There is a technology that eliminates the problem described above.
It is a structure to provide a leveling plate.
It is not possible to connect the excavated plate, leveling plate and auxiliary leveling plate
Easy to form a buried structure that can be installed and detached integrally
It is not possible to easily reduce the size and simplification of the soil cultivation structure.
At the same time, the shoulder of the ridge and the upper part of the ridge by connecting the excavated plate and the level plate
Problems such as difficulty in improving the tailoring function of the surface
is there.

[0004]

According to the present invention, a flattened flat plate for leveling the upper surface of the ridge is provided continuously at the tip of the excavator plate of the cultivator, at the tip of the excavator plate of the cultivator. The auxiliary leveling plate used appropriately for wide ridges is extended to the leveling plate so that it can be stored, and the leveling plate is rotatably connected to the excavating plate via a hinge.
And tie the spring to the excavated plate and the flat plate via a spring rod.
It is installed so that the pressure can be adjusted freely, and when making narrow ridges with narrow ridge widths, the auxiliary flat plate is stored compactly so that it does not become an obstacle during work, and on the other hand, when making wide ridges, the auxiliary flat plate is laid horizontally In the direction of the ridges, the leveling plate and the auxiliary leveling plate can be used to lay and cultivate the ridges appropriately in accordance with the wide ridges, and always properly handle various ridges regardless of the width of the ridges between the ridges. It can make a constant ridge and can be connected rotatably.
Since an adjustable spring is provided between the excavated plate and the leveling plate,
An equalizing plate and an auxiliary equalizing plate are connected to the excavated plate and
The cultivation structure to be removed can be easily formed and the cultivation structure can be downsized.
And simplification, etc.
Therefore, the ridge can be made by sliding on the ridge at a constant pressure.
Of the shoulder and upper surface of the ridge by connecting
Improvement can be easily achieved .

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 is an explanatory plan view of the cultivator, and FIG. 2 is an overall side view of the management machine. In the figure, (1) is an engine frame on which an engine (2) is mounted, and (3) is a rear end of the frame (1). A traveling transmission case which is integrally connected to input an engine output via a transmission case (4); (5) a traveling iron wheel which is supported at a lower portion of the transmission case (3) via an axle (6); 7) is a cultivator mounted on the rear frame (8) of the transmission case (3), (9) is a tail wheel for adjusting the depth of the cultivator (7), and (10) is horizontal to the handle base (11). A steering handle rotatably supporting the base end, which is constructed so that soil is gathered to the right and left sides by a cultivator (7) pulled by the body during traveling to form a furrow.

As shown in FIGS. 3 and 4, the cultivator (7) has a mounting rod (12) erected at a front portion of a rear frame (8) supported by a support height adjusting bolt (8a). It can be mounted freely, and the left and right sides of the central blade (13)
4) (14) is provided, and a flattened flat plate (15) (15) for leveling the ridge top surface at the tip of the excavated plate (14) (14)
Are continuously provided along the shape of the excavating plates (14) and (14), and bolts (1) are attached to the excavating plates (14) and (14).
6) and a flat plate (15) (15) through the slot (17)
Are connected and supported in a freely adjustable manner, and the leveling plate (1
5) An auxiliary leveling plate (19) (19) is rotatably extended at the outer end of (15) via a hinge (18) so that the width of the ridge surface is narrow within the width of the leveling plate (15). When making the ridge, the auxiliary flat plate (19) is folded and stored on the upper surface of the flat plate (15), and the work is performed. On the other hand, when the ridge surface width is longer than the flat plate (15), the auxiliary flat plate (19) is flattened. The flat ridges (15) and (15) are extended by approximately 180 degrees so that the auxiliary flat plate (19) is in a state of being slid substantially horizontally on the upper surface of the ridge free (own weight) so as to form a wide ridge. Make up.

In this embodiment, the auxiliary flat plate (19) is formed as a flat plate (19) when a narrow ridge having a narrow ridge width can be formed by using only the flat plate (15). 15) The cultivator (7), which is folded and stored on the upper side and does not disturb the flat plate (19), has an excellent handling operation by a compact cultivator (7) having a small left and right width. On the other hand, when making a wide ridge with a large ridge width where the ridge making is not sufficient with only the flat plate (15), the auxiliary flat plate (19) is expanded to about 180 degrees outside the flat plate (15). The two flat plates (15) and (19) are used to make a good ridge making the upper surface of the ridge even.

FIG. 5 shows a configuration in which a leveling plate (15) is connected to the excavating plate (14) so as to be rotatable and the ground pressure can be adjusted, and a hinge (20) is attached to the tip of the excavating plate (14). ), The leveling plate (15) is rotatably connected to the excavating plate (14) and the pivoting plate (21) fixed to the leveling plate (15).
(22) The compression spring (2) is interposed between the compression springs (2) via the spring rods (23).
4) is arranged so that the spring pressure can be freely adjusted, and the flat plate (15) is slid against the upper surface of the ridge with a constant spring pressure to form the ridge.

As is clear from the above, the cultivator (7)
At the tip of the excavated plate (14), level the top to level the top of the ridge.
Auxiliary plate (15) is connected and used appropriately when wide ridges are used.
The leveling plate (19) is extended to the leveling plate (15) so as to be freely stored.
And at the same time through the hinge (20) to the excavated plate (14)

When the auxiliary flat plate (19) is stored compactly when working
When making wide ridges without wide obstacles
The auxiliary leveling plate (19) is expanded in the horizontal direction to the leveling plate (1).
5) and the auxiliary flat plate (19) are suitable for this wide ridge.
Ridge work and cultivation work can be performed.
Regardless of the ridge, it is always fixed to correspond to various ridges
The earthenware plate (1
An adjustable spring (24) is provided between 4) and the leveling plate (15).
Flat plate (15) and auxiliary flat plate on the excavated plate (14)
(19) is connected to form a buried structure that can be attached and detached integrally
To reduce and simplify the soil cultivation structure
The flat plate (15) is slid on the ridge with a constant pressure by the spring (24).
The ridges can be made by contacting them, and the excavated plate (14)
Improvement of tailoring function of ridge shoulder and ridge upper surface by connection of 5)
And so on.

[Effects of the Invention] As is apparent from the above embodiments, in the present invention, a flattened flat plate (15) for leveling the ridge upper surface is continuously provided at the tip of the excavated plate (14) of the cultivator (7). The auxiliary leveling plate (19), which is appropriately used at the time of wide ridge , is extended to the leveling plate ( 15) so as to be stowable, and the butterfly is mounted on the excavating plate (14).
The leveling plate (15) is rotatably connected via a number (20).
The spring rod (2) is placed on the excavated plate (14) and the leveling plate (15).
The spring (24) is attached via 3) so that the spring pressure can be adjusted. The auxiliary flat plate (19) is compactly stored when a narrow ridge is made, so that it is an obstacle during operation. Without
On the other hand, when making a wide ridge with a wide ridge, the auxiliary leveling plate (19) is expanded in the horizontal direction, and the leveling plate (15) and the auxiliary leveling plate (19) are laid and cultivated so as to appropriately correspond to the wide ridge. the can, along with the always it is possible to perform the constant ridge-making so as to correspond to the rather diverse ridge related to the wide and narrow of the furrow by furrow Article, times
