Description

[Detailed explanation of the idea] The present invention relates to a float mounting structure for a seeding machine.

In other words, the main float and the auxiliary floats on both sides, each of which is equipped with a sowing device, have buoyancy and can quickly respond to the rice field and glide reliably and well, and also can perform multi-row sowing in a direct sowing method, so that it can be carried out suitably. It is something to do.

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

Figure 1 shows a plan view of the entire seeding machine, which is a submerged direct sowing machine, with two-wheeled double-wheeled wheels 1°1 and axles 2, 2.
are mounted on both sides of the rear of the mission case 3, and the engine E is directly connected to the front of the mission case 3, which is the front of the entire aircraft.
The handles 4, 4 connected to each other are constructed by extending slightly higher toward the rear of the fuselage.

In addition, the front end 5 of the wide main flow A that extends long in the front-rear direction between the two wheels 1 and 10 is bent upward, and both auxiliary floats a are arranged on both sides of the rear of the main flow A. The front end part 6 of a is also formed to bend and extend upward, and the lower part of the transmission case 3 and the main flow that hangs on the front side from the axle 2)
A compression type spring 7 is interposed between the upper front part of A and the upper part of the front part.

Main flow) 2 rear parts of A and both auxiliary flows) ata
Each of the sowing machines C is equipped with a roll 11 on which four packets 10 are disposed, which is mounted on a shaft at the rear of the lower part of a hopper 9 that stores the seed rice 8. The lower part of the drop tube 22 is fitted into the drop port 12 of each float, and the lower front part of each drop port 12 is provided with a groove 13. Form a protrusion.

The base 4a of the handles 4, 4 has a fulcrum pin 15 extending rearward from the support 14 fixed on the lower side of the handle 4, and the upper part of the support frame B fixed with a bolt 16 to the upper surface near the rear of the main flow A. The fulcrum shaft hole 17 in the front-rear direction is rotatably fitted into the fulcrum pin 15, and both connecting frames b, b, which are respectively connected to both ends extending on both sides of the support frame B, are connected to both auxiliary flows) a, Connected to a via pins 18, 18, balanced springs 19 and 19 are placed on both sides of the fulcrum bottle 15, and balanced springs 2 are also connected to both auxiliary flows a and a on both sides.
0.20, respectively, so that the axis center line of the fulcrum shaft hole 17 is parallel to the direction of movement of the aircraft and has an angle θ slightly inclined to the rice field 21, or is parallel to it. Configure it as follows.

The shafts 11a of the rolls 11 in each seeder C are connected to each other so as to be driven by flexible transmission shafts.

The seed rice 8 is made by coating sprouting rice with a mixture of lime peroxide and calcined gypsum, and can germinate even if it enters the soil.

When the operator grasps and operates the handles 4, 4, the two axles 1, 1 can be used to travel on the rice field, and the axis center line of the fulcrum shaft hole 17 that fits into the fulcrum pin 15 is aligned in the direction of movement of the machine. The main float Ai- and auxiliary flows a and a, which are towed by the support frame B, are parallel and are parallel or slightly inclined to the field surface 21, so they have good responsiveness to the field surface 21, and their buoyancy increases when flooded. Then, each float A, a, a slides on the rice field 21.

In addition, even if the wheels 1, 1 are tilted laterally due to unevenness of the tiller, etc., they rotate about the fulcrum pin 15 and each float A t
A + 8 can always ski in a normal posture without tilting against the rice field 21.

Grooving sections 13 of each flow A, a, and a form grooves on the rice field, and seeds are sown from each sowing machine C into the grooves.

In this way, the present invention has a main float button that is long in the front-rear direction and a sowing device installed on both auxiliary floats on both sides of its rear, and connects both sides of the support frame connected to the upper rear part of the main float to both auxiliary floats. The fulcrum shaft hole or fulcrum pin in the upper part of the support frame, which is rotatably pivoted to the fuselage side of both axles at the front of the support frame, is aligned so that the axis center line is parallel to the direction of travel of the aircraft and parallel to the circular surface. Alternatively, since the main float and both auxiliary floats, which are pulled by the wheels, have buoyancy and are configured so that they are slightly tilted forward, they can quickly respond to irregularities on the rice field and slide reliably and well, and always slide in a normal posture. The present invention has the feature that seeds can be reliably and satisfactorily sown by the direct sowing method without changing the planting depth from each float, and can be carried out suitably.
