Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a ridge adjustment machine.

[Conventional technology]

Conventionally, this type of ridge adjustment machine has been known as disclosed in Japanese Patent Application Laid-open No. 61-47103 and Japanese Patent Application Laid-open No. 61-47104.

In this structure, a machine frame is provided on the traveling machine body, a rotating rotor is provided on the machine frame, and a vibrating body having a shape adapted to the top surface of the ridge and one side of the ridge can be slid onto the ridge at the rear position of the rotating rotor in the direction of movement. The vibrator is provided with a vibration mechanism for vibrating the vibrator.

[Problem that the invention seeks to solve]

However, in the case of the conventional structure, the mud thrown up by the rotating rotor is tightened by the vibrating body as the traveling machine moves, so the high mud is tightened by the vibrating body arranged almost in a fixed manner. The resistance may become excessive, and unevenness in the embankment inevitably occurs, resulting in unevenness that may result in parts becoming extremely dense, or conversely, parts being insufficiently tightened. However, there may be disadvantages such as uneven tightening when looking at the inside of the ridge as a whole.

The present invention aims to eliminate these inconveniences, and its gist is that a machine frame is provided on the traveling machine body, a rotating rotor is provided on the machine frame, a cover member is provided above the rotating rotor, and the machine frame is provided with a rotating rotor. A vibrating body having a shape adapted to the top surface of the ridge and one side of the ridge is provided at a rear position in the traveling direction of the rotating rotor so as to be able to slide on the ridge, and a vibration mechanism for vibrating the vibrating body is provided. The ridge straightening machine is characterized in that a pretreatment member is reciprocably provided in a rear position and capable of contacting the embankment above the ridge, and a reciprocating mechanism for reciprocating the pretreatment member is provided.

[Effect]

When the traveling machine travels along a ridge, the rotating rotor heaps up mud, and a pretreatment member that moves back and forth on the embankment smooths out the high parts of the embankment, and a vibrating body slides into contact with the top surface of the ridge and one side of the ridge. Tighten.

In this case, the pretreatment member 34, which circulates and reciprocates, comes into contact with the upper part of the embankment, and is flipped up by the rotating rotor 5 to form the ridge 4.
The unevenness that occurs in the construction direction of the ridge and the horizontal direction of the ridge is smoothed out, and the unevenness of the embankment is corrected and smoothed. As a result, the embankment with less unevenness can be tightened by the vibrating body 9, and it is possible to prevent partial tightening or partial tightening. Over-tightening can be suppressed, uneven tightening inside the ridge 4 can be suppressed, and the ridge 4 can be tightly tightened as a whole, and smooth running can be achieved by reducing running resistance.

In this case, in this embodiment, the pretreatment member 34 is located in the rear part of the cover member 7, and the pretreatment member 34 moves in a vertical circulation from a position close to the upper wall of the cover member 7 to a position where it contacts the embankment.

Therefore, the structure of the reciprocating interlocking mechanism 35 is not limited to this embodiment, and a cam mechanism or the like may also be used.

In this case, the vibration mechanism 22 is a mechanism that generates vibrations by the action of the eccentric body 23, but it may also employ a hydraulic vibrator, an electromagnetic pipe rake, a reciprocating piston vibrator, or the like.

Further, the shape of the pretreatment member 34, particularly the shape of its tip, is not limited to a simple flat plate shape as in this embodiment, but can be designed with appropriate changes.

Further, the present invention can also be applied to a case where the rotary rotor 5 is a purchased rotor 5 whose axis of rotation is arranged in a direction substantially perpendicular to the direction in which the ridges 4 are formed, and can also be applied to a case where the vibrating body 9 is in the form of a roller.

〔Effect of the invention〕
