Description

[Detailed Description of the Invention] Conventional Technology [Technical Field] The present invention relates to a ridge trimming machine, in which mud soil is dug up to be raised to an old ridge, and the ridge trimming machine for improving the tail wheel is improved. .

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.

These trimming machines are provided with tail wheels for receiving a recoil by a ridge striking plate or a rectifying plate and stably holding the machine frame to guide and guide the machine frame.

Problems to be Solved by the Invention However, the tail wheels of these ridge-beating and vibration-type ridge trimmers are composed of rotatable wheels that are grounded, and are used when the ridge trimmer is moved during ridge trimming work. , Which rotates with its movement, and if there are many straws and grasses in the rice field, they may become entangled and hinder the rotation, which may hinder its function as a tail wheel.

In addition, since the ridge plate of the vibration-type ridge adjuster has its ridge surface portion made parallel to the length direction of the ridge, and the soil raised by the rotor is prepared as it is, all the raised soil is removed. Was unable to enter under the ridged surface, and sometimes escaped over the ridged surface, which was inefficient. Also,
The strength of compacting the soil on the ridge was the same before and after the ridge surface, and the compaction was sometimes insufficient.

Means for Solving the Problems In order to solve the above problems, the present invention oscillates by digging up mud in a machine frame and raising it to a ridge, and a vibrating device that arranges the mud raised by the earth raising means. In a trimming machine equipped with a trimming plate having a freely adjustable trimming surface part, the trimming plate rotatably supports a shaft in the machine frame in the width direction of the ridge and in a substantially horizontal direction, and vibrates on the shaft. A vibrating plate equipped with a device is connected so as to be integrally rotatable in the length direction of the ridge, and the ridged surface portion is attached to the vibrating plate so as to be integrally rotatable in the length direction of the ridge. In addition, a rotation angle fixing mechanism for fixing the rotation angle to the machine frame is provided so that the inclination angle of the ridge with respect to the length direction can be adjusted, and a cutting blade is provided on the outer periphery behind the machine frame. It is characterized by the provision of a rotating body that can be freely grounded It provides a trimming machine. At this time, it is preferable to forcibly rotate the rotating body.

Action Since the cutting blade is provided on the outer circumference of the rotating body, straws and grasses of the rice fields that come into contact with the rotating blade are cut and are not entangled in the rotating body.

In addition, since the slope angle of the ridge surface part with respect to the length direction of the ridge can be adjusted, it is possible to increase the penetration angle of the soil piled up on the ridge by the rotor or the like into the ridge surface part and Since the soil can be squeezed and sent to the rear while vibrating, the compaction can be made stronger toward the rear.

This compaction is performed well by the fact that the leveling surface portion is pressed well against the embankment of the ridge due to its reaction by the support by the grounding of the rotating body.

It is like this. The rotating body may be rotated with the forward movement of the main machine frame 1 without being forcedly rotated.

Next, a method of using the trimmer shown in FIGS. 1 to 3 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 trimmer A is attached to the tractor T to enter the rice field, and the power take-out shaft g is driven to drive the rotor R and the trimmer. The board 2 is operated.

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 excavates the soil of the paddy 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, 2000-30
00 rpm is exemplified, but not limited to this. At this time, tail wheel 1
Since the cutting blade 14c of 4 is forcibly rotated, the straw and grass in the rice field are cut along with its running, so that they smoothly operate without being entangled. In addition, by adjusting the angle in the length direction of the ridges of the ridge surface main bodies 2e, 2f and the auxiliary ridge surface plate 2j, it is possible to increase the invasion angle to the soil piled up on the ridges at the front end, and as it goes backward, The soil can be narrowed down, and vibrations are transmitted as well as the soil in the rear and it is compacted well, and efficient compaction can be performed, but due to its reaction due to the support by the contact of the tail wheel when compacting it. The compacted surface is well compacted by being pressed well against the embankment of the ridge.

In this way, the trimming work is performed, but the trimming plate body 2e,
If the ridge has a trapezoidal cross section, the angle of 2f should be almost V-shaped.If the ridge has a triangular cross section, it should be triangular.If the higher ridge hits only the side, the ridge surface main body 2e, 2f Should be extended in a plane.

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.

Further, although the above description has been made on the vibration type ridge trimmer, the same can be applied to the ridge striking ridge trimmer.

Effects of the Invention As described above, according to the present invention, the cutting blade is provided on the outer periphery of the rotatable and groundable rotating body provided at the rear of the machine frame, so that the straws and grasses in the rice field can travel there. It is possible to prevent them from being entangled with the rotating body, to smoothly perform the operation, and to perform the smoothing work. Further, since the ridge surface portion is provided so as to be rotatable with respect to the length direction of the ridges and the inclination angle with respect to the length direction of the ridges can be adjusted, it is possible to prevent the soil on the ridge from entering the ridge surface portion. The compaction can be performed efficiently without any unevenness, and at the same time, the compaction is performed better due to the reaction caused by the support by the grounding of the tail wheel, and the vibration type The performance of the trimming function of the ridger can be further enhanced.
