Abstract

PROBLEM TO BE SOLVED: To provide a spiral mower capable of mowing with obstacles such as roadside trees, poles and a stone fence, reducing the scatter of pebbles because of a low rotating speed, and recovering reaped grass etc. at the same time.SOLUTION: A driving shaft 7 is rotated through an electric motor or an oil engine, and rotation is transmitted to a gear 4 fixed to the driving shaft 7 and transmitted by a gear 5 fixed to a rotary cylinder 3 to rotate a spirally wound rotary blade 1. A non-rotary blade 2 is spirally wound in an opposite direction to the rotary blade 1 and fixed to a casing 6 through the rotary blade 1 so that the blades of the rotary blade 1 and non-rotary blade 2 are formed in a scissors state to reap grass etc. The reaped grass etc. pass through the rotary cylinder 3 from the rotary blade 1 and are sucked to a suction blower connected to a recovery port 8 and recovered from a recovery opening W.

Description

  The present invention relates to a machine suitable for tea picking and mowing machines.

  Conventionally, a tea picking / mowing machine is generally performed by a clipper type or by rotating a circular saw with an electric motor or a gasoline engine.

  Tea picking, garden care, etc. are done with clippers.

  The method of cutting the grass by rotating the nylon cord at high speed can effectively use only soft grass where there is a hard obstacle.

  With conventional mowers, poles, roadside trees, stone walls, and other surrounding areas are dangerous and cannot be mowed, and grass growing in gaps such as stone walls and stone pavements has been difficult with mowing machines.

  The grass that has been cut must be collected separately, and a clipper-type recovery device has been proposed for tea pickers and large machines.

In order to achieve the above object, the present invention has been made to solve such a problem, and is wound in a spiral shape with the blade portion of the blade wire in a triangular shape or trapezoidal shape of a single blade or a double blade, on the inside, A non-rotating blade was installed. Along the inner diameter of the non-rotating blade, the cutter wire was wound in a spiral shape opposite to the non-rotating blade with the blade portion of the rotating blade on the outside, and the rotating blade was installed inside.
The blade wire is wound spirally at the optimal intervals for stone walls, poles, street trees, etc., and the rotating blade wound opposite to the non-rotating blade by rotating the outer non-rotating blade and the inner rotating blade is scissors. Forms a shape and cuts grass and the like.
By rotating the rotating blade in the direction of collecting grass, etc., it is conveyed to the collection port, and the grass, etc. is sucked and collected by the blower.

  The invention of this device makes it possible to mow work by preventing the damage of poles and roadside trees by making the winding interval of the non-rotating blades optimal, reducing the number of rotations by cutting with scissors, You can eliminate scattering accidents.

  Sectional drawing of embodiment of the mowing machine which concerns on this invention.   It is a spiral left-handed non-rotating blade 2 blade part figure of the cutter wire of the mower according to the present invention.   It is a 1 blade part figure of a spiral right-handed rotary blade of the cutter wire of the mower according to the present invention.

Embodiments of the present invention will be described with reference to the drawings. Reference numeral 1 in FIG. 3 denotes a blade part of a spiral right-handed rotary blade 1, which is fixed to the rotary cylinder 3 of the drive unit in FIG.
In FIG. 2, the non-rotating blade 2 of a left-handed spiral is fixed to the casing 6 of FIG. 1 through 1 of FIG. 3.
The rotary shaft 7 is rotated counterclockwise via an electric motor or an oil engine (not shown), transmitted to the fixed gear 4, transmitted to the fixed gear 5 to the rotary cylinder 3, and rotated to the right. . The non-rotating blade 2 and the rotating blade 1 are formed in a scissors shape to cut grass or the like.

  The collection port 8 is fixed to the casing 6 and the grass and the like cut through the collection port W are collected through the collection port W (not shown).

Claims (2)

A non-rotating blade was installed by winding it in a spiral shape with the blade portion of the blade wire in the shape of a single-edged or double-edged trapezoid or triangle.
Along the inner diameter of the non-rotating blade, wrap the blade wire in the same shape as above with the rotating blade facing outward and spirally rotating in the opposite direction to the non-rotating blade, and rotate the inner blade with the rotating blade. Spiral mowing machine that cuts grass or picks tea leaves, etc. installed so that each non-rotating blade and rotating blade are always formed in a scissors shape.   Spiral mowing machine installed so that the harvested tea leaves or grass can be collected by a blower with a spiral rotating blade rotating in the direction of the collection port.
