The rotating shaft of 0 is supported by a bearing. The groove-making disk 10 is composed of two wedge-shaped stainless steel disks that are in close contact with each other at the front, and a sowing guide pipe 20 is installed in the wedge-shaped widening portion at the rear of the groove-making disk 10. It is embedded. Further, the fertilizing guide pipe 19 arranged in the front part of the sowing guide pipe 20
The fertilizer is placed on the outside at a position protected by a scraping plate 41, and the fertilizer is dropped thereon.

Further, a soil covering disk 11 is protruded and supported from the roller frame 36 behind the seeding section of the groove cutting disk 10. The soil covering disk 11 lightly covers the seeds sown in the grooves made by the wedge-shaped groove cutting disk 10.

Further, a support rod 12a protrudes from the roller frame 36 to support the soil covering roller 12.

The soil covering roller 12 is configured to have a width that covers both the fertilization position and the sowing position, and the soil covering roller 12 compresses the fertilizer and seeds in the furrow.

In the above configuration, the groove making disk 10 and the soil covering disk 11 attached to the roller frame 36
The soil covering roller 12 moves up and down by freely rotating the parallel links 24 and 23 according to the unevenness of the soil surface, so even if the body of the tractor T moves up and down,
This allows the seeding depth to be constant.

On the other hand, since the upper hopper and feeding device are fixed to the mounting beam 8 and do not follow the unevenness of the soil surface, the bellows rubber 17 is placed between the feeding device and the roller frame 36. , 18 are interposed to make it possible to absorb changes in the gap between the feeding device section and the roller frame 36 section.

Next, the configuration of the grounding wheel 9 that obtains the driving force of the fertilizing and seeding machine of the present invention will be explained.

The grounding wheel 9 is connected to the drive frame 38 by the feeding shaft 7.
It is pivoted using the pivot axis. and a chain case 47 between the rear end of the drive frame 38 and the ground wheel 9.
A guide rod 21 and a biasing spring 22 are interposed between the ground wheel 9 and the soil surface to keep the grounding ring 9 in contact with the soil surface at all times.

The rotation of the grounding ring 9 causes the feed shaft 7 to rotate via the chain in the chain case 47. The feeding shaft 7 has a hexagonal shape, and as the fertilizing and seeding unit slides left and right on the mounting beam 8, the fertilizing feeding device A can slide left and right on the feeding shaft 7. It is structured as follows.

The fertilization feeding device A is a fertilization and seeding frame 58.
It is fixedly installed at the rear end, and the fertilizer feeding device A
The sowing and feeding device B is attached to the rear surface of the seeding machine via right and left one-touch fittings 30, 30.

The above is the overall configuration, and then Figures 3 and 4
The configuration of the feeding device and the hopper section will be explained based on FIG. 5.

A fertilizer feeding device A is installed at the rear end of the fertilizer seeding frame 58, which allows the top of the mounting beam 8 to be adjusted left and right.
is fixed.

Then, the sowing and feeding device B is attached to the rear end of the fertilizing feeding device A via one-touch mounting tools 30, 30. Therefore, the sowing feeder B is not directly fixed to the drive frame 38, but is attached to the fertilizing feeder A with the one-touch mounting tool 3.
It is supported only by fixing it with 0.30 mm.

Fertilizer dispensing device A is located in the central dispensing case 5.
6, a feed roll 5 is rotated, and fitting holes 5 are formed at several places on the circumference of the feed roll 5.
A is opened. The feeding roll 5
As the fertilizer hopper 1 rotates, the fertilizer flowing into the feeding case 56 from the lower end of the fertilization hopper 1 is collected into the insertion hole 5a, and any fertilizer that exceeds the capacity is scraped off by the scraping brush 33. As the feed roll 5 rotates downward, the fertilizer in the insertion hole 5a is discharged from the bottom side of the feed roll 5, collected by the guide funnel 60, and collected by the bellows rubber 1.
It will be put in within 7 days. A fertilization guide pipe 19 is arranged below the bellows rubber 17, and the fertilizer that falls into the fertilization guide pipe 19 is guided to the side of the groove-cutting disk 10 and fertilized.

The feeding roll 5 is driven by the above-mentioned grounding wheel 9.
Since the feed-out shaft 7 rotated by passes through the inside of the feed-out roll 5, the feed-out shaft 7 rotates. And the feeding case 5
A gear case 57 is provided on the side surface of the drive gear 6, and the drive gear 3 is disposed within the gear case 57. The drive gear 3 rotates together with the feed roll 5 at the rotational speed of the feed shaft 7.

