Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a leaf cutting machine in which foliage is cut off with a cutting blade in a pre-harvest process of root vegetables such as mulberry.

[0002]

Conventionally, as a means for cutting vegetable leaves such as burdock foliage, a rotary blade attached to a horizontal rotation shaft in the left-right direction perpendicular to the machine body traveling direction is used, but the entire surface is cut. Not only does the cut leaves scatter over the entire field and it takes time to collect grass, but also when the cutting edge is brought close to the soil surface to cut the leaves sufficiently, it has a cutting blade that comes in contact with the soil and is cut. There are inconveniences that soil is mixed into the leaves that make post-processing difficult and that the cutting blade is damaged.

[0003]

SUMMARY OF THE INVENTION Therefore, the present invention provides a blade holder which is radially fixed to a rotating shaft which is horizontal in the direction in which the machine body travels, and a flare blade which cuts vegetable leaves is attached to the tip of the blade holder so that the rotating shaft is mounted. The flare blade, which is radiated and arranged in a large diameter shape as the center, cuts the foliage of root vegetables such as kobo well by making it close to the soil surface as much as possible without cutting into the soil, and advances the cut foliage to the body It is collected on one side of the direction and easily picked up to improve efficiency in leaf collection work and the like.

[0004] Further, a release cover for releasing and guiding the vegetable leaf cut by the flare blade to one of the left and right sides in the traveling direction is attached to one of the left and right ends of the outer peripheral cover of the flare blade, and the foliage cut by the flare blade is released. Is collected on one side in the body traveling direction, and the efficiency of the post-process is improved.

Further, a release cover is attached to the left and right ends of the outer peripheral cover of the flare blade so that the height can be adjusted, and the release cover is adjusted to an appropriate height in accordance with various conditions such as the growth of the foliage and the amount of cutting, so that cutting is performed. To enable good release of foliage,
It improves the grass-collecting effect.

A cutting device (7) for cutting the foliage (B), which is a vegetable leaf, is mounted so as to be able to move up and down via a three-point link mechanism (8).

As shown in FIGS. 3 to 5, the leaf cutting device (7) is connected to a PTO shaft (10) at the rear of a transmission case (9) of a tractor (6) via a universal joint (11). A horizontal rotating shaft (12) and the rotating shaft (1);
2) Blade holders (14) whose base ends are fixed radially and equidistantly to a face plate (13) fixed to the rear end, and pivot shafts (15) on front and rear surfaces of the tip of each blade holder (14). A pair of front and rear flare blades (16) that are swingably mounted, and an outer peripheral cover (17) that covers the outside of the flare blade (16) in a substantially semicircular shape
And the foliage (B) cut by the flare blade (16) and attached to the left and right end of the outer peripheral cover (17) via adjusting bolts (18) so as to be adjustable in height.
7) A discharge cover (19) for guiding the discharge to the outside, a horizontal frame (21) connecting the lower ends on both left and right sides of the discharge cover (19) via a pivot plate (20), and a horizontal frame (21).
Left and right lower link brackets (24) for fixing the rear end to the fixing plate (22) of the three-point link mechanism (8) and connecting the front end to the lower link (23), and the outer peripheral cover (1).
7) The front end of the top link (26) of the three-point link mechanism (8) and the left and right masts (27) are fixed to the top link (26) of the three-point link mechanism (8) by being fixed to the front end of the support frame (25) at the upper center. Top link bracket (28) for connecting the middle part through the middle, and left and right lower link brackets (24)
Adjusting bolt (3) is attached to the tail wheel holder (29)
0) and a tail wheel (32) that supports the mounting height freely through a support (31). A lift rod (35) is attached to a lift arm (34) of a hydraulic lift (33) on the upper part of the transmission case (9). The left and right lower links (23) are connected to each other via the torch, and the leaf cutting device (7) is moved up and down.
The cutting height position with respect to the burdock (A) is changed by adjusting the mounting height in 2).

The flare blade (16) is formed in a substantially L-shape by bending the tip end side left and right outward, and the blade holder (14)
As shown in FIG. 5, when the blade holder (34) is rotated about the rotary shaft (12), the blade holder (34) is centrifugally applied to the flare blade (16). ) In the radial direction, and the flare blade (1)
The foliage (B) is chopped off at the curved portion (16a) of 6).

The present embodiment is constructed as described above, and the lowermost flare blade (16) is brought close to the field scene without penetrating the soil to the burdock (A) planted in the field. It cuts the foliage (B)
Post-processing without leaving uncut foliage (B) Good cutting can be performed, and the foliage (B) cut as shown in FIG. 6 is scattered to the left in the direction of the body movement, which is the rotation direction of the flare blade (16), to release the foliage (B). By the guidance of (19), the grass is collected in a single row on the left side along the body traveling direction, and during this collection operation, the foliage (B) can be easily picked up to improve the work efficiency in the post-process.

[0010] In addition, during the rotation operation of the flare blade (16), the diameter of the circular path of the tip of the flare blade (16) about the rotating shaft (12) is much larger than that of a conventional rotary blade or mower, and the flare blade ( The speed of 16) is also high, so that the foliage (B) can be reliably cut, and stable cutting can be maintained without any trouble even if the running speed of the machine body is high.

Further, the discharge cover (19) has an outer peripheral cover (1) capable of adjusting not only the mounting height but also the mounting inclination angle.
7), and by appropriately adjusting the inclination angle of the discharge cover (19), the discharge direction of the foliage (B) can be changed to change the falling grass position.

[0012]

As is apparent from the above embodiments, the present invention is directed to a flare for cutting a vegetable leaf (B) while fixing a blade holder (14) radially on a rotating shaft (12) horizontal to the body traveling direction. Since the blade (16) is attached to the tip of the blade holder (14), the flare blade (16) radiating around the rotating shaft (12) and arranged in a large-diameter shape does not bite into the soil. In addition, the roots and leaves of root crops such as Kobo (A) are cut well by bringing them as close as possible to the soil surface, and the cut foliage (B) is collected on one side of the fuselage traveling direction and easily picked up and collected. It is possible to improve efficiency in work and the like.

The release cover (19) for discharging and guiding the vegetable leaf (B) cut by the flare blade (16) to one side in the traveling direction is provided on the outer peripheral cover (1) of the flare blade (16).
7), the foliage (B) cut by the flare blade (16) is satisfactorily collected on one side in the body advancing direction by the guide of the discharge cover (19). The efficiency of the process can be improved.

Further, since the discharge cover (19) is attached to the left and right ends of the outer peripheral cover (17) of the flare blade (16) so as to be adjustable in height, the growth status of the foliage (B), the amount of cutting, etc. The release cover (19) is adjusted to an appropriate height in accordance with various conditions, thereby enabling excellent release of the cut stems and leaves (B), thereby improving the grass collecting effect.
