Description

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

[Problems to be solved by conventional technology and invention]

Traditionally, for example, in rice fields, 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, and the large weight of these various farm machines compacts the river surface, which causes the rice fields to collapse. A hard soil layer is formed at a depth of 20 to 30 r, and since the EJF depth is about 10 to 15 cr by a tractor, a hard soil layer that cannot be dug is formed below the cultivated soil layer. ing.

The existence of this hard soil layer not only prevents the roots of paddy rice from growing deep, but also causes the irrigation and drainage functions to fail, even though the culvert is buried approximately 1x below the circular surface. The planned and systematic water supply, capture, and excess water drainage, which are essential for the smooth growth of rice, are not able to be coordinated, 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,
Vertical holes of approximately 20 to 60 crtt in depth and diameters of approximately 3 cx that penetrate the hard soil layer are drilled over almost the entire field in accordance with the arrangement of the emerging plants. Focusing on the fact that holes can improve the irrigation and drainage functions, we devised a field drilling device that can automatically drill such vertical holes in a scattered manner as the tractor travels.

8, and both rotating shafts 18 are connected to sprockets 19.20,
The rotation can be transmitted by the chain 21, and the power can be transmitted from the power take-off shaft 22 of the crawler-type traveling body l to the front rotating shaft 18 via the universal joint 23, the intermediate shaft 24, and the gears 25 and 26. One rotating arm 27 is installed at both ends.
A slide roller 28 is provided at the tip of the rotating arm 27, and a slide hole 29 extending in the front-rear direction is formed in the elevating member 13, and the slide roller 28 is engaged with the slide hole 29. This is how I did it.

Reference numeral 30 denotes a perforated body, in which a machine-shaped engagement part 31 is formed in the lifting part +413, a longitudinally moving part ke 32 is engaged with the engaging part 31 so as to be movable back and forth by a roller 33, and the longitudinally moving member 3
2 and the elevating member 13 are provided with a spring portion VI35 that urges the back-and-forth moving member 32 by gravity and abuts the stopper strike 34, and a perforated body 30 is provided vertically on the back-and-forth moving member 32.

This perforated body 30 is formed to have a concave planar cross section, and a perforated piece 37 forming a hollowed hole portion 36 is formed at the lower end thereof.
A plate-shaped reinforcing rib 38 is provided on the surface thereof.

Further, in this embodiment, a fertilizer tank 39 is disposed in the upper part of the main body member 12, and a discharge mechanism 4 is provided in the lower part of the main body member 12.
The discharge mechanism 40 includes a case 41, a plunger 42, and a return spring 43, connects the fertilizer tank 39 and the perforated body 30 with a discharge vibrator 44 via the discharge mechanism 40, and has an elevating member. 13 is formed with a pressing piece 45, and the plunger 42 of the discharge mechanism 40 is pressed down by the pressing piece 45 at the lowering limit of the elevating member 13, so that fertilizer can be discharged from the lower end of the perforation body 30 via the discharge vibrator 44. I have to.

46 is a support wheel.

Further, the number of perforated bodies 30 is not limited to two as in this embodiment, but may be four, eight, ten, etc.

In this case, care should be taken to ensure that the perforating body 30 is penetrated into the soil as sequentially as possible, and the reaction to the penetration toward the main body member 12 is minimized.

Further, it is desirable that the arrangement pitch of the perforated bodies 30, that is, the pitch of the vertical holes a, be matched to the distance between plants as much as possible, for example, approximately 25 to 30 cm, and the perforation depth is 20 cm.
~60cm, and the perforation diameter is approximately 30jIjI.

Since this embodiment has the above-mentioned configuration, when the power take-off shaft 22 of the track type traveling body l is rotated, the intermediate shaft 24 is rotated via the universal joint 23, and therefore the front and rear rotating shafts 18 are also rotated.
Due to this rotation, the rotating arm 27 rotates, and the rotating arm 2
7 slide roller 28 and the slide hole 2 of the elevating member 13
9 and the guide groove 15 and the guide roller 14, the elevating member 13 is moved up and down, whereby the two perforating bodies 30 alternately penetrate into the soil. The top of the field is hollowed out in a columnar shape using the hollowed-out hole part 36 of the perforation piece 37, the hollowed-out soil is captured and lifted by adhesion, and the hollowed-out soil at this position is pushed up and discharged by the next drilling at another position, As a result, it can be perforated.

At this time, when the perforating body 30 is penetrating into the soil, the perforating body 30 must maintain its penetrating stopped state even if the track type traveling vehicle l moves forward, so at this time, the roller 3
3, the back-and-forth moving member 32 slides relatively backward so that the boring body 30 can be stopped at its insertion position, and when the boring body 30 comes out of the soil, it is returned to its original backside position by the spring member 35. By repeating this process, smooth drilling is performed. Therefore, just by moving the crawler-type traveling vehicle l forward, it is possible to drill vertical holes a in a scattered manner over substantially the entire field.

Further, the perforated body 30 penetrates into the soil, and the pressing piece 45 presses the plunger 42 at the lowered position, whereby the fertilizer in the fertilizer tank 39 is discharged from the lower end of the perforated body 30. Fertilization can be applied deep.

Although the main body member 12 is attached to the rear part in this embodiment, the present invention can also be applied to the front part or side part of the crawler-type traveling vehicle l.

In addition, powdered fertilizer and liquid fertilizer are used as fertilizer.

Further, if the discharge mechanism 40 is a weight drop type, it can be a simple on-off valve type, or it can be a type that uses a cylinder to pour out fertilizer at a predetermined pressure.

〔Effect of the invention〕

As described above, the present invention can perforate a field using the vertical movement mechanism simply by driving the crawler-type traveling machine,
The presence of the vertical holes improves water permeability and air permeability in the deep parts, which allows roots to grow and spread deep, improving field soil, which in turn improves crop growth.
It is expected that the yield will improve.

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