Knife, improves the hardness of cutter head, to accelerate harvesting speed and improve harvesting quality, and efficiently solves because getting to foreign matter
Caused by cutter head the problem of bursting apart.
The technical solution of the utility model solution technical problem are as follows:
A kind of harvester the hard alloy crushing knife for being conducive to protection cutter head, including knife plate and cutter head, the cutter head welding
In the right end of the upper side of knife plate, the cutter head is made of hard alloy, and the lower right corner of the knife plate forms after being removed and lacks
Mouthful, the wide a of the notch is the 1/2 to 1/4 of the wide b of knife plate, and the long c of the notch is equal with the length of cutter head.
Further, the knife plate is made of steel plate.
Further, the upper side of the knife plate is equipped with the mounting groove of a strip, and the bottom end of the cutter head is equipped with length
The installation projection of bar shaped, the installation projection are set in mounting groove.
Further, the opening of rectangle is equipped at the upper right corner of the knife plate, the mounting groove is set to the water of opening
On flat section.
Further, the top of the cutter head and the top of knife plate are concordant.
The effect provided in utility model content is only the effect of embodiment, rather than whole effects that utility model is all
Fruit, a technical solution in above-mentioned technical proposal have the following advantages that or the utility model has the advantages that
1, the utility model is made of cutter head of hard alloy, and the hardness of hard alloy is 90HRA, in the prior art
The hardness of regular knife is only 55-60HRC, improves the hardness of knife, and using hard alloy high rigidity, high abrasion, cutting efficiency is fast
The features such as have the function that the crops such as high-speed cutting wheat, rice.
2, since the hardness of cutter head is high, poor toughness, when cutter head gets to hard foreign matter, cutter head easily bursts apart, this is practical
The lower right corner of novel knife plate forms notch after being removed, the wide a of the notch is the 1/2 to 1/4 of the wide b of knife plate, the notch
Long c is equal with the length of cutter head, by the way that notch is arranged, increases the deflection of knife plate, is set to the cutter head above notch and is encountering
When foreign matter, knife plate deforms, and plays the role of buffering, to efficiently solve because of cutter head caused by getting to hard foreign matter
The problem of fracture.
3, the utility model is set in slot by installing projection, relatively than in the prior art directly by cutter head and knife plate
It is welded after two plane docking, increases the binding force of cutter head and knife plate, it is therefore prevented that cutter head receives horizontal direction in cutting process
External force caused by weld cracking the occurrence of.
4, the utility model is by the way that in opening of the upper end of knife plate equipped with rectangle, the cutter head is arranged by welding
It is directly mounted at the upper end of knife plate in comparing on the horizontal section of opening, the vertical section of the side of cutter head and knife plate opening
In conjunction with playing a protective role to cutter head.

Specific embodiment
In order to clearly illustrate the technical characterstic of this programme, below by specific embodiment, and its attached drawing 1 to 4 is combined,
The utility model is elaborated.Following disclosure provide many different embodiments or example be used to realize it is practical
Novel different structure.In order to simplify the disclosure of the utility model, hereinafter the component of specific examples and setting are described.
In addition, the utility model can in different examples repeat reference numerals and/or letter.This repetition is in order to simplified and clear
Purpose, itself do not indicate discussed various embodiments and/or setting between relationship.It should be noted that being schemed in the accompanying drawings
The component shown is not drawn necessarily to scale.The description to known assemblies and treatment technology and process is omitted to keep away in the utility model
Exempt to be unnecessarily limiting the utility model.
A kind of harvester the hard alloy crushing knife for being conducive to protection cutter head, including knife plate 1 and cutter head 2, the weldering of cutter head 2
It is connected to the right end of the upper side of knife plate 1, the mode of welding is using soldering, and the cutter head 2 is made of hard alloy, hard alloy
Hardness be 90HRA, the hardness of regular knife is only 55-60HRC in the prior art, improves the hardness of knife, utilizes hard alloy
