If the tank is provided wide to improve the efficiency of the above-mentioned spraying operation, a large storage space is required when not in use, which is inconvenient. The present invention
When the above-mentioned fertilizer sowing apparatus is not used, the width is reduced to make it compact.

[0004]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention relates to a sub-tank 32 provided with a feeding device 31 at a lower part before or after a main tank 30 provided with a feeding device 31 at a lower portion. The auxiliary tank 32 is disposed in the front-rear direction
The fertilizer sowing device is provided so as to rotate around 1 and fall in front of or after the main tank 30.

[0005]

Next, an embodiment of the present invention will be described. The seeding device 2 is attached after the traveling vehicle body 1 to form a seeding machine. It is to be noted that a fertilizer applicator 3 is attached to this sowing machine so that the fertilizer operation can be performed along with the seeding operation (FIG. 1).

The traveling vehicle body 1 is configured as follows. A main gear box 5 and a rear wheel gear box 6 are provided before and after the frame 4, and a pair of front wheels 7 and rear wheels 8 are mounted on both sides of each. The engine 9 is mounted on the frame 4,
The front wheel 7 and the rear wheel 8 are rotated on the cultivator of the paddy field by the power to move the traveling vehicle body 1. A seat 10 is provided on an engine 9, and when an operator operates a steering wheel 11 in front of the engine 9, the front wheels 7 are steered to change the course of the traveling vehicle body 1.

A column 12 extends upward from the frame 4, and both ends of a pair of parallel links 13 are rotatably attached to this and a subsequent lifting frame 14. A hydraulic cylinder 15 is attached to the frame 4, and its piston rod 16 protrudes obliquely rearward and upward, and its tip is connected to an arm (not shown) integral with the upper link 13, and a pump (not shown) ) Supplies the discharged oil to the hydraulic cylinder 15, the piston rod 16 protrudes and the elevating frame 14 rises. When the oil is confined in the hydraulic cylinder 15, the elevating frame 14 stays at that height and the oil is removed. Tank (not shown)
, The piston rod 16 is pulled back and the lifting frame 1
4 is made to descend.

[0008] The seeding apparatus 2 is configured as follows. A work machine frame 17 is detachably provided on the lifting frame 14. That is, the V-shaped receiving portion 14 at the upper end of the lifting frame 14
After the upper end of the work machine frame 17 is hung on the a, the two are fixed by pulling the hook 18 together, and when the hook 18 is released, the work machine frame 17 is lifted by the lifting frame 14 so that both can be removed. ing.

A sub-frame 19b is arranged on the left and right of the main frame 19a to form a frame 19 (FIG. 2). A pair of supporting plates 2
0 extends from the inner end of the sub-frame 19b toward the main frame 19a,
0 and the main frame 19a are rotatably connected by a shaft 21 so that the sub-frame 19b is positioned on an extension of the main frame 19a or the sub-frame 19a
b stands up at the end of the main frame 19a.

A box frame 22 is fixed to the center of the main frame 19a,
This is attached to the lower part of the work machine frame 17 by a rolling shaft 23, and both ends of the frame 19 swing up and down. Five support arms 24 extend obliquely downward from the box frame 22, the main frame 19a and the pair of sub-frames 19b, and the rear ends of the respective floats 25 are swingably attached to the respective protruding ends by pins 26. Five link arms 27 extend obliquely forward and downward from the front portion of the central support arm 24 and the pair of sub-frames 19b, and the front portions of the respective floats 25 are supported by the long holes of the links so as to be movable up and down. When the float 25 slides on the muddy surface of the paddy field as the traveling vehicle body 1 moves forward, the float 25 swings around the pin 26.

