Description

[Detailed description of the invention] [Industrial application field]

The present invention relates to a disc plow cultivation method and a disc plow device used in the cultivation method, and the present invention relates to a driven type and non-driven type disc plow cultivation method that can perform a pretreatment cut of a constant width, and its (method). This relates to a disc plow device used for.

[Conventional technology] The conventionally known disc plow plowing method and the disc plow device used in the plow plowing method are usually formed adjacent to the soil while plowing the fill soil with a disc bottom on the right side of the direction of travel. It is designed to be reversed and positioned according to the state of mind. [Problem to be solved]

There is no problem if the buried soil that is turned over by the bottom is turned around 180 degrees, but in reality, one soil is
The inversion is limited to about 120 degrees, and part of the buried soil surface, stubble, grass, compost, etc., is exposed to the surface of the soil field or buried in a relatively shallow area, which causes weeds and pests to grow, and the following. During the work, there were problems such as the machine becoming clogged with stubble, grass, compost, etc. That is, the problem is that the plowing performance is poor.

[Technical means to solve the problem]

Therefore, in order to ensure plowing by turning the buried soil, the present invention is equipped with a pre-processing device such as a disk jointer in front of the disk bottom, and the continuous cut pieces formed thereby are While placing it on the surface of uncultivated land adjacent to the soil or on the side of the heart of the land that is scheduled to be turned over,
The present invention is characterized in that the soil to be inverted is inverted into the trench, and the cut piece is positioned at the bottom of the trench.

【Example】

Hereinafter, the structure of the present invention will be explained with reference to the embodiments shown in FIGS. 1 to 4. First, in FIG. 1, reference numeral 11
indicates a device frame forming a disc plow device;
A strut 12 with a mounting seat for the top link is erected at the front end of the device frame 11, and a reinforcing stay 13 is installed between the strut 12 and the rear end of the device frame 11. A disk bottom 15 is attached to the rear end of the device frame 11 via an arm 14. Further, a cross spar 16 is attached to the front end of the device frame 11, and has a mounting seat 16a for a lower link, and further has a gauge wheel 17. In front of the disk bottom 15 in the work progress direction, a disk 21 serving as one of the pre-processing devices whose plowing reversal direction is opposite to that of the disk bottom 15 is attached to the device frame 11 via an arm 22. This disc 21 is narrower than the plowing width by the disc bottom 15.
The shallow area was tilled and the upper left corner of the platform H (to be inverted) was plowed.
(facing the direction of work progress) is designed to plow to the left. In addition, m4!23 is used in place of the disk 21, and a rolling coulter 31 is provided, and this rolling coulter 31 is supported by a crankshaft 32 on the AM frame 11 at a position closer to the cross spar 17. (Figures 2 and 5 show phantom lines) Next, the disc plow plowing method performed using the disc plow device according to the present invention will be explained. First, in Figure 4, FJ No. R is an inverted J Shows the circumference,
IFj t formed by plowing with disc bottom 15
It is flipped nearly 95-120 degrees during MM. Prior to the reversal of the right side in the traveling direction of the scheduled reversal distance ±H by the disc bottom 15, the disk 21 plows the upper left part of the buried soil H scheduled for reversal to the left, so that the cut piece r separated from the scheduled reversal period Saturday and Sunday is plowed to the left. is formed, and this cut piece is connected to the upper part of the uncultivated 1f!
Since the cut piece r is also located near the bottom of the groove, even if the top R of the reversing tank is not completely reversed nearly 180 degrees,
Stubble, grass, compost, etc. on the surface of the bottle are buried deep inside. In addition, in the above embodiment, an example was given in which a disk-type heavy body was used as the pre-processing device, but it is also possible to use a moldboard-type sphere instead of this sphere. In this case as well, the plowing direction of the moldboard is opposite to the plowing direction of the disc bottom. Furthermore, the disk bottom 15 is of an autorotating type that is not driven.
Alternatively, it may be of any type that is forcibly driven. [Effects of the Invention] As is clear from the above description, according to the present invention, when reversing the tillage of field cultivated soil, the surface treatment device creates continuous cut pieces on the uncultivated land side or the N'tfz side of the cut soil to be reversed. Ii
! Even if the cut pieces become thicker or thinner due to the unevenness of the iI field, the cut pieces will be formed continuously on the uncultivated land, which will impair the reversibility on the J layer that is reversed by tillage due to the disk bottom. As a result, the surface of the soil is filled with stubble and grass. The compost is buried deep and does not cause the generation of weeds or pests, and it is possible to eliminate causes of trouble such as clogging of the working machine with stubble, grass, compost, etc. in subsequent work.
