Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention is mainly used for cultivating onions and relates to a device for making holes for planting seedlings in a field.

[0002]

[Problems to be solved by conventional techniques and devices]

 Traditionally, onion seedlings are planted exclusively by hand. For this reason, the work is rigorous, and the intervals between seedlings are not always exactly uniform, so there is the inconvenience that the growth conditions are not uniform.

If the planting work is completely mechanized, these inconveniences can be solved. However, since vegetables such as onions are generally grown on a small scale, they are not suitable for complete mechanization.

Therefore, the present invention aims to mechanize only the planting hole drilling operation with a very simple device so that it can be easily adopted by small-scale farmers.

[0005]

[Means for Solving the Problems]

 The present invention has a mounting portion to be mounted on a tractor, a supporting portion swingably mounted to the mounting portion, and a tip of which can be moved up and down, and a projection on the peripheral surface. A boring device for planting, which is rotatably attached to the tip, is rotated by the movement of a tractor, and has a boring roller for boring a planting hole by pressing a projection against the ground by its own weight.

The present invention also includes, in the above-mentioned device, a boring device for planting, which has a removing part attached to a supporting part, close to a side part of a protrusion of a boring roller, for removing adhered soil. To do.

[0007]

【Example】

 Hereinafter, an embodiment illustrating the present invention will be described in detail.

In the planting boring device 10 shown in FIGS. 1 and 2, the mounting portion 11 is formed by welding the pipes 13, ... To the L-shaped material 12, and the mounting holes 14, 14 formed in the L-shaped material 12. Can be attached to the rear end of the tractor 15 with a bolt.

The support portion 16 is formed of a rectangular frame, and the base portion and the tip portion are formed of pipes 17 and 18. The two support parts 16 pass one shaft rod 19 through the pipe 17 of the base part and the pipe 13 of the mounting part, and the shaft bar 19 is bolted to the pipe 13 so that the mounting part 11 swings. Installed as possible.

The perforating roller 20 has two protrusions 21, ... Arranged on its peripheral surface, and a pipe 22 at the center. The three perforating rollers 20 pass one shaft rod 23 through the pipe 22 at the center and the support portion 16 and the pipe 18 at the tip, and the collar 24 is bolted to both ends of the shaft rod 23 to support the support portion 16. It is rotatably attached to the tip.

The removing unit 25 is attached to a support rod 26 bolted to the supporting unit 16, is located close to the two protrusions 21 of the perforating roller 20, and removes the soil adhered to the peripheral surface of the roller. be able to.

Since the planting boring device 10 has the above-described configuration, it operates as follows.

When the attaching portion 11 is attached to the rear end of the tractor 15 and the field is advanced, the perforating rollers 20, ... Are grounded and rotate as the tractor 15 advances. At this time, the rollers 20 are pushed by their own weight into the projections 21 to open holes for planting, and three sets of two-row holes are formed. The soil adhering to the peripheral surfaces of the rollers 20, ... Is stripped off by the removing section 25, .. As a result, the protrusions 21 ,. Is open. When the tractor 15 moves on a road or the like, a chain or the like may be attached to the support portion 16 and the roller 20 may be lifted.

FIG. 3 shows another embodiment. This planting boring device 10 'has substantially the same structure as the device 10 described above, except that one supporting portion 16' and two boring rollers 20 'are used. Each part in this figure is represented by a reference numeral added to the reference numeral of each part in the above example, and a detailed description of the configuration of the device 10 'is omitted.

This planting boring device 10 'also operates in the same manner as in the above example, and two sets of two-row holes are formed. This device 10 'can be configured by using the supporting portion 16 and the perforating roller 20 of the above example as they are as the supporting portion 16' and the perforating roller 20 'and preparing only other components separately. .

In each of the above-mentioned embodiments, the removal parts 25 and 25 ′ are provided, but it goes without saying that this can be omitted depending on the usage conditions such as the nature of the soil.

[0017]

[Effect of device]

 As described above, the planting hole drilling device of the present invention allows the planting hole to be drilled simply by attaching it to the tractor and pulling it, and the drilling work can be performed very efficiently. Furthermore, this device has a structure that is remarkably simple and can be easily used by small-scale farmers because it passively rotates the perforating roller and presses the protrusion with its own weight to open a hole. Also, although not all planting work is mechanized, the planting work after drilling the planting holes with this equipment is such that while standing and walking, seedlings are thrown into the holes and soil is filled with feet to fill the holes. It is extremely simple and easy to use, and is very effective in practice. Of course, the holes are evenly spaced so that the seedlings can grow evenly.