When the fertilizer delivery device A is installed alone, the teeth of the drive gear 3 rotate backward in an exposed state, and when the seeding device is installed, the drive gear 4 of the seeding delivery device B meshes with the drive gear 3.
The pay-out roll 6 in the pay-out case 62 is
The delivery roll 6, which rotates in the opposite direction to the delivery roll 5, also has insertion holes 6a engraved on its circumference, and a scraping brush 34 is disposed on the outer periphery of the delivery roll 6. The drive gear 4 is disposed in a gear case 63.

Also, the gear case 5 of the feeding cases 56 and 62
Bearing cases 59, 64 are provided protrudingly on the side opposite to 7, 63, and feeding amount adjustment levers 48, 49 are disposed inside the bearing cases 59, 64. By adjusting the feeding amount adjustment levers 48 and 49, the size of the fitting hole 5a in the feeding case 56 can be changed, and the size of the fitting hole 5a can be changed.
By changing the amount, the amount of feed can be adjusted.

Furthermore, hopper shutters 40 and 39 are constructed below the fertilization hopper 1 and the seeding hopper 2, and by opening and closing the hopper shutters 40 and 39, the fertilization hopper 1 and the seeding hopper 2 are moved to the fertilization feeding device A. And when removed from the sowing and feeding device B, it can be made into a portable container.

Conventional hopper parts were fixed to the frame or feeding device part with bolts, etc., so they could not be easily attached or removed, and even if you tried to remove them by force, there was no hopper shutter at the bottom. Furthermore, it was not possible to take over the hopper from a fertilizer bag or seed bag while lowering it down and placing it in a low position.

However, in the present invention, both the fertilizing hopper 1 and the sowing hopper 2 have one-touch fittings 31 and 32 between the fertilizing and dispensing device A and the sowing dispensing device B.
This allows it to be easily removed.
Hopper shutters 40 and 39 are arranged at the bottom openings of the fertilizing hopper 1 and the seeding hopper 2 so that fertilizer and seeds can be passed on when removed and placed in a low position.
The hopper shutters 40 and 39 are open for normal fertilization and seeding work, and are closed with the bottom opening closed only when used as a portable container for replenishing the contents, etc. It is something.

Further, as shown in FIG. 5, the fertilizing feeding device A and the seeding feeding device B are made removable, and furthermore, the fertilizing feeding device A and the fertilizing hopper 1, the seeding feeding device B and the seeding hopper 2 are made removable,
Furthermore, between the fertilizing hopper 1 and the seeding hopper 2,
It is made removable.

In addition, the insertion hole of the fertilization hopper 1 on the top surface of the fertilization feeding device A and the insertion hole of the seeding hopper 2 on the top of the seeding feeding device B are configured in the same shape, so that the fertilization hopper 1 with a large capacity is replaced with the seeding hopper 2. It can be changed and used.

In addition, the seeding feeder B and the fertilizing feeder A are configured symmetrically, but in other respects they are configured in almost the same way, and when the fertilizer feeder A is removed, the seeding hopper 2 can be placed on the feeding shaft 7.
Similarly, a seeding hopper 2 is placed at the position of the fertilizing hopper 1.

In addition, the attachment and detachment between these four members is facilitated by using one pair of one-touch fittings 30, 31, 32, and 29 on the left and right sides. The one-touch mounting tools 30, 31, 32, 29 have locking tools 65, 43, 44, 4 arranged at corresponding positions, respectively.
2.

(f) Effects of the invention Since the invention is constructed as described above, it has the following effects.

First, in the past, in order to strengthen the support of the hopper, the hopper was fixed to the frame or feeding device part with bolts, etc., and the hopper alone could not be removed. Even when adding seeds, the operator had to climb onto the table and add the seeds.

On the other hand, as in the present invention, by making the hopper part removable while still containing the fertilizer and seeds, when replenishing the contents, the hopper can be lowered to the ground and then added. This made it easier for the operator to add contents.

Second, simply making the hopper removable does not make it a portable container because the bottom of the hopper is open.
In the present invention, by placing a hopper shutter at the bottom of the hopper, it is possible to prevent the contents from leaking while leaving the fertilizer and seeds inside the hopper, and the hopper can be carried as a container. This has become possible.

Thirdly, the connection between the fertilization hopper 1 and the sowing hopper 2 is made removable with one-touch fittings 29, 29, and the connection between the fertilization hopper 1 and the fertilizer feeding device A is made removable with one-touch fittings 31, 31, and the sowing hopper 2 is made removable with one-touch fittings 31, 31. Since the connection between the fertilizing hopper 1 and the sowing feeder B can be attached and detached using the one-touch fittings 32, 32, it is possible to work with only the fertilizing hopper 1, only with the sowing hopper 2, or with both attached. It became possible to do so.
