And between the fertilizer pipe 32 changes,
It is configured to absorb this vertical width. 1, the rotation of the ground drive wheel 40 is transmitted to the hexagonal cylinder shaft 53 by the fertilization chain case 43 in the embodiment of FIG. The inserted hexagonal fertilizer drive shaft serves as a common drive shaft for a plurality of sets of fertilizer applicators arranged on the left and right. Further, an urging rod 71 for urging the ground drive wheel 40 against the soil surface is protruded above the fertilizing chain case 43, and a spring receiving rod 45 receiving the spring of the urging rod 71 is horizontally rearward from the toolbar attachment body 19. It is projected to. It is also possible to sow other small-diameter seeds with the fertilizer, and for example, a crop such as corn and sorghum can be sowed simultaneously by one sowing device. 3 is a plan sectional view of the pressure-reducing / driving wheels 7 and the chain case 9, FIG. 4 is a side view of the chain case 9 with the case lid 9a removed, and FIG. 5 is a perspective view of the chain case 9 in an exploded state. It is. In the perforated-type sowing apparatus, spot sowing is possible, and it is necessary to change the rotation of the rotating perforated plate with respect to the rotation of the pressure-reducing / driving wheel 7 which takes power to set the point sowing interval. Although the seeding interval can be changed depending on the position of the seed hole in the rotating plate, the seeding hole changes its hole diameter depending on the type of seed. It is done by 47. Various sets of the front and rear sprockets 46 and 47 are prepared, and an operator selects and exchanges a desired combination. In this case, since the chain 50 is loosened or tensed, the chain 50 is set to a loose one,
If loose, use chain tension 4 to absorb this looseness.
8,49 and chain receivers 51,52 are configured. Further, a chain push 9c protrudes from the case body 9b. This prevents the chain push 9c from shifting left and right of the chain. The chain receivers 51, 52 project from the front and rear centers of the case body 9b, and the chain receivers 51, 52 also serve as female screw portions of fixing bolts of the case lid 9a. Then, the chain tensions 48, 49 are urged against the positions outside the chain receivers 51, 52. As shown in FIG. 5, the chain tensions 48 and 49 can be easily detached from the pivot shaft.

FIG. 6 is a rear view of the ground drive wheel 40 and the fertilizer chain case 43 for driving the fertilizer, FIG. 7 is a side view thereof, and FIG. 8 is a drive motor 54 instead of the ground drive wheel 40. And FIG. 9 is a side view of the same. In any case, the hexagonal cylinder shaft 53 is driven, and the hexagonal cylinder shaft 53 is driven.
A hexagonal fertilizer application drive shaft is inserted into the inside of the device, and the drive shaft is extended to the left and right, and all of the plurality of fertilizer application devices are driven by one set of drive devices. In the drive device by the ground drive wheel 40, a reverse rotation mechanism is configured by the reverse rotation gears 63 and 64 on the upper part of the fertilizer chain case 43, and the rotation of the ground drive wheel 40 and the rotation direction of the feeding roll 42a are reversed to scrape off. The position of the brush 60 is located at the rear of the fertilizer application device to facilitate cleaning. (F) Effects of the Invention Since the present invention is configured as described above, the following effects can be obtained. First, since the feeding case 2 is in an inclined state, and a rotating plate is disposed inside the feeding case 2, the lower portion of the rotating plate is a portion in which a certain number of seeds are seed holes. The high portion of the rotating plate can be a portion where a certain number of seeds inserted into the seed hole fall into the seeding pipe 16, and the seeds can be inserted into the seed hole and sowed. The drop to the pipe 16 can be performed at the height of the inclined rotating plate, so that the feeding performance of the rotating plate type feeding device can be surely improved. Second, the seed tank 1, the feeding case 2, and the seeding pipe 16
The seeding device configured according to the above is disposed obliquely rearward from the upper part of the grooved disk device 17, so that an extra space can be provided above the grooved disk device 17, and the toolbar mounting body 19 can be provided with a sufficient space. A space in which another fertilizer can be attached can be formed, and a mechanism that allows the fertilizer to be detachably attached to the toolbar mounting body 19 can be provided. Third, by providing a fertilizer in front of the inclined seeder, it is not necessary to arrange the seeder and the fertilizer in a tractor or a cultivator as in the related art. Because the working machine became longer in the front and back, the center of gravity of the tractor and the like did not move backward. In addition, since the fertilizer can be attached to the extra space formed in the seeding device, it is possible to easily change a machine having a fertilizer with or without a fertilizer.
