Description

[Detailed Description of the Invention] The present invention relates to a fertilization position confirmation gauge used in a fertilization rice transplanter, which has an extremely simple structure and is capable of easily and accurately confirming the fertilization position.

By the way, as shown in Figs. 1 and 2, the fertilizing rice transplanter has fertilizer tanks 2 installed on both sides of the upper part of the machine body 1, and the same number of planting rows as the device, that is, in front of the planting device 3 at the bottom of the machine body. It is equipped with the same number of furrowers 4 as the number of furrowers 4, and each of the furrowers and the feeding part 5 at the bottom of the tank is connected by a hose 6, so that the planting can be done by the furrower while the machine is running during planting work. A fertilization groove is formed on the mud surface A, and the fertilizer in the tank is supplied into the groove.
However, the position at which the fertilization groove is formed by the furrower 4, that is, the position at which the fertilization is applied, must be offset laterally at a certain interval from the seedling planting position, and if this offset is too wide, the seedling If the area is too narrow, fertilizer damage such as so-called seedling burn will occur. Therefore, as shown in FIG. However, as shown in Fig. 1, the actuator is only fixed at the top to the mounting frame 7 on the fuselage side, so conventionally, during installation, During the work, the lower part of the groove is often tilted with respect to the vertical direction or the longitudinal direction, causing the above-mentioned problems due to deviation in the amount of deviation relative to the seedling planting position.

The gauge according to the present invention was developed in view of the above-mentioned circumstances, and is installed on a seedling receiving plate with an L-shaped cross section that is installed horizontally at the rear of the planting device. By using a configuration in which the position of the lower end of the furrower is confirmed based on the notch for passing the attached claw, the structure is extremely simple, and the amount of deviation of the fertilization position relative to the seedling planting position is easily and accurately. This is so that it can be confirmed.

That is, as shown in an embodiment in FIG. 3, the gauge 20 of the present invention includes a rod-shaped base 21 having a required length, and an arm 2 with one end fixed perpendicularly to the center of the rod-shaped base 21.
2, and a rod-shaped measuring part 23 whose central part is fixed to the other end of the arm parallel to the base, and the measuring part 23 has a symmetrical shape with respect to the fixed part with the central arm part 22. A scale 24, 24 is attached to the center. Here, the thickness of the arm portion 22 is determined by the notch for each planting claw 3a to pass through in the seedling receiving plate 9, which has an L-shaped cross section and is horizontally installed along the lower side of the seedling resting platform 8 shown in FIG. The width is slightly smaller than the width of the notch 9a, and the thickness is such that it can be engaged without rattling within the notch, and in the illustrated embodiment, the standard position in the center is shown as the scale 24 in the measuring part 23. An indicator line 24a, an indicator line 24b indicating the inner minimum allowable position, and an indicator line 2 indicating the outer maximum allowable position
4c is attached.

Next, to explain how to use it, as shown in FIG. At the same time, the lateral position is determined by engaging the arm part 22 with the notch part 9a in the seedling receiving plate, and the arm part 22 hanging downward and its tip as shown in FIG. By swinging the fixed measuring part 23 forward about the base 21 and the holding part of the seedling receiving plate 9, the measuring part is brought into contact with the lower edge 4a of the groove cutter 4 from below. When observed from above in that state, as shown in FIG. 4b, one side 4b of the groove creator
The position of the lower end of is confirmed in relation to the scale 24 attached to the measuring section. In that case, the arm portion 22 of the gauge 20 is connected to the cutout portion 9 of the seedling receiving plate 9.
By being engaged with a, accurate positioning is achieved using the notch as a reference, that is, the planting position of the seedling, and the position of the lower end of the furrower 4 is indicated with respect to this reference. By doing so, the amount of deviation with respect to the fertilization position and seedling planting position can be confirmed with high accuracy. Here, Fig. 4 shows an example where the furrower is installed on the left side of the planting position with respect to the direction of movement of the machine, but the furrower is installed on the right side of the planting position. Measurement section 23 for equipment
The scale on the right is used.

FIG. 5 shows a tool for correcting the inappropriate position of the groove cutter, and the tool 30 has a rod-shaped working part 31 and a rod-like working part 31 with one end fixed perpendicularly to the center thereof. It has a T-shape with a rod-shaped operation part 32, and its usage is explained as shown in Fig. 5b.
When the groove cutter 4 is moved to the inside of the machine body (side a) as shown in FIG. is inserted from the outside of the machine body, and the action part 31 is received in the corner of the bracket, and the operating part is swung in the direction a'. Bottom outer surface 10

a from the inside, and bring the operating part 31 into contact with the inner surface 10d of the lower side of the bracket, and the operating part
By swinging in the b' direction, the upper edge of the notch 1
Using 0b as a fulcrum, the lower side of the bracket is pushed out in the direction b.

Furthermore, FIG. 6 shows another example of the method of installing fertilizer tanks in connection with the present invention. In this example, two tanks 2 having extending parts 5, 5 at both ends of the bottom are installed above the fuselage 1. By making the longitudinal direction perpendicular to the fuselage, and by shifting the positions of both tanks to the left and right, the extending portions 5, 5 at both ends of each tank can be positioned on one side of the fuselage by one wheel. 11, and the other side is located inside the other wheel 11, so that four groove makers 4...4 are installed on both the inside and outside of the left and right wheels 11, 11. If there is
While using the same tanks as the tanks 2 and 2 in the example of Figs. 1 and 2, the four hoses 6...6 connecting the total of four feeding parts 5...5 at the bottom of each tank and the groove cutters 4...4 are connected. without stepping over the wheel,
Therefore, it is possible to arrange the hoses without causing problems in the flow of fertilizer due to sudden bends, and the lengths of all the hoses can be made as equal as possible.

As described above, the gauge of the present invention has a base that is held on a seedling receiving plate installed horizontally behind the planting device of a rice transplanter, one end of which is fixed to the center of the base, and a seedling receiving plate that is placed horizontally behind the planting device of a rice transplanter. An arm that is engaged with a notch for passing the nail, and a measuring part that is fixed to the other end of the arm at the center parallel to the base and that is brought into contact with the lower edge of the groove cutter from below. Since the measurement part is configured with a scale, the deviation amount of the fertilization groove forming position relative to the seedling planting position can be confirmed easily and accurately with an extremely simple structure. This has the effect of preventing fertilizer damage, lack of fertilizer effect, etc. due to inappropriate deviation amount.
