Description

[Detailed Description of the Invention] [Industrial field of application] This invention relates to a bottom plow device for burial of long-sized plants,
More specifically, the present invention relates to a bottom plow device capable of completely burying a root-growing long plant in the ground.

[Conventional technology]

A so-called two-step tillage bottom plow device in which a deep plowing bottom is arranged in front of the work advancing direction and a shallow plowing bottom is arranged rearward is conventionally known, and the gravel soil is inverted to the right with respect to the work advancing direction. In the bottom plow device, a deep plowing bottom is arranged on the right side in the work advancing direction, a shallow plowing bottom is arranged in parallel on the left side, and the deep plowing bottom is seen from the side,
There is a shallow tillage bottom, and the shallow tillage bottom reverses tillage about the upper half of the planned inversion depth, and the inverted soil is put into the gravel groove formed by the front deep tillage bottom. In the next step, the lower half left by the deep plowing bottom is tilled, and it is inverted on the gravel soil that was inverted by the shallow plowing bottom in the previous step.

The plowing action using such a two-step tillage bottom plow device will be described in more detail with reference to FIGS. 4 and 5.

First, as shown in FIG. 4, the relationship between the plowing cross section in the previous working stroke and the passing position of the tractor T and the plow in this working stroke is shown. uneverted gravel soil B ₄ to be caused tillage is inverted on gravel soil a ₄₁ being already reversed, the previously inverted gravel soil B _41. Furthermore, the unreversed gravel A ₅ cultivated by the shallow tillage bottom 2 is
It is turned upside down into the gravel groove formed by the process of the deep plowing bottom 1 to become the already-inverted gravel A ₅₁ . In addition, in FIG. 4, A _{1 to} A ₄ indicate unreversed upper gravel, B _{1 to} B ₄ indicate lower unreversed gravel, and inverted gravel is unreversed. Gravel soil A ₁ has already been turned over Gravel soil A ₁₁ has not been turned over Gravel soil B
It is indicated by a two-digit subscript so that ₁ is already inverted B soil B ₁₁ .

In this case, the uninverted gravel A ₅ is slit by the coulter 3 in the uncultivated land portion as shown in FIG. 5 to facilitate the inversion by the shallow tillage bottom 2.

[Problems to be solved by the device]

In the two-step tillage bottom plow device as described above, weeds grown on cultivated soil by inverted gravel and grain culms after harvest are scraped to prevent regrowth, and by ripening in soil, it is regenerated as organic fertilizer. It is intended to be used and is effective and beneficial in terms of soil fertility, but as shown in Fig. 5, it is a shallow uninverted gravel soil A with slits in the wall by disc coulter 3. _{When 5} is turned upside down with a shallow tillage bottom, the large plant S is leaning against the side of the adjacent inverted soil B ₄₁ , and the tip of the long plant is seen from the boundary of the soil line and is buried. In spite of having made it, there was a case where he was revived again. this is,
This tendency is particularly noticeable when the root-rooting large plants are overgrown on the cultivated soil, and in such a case, it was buried between the inverted gravel and the inverted gravel in the adjacent row. The long plant that should have been growing continues to grow by looking above the ground, and again, the useless long plant grows on the cultivated soil, making it impossible to plant the crop or hindering the growth of the planted plant. , There was a problem that affected the harvest of crops.

Therefore, an object of the present invention is to provide a bottom plow device capable of reliably burying an inverted gravel even in a tall plant having a large height.

[Means for Solving the Problems] In order to achieve the above-mentioned object, the present invention has a deep plowing bottom formed in parallel with a deep plowing bottom and a shallow plowing bottom arranged in parallel in the forward direction. In a bottom plow device configured to throw gravel soil that is inverted by a shallow tillage bottom into a gravel ditch, in front of the shallow tillage bottom's sheer point and at the shallow tillage bottom's tillage point in the work advancing direction forward of the above shallow tillage bottom. The first and second disc coulters are provided at the center in the width direction, and the deep plowing bottom is arranged approximately one plunge away from the rear wheel of the tractor on the gravel soil reversal side, so that it is inverted by the shallow plowing bottom in the preceding stroke. It became possible to invert the gravel soil cultivated by a deep plowing bottom while treading on a large plant that looked into the ground from the gravel soil with the tractor rear wheel on the gravel inversion side. It is characterized by that.

