Description

A kind of novel hard alloy matchet

Technical field

The utility model relates to matchet technical fields, and in particular to a kind of novel hard alloy matchet.

Background technique

The matchet of sugar-cane cutting machine is generally made of stainless steel, and cutting-tool's used life is low, when cutter itself uses one end Between the easily-deformable curling of rear blade, pull power when deformed matchet will increase cutting sugarcane, so that sugarcane damage is serious, make The cutting efficiency for obtaining sugarcane receives serious influence.

Utility model content

In view of the deficiencies of the prior art, the utility model provides a kind of cutting efficiency height, long service life, is conveniently replaceable Matchet.

The technical scheme adopted by the utility model to solve the technical problem is as follows:

A kind of novel hard alloy matchet, including circular beater plate and multiple matchets, multiple matchets are uniformly set It sets on circular beater plate, the matchet includes tool matrix and carbide bit, and the carbide bit is triangular form Structure, the both ends of the tool matrix are equipped with the accommodation groove of installation carbide bit, the carbide bit cutting edge to Outer its bottom surface of setting and an end face are welded in accommodation groove, and the tool matrix is stainless steel knife matrix, the tool matrix bottom Portion center is equipped with outwardly projecting rectangular locating piece, and the tool matrix be transversely provided with through tool matrix and The dormant bolt hole of locating piece.

In a kind of a kind of preferred embodiment of novel hard alloy matchet provided by the utility model, the circular knife Disk is equipped with cutter positioning mounting blocks, and the side of the cutter positioning mounting blocks is equipped with the groove to match with locating piece, described Through-hole corresponding with dormant bolt hole is equipped in groove, the tool matrix is fixed by bolts in groove.

In a kind of a kind of preferred embodiment of novel hard alloy matchet provided by the utility model, the hard is closed Golden cutter head is made of microlite high-density cemented carbide K10.

In a kind of a kind of preferred embodiment of novel hard alloy matchet provided by the utility model, the hard is closed The area of golden cutter head and accommodation groove welding surface is greater than the area of accommodation groove.

In a kind of a kind of preferred embodiment of novel hard alloy matchet provided by the utility model, with the hard Two connected inclined-planes of alloy cutter head cutting edge are provided with wear-resistant coating.

Compared with prior art, a kind of beneficial effect of novel hard alloy matchet provided by the utility model is: logical The carbide bit for crossing welding replaces pervious steel knife, improves cutting-tool's used life, reduces when cutting sugarcane Power is pulled, improves cutting efficiency, while the carbide bit of left and right ends can avoid because cutter is damaged without cutter more in work The case where changing.

Detailed description of the invention

It, below will be to required in embodiment description in order to illustrate more clearly of the technical scheme in the embodiment of the utility model Attached drawing to be used is briefly described, it should be apparent that, the accompanying drawings in the following description is only some realities of the utility model Example is applied, it for those of ordinary skill in the art, without creative efforts, can also be according to these attached drawings Obtain other attached drawings, in which:

Fig. 1 is a kind of novel hard alloy matchet structural schematic diagram provided by the utility model；

Fig. 2 is a kind of perspective view of novel hard alloy matchet provided by the utility model；

Fig. 3 is in Fig. 1 along the cross-sectional view in the direction A-A.

Specific embodiment

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describing, it is clear that described embodiment is only a part of the embodiment of the utility model, rather than whole Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work All other embodiment obtained, fall within the protection scope of the utility model.

It please refers to Fig.1 to Fig.3, a kind of novel hard alloy matchet, including circular beater plate 1 and multiple matchets 2, it is multiple The matchet 2 is uniformly arranged on circular beater plate 1, and the matchet 2 includes tool matrix 21 and carbide bit 22, institute Stating carbide bit 22 is triangular form structure, and the both ends of the tool matrix 21 are equipped with the accommodating of installation carbide bit 22 Slot 23, its bottom surface is arranged in 22 cutting edge of carbide bit outward and an end face is welded in accommodation groove 23, the cutter base Body 21 is stainless steel knife matrix, and 21 bottom centre position of tool matrix is equipped with outwardly projecting rectangular locating piece 24, and the tool matrix 21 is transversely provided with the dormant bolt hole 3 through tool matrix 21 and locating piece 24.

The circular beater plate 1 is equipped with cutter positioning mounting blocks 4, and the side of the cutter positioning mounting blocks 4 is equipped with and determines The groove 5 that position block 24 matches, the groove 5 is interior to be equipped with through-hole 6 corresponding with dormant bolt hole 3, the tool matrix 21 Groove 5 is fixed on by bolt 7.Setting in this way is not easy to loosen so that matchet 2 is installed closer with circular beater plate 1, when work More safety durable.

The carbide bit 22 is made of microlite high-density cemented carbide K10.Setting is so that matchet in this way Hardness is higher, and bending strength is higher, so that the service life of matchet greatly improves, rises to as many as 5 times of rigid knife.

The area of the carbide bit and accommodation groove welding surface is greater than the area of accommodation groove.Slightly larger than accommodation groove 22 Area can contact weld to avoid the sugarcane after cutting, and weld is avoided to loosen, so that carbide bit 22 and accommodating Slot 23 welds more secured.

Two inclined-planes being connected with 22 cutting edge of carbide bit are provided with wear-resistant coating.Setting is so that hard in this way Matter alloy cutter head 22 is more wear-resisting, increases the service life of carbide bit 22, so that matchet is more durable.

The above description is only the embodiments of the present invention, and therefore it does not limit the scope of the patent of the utility model, all Using equivalent structure or equivalent flow shift made by the utility model description, it is applied directly or indirectly in other phases The technical field of pass similarly includes within the scope of patent protection of the utility model.
