Description

[Detailed explanation of the invention] (a) Industrial application field This invention is attached to the planting device of a rice transplanter to attach roots to the sides of the planted seedlings to improve the attachment of the seedlings. The present invention relates to a method for supporting a side-row fertilizer applicator that provides fertilizer.

(b) Prior art There have been so-called side-row fertilizer spreaders in the past, but in these cases, the groove-making device was simple, with a groove-making device slightly installed at the tip of a guide pipe protruding from the hopper or feeding section. However, on the contrary, it was only attached to the planting part side or the float side of the rice transplanter. However, if it is fixed only to the fertilizer applicator side, it will not be able to withstand the pressure of the mud and the attachment part will be destroyed.On the other hand, if it is fixed only to the rice transplanter side, the tip of the guide pipe and the groove-making device will be destroyed. There were problems such as the positional relationship between the fertilizer and the soil being shifted during use, and the fertilizer not being applied to the center of the furrow.

(C) Purpose of the invention The present invention was constructed in order to eliminate these problems, and it is designed to ensure that the upward load applied to the trenching device is supported by the trenching body, and that both the rice transplanter side and the fertilizer applicator side This structure eliminates the difference in position between the guide pipe and the groove-making device, and facilitates attachment to the planting area.

In addition, by supporting from two places, the fertilizer applicator itself is also supported by the framework structure from the trench-cutting device side, so that sufficient strength can be ensured even when a large amount of fertilizer is loaded.

(d) Structure of the invention The purpose of the present invention is as described above, and in order to achieve this purpose, the present invention provides a groove-making device installed in a side row fertilizer applicator, in which the rear of the groove-creating body is connected to the support frame of the fertilizer applicator. The rice transplanter is supported by a support pipe 22 that protrudes downward from the rice transplanter 13a, and the front part is supported by a planting support frame that supports the planting drive case of the rice transplanter.

(E) Embodiments and operations Next, embodiments of the present invention and their operations will be explained based on the attached drawings.

Figure 1 is an overall plan view of a riding-type 4-row rice transplanter equipped with a side-row fertilizer. FIG. 2 is a rear view of the side row fertilizer applicator for two rows on the left side, and FIG. 3 is a left side view of the side row fertilizer applicator for the first row on the left side of FIG. Figure 4 is a right side view of the second row fertilizer applicator. Figure 5 shows
FIG. 3 is a plan view of the first and second floats and the groove forming section.

In Fig. 1, the outline of a riding rice transplanter is shown.
4, 4 is a front wheel, 2 is a steering wheel, 1 is a seat, and 8 is a marker. The side row fertilizer applicator A of the present invention is constructed from the top to the rear of the seedling table.

In Figures 2, 3, 4, and 5, these drawings show a side row fertilizer applicator attached to the left two-row planting section of a four-row rice transplanter. 4
In the case of row planting, the two rows on the left and the two rows on the right each form one set. 14 is a hopper in which fertilizer is stored. 14
a is a hopper lid. The hopper 14 is externally fitted and fixed to the cap 34 portion of the upper roll case 35. The cap 34 and the upper roll case 35 are combined to form a bevel gear case, and the rotation of the fertilizer applicator drive shaft 32 is replaced by the vertical rotation of the roll drive shaft 37. The feed roll 39 rotates on the roll drive shaft 37, and since the roll upper cover 38 on the upper surface and the roll lower cover 40 on the lower surface are fixed to the roll case, the roll enters the through hole of the feed roll 39 from the opening of the roll upper cover 39. The structure is such that the ivy fertilizer is rotated approximately 180 degrees and dropped in a constant amount from the drop hole of the roll lower cover 40. A screw conveyor 36 extends from the lower end of the roll drive shaft 37 and projects from inside the guide pipe 10 to between the groove-forming U-shaped guides 17. Reference numeral 15 denotes a lower roll case, and a guide pipe 16 extends from the lower end of this lower roll case.

The power for the fertilizer applicator drive shafts 32, 32 is taken out by an arm 18 fixed to the crank part of the planting claw 50. The lower end of the interlocking link 19 is pivotally connected to the arm 18, and the upper end is fixed to the arm of the one-way clutch 20. Since the one-way clutch 20 is fixed on the coupling shaft 21, the coupling shaft 21 rotates intermittently with the crank movement of the planting claw 30, and drives the fertilizer application machine drive shafts 32, 32 with the pins 21a, 21b. There is.

The side row fertilizer applicator is supported by a support frame 13a fixed to the upper roll case 35, and the support frame 13a is supported by a column 13 extending from the planting drive case 31.

Further, as shown in FIG. 5, in the float of the four-row riding rice transplanter, the side float 9L is an inverted U-shaped float, and the center float 9C is a T-shaped float. The first and fourth rows are planted in the area surrounded by the inverted U-shaped floats, and the groove section of the side row fertilizer applicator is also provided inside the floats. Therefore, since no fast water flow occurs in this part, the trenching soil plate 28 is not constructed.
The second and third rows are provided in the fast-flowing area between the side floats 9L and center floats 9C, so the groove-cultivating soil plate 28 is installed outside of these rows to quickly cultivate the soil, and the flow of water can directly feed the fertilizer. It protects the water from being washed away.

First, referring to FIG. 3, to explain the first and fourth groove forming parts, an auxiliary groove forming body 25 fixedly and extendingly installed on the bottom surface of the side float 9L is provided in these parts.
Furthermore, a groove forming body 42 supported and extended from the planting support frame 43 portion continues therefrom. The groove-forming U-shaped guide 17 is fixed to this groove-forming body 42, and the groove-forming body 4 is also attached to a support pipe 22 extending downward from the support frame 13a of the side row fertilizer applicator.
2 are connected and supported via a mounting body 51.
Further, the guide pipe 16 is also supported by this support pipe 22. The groove making body 42 and the groove making U-shaped guide 17 are integrated to form a groove making device.

Next, the second and third trenching sections with the trenching soil plates are between the side floats 9L and the center floats 9C, so there is no auxiliary trenching body. Groove body 4
4 is fixed to the planting support frame 43, and the groove forming body 4
It is also fixed to the support pipe 22 with a mounting body 27 at the rear of the pipe 4. Then, a pivot shaft 30 is provided in the mounting body 27 portion to pivot the groove-making soil plate 28, and the spring 2
9, it is constantly biased downward.

In the structure as described above, the main part of the present invention is that the groove-creating bodies 42 and 44 of this groove-creating device are fixed to the planting support frame 43 that connects the planting drive case 31 at the front part, and the fertilization is carried out at the rear part. It is fixed to a support pipe 22 that protrudes downward from the support frame 13a of the machine, and the support pipe 22 also has the role of holding the tip of the guide pipe 16.

(f) Effects of the invention Since the invention is constructed as described above, the support structure of the fertilizer applicator is constituted by four frames, the support column 13, the support frame 13a, and the support pipe 22, through the groove-forming body. This provides strong support. Also, if the groove-making device is supported only from the guide pipe side, its strength will be weak, but since it is supported from the planting frame side as well, it becomes stronger, and since it is supported from both sides, the center of the guide pipe is always at the center of the groove-making device. This means that fertilizer is not applied to areas other than the furrow. In addition, the planting frame can absorb the upward force applied to the trenching device. Additionally, the groove-making device can be easily removed from the rice transplanter, and the guide pipe can be extended in a straight line, reducing clogging with fertilizer.
