Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a trimming machine for adjusting old thin ridges into a predetermined ridge shape.

[0002]

2. Description of the Related Art As a conventional arranging machine, the actual machine is Sho 57-1.
There is known a method in which the embankment on the ridge is continuously hit with a rectifying plate to be beaten and solidified as in No. 0483. This type of ridge trimmer has the drawback that vibration and noise are large due to the impact of strongly striking the ridge trimmer on the ridge face.

Further, as in Japanese Utility Model Laid-Open No. 60-57905, there is also known a rectifying machine which uses hydraulic pressure to elevate and lower the rectifying plate and tap the embankment. 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.

Further, the violent impact vibration of the hitting and pressurizing operation of the ridger, which is repeated in both cases, is transmitted to the support device of the tractor supporting the machine frame, not only making the driver uncomfortable but also damaging the tractor. It has a drawback that causes it.

SUMMARY OF THE INVENTION According to the present invention, one side of a machine frame is extended in a lateral direction, and a ridge and a repetitive pressurizing motion generating mechanism are provided at an end portion of the extension side so as to be far from a supporting device. The present invention relates to a rectifying machine that focuses on damping vibrations and prevents shocks and vibrations received by a ridged body that performs repeated pressurization operations from being transmitted to the tractor support device as much as possible.

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

The machine frame 3 is mounted on a supporting device I supported on the rear part of the tractor 37 via elevating arms 67 and 68, and the embankment device B, the ridge body C, and the ridge body C are repeatedly pressed. The repetitive pressurizing motion generating mechanism D to be provided is provided at the side end of the machine frame 3, and the ridge soil is piled up on the ridge surface by the embankment device B, and the rectifying body C repeatedly pressurizes and arranges the ridge, The machine frame 3 is formed to extend to the left and right, and the ridge body C and the repetitive pressurizing motion generating mechanism D are attached to the extended side end of the machine frame 3, and the ridge body C and the repetitive addition are repeatedly applied. The attachment position of the pressure motion generating mechanism D is changed to the machine frame 3

[0008]

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of the present invention will be briefly described with reference to the drawings showing an operation and an example of the embodiment.

The embankment device B provided on the machine frame 3 crushes the soil at the ridge and embanks it on the upper surface of the ridge a and the slope of the ridge a.

Since the ridge body C and the repetitive pressurizing motion generating mechanism D are provided at the extension side end of the machine frame 3 extended to the ridge a side, the ridge body C is provided.
Since the attached position of the repetitive pressurizing motion generating mechanism D is biased further than the support device I by the distance extending the machine frame 3 laterally, the impact and vibration generated by the repetitive pressurizing operation of the machine frame 3 is extended. The vibration at the free end is greatly attenuated as it reaches the support device I side of the machine frame 3, and the impact vibration transmitted to the tractor 37 is greatly reduced.
