Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a mower capable of mowing on ridges.

[Problems to be Solved by Prior Art and Invention]

In a conventional mower, a grass cutting blade disposed in front of the machine rotates at high speed to stroke weeds. In this method, when weeding on the ridges, the central part can be cut, but the left and right end parts cannot be cut well.

In order to solve such a drawback, a ridge mower of Japanese Patent Publication No. 2-21769 and a ridge mower of No. Kaikaihei 2-100418 developed by the present applicant have been proposed, but both hold a grass cutting blade plate. The fulcrum of the holding arm that is tilted forward and backward to reciprocate left and right is located substantially in the center of the front surface of the mower body 2. Therefore, since the left and right reciprocating motion is stroked in a circular locus, the angle of the reciprocating motion has to be increased, and in the case of a wide ridge, the defect that the left and right sides are left uncut has not been solved.

The present invention provides a mower capable of mowing on ridges that solves the above drawbacks.

[Means for Solving the Problems]

 The gist of the present invention will be described with reference to the accompanying drawings.

The mowing mission case 18 is attached so that the upper part of the mowing mission case 18 is pivotally attached to the front center of the mowing machine body 2 equipped with the wheels 1 so that the lower part of the mowing mission case 18 projects to the side of the mowing machine body 2. Mowing machine 2 seen from the driver
This mowing mission case 18 is installed diagonally to the right side of
A swinging device 5 is provided on the lower front side of the upper part of the reciprocating rotary body 22 standing on the swinging device 5, and a mounting base 4 ′ of the holding arm 4 is provided above the reciprocating rotating body 22.
And a holding arm 4 is provided so as to be able to reciprocate left and right in a front-down inclined state, and a grass cutting blade plate 3 is provided at the tip of the holding arm 4 so as to rotate counterclockwise. The present invention relates to a mower capable of mowing on a ridge, characterized in that it is provided so as to mow the grass on the ridge when moving the plate 3 from the outside on the right side to the inside of the mower body 2.

[Action]

 The mowing blade plate 3 is designed to rotate counterclockwise.

Since the upper part of the mowing mission case 18 is pivotally attached to the front center of the mowing machine body 2 substantially in the center, this mowing mission case
The lower part of 18 is mowed with the upper part of the mission case 18 as a fulcrum and is obliquely arranged to the right as seen from the driver, whereby the mowing blade plate 3 provided at the tip of the holding arm 4 is positioned on the right side of the mowing machine body 2. In this state, the rotational power is transmitted to the mowing blade plate 3,
When the holding arm 4 is swung left and right by the swinging device 5, the mowing machine body 2 is mowed on the ridge, and the mowing blade plate 3 moves to the left from the position outside the right side of the ridge. Since the movement reciprocates, the weeds on the ridge, which are relatively narrow, are neatly wiped off with a single cut.

If the ridge width is wide, adjust the stroke of the reciprocating rotation of the holding arm 4 to a small amount, first mow the right half or more, and then make a U-turn, and stroke the remaining weeds from the right side to the center on the left side. Moving forward, the weeds on the ridges, which are relatively wide, will be neatly brushed and mowed by two reciprocating mowing operations.

〔Example〕

The present invention shows an example of a preferred embodiment, in which the upper part of a mowing mission case 18 is pivotally attached to a substantially central portion of the front side front surface of a mowing machine body 2 equipped with wheels 1, and a mowing mission case.
The mowing mission case 18 is installed obliquely toward the right side of the mowing machine body 2 as seen from the driver so that the lower part of the mowing machine body 2 projects laterally. The mounting base 4'of the holding arm 4 is fixed to the upper part of the reciprocating rotary body 22 provided upright on the swinging device 5, and the holding arm 4 is provided so as to be able to reciprocate left and right in a front downward tilt state. 4 is provided at the tip of 4 so as to rotate counterclockwise, and when the holding arm 4 is reciprocally rotated, the grass cutting blade plate 3 is moved from the outside on the right side to the inside of the grass cutting machine body 2, and the grass on the ridge is removed. The present invention relates to a mowing machine that is also capable of mowing on a ridge provided for mowing.

〔The invention's effect〕

Since the present invention is configured as described above, the lower part of the mowing mission case is located on the right side of the mowing machine when viewed from the driver without setting the setting position of the base of the arm on the front of the machine to the center of the front of the machine. Is installed so as to project outward, and a swinging device is provided on the lower front side of the obliquely mowing mission case. Since the grass cutting blade is provided on the arm, the swiveling device drives and rotates the tip of the holding arm to swing the grass cutting blade from the right outside to the inside of the ridge. It can be neatly mowed by wiping, and if the ridge is wide, adjust the stroke of the reciprocating rotation of the holding arm to a small amount, first mow the right half or more, and then make a U-turn, and the remaining weeds from the right side as well. On the left center When weed off the grass and move forward, weeds on a relatively wide ridge will be neatly wiped off by two reciprocating shavings. Become an opportunity.
