-shaped straw returning machine.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
the utility model provides a little C type straw returning machine flail knife of high strength, includes the flail knife blade, the left side integrated into one piece of flail knife blade is provided with handle of a knife end button head, the up end of handle of a knife end button head runs through and is provided with the flail knife fixed orifices, the integrated into one piece of flail knife blade is provided with the flail knife intermediate plate, the both sides of flail knife intermediate plate are provided with the alloy cutting edge.
Preferably, the surface of the alloy blade is coated with a high-strength alloy coating, the alloy blade is C-shaped, and the bending radian of the C-shaped alloy blade is seventy degrees.
Preferably, the cutting edge angle of the alloy cutting edge is twenty degrees, and the edge thickness of the alloy cutting edge is 1.5 mm.
Preferably, the flail knife intermediate plate is an arc-shaped plate, and the bending angle of the flail knife intermediate plate is one hundred twenty degrees.
The utility model provides a pair of little C type straw returning machine flail knife of high strength, beneficial effect lies in: the high-strength small C-type straw returning machine flail knife has the advantages of being high in crushing capacity, high in speed, good in crushing effect and capable of flanging two side cutting edges, and the key is that high-strength alloy coating is carried out on the main crushing alloy cutting edges of the two side cutting edges of the flail knife by adopting a high-temperature hot melting technology, the usability of the flail knife of the novel high-strength small C-type straw returning machine is improved, after the high-strength alloy coating is carried out, the resistance in the process of crushing straws is reduced, the crushing speed is improved, the crushing effect is good, and the self-sharpening blade is provided.
