Description

Rubber tapping cutter for rubber trees

Technical Field

The utility model relates to the technical field of natural rubber tapping, in particular to a rubber tapping cutter for a rubber tree.

Background

Natural rubber is an important equipment material in various countries, the economic benefit of the rubber trees is derived from the yield of latex obtained by rubber tapping, and how to simply and efficiently extract latex from the rubber trees is a problem which is urgently needed to be solved by the rubber industry. The natural rubber is obtained by cutting off the inner latex tube of the rubber tree through a rubber cutting tool, the rubber tree can be cut off for thirty to forty years continuously from planting to meeting the cutting requirement, 280 days of the rubber tree meeting the cutting requirement can be cut off in one year, and each tree needs to be cut for 110 times, and is cut for as much as 2 to 3 days. As the latex tubes in the bark of the rubber tree spirally rise from left to right at an angle of 3-50 degrees with the central axis of the trunk, in order to cut more latex tubes and improve the yield, the slope of a tapping line is 25-30% during tapping, the tapping line is inclined from left to right, and a certain tapping depth and a certain cutting thickness are controlled within the thickness of the bark to perform tapping operation.

Rubber tapping is an important link in rubber production, and is also a complex and delicate work with strong technical performance, the quality of a rubber tapping technology directly influences the yield of rubber, and a rubber tapping knife is a special tool for tapping latex from a rubber tree and is an important natural rubber production tool.

The earliest tapping does not teach a method, a method of drying and fishing is often adopted, and the normal growth of the rubber tree is seriously damaged by cutting the rubber tree too deeply by a knife or even cutting the rubber tree by a knife during tapping. In 1889, the main rendrei of the singapore rubber park began to adopt a bone-shaped and V-shaped secant method, a continuous repeated rubber tapping method which does not damage and form layers on the original secant is created, the sustainable yield of the rubber tree is improved, the rubber tapping method and the cutter are continuously developed in the following 120 years, the rubber tapping knife which is commonly used at home and abroad at present mainly comprises a traditional pushing type and a pulling type, and the rubber tapping knife which is widely used in China is the traditional pushing type. The traditional tapping knife and the using method are difficult to control the depth and thickness of tapping, the xylem of a rubber tree is very easy to cut, the depth and thickness of a cutting surface are different, the quality of a tapping technology directly affects the yield and the health condition of the rubber tree, skilled and professional tapping workers are required to master the tapping knife by personal technology, the artificial difference is very large, requirements on beginners or technologists with low technology are high, tapping can be performed after all the tapping knives are qualified, one month or more is needed for cultivating one skilled tapping worker, and a large amount of technical training cost is required to be invested.

With the continuous low market price of natural rubber, the rubber tapping mode is slowly renovated and has low efficiency, the rubber tapping work is more and more unattractive, and the rubber tapping workers are generally aged at present. In order to better improve the rubber tapping efficiency and reduce the threshold of the rubber tapping technology, an electric rubber tapping knife, a mechanical rubber tapping machine and the like are also appeared on the market at present, for example, a moving mechanism of a knife rest assembly is disclosed in the utility model patent with the patent application number of CN202021468030.2 (with the publication number of CN213427479U), which comprises an upper semi-annular frame, a lower semi-annular frame, a spiral guide rail, a connecting rod and a moving frame, wherein the two ends of the upper semi-annular frame are respectively connected with the two ends of the lower semi-annular frame through the connecting rod, the upper semi-annular frame and the lower semi-annular frame are fixed on a rubber tree, the spiral guide rail is respectively movably connected with the connecting rods at the two ends, the moving frame is in sliding connection with the spiral guide rail, the moving frame is provided with a driving motor, the driving motor is provided with a winding drum, the first end of a first pull rope and a second pull rope is fixed on the upper end of the spiral guide rail, the second pull rope is fixed at the lower end of the spiral guide rail. The utility model provides a moving mechanism of a tool rest assembly, which has a simple structure, does not need exposed gear parts and is not easy to be clamped by branches.

However, the tapping machine including the above-mentioned solution has invisibly increased tapping cost and maintenance work of the machine, and has not been popularized due to inconvenient carrying, poor use experience, poor practicability, and the like.
