Description

[Detailed description of the invention] In this invention, a floating plate 2 is provided on the outer periphery of the short pipe 1, and irregularities 3 and 4 are provided on the outer periphery of the plate 2 in the same plane as the plate 2. A plurality of blade plates 5 are provided on the side surface, and the blade plate 5 extends from the short pipe 1 to the middle of the side surface of the floating plate 2, and from the middle to the outer periphery there is a surrogate blade with the same side surface formed flat. A desk roller d for use is mounted behind the rear tail wheel 12 of the machine frame 8 of the tilling rotary 7 attached to the tractor with a pivot support 1 on the machine frame 8.
The horizontal shaft 6 is used to support the horizontal shaft 6 on the vertically movable link 9, and the spring 2
This relates to a paddy puddling device which is supported by a machine frame 8 in the vertical direction via a paddy field puddling device.

The short pipe 1, the floating plate 2, and the blade plate 5 are integrally molded from synthetic resin, and the short pipe 1 and the floating plate 2 are concentric and have an unevenness of 3°4.
is formed into a waveform as shown in FIGS. 4 and 5.

It is preferable to provide four blade plates 5 at an opening angle of 90 degrees, and the proximal end is connected to the outer circumferential surface of the short pipe 1, and the distal end is connected to the floating plate 2 (radius 20 degrees).
It is located at the 172 diameter position (in the middle of the side) with a radius of cm),
The area from the tip to the unevenness 3.4 on the outer peripheral edge is formed flat.

The machine frame 8 of the tilling rotary 7 is connected to the rear hitch of the tractor, and the tail wheel 12 is pivotally supported by a vertically movable fork 17 supported at the rear of the machine frame 8.

A horizontal shaft 6 is provided at the lower edge of a connecting rod 9 which is pivoted 19 to a mounting bracket 18 supported at the rear of the machine frame 8, and a short pipe 1 is freely fitted to the horizontal shaft 6, and a large number of desks are connected to each other. A roller d is supported on the same horizontal shaft 6.

The lower edge of this desk roller d is connected to the tail wheel 1 as shown in FIG.
It is held slightly higher than the lower edge of 2.

In the figure, 10 indicates the elevation adjustment lever of the horizontal shaft 6, 1 indicates the leveling plate, 21 indicates a pivot pin into which the elevation adjustment lever 10 is slidably fitted, and 22 indicates the elevation adjustment lever 1° so as to be slidable therein. a through hole that fits into the
23 is a support flange of the spring 20.

Therefore, as shown in Fig. 1, Fig. 2, and Fig. 3, the rice fields are filled with water after the wheat is harvested, and the tractor and plowing rotary 7 are used.
When the paddy field is cultivated by operating the tail wheel 12, the tail wheel 12 is supported by the ground 13 of the paddy field, and the lower part of the multiple parallel floating plates 2 at the rear of the tail wheel 12 is supported by the supporting action of the tail wheel 12 and the supporting force that allows the spring 20 to move up and down in the vertical direction. The blade plate 5 rolls around the horizontal axis 6 in contact with the ground 13 of the paddy field, and the blade plate 5 rolls downward below the water surface 14 without contacting the soil surface 15 below the water surface 14.

This transfer is caused by the movement of the floating plate 2 due to the running of the tractor, which causes the water 14 in the paddy field to push the blade plate 5 backwards, causing the blade plate 5 and the floating plate 2 to roll in the direction of the arrow, causing unevenness 3.
, 4 can push wheat straw, its stumps, grass, etc. floating on the water surface 14 into the soil surface 15 and insert it into the soil surface 15 in an upright state.

The conventional desk roller for purging has the tail wheel 12 removed and is directly fixed to the rear of the tilling rotary 7 of the tractor in place of the removed tail wheel 12, so the plowing depth of the desk roller for purging is equal to that of the tilling rotary. There was a defect that it was difficult to automatically adjust the plowing depth of the desk roller for plowing since it was determined by the plowing depth of No. 7.

Furthermore, when the floating plate is moved during driving, if the horizontal shaft that supports the floating plate tilts due to irregularities in the ground, excessive force is applied to the floating plate and it is likely to be damaged. There was a drawback in that water resistance due to movement was small and it was difficult to roll, and the force to push straw, stumps, grass, etc. floating on the water surface into the soil surface was weak, making it difficult to insert them into the soil surface in an upright position.

The present invention was developed in view of the above-mentioned defects, and since the present invention is constructed as described above, when the floating plate 2 moves due to the running of the tractor, the horizontal shaft 6 supporting the floating plate 2 may tilt due to irregularities in the ground, etc. Even if the blade plate 5 is used, the floating plate 2 is reinforced and is not easily damaged even if an excessive force is applied. The flat side surfaces can easily penetrate into the soil surface 15, and the unevenness 3 and 4 have a strong force to push wheat straw, its stumps, grass, etc. floating on the water surface into the soil surface 15, and insert it into the soil surface 15 in an upright position. As a result, it is possible to prevent missing rice plants during rice transplanting work using a rice transplanting machine, eliminate the need for supplementary planting after rice transplanting, and have the advantage of automatically adjusting the plowing depth of the plowing desk roller d.
