Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of use] The present invention relates to a vibrating ridge trimming machine for correcting old thin ridges into a predetermined ridge shape.

[Problems to be Solved by Prior Art and Invention]

In the conventional ridge coating machine, when soil adheres to the ridge coating plate, the coating soil may be peeled off.

The method of hand-painted ridges, which has been used for a long time and is still used, is to plow the ridges while the water remains in the rice field to make a kneaded soil.

 Place the paste on the ridge.

The soil is not attached to the hoe if the soil is placed on the hoe by hitting it with hoe to make ridges.

The present invention focuses on the fact that the sliding motion can be reproduced by attaching an exciter, which gives vibration by rotating the point moving disc in the traveling direction, to a new vibration type rectifier. Was developed.

In addition, in the striking type arranging machine, no matter how large power is used, there is no striking force more than the weight of the machine. In this respect, in the vibrating body method of the present invention, regardless of the weight of the machine, it is proportional to the weight of the shunting plate, and a strong force can be exerted as much as the square of the rotation speed. Also noticed that he had a great advantage.

In addition, soil compaction has an optimum water content ratio depending on the type of soil, and if ridge coating is applied when the conditions are good, there is no problem, but in reality the farmer will be convenient for himself. Since I want to work at a good time, I demand a machine with a wider range of applications, from wet soil to dry soil.

It is good for soil with a lot of dampness to be plastically deformed with a small amount of force, but for dry soil the paddy field that supports the ridges serves as a cushion, so the force applied to the soil except for the part that directly contacts the ridge board is good. Due to the dispersion, it is difficult to crush the aggregates of the embankment.

In such a case, the beating method reduces the working speed and increases the number of times of beating per unit area to cause the aggregate to slide and deform to form a ridge shape, but the voids are large and compaction is not enough. The vibration type rectifier according to the present invention is liable to be slip-deformed because the direction of the force is changed, so that the voids between the aggregates can be compacted very small without slowing down the working speed.

Based on the above idea, we completed the vibration type leveling machine of Japanese Patent Application No. 61-46734.

As a result of making a trial machine based on this invention and actually repeating the trimming test, when one shunting plate in the vibration oscillating device rotates in parallel to the forward direction, it is applied in the direction of compacting the embankment. In addition to the pressure, it also oscillates to the left and right of the ridge, which makes the center of the vibrating body unstable, resulting in a weak strength of the ridge.

The present invention has been completed by studying how to solve this drawback and focusing on adopting the biaxial method.

[Action]

In the box-shaped exciter 2 provided on the upper side, two shunting shafts 6 and 6 ′ which are horizontally arranged in parallel on the front side and the rear side and which rotate in the same direction are provided with the shunting discs 3 and 3 ′ having the same structure. Since the oscillating body 3, 3'is rotated in the traveling direction because it is provided, the vibrating body 2 is hung vertically on the supporting device C through the elastic body 4, so that the vibrating plate B is equally uniform on the front side and the rear side. The vibration of the machine body 1 is simultaneously applied to the vibration plate B through the supporting device C and the elastic body 4 existing in the vibration body 2 and the vibration body 2 at the same time, and the vibration action is performed by applying pressure. Thus, the voids between the soil particles of the embankment are filled, and the embankment is compacted into a predetermined ridge a shape by the vibration plate 2 to be adjusted.

At this time, the shunting discs 3 and 3'having the same structure are arranged in the same direction as the traveling direction on the two rotary shafts 6 and 6'which are arranged side by side on the front side and the rear side in the vibrating body 2. Therefore, as compared with the case where there is only one rotating shaft, an oscillating force is applied to the diaphragm B on average, and the coil spring 5 is adopted as the elastic body 4, so that it is generated between the supporting device C and the oscillating body 2. Since the four coil springs 5 are provided at the four corners of the vibrating body 2, the downward pressure vibration of the vibration plate B becomes extremely strong, and the strong pressure vibration occurs on the pressing surface of the vibration plate B on average. That is, the embankment is strongly compacted.

In addition, the power for rotating the dividing plates 3 and 3'is separated from the power for operating the embankment device A and transmitted to one rotary shaft 6, and the power transmission mechanism D drives the other rotary shaft 6 '. Since it is rotated in the same direction, power is transmitted accurately.
