Description

[Detailed Description of the Invention] Conventional Technology The present invention relates to a leveling machine, in which a mud is dug up to build up on an old ridge, and the leveled up soil is compacted by a vibrating device. The present invention relates to a rectifying plate having improved motion behavior.

2. Description of the Related Art Conventionally, paddy fields are used to make ridges, to store water by damming them, to serve as a boundary with other people's rice fields, or as a sidewalk for agricultural work.

Conventionally, as a machine for making ridges, various things such as hitting ridges using a lever-crank mechanism, hitting ridges using hydraulic pressure, etc. are known, but these are strokes of the ridge hitting plate when hitting ridges, for example, 100 mm. It was also large, and the repetition frequency was also relatively small. This type of ridge trimming machine is suitable for making sturdy ridges, but for example, partition ridges and sidewalks are provided to prevent seedlings from falling due to ripples in rice fields that have grown due to recent ground improvement. For ridges that do not need to be combined, the ridge striking machine with a shorter stroke and a higher frequency may have better workability.

For this reason, a type of leveling machine that uses a vibrating device to vibrate the leveling plate has also been developed.

Problems to be Solved by the Invention However, the ridge plate of this vibration type ridge trimmer is supported by springs so that the ridge face portion can vibrate, but the soil raised by the rotor is below the ridge face. When it entered, the leveling surface was lifted, the spring was compressed, and the room for vibration of the leveling surface was reduced, so that efficient vibration could not be applied to the embankment.

Means for Solving the Problems In order to solve the above-mentioned problems, the present invention comprises a soil raising means for raising mud in a machine frame and raising it to a ridge,
In a rectifying machine equipped with a rectifying plate having a rectifying surface part that can be vibrated by a vibrating device for arranging the mud raised by the earth raising means, an arbitrary position of an intermediate part is rotatably supported by the machine frame. The present invention provides a rectifying machine characterized in that the supporting rod is provided, the ridge plate is attached to one end of the supporting rod, and a weight is provided on the other end side of the supporting rod.

Action A rectifying plate is attached to one end of the support rod that is rotatably supported in the middle part, and a weight is provided on the other end side, so the rectifying plate is supported when pressure is applied to the ridge surface part above the soil. It is lifted by the rotation of the rod, the weight then facilitating its rotation.
The soil pressure on the ridge surface portion is released, and the ridge surface portion can vibrate with a predetermined amplitude.

This auxiliary ridge face plate may be provided with a sub-oscillating device 3b which is actuated by the flexible shaft 3'b like the above-mentioned oscillating device.

It is preferable that the above-mentioned trimmed surface main body and the auxiliary trimmed surface are made of a material such as high-tensile steel plate, fiber reinforced plastic, and stainless steel because they are lightweight and durable. At this time, a slightly deformable material such as a thin steel plate may be used to adapt to the specific state of the embankment.

The suspending piece 4f is attached to a supporting rod 5, and an intermediate portion of the supporting rod 5 is rotatably supported by an arm 6 and a weight 5a is suspended at the tip thereof. This weight

There is. Note that the wheels may be rotated as the main machine frame 1 moves forward without forced rotation.

Next, a method of using the trimmer shown in FIGS. 1 to 4 of this embodiment will be described.

First, as shown in FIG. 2, the trimming plate 2 is assembled, and as shown in FIG. 1, the trimming machine A having the weight 5a is attached to the tractor T.
Attached to the rice field to drive the power take-off shaft g to drive the rotor R
And the ridge board 2 is operated.

Then, the height of the entire leveling machine is adjusted so that the rotary blades of the rotor R can penetrate into the side surface of the ridge and the surface soil of the paddy field, and the height of the leveling plate 2 is adjusted to the height of the ridge, and the tail wheel 14 Adjust the orientation of.

When the tractor T is advanced in parallel with the ridges in this state, the rotor R scrapes the side surfaces of the ridges and digs up the rice field to raise these soils into the ridges. The soil piled up in this way has repetitive oscillating surface main bodies 2e and 2f and an auxiliary arranging surface plate 2j.
Is compacted by.

This vibration speed is, for example, 2000 to 3000 rpm, but
It is not limited to this. At this time, the substrate 4 is rotated by the screw rod 4h, and the soil piled up by the rotor is removed and the soil is formed on the ridge surface main bodies 2e, 2f.
Adjust the angle so that it will not invade and overflow
The adjusting position is fixed with a rotation stop bolt 4i and a nut 4'i.

In this way, the leveling work is performed, but since the soil is finely crushed and vibrated by the crushed soil projecting pieces of the landslide plate, the soil can be compacted effectively, but at this time, the soil is the leveled surface main body 2e, Even if 2f and the auxiliary ridge face plate 2j are pushed upward, the support rod of the ridge plate 2 is rotatably supported and the weight 5a is provided at the tip thereof, so that one end of the support rod is The ridge plate and the seesaw having a weight at the other end are rotated so that the soil pressure is released and vibration can be performed with a predetermined amplitude.

When the ridges have a trapezoidal cross section, the angle of the ridge surface main bodies 2e and 2f should be approximately V-shaped.If the ridge has a triangular cross section, the angle should be triangular. In this case, the ridge surface main bodies 2e and 2f may be extended in one plane. In addition, the rear surface of the ridge surface main bodies 2e and 2f may be formed in a step shape so that the rear side is lower than the front side, and the soil may be compacted in two steps, or this may be performed in multiple steps.

In the above, power is taken from the decelerator, but an engine other than the tractor may be mounted so that the engine can be operated via the vibration exciter or the flexible shaft. At this time, the trimming device may be self-propelled.

Further, the rotor R may be parallel to the ridge, or may be a plow-like one.

Although the weight 5a is used in the above description, a spring provided between the support rod 5 and the machine frame 1 may be used.

Effects of the Invention As described above, according to the present invention, since the ridge plate is rotatable via the support rod, even when the ridge surface portion is pushed up by the soil, the pressure is released to a predetermined level. Can be vibrated and the soil can be compacted with a predetermined amplitude.
