DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in a fertilizer and a float mounting support mechanism of a fertilizer transplanter which performs planting work simultaneously with fertilization.

[0002]

2. Description of the Related Art Conventionally, a fertilizer of a fertilizer transplanter that performs planting work simultaneously with fertilizer application is integrally attached to a float that slides the planting device on the ground, and is planted at the rear of the planting device. A fertilizer or the like in the form of a paste is applied to the side of the seedling planted by the planting body that moves in a streak-like or spot-seeding manner. The float is attached to the planting section machine frame, that is, the planter case, so as to slide up and down along the unevenness of the field scene.

[0003]

In an apparatus in which a fertilizer application nozzle is directly mounted on the float in a vertically adjustable manner,
The planting depth is adjusted above and below the float, and the fertilization depth is adjusted by moving the nozzle up and down with respect to the float. Looking at the relationship between the planting depth adjustment and the fertilization depth adjustment in this planting device, the planting depth changes in conjunction with the up and down of the float, so the fertilization depth is adjusted by adjusting the nozzle for the float. It becomes constant at the determined position.

Further, in the case of a device in which a fertilizer application nozzle is attached to a planter case (planter machine frame), the planting depth is adjusted by moving the float up and down, and the fertilizer application depth is adjusted by moving the nozzle up and down with respect to the machine frame. It is what you do. Looking at the relationship between the planting depth adjustment and the fertilization depth adjustment in this device, the vertical position of the fertilizing nozzle is not linked to the vertical direction of the float. Therefore, when the planting depth is reduced, the fertilization depth is also reduced, and there is a possibility that the fertilizer will flow out of the surface layer. Further, when the planting depth is changed, it is necessary to adjust the fertilization depth, and there is a problem that workability is poor.

[0005] In addition, the fertilizer usually receives considerably large soil resistance. In such a case, the float is tilted forward and downward to push the soil forward or hinder smooth running. There is a drawback that the fertilization planting operation cannot be performed, and there is a problem particularly in the former known example.

[0006]

Means for Solving the Problems The present invention solves the above-mentioned problems of the conventional apparatus, and A) fertilizes fertilizer into soil in a planting apparatus with a float mounted on a traveling body. In a fertilizer transfer machine that is equipped with a fertilizer and has a fertilizer mounting base located between the planting transmission case and the float and attached to the planting section machine frame side,
The funnel can be tilted up and down with respect to the fertilizer mounting base.
Provide a fertilizer transplanter that can be carried .

[0007] B) with a float against fertilization tool mounting base for supporting tiltably vertically, fertilization tool mounting base
Is moved up and down with respect to the planting transmission case.
Provided is a fertilizer transfer machine whose depth is adjustable .

[0008]

[Operation] Since the fertilizer application mounting base 7 is supported by the planting section machine frame 40 (that is, the planter case), the space between the planting section machine frame 40 and the float 5 can be effectively used.
Further, since the fertilizer 6 is supported via the fertilizer mounting base 7 supported below the planting section machine frame 40, the fertilizer 6 is miniaturized, and soil is removed by the fertilizer 6 during traveling. The fertilizer 6 can be fertilized at a predetermined position without any deformation of the fertilizer 6 even if the applied resistance acts, and a fertilizer transfer machine excellent in durability can be provided. Further, the float can be easily moved up and down by adjusting the mounting base 7 up and down, so that the planting depth can be easily adjusted.

The float 5 (FIG. 5, center float 5) mounted as described above is provided with an operating piece 55 at its tip, and the operating piece 55 and the planting depth installed on the traveling machine 1 side. The planting depth is used as a sensing float for control of the control device by being connected to a control device (not shown) via a linking device such as a link or a rod. That is, the float 5 is provided with a fertilizer 6 (6
0, 61), the planting section machine frame 4 separate from the float 5
It is independently mounted on the 0 side, that is, on the mounting base 7.

