Description

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

In other words, each float can run while sliding on a circular surface, allowing seeds to be sown directly onto the rice field from each sowing machine.Especially, even if the wheels are tilted due to unevenness of the tiller, each float 1 and the sowing machine can be planted on a circular surface. To provide a seeding machine capable of maintaining a normal position against the ground, ensuring a constant planting depth, and driving each seeding machine effortlessly and reliably to ensure good sowing.

The embodiments shown in the drawings will be described below.

Figure 1 shows a plan view of the entire seed sowing machine, and the seed sowing machine is a flooded direct sowing machine. 3 on both sides of the rear,
Engine E is directly connected to the front part of transmission case 3,
A handle 4, 4, which is connected to a base 4a, 4a at the rear end of the mission case 4, is configured by extending slightly higher toward the rear of the fuselage.

The main flow that extends in the front and back direction between the side wheels 1 and 1)
Small auxiliary flows 1-a and a are arranged parallel to each other on both sides of the rear part of A, and a compression spring 5 is interposed between the front upper surface of A and the lower part of the transmission case 3, and the main flow Flow) Two places on the left and right at the rear of A, and auxiliary flow)
Drop ports 6 are formed in the rear portions of a and a, respectively, penetrating in the vertical direction, and a groove portion 7 is formed protruding from the lower front portion of each drop port 6, and both sides of the groove portion 7 are formed on both sides of the lower portion of the drop port 6. Mud prevention plate portions 7a, 7a are formed at the rear.

A support frame B is provided with a fulcrum pin 9 extending rearward from a support metal 8 fixed to the lower part of the base 4 a of the handles 4 , 4 on the 4 a side, and fixed with a bolt 10 to the upper surface of the main flow A). pipe-shaped both end portions 11. whose upper portions are rotatably fitted onto the fulcrum pins 9 and which extend to both sides of the support frame B;
11 is a connecting frame b.

One end of b is slidably inserted, and the other end is removably attached and fixed using 12.12.
Both auxiliary flows 1-a, fixed frame 13.13 on the upper surface side of a and connecting frame b, the other end side of b are connected to pin 14.13.
14, and a connecting frame b, which is rotatably connected to the fulcrum pin 9 and has balance springs 15, 15 on both sides of the fulcrum pin 9, and a connecting frame b.
, b and the auxiliary flows a and a, respectively, with balance springs 16 and 16 interposed between them.

C is a sowing machine, and each sowing machine C has two packets 18 at the rear of the main flow (A) and one at the auxiliary flow (A). The arranged rolls 19 are mounted on an axis, and the packets 18 can scoop up the required number of rice seeds 20 from the lower part of the hopper 17, raise them, and release them directly into the drop tube 21. It is configured so that it fits into the

A transmission part 23 having four drive shafts 22 at the rear is installed in the upper front part of the mission case 3, and the extending end of the shaft 19a of the roll 19 in each sowing machine C and each drive shaft 22 are connected to each other. Both ends of the flexible transmission shaft 24 are configured so that they can be detachably connected.

FIG. 10 shows another embodiment, in which the lower center of a support frame B constructed in the same manner as in the previous embodiment is fixed to the main float A, and both ends are fixed to both auxiliary flows a and a by bolts 25, respectively. There is.

FIG. 11 and FIG. 12 show still another embodiment, in which a mud trap prevention plate 7a is provided below the drop port 6 of each float.
, 7a, and the front portions of each are fixed to both sides of the groove portion 7 with screws 26.

The seed rice 20 is made by coating sprouting rice with a mixture of lime peroxide and calcined gypsum, and can germinate even if it enters the soil.

Therefore, the operator holds and operates the handles 4, 4, and the side wheels 1, 1 allow the main float A and both auxiliary floats to travel on a circular surface.
A slides on a circular surface, but even if the left and right wheels 1, 1 tilt laterally due to the unevenness of the tiller, the support frame B rotates around the fulcrum pin 9 and each flow (A, a, A can always slide in a normal position while adapting to the field surface, and even in that state, each seeding device C can be driven easily by the flexible transmission shaft 24.

On the rice field, the groove making section 7 of (Customer Flow) A, a, a makes four grooves, and each sowing machine C releases paddy seeds 20 at regular intervals and falls into the groove from the drop opening 6. The seeds are sown in a state in which mud buildup is prevented by the mud buildup prevention plate parts 7a, 7a.

In this way, the seeding machine of the present invention has at least the outermost seeding machine C of the plurality of sowing machines C supported by the floats A, a, and H connected to the machine body equipped with the wheels 1 and 1. The supporting float parts a, *'a are connected to the aircraft body so as to be vertically swingable, and the float part a, which is vertically swingable, is
, a flexible transmission shaft 24 is connected to the seeding machine C supported by the machine body.
Since the structure is configured so that power can be transmitted to each of them, it is possible to directly sow multiple rows of seeds in a circular manner from each seeder while sliding the float in a circular surface, and in particular, even if the wheels are tilted due to unevenness of the tiller, etc. The float parts a, a supporting the sowing device C arranged in the rice field can be maintained at a normal position with respect to the rice field surface without floating up from the rice field surface or being pushed deeply into the field surface, thereby ensuring that the planting depth is constant, It has the characteristics of being able to drive each seeding device effortlessly and reliably, and ensuring good seeding.
