A plurality of tilling claws 4, 4... 4 are provided on the outer circumference of a tilling pipe 36 attached to a lower portion between the side transmission case 32 and the side plate 35. . . Is helically attached at a predetermined pitch over the entire width, and the soil is excavated and crushed by the driving rotation of the tilling pipe 36.

Tillage claws 4,4. . . The upper portion of the rotation trajectory is covered with a main cover 5, and a rear cover 6 is attached to the rear end of the main cover 5 so as to be vertically swingable around a fulcrum shaft 10. The rear cover 6 is a leveling plate that hangs down by its own weight to level the surface of the excavated mud.

As shown in the side view of FIG.
The rear end of the rear hitch bar 41, 4 projects rearward from the connect pipes 33, 34 in side view.
The front end portion of each of the motors 1 is attached with left and right pins 42, 42, respectively. The rear hitch bar 41 is connected to the mast 25 by a screw cylinder 44, and rotates the handle 43 at the upper end to adjust the vertical position with the pin 42 as an axis. A left-right toolbar 45 is attached to the rear end of the rear hitch bar 41 that is extendable in the front-rear direction. The work can be performed by attaching another working machine (not shown) such as a ridge or a gauge wheel to the toolbar 45, though not shown. .

As shown in the plan view of FIG. 1, the rotary tilling device 3 is wider than the left and right rear wheels 15,15. Then, front light storing portions S1 and S1 are provided at the front left and right sides of the upper outer surface of the main cover 5, which is the main body of the wide portion, and rear light storing portions S2 and S2 are provided at the rear left and right sides by painting, stickers, bolts or screws. It is provided detachably through such as. In this case, direct painting with a brush or spray painting with a spray gun is easy, but cannot be removed and the durability is poor. Also, baking coating increases durability, but depending on the size of the members, a larger coating line is required. With a sticker type, it can be easily attached to the required place as needed, and repair in case of damage is also easy. If the light storage section S is of a detachable member 7 type via bolts or screws, a mounting member is required, but the components can be reduced in size and baking can be easily performed, or the detachable member 7 can be removed when not needed. Since it is hard to be damaged, it can be used for a long period of time, and cost can be reduced in consideration of a long span.

Further, the same rear surface light storage sections S3 and S3 are detachably attached to the left and right side portions of the rear outer surface of the rear cover 6 via painting, stickers, bolts, screws, or the like. The mounting width of these light storage sections S is
May be attached to a portion wider than the width of the aircraft 1 at a location visible from the front of the vehicle, and may be further expanded inward at a location visible from the rear of the agricultural tractor 13.

Next, the wide working machine 8 shown in FIG. 3 will be described. The wide working machine 8 is a boom sprayer and is attached to a farm tractor 13 of a riding management machine that runs as four-wheel steering with front and rear wheels 14 and 15 having substantially equal diameters. The upper and lower links 4 are provided by projecting left and right columns 47, 47 at a front part of a pair of left and right frame frames 46, 46 arranged in the front-rear direction along the body 1 and having one end attached to the column 47.
At the other end of the wide working machine 8, which is a boom sprayer, a central boom 8a at the middle in the left-right direction is attached to the other end of the wide working machine 8,48.

The wide working machine 8, which is a boom sprayer,
During the spraying operation, the boom sprayer is extended linearly in the left-right direction as shown by the imaginary line in FIG. 3 and sprayed to a width of about 15 meters at a time. The center boom 8a is slightly wider than the width of the fuselage 1 and is about 1.7 m. When traveling on a road, the side boom, which is the side protruding portion 9, is substantially along the side of the fuselage 1 as shown in the figure. It is easy to run by folding.

Reference numeral 49 denotes a lifting / lowering actuator, which can be telescopically operated by a hydraulic cylinder, a geared motor, or the like, and moves the wide working machine 8 up and down by expanding and contracting. Reference numeral 50 denotes an opening / closing actuator, which comprises a hydraulic cylinder, a geared motor, and the like, which is disposed between the left and right ends of the center boom 8a and the inner end of the side boom, and which can be telescopically extended. The side boom which is the side protruding portion 9 is expanded and contracted to
Or the center boom 8
The side boom is extended linearly in the left-right direction with respect to a.

A tip light storing section S4 is provided at the tip of the side boom. The tip light storing section S4 is also connected to another light storing section S.
Similarly to the above, it is detachably attached via a paint, a sticker, a bolt, a screw, or the like. In addition, in addition to the above, the light storing section S may be a self-lighting seal, a fluorescent seal, an electric light, or the like. In such a case, it is possible to easily purchase and attach or attach members individually.

[0021]

The light storing section S absorbs the brightness of daytime sunlight and other artificial light and emits the light in the dark, and the light storing section appears to glow as it gets darker. For this reason, those provided with the luminous part S on the side of the upper surface of the main cover 5 of the rotary tilling device 3 or on the outer surface after the rear cover,
When the work is prolonged and the surrounding area becomes dark and the ridge is cultivated around the ridge, the end of the rotary on the side of the main cover 5 is shining from the driver, so that the distance from the ridge can be easily understood and workability is improved.

Furthermore, the rotary tilling device 3 suspended from an oncoming vehicle, an overtaking vehicle or the like at the time of self-propelled traveling on the road at night can be easily checked, and even if the lights of the agricultural tractor 13 are difficult to see with the working machine. It is safe because the number of collisions is reduced. And when the light accumulating part S is provided in the left and right ends of the wide working machine 8, when the spraying work is performed until twilight,
The position of the end of the wide working machine 8 with respect to the end of the field can be easily confirmed even from a distant place, so that the workability is improved and no fatigue occurs. In addition, when the agricultural tractor 13 with a working machine is mounted on a carrier such as a truck and the vehicle travels in a different direction, the light storage unit S can be used by both the own vehicle and the other vehicle. The height, width, etc., of the inside of the carrier when the vehicle is traveling forward and backward can be easily determined and safe.

As described above, in the present invention, the light-storing section is used as a mark to facilitate driving, or to show the light-storing section to others to improve safety awareness.
