Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a ridge arranging machine, and in particular, in a ridge arranging machine which digs up mud to raise it to an old ridge The present invention relates to an improved compaction mechanism.

2. Description of the Related Art Conventionally, it has been practiced to make ridges in a rice field, to store water by damming it, to make a boundary with another person's rice field, or to make a sidewalk for agricultural work. It is said that such ridges are good in that they do not leak water, that they do not collapse even when a person walks, and that their height and width do not change and are stable.

In order to make such ridges, a method of making kneaded soil on the ridges with a tiller and placing the kneaded soil on the ridges and hitting it with a hoe has been used in the past, but it is easier to save labor. A ridge trimmer that mechanizes the ridge work was developed. There is also a mechanized method of filling the above-mentioned kneaded soil with a hoe, but this has the drawback that it can only be used when the rice field has a lot of water in order to knead the soil and mud. A pump was also developed to supply water, but it was labor-intensive and the operation of the machine was troublesome.

Next, a ridge trimming machine was developed to improve these drawbacks and to be used throughout spring and autumn. This is to dig up the soil with a rotor and raise it up to a ridge, and hit this raised soil with an almost square-shaped hitting plate to harden the top and side faces of the ridge. The striking plate of this ridger is rotatably connected to two parallel links that are connected to a rod provided through a crank mechanism on the power take-off shaft of the tractor and pivotally supported by the machine frame. ,
The rod is moved according to the forward / backward movement in a certain direction in which the forward / backward movement of the rod is restrained by a parallelogram deformation movement by two links. Its workability is improved compared to the previous machine, but the striking pressure The defect that is added only to the upper surface of the ridge,
It has a drawback that it has many mechanically coupled parts and is easily damaged.
Therefore, as an improvement of this, a rectifying machine has also been developed that advances and retreats an almost V-shaped ridge striking plate by using a hydraulic system composed of a hydraulic pump and a piston device that advances and retracts oil like a water gun. Since this also hits the ridge, there was a problem such as noise due to the impact.

Problems to be Solved by the Invention As described above, the conventional leveling machine has a problem in impact when hitting a ridge. Therefore, we disclosed in a previous application a rectifying machine that adjusts the ridge embankment by vibrating it with a vibrating plate, but this one allows the rectifying plate that is vibrated by a vibrating device to be fixed to the machine frame. Since the spring was connected to the provided board, when the embankment hits the ridge plate, the ridge plate was displaced rearward, whereby the spring was extended and its function was diminished.

Means for Solving Problems In order to improve the problems as described above, the present invention was constructed by excavating mud in a machine frame and raising it to old ridges, and by the earth raising means. In a trimming machine having a trimming plate for trimming mud, the trimming plate has a trimming plate main body for trimming the upper and side surfaces of the furrow and a standing wall connected to the front side of the trimming plate main body, and An oscillating device is provided on the main body of the ridge board,
There is provided a ridge adjuster in which the ridge plate main body is connected to a base plate provided on the machine frame by an expansion / contraction device including a cylinder and a piston and a spring provided outside or inside the cylinder.

Action When the ridge plate is vibrated to vibrate the particles of soil, the structure in which the particles are aggregated can be made particularly dense by performing the high speed operation. At this time, if a spring is provided together with a telescopic device that consists of a cylinder and an insert and that expands and contracts at a set position,
Since the expansion device can be prevented from moving even when the pressure of the embankment is applied to the ridge plate, the spring can also function at the set position.

Also, the standing wall on the front side of the ridge board can prevent soil from coming in from the front when arranging and prevent it from slipping backward.

Embodiment Next, an embodiment of the present invention will be described with reference to FIGS.

Next, the operation of this embodiment will be described.

First, as shown in FIG. 1, the ridge trimmer A is attached to the tractor T to enter the rice field, and the power take-off shaft g is driven to operate the rotor R and the ridge trim plate 2. 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 direction of the to the obtuse angle forward with respect to the ridge.

When the tractor T is advanced in parallel with the ridges in this state, the rotor R scrapes the cross section of the ridges and excavates the soil of the rice paddy field to heap these soils. The soil piled up in this way is compacted by the ridge plate 2 which repeatedly vibrates. The vibration speed is, for example, 2000 to 3000 rpm, but is not limited to this. At this time, the soil raised by the rotor R pushes the ridge plate 2 backward, but the expansion / contraction devices 4a to 4d move the piston back and forth in the fixed cylinder, so the ridge plate does not move rearward and the set position does not change. Can work with. The tail wheel
Due to the reaction of 14 from the wall surface of the depression, the pressing force of the ridge plate main body 2a against the soil is increased, and the soil is more compacted.

The piston may be like a plunger.

Although the spring is provided on the outside in the above, as shown in FIG. 4, a spring 4'a-3 may be provided between the cylinder 4a-1 and the piston 4a-2. The spring may be provided in the space above the drawing.

The positions of the cylinder and piston may be upside down.

Further, in the above, the piston operates in the air of the cylinder, but oil may be used to improve the damper effect.

Further, although the power is taken from the decelerator in the above, an engine different from the tractor may be mounted so that the vibrating device can be operated directly or via a flexible shaft.
At this time, the trimming device may be self-propelled.

Further, although the rotor R is substantially perpendicular to the ridge in the above, it may be parallel to this or may be a plow-like one.

Further, the ridge board can be used in combination with the ridge hitting board shown in the conventional example.

Effects of the Invention As described above, according to the present invention, the ridge board is vibrated, so that the soil is compacted, and the sound is small at the time of the work. The problem of can be solved. Although the soil is hardened in this way, a spring is provided between the rectifying plate and the fixed base plate together with the expander / contractor consisting of the cylinder and the insert body. Since the plate can be operated in the set position without being displaced, the spring can sufficiently perform its function. As a result, the ridge plate can maintain its ridge surface parallel to the ridge surface, so that not only a reliable vibration pressure can be applied to the embankment, but also the shock of vibration can be mitigated by the spring.

In addition, since the ridge striking plate has a standing wall on the front side, the soil coming in from the front can be stopped and prevented from falling backward, and the soil can be efficiently compacted.
