Description

[Detailed Description of the Invention] The present invention relates to a soil cultivating device in a flooded direct sowing machine. In other words, the conventional culturing soil, for example,
As shown in No. 25482, etc., the soil-covering surface of the soil-covering body is formed by a single surface, and the structure is such that all the mud in the soil-covering position flows out to the trench side. In fields with deep water, an appropriate amount of muddy water flows out to the trench side, washing away the mud that had been collected to fill the trenches, resulting in the problem of not being able to properly cover the trenches with soil.

Therefore, the present invention solves the above-mentioned problems,
To provide a simple structure that allows smooth flow of muddy water during covering with soil, ensures and good covering of soil, and enables suitable implementation with a simple structure.

Next, the embodiment shown in the drawings will be described.

Figure 1 shows a side view of a 6-row flooded direct seeding machine, in which both wheels 8, 8 are arranged on both sides of the rear of the engine E, and both handle rods 9, 9 are extended to the rear. Each of the three floats A towed by this machine C has notches 3, 3 opened in the vertical direction and rearward and V-shaped in plane, respectively, on both sides of the rear part of each of the three floats A towed by the machine C. A slender groove member 4 is integrally formed on the lower surface of the float A located further forward in the front-rear direction, and a mount 1 is formed above each float A.
0 are connected by connecting rods 11, 11.

A hopper 12 is installed above each mount 10, and the lower part of a drop gutter 13 formed at the front lower part of each hopper 12 is connected to the lower seed storage chamber 13. Bucket 1 on the circumference
An opening 1 formed at the rear upper part of the seed storage chamber 13, in which the feed roll 15 equipped with the seed storage chamber 13 is rotatably mounted.
6 is aligned with the receiving opening 17 formed on the front surface of the upper part of the hanging chute 1, and the feeding chute 1
The two notches 3,
It is installed so that it faces downwards above the front part of 3.

A support metal 5 is installed on the upper part of the float, which is one rear side of each notch 3 in each float A, and the lower part of the support metal 5, which has an L-shaped side surface, is fixed to the upper part of the float with a stopper 19. A plurality of adjustment holes 20 are formed in the vertical direction in the upright portion of the support metal 5 that extends upward along the side surface of the notch portion 3. Reference numeral B denotes a culturing soil body, and the lower edge 7 of the plate-shaped culturing soil body B is arranged along the front-rear direction so as to approach the side surface of the notch 3. Further, the culture soil body B has a ridge line 23 that protrudes from the front part to the rear part and gradually becomes lower.
Above 3 is a slope 24 with a gentle slope, and above the ridge 2
3, a steep slope 6 is formed at the bottom of each soil so that the soil body B has a triangular cross section, and the upper part of the soil body B can be aligned with each adjustment hole 20. A hole 21 is formed, and a hole 21 is formed.
A bolt/nut 22 is detachably attached to the adjustment hole 20.

In addition, it is also possible to have a configuration in which the culturing soil bodies B are installed symmetrically on both rear sides of the notch portion 3, respectively.

During work, each bucket 18 of the rotating feed-out roll 15 scoops up the seeds in the seed storage chamber 14 and releases them into the feed-out chute 1, and the groove-making body 4 below the float A sliding on the rice field makes grooves. Then, the seeds falling from the outlet 2 pass through the notch 3 and fall into the trench, and then the soil body B covers the trench while cultivating soil, so that seeds can be sown.

In this case, since the lower edge 7 of the culturing soil body B is formed to have a high front and a low rear, it moves forward by cutting smoothly into the mud on the side of the trench, and the slope 6 It is possible to cover the soil by laying it down on the trench side.

Furthermore, when covering with soil, a ridge line 2 is added to the soil body B.
4, and a gentle slope 25 is formed above the ridge line 24, so that only the muddy water required for covering the trenches can be properly circulated and guided by the slope 6 of the culturing soil body B, especially in fields with deep water. The remaining mud and water can be flowed to the rear of the machine by the guiding action of the slope 25 without adversely affecting the soil covering.

In addition, by aligning the holes 21 of the soil body B with the respective adjustment holes 20 of the supporting metal 5 and changing the installation of the bolts and nuts 22, the lower edge 7 can be vertically moved as shown by imaginary lines A and B in FIG. By changing the position, the culturing soil body B can be adjusted up and down,
Thereby, the amount of soil covered by the culturing soil body B can be adjusted.

In this way, the present invention is constructed by forming a notch that opens vertically and backwardly at the rear of the float through which the lower end outlet of the seed feeding chute is exposed, and a groove-forming body protruding from the lower surface of the float on the front side of the notch. In the flooded direct seeding machine, a cultivating soil body is provided on one or both sides of the rear part of the notch, and the cultivating soil body has a ridge line that protrudes toward the cultivation groove side from the front part to the rear part and gradually becomes lower. A gentle slope is formed above the ridgeline, and a steep slope is formed below the ridgeline, so that the soil body has a triangular cross section, and the lower edge of the soil body is formed to have a triangular cross section. Since the front height and the rear are low in order to gradually lower the height from the front to the rear, the steep slope formed below the ridgeline of the soil can smooth the mud on the sides of the trench when covering with the soil. It is possible to move the soil to the trench position and cover the soil reliably and well, and in fields with deep water, the gentle slope formed above the ridgeline of the soil body prevents excess mud from having a negative effect on the soil covering. This has the remarkable effect of allowing soil to flow out to the rear of the aircraft, allowing for accurate covering of the soil as a whole.
