Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a ridge leveling machine used in rice fields and the like.

[Conventional technology]

Conventionally, this type of ridge adjustment machine was developed in 1983.
Publication No. 10483 is known.

In this conventional structure, a machine frame is provided on the traveling machine body, a rotating rotor is provided on the machine frame to kick up soil onto the old ridge, and a ridge beating plate is provided at the rear position of the rotating rotor in the direction of travel.
It is constructed by providing a ridge-beating mechanism that causes the ridge-beating board to perform a ridge-beating operation.

[Problem that the invention seeks to solve]

However, although this conventional structure of ridge pounding mechanism employs a so-called lever crank mechanism or hydraulic cylinder mechanism, it is only a pounding operation, so depending on work conditions such as embankment conditions and soil conditions, it is difficult to obtain a satisfactory ridge tightening state. This has the disadvantage that it may not be possible to do so.

[Means for solving problems]

The purpose of the present invention is to eliminate these inconveniences.The gist of the present invention is to provide a machine frame on a traveling machine body, provide a rotating rotor on the machine body that throws up soil on the old ridge, and set the machine frame in the traveling direction of the rotating rotor. A ridge shaping machine is characterized in that a ridge shaping body is provided at a rear position, a ridge beating mechanism is provided for reciprocating the ridge beating motion of the ridge shaping body, and a vibrating body is provided to vibrate the ridge shaping body. .

[Effect]

When the traveling aircraft runs along the ridge, the rotating rotor kicks up mud and heaps it on the ridge, and the embankment is
The ridge beating mechanism performs a reciprocating ridge beating operation, and the ridge adjustment body is vibrated by a vibrating body to tighten the ridges.

〔Example〕

1 to 3 show embodiments of the present invention, FIGS. 1 and 2 are the first embodiment, and FIG. 3 is the second embodiment.

In the first embodiment shown in Figs. 1 and 2, reference numeral 1 denotes a traveling machine body as a tractor, and a machine frame 3 is connected to the rear of the machine body 1 by a coupling mechanism 2. A rotating rotor 5 raised on a ridge is mounted on a shaft, a power take-off shaft 6 of a tractor rotates a main shaft 7 of a machine frame 3, a chain mechanism 8 rotates a rotor shaft 9,
The blade portion 10 is used to scrape up muddy soil at the edge of a ridge or the like.

Reference numeral 22 denotes a ridge adjustment body, and in this case, the ridge adjustment body 22 is formed into a rear surface shape adapted to the upper surface of the ridge 4 and one side of the ridge.

Reference numeral 27 denotes a ridge beating mechanism, in which a slide body 11 is provided on the machine frame 3 so as to be slidable toward the ridge 4 by means of a roller body 12, and a hydraulic cylinder 13 is provided on the machine frame 3.
A slide body 11 is connected to the rod of a hydraulic cylinder 13, and a hydraulic pump 14 is disposed on the machine frame 3. The hydraulic pump 14 is operated by a main shaft 7, and an oil supply pipe 15 and an oil return pipe are connected to each other via a switching valve (not shown). 16 connects the hydraulic pump 14 and the hydraulic cylinder 13, and the reciprocating movement of the hydraulic cylinder 13 causes the slide body 11 to perform a reciprocating furrowing movement.

17 is a vibrating body, in this case slide body 1
A hydraulic vibrator as a vibrating body 17 is attached to the lower part of the pipe 1, and the vibrating body 17 and the hydraulic pump 14 are connected to the connecting pipe 1.
8, and attach the mounting plate 19 to the vibrating body 17.
A ridge adjustment body 22 is attached to the mounting plate 19 by bolts 20 and elongated holes 21 so as to be vertically adjustable.

Since this first embodiment has the above-mentioned configuration, when the traveling body 1 travels along the ridge 4, the rotation of the rotating rotor 5 causes the mud at the edge of the ridge 4 to be thrown up onto the ridge, and the embankment is removed by the ridge pounding mechanism 27. The hydraulic cylinder 13 performs a reciprocating ridge beating operation, and the ridge adjustment body 22 vibrates with a hydraulic vibrator 17 to tighten the ridge, thereby making it possible to obtain a sturdy ridge that does not easily collapse.

The second embodiment shown in FIG. 3 shows another example of the ridge beating mechanism 27. In this case, a crank 23 is provided at the rear upper part of the machine frame 3, and two vibration links are provided at the rear lower part of the machine frame 3 toward the ridge 4. 24 is provided protrudingly, an intermediate member 25 is attached to the tip of the vibration link 24, and a rod 26 is installed between the plate surface of the crank 23 and the intermediate member 25,
A hydraulic vibrator as the vibrating body 17 is attached to the intermediate member 25, pressure oil is supplied from the tractor to the hydraulic vibrator as the vibrating body 17, and the mounting plate 1 is attached to the vibrating body 17.
9, and bolts 20 and long holes 2 to the mounting plate 19.
1, the ridge adjustment body 22 is attached so as to be vertically adjustable.

In this second embodiment, when the crank 23 is rotated by the power take-off shaft 6 of the tractor, the ridge straightening body 2
2 is reciprocated by a so-called lever-crank mechanism including two swing links 24, a crank 23, a rod 26, etc., and the ridge straightening body 22 is vibrated by a hydraulic vibrator serving as a vibrating body 17, similar to the first embodiment. Obtain the effect of.

In addition, as another embodiment, it is possible to apply a rotary rotor having a structure in which the rotational axis of the rotor 5 is arranged in a direction substantially perpendicular to the ridge forming direction, and instead of the hydraulic cylinder 13, a similar one thereof, For example, it is possible to use a vibrator with a slightly longer stroke.

〔Effect of the invention〕

As described above, when the traveling machine travels along a ridge, the rotation of the rotating rotor causes the mud at the edge of the ridge to be thrown up onto the ridge, and the embankment is reciprocated by a ridge-beating mechanism and vibrated by a vibrating body. This makes it possible to obtain a sturdy ridge that does not collapse easily.

As described above, the intended purpose can be fully achieved.
