[Conventional technology]

Conventionally, as this type of arranging machine, JP-B-57-10483, JP-B-60-57905, JP-B-52-41712,
As in Japanese Utility Model Laid-Open No. 52-104519, a traveling machine body is provided with a machine frame, a rotary rotor for raising soil is provided on the old ridge, and the machine can be tightened in a backward position in the traveling direction of the rotary rotor. It can be tightened by vibration with an oscillating device, such as one provided with a rectifying body, or as disclosed in JP-A-61-47103, JP-A-61-158105 and JP-A-62-190002. It is known that a ridged body is provided.

[Problems to be solved by the invention]

However, in the case of the above-mentioned conventional structure, the ridged body travels linearly toward the ridge and is vibrated and struck to move while tightening the ridge.Therefore, the traveling resistance may increase depending on the amount of embankment in the front. The smoothing of the tightening movement is hindered, and the ridge tightening becomes insufficient, so that it may not be possible to obtain good ridges.

The present invention is intended to solve these inconveniences, and its gist is to provide a machine frame on a traveling machine body, to provide a rotary rotor for raising soil on the old ridges, and to advance the rotary rotor. A ridged body having a shape matching the upper surface of the ridge and one side surface of the ridge is provided at a rear position of the ridge, and the ridged body is moved toward the ridge by a ridge tightening operation, a backward movement in the advancing direction, and a separating operation in a direction away from the ridge In the ridge trimmer, a ridge tightening mechanism for providing a circular locus motion consisting of four repeating forward movements in the forward direction is provided.

[Action]

The traveling vehicle travels along the ridges, the soil is piled up on the old ridges by the rotating rotor, and the ridged body moves the ridges toward the ridges, moves backward in the advancing direction, and moves away from the ridges and moves forward in the advancing direction. The embankment forms a circular locus motion consisting of four forward motions, and the embankment is ridged by the circular locus motion of the ridge body having a shape matching the upper surface and one side surface of the ridge.

The mounting bracket 31 is mounted by the bolts 32 via.

33 is a ridged body, which is formed in a vertical cross-section that matches the upper surface of the ridge and one side surface of the ridge, and the ridged body 33 is attached to the mounting bracket 31 by a bolt 34 and a selection hole 35 so that it can be adjusted up and down. .

36 is a mud body, and rubber, sponge, fur, resin, or the like is used, and the mud body 36 may be eliminated, or a member with good sliding may be attached to the hit surface of the ridge body 33. .

Reference numeral 37 denotes a wheel that can move up and down, and is for supporting the machine casing 3.

Since the first embodiment is configured as described above, the traveling machine body 1 travels along the old ridge 4 and the power take-off shaft 6 is rotated, while the rotary rotor 5 continuously crushes the field soil on the old ridge 4 while rotating. The cover member 12 prevents the mud from scattering above the rotary rotor 5 and laterally of the ridge, and on the other hand, the ridge clamping mechanism.
The upper surface of the ridge 4 and one side surface of the ridge 4 are clamped by a ridged body 20 having a shape of a vertical cross-section by ridges to perform ridger work. At this time, the ridged body 33 moves in a circular path to form a ridge. Tighten
That is, in this case, the ridge body 33 is shown in FIG. 5 consisting of four repeating movements of a ridge tightening operation toward the ridge, a backward movement in the traveling direction, a separating operation in a direction away from the ridge, and a forward movement forward in the traveling direction. Since the ridge is tightened by performing a motion having a circular motion locus R having a radius of the eccentricity ε, the ridge can be surely and smoothly moved to tighten the ridge even if the embankment height in front of the ridge body 33 is high, and By the slidable contact action on the ridges, the adhesion of mud to the ridge body 33 is suppressed and the finished state of the ridge surface is good, and further, the operation speed can be improved by smoothing the movement of the ridge body 33 by the circular trajectory motion, It is possible to obtain robust ridges and improve work speed.

Secure the mounting arm 47 to the bottom of the
Mount the mounting bracket 31 with the bolt 34 and the selection hole 35 so that it can be adjusted up and down.
Is fixed, and a transmission 48 is arranged between the power shaft 8 and the telescopic shaft 27 connected to the rotary shaft 41.

Since the third embodiment has the above-mentioned structure, when the rotary shaft 41 rotates via the transmission 48, the slide shaft 46 reciprocates due to the action of the eccentricity ε, and also the rocking motion about the rocking shaft 42. The ridge body 33 makes a circular locus motion with a circular motion locus R shown in FIG.
