Description

[Detailed Description of the Invention] Industrial field of application The present invention relates to a leveling machine, and in particular, digs up mud to build up the old ridges and compacts the loaded soil. It relates to an improved mechanism.

2. Description of the Related Art Conventionally, it has been practiced to make ridges in rice fields to store water by damming water, to make a boundary with other people's rice fields, or to use as 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 Invented by the Invention As described above, the conventional ridge trimmer has a problem in impact when hitting the ridge. Therefore, we have clarified in the previous application about a rectifying machine that adjusts the embankment of the ridges by vibrating it with a diaphragm, but this one can support and fix the rectifying board that is vibrated by a vibrating device to the machine frame. Since it was connected to the board provided at by a spring, when the embankment hits the ridge board, the ridge board is displaced rearward and the spring is stretched so that its function is diminished. Also,
There is a problem that the pressure of the embankment acts on the ridge board at one time and the load becomes excessive, and the embankment is compacted at one time, so that compaction is insufficient.

Means for Solving Problems In order to improve the above problems, the present invention provides a soil raising means for excavating mud in a machine frame and raising it to an old ridge, and a mud raised by the soil raising means. In a trimming machine having a trimming plate to be trimmed, the trimming plate is composed of an upper face plate and a side face plate, and is formed in a shape in which the front of each is gradually raised, and the trimming plate is attached to the machine frame at its front end. (EN) Provided is a rectifying machine characterized in that the rectifying plate is connected in a retractable manner, a rear end side of the ridge adjusting plate is an open end, and a vibrating device is provided on the rear end side.

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, since the main body of the vibration control part of the ridge control board was set free against the machine frame and pulled, even if pressure was applied to the ridge control board, the soil could be released and compacted. it can. In addition, since the ridge-side portion of the ridge board is formed by gradually raising the front, the embankment is gradually pressed and then vibrated, so that it is compacted well and the ridge board is oversized at one time. You can prevent it from being overloaded.

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

In FIG. 1, T is a tractor, A is a trimming machine, and the trimming machine A has a machine frame consisting of a main machine frame 1 and a portion to which a later-described ridge plate is attached. The tractor T is attached to a mounting frame a provided at an upper rear portion through links b and c, and is rotatably connected to rotatable links d and e provided at both lower rear portions of the tractor, Further, the front upper part of the main machine frame 1 and the center of the upper rear part of the tractor are connected by an adjusting link f whose length can be freely adjusted, and the adjusting device f held by the adjusting link f at an angle determined by these is omitted from the drawing. It is possible to rotate downward through the mounting frame a that is rotated by a hydraulic device, and to return to the original position by rotating the mounting frame a upward by the hydraulic device.

In the rectifier A, the speed reducer is connected to the power transmission shaft connected to the power take-off shaft g of the tractor via the universal joint, the transmission shaft is connected to the reduction gear, and the rotor R is connected to the transmission shaft. The rotation force of the power transmission shaft is attached to the transmission shaft so that the rotation force is decelerated and the direction is changed by the decelerator, and the rotation direction is rotated in a direction opposite to the rotation direction corresponding to the traveling direction of the tractor. As a result, the axis of the rotor R is oriented substantially at right angles to the advancing direction of the tractor and rotates in the direction opposite to the rotational direction of the advancing direction of the tractor.

Reference numeral 1'denotes a cover plate for covering the upper portion and both sides of the rotor R, and 1'a a vertical moving plate having wheels traveling on the upper surface of the ridge.

2 is a ridge plate, which has a vibrating part main body 2a and a filling pressing part 2b,
The vibrating part main body 2a is formed in a substantially V-shaped cross section that can contact the upper surface and the side surface of the ridge, and a vibrating plate 2a-1 is attached to the center of the vibrating part main body 2a. It is like this. This oscillating device is such that the eccentric body rotates when the flexible shaft 3a receives power from the decelerator driving the rotor R. In addition, the embankment pressing portion 2b is formed by an elastic plate such as a leaf spring so as to continuously and gradually rise upward from the vibrating portion main body 2a and has a substantially V-shaped cross section, the upper end of which is the cover plate 1 '. It reaches the position corresponding to the upper part of the rear end. Then, the upper part thereof is attached to the support rod 5, and this support rod 5 is fixed to the arm 6, and this arm is attached to the slider 7.
Is stuck to.

The slider 7 has fixed shafts 9 and 9'fixed to a mounting plate 8.
Is movably fitted to the base plate, a screw hole is provided in the center thereof, and a screw rod 10 is screwed into the screw hole. The screw rod is supported by a support plate 11 and a handle 12 is provided at its tip. The slider 7 can be moved up and down by operating this handle. The slider 7 is provided with slits in the fitting holes of the fixed shafts 9 and 9 ', which are opened and closed by bolts and nuts, and the slider is tightened and fixed to these fixed shafts, or when the slider is unfastened. It can be moved.

Reference numeral 13 denotes a horizontal position adjusting plate to which the mounting plate 8 is attached and which is provided so as to be movable in the horizontal direction. Reference numeral 14 denotes a tail wheel which runs along the wall surface of the recess after the rotor R is dug up.

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 side surfaces of the ridges and digs up the soil of the paddy field to raise these soils into the ridges. The soil thus piled up is first elastically and gradually pressed by the embankment pressing portion 2b of the ridge plate 2, and then is fully compacted by the vibrating portion main body 2a which repeatedly vibrates. This vibration speed is, for example, 2000 to 3000
Although rpm is illustrated, it is not limited to this. At this time, since the oscillating plate has the vibrating part main body free, it can be operated while releasing the pressing force of the embankment. 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.

In the above, power is taken from the decelerator, but an engine other than 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.

Moreover, the above-mentioned ridge board can be used together with a conventional ridge hitting board.

Effect of the Invention As described above, according to the present invention, since the ridge embankment is gradually pressed by the front side of the ridge board, a full-scale vibration is applied at the rear side of the ridge embankment, so that the embankment changes from coarse to dense. It is possible to solve problems such as noise accompanying the soil leveling machine that is gradually compacted and can reduce the noise during the work. Although the soil can be hardened in this way, the vibrating body of the ridge control plate is free, so even if the ridge control plate receives external force from the embankment, it can operate while releasing this pressure. The soil is compacted in a natural way without any load.
