Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a drilling device for transplanting vegetable seedlings in agricultural work.

(Prior Art) For cultivating vegetables, a technique is adopted in which seedlings are transplanted onto ridges at predetermined intervals to grow.

In transplanting seedlings as described above, holes for transplanting are opened on the ridges at intervals set according to the type of seedlings and various other conditions, and rooted seedlings are transplanted into these holes.

Conventionally, as a method of taking the distance between the holes for transplantation on the ridge, use a string or a rod with a graduation of an appropriate length, place this on the ridge and make a hole according to each scale, and transplant. I am trying to move this one by one as I go.

(Problems to be solved by the invention) By the way, when using a string or stick with a scale as described above to make a hole for transplanting seedlings on the ridge, the string or stick placed directly on the ridge should be used. Since the seedlings will be transplanted by making a hole in the side, these strings and sticks will hinder the transplanting work of the seedlings.
It is troublesome and time-consuming to replace strings and sticks on the ridges as the transplantation progresses.

In addition, the optimum interval varies depending on the type of seedlings and other various conditions, but for this reason, it is complicated to handle and it is complicated to prepare many strings and sticks with scales. It is not preferable to provide a scale indicating a plurality of intervals on the string or the rod because the number of scales increases and it is easy to misunderstand.

Furthermore, using a graduated cord or stick to transplant individual seedlings while manually drilling holes with a transplanting trowel etc. not only is the work efficiency poor, but the size of the drilled hole is also constant. However, the transplanting conditions of each seedling are different, which also affects the uniformity of quality after growth.

The present invention has been made in view of the above-mentioned point, and by simply turning it lightly on the ridges, the holes for planting can be formed at the optimal intervals for transplanting seedlings, with holes arranged in a shape for transplanting. The purpose is to provide a device.

(Means for Solving the Problems) The gist of the present invention for achieving the above object is to provide an arm rod radially protruding from a boss portion and an appropriate width in which a long hole is formed in a central longitudinal direction. A perforated body that is attached to the wheel plate that has a variable diameter by curving the plate body that has an annular shape and has a variable end by superimposing the volume end and the end of the arm rod that protrudes from the long hole of the wheel plate and that pierces into the soil A planting hole drilling device is characterized in that a roller consisting of is rotatably supported at the tip of the handle.

(Operation) In the above-mentioned configuration, loosen the perforated body at the end of each arm rod on the wheel plate, change the wheel plate diameter, and adjust the hole body interval on the wheel plate so as to match the optimum transplantation interval of seedlings to be transplanted. To do.

In this state, hold the handle and lightly rotate the rolling wheel over the ridges to even out the unevenness of the part where the wheel rotates, and at the same time pierce the perforated body to create a hole for transplantation. It is provided.

The seedlings are transplanted into the holes for transplantation thus opened.

(Embodiment) An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a plan view of the present invention, FIG. 2 is a plan view of the same, and FIG. 3 is a perspective view showing a usage state.

In the figure, reference numeral 1 is a handle rod, and a fork portion 2 is connected to the tip thereof. Reference numeral 3 denotes a rolling wheel rotatably supported by the fork portion 2 via a support shaft 4, and the rolling wheel 3 is radially provided from a boss portion 5 into which the support shaft 4 is inserted and which is provided with an external thread 7. Rod 6
And a ring plate 8 in which a plate body having an appropriate width in which a long hole 9 is formed in the central longitudinal direction is curved in an annular shape, and both ends 8a are overlapped to have a variable diameter, and a tip of an arm rod protruding from the long hole 9. It consists of a perforated body 10 that is screwed in and attached to the ridge A so as to pierce into the soil on the ridge A. From the inside of the wheel plate 8 to the arm rod 6, a cap screw 11
Is screwed in to fix the wheel plate 8 between the perforated body 10 and the holding screw 11 in such a manner that it is securely clamped.

In addition, the female screw hole 12 of the hole forming body 10 into which the tip of the arm rod 6 is screwed
As shown in FIG. 4, it is assumed that it is formed in a relatively deep blind end hole, and that the size and shape of the piercing body 10 are adapted to the shape of the root of the seedling to be transplanted. Further, although not shown, in order to set the intervals between the perforated bodies 10 on the wheel plate 8, the overlapping portions 8a at both ends of the wheel plate 8 are graduated.

The present invention is configured as described above, and when setting the intervals of the holes for transplantation in conformity with the seedlings to be transplanted, when increasing the intervals, as shown in FIG. 5 (a), the arm rod 6 To loosen the drilling body 10 or the holding screw 11 against each arm rod 6 to shallowly screw the drilling body 10 into the arm rod 6 to increase the wheel plate diameter, when the planned wheel plate diameter ▲ ¹ ₁ ▼, Tighten the captive screw to fix it.

On the contrary, when the distance is made smaller, as shown in FIG. 5 (b), the perforated body 10 is deeply screwed into each arm rod 6 to make the wheel diameter smaller, and the intended wheel diameter ▲ ² _{2 When} it becomes ▼, fix the cap screw 11 by screwing it in.

6 and 7 show another embodiment of the present invention, in which the arm rods 6 corresponding to the overlapping portions at both ends of the wheel plate 8 are divided into other arm rods 6 at their intermediate portions 6a. Connected structure, arm rod 6
The number of is can be changed to 3 or 4 equiangular. If the planned transplantation interval cannot be obtained only by changing the diameter of the annulus, change the number of arms and rods to cope with this. It is the one.

(Effect) According to the present invention configured as described above, the following effects are obtained.

(1) Hold the handle and lightly rotate the rolling wheel on the ridges.
Since the holes for transplanting are formed at the optimum intervals for transplanting seedlings and in a size that fits the shape of the roots of the seedlings, all seedlings are transplanted under the same conditions, and there is a difference in growth conditions due to differences in transplanting conditions. There is no difference and the quality at the time of harvesting is made uniform to improve productivity.

(2) Since seedlings are transplanted into the holes for transplantation after the wheels have passed, compared to the conventional transplantation with graduated strings or sticks on the ridges, there is no obstacle and work efficiency is high. Is high.

(3) When the rolling wheels rotate on the ridges, the unevenness on the ridges is leveled by a light pressure from the wheel plate, so holes for transplantation are opened in this leveled surface, and the transplanting work is performed. Easy to do.

(4) When the rolling wheels rotate on the ridges, soil can freely enter and leave the inside of the wheel plate from the long hole of the wheel plate, so the wheel plate has uneven parts with height differences in the width direction. There is little lateral wobbling when riding over, and the turning posture of the rolling wheels is stable, resulting in good workability.