Each float 25 has a front portion projecting left and right, and a pair of seeding and fertilizing device 29 is fixed to the rear of each overhanging portion. On the mud surface, 10 seeding grooves and fertilizing grooves are made. The lower part of the main tank 30 is formed in six valleys 30a arranged side by side, and a feeding device 31 is provided below each valley (FIG. 3). A pair of auxiliary tanks 3
The lower part of each 2 is formed in two side-by-side valleys 32a, and a feeding device 31 is provided in each valley 32a. The main tank 30 is arranged on the main frame 19a and is fixed thereto by a pair of supporting legs 33. The sub tank 32
Each sub-frame 19b is disposed on the outside of the main tank 30 and includes a support leg 34 and a support plate 35 extending outward from the support leg 34.
It is fixed to. When the sub-frame 19b turns around the shaft 21 as described above and stands up, the outer float 2
The auxiliary tank 32 is turned so as to fall down after the main tank 30 by rotating together with the main tank 30.

As is well known, each feeding device 31 rotates a feeding rotor having a feeding groove on the outer periphery by being driven by a transmission shaft 36, and the rotation causes the seeds (seed rice) in the main tank 30 and the sub tank 32 to rotate. ). The fed-out seeds are guided to the above-mentioned sowing device 28 by the respective flexible tubes 37 and sowed in the sowing grooves. The transmission shaft 36 below the main tank 30 and the transmission shaft 36 below the sub-tank 32 are connected by a detachable universal joint, and can be removed when the sub-frame 19b is bent as described above. In addition, the power of the engine 9 is guided to the transmission box 39 by the propeller shaft 38,
The rotation is transmitted to the transmission shaft 36 using a well-known crank or ratchet.
Can be configured to communicate to

The fertilizer applicator 3 is configured as follows. The fertilizer tank 40 is fixed to the upper part of the support 12 horizontally long. This fertilizer tank 40 has ten valleys 40 at the bottom.
a are provided side by side, and a feeding device 41 is provided below each valley 40a, so that the fertilizer in the fertilizer tank 40 fed by the feeding device 41 flows into the middle of a pipe 42 thereunder. An air chamber 43 is arranged in front of the pipes 42 so that air blown from the blowers 44 blows out to the respective pipes 42 from the front.
The respective pipes 42 and the fertilizer application device 29 are connected by a flexible tube 45, and the fertilizer that has flowed into the pipe 42 is sent to the fertilizer application device 29 by the wind to be sprayed on the fertilization channel. It is made like this.

Seeding cropper 28 and fertilizer cropper 29
After that, a backfill plate may be provided to fill back the seed furrow and the sowing furrow to which the seeds and the fertilizer have been sprayed. The delivery rotor used for the delivery devices 31, 41 can be configured as shown in FIG. That is, the fixed rotor 46
Are fixed to the transmission shaft 36. On the outer periphery of the fixed rotor 46, a plurality of fertilizer application grooves 46a opened to the right and a seeding groove 46b extending to the left from this are formed. And the fertilization groove 46a is formed deeper and wider than the seeding groove 46b. A movable rotor 47 is disposed on the right of the fixed rotor 46 and is configured to be movable left and right. The same number of projections 47a as the fertilizing groove 46a protrude leftward from the moving rotor 47, and slide in the fertilizing groove 46a by the above-mentioned left and right movement. Then, when the movable rotor 47 is moved to the end to the left, the fixed rotor 46 has all the fertilizing grooves 46a closed by the projections 47a, and only the seeding grooves 46b remain on the outer periphery. The one in this state is used as a feeding rotor of the seeding apparatus 2. Further, the moving rotor 47 is moved rightward from the above position. Then, the fertilizing groove 46 is formed on the outer periphery of the fixed rotor 46.
"a" appears, and the width thereof increases in accordance with the amount of movement, and the amount of fertilizer fed out increases. This is used as the feeding rotor of the fertilizer application device 3. As described above, according to the above configuration, there is an effect that a single rotor can be used for the seeding device 2, the fertilizing device 3, and the like.

[0015]

As described above, according to the present invention, when not in use, the end of the tank falls down inside, and the width of the tank is reduced to make the tank compact.
