Abstract

The invention discloses a rotating flexible shaft supporting tube formed by asymmetrically combining single-sheet type supporting blades, comprising an inner tube body, elastic supporting blades and rigid supporting blades, wherein the elastic supporting blades and the rigid supporting blades are integrally and fixedly connected on the outer surface of the inner tube body, have smaller thicknesses than the thickness of the inner tube body and are respectively arranged along the length direction of the outer surface of the inner tube body; the distance between the top end parts of the elastic supporting blades and the tube center of the inner tube body is the same as the distance between the top end parts of the rigid supporting blades and the tube center of the inner tube body; the rigid supporting blades are distributed on the outer surface of the inner tube body, which corresponds to a central angle less than or equal to 180 degrees of the inner tube body; the number summation of the elastic supporting blades and the rigid supporting blades is 3-8; and the root parts of the elastic supporting blades are in single-sheet type. The invention is suitable to being used on a straight metal outer casing and a plant protecting machine with an arc bending pipe. When in use, the invention not only can prevent the followed running phenomenon, but also can prevent the inner tube body from being stuck with the rotating flexible shaft.

Description

technical field [0001] The invention relates to a rotating flexible shaft support tube with an asymmetric combination of single-piece support blades. Background technique [0002] In the lawn mowers and scarifiers of plant protection machinery, the support tube must be used to support the rotating flexible shaft. When in use, the support tube is inserted into the metal outer tube, and the rotating flexible shaft transmits power to the working cutter head to perform operations. In the past, a general support tube was mainly composed of an inner tube body and support blades fixedly arranged on the outer wall of the inner tube body. The radial directions of the support blades and the inner tube body were consistent, and the thickness of the top and bottom ends of the support blades was uniform. During installation, in order to ensure the stable insertion of the support blades in the metal outer tube, the distance between the outer end of the support blades and the center of the...
