Rear wheel support case 17. 17 is transmitted from the transmission case 1O via rear wheel transmission shafts 19, 19 provided exposed on the left and right sides of the vehicle body.

Pods 30 are placed over these chassis. And an engine room 3l where the engine 12 etc. are stored.
A driver's seat 32 is installed above the vehicle, and a steering wheel 35, hydraulic planting lever 36, etc. are attached to a steering post force bar 34 that projects upward from the front end of the vehicle body. In the link device 3, an upper link 41 and a lower link 42 are movably supported by a support frame 40 erected on the horizontal pipe 7, and a connecting frame 44 is provided at the rear end of these two lower links. It is installed. And this connecting frame 44
A working machine part 4 is mounted on the machine so that it can roll. A hydraulic cylinder 47, which is a driving means of the link device 3, has a portion 47a pivotally attached to the back surface of the engine stand 12a, and a piston rod 47b integrally installed from the base of the L link 41. It is connected to the tip of the arm 48. When this hydraulic cylinder 47 is expanded or contracted, the connecting frame 45 is moved up and down while being maintained in a substantially constant position.
The work equipment section 4 attached to this can be raised and lowered. The working machine part 4 serves as a rice transplanting device, and includes a transmission case 70 that transmits power from the traveling vehicle body side via a PTO shaft (not shown).
In front of the transmission case, there is provided a seedling stand 7l inclined so that the front side is in the second position, and two sets of planting rods 72 per row. The mounting table 7l reciprocates left and right to supply bacteria on the table one plant at a time to a predetermined seedling outlet, while the planting rod 72 moves up and down while drawing a predetermined trajectory to supply the bacteria to the seedling outlet. The supplied seedlings are held in the planting claws 72a provided at the tip of the planting rod and planted in the field. In addition, when the l\1/kaidai 7l reaches the end of the left and right travel and finishes supplying the seedlings for l horizontal rows to the outlet 14, the belt-type seedling feeding device 74 operates to feed the seedlings in one row. Move downward by the amount.

Further, the fertilizer application system 'ti80 is formed by a fertilizer tank 8L that stores fertilizer, a feeder 82 that feeds out the fertilizer in the fertilizer tank downward, and a groove device 94 that will be described later to feed the fertilizer fed out from the feeder. The fertilization pipe 83 is provided with a fertilization pipe 83 that leads into a fertilization groove in the field. The main body consisting of a fertilizer tank 8l and a feeder 82 is provided at the rear of the cockpit 32, and the lower end of the hopper 82a of the feeder is connected to the fertilization pipe 8.
It faces the front end of 3. The fertilizing pipe 83 extends rearward from there and then hangs downward along the back (front) surface of the seedling stand 71, and has a fertilizing port 83 facing the fertilizing groove at its lower end.
A is provided. Further, the engine room 31 is provided with a blower 85 that sucks hot air within the room and blows it into the front end of the fertilization pipe 83. Figure 2 is an electrical circuit diagram of this blower 85, in which 86 is a battery, 87 is a relay, and 88 is a sensing switch. The detection switch 88 is a work start sensor that detects an operation that is inevitably performed prior to the start of planting, and the one shown in the figure is provided along the rotation path of the upper link 41, and is installed when the link device 3 is moved from the raised position. When it begins to rotate to the lowered position, the prower 85
is turned on. That is, the operator presses the hydraulic planting lever 36.
Since there is a slight delay (approximately 2 seconds) between when the link device 3 starts moving downward by operating the link device 3 and when the planting work is performed, the blower 85 should be operated in advance before starting the planting work. As a result, appropriate air is already being blown into the fertilization pipe 83 when planting begins. Therefore, there will be no unfertilized plots where fertilization is not applied before planting begins, and no shortage of fertilization will occur. Further, by discharging the hot air inside the engine room 3L to the outside by the blower 85, the inside of the engine room is prevented from becoming high temperature, and the engine efficiency is also improved. In addition, as a work start sensor for detecting the operation at the start of planting, in addition to the method of detecting the operation of the link device N3 as shown in the illustrated example,
The switch may be turned on due to the operation of the hydraulic planting lever 36. In short, it is only necessary that the blower 85 is configured to start operating before the actual planting and fertilizing operations are started.

A center float 90 and a pair of left and right side floats 9f and 91 are pivotally mounted on the lower side of the transmission case 70 so as to be able to rotate vertically. A hydraulic valve 92 of a hydraulic cylinder 47 is installed vertically from the bottom of the connecting frame 44. center float 7
This valve 92 is driven by the vertical movement of the front end of the valve. When the float moves upward, the hydraulic valve 92 is driven in the direction of extending the hydraulic cylinder 47, and the working machine portion 4
increases. Further, when the float moves downward, the valve 92 is driven in a direction to contract the hydraulic cylinder 47, and the working machine portion 4 is lowered. A trencher 94, . . . for forming a trench for fertilization in the field is attached to each float in a manner corresponding to the planting position. [Effect of the invention 1 As explained above, the fertilizing device of the fertilizing field M machine according to the present invention uses a blower to blow air into the fertilizing pipe, and forces the fertilizer in the pipe from the feeding machine side to the fertilizing port side. Since the fertilizer is conveyed in a fixed manner, even if the fertilization pipe is long, the fertilizer can be applied reliably without clogging the pipe. Furthermore, since the blower starts operating at the time of operation for starting planting, it is possible to prevent the occurrence of unfertilized areas and insufficient amount of fertilizer at the time of starting planting.
