The operation was difficult due to the large size. In addition, since the rotor is linked to the top and bottom of the shallow device, the shoulder dropping plate also goes down when plowing deeply, so that the adjustment is doubled and the work is troublesome. Furthermore, as for the molded plate, it was a type that was fixed according to the shape of the ridge,
If the control machine swings right and left while the machine is in progress, there is a problem that the soil lifted by the formed plate is hooked off, and the resistance of the hooked soil causes the machine body to lose its balance and the work finish to be uneven. Therefore, the present invention solves the above-mentioned problem by mounting a shoulder dropping plate interlocking with the vertical movement of the deep and shallow equipment, and a molded plate capable of constantly preventing scattering and soil holding in accordance with the working conditions in the tillage device. Solve.

[0004]

The above is the problem to be solved by the present invention. Next, means for solving the problem will be described. That is, in the management machine equipped with the tilling device, a shoulder dropping plate was attached to the middle part of the tail wheel supporting rod which moves up and down by the depth adjusting device so that the position can be adjusted right and left according to the width of the ridge shoulder.

[0005] In a management machine equipped with a tilling device, a forming plate is mounted on the rear surface of a rotary cover that slides left and right and up and down.

The molded plate is made of a flexible material.

The shoulder dropping plates 8 are slightly narrower at the front side and slightly wider at the rear side so that they do not penetrate. The size of the tail wheel 7 should be approximately 30 cm upward from the vicinity of the center of the tail wheel 7 because the purpose is to make the tail wheel easier to perform.

Next, the configuration of the formed plate 9 will be described with reference to FIG. The formed plate 9 is provided with a rear wall 24 of the rotary cover 24.
The molded plate 9 is composed of a soil molding part 91 and a press molding part 92. The press forming portion 92 is disposed below the rear wall 24d of the rotary cover 24 and has a rectangular shape that is long in the up-down direction. The mulch forming portion 91 is located above the press forming portion 92, and the press forming is performed. The rectangular shape is wider than the portion 92 in the left-right direction. Then, the mulch forming section 91 and the press forming section 92
Are integrally mounted on the rear wall 24d. The forming plate 9 also slides in accordance with the sliding of the sliding portion 24c and the rear wall 24d in the left, right, up and down directions. At the front end of the rotary cover 24, a scattering prevention plate is arranged.

In this embodiment, the molded plate 9 is made of a flexible rubber material. Thereby, the molded plate 9 is configured to be easily mounted according to the shape of the mounting place such as the rotary cover 24. Further, the molding plate 9 can be made of a flexible synthetic resin member.

With the above configuration, when the management machine of the present invention carries out the work of unloading the green onion cultivation site, first, as shown in FIG. 8
With this, the raised surface of the ridge is cut off near the vertical. As a result, the corners of the shoulders of the ridge shown by arrow A are shaved, and the side surfaces of the ridges are gently inclined upward. It is hard to collapse and stable work can be performed. further,
Since the shoulder drop plate 8 is attached to the tail wheel support rod 71,
This is linked with the vertical adjustment of the tail wheel 7. As a result,
The work of vertically adjusting the tail wheel 7 and the work of vertically adjusting the shoulder dropping plate 8 that have been performed separately are unified, and the adjustment work can be reduced.

The width between the shoulder dropping plates 8 can be easily adjusted by loosening the bolt 84, and the width in the left-right direction can be freely adjusted according to the width of the ridge. is there. Further, with the simple configuration as described above, the shoulder dropping plate 8 can be compactly stored in the rotary cover 24. Further, the shoulder drop plate 8 is
Since it is located behind the tail wheel 7 in the traveling direction, the reaction reaction force to the handle portion due to the contact between the shoulder dropping plate 8 and the ridge shoulder becomes smaller and the operability is improved as compared with the case where the tail wheel 7 is arranged in front of the conventional body. Therefore, stable running is possible.

Then, after the shoulder of the ridge is scraped off by the shoulder dropper 8, the lower soil is plowed by the tilling nail, and the soil is scraped upward by the rotation drive of the tilling nail. The soil that has been lifted upward is guided outward in the rotary cover 24 and lifts the soil plowed on the ridges on both sides of the rotary covers 24. At this time, the forming plate 9 mounted on the rear side surface of the rotary cover 24 prevents the tilling claw from scattering the scraped-up soil to the rear, and also presses the ridge. Fig. 5
As shown in FIG.
(In the vicinity), and at the same time,
1 ensures that the soil is brought to the root of the crop (in the vicinity of arrow D in the figure). As a result, the slope of the ridge gently shaved by the shoulder dropping plate 8 described above is sufficiently suppressed, and the formation of the ridge is ensured. In addition, the ability to sufficiently fill the root of the crop plays an important role in growing the crop.

Further, since the forming plate 9 is integrally mounted on the rotary cover 24 which slides left and right and up and down, even if the position of the rotary cover 24 is changed, the effect of always preventing scattering and holding the earth can be obtained. Molding is possible.

[0021]

As described above, the present invention has the following advantages. In other words, a shoulder drop mounting stay was arranged on the tail wheel arm that goes up and down in the shallow device, and the shoulder drop plate was attached to the left and right according to the width of the ridge shoulder, so the vertical adjustment of the tail wheel and the vertical adjustment of the shoulder drop plate were performed. It is possible to arrange the shoulder dropper at an appropriate position in combination with the vertical adjustment of the tail wheel without performing separately. In addition, the width adjustment in the left-right direction can be easily performed by loosening the bolt, and the adjustment work can be greatly reduced. Since the shoulder dropping plate has a simple configuration as described above, it can be compactly accommodated in the rotary cover, and can be mounted without complicating the structure of the tilling device by mounting the shoulder dropping plate. Furthermore, since the shoulder dropping plate of the present invention is located behind the tail wheel in the traveling direction, the resistance reaction force to the handle due to contact with the ridge is reduced, the operability is improved, and stable running is possible. It becomes.

Also, since the forming plate is mounted on the rear surface of the rotary cover that slides up and down, right and left, the position of the forming plate is adjusted in accordance with the working conditions integrally with the rotary cover, so that stable flight prevention and soil stability are always achieved. The holding effect can be realized.

Also, since the molded plate is formed of a flexible material, the molded plate can be easily mounted according to the shape of a mounting place such as a rotary cover when the molded plate is mounted. In addition, even if it hits a hard soil portion, the portion can be avoided to prevent damage.

[0024] In addition, the shape and the arrangement of the forming plate are such that a vertically long forming plate is mounted below and a wide forming plate is mounted above and below in the left and right direction. In addition to the effect of preventing splattering, the slope of the ridge can be reliably held down by the lower forming plate, and the ridge can be formed and fixed stably. Further, since the upper molded plate allows soil to be buried at the root of the crop, it plays an important role in growing the crop. As described above, the formed plate of the present invention is configured to simultaneously exert the effects of preventing the scattering of the soil, pressing the slopes of the ridges, and burying the soil at the root of the crop.
