Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a construction of a coulter for scraping the surface of an old ridge in a ridge coating machine and filling the soil in a portion where the soil has been scraped up.

[0002]

2. Description of the Related Art Conventionally, when a ridge coater is towed to the rear of a tractor and a ridge coater is used to perform ridge coat work, the pretreatment rotary provided at the front of the ridge coater scrapes soil on the ridge. ,
Scraping the ridges and slopes of old ridges in the soil gathering rotary provided in the rear part, and raising the soil on the ridges, so that the ridge surface is compacted by the ridge orthopedic plate with a vibrator provided in the rear part, A rear coulter was provided in the rear part of the earth-moving rotary, and the part scraped off by the earth-moving rotary was backfilled from the side with the rear coulter.

[0003]

When the pretreatment rotary is provided as in the prior art, the structure for driving the rotary and the structure for adjusting the height become complicated, and the apparatus itself becomes large and the cost increases. In addition, if a rear coulter is provided, the ridge coating machine receives the force in the rotational direction and becomes slanted in the front-rear direction due to traction resistance, the ridge molding position shifts, and not only the ridges cannot be accurately formed, but also the viscous solidification force becomes insufficient. , It could cause water leakage.

[0004]

In order to solve the above-mentioned problems, the present invention is mounted on a rear part of a tractor, scrapes the surface of a field ridge and an old original ridge, and scrapes the ridge on the ridge to form a ridge surface with a ridge shaping plate. In a ridge coater for coating and hardening, a support arm is projected forward from the front part of the main frame of the ridge coater, a front coulter is attached to the support arm, and a support is projected rearward from the rear part of the other side of the main frame. A rear coulter is attached to the rear portion of the support body, and the front coulter is arranged in front of the end of the earth gathering rotary, and the rear coulter is arranged behind the other end of the earth gathering rotary so that the soil flows inward.

[0005]

By using such means, when the ridge coating machine is moved forward to perform the ridge coating work, the original ridges on the upper surface of the ridges are scraped off by the front coulter and the soil is brought to the machine side, and the soil lining rotary rotates the original ridges. The soil of the field scene at the slope and the edge of the field was scraped up, and the scraped soil of the field scene was brought into the recess after scraping by the rotary coulter by the rear coulter. At this time, the load applied to the front coulter and the rear coulter was opposite. As a result, the moments cancel each other out, preventing the posture from being disrupted.

By arranging the front and rear coulters so that the working directions face each other in this way, in the conventional case, since only the rear coulter was used, the ridge coater exerted a force to rotate due to its resistance. At the time of work, the front coulter 39 generates a clockwise moment about the lower link pivotal support on the right side of FIG. 3, and the rear coulter 42 generates a counterclockwise moment, which cancel each other out. It was possible to suppress the rotational force of the ridge coater during work.

That is, since it is configured as in claim 1, it becomes possible to scrape off the soil and grass on the original ridge with the front coulter, and the cost can be reduced with a simpler configuration than the configuration with the pretreatment rotary. The reaction force when the front coulter scrapes and the reaction force when the rear coulter scrapes are in opposite directions, the moment is canceled, the steering balance is improved, the straightness is increased, and the ridge molding becomes clean and accurate. It was.

Further, since the direction of the front coulter can be adjusted as in claim 2, it becomes possible to adjust the scraping amount and width, the resistance when towing, etc., and the ridges can be formed according to the ridges and fields. It was
