2. Description of the Related Art As a conventionally known compound tilling work machine, there is known a work machine for performing a tilling operation and a leveling operation, and a working machine configured to perform a leveling operation and a seeding operation. . Since these work machines can perform two or more works in one stroke, they can perform farm work efficiently and are useful. However, these operations are agricultural operations in general fields, and do not take into account weather conditions in Japan. In Japan, the amount of rainfall is greater than in the fields of Europe and the United States, so it is necessary to take measures to drain the fields. However, a multi-tasking machine focusing on this has not yet been proposed. Generally, in Japan, since the amount of rainfall is large, the fields are slightly humid, and the scale of farming is small and high-density agriculture is performed. Therefore, agriculture in Japan protects crops from damaging the crops,
At the same time, it is necessary to obtain an environment that does not cause continuous cropping failure, and for that purpose, it is necessary to establish a unique farming system in Japan. As a countermeasure against continuous cropping, for example, in the United States and Europe, arable land is used sideways to prevent fatigue of arable land.However, since it is necessary to provide fallow land, this is only possible in countries with large arable land. Therefore, it is extremely difficult to use arable land horizontally because of the small area of arable land, and it is necessary to use arable land vertically for the purpose of preventing continuous cropping failure.

[0003]

Due to the meteorological characteristics of Japan, it is necessary to prevent damage to continuous cropping in the field and work as a countermeasure against moisture damage. To remove water from the field, however, it is only necessary to turn the soil upside down. Is not enough, and a facility for actively discharging excess water to the outside is required. However, culverts and culverts have long been known as drainage means, and although this facility is effective, the cost of laying it is extremely high, and it takes a long time to perform the work. It could be. However, even if a culvert is laid, the upside-down work on a cultivated land, a so-called field, is an operation that must always be performed. Therefore, an object of the present invention is to provide a working machine that performs both the excavation reversal work between ridges as a drainage measure and the upside-down work, and can also perform ridge work.

[0004]

In order to achieve the above-mentioned object, the present invention provides at least a bottom plow work machine and a furrow cultivator on a work machine frame, and the ridge cultivator in the working direction. Is a work leading position, and the bottom plow work machine has a positional relationship such that the tilled soil by the bottom plow work machine is inverted at a position after excavation tillage by the furrow cultivator, and the ridge work in the working width direction. The machine is located at the rut position of the tractor, and the bottom plow working machine is located adjacent to the tractor, and the bottom plow working machine is configured to be able to form a ridge at a position adjacent to the ridge simultaneously with rupture of the ridge. Thus, two or more agricultural operations can be performed in one operation process. Also, the bottom plow working machine along the working machine frame,
It is characterized in that it is configured so that the furrow tilling work machine can move in the working width direction, and thereby, it is possible to perform tilling work, excavation work, and ridge work according to the furrow and ridge width. Further, the furrow tilling work machine is a subsoiling digger-plow work machine, whereby crushing of the tillage can be performed together with crushing of high ridges. Further, the furrow tilling work machine is a stable cultivating work machine, and thereby, the cultivation work of the intermediate portion between the bottom and the surface layer can be performed.

The upper end 61A of the beam 61 has an arm 15C similar to the beam 41 in the sub-soiling digger plow work machine 40.
Bolts. The stable cultivating machine 60 is provided with a function of excavating and plowing a position slightly deep from the surface of the field, in other words, an intermediate layer between the deep part and the surface part. Although not yet achieved, it is suitable for preventing moisture damage beforehand, or for field management of crops that extremely dislike moisture damage.

Next, the operation using the combined tillage implement according to the present invention will be described. The rear view of the working state is shown in FIGS. 7, 8 and 9, and a high ridge T is formed in the field shown in this figure, and between the high ridge T and the high ridge T, in other words, The wheel (rear wheel) W of the tractor is located in the furrow S so that the work can be moved. Then, in the furrow S, a subsoiling digger-plow working machine 40 constituting a furrow tilling work machine is located following the rear wheel W, and the excavating plate 42 of this working machine performs excavation work on the furrow S. It can be applied to. The excavated plate 42 is thrown upside down toward the bottom 21 while lifting the subsoil at a position deeper than the bottom of the high ridge T toward the surface. Accordingly, a deep excavation space K is formed in the furrow S as shown in FIGS.

Similarly, as shown in FIG. 8, together with this work, the bottom 2 of the bottom plow working machine 20 located adjacent to the sub-soiling digger-plow working machine 40
1 plows and inverts the upper layer portion from the ridge bottom portion of the high ridge T, and throws away the fatigue soil Tx existing on the surface side of the high ridge Tn toward the ridge S bottom. At this time, the fatigue soil Tx overlaps with the excavation space K, and the excavation space K is in a state of being buried back.
Are located on the surface side of the new high ridge Tn. At this time, the subsoil excavated by the sub-soiling digger-plow working machine 40 is reversed to the ridge S together with the fatigue soil Tx. In the newly formed high ridge Ta portion, the fatigue soil Tx is inside, and the fallow soil Ty which has been in a resting state becomes a surface, and the old and new soil are turned upside down to form a new high ridge Tn. . In this state, the shape of the high ridge is not yet formed, but it is formed into a high ridge shape during the subsequent crushing work. The excavation space K exists at the bottom of the new high ridge Ta, and although it is in a backfilled state, since it is excavated, the density of the soil is low, and a space with excellent water permeability and drainage is provided. Is supposed to exist.

The high ridge Ta portion formed as described above is
As shown in FIG. 9, the soil is crushed and crushed, and at the same time, a high ridge is formed. The packer 50 attached to the rear of the work machine frame 11 is used for the pressure reduction work, and the width and function of the packer 50 are selected according to the work purpose and scale. The new high ridge Ta is moved in the reversing direction by the plowing width of the bottom 21, and the ridge S is also formed at a position moved by the reversing width.

In the above description, the sub-soiling digger-plow working machine 40 is used as the furrow excavating working machine. However, as shown in FIGS. Well, in this case chisel 61
Excavates and plows an intermediate position between the bottom surface of the bottom 21 and the field surface. By selecting and using the type of the furrow excavator in accordance with the structure of the field, the drainage of the field is improved by plowing the furrow of the high ridge Ta. Of course, if the furrow excavation and tillage work is performed at a deep position, the drainage property of the field can be drained at a deeper position. This is preferably determined in relation to the moisture condition in the field.

[0019]

As is apparent from the above description, according to the combined tillage implement of the present invention, the reversal of plowing operation, that is, the so-called upside down operation can be performed together with the destruction operation of the ridges such as the high ridges. On the other hand, excavation tillage is performed, and a drainage space having a drainage effect can be formed at a position deeper than the tillage reversal position, and drainage of the field can be promoted by full plowing or partial deep plowing. In addition, since the bottom plow work machine and the furrow tilling work machine can be moved in the work width direction along the work machine frame, it is possible to perform work according to the environment of the field, such as the scale of the field and the interval between the ridge widths. . In addition, it is possible to form a groove for promoting drainage at a deep position where a high ridge was present using a sub-soiling digger plow as a furrow cultivating work machine, and thereby a new high ridge as a whole, It can promote the drainage effect below the bottom. In addition, since a stubble cultivator is used as a furrow cultivator, it is effective for crops that extremely dislike moisture damage, or for fields where the goal is to reduce moisture damage at all.
