Title: Shigetake Akanuma: Innovator in Hydraulic Technology
Introduction
Shigetake Akanuma is a notable inventor based in Chigasaki, Japan. He has made significant contributions to the field of hydraulic technology, holding a total of 4 patents. His innovative designs focus on improving the efficiency and effectiveness of rock splitting and breaking apparatus.
Latest Patents
One of his latest patents is a hydraulic rock splitter, which features an apparatus with a pair of presser cheeks designed for insertion into a drill hole. This invention utilizes a slider wedge that is slidably engaged between the presser cheeks. The forced descent of the slider wedge, driven by a hydraulic cylinder assembly, results in the lateral motion of the presser cheeks away from each other. The presser cheeks are supported by the cylinder body through two pairs of parallel spaced leaf springs, which are positioned on opposite sides of the slider wedge. This design allows for upward displacement of the leaf springs without buckling, ensuring durability and reliability during operation.
Another significant patent is for an apparatus that mechanically breaks up rock. This invention incorporates dust-proof membranes across both ends of the divided surfaces defined by halves of wedge guide members. Each membrane features projections that are thrust into longitudinally extending C-shaped cross-section grooves formed along the divided surfaces of the wedge guide members. This innovative design enhances the functionality and efficiency of rock breaking operations.
