Description

[Detailed description of the invention] The invention relates to a field drilling device.

Traditionally, in rice fields, for example, due to the mechanization of agricultural work in recent years, various large-scale agricultural workers 1 such as tractors and combine harvesters have been driven into the rice fields. A hard soil layer with a depth of 20 to 30 m is formed, and the plowing depth with a tractor is approximately 10 to 15 m, so a hard soil layer that cannot be plowed is formed at the bottom of the plowed soil layer. has been done.

The existence of this hard soil layer not only inhibits the roots of paddy rice from growing deep down, but also causes the irrigation and drainage functions to fail, even though culverts are buried at a depth of about 1 nL below the rice field surface. The systematic and systematic water supply, capture, and drainage of excess water, which are essential for the smooth growth of rice, are not possible, which deteriorates the soil and impedes the growth of paddy rice.

Therefore, in order to eliminate the adverse effects caused by the existence of the hard soil layer,
A vertical hole with a hole diameter of about 3G and a depth of about 30 to 60σ that penetrates the hard soil pigeon is drilled on the river surface, and the vertical hole allows the above-mentioned irrigation.
Recognizing that the drainage function can be improved, various field drilling devices have been devised that can automatically drill the vertical holes by the running motion of a tractor.

By the way, as this type of perforated body, one in which the main body of the perforated body is formed of a round bar or a square bar, and the lower end thereof is formed with a sharp point is used.

However, this drilling device attempts to drill a vertical hole by pushing the soil surrounding the hole aside by piercing the soil, so when the soil is hard soil, the size of the hole diameter is limited. Since it is a perforated body, there is a disadvantage that the large puncture force at the time of penetration may cause puncture failure or bending of the perforated body due to buckling.

Incidentally, the diameter of the arJ earth-piercing device (9) is approximately 3 CIK.

Further, in this embodiment, the support vehicle and the rear bipedal wheel shaft of the machine frame (3) are respectively removably installed vertically at the lower part of the lifting guide frame (C).

In addition, in this embodiment, six elevating bodies (2) are provided so as to be able to move up and down repeatedly as described in Nil, and the elevating bodies (B) are designed to move up and down repeatedly with a phase shift of 180 degrees. Therefore, the perforations are performed alternately to reduce the reaction force caused by the perforation as much as possible.

In addition, the arrangement pitch of the perforated body (5), that is, the vertical hole (a)
It is desirable to adjust the pitch to the size of the forest area as much as possible, and a suitable pitch is, for example, about 25 to 30 Cff1.

Since this embodiment has the above configuration, when the power take-off shaft (27) is rotated while the tractor (1) is traveling, the transmission joint (
The crankshaft (36) rotates via the gear case (c), telescopic joint O1), power shaft (support)), and tine 61, and the rotation of this crankshaft (g) causes the crank (4 (
II, connecting rod u] J, i idle roller C321 (33
), the elevating body (goods) is moved up and down alternately, whereby the perforating body (5) alternately penetrates into the soil, captures the muddy soil at the time of drilling, lifts the hollowed muddy soil, and lifts it at another position. By drilling, the hollowed out soil is removed and the tractor (1
) is run to perform drilling work in the field.

In addition, even if the tractor (1) moves forward, the drilling body (5) must maintain its drilling stopped state when drilling into the soil. ) allows the boring body (5) to stop at the drilling position, and when the boring body +5J comes out of the soil, ζ2 is released by the return spring 147.
1 slides back to the original front position and repeats this to perform smooth drilling. Therefore, just by moving the tractor (1) forward, the vertical holes (a) can be drilled over the entire area of the rice field in a scattered state ζ2. At this time, since an upper opening (9) is formed in the lower part of the perforating body (5) than the perforating piece (8), when the perforating body (5) is penetrated into the soil, The upper passage (9) is narrowed and the soil flows through the upper passage (9) while being compressed. Therefore, the soil is shaped like a long column (2 holes are cut out, separating the surrounding soil from the soil inside the upper passage (9)). C2. The soil in the upper opening (9) will be compacted and will loosen after passing through the upper opening (9), and when the perforation body (5) is lifted and removed, the upper Doorway (
9) The compacted soil in the hole acts as a lifting base plate for the hollowed out soil above it (two holes), and the hollowed out and divided internal peripheral wall acts as an upward guide, and for both purposes (
2. Therefore, when drilling, the soil that has been hollowed out is lifted up and taken out, and once it comes out of the soil, the loose soil is easily discharged and fallen away from the surface of the drilling body [51]. In addition, during the next drilling operation, the mud in the main body (as shown in June 2nd) will be lifted up and separated by the mud at that position, and the upper opening (9), which acted as the lifting bottom plate, will be removed. The soil is lifted up, and new soil is formed in the upper opening (9) that acts as a lifting bottom plate, and in this way, drilling operations are performed one after another (=).