Therefore, even when the fertilizer 6 receives a large soil resistance during traveling, the float 5 is not affected by the resistance of the float 5, so that the float 5 can slide well in the field scene. As a result, it is possible to accurately detect the unevenness of the ground and to automatically control a good planting depth. In addition, the fertilizer 6 (60, 61) itself is float 5
Since it is supported independently of (5, 5a), there is a feature that the fertilizer application at a predetermined depth can be favorably performed without being affected by the forward / backward tilt of the float 5.

The bottom surface 70 of the mounting base 7 (FIG. 4)
D) is such that the front and rear bottom surfaces 70 are inclined upward with the lower end of the mounting hole 7a for supporting the float 5 in a side view.
The shape is inverted. By forming the bottom surface 70 in this manner, it is possible to sufficiently secure the operation amount of the float 5 that is tilted and rotated up and down around the mounting hole 7a. The bottom surface 70 acts as a stopper for the float 5 so that the float 5 is inclined more than necessary along the unevenness of the ground to prevent the muddy soil from being pushed forward and the like. Can be.

The maximum tilt restricting means of the float 5 is performed by contacting the upper surface of the float 5 with the bottom surface of the mounting base 7 at the front and rear ends thereof. (FIG. 2). The adjusting support rod 72 constitutes one link of the four-bar link mechanism, and the assembling adjustment of the above-described link mechanism for attaching the mounting base 7 to the planting section machine frame 40 is easily and appropriately performed. Can be done.

When simultaneous fertilization and planting are performed by using the above-mentioned apparatus, a) the cultivated field is immersed in the field with shallow watering. B) By operating each operation lever, the rotor 3 and the planting device 4
The lower part of the rotor 3 penetrates shallowly into the rice field while driving
The machine is run with the floats 5, 5a lowered so that they touch the ground.

(C) Then, the rotor 3 scrapes the surface layer of the plowed soil, but the lower layer is left as a plowed aggregate structure, and the planted body 4c of the planting device 4 is removed.
Is scraped one by one from the lower end of the mat-shaped seedling in the seedling mounting table 41 and planted in the field where the surface layer has been scraped. At this time,
The two-stage fertilizers 60 and 61 are supported by the support adjustment mechanism 65,
With the respective fertilization depths set by operating 65a (FIG. 3), the operating lever 78 (FIG. 2) is operated to lock the lever guide 79 at that position.

In this state, as shown in FIG. 2, the mounting base 7 is positioned and fixed at a desired position with respect to the planting section machine frame 40 via a supporting rod 71 and an adjusting supporting rod 72 constituting a link mechanism. Is done. Float 5,5a in this way
The planting depth of the fertilizers 60 and 61 can be easily changed and adjusted by operating the mounting base 7 up and down.
, That is, the fertilization depth can always be set to the set fertilization depth regardless of the adjustment of the planting depth, and two-stage fertilization with different depths can be favorably performed in parallel with the planting operation.

Even if the fertilizers 60 and 61 projecting downward receive excessive soil resistance as the machine body 1 travels, the mounting base 7 and the like separately formed independently of the fertilizers 60 and 61 are provided. The float 5 attached to the planting section machine frame 40 (planter case) via the mounting section made of is not affected. Therefore, unlike the conventional device, the planting work can be smoothly performed along the ground without leveling forward and without obstruction such as pushing forward of the soil, and a good planting operation can be performed while leveling the field scene. It can be performed.

As a result, even when the center float 5 is used as a sensing float for controlling the planting depth, good control of the planting depth can be achieved. In the above-described embodiment, the present invention has been described with respect to the simultaneous transplanting machine equipped with the rotor 3. However, the present invention is not limited to this, and a normal transplanting machine without the rotor 3 may be used. Is fertilizer 6
It is not limited to the two-stage fertilization system provided with 0 and 61, but may be a one-stage fertilization system.

Further, although the shape of the fertilizer 6 is shown as a pipe for fertilizing a paste-like fertilizer, the shape of the fertilizer can be changed arbitrarily when fertilizing a granular fertilizer or the like. .
