Dual-piston compressor for lawnmowers, saw blade parts.

Abstract

We offer low-noise lawnmowers. [Solution] We had previously filed a patent application for a compressed air lawnmower (P50-279), but we thought it would be good to have a saw blade that rotates with air pressure, so we devised this and filed a patent application. It is sufficient to sweep and cut down grass and weeds, but we thought that there would be a need for a saw blade that can cut tough shoots, bamboo, goldenrod and other weeds, so we devised two types of lawn mowing parts that can cut with an air-pressure saw blade and filed a patent application. By keeping the tank constantly filled with air using a W-piston compressor, the work can be done by supplying air without interruption. As a result, it is possible to mow the lawn quietly without the loud noise of conventional lawnmowers, and it is a world-first lawnmower with technology that Japan can be proud of.

Description

Technical Field

[0001] Conventional lawn mowers and grass cutters are currently noisy, making it difficult to watch TV, study, talk, or make phone calls. Therefore, a lawn mower and grass cutter with a quiet compressor and a small compression sound of a W-piston compressor was invented and developed.

Background Art

[0002] There has been no improvement in noise yet. Therefore, a pneumatic lawn mower and grass cutter was invented, where the sound during air compression in the presser is quiet, and it is also quiet when cutting grass, causing no nuisance to the neighborhood.

Disclosure of the Invention

[0003] The W-piston compressor always fills the air tank with air and operates quietly, only making the pump sound and the cutting sound, so it does not cause any nuisance to people. Compressed air is ejected thinly TIFF2026082576000001.tif9166 It is for cutting grass and is a technology of Japan, which is the first in the world and Japan is proud of. Means for Solving the Problems

[0004] TIFF2026082576000002.tif31166 Means for Solving the Problems

[0005] With a W-piston compressor, air is compressed and sent into the air duct, and the air pressure is used to form a plate TIFF2026082576000003.tif13165 Effects of the Invention

[0006] TIFF2026082576000004.tif10169 Among them, it does not cause any nuisance to the neighborhood.

Best Mode for Carrying Out the Invention

[0007] Conventional lawnmowers and grass trimmers are very noisy, making it difficult to listen to television, study, have conversations, or make phone calls. Therefore, we have devised and developed a quieter lawnmower / grass trimmer with a W-piston compressor that produces less compression noise. (Note: The last sentence about hydraulic engines seems unrelated to the preceding text and is likely a separate, unrelated snippet.) [Examples]

[0008] We are currently conducting prototype testing from various angles, and the results have been verified. We are currently considering this with the manufacturer. [Industrial applicability]

[0009] Industrial applicability marks the beginning of the industry's first ever upset competition, the first year of its kind.

Claims

1. It is a device that uses air pressure to rotate the saw blade (circular saw blade).

2. This was designed to reduce noise and operating sounds.

3. Air pressure is used to rotate a plate (aluminum plate), which in turn rotates the saw blade on the rotating shaft, cutting the grass.