Moreover, the main body (6) of the perforator (5) is formed of a long narrow plate material, and the lower end thereof is shaped like a sharp point (sword-shaped), so that the resistance to penetration into the field soil is minimized. In addition, the reinforcing member aQ receives penetration resistance and resistance accompanying running, and breakage of the perforated body (5) can be prevented accordingly.

After the drilling work is completed, when the swinging arm 0 of the tractor (1) is pulled up and swung, the lower link υ swings upward due to the lifting link (131), and the lifting guide frame αω rises due to this ζ2. As the lifting guide (15) rises, the fulcrum shaft of the lever mechanism (L7) also rises, and the end of the swinging lever (18) is connected to the connecting pin (A) of the machine frame (3) by a chain (A). c); Since the two swing levers (181) are connected, the two swing levers (181 swing as the center of the "manendo" part, and the other end, that is, the tip end of the swing lever 181, is the "manende" center). and the fulcrum shaft (L), and the lever ratio of the distance between the one end and the other end, and thereby the amount of swinging of the swinging arms a is equal to the lever al M (17 ) l
2, the machine frame <31 is raised by the swing lever α barrel, and the machine frame (3) rises together with the lifting guide frame (151), and is greatly raised by the action of the swing lever a8, and the machine frame (3) is raised by the action of the swing lever a8. When finished and not in use, the perforated body (5) can be reliably pulled up from the soil.

Note that the mounting position of the machine frame (3) is the tractor (
Although it is connected to the rear part of the tractor (1), it can also be applied to the front or side part of the tractor (1), and the mechanism for moving the perforated body (5) back and forth is not limited to this embodiment. As mentioned above, the main body (6) of the perforated body (5) is formed of a long narrow plate material, the lower end of the perforated body (5) is formed into a sharp point (7), and the perforated body ( A substantially U-shaped perforation piece (8) is formed on one side of the lower part of 5), and the perforation piece (8) and the main body part (6)
A device opening (9) is formed with (2) the main body part (2).
Since the reinforcing member QOI extending vertically is formed protrudingly on the other side of the tractor (1), the drilling mechanism (
5), the drilling body (5) is lowered into the soil, and then removed.Thus, drilling work in the field soil can be performed, and as a result, the vertical hole (a) is formed. At this time, since a device port (9) is formed in the lower part of the drilling body (5) through the piercing piece (8) & two, the soil will not pass through the device port (9) when drilling into the soil. 9) to pass through the soil while being compressed, thereby hollowing out the soil in the form of a long column. The soil in the device opening (9) will be compacted and will loosen once it passes through the device opening (9), and when lifting and extracting the perforated body (5), the soil in the device opening (9) will be The compacted soil acts as a bottom plate to lift the hollowed out soil above, and the hollowed and divided inner circumferential wall acts as an upward guide. The hollowed out soil will be lifted up and taken out, and if it comes out of the soil, the loose soil will easily fall away from the surface of the perforated body (5), and the main body During the next drilling operation, the layered mud in (6) is lifted and separated by the mud at that position, and the soil in the device opening (9), which acted as the lifting bottom plate, is lifted up, and , soil is formed in the device opening (9) to serve as a new lifting bottom plate, and in this way, nine holes can be worked in sequence with high efficiency.

Therefore, the soil can be taken out well by the perforator (5), and the dirt floor from the perforator (5) becomes good, so the drilling can be performed continuously in a good condition without reducing the perforation ability. Further, the main body (6) of the perforator (5) is formed of a long narrow plate material, and the lower end thereof is formed into a sharp point (7). Because of this, the penetration resistance into the field soil is minimized, and the reinforcing member QOI receives the penetration resistance and the resistance associated with running, thereby making it possible to prevent breakage of the perforated body (5).

The above intended objectives will be fully achieved.
