Description

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

[Conventional technology]

Hitherto, this type of ridge adjustment machine has been known as disclosed in Japanese Utility Model Publication No. 57-10483 and Japanese Patent Application Laid-Open No. 60-57905.

In this structure, a machine frame is provided on the traveling machine body, a rotating rotor is provided on the machine frame, and a ridge beating body having a shape adapted to the upper surface of the ridge and one side of the ridge is provided at the rear position of the rotating rotor in the traveling direction. It is constructed by providing a ridge-beating mechanism that causes the striking body to perform a reciprocating ridge-beating operation.

[Problem that the invention seeks to solve]

However, in the case of the conventional structure, the mud thrown up by the rotating rotor is pounded by the ridge pounding body as the traveling machine moves, so the running resistance is excessive as the mud that remains high is pounded by the ridge pounding body. In some cases, unevenness in the embankment inevitably occurs, and the resulting unevenness may cause parts to become extremely dense, or conversely, parts may not be sufficiently tightened by pounding, and the inside of the ridge. There may be some inconveniences such as uneven tightening may occur when looking at the entire structure.

[Means for solving problems]

The present invention aims to eliminate these disadvantages, and its gist is to provide a machine frame on the traveling machine body, provide a rotating rotor on the machine frame, and provide a cover member above the rotating rotor. , in which a ridge beating body having a shape adapted to 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 a ridge beating mechanism is provided for causing the ridge beating body to perform a reciprocating ridge beating operation,
A ridge adjustment structure characterized in that a pre-treatment member is provided at a position rearward of the rotating rotor above the ridge and is movable in a reciprocating manner and can come into contact with the embankment, and a reciprocating mechanism for reciprocating the pre-treatment member is provided. It's on the machine.

[Effect]

When the traveling machine travels along a ridge, the rotating rotor heaps up mud, a pre-treatment member that moves back and forth on the embankment smoothes and smooths the high parts of the embankment, and a ridge pounding mechanism reciprocates the ridge top surface by pounding the embankment. and one side of the ridge by tapping with a ridge beater of a shape that matches the side surface.

A pin 39 is pivotally connected to the middle of the member 30, and the tip of the lever 37 is pivotally connected to the rear end of the pretreatment member 30 by a pin 40.

Since this first embodiment has the above-mentioned configuration, when the traveling machine l travels along the ridge 4, the rotating rotor 5 plows up the inside of the old ridge 4 and kicks up mud, and the ridge pounding mechanism 24, in this case, plows up the mud. The ridge pounding body 9, which reciprocates the ridge pounding motion by means of the crank 26, the connecting rod 27, etc., is used to tighten the ridge, but at this time, the reciprocating mechanism 31 causes the pretreatment member 30, which in this case circulates and reciprocates, to come into contact with the upper part of the embankment.
