Abstract

The utility model relates to a rubber blade which comprises a cutter body of an ordinary steel product and a shank installed at the tail part of the cutter body. The rubber blade is characterized in that a cutter head made of wear-resistant steel is connected at the end of the cutter body of the ordinary steel product. The utility model not only overcomes the defects of the common steel cutting tool with stubbed cutting edge, low wear resistance, easy dulling, low operating efficiency, large work load of knife sharpening, and the like, but also overcomes the defects of the all-wear-resistant steel cutting tool with high waste of the high-quality steel, high cost, and the like simultaneously, the rubber workers can finish rubber cutting task only through one rubber blade during the rubber cutting process, and the blade is not required to be sharpened every day, therefore, the operating efficiency is effectively improved, and meanwhile, the labor intensity of the rubber workers is reduced.

Description

A kind of rubber tapping knife

Technical field

The utility model relates to a kind of rubber tapping knife, and especially a kind of cutter that cuts rubber belongs to crops harvesting apparatus technical field.

Background technology

Rubber tapping knife is mainly used to gather in rubber, is the instrument that the rubber workman must use when tapping rubber, and therefore, the quality of rubber tapping knife quality not only directly affects the operating efficiency of rubber tapping, also influences rubber worker's labour intensity.The rubber tapping knife that uses is made by single common iron at present, the intensity of its blade is very limited, use was less than one day, just blunt and unrenewable because of cutter, so must being equipped with rubber tapping knife more when harvesting rubber, the rubber worker just can finish darg, not only carry inconvenience, and the sharpening workload is also very big.If but the rubber tapping knife that has adopted steel to make is only used the cutter head part during owing to rubber tapping, remainder then can only use as handle of a knife, thus caused the waste of steel again, and the cost height, the rubber worker is difficult to accept.Therefore, be necessary fully prior art is improved.

Summary of the invention

For overcoming existing rubber tapping knife above shortcomings, the utility model provides a kind of and can will use the best steel to make the knife's edge, and can not cause waste again, and can increase work efficiency, and alleviates the rubber tapping knife of labor strength.

The utility model is finished by following technical proposal: a kind of rubber tapping knife, comprise the cutter hub of common iron, and be installed in the handle of a knife of cutter hub afterbody, it is characterized in that being connected with the cutter head of wear-resisting steel in the cutter hub termination of common iron.

The cutter head of described wear-resisting steel is connected by brazing on the cutter hub of common iron, to keep the sharp of blade, alleviates the sharpening workload, has saved the steel consumption.

The cutter head shape of described wear-resisting steel and the cutter hub shape of common iron adapt, so that both are integrally welded.

The utility model compared with prior art has following advantage and effect: adopt such scheme, both solved blade that the common iron cutter exists not cutting edge of a knife or a sword get, not wear-resisting, blunt easily, inefficiency, the big deficiency that waits of sharpening workload, the good steel waste that has solved complete wear-resisting steel cutter existence simultaneously again is big, the high deficiency of cost, the rubber worker only need be with a rubber tapping knife can finish the rubber tapping task when rubber tapping, and do not need all whet a knife every day, effectively increase work efficiency, reduce glue worker's labour intensity simultaneously.

Embodiment

Below in conjunction with accompanying drawing the utility model is described further, is not limited thereto but hold within the utility model.

The rubber tapping knife that the utility model provides, the cutter hub 4 that comprises common iron, be installed in the handle of a knife 5 of cutter hub 4 afterbodys, wherein be connected with the cutter head 2 of wear-resisting steel in cutter hub 4 terminations of common iron, the end of cutter head 2 is a cutting edge 1, and cutter head 2 usefulness copper 3 welderings (promptly 3 are brazed seam) of wear-resisting steel are connected on the cutter hub 4 of common iron, to keep the sharp of blade 1, alleviate the sharpening workload, saved the steel consumption.Cutter head 2 shapes of wear-resisting steel and cutter hub 4 shapes of common iron adapt, so that both are integrally welded.

Claims

1, a kind of rubber tapping knife comprises the cutter hub of common iron, is installed in the handle of a knife of cutter hub afterbody, it is characterized in that being connected with in the cutter hub end of common iron the cutter head of wear-resisting steel.

2, rubber tapping knife according to claim 1 is characterized in that the cutter head of described wear-resisting steel is connected on the cutter hub of common iron by brazing.
