Description

[Detailed description of the invention] A plurality of wide and narrow floats that slide on the mud surface are attached to the lower part of the aircraft, and each float has a fertilization pipe whose tip part sinks into the soil to apply fertilizer. With soil fertilizer applicators that are installed so that their directions can be adjusted and fixed, the tip of each fertilizer tube can be applied evenly into the soil, especially when applying soil fertilizer to a specific position relative to the root position of the planted seedlings. If the seedlings are not placed at the appropriate depth and in the right and left positions relative to the float, it will not be possible to encourage the planted seedlings to grow evenly. Conventionally, a single plate-shaped gauge has been used as a positioning tool for the tip of the fertilizing pipe, and the upper side of the gauge is brought into contact with the bottom of the float, and the tip of the fertilizing pipe is aligned with the unevenness of the gauge surface to apply fertilizer. However, with such gauges, when the top of the gauge touches the bottom of the float, the width differs depending on the float, and the relative position of left and right cannot be determined by visual measurement. This is extremely inconvenient because the gauge has to be determined, and since the gauge is simply brought into contact with the float, its support is uncertain and proper gauge action cannot be obtained.

The present invention aims to improve this in view of the conventional situation, and it is possible to accurately set the tip position of the fertilizing pipe even for multiple floats of different shapes. It is an object of the present invention to provide a positioning gauge for a fertilizing pipe in a sub-soil fertilizing machine, which is characterized in that this can be done with a single gauge member.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings. 1 is a rice transplanter equipped with wheels 2, a seedling box 3 that reciprocates from side to side, and a planting rod 4 facing from the front on the delivery side. A fertilizer tank 5 is mounted above the machine frame 1, and below the machine frame 1, a wide float 6 is suspended in the center, and narrow floats 7 are suspended on the left and right sides. A pump 8 is installed below the seedling box 3. 9, 9... are fertilizing pipes having a mounting seat 10 with a mounting hole 10a and an adjustment slot 10b bored in the upper end, and the fertilizing pipe 9 is
It is attached to the bracket 11 attached to each of the floats 6, 7, 7 by a fixing bolt 12a and an adjusting bolt 12b, and the spout 9 at the tip of the fertilizing pipe 9
a can be freely adjusted and fixed in vertical movement on the sides of each float 6, 7, 7. 13 is a hose whose both ends are connected to the fertilizer tank 5 and the pump 8, respectively, and 14 is a hose whose both ends are connected to the pump 8 and the fertilizing pipes 9, 9, respectively.
... is a hose connected to the upper end of the fertilizer tank 5 so that the liquid fertilizer filled in the fertilizer tank 5 is pumped by the pump 8 through the hose to each fertilization pipe 9, and is discharged into the soil from its spout 9a. It's summery.

Reference numeral 15 denotes a gauge member, and groove-shaped locking portions 16, 16 having an appropriate clamping length are provided on the left and right sides of one side edge A of the gauge member to lock onto the ribs 6a protruding from both sides of the wide float 6. This locking part 1
6 and 16 are used by being fitted into the ribs 6a of the wide width float 6, and the gauge member 15 is configured to be able to slide only in the front and back direction of the wide width float 6 and not to swing from side to side or up and down. The gauge surface also has a hole 17 into which the tip of the fertilization pipe 9 fits,
17 are bored on the left and right, and the relative dimensions of the locking part 16 and the hole 17 are such that the tip of the fertilization pipe 9, that is, the spout 9a, is in a specific relative position with respect to the position of the roots of the planted seedlings. It is set like this. The hole 17 is
The upper part corresponds to a case where the fertilization depth is shallow, and the lower part corresponds to a case where the fertilization depth is deep. On the left and right sides of the other side edge B of the gauge member 15, there are groove-shaped locking portions 16', 1 having an appropriate clamping length to lock onto the ribs 7a protruding from both sides of the narrow width float 7.
6' is provided, and these locking parts 16', 16'
The gauge member 15 is supported by the float without play and is configured to slide only in the front-rear direction. Also, the hole 1 mentioned above is on the gauge surface.
Adjacent to holes 17' and 17, holes 17' and 17' are drilled at specific relative positions as before.

In this embodiment, the locking portion 16 or 16' of the gauge member 15 is fitted into the rib 6a or 7a protruding from the side surface of the floats 6, 7, but as shown in FIGS. 4a and 4b, Holding parts 20, 20 and 2 are provided with recesses for holding both sides of the respective floats 6 and 7 on the side edges of the gauge member 15, that is, on the A side and the B side.
1 and 21 may be provided so that the gauge member 15 can be slid in the longitudinal direction of the float.

Since the present invention is constructed in this way, when setting the fertilizing pipe 9 whose tip has been moved upward to the fertilizing position when transporting the machine, etc., the fixing bolt 12a and the adjusting bolt 12b are tightened. Loosen the tube and push down the fertilizing pipe 9. To set the position of the fertilizing pipe in the center, insert the gauge member 15 from behind the wide float 6 with the A side up, and align the tip of the fertilizing pipe 9 with the gauge surface. When aligned with hole 17 of
The front and back, top and bottom, left and right positions of a are set accurately,
In this state, bolts 12a and 12b are tightened to fix the fertilization pipe 9. In addition, to set the left and right outer fertilization pipes 9 to the fertilization position, insert the gauge member 15 from behind the narrow width float 7 with the B side upward.
As above, align the tip of the fertilization pipe 9 and tighten the bolt 1.
Tighten and fix 2a and 12b. After removing the gauge member 15 from the rear of the narrow width float 7, if the soil fertilizer applicator is placed in the field and the pump 8 is rotated, the liquid fertilizer filled in the fertilizer tank 5 will be distributed to each spout 9a, 9a. It is discharged from ... to a predetermined depth in the soil.

As mentioned above, the present invention is equipped with a plurality of wide and narrow floats that slide on the mud surface at the bottom of the aircraft, and each of the floats has a fertilizing tube whose tip part is immersed in the soil to apply fertilizer. are mounted so as to be adjustable and fixed in direction, respectively, and the tips of the fertilizing pipes relative to the float are positioned in line with the gauge surface of a gauge member separate from the fertilizer applicator, in which: is provided with a locking part that engages with the ribs on both sides of the wide-width float or a recess that holds both sides of the wide-width float, and the other side edge of the gauge member that engages with the ribs on both sides of the narrow-width float. A locking part or a concave part that holds both sides of the narrow float is provided, and the gauge member is slidable only in the direction of movement of the float, so that it can be fitted to and detached from the float when positioning the fertilization pipe. Therefore, when positioning the fertilization pipe, the gauge member is securely supported on the rib of the float by its locking part, or securely supported on the side of the float by its holding part, so the gauge surface does not swing back and forth and from side to side, and therefore the tip position of the fertilizing pipe can be set extremely accurately.A plurality of gauges corresponding to floats of different shapes are formed on each side edge of the gauge member. Because of this, it is possible to reliably achieve the desired purpose with just one gauge, which has a special effect on improving work efficiency. In addition, due to the float's molding, ribs for connecting the top and bottom are inevitably formed in the mating type.
By using this rib, and even if the float is of a type that does not have ribs, the gauge can be mounted stably and reliably by using the side of the float, making the mounting configuration of the gauge extremely simple, and making it possible to mount the gauge stably and reliably. It has practical effects such as being able to be used as is as a float.
