成された播種作業機が使用されていた。2. Description of the Related Art Conventionally, it was possible to perform direct sowing work using a rice transplanter equipped with a fertilizer application device. In other words, seeding is actually performed even if the seedling planting mechanism carries out a seedling planting movement by putting seed paddy in the fertilizer hopper of the rice planting machine with a fertilizer application instead of fertilizer and not placing the seedlings on the seedling platform. It was possible to supply seed paddy to the field by the fertilizer applicator if the fertilizer application and the rice planting work were carried out in the same manner as when the fertilization work and the rice planting work were carried out at the same time. In this case, the fertilizer is used to form a groove in the field and to supply seed paddy into the groove, and the fertilizer is arranged so that the groove is formed near the lateral sides of the planted seedlings or in the middle between the planted seedlings. Therefore, the plurality of seeding lines formed after the seed supply is arranged at irregular array intervals. Then, harvesters such as combine harvesters are designed to harvest crops obtained from multiple planting shoots planted at equal intervals by the rice transplanter, so when harvesting later by the harvester, weeding It becomes difficult to perform work, such as the tool easily plunges into the stock. Also, even if all fertilizers are located in the middle between planted seedlings and a plurality of sowing rows are formed at evenly arranged intervals, the plurality of sowing rows should be located laterally to the lateral center of the machine. You can do it by shifting the position. Then, when turning the aircraft at the end of the field and entering the next work run, the aircraft is operated in a manner different from the case of rice planting work, and the seeding line that can be created during the next work run is the seeding that was created during the previous work run. It becomes difficult to perform the work because the strips must be aligned so that they are lined up at a predetermined interval. For this reason, in the past, when actually performing direct sowing work, a seeding machine specially made for it was used.

It was at a disadvantage. An object of the present invention is to provide a plant that can perform both rice planting work and direct seeding work in a state where both those works and the subsequent harvesting work are easy to carry out.

0 is lowered to the working level and the vehicle runs. Then, the seedling planting apparatus 10 carries out seedling planting by the respective seedling planting mechanisms 12 ... After ground leveling by the grounding float 14, and the planted seedlings remain without being affected by digging up by the seeding tool 42. At this time, the seedling planting depth can be changed by adjusting the mounting angle of the float support arm 15 to the planting machine 11. Further, if each feeding device 20 ... Is switched to the above-mentioned fertilizer application and the powdered fertilizer is put into the tank T, the fertilizer application device 30 causes the seedling planting device 10 to plant a plurality of rows of seedlings near the lateral side of each seedling. Fertilization work in which fertilizer is embedded in mud can be performed at the same time.

回避できる。In carrying out the direct sowing work for supplying the rice seeds to the field, the seeding tool 42 is moved to the lowered use position by the elevating mechanism 60, and each feeding device 20 is switched to the seeding so as to store the seeds in the tank T. The seedling planting device 10 is lowered to the working level by running without planting the seedlings on the seedling platform 13 or by removing the seedling planting claws 12c of the seedling planting mechanism 12. Then, the seedling planting mechanism 12 performs the seedling planting motion to drive the feeding device 20, but does not actually plant the seedling, and the seeding device 40 causes the seeding devices 42 from the tank T by the action of the respective feeding devices 20. The seeds are fed to each of the fields, and a plurality of seeding operations are performed by each of the sowing tools 42. The rows are arranged at the same row intervals as the row for planting rice in the field. At this time, if the mounting angle of the float support arm 15 is adjusted by the planting depth adjusting lever 15a,
By changing the mounting height of the grounding float 14 with respect to the planting machine body 11 and by supporting the seeding tool 42 by being connected to the planting machine body 11, each seeding tool 42 ...
The depth of submersion in the field mud can be changed to change the seeding depth. Further, when any one of the plurality of seeding tools 42 ··· hits the stone or the clod, the seeding tool 42 automatically detects the stone or the clod due to the vertical shape of the lower end side portion 61c of the mounting hole 61a. It is possible to avoid the damage and deformation of the seeding tool 42 by overcoming.
