TH6950C3 - Support for lawn mower blades - Google Patents

Abstract

DC60 (19/04/54) Support for lawn mowers consists of a support pipe fitting into Oblique, where the inside area is equipped with a pivoting mechanism to support the insertion of the external drive shaft. And at the open end The bottom of the support tube is diagonally connected to the side of the pipe. Support for wearing vertically where the inside area has a rotating support mechanism. Pass installed For supporting transmission of power in driving rotation from the support mechanism The drive is rotated so that the drive power is delivered to the outer screw rod and the bottom area of the vertically inlet support tube has the top of the cover. The upper blade is connected with the bottom end of the outer swivel rod. Emerged for a while For passing through a through hole in the center of the cutter disc Grass to be attached to the nut inserted outside the convex and alignment. With a hole through the bottom And the inside at the inlet of the blade cover below will have the edge The inner support shoulder with the rolling support bearing inserted. For supporting insertion Through the outer screw to secure the nut inserted on the outside. The support for the mower blade consists of a support tube. Oblique, where the inside area is equipped with a pivoting mechanism to support the insertion of the external drive shaft. And at the open end The bottom of the support tube is diagonally connected to the side of the pipe. Support for wearing vertically where the inside area has a rotating support mechanism. Pass installed For supporting the transmission of power in driving rotation from the support mechanism The drive is rotated so that the drive power is delivered to the outer screw rod and the bottom area of the vertically inlet support tube has the top of the cover. The upper blade is connected, with the bottom end of the outer swivel rod. Emerged for a while For passing through a through hole in the center of the cutter disc. Grass to be attached to a nut inserted outside the convex and alignment. With a hole through the bottom And the inside at the inlet of the blade cover below will have the edge The inner shoulder, all around with the rolling support bearing inserted. For supporting insertion Through the outer screw to secure the nut inserted on the outside.

Claims (1)

1. The support base for the mower blade consists of an oblique insert (1) which is a hollow, open-end tube where the inside area is mechanically attached. Supporting the drive rotation is installed. For supporting the insertion of the power transmission axis It is driven from the outside through the top opening of the oblique inlet support tube (1) and the lower open end of the oblique inlet support tube (1) is connected to the side of the The vertically inlet support tube (2), the vertically inlet support tube (2), is a hollow inner tube where On the inside, there is a drive-through mechanism installed. For supporting It transmits power to drive rotation from the rotating support mechanism in order to transmit power Drive the spinning rod onto the outer screw rod (3) in the back and forth, and the bottom of the vertically inlet support tube (2) is the top of the top blade cover (4) welded. Attached to which The top blade cover (4) looks like a cover that is a socket for the part. Concave inward and outward convex area where the outer convex area is Connected to the lower open end of the vertically inlet support tube (2), with the lower end of the outer swivel rod (3) protruding for some time. For inserting through a through hole in the center (5) of the mower blade plate (6) to secure it to the lower blade cover (7) and to the inward side part. On the top of the blade cover (4), there is an inner shoulder edge (8) installed, where the inner shoulder edge (8) is characterized by a thin shoulder edge and a through hole for support. The perforation of the outer helix rod (3) and the lateral side of the through hole supporting the perforation of the outer helix rod (3) has a raised inner shoulder edge (9) for connection. Into the inner edge, through the center hole (5) of the blade (6), while the end of the outer screw rod 3 is attached to the lower blade cover (7). The lower blade cover (7) will look like a cover that is a socket for the part. It is concave inward and convex on the outside and has a through-bottom (10) for the tip of the blade, the inward side overlapping the bottom of the mower blade (6) and the through hole area. The bottom (10), located inside the recess of the lower blade cover (7), has the surrounding inner shoulder support (11) to support insertion. The entrance of the pivoting support bearing (12) and the outer area of the surrounding inner shoulder support (11) has at least one shoulder edge connecting the side (13) for the connection between the outside of the The shoulder edge supports the inside around (11) with the inner edge at It is the open end at the concave outer side of the surrounding inner shoulder support (11) to strengthen the surrounding inner shoulder support (11) and through the bottom through hole (10). The outer convex arc of the lower blade cover (7) is the surrounding concave edge (14) for supporting the insertion of the turning support nut (15) in order to support the rotation of the end. Bottom of outer screw rod (3)
