DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described in detail with reference to the drawings. The front sides of a pair of left and right frames 1a and 1b are connected by a mission case 2, and an engine 3 is connected to the mission case 2. In addition, the rear portions of the frames 1a and 1b are connected by the planted transmission case 4 having an L-shaped side view,
The base of the steering handle 5 is attached to the rear end side of the planted transmission case 4.

A seedling stand 6 is located above the steering handle 5 and is inclined so that the front side is lower, and is supported so that it can be moved left and right from the side of the planted transmission case 4 and the handle 5. It is configured to be connected to a reciprocating device on the side of the transmission case 4 and reciprocate left and right. 7.7
Is a planting tool, which is attached to the planting transmission case 4 by a crank and a swing arm, and is configured to divide and engage the seedlings from the seedling placing table 6 and carry and plant them on the soil surface.

Reference numeral 8 denotes a wheel, which is located at an intermediate portion between the frames 1a and 1b and is pivotally supported on a rear side of a chain case 9 which is pivotally supported about a drive shaft of the mission case 2. The chain case 9 is provided so as to be rotated by transmission, and the chain case 9 is configured to be vertically adjustable via a link 11 by a handle 10 on the rear end side of the vehicle body. 12a
12b is a ground level float, which extends rearward from both sides of the wheel 8, and its rear part is pivotally attached to the planted transmission case 4 via a bracket so that the front part moves up and down, and the front part is Hanging rods 13 and 13 on the frames 1a and 1b
It is mounted so that it can move up and down via.

The left and right fertilizer applicators 14 are fertilizer tanks 15a-1.
5b, feeding devices 16a and 16b, funnels 17a and 17b, transfer pipes 18a and 18b, groovers 19a and 19b, and the like, which are located on the left and right sides of the wheel 8, respectively, and the front and rear sides are the frame. Metal fittings 20a and 20 on 1a and 1b
It is supported by b. And this fertilizer tank 15a
Left and right fertilizer feeding devices 16a and 16b are integrally attached to the lower end side of 15b, and funnels 17a and 17b to which transfer pipes 18a and 18b are connected are provided below the feeding devices 16a and 16b. The groovers 19a and 19b are fixed to the leveling floats 12a and 12b so as to project lower than the lower surface thereof, and have a U-shape in a plan view, and the transfer pipes 18a and 18b intervene in the inside thereof. Is configured.

The transmission of the feeding devices 16a and 16b is constituted so that the feeding roll is rotated by a ratchet mechanism, and the ratchet levers 21a and 21b of the feeding device 16a and 16b are connected to the swing arm of the planting tool 7 and the rod 22a. -It is configured to be connected by 22b. Reference numeral 23 is a spare seedling placing table arranged above the wheels 8 and is used for the fertilizer tanks 15a and 15b.
It is constructed integrally with the lid.

Explaining the operation of the above example, first, when the fertilizer tank 15 is filled with granular fertilizer, seedlings are mounted on the seedling placing table 6 and each rotating portion is driven by the engine 3, the wheels 8 rotate. The left and right leveling floats 12a and 12b are propelled while being in contact with the soil surface of the paddy field. In addition, the seedling placing table 6 reciprocates left and right to supply the seedlings to the transplanting tools 7 and 7, and the transplanting tools 7 and 7 divide the seedlings and transfer them to the soil surface to be leveled by the leveling floats 12a and 12b. To do. on the other hand,
The left and right fertilizer feeding devices 16a and 16b of the fertilizer applicator 14 are driven from the swinging arm side of the transplanter 7 and 7 through the rods 22a and 22b, and the fertilizers in the fertilizer tanks 15a and 15b are fed little by little to the funnel 17a. 17b, and then the transfer pipes 18a and 18b are flowed down to make the grooving device 19a and 1.
At 9b, it is discharged into the ditch formed in the field. In this way, rice planting and fertilization are performed simultaneously, but according to this embodiment, the fertilizer tanks 15a and 15 of the left and right fertilizer applicators 14 and 14 are used.
Since b is divided into two parts to the left and right and located on both the left and right sides of the propulsion wheel 8, the front-rear balance of the machine does not fluctuate and the center of gravity does not rise even if the fertilizer is stored and becomes heavy. In this way, stable operation and propulsion can be performed, and it is difficult for the planting depth to change when planting seedlings.
