Cutting blade for rotary cutting rubber mining machine

Abstract

The invention discloses a rotary-cut type cutting blade for a gum gathering machine. The rotary-cut type cutting blade comprises a first blade and a second blade, one end of the first blade is a rotary end synchronously connected with a spindle of the gum gathering machine, the other end of the first blade is a free end, the second blade extends towards the upside from the free end of the first blade, the free end of the first blade has a convex part which protrudes out of the second blade, and the rotary radius of the convex part is larger than the rotary radius of the second blade. Compared with the prior art, the rotary-cut type cutting blade for the gum gathering machine is capable of improving the gum gathering efficiency, easy to operate, capable of alleviating the eyesight, vigor and physical power consumption of a gum gathering worker, good for alleviating the labor intensity, capable of guaranteeing the large gum output of a rubber tree, and capable of effectively treating with the damage of diseases, pests, cold current and the like to the fresh cut surface of the rubber tree after gathering gum and reducing the time for restoring the rubber tree bark to the gum gathering required thickness, and the rotary-cut type cutting blade for the gum gathering machine has economical benefit and social benefit.

Description

technical field [0001] The invention relates to a cutting blade, in particular to a cutting blade for a rotary cutting type rubber harvester. Background technique [0002] Natural rubber, together with steel, petroleum, and coal, is called the four major industrial raw materials. It is an important raw material for the development of the national economy, and an important strategic material and industrial raw material for national defense. [0003] Rubber mining is an important link in the production of natural rubber. It is a delicate and highly technical manual operation. The level of its level directly affects the output and sustainable production of rubber tree latex. Compared with a good rubber picker and a poor rubber picker, the output difference between the two can reach 20% under the same conditions. [0004] The traditional rubber picking method is done manually. Specifically, the rubber picking workers use a rubber picking knife to cut grooves on the bark of the ...

Problems solved by technology

[0007] In addition, there is also a rubber harvesting method that uses the machine to drive the cutter to rotate to cut the bark, and uses the spindle of the rubber harvester to drive the cutter to rotate to cut the bark. This cutting method is roughly the same as the above manual cutting method, only using The machine drives the manual operation. Although the efficiency of rubber mining and the reduction of labor costs have been greatly improved, there is still the problem of damaging the bark fault tissue and resulting in low rubber output from the rubber tree in the later stage.
