Abstract

------05/08/2019------(OCR) Page 1 of 2 pages. Summary of Invention: A cutting blade set for a shoulder-mounted grass trimmer. It consists of a blade holder and a bent blade. The bent blade is shaped like a pentagonal plate with a square base and four screw holes for attachment to the blade holder. Above the base is a triangular, uneven, serrated edge with teeth on both sides. The edge of this pentagonal plate is bent away from the base to create a curved blade. Two or more pairs of these curved blades are attached to both sides of the blade holder, positioned to create balance, forming a cutting blade set for a shoulder-mounted grass trimmer. When the blade holder rotates, the bent blade creates a cutting path outside the plane of the holder, resulting in a cup-like shape extending from the plate. ------------ ------12/06/2018------(OCR) Page 1 of 1 page.

The vertically rotating blade assembly consists of a pentagonal plate with a square base and four screw holes for attaching to the blade mounting plate. Above the base is a triangular blade section with a rough, serrated surface on both sides. This pentagonal plate is bent at the triangular section to create the blade assembly. These blades are then attached to both sides of the blade mounting plate (two pairs or more), positioned to achieve balance, forming a cutting blade set for a shoulder-mounted grass trimmer. As the blade plate rotates, the bent blade sections on both sides create an off-plane cutting path, resulting in a cup-like (wide-mouthed, narrow-bottom) cutting width extending from the plate on both sides. ------19/10/2560------(OCR) Page 1 of 1. Summary of Invention: A cutting blade set for a shoulder-mounted grass trimmer consists of a blade mounting plate that is adjusted to rotate vertically and an assembled blade in the form of a pentagonal plate. A 3 x 7.5 cm square base has four bolt holes for attaching to the blade mounting plate. Above the base is a triangular shape with sides 6 cm long at the apex, featuring an uneven, serrated surface on both sides. This triangular section is cut and bent at an angle greater than 40 degrees from the base to form the blade assembly. These blades are then attached to both sides of the blade mounting plate (two pairs or more), positioned to achieve balance, forming a cutting blade assembly for a shoulder-mounted grass trimmer. As the blade plate rotates, the bent blades on both sides create a cutting path outside the plane of the mounting plate, resulting in a circular cutting area extending from the plane of the mounting plate on both sides. ------------ Edited 03/04/2017 (15/03/2017) The cutting blade assembly for a shoulder-mounted grass trimmer consists of a blade mounting plate that is adjusted to rotate vertically and assembled blades, modified from triangular combine harvester blades by bending the ends more than 40° away from the base, attached to opposite sides of the plate in pairs. Approximately 10 cm from the center, at least two pairs are needed, but they must be installed in a position where centrifugal force is balanced. When the blade disc rotates, the deflected blade sections on both sides will create an impact point outside the plane of the blade holder, resulting in a circular impact area extending outwards from the plane of the blade holder on both sides. -------------- The blade assembly for a shoulder-mounted grass trimmer consists of a blade holder that is adjusted to rotate vertically and assembled blades with the tips bent approximately 45° away from the base. These are attached to each side of the disc in pairs or individually, approximately 10 cm from the center, at least two pairs are needed, but they must be installed in a position where centrifugal force is balanced. When the blade disc rotates, the deflected blade sections on both sides will create an impact point outside the plane of the blade holder.

The cutting blade set for shoulder-mounted grass cutters consists of a flat, circular mounting plate and a blade that is securely attached to the plate with 4 nuts. It has a special characteristic: A pentagonal blade with a triangular, serrated cutting edge that bends away from the square base is called a composite blade. ------19/10/2017------(OCR) Page 1 of 1. Claim 1. The cutting blade set for shoulder-mounted lawn mowers consists of a composite blade as a key component. It is a pentagonal plate with a bent end. The square base measures 3 x 7.5 centimeters and has four screw holes for attaching to the blade mounting plate. Above the base is a polygonal shape with 6-centimeter-long, serrated edges on both sides. This pentagonal plate is cut at the triangular portion, bending it more than 40 degrees from the base to create the composite blade. When these composite blades are attached to both sides of the blade mounting plate (two pairs or more), and positioned so that they rotate and create balanced centrifugal force, a cutting blade set is formed. Shoulder-mounted grass cutter ------------ Edited 03/04/2017 (15/03/2017) 1. Assembled blade (2) is an important part developed from the triangular combine harvester blade (1). It has 4 bolt holes for fastening to the base or blade mounting plate. The overall shape of this blade is a pentagon. The base is about 1 part high, and 2 parts above the base are triangular. The sides at the apex are not smooth, with teeth on both sides. Take this combine harvester blade (1) and bend the triangular part to bend from the base more than 40 degrees, to get the assembled blade (2). When attached to the blade mounting plate (3) to work in balance, it will create a special characteristic: the cutting line will be angled out from the plane of the blade mounting plate (3) in a circle, or it is called the width of the cutting line will be a circle according to the rotation of the blade mounting plate (3), and will be as wide as the line of the blade mounting plate to the tip of the blade that bends out on both sides. When used to cut small branches and trees, the width of the cutting line will cut the small branches and trees into short pieces. No need to collect for burning. The cutting disc assembly (6) for shoulder-mounted grass trimmers consists of a blade holder (3) with a round or other shape, with two or more pairs of blade assemblies (2) attached to both sides of the disc. When the cutting disc assembly is adjusted to rotate vertically, the debris shield is moved closer to the cutting disc and its position and direction are adjusted to block debris that may be thrown towards the user, and it can then be used as needed. -------------- Edited 11/10/2016 The cutting disc assembly for shoulder-mounted grass trimmers consists of a blade holder with a round or other shape, with two or more pairs of blade assemblies attached to both sides of the disc, causing cutting outside the blade holder's line, with blade assemblies attached in pairs or individually, and two or more pairs. When the disc rotates, a balanced centrifugal force is generated, and it can work. 2. The assembled blade has a base that is securely bolted to the blade holder. The part extending from the base is the blade edge, which can be smooth or uneven, triangular or other shapes. The tip of the blade is bent away from the base, attaching to the blade holder at a 40° or higher angle. ------------------------------- The blade assembly for shoulder-mounted grass trimmers consists of a blade holder, which can be round or other shapes, with assembled blades attached to both sides of the holder. The cutting action occurs outside the blade holder's alignment, either by attaching the blades in pairs or individually. There are at least two pairs. The rotating disc creates balanced centrifugal force, allowing for efficient operation. The assembled blade has a base that is securely bolted to the blade holder. The part extending from the base is the blade edge, which can be smooth or uneven, triangular or other shapes. The tip of the blade is bent away from the base, attaching to the blade holder at a 40° - 50° angle.
