Description

  The present invention relates to drilling during planting work of vegetables, flower buds, etc., and more specifically, when planting potted vegetables or flower seedlings, it is used for planting in a multi-sheet installed in a field or a vinyl sheet. The present invention relates to a planting drill that efficiently drills holes.

  Conventionally, the number of the seedlings to be transplanted in the planting work is the same as the number of seedlings to be transplanted, and one planting hole has been manually drilled, which has been a heavy labor. In recent years, in a field or a vinyl sheet, a multi-sheet is generally installed in order to moisturize seedlings to be planted, maintain soil temperature, prevent weeds, etc., and make a hole at a planting position. Installing a multi-sheet from a planted seedling requires a hole in the position of the seedling, which is a difficult task, so install a multi-sheet on the ground beforehand, and make a hole in the multi-sheet and the ground at the same time. The method of planting has been taken. This drilling operation uses a drilling tool and manually drills holes one by one, but the temperature in the greenhouse is high, and the drilling workability deteriorates due to the expansion of the multi-sheet due to the temperature, etc. In addition to being restricted by the working time, it takes a lot of time to collect the multi-sheet punched pieces after the work, and the drying of the fixed planting holes due to the delay of the working time has had an adverse effect on the planted seedlings.

Therefore, there has been proposed a “planting machine for seedling planting” in which a plurality of drilling bodies having a circular cross-section with a pointed tip are arranged in parallel on the lower surface side of a rod-shaped base body and pressed from above to the ground. Kaihei 11-318119). However, with this “planting machine for seedling planting”, it is necessary to hold the operation handle attached to the base by hand, press it manually against the ground of the field to make a hole, and move to the next position one after another. It was difficult to carry out continuous work, took a lot of work time, and forced heavy labor.
In order to improve such a problem, there is a “planting hole drilling machine” in which a wheel that rotates in contact with the ground is provided on the frame of the planting hole drilling machine, and a plurality of drilling rods are provided on the outer periphery of the wheel to constitute a drilling device It has been proposed (Japanese Patent Laid-Open No. 2000-316396). However, with this “planting hole drilling machine”, the hole made by the drilling rod provided on the outer periphery of the wheel cannot be adjusted freely according to the type of vegetable, and can only be adapted to certain vegetables. In some cases, there were holes larger or smaller than those suitable for seedlings to be planted on the sheet, and the work was sometimes interrupted. In addition, the planted seedlings have a problem that the heat retention is lowered and weeds grow.

  In general, the farmers who grow in the greenhouse are growing vegetables on the scale of several dozens, so the multi-sheets are tens of sheets and the number of holes for planting is tens of thousands. Yes, as mentioned above, drilling work by manpower requires harsh labor, so for the aging farmers, the problem of having to realize light labor in the planting process and efficient work that can be done in a short time is It has not been resolved yet.

When using the drilling machine for planting of the present invention, an operator stands in a field or a greenhouse, grasps the caps 14 and 14 of the handle 13 of the drilling machine 1 for planting with both hands, and holds the wheel on the soil in the field. (If it is in a field where a multi-seat is laid, place it on the multi-seat) and if you walk to push forward (the direction of travel in the figure), the wheels will rotate counterclockwise and The triangular blade breaks through the multi-sheet 40 by the weight of the wheel 20 and digs into the soil 50 to make a hole for planting. The operator simply pushes the planting hole drill 1 forward, the wheel 20 rotates, and the hole cutter 30 moves along with the multi-sheet 40 and the field soil 50 at regular intervals. You can drill holes 41 and dirt holes 51).

  FIG. 3 is an explanatory view showing the operation of the drilling cutter of the planting drilling machine of the present invention. FIG. 3A is a perspective view showing a state immediately before the punching cutter 30 bites into the multi-sheet 40 and the soil 50. An arrowhead-shaped tip of the mounting pin 32 pierces the multi-sheet 40, and the triangular blade at the tip of the punching cutter 30 hits the multi-sheet 40, and shows a state immediately before breaking through the ring. At this time, the coil spring 33 urges the pushing plate 33 in the extended state in the direction of the outer side of the wheel 20, that is, the direction in contact with the multi-sheet 40 and the soil 50.

  FIG. 3B is a perspective view showing a state where the punching cutter 30 bites into the multi-sheet 40 and the soil 50. Due to the weight of the wheel 20, the triangular blade at the tip of the punching cutter 30 breaks through the multi-sheet 40 in an annular shape and bites into the soil 50. At this time, the extrusion plate 33 hits the multi-sheet 40 and the soil 50 and slides in the wheel direction inside the cylindrical shape of the punching cutter 30. The coil spring 33 is in a contracted state, and urges the pusher plate 33 more strongly toward the outside of the wheel 20.

After the drilling cutter 30 has digged into the multi-sheet 40 and the soil 50, when the wheel is rotated forward, the multi-sheet 40 and the soil 50 have planting holes (the multi-sheet hole 41 and the soil hole 51 in FIG. 2). The perforated and perforated cutter 30 is in the state shown in FIGS.
FIG. 3C shows a perspective view of a state in which the punching cutter 30 has been removed from the multi-sheet 40 and the soil 50. When the wheel is rotated forward from the state of FIG. 3B, the punching cutter 30 comes out of the multi-sheet 40 and the soil 50, and at this time, the multi-sheet piece 42 and the soil 52 that are hollowed out are provided inside the punching cutter 30. However, since the extruded plate 33 is strongly biased to the outside by the coil spring 33, the soil 52 remaining inside the drilling cutter 30 is pushed out to the outside. Dropped on top. Note that the amount and state of the soil 52 entering the inside of the punching cutter 30 varies depending on the density and viscosity of the soil, but the figure shows an example.

FIG. 3D is a perspective view showing a state after the soil remaining inside the drilling cutter 30 is pushed out. By pushing the soil 52 remaining inside the hole punching cutter 30 to the outside, when the wheel 20 rotates forward to make a new planting hole, the hole punching cutter 30 is necessary every time because there is no soil remaining inside. You can drill a fixed planting hole of depth.
In the inside of the punching cutter 30, the multi-sheet piece 42 that has been cut out is caught by an arrowhead tip of the mounting pin 32 and remains, but since the multi-sheet piece 42 is thin, there is no hindrance to the drilling operation, and a certain number of sheets are punched. Once accumulated inside, it can be easily removed by the operator.

As explained above, according to the planting hole drill of the present invention, by simply pushing the wheel to roll forward, it is possible to continuously and reliably drill holes for planting at a predetermined interval. It is extremely effective in shortening work hours and reducing labor in farm work.
In addition, since the hole cutter can be easily replaced by screwing, it is possible to prepare and replace a hole cutter of a size suitable for a fixed planting hole of various sizes.
Further, in the above-described embodiment, the planting hole drill has a single wheel, but it is also possible to attach an axle to the frame 10 and attach a plurality of wheels thereto. If it does in this way, it will become possible to open a plurality of fixed planting holes simultaneously.
Further, the planting hole drill of the present invention is simple in structure, can be reduced in weight, and can be manufactured at low cost.
