Description

[Detailed explanation of the idea] The present invention relates to a flooded direct seeding machine.

Conventionally, as shown in Japanese Utility Model Application Publication No. 54-142621, there has been a flooded direct sowing machine that continuously sows seeds by providing a seeding groove in the soil leveling body. Since the seeding groove was opened, muddy water overflowing into the seeding groove could not be drained out in an orderly manner, and there were functional problems such as the seeds tending to float and flow.

Therefore, the present invention has been devised to solve the above-mentioned problems.

Hereinafter, the present invention will be explained based on the drawings.

Figure 1 shows a plan view of a 6-row flooded direct seeding machine, in which an engine E with a sliding cover 6 underneath is installed at the front of the machine, and both transmission cases 7 on both sides of the machine are equipped with wheels. 8 and 8 are respectively mounted on axles, and three floats 2 which are used for leveling purposes are arranged in parallel at the center and both sides of the body approaching the wheels 8, and on both sides of the rear of each float 2 there is a notch that opens upward and downward and backward. 1
are notched in the longitudinal direction of the fuselage, and on the lower surface of the float 2 in front of each notch 1, groove-making protrusions 9 are formed as protrusions as groove-making devices, and on the side of the rear of each notch 1, soil is placed. A container 10 is installed, guard pipes 11, 11 are installed on the outside of both floats 2 on both sides, respectively, and a handle 12 is extended to the rear of the body.

Mounting frame 13 is located above the rear of each float 2.
A tank 3 having a lid 14 on the upper part is installed above the tank 3, and a roll chamber 3a is formed in the lower part of the tank 3 to communicate through a narrow communication port 15. At the top, a feed roll B with buckets 16, 16 attached alternately in a staggered manner on both sides of the periphery is mounted on a shaft, and the rear part of the feed roll B is installed so as to protrude outside the roll chamber 3a. A clutch operated by a knob 18 is interposed between a flexible shaft 17 driven from the E side so that the feed roll B can be rotated.

A shows the entire chute, in which both extending passages 19, 19 branch from the middle part in the vertical direction and extend downward, curved in an arc shape, and the discharge ports 4, 4 at the tips of each are connected to the notch 1. , 1 so that the rear part of the feed roll B looks into the chute A through an opening 20 formed in the front surface of the upper part of the chute A, and the upper part of the chute A is placed at the rear of the roll chamber 3a. , insert the butterfly bolts 21, 21 that pass through both sides of the upper part of the chute A into the screw holes 22, 2 on both rear sides of the roll chamber 3a.
2 to fix the upper part of chute A, but the entire chute A is attached to the front body A1 and the rear body A1.
The front body A1 is divided into two parts and joined together.
The rear body A2 is made dark black and the rear body A2 is transparent.

In addition, through holes 24 and 24 are provided on both sides of the flat plate portion 23, which is formed on the lower side of the entire chute A and spans between the upper portions of both the extending passage portions 19, 19.
are formed, and the through holes 24, 24 have the through holes 2
4 and 24, and a nut 25 is screwed into the base of the screw 5 with a spacing slightly larger than the thickness of the flat plate part 23. , the screws 5 are attached to the chute A so that they are locked and held, and the screws 5 are installed and configured so that they can be screwed into screw holes 26, 26 formed on both sides of the rear surface of the mounting frame 13, respectively.

Therefore, the upper part of chute A is attached with butterfly bolt 21,
21, when holding the butterfly head 5a and rotating both screws 5, 5, the lower part of the chute A can be adjusted by moving back and forth by the screw 5 and screw hole 26 being engaged. Thereby, the position of the float 2 can be adjusted along the longitudinal notch direction by slightly moving the discharge ports 4, 4 back and forth as shown by arrow A.

In the above description, the discharge ports 4, 4 have a structure that can be moved back and forth, but the discharge ports 4,
Of course, it is also possible to configure so that 4 can be adjusted in the left and right directions.

During work, each bucket 16 moves into the roll chamber 3a while the feed roll B rotates as shown by the arrow B.
The seeds inside are scooped out and released into the upper interior of chute A one after another while being carried around, and the falling seeds, as shown by arrow C, flow down inside both extension passages 19, 19 and from both discharge ports 4, 4. When the seeds are released into the notches 1 and 1 and thrown into the groove formed by the protrusions 9, the soil can be collected by the soil cultivator 10 and sowing work can be performed. Since the muddy water that overflows into the notch 1 can be well discharged from the rear, it is possible to sow the seeds without causing them to float and flow, and the excess muddy soil and muddy water can be discharged rearward to reduce the mud pushing pressure of the cultivator 10. Appropriate cultivation soil can be created by maintaining the soil at a fairly constant level.
Also, depending on the soil hardness of the field, the amount of water, etc., the position of the overflow in the notch 1 of the float 2 changes to the front when the soil hardness is soft or when the water volume is large, and to the rear in the opposite case. However, by adjusting the discharge port 4 of chute A in the front-back direction accordingly, the notches 1, 1 located in front of the overflowing position can be removed.
The seeds can be released into the container, thereby preventing the floating movement of the seeds.

Note that since the rear part of the chute A is transparent, it is possible to see through the fallen state of the seeds, and the chute A can be divided for cleaning.

In this way, the present invention has a notch formed in the longitudinal direction of the fuselage on both sides of the rear part of the float that opens upward and downward and backward, and a groove cutter is provided on the lower surface of the float in front of the front and rear notches. A soil cultivator is installed on the side near the rear of the notch, while a discharge port of a chute of a seed feeding device is positioned above the notch, and the position of the discharge port is adjusted along the front and rear notch directions of the notch. Because of this construction, the seeds fed by the seed feeding device can be passed through the chute through the lower discharge port through the notch at the rear of the float, and are reliably sown into the field. Since the muddy water can be well discharged from the rear, it is possible to sow the seeds without causing them to float and flow, and the mud pushing pressure of the soil pot can be maintained at a substantially constant level to form suitable soil.

Furthermore, by adjusting the position of the outlet of the chute along the front and back direction of the notch according to the field conditions,
It is possible to accurately discharge the seeds to a position ahead of the overflowing position in the notch without causing the seeds to adhere to the float, and this provides a special effect in that the seeds can be sown accurately.
