Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a ridge adjustment device for repairing old ridges and creating new ridges.

[Conventional technology]

Hitherto, as this type of ridge adjustment device, structures such as those shown in Japanese Patent Application Laid-open No. 56-96603 and Japanese Utility Model Application No. 57-10483 filed by the present applicant are known.

With this conventional structure, mud that has collapsed and accumulated on the edge of the old ridge due to weathering, etc. is splashed up and raked up, and the embankment is pounded and compacted with a ridge pounding board to create a new ridge. It is an attempt to create a

[Problem to be solved by the invention]

However, in the case of this conventional structure, the above-mentioned ridge adjustment work is performed while the top surface of the old ridge remains collapsed due to weathering, etc., and the top surface of this old ridge is overgrown with weeds and the surface layer is hardened. Sometimes, soil is piled up on the ridge in this condition,
These weeds, hard soil, etc. get in the way, and the adhesion between the top surface of the old ridge and the embankment decreases, and the integrity between the mud and soil decreases.
This has the disadvantage that the ridges may easily collapse and become weak.

[Means to solve the problem]

The present invention aims to solve these inconveniences, and its gist is that a machine frame is connected to the traveling machine body by a coupling mechanism, and a plurality of raking blades are installed on the machine frame to splash soil onto the old ridges. A rotating rotor is provided,
A cover member is provided above the rotating rotor and above the ridge, and a ridge trimming body having a longitudinal cross-sectional shape that matches the upper surface of the ridge and one side of the ridge is provided at a rear position in the traveling direction of the rotating rotor, and the ridge trimming body is provided above the rotating rotor and above the ridge. A ridge shaping device is provided, comprising: a ridge shaping mechanism that operates to level the ridge; and a cutting blade for cutting the upper surface of the old ridge is disposed at a forward position in the direction of movement of the rotating rotor so as to be movable up and down. .

[Effect]

When the traveling machine is run, the cutting blade first scrapes off the top surface of the old ridge, and this scraping action scrapes out the top surface of the old ridge, including the weeds that grow on this top surface and the hard soil layer on this top surface. During this excavation, the excavation blade moves up and down according to the upper surface of the ridge, and then the rotating rotor rotates to splash and mound soil onto the old ridge.
A cover member provided above the rotating rotor and above the ridge prevents mud from scattering.Next, a ridge trimming body with a vertical cross-sectional shape that matches the top surface of the ridge and one side of the ridge is provided at a rear position in the direction of movement of the rotating rotor. The ridge adjustment mechanism works to level the ridges and tighten the embankment and old ridges.

A rotating intermediate shaft 20 is supported on the upper part of the machine frame 5 via a main shaft 13 and sprockets 18 and 19, and a crank plate 21 is fixed to the rear of the intermediate shaft 20. The crank plate 21 and the ridge adjustment body 3 are connected by a connecting rod 22, and the rotational motion of the intermediate shaft 20 is converted into a reciprocating motion of the connection rod 22, so that the ridge adjustment body 3 is repeatedly oscillated and tightened by hitting the ridge. It consists of

Reference numeral 4 denotes a cutting blade, which is provided at a forward position in the direction of movement of the rotating rotor 2, and whose rotational axis is arranged approximately in the direction in which the ridges extend, so as to cut out the upper surface of the old ridges into a concave arc shape. A main gear 23 is fixed to the front part of the rotor shaft 2c of the rotating rotor 2, and a gear case 24 is supported so as to swing around the rotor shaft 2c, and an intermediate gear 25 is provided inside the gear case 24 to adjust the rotation direction appropriately. , 26,

As described above, when the traveling machine runs, the present invention first scrapes the upper surface of the old ridge, and by this scraping action, the upper surface of the old ridge is removed from the weeds growing on this upper surface and the hard soil on this upper surface. During this cutting, the cutting blade moves up and down according to the upper surface of the old ridge, and then the rotating rotor rotates to splash and mound the soil on the old ridge. The cover member provided above the ridge prevents mud from scattering, and the vertical cross section aligned with the top surface of the ridge and one side of the ridge provided at the rear position in the direction of movement of the rotating rotor.
The shaped ridge body works by the ridge alignment mechanism to hammer and tighten the embankment and old ridges, so that the embankment can be built on top of the old ridges that have been removed, including weeds and hard soil layers. The adhesion between the mud on the old ridge and the embankment can be improved and the integrity can be enhanced, and the ridge can be tightened to that extent to obtain a robust ridge that will not easily collapse.

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