Description

[Detailed description of the invention] [Industrial field of use] The present invention relates to cutting deep grooves in fields.

[Problems to be solved by the prior art and the invention] In the past, in fields, for example, rice fields, due to the mechanization of agricultural work in recent years, various large agricultural machines such as tractors and combine harvesters have been driven into the rice fields. The rice field is compacted due to the heavy weight of agricultural work, and this creates a hard soil part that extends to a depth of 20 to 30 cIIL from the rice field. A deep hard soil layer that cannot be tilled is formed at the bottom.

The existence of this deep hard soil layer not only prevents the roots of paddy rice from growing deep, but also culverts that are buried approximately in depth from the rice field surface. The systematic and systematic supply and capture of moisture is essential for the smooth growth of rice.

This has the aspect that a coordinated moisture subdivision such as excessive water drainage is not formed, which deteriorates the soil and inhibits the growth of rice and other crops.

[A way to resolve the problem]

The purpose of the present invention is to solve these problems, and its gist is to provide a groove-making rotor that connects a machine frame by a traveling machine body C-two coupling mechanism and cuts a slightly wide upper groove in the machine frame. A groove-cutting rotor for cutting a narrow lower groove is provided at the rear in the direction of movement of the groove-cutting rotor, and the groove-cutting rotor is configured to cut the lower groove in the deep hard soil layer of the field. This field deep groove cutting machine is characterized by:

[Effect]

When the traveling machine travels, the groove cutting rotor cuts a slightly wide upper groove in the field, and then the groove cutting rotor cuts a narrow lower groove in the deep hard soil layer of the field.

〔Example〕

1 to 5 show preferred embodiments of the present invention, (1
) is a traveling machine body which is a tractor, and a machine frame (3) is connected to a three-point link type coupling mechanism (2) at the rear thereof.

This connection mechanism (2) I: has lower links (4) on both left and right sides of the lower part of the traveling body (1), upper links (5) in the middle, and swing arms (6) on both left and right sides of the upper part. , a lifting link (force) that connects the middle of the swinging arm (6) and the lower link (4), and the machine frame is (3), and allows the machine frame (3) to move up and down by four swing movements of the swing arm (6) using hydraulic pressure.

A gear case (8) is attached to this machine frame (3).
The input shaft (9) and the power output shaft r10) of the tractor are connected by a flexible joint CLI).

In addition, a groove-making rotor uz is installed horizontally on the lower front side frame of the machine frame (3), and the groove-making rotor (L is the rotor shaft (end), rotor body I, and a naginata-shaped groove-making blade (I$) The rotor shaft (13 is the chain a from the front shaft housing Q of the gear case (8)
The groove making blades (LSIs) are rotated via
Delete.

The depth of the upper furrow end of this field 11 is approximately 15 cm, which is the plowing depth of the tractor.

In addition, four support rods (21J) are vertically installed in the rear part 1 of the machine frame (3), and a groove cutting rotor 3υ is installed horizontally at the bottom of each support rod (2I), and the groove cutting rotor C!υ is It consists of a rotor shaft (4), a rotor body (C), and a pair of naginata-shaped groove cutting blades (04). The lower groove (5) is cut with each pair of groove cutting blades Q4).

The depth of this lower trench end is approximately 1, which is the thickness of the deep hard soil layer (c).
It is 5cm. (3υ is the intermediate axis.

Further, the width of the upper groove end in this embodiment is approximately 50 mm, and the width of the lower groove end is approximately 50 mm.
The width of @ is approximately 15 lines.

Since the present embodiment has the above-mentioned configuration, when the traveling body (1) travels, the groove-making rotor t14 cuts the upper groove α line, and the groove-cutting rotor Qυ cuts the lower groove end.

At this time, the groove cutting rotor (La is the plowing depth of the tractor), and the upper m fit (27) is cut in ω, and the groove cutting rotor U
n is by excavating a lower groove (5) in the deep hard soil layer (c) at the bottom, so that the lower groove (5) tears the deep hard soil layer (2),
The end of the subsoil layer below the deep hard soil layer (C) is communicated with the cultivated soil layer C29), allowing so-called deep plowing work.

Therefore, the adverse effects caused by the presence of deep hard soil layers can be suppressed.

In addition, since the wide upper groove ual is cut, the grooving rotor Cυ can be placed as low as possible, and the grooving rotor Qυ
The groove cutting blade (foundation) can be shortened in length and the cutting depth is short, so even in hard deep soil layers (28,1), the groove cutting rotor can be used.
The cutting resistance of υ can be reduced.

Note that the shape, quantity, etc. of the groove cutting blade α4 and the groove cutting blade Q fathom are not limited to those in the example, and the groove cutting rotor 4 groove cutting rotor α-
The support structure is designed with appropriate changes.

〔Effect of the invention〕

As described above, in the present invention, the slightly wide upper groove is cut by the groove cutting rotor, and the narrow lower groove is cut by the groove cutting rotor, so it is possible to easily cut grooves in deep hard soil layers. The harmful effects of deep hard soil layers can be suppressed and work efficiency can be improved.

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