[Action]

According to the present invention as described above, the gravel soil cultivated in the shallow tillage bottom is provided by providing the first and second disc coulters at the front of the sheer point in the shallow tillage bottom and the center in the tillage width direction, respectively. It is divided into two at the center and inverted, and the cultivated soil surface on which the large plants grow is completely turned upside down and put into the deep gravel groove formed by the deep plowing bottom in front. Since the deep plowing bottom is arranged approximately one plowing width away from the rear wheel of the tractor on the gravel soil reversal side, the deep plowing bottom introduced into the deep gravel groove formed by the deep plowing bottom in the next stroke You can work while pressing the tip of the long plant that has been peeked above the ground from the inverted gravel with the rear wheel of the tractor on the gravel inversion side. It can be stepped on and placed on top of it so that it can be covered with inverted gravel by a deep plowing bottom.

〔Example〕

An embodiment in which the present invention is applied to a reversible bottom plow device will be described below with reference to FIGS.
In these drawings, reference numeral 10 indicates the bottom plow device as a whole, and a deep plowing bottom 12 and a shallow plowing bottom 13 are provided above and below the frame 11.
And a first coulter 14 and a second coulter 15 for shallow tillage bottom 13 are provided in front of the shallow tillage bottom 13 in the work advancing direction. The first coulter 14 is in front of the sheer point of the shallow plowing bottom 13, and the second coulter 14 is
Reference numeral 15 is the center of the shallow plowing bottom in the plowing width direction, in other words, it is arranged in front of the first coulter 14 in a side view at a position where the plowing width is divided into two. The levels of both the first and second coulters 14 and 15 are set so that a slit can be formed to a position slightly deeper than the plowing depth of the shallow plowing bottom 13, and from the sheer point of the shallow plowing bottom to the rear. The roots of perennial macrophytes do not become blocked. Also, deep plowing bottom
12 It is placed about one plough apart from the tractor rear wheel (not shown) on the gravel soil reversal side (right side in Fig. 3).

Next, a plowing operation using the bottom plow device for burying a long plant according to the present invention will be described.

First, as shown in FIG. 2 and FIG. 3, the deep plowing bottom 12 is located with respect to the shallow gravel groove formed in the previous work step (see FIG. 3), and the cultivated land adjacent to the shallow gravel groove is formed. The first and second coulters 14 and 15 for shallow plowing have slits, and the unreversed gravel R ₁ and R ₂ that have been divided are deep pits formed after the shallow plowing bottom 13 has passed through the deep plowing bottom 12. Fly into K ₁ and invert to form shallow pits K ₂ . Then, the already-inverted gravel R ₃₁ and R ₃₂ inverted by the shallow tillage bottom 13 is the already-inverted gravel R ₃₁ placed on the already-inverted gravel R ₃₂ , and is a long-sized plant generated on the cultivated soil. S is turned upside down and is buried between the existing inverted gravels R ₂₂ and R ₂₁ , which are adjacent to the stems, and the already inverted gravels R ₂₃ previously cultivated at the deep plowing bottom 12 in this process.

In addition, in this work step, the already-reversed gravel R ₂₃ from the deep plowing bottom 12 is placed on the already-reversed gravel R ₂₂ and R ₂₁ that were reversed in the previous work step. The work is carried out so that the rear wheel T of the tractor on the side treads on the tip of the long plant seen from the already reversed gravel R ₂₂ , R ₂₁ to the ground. With this, by adding the pedaling pressure of the rear wheel T of the tractor onto the already-reversed gravel R ₂₂ and R ₂₁ before the already-reversed gravel R ₂₃ being reversed, the other side of the already-reversed gravel R ₂₂ and R _{21 on} the opposite side is added. Squeeze the stalks that are peeking from the side to suppress it, and on top of that, turn over the existing gravel R
_{Since 23} is inverted and placed, the long plant S can be completely buried in the ground and the regeneration of the long plant can be surely suppressed.

[Effect of device]
