Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a ridge pounding device in a ridge adjustment machine used for ridge creation, repair work, etc.

[Conventional technology]

Conventional ridge pounding devices for this type of ridge adjustment machine are disclosed in Japanese Patent Application Laid-Open No. 141212/1983 and Japanese Utility Model Publication No. 51-47785.
Publication No. 102411, Utility Model Application No. 53-102411, Utility Model Application No. 53
-20316 publication etc. are known.

In these structures, the machine frame is connected to the rear of the traveling machine body by a coupling mechanism, an earth embankment rotor is installed on the machine frame, and the traveling machine body is run along the old ridge, and the earth mound rotor removes the mud in the field. The embankment is heaped on top of the old ridge, and this embankment is stroked with a fixed ridge coating board, or the leading edge in the advancing direction is hinged and pressed against the rear edge, or the mud at the edge of the old ridge is moved over the old ridge. The structure is such that the embankment is pounded by the crank action of the pounding body.

[Problem that the invention seeks to solve]

However, these conventional structures are not satisfactory in terms of earth embankment efficiency, ridge beating behavior, etc., and have the disadvantage that strong ridges cannot be obtained.

In addition, if we examine each of the above conventional structures, especially the earth embankment structure, embankment coating structure, hammering structure, etc., we find that each conventional ridge coating system has its advantages and disadvantages in the combination of each structure. As a result, it is difficult to obtain optimal ridges, which is disadvantageous in that it is less practical.

In addition, as a known technique, the present applicant's Japanese Patent Application Laid-Open No. 56-9660
Publication No. 3 is known, which uses a crank mechanism to convert rotational motion into reciprocating motion by rotating a crank in the same manner as the prior art mentioned above, and the reciprocating motion causes the striking body to perform reciprocating striking motions. It is configured.

However, in the case of a purely mechanical structure in which the striking body is reciprocated by this crank mechanism, there is a certain limit to improving the ridge striking force due to this structural constraint, and there is also a certain limit to improving the number of ridge strikes. There are limitations, and even though the entire device can be manufactured at a low cost, it is not suitable for making the entire device more compact and lightweight, and it is not always possible to obtain satisfactory results for some ridges. This has the disadvantage that there are cases where it is not available.

[Means for solving the problems] The purpose of the present invention is to solve these inconveniences. A rotating rotor that flips up is provided, a cover member is provided above the rotating rotor and above the ridge, a side cover member is provided on the ridge side 1 of the cover member, and a cover member is provided on the ridge side 1 of the cover member, and a cover member is provided at a rear position in the traveling direction of the rotating rotor. A ridge beating body having a claw-shaped longitudinal cross section adapted to the top surface of the ridge and one side of the ridge is provided, a guide mechanism for reciprocating the ridge beating body is provided, and hydraulic pressure is provided for reciprocating the ridge beating body through the guide mechanism. A ridge beating device for a ridge shaping machine is characterized in that a ridge beating mechanism is provided between the machine frame and the ridge beating body.

[Effect]

When the traveling machine travels along the ridge Z4, the rotating rotor of the machine frame connected to the coupling mechanism piles up mud on the old ridge, and the cover member prevents the mud from scattering outward above the rotating rotor and above the ridge. The section cover member prevents mud from scattering to the sides of the ridge, and the embankment is compacted by being pounded by a hydraulic ridge-beating mechanism by the reciprocating ridge-beating action of a ridge-beating body having a claw-shaped longitudinal section.

In this case, the ridge beating body is guided back and forth by the guide mechanism.

Since this first embodiment has the above-mentioned configuration, when the traveling body 1 runs along the old ridge and rotates the main shaft 9, the scraping blade 6 of the rotating rotor 4 scrapes the field mud. Efficient embankment is created due to the continuous bouncing and rotational bouncing action on the ridge, and the cover member 11 and side cover member 15 reduce the upward force of the rotating rotor 4 and the ridge-up force, and the outward scattering of the mud to the sides of the ridge. can be prevented, and the embankment efficiency can be further improved.

〔Effect of the invention〕

As described above, when the machine frame connected to the coupling mechanism is run along the old ridges by the traveling machine body, the rotating rotor scoops up field mud and continuously splashes it onto the old ridges.
Efficient embankment is possible due to the rotational flip-up action, the cover member prevents mud from scattering outward above the rotating rotor and above the ridge, and the side cover members prevent mud from scattering to the side of the ridge. Embankment efficiency can be further improved, and at the same time, the hydraulic ridge beating mechanism is driven, and pressure oil is supplied to the hydraulic reciprocating vibrator, and the ridge pounding body, which is not guided reciprocatingly by the guide mechanism toward the ridge, is driven by the hydraulic reciprocating vibrator. The ridge pounder makes a reciprocating motion and compacts the embankment, and at this time, the ridge pounder is guided in reciprocating motion by the guide mechanism, so it reliably receives the force associated with the ridge pounding reaction force, and the entire ridge pounder moves smoothly. As the ridge pounding body moves, the vertical cross-section has a shape corresponding to the top surface of the ridge and one side of the ridge, so the top surface of the ridge and one side of the ridge are simultaneously pounded and the embankment is sandwiched between the old ridge and underground and the ridge pounding body. Can be compacted,
Therefore, it is possible to strongly compact the embankment, and furthermore, the ridge beating body can be reciprocated by the hydraulic reciprocating vibrator of the hydraulic ridge beating mechanism, and because of the hydraulic structure, the ridge beating force can be easily varied and the ridge beating force can be improved. It is easy to do, and by changing the number of reciprocations, the number of times the ridge pounder hits the ridge can be easily varied, and the number of times the ridge pounder can be easily increased. It is possible to shorten the time of knocking and sliding contact between the ridge beating body and the ridge top surface and one side of the ridge, thereby reducing friction damage to the ridge tapping surface of the ridge beating body due to sliding contact between the ridge pounding body and the ridge mud as the traveling machine travels. By reducing the frictional resistance, stable and smooth running of the traveling machine is possible, and vibration inside the machine frame that occurs in the case of a crank mechanism can be suppressed, and the ridges can be strengthened efficiently with a large ridge striking force. Compaction can be performed, strong ridges can be obtained, and the entire device can be easily made smaller and lighter, which makes it possible to create and repair good ridges.

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