Description

[Detailed Description of the Invention] The present invention relates to a direct sowing machine that continuously sows a certain amount of seeds onto a field.

Conventionally, the technology used was to support the seed storage hopper on the machine body and provide a breakwater plate to fix the seeding tube (for example, Japanese Utility Model Publication No. 43-194).
However, the breakwater plate does not have the function of leveling the sowing surface and only allows the seeds to fall onto the sowing surface from above, which may cause the seeds to move after sowing. Since the seed storage hopper was provided in the machine body, it was difficult to bring the hopper and the seeding surface close to each other, and the seeding tube became long, making the seed feeding function unreliable.

In particular, since the front end of the breakwater plate was connected to the fuselage, it was necessary to connect a spring to the breakwater plate to support it horizontally, but the mud etc. that adhered to the breakwater plate kept it horizontal. was making it difficult.

The present invention solves the above-mentioned conventional drawbacks, and includes supporting a seed storage hopper on the upper part of the sowing frame, which is connected to the machine body so as to be able to swing back and forth, and attaching a float leveling body to the lower part of the frame. A spring that presses down the rear part is connected to the frame and inside the machine body, and by providing a seed storage hopper above the floating ground leveling body via the sowing frame, the hopper can be used to sow seeds in fields, etc., compared to conventional methods. The seeds can be appropriately and continuously dropped close to the surface, and the direct sowing operation that releases a certain amount of seeds to a set position can be stably performed, and the ground resistance when running is a force that lifts the rear part of the soil leveling body. In contrast, the spring can properly maintain the ground pressing force at the rear of the soil leveling body, and the spring can prevent the front part of the soil leveling body from descending, allowing safe seeding work. The aim is to provide an opportunity.

Hereinafter, one embodiment of the present invention will be described in detail based on the drawings.

The present invention is constructed as described above, and the seed rice, that is, the seeds made by coating the germinated rice with a mixture of lime peroxide and calcined gypsum, is filled into each of the hoppers 14, and the flooded fields are placed in the flooded fields after puddling. While the machine is running, seeds in the hopper 14 are directly sown in a fixed amount, one plant at a time. Pumped up outlet 3
4 to the seeding chute 35, and the chute 3
The seed rice released into the chute 35 is directly sown every two rows from the fork at the lower end of the chute 35.

In the case of direct sowing, the floats 16a, 16b, 16c
The protrusions 27 and 27 formed on the ridges scrape grooves in the field as the machine travels, and each float 1
While the seeding grooves 28.28 of 6a, 16b, and 16c are moving, the seed rice falling from the chute 35 is directly sown from the front end of the groove 28.28 into the cultivation groove, and the seed rice directly sown into the cultivation groove. The sowing grooves 28 and 28 are covered with soil by soil plates 29 and 29 provided at the rear of the sowing grooves 28 and 28.

The seed rice stored in each hopper 14 in this way is pumped out into each chute 35 by each feeding device 15, and is dropped into the grooves scraped by the protrusions 27, 27, and then removed from the soil plate. 29.29, the floats 16a, 16b,
An upward force is generated on each of the protrusions 27.27 of 16c and the soil plate 29.29 due to their ground resistance, and an upward force is applied to the rear part of the floats 16a, 16b, 16c, causing the rear part to This is pressed by the biasing force of the spring 23 to prevent the floating action and ensure direct sowing of seed rice.

Further, when the aircraft turns with the rear part of the aircraft slightly raised, the spring 23 acts on each of the floats 16a, 16b, and 16c, and an upward force is applied to the front part using the pin 11 as a fulcrum, and a downward force is applied to the rear part. As a result of applying a force in the direction, the front portion of the float 16at 16b* 16c is lifted, and the float 16a? 16 b, 16
c Avoid inconveniences such as forcing the front end into the soil,
This allows the aircraft to turn smoothly.

As is clear from the above embodiments, the present invention has a seeding frame 17at 17b connected to the machine body so as to be swingable back and forth.
The seed storage ho'/bar 14 is supported on the upper part of the y 17c, and the float leveling bodies 16a, 16b, 16c are attached to the lower part of the frame 17a, 17bt 17C,
The float leveling body 16a.

The seeding frame 17a is made by connecting a spring 23 that pushes down the rear parts of 16b and 16c between the frames 17at 17bt 17c and the machine body.

Float leveling body 16a via 17b and 17c.

By providing the seed storage hopper 14 above 16b and 16c, the hopper 14 can be brought closer to the sowing surface of the field etc. than in the past, and the seeds can be properly and continuously dropped, and a certain amount of seeds can be dropped. The direct sowing work of discharging to a set position can be performed stably, and the ground resistance during running acts as a force to lift the rear parts of the soil leveling bodies 16a, 16b, 16c, while the spring 23 16a, 16bt 16c The ground leveling body 16a can properly maintain the ground pressing force at the rear.

The spring 23 prevents the front portions 16b and 16c from descending, resulting in practical effects such as safe seeding work.
