Description
Technical Field
The invention relates to a tapping cutter, in particular to a tapping cutter with multiple cutting action surfaces in both end face cutting and side face cutting modes.
Background
Natural rubber is an important strategic resource and is widely applied to military and national defense. At present, natural rubber production mainly depends on manual rubber tapping of manpower, a traditional V-shaped rubber tapping knife is used for cutting a rubber tree, rubber tapping work can only be carried out in the morning, the working strength is high, a worker is required to have rich experience, rough bark, sand bark and partial cortex are accurately cut, and the trees are prevented from being cut to form a cambium to be injured. Meanwhile, the operation efficiency of workers is not high, the time for cutting one tree exceeds 30s, the cost is overhigh due to low efficiency, the number of rubber tapping workers is less and less, the resources of the rubber tree cannot be effectively utilized, and the rubber yield is greatly influenced.
The rubber cutting process is quite complex: the surface bark of the rubber tree is divided into 5 layers, and the rough bark, the sand bark, the yellow bark, the water sac bark and the cambium are sequentially arranged from outside to inside. The latex tube mainly producing the rubber function in the rubber tree is arranged on the clausena lansium layer, the clausena lansium layer is extremely close to the formation layer, and the cutting is too shallow, so that the rubber yield is small, and the cutting depth needs to be accurately controlled. ② the glue solution flows to a collecting container along the cutting surface after exuding from the milk duct. The surface appearance of the cutting surface influences the flowing state of the glue solution, the glue solution flowing can be blocked by the unsmooth surface of the cutting surface, the cutting fluid can be caused to run off from the side surface due to the unsmooth surface of the edge, and therefore the smoothness and the smoothness of the cutting surface are required to be guaranteed. Thirdly, the cutting period of the rubber tree is once every two days or once every three days, along with the generation of new protective substances on a cut surface, the seepage of glue liquid is gradually stopped, and finally a layer of thick jelly is formed on the surface. The invention patent CN105075799A discloses a rotary cutter body of a rubber electric tapping cutter, which consists of a cylindrical cutter body, an axial spiral blade group, a radial spiral blade group and a motor shaft fixing hole, and can cut rubber barks longitudinally and transversely, but the cutter structure of the rotary cutter body is difficult to control tapping width well, and the side surface has no cutting edge, so that the cutting quality with the side surface of a rubber tree is difficult to ensure; the invention patent CN1010558198A discloses a novel tapping cutter comprising a cutter handle, a straight flute milling cutter and an elliptical flute milling cutter, wherein the front end of the milling cutter is provided with a limiting ball for limiting the depth of the milling cutter entering a trunk. But the rubber tapping width cannot be well controlled by the arc groove structure, the rubber layer with enough depth is difficult to cut, the strength of an overlarge wedge angle is excessive, the wood fiber is difficult to cut due to insufficient sharpness, the coaxiality is difficult to ensure when the load is transmitted by threaded connection, and the rubber layer is difficult to disassemble due to the action of cutting force in clamping; the invention discloses an electric rubber tapping knife and a rotary cutter head thereof, and the electric rubber tapping knife comprises a knife handle with a knife connecting end and a knife mounting end, and a knife body arranged at the knife handle mounting end, wherein the knife body is provided with a knife edge, the knife edge comprises a first knife edge, a second knife edge and a third knife edge which are sequentially connected, push cutting or pull cutting can be realized, but the direction of a cutting axis is the same as the axis of a tree, so that a motor spindle and a bark can interfere, the inclined rotating shaft can lead a cutting surface to incline outwards so that glue solution flows out from the side surface, the cutting surface is an arc surface, the removal of wood fibers is not facilitated, chips cannot be discharged towards the knife handle direction, the chips are easily accumulated at the knife head to affect cutting, the design of a square clamping head causes large processing difficulty and difficult limiting in the axis direction, and meanwhile, abrasion in the working process generates gaps to affect the rotating precision.
In summary, the prior art disclosed in the above patent has the following disadvantages: the existing tapping cutter is mostly formed by modifying a milling cutter, and the difference of cutting characteristics caused by the tissue difference of tree fibers and metal materials is not considered; secondly, the existing tapping cutter has unreasonable angle parameter design, the cutting surface is not smooth enough, and the direction of the cutting surface is not beneficial to flowing and collecting glue solution; most clamping structures of the existing tapping cutters are unreasonable in design, low in coaxiality, poor in disassembly and assembly performance and high in machining difficulty; the existing rubber tapping cutter is mostly integrated, the whole cutter needs to be replaced after one cutting edge is damaged, the cost is increased, the waste is caused, and the angle and the mounting structure of the cutter cannot be changed in due time according to different rubber flowing states caused by environmental changes such as temperature, humidity, seasons and the like; most of the existing rubber tapping cutters only have side cutting edges, and the cutting edges without blunt end surfaces of the cutters damage the side surfaces of the trunk, which is not beneficial to sustainable production.
Therefore, there is a need for an electric tapping knife that can tap rubber trees with high efficiency and high quality. A smooth cutting plane can be obtained during cutting, and the cutting surface has a certain inclination angle, so that the glue solution can flow out conveniently; the cutting scraps can be smoothly discharged towards the direction of the cutter handle; the cutting width can be controlled, and the side surface of the trunk is not damaged; the clamping is convenient and reliable, and the universality is strong.
