Description

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

[Problems to be solved by the conventional technology and device] As a conventional ridge-arranging machine, as in the case of Japanese Utility Model Publication No. 57-10483, the earth is embanked on a ridge, and this embankment is continuously struck by a ridge striking plate that moves up and down by a crank mechanism. A method of tapping and hardening has been proposed.

The applicant devised a rectifying device that uses a hydraulic mechanism instead of a crank mechanism to speed up the tapping action, and then gives a vibration to a rectifying plate that can be gently adjusted, and this vibration vibrates to consolidate the embankment. Developed a type trimming machine.

It was confirmed that good arranging work could not be performed in any arranging machine unless the arranging plate was always pulled at the correct position with respect to the ridge.

In this respect, as in Japanese Utility Model Publication No. 54-110508 and Japanese Utility Model Publication No. 58-8008, the corners of the upper surface of the ridge protruding from the marker device are pointed to the side of the tractor, and the rotating marker wheel is installed side by side with the front wheel. Then
It is already known that the tractor is moved straight by advancing the marker wheel along the ridge so as to improve the ridge coating work.

However, attaching a marker device to the tractor only serves as a guide for the straight or forward position of the tractor, and the ridge trimmer is towed behind the tractor. It is not a standard for adjusting the ridges in the correct position.

In the present invention, a rod-shaped indicator is hung vertically on the front side of this point arranging machine,
It proposes a trimming machine that always indicates whether or not the trimming machine is performing trimming work in the correct position.

[Means for Solving the Problems]

 The gist of the present invention will be described with reference to the accompanying drawings.

The embankment device A is provided on the machine frame 1, and the rear ridge side of the embankment device A is matched with a desired ridge cross section. Is a arranging machine provided with the arranging board B of the above in the rear part of the machine frame 1,
A rod-shaped indicator 3 is vertically provided on the front ridge side of the machine frame 1, and the lower portion of the rod-shaped indicator 3 is formed of a flexible material such as rubber. The position of the lower end 3'of the flexible material is a sloped slope. The ridge trimming machine is characterized in that the height is set to be substantially the same as the lower edge of the ridge trimming plate B as the base of the ridge trimming machine.

[Action]

The operator directs the lower end 3'of the rod-shaped indicator 3 toward the base of the sloped slope of the ridge a to be made by the operator and advances the machine.

At this time, the designated position of the lower end portion 3 ′ of the rod-shaped indicator 3 is set as the base of the sloped ridge, and the height is set to substantially match the lower edge of the ridged plate B. Since the lower end portion 3'shows the correct trimming position of the trimming plate B at a close distance, the trimming is extremely excellent.

Further, even if the lower end portion 3'of the rod-shaped indicator 3 collides with the unevenness of the hard soil, since the lower portion of the rod-shaped indicator 3 is made of a flexible material, the rod-shaped indicator 3 bends and moves forward, which does not hinder the forward movement. .

Then, the embankment device A is used to embank the ridge a, and the ridge plate B provided at the rear portion of the machine frame 1 always arranges the ridge at the correct position.
