Problems solved by technology

[0012] Severe wear will be caused on the inner surface of the connecting unit, especially in the opposite end area where the adjacent chain broken connecting units interface with each other
[0013] As a result of the above wear and tear, the slinger chain must be replaced periodically, and replacement of the slinger chain results in high capital expenditure and consequential loss of productivity
Therefore, due to its structure, size and other reasons, the elliptical chain has high cost and unsatisfactory working effect.

Abstract

The invention provides a high-strength trapezoid chain and a manufacturing method thereof. The chain comprises chain links connected in sequence. The chain is characterized in that the chain links are isosceles trapezoid chain links, each chain link unit is formed by four shin portions and four bending angle portions positioned at two ends of the shin portions, the shin portions and the bending angle portions form an internal space of a connecting unit, and the two adjacent chain links are mutually buckled to each other at the bending angle portions. According to the high-strength trapezoid chain and the manufacturing method thereof, the trapezoid chain links are employed so that an obtuse angle and an acute angle can be formed, and the effect of bark stripping is greatly improved.

Description

technical field [0001] The invention relates to a chain, in particular to a high-strength trapezoidal chain and a manufacturing method thereof. Background technique [0002] Now the country's wood consumption is nearly 500 million cubic meters, including logs, boards, particleboards, fiberboards and other pulp equivalents. Now the external dependence of wood has reached 50%. By 2020, the country's timber demand may reach 800 million cubic meters. Therefore, the tree harvesting market is huge. Taking Heilongjiang as an example, during the "Eleventh Five-Year Plan" period, the timber output in key state-owned forest areas in Northeast China and Inner Mongolia will be 10.805 million cubic meters. [0003] Both North America and Northern Europe are large forestry countries. Russia is the country with the richest forest resources in the world, accounting for 22% of the world's forest resources. It is one of the few countries in the world that allow large-scale exports of timber...
