Abstract

The utility model provides a cane knife on a cutting cane machine of a pre-treatment apparatus in a sugarcane factory. The utility model is characterized in that a knifepoint part which is easily abraded and easily fractured is taken out, causing the width of the thinnest tail part of the cane knife to be 2 to 20 millimetric; the shock resistance of the cane knife is enhanced, and more tungsten carbide can be welded on the cane knife in a build-up way. Compared with cane knives in other sugar factories, the utility model which is impacted by inclusion foreign matters in sugarcane has the function of non-perishable breaking, and after the same built-up weld tungsten carbide treatment is carried, the utility model can enhance the abrasion resistance of the cane knife 1 to 4 times.

Description

Sugar refinery cane knives cane knife of no point of a knife

The utility model relates to a kind of cane sugar factory pre-processing device, particularly first, second of sugar refinery time sugarcane by the cane knife in the broken equipment cane knives.

Existing cane sugar factory generally all is divided into broken for the first time and broken two-stage fragmentation for the second time to the fragmentation of sugarcane.Disintegrating apparatus can be described as shredder, shredding machine, cane knives etc. according to the difference of the outer shape of the turning to of electric motor, cutter, generally is referred to as cane knives.The function of cane knives is exactly with the sugarcane fragmentation, makes its sugarcane silk that becomes the macrofiber shape, and at present the cane knives of cane sugar factory all are to rely on the cane knife of being installed to realize fragmentation to sugarcane.Because the high speed rotating of cane knives, and reason such as sugarcane hardness is bigger, make the cane knife wearing and tearing on the cane knives very fast, the point of a knife easy fracture.After cane knife wearing and tearing and the fracture, can make the hypofunction of cane knives, reduce the sugarcane degree of fragmentation, and then the sucrose extraction of influence back operation squeezing machine, the sugar part rate of recovery in whole sugar refinery reduced.For head it off, traditional method is a built-up welding wolfram varbide on original cane knife knife edge.But still have following 2 deficiencies: (1) cane knife point of a knife part area is very little, and acceptable built-up welding wolfram varbide seldom.And point of a knife is part of the force, and it is the fastest to wear and tear, and therefore, the method for built-up welding wolfram varbide does not solve the wear-resisting problem of point of a knife well; (2) the cane knife major part all is to use 45# steel or A3 steel to make, and its intensity is not very big, and when point of a knife was run into the harder objuct bodies such as steel wire that are mingled with in the sugarcane, point of a knife was easy to fracture, and the result can increase the distance between cane knife and the conveying belt, causes the consequence of Lou cutting sugarcane.

The purpose of this utility model provides a kind of modified version cane knife that can overcome the weak points such as easy to wear and easy fracture of cane knife in the existing cane knives.

The utility model is realized in following mode: modified version cane knives cane knife comprises cutter hub, the edge of a knife and the dovetail cutter groove that matches with the cane knives tool rest, be characterized in not having elongated sharp keen point of a knife, be that only to keep width be the 2-20 millimeter at cutter tail the thinnest place, the cutter tail is widened or the built-up welding wolfram varbide, and the length of whole cane knife is constant, and the knife edge that is used to cut sugarcane also meets sugar refinery processing requirement.

Cane knives cane knife of the present utility model is compared with existing cane knife, and its advantage is:

1. because cane knife does not have point of a knife, cutter tail broad, can the more wolfram varbide of built-up welding, shock proof ability strengthens, and has guaranteed rigidity.

2. wear resistance is strengthened, press sugar refinery test of 3300 tons of sugarcanes one day in Guangxi through the design people, experience two and press season, the cane knife wear resistance of the design's no point of a knife generally improves 1-4 doubly than the wear resistance that point of a knife is arranged, none fracture of 45 no point of a knife cane knifes on probation, and the fracture rate of the cane knife that point of a knife is arranged of contrast reaches more than 20%.

Manufacturing process with the basic identical of point of a knife arranged, do not increase operation, do not increase cost, the method that is installed on the cane knives also remains unchanged, but than the manufacturing that point of a knife is arranged with install safer.

Below in conjunction with accompanying drawing shape of the present utility model and structure are described:

Fig. 1 is the shape and the structure iron of no point of a knife cane knife.

See from figure: the cane knives cane knife comprises cutter hub 1, the edge of a knife 3 and dovetail cutter head, the no elongated sharp keen point of a knife in cutter tail 2 places (promptly near the edge of a knife 3 places), but can be wide a little or built-up welding wolfram varbide is arranged, the length of whole cane knife is constant, matches with original cane knife of cutting.

Claims (2)

1. sugar refinery cane knives cane knife comprises cutter hub (1), the edge of a knife (3) and dovetail cutter head (4), it is characterized in that the no point of a knife of cutter tail (2), and widens or the built-up welding wolfram varbide.

2. cane knives cane knife according to claim 1 is characterized in that the width at thin place of cutter tail (2) is the 2-20 millimeter.
