Description

Detailed Description of the Invention (a) Industrial Application Field The present invention is attached to a rice transplanter, and uses a planting claw to perform two stages of lateral fertilization and deep fertilization in the vicinity of the later planted seedlings a. This relates to a deep and shallow two-stage fertilizer applicator that applies fertilizer to areas.

(B) Prior Art Conventionally, tiered fertilization devices have been known that are attached to rice transplanters and perform side-row fertilization.

(c) Problems to be solved by the invention However, the fertilizer sprayed by the side row fertilization device is an immediate-acting fertilizer to improve the survival of the seedlings. It was necessary to separately spray a slow-release fertilizer to improve root expansion.

The present invention enables both side-row fertilization and deep-layer fertilization to be carried out at the same time as planting, in order to save the effort of spreading slow-release fertilizer after conventional planting.

In such a deep and shallow two-stage fertilizer applicator, the amount of immediate-release fertilizer applied in the side rows and the amount of slow-release fertilizer applied in deep layers vary depending on the region and season, so the amount of both fertilizers can be adjusted to The side row fertilization and the deep furrowing body 4 can be easily adjusted separately or in proportion to each other using the link or arm portion exposed to the outside.

(d) Means for solving the problem The object of the present invention is as described above. Next, the structure for achieving the object will be explained.

In order to perform two stages of fertilization, lateral fertilization and deep fertilization, near the planted seedlings, a lateral fertilization feeder and a deep fertilizer feeder B were placed side by side, and both feeders were installed in the M section of the planting mission case. In the configuration in which the crank arm 18 is intermittently driven, the feed amount of the side-row fertilization feed-out device A and the feed amount of the deep fertilization feed-out device B can be adjusted separately at the drive portion from the crank arm 18 to the drive shaft of each feed-out device. This is what I did.

The side row fertilizer dropping lower to which the side row guide pipe 20 is connected is fixed to the side row cropping groove body 3, and the side row cropping groove body 3 is attached to the side of the float 13 as shown in FIG. As if
Two sets are placed on the sides.

Further, the deep fertilization section constituted by the deep fertilization tank 2, the deep fertilization delivery device B, and the guide pipe 21 is fixed to the planting mission case M by a support rod 19.

The lower end of the deep guide pipe 21 is fixed to the deep fertilizer drop port 8 , and the deep fertilizer drop port 8 is fixed to the deep groove cutting body 4 , and the deep groove cutting body 4 is connected to the central rear end of the float 13 . to 1
It is assembled and installed.

However, as shown in FIG. 7, in the case of 6 rows, the deep trenching body 4c attached to the rear of the central center flow l□ 13c allows the center flow 1-130 to automatically adjust the planting depth. Because of this, it is necessary to be able to move up and down freely, so they are separated and supported independently.

In addition, the trench is created using the deep trencher 4, but since the trench cannot be created deep enough, the rice transplanter is placed directly behind the left and right rear wheels 33L and 33R of the rice transplanter. The left and right deep trenches 4s and 4s are arranged so as to be located.

Moreover, since the rear wheel 33 is not located in the front part of the central deep groove-making body 4C, the groove-making disk 9 protrudes downward from the elevating link 12, and grooves are formed by the groove-making disk 9. .

Thereby, the load on the deep trenching body 4 can be reduced.

The drive system of the deep fertilization dispensing device B to the lateral fertilization dispensing device configured as described above is the main part of the present invention, and both the lateral fertilization dispensing device A and the deep fertilization dispensing device B are installed in the planting mission case M. The dispensing amount can be adjusted separately or proportionally and at the same time.

In the embodiment shown in FIG. 3, a metering device configured separately for lateral fertilization and deep fertilization will be explained.

A crank arm 18 protrudes from the planting mission case M, and the crank arm 18 continuously rotates, but the crank link 15 pivotally connected thereto only makes reciprocating motion.

A counter bell crank 14 is pivotally supported at the upper end of the crank link 15.
At part 4, the deep fertilization dispensing device B is transferred to the side row fertilization dispensing device.

By opening a large number of holes 4a and changing the pivotal connection between the crank links 15 and 17, the rotation angle of the feeding shaft is changed.

In this embodiment as well, lateral fertilization and deep fertilization can only be adjusted separately.

Next, explanation will be given with reference to the embodiment shown in FIG.

In this configuration, the crank link 15 from the crank arm 18 is a single piece, and the mechanism up to driving the side strip feed-out shaft arm 23 is the same as that in FIG. 3. By adjusting the rotation of the side-row metering arm 26 using the fixing bolt 26a, the amount of the side-row fertilization system WA can be adjusted.

Furthermore, a deep metering arm 22 is provided on the side strip feed-out shaft 34,
A large number of metering holes 22a are provided in the deep metering arm 22,
Adjustment is possible by changing the connecting portion of the link 17.

Also, instead of the deep metering arm 22, the deep feed shaft arm 2
4 may be provided with a metering hole 24a.

In FIG. 5, side strip fertilization and deep layer fertilization can be proportionately adjusted by rotating the side strip metering arm 26 for metering.

FIG. 8 shows the driving part of the planting claw 6 and the driving part of the clanfer l, 18. The planting claw 6 is configured as a rotary planting claw, and can be opened and closed at both ends of the rotating case 11. It is composed of

In FIG. 9 and FIG. 10, the configuration of the side-row fertilization feeding device A is disclosed.

The lateral fertilization dispensing device A can also be used as the same device as the deep fertilizing dispensing device B, and even if the rotation direction of the lateral fertilization shaft 34 changes, the tip of the lateral fertilization dispensing shaft 34 can be moved so that the dispensing disk 46 can be - The bevel gear that meshes with the bell gear 35 is meshed with 36 and 37 from above and below.

Although the hevel gears 36 and 37 rotate in opposite directions, one-way clutches 38 and 39 that rotate in the same direction are interposed between each of them and the clutch cylinder shaft 47.

With this configuration, when the reciprocating rotation of the side strip feed-out shaft arm 23 and the deep layer feed-out shaft arm 24 is made into intermittent rotation in the position direction by another one-way clutch provided on the side strip feed-out shaft 34, the intermittent rotation direction Regardless of which side is the disc axis 4
0 can be intermittently rotated in the same set rotational direction.

Therefore, with the side row fertilization delivery device and the deep fertilization delivery device B,
Even if the mounting direction is changed or the drive direction is reversed, a common feeding device can be used.

A clutch shifter 43 is interposed between the clutch cylinder shaft 47 and the disk shaft 40 loosely fitted therein, and by operating the clutch shifter 43, the clutch cylinder shaft 47 is shifted. Transmission of rotation to the disk shaft 40 can be disconnected or disconnected.

Also, a clogging prevention spring 45 is installed inside the disc shaft 40.
