DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention removes weeds in a field that has been plowed after harvesting grain culms, and simultaneously buries the weeds in soil while scratching the surface shallowly. The present invention relates to a weeding device in a simultaneous weeding and sowing machine, in which seedlings are planted on a weeded soaked surface.

[0002]

2. Description of the Related Art Conventionally, rice planting is generally performed by cultivating a field after harvesting grain culms with a tractor or the like, and a few days before planting, the entire cultivated layer is scraped and seedlings are planted in the slashed field. I am trying to. However, in this method, it is necessary to separately scrape the entire tillage layer on the plowing work, and a great deal of labor is required. Japanese Patent Application No. 185911/1992 proposes a method in which a seeder is provided so that the surface layer of a plowed field is shallowly scratched and seedlings are simultaneously planted on the scratched portion.

[0003]

When the above-mentioned planting machine is used, the scraping work is omitted, which greatly contributes to labor saving of agricultural work, and the lower layer is kept in a plowed state because of the shallow scratching layer. There are many voids in the soil, the supply of oxygen to the roots is good, and the growth of seedlings is good.However, if there is a period between tillage and planting, plowing When various types of weeds thrive on the surface of the layer and scratch the plowed surface in this state, soft or small weeds are scraped off by the rotating action of the scraping rotor, and are removed into the mud. Although it is pushed in, there is a problem that hard-rooted ones and large ones are not completely buried in the mud, and the weeds are revived and hinder the growth of planted seedlings a little after planting.

[0004]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention is to arrange a plurality of plantings at the rear of a traveling body at a lateral interval, and to form a plurality of these plantings. A fork rotor driven by forcible rotation is horizontally mounted on the front portion, and a mowing mechanism is provided at a front portion of the fork rotor at a predetermined interval from the fork rotor. By doing so, weeding is cut and weeded at the same time as weeding, thereby solving the above-mentioned problem.

[0005]

[Action] After flooding the cultivated field to soften the soil,
Before planting, the flooded water is allowed to fall so that there is almost no water on the surface of the field. When the aircraft is advanced in this state, the weeds that grow in the field scene by the driving of the mowing mechanism are cut off from the root thereof, and the surface soil is stirred and crushed and leveled by the rotation of the scraper rotor. As we grow, weeds are pushed into the mud that has been scraped and weeded. In this way, a plurality of rows of seedlings are planted on the soil surface which has been scraped by weeding by the operation of each planting body.

[0010] The field where the rice was harvested is plowed by a tractor or the like in the fall or, depending on circumstances, in the following year, but in order to improve the supply of oxygen to the field and increase the soil quality, it is necessary to plant the rice at the time of planting. It is desirable to cultivate as early as possible. However, if there is a period between tillage and rice planting in this way, various weeds will thrive on the surface of the field during this period, and if they do not become completely buried in the soil at the time of scratching, the weeds will be revived after a while Furthermore, this will propagate and hinder the growth of the planted seedlings. When planting seedlings in a field where weeds have flourished after plowing,
Before the planting, the field is flooded and the soil becomes soft after two or three days or more, and the water in the field is drained on the day before planting, etc., so that the surface of the field is almost free of water. . Thereafter, the simultaneous sowing planter of the present invention is introduced into the field, and the mowing mechanism 24,
When the substituting rotor 15 and the planting device 9 are driven and driven, the cutting mechanism 24 cuts the weeds on the surface of the field from the root, and the cut weeds pass through the cutting blade 26 and rearward. To fall on the ground. After that, the rotor was replaced
15 rotates and advances in a state of penetrating the soil shallowly into the soil while rotating. The rotating action exudes the water contained in the soil to agitate the soil to form a muddy soil, and cut the cut weeds into the muddy soil. The seedlings are buried in the ground, and the surface is substantially flattened. Then, several seedlings are planted by the planting body 11 on the mud surface completely flattened by the leveling float 12. It is something to plant. At this time, in order to change the cutting height and the cutting depth according to the conditions of the field and the type of weeds, etc., and to increase the cutting and cutting effect, the cutting mechanism 24 and the cutting rotor are used.
It is convenient to adjust up and down 15 individually or together.

[0011]

According to the present invention, a plurality of planting bodies 11 are disposed at the rear of the traveling body 1 with a space therebetween in the lateral direction, and the front part of these planting bodies 11 is forcibly driven to rotate. Scraper 15
And a mowing mechanism 24 is provided in front of the scraping rotor 15 at a predetermined interval from the scraping rotor 15, so that the mowing mechanism 24 is placed before the scraping. Weeds that thrive in the field are harvested from their roots without fail,
Since weeds are buried in mud by the rotation of 5, weeds can be suppressed in the field after planting, and seedlings can be satisfactorily grown. Also, even if the foliage of the weeds after cutting is not completely buried in the soil, the roots are cut off and do not resuscitate, and serve as organic fertilizer to promote the growth of seedlings. Further, the construction is extremely simple and can be provided at a low cost, and at the same time, weeding, substituting, planting and multiple operations can be performed at the same time, and the working efficiency is further enhanced.
