Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a marking marker device for marking marker lines parallel to the seedling planting rows on the field during rice transplanting work.

[Conventional technology]

Generally, a rice transplanter is equipped with streak marker bodies on both the left and right sides, and when the rice transplanter is moved forward for rice planting work, seedlings are planted in the field on the unplanted side using the streak marker bodies on the unplanted side. Attach a marker line parallel to the attachment line, and then move the rice transplanter to the edge of the bank using the marker line.
The rice transplanter's running position is instructed when it turns 180 degrees and starts rice transplanting work. in this case,
In the conventional streak marker body, a bar-shaped streak marker piece is pressed and slid onto the unplanted field to form grooves, which serve as marker streak lines. However, muddy water flows into the groove created by a rod-shaped marker piece, so it easily disappears.

Therefore, as a prior art, Japanese Utility Model Application Publication No. 53-69324 discloses that two plate bodies with streaked marker bodies made almost perpendicular to the field are arranged so that the distance between them is directed toward the rear of the rice transplanter in plan view. It is proposed that the rice transplanter be arranged in a narrowed shape at the back, and that when the rice transplanter runs, the mud in the field will be piled up between the two plates to form marker lines.

[Problem that the invention attempts to solve]

However, the streak marker device of the prior art forms marker streak lines by scraping the muddy soil from the field together with muddy water using two plates and raising it up from the field. The mud that has been piled up in the field contains a sufficient amount of muddy water and is extremely prone to collapse, making the marker streak lines extremely unclear. This occurred significantly in

Moreover, if there is straw, grass, etc. scattered in the field, the straw, grass, etc. will not only get caught on the two plates and cause the mounded mud to collapse.
There were cases where it was not possible to form marker lines because straw and other debris scattered on the field obstructed the mounding up of mud.

The object of the present invention is to provide a muscle pulling marker device that solves these problems.

[Means to solve the problem]

In order to achieve this purpose, the present invention uses a striped marker body that is pressed and slides on the field during rice transplanting.
The band-like plate body is formed into an arched sled shape, and an incision groove extending in the longitudinal direction is provided at the lower end of the striated marker body to form two flat striated marker pieces. The both striation marker pieces are configured to have an inclined cross section so that the cross sections thereof are in an upwardly opening V-shape, and furthermore, the angle of the upward opening of the both striation marker pieces is set according to the angle of the upward opening of the both striation marker pieces. It is large at the front end and gradually becomes smaller toward the rear end.

[Functions and effects of the idea]

In this configuration, when the lower end of the striation marker body is pressed against the field, both striation marker pieces slide across the field. In this case, by configuring both of the striped marker pieces to have an inclined cross section so that the cross section of both of them forms an upwardly opening V-shape, the double striped marker pieces can be used to prevent muddy water in the field. Two grooves are formed while being removed to the outside, and ridges of mud are formed in the incision grooves between the two striped marker pieces.

Moreover, by configuring the upward opening angle of the both striped marker pieces to be large at the front end of the both striped marker pieces and gradually become smaller toward the rear end, muddy water in the field can be The ridges of mud that are sequentially removed to the outside by the pull marker pieces and are formed in the incision grooves between the two pull marker pieces are in a state where there is significantly less muddy water.

That is, in the present invention, two grooves are formed in the field by means of both lined marker pieces with an inclined cross section, while muddy water in the field is sequentially removed to the outside of both lined marker pieces, and in between, The method involves forming ridges using muddy soil with little muddy water, and making these ridges of muddy soil into marker streak lines.As in the past, muddy soil is raised from the field together with muddy water to form marker streak lines. Therefore, marker lines can be reliably formed even when the field is extremely soft.

Moreover, in the present invention, the strip marker body, which is equipped with both strip marker pieces at the lower end, is made into a band-like plate, and this is configured into an arched sled shape, so that it can be used to remove straw waste from the field. In addition to preventing grass, etc. from getting caught, it is possible to create two grooves in the field even when there is straw waste, etc. in the field. Even in such cases, marker lines can be reliably formed.
