Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a field drilling device for a tractor.

[Conventional technology]

Traditionally, in rice fields, for example, due to the mechanization of agricultural work in recent years, various large agricultural machines such as tractors and combines have been driven into the rice fields. A sandy area with a depth of 20 to 30 cm was formed,
Since the plowing depth by the tractor is approximately 10 to 15 degrees, a hard soil layer that cannot be tilled is formed below the cultivated soil layer.

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 approximately one level below the rice field. Planned and systematic water supply and capture is essential for the smooth growth of rice.

Cooperative water regulation such as excessive water drainage is not possible, which deteriorates the soil and inhibits the growth of paddy rice.

Therefore, in order to eliminate the adverse effects caused by the existence of the hard soil layer,
Drilling a vertical hole in the rice field with a hole diameter of about 3 cIIL and a depth of about 30 to 60 inches that penetrates the hard soil layer, noting that the irrigation and drainage functions can be improved by the vertical hole,
Therefore, various field drilling devices have been devised that can automatically drill holes by the traveling motion of the vertical hole tractor.

[Problem that the invention seeks to solve]

However, in certain fields, the vertical holes alone may not be sufficient.

[Means for solving problems]

The gist of the present invention is to connect a machine frame to a tractor by a coupling mechanism, arrange a perforation mechanism on the machine frame, vertically install an elevating body on the machine frame so that it can be raised and lowered, and attach the perforating body to the elevating body. the vertical hole is drilled in the field soil by the piercing/extraction operation of the boring body, wherein the lifting body is repeatedly moved up and down by the drilling mechanism, and a vertical hole is bored in the field soil by the piercing/extraction operation of the boring body, a position forward in the advancing direction of the drilling position by the boring body; It is constructed by disposing wheels and an equivalent treading member.

[For production]

While traveling on the tractor, the lifting body is moved up and down repeatedly by the perforating mechanism, and with this movement, the perforating body descends and penetrates into the field soil, and then
As a result, vertical holes are scattered in the field soil, and on the other hand, treading members such as wheels and paddles located in front of the perforation position in the direction of travel press the perforation position and create grooves at the perforation position. A groove is formed so that a vertical hole is drilled within the groove.

In addition, the perforated body 0υ of this example is formed with a concave cross section, has a cylindrical perforation piece (42+) at the lower end, and has a reinforcing lip (43) on the front surface. When the hole is pulled out, the hole in the soil is captured and lifted up by the hole drill (0), and as a result, the hole is drilled through the soil. The diameter of the vertical hole (a) is preferably about 3 cIrL.

Further, in this embodiment, a treading member, which is a wheel, is attached to the lower part of the lift guide frame (3) and at the front position in the traveling direction of the left and rightmost perforated bodies (4υ).

In addition, in this embodiment, six elevating bodies (c) are provided so as to be able to be raised and lowered repeatedly as described above, and the elevating bodies (c) are arranged at one time each other.
It is designed to move up and down repeatedly with a phase shift of 80 degrees, so that drilling is performed alternately and as much as possible.
This is intended to alleviate the reaction force associated with this.

Also, the arrangement pitch of the perforated body (41), that is, the vertical hole (a
) is desirably matched to the distance between the plants as much as possible, and for example, about 25 to 30 fi is appropriate.

Since the first embodiment has the above configuration, when the power take-up shaft α1 is rotated while the tractor (1) is running, the power transmission joint (

The elevating body (C) alternately moves up and down with the connecting rod α1) and the guide roller Qω (C), thereby lifting the perforated body (41
) alternately penetrate into the soil, capture the mud at the time of drilling, lift the hollowed-out mud, and discharge the hollowed-out soil while drilling at another position, thus driving the tractor (1). This allows drilling work in the field.

In this gap, even if the tractor (1) moves forward, the drilling body (41) must maintain its drilling stopped state when drilling into the soil. ) allows the boring body 0υ to stop at the drilling position, and when the boring body (41) comes out of the soil, the return spring (40
), it slides back to its original front position, and this process is repeated to perform smooth drilling. Therefore, just by moving the tractor (1) forward, the vertical holes (a) can be scattered over almost the entire field. perforated.

On the other hand, the treading member (goods) is the perforated body (
41) in the forward direction of the traveling direction of the perforation position, in this case, an arc-shaped concave groove (49) is continuously formed, and as a result, the perforated body G1 of the leftmost cloth is formed in the concave groove (4 (g)). is perforated,
A longitudinal hole (a) is drilled into the groove.

As shown in Figure 3, this four-row groove (by the phrase, a collection and drainage action of field water occurs, and the field water flowing into the groove is fed to the vertical hole Ca).
), it penetrates underground well, allowing the field to dry out better, and as a result, the drainage effect is further improved.

After the drilling work is completed, when the swing arm (5) of the tractor (1) is pulled up and swung, the pull-up link (6)
The lower link (4) swings upward, and the lifting guide frame (3) rises.
As the fulcrum shaft α of the lever mechanism 00) rises, the fulcrum shaft α of the lever mechanism 00) also rises, and one end of the swing lever αυ is connected to the connecting pin (16i) of the machine frame (8) by the chain (13), so that the swing lever The housing υ swings around its -man end part, and the other end, that is, the tip of the swinging lever aυ, is the distance between the -man end part and the fulcrum shaft 2), -the man end part and the other end. As a result, the amount of swing of the swing arm (5) is increased by the lever mechanism Cl0), and the machine frame (8) is raised by the swing lever Cf1). The machine frame (8) rises together with the lifting guide frame (3) and rises significantly due to the action of the swinging lever αD, and when the work is finished or when not in use, the machine frame (8) is reliably pulled up from the soil. can be placed.

Note that the mounting position of the machine frame (8) is the tractor (
1), but it can also be applied to the front or side of the tractor (1), and the mechanism for moving the perforator (4) back and forth is not limited to this embodiment.

In addition, in the case of this embodiment, the treading members (b) are placed only in the front position of the perforated body (4υ) on both sides of the leftmost fabric, but the treading members (b) are placed in the front position of all the perforated bodies (41). It can also be applied by arranging it at a position in front of any one of the perforated bodies (4). Also, as the treading member (goods), a rack, a roller, etc. can be applied.

〔Effect of the invention〕

As described above, the present invention is constructed by disposing a treading member such as a wheel or a paddle at a position in front of the drilling position of the drilling body in the traveling direction. The operation lowers the drilling body into the soil, and then removes it and raises it, allowing drilling work to be performed in the open soil.At this time, the treading member presses the position in front of the drilling position, creating a depression. The grooves are formed continuously, and as a result, vertical holes are drilled in the grooves, and the grooves function to collect and drain field water, allowing the water in the grooves to permeate underground through the vertical holes. This allows for good drainage, which is essential for growth.
Cooperative water regulation such as systematic water supply, capture, and excess water drainage can be effectively achieved.

As described above, the intended purpose can be fully achieved.
