Further, the cutter head is fixed on by welding on the upper side of knife plate.
Further, several second slots vertical with mounting groove are additionally provided on the upper side of the knife plate, the installation is prominent
Block is equipped with the second projection cooperated with the second slot.
Further, the knife plate is equipped with the opening of rectangle, and the mounting groove is set on the horizontal section of opening.
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
The utility model is made of cutter head of hard alloy, and the hardness of hard alloy is 90HRA, general in the prior art
The hardness of logical knife is only 55-60HRC, improves the hardness of knife, using hard alloy high rigidity, high abrasion, cutting efficiency is fast etc.
Feature has the function that the crops such as high-speed cutting wheat, rice, and is set in mounting groove by installing projection, compares existing
Have and welded after directly docking cutter head with knife plate in technology, increases the binding force of cutter head and knife plate, it is therefore prevented that in cutting process
The occurrence of cutter head and knife plate weld cracking.

Specific embodiment
In order to clearly illustrate the technical characterstic of this programme, below by specific embodiment, and its attached drawing 1 to 6 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.
As shown in Figure 1, Figure 2, Figure 4 shows, a kind of harvester alloy knife of high-strength binding force, including knife plate 1 and cutter head 2, it is described
Cutter head 2 is made of hard alloy, and the hardness of hard alloy is 90HRA, and the hardness of regular knife is only 55- in the prior art
60HRC improves the hardness of knife, and using hard alloy high rigidity, high abrasion, it is small that the features such as cutting efficiency is fast reaches high-speed cutting
The effect of the crops such as wheat, rice, the knife plate 1 are equipped with mounting hole 11, are pacified by the cutter that mounting hole is installed on harvester
Holding position, as shown in Figure 2, Figure 4 shows, the first embodiment, the upper side of the knife plate 1 are equipped with the mounting groove 12 of a strip,
The bottom end of the cutter head 2 is equipped with the installation projection 21 of strip, and the installation projection 21 is set in mounting groove 12, the knife
First 2 with installation projection 21 pass through fusion cast process, during actual use, the higher damaged condition of the hardness of cutter head almost without, but
It is cutter head often occur to cause crushing knife to damage with knife plate weld cracking, is since cutter head is by the front and back for being parallel to welding surface
Weld seam easily disconnects after the cross force in direction, and the utility model overcomes weld cracking by the structure that projection and mounting groove cooperate
The problem of, the cross force in the front-back direction that cutter head is subject to is overcome by projection and mounting groove, the utility model compares existing
It is welded after directly docking cutter head with knife plate in technology, increases the binding force of cutter head and knife plate, it is therefore prevented that knife in cutting process
The occurrence of head is with knife plate weld cracking.
Further, the cutter head 2 is fixed on by welding on the upper side of knife plate 1, welding manner herein
For soldering, it is combined together cutter head closely with knife plate.
As shown in Figure 5, Figure 6, second of embodiment, the difference with the first embodiment be, the upper side of the knife plate 1
On be additionally provided with several second slots 13 vertical with mounting groove 12, the second slot 13 and the first slot form the slot of cross, further enhance
Stability of the cutter head on knife plate, increases bonded area, and the external force for the left and right directions that cutter head can be overcome to be subject to, the peace
Dress projection 21 is equipped with the second projection 22 cooperated with the second slot 13.
As shown in figure 3, the knife plate 1 is equipped with the opening 14 of rectangle, the mounting groove 12 is set to the level of opening 14
It on section, compares and is directly mounted at the upper end of knife plate 1, the left side of cutter head is in conjunction with the vertical section of knife plate opening 14, to knife
Head plays a protective role.
A kind of harvester alloy knife of high-strength binding force provided by the utility model, cutter head wear small in 5000 mu, cut
Careless thin, Lysimachia sikokiana effect is good, and not stifled grass alleviates the resistance of harvester, and machine crushing is zero load, enhances the work that tooth is got rid of in roller
Make efficiency, greatly improve the percentage of thresh of grain, per mu yield dramatically increases.The utility model is all used in moving knife and stationary knife
In the case where alloy knife, the steel knife harvesting in the prior art that compares can save the oily cost of 2-3 member per acre.
Although above-mentioned be described in conjunction with specific embodiment of the attached drawing to utility model, not to the utility model
The limitation of protection scope, based on the technical solution of the present invention, those skilled in the art do not need to pay creativeness
The various modifications or changes that working can make are still within the scope of the present invention.
