Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a disc plow cultivation method and apparatus for reversing tillage while making pretreatment cuts with a constant width.

[Prior Art] In order to dry wet rice fields, plowing is performed by digging up the soil while turning it in the same direction. Furthermore, various plow devices used for this work have been proposed.

A typical bottom plow device uses the bottom to dig up soil in the same direction, and excavates soil that has been formed next to the soil by previous plowing.
Invert into groove. The inverted soil will dry out as its surface comes into contact with the atmosphere. Also, when organic matter is plowed in during inversion, soil fertility is restored.

[Problems to be solved by the invention] When the soil plowed by the bottom is turned over nearly 180 degrees, the original purpose, such as drying wet fields, is achieved. However, in actual tillage inversion using a disc bottom, the soil inversion stops at around 95 to 120 degrees, and part of the soil surface, stumps, soil, compost, etc., remains exposed on the field surface. , or even if it is buried, it will be buried relatively shallowly.

Incomplete tillage reversal can lead to the emergence of weeds, pests, etc. In addition, stumps, grass, compost, etc. become entangled with the working equipment that performs the subsequent work, making it impossible to continue the work smoothly. That is, plowing performance deteriorates.

The present invention was devised to solve such problems, and by forming cut pieces on the soil in the untilled area prior to reversing tillage, the present invention can be applied to the surface of the soil that has been inverted. The purpose is to bury certain stumps, weeds, compost, etc. deep.

[Means for Solving the Problems] In order to achieve the objective, the disc plow cultivation method of the present invention partially separates the surface layer of the soil adjacent to the uncultivated area with a preceding sub-plow, A cut piece is formed that is connected to the uncultivated area, and the cut pieces are hanging down to the furrow side from the previous tillage reversal. Features.

In addition, the disc plow device has a disc bottom that is tilted in the direction of work progress so as to plow and invert the soil scheduled for inversion toward the furrow side, and a surface layer of the soil that is scheduled to be inverted adjacent to the uncultivated area. The present invention is characterized in that it is equipped with a sub-plow that plows in the direction of the starting point, and that the sub-plow is attached to the machine frame at a position forward of the disc bottom in the direction of work progress.

[Examples] Hereinafter, the present invention will be specifically described by way of examples with reference to the drawings.

As shown in FIG. 1, the disc plow apparatus of this embodiment has a strut 12 provided with a top link mounting seat erected at the front end of a body frame 11. Further, the cross bar 16 is attached to the front end of the fuselage frame 11, and is shown in FIGS.
As shown in the figure, a lower link mounting seat 16a is provided.

Between the strut 12 and the fuselage frame 11,
A reinforcing stay 13 is installed. On the other hand, a disk bottom 15 is attached to the rear end of the body frame 11 via an arm 14. The disc bottom 15 may be either a rotating type that rotates as the disc plow device travels or a driven type that rotates by power transmitted from an appropriate power source.

A pretreatment disk 21 is attached to the body frame 11 via an arm 22 at a position in front of the disk bottom 15 with respect to the work progress direction. The pretreatment disk 21 is inclined with respect to the work progress direction so that the plowing reversal direction is opposite to the disk bottom 15.

The pretreatment disk 21 plows a shallower area that is narrower than the plowing width of the disk bottom 15, and plows the upper left corner of the soil H, which is to be turned over, to the left in the direction of work progress. Note that instead of the pretreatment disk 21, a pre-plough or the like that performs similar tillage may be used. Further, in order to adjust the plowing depth by the disc bottom 15, it is preferable to attach a gauge wheel to an appropriate location on the fuselage frame 11.

Furthermore, it is also possible to use a rolling coulter 31 supported by the fuselage frame 11 via a crankshaft 32 at a position forward of the crossbar 16, as shown by imaginary lines in FIGS. 2 and 5, for example. It is. As the rolling coulter 31, a disk-shaped rotary blade is used that makes vertical cuts in the soil H to be turned over and the untilled area K in order to facilitate reversal of tillage.

Next, plowing work using this disc plow device will be explained.

Prior to reversing tillage using disc bottom 15,
As shown in FIG. 4, plowing is reversed using the pretreatment disk 21. That is, pretreatment disk 2
According to 1, the top left of soil H is to be plowed to the left. As a result, a cut piece r separated from the soil H to be inverted is formed. The cut piece r is
It is connected to the upper part of uncultivated area K.

Then, the subsequent disk bottom 15 advances to the soil H, which is scheduled to be turned over, where cut pieces r have been formed by the previous plowing. Reversal schedule: The soil H is plowed and reversed by the disc bottom 15, and is then reversed into the groove M formed by the previous plowing.

At this time, the cut piece r hangs down from the side N of the soil H that is to be inverted. Plan to turn around in this state〓
Since the soil H is tilled inverted, it is planned to be inverted. The surface layer of the soil H is pulled by the cut piece r, and the cut piece r is
It is fed to the bottom of the groove M. As a result, the inversion
As shown as soil R, stumps, weeds, compost, etc. in the surface layer are buried deep.

In this way, the disc bottom 15
Even if the plowing is not reversed by nearly 180 degrees, the surface layer of the soil H will be pumped into the depths of the soil H, which is scheduled to be reversed by being pulled by the cut piece r. Therefore, after reversal of tillage,
Stumps, weeds, compost, etc. are no longer located on the top of the soil R, and subsequent work can be carried out smoothly.

In the above embodiment, the cut piece r is to be inverted.
The case where 1 is used has been explained. However, the present invention is not limited to this, and as long as the surface layer of the soil H is partially tilled in the opposite direction to the tilling direction of the disk bottom 15, a mold can be used instead of the pretreatment disk 21. It is also possible to use a type of plow.

[Effects of the Invention] As explained above, in the present invention, by plowing the surface layer of the soil to be inverted adjacent to the uncultivated area with a sub-plow, the soil to be inverted is separated from the soil and is not yet plowed. A cut piece is formed that is connected to the plowed area, and the cut piece is hanging down on the furrow side from the previous plowing.The soil is being plowed and turned over at the disc bottom. Therefore, during tillage reversal, the surface layer of the soil is pulled by the cut pieces, and the surface layer of the soil containing stumps, weeds, compost, etc. is pushed deeper. As a result, even if tillage reversal due to disk bottom
Even if the tillage is not done nearly 180 degrees, after the soil has been turned over, the tillage reversal work is carried out with no stumps, weeds, compost, etc. on the top of the soil. Therefore, problems such as the growth of weeds and pathogenic bacteria are suppressed in plowed fields, and subsequent working equipment can operate smoothly.
