Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a vibration type ridge trimming machine for correcting old thin ridges into a predetermined ridge shape.

[Conventional technology]

As a conventional leveling machine, there is known a system in which, as in Japanese Utility Model Publication No. 57-10483, embankment is embanked on a ridge and the embankment is continuously hammered and solidified by a ridge striking plate which is raised and lowered by a crank mechanism.

This type of ridge trimming machine is used most often as a practical machine because it surely presses the embankment, but on the other hand, it has a drawback that vibration and noise are large because the ridge striking plate strongly hits the ridgeline.

In addition, it is the same type of continuous striking type ridger, but
There is also known a ridge trimming machine, which uses hydraulic pressure to raise and lower the ridge striking plate, such as -57905. Although this hydraulic type has a high tapping speed, it is expensive because it uses a hydraulic mechanism, and has drawbacks such as oil leakage.

In addition, a vibration type leveling machine which presses and solidifies the embankment by a vibration action to solve these drawbacks has been proposed, but a viable leveling machine having practical performance has not been developed yet.

[Problems to be solved by the invention]

In order to solve these drawbacks, the applicant did not adopt the continuous hitting method described above, but gives vibration to the diaphragm using a vibrating device and fills the voids between the soil particles of the embankment with this vibration. This is to propose a vibration type ridge trimmer that can be put to practical use for compacting.

The shaft 4 is disposed, and the diaphragm C with the vibration oscillating device D is attached to the mounting plate 31 provided on the machine frame 3 in a repulsive pressure state in which a repulsive force is applied obliquely from the upper side in the bisector direction toward the ridge angle portion. Then, the bending wall 12 facing upward is continuously provided at the front edge of the diaphragm C, and the cover plate 35 for dropping the mud repelled by the rotor 24 of the embankment device B onto the ridge is placed on the machine frame 3 in a state in which the upper side of the ridge is hidden.

[Effect of device]

As described above, the present invention provides the embankment device on the front side of the machine frame,
A longitudinal section matching the desired ridge section on the rear outside of this embankment A diaphragm with the outer side and the front and rear sides opened is installed on the rear side of the machine frame, and an oscillating device is installed on this diaphragm. This flexible shaft is installed, the diaphragm with the vibration oscillating device is attached to the mounting plate provided on the machine frame in an elastic state, and the bending wall facing upward is connected to the front edge of the diaphragm. Since the cover plate that causes the splashed mud to fall on the ridge is projected on the machine frame in a state of concealing the upper side of the ridge, the mud repelled by the rotor of the embankment device is the upward bending wall provided on the front edge of the diaphragm by the cover plate. The ground is embanked in front of and the vibration is applied by the diaphragm.

At this time, the elastic force is applied to the mounting plate provided on the machine frame, and the elastic force is applied to the diaphragm with the vibration oscillating device from the diagonally upper direction toward the ridge by applying the force of the machine frame toward the ridge. Since the vibration effect is added, excess embankment is pushed out from the open end of the diaphragm, and the remaining embankment is strongly pressed and solidified, so that it can be shaped into a sturdy ridge that does not collapse.

In addition, since power is distributed to the vibration generator via a flexible shaft, it can be used in a durable manner without damaging the machine body due to the transmission of violent hammering vibration to the machine body, as in the conventional striking plate of the hitting system. It becomes a vibration type ridge trimmer.
