Cutting knife climbing rod with unchanged climbing angle for rubber tree tapping machine

Abstract

The invention provides a cutting knife climbing rod with unchanged climbing angle for a rubber tree tapping machine. One end of a cutting knife climbing rod body is connected with a coupler arranged on an output shaft of a motor I, the motor I is fixed to a supporting pipe, the cutting knife climbing rod body penetrates through a gear variable stroke mechanism arranged on a knife rest, the cutting knife climbing rod body rotates to drive the gear variable stroke mechanism to ascend and descend, a knife head ascends and descends along with the gear variable stroke mechanism, the supporting pipe penetrates through the knife rest, one end of the supporting pipe is fixed to a sliding block I, the other end of the supporting pipe is fixed to a sliding block II, arc-shaped guide rails I and arc-shaped guide rails II are arranged in pairs in the vertical direction, the cutting knife climbing rod body is round, equal-pitch climbing lines are arranged on the outer circle face of the cutting knife climbing rod body, the climbing lines are obliquely arranged, the included angle between the climbing lines and the horizontal plane ranges from 5 degrees to 60 degrees, a cutting knife is arranged on the gear variable stroke mechanism, the cutting knife climbing rod body and the knife rest move relatively, the gear variable stroke mechanism is arranged on the knife rest, the motion trail of the cutting knife is a climbing line with a constant climbing angle, and the constant climbing angle of the cutting knife means that the included angle between the tangent line of each point on the climbing line and the horizontal line is a fixed value.

Description

technical field [0001] The invention belongs to the field of economic forests, and relates to a variable-diameter clamping and girdling tool, in particular to a cutting knife climbing rod used for rubber tree tapping machines with constant climbing angles. Background technique [0002] China is the fifth largest rubber-producing country and the largest rubber consumer in the world. Rubber trees are evergreen trees that grow in low-latitude tropical regions near the equator. They have taproot systems, unisexual flowers and monoecious plants, and secrete milky sap. There are more than 2,000 varieties of rubber trees in the world that can produce natural rubber. Rubber trees are mainly produced in the western region of Mara Mountain in the Amazon River Basin of Brazil. They are now distributed in more than 40 countries and regions such as Asia, Oceania, and Latin America. It is estimated that there are 5 to 6 billion adult rubber trees over 8 years old. Asia is mainly distribut...

Problems solved by technology

[0003] The current rubber tapping machine is a manual hand-held cutter to cut the bark of the rubber tree. It needs to be tapped at 2 to 5 am every day. During this time period, rubber is tapped at the same time, which requires a large amount of labor, concentrated labor time, and low efficiency.